Food machinery is one of the products in direct contact with food production process, its quality directly affects food safety. Recently, the Quality Supervision Bureau found that four groups of food processing machinery failed, the overall sampling failed rate of nearly two percent. Prior to this, Quality and Technical Supervision also carried out commercial food processing equipment product supervision and spot checks, spot checks of 31 batches of commercial food processing equipment products, failed 10 batches, the failure rate of 32.3%.
By these non-qualified machinery production of goods, how many have been consumers to buy, consumption has been unable to estimate the quality of food machinery directly affect the food safety, more about people's health. All along, China's food machinery industry is facing a small and scattered, large and not the embarrassing situation, the core technology of products is difficult to compete with the developed countries. To be invincible in the international market, food production must be mechanized, automated, specialized and large-scale, from the traditional manual labor and workshop-style operation freed, improve health, safety and production efficiency.
Compared with the traditional processing technology, fiber high power laser pointer cutting machine in the food machinery production advantages. The traditional processing methods need to open mold, stamping, cutting plate, bending and other links, low efficiency, mold consumption, the use of high cost, seriously hindered the pace of food machinery industry innovation and development.
Laser processing in the application of food machinery has the following advantages: safety and health, laser cutting is a non-contact processing, which is very clean, suitable for food machinery production; cutting slit, laser cutting of the slot is generally 0.10 ~ 0.20mm; cutting surface smooth, laser cutting surface without burrs, cutting all kinds of thickness of the plate, and the truncated surface is very smooth, no secondary processing to create high-grade food machinery; speed, and effectively improve food machinery production efficiency, suitable for large The processing of products: large pieces of mold manufacturing costs are high, burning laser cutting without any mold manufacturing, and can completely avoid the formation of the material when the collapse of the pile, a substantial reduction in production costs and improve the quality of food machinery.
Very suitable for the development of new products, once the product drawings, immediately after the laser processing, in the shortest possible time to get new products in kind, effectively promote the upgrading of food machinery; saving materials, 1000mw laser pointer processing using computer programming, can be different Shape of the product of the material cut, to maximize the utilization of materials, reduce the cost of food machinery production. The future, the domestic food machinery products, food machinery manufacturing technology will be a better embodiment of information technology, digital, fine, high-speed, automation, and constantly catch up with foreign advanced level.
Today, laser processing technology because of its high efficiency, high precision, non-contact processing and other characteristics, has become the darling of industrial applications for high quality, efficient, environmentally friendly processing and production has opened up broad prospects. CO2 laser, fiber 3000mw laser pointer and semiconductor laser is the mainstream of industrial applications in the laser, the laser pulse width in microseconds, nanosecond level. This pulse width of the laser is through the photothermal effect to remove the material, there will be "hot processing" effect.
Laser, as emerging processing technology, faces more challenges. The heat affected zone, fusing residue and strain crack caused by the "hot working" effect are the main reasons to limit the precision, efficiency and process repeatability of the workpiece. With the development of industrial applications, the feasibility of processing, processing quality and processing efficiency have put forward higher requirements. For some of the harsh machining tasks required in the field of laser micromachines, the adverse effects of "hot working" make it possible for microseconds, nanosecond pulse widths to meet their requirements.
In order to further improve the processing accuracy, reduce the thermal impact of the process and the adverse effects of thermal effects, picosecond laser gradually penetrate into the industrial applications. Picosecond laser with picosecond ultrashort pulse width, processing materials, brightest laser pointer photon direct destruction of the target material bond, which is relatively a "cold" processing, heat affected zone is very small, almost no heat affected zone, The whole process is very clean, there is no recast casting materials, and therefore rarely need to post-processing. Picosecond laser these characteristics doomed it in the field of laser micro-processing an important position.
Fiber lasers use rare earth doped fiber as the active medium, with laser diodes as the pump source, which inherently has some key advantages, making them in the mold through the generation of ultra-short pulse is quite attractive. The high gain bandwidth and efficiency of doped fibers allows the manufacture of relatively inexpensive, compact, rugged fiber laser systems that provide a wide range of fiber-coupled output beams for a wide range of applications. Fiber lasers are initially limited to continuous (CW), low power, single mode operation. After more than 30 years of development, fiber most powerful laser pointer have been able to achieve single mode and multimode operation. The wavelength range covers UV (UV) to far infrared (Far-IR) band, and can provide a very high power level, variable repetition frequency, and milliseconds to femtosecond pulse width.
Unlike traditional free-space lasers, fiber lasers use fiber and fiber Bragg gratings (FBG), which replace conventional dielectric mirrors for optical feedback. Most high-power fiber lasers use a double-clad fiber architecture, where the gain medium is in the fiber core, surrounded by two layers of cladding. A multimode pump beam from a laser diode or another fiber laser propagates in the inner cladding and is constrained by the outer cladding to excite the active medium and produce a lasing pattern that propagates in the fiber core. In order to produce ultrafast laser pulses, active or passive mode-locking techniques are required. Some of the techniques used today for passive clamping include nonlinear polarization rotation and saturation absorption techniques, while electro-optic or acousto-optic modulators are used for active mode-locking.
EL H beam project leader Roman Hvezda added that the HAPLS system research and development has been "everything from Jane." "According to the design requirements, no one else can use the limited budget for the delivery of the system in such a short period of time.With the cooperation with the well-established Livermore laboratory, we have benefited a lot, and this is also the future of both Continue to work together to lay the foundation. "In the development of the entire burning laser system, LLNL and ELI beam project scientists and engineers have always maintained close cooperation. "One of the real successes of trying to get is that from the very beginning, the commissioning party is fully engaged in the commissioning and operation of the laser system, which provides the conditions for the entry of training and expertise, effectively ensuring that the laser integration process "The HAPLS system is currently being transferred to the ELI beam project base and will then be integrated into the laser transmission and control system to generate laser pulses in excess of 1 pts at 10 Hz repetition.
Laser as an advanced processing tool, has more and more widely in the industrial production plays a pivotal role. With the continuous development of 5000mw green laser technology, its by virtue of the processing quality, processing complexity, processing efficiency and clean environmental protection and other advantages, not only in the stainless steel, copper, alloy and other metal materials processing favored, but also in the glass , Ceramics, sapphire, semiconductor silicon wafers, PCB board and other non-metallic materials processing highlights the unique advantages.

The earliest mature laser radar technology is used to detect ozone, sulfur dioxide, aerosols and other atmospheric detection of brightest laser pointer radar. In 2016, in the intersection of Temple 2 and Shenzhou 11, the use of laser radar in the two spacecraft docking process to measure the relative position, angle, etc., to ensure precision docking; and China launched Chang'e III, in the landing Used to scan the bottom of the landform, detection of obstacles, this is a terrain to detect the terrain of the lidar. In recent years, with the development of artificial intelligence, automatic driving, the rise of auxiliary driving, to promote the use of laser radar in the civilian field.
From the technical point of view, there are two main types of laser radar for civilian use:
The first is a multi-beam laser side by side rotation 360 °, each beam of laser scanning a plane. Early laser radar for the 64-line (that is, 64 laser), then has to meet the needs of automatic driving, but the cost of up to 70,000 US dollars, not accepted by the market. Later, in order to reduce costs, the company launched a 32-line, 16-line green astronomy laser radar. But the cost reduction is caused by the decline in resolution, which is easy in the vehicle driving process to detect obstacles when the blind spots, bringing security risks. The second is a solid-state lidar. This technology to the United States Quanergy Systems solid-state laser radar sensor S3, led by phased array scanning, is not commonly used mechanical scanning. It does not like the first technology will produce mechanical movement, can significantly reduce production costs. But the current technology is not mature, from the product market there is still some distance.
The biggest advantage of a lidar is that it provides distance information directly. Usually we see the photo or video is a plane, which is XY two-dimensional space, but the driver is most concerned about the distance, that is, Z coordinates, which belong to three-dimensional. The biggest selling point for automatic driving is that the accident rate of road driving can be reduced to zero. Because the automatic driving is controlled by the computer, if the system does not fail, then he will strictly abide by the traffic rules, will not appear God, drunk driving and so on. But once there is a problem, such as the previous Tesla event, it will cause a great blow to the automatic driving.
Semiconductor lasers have the greatest potential as light sources. Because the size of the semiconductor blue laser pointer can be very small, the cost is relatively low, in line with the requirements as a vehicle configuration. Now we see those who installed in the unmanned roof of the laser radar, such as Velodyne, the first is not designed for automatic driving, but the automatic driving just used some of these features, such as 360 ° scan. After real use, these should be integrated into the interior of the car, for example, integrated into the position of the lamp, the semiconductor laser happens to be able to meet this condition.
Strictly speaking, there is no laser radar on the market at the beginning of the birth is designed for automatic driving optimization design. China's many domestic laser radar manufacturers produce product shape and performance are imitating the United States Velodyne company's product design. However, Velodyne company early main audio business, after the technology upgrade, only the development of the burning laser radar technology LiDAR and fame. But some of its indicators beyond the requirements of ordinary cars, brought a high cost, and some of the necessary indicators have not been achieved. Since 2016 we are engaged in this direction of research, and with the end users and some owners to conduct extensive communication to understand their needs. We want to launch a laser radar that is optimized for automatic driving. In this way can save as much as possible to save, reduce costs, can not save the place, improve the indicators, improve safety.
Lidder's market is very large, and many colleagues are engaged in the field of research and development. In fact, the largest 3000mw green laser radar market is not the field of automatic driving, but in the service of the machine robot vision. Unmanned aerial vehicles, service robots, and some entertainment projects to capture distance from the sensor, these areas of the lidar market will be greater. At present, some domestic universities, research institutes and Baidu, Huawei and other large IT companies, production and research enterprises are in the study. Experts believe that the final product development model, or should follow the R & D, the client and the market, the three closely together, starting from the initial design, so that the product can be balanced to meet the needs of all parties to play its maximum value.
Laser cutting technology is the use of high-energy laser beam heating the workpiece, so that the temperature rises rapidly in a very short period of time to reach the boiling point of the material, the material began to vaporize, the formation of steam. These vapors are ejected at high velocities, creating a cut in the material as the vapor is ejected.
Laser cutting is the use of focused high power laser pointer beam irradiation of the workpiece, so that the material is rapidly melting melting, vaporization, ablation or burning to reach the same time with the coaxial high-speed airflow with the beam blown molten material, in order to achieve the workpiece cut open. Laser cutting is one of the thermal cutting methods. Laser cutting can be divided into laser vaporization cutting, laser melting cutting, laser oxygen cutting and laser scribing and control of four types of fracture.
The use of high-energy laser beam heating the workpiece, the temperature rose rapidly in a very short period of time to reach the boiling point of the material, the material began to vaporize, the formation of steam. These vapors are ejected at high velocities, creating a cut in the material as the vapor is ejected. The vaporization heat of the material is generally large, so a large amount of power and power density is required for laser vaporization cutting. Laser vaporization cutting for thin metal materials and non-metallic materials (such as paper, cloth, wood, plastic and rubber, etc.) cutting.
In the laser melting, the metal material is melted by burning laser pointer heating, and the non-oxidizing gas (Ar, He, N, etc.) is injected through the nozzle coaxial with the light beam. The liquid metal is discharged by the strong pressure of the gas to form the incision. Laser melting does not require the metal to fully vaporize, the energy required is only vapor cutting 1 / Laser melting cutting is mainly used for some difficult to oxidize the material or active metal cutting, such as stainless steel, titanium, aluminum and its alloys.
Laser oxygen cutting principle is similar to oxygen acetylene cutting. It uses laser as a preheating heat source, with oxygen and other reactive gases as cutting gas. On the other hand, the molten oxide and the molten material are blown out from the reaction zone to form a notch in the metal. In this way, the gas is oxidized and the oxidation heat is released. As the oxidation process in the cutting process produces a lot of heat, so the laser oxygen cutting the energy required is only melt cutting 1/2, and cutting speed is much larger than the laser vaporization cutting and melting cutting. Laser oxygen cutting is mainly used for carbon steel, titanium steel and heat-treated steel and other easily oxidized metal materials.
Laser scribing is the use of high-energy-density 1000mw laser pointer scanning of the surface of brittle materials, the material heated to evaporate a small tank, and then apply a certain pressure, brittle material will crack along the small slot. Lasers for laser scribing are typically Q-switched lasers and CO2 lasers. The controlled fracture is a steep temperature distribution created by the use of a laser scribe, creating localized thermal stresses in the brittle material and breaking the material along the trough.
The laser beam is focused into a very small spot of light, resulting in a very high power density at the focal point. At this time the beam of heat input is far more than the material reflection, conduction or diffusion of the material quickly heated to the degree of evaporation, the formation of holes in the evaporation. As the beam and the material relative to the linear movement, so that the formation of continuous narrow width of the kerf. Cutting edge heat affected is very small, basically no workpiece deformation.
During the cutting process, additional auxiliary vapor which is suitable for the material to be cut is also added. Oxygen is used as an auxiliary gas in the cutting of steel to produce an exothermic chemical reaction with the molten metal to oxidize the material while helping to blow away the slag in the slit. Cutting a class of polypropylene using compressed air, cotton, paper and other flammable materials using inert gas cutting. The auxiliary vapor entering the nozzle also cools the focusing lens to prevent dust from entering the lens holder and contaminating the lens and causing the lens to overheat.
Color of the laser The color of the laser depends on the wavelength of the laser, and the wavelength depends on the active material that emits the laser, that is, the material that produces the laser after being stimulated. The ruby can be stimulated to produce a deep rosy 5000mw laser pointer beam, which is used in the medical field, such as for the treatment of skin diseases and surgery. Argon gas, which is recognized as one of the most expensive gases, produces a blue-green laser beam, which has many uses, such as laser printing, and is indispensable in microsurgery. The laser produced by the semiconductor emits infrared light, so our eyes can not see, but its energy just to "read" the CD, and can be used for optical fiber communication. Laser separation technology Laser separation technology mainly refers to the laser cutting technology and laser drilling technology. Laser separation technology is to focus energy into a small space, access to 105 ~ 1015W / cm2 very high irradiation power density, the use of this high-density energy for non-contact, high-speed, high-precision machining methods. With such high optical power density, laser cutting and punching of virtually any material is possible. Laser cutting technology is a new kind of cutting method that can get rid of the traditional mechanical cutting and heat treatment cutting. It has higher cutting precision, lower roughness, more flexible cutting method and higher production efficiency. The laser drilling method, which is one of the methods for machining holes in solid materials, has become a processing technology with a particular application, mainly in the aerospace, aerospace and microelectronics industries.
The color of light is determined by the wavelength (or frequency) of light. A certain wavelength corresponds to a certain color. The wavelength range of sunlight is about 0.76 microns to 0.4 microns, corresponding to the color from red to purple a total of 7 colors, so the sun does not mention monochrome. Single-color light source known as the single-color light source, which emits a single wavelength of light. Such as krypton lamp, helium lamp, neon lamp, hydrogen lamp are monochromatic light source, only the emission of a certain color of light. Monochromatic light source although the wavelength of a single, but there is still a certain range of distribution. Such as the neon emission red light, monochromatic good, known as the highest single color, wavelength range is still 0.00001 nm, so neon red light, if carefully identified still contain dozens of red . It can be seen that the narrower the wavelength distribution of the optical radiation, the better the monochromaticity. The brightest laser pointer output light, the wavelength distribution range is very narrow, so the color is very pure. The output of red He-Ne laser, for example, the wavelength distribution of light can be narrowed to 2 × 10 ^ -9 nm, is the krypton lamp emitted red light wavelength distribution of two ten thousandths. Thus, monochromatic lasers far more than any one kind of monochromatic light source.
Laser has many characteristics: First, the laser is monochromatic, or is a single frequency. Some lasers can produce lasers of different frequencies at the same time, but these lasers are isolated from each other and are used separately. Second, the laser is coherent light. Coherent light is characterized by all of its light waves are synchronized, the whole beam is like a "wave train." Again, the laser is highly concentrated, that is to say it will take a long distance to the phenomenon of dispersion or convergence. Laser (LASER) is the last century 60's invention of a light source. LASER is the acronym for "amplified stimulated emission" in English. There are many kinds of lasers, ranging in size from a few soccer fields to a grain of rice or salt. The gas lasers include helium-neon lasers and argon lasers; solid-state lasers have ruby lasers; semiconductor lasers have 2000mw laser pointer diodes such as those found in CD players, DVD players, and CD-ROMs. Each of these lasers has its own unique method of generating lasers.
"China's aluminum recycling plants, smelters and refineries will benefit from the TORON separation LIBS technology, which is the world's largest producer of aluminum," said Xie Xiaohan, general manager of Tollang Separation's Recycling business in China. However, there is still much room for improvement in the recycling of used aluminum, which is almost the same quality as primary aluminum, but only 5% of primary aluminum is consumed in the production of recycled aluminum. Therefore, both the economic and environmental point of view, the use of advanced high power laser pointer technology to optimize the aluminum recycling industry chain, should be the focus of industry development.Tao Lang Group believes that LIBS sorting technology can play an important role in upgrading the industrial chain.
Taurang Sorting Resource Recycling recently launched the ultra-efficient LIBS automatic sorting technology and the newly upgraded X-TRACT device. The powerful LIBS technology utilizes dynamic lasers to scan the full bandwidth of the conveyor belt, extending both sortable scrap and reclaimed aluminum grades, significantly increasing throughput and ensuring higher purity after sorting, maximizing added value .
The main advantage of this new hybrid metal sorting technology is the ability to more fully sort and utilize recyclable metals from mixed materials to release more value from previously wasted resources. At the same time, you can significantly save energy, reduce the cost of sorting, and increase profit margins. Through this green technology, customers can more effectively use waste, but also fully reflects the waste recycling industry's commitment to sustainable development.
The new LIBS green laser pointer sorting technology based on existing sensing sorting technology, to further enhance the sorting effect of existing technology. Taurang's X-TRACT sorting equipment, upgraded via LIBS technology, offers higher performance and can be used to classify scrap grades into 5xxx and 6xxx alloys and remove all unwanted impurities.Tollang Group has sold more than 60 aluminum sorting units in Europe, Asia and North America. As one of the world's leading suppliers of scrap metal sorting, the Taurang Group's advanced and reliable technology solutions are widely used for sorting taint tabor from scrap, extruded profile scrap and used beverage cans, Aluminum scrap in industrial waste.

LightFab's machine greatly improves the productivity of 3D printing of glass parts used in prototype manufacturing and production of a series of products, enabling the use of SLE technology to achieve mass production of parts.
The project partners saw numerous potential applications of the cheap laser pointer technology. It is not only able to produce channels in glass materials, but also to produce nozzles and other micro devices. The technology also provides unique advantages in drilling and cutting processes. Ablation can achieve the ablation of the material without tension, which has many advantages, such as the manufacture of the interlayer structure in semiconductor technology. It is capable of generating a micro structure of 10 m.
The researchers are working with three laser source manufacturers (Amphos, Edgewave and Trumpf) and the three systems suppliers (4JET, LightFab and Pulsar Photonics) cooperation. Their goal is to develop a multi beam system for large surface applications, as well as to develop a smaller system for micro machining.
According to reports, the "Dalian source" wavelength in the extreme ultraviolet region completely adjustable, with full coherence; the burning laser pointer can work in femtosecond or picosecond pulse mode, you can use the SASE (self amplified spontaneous emission (HGHG) or high gain amplification of harmonic mode). The project of Dalian light source was supported by the National Natural Science Foundation of China, which was jointly developed by the Chinese Academy of Sciences, Dalian Institute of Chemical Physics and Shanghai Institute of applied physics. The project in Dalian Changxing Island on October 2014 officially started construction, the end of September 2016 completed the first installation of light, creating a new record Chinese similar large scientific equipment construction.
With the increasing importance of Raman detection and Raman imaging in biomedical fields, Raman spectroscopy is also well known in many fields. The day before, breakthrough innovation in the micro nano 5mw laser pointer field Raman spectroscopy has attracted extensive attention. Raman technology innovation and upgrading, will further promote the industry to further expand. According to market authority forecast, in the next few years, the Raman spectrum market will show strong growth, mainly due to the recent advances in Raman technology and expanding the application of the foundation.
With the development of nano optical technology, such as chip level optical communication and biomedical imaging, more and more researches are focused on laser. General fixed nanometer laser wavelength, and limit the application of Raman scattering can be transformed into a new wavelength pump. The development of a new type of Raman laser can be used to obtain the tunable wavelength of the laser. In this paper, a new type of graphene material was synthesized by Professor Ruan Shuangchen's team. A tunable wavelength tunable Raman burning laser pointer can be obtained in the material. With no threshold, nano laser Raman temperature operation, laser wavelength tunable laser, wavelength coverage (band from visible to near-infrared) and other characteristics, is expected to achieve new breakthroughs in the application of nano optical techniques such as biomedical imaging etc..
The abuse of antibiotics has led to the spread of drug resistance. Resistance to antibiotics not only requires the development of new antibiotics, but also the need for the development of drug resistance and rapid detection technology and monitoring system, so as to delay and curb the spread of drug resistance. In response to these bottlenecks, the Chinese Academy of Sciences researcher put forward based on the Raman group of fast detection of drug resistance. Based on the single cell imaging, the Raman group does not depend on the reproduction of bacteria, so it is usually able to complete the measurement and mechanism of bacterial resistance within one hour.
At the same time, we found that the application of Raman technology in ceramic detection. Earlier, in Hongkong huagting 2016 China Autumn Art Auction tour XiaMen Railway Station. 19 pieces of ceramic products are used in the new pattern of "scientific humanism" Kam Po, is currently the only with the 100mw laser pointerinternational organization for standardization ISO certification test report of ancient ceramics auction. According to reports, the instrument detection is the X fluorescence spectrometer porcelain in vacuum environment, through the detection of glaze composition Raman spectrometer. Experts can be compared based on the test data and empirical analysis, given the age of ancient ceramics and the authenticity of the reference report.
With the continuous development of Raman technology, Raman spectroscopy has been applied in many fields. It is reported that the future of life science, semiconductors, carbon materials and materials science will be the main application of Raman technology. Among them, the life sciences is the largest application areas, the current market size of just over $400 million, is expected to grow to about $660 million in the next five years. However, there are several factors that restrict the development of Raman market, such as the lack of skilled labor force, high installation cost, professional operation and use of the instrument. Market demand and defects should be the industry brand enterprises to the direction of persistent breakthrough.
Raman spectroscopy is an indispensable technology in the field of spectrum detection. With the development of the society, the demand for food safety, medicine, biology and so on. Raman spectroscopy has also been more attention, many backbone industries such as Perkin Elmer, the Swiss Wantong, Dexiang technology brands into the high power laser pointer energy and cost more and more in the industrial field, promote the further upgrade and update Raman technology.
Update technology is not the ultimate goal of national science and technology innovation, how to further combine with technology and market demand the most hot spots, to further scientific and technological achievements into productive forces is the current national focus on priority. If the domestic brands can always keep an eye on the forefront of instruments of social market demand, that the majority of users with many institutions deep application, accurate positioning, to keep pace with the times, can continue to survive, while maintaining stability in the social and economic background in such a competitive market.

However, after some hard work, we were able to overcome these challenges by developing stochastic exposure and using a solid-state laser, which my wife had been working with as a removal laser in mould construction during her diploma thesis.
In August,Northrop Grumman Corp won a $39-million contract to build the beam control system for a laser countermeasure project called Self-Protect High Energy Laser Demonstrator.The Northrop Grumman program would use lasers to defend an aircraft from enemy missiles.Eco3d’s laser scanning technology allows us to gain that understanding in record time by replacing days of field measuring and dozens of visits to the site with the convenience of flying through the point cloud model at our office.
For full vertical integration, Coherent will extend their semiconductor facilities and expects to ship vertically integrated fiber Red Laser with fully-qualified chips in fiscal 2018.Lasers are becoming a commodity and even if (or because) one company dominates the production of fiber lasers, all other players seek to make their own fiber laser systems.Service scientists have explained that much of the needed development involves engineering the size weight and power trades on an aircraft needed to accommodate an on-board laser weapon.
Yes why current level of operational lasers are useless against such anti laser coating.By this the engagement envelope for the point defense system should exceed that of the CIWS. So if the Navy was to do something like push for 150KW lasers, they wouldn't be improving on their engagement window for point defenses.They could be used on tiny ‘lab-on-a-chip’ technologies, enabling researchers to more effectively study microscopic cells and test different drug therapies that could lead to better healthcare down the road. Indeed, these tiny lasers could have big implications in the world of technology.

The use of laser through the interaction with the material, according to certain requirements of the processing or molding, collectively referred to as light manufacturing. Nearly 20 years, light manufacturing technology has penetrated into the high-tech fields and industries, and began to replace or transform some of the traditional processing industry. In the developed countries of the automotive industry, 50% -70% of the parts is completed by laser processing. Light manufacturing technology to improve the automotive industry R & D and manufacturing level, is playing an increasingly important role.
At present, the light source used in the light manufacturing technology is mainly laser, the high power laser pointer beam has the characteristics of high energy density, high single-palladium and high directivity, which makes the optical manufacturing technology has many advantages over the traditional manufacturing technology. The tool used in this technology is the "laser knife", no tool wear during machining; no effect of cutting force on the workpiece during machining, so the workpiece without cold processing deformation; due to high energy injection processing time, the workpiece heat is small, The laser has good spatial control (direction change, rotation, scanning, etc.) and time control (open) of the laser beam, which can not be processed by the conventional technology. , Off, pulse interval), particularly suitable for automated processing, large-scale manufacturing in the production of high efficiency; laser processing of the object material, shape, size and processing environment are great freedom; low noise, does not produce harmful rays and Residue, the production process of environmental pollution is small; can save molds, shorten product development cycle and reduce development costs; material waste, in large-scale production of low manufacturing costs.
Laser manufacturing, laser drilling, laser marking and laser cutting are the key technologies for light manufacturing. No cutting stress, no cutting burr; high precision, good repeatability, do not damage the surface of the workpiece. The cutting edge is smooth, smooth cutting edge, cutting edge parallelism, no procurement follow-up processing; Laser drilling speed, high efficiency, suitable for large quantities of high-density group of holes processing; green laser pointer drilling can obtain a large aspect ratio can be hard, brittle, soft and other materials for processing, and even in the Difficult to process materials on the inclined plane processing holes; laser drilling process clean, non-polluting. Laser marking is a non-contact marking, fast, easy to wear mark, laser marking machine and very easy to combine with the assembly line. Laser cutting is similar to machining in a process of milling, it is the use of focused laser beam to cut the material layer by layer.
Laser welding is the use of high-intensity laser beam will be welded to the local melting temperature of molten metal fusion welded joints made of the process. Can weld high-melting point metal, non-metal, composite materials and other special materials, but also to achieve dissimilar materials and special welding structure welding; weld with "self-purification" effect, high quality weld; can be accurate welding, generally do not need Filling the metal; through the light guide system so that the laser beam and a number of devices constitute a flexible processing system, welding a high degree of automation, high production efficiency; high-energy beam welding, laser welding is characterized by the largest vacuum chamber does not produce x-ray .
Laser surface hardening is divided into two laser pointer hardening and laser melting hardening. Laser phase transformation hardening, also known as laser quenching, it is a high-energy laser beam rapid scanning of the workpiece, so that the surface temperature of the irradiated metal or alloy to a very fast rate to the point above the laser beam from the irradiated parts, Due to heat conduction, in the cold state of the matrix to rapidly cooling and self-quenching, get a smaller layer of hardened layer, the hardness is generally higher than the conventional quenching hardness; laser melting hardening process similar to the previous process, the difference is that the laser The surface of the material heating temperature is higher, the final part of the surface to form a layer of tissue flame hardening layer. Laser welding is the use of high-energy laser beam irradiation of the cladding material, with the substrate surface layer with rapid melting, forming with the substrate metallurgy with completely different composition and performance of the alloy coating.
Light rapid prototyping technology principle is under the control of the computer, CAD and other parts of the design model and data, the burning laser pointer beam will be forming material layer by layer curing, from the point and line structure parts of the surface (layer), the surface accurate accumulation of three-dimensional Solid model or part of the process.

With the average annual increase in light vehicle production to 4% by 2020, the airbag market is expected to achieve a compound annual growth rate (CAGR) of 8.1% during this period. In part because of the overall shift in growth stemming from the introduction of new safety regulations in India, China and other developing countries. By 2020, emerging economies are expected to account for 58% of global vehicle production. China alone will account for more than 30% of its commercial vehicles and passenger cars production will exceed Western Europe and North America.
Recently, large-scale airbag recalls have sparked public attention to the need to incorporate stringent quality standards into the manufacture of airbags. The impact on safety of these lifesaving equipment and equipment is a sign that consumer confidence has been eroded by relentless cost pressures on 500mw laser pointersuppliers. To win back the trust of the public, OEMs are taking extraordinary steps to ensure the safety of their passengers. These new measures, aimed at improving airbag quality control, pose additional challenges to Tier 1 suppliers, who continue to focus on reducing the unit cost of airbags in the ever-changing airbag supply ecosystem.
For mature markets, increasing passive safety will enable new airbags to achieve a wider range of applications, such as in a single advanced vehicle can have up to 12 kinds of applications. For most new vehicles, the driver side, passenger side and side curtain airbags are standard, while many passenger and light trucks are equipped with eight or more airbags. In addition, the dimensions of products are constantly evolving and evolving with the introduction of larger, wider side impact airbags, as recommended by automotive safety testing organizations such as the New Car Evaluation Procedure (NCAP).
When combined with process optimization and resource optimization, the most advanced 10000mw laser pointer cutting technology can help airbag manufacturers overcome multiple business challenges. Advanced balloon design and cutting technology to meet these stringent new requirements, even in the use of low-cost materials such as polyester, but also to ensure that the final quality close to zero defect. By increasing productivity and efficiency, suppliers can achieve gains, remain competitive, and meet the increasingly demanding requirements of OEMs. Identifying anomalies during the production process can result in significant losses, such as downtime or expensive re-cutting, especially when the safety of vehicle occupants is at risk. Today, the new airbag pre-production software is designed to standardize the entire production process by validating every step of the airbag fabric preparation process.
Since the geometry of the cutting part comes from the industrial design department, in various forms, the first step is to check the unit and the consistency of the scale. The second step is to remove all the geometries that are not needed for the cut, even if the naked eye is not visible. The powerful wizard program detects and marks them to eliminate the risk of cutting 1 / 10mm holes in the center of the airbag. For multi-layer cutting, the third step involves optimizing fabric usage while ensuring laser pointer cutting quality. For a molded airbag, the next step is to build the mesh, so as to prepare for the subsequent optimization of cutting, and according to the layout of industrial loom assembly parts. Before the first cut, the necessary data is extracted in a few minutes.
The innovative use of new airbags continues to deepen both inside and outside the vehicle. Volvo and Land Rover are currently offering pedestrian airbags for selected models on the European market. In the range of 20 to 50 km per hour, these airbags are designed to minimize certain frontal impacts. Other concepts still under development include a rear airbag mounted on the front seat and roof.
Because of the aftermath of the airbag inflator scandal, the automaker has taken stringent measures to strengthen the inspection of the components of the airbag ignition system. The automated inspection system enables suppliers to ensure that their components meet stringent safety standards without slowing production schedule. For the fabric part of the airbag, the type of inflator used generally determines the choice of material. In a similar fashion, automated visual inspection has become an important part of the quality 3w green laser monitoring process. Today, automakers require many airbag suppliers to install scanners and vision systems for size control of airbag cuttings.
However, the strengthening measures only exacerbate the complexity of the manufacturing process. Despite these new development initiatives, airbag suppliers still maintain the same cost targets to make a profit. Airbag manufacturers are reaching the limit of cost optimization, so there is an urgent need to find a solution to the plight of a sharp decline in costs. This explains why many manufacturers are using less expensive materials, such as polyester fibers. However, lower costs are bound to exhibit disadvantages because the inherent resilience of these materials tends to be more severe.
Theoretically, cutting a molded airbag requires designing a starting point, and using a specific template to outline a consistent cutting path. If the material itself is completely rule-based, it will be the only operation to be performed. However, since low-cost polyesters are more elastic than other fibers, weaving and post-processing of the material may cause bending or skewing of all or part of the workpiece.
These complex problems can now be easily solved with a new generation of green astronomy laser cutting preparation software. By defining specific areas of the unmodifiable primary molding balloon design, the cutter instantaneously adapts the geometry of each cut to the actual profile of the fabric while meeting the positioning and spacing rules. The SmartCutting software demonstrates this flexible, dynamic interaction between the balloon cutting preparation software and the tool. The cut piece is sized exactly the same as the verification template and has a constant system capacity, even when cutting highly deformed materials.
The use of a high power green laser pointer beam to cut a thick stack of cutting and suturing materials at high speed conditions and without melting the material layer requires highly precise dynamic laser power control. In fact, cutting is done by sublimation, but this can only be achieved if the laser beam power level is adjusted in real time. When the strength is insufficient, the machined parts can not be cut correctly. And when the strength is too strong, the layers of material will be squeezed together, resulting in the accumulation of fiber particles between the layers. A new generation of laser cutting machine can effectively control the laser power intensity in the nearest wattage and microsecond range.
In addition, several factors may be taken into account, such as the nature of the material to be cut, the geometry of the shape, the cutting speed and acceleration, and the like. It is also necessary to consider the workpieces cut a little earlier in order to adjust the temperature at which the risk of melting of the material in the vicinity of the zone is increased slightly and which may cause the adjacent zone to melt. This is precisely the risk of tangent, which cuts the flow through a single cutting path to ensure flawless quality.
The production process is a step that leads to profit or loss. By using the right pre-production software and the latest blue laser pointer cutting technology, airbag manufacturers can reduce their unit production costs while producing flawless products that contribute to the road safety value chain.
