Laser anti-counterfeit label printing technology by the international printing community as the twenty-first century new printing, laser holographic anti-counterfeit labels is the use of the technology of laser-molded hologram products. Laser hologram is a combination of technology and art high-tech products, mainly used for anti-counterfeit goods trademarks and important documents, ID cards, credit cards, passports, currency and other security labels. Some famous domestic and foreign special products also use these trademarks. As an art deco, development of three-dimensional holographic product packaging materials, blue laser holographic printing technology is also widely used.
Holographic holographic products have three major characteristics: large-scale industrial production can be carried out; under the illumination of light reproduction of three-dimensional pattern, the color changes with the observation of the location changes; high productivity and low cost.
Due to the unprecedented development of the commodity economy, market competition has become increasingly fierce. Product counterfeiting has taken place repeatedly. The spread of the product is so widespread that it is far more detrimental to the quality of counterfeiting. In order to prevent forgery, scientists carried out research on anti-counterfeiting technology. After decades of research, they proposed that "laser-embossed holography" should be used instead of the existing plate-making printing trademarks, thus effectively preventing trademark counterfeiting. At present, red laser pointer hologram labels are widely used in salt, imported food, cigarettes, pharmaceuticals, home appliances and other fields. At the same time, due to the characteristics of the laser holographic packaging material beautifying packaging and security, not only for the product to increase security, but also for the product to create a high-end image, enhance product quality, so as to create a good shelf effect, more and more enterprises and Brand accepted. At present, it is widely used in tobacco, alcohol, cosmetics and other higher value-added products and pharmaceuticals, food, automotive supplies and other industries.
Many electrical industry in the appearance of sheet metal parts and complete sets of electrical components used in the installation of laser cutting machine processing technology, reducing production costs, received a better production efficiency. Laser cutting machine in the electrical industry is mainly used for the appearance of sheet metal parts and complete sets of electrical components in the installation of thin steel parts for cutting. Nowadays, after adopting this new technology in many electrical appliances factories, the product quality is raised, the production cost is reduced, the labor intensity is reduced, the traditional plate processing technology is improved, and the better production benefit is received.
Laser cutting is a high-tech developed in recent decades, which has higher cutting precision, lower roughness, higher material utilization and production efficiency than the traditional cutting process, especially in the In the area of fine cutting, high power laser cutting has something that can not be compared with conventional cutting. Laser cutting is to focus the energy to a small space, the use of high-density energy for non-contact, high-speed, high-precision cutting method.
In the process of electrical manufacturing, there are many metal parts and parts, and the shape is complex, and the process is very difficult. In the process of processing, a large number of tooling and mold are needed to ensure the quality of processing. The laser cutting technology in the electrical industry, not only can effectively solve the above problems, but also to improve processing quality, save processing and processing costs, shorten the manufacturing cycle, reduce labor and processing costs, improve processing efficiency and other large format plays an important role and value.
High-brightness fiber lasers (beam parameter product [BPP] <1.5 mm-mrad) enables system integrators to achieve remote machining, enhance the safety of remote machining heads in operation, and by combining with the fast positioning beam scanning head To achieve the aluminum, copper and other high thermal conductivity metals, as well as new, lightweight carbon fiber composite materials, remote blue laser cutting, etching and welding. High-power, high-brightness fiber lasers make rapid laser scanning (RLS) applications rapid development. Compared to other technologies, RLS has greater flexibility and faster processing speed, and greatly reduced the processing of large-size workpiece cycle.
Conventional fiber lasers use fiber-coupled technology to couple multiple beam outputs together, resulting in lower brightness of the output laser. The new generation of fiber lasers uses an innovative architecture that combines the pump diodes and drivers into separate pump modules. The gain fiber is mounted in a configurable gain module that can output more than 8kW of laser power. The gain module is based on the novel main oscillator / power amplifier (MOPA) design, enabling high-brightness laser output. In addition, the Ennie laser pointer also uses a reliable integrated backlash isolator to protect all modules from the impact of backlit light, can be high anti-material full power, uninterrupted, stable processing. These two technological innovations play a vital role in RLS applications.
The key to the design of the RLS system is the working distance of the scanning head, the size of the focal spot, and the scanning range. One advantage of using a high brightness fiber laser is that it can increase the working distance and scan range while achieving a smaller focal spot size to increase the welding speed and increase the weld penetration. The two commercial RLS scan head products (SCANLAB IntelliWELD and IntelliSCAN) listed in the table show the benefits of higher brightness lasers (50 μm fiber core). From this example can be seen, the scanning head working distance can be increased by more than 50%, while the focal spot size can be reduced by 14%. nLIGHT lasers can provide high brightness output up to 8kW.
The choice of welding solution is a complex issue for each application. In general, the more the number of short welds is, and is distributed over a large area (eg, door, seat structure, and bodywork of the car assembly). Compared to fixed optical head welding, remote astronomy laser pointer welding (RLW) advantage is greater. The following figure shows the use of RLW technology to shorten the processing cycle as high as 50% of the case. The example also covers high-density welds, precision soldering (a, b), and large-size structural welds with multiple welds. In particular, we see from (c) that part of the weld of this part continues from the top plate to the floor. This type of structure using the traditional welding head welding is not easy to achieve.
In addition, RLW can provide many advanced functions for welding process control. For example, if it is necessary to swing the welding point in the welding area, or if the machining process involves complex welding shapes (round, C, etc.), the scanning speed And the accuracy will be better than the use of small-scale high-speed movement of the robot. RLW scanning head scanning speed can reach 90 to 180m per minute, while the traditional robot movement speed of only about 10m / min.
High-brightness fiber laser processing of high thermal conductivity material, it is best to use a small spot to maintain the stability of the welding hole, but this processing may make the process is too intense, resulting in a large number of welding splash. Experiments show that high-brightness red laser pointer with high-speed positioning of the remote scanning head, significantly reduce the welding splash, which is achieved by beam swing to ensure that the welding hole stability to achieve. Welding copper, aluminum, if you do not use the beam swing mode, welding splash will be very serious. Once the high-frequency swing beam is used, the splash will be reduced. By installing a protective device, to avoid damage to the equipment by the back light. Processing of copper and aluminum such high reflective metal, the return light is inevitable, the traditional laser due to the natural sensitivity of the return light, may lead to processing instability and destructive automatic shutdown, or even scrapped.
