Laser marking machine technology is one of the largest application fields of laser processing. Laser marking, as a new high-tech marking method, is a marking method that uses high-energy density laser to locally irradiate the workpiece to make the surface material evaporate or change color, thus leaving a permanent mark. Laser marking can produce various characters, symbols and patterns. The size of characters can range from millimeter to micron, which has special significance for product anti-counterfeiting. Compared with traditional marking methods such as mold, electro etching marking, self-adhesive, screen printing, startup marking, etc., It has the characteristics of fast processing speed, high precision and no fading. At the same time, laser marking is a non-contact processing process, which has no mechanical effect and will not damage the materials on the surface of the processed object.
So now, in order to ensure the marking effect of parts, automobile manufacturers widely use lasers to mark part information. In addition, the laser equipment adopts computer software control system, which has strong compileability and stable performance. It can not only edit the pattern and text of auto parts, but also meet the current needs of mass production and personalized customization, and provide more manufacturing space for the current automotive design and manufacturing.
At present, people pay more and more attention to safety while paying attention to the performance of vehicles. Auto parts belong to multi variety and large-scale production. At present, the quality control mainly adopts spot check, which belongs to back test and cannot play a preventive and control role in the production process. Now, through information tracking, we can turn the post inspection of quality control into pre prevention, and laser marking plays an important role in this link. By using the information of laser marking parts and online monitoring, abnormal parts can be found and eliminated in time to prevent defective products in production and check product quality.
Moreover, for those defective products that cannot be detected in production, we can trace the information through the information marked on the parts, so as to quickly determine the cause and batch of defects and make rapid response in time. This not only effectively improves the quality of auto parts, but also ensures the driving safety of the car, gives every car passenger more protection, and avoids some accidents caused by small faults.
In the field of auto parts processing, the laser marking machine is mainly used to mark information such as two-dimensional code, bar code, clear code, production date, serial number, logo, pattern, certification mark, warning mark, etc. It includes high-quality identification of automobile wheel arc, exhaust pipe, engine block, piston, crankshaft, sound transmission button, label (nameplate) and other accessories.
