With the continuous improvement of people’s living standards, people’s demand for cars is also increasing. At the same time, people pay more and more attention to the performance and after-sales maintenance of cars. Facing opportunities and challenges, many automobile manufacturers have to seek breakthroughs in manufacturing.
Laser marking machine technology is one of the largest application fields of laser processing. As a high-tech marking means, laser marking is a marking method that uses high-energy density laser to locally irradiate the workpiece to vaporize the surface material or produce a chemical reaction of color change, so as to leave a permanent mark. Laser marking can print all kinds of characters, symbols and patterns, and the character size can range from millimeter to micron, which is of special significance to the anti-counterfeiting of products. Compared with the traditional marking methods such as mold, electric corrosion marking, self-adhesive, screen printing and start-up marking, it has the characteristics of fast processing speed, high precision and indelible; At the same time, laser marking belongs to a non-contact processing process. In the processing process, there is no mechanical effect and will not damage the materials on the surface of processed items. Therefore, in order to ensure the marking effect of parts, automobile manufacturers now widely use laser to mark the information of parts. Moreover, the laser equipment adopts the computer software control system, which has strong compileability and stable performance. It can not only edit the pattern and text of automobile parts, but also meet the current mass production needs and personalized customization needs, providing more manufacturing space for the current automobile design and manufacturing.
At present, while people pay attention to the performance of vehicles, they also have increasing concerns about safety. Auto parts belong to multi variety and large-scale production. At present, the quality control mainly adopts the way of sampling inspection, which belongs to post inspection, and can not play the role of prevention and control in the production process. Now, through information tracing, we can change the quality control from post inspection to pre prevention. Laser marking plays an important role in this link. Using the information of laser marked parts, we can find and eliminate abnormal parts in time through online monitoring, prevent defective products in production and inspect 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, laser marking machine is mainly used to mark two-dimensional code, bar code, clear code, production date, serial number, logo, pattern, certification mark, warning mark and other information. Including high-quality marking of automobile wheel arc, exhaust pipe, engine cylinder block, piston, crankshaft, sound transparent key, label (nameplate) and other accessories.
