In terms of automobile marking, although there are several types of mold casting, electrocorrosive marking, self-adhesive, screen printing, pneumatic marking and laser marking on the market, laser marking technology is the latest, but the laser marking is traditional. The advantages unmatched by processing methods are gradually being recognized by more and more car manufacturers.
In the current automotive industry, we can see the laser application everywhere. It can be said that the current laser technology is ubiquitous to change the current automobile manufacturing industry. At present, laser technology has laser marking, hardening, cutting, welding, etc. in the automotive field. Each process has different processing characteristics from the traditional process, and the current automobile manufacturing industry is obtained in terms of process and quality. Upgrade.
Application of laser marking technology in two-dimensional code automobile manufacturing industry
In recent years, with the introduction of national laws and regulations on automobile safety, high requirements have been placed on the uniqueness of automobiles and parts. The establishment of the identity of automobiles and parts is the basis for realizing product quality traceability and recall. Because laser processing is different from traditional processing methods, laser processing is a marking method that uses a high-energy-density laser to locally irradiate a workpiece to vaporize the surface material or cause a chemical reaction of color change, thereby leaving a permanent mark. No need to touch the surface of the processed article, so any shaped surface material can be marked and the workpiece will not deform and generate internal stress. At the same time, laser processing is a fast, programmable process. The process is long-lasting, usually not affected by the steps required in the production process, and is not affected by the harsh site environment, and the marking is wear-resistant, and the production process is easy to automate. This is undoubtedly the best marking processing solution for the automotive industry that pursues efficiency and quality.
At present, the application of laser marking machine in automobile applications includes automobile parts, engine, label paper (flexible label), etc. Among them, laser bar code and two-dimensional code are often used for traceability of automobile parts, which not only satisfies the recall system of vehicle defects. Requirements, but also the acquisition of parts information and quality traceability, which has important special significance for the current automotive industry.
