[0002] Laser coding machine refers to printing text or pattern information on the surface of the product in the form of laser marking. The laser is concentrated on the surface of the object to be marked with extremely high energy, and the material on the surface is vaporized through burning and etching. By controlling the effective displacement of the laser beam, the pattern or text, such as the production date, batch number, serial number, model, etc. of the product, can be accurately engraved. According to the different identification forms of the laser coding machine, laser coding equipment can be divided into two types: engraving type and dot matrix type. Most of the laser printing equipment currently on the market is engraving type. The scribing laser machine mainly engraves the trajectory points of the characters to be marked completely, which can be distinguished by the naked eye without the aid of any auxiliary tools, which is convenient for consumers to identify. Laser printers have broken through the standardization and singleness of traditional ink jet coding technology, creating a new coding method and enhancing the competitiveness of products in the increasingly fierce market.
