Description
technical field [0001] The invention relates to the technical field of laser marking, in particular to a device and a marking method for improving the quality and efficiency of laser marking of materials. Background technique [0002] In recent years, with the improvement of the reliability and practicability of lasers, coupled with the rapid development of computer technology and the improvement of optical devices, the development of laser marking technology has been promoted. Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. In the laser marking method, the mask method and the scanning method are commonly used now. The scanning method is to use a computer to control the scanning galvanometer so that the highly focused laser beam moves and scans on the workpiece for marking. Laser marking usually uses th...
