Background
The laser marking machine is to irradiate the surface of different workpieces with high energy density laser beam to vaporize the surface material of the material or change its color, so as to expose the deep material or to burn out the surface material to show the etched pattern or character. More specifically, the laser marking machine is mainly applied to occasions requiring more fineness and higher precision, such as electronic components, integrated circuits, mobile phone communication, hardware products, tool accessories, precision instruments, glasses, clocks, jewelry, automobile accessories, building materials and the like.
Existing laser marking machines typically include a laser, a focusing lens, and a galvanometer cavity.
