The laser marking can print various characters, symbols, patterns and the like, and the size of the characters can be from millimeter to micron, which has special significance for the anti-counterfeiting of products. The laser of the fiber laser marking machine uses rare earth element doped glass fiber as a gain medium, is a new generation product of the marking machine, and has the marking effect that deep substances are exposed through the evaporation of surface substances, or the physical change of the surface substances is caused by light energy to mark, or partial substances are burnt through the light energy, so that the laser has the cutting and removing effect on materials.

When the fiber laser marking machine marks the surface of the material, focusing is needed, and marking can be successfully carried out only at the accurate focal position. When materials with different thicknesses are marked, the position of a laser outlet needs to be adjusted to the focal length which is just right positioned on the upper surface of the material, while the existing optical fiber laser marking machine is either fixed or automatically adjusted after ranging by a ranging sensor, and the latter has higher cost when meeting the requirement of simple marking in discontinuous production.
