Partial illumination of the workpiece with a high energy density laser causes the surface material to vaporize or undergo a chemical reaction of color change, leaving a permanent mark. Laser marking can mark a variety of text, symbols and patterns, and the size of the characters can even reach the order of micrometers. The laser beam used for laser marking is generated by a laser, and after a series of optical conduction and processing, the beam is finally focused by the optical lens, and then the focused high-energy beam is deflected to a specified position on the surface of the object to be processed to form a permanent recess. trace. Conventional 2D laser marking uses a post-focusing method, and generally only performs planar marking within a specified range. The advent of the new 3D laser marking machine solves the long-standing defect of the 2D laser marking machine. The 3D laser marking machine adopts the advanced front gathering method, and the dynamic focusing seat is added. This takes the optical principle, like the image. The working principle of candle imaging, through software control and moving dynamic focusing mirror, can be expanded and expanded before the laser is focused, so as to change the focal length of the laser beam to achieve accurate surface focusing processing of high and low objects.
