Abstract

The embodiment of the invention relates to a laser marking machine and a marking method thereof. The laser marking machine comprises an electrical control part, a laser device, a beam expander, a galvanometer system, an optical focusing lens and a working platform. The electrical control part provides energy power for the laser device and controls the laser device to transmit lasers. The lasers transmitted by the laser device are amplified through beam expansion to shoot into the galvanometer system, the amplified lasers shoot onto the optic focusing lens after being deflected through the galvanometer system, and the lasers irradiate the surface of a workpiece put on the working platform for marking after being focused by the optic focusing lens. According to the laser marking machine and the marking method thereof, anodic oxidation treatment does not need to be carried out on an aluminum alloy material, the lasers penetrate a transparent adhesive tape film, a laser beam acts on the surface of an aluminum alloy, permanent marking is achieved, cost is low, and pollution is avoided.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of laser processing, and in particular relate to a laser marking machine and a marking method thereof. Background technique [0002] The existing laser marking process on the surface of aluminum alloy is usually marked in white or dark gray, and the aluminum alloy material itself is silvery white, so the content of laser marking and the substrate cannot form a sharp contrast effect. [0003] If it is necessary to carry out laser blackening process on the surface of aluminum alloy, the aluminum alloy material must be anodized first to form an anodized film, and then the laser is used to mark the surface of the anodized layer of aluminum alloy to mark it black, forming a sharp contrast Effect. However, the above-mentioned processing method needs to perform anodic oxidation treatment on the aluminum alloy material, which increases a large amount of industrial production costs. Conte...
