Problems solved by technology

The disadvantage is that since the high-speed scanning galvanometer device is not used, the processing speed is only determined by the mechanical movement speed of the robot, and the high-efficiency advantages of high-speed deflection and scanning processing of the laser galvanometer are not brought into play.

[0005] At present, the three-dimensional complex surface laser etching processing scheme based on galvanometer scanning is limited to the combination of a single laser galvanometer scanning processing head and multi-axis CNC machine tools or industrial robots for complex surface scanning and etching processing. The reason is that the hardware structure of the system is complex. , involving multi-interdisciplinary technologies such as opto-mechanical and electrical software, space motion combining multi-axis mechanical motion and optical scanning motion, and CAM software design and development are difficult, etc. The current system still has the problem of long processing time and low efficiency when processing large three-dimensional parts. question
