By controlling the first driving mechanism 300, the second driving mechanism 400, and the third driving mechanism 500 to move and rotate the object to be processed, the laser beam 202 is always perpendicular to the surface of the object during the laser surface treatment. The desired processing effect can be obtained, for example, when laser engraving on different surfaces, the patterns at the interface of different surfaces can be maintained continuously without the occurrence of disconnection or splicing marks.

Based on the design of the laser surface treatment device 100 disclosed in this disclosure, when performing laser surface treatment on different surfaces of an object, there is no need to interrupt the processing process to additionally set a jig corresponding to the shape of the object (for example, use the jig to adjust the object to be processed) The surface makes the laser beam 202 perpendicular to the surface to be processed), so not only the steps of laser surface processing can be reduced, but also the overall processing time can be shortened. Furthermore, the laser transmitter 200 may be provided with a plurality of lens modules, which can further adjust the laser. The advancing direction of the light beam 202 and its focal position can further shorten the laser surface treatment time, and can further improve the effect of the laser surface treatment.
