Abstract: A laser processing device includes a laser source, a zoom assembly for converging a laser light emitted by the laser source, a scanning galvanometer assembly for receiving the converged laser light exiting from the zoom assembly and emitting the laser light at a preset angle, and a reflection assembly arranged between the scanning galvanometer assembly and a workpiece. The zoom assembly includes a plurality of lens groups, the reflection assembly includes a plurality of reflectors for reflecting the laser light emitted by the scanning galvanometer assembly to the workpiece. A distance between any two lens groups of the plurality of lens groups is adjustable to adjust a position of a principle plane of the zoom assembly, thereby adjusting a focus position reflected to the workpiece.
