In this embodiment, reference may also be made to the above-mentioned embodiments, namely:

setting the linear distance from the outlet of the laser module 100 to the inlet of the adjustment module 300 as L _A The linear distance from the exit of the adjustment module 300 to the entrance of the reflection module 200 is L _B The linear distance from the exit of the reflection module 200 to the entrance of the processing module 400 is L _C The laser transmission distance from the exit of the processing module 400 to the processing plane 500 is L _D The method comprises the steps of carrying out a first treatment on the surface of the The total transmission distance from the laser module 100 to the outside of the processing plane 500 through the adjusting module 300, the reflecting module 200 and the processing module 400 after the laser is emitted is L _A +L _B +L _C +L _D In the present embodiment, the distance L _A Distance L _B Distance L _C Are all adjustable;

therefore, in the present embodiment, if the total transmission distance L between the front and rear two times is to be ensured _A +L _B +L _C +L _D Distance L, if kept the same _A Distance L _B Then need to be according to L _C Is appropriately adjusted, i.e. the distance L _C When decreasing or increasing, i.e. distance L _A And distance L _B The sum is increased or decreased accordingly to make the total transmission distance L of the two times _A +L _B +L _C +L _D Keeping the consistency;
