Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0032] The present invention can make more than three collimated and converged single-mode fiber laser lasers converge to the same point or form a hollow spot circle around a point through the multi-beam laser processing mirror group, and the size of the aperture can be adjusted according to the adjustment device Make changes.
[0033] The specific structure of the multi-beam laser processing mirror group is as follows: figure 1 As shown, including lens barrel assembly and support adjustment assembly.
[0034] In this embodiment, the lens barrel assembly includes five lens barrels 3; a collimating lens and a converging lens are fixed inside each lens barrel 3, and the collimating lens and the converging lens are sequentially arranged along the incident direction of the light beam. The upper end of the lens barrel 3 can be connected to the las...
