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...

Abstract

The invention provides a multi-beam laser processing lens set and laser system capable of achieving spot energy distribution. The multi-beam laser processing mirror set and laser system comprises a lens cone assembly and a supporting and adjusting assembly. The lens cone assembly comprises n lens cones, and a collimating lens and a convergent lens are sequentially fixed into each lens cone in thebeam propagation direction. The supporting and adjusting assembly comprises a supporting assembly and an adjusting assembly. The supporting assembly comprises a center rod and a fixed ring, the centerrod is located in the axial center of the fixed ring, and the center rod is fixedly connected with the fixed ring through multiple supporting rods. The adjusting assembly comprises a sliding block and n connecting rods, and the sliding block can slide and be located along the center rod. One end of each of the n connecting rods is hinged to the side wall of the sliding block. The other ends of the connecting rods are hinged to the upper middle portions of the outer walls of the lens cones correspondingly. The fixed ring is hinged to the side wall of the lower portion of each lens cone. The problems that the laser spot size and energy distributed are hard to adjust and the adjusting cost is high are solved.

Description

technical field [0001] The invention relates to a multi-beam laser processing mirror group and a laser system capable of realizing the change of light spot energy distribution. Background technique [0002] The laser processing head is an important part of the laser processing system, which mainly includes an optical lens group and an atmosphere or a powder feeding device. The optical mirror group mainly completes the transmission of the laser beam from the fiber end face of the high-power fiber laser to the working plane, mainly including the collimating mirror part and the converging mirror part. The whole transmission process is generally a single beam transmission. The laser spot output by the traditional laser processing head with this structure is generally a solid spot, and the energy distribution of the laser spot can only be changed by changing the size of the laser beam acting on the working plane. [0003] The existing traditional laser processing head lens group...
