Problems solved by technology

[0003] However, due to processing and assembly errors in the existing laser processing head, the incident point of the laser will deviate from the central optical axis of the copper mirror, resulting in poor roundness of the focused spot, which is not conducive to improving the processing quality.

Abstract

The invention discloses a laser processing head, and belongs to the technical field of laser processing. The laser processing head comprises an optical fiber interface, a first protection device, a collimation device, a focusing device, a second protection device and a nozzle device which are sequentially arranged from one end to the other end, and further comprises a first adjusting device, wherein one end of the first adjusting device is connected to the optical fiber interface, the other end of the first adjusting device is connected to the first protection device, and the first adjusting device can drive the optical fiber interface to move in the first direction perpendicular to the incident direction of a laser beam and the second direction perpendicular to the incident direction of the laser beam and the first direction at the same time. According to the laser processing head, the position of a laser incident point can be adjusted, the deviation between the incident point of the laser and the central optical axis of the collimation device is reduced, then the shape of a light spot output from the nozzle device is adjusted, the quality of the laser beam is improved, and the processing quality is improved.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser processing head. Background technique [0002] There are two types of laser processing heads: transmissive and reflective. The reflective lens is generally made of copper. Copper has good thermal conductivity and stable performance. Compared with the transmissive quartz lens, it is more stable, not easy to burn out, and easier to withstand high power. At present, the laser industry is developing in the direction of high power, so reflective laser processing heads are more and more widely used. [0003] However, due to processing and assembly errors in the existing laser processing head, the incident point of the laser will deviate from the central optical axis of the copper mirror, resulting in poor roundness of the focused spot, which is not conducive to improving the processing quality. Contents of the invention [0004] The object of the present invention i...
