specific Embodiment 1

[0024] A fiber laser processing head, such as figure 1 As shown, it includes sequentially setting a collimating integrator 200, a focusing integrator 300 and a first protective mirror 410 along the emission optical path of the laser beam 100. The laser beam 100 enters the collimating integrator 200 vertically and then enters the focusing integrator 300 horizontally. Then enter the first protective mirror 410 vertically, and the collimating integrator 200 and the focusing integrator 300 are both copper integrator mirrors. The fiber laser is the main equipment for generating the laser beam 100 for processing; the processing head is a beam shaping structure, which can shape the divergent laser beam 100 generated by the fiber laser into various light spots 700 to meet the processing needs. The processing head is matched with the fiber laser Used to meet the requirements of laser cladding on different sheets. The copper integrator is used for collimation and focusing. The copper i...

Abstract

The invention discloses a fiber laser processing head and a cladding plate process. The fiber laser processing head includes a collimating integrator mirror, a focusing integrator mirror and a first protective lens arranged sequentially along the laser beam emitting optical path, and the laser beam enters the collimating mirror vertically. After the integrating mirror, it enters the focusing integrating mirror horizontally, and then vertically enters the first protective lens. Both the collimating integrating mirror and the focusing integrating mirror are copper integrating mirrors. The cladding plate process includes cladding plate based on the process parameters of semiconductor direct output laser, using fiber laser to prepare cladding coatings of different shapes; comparing the cladding of fiber laser and semiconductor direct output laser cladding based on the same cladding process parameters Effect data; based on the comparison results, adjust the fiber laser cladding speed and cladding step to obtain the same cladding effect as the semiconductor direct output laser. The invention improves the service life of the fiber laser and ensures the cladding effect of the fiber laser.

Description

technical field [0001] The invention belongs to the technical field of laser cladding, and in particular relates to a fiber laser processing head and a cladding plate process. Background technique [0002] The collimation structure and focusing structure of the semiconductor direct output laser are integrated inside the laser, which belongs to the transmission type. The rear of the collimation structure is the core component of the laser. In the process of plate cladding, the reflected laser beam will act on the surface of the laser stack through the focusing system and the collimation system. When the energy accumulation is too large, the core components of the laser will be burned out, resulting in the failure of the laser. [0003] Therefore, the existing technology still needs to be further developed and improved. SUMMARY OF THE INVENTION [0004] In view of various deficiencies of the prior art, in order to solve the above problems, a fiber laser processing head and ...
