Problems solved by technology

During the plate cladding process, the reflected laser beam will act on the surface of the laser array through the focusing system and collimation system. When the energy accumulation is too large, it will burn out the core components of the laser, resulting in laser failure

Abstract

The invention discloses an optical fiber laser processing head and a plate cladding process. The optical fiber laser processing head comprises a collimation integral mirror, a focusing integral mirror and a first protection lens which are sequentially arranged along a laser beam emission light path, a laser beam vertically enters the collimation integral mirror, then horizontally enters the focusing integral mirror, and then vertically enters the first protection lens. The collimation integral mirror and the focusing integral mirror are both copper integral mirrors. The plate cladding process comprises the following steps: directly outputting process parameters of a laser cladding plate based on a semiconductor, and preparing cladding coatings with different shapes by adopting an optical fiber laser; comparing cladding effect data obtained by cladding of the optical fiber laser and a semiconductor direct output laser based on the same cladding process parameters; and adjusting the cladding speed and the cladding step pitch of the optical fiber laser based on the comparison result, so that the cladding effect the same as that of the semiconductor direct output laser is obtained. The service life of the optical fiber laser is prolonged, and the cladding effect of the fiber laser is guaranteed.

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 cladding plate technology. 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, and the back of the collimation structure is the core component of the laser, the light-emitting array. During the plate cladding process, the reflected laser beam will act on the surface of the laser stack through the focusing system and collimation system. When the energy accumulation is too large, the core components of the laser will be burned out, resulting in laser failure. [0003] Therefore, prior art still needs further development and improvement. Contents of the invention [0004] Aiming at the deficiencies of the existing technology, in order to solve the above problems, a fiber laser processing h...
