Laser output head and laser machining machine

Abstract

The invention discloses a laser output head and a laser machining machine. The laser output head comprises a first laser output unit, a second laser output unit, a first beam combining unit and a focusing unit, wherein the first laser output unit is used for outputting a first laser beam, the second laser output unit is used for outputting a second laser beam, the first beam combining unit is positioned in front of laser output ports of the first laser output unit and the second laser output unit and used for converting the first laser beam and the second laser beam into laser beams in one output direction, and the focusing unit is adjacent to the first beam combining unit and used for focusing the laser beams outputted by the first beam combining unit to form a focused beam. One laser output head can output the laser beams with different wavelengths , for example, the laser machining machine is compatible with QCS (quality control system) connection joint, a QBH (query by humming) connection joint and a pulse connection joint, and different materials are cut, welded or marked without replacing output connectors.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a laser output head and a laser processing machine. Background technique [0002] Due to its advantages of good monochromaticity, small divergence and high brightness, laser is widely used in the field of mechanical processing, such as laser cutting, welding, laser marking and so on. [0003] In the prior art, each laser uses a different form of laser output head. A laser processing machine is equipped with only one laser output head, which outputs laser light of one wavelength and completes a specific process. It cannot be compatible with multiple laser processing machines. For example, the cutting machine can only complete cutting, the marking machine can only complete marking, etc., but because different materials absorb different wavelengths of laser light differently, when it is necessary to use laser output heads from different manufacturers to complete For different proces...

[0003] In the prior art, each laser uses a different form of laser output head. A laser processing machine is equipped with only one laser output head, which outputs laser light of one wavelength and completes a specific process. It cannot be compatible with multiple laser processing machines. For example, the cutting machine can only complete cutting, the marking machine can only complete marking, etc., but because different materials absorb different wavelengths of laser light differently, when it is necessary to use laser output heads from different manufacturers to complete For different processes, it is necessary to dismantle the entire equipment, which is particularly troublesome. For example, if you want to complete the cutting and welding processes on the marking machine, you need to disassemble the entire marking machine and replace the laser output head. If you want to complete the cutting and welding processes on the cutting machine The marking process also needs to disassemble the entire cutting machine, and it is troublesome to replace the laser output head
