Maintenance knowledge of laser reflector
Laser welding machines belong to the fourth category of laser equipment. Direct exposure to strong laser radiation can cause serious harm to human skin and even blindness. Therefore, debugging personnel must have knowledge of laser safety protection and wear specialized laser protective glasses with corresponding laser wavelengths. Today, Ruicheng Optoelectronics will explain how to maintain and care for laser welding machine reflectors.
Note: Laser adjustment must be carried out by specially trained personnel, otherwise other components on the optical path may be damaged due to laser offset or misalignment.
The adjustment steps for laser resonators include the following three aspects:
1. Check the reference light source
2. Adjust the position of the half mirror
3. Adjust the installation position of YAG fiber rod
Manually rotate the mirror bracket, push the shutter to the light blocking position, and observe whether the red light is in the middle of the lens and whether the reflected light is on the absorption cone at the center of the beam terminator. If the position is incorrect, adjust it slightly. Finally, special attention should be paid to carefully checking whether the shutter mirror is clean, as contaminated lenses can quickly crack during use. Laser segment adjustment completed.
To ensure that the laser is always in normal working condition, after running continuously for two weeks or after the laser is stopped for a period of time, the components in the optical path, such as the laser module, medium aperture, lens protective glass, etc., should be checked before starting up to ensure that each component is free of dust pollution, mold and other abnormal phenomena. If the above phenomenon occurs, it should be dealt with in a timely manner to ensure that the optical components are not damaged by strong laser irradiation.
Operators can use black image paper to check the laser output spot. When the spot is uneven or the energy decreases, the laser resonant cavity should be adjusted in a timely manner to ensure the quality of the laser output beam.
The purity of cooling water is the key to ensuring the efficiency of laser output and the service life of laser focusing cavity. The conductivity of newly injected pure water must be 32 mW; cm， Once the resin color in the exchange column turns dark brown or even black, replace the resin immediately.
