Maintenance and Precautions for Robot Laser Welding Machine

In order to ensure that the laser is always in normal working condition, the robot laser welding machine should first inspect the components in the optical path such as YAG rod, dielectric film, and lens protective glass before starting up after two weeks of continuous operation or after a period of application. It is necessary to confirm that each optical component is free of dust pollution, mold, and other abnormal phenomena. If any of the above phenomena occur, they should be dealt with in a timely manner to ensure that each optical component will not be damaged under strong laser irradiation. If the application environment of the equipment is relatively clean, the above inspection can be extended to a month or even longer accordingly

The purity of cooling water is the key to ensuring laser output efficiency and the lifespan of laser focusing cavity components. In applications, the conductivity of the circulating water should be checked once a week to ensure its conductivity is 30. 5MW•cm， The deionized water for internal circulation must be changed once a month, and the conductivity of the newly injected pure water must be 32MW • cm. Always pay attention to the color changes of the ion replacement column in the cooling system. Once the color of the resin in the replacement column changes to dark brown or even black, the resin should be replaced immediately.

Equipment operators can often use black paper to check the laser output spot. Once uneven spots or energy drops are found, the resonant cavity of the laser should be adjusted in a timely manner to ensure the quality of the laser output beam. The typical spot image is as follows: Adjustment of the laser resonant cavity for the spot that has been adjusted but not yet adjusted

Reminder: This product belongs to Class 4 laser equipment. Direct strong laser irradiation can cause serious and minor damage to human skin, especially blindness. Debugging operators must have knowledge of laser safety protection and wear specialized laser protective glasses for 064mm wavelength during work.
