How to maintain the plastic laser welding machine?

Laser welding machines have become standard equipment for some high-end industrial production and processing companies, with automatic welding skills as a strategic goal. How to maintain the laser welding machine during the application process? The maintenance of the laser welding machine must be carried out by professionals with systematic training.

Purity is the key to ensuring the output power of the laser and the service life of the laser focusing cavity components. Check the conductivity of the inner circulating water once a week to ensure its conductivity. The inner circulating deionized water needs to be replaced once a month. Investigate the color changes of the ion exchange column in the cooling system at any time. Once the color of the resin in the exchange column turns dark brown or even black, the resin should be replaced immediately.

Equipment operators can often check the laser output light spot with black image paper. Once it is found that the light spot is uneven or the energy is reduced, the laser resonant cavity should be adjusted in time to ensure the quality of the laser output beam. The debugging operator must have laser safety protection knowledge and must wear special laser protection glasses during operation. The adjustment of the laser must be performed by specially trained personnel, otherwise other components in the optical path will be damaged due to the imbalance or deviation of the laser.

To ensure that the laser welding machine laser is always in normal operation, after continuous operation or stopping use for a period of time, the YAG rod, dielectric film, lens maintenance glass and other optical path components should be checked to confirm that the optical components are not contaminated. If there is contamination, it should be handled in time to ensure that the optical components are not damaged.
