How to maintain the reflector of laser welding machine?
Customized Optical Components Supplier shares that laser welding machine belongs to 4 kinds of laser equipment, direct strong laser irradiation can cause serious damage to human skin, more serious is to blind the eyes, debugging operators must have laser safety protection of common sense, work must wear needle corresponding laser wavelength of special laser protection glasses. So today, changchun borida photoelectric and you to learn how to maintain the laser welding machine mirror and maintenance?
Changchun borida technology co., LTD. Is a professional engaged in various optical components, laser optical components, optical coating products. The main production of filters, reflectors, through infrared filters, half mirror, mirror, filter, color filter, splitter, infrared filters, narrow band filter, band pass filter, neutral density filter, optical coated glass, optical filter, optical glass, optical lenses, optical glass. Today we are going to learn about the maintenance of the reflector of laser welding machine.
Note: the adjustment of the laser must be done by specially trained personnel, otherwise the laser will be maladjusted or deviated, causing damage to other components in the optical path.
The adjustment steps of the laser resonator are as follows:
1. Check the reference light source
2. Adjust the position of the semi-mirror
3. Check the installation position of YAG rod
Artificial rotary reflection lens bracket, push the brake light to light blocking position, observe whether the red light in the center of the lens, the reflected light is located in the center of the beam end device on the absorption of the cone, such as the position is not right can be a little adjustment, finally, should pay special attention to carefully check whether the brake light reflection lens cleaning, contaminated the lens in use will soon burst. So far the laser part of the adjustment work is finished.
(1) in order to guarantee the normal work of the laser has been, for two weeks, or stop using for a period of time, in the first before starting the laser module, the medium diaphragm and protect glass lens and optical path components in check to determine the optical components without dust pollution, mildew and other anomalies, if you have the above phenomenon should be handled in time, ensure each optical component will not damage under strong laser irradiation. (the above inspection may be extended to one month or more if the equipment is used in a clean environment)
(2) equipment operators can often use black like paper to check the laser output spot. Once the spot is found to be uneven or the energy drops, the resonator of the laser should be adjusted in time to ensure the beam quality of the laser output.
(3) the purity of cooling water is the key to ensure the laser output efficiency and the service life of laser condenser chamber components. In use, the conductivity of internal circulating water should be checked once a week to ensure its conductivity is 30.5mw ·cm. The deionized water of internal circulation must be replaced once a month, and the conductivity of newly injected pure water must be 32MW·cm. Keep an eye on the color change of the ion exchange column in the cooling system. Once the color of the resin changes to dark brown or even black, the resin should be replaced immediately.
