How To Maintain?

In order for the machine to work smoothly, the daily maintenance is indispensable. As long as the parts are not damaged, we can maintain it by ourselves. Here are some tips for care and maintenance.

Components that require daily maintenance: vibrating mirrors, lasers, power lines, and lifting guide rails.

1. The first is the galvanometer. There are two motors in the vibrating mirror that control the laser circuit, one is in the direction of the x-axis and the other is in the direction of the y-axis. There are magnetic components in the motor, and there are two lenses that cooperate with the motor to reflect the laser. Therefore, the vibrating mirror needs to be kept away from strong magnetism, strong Electricity, strong shock current items, avoid touching the galvanometer with hands and items. If the lens is dusty, you can use a rag and a small amount of alcohol to clean it, and wipe it in one direction.

2. The laser generates light beams, so it needs to dissipate heat. Regularly clean the dust. Use an air gun to blow along the direction of the air duct. At the same time, clean the relevant circuit boards to avoid burning out due to poor heat dissipation of the machine. The air gun is a good tool and can also clean the laser with cold water. machine.

3. Check whether the grounding of the equipment is reliable, and the power cord and plug are intact to avoid leakage accidents.

4. The guide rail for adjusting the focus of the machine is often used, so it is necessary to add lubricating oil and do a good job of sanitation once a month to avoid guide rail jamming and inaccurate focus. Regularly check whether the equipment fan is normal. The fan is used to dissipate heat. To ensure smooth rotation.

In addition, it is necessary to develop good usage habits when using the machine. Before use, check whether the software settings have changed, and whether the function buttons and indicators are normal. After use, clean the surface of the workbench, monitor, and keyboard with a clean rag, and remove the garbage in time, especially the residue or powder after marking, clean the surrounding sanitation, and keep it ventilated.

Note: When shutting down, please turn off the laser power first and then close the marking software, otherwise it will damage the life of the laser.

If the machine uses water-cooling equipment, it is necessary to replace the circulating water and clean the water tank. Clean it once a week and replace the water inside. If the circulating water inside is too long, it is not good for the machine. The water quality and temperature of the circulating water will directly affect the service life of the laser tube. It is recommended to use pure water or distilled water, and keep the water temperature below 35°C.
