Doing a good job of daily cleaning of the laser marking machine can not only improve the processing effect of the product, but also extend the service life of the equipment.It saves costs while improving the work effect, which is indeed a wise move for general laser marking manufacturers. So what aspects should we do the daily cleaning of the laser marking machine?

1. Water replacement and water tank cleaning (it is recommended to clean the water tank and replace the circulating water once a week)

Note: Make sure that the laser tube is filled with circulating water before the machine works.

The quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water and keep the water temperature below 35°C. If it exceeds 35℃, the circulating water needs to be replaced, or ice cubes are added to the water to reduce the water temperature (it is recommended that the user choose a cooler or use two water tanks). Clean the water tank: first turn off the power, unplug the water inlet pipe, let the water in the laser tube automatically flow into the water tank, open the water tank, take out the water pump, and remove the dirt on the water pump. Clean the water tank, replace the circulating water, restore the water pump back to the water tank, insert the water pipe connected to the water pump into the water inlet, and arrange the connectors. Power on the water pump separately and run for 2-3 minutes (make the laser tube full of circulating water).

2. The cleaning of the lens (it is recommended to clean before work every day, and the equipment must be turned off)

In the previous machine introduction, it has been mentioned that there are 3 mirrors and 1 focusing mirror on the engraving machine. The No. 3 reflector is located on the top of the fixed part of the laser head, and the focusing mirror is located in the adjustable lens barrel at the lower part of the laser head. The laser is reflected and focused by these lenses and emitted from the laser head. The lens is easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. Do not remove the lens when cleaning the No. 1 and No. 2 lenses. Just place the lens wiping paper dipped in the cleaning solution carefully along the center of the lens. Rotating edge wipe. The No. 3 lens and focusing lens need to be taken out of the frame, wiped in the same way, and put back as they are after wiping.

Note: ①The lens should be wiped gently, and the surface coating should not be damaged; ②The wiping process should be handled gently to prevent it from falling; ③When installing the focusing lens, be sure to keep the concave surface down.

3. The cleaning of the fan

Long-term use of the fan will accumulate a lot of solid dust in the fan, causing the fan to produce a lot of noise, and it is not conducive to exhaust and deodorization. When the fan suction is insufficient and the smoke is not smooth, first turn off the power, remove the air inlet and outlet pipes on the fan, remove the dust inside, then turn the fan upside down, and pull the inner blades until they are clean , then install the fan.

4. The inspection of the optical path

The optical path system of the laser engraving machine is composed by the reflection of the mirror and the focusing of the focusing mirror. In the optical path, the focusing mirror has no offset problem, but the three mirrors are fixed by the mechanical part, and the possibility of offset is relatively high. Large, although there will be no offset under normal circumstances, it is recommended that the user check whether the optical path is normal before working.

At present, there are many series of fiber laser marking machine, semiconductor laser marking machine, CO2 laser marking machine, etc. Consumers should do the corresponding maintenance work according to the specific model during using so as to keep the equipment in a good job surroundings.
