In the daily work, if the laser marking machine is not maintained, the laser marking machine will easily cause problems such as rust or depreciation and damage caused by other reasons. Therefore, in order to avoid these problems, we need to correct the problems. Laser marking machine for maintenance. Maintenance of the laser marking machine can be roughly performed from the following five aspects. The laser beam of the laser marking machine can produce physical or chemical changes on the surface of the material, so as to obtain the required pattern or text. It can be used as a security mark and can also improve the beautification effect and artistic quality of the product. However, in the process of using a laser marking machine , the maintenance of the laser marking machine is very important. So how to maintain the laser marking machine in the end?
First, lens cleaning
There are 3 reflectors and 1 focusing mirror on the engraving machine (No. 1 reflector is located at the exit of the laser tube, which is the upper left corner of the machine, No. 2 reflector is located at the left end of the beam, and No. 3 reflector is located at the fixed part of the laser head The focusing lens is located in the adjustable lens barrel at the bottom of the laser head). The laser light is reflected and focused by these lenses and emitted from the laser head. The lens is easily contaminated with dust or other pollutants, causing laser loss or lens damage. Do not remove the 1st and 2nd lenses when cleaning, just carefully wipe the lens cleaning paper dipped in the cleaning solution toward the center of the lens. Edge swivel wipe. The No. 3 lens and focusing lens need to be removed from the frame and wiped with the same method. After wiping, replace them as they are. (It is recommended to clean before work every day, the equipment must be turned off)
Second, the replacement of water and the cleaning of the water tank
Clean the water tank and replace the circulating water once a week. The water quality and temperature of the circulating water directly affect the life of the laser tube. It is recommended to use pure water and control the water temperature below 35 ° C. If the temperature exceeds 35 ℃, the circulating water needs to be replaced, or ice cubes can be added to the water to reduce the water temperature. (It is recommended that users choose a cooler or use two water tanks)
Cleaning the water tank: first turn off the power, unplug the water inlet pipe, and let the water in the laser tube automatically flow into the water tank. Clean the water tank, replace the circulating water, return the water pump to the water tank, insert the water pipe connected to the water pump into the water inlet, and arrange the joints. Power on the pump separately and run for 2-3 minutes (make the laser tube full of circulating water)
Inspection of the light path
The optical path system of the laser engraving machine is completed by the reflection of the reflecting mirror and the focusing of the focusing mirror. There is no offset problem in the focusing lens in the optical path, but the three reflecting mirrors are fixed by mechanical parts. Large, although it usually does not shift, but it is recommended that users check whether the optical path is normal before each work.
4. Fastening of screws and couplings
After the motion system works for a period of time, the screws and couplings at the motion joints will loosen, which will affect the smoothness of the mechanical movement. Therefore, during the operation of the machine, observe whether there are abnormal noises or abnormal phenomena in the transmission parts, and find the problems in time. Robust and maintenance. At the same time, the machine should use a tool to tighten the screws one by one after a period of time. The first solidification should be about one month after the equipment is used.
Five, fan cleaning
Long-term use of the fan will cause a lot of solid dust to accumulate in the fan, which will cause a lot of noise and is not conducive to exhaust and deodorization. When the suction power of the fan is insufficient and the smoke is not smooth, first turn off the power, remove the air inlet and outlet pipes from the fan, remove the dust inside, and then turn the fan upside down and pull the air blades inside until it is clean , And then install the fan.
