1, The cleaning of the exhaust fan of the laser machine
The long-term use of the exhaust fan will cause a lot of solid dust to accumulate inside the fan, which will cause a lot of noise and is not conducive to exhaust and deodorization. When the suction of the exhaust fan is insufficient and the exhaust effect is not good, first turn off the power supply, remove the air inlet pipe and the air outlet pipe on the exhaust fan, remove the dust inside, then tilt the fan upside down and pull the fan blades inside. Until it is clean, then install the blower.
2, The replacement of water and the cleaning of the water tank (recommended to clean the water tank and replace the circulating water once a week)
Cleaning the water tank: first, turn off the power supply, 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, put the water pump back into the water tank, insert the water pipe connected to the water pump into the water inlet, and arrange the joints. Power the pump separately and run for 2-3 minutes (fill the laser tube with circulating water).
Note: The laser tube must be filled with circulating water before working.
The water quality and water temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 35 °C. If it exceeds 35 °C, it is necessary to replace the circulating water or add ice cubes to the water to lower the water temperature (user is recommended to choose a cooling machine).
3, The lens cleaning (recommended to clean before work every day, the equipment must be turned off)
There are 3 mirrors and 1 focusing mirror on the laser cutting machine (the No. 1 mirror is located at the emission exit of the laser tube, which is the upper left corner of the machine, the No. 2 mirror is located at the left end of the beam, and the No. 3 mirror is located at the laser head. At the top of the part, the focusing mirror is located in an adjustable barrel in the lower part of the laser head. The laser is reflected by these lenses, focused and emitted from the laser head. The lens is easily stained with dust or other contaminants, causing laser loss or lens damage. Do not remove the No. 1 and No. 2 lenses. Just wipe the lens with the cleaning solution carefully along the center of the lens. Edge rotary wipe. The No. 3 lens and the focusing mirror need to be taken out from the frame and wiped in the same way. After the wiping is completed, it can be put back as it is.
1 The lens should be wiped gently, and the surface coating should not be damaged;
2 The wiping process should be handled gently to prevent falling;
3 Be sure to keep the concave side facing down when installing the focusing mirror.
4, An inspection of the light path
The optical path system of the laser engraving machine is completed by the reflection of the mirror and the focusing of the focusing mirror. In the optical path, there is no offset problem in the focusing mirror, but the three mirrors are fixed by the mechanical part, and the possibility of offset is higher. Large, although the offset does not usually occur, it is recommended that the user check whether the light path is normal before each work.
5. Fastening of screws and couplings
After the motion system is working for a period of time, the screws and couplings at the joint of the movement will be loose, which will affect the smoothness of the mechanical movement. Therefore, in the operation of the machine, it is necessary to observe whether the transmission parts have abnormal noise or abnormal phenomena. Rugged and maintenance. At the same time, the machine should use a tool to tighten the screws one by one. The first time it should be sturdy about a month after the device is used.
6, Cleaning of the guide rails Suggestion
Clean once every half month, shut down the operation. The guide rail and linear shaft are one of the core components of the laser cutting machine. Its function is to guide and support. In order to ensure the machine has high machining accuracy, the guide rail and straight line are required to have high guiding precision and good motion stability. During the operation of the equipment, due to a large amount of corrosive dust and smoke generated during processing, the smoke and dust are deposited on the surface of the guide rail and the linear shaft for a long time, which has a great influence on the processing precision of the equipment. An etch point is formed on the surface of the linear axis of the guide rail to shorten the service life of the device. In order to make the machine work stably and ensure the quality of the products, it is necessary to carefully carry out the daily maintenance of the guide rails and linear axes.
Note: Please prepare the cleaning rails – dry cotton cloth, lubricating oil (car use level).
Cleaning the linear guide: first, move the laser head to the far right (or left side), wipe it with a dry cotton cloth until it is bright and dust-free, add a little lubricant, and slowly push the laser head a few times to make the lubricant even. Distribution can be.
Cleaning the roller guide: Move the beam to the inside, open the end cover on both sides of the machine, wipe the place where the guide rails are in contact with the roller with a dry cotton cloth, and then move the beam to clean the remaining place.
