Daily maintenance and precautions of laser engraving machine!

2020-06-15 18:09:02

The stable and normal operation of the machine is inseparable from the normal correct operation and daily maintenance. The following will introduce the daily maintenance of the laser engraving machine:

1. The replacement of water and the cleaning of the water tank (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 control the water temperature below 35℃. If it exceeds 35℃, it is necessary to change the circulating water or add ice cubes to the water to lower 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 inlet water pipe, let the water in the laser tube flow into the water tank automatically, 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 to the water tank, insert the water pipe connected to the water pump into the water inlet, and arrange the joints. Turn on the pump separately and run it for 2-3 minutes (fill the laser tube with circulating water).

2. Cleaning of the fan

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

3. Cleaning of the lens (it is recommended to clean before work every day, the equipment must be turned off)

In the introduction of the previous machine, it has been mentioned that there are 3 mirrors and 1 focusing mirror on the engraving machine (No. 1 mirror is located at the emission exit of the laser tube, that is, the upper left corner of the machine, and No. 2 mirror is located at the left end of the beam, The No. 3 reflector is located at the top of the fixed part of the laser head, and the focusing lens is located in the adjustable lens barrel at the lower part of the laser head.) The laser light is emitted from the laser head after being reflected and focused by these lenses. The lens is easy to get dust or other contaminants, causing laser loss or lens damage. Do not remove the No. 1 and No. 2 lenses when cleaning, just carefully wipe the lens cleaning paper dipped in the cleaning solution along the center of the lens. Rotate the edges to wipe. The No. 3 lens and the focusing lens need to be taken out of the frame and wiped in the same way. After wiping, they can be put back in the original form.

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

4. Cleaning of the guide rail (recommended to clean once every half a month, shutdown operation)

Guide rail and linear axis are one of the core components of the equipment. Its function is to guide and support. In order to ensure that the machine has higher processing accuracy, its guide rails and straight lines are required to have higher guiding accuracy and good motion stability. During the operation of the equipment, a large amount of corrosive dust and smoke will be generated during the processing of the processed parts. These smoke and dust will be deposited on the surface of the guide rail and linear shaft for a long time, which will have a great impact on the processing accuracy of the equipment and will Corrosion points are formed on the surface of the linear axis of the guide rail to shorten the service life of the equipment. In order to make the machine work normally and stably, and to ensure the processing quality of the products, the daily maintenance of the guide rails and linear axes should be carefully done.

Note: Please prepare for cleaning the rail-dry cotton cloth, lubricating oil

The guide rails of the engraving machine are divided into linear guide rails and roller guide rails. In the YM series, linear guide rails are used in the X direction and roller guide rails are used in the Y direction.

Clean the linear guide: first move the laser head to the far right (or left), find the linear guide as shown above, wipe with a dry cotton cloth until it is bright and dust-free, plus a little lubricating oil (sewing machine oil can be used to cut (Do not use motor oil), slowly push the laser head from side to side several times to distribute the lubricant evenly.

Cleaning the roller guide rail: Move the crossbeam to the inside, open the end covers on both sides of the machine, find the guide rail as shown above, wipe the place where the guide rails of the two sides and the roller touch with a dry cotton cloth, then move the crossbeam to clean the remaining place

5. Tightening of screws and couplings

After the motion system has been working for a period of time, the screws and couplings at the motion connection will be loose, which will affect the smoothness of the mechanical motion. Therefore, during the operation of the machine, observe whether there are abnormal noises or abnormal phenomena in the transmission components. Sturdy and maintenance. At the same time, the machine should tighten the screws one by one with a tool after a while. The first sturdiness should be about a month after the device is used.

6. Inspection of optical 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. There is no offset problem of the focusing mirror in the optical path, but the three mirrors are fixed by the mechanical part, and the possibility of offset is more Large, although there is no deviation under normal circumstances, it is recommended that users always check whether the optical path is normal before working.
