Six tips for maintaining laser marking machines

by:Leadtech Coding     2022-03-09

Everyone knows that the laser marking machine can lay down its brand information, which helps to promote the brand, and can also prevent counterfeiting and prevent some unscrupulous traders from damaging our brand reputation. However, if the laser marking machine is not well maintained, it will not only fail to play the role of anti-counterfeiting, but also make it easier for customers to think that it is a product of poor quality.

One: Fan cleaning

Long-term use of the fan will cause a lot of solid dust to accumulate in the fan, which will make the fan make a lot of noise, and is not conducive to exhaust and deodorization. The solution is to first turn off the power, remove the air inlet and outlet ducts on the fan, remove the dust inside, then turn the fan upside down, and pull the fan blades inside until it is clean, and then install the fan. Friendly reminder: the removed parts should be carefully protected, and the screws should be carefully preserved.

Second: Fastening of screws and couplings

After the motion system works for a period of time, The screws at the moving joints will be loose. If they are not tightened in time, the screws will become loose and affect the stability of the machine. It may also cause the screws to fly out directly, and a certain part of the machine will be scattered directly, and the machine will eventually collapse. . Therefore, during the operation of the machine, it is necessary to observe whether there is any abnormal noise or abnormal phenomenon in the transmission parts. If the problem is found, it must be strengthened and maintained in time. It is a bit troublesome to wait for the screw to fly off before maintenance.

3: Cleaning of lenses

Clean before work every day, and the equipment must be turned off when cleaning, there are 3 mirrors and 1 mirror on the engraving machine Focusing mirror (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, the No. 3 mirror is located on the top of the fixed part of the laser head, and the focusing mirror is located at the lower part of the laser head. Adjusted lens barrel), the laser is reflected by these mirrors, focused and emitted from the laser head. The lens is easily stained with dust or other contaminants, causing laser wear or damage to the lens. No. 1 and No. 2 lenses do not need to be removed when cleaning. Edge rotary wipe. The No. 3 lens and the focusing lens need to be taken out of the frame, wiped in the same way, and then put back as they are after wiping. Here, Guangzhou laser machine reminds everyone that when wiping the lens, be very careful not to mess or break the lens, otherwise it is not maintenance, but damage to the laser machine.

Four: Inspection of the 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 for the focusing mirror, but the three mirrors are fixed by the mechanical part, and the possibility of offset is high. Although the offset usually does not occur, it is still necessary to remind the user to be sure before each work. Check whether the light path is normal.

Five: Water replacement and water tank cleaning

Clean the water tank and replace it every week Circulating water once, the water 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°C. If it exceeds 35°C, the circulating water needs to be replaced, or ice cubes are added to the water to reduce the water temperature. The user can choose a cooler, or use two water tanks. Cleaning 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 to the water tank, insert the water pipe connecting the water pump into the water inlet, and arrange the joints. Power on the water pump separately and run it for 2-3 minutes (to fill the laser tube with circulating water)

Six: Precautions

The lens should be wiped gently, Do not damage the surface coating; 2. The wiping process should be handled with care to prevent falling; 3. Please keep the concave side down when installing the focusing mirror.
