How To Maintain Laser Marking Machine
Jul 16, 2018

Step / Method:

Fan cleaning: The long-term use of the 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 there is insufficient suction of the fan, the power supply is first turned off, the air inlet pipe and the air outlet pipe on the fan are removed, the dust inside is removed, then the fan is inverted, and the fan blades are pulled up until it is clean. Then install the fan.

Fastening of screws and couplings: After the working system is working for a period of time, the screws and couplings at the joints will be loose, which will affect the smoothness of the mechanical movement. Therefore, it is necessary to observe whether the transmission parts are different during the operation of the machine. If the problem is loud or abnormal, the problem should be found to be sturdy and maintained in time. 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.

Cleaning of the lens: (It is recommended to clean before work every day, the equipment must be turned off) There are 3 mirrors and 1 focusing mirror on the engraving machine (the No. 1 mirror is located at the exit of the laser tube, which is the upper left corner of the machine, 2 The mirror is located at the left end of the beam, the mirror No. 3 is located at the top of the fixed portion of the laser head, and the focusing lens is located in the adjustable barrel of the lower part of the laser head. The laser is reflected by these lenses and 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. Rotary wipe. The No. 3 lens and the focusing lens need to be taken out from the frame, and wiped in the same way. After the wiping is completed, the original lens can be loaded back.

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. In the optical path, there is no offset problem in the focusing mirror, but the three mirrors are fixed by the mechanical part, offset It is more likely, although there is usually no offset, but it is recommended that users check whether the light path is normal before each work.

Water replacement and water tank cleaning: Clean the water tank once a week and replace the circulating water once. 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. (It is recommended that the user choose a cooling machine or use two water tanks). 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, 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 (fill the laser tube with circulating water)
