Correct maintenance and maintenance method of a laser die cutting machine


Correct maintenance and maintenance method of a laser die cutting machine



Many customers do not know how to maintain and maintain the laser die cutting machine when they use the laser die cutting machine, which leads to the accelerated aging of the machine. Now, Test Laser Xiaosheng will popularize some maintenance and maintenance methods for the laser die cutting machine:


1. Tank water and tank cleaning

Suggestion: Clean the water tank and replace the circulating water once a week

Note: The laser tube must be filled with circulating water before the machine works.

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 (it is recommended that the user 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 alone and run it for 2-3 minutes (to fill the laser tube with circulating water).

2. Laser exhaust fan cleaning

The long-term use of the fan will cause a lot of solid dust and debris to accumulate in the fan, which will make the fan generate a lot of noise, and is not conducive to exhaust and deodorization. When the suction power of the fan is insufficient and the smoke exhaust is not smooth, first turn off the power supply, remove the air inlet duct and the air outlet duct on the fan, remove the dust and sundries inside, then turn the fan upside down, and pull out the fan blades inside, Clean with a rag, then install the fan.


3. Cleaning of the lens

(It is recommended to clean before work every day, and the equipment must be turned off)

There are 3 mirrors and 1 focusing mirror on the laser die cutter (gantry type structure) (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 3 The No. 1 reflector is located on the top of the fixed part of the laser head, and the focusing mirror is located in the adjustable lens barrel at the lower part of the laser head). The laser is reflected and focused by these mirrors 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 from the frame, wiped in the same way, and then put back as they are after wiping. (The structure of the cross slide does not consider so many reflections, it has only one mirror)


Notes: 1. The lens should be wiped gently to avoid damaging 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 lens.


4. Cleaning of guide rails

As one of the core components of the equipment, the guide rail and the linear axis play a guiding and supporting role. In order to ensure the high machining accuracy of the machine, its guide rails and straight lines are required to have high 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 workpiece, and these smoke and dust will be deposited on the surface of the guide rail and linear axis for a long time, which has a great impact on the processing accuracy of the equipment, and will Corrosion spots are formed on the surface of the linear shaft of the guide rail, which shortens the service life of the equipment. In order to make the machine work normally and stably and ensure the processing quality of the product, it is necessary to do a good job in the daily maintenance of the guide rail and linear axis.

Note: Please prepare dry cotton cloth and lubricating oil for cleaning the guide rail;

5. Fastening of screws and couplings

After the motion system works for a period of time, the screws and couplings at the motion joints will be loose, which will affect the stability of the mechanical movement. Therefore, during the operation of the machine, it is necessary to observe whether there is abnormal noise or abnormal phenomenon in the transmission parts, and find problems in time. Sturdy and maintained. At the same time, the machine should tighten the screws one by one with a tool over a period of time. The first firming should be about a month after the device is used.


6. Inspection of the optical path

The optical path system of the laser knife die 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 relatively high. Although the deviation usually does not occur, it is recommended that the user must check whether the optical path of the laser die cutting machine is normal before each work.

Do the above 6 points well, the life of the machine will be at least 5-10 years longer.
