Laser engraving machine maintenance points:
1.The laser tube installation fulcrum should be reasonable. The fulcrum should be at 1/4 of the total length of the laser tube. Otherwise, the laser tube spot pattern will be deteriorated. Some working spots will become several points for a period of time, causing the laser power to drop to meet the requirements. Constantly change the tube, carefully read the “Notes on the use of laser tubes.”
2.The cooling system should be grounded, often clean the water tank and waterway, the temperature control point of the refrigeration temperature control water tank should be reasonable, otherwise the laser tube is easy to break and the dew condensation power is reduced, the cold head of the tube falls off, the life is greatly shortened, sometimes it can not work, resulting in Constantly changing the tube.
3.Water protection should be checked and cleaned frequently, cooling water can not be washed water protection float switch or water protection float switch is not reset, can not use short-circuit method to solve the urgent need. The cooling water quality should be good. The aluminum oxide of the nozzle is too serious. It should be cleaned regularly for the water in the water pump and the water pipe and the water protection. Otherwise, the laser tube will burst or the cold head will fall off.
4.The suction device should be regularly checked and cleaned, clean the fan duct. Otherwise, a lot of smoke and dust can not be discharged, and the lens and the laser tube are seriously and quickly contaminated, so that the mechanical and electronic components are easily oxidized and the contact is not good.
5.Focusing mirror and mirror inspection, work for a while, the frame will be hot, the surface of the lens will be discolored and rusted; the film cracking is the object to be replaced, especially for many customers using atmospheric pumps and air compressors, so that the focusing lens Water accumulates quickly, so it is necessary to check the cleaning and quality of the optical system of the lens (laser tube exit) on time.
6.The machine working environment can not be too bad, if the ambient temperature is higher than 30 degrees, below 18 degrees, too much dust, serious air pollution, so the machine is seriously damaged, the failure rate is rising; the electrical accessories in the humid environment is easy Something went wrong. Therefore, we especially remind customers to improve the working environment and maintain the machine frequently.
7.The power grid should be matched. The power distribution and contact points of all parts of the whole equipment should be good (fan, water cooler, laser machine, laser power supply, computer should be powered independently).
8.The working current of the laser tube should be reasonable, and it can not be used for 90-100 light intensity for a long time; it is necessary to rationalize the application of laser and save laser energy; the optical path system should be cleaned correctly, otherwise the laser tube will be prematurely aged and cracked, so the laser machine works brightly. Should be adjusted at 50-60% and then adjust the working speed according to the material, this is the best working state of the laser tube.
9.The bottom plate and the processed material should be flat. Otherwise, the focal length will be inconsistent and some places will not be worn. This will increase the light intensity and cause the laser tube to age quickly.
10.Laser power supply cooling should be smooth, otherwise the operating current is increased by 50% or more, the temperature rises very high, so that the laser power failure rate increases.
