[Summary Description] Installation: The laser tube installation fulcrum of the laser engraving machine should be reasonable, with the fulcrum at 1/4 of the laser tube. Otherwise, it will cause the laser tube spot mode to deteriorate, and some work for a period of time will cause the spot to become several points, resulting in a decrease in laser power that cannot meet the requirements; The cooling system should be grounded, and the water tank and waterways should be cleaned frequently. The control points of the cooling and temperature controlled water tank should be reasonable, otherwise it may cause damage to the laser tube, decrease in condensation power, detachment of the cold water head of the tube, greatly shorten its lifespan, and sometimes fail to work.

Practical knowledge of laser engraving machines:

Installation: The laser tube installation fulcrum of the laser engraving machine should be reasonable, with the fulcrum at 1/4 of the laser tube, otherwise the laser tube spot mode will deteriorate, and some work for a period of time will cause the spot to become several points, resulting in a decrease in laser power that cannot meet the requirements; The cooling system should be grounded, and the water tank and waterways should be cleaned frequently. The control points of the cooling and temperature controlled water tank should be reasonable, otherwise it may cause damage to the laser tube, decrease in condensation power, detachment of the cold water head of the tube, greatly shorten its lifespan, and sometimes fail to work.

Cleaning: Water protection inspection and cleaning. Cooling water often cannot flush. The shape of the water protection float or the water protection float switch does not reset. The cooling water quality is good, and the aluminum oxide in the water nozzle is too severe. After using it for a period of time, it is necessary to regularly clean the water pump, water pipe, and dust in the water protection, otherwise it may cause the laser tube to burst or the cold water head to fall off; Check and clean the suction device, and clean the fan air duct. Otherwise, smoke and dust cannot be discharged, which will seriously pollute the lens and laser tube, making various mechanical and electronic components prone to oxidation and poor contact; The optical system should be cleaned correctly, otherwise it may cause premature aging and rupture of the laser tube; Clean the moving parts of the machine to ensure that it remains in excellent working condition.

Laser tube: The laser tube is made of glass and is fragile. When installing and using it, avoid local stress; During the working process of the laser tube, there should be no scale inside the cooling water pipe to prevent blockage of the cooling water and poor heat dissipation effect. If scale is found, the cooling pipe can be cleaned with 20% dilute hydrochloric acid, and the scale can be removed before use; The two supporting points of the laser tube should be 1/4 of the total length at both ends of the laser tube or at the marked points, ensuring that the cooling water flow rate is between 2L and 4L/minute, otherwise it will cause mode hopping and lead to a decrease in laser power; Suggest customers to choose specialized cooling equipment for laser equipment, which can maximize the service life of laser tubes.

Inspection: Laser engraving machine focusing mirror and reflector inspection. After working for a while, the mirror frame will heat up, and the surface of the lens will change color and rust; Film detachment and cracking are all objects that need to be replaced, especially for many customers who use large air pumps and compressors, which quickly accumulates water on the focusing lens; The power root of the power grid should be matched, and the power distribution and contact points of each part of the entire equipment should be good; The honeycomb base plate should be flat, otherwise it may cause inconsistent focal length and some areas cannot be cut through. This will increase the light intensity and also cause the laser tube to age.

Environment: The working environment of the machine is too harsh. When the indoor temperature is above 40 ℃ and below 0 ℃, there is too much dust and air pollution. This causes serious damage to the machine, and faults continue to rise. In humid environments, various electrical accessories are prone to problems. When working in an environment with a temperature not exceeding 30 ℃, please first connect the cooling water and use the principle of low inlet and high outlet. Adjust the position of the outlet pipe to ensure that the cooling water is filled with the laser tube and there are no bubbles inside the tube. Then turn on the power.

Intensity: The working current of the laser tube should be reasonable and cannot be operated at a light intensity of 900~100 for a long time. The heat dissipation of the laser power supply should be smooth, otherwise the working current should be adjusted by more than 50%, and the temperature rise will be very high, which will increase the failure rate of the laser power supply.

Machine assembly and disassembly: When installing or disassembling a laser engraving machine, the first thing to do is to observe the transmission parts of the machine and their movement patterns. The structure of each component should pay attention to its concentricity, verticality, parallelism, and straightness when moving. After installing and disassembling the machine, for safety reasons, first use your hands to test the machine. If there are no abnormalities, turn on the machine and carefully listen to each sound emitted by the machine, The entire machine has achieved low noise and no noise, otherwise it is abnormal and needs to be reinstalled and debugged.

Motion system: After replacing the guide rail, attention should be paid to its parallelism. When manually pushing and sliding, it should be flexible and free. The movement of the guide rail should ensure that it can move uniformly in a straight line. When disassembling the slider, it is necessary to first understand its structure. It is composed of many decimal point steel balls, and improper installation methods can lead to detachment; Regularly clean and replace the grease on the screw rod, and then use rust proof oil to clean the screw rod. Before cleaning, separate the optical shaft and pulley below the screw rod with a cloth to prevent dirt falling during cleaning from damaging the optical shaft and metal pulley. Clean the connecting components and accessible screws, apply oil to their surfaces to prevent rust from affecting disassembly.
