Practical knowledge of laser engraving machine:

  Installation: laser engraving machine laser tube installation pivot point to be reasonable, the pivot point in the laser tube 1/4, otherwise the laser tube spot pattern deterioration, some work for a period of time spot into several points, resulting in a decline in laser power can not meet the requirements; cooling system to ground, often clean the water tank and waterway, refrigeration temperature control tank control point to be reasonable, otherwise the laser tube breakage and condensation power decline, the tube of the cold water head off The life span of the laser tube is greatly shortened, and sometimes can not work.

 Cleaning: water protection inspection and cleaning, cooling water often can not flush open water protection float shape or water protection float switch does not reset, cooling water quality should be good, water nozzle aluminum oxide is too serious, use a period of time to regularly clean the pump and water pipe, water protection in the dust and dirt, or cause the laser tube burst or cold water head off; suction device inspection and cleaning, the fan duct clean, or smoke dust can not be discharged, will seriously The lens and laser tube contamination, so that the mechanical and electronic components are easy to oxidation of thousands of poor contact; optical system to clean the correct, or premature aging and rupture of the laser tube; clean the moving parts of the machine, so that the machine can always be in excellent working condition.

  Laser tube: laser tube is a glass product, fragile, installation and use, avoid local stress; laser tube in the work process, can not have scale in the cooling water tube open into, so as not to cause cooling water blockage, poor heat dissipation, if the emergence of scale is found, available 20% dilute hydrochloric acid cleaning cooling tube, remove the scale before use; laser tube of the two support points to be in the laser tube two end points 1/4 of the total length or in the logo point, to ensure that the cooling water flow in 2L ~ 4L / min, otherwise it will cause jumping mode, resulting in a decline in laser power; customers are recommended to use special cooling equipment for laser equipment, which can extend the service life of the laser tube.

  Check: laser engraving machine focusing mirror and reflector inspection, work for a while the mirror frame will heat up, the lens surface discoloration rust; decoupling cracking are among the objects to be replaced, especially many customers with large air pumps and air compressors, so that the focusing lens on the water soon accumulate; power grid power root match, the whole equipment of the various parts of the power distribution and contact points to be good; honeycomb base plate to be flat, or cause inconsistent focal length some places Cut not through, so as to increase the light intensity, will also cause the laser tube aging.

  Environment: the machine working environment is too harsh, the indoor temperature is higher than 40 ℃, below 0 ℃ under the dust is too much, air pollution is serious, so that the machine is seriously damaged, the failure is rising, the humid environment of the electrical accessories are easy to go wrong. Working in an environment where the temperature does not exceed 30 ℃, please first connect the cooling water, using the principle of low into high, adjust the position of the outlet pipe to ensure that the cooling water is full of laser tube, the tube can not contain air bubbles, and then turn on the power.

  Intensity: laser tube working current to be reasonable, can not be in the long-term 900 ~ 100 light intensity work. Laser power supply heat dissipation to be smooth, otherwise the working current to adjust more than 50% of the temperature rise very high, so that the laser power failure rate increases.

  Machine installation and disassembly: laser engraving machine in the installation or disassembly, the first thing to do is to observe that the machine of the transmission part and the law of its movement of each part of the structure, the movement of the place to pay attention to its concentricity, verticality, parallelism, straightness, is to listen to the machine after the installation and disassembly for safety reasons, the first test machine with hand support, nothing abnormal and then pass the machine, listen carefully to each sound issued by the machine, the whole machine Achieve low noise, no noise, the opposite is not normal, must be re-installed debugging.

  Motion system: after the replacement of the guide rail to pay attention to its parallelism, hand push glide, to be flexible and free in the movement of the guide rail a little to ensure that it can be uniform linear motion, the slider in the disassembly to understand its structure, it is a combination of many fractional steel ball, improper installation methods, will lead to fall off; regular cleaning, replace the grease on the screw, and then use anti-rust oil, cleaning the screw, cleaning before the screw The optical shaft and pulley underneath are separated by cloth so that the dirt falling down during cleaning will not damage the optical shaft and metal pulley. Clean the connecting parts and the screws that can be touched, and coat their surfaces with machine oil so that they will not be affected by rusting and disassembly.
