           Inspection: laser engraving machine focusing mirror and reflector inspection, the frame will heat up after working for a while, the surface of the lens will become discolored and rusty; peeling and film cracking are all objects to be replaced, especially many customers use atmospheric pumps and air compressors. In this way, water will quickly accumulate on the focusing lens; the power roots of the power grid match, and the power distribution and contact points of each part of the entire device should be good; the honeycomb bottom plate should be flat, otherwise the focal length will be inconsistent, and some places will not be worn, so it is necessary to put Increased light intensity will also cause the laser tube to age.         Environment: The working environment of the machine is too bad. The indoor temperature is higher than 40°C and lower than 0°C. There is too much dust and serious air pollution. In this way, the machine is seriously damaged and the faults continue to rise. It is easy for the

          The daily maintenance and maintenance of the laser cutting machine is very important, because the price of the laser cutting machine is not low, ranging from hundreds of thousands to millions, so as long as possible to extend the life of the laser cutting machine to better save production Cost, to win greater benefits. Which specific aspects should be maintained from the following aspects:         1.Replacement of circulating water and cleaning of water tank. Before the machine works, make sure that the laser tube is filled with circulating water. The water quality and temperature of the circulating water directly affect the service life of the laser tube. Therefore, it is necessary to regularly replace the circulating water and clean the water tank. This is best done once a week.　        2. the fan is clean. Long-term use of the fan in the machine will cause a lot of solid dust to accumulate in the fan, which will cause a lot of noise in the fan, and it is not conducive

1. The fulcrum of laser tube installation should be reasonable, the fulcrum should be at 1/4 of the total length of the laser tube, otherwise the laser beam spot mode will be deteriorated, and the spot will become a few points during some working periods, so that the laser power cannot be reduced. As a result of continuous tube changes, read “Precautions for the use of laser tubes”.2. The cooling system should be grounded, and the water tank and water circuit should be cleaned frequently. The temperature control point of the cooling temperature control water tank should be reasonable, otherwise it will cause the laser tube to be easily damaged and the dew condensation power will drop, the cold head of the tube will fall off, the life will be greatly shortened, and sometimes it will not work. Causes constant tube changes. 3. The water protection should be checked and cleaned frequently. The cooling water can often not be flushed with the water protection float switch or the water protection float switch is not reset, and the short circuit method

1. Whether the focal length is adjusted properly. 2. Whether there is too much paper soaked in water on the engraved material, or whether there is too much water on the paper. 3. Whether the laser tube is aging. 4. Whether the optical path is correct. (Recorrect) 5. The lens is dirty and the dust is too thick. 6. Broken lens. 7. The laser tube head is contaminated. 

1. The laser head does not emit light 1. Press the test button on the operation panel to check the status of the ammeter: (super high-speed machine, low-speed machine has an ammeter, other models are not equipped, you can install it yourself) ①No current: Check whether the laser power supply is connected, whether the high-voltage line is loose or falling off, and whether the signal line is loose and disconnected; ②Electrical current: check whether the lens is broken or the optical path is seriously shifted; ③ There is a problem with the laser tube or laser power supply; ④ Is there any problem with the main board or wiring board; 2. Check whether the water circulation system is normal: ①No water: check whether the pump is damaged or not powered; ②Water: Check whether the water inlet and outlet are reversed or the water pipe is broken; ③ Whether the water protection is damaged and whether the water protection line is broken; 3.It can be fired, self-checked, and the transmitted data does not emit light (check whether the computer settings are

        The first method: Since the light spot is the smallest at the focal point of the laser cutting machine, press the “Spot” key to determine the focal length according to the size of the light spot. That is, when the light spot is the smallest, it can be regarded as the optimal height of the laser head when cutting the object. Put an object under the laser head and adjust the height of the laser head. When the laser head is at a different height, press the “Spot” button to observe the size of the light spot. You can adjust the position of the laser head to find out The area of ​​the laser head with a small light spot, and then finely adjust the height of the laser head in this area. When the light spot is the smallest, it can be regarded as the position of the laser head we want to adjust.         The second method: Since the light intensity is the strongest at the laser focal length of the

        The laser engraving machine is a processing device that uses laser as an energy source. The stability of the laser also directly affects the ability to process. Whether the device can be used depends entirely on whether the laser tube can output normal intensity. laser. There are many reasons for the weakening of the laser, some are caused by external factors, and some are caused by the laser tube itself. This requires us to determine the cause more quickly and accurately, and to solve it as soon as possible to resume production. . Laser please pay attention:         Whether the cooling water quality or water temperature is normal: replace the clean cooling water and let it reach normal temperature. Whether the reflective lens is contaminated or damaged: clean or replace the reflective lens.         Whether the laser power supply is damaged: replace the laser power supply.         Whether the focal length of the focus changes: adjust the focal length again.         Whether the laser

         Laser chiller is a kind of water cooling equipment, which is mainly used for cooling by circulating cooling water tank. It has the functions of constant temperature, constant pressure and constant flow. It is also called on the market: laser chilled water tank, chiller, constant temperature cooler, water cooling machine……         As the name implies, it cools the pure water in the water tank by the compressor’s cooling capacity, and then brings the cooling water into the cavity of the laser machine to cool the heat generating module of the laser machine, the laser cavity and the Q head, especially when the Q head is working. The temperature is very high, if there is no water or no chiller, it may work for 3 seconds and the Q head will burn out. The laser chiller is also equipped with a water filter, which can filter impurities in the circulating water, prevent the pipeline from being clogged, and make the laser equipment safer. The laser machine uses a Hitachi imported compressor, which has a

          Although the protective lens of the laser cutting machine is a wearing part, in order to improve its utilization rate and reduce production costs, the protective lens can be cleaned regularly to achieve the purpose of reuse. The following are the three cleaning steps summarized by the high-energy laser:         1. The protective lens material is ZnSe (zincized arsenic), which is relatively brittle and afraid of falling; be careful when disassembling: do not use too much force and do not collide with hard objects. There is an antireflection coating on the surface, which is afraid of pollution, moisture, oiliness, and scratching; therefore, it is required to provide dry and degreased air in the work. Never handle the laser cutting machine directly to protect the lens of the lens because of skin oil Will cause permanent damage to the lens surface. On the contrary, you can wear gloves and its special set for operation. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used
