Laser engraving machine classification
Laser laser engraving machine in accordance with the different lasers can be divided into: CO2 laser engraving machine, semiconductor laser engraving machine, YAG laser engraving machine, fiber laser engraving machine. In accordance with the laser visibility is divided into: ultraviolet laser laser engraving machine (invisible), green laser laser engraving machine (invisible laser), infrared laser engraving machine (visible laser), in accordance with the classification of laser wavelength Laser laser engraving machine in accordance with the laser wavelength can be divided into; 532nm laser laser engraving machine, 808nm laser laser engraving machine, 1064nm laser engraving machine, 10.64um laser laser engraving machine, 266nm laser engraving machine, 10.64um laser engraving machine, laser engraving machine, 10.64um laser engraving machine, laser engraving machine, 10.64um laser engraving machine, laser engraving machine, laser engraving machine, laser engraving machine, laser engraving machine. Laser engraving machine. On the current domestic market in terms of semiconductor laser engraving machine market share is the most. e net laser The production of semiconductor DP laser engraving machine small size, maintenance-free, easy to use, widely used and so on.
Laser laser engraving machine use process Check the water circuit, the circuit is correct before starting. Power on the order of: ① Turn on the incoming power, open the key switch. At this time the machine ventilation and refrigeration system is energized, the ammeter shows the value of 7A or so; ② wait 5 to 10 seconds, press the trigger button on the external control panel, the ammeter shows the value of zero, 3 to 5 seconds after the krypton lamp ignited, the ammeter shows the value of 7A. (Refer to the laser power supply operating instructions); ③ turn on the vibrating mirror power supply; ④ turn on the computer, call out the required marking file; ⑤ adjust the laser power supply to the working current (10 to 18A). ⑤ adjust the laser power supply to the working current (10 ~ 18A), you can start marking; marking is complete, according to the above order in reverse to turn off the components of the power supply: ① laser power supply working current to the minimum (7A or so); ② turn off the computer; ③ turn off the vibration mirror power supply; ④ press the stop button; ⑤ turn off the key switch; ⑥ disconnect the incoming power supply.
Laser laser engraving machine common problems and their solutions
Fault 1: laser intensity drops, marking is not clear enough marking machine solutions: ① laser resonance cavity whether the change; fine-tune the resonance cavity lens. Make the best output spot; ② acousto-optic crystal offset or acousto-optic power source output energy is low; adjust the acousto-optic crystal position or increase the acousto-optic power source operating current; ③ into the vibration mirror laser off-center: adjusting the laser; ④ if the current is adjusted to 20A or so is still not enough to feel the light intensity: krypton lamp aging, replace the new lamp. Marking machine fault 2: krypton lamp can not be triggered (refer to the NTP power supply manual) marking machine solution: ① check all the power supply connection line; ② high pressure krypton lamp aging, replace the krypton lamp. Operating laser laser engraving machine precautions ① prohibited without water or water circulation is not normal to start the laser power supply and Q power supply; ② do not allow the Q power supply no-load work (i.e., Q power supply output suspended); ③ anomalies, first turn off the vibration mirror switch and the key switch, and then check again; ④ not allowed to start the krypton lamp ignition of the other components, in order to prevent high-voltage into the damage to the components; ⑤ attention to the output of laser power supply (anode) suspended, in order to prevent and other krypton lamps ⑤ Pay attention to the laser power supply output (anode) hanging empty, in order to prevent and other electrical appliances fire, breakdown; ⑥ Keep the internal circulating water clean. Regularly clean the water tank and change clean deionized water or pure water. Marking machine krypton lamp use and replacement Close the water cooler, laser power. Open the upper three chamber cover, take out the lamp or crystal to be replaced, replace it and put it in, install the chamber cover. Turn on the water cooler, laser power supply, adjust the laser power supply current to (15~20) A or so. Place 1 small piece of wood or black paper between the front diaphragm and beam expander mirror, and you should see the light spot formed by laser ablation. If not, slightly adjust the three knobs of the front diaphragm holder until the light spot appears. After the laser is debugged out, the three knobs of the front diaphragm holder should be adjusted repeatedly to make the light spot the strongest, such as when the laser is too strong and too bright to observe, the power supply current can be reduced. Turn off the laser power. Special Note: Time to replace the krypton lamp. Krypton lamp in the laser factory instructions krypton lamp life of 300 hours, but due to the different conditions of use of the user, the above time can not be used as the only basis for the replacement of krypton lamp. With the increase in the use of time, the krypton lamp luminous efficiency decreases, the laser output is also weakened, many users in order to obtain sufficient laser output, increase the current of the laser power supply, so that the krypton lamp luminous enhancement, which makes the krypton lamp to accelerate the aging of the formation of a vicious circle, which sometimes leads to blowing up the lamp phenomenon. In order to prevent this phenomenon, we recommend that users decide whether to replace the krypton lamp according to the following method. When replacing a new krypton lamp, record the normal marking laser power supply ammeter value, as the standard current value. When the krypton lamp gradually aging, increase the laser power supply current output, but the ammeter value should not exceed 1.25 times the standard current value. For example: the new krypton lamp marking current value of 20A, after a period of time, if the current value is increased to 25A after the normal marking is still not possible, the krypton lamp should be replaced.
