Light marking common problems and solutions Fault 1: laser intensity decreased, marking marking machine is not clear enough workaround: ① whether the laser resonator changes; tuning resonator lenses. The best spot of the output; ② acousto-optic crystal sound and light power output offset or low energy; adjust sound and light crystal position or increase the sound and light power supply current; ③ enter galvanometer laser off center: adjust the laser; ④ If the current transfer 20A to remain sensitive about strong enough: krypton lamp aging, replacement lamps. Fault 2: krypton lamp can not be triggered (see NTP power usage manual) Marking Solution: ① Check all power cable; ② high pressure krypton lamp aging, replacement krypton lamp. Operation Laser Marking Machine Note ① Do not water or normal water cycle starts when the laser power and Q-power; ② Q power load is not allowed to work (ie, Q-power output vacant); ③ abnormal phenomenon, first turn off galvanometer switch and key switch, re-examination; ④ not allowed to start before the krypton lamp lit other components to prevent damage to the components of the high-pressure fleeing; ⑤ note that laser power output (anode) vacant, to prevent ignition and other electrical appliances, breakdown; ⑥ keep a clean recycled water. Periodically clean the tank and replaced with deionized water or clean water. Marking machine krypton lamp and replace the use of closed water-cooled machines, laser power. Open the upper three cavity cover, remove to replace the lamp or crystal, the replacement into, and put on the chamber cover. Open water-cooled machine, laser power Dongguan Hengli laser marking machine maintenance, the laser power supply current is set (15 ~ 20) A so. Place a small wood or black paper between the diaphragm and the first beam expander, you should see the spot formed by laser ablation. If not, minor adjustments to the former three knobs diaphragm frame, until the spot appears. After three knobs laser commissioning out before adjustment should be repeated so that the diaphragm frame strongest spot, such as a laser is too strong, high brightness can not be observed, can reduce the supply current. Turn off the laser power. Shenzhen Wang Tak professional fiber laser marking machine maintenance, semiconductor marking machine maintenance, end-pumped marking machine maintenance end-pumped laser marking machine principle end-pumped laser marking machine using the most advanced laser technology, direct The wavelength of the laser crystal is from the end face of the optical pumped 0.808μm. Output generated by the laser optics. Making the photoelectric conversion efficiency of laser greatly improve Dongguan bridge laser marking machine maintenance, can reach more than 45%, while the pump source mate reduce power consumption. End-pumped better than the side of the pump beam quality and high peak power. Advantages and scope of application: 1, the output of the laser spot is smaller, marking lines smaller. 2, good beam quality, high stability of the output laser Dongguan Shek Pai laser marking machine maintenance, marking effect easier to debug. 3, the laser frequency is high, marking faster. 4 laser marking machine maintenance, stable performance, small size and low power consumption. 5, especially for translucent keys laser engraving products.
