The thickness of the protective layer is only 0.4 mm, can the original screen surface completely covered to protect against external damage, scratches, adds shock absorption, five times higher than standard PET film. It does not affect the video effect screen. In this case on the basis of the power laser marking machine, launched a glass oxygen Mask, based on the protection of mobile phone screen to prevent the phone blue radiation on the human body injury, prevention of myopia, man-machine dual protection. Marking appear wavy line, marking the first machine with a slight cry, galvanometer drive plate heat slightly (interference occurs) Check the grounding cable is properly connected (best grounding method is: X galvanometer signal ground, Y galvanometer signal, the shield wire, 220V power earth, and marking the cabinet to be communicated), after interference if the ground is still connected, first check whether the normal marking Kaka (check method is confirmed with a well-played put on standard cards, marking see whether there is still interference), if there is still interference mobile phone accessories laser marking machine, then further examination galvanometer motor cable is intact, and the other cable is wound, if everything is normal, first with a confirmation intact galvanometer driver board replaced, if not interference, you can conclude that there is a problem galvo driver board; if interference data wire laser marking machine, the galvanometer motor problems. (Of course the company out laser maintenance personnel, make sure that good, if the customer is three years ago galvanometer laser marking machine products, the ability to resist interference products will almost certainly, galvo marking head periphery if there is a mobile phone signal, RF signal exposed motors, electrical, magnetic, or is Q-switch may affect new galvanometer can have this happen) data wire laser marking machine, laser marking machine Luohu, fiber laser marking machine by Dongguan Guan Jun Laser Equipment Co.
