If the marking depth cannot reach the ideal depth, how to solve this problem: First, adjust the laser power and increase the power. If the problem is not resolved, continue to the next step. 2. Focus adjustment. Adjust to a reasonable position. The height of the product is different, and both plane and non-plane focus need to be readjusted. Third, the marking speed is too fast, so slow down. There may be other reasons why the adjustment parameters cannot meet the requirements. We should analyze this problem from other aspects. 1. If the lens is used for a long time, there may be dust on the surface. Please note. 2. The power supply has been used for too long, is it still in a stable state? 3. Whether the beam expansion position and direction are accurate. Fourth, whether the optical path adjustment is accurate, and the optical path will also affect the marking depth of the marking machine. 5. If the laser has been used for too long and the beam becomes weak, the laser needs to be replaced or continuously checked. If the marked graphics do not meet the standard or are very different, it is generally a problem with the galvanometer. For example, a standard square is printed as a trapezoid or deformed when marked. This method may be a galvanometer problem. If changing the galvanometer cannot meet the requirements, it may be related to the uneven surface of the marked object. It is best to use visual positioning if necessary. This solution corrects the galvanometer signal. If the hardware fix still doesn't solve the problem, then choose the software fix. The line printed by the laser marking machine is a dotted line. How to solve this problem: 1. Poor signal connection leads to unstable transmission. Second, there may be a problem with the signal connection cable. Third, whether the card insertion position is accurate may also cause problems. Fourth, the signal may be interfered. Keep sources of interference away from the marking machine. 5. Interference marks caused by unstable power output.
