Analysis of the failure causes of the uneven marking result of the laser marking machine

Views：1748One of the common problems is that the marking effect of the laser marking machine is not even, which is mainly manifested in the obvious bulge at the bottom when cleaning, and the obvious uneven marking effect at the horizontal and vertical joints when micro carving; In marking, there is a prominent raised vertical line between characters and non-characters. The heavier the marking, the more obvious the phenomenon will be.
The causes for marking uneven effect are as follows:
1. The laser switching power supply is unstable.
2. The production processing speed is too fast to keep up with the response time of the laser tube.
3. The deviation of the light path or the wrong focal length will cause the transmission of light and the uneven bottom.
4. The selection of focusing lenses is unscientific, and short focus lenses should be selected as far as possible to improve the light quality.
The solutions for removing the uneven marking effect are as follows:
1. Replace the laser switch power supply for detection.
2. Reduce the production processing rate.
3. Check the light path to ensure that it is proper.
4. Short focus lenses shall be used, and the focus adjustment shall take into account the deep layer of production and processing
