1. Using off-focus marking, the focusing lens has a corresponding focal depth range, and using the off-focus method will easily lead to a large-scale marking pattern, the edge is at the focal depth critical point or beyond the focal depth range. It is easy to cause unevenness of the effect.
2. It may also be that the deflection lens of the vibrating mirror is damaged. When the laser beam passes through the damaged area of the lens, it cannot be reflected well. Therefore, the laser energy of the laser passing through the damaged area of the lens is different, and the laser energy acting on the material is also different, so that the marking effect is uneven.
3. If the laser vibrating lens is not parallel to the processing table, it will also cause uneven effect. Because of the imbalance, the energy density is different.
4. Part of the output spot is blocked, that is to say, the laser beam is missing and incomplete after passing through the vibrating mirror, etc.
The laser output head, fixed equipment and vibrating mirror are not properly adjusted, which will cause part of the laser spot to be blocked.
5. Thermal lens phenomenon. When the laser is refracted and reflected, it will cause the lens to heat up and produce slight deformation. This deformation will increase the focus of the laser, and the shortening of the focal length will also cause uneven marking.
6. If there is no problem with the inspection machine, the thickness of the material will be uneven. Usually the material is more sensitive to the laser reaction, and the laser energy reaches the material destruction threshold is certain. The coating thickness of the material is different and the effect is not uniform.
