What is the root cause of common failures that cause uneven marking of laser marking machines? The use of laser marking machines is very common, especially in the field of craft products, which is favored by customers. Many customers rely on the laser CNC engraving machine to make the first pot of gold for laser cleaning machine manufacturers and get rich.
But equipment is also like a human being. With the increase in use time and the damage of parts, various problems will occur in the equipment. The same is true of the laser CNC engraving machine, which is likely to cause unfair cleaning of the bottom.
So, what is actually going on to cause the CNC engraving machine to have a common fault phenomenon of uneven bottom cleaning? How can I solve it myself? I have sorted out the following materials today for your reference.
It is one of the common problems that the marking effect of laser marking machine is not leveled. It is mainly manifested as a significant bulge phenomenon at the bottom during cleaning, and the phenomenon of negative engraving is that there is a significant marking effect at the junction of the horizontal and vertical. , there is a prominent vertical line between the characters with and without characters, the heavier the marking, the more obvious the phenomenon.
The reasons for the uneven marking effect are as follows:
1. The light output of the laser switching power supply is unstable.
2. The production and processing rate is too fast, and the response time of the laser tube cannot keep up.
3. The optical path is deviated or the focal length is wrong, resulting in transmitted light and uneven bottom end.
4. The selection of focusing lenses is unscientific. Short focal length spectacle lenses should be selected as much as possible to improve the light quality.
The marking effect is not leveled and the solution is as follows:
1. Remove and replace the laser switching power supply detection.
2. Reduce the production and processing rate.
3. Check the optical path to ensure that the optical path is appropriate.
