Cause analysis of uneven effect of laser marking machine

Cause laser marking machine marking effect uneven common root cause of failure? The use of laser marking machine is very common, especially in the field of technological products by customers, many customers rely on laser CNC engraving machine to earn the first barrel of gold laser cleaning machine manufacturers, started to become rich.
But equipment is also like people, with the improvement of use time, parts damage, equipment will occur a variety of problems. Laser CNC engraving machine is the same, it is likely to clean the bottom of the unfair phenomenon.

So, what is the actual cause of CNC engraving machine at the bottom of the cleaning uneven common fault phenomenon? How do you deal with it? Today I comb the following materials for your reference.
Laser marking machine marking effect is one of the common problems, the main performance is the bottom of the cleaning has a significant bulge phenomenon, Yin carving phenomenon for the horizontal and vertical intersection has a significant marking effect is not leveling; Yang carving, there is a significant raised vertical line between the word and no word, the heavier the marking, the more significant the phenomenon.

The reasons for the uneven marking effect are as follows:
1. the laser switching power supply light is unstable.

2. the production and processing rate is too fast, the response time of the laser tube can not keep up.

3. light path deviation or focal length is wrong, resulting in transmitted light, resulting in uneven bottom.

4. focusing lens selection is not scientific, should be selected as far as possible short focal length lenses, improve the quality of light.

The solution to remove the uneven marking effect is shown as follows:

1. Replace the laser switching power supply for detection.

2. reduce the production and processing speed.

3. Check the optical path to ensure that the optical path is appropriate.

4. the use of short focal length lenses, focal length adjustment should take into account the production of the deep processing.
