Reasons and solutions for uneven effect of UV laser marking machine

The application of laser marking machine is very wide, especially in the craft and gift industry, which is favored by customers. Many customers have made their first pot of gold by relying on laser engraving machine and made a fortune.

But machines are like people. With the increase of use time and the wear and tear of parts, the machine will have various problems. The same is true for laser engravers, which may exhibit unequal sweeps at the bottom.

So, what is the specific reason for the uneven bottom of the engraving machine? How can I solve it myself? I have compiled the following information for your reference today.

The uneven marking effect of the laser marking machine is one of the common faults, which is manifested as obvious protrusions at the bottom when cleaning, and obvious horizontal and vertical intersections when engraving The marking effect is not smooth; in the case of positive carving, there are obvious raised horizontal lines between the characters with and without characters, and the deeper the marking, the more obvious the phenomenon.

The reasons for the uneven marking effect are as follows:

1. The laser power supply is unstable.

2. The processing speed is too fast, and the response speed of the laser tube cannot keep up.

3. The optical path is deviated or the focal length is wrong, resulting in scattered beams and uneven bottom.

4. The selection of focusing lens is unreasonable, and the lens with short focal length should be selected as far as possible to improve the beam quality.

The solution to the uneven marking effect is as follows:

1. Replace the laser power supply for testing.

2. Reduce the processing speed.

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

4. Use short focal length lenses, and the focal length adjustment should consider the depth to be processed.
