The solution to the shallow marking depth of High power 10 Watt 355 laser

In the process of using the UV laser marking machine, we will encounter some small problems, which cause the UV laser marking machine to not work normally and stably. At this time, we must use professional knowledge to find out the problem and analyze the problem, and then solve it. question. Today, let's take a look at the solution to the shallow depth of UV laser marking machine.

The general cause of the shallow marking depth of the UV laser marking machine is that there is no specific solution caused by improper operation. Start from the following aspects.

1. Confirm whether the speed of the UV laser marking machine is too fast. If the marking speed of the UV laser marking machine is too fast, it will cause the beam to end before the marking effect is achieved. Cause the text or pattern depth is not enough and unclear.

2. Confirm whether the lens of the UV laser marking machine is clean. If the lens is too dirty, the emitted laser beam cannot be expanded and focused, which will affect the marking effect and the position will change slightly. Fine-tune each lens of the resonator to make The spot is optimized. If the lens is too dirty, you can use a cotton swab dipped in alcohol for scrubbing. This cleaning method is effective and will not damage the parts of the laser engraving laser machine.

3. Check whether the laser of the UV laser marking machine deviates from the center point after entering the galvanometer. The deviation of the optical path from the center causes the beam to not be concentrated in the corresponding marking area, so the marking pattern and text will become very shallow. At this time, you can use the frequency multiplier to adjust the optical path to restore the normal state.

4. Determine whether it is a problem with the krypton lamp. If the current of the UV laser marking machine is adjusted to 25A, the marking depth of the laser is not strong enough, then it means that the problem is with the krypton lamp, and the krypton lamp needs to be replaced.

5. Check whether the output current of the acousto-optical power supply is low or the position of the acousto-optical crystal is shifted, increase the current of the acousto-optical power supply or correct the position of the acousto-optical crystal, if the power supply current is too small, the beam is too small or the marking frequency appears abnormal, thus affecting the marking effect. Generally, the larger the current of the laser engraving machine, the higher the marking intensity will be.

By checking the above points and buying a few books, the problem of shallow marking depth of the UV laser marking machine can be solved. It is worth emphasizing that when we use the UV laser marking machine, we must operate correctly according to the operating specifications, and pay attention to the usual The working state of the laser marking machine can ensure that there is no failure problem.
