How to adjust the height of small laser marking machine

The reason why small laser marking machines are more practical in the market is that the equipment can mark each product, highlighting the anti-counterfeiting performance, as well as more important functions, marking depth and clarity. Why are these two important criteria too? Because if the depth of the imprint engraved by the laser marking machine is not enough, it is easy to make the imprint not clear enough, so that counterfeiters are rampant, so these two are also important indicators.

The small laser marking machine sometimes encounters in the process of use, the marking depth is not enough, and the marking height needs to be adjusted How to adjust it? There are mainly the following methods.

1. Direct adjustment method: increase the power of the laser, as we all know, the laser is the core component of the laser marking machine, just like the engine of the car. In order to improve the quality of the laser, the confinement of the laser beam can be increased. This means increasing the laser power. Provide their workload, but doing so increases the cost of the machine. But it is certain that the effect is immediate. Another point is that once the laser is upgraded and his corresponding supporting equipment is upgraded, it will increase the cost of the machine.

2. Replace the field lens of the laser marking machine and replace it with a smaller one. After the replacement, the rays emitted by the laser marking machine will also deepen the depth. The field lens is 110, and now it is replaced with 50, so the depth may be about 2 times before.

3. Adjust the beam of the laser marking machine: Here you need to adjust the laser cavity or replace the light guide material, or upgrade the laser full mirror and output mirror.

For example, semiconductor laser marking machine, adding small holes, increasing the cooling accuracy, adjusting the laser mode light, making the laser large, round and bright. In short, it is to improve the configuration of the laser cavity, which is to understand the structure of the laser marking machine, otherwise the loss will directly affect the device.

4. The marking speed of the laser marking machine is slow, the power is the same, and other parameters are the same, but the marking speed is adjusted. , the depth of the marking process is slightly deepened. That is, when you let it slow down, when you start it, it goes deeper.

5. For marking accessories, replace high-quality lasers with high-quality lasers. The spot is to use a beam expander to process is a good way, eg the degree of laser focus will be strong, the ideal spot will be the result. Machines, such as semiconductor laser marking machines, use imported Q switches, which will be better for depth marking.
