How to adjust the parameters of UV laser marking machine?

With its fine marking and good material adaptability, UV laser marking machine is currently the most widely used type of laser marking machine. UV laser marking machine is suitable for high-end markets of ultra-fine processing, cosmetics, Medicines, polymer material packaging bottles, flexible PCB boards, silicon wafer micro-holes, glassware, plastic buttons, gifts, communication equipment, etc.

For beginners, the operation of UV laser marking machine may be unfamiliar, such as the adjustment of some parameters, I don't know how to start, today Xiaobian will share with you about the How to adjust the parameters of UV laser marking machine.

Generally speaking, if the depth is not enough, you can adjust the three internal parameters such as the field lens, power and marking speed. If there is a problem of color depth, you need to adjust the frequency and its speed. Industrial production pays attention to the speed. Generally, customers care about how much can be marked in one minute, or how long it takes to mark one. In this case, try to increase the power, then increase the speed and increase the frequency to achieve the same effect of slow marking. Effect.

In the process of not confirming the parameters, first adjust a parameter according to experience, and then judge whether to increase the power or reduce the power, increase or less according to the effect parameters such as marking speed.

The direct reason for the insufficient processing depth and processing speed of the UV laser marking machine for the processing of the material is that the effective power density of the laser processing is small. For the same material, (note: not power), the optical power density refers to the power per unit area, and the calculation formula is: laser power density u003d laser power / laser spot area.
