Skills to improve the marking effect and speed of Laser marking machine
At present, the optical fiber Laser marking machine is mainly used for processing metal materials, and its marking content includes text, pattern, two-dimensional code, production date, etc. especially combined with the flight marking system, it can realize the processing marking of assembly line, which is widely used in the marking of beverage bottle caps, red wine bottles, battery products and other assembly line marking processing.
The factors that affect the effect and speed of laser marking are as follows
Firstly, for the fixed marking pattern, the factors affecting the marking efficiency can be divided into the equipment itself and the processing materials. Therefore, it can be concluded that the final factors affecting the marking efficiency are filling type, field mirror, galvanometer, delay time and so on.
Measures to improve marking efficiency:
1、 Choose the best of the four fillings
- Two way filling: marking efficiency, good effect.
- Loop filling: it can only be used when marking fine graphics and fonts, and its efficiency is similar to that of bow filling.
- Unidirectional filling: marking efficiency is the slowest, rarely used in actual processing
- Bow filling: marking efficiency is the highest, sometimes there will be wiring, uneven problems, marking fine graphics, fonts, there will be no such problems, so bow filling is the first choice.
The above four filling methods are different, which can be changed according to the actual marking needs. Selecting the corresponding filling method can also improve the marking efficiency. If you do not pursue the details of the marking effect, it is recommended to use bow filling, which can significantly improve the speed of marking. If you want to have both, two-way filling is a good choice.
2、 Choose a better high speed galvanometer
In general, the scanning speed of the galvanometer can reach up to 3000mm / s, but a better high-speed galvanometer can scan tens of thousands of times per second (you need to know what more zero and less zero means). In addition, when using ordinary galvanometer to mark small graphics or fonts, it is easy to deform, and the effect must be ensured by reducing the scanning speed.
3、 Suitable field mirror
The larger the focal length of the field mirror is, the larger the focus spot is. Under the same spot overlap rate, the filling line spacing can be increased, so as to improve the marking efficiency.
Note: the larger the field mirror is, the smaller the power density is. Therefore, it is necessary to increase the filling line spacing under the condition of enough marking energy.
4、 Ingenious delay setting
Different filling types are affected by different delays, so reducing the delay independent of the filling type can also improve the marking efficiency.
- Bow filling, loop filling: mainly affected by the corner delay, can reduce the light on delay, light off delay, end delay.
- Bidirectional filling and unidirectional filling: mainly affected by the on light delay and off light delay, it can reduce the corner delay and end delay.
But at the same time, we should also pay attention to that coarse graphics and fonts are less affected by the delay, so we can appropriately reduce the delay. Fine graphics and fonts are greatly affected by the delay, so the delay can be increased appropriately.
5、 Other channels
- Check the average distribution fill line.
- For rough marked graphics and fonts, "enable outline" and "walk around the edge once" can be removed.
- If the effect allows, we can increase the "jump speed" of "advanced" and reduce the "jump delay".
- Marking a wide range of graphics, properly divided into several parts to fill, can effectively reduce the jump time, improve the efficiency of marking.
The application of fiber Laser marking machine needs the participation and operation of technical personnel with certain application experience, in order to better complete the good marking effect. At the same time, the fiber Laser marking machine also needs to know the daily maintenance and cleaning, understand the basic structure and structure, in order to improve the use effect of fiber Laser marking machine.
