In today's society, fiber laser marking machine is mainly used for processing metal materials. Its marking content includes text, pattern, two-dimensional code, production date, etc., especially
in combination with the flying marking system, which can realize the processing and marking in an assembly line. It is widely used in the marking of beverage bottle caps, red wine bottles, and
battery products.
Factors affecting the effect and speed of laser marking:
First of all, for the fixed marking pattern, the factors that affect the marking efficiency can be divided into the equipment itself and the processing material. Therefore, it can be concluded
that the factors such as filling type, field lens, galvanometer, and time delay that ultimately affect marking efficiency can be obtained.
Measures to improve marking efficiency:
One or four fillings to choose the most suitable;
1. Two-way filling: The marking efficiency is high, and the effect is good.
2. Shape filling: It is only used when marking thin graphics and fonts, and the efficiency is almost the same as that of bow filling.
3. One-way filling: The marking efficiency is the slowest, and it is rarely used in actual processing.
4. Bow-shaped filling: The marking efficiency is the highest, and sometimes there will be problems with connection lines and unevenness. When marking thin graphics and fonts, the above problems will not
occur, so bow-shaped filling is the first choice.
The above four filling methods are different and can be changed according to actual marking requirements. Choosing the corresponding filling method can also improve marking efficiency. If you do not pursue
the marking effect of details, it is recommended to use bow filling to significantly increase the marking speed. If you want to have both, two-way filling is a good choice.
Second, choose a better high-speed galvanometer;
Under normal circumstances, 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 have to know what
more zero and less zero mean). In addition, when using ordinary galvanometers to mark small graphics or fonts, deformation is easy to occur, and the scanning speed must be reduced to ensure the effect.
Three, suitable field lens;
The larger the focal length of the field lens, the larger the focused spot. Under the same spot overlap rate, the filling line spacing can be increased, thereby improving the marking efficiency.
Remarks: The larger the field lens, the smaller the power density. Therefore, it is necessary to increase the filling line spacing while ensuring sufficient marking energy.
Four, cleverly set the delay;
Different filling types are affected by different delays, so reducing delays that are not related to the filling type can also improve marking efficiency.
1. Bow-shaped filling and back-shaped filling: Mainly affected by the corner delay, it can reduce the turn-on delay, turn-off delay, and end delay.
2. Two-way filling and one-way filling: Mainly affected by the light on delay and off delay, it can reduce the corner delay and end delay.
But at the same time, please note that thick graphics and fonts are less affected by the delay, and the delay can be appropriately reduced. Thin graphics and fonts are greatly affected by the delay,
and the delay can be increased appropriately.
Five. Other channels;
1. Check "Evenly distribute fill lines".
2. For marking thick graphics and fonts, you can remove the "enable outline" and "walk once".
3. If the effect permits, you can increase the "jump speed" of the "advanced" and reduce the "jump delay".
4. Marking a large range of graphics, properly divided into several parts to fill, can effectively reduce the jump time and improve the efficiency of marking.
The application of fiber laser marking machine requires technical personnel with certain application experience to participate in the operation 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, and understand the basic structure and The structure can improve the use effect of the fiber
laser marking machine.
