Laser marking is the use of laser beams to make permanent marks on the surface of various materials. It has been widely used in various industries, especially in some occasions that require finer and higher precision. In order to ensure the smooth operation of the laser marking machine, we can properly understand some of the use of laser marking machine tips or maintenance tips during operation, which can make the laser marking machine have a longer service life and run more stable. Let's share with you Leapion Laser below.
1. The power of the laser marking machine can be adjusted in percent in the parameters, and the general parameters are 50% by default. The greater the adjusted power, the greater the laser energy output, and the simpler the marking depth.
However, the output power must be determined according to its own material. It is not that the higher the power, the better, as long as it can meet its own requirements, and a machine that works under high load for a long time can cause great damage to the laser.
2. The temperature of the laser marking machine should not be too high in the environment in which it is used, which will affect the heat dissipation of the laser marking machine, thereby affecting its service life.
3. The environment where the laser marking machine is used should not be humid. The humid environment will affect the circuit and also affect the marking effect of the machine.
4. Change the field lens of the laser marking machine into a small-range field lens. After the conversion, the marking depth will be deeper. For example, the current semiconductor laser marking machine can be equipped with a 110 field lens. With a field lens of 50, the total laser energy and lettering depth will reach about twice the previous effect.
5. The lens used by the laser marking machine should be checked regularly. Due to the influence of laser energy radiation during use, the lens frame will heat up during use, which will easily cause the surface of the lens frame to rust, which will affect the laser marking. The service life of the machine equipment.
6. Direct exposure of laser radiation can cause human injury. Therefore, the place where the equipment is used needs to be equipped with fire-fighting equipment. It is strictly forbidden to stack flammable and explosive materials on the workbench and around the equipment. At the same time, it must be well ventilated. Non-professional operators are prohibited from approaching the equipment.
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. In addition, when using ordinary galvanometers to mark small graphics or fonts, deformation is prone to occur, and the scanning speed must be reduced to ensure the effect.
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.
Different filling types are affected by different delays, so reducing delays that are not related to the filling type can also improve marking efficiency.
Bow fill and round fill: Mainly affected by the corner delay, it can reduce the turn-on delay, turn-off delay, and end delay.
Two-way filling and one-way filling: Mainly affected by the light-on delay and light-off delay, it can reduce the corner delay and end delay.
But at the same time, it should be noted 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.
Two-way filling: The marking efficiency is high, and the effect is good.
Shape filling: It is only used when marking thin graphics and fonts, and the efficiency is similar to that of bow filling.
One-way filling: the slowest marking efficiency, rarely used in actual processing.
Bow-shaped filling: the highest marking efficiency, 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.
