For most companies, fiber laser marking machine is a relatively common laser equipment in the market. It is characterized by reliable structure, small size, low power consumption, high beam quality, and high laser repetition frequency. It is widely used, so for companies that are first exposed to fiber laser marking machines, how to solve these parameter adjustment problems?
First of all, we must understand the power of the laser. The understanding of the power is very important for the initial commissioning of the fiber laser marking machine, because the greater the output power is adjusted, the greater the laser output energy and the easier it is to drill. Moreover, the price of lasers in the market is also fixed. They are all determined by power. Lasers are divided into two categories: continuous fiber lasers and pulsed fiber lasers.
Continuous fiber laser: 5W, 10W, 20W to 400W, 4000W.
Pulsed fiber laser: 10W, 15W, 20W, 25W, 30W to 50W.
After we understand the power of the laser of the fiber laser marking machine, we must be relatively vague about the parameter setting of the marking machine, and it is also a difficult part in the operation process, so let’s take a look at the various parameters of the fiber laser marking machine adjust.
Parameter adjustment of fiber laser marking machine
1. Marking power. It may not be felt by the naked eye. Generally, the default parameter is 50% output power. The greater the output power adjustment, the greater the laser output energy, but the output power adjustment should be selected according to your actual needs, because the output energy is too large, in the parameter setting, the power is adjusted by a percentage, which affects the laser Hit deeper.
2. If the marking frequency is high. The higher the marking frequency, the denser the laser dots and the smoother the marking.
3. Marking speed. Because the overall marking speed is not only adjusted by the speed parameter, the faster the speed, the faster the marking speed.
The faster the speed, the fewer times the laser hits the same place.
Slow speed is more conducive to depth, but it is not that the slower the speed, the better the depth. Because the speed of marking is too slow, the material produced by the laser will accumulate on the surface of the material. This refers to the moving speed of the laser.
4. Filling is mainly used for black alumina: one-way filling, two-way filling, mainly used in unrelated closed graphics.
5. Finally, the pulse width. Pulse width refers to the duration of a pulse. The general fiber laser marking machine does not have the function of adjusting the pulse width. What are the advantages of the pulse width adjustable fiber laser marking machine? Marking frequency, the number of pulses per unit time is called the marking frequency of the fiber laser marking machine .
After looking at how to adjust the various parameters of the fiber laser marking machine mentioned above, you may have a vague concept of the fiber laser marking machine. See how to perform the specific operation below.
1. Select the current pen number.
2. Generally, if the default parameter is not selected, it must be unchecked in the Use default parameter selection box.
3. In the parameters, except for speed (mm/sec), power (%), frequency (khz), other parameters are unchanged.
4. Speed: generally adjusted within 100mm/s~500mm/s, the slower the speed, the longer the marking time, the larger the output energy, the deeper and the heavier the marking.
5. Power: Adjust between 10% and 90%. The greater the hardness of the corresponding printed material, the higher the adjustment power.
6. Frequency: adjust within 20 khz~80 khz, increase the frequency, the marking will become lighter and lighter. On the contrary, reduce the frequency, the marking becomes deeper and heavier.
Is the above operation very easy? Even if we are not very proficient in the operation, we will get satisfactory laser marking effect if we use slow speed, high frequency, power 50%-60%, moderate pulse width to set.
Fiber laser marking machine also pays great attention to maintenance in daily use, not only to extend the use period, but also to avoid safety hazards. Next, I will share with you the daily maintenance and precautions of fiber laser marking machine.
1. When the fiber laser marking machine is not working, cut off the power supply of the marking machine and the computer.
2. No longer use laser equipment, cover the field lens lens to prevent dust from polluting the optical lens.
3. Non-professionals, do not overhaul when the machine is turned on to avoid electric shock accidents.
4. Any failure of this machine should immediately cut off the power supply.
5. When the equipment is used for a long time, the dust in the air will be adsorbed on the lower end surface of the focusing lens. The lighter ones will reduce the power of the laser and affect the marking effect; the heavy ones will cause the optical lens to absorb heat and overheat and cause explosion.
- If the surface of the focusing lens is contaminated, you should remove the focusing lens to clean the lower end surface. The cleaning method is to mix absolute ethanol (analytical grade) and ether (analytical grade) in a ratio of 3:1 and use a long-fiber cotton swab. Or the lens paper invades the mixed solution, gently scrub the lower end surface of the focusing lens, and change the cotton swab or lens paper every time you wipe the surface. 7. During the working process of the marking machine, do not move the marking machine to avoid damage to the machine. 8. Do not cover or place other items on the marking machine, so as not to affect the heat dissipation effect of the machine.
The above is all about the parameter settings for the initial commissioning of the fiber laser marking machine, I hope it will help you. The widespread use of fiber laser marking machines will continue to grow in the next few years.
