Fiber laser, the temperature is too high, the marking can t be marked, is there a fault?

The laser is a laser marking machine.

In the daily work of the laser marking machine, customers often encounter the situation that the laser marking machine cannot be marked and the laser temperature is too high, what is the reason for this? And can it solve this kind of problem?

Under normal circumstances, the laser generates heat when it is working, which causes the working medium of the laser to heat up, which affects the wavelength and output power of the laser.

Mode stability and other features. Lasers usually operate at a constant temperature, and the workshop is air-conditioned, so refrigeration or thermostatic components are required to ensure that the laser active medium is always at a constant temperature. Fiber lasers.

It is a new generation of laser, which has no requirements for the working environment, does not require air conditioning, and does not need water cooling, which is very convenient to use.

When the laser temperature is too high, it means that the laser temperature is too high, and the power supply will be automatically turned off, please check whether the temperature of the external working environment and the water cooler (air cooling system) is between 20 and 22 degrees, when the working temperature is within this range, the error message will no longer be displayed.

Note: For the state of overtemperature, the equipment has a protective device, if the laser temperature exceeds 35 degrees, it will automatically stop the light, and a warning will appear, if the temperature drops to 34 degrees, you can turn on the laser power again, if the laser temperature is too high, do not use the equipment for the time being, you can also turn off all the power of the laser marking machine, rest for a few minutes and then turn it on, at this time it will resume normal work, if the temperature of the laser is too high, please contact the laser manufacturer for after-sales maintenance.

You can take a look at the output voltage of the open optical power supply that supplies power to the laser.

Hello, glad to answer for you. There are several common fault solutions for fiber laser marking machines. 1. What should I do if the fiber laser marking machine can't print If F2 can't mark, it may be a machine failure.

1. The software laser type is set incorrectly; 2. The optical path is wrong; 3. The laser power supply is not energized or damaged; 4. The control signal line is broken or the plug is loose or the control card is broken; 5. The laser is broken. Solution: If F2 can be played, you press F3, then click on the port, see the mathematics behind the start marking, adjust it, 0-15 can be tried one by one, different brands of machines are different.

Second, what to do if the focus of the laser marking machine is offset, because each focusing lens corresponds to the range of the depth of focus of the loose banquet, and the use of off-focus methods will easily lead to a large range of marking patterns, the edge is at the critical point of the depth of focus or out of the depth of focus range, so it is easy to have uneven results. Therefore, the method of bias marking is to think about the problem of laser energy. Third, the identification pattern of the laser marking machine is not clear 1, solution:

Check whether the thickness of the molded plate is uniform, whether the molding pressure is too small, whether the temperature is too low, and whether the accuracy of the machine is reduced. 2. Key points of process control: the thickness error of the molded plate should be controlled within 0 o01mm, and the hardness should be kept at 230-280n mm.

Because the hologram is molded by applying pressure to the molded rollers to create interference fringes, if the hardness of the molded plate is not enough, the internal stress will deform or damage the molded plate during the embossing process. Fourth, the laser marking machine light is weak 1, the focal length is not adjusted well, and the focal length is readjusted. 2. If the CW method of the marking software is not selected, the light will be very weak, so choose the CW method.

3. The cavity, total mirror, semi-reflector and beam expander are not adjusted and re-adjusted. 4. The laser does not hit the midpoint of the galvanometer, or the lens of the galvanometer is scratched. Readjust the optical path, or swap the galvanometer.

Fifth, the laser marking machine can not emit light 1, the board is damaged, and the board is replaced. 2. If the laser power supply is broken, replace the laser power supply. 3. The optical path is not adjusted well, and the optical path is re-adjusted.

4. Computer mining, such as manipulating the system or computer obstruction, reinstalling the system or replacing the computer. 5. The signal connection between the board and the driver is open, and it is replaced or re-soldered. Hope it helps!

How to adjust the fiber temperature of the laser marking machine, hello! 1. For overheating, the laser is equipped with a bright-keeping dust protection device. If the laser temperature exceeds 35 degrees, it will automatically stop emitting light and a warning prompt will appear.

2. If the temperature drops to 34 degrees Jingzen, you can restart the laser power supply. If the laser temperature is too high, please do not use the device for a while. 3. You can also turn off all the power of the laser marking machine, let it stand for a few minutes, and then turn it on again.

At this point, it will return to normal work. 4. If the temperature of the fiber laser is too high, it means that the laser may be damaged and needs to be replaced, please contact the purchasing manufacturer. Hope it helps!

Hello, sorry to keep you waiting! Adjustment method and daily maintenance of laser marking machine 1Turn on the machine in the normal boot order, note that the chiller must be turned on, and wait for the real-time preparation temperature of the chiller to be consistent with the set temperature before proceeding to the next step.

2.Disassemble the protective cover of the laser marking machine, and pay attention not to rub it; Turn off the laser and Q switching power supply according to the normal shutdown method. 3.

Use a dimming frequency multiplier or white paper to observe the red light output and feedback at this time, and it is advisable to use the red light indicator screen to have the brightest spot with the most rolling circle. If there are multiple red light spots, adjust the red light indicator to each adjustment nut of the beam expander in turn until the requirements are met. 4.

Turn on the laser reflex power, adjust the current to the range of 14 15A, it is best not to exceed 15A, and use the dimming frequency multiplier to observe whether the laser output is the roundest and brightest spot in front of the laser. 5.The frequency multiplier is placed behind the beam expander to observe for laser output.

If not, slowly adjust each adjustment nut in order until there is the brightest and roundest spot.

Hello, dear, very happy to answer for you! Here's the answer, check it out! The first thing to understand is that the working principle of the laser marking machine is to use a laser light source to focus the laser rays on the surface of the object to form a focal point, and by changing the position of the focus point, it can be engraved or depicted with dyes for different materials without loss.

Due to the different properties of different color mold fiber materials, some materials will produce different absorption under different wavelengths of laser rays, so these materials may not be able to perform the change of the surface of the material under some wavelengths of laser, so that different materials cannot be engraved, cut or depicted by dye, resulting in the laser marking machine can not mark. Your questions have been answered! I hope to be able to help you, if there is something wrong, you can continue to consult with God of Rent, and bear with me!

If the fiber laser marking machine does not shine, we must first investigate the best problem.

If the fault phenomenon is: the light output is abnormal, on the high-voltage side, the ammeter is connected in series, and the ammeter can be seen to be abnormal, either there is a current for a long time, or it comes and goes, and sometimes it is not controlled.

Cause of failure: The main reason is the wrong choice of laser type, the connection of the motherboard, power supply or control line, and the failure of the cooling water circulation system.

So how to deal with it:

1. In the parameter setting, see whether the laser type is correct, which is the main cause of continuous luminescence failure.

2. Pull the control line of Jiurui to see if the control line is loose. The connection is unreliable.

3. Remove the control cable (nine-core wire) on the power supply, and press the point shot button of the laser power supply to analyze whether the power supply or the motherboard is faulty.

4. If the spot shot is normal, it means that the power supply is not faulty.

5. The spot shot is also abnormal, indicating that there is a problem with the power supply.

6. When the power supply is normal, connect the control line, use a multimeter to measure the switch control pin on the terminal board, when it does not emit light, the normal voltage is above 4 volts, and below 3 volts, the output of the motherboard is abnormal; When emitting light, the voltage of the pin should be below 2 volts, and the output above volts is abnormal.

7. Check whether the water cycle is normal, whether the water flow is coming and going, and whether there is a problem with the water protector.

The display temperature of the semiconductor laser marking machine is too high, and it should be said that the display temperature of the chiller of the semiconductor laser marking machine is too high. We do special chillers, laser marking machines use more of our machines, this situation is sometimes seen. If you are using a special chiller, you can have the following treatment methods:

1.First open the dust filter of the semiconductor laser marking machine, the semiconductor laser marking machine, the chiller, see if there is a lot of dust accumulation, and clean it.

2.See if the fan of the diode laser marking machine chiller is faulty3Restore the temperature controller of the diode laser marking machine chiller to the factory value of 4

If none of the above works, it may be that there is a problem with the compressor or compressor of the semiconductor laser marking machine chiller or the capacitance of the compressor, and it is recommended to contact the manufacturer to deal with it.

Then turn off the machine first and let it cool down for a period of time, because in summer, the indoor temperature and humidity are already high, so the temperature of the marking machine is easy to rise, it is best not to work continuously for a long time, and no matter how good the marking machine is, it will reduce its life.

Really can't add cold pure water to the chiller, this is a faster way, I used to stay in the company is to have one, I will add cool pure water, soon the temperature will drop, open the lid of the chiller, to prevent the temperature from too high, if stuffy easy to make the water temperature rise, I hope you can solve the problem as soon as possible, good luck.
