The service life and maintenance method of optical fiber marking machine

One hundred thousand hours, this is the average output time of the laser of the optical fiber Laser marking machine. What is this concept? We can compare the horizontal and the vertical. So in theory how many years can a fiber optic laser marking machine work you should be able to figure that out. Of course, this is only a theoretical value. In fact, the service life of fiber laser marking machine is affected by many factors. On average, a fiber laser can take five or six years.

Now on the market there are several kinds of types of laser marking machine, in addition to optical fiber laser marking closed, and CO2 laser marking machine, laser marking machine, uv and semiconductor laser marking machine, go back and YAG laser marking machine, etc. Among these machines, optical fiber laser marking machines generally have the longest working life, usually up to 100,000 hours. The working life of semiconductor laser marking machine and CO2 laser marking machine is about 10,000 to 20,000 hours.

Why is the optical fiber laser marking machine the longest working life? This is determined by the performance advantages of the fiber laser itself. Fiber laser electro-optical conversion efficiency is high, can greatly save power consumption, reduce operating costs, to achieve the highest production efficiency, and its working substance is crystal, can support long motivation, the laser oscillation in optical fiber, less heat production, air cooling, with no cold water machine, and do not need to frequently change jobs like gas laser gas, material consumption... Based on these factors and correct maintenance methods, the working life of optical fiber laser marking machine is very long.

Maintenance and maintenance is the only way to maintain, improve performance, precision, save money, improve efficiency and create more economic benefits for enterprises. The following summarizes a series of optical fiber marking machine maintenance specific methods.

1) when the machine is not working, the marking machine and computer power should be cut off.
2) when the machine is not working, cover the lens of field lens to prevent dust from contaminating the optical lens.
3) when the machine is working, the circuit is in a high voltage state. Non-professional personnel should not repair it when starting up to avoid electric shock.
4) power should be cut off immediately if there is any fault in the machine.
5) when the equipment is used for a long time, dust in the air will be adsorbed on the surface of the lower end of the focusing mirror, and light will reduce the power of the laser and affect the marking effect; Heavy causes the optical lens to absorb too much heat and burst. When the marking effect is not good, the surface of the focusing mirror should be carefully checked for contamination.
If the surface of the focusing mirror is contaminated, remove the focusing mirror and clean the bottom surface.
Special care should be taken to remove the focusing mirror. Also, don't touch the focusing mirror with your hands or other objects.
Cleaning method is ethanol (analysis) and diethyl ether (analysis), according to the proportion of 3:1, mixed with long fiber cotton swabs or lens paper into mixture, and gently scrub focus lens surface of bottom, each side brush try, must replace a swab or lens paper.
6) during the work of the marking machine, the marking machine shall not be moved to avoid damaging the machine.
7) do not cover the heap or put other items on the marking machine to avoid affecting the cooling effect of the machine.
8) dust should be cleaned frequently to keep the machine dry and clean. Clean the dust from inside to outside. Pay attention to laser and electricity
The brain outlet dust, do not clear into the laser and computer box.
9) the working environment of the machine must be kept dry and ventilated.
