The development of science and technology has promoted the process of modernization, and laser marking machines have become a hot industry. It has been widely used in various industries. Today, we will analyze the service life of the CO2 laser marking machine and how to prolong the life time of it.
The following knowledge points are listed below:
How long a CO2 laser marking machine can last
How to prolong the life time of CO2 laser marking machine
The characteristic of CO2 laser is that it has rich spectrum. There are many 10μm near the line. The optical output power is large, the line width is narrow, and the operation is stable. The energy conversion efficiency can reach 30-40%, and the service life of CO2 laser light source is generally 2w hours.
You should pay special attention to the items bellow when using the laser tube to extend the life of the CO2 laser engraving machine. This will give you a better understanding of laser tool maintenance.
The main contents are as follows:
(1) First, connect the chiller or water pump to the laser tube properly, and keep the cooling water temperature in the range of 12-30 degrees
Please connect the cooling water to the laser tube, and ensure that the water at the laser tube mouth is down and up to help the water flow smoothly. Adjust the position of the water outlet pipe, make sure that the cooling water of the full condenser is not its own bubble pipe, and then turn on the power. Requirement: The cooling water in the laser marking machine should use soft water, and always pay attention to the cooling water temperature, the water temperature should be controlled within the range of 12-30 degrees. It should not be too high or too low, especially in summer. Once the water temperature is too high, please replace the cooling water in time, otherwise it will damage the laser tube. In winter, the cooling water cannot freeze, especially after the laser is turned off, the cooling water may not be allowed to stay in the laser tube, so as not to cause the cooling water to freeze and crack.
(2) Second, the cooling water flow rate is maintained at 2L-4L / min, and the laser tube remains full.
The two support points of the co2 laser tube should be at 1/4 of the total length of the laser tube to ensure that the cooling water flow rate is 2L-4L / min; otherwise, the working accuracy will deteriorate, it is easy to split the laser spot and reduce the power. The cooling water outlet in the water tank must be covered with water, otherwise the laser tube is empty every time, which is easy to damage the laser tube.
(3) Third, protect the laser tube outlet from pollution
Carefully protect the mouth of the laser output of the laser marking machine and avoid the process (including the process of debugging the optical path). The outer surface.
(4) Fourth, properly adjust the laser tube to achieve the best output
During the debugging process, adjust the laser tube anchor or rotate the direction of the laser tube to achieve the best output effect, and then fix the laser tube.
(5) Fifth, keep the vicinity of high-voltage electrodes clean, away from dry, high-voltage metals
Ensure that there is no dust accumulation near the high-voltage electrode. Keep it dry. Keep the high-voltage metal away from the end surface as much as possible to prevent high-voltage ignition discharge.
(6) Sixth, avoid the formation of scale in the cooling tube of the laser marking machine.
During use, scale can be formed in the cooling pipe to avoid blockage of cooling water and change in cooling effect. Once found, the condenser can be cleaned with 20% dilute hydrochloric acid to remove scale.
So after reading this article you should know how to maintain the CO2 laser marking machine now. We also provide laser welding machine, UV laser marking machine.
