Laser marking machine daily maintenance and common troubleshooting


Author: Correct Pack -Laser Marking Machine Manufacturer

Many people will ask you how long this marking machine can be used. The equipment needs maintenance. It does not mean that it can be used for as long as it is used. If the maintenance is not good, it can be used for a few years or it will be broken in a few months. Co2 laser The marking machine has a set of comprehensive maintenance methods, so that the service life will be closer to the theoretical service life. Co2 laser laser marking machine is also called carbon dioxide laser marking machine. There are two types, one is glass tube and metal tube. In terms of service life, the service life of metal tube is longer, but the maintenance method is roughly the same. All need to pay attention to temperature and air environment and so on. The Co2 laser marking machine needs to pay attention to the small details of maintenance:.

1. Working temperature requirements. The Co2 laser marking machine works at a suitable temperature and cannot be placed outside, especially in winter. The general working environment temperature is between 5°C and 30°C. Second, access to the power supply voltage requirements.

The power supply requirement is applicable to the common voltage of 220v, and the ground wire needs to be connected to avoid accidents, and the air quality is required. Three, air quality requirements. The dust-free workshop of the laser marking machine is the best, but it is not the dust-free workshop. Pay attention to the air quality. When the air quality is poor, pay attention to regularly clean the dust inside the machine and the lens to avoid affecting the marking effect. The processing place is equipped with smoking. The machine not only protects the operator from inhaling harmful gas, but also protects the machine from inhaling gas from adhering to the surface and affecting its service life.

Fourth, ventilation and heat dissipation requirements. Co2 laser marking machine has two types: cooling and water cooling. For cooling, pay attention to whether the cooling effect of the fan can be satisfied after using for a period of time. For water cooling, pay attention to the water level of the water tank. Always pay attention to the dynamics of the marking machine during use. It is recommended to turn off the laser temperature alarm first. Check the reason, try to make people leave, and the laser processing is turned off. Fifth, maintenance requirements.

The laser marking machine not only has requirements for the environment during use, but also needs to be maintained after a period of time, which can prolong the service life of the machine. The maintenance is generally 3-6 months, which is determined according to the use environment and use time Maintenance maintenance time, maintenance scope, inspection of all aspects of the laser, dust cleaning, galvanometer cleaning, internal cleaning of the marking machine, inspection of the UV laser marking machine and lines, etc. How to solve this problem if the marking depth cannot reach the ideal depth:. First, adjust the laser power first, and then proceed to the next step if the power has not been resolved.

Second, adjust the focal length to a reasonable position. The height of the product is different, and both the planar and non-planar focal lengths need to be readjusted. Three, the marking speed is too fast, slow down the speed. There may be other reasons for the adjustment parameters not meeting the requirements. We should analyze the problem from other aspects.

First, there may be dust on the surface of the lens after it has been used for a long time, so pay attention to check it. Second, the power supply has been used for a long time, and whether it is still in a stable state. Third, whether the position and direction of the beam expansion are accurate.

Fourth, whether the optical path adjustment is accurate or not, the optical path will also affect the marking depth of the marking machine. Fifth, the laser has been used for a long time, and the beam becomes weak. The laser needs to be replaced, or the continuous marking check box should be selected. The marked graphics are not standard or very different. This is generally a problem with the galvanometer. For example, a standard square is printed into a trapezoid or the like when it is marked, or it is directly printed out by an IC automatic laser marking machine. This method may be a problem with the galvanometer. If the replacement of the galvanometer does not meet the requirements, it may be related to the concave-convex surface of the marked item. If necessary, the visual positioning effect will be better. The solution can be to correct the signal of the galvanometer. If hardware calibration still can't solve it, then choose software calibration.

The lines printed by the laser marking machine are dotted lines. How to solve this method:. First, the signal is not well connected, resulting in unstable transmission. Second, there may be a problem with the signal cable.

Third, whether the card insertion position is accurate, or it may be caused by incorrectness. Fourth, the signal may be interfered, so keep the source of interference away from the marking machine. Fifth, the power output is unstable, causing disturbing marking.

There are various messy faults during the use of laser marking machines. The common faults are not these, far more than the above, and the text description is limited, so I will not describe them one by one here. Please ask professionals to solve it. Non-professionals should not disassemble the machine to avoid accidents or cause more serious failures of the machine. Zhuhai Correct Pack is a well-known laser equipment manufacturer in China.
