Daily maintenance and maintenance of the fiber laser marking machine will help protect its function and extend its life.

1. Marking machine guide rail maintenance: The fiber laser marking head is mainly composed of linear guide rail and motor. Because the guide rail directly faces the workpiece to be processed, the workpiece is The debris generated during the marking process and the dust and other impurities in the on-site environment at ordinary times are easy to adhere to the guide rail, and it is easy to cause the guide rail to wear after a long time. The guide rails should be cleaned with gasoline on a regular basis, and an appropriate amount of lubricating oil can be added after drying. This work is recommended once every two weeks. At the same time, pay attention to avoid adding oil to the timing belt in the process of cleaning and refueling.

2. Marking machine controller maintenance: Because the fiber laser marking machine is exposed to the air for a long time, it is easy to accumulate dust in the circuit board after a long time. Cleaning can easily cause a short circuit in the circuit. The cleaning method is to turn off the power of the controller, open the outer cover of the box, and use clean air to blow away the dust inside. You should also pay more attention to the dust-proof work on the outside of the box.

3. Marking equipment computer maintenance: After the computer runs for a long time, a large number of junk files will also be generated in the system. If it is not cleaned up, it will directly affect the normality of the software run. Do not add unidentified files and software to the system to avoid being affected by viruses, so as to ensure that the system works in a non-toxic environment. This job has certain requirements for the computer knowledge of the operators, and those who can use computers proficiently can do it by themselves.

5. Keep the marking head cylinder liner clean, do not allow dust, iron filings, etc. to enter the cylinder or copper sleeve, add lubricating oil before use every day; the air source is connected At this time, the two-parts will drain automatically. At this time, gas will be discharged. The marking machine will return to normal after a few minutes. Check whether the pneumatic two-parts are normal once every six months. The needle wear can be repaired. The way to remove the needle is to rotate the needle to the left. The needle and return spring can be taken out by removing the rubber gasket; oil stains and iron filings are not allowed on the travel switch; the compressed air should meet the indicators proposed in the technical requirements.

6. Other maintenance of the fiber laser marking machine: clean the appearance of the equipment and the surrounding working environment, the chiller regularly replaces the special cooling water, cleans the water tank, and ensures that the water is clean. The cooling system and the main control box are dusted, and the beam expander and the all-reflection lens are wiped with lens cleaning paper dipped in more than 99.5% pure alcohol every year.
