When maintaining the coating machine, it is important to pay attention to the following key points:

1. Regular inspection:

Regularly inspect all components of the coating machine, including the vacuum pump, power supply, control panel, vacuum chamber, valves, etc., to ensure that they are in good working condition.

2. Cleaning and lubrication:

Clean the dust and dirt inside and outside the equipment, especially the vacuum chamber and optical components.

Regularly lubricate moving parts and mechanical components to reduce wear and friction.

3. Vacuum system maintenance:

Regularly check the sealing of the vacuum system to ensure there are no leaks.

Maintain the vacuum pump, including replacing pump oil, cleaning the inside of the pump, checking the performance of the pump, etc.

4. Electrical system inspection:

Check if the electrical connections are secure and ensure there is no looseness or corrosion.

Check the circuit board and electrical components to ensure they are working properly.

5. Maintenance of cooling system:

If the coating machine is equipped with a water cooling system, it is necessary to regularly check the flow of cooling water, clean the cooling pipes, and ensure the cooling effect.

6. Maintenance of optical components:

Regularly clean optical components to avoid dust and dirt affecting coating quality.

7. Spare parts reserve:

Reserve some spare parts for vulnerable and critical components so that they can be quickly replaced when needed.

8. Records and documents:

Record the time and content of each maintenance, as well as any identified issues and solutions.

Save all maintenance and operation documents for easy tracking and reference.

9. Professional maintenance:

For complex maintenance work, such as major repairs of vacuum pumps or calibration of optical components, professional maintenance personnel should be contacted for assistance.

10. Safety measures:

During maintenance, make sure to disconnect the power supply to prevent electric shock accidents.

Use appropriate personal protective equipment such as gloves, glasses, masks, etc.

By maintaining the above key points, the long-term stable operation and coating quality of the coating machine can be ensured. In the actual maintenance process, the manufacturer's maintenance guidelines and recommendations, as well as relevant safety regulations and standards, should be followed.
