How to maintain the vacuum coating machine

Vacuum coating machine is a very important equipment, which is widely used in electronics, optics, electroplating and other industries. However, only proper maintenance can ensure its long-term stable operation, which can not only reduce the failure rate, improve production efficiency, but also save maintenance costs. Below, I will explain in detail how to maintain the vacuum coating machine from the aspects of daily maintenance, regular maintenance and special maintenance.

1. Routine maintenance

1. The vacuum pump oil should be checked regularly to maintain normal lubrication in the pump. When the pump oil is clear and transparent, the pump is working normally. If the pump oil is found to be turbid or has solid particles or impurities, the pump oil should be replaced and the carbon deposits or foreign objects in the pump body should be cleaned.

2. Regularly clean the dust, dust and grease in the vacuum chamber and components, so as to avoid accumulation of dust and unnecessary failure caused by long-term use.

3. Clean the inner surface of the reactor. Most of the reactors can be dismantled and cleaned, while large reactors need to be cleaned in situ with cleaning agents.

4. Clean the cylinder, motor, reducer, gripper, pneumatic components, etc. inside the coating machine to provide guarantee for the normal operation of the machine.

5. Check the air leakage of the vacuum pump, refuel or update the sealing ring in time.

6. Replace damaged and excessively worn sealing rings in time to keep the sealing performance intact.

7. Regularly replace the internal consumables of the coating machine, such as ion sources, electrodes, cathodes, and external voltage sources, to ensure long-term stable operation of the equipment.

8. Check the wiring and terminals of the equipment to ensure that the wiring is tight and not loose.

2. Regular maintenance

1. Regularly check the inner wall of the cylinder to ensure that the inner wall of the cylinder is flat, so as to avoid premature wear of the sealing ring due to unbalanced load during mechanical pressing.

2. Regularly check the connectors and sealing rings of the vacuum system, and replace them in time if any problems are found.

3. Check the gas outlet near the vacuum tube, the pump tube in the middle and the air inlet far away to ensure that the valves are tightly connected to prevent gas leakage.

4. Check the heating temperature of the vacuum drying oven to ensure that the heating is in place regularly.

5. Regularly check the heater and sensor, and replace and repair in time if any problem is found.

3. Special maintenance

1. During the production process, prevent foreign matter or debris from entering the vacuum chamber to avoid contamination and damage to the surface of the components and the vacuum tube.

2. For special maintenance, maintenance should be carried out according to the frequency of equipment use and different types of work. For example, the maintenance and maintenance of ion sources should set a specific maintenance plan according to the frequency of use, at least once a month as a standard.

3. Regularly replace the sealing ring or gasket of the vacuum pump. When the equipment of the coating machine is broken or maintained, there is often no ready-made equipment in the aftermarket, or the price is relatively expensive, so more attention should be paid to maintenance.

4. When the stress of the coating machine equipment is lower than the carrying capacity, the equipment may be obviously deformed or loosened. At this time, it is necessary to reconfigure the accessories or reset the equipment in time to ensure the normal operation of the equipment.

In short, the maintenance of the vacuum coating machine is a comprehensive consideration of various factors such as emergency elimination of equipment failures and delaying the occurrence of failures. Therefore, in daily applications, corresponding effective maintenance measures and periodic operations and inspections are required. When using a vacuum coating machine, it can Continuous maintenance of equipment maintenance methods.
