[0002] In the process of preparing a precision surface coating, it is necessary to ensure the density of the ion source inside the coating chamber. The filament ion source is the main component that generates ion sources inside the coating chamber. At present, the current of the filament ion source is increased to achieve the required ion source density. However, the filament ion source is easily damaged and has a short service life due to the frequent flow of different currents.
[0003] Therefore, there is a need to provide a coating equipment with a long service life for the filament ion source to solve the above problems. Utility Model Content

Every two filament ion source modules are arranged in a group. Both ends of each group of filament ion sources are connected to a power supply circuit, and one end of the power supply circuit is connected to an on / off control module.
[0007] Adaptively select one filament ion source module, two filament ion source modules, three filament ion source modules, or all filament ion source modules, and power them on to supply ion sources, forming an adaptive and rapidly changeable ion source supply structure. This results in a coating structure that does not require frequent flow of different currents and improves the service life of the filament ion source.
[0008] Furthermore, the filament ion source module includes a filament protective housing, and a filament is disposed inside the filament protective housing.
[0009] Furthermore, the filament is a tungsten wire with a diameter of 1mm.

When the electromagnet is energized or de-energized, it controls whether the corresponding closed end is attracted or not, and the closed end is connected to or moved away from the corresponding docking end, forming a filament on / off control structure.
[0013] Furthermore, the electromagnet connection has a resilient return element.
[0014] Furthermore, the elastic restoring element is composed of a tension spring.
[0015] Compared with the prior art, this invention can provide different numbers of filaments for ion source supply to accommodate different ion source densities, without the need to adjust the current passing through the filaments, thus effectively improving the service life of the filament ion source.
