A coating device includes a case, a reaction module, and a cover. The case defines a reaction cavity. Receiving plates are positioned on an inner surface of the reaction cavity. The reaction module is received in the reaction cavity and capable of being rotated in the reaction cavity. The reaction module includes an outer housing and an inner housing. The outer housing includes electric magnets and waveguides. The electric magnets are positioned around the outer housing. Waveguide channels are defined in the outer housing. Each waveguide is partially received in a corresponding waveguide channel. The inner housing is received in the outer housing. A first receiving chamber is defined between the inner and outer housings. A second receiving chamber is defined in the inner housing. The first receiving chamber communicates with the second receiving chamber and the reaction cavity. The cover covers the opening end.
