1. A coating device for applying a coating to a member to be coated, comprising:
a roller assembly, comprising a first spool and a second spool that are spaced apart from each other, the first spool being configured to release the member to be coated, and the second spool being configured to roll up the member to be coated after being coated with the coating;
a coating assembly, arranged at a downstream position of the first spool and an upstream position of the second spool, the coating assembly comprising an electrostatic roller set and an electrostatic rod, the electrostatic roller set being at least partially rotatable and configured to electrostatically adsorb a powder, and the electrostatic rod being configured to provide an electrostatic adsorption force to the powder on the electrostatic roller set, so that the powder is peeled off from the electrostatic roller set and laid on the member to be coated; and
a composite assembly, arranged at a downstream position of the coating assembly, the composite assembly being configured to connect the powder that is laid on the member to be coated with the member to be coated to form the coating connected to the member to be coated.
