  • Electrostatic coating apparatus
    Patent number: 7963244
    Abstract: An electrostatic coating apparatus for coating an object includes a base module, a nozzle, an electric field generator and a power supply. The object is mounted on the base module. The nozzle receives gas and liquid and ejects the gas and the liquid. The electric field generator mounted on the base module generates an electric field. The power supply has a first pole electrically connected to a first pole of the electric field generator, and a second pole electrically connected to the object and a second pole of the electric field generator such that the electric field is generated in the electric field generator and the atomized liquid passing through the electric field generator is charged and absorbed onto the object to form a coating layer on the object.
