ELECTROSTATIC POWDER COATING APPARATUS, ELECTROSTATIC POWDER COATING METHOD, AND METHOD OF MANUFACTURING ARMATURE COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic powder coating apparatus which can make the temperature difference of work small while reducing the size of the apparatus.SOLUTION: The electrostatic powder coating apparatus 10 includes a carrier device 11 which sequentially carries a plurality of armature components 1 mounted on a screw shaft 21, a high-frequency heater 12 which heats the armature components 1 by a heating degreasing coil 31 to remove grease, and a coater 14 which sprays a resin powder F charged with a polarity opposite to that of the armature components 1 to the surface of the armature components 1. The electrostatic powder coating apparatus 10 also includes an overheat suppressing device 17 which suppresses overheating of the armature component 1 in the vicinity of a non-mounting part, on which the armature components 1 are not mounted, in the screw shaft 21 when the non-mounting part passes through the heating degreasing coil 31.
