Abstract:
1. An electrostatic coating system including an electrostatic atomizer which has a high voltage application electrode provided at a distal end thereof to be supplied with a high voltage, and generates an electrostatic field between the high voltage application electrode and a work to electrically charge a paint and deposit the electrically charged paint onto the work due to electrical absorption, comprising: an electrically conductive end plate disposed at a rear end of the electrostatic atomizer apart from the high voltage application electrode thereof, wherein high voltage leak caused by contamination of outer surfaces of the electrostatic atomizer is detected via the end plate, wherein the electrostatic atomizer is supplied with power via a conductive connector fixed to the end plate, and high voltage leak caused by contamination of outer surfaces of the electrostatic atomizer is detected through a first wire connected to the conductive connector, wherein the electrostatic coating system further comprises a coating robot, and the electrostatic atomizer is attached to a distal end of an arm of the coating robot, wherein the electrostatic coating system further comprises a paint cartridge removably attached to the electrostatic atomizer, and paint in the paint cartridge is discharged from the electrostatic atomizer, wherein a conductive ring is provided in contact with an outer marginal portion of the end plate to extend the end plate toward a distal end of the electrostatic atomizer.
