Abstract
An arm of a coating robot is used to prevent external leakage of a high voltage. A tank is installed on a robotic arm and contains water as an actuating liquid. The water is supplied to a paint cartridge by a pump controlled by a controller. The water sent from the pump under pressure is supplied to the paint cartridge by a conduit tube. A high voltage generator and a bleeder resistor are combined with the tank such that a high voltage generated by the high voltage generator is supplied to the electrostatic paint applicator via the water. For replenishment of water to the tank is attained by relatively connecting a nozzle in communication with a water source to a main pipe. While the high voltage generator generates a high voltage, the nozzle and the main pipe are kept disconnected to maintain electrical insulation between the nozzle and the main pipe.
