ROBOTIC APPARATUS FOR PAINTING

摘要

A painting robot outer arm (35) includes a non-conductive housing (35a) mounting a color changer (42) on the outside and a paint canister (47) on the inside connected by an isolating paint transfer line (48). The paint canister (47) is releasably attached to a piston ram (50) and a drive motor (52) by a quick disconnect coupling (56). The paint supply (41) is isolated from the applied high voltage by cleaning and drying the transfer line (48). The rate of filling of the paint canister (47) can be controlled in response to sensed torque applied by the drive motor (52) moving a piston in the canister.
