A coating system includes a coating robot and an operation robot. The coating robot has a height and is mounted in a coating booth to coat a workpiece while the workpiece is conveyed in the coating booth in a conveyance direction substantially perpendicular to a height direction. The workpiece including a body and a movable part movable with respect to the body. The operation robot is disposed in the coating booth below the coating robot in the height direction. The operation robot is movable in the coating booth in the conveyance direction and is configured to move the movable part of the workpiece.

A coating system including a coating robot and a movable opener robot. The coating robot has a fixed base fixedly mounted to a coating booth, and a first arm rotatably coupled to the fixed base about a first axis substantially parallel to a conveyance direction of a workpiece that includes a body and a first movable member. The body has a body inner surface and the first movable member has a first movable member inner surface. The movable opener robot has a movable base mounted such that the movable opener robot is movable in the coating booth in the conveyance direction. The movable base is mounted below the fixed base. The movable opener robot can open the first movable member of the workpiece. The coating robot can coat the body inner surface and the first movable member inner surface when the first movable member has been opened.

A liquid dispensing device includes a body, a nozzle on an end of the body, a liquid container coupled to the body, and a piston configured to move in the body so as to control an ejection of liquid from the nozzle. The piston and the nozzle are configured to be detached from the body as an assembly.

A splash plate assembly is retained in a rotary bell cup by a barbed skirt that interfaces with an inner surface of the bell cup. The splash plate assembly includes a splash plate or deflector that is secured to the front side of an insert. The insert has barbed extensions that may form a skirt around an outer periphery thereof. The insert is snapped into the front bell opening of a bell cup, and the barbed extensions elastically deform and snap back outwardly to interface with a shoulder formed in the bell cup inner surface.

A coating system includes a coating robot and an operation robot. The coating robot has a height and is mounted in a coating booth to coat a workpiece while the workpiece is conveyed in the coating booth in a conveyance direction substantially perpendicular to a height direction along the height. The workpiece including a body and a movable part movable with respect to the body. The operation robot is disposed in the coating booth below the coating robot in the height direction. The operation robot is movable in the coating booth in the conveyance direction and is configured to move the movable part of the workpiece.

A coating system including a coating robot and a movable opener robot.
