Abstract
A cover for a robot which includes an electrostatic spray gun with a nozzle which sprays charged material. The cover includes an insulating layer adapted to generally surround the robot except at an aperture where the nozzle extends from the cover. The cover also includes a conductor on the insulating layer near the aperture and spaced apart from the robot. A charge source provides an electric charge to the conductor.
Claims22
A method of painting comprising:
- placing a conductor on a cover, the cover at least partially surrounding a robot and including an aperture, the robot including an electrostatic spray gun including a nozzle extending from the aperture and spraying an electrically charged material onto an object, the placing further comprising placing the conductor near the aperture and spaced apart from the nozzle;
- and
- charging the conductor with the same polarity charge as the material spraying from the spray gun whereby an electric field associated with the spray gun is enhanced, a transfer efficiency of the spray gun is improved, and an overspray of the spray gun is reduced.
A cover for a robot comprising:
- an insulator adapted to at least partially surround the robot, the robot including an electrostatic spray gun including a nozzle to spray an electrically charged material on to an object, the insulator including an aperture to allow the nozzle to extend from the cover;
- a conductor coupled to the insulator near the aperture and to be spaced apart from the robot;
- and
- a charge source to electrically charge the conductor.

An industrial material spraying robot, comprising:
- a spray gun including a nozzle to spray material to be electrically charged;
- an insulating cover at least partially surrounding the robot and including an aperture to allow the nozzle to extend from the aperture;
- a conductor spaced apart from the robot and on the cover;
- and
- an electric charge source coupled to the conductor to charge the conductor with a charge opposite that of the material to be sprayed.
