Abstract
Rotating applicators are disclosed. A disclosed example apparatus includes an inlet to receive a surface coating to be applied to a surface of a workpiece, a shaft having a fluid channel extending therethrough, where the fluid channel is in fluid communication with the inlet, and an applicator coupled to an end of the shaft, where the applicator has an opening in fluid communication with the fluid channel. The apparatus also includes a pump to cause the surface coating to flow from the inlet to the opening, and a motor to rotate the shaft while the applicator dispenses the surface coating from the opening.
Claims20
An apparatus comprising:
- an inlet to receive a surface coating to be applied to a surface of a workpiece;
- a shaft having a fluid channel extending therethrough, the fluid channel in fluid communication with the inlet;
- an applicator coupled to an end of the shaft, the applicator having first and second openings in fluid communication with the fluid channel, the first and second openings on an applicator surface at a first side of the applicator opposite from a second side of the applicator that is proximate the shaft;
- a backing pad to support the applicator, the backing pad including first and second backing pad channels fluidly coupled to the first and second openings, respectively, the first and second backing pad channels extending in a direction normal to the applicator surface;
- a pump to cause the surface coating to flow from the inlet to the first and second openings;
- and
- a motor to rotate the shaft about an axis of rotation while the applicator dispenses the surface coating from the first and second openings, the first opening positioned at a first distance from the axis of rotation, the second opening positioned at a second distance from the axis of rotation different from the first distance.

An effector for use with a robot, the effector comprising:
- a mount to removably couple the effector to the robot;
- an inlet to receive surface coating to be dispensed to a surface of a workpiece;
- a shaft having a fluid channel extending therethrough;
- an applicator having first and second openings, the first and second openings on an applicator surface at a first side of the applicator opposite from a second side of the applicator that is proximate the shaft, the first and second openings in fluid communication with the fluid channel;
- a backing pad to support the applicator, the backing pad including first and second backing pad channels fluidly coupled to the first and second openings, respectively, the first and second backing pad channels extending in a direction normal to the applicator surface;
- a pump to cause the surface coating to flow from the inlet to the first and second openings;
- and
- a motor to rotate the applicator about an axis of rotation while the surface coating is dispensed from the first and second openings and onto the surface, the first opening positioned at a first distance from the axis of rotation, the second opening positioned at a second distance from the axis of rotation different from the first distance.

An apparatus comprising:
- an inlet to receive a surface coating to be applied to a surface of a workpiece;
- a shaft having a first fluid channel extending therethrough, the first fluid channel in fluid communication with the inlet;
- an applicator coupled to an end of the shaft, the applicator having first and second openings in fluid communication with the first fluid channel, the first and second openings on an applicator surface at a first side of the applicator opposite from a second side of the applicator that is proximate the shaft, and wherein a second fluid channel extends from the second opening and angled at 25 to 35 degrees from the first fluid channel, the first and second openings extending in a direction normal to the applicator surface to meet the first and second fluid channels;
- a pump to cause the surface coating to flow from the inlet to the first and second openings;
- and
- a motor to rotate the shaft about an axis of rotation while the applicator dispenses the surface coating from the first and second openings, the first opening positioned at a first distance from the axis of rotation, the second opening positioned at a second distance from the axis of rotation different from the first distance.
