Vacuum coupling for robot arm
First Claim
1. A vacuum coupling configured to apply vacuum from a vacuum source to a rotatable vacuum tool, the rotatable vacuum tool being attached to a rotatable end of a robotic arm, the vacuum coupling comprising:
- a fixed portion coupled with the vacuum source;
a rotating portion extending through the fixed portion, wherein the rotating portion is rotatable relative to the fixed portion, wherein the rotating portion comprises a first end coupled with the rotating end of the robotic arm and a second end coupled with the rotatable vacuum tool; and
at least one seal between the fixed portion and the rotating portion wherein the at least one seal comprises a fixed vacuum seal and a rotating vacuum seal, wherein one of the fixed vacuum seal and the rotating vacuum seal forms a seal with the fixed portion and the other of the fixed vacuum seal and the rotating vacuum seal forms a seal with the rotating portion.

Abstract
A vacuum coupling applies vacuum from a vacuum source to a rotating tool attached to a rotating end of a robotic arm. The vacuum coupling includes a rotating portion attaching the rotating tool to the rotating end of the robotic arm. The rotating portion communicates vacuum with the rotating tool. A fixed portion is positioned around the rotating portion such that the rotating portion is rotatable relative to the fixed portion. The fixed portion communicates vacuum to the rotating portion. At least one rotating vacuum seal is positioned between the fixed portion and the rotating portion.
