AI Technical Summary
Technical Problem
Existing cleanroom robots suffer from problems such as complex sealing structures, high costs, and poor sealing performance, especially in high-pressure environments where they are prone to dust or grease leakage.
Method used
The ring-shaped seal includes a base and a deformable lip. The lip extends axially and radially inward along the seal. The internal high pressure deforms the lip to enhance the sealing effect, and a stable sealing connection is achieved through the tip abutting.
Benefits of technology
A simple structural design for robot joints has been achieved, which is easy to install and effectively prevents dust or grease leakage under high pressure, thus improving sealing and reliability.

Abstract
The application provides a robot joint and a robot, and relates to the technical field of robots, and the robot comprises a robot joint, the robot joint comprises a moving part and a static part, the moving part can rotate relative to the static part, an annular seal is arranged between the moving part and the static part, the seal comprises a base and at least one deformable lip, the lip extends in the axial direction of the seal and extends radially inward, the end of the lip forms a tip, the tip of the end of the lip abuts one of the moving part and the static part, and the base abuts at least the other one of the moving part and the static part. Since the deformable lip extends in the axial direction of the seal and extends radially inward, when high pressure is generated inside the robot joint, the high pressure will force the lip to deform from the relative inner side of the robot joint to the relative outer side, which makes the lip adhere more tightly to the moving part or the static part, so that the sealing effect of the seal is strengthened by using the internal high pressure.
