Embodiment Construction

[0032] In the following, a fluid-tight robotic joint having a joint, as well as a robot comprising at least one such robotic joint, a system comprising the robot and a method for sealing such a robotic joint will be described.

[0033]The robotic joints described herein are provided with expandable seals. An expandable seal is provided in a joint space separating a first part and a second part of the robot joint, the first part and the second part having relative movement therebetween. With such robotic joints, it is possible to meet the conflicting requirements for a single joint seal, thus both sealing the joint and allowing the various parts of the joint to move relative to each other, since the expandable seal can work in different modes. In the first mode, the inflatable seal provides operational protection. For example, when a robot is operating in a meat processing plant, the inflatable seal should protect against external contamination, such as splashes of incoming bl...

Abstract

A robot joint (20) comprises a first part (22) and a second part (24) arranged to have a relative movement in between, and a joint gap (26) spacing the first part (22) and the second part (24) from each other, wherein the robot joint (20) comprises an inflatable seal (10) accommodated in the joint gap (26) to provide a fluid-tight sealing of the joint (20). The disclosure also relates to a robot (100) comprising the robot joint (20), a system comprising the robot (100) and a method for sealing a joint gap of a robot joint (20).

Description

technical field [0001] The present disclosure relates to fluid sealing of robotic joints, and in particular sealing of robotic joints comprising a first part and a second part with relative movement therebetween. The present disclosure also relates to a robot comprising at least one such joint, a system comprising the robot and a method for sealing a joint of the robot. Background technique [0002] Equipment used in food processing in the protein industry (i.e. meat, poultry, fish, seafood and dairy products) has strict hygiene requirements and must be washed daily using high-pressure hot water and chemical reagents. Robots used for food processing in washdown applications should have a full stainless steel frame that is hygienically designed for easy cleaning. Robots need to have a high waterproof rating - Ingress Protection 69K (IP69K). The IP69K rating defines the protection that needs to be provided against the ingress of dust and high-temperature, high-pressure water...
