Robot for preparing food or drink

A robot joint including a first part and a second part arranged to have a relative movement in between, and a joint gap spacing the first part and the second part from each other, wherein the robot joint includes an inflatable seal accommodated in the joint gap to provide a fluid-tight sealing of the joint. The disclosure also relates to a robot including the robot joint, a system including the robot and a method for sealing a joint gap of a robot joint.

Robot joint and method for sealing a joint gap of a robot joint

A sealing device () for providing a fluid-tight sealing of a joint comprising a first part () and a second part () with a relative movement in between. The sealing device () comprises: an outer sealing part () designed to contact the first part and the second part, an inner sealing part () designed to contact the first part and the second part, and a spacing structure () connecting the outer sealing part () and the inner sealing part (). The outer sealing part () and the inner sealing part () define an intermediate space () between the outer sealing part () and the inner sealing part (). The outer sealing part () and the inner sealing part () are being configured to seal off the intermediate space () from both an exterior and an interior of the joint, and the intermediate space () is configured to be influid contact with both the first part () and the second part ().

Sealing device

An industrial robot for food industry having a leakage detection device for detecting a liquid leaking into the robot, and the leakage detection device includes at least one indicator strip arranged inside the robot and configured to change color in contact with a liquid, a sensor module configured to detect changes in color of the at least one indicator strip, and a detector unit configured to determine presence of liquid inside the robot based on the detected color changes of the indicator strip, and the leakage detection device in is capable of distinguishing between lubricant and water.
