Abstract
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.
Claims14
An industrial robot for food industry wherein the robot has a plurality of joints, a transmission system for moving the joints, and a leakage detection device for detecting a liquid leaking into the robot, wherein 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 at least one indicator strip,
- wherein the leakage detection device is capable of distinguishing between lubricant and water;
- wherein said at least one indicator strip is a pH-strip configured to change color in dependence on the pH value of a liquid in contact with the pH-strip.
