HRC-compliant KUKA robots in quality assurance

MRK-Systeme GmbH has developed an automation solution with HRC capability (human-robot collaboration) for the BMW Group using KUKA robots for high payloads. It enables the factory in Landshut, Bavaria to carry out quality assurance for crankshaft housing in an ergonomically friendly manner.

KUKA robot ensures better ergonomics

The crankshaft housing is delivered into the workspace by a conveyor. The operator controls the movements of the robot via joystick. The KR QUANTEC moves to the housing along a defined path, grips the component and brings it to the operator. The operator inspects the crankshaft housing using a cold light lamp. During this, the robot securely holds the component weighing roughly 30 kg at the optimum height for the employee. Once the operator has completed the testing process, he moves the robot with the housing back to the conveyor belt and sets the housing down. The interactive testing process is then ended by pressing a button. In doing so, the employee documents whether the part is “OK” or “not OK”.
The HRC-capable KUKA robot (type KR 210 R2900 prime K from the KR QUANTEC series) is operated via joystick.
Both systems have been operating successfully since 2015. The cycle times are adhered to. The work is significantly more pleasant for the employees. Two further test stands for quality assurance are in the planning stage.
