When Stäubli first launched the six-axis HE, this paved the way for the use of robots in industrial parts cleaning.

The parts to be cleaned reach the stations on four lines via a roller conveyor from which they are hoisted up by the robot.


Six-axis machines for inline parts cleaning

100 percent humidity and a pH of 9: in such conditions, the deployment of robots poses real challenges. These are the very parameters under which Stäubli robots are delivering reliable service on the parts cleaning line at the Nissan Dongfeng engine plant in China. Component cleanliness plays an extremely important role in modern engines. Even the most minimal contamination can lead to damage with severe consequences, which is why parts cleaning is considered so crucial. In the automotive industry, clearly defined residual contamination criteria apply, which can only be permanently adhered to when reliable processes are in place.

On this basis, an efficient and highly automated parts cleaning line was installed at the plant in Huadu. When it first went into operation, though, the six-axis robots installed were not supplied by Stäubli but rather by another manufacturer. However, these were not able to cope with the tough conditions. Frequent breakdowns and high maintenance costs eventually pe
