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...23 Aug. 2019
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. Cylinder blocks and heads are manufactured on four lines at Nissan Dongfeng. At the end of each line, there is a cleaning station, with one cell for the precleaning and one for the final cleaning. The cycle time per station must not exceed 65 seconds. There are TX200 HE robots. They hoists the cylinder block and heads with a gripper from a roller conveyor, swings it across to a bath and lowers it until it is submerged. To ensure that the nooks and crannies are reliably flushed, the six-axis robot follows a meticulously programmed motion profile. Subsequently, the thoroughly cleansed part is passed through a drying unit.
