New semi-automatic machine for assembly and testing of door modules for truck M.A.N. The machine is equipped with 2 ABB robots and 3 screw spindles. After manual filling of the components by the operator, they are screwed together by means of screw spindles with automatic screw feeding. After completing all parts, the assembly function is tested and all components are checked correctly using the Keyence camera system. It is interesting to apply the OK label directly to the part using a robot.
