The customer invested in an automated machining station for motor rotors, where a 3D vision-guided robot completes the CNC up- and down-stacking of the workpieces. The rotor itself has very high reflective properties, and due to its special shape it can only be stacked in pyramid-like stacks, and the gripping and placing had to be done in the order of up and down, and a sensible gripping logic had to be set up to prevent the stack from collapsing. The 3D vision system guides the robot to depalletise and load the workpieces by accurately positioning the stacks, and at the same time identifies the remaining stacks in the downstream work station, so as to guide the robot to accurately place the finished processed rotor products and achieve reasonable palletising. finished products and achieve reasonable palletising.
