A precision hardware processing company has applied the Delta SCARA robot for the feeding and blanking processes on its stamping press. In this project, the precision stamping press adopts Delta SCARA DRS40L3SS1 and a machine vision system. When the blank in the feeding and blanking mechanism of the press exits the vibrator bowl and is transfered by the conveyor belt to the retrieval range of Delta SCARA, the machine vision system detects the blank, and sends the coordinates and angle of the blank to SCARA. After SCARA receives the information, the suction cup at the end of the mechanical arm is placed on top of the blank, and lowered to retrieve the blank, which is then moved to the press mold of the rotating temporary storage platform at the center of the press. After the press stamp and form the blank in the rotating temporary storage platform, the platform will rotate 180 degrees to deliver the finished piece while feeding the new blank into the press processing area. When SCARA receives the material exit signal from the press, the finished piece will be retrieved and placed on a storage tray. The cycle will continue by repeating the movements above. Illustration of the processing is shown in Photo1.

This process has a ±0.2 mm positioning accuracy on the Delta SCARA end, and a ≤ 2.5 seconds operation cycle for the feeding and blanking processes. It has high position precision and loading, which offers long-term, stable, error-free operations. It can adopt multiple installation methods, and is a highly expandable system. The parameter configuration is simple and easy to maintain. The product also offers high-speed bit motion, spatial linear interpolation motions, and spatial circular interpolation motions.
