Cushion Pin Control System with Using Image Processing

Abstract

Gas cylinders and cushion pins can be used in presses, which are the most used machines in metal forming.In the placement of the cushion pins on the press table, the operators find the right holes with the help of a map and place the cushion pins into the holes.When the cushion pins are placed in the wrong holes, it can cause permanent damage to the press, mold or metal sheets.In order to prevent these errors, although there are systems to guide the operators visually, there are no systems to control each hole according to each map. In the study, a virtual orientation was placed on the real image according to the map information using AR technology. Finally, each hole was controlled using image processing and deep learning methods using motion sensors on the camera, lidar and tablet.As a result, an inexpensive and effective result was produced using only a tablet with a camera and lidar.
