Drum forming. According to the inquiry of industrial network, this shaping method makes the conveying speed of silicon wafer slow, and the aging and wear of the roller of the shaping mechanism easily leads to chip sticking and chip tilting. The automatic silicon wafer inserter is mainly composed of four parts: mechanical system, control system, sensor system and positioning system. The mechanical system includes linear motor, pneumatic system, lead screw, guide rail and other parts, which are responsible for the positioning and movement of silicon wafer.
