Realize the transfer of the white body between the roller bed and the swing bar. The positioning and parking of the skid body can be realized by the trolley device, the car stopper and other devices to ensure the accuracy of the handover. The positioning device is divided into two types: pneumatic and electric. 　　Exit rolling bed: 　　After electrophoresis, the body is separated from the swing rod and transferred to the rolling bed. The overall frame is equipped with a spring support and a buffer device, which can effectively eliminate the additional force generated when the pendulum rod is handed over, ensuring smooth handover and stable equipment.
