In the initial state, the frame on one side is in a horizontal state. The robotic arm drives the support to move down to grip the workpiece. Then, the drive motor drives the rotating shaft to rotate so that the workpiece is in a vertical state. The cylinder drives the workpiece to move towards the suction cup assembly on the other side for adsorption. The suction cup assembly on the other side rotates to a horizontal state under the action of the drive motor.
