A multi-axis servo transfer mechanism is used between the presses to transport parts in one go. Although the mechanisms of different manufacturers' presses vary, they can generally be classified into two categories: one is to install a multi-degree-of-freedom transfer robot on the longitudinal axis of the press, and the robot can move longitudinally along the press axis; the other is to install parallel mechanical arms at the front and rear of the columns of two presses, and transport the parts through a terminal gripper in the form of a crossbar.
