[0092] Step S43: The flipping component 321 flips the workpiece, and the double Y-axis moving carrier track 22 drives the tooling base plate 331 to be transported along the first preset direction to the output port. The pneumatic clamp 334 releases the workpiece, and the workpiece is picked up and stacked and output by the output robotic arm.
