Then, the servo motor 520 drives the transmission shaft 550 to rotate through the transmission belt 580, which in turn drives the lead screw 540 to rotate, which in turn drives the nut seat 560 to move on the lead screw 540, thereby driving the push plate 570 to move. The push plate can push the heat sink to be riveted to the riveting position. After riveting, a new heat sink to be riveted is pushed to the riveting position. The riveted heat sink is then pushed forward by the new heat sink to the unloading position. This cycle can be repeated to continuously load and unload materials.
