During the rotation, Under the action of the linear module 911, the tightening head 914 moves downward, thereby screwing the nut 104 to the outside of the screw 101. After the nut 104 is tightened, the bracket assembly is completed, and the chain conveyor 41 conveys the assembled bracket to the top of the third release cylinder 45. The two third release cylinders 45 push one end of the clamp 42 to open the clamp 42. The clamp 42 no longer clamps the screw 101. Then the unloading robot 2 can clamp the assembled bracket and place it on the unloading mesh belt line 3 for unloading.
