By providing the third spring 712, it can rebound after the isolation frame 711 rotates.

[0038] Working principle: When in use, the operator holds the grip 49 and moves the frame 44 to insert the rolling wheel 45 into the card slot of the second base plate 3, and makes the first clamping tube 46 tightly sleeved in the inner cavity of the first clamping rod 42, and makes the soft pad 43 tightly contact with the first clamping tube 46; the operator connects the motor 52 to the power supply and turns on the switch of the motor 52, so that the rotating rod 53 drives the connecting disk 57 and the wavy rotating disk 56 to rotate. When the wavy rotating disk 56 rotates, it will contact the roller 515, and then the moving column 510 moves upward in the inner cavity of the limiting tube 59, so that the impact block 511 impacts the lower surface of the fixed disk 516. When the wavy rotating disk 56 continues to rotate, the impact block 511 continuously impacts the fixed disk 516, so that the end with a lower center of gravity of the part can be located below, achieving the effect of arranging the parts. When the rotating rod 53 rotates, it drives the track tube 5192 to rotate, and then the moving rod 5193 and the pushing plate 5196 push the parts in the inner cavity of the spiral frame 517, and push the parts to one side of the spiral frame 517 located on the outer surface of the housing 51; the operator controls the PPU manipulator 8 to clamp the parts located at the end of the spiral frame 517 and place the parts on the upper surface of the placement plate 76. Then, the storage battery 74 generates current, so that the strong magnet 77 generates suction and positions the parts. Then, controlling the welding mechanism 6 to work can weld the parts. Then, control the storage battery 74 to stop working, and control the PPU manipulator 8 to extrude the parts. Under the extrusion, the barrier frame 711 rotates, and the parts fall into the inner cavity of the chute 67 and finally fall into the inner cavity of the aggregate box 9.
