[0045] How it works

[0046] Put the wire connected with the pin into the plug slide 17, start the motor 23, and the two motors 23 rotate in the same direction, driving the two rotating shafts 21 to rotate in the same direction. The belt 22 on the rotating shaft 21 starts to rotate, and the first spring 20 pushes out the pressure plate 19, and the pressure plate 19 drives the connecting rod 18 to push out the belt 22, applying a certain pressure on the pin. The rotation of the belt 22 rotates the pin in the plug slide 17 together, and under the pressure of gravity and more pin wires, the rotating pin is pushed downward.

[0047] The pin of the ground wire in the triangular plug cannot move down because the baffle 26 blocks the pin slide 25. When the other two pins in the triangular plug align with the pin slide 25 and start to slide down, the pin pushes the inclined wedge 29 to move outward, the inclined wedge 29 drives the connecting rod 27 to move, and the connecting rod 27 pulls the two baffles 26 apart. At this time, the aligned upper pin slides down. After the pin passes, the two baffles 26 are closed again under the action of the second spring 28 and wait for the next alignment.

[0048] After the pin reaches the bottom, the electromagnetic slider 38 starts to drive the slider 31 to slide towards the plug board 40, and the slider 31 drives the toggle rod 30 to move, and the toggle rod 30 moves with the pin. When the toggle plate 37 passes the first gear 33, it will be pressed against the slider 31. When the slider 31 moves to the end, the plug is inserted between the first clamping plate 42 and the second clamping plate 43 in the plug board 40, and the pin is clamped under the action of the fifth spring 44 and the sixth spring 45. The electromagnetic slider 38 is powered off, and the slider 31 is pushed back under the action of the fourth spring 39. After passing the first gear 33, the toggle plate 37 is reopened. During the retreat of the slider 31, the first gear 33 is toggled to rotate the first gear 33, and the first gear 33 drives the second gear 34 to rotate, and the second gear 34 drives the rack 35 to move, and the rack 35 drives the plug board 40 to move, aligning another plug clamping component 16 with the plug slide 17. After one plug board is fully inserted, it can be pushed into the injection molding machine 12 at the rear for injection molding.

Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
