A U-shaped frame 4511 is provided at the output end of the third driving rod 451. The second pressing plate 452 is rotatably installed at the inner end of the U-shaped frame 4511, and a second motor 453 is installed at the rotating connection. A first extrusion groove 4521 is provided on one side of the second pressing plate 452, and a second extrusion groove 4522 is provided on the other side. A baffle 454 is vertically provided on the inner wall of the first extrusion groove 4521. The shape of the inner wall of the first extrusion groove 4521 is adapted to the initial shape of the ferrule 9a, and the shape of the second extrusion groove 4522 is adapted to the shape of the ferrule 9a after extrusion.

[0092] When the first loading component 48 is loading, the first extrusion grooves 4521 of the two sets of second pressing plates 452 face inwards, and the first extrusion grooves 4521 of the two sets of second pressing plates 452 form a transverse restraint structure for inserting the card holder, and the first pressing plate 442 restrains the introduced card sleeve 9a from above, and the baffle 454 longitudinally resists the introduced card sleeve 9a;

[0093] In the second state, the second extrusion grooves 4522 of the two groups of second pressing plates 452 face inward, the second extrusion grooves 4522 of the two groups of second pressing plates 452 resist against the ferrule 9a to close, and the second pressing plates 452 constrain the closed ferrule 9a from above.

[0094] In the above scheme:

[0095] 1. Since the initial shape and the closed shape of the ferrule 9a are different, in order to ensure stable processing in the two states, the two sides of the second pressing plate 452 are designed to have two shapes of first extrusion grooves 4521 and second extrusion grooves 4522. When the ferrule 9a is loaded, the third driving rod 451 adjusts the second pressing plate 452 to a position with the first extrusion grooves 4521 facing inward. In this way, the two groups of first extrusion grooves 4521 can constrain and position the inserted ferrule 9a from both sides;

[0096] 2. The second pressing plate 452 is designed to be a rotatable structure. The second motor 453 can drive the second pressing plate 452 to rotate in the U-shaped frame 4511 so that the second extrusion groove 4522 faces inward. In this way, when the third driving rod 451 drives the U-shaped frame 4511 to move inward, the second extrusion groove 4522 can extrude the sleeve 9a to form stably.

[0097] In this embodiment, the first loading component 48 includes a first storage track 481, in which a plurality of groups of ferrules 9a are stored, and a push plate 482 is slidably provided at one end of the first storage track 481, and the first storage track 481 is longitudinally slidably installed on the inner wall of the support box 42, and the push plate 482 is used to push the ferrules 9a in the first storage track 481 to the blocking plate 46; an L-shaped baffle rod 47 is rotatably installed on the back of the vertical box body 43 and a third motor 471 is installed at the rotating connection; when the baffle rod 47 is stored, the baffle rod 47 is placed above the notch 41, and when the baffle rod 47 is rotated downward, the baffle rod 47 pushes the ferrule 9a to the surface of the blocking plate 46 and stops the inserted wire core.

[0098] In the above scheme:

[0099] When loading, the blocking rod 47 is stored on the back of the vertical box body 43 and located above the notch 41, and the first material storage track 481 slides longitudinally so that the end of the first material storage track 481 is aligned with the notch 41. Then, the push plate 482 moves to push the ferrule 9a forward, so that a group of ferrules 9a enter the blocking plate 46 from the back notch 41. During the insertion process, the first extrusion groove 4521 constrains the ferrule 9a from both sides, and the first pressing plate 442 constrains the ferrule 9a from the top.

[0100] Then, the first material storage track 481 moves inward and is retracted, and then the third motor 471 drives the stopper 47 to rotate downward, and the L-shaped stopper 47 contacts the card sleeve 9a, so that the card sleeve 9a moves inward for a second time until the card sleeve 9a contacts the baffle 454, ensuring that the card sleeve 9a is accurately positioned;

[0101] After the ferrule 9a is in place, the two sets of first pressing plates 442 are rotated and adjusted, and the blocking rod 47 keeps contacting the ferrule 9a from the inner end.

The resistance strip 912 extends between the two groups of clamping spring pieces 82 and presses down the clamping sleeve 9a. The side of the upper sleeve 91 is provided with a conductive connecting piece 93.

[0105] In the above scheme: when the upper contact piece 9 is connected, the upper sleeve 91 descends, the clamping plate 92 is inserted into the positioning groove 811, the upper sleeve 91 is surrounded above the clamping spring piece 82, and the resistance bar 912 presses down the clamping sleeve 9a, so that the upper contact piece 9 is stably assembled; when separating, the clamping plate 92 is pulled to facilitate lifting and separating from the upper sleeve 91; a circular hole is opened in the conductive connecting piece 93 for easy positioning.

[0106] In this embodiment, a receiving groove 51 is provided at each placement station on the surface of the movable carrier 5. The inner end of the receiving groove 51 is open and the outer end is closed. The receiving groove 51 includes an upper groove body and a lower groove body.

The positioning groove 811 is located above a group of avoidance grooves 53. The middle block body 52 is located in the middle of the bottom of the lower base plate 81.

[0108] In the above scheme: the first material picking clamp 64 can clamp the lower clamp 8 in the second material storage track 61, and then transfer it to the top of the accommodating groove 51, and the fourth driving rod 63 drives the first material picking clamp 64 to descend, so that the lower clamp 8 is embedded in the upper groove body, and the positioning groove 811 is relatively located above the avoidance groove 53 to facilitate the insertion of the clamping plate 92.

[0110] In the above scheme: when packaging the upper contact piece 9, the moving block 73 moves along the second loading guide rail 72, the second material picking clamp 761 clamps the upper contact piece 9 and transfers it to the lower clamping seat 8, and then the fourth motor 74 drives the hanging plate 75 to rotate, so that the pressure cover 771 is located on the upper contact piece 9, and then the sixth driving rod 77 drives the pressure cover 771 to descend, and the pressure cover 771 presses down the upper sleeve, so that the clamping plate 92 is clamped into the positioning groove 811.
