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 inward, forming a transverse restraining structure for inserting the card holder. 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 contact 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 both states, the second pressing plate 452 is designed with two shapes of first extrusion grooves 4521 and second extrusion grooves 4522 on both sides. 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 sets 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 ferrule 9a into a stable shape.

[0097] In this embodiment, the first loading component 48 includes a first storage track 481, and a plurality of groups of ferrules 9a are stored in the first storage track 481. A push plate 482 is slidably provided at one end of the first storage track 481. 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 ferrule 9a in the first storage track 481 to the sealing plate 46; an L-shaped baffle 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 47 is retracted, the baffle 47 is placed above the notch 41, and when the baffle 47 rotates downward, the baffle 47 pushes the ferrule 9a to the surface of the sealing plate 46 and stops the inserted wire core.

[0098] In the above scheme:

[0099] During loading, the blocking rod 47 is stored on the back of the vertical box body 43 and located above the notch 41. 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. Subsequently, 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] Subsequently, the first material storage track 481 moves inward and is retracted. Subsequently, the third motor 471 drives the stop rod 47 to rotate downward. The L-shaped stop rod 47 contacts the ferrule 9a, causing the ferrule 9a to move inward a second time until the ferrule 9a contacts the baffle 454, ensuring that the ferrule 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.

[0102] In this embodiment, the ferrule 9a is a round tube with a notch, and the lower holder 8 includes a lower base plate 81 and a clamping spring 82. The interior of the lower base plate 81 is symmetrically provided with a positioning groove 811, and the middle part of the surface of the lower base plate 81 is symmetrically provided with a clamping spring 82. The ferrule 9a is fitted and embedded in the two sets of clamping springs 82.

[0103] In the above solution, when the ferrule 9a is inserted, the ferrule 9a enters between the two sets of clamping springs 82, so that the clamping springs 82 can clamp the end of the positioning wire core.

[0104] In this embodiment, the upper contact piece 9 includes an upper sleeve 91, an upper substrate 911, a card plate 92, and a conductive connecting piece 93. The side section of the upper sleeve 91 is an inverted U shape. Upper substrates 911 are provided on both sides of the upper sleeve 91. The bottom surface of the upper substrate 911 is provided with a card plate 92. The card plate 92 is fitted into the positioning groove 811. The upper sleeve 91 is mounted on the upper part of the clamping spring piece 82. A resistance strip 912 is provided in the middle of the inner wall of the upper sleeve 91. The resistance strip 912 extends between the two groups of clamping spring pieces 82 and presses down the card sleeve 9a; a conductive connecting piece 93 is provided on the side of the upper sleeve 91.

[0105] In the above scheme: when the upper contact piece 9 is connected, the upper sleeve 91 descends, the clamping plate 92 is clamped 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 round 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 inner diameter of the upper groove body is larger than the inner diameter of the lower groove body. A middle block 52 is provided in the middle of the interior of the lower groove body. The two sides of the middle block 52 are avoidance grooves 53. The lower base plate 81 is fitted and embedded in the upper groove body. The positioning groove 811 is located above a group of avoidance grooves 53. The middle block 52 is located in the middle of the bottom of the lower base plate 81.

[0107] The second loading component 6 includes a second storage track 61, and the interior of the second storage track 61 stores lower card seats 8 distributed in a linear array. The top outlet end of the second storage track 61 is installed with a first loading guide rail 62, and the bottom surface of the first loading guide rail 62 is vertically slidably installed with a fourth driving rod 63, and the bottom end of the fourth driving rod is installed with a first material picking claw 64.

[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.

[0109] In this embodiment, the packaging component 7 includes a third material storage track 71, which stores a plurality of material storage slots for placing contact pieces 9 of different sizes. The top outlet end of the third material storage track 71 is installed with a second loading guide rail 72, and the bottom surface of the second loading guide rail 72 is vertically slidably installed with a moving block 73. The bottom surface of the moving block 73 is rotatably connected to the hanging plate 75 and a fourth motor 74 is installed at the rotating connection. A fifth drive rod 76 is vertically provided at one end of the bottom surface of the hanging plate 75 and a sixth drive rod 77 is vertically provided at the other end. The bottom end of the fifth drive rod 76 is connected to the second material picking clamp 761, and the bottom end of the sixth drive rod 77 is provided with a pressure cover 771.

[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 stuck in the positioning groove 811.
