[0037] See also Figures 2 to 4 , Figure 2 2 is a schematic structural diagram of the wire clamping fixture 200 provided by the present invention in a flat state. Figure 3 2 is a schematic structural diagram of the wire clamping fixture 200 provided by the present invention in a flipped state. Figure 4 2 is a schematic diagram of the exploded structure of the wire clamping fixture 200 provided by the present invention.

[0038] The wire clamping fixture 200 includes a fixing base 210 , a connecting block 220 , a clamping jaw assembly 230 and a positioning member 240 .

[0039] The connecting block 220 is rotatably connected to the fixed base 210 around a first rotating axis, which is the rotation axis of the two. The connecting block 220 is provided with multiple positioning holes around the first rotating axis, and the centers of the multiple positioning holes are on the same circular ring; the clamping jaw assembly 230 is rotatably connected to the connecting block 220 around a second rotating axis, which is the rotation axis of the two. The first rotating axis and the second rotating axis are perpendicular to each other, wherein the fixed base 210 and the connecting block 220 are used to carry multi-core wires, and the clamping jaw assembly 230 is used to clamp the multi-core wires. The purpose of rotating the connecting block 220 relative to the fixed base 210 is to bend the multi-core wires, and the purpose of rotating the clamping jaw assembly 230 relative to the connecting block 220 is to place the multi-core wires into the connecting block 220 to clamp the multi-core wires. The rotation of the connecting block 220 depends on the push of the first driving assembly, and the rotation of the clamping jaw assembly 230 depends on the push of the second driving member.

[0040] Positioning member 240 is connected to fixing base 210 and elastically inserted into at least one of the multiple positioning holes. The multiple positioning holes rotate with connecting block 220. After rotating to a certain angle, positioning member 240 can be inserted into one of the multiple positioning holes, or two of the multiple positioning holes, etc. After positioning member 240 is elastically inserted into the positioning hole, connecting block 220 and fixing base 210 remain in a relatively fixed state. That is, the positioning member 240 cooperates with the positioning hole to further improve the rotation angle of connecting block 220. The end of positioning member 240 is a spring-connected ball. When pressure is applied, the ball retracts into positioning member 240. When there is no pressure, the ball is inserted into the positioning hole under the action of the spring.

[0041] The fixing base 210 is provided with a retaining groove 212, which is U-shaped and includes a first wall 213, a second wall 214 and a third wall 215 connected in sequence. The end of the connecting block 220 is inserted into the retaining groove 212. The first rotation axis passes through the first wall 213, the connecting block 220 and the third wall 215 in sequence. The second wall 214 forms a preset angle with the horizontal direction. The second wall 214 is used to stop the connecting block 220 so that the connecting block 220 rotates at a preset angle. Figure 3 As shown, the preset angle is 90 degrees. After the connecting block 220 rotates 90 degrees from the horizontal state, it will abut against the second wall 214, thereby preventing the connecting block 220 from further rotating. The preset angle can also be 60 degrees, 45 degrees, 30 degrees, etc.

[0042] The fixing base 210 is provided with a first limiting groove 211, and the connecting block 220 is provided with a second limiting groove 221. The first limiting groove 211 and the second limiting groove 221 are used to jointly limit the multi-core wire. The slotting directions of the first limiting groove 211 and the second limiting groove 221 are coaxial, ensuring that the multi-core wire can be straightened after being placed in the first limiting groove 211 and the second limiting groove 221. The width of the first limiting groove 211 and the second limiting groove 221 can be consistent with the diameter of the multi-core wire to play a limiting role.

[0043] The clamping jaw assembly 230 includes a first clamping jaw 231 and a second clamping jaw 232. The first clamping jaw 231 and the second clamping jaw 232 are spaced apart and are each rotatably connected to the connecting block 220 about a second rotation axis. The first clamping jaw 231 is used to clamp the outer sheath of the multi-core wire, thereby securing the multi-core wire and preventing it from moving. The second clamping jaw 232 is used to clamp the core wire of the multi-core wire, thereby securing the core wire of the multi-core wire. The first clamping jaw 231 and the second clamping jaw 232 cooperate with each other to secure the end of the multi-core wire after the sheath is stripped.

[0044] The wire clamping fixture 200 also includes a first return spring 250 and a second return spring 260. The first return spring 250 is passed through the first rotating shaft, and the first return spring 250 respectively abuts the fixed seat 210 and the connecting block 220. When the connecting block 220 rotates relative to the fixed seat 210, the connecting block 220 will compress the first return spring 250. After the external force disappears, the elastic force of the first return spring 250 will restore the connecting block 220 to its original state. The second return spring 260 is passed through the second rotating shaft, and the second return spring 260 respectively abuts the connecting block 220 and the clamping jaw assembly 230. When the clamping jaw assembly 230 rotates relative to the connecting block 220, the clamping jaw assembly 230 will compress the second return spring 260. After the external force disappears, the elastic force of the second return spring 260 will restore the clamping jaw assembly 230 to its original state.

[0045] In one embodiment, the wire clamping fixture 200 also includes a plurality of magnets 270, and the plurality of magnets 270 are respectively connected to the clamping jaw assembly 230 and the connecting block 220, that is, a magnet 270 is installed on the clamping jaw assembly 230, and a magnet 270 is also installed on the connecting block 220. The magnets 270 on the clamping jaw assembly 230 and the magnets 270 on the connecting block 220 are magnetically attracted to each other, thereby enhancing the stability of the connection between the clamping jaw assembly 230 and the connecting block 220, ensuring that the multi-core wire is clamped without loosening.

[0046] In another embodiment, the wire clamping fixture 200 further includes a magnet 270, which is disposed on the clamping jaw assembly 230. The magnet 270 is not disposed on the connecting block 220. The magnet 270 directly attracts the connecting block 220 to enhance the connection strength between the connecting block 220 and the clamping jaw assembly 230. Of course, the magnet 270 can also be disposed on the connecting block 220, and the magnet 270 attracts the clamping jaw assembly 230 to enhance the connection strength between the connecting block 220 and the clamping jaw assembly 230.

[0047] The connecting block 220 is provided with a plurality of parallel fixing slots 281 for assembling the multiple core wires of a multi-core cable. The width of each fixing slot 281 is equivalent to the diameter of the core wire. The multiple core wires are distributed in the fixing slots 281 and are spaced apart from each other to prevent overlap.

[0048] Furthermore, the wire clamping fixture 200 also includes a module 280, which is detachably connected to the connecting block 220 and has a plurality of parallel fixing slots 281. In this embodiment, the module 280 is separated from the connecting block 220, and the fixing slots 281 in the above embodiment are provided on the module 280. This has the advantage of facilitating the replacement of the fixing slots 281. Because the fixing slots 281 will constantly rub against the multi-core wires during cyclic use, this will cause wear on the fixing slots 281, increasing the width of the fixing slots 281 and making it impossible to properly secure the wires. In addition, different multi-core wires have different numbers of core wires, which may be 3, 4, 5, 6, etc. Different modules 280 can be used to limit and secure different multi-core wires. The detachable connection between the module 280 and the connecting block 220 can be screw connection, clip connection, etc.

[0049] See also Figure 5 and Figure 6 , Figure 5 1 is a structural diagram of an embodiment of a rough shaping module 300 provided by the present invention. Figure 6 yes Figure 5 Schematic diagram of the enlarged area A in FIG.

[0050] The coarse shaping module 300 includes a main seat, a transverse movement component 320, a vertical movement component 340, a first shaping component 360 and a second shaping component 380. The transverse movement component 320 is connected to the main seat, the vertical movement component 340 is connected to the transverse movement component 320, the first shaping component 360 and the second shaping component 380 are respectively connected to the vertical movement component 340, the transverse movement component 320 is used to push the vertical movement component 340 to move in the transverse direction, that is, to push the vertical movement component 340 toward or away from the multi-core wire, and the vertical movement component 340 is used to push the first shaping component 360 and the second shaping component 380 to move toward each other to jointly clamp and shape the multi-core wire.

[0051] In order to enable those skilled in the art to have a further understanding of the technical solution of the present invention, the following will explain it with a specific implementation method. 1. The transverse moving component 320 pushes the vertical moving component 340 to move toward the multi-core wire, and the end of the multi-core wire is inserted between the first shaping component 360 and the second shaping component 380; 2. The vertical moving component 340 pushes the first shaping component 360 and the second shaping component 380 to move toward each other to jointly clamp and shape the multi-core wire, and separate the multiple strands of single-core wire at the end of the multi-core wire to form a certain distance interval; 3. The transverse moving component 320 pushes the vertical moving component 340 to move in the direction away from the multi-core wire, and then drives the first shaping component 360 and the second shaping component 380 to move in the direction away from the multi-core wire, so that the end of the multi-core wire at a certain distance will be shaped, such as Figure 5 , the multi-core wire changes from state 1 to state 2.

[0052] Specifically, the first shaping assembly 360 includes a first shaping member 361, which is connected to the vertical displacement assembly 340. The first shaping member 361 has a plurality of first shaping grooves 362 and a plurality of first shaping protrusions 364. The plurality of first shaping grooves 362 and the plurality of first shaping protrusions 364 are spaced in sequence, and each first shaping groove 362 is used to accommodate a single strand of core wire. The second shaping assembly 380 includes a second shaping member 381, which is connected to the vertical displacement assembly 340. The second shaping member 381 has a plurality of second shaping grooves 382 and a plurality of second shaping protrusions 384. The plurality of second shaping grooves 382 and the plurality of second shaping protrusions 384 are spaced in sequence, and each second shaping groove 382 is used to accommodate a single strand of core wire. When the first shaping member 361 and the second shaping member 381 move toward each other, the single strand of core wire is accommodated in the first shaping groove 362 and the second shaping groove 382, ​​respectively. The first shaping protrusion 364 is inserted into the second shaping groove 382, ​​and the second shaping protrusion 384 is inserted into the first shaping groove 362, thereby shaping the multi-core wire. In this embodiment, the multi-core wire located in the first shaping groove 362 and the multi-core wire located in the second shaping groove 382 extend in different directions. The first shaping groove 362 and the first shaping protrusion 364 are spaced apart, and the second shaping groove 382 and the second shaping protrusion 384 are spaced apart. This increases the spacing between the multi-core wires in the first shaping groove 362, and of course, also increases the spacing between the multi-core wires in the second shaping groove 382.

[0053] See also Figures 7 to 9 , Figure 7 3D schematic diagram of the rough shaping module 300 according to another embodiment of the present invention. Figure 8 is a cross-sectional schematic diagram of the rough shaping module 300 provided by the present invention, Figure 9 yes Figure 8 Schematic diagram of the enlarged area B.

[0054] The first shaping assembly 360 further includes a first left stopper 363 and a first right stopper 365. The first left stopper 363 and the first right stopper 365 are respectively connected to opposite sides of the first shaping member 361, sandwiching the first shaping member 361 therebetween. The first left stopper 363 defines a first left stopper slot, and the first right stopper 365 defines a first right stopper slot. The second shaping assembly 380 further includes a second left stopper 383 and a second right stopper 385. The second left stopper 383 and the second right stopper 385 are respectively connected to opposite sides of the second shaping member 381, sandwiching the second shaping member 381 therebetween. The second left stopper 383 defines a second left stopper slot, and the second right stopper 385 defines a second right stopper slot.

[0055] The first left limiting groove, the second left limiting groove, the first right limiting groove, and the second right limiting groove are respectively used to limit the multi-core wires. The horizontal projections of the first left limiting member 363, the second left limiting member 383, the first right limiting member 365, and the second right limiting member 385 alternate in sequence. When the first shaping assembly 360 and the second shaping assembly 380 move toward each other, the first left limiting member 363 and the second left limiting member 383 intersect and move relative to each other, and the first right limiting member 365 and the second right limiting member 385 intersect and move relative to each other. The first left limiting groove, the second left limiting groove, the first right limiting groove, and the second right limiting groove jointly limit the multi-core wires, ensuring that each core wire of the multi-core wire moves along its own fixed trajectory.

[0056] Furthermore, the first left stopper 363 and the first right stopper 365 both protrude relative to the end of the first shaping member 361, and the first left stopper 363, the first shaping member 361, and the first right stopper 365 collectively form a concave shape. The second left stopper 383 and the second right stopper 385 both protrude relative to the end of the second shaping member 381, and the second left stopper 383, the second shaping member 381, and the second right stopper 385 collectively form a concave shape. In this embodiment, the first left stopper 363, the first right stopper 365, the second left stopper 383, and the second right stopper 385 preferentially abut against the multi-core wire over the first shaping member 361 and the second shaping member 381, thereby limiting the multi-core wire and ensuring that the multi-core wire smoothly enters the first shaping groove 362 and the second shaping groove 382 during the extrusion process.

[0057] The first shaping assembly 360 further includes a fixing member 367 and an elastic member 369. The first shaping member 361 is slidably connected to the vertical movement assembly 340, the fixing member 367 is connected to the vertical movement assembly 340, and one end of the elastic member 369 is connected to the fixing member 367, and the other end is connected to the first shaping member 361. When the vertical movement assembly 340 drives the first shaping member 361 toward the multi-core wire and abuts the multi-core wire, the sliding movement of the first shaping member 361 relative to the vertical movement assembly 340 compresses the elastic member 369, causing the first shaping member 361 to move downward more slowly relative to the vertical movement assembly 340, thereby acting as an elastic buffer to prevent damage to the multi-core wire.

[0058] Furthermore, the second shaping member 381 is detachably connected to the vertical displacement assembly 340. The second shaping member 381 cooperates with the first shaping assembly 360 to shape the multi-core wire. The shaping is achieved by squeezing, so there is a reverse force on the second shaping member 381. Long-term use causes a certain amount of wear to the second shaping member 381. When the second shaping member 381 and the vertical displacement assembly 340 are detachable, the second shaping member 381 can be quickly removed and replaced.

[0059] The second shaping assembly 380 also includes a stopper 387, which is connected to the vertical displacement assembly 340 and abuts the end of the second shaping member 381 facing away from the first shaping member 361. When the first shaping member 361 and the second shaping member 381 shape the multi-core wire, the second shaping member 381 is subjected to a reaction force, that is, a force in a direction away from the first shaping member 361. This can cause the second shaping member 381 to deform away from the first shaping member 361. Over time, this can cause irreversible damage to the second shaping member 381. Therefore, the stopper 387 is provided at the end of the second shaping member 381 facing away from the first shaping member 361 to provide auxiliary support for the second shaping member 381 and prevent deformation.

[0060] The transverse movement assembly 320 includes a transverse guide rail 321, a transverse slider 323, and a transverse cylinder 325. The transverse guide rail 321 is disposed on the main body seat. The transverse slider 323 is slidably connected to the transverse guide rail 321 and is connected to the transverse cylinder 325. The vertical movement assembly 340 is connected to the transverse slider 323. The transverse cylinder 325 is used to push the transverse slider 323 to move in the transverse direction. When the transverse cylinder 325 pushes the vertical movement assembly 340 to move, the vertical movement assembly 340 drives the first shaping assembly 360 and the second shaping assembly 380 to move laterally together. The transverse cylinder 325 can be a distance-limiting cylinder. A limit block is provided at the end of the transverse cylinder 325. The limit block limits the movement of the transverse cylinder 325 to a distance range, thereby ensuring that the first shaping assembly 360 and the second shaping assembly 380 can move exactly to the end of the multi-core wire without further movement.

[0061] The vertical movement assembly 340 includes a vertical guide rail 341, multiple vertical sliders 343, and multiple vertical cylinders 345. The vertical guide rail 341 is disposed on the main body seat. The multiple vertical sliders 343 are slidably connected to the vertical guide rail 341 and are respectively connected to the multiple vertical cylinders 345. The first shaping assembly 360 is connected to some of the vertical sliders 343, and the second shaping assembly 380 is connected to another part of the vertical sliders 343. Some of the vertical cylinders 345 are used to push the first shaping assembly 360 to move, and the other part of the vertical cylinders 345 are used to push the second shaping assembly 380 to move. The drawings of the present invention show two vertical sliders 343 and two vertical cylinders 345. One vertical slider 343 is connected to one vertical cylinder 345. The first shaping assembly 360 is connected to one vertical slider 343, and the second shaping assembly 380 is connected to the other vertical slider 343. Of course, the number of vertical sliders 343 can also be four, and the number of vertical cylinders 345 can be two, with two vertical sliders 343 connected to one vertical cylinder 345. Other combinations are not detailed here. The vertical cylinder 345 can be a distance-limiting cylinder, with a stopper provided at the end of the vertical cylinder 345. The stopper limits the movement of the vertical cylinder 345 within a range of distances, thereby ensuring that the first shaping assembly 360 and the second shaping assembly 380 can properly clamp the multi-core wire without excessively squeezing the multi-core wire.

[0063] The correction module 400 includes a base seat 420, a displacement component 440, a rotation component 460 and a clamping component 480. The displacement component 440 is connected to the base seat 420, the rotation component 460 is connected to the displacement component 440, and the clamping component 480 is connected to the rotation component 460. The displacement component 440 is used to push the rotation component 460 to move toward the multi-core wire and insert it into the multi-core wire. The clamping component 480 is used to press the multi-core wire onto the rotation component 460. The rotation component 460 is used to drive the multi-core wire to rotate a preset angle. The preset angle is determined by the angular deviation of the multi-core wire relative to the joint weld foot before correction. The preset angle can be 1 degree, 2 degrees, 3 degrees, etc.

[0064] To help those skilled in the art gain a deeper understanding of the technical solutions of the present invention, the following will be explained using a specific implementation method. 1. The displacement assembly 440 pushes the rotation assembly 460 toward the multi-core wire and inserts it into the end of the multi-core wire. 2. The clamping assembly 480 presses the multi-core wire onto the rotation assembly 460. 3. The rotation assembly 460 drives the clamping assembly 480 and the multi-core wire to rotate together at a preset angle so that the multi-core wire and the joint weld leg have the same shape. 4. The displacement assembly 440 pushes the rotation assembly 460 away from the multi-core wire, and the clamping assembly 480 and the rotation assembly 460 move together to straighten and shape the multi-core wire.

[0065] The displacement assembly 440 includes a displacement cylinder 441, a displacement rail 443, and a displacement slider 445. The displacement cylinder 441 and the displacement rail 443 are connected to the base 420. The displacement rail 443 extends toward the multi-core wire. The displacement slider 445 is connected to the output end of the displacement cylinder 441 and is slidably connected to the displacement rail 443. The rotation assembly 460 is connected to the displacement slider 445. The displacement cylinder 441 pushes the displacement slider 445 to move under the guidance of the displacement rail 443. The displacement slider 445 can move toward the multi-core wire or away from the multi-core wire. During the movement, the displacement slider 445 drives the rotation assembly 460 to slide, and the rotation assembly 460 drives the clamping assembly 480 to slide.

[0066] The rotating assembly 460 includes a rotating motor 461, a coupling 463 and a positioning column 465. The rotating motor 461 is connected to the displacement assembly 440, the coupling 463 is connected to the output end of the motor, the positioning column 465 is connected to the coupling 463, the positioning column 465 is used to be inserted into the multi-core wire, the clamping assembly 480 is connected to the positioning column 465, the clamping assembly 480 is used to press the multi-core wire onto the positioning column 465, and the rotating motor 461 is used to drive the positioning column 465 to rotate a preset angle.

[0067] In order to enable those skilled in the art to have a further understanding of the technical solution of the present invention, the following will be explained with specific implementation methods. 1. The displacement assembly 440 pushes the positioning column 465 toward the multi-core wire and inserts it into the multi-core wire; 2. The clamping assembly 480 presses the multi-core wire onto the positioning column 465; 3. The rotating motor 461 drives the coupling 463 to rotate, and the coupling 463 drives the positioning column 465 to rotate. The positioning column 465 drives the clamping assembly 480 and the multi-core wire to rotate around the axis of the positioning column 465 to a preset angle so that the multi-core wire has the same shape as the joint weld foot; 4. The displacement assembly 440 pushes the positioning column 465 away from the multi-core wire, and the clamping assembly 480 and the rotating assembly 460 move together to straighten and shape the multi-core wire. The positioning column 465 acts as a central axis to support the multi-core wire to drive the multi-core wire to rotate precisely.

[0068] The circumferential surface of positioning post 465 is formed with multiple grooves 467, each of which is used to accommodate a core of the multi-core wire, thereby separating the multiple cores. The function of clamping assembly 480 is to enclose each core in groove 467, so that the multi-core wire rotates with positioning post 465. Furthermore, the end of positioning post 465 is provided with a chamfer, which can be either beveled or rounded, to facilitate the sliding of the multi-core wire into the multiple grooves 467.

[0069] See also Figures 10 to 13 , Figure 12 is a cross-sectional schematic diagram of the correction module 400 provided by the present invention, Figure 13 yes Figure 12 Schematic diagram of the enlarged area D in FIG.

[0070] The clamping assembly 480 includes a first turntable 481, a second turntable 482, a plurality of clamping members 483, a plurality of deformation springs 484 and a first cylinder 485. The first turntable 481 is connected to the positioning column 465, and the second turntable 482 is slidingly connected to the first turntable 481. A plurality of clamping members 483 are distributed on the first turntable 481 and inserted into the second turntable 482. The clamping member 483 is used to press the multi-core wire onto the positioning column 465. One end of the deformation spring 484 is connected to the clamping member 483, and the other end is connected to the first turntable 481. The first cylinder 485 is connected to the second turntable 482. The output end of the first cylinder 485 is connected to the first turntable 481. The first cylinder 485 is used to push the second turntable 482 toward the first turntable 481 so that the second turntable 482 squeezes the clamping member 483 to move toward the positioning column 465.

[0071] In order to enable those skilled in the art to have a further understanding of the technical solution of the clamping assembly 480 of the present invention, the following will be explained using a specific implementation method. 1. The first air cylinder 485 is activated to pull the first turntable 481 and the second turntable 482 closer together; 2. The second turntable 482 squeezes the clamping member 483 toward the positioning column 465, pressing the multi-core wire onto the positioning column 465, and the deformation spring 484 is in a compressed state; 3. The first air cylinder 485 is activated to push the first turntable 481 and the second turntable 482 farther apart, the second turntable 482 no longer squeezes the clamping member 483, and the deformation spring 484 recovers its deformation, pushing the clamping member 483 away from the multi-core wire. Of course, in other embodiments, the clamping assembly 480 can also directly use the clamping member 483 air cylinder to clamp the multi-core wire onto the positioning column 465.

[0072] The clamping member 483 includes a first slider 491, a second slider 492, and a first compression spring 493. The first slider 491 is slidably connected to the first rotary disk 481 and inserted into the second rotary disk 482. One end of the deformation spring 484 is connected to the first slider 491, and the other end is connected to the first rotary disk 481. The second slider 492 is slidably connected to the first rotary disk 481. One end of the first compression spring 493 is connected to the first slider 491, and the other end is connected to the second slider 492. When the second rotary disk 482 moves toward the first rotary disk 481, the second rotary disk 482 squeezes the first slider 491, and the first slider 491 simultaneously squeezes the deformation spring 484 and the first compression spring 493. The first compression spring 493 pushes the second slider 492 toward the multi-core wire, thereby pressing the multi-core wire against the positioning column 465. The first compression spring 493 and the first slider 491 cooperate together to elastically compress the multi-core wire. The first compression spring 493 plays a buffering role, thereby preventing the first slider 491 from crushing the multi-core wire.

[0073] A receiving groove 496 is formed at the end of the second slider 492 for accommodating the cores of the multi-core wire. The second slider 492 is used to position the multi-core wire on the positioning post 465. When the second slider 492 abuts the positioning post 465, the receiving groove 496 and the groove 467 close together to form a hole-like structure to accommodate the individual cores of the multi-core wire.

[0074] The clamping member 483 also includes a third slider 494 and a second compression spring 495. The third slider 494 is slidingly connected to the first turntable 481. The third slider 494 is located between the second slider 492 and the first turntable 481. The length of the second compression spring 495 is greater than the length of the first compression spring 493. One end of the second compression spring 495 is connected to the first slider 491, and the other end is connected to the third slider 494. The third slider 494 is used to press the multi-core wire onto the positioning column 465. When the second turntable 482 moves toward the first turntable 481, the second turntable 482 squeezes the first slider 491, and the first slider 491 squeezes the deformation spring 484, the first compression spring 493 and the second compression spring 495 at the same time. The first compression spring 493 pushes the second slider 492 and the third slider 494 to move toward the multi-core wire. Because the length of the second compression spring 495 is greater than the length of the first compression spring 493, the second slider 492 is subjected to a large thrust. The second slider 492 will first press the multi-core wire onto the fiber paper on the positioning column 465, and then the third slider 494 will press the multi-core wire onto the positioning column 465.

[0075] Clamping assembly 480 also includes a second cylinder 486, which is connected to coupling 463. The output end of second cylinder 486 is connected to first rotary disk 481. Second cylinder 486 is used to push first rotary disk 481 toward the multi-core wire, which in turn drives clamping assembly 480 toward the multi-core wire. In the initial state, a certain clearance is maintained between first rotary disk 481 and the end of positioning post 465. Similarly, a certain clearance is maintained between clamping assembly 480 and the end of positioning post 465. The end of positioning post 465 is preferentially inserted into the multi-core wire, causing the multi-core wire to droop over positioning post 465, thus preventing clamping assembly 480 from interfering with the multi-core wire.

[0076] See also Figure 14 and Figure 15 , Figure 14 is a structural diagram of the feeding module 500 provided by the present invention, Figure 15 yes Figure 14 Schematic diagram of the enlarged area E in FIG.

The purpose of rotating the joint by the compensation angle is to make the pins of the joint correspond one by one with the multiple core wires of the multi-core wire, thereby facilitating the soldering module 200 to perform automated soldering. The compensation angle is determined by comparing the actual connector with the standard connector, and can be 1 degree, 5 degrees, 12 degrees, 20 degrees, 30 degrees, 45 degrees, etc. It can be understood that after the connector is rotated at the compensation angle, the pins of the connector correspond one-to-one with the multiple core wires of the multi-core wire.

The data processing module of the light and shadow assembly 550 is used to compare the photographed result with a photo of a standard joint to determine the angle at which the joint needs to be rotated, and then send an adjustment instruction to the fine-tuning assembly 540. After receiving the adjustment instruction, the fine-tuning assembly 540 is used to drive the joint to rotate the compensation angle. Of course, in other embodiments, the compensation angle of rotation can be obtained by physical comparison or by visual comparison.

[0080] The material picking assembly 530 also includes a first material picking cylinder 531, a material picking slide 532, a material picking slider 533 and a second material picking cylinder 534.

The second material picking cylinder 534 is connected to the material picking slider 533. The second material picking cylinder 534 is used to clamp the joint from the feeding assembly 520. During normal operation, 1. the first picking cylinder 531 pushes the picking slider 533 to move along the picking rail 532 toward the feeding assembly 520, and the picking slider 533 drives the second picking cylinder 534 to move; 2. the second picking cylinder 534 clamps the joint from the feeding assembly 520; 3. the first picking cylinder 531 pushes the picking slider 533 to move along the picking rail 532 toward the fine-tuning assembly 540, and the picking slider 533 drives the second picking cylinder 534 to move; 4. the second picking cylinder 534 places the joint on the fine-tuning assembly 540.

The second partition 413 is connected to and penetrates the first partition 412, and is connected to the locking sleeve 415.
