Description

Technical Field

[0001] This invention relates to the field of wire processing technology, specifically to a double-end twisting mechanism for battery wire production. Background Technology

[0002] With the rapid development of industries such as new energy vehicles, energy storage batteries, and portable electronic devices, battery connectors, as core conductive connectors, directly affect the performance and safety of end products due to their connection reliability, conductivity, and mechanical strength. In the production process of battery connectors, core twisting is one of the key steps. By spirally twisting multi-strand loose core wires, the core's tightness, fatigue resistance, and conductivity stability can be improved. This also facilitates subsequent terminal crimping or welding, reducing contact resistance and the risk of overheating.

[0003] In traditional equipment, the wire stripping and twisting processes are independent. First, the outer sheath of the connecting wire is cut and stripped using a wire stripping machine, and then the stripped connecting wire is transferred to a twisting machine for twisting. During this transfer, the exposed wire core is prone to fraying, delamination, or surface oxidation due to collisions and friction. This not only affects the tightness and uniformity of the twist but may also lead to poor contact at subsequent connection points. Furthermore, the separate processes increase manual intervention, reduce production efficiency, and make it difficult to ensure a precise match between the stripped length and the twisting position. Summary of the Invention

The mounting sleeve is slidably connected to the inside of the mounting block and fits against the side of the circumferential cutting blade. A tension spring is fixedly connected between the inner wall of the mounting sleeve near the push rod and the inner wall of the mounting block. A clamping block is fixedly connected to the side of the mounting sleeve away from the push rod.

[0009] Preferably, each set of driving components further includes two movable plates slidably connected to the inner wall of the connecting seat. Each of the two movable plates has a guide groove II on the side near the support seat. A lead screw is rotatably connected to the inner side of the support seat. The lead screw is fixedly connected to the outer side of the drive shaft. A push block is also slidably connected inside the support seat. The push block is threadedly connected to the lead screw. A push plate is slidably connected between the push block and the support seat. A spring I is fixedly connected between the side of the push plate away from the push block and the inner wall of the support seat. A connecting plate is fixedly connected to the side of the push block near the movable plate. Two fixing rods are fixedly connected to the side of the connecting plate near the movable plate. Both fixing rods are slidably connected inside the guide groove II.

[0010] Preferably, the slide block is provided with a slitting component inside. The slitting component includes sliding blocks symmetrically slidably connected inside the slide block. The slide block is also slidably connected with two connecting rods. The two connecting rods pass through and are fixedly connected to the interior of the two sliding blades at opposite ends. Both ends of the connecting rods are slidably connected to the interior of the guide groove. The two sliding blocks are fixedly connected to sliding blades at their adjacent ends. The end of the sliding blade closest to the movable sleeve is in contact with the sliding blade.

[0011] Preferably, the connecting seat is provided with a positioning component.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. By cooperating with dual motors and drive components, the gears and gear rings of the two sets of drive components are synchronously transmitted, so that the clamping force of the positioning block, the axial cutting depth of the slitting blade, the closing accuracy of the ring cutting blade and the twisting speed are precisely matched in time. This completely avoids the problems caused by the separation of the wire stripping and twisting processes in traditional equipment, such as the outer sheath and the core being separated, the core being loose or the surface being worn during the transfer of the connecting wire. This significantly improves the tightness and consistency of the core after twisting.

[0016] 2. The sliding fit between the guide groove of the movable sleeve and the fixed guide roller, through the structural design of the spiral groove section and the arc groove section, realizes the mechanical linkage conversion of rotation and axial feed. There is no need to set up an additional linear drive mechanism, which simplifies the transmission link, reduces the size of the equipment and energy consumption. At the same time, through the rolling friction between the guide roller and the groove wall, the transmission loss is reduced, the action response speed is improved, and the stability of twisting quality is further guaranteed.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 14 This invention provides a technical solution: a double-end twisting mechanism for battery connector production, including a device base 1, an operating table 2, and a mounting base 3. The mounting base 3 is mounted on the top of the device base 1 via the operating table 2. A twisting assembly 4 is provided at the bottom of the mounting base 3. The twisting assembly 4 includes a connecting seat 41, a movable sleeve 42, a twisting component 45, and a ring-cutting component 49. The connecting seat 41 is fixedly installed at the bottom of the mounting base 3. A slide seat 46 is slidably connected inside the connecting seat 41. A guide groove 421 is provided on the outer side of the movable sleeve 42. The guide groove 421 is composed of a spiral groove 422 and two arc grooves 423. The two arc grooves 423 are respectively connected to the two ends of the spiral groove 422. A guide roller 48 is fixedly connected to the bottom inner wall of the connecting seat 41. The top of the guide roller 48 is slidably installed inside the guide groove 421. When the twisting component 45 rotates, it will drive the movable sleeve 42 to rotate synchronously. The movable sleeve 42 is slidably connected to the guide roller 48 through the guide groove 421 opened on its outer side, so that when the movable sleeve 42 rotates, the fixed guide roller 48 pushes the groove wall of the guide groove 421 to push the movable sleeve 42 and the twisting component 45. Since the guide groove 421 is composed of a spiral groove 422 and two arc-shaped grooves 423, when the guide roller 48 is located in the arc-shaped groove 423, the rotation of the twisting component 45 cannot drive the movable sleeve 42 to move. When the guide roller 48 is located in the spiral groove 422, the rotation of the twisting component 45 drives the movable sleeve 42 to move, so that the spiral twisting of the wire core can be achieved by the annular cutting component 49 in the twisting component 45. The twisting component 45 includes a movable seat 451 rotatably connected to the slide 46 via an annular guide rail, so that when the twisting component 45 rotates and moves under the action of the movable sleeve 42, it can stably push the slide 46 to move and is not affected by the rotation. The movable sleeve 42 The movable base 451 is fixedly connected to the movable base 451 so that the movable base 451 can rotate and drive the movable sleeve 42 to rotate synchronously. The outer side of the movable base 451 is provided with an annular groove 452. Four movable blocks 454 are slidably connected inside the annular groove 452. The ring cutting component 49 is slidably installed inside the annular groove 452. By driving the movable blocks 454, the ring cutting component 49 can be pushed, so that the ring cutting component 49 can move to ring cut the outer sheath of the connecting wire, and then perform spiral rotation to twist the wire core. This reduces the interval between stripping and twisting, and avoids the problem that the connecting wire is delaminated due to collision and friction during transportation, which affects the twisting quality and efficiency, because traditional stripping and twisting are done separately. The movable sleeve 42, the movable seat 451, and the slide 46 all have circular grooves inside to facilitate the placement of connecting wires.

[0021] Two motors 5 are symmetrically fixed on the side of the slide block 46 away from the movable sleeve 42. The controller sends a clear reference command to the main motor 5, and the main motor 5 starts according to the command. At the same time, it feeds back its actual running status to the controller through the encoder. The controller directly uses the "actual running status" of the main motor 5 as the "reference command" of the slave motor 5. The slave motor 5 compares its own status with the feedback of the main motor 5 in real time, and eliminates the deviation through simple PID correction to achieve synchronization. Two sets of drive components 44 are symmetrically arranged between the twisting component 45 and the connecting seat 41, which work together with the dual motors 5 to ensure the stability of the drive of the movable sleeve 42 and the twisting component 45. Each set of drive components 44 includes a support seat 442 fixedly connected to the slide seat 46. A drive shaft 4410 is rotatably connected inside the support seat 442. The end of the drive shaft 4410 away from the movable sleeve 42 passes through the slide seat 46 and is fixedly connected to the output shaft of the motor 5. One end of the drive shaft 4410 located inside the support seat 442 is fixedly connected to a gear 4413. A gear ring 458 is fixedly connected to the outside of the four movable blocks 454. The gear ring 458 is rotatably connected inside the annular groove 452. The gear ring 458 and the gear 4413 mesh with each other. The motor 5 is fixedly connected to the drive shaft 4410 via the output shaft. The drive shaft 4410 can drive the gear 4413 fixedly connected thereon. Then, through the meshing between the gear 4413 and the gear ring 458, the gear ring 458 is pushed to rotate inside the annular groove 452. The gear ring 458 drives the four movable blocks 454 fixedly connected inside it to rotate.

[0022] The annular groove 452 is also fixedly connected to four fixed blocks 453. Four movable blocks 454 are slidably installed between two adjacent fixed blocks 453, so that the four fixed blocks 453 and the four movable blocks 454 are alternately distributed, so as to achieve uniform division of the internal space of the annular groove 452 and ensure the stability of the movement of the movable blocks 454. The four fixed blocks 453 are internally fixedly connected to guide rings 456. The outer side of the guide rings 456 located between two adjacent fixed blocks 453 is fixedly connected to baffles 457. The four movable blocks 454 are slidably installed between two adjacent fixed blocks 453 through the guide rings 456. Sliding the movable block 454 onto the outside of the guide ring 456 not only ensures the stability of the movable block 454's movement, but also limits the position of the movable block 454 through the baffle 457 fixedly connected to the outside of the guide ring 456. This prevents the toothed ring 458 from driving the movable block 454 to rotate to the desired angle, thus preventing it from further pushing the circumferential cutting component 49. Instead, the baffle 457, guide ring 456, and fixed block 453 drive the movable seat 451 to rotate, which in turn drives the movable sleeve 42 to rotate. With the sliding cooperation between the movable sleeve 42's outer guide groove 421 and the guide roller 48, the twisting component 45 and the movable sleeve 42 rotate and move. This allows for the simultaneous circumferential cutting of the outer sheath of the connecting wire between the circumferential cutting components 49 and the twisting of the stripped wire core.

[0023] The circumferential cutting component 49 includes a mounting block 491, a push rod 492, a circumferential cutting blade 493, and a mounting sleeve 494. The mounting block 491 is slidably connected to the inner side of the annular groove 452 and extends through to the inner side of the movable seat 451, so that the mounting block 491 can move into the movable seat 451 to perform circumferential cutting of the outer sheath and twisting of the wire core on the connecting wire inserted into the movable seat 451. The push rod 492 is rotatably connected between the movable block 454 and the mounting block 491, so that the movable block 454 can push the mounting block 491 to slide within the movable seat 451 through the push rod 492 during rotation. The circumferential cutting blade 493 is fixedly connected to the inside of the mounting block 491, and the circumferential cutting blade 493 is along the circumferential cutting direction. The end is provided with an inclined blade, which can be used to cut the outer sheath of the connecting wire through the ring cutter 493. The mounting sleeve 494 is slidably connected to the inside of the mounting block 491 and fits against the side of the ring cutter 493. The mounting sleeve 494 can be used to twist the wire core after the outer sheath is cut. A tension spring 496 is fixedly connected between the inner wall of the mounting sleeve 494 near the push rod 492 and the inner wall of the mounting block 491. A clamping block 495 is fixedly connected to the side of the mounting sleeve 494 away from the push rod 492, and the ring cutter 493 is located at the end of the clamping block 495 near the slide 46. The clamping block 495 can be moved towards the connecting wire by the tension of the tension spring 496.

[0024] Each set of drive components 44 also includes two movable plates 441 that are symmetrically slidably connected to the inner wall of the connecting seat 41. Each of the two movable plates 441 has a guide groove 443 on the side near the support seat 442. The guide groove 443 is composed of a horizontal groove and an oblique groove. A lead screw 447 is rotatably connected to the inner side of the support seat 442. The end of the lead screw 447 near the slide 46 is not provided with threaded teeth. The lead screw 447 is fixedly connected to the outer side of the drive shaft 4410. A push block 444 is also slidably connected inside the support seat 442. The push block 444 is threadedly connected to the lead screw 447. Since only a portion of the threaded teeth are provided on the outer side of the lead screw 447, when the drive shaft 4410 pushes the push block 444 towards the slide 46 a certain distance through the thread of the lead screw 447, it can no longer push the push block 444 to continue moving. A push plate 449 is slidably connected between the push block 444 and the support base 442. A spring 448 is fixedly connected between the side of the push plate 449 away from the push block 444 and the inner wall of the support base 442. When the push block 444 and the push plate 449 are in contact, the push block 444 moves and squeezes the push plate 449, so that the push plate 449 compresses the spring 448 to retract. When the drive shaft 4410 reverses and resets, the spring 448 pushes the push block 444 through the push plate 449 under the elastic action, ensuring that the push block 444 can reconnect with the lead screw 447 and then continue to move under the push of the thread. A connecting plate 445 is fixedly connected to the side of the push block 444 near the movable plate 441. Two fixed rods 446 are fixedly connected to the side of the connecting plate 445 near the movable plate 441. The fixed rods 446 are slidably connected inside the guide groove 443. When the push block 444 moves toward the slide block 46, the connecting plate 445 can drive the upper and lower fixed rods 446 to move. Since the fixed rods 446 are slidably connected to the guide groove 443 on the movable plate 441, and the movable plate 441 is located in the inclined groove part of the guide groove 443 at this time, the moving fixed rods 446 will push the movable plate 441 to move along the inner wall of the connecting seat 41 through the inclined groove of the guide groove 443.

[0025] The slide block 46 is internally equipped with a cutting component 47, which can cut the outer sheath of the connecting wire vertically. At this time, the clamping block 495 will be pressed against the outer sheath under the tension of the tension spring 496, and the cut part will be clamped at close range, reducing the impact of the separation of the wire core and the outer sheath during the circumferential cutting process on the circumferential cutting effect. The cutting component 47 includes a cutting block 471 symmetrically slidably connected inside the slide block 46. The cutting block 471 slides up and down along the slide block 46. The slide block 46 is internally provided with symmetrical through slots. Two connecting rods 472 are also slidably connected inside the slide block 46. The two connecting rods 472 are slidably installed in the two through slots respectively, and the two connecting rods 472 pass through and are fixedly connected. Inside the two slitting blades 473 at their far ends, both ends of the connecting rod 472 are slidably connected to the inside of the guide groove 443. The two slitting blocks 471 at their close ends are fixedly connected to the slitting blades 473. The end of the slitting blade 473 near the movable sleeve 42 is in contact with the slitting blade 473. When the movable plate 441 moves under the push of the fixed rod 446, the connecting rod 472 slidably connected to the slitting blade 473 will move synchronously. The movement of the connecting rod 472 drives the slitting block 471 to move, so that the slitting block 471 can axially cut the outer sheath of the connecting wire through the slitting blade 473 fixedly connected to it. The axial cutting and circumferential cutting are combined to ensure the connection of the cut and facilitate the removal of the outer sheath.

[0026] The connector 41 has a positioning component 43 inside, which clamps and fixes the connecting wire within the connector 41, preventing the connecting wire from moving synchronously when the twisting component 45 twists the wire core through the circumferential cutting component 49. The positioning component 43 includes two positioning seats 431 symmetrically fixed to the inner wall of the connector 41, providing support for the movement of the positioning block 432 and ensuring the stability of the movement of the positioning block 432. The positioning block 432 is slidably connected inside the two positioning seats 431, and clamping grooves are opened at the adjacent ends of the two positioning seats 431. The inner side of the positioning block 432 is fixedly connected to... The connecting block 433 is slidably connected to the inside of the positioning seat 431, and both ends of the connecting block 433 are fixedly connected to two sets of movable plates 441 respectively. When the two movable plates 441 in each set move towards each other, they will drive the upper and lower connecting blocks 433 to move synchronously. The connecting block 433 clamps and positions the connecting line through the positioning block 432. By sliding the positioning block 432 inside the positioning seat 431, the clamping load of the movable plate 441 is reduced while ensuring stable clamping. This allows the movable plate 441 to use the minimum force to drive the clamping and reduces the stress between the movable plate 441 and the fixed rod 446.

[0027] A second spring 455 is fixedly connected between the movable block 454 and the fixed block 453. The second spring 455 is sleeved on the outside of the guide ring 456. The elastic force of the second spring 455 can achieve stable support for the movable block 454 inside the movable seat 451, ensuring the stability of the movable block 454 sliding outside the guide ring 456.

[0028] Two sliders 4412 are symmetrically fixedly connected to the side of the movable plate 441 away from the movable sleeve 42. The inner wall of the movable plate 441 is provided with a groove 4411 that matches the support seat 442. The sliders 4412 are slidably connected inside the groove 4411, thereby ensuring the stability of the sliding connection between the movable plate 441 and the inner wall of the connecting seat 41, so that the movable plate 441 can slide up and down more stably on the inner wall of the connecting seat 41.

[0029] Four limiting strips 462 are fixedly connected to the inner wall of the connecting seat 41, and four straight grooves 461 are opened on the outer side of the slide 46. The limiting strips 462 and the straight grooves 461 are slidably connected to each other, thereby ensuring the stability of the slide 46 sliding inside the connecting seat 41.

[0030] In actual use, when the mechanism is not started, each component is in the initial reset state: the guide roller 48 is engaged with the arc groove 423 section of the guide groove 421 of the movable sleeve 42, and the movable sleeve 42 and the twisted wire component 45 have no axial displacement. Spring 1 (448), Spring 2 (455), and tension spring 496 are all in their naturally extended state. Positioning block 432 is in the open state, slitting blades 473 are separated from each other, and ring cutting blade 493 and clamping block 495 are away from the connecting line channel; The dual motor 5 is in a stopped state, the controller does not send a drive command, and the push block 444 is fully engaged with the threaded section of the lead screw 447. Connector positioning and axial cutting stage: Insert the battery connection wire to be processed into the internal channel of the movable seat 451, pass through the clamping groove of the positioning seat 431, until the part of the wire core to be twisted corresponds to the ring cutting component 49, and the outer sheath covers the working area of ​​the cutting component 47. The controller sends a start command to the main motor 5, and the main motor 5 drives the drive shaft 4410 to rotate through the output shaft. One of the drive shafts 4410 drives the gear 4413 and the lead screw 447 fixed on its outer side to rotate synchronously. The lead screw 447 is threadedly engaged with the push block 444, pushing the push block 444 to move along the support base 442 towards the slide block 46. The push block 444 drives the two fixed rods 446 to move towards the slide block 46 via the connecting plate 445. Figure 5The left side moves; the fixed rod 446 is slidably connected to the guide groove 443 inclined groove section of the movable plate 441, and the inclined groove guides the upper and lower movable plates 441 to slide towards each other along the sliding groove 4411 on the inner wall of the connecting seat 41; the movable plate 441 drives the positioning block 432 to slide along the inner side of the positioning seat 431 through the connecting block 433 until the clamping groove of the positioning block 432 is tightly fitted with the outer sheath of the connecting line, thereby achieving axial positioning of the connecting line and preventing movement during processing; When the movable plate 441 moves, the guide groove 443 synchronously drives the connecting rod 472 to move horizontally. The connecting rod 472 drives the cutting blocks 471 to slide towards each other along the inside of the slide block 46. The cutting blocks 471 drive the cutting blades 473 to move closer together. The cutting edges of the cutting blades 473 cut into the outer sheath of the connecting wire, completing the axial cutting and facilitating the removal of the outer sheath. Figure 12 As shown, at this time, the push block 444 moves away from the threaded section of the lead screw 447. The push block 444 can no longer move along the lead screw 447, and instead squeezes the push plate 449 and compresses the spring 448, so that the positioning and cutting action is in place and maintained. During the outer skin ring cutting stage, the fixed guide roller 48 slides within the arc-shaped groove 423 on the guide groove 421: Please refer to Figure 12 The drive shaft 4410 rotates, which drives the gear 4413 fixed at its end to rotate. The gear 4413 meshes with the gear ring 458 to drive the gear ring 458 to rotate in the annular groove 452 of the movable seat 451. Since the force required to move the movable block 454 and compress the second spring 455 is much less than the force required to rotate the movable sleeve 42, the gear ring 458 drives the four movable blocks 454 fixed on the inner side to slide along the outer side of the guide ring 456 within the limited space between the adjacent fixed blocks 453. The movable block 454 compresses the second spring 455 to accumulate elastic potential energy. The movable block 454 pushes the mounting block 491 to slide along the annular groove 452 towards the inner side of the movable seat 451 through the push rod 492. The mounting block 491 drives the internally fixed ring cutter 493 to move closer synchronously. The four circumferential cutting blades 493 close together, contact the outer sheath of the connecting wire, and complete the circumferential cut through the inclined cutting edge set at one end of the circumferential cutting direction. The circumferential cut is connected to the axial cut of the slitting blade 473, such as... Figure 7 and Figure 8 As shown, at this time, the movable block 454 rotates until it engages with the baffle 457 on the guide ring 456; please also refer to... Figure 10 The tension spring 496 pushes the mounting sleeve 494, causing the clamping block 495 to fit against the outer sheath of the connecting wire, thereby achieving close-range clamping of the circumferential section and reducing the impact of the separation of the wire core and outer sheath during the circumferential cutting process on the circumferential cutting effect. During the synchronous twisting stage, the fixed guide roller 48 slides within the spiral groove 422 on the guide groove 421: like Figure 7and Figure 8 As shown, as the movable block 454 rotates to engage with the baffle 457 on the guide ring 456, the baffle 457 restricts the movable block 454 from sliding further; at this time, the rotational force of the gear ring 458 is transmitted to the guide ring 456 through the baffle 457, and the guide ring 456 drives the movable seat 451 to rotate through the fixed block 453. The movable seat 451 is fixedly connected to the movable sleeve 42, driving the movable sleeve 42 to rotate synchronously; the guide groove 421 of the movable sleeve 42 is slidably engaged with the fixed guide roller 48, and the spiral groove 422 section generates axial thrust, driving the movable sleeve 42, the movable seat 451 and the slide 46 along the connecting seat 41 as... Figure 4 As shown, the device moves to the left, and the limiting strip 462 cooperates with the straight groove 461 to ensure smooth movement. During this process, the pressing block 495 moves with the ring cutter 493 under the tension of the tension spring 496. Since the outer sheath has already been axially cut at this time, the outer sheath can be pushed off the wire core during the movement of the ring cutter 493, exposing the wire core. Initially, the clamping block 495 contacts the outer sheath, and the movable sleeve 42 drives the clamping block 495 to move. Under the action of the tension spring 496, the mounting sleeve 494 drives the clamping block 495 to move close to the wire core. After the clamping block 495 is in contact with the wire core, it clamps the wire core by friction; the movable seat 451 rotates continuously, driving the wire core to twist in a spiral motion, thus achieving wire twisting; at the same time, the dual motors 5 ensure consistent action through a synchronous control algorithm: the main motor 5 feeds back the actual operating status through the encoder, and the controller uses this status as a reference command for the slave motor 5. The slave motor 5 eliminates deviations through PID correction, ensuring that the gears 4413 of the two sets of drive components 44 drive the gear ring 458 synchronously, avoiding uneven wire twisting or force deviation. Mechanism reset phase: When the wire twist reaches the preset number of turns or the axial displacement is in place, the controller receives the encoder feedback signal and sends a reverse command to the dual motors 5. Motor 5 reverses, driving drive shaft 4410 and lead screw 447 to reverse. Spring 448 elastically resets and pushes push plate 449. Push plate 449 drives push block 444 to reset and re-engage with lead screw 447. Push block 444 drives movable plate 441 to slide in the opposite direction through connecting plate 445 and fixed rod 446. Movable plate 441 drives positioning block 432 to open through connecting block 433. At the same time, connecting rod 472 drives sliding block 471 and slitting blade 473 to separate and reset. The reverse rotation of the drive shaft 4410 drives the gear 4413 and the gear ring 458 to reverse, and the movable block 454 is reset under the elastic action of the second spring 455. The push rod 492 pulls the mounting block 491 and the ring cutter 493 back to the initial position. The reverse rotation of the movable seat 451 drives the movable sleeve 42 to reset, and the guide roller 48 is re-engaged into the arc groove 423 section of the guide groove 421. The slide 46 is reset along the axial direction of the connecting seat 41. After the mechanism is fully reset, the robotic arm removes the processed twisted wire, and the controller waits for the next start command to enter the next processing cycle. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
