A rotating wire breaking structure

Abstract

This utility model discloses a rotating wire breaking structure, comprising: a side plate with a through hole for a copper wire and a magnetic ring to pass through; a magnetic ring positioning mechanism disposed on one side of the side plate and used to clamp the magnetic ring passing through the through hole; a fixed clamping mechanism and a rotating clamping mechanism disposed between the magnetic ring positioning mechanism and the side plate, with the rotating clamping mechanism located on the side of the fixed clamping mechanism closer to the side plate. Both the fixed clamping mechanism and the rotating clamping mechanism are used to clamp the copper wire passing through the through hole, and the rotating clamping mechanism is also used to rotate the copper wire around the through hole. The copper wire breaks through the torsional action of the rotating clamping mechanism, using torsional stress instead of traditional tensile tension to achieve wire breaking. This reduces excessive tensile damage caused by the elastic deformation of the copper wire, protecting the internal structure and surface integrity of the copper wire, and is especially suitable for copper wires with a high elastic modulus.

Description

Technical Field

[0001] This application relates to apparatus or methods for manufacturing magnetic cores, coils or magnets, and more particularly to a rotating wire breakage structure. Background Technology

[0002] During the manufacturing process of the T1 coil, after the winding process is completed, the excess copper wire on the coil needs to be cut off to meet the process requirements of subsequent processes such as wire splitting and stranding. The key to the wire cutting operation is to ensure that the excess copper wire is completely broken off while avoiding damage to the already wound coil and the remaining copper wire tails. Therefore, the rationality and reliability of the wire cutting structure are crucial to product quality.

[0003] The patent document with announcement number CN211719428U describes a T1 wire breaking structure, which achieves wire breaking through the cooperation of a magnetic attracting component and a wire breaking block. Its working principle is that the wire pressing block and the wire pressing base close together to press the copper wire tail of the magnetic ring. The cylinder moves the magnetic attracting cylinder, the opening of the magnetic attracting cylinder and the magnetic ring on the magnetic attracting base backward. Since the magnetic ring moves backward with the magnetic attracting cylinder, the excess tail of the magnetic ring is pressed down by the wire breaking block and cannot move with it. Therefore, the excess copper wire tail of the magnetic ring will be broken off at the pre-cut wire breaking point.

[0004] However, existing wire breaking structures based on tension have significant drawbacks: because copper wire itself has a certain elastic deformation capacity, during the process of breaking the wire by tension, the copper wire will undergo tensile deformation due to continuous tension. When the tension exceeds the copper wire's bearing limit, although the wire can be broken, the copper wire will experience stress changes due to the release of elastic potential energy at the moment of breakage. This can easily lead to internal structural damage or appearance defects in the copper wire near the break. Such damage or defects may not only affect the conductivity of the copper wire, but also reduce the overall mechanical strength and service life of the coil.

[0005] Therefore, how to ensure the wire breakage effect while avoiding damage caused by the elasticity of the copper wire has become a technical problem that needs to be solved in the existing T1 wire breakage structure. Utility Model Content

[0019] Reference Figure 1-5 This application presents an embodiment of a rotating wire breaking structure, characterized in that it comprises: Side plate 10, wherein the side plate 10 is provided with through holes 11 for copper wires and magnetic rings to pass through; A magnetic ring positioning mechanism 30 is disposed on one side of the side plate 10 and is used to clamp the magnetic ring passing through the through hole 11; A fixed clamping mechanism 40 and a rotating clamping mechanism 50 are disposed between the magnetic ring positioning mechanism 30 and the side plate 10, and the rotating clamping mechanism 50 is located on the side of the fixed clamping mechanism 40 closer to the side plate 10. Both the fixed clamping mechanism 40 and the rotating clamping mechanism 50 are used to clamp the copper wire passing through the through hole 11. The rotating clamping mechanism 50 is also used to clamp the copper wire and rotate it around the through hole 11.

[0020] The working principle of the rotating wire-breaking structure described in this embodiment is as follows: The wound magnetic ring is passed through the through hole 11 of the side plate 10, and the magnetic ring positioning mechanism 30 clamps and fixes the magnetic ring passing through the through hole 11; subsequently, the fixed clamping mechanism 40 and the rotating clamping mechanism 50 respectively clamp and tighten the copper wire between the through hole 11 and the magnetic ring, and distribute the pre-breaking cut between the fixed clamping mechanism 40 and the rotating clamping mechanism 50; finally, the rotating clamping mechanism 50 applies a rotational force to the clamped copper wire with the through hole 11 as the center, so that the copper wire between the fixed clamping mechanism 40 and the rotating clamping mechanism 50 generates torsional stress. When the torsional stress reaches the breaking limit of the copper wire, the copper wire breaks between the two clamping mechanisms, completing the wire-breaking operation. After the wire is broken, the magnetic ring positioning mechanism 30, the fixed clamping mechanism 40 and the rotating clamping mechanism 50 are released, the broken magnetic ring at the magnetic ring positioning mechanism 30 is removed, and the broken wire at the through hole 11 is cleaned up in order to perform the next wire-breaking operation.

[0021] The copper wire is broken at the pre-cutting point by the torsional action of the rotating clamping mechanism 50. The torsional stress is used to replace the traditional tensile tension to achieve wire breakage, which can reduce tensile damage caused by elastic deformation of the copper wire and protect the internal structure and surface integrity of the copper wire. It is especially suitable for copper wires with high elasticity coefficient. The rotation angle of the rotating clamping mechanism 50 can be flexibly adjusted according to the copper wire material, diameter and other parameters to meet the wire breakage requirements of copper wires of different specifications.

[0022] Specifically, the magnetic ring positioning mechanism 30 includes a base, a telescopic cylinder 31, a magnetic adsorption component 32, and a wire clamping mechanism 33. The telescopic cylinder 31 is mounted on the base with its telescopic end facing the side plate 10. The magnetic adsorption component 32 is mounted on the telescopic end of the telescopic cylinder 31. The wire clamping mechanism 33 is disposed on the base and located on the side of the magnetic adsorption component 32 near the side plate 10.

[0023] After the wound magnetic ring and copper wire pass through the through hole 11 of the side plate 10, the telescopic end of the telescopic cylinder 31 extends, allowing the magnetic adsorption component 32 to approach and adsorb the magnetic ring passing through the through hole 11, thus achieving the initial positioning of the magnetic ring. Subsequently, the wire clamping mechanism 33 clamps the copper wire between the magnetic adsorption component 32 and the side plate 10, further fixing the position of the copper wire. The telescopic cylinder 31 shortens and clamps the magnetic ring away from the side plate, so that the copper wire between the magnetic ring and the side plate 10 is in a taut state. After the fixed clamping mechanism 40 and the rotating clamping mechanism 50 clamp, rotate, and complete the wire breaking operation, the wire clamping mechanism 33 releases the copper wire and removes it from the magnetic adsorption component 32, separating it from the magnetic ring.

[0024] The magnetic adsorption component 32 uses magnetic force to adsorb the magnetic ring. Combined with the telescopic action of the telescopic cylinder 31, it can quickly and stably position magnetic rings of different specifications, preventing the magnetic ring from shifting during translation or wire breakage, and ensuring the accuracy of subsequent operations. The wire clamping mechanism 33 clamps the copper wire on the side of the magnetic adsorption component 32 near the side plate 10. It works with the magnetic adsorption component 32 to form a double fixation for the magnetic ring and the copper wire, reducing the deviation of the wire breakage position caused by the shaking of the copper wire.

[0025] The wire clamping mechanism 33 includes two opposing clamping blocks and a telescopic rod that drives one of the clamping blocks to move. The telescopic rod pushes the clamping block to move closer to the other clamping block to close the wire clamping mechanism 33, or away from the other clamping block to open the wire clamping mechanism 33.

[0026] In another embodiment, the magnetic ring positioning mechanism 30 is mounted on a translation mechanism, which can adjust the distance between the magnetic ring positioning mechanism 30 and the side plate 10, and is suitable for broken wires of different lengths.

[0027] In this embodiment, the fixing clamping mechanism 40 is a finger cylinder.

[0028] Furthermore, the rotary clamping mechanism 50 includes a rotary drive assembly 51, a connector 52, a clamping drive assembly 53, and two clamping members 54. The connector 52 is mounted on the rotary drive assembly 51, and the two clamping members 54 are mounted on the connector 52 and located on both sides of the through hole 11. The two clamping members 54 can slide relative to each other on the connector 52. The clamping drive assembly 53 is used to drive the two clamping members 54 to slide relative to each other to open to release the copper wire, or to close to clamp the copper wire.

[0029] During the preparation stage of the wire breaking operation, the clamping drive assembly 53 drives the two clamping pieces 54 to slide relative to each other and open on the connector 52, leaving space for the copper wire to pass through. After the copper wire passes through the through hole 11 of the side plate 10 and is positioned by the fixed clamping mechanism 40, the clamping drive assembly 53 drives the two clamping pieces 54 to close, clamping and fixing the copper wire from both sides of the through hole 11. Subsequently, the rotation drive assembly 51 drives the connector 52 and the clamped copper wire to rotate around the through hole 11, causing torsional stress to be generated in the copper wire between the rotation clamping mechanism 50 and the fixed clamping mechanism 40. When the torsional stress exceeds the breaking limit of the copper wire, the copper wire breaks between the two clamping mechanisms, completing the wire breaking.

[0030] In one embodiment, the clamping drive assembly 53 is connected to two clamping members 54, and the rotation drive assembly 51 drives the clamping drive assembly 53 and the two clamping members 54 to rotate synchronously.

[0031] In this embodiment, preferably, the clamping drive assembly 53 includes an elastic element 531 and a telescopic element 532. The two ends of the elastic element 531 are respectively connected to two clamping elements 54. The telescopic element 532 is mounted on the side plate 10, and the telescopic end of the telescopic element 532 faces the side plate 10. The telescopic element 532 can extend and overcome the elastic tension of the elastic element 531 to drive the two clamping elements 54 to slide relative to each other and open, or the telescopic end of the telescopic element 532 can shorten and move away from the clamping elements 54, and the two clamping elements 54 slide relative to each other and close under the restoring force of the elastic element 531.

[0032] In the clamping drive assembly 53 with the above structure, the two clamping members 54 close and clamp the copper wire under the action of the elastic member 531. When the two clamping members 54 need to open, the telescopic member 532 overcomes the elastic tension of the elastic member 531 and drives the two clamping members 54 to slide relative to each other and open. The rotating clamping mechanism 50 can drive the two clamping members 54 to rotate through the connecting member 52.

[0033] In one embodiment, the telescopic member 532 may be configured as a single telescopic member 532, which drives a clamping member 54 to slide relative to another clamping member 54 so that the two clamping members 54 open or close. In this embodiment, there are two telescopic members 532, and the two clamping members 54 are slidably mounted on the connecting member 52. The two telescopic members 532 are respectively located on the opposite side of the two clamping members 54.

[0034] Referring to the attached drawings, the two clamping members 54 are the first clamping member 541 and the second clamping member 542, and the connecting member 52 is provided with a fixing groove 521; The first clamping member 541 is disposed on one side of the connector 52, and the first clamping member 541 is provided with a first guide groove 5411. The second clamping member 542 is disposed on the other side of the connector 52, and the second clamping member 542 is provided with a second guide groove 5421. The first clamping member 541 is provided with a first slider 5412, which passes through the fixed slide groove 521 and extends into the second guide slide groove 5421. The second clamping member 542 is provided with a second slider 5422, which passes through the fixed slide groove 521 and extends into the first guide slide groove 5411.

[0035] The first slider 5412 on the first clamping member 541 slides along the fixed groove 521 of the connecting member 52, while simultaneously moving within the second guide groove 5421 of the second clamping member 542; the second slider 5422 on the second clamping member 542 slides synchronously along the fixed groove 521 and moves within the first guide groove 5411 of the first clamping member 541. Through the constraint of the slider's movement trajectory by the fixed groove 521 and the guiding effect of the first and second guide grooves 5421, the two clamping members 54 form a symmetrical movement relationship.

[0036] In this embodiment, the rotary drive assembly 51 includes a driver 511, which is connected to the connector 52 via a gear transmission assembly 512.

[0037] The driver 511 is a motor. The first gear of the gear transmission assembly 512 is mounted on the drive shaft of the motor, and the second gear is rotatably mounted on the side plate 10. The connector 52 is mounted on the second gear. The transmission gear of the gear transmission assembly 512 meshes with the first gear and the second gear, so that the motor can drive the connector 52 through its drive shaft and the gear transmission assembly 512 to drive the two clamping members 54 to rotate and break the wire.

All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
