Description

Technical Field

[0001] This utility model relates to the field of transformer processing technology, specifically to an automatic transformer winding machine. Background Technology

[0002] In the transformer winding process, before winding the transformer frame, two bushing sections need to be pre-installed on the conductor. When winding the transformer frame, the first bushing section and the first end of the conductor are fixed to the first end of the transformer frame. The conductor is then wound around the transformer frame to a fixed length, and subsequently cut. Finally, the second bushing section and the second end of the cut conductor are fixed to the second end of the transformer frame. All of the above transformer winding operations are completed by an automatic transformer winding machine. However, existing automatic transformer winding machines have the following shortcomings:

[0003] When the diameter of the wound wire changes, the wire feeding assembly of the wire feeding mechanism (including two first rollers, forming a wire passage between the two first rollers, with a first gear on the first roller, and the two first gears meshing with each other) needs to be replaced. Furthermore, since the diameter of the guide tube needs to match the diameter of the wire, the tube feeding assembly of the guide tube feeding mechanism also needs to be replaced (including two second rollers, forming a tube passage between the two second rollers, with a second gear on the second roller, and the two second gears meshing with each other). Simultaneously, the clamping assembly of the tube cutting mechanism used to clamp the guide tube (including two clamping blocks, each with a semi-circular tube groove, the grooves of the two clamping blocks forming a circular hole) also needs to be replaced synchronously. This results in significant difficulty and time-consuming equipment adjustments when the winding diameter of the automatic winding machine changes. Additionally, multiple sets of wire feeding assemblies, tube feeding assemblies, and clamping assemblies are required, increasing manufacturing and operating costs and leading to a poor user experience. Summary of the Invention

[0004] To address the aforementioned issues, the main objective of this invention is to provide an automatic transformer winding machine that can more quickly adapt to changes in conductor diameter, thereby reducing debugging time, lowering costs, and offering high practicality.

[0005] To achieve the main objective of this utility model, it provides an automatic transformer winding machine, comprising a frame, a bushing conveying mechanism, a conductor conveying mechanism, and a bushing cutting mechanism. The bushing conveying mechanism includes a first drive roller rotatably mounted on the frame, a first drive unit driving the first drive roller, a first auxiliary wheel rotatable about its own axis, and a guide sleeve mounted on the frame. The extension line of the guide sleeve passes through a first clamping position formed between the first auxiliary wheel and the first drive roller, and the axial distance between the first auxiliary wheel and the first drive roller is adjustable. The conductor conveying mechanism includes a second drive roller rotatably mounted on the frame, a second drive unit driving the second drive roller, a second auxiliary wheel rotatable about its own axis, and a conductor sleeve mounted on the frame. The second drive roller is distributed along the axial direction of the first drive roller and parallel to the first drive roller. The extension line of the guide sleeve passes through the second clamping position formed between the second auxiliary wheel and the second drive roller. The axial distance between the second auxiliary wheel and the second drive roller is adjustable. The tube cutting mechanism includes a sliding seat slidably connected to the frame, a clamping assembly, a cutter located above the clamping assembly, a third drive unit mounted on the frame and driving the sliding seat to slide parallel to the axial direction, and a fourth drive unit and a fifth drive unit mounted on the sliding seat. The clamping assembly includes two clamping blocks arranged in a mirror image. The clamping blocks are provided with V-shaped grooves that penetrate themselves and are parallel to the guide sleeve. The fourth drive unit is used to drive the two clamping blocks to approach or separate. The fifth drive unit is used to drive the cutter to move relative to the clamping assembly.

[0006] As can be seen from the above, the bushing conveying mechanism can adjust the distance between the first auxiliary wheel and the first drive roller according to the diameter of the bushing, so that the bushing conveying mechanism can adapt to the bushing after the size specification has been changed; the wire conveying mechanism can adjust the distance between the second auxiliary wheel and the second drive roller according to the wire diameter, so that the wire conveying mechanism can adapt to the wire after the size specification has been changed; the tube cutting mechanism can adapt to the bushing after the size specification has been changed through the V-groove on the clamping block and the drive stroke of the fourth drive mechanism. Therefore, the above design can adapt to changes in the size of the wire and the bushing by adjusting the position of the first auxiliary wheel, the position of the second auxiliary wheel, and the moving position of the clamping block, so that there is no need to configure multiple sets of matching components for the automatic transformer winding machine. This saves manufacturing, use, and maintenance costs, and eliminates the need to replace matching components. It can more quickly complete the adjustment of the bushing conveying mechanism, the wire conveying mechanism, and the tube cutting mechanism, making the automatic transformer winding machine adaptable to wires and bushings with changed size specifications, and thus has greater practicality.

[0007] A preferred embodiment is that the frame includes a base plate, on which are provided a first groove, a second groove, a first strip groove, and a second strip groove parallel to the vertical line between the axis of the first auxiliary wheel and the first drive roller. The first strip groove is located at the bottom of the first groove and passes through the base plate, and the second strip groove is located at the bottom of the second groove and passes through the base plate. The sleeve conveying mechanism further includes a first slide and a first locking member. The first slide is slidably connected to the first groove, the first auxiliary wheel is mounted on the first slide, and the first locking member passes through the first strip groove and is connected to the first slide. The wire conveying mechanism further includes a second slide and a second locking member. The second slide is slidably connected to the second groove, the second auxiliary wheel is mounted on the second slide, and the second locking member passes through the second strip groove and is connected to the second slide.

[0008] As can be seen from the above, by adjusting the tightness of the first locking member and cooperating with the first slide and the first slide groove, the position of the first auxiliary wheel can be quickly adjusted, enabling the sleeve conveying mechanism to quickly adapt to the new size and specification of the sleeve; similarly, by adjusting the tightness of the second locking member and cooperating with the second slide and the second slide groove, the position of the second auxiliary wheel can be quickly adjusted, enabling the wire conveying mechanism to quickly adapt to the new size and specification of the wire.

[0009] A further embodiment is that a first elastic element is provided between the first locking member and the seat plate, and the first elastic element forces the first carriage to drive the first auxiliary wheel to move toward the first drive roller; a second elastic element is provided between the second locking member and the seat plate, and the second elastic element forces the second carriage to drive the second auxiliary wheel to move toward the second drive roller.

[0010] As can be seen from the above, the first locking member can appropriately lock the first slide but does not restrict the sliding of the first slide relative to the first slide groove, so that under the action of the first elastic member, the first slide drives the first auxiliary wheel to have a constant tendency to move towards the first drive roller, thereby enabling the sleeve conveying mechanism to adapt to changes in sleeve size; similarly, the second locking member can appropriately lock the second slide but does not restrict the sliding of the second slide relative to the second slide groove, so that under the action of the second elastic member, the second slide drives the second auxiliary wheel to have a constant tendency to move towards the second drive roller, thereby enabling the wire conveying mechanism to adapt to changes in wire size.

[0011] Another preferred embodiment is that the first of the two clamping blocks is fixedly mounted on the sliding seat, and the fourth drive unit drives the second clamping block to move so that the two clamping blocks are brought closer or separated.

[0012] As can be seen from the above, this design simplifies the structure of the fourth drive unit and helps to more accurately align the center line of the clamping position formed by the V-groove of the two clamping blocks with the center line of the sleeve, while also simplifying the control of the fourth drive unit.

[0013] A further embodiment includes a sliding seat comprising a body and a first connecting seat mounted on the body, the body being connected to a third drive unit; the first connecting seat has a guide rail parallel to the vertical line between the axis of the first auxiliary wheel and the first drive roller, a third carriage is mounted on the guide rail, a second clamping block is mounted on the third carriage, and a fourth drive unit is connected to the third carriage; a third elastic element is provided between the third carriage and the sliding seat, the third elastic element forcing the third carriage to move toward the fourth drive unit.

[0014] As can be seen from the above, this design can further simplify the drive control of the fourth drive unit, so that only unidirectional control of the fourth drive unit is required (such as driving the second clamping block to move towards the first clamping block), without the need for bidirectional control of the fourth drive unit. The fourth drive unit can be reset under the action of the third elastic element.

[0015] A further improvement is that the body has a third groove parallel to the vertical line, which penetrates the body axially; the sliding seat also includes a third locking member, which passes through the third groove and connects to the first connecting seat.

[0016] As can be seen from the above, this design is more conducive to ensuring that the center line of the clamping position formed by the V-groove of the two clamping blocks is accurately aligned with the center line of the sleeve.

[0017] A further embodiment includes a pipe-cutting mechanism that also includes a pipe-connecting unit. The pipe-connecting unit includes a drive module, a second connecting seat, a rocker arm, and a detection sensor. The drive module is mounted on a sliding seat, and the second connecting seat is connected to the drive module. The rocker arm is rotatably mounted on the second connecting seat about an axis parallel to the axial direction. The first end of the rocker arm is provided with a counterweight. The drive module is used to drive the second connecting seat to move the rocker arm along a vertical line parallel to the axis between the first auxiliary wheel and the first drive roller, so that the second end of the rocker arm is located below the clamping assembly. The detection sensor is mounted on the second connecting seat, and the second end of the detection sensor is set towards the counterweight.

[0018] As can be seen from the above, the connecting unit can be used to receive the first section of the sleeve that has been cut off, preventing the first section of the sleeve from falling down. At the same time, it can also limit the first section of the sleeve so that the two sections of the sleeve can maintain a set distance. The design of the lifting plate of the connecting unit allows it to control the opening and closing of the two clamping blocks through the detection sensor after receiving the falling first section of the sleeve, so as to clamp and cut the other section of the sleeve. It also helps to determine whether both sections of the sleeve have been removed by the cutting mechanism.

[0019] A further embodiment of the automatic transformer winding machine includes a first operating arm mechanism, a second operating arm mechanism, and a winding mechanism. The first operating arm mechanism includes a sixth drive unit and a first operating end. The sixth drive unit is mounted on the frame and is used to drive the first operating end to move between the threading station and the winding station of the automatic transformer winding machine. The second operating arm mechanism includes a seventh drive unit, a second operating end, and a wire cutting unit. The seventh drive unit is mounted on the frame and is used to drive the second operating end to move between the threading station and the winding station. At the threading station, the wire sleeve, clamping assembly, first operating end, and second operating end are distributed sequentially. The wire cutting unit is installed at the second operating end. The winding mechanism includes an eighth drive unit and a winding end. The eighth drive unit is mounted on the frame and is used to drive the winding end to move between the winding station, the loading station, and the unloading station of the automatic transformer winding machine.

[0020] As can be seen from the above, the first operating arm mechanism, the second operating arm mechanism, and the winding mechanism work together with the bushing conveying mechanism, the wire conveying mechanism, and the tube cutting mechanism to pass the wire through the bushing, tie the first end of the wire to the first end of the first bushing, wind the wire around the transformer frame, cut the wire, and tie the second end of the wire to the second end of the second bushing, thereby completing the winding process of the transformer frame.

[0021] A further proposed solution is that the automatic transformer winding machine also includes an adhesive applicator mounted on the frame, and the eighth drive unit is used to drive the winding end to move to the adhesive applicator.

[0022] As can be seen from the above, the adhesive application mechanism is used in conjunction with the winding mechanism to wrap the conductors with tape after the transformer frame has been wound, in order to protect the conductors and realize the entire production process of the transformer.

[0023] A further proposed solution is to have a loading mechanism at the loading station and a unloading mechanism at the unloading station.

[0024] As can be seen from the above, the feeding mechanism is used to automatically feed the winding mechanism; the unloading mechanism can move the transformer that has completed production and processing to the next designated position. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0034] Example of an automatic transformer winding machine

[0035] Reference Figure 1 The automatic transformer winding machine 100 includes a frame 1, a bushing conveying mechanism 2, a wire conveying mechanism 3, a pipe cutting mechanism 4, a first operating arm mechanism 51, a second operating arm mechanism 52, a winding mechanism 6, an adhesive applicator 7, a feeding mechanism 81, and a discharging mechanism 82.

[0036] Combination Figures 2 to 4 The sleeve conveying mechanism 2 includes a first drive roller 21, a first carriage 22, a first auxiliary wheel 23, a first locking element 24, a first drive unit 25, and a guide sleeve 26. The first drive roller 21 is rotatably mounted on the frame 1 around its own axis; the first auxiliary wheel 23 is rotatably mounted on the first carriage 22 around its own axis. A first clamping position is formed between the first auxiliary wheel 23 and the first drive roller 21. The first clamping position is used to allow the sleeve to pass through and to properly clamp the sleeve so that the sleeve is driven to move toward the sleeve cutting mechanism 4 under the cooperation of the first drive roller 21 and the first auxiliary wheel 23.

[0037] The frame 1 has a base plate 11, on which a first sliding groove 111 is provided. The first sliding groove 111 extends through the base plate 11 in the direction of the extension of the perpendicular line between the axis of the first drive roller 21 and the axis of the first auxiliary wheel 23. The extension direction is perpendicular to the height direction of the frame 1 and the axial direction of the first drive roller 21 respectively. The first slide 22 is slidably connected to the first sliding groove 111. The base plate 11 also has a first strip groove 113. The first strip groove 113 is located at the bottom of the first sliding groove 111 and is parallel to the extension direction. The first strip groove 113 extends through the base plate 11 in the height direction.

[0038] The first locking member 24 passes through the first slot 113 from the bottom of the seat plate 11 and connects to the first slide 22. The first locking member 24 can lock the first slide 22 and the seat plate 11 to prevent the first slide 22 from sliding relative to the seat plate 11, thereby preventing the first auxiliary wheel 23 from moving relative to the first drive roller 21 and ensuring the reliability of the first drive roller 21 and the first auxiliary wheel 23 in conveying the sleeve. When it is necessary to adjust the relative position of the first auxiliary wheel 23 and the first drive roller 21, the first locking member 24 can be loosened appropriately to release the mutual fixation of the first slide 22 and the seat plate 11, thereby making the axial distance between the first auxiliary wheel 23 and the first drive roller 21 adjustable, so that the sleeve conveying mechanism 2 can quickly adapt to sleeves of different diameters. After the axial distance between the first auxiliary wheel 23 and the first drive roller 21 is adjusted, the first locking member 24 can be tightened again. This structural design is not only easy to operate, but also significantly improves the adaptability of the bushing conveying mechanism 2 to bushings of different specifications through the precise coordination of mechanical components, providing a strong guarantee for the efficient and stable operation of the transformer automatic winding machine 100.

[0039] In some embodiments, the first locking member 24 can be kept in a state where the first slide 22 is properly locked but the sliding of the first slide 22 relative to the first slide groove 111 is not restricted, thus preserving the freedom of the first slide 22 in the extension direction. Furthermore, a first elastic member is provided between the first locking member 24 (or the first slide 22) and the seat plate 11, such that the first elastic member can force the first slide 22 to drive the first auxiliary wheel 23 to move constantly towards the first drive roller 21. This enables the sleeve conveying mechanism 2 to adapt to changes in sleeve size and ensures that the first auxiliary wheel 23 and the first drive roller 21 maintain appropriate clamping of the sleeve, thereby ensuring that the first auxiliary wheel 23, in conjunction with the first drive roller 21, reliably drives the sleeve movement. Depending on the function and location of the first elastic member, it can be a compression spring or a tension spring. The design ensures that the sleeve conveying mechanism 2 can automatically adjust according to the change of sleeve diameter under the synergistic action of the first locking member 24 and the first elastic member, and ensures that the first auxiliary wheel 23 and the first drive roller 21 are in real time close to the sleeve, without the need for frequent manual adjustment, thus achieving dynamic self-adaptation and ensuring that the sleeve always maintains the best conveying state.

[0040] The first drive unit 25 is mounted on the frame 1. The first drive unit 25 is used to drive the first drive roller 21 to rotate, thereby controlling the movement of the sleeve. Preferably, the first drive unit 25 is a stepper motor or a servo motor to precisely control the movement distance of the sleeve.

[0041] The guide sleeve 26 is preferably parallel to the height direction. The guide sleeve 26 is mounted on the frame 1, and the sleeve can pass through the guide sleeve 26 to guide the sleeve and ensure reliable movement of the sleeve. One guide sleeve 26 is matched with one first drive roller 21 and one first auxiliary wheel 23. Thus, the number of guide sleeves 26, first drive rollers 21, and first auxiliary wheels 23 is equal, and can be set to two or more according to the processing requirements of the transformer automatic winding machine 100. The extension of the guide sleeve 26 passes through the first clamping position. The guide sleeve 26 is disconnected at the first drive roller 21 and the first auxiliary wheel 23 to expose the sleeve passing through it, thereby allowing the first drive roller 21 and the first auxiliary wheel 23 to cooperate in driving the sleeve to move.

[0042] The wire conveying mechanism 3 includes a second drive roller 31, a second carriage 32, a second auxiliary wheel 33, a second locking member 34, a second drive unit 35, and a wire sleeve 36. The second drive roller 31 is rotatably mounted on the frame 1 about its own axis. The second drive roller 31 is parallel to the first drive roller 21, and the second drive roller 31 is preferably distributed along the axial direction of the first drive roller 21.

[0043] The second auxiliary wheel 33 is rotatably mounted on the second carriage 32 around its own axis. A second clamping position is formed between the second auxiliary wheel 33 and the second drive roller 31. The second clamping position is used to allow the wire to pass through and to properly clamp the wire so that the wire is driven to move towards the sleeve under the cooperation of the second drive roller 31 and the second auxiliary wheel 33.

[0044] The seat plate 11 is also provided with a second sliding groove 112, which is parallel to the first sliding groove 111 and passes through the seat plate 11. The second slide 32 is slidably connected to the second sliding groove 112. In addition, the seat plate 11 also has a second strip groove 114, which is located at the bottom of the second sliding groove 112 and parallel to the second sliding groove 112, and passes through the seat plate 11 in the height direction.

[0045] The second locking member 34 passes through the second slot 114 from the bottom of the seat plate 11 and connects to the second slide 32. The second locking member 34 can lock the second slide 32 and the seat plate 11 to prevent the second slide 32 from sliding relative to the seat plate 11, thereby preventing the second auxiliary wheel 33 from moving relative to the first drive roller 21 and ensuring the reliability of the second drive roller 31 and the second auxiliary wheel 33 in conveying the wire. When it is necessary to adjust the relative position of the second auxiliary wheel 33 and the second drive roller 31, the second locking member 34 can be loosened appropriately so that it contacts the mutual fixation of the second slide 32 and the seat plate 11, thereby making the axial distance between the second auxiliary wheel 33 and the second drive roller 31 adjustable, so that the wire conveying mechanism 3 can quickly adapt to wires of different diameters. After the axial distance between the second auxiliary wheel 33 and the second drive roller 31 is adjusted, the second locking member 34 can be tightened again. Similarly, this structural design makes the adjustment of the center distance between the second auxiliary wheel 33 and the second drive roller 31 easier, enabling the wire conveying mechanism 3 to quickly adapt to new sizes and specifications of wires, significantly improving the adaptability of the wire conveying mechanism 3 to wires of different specifications, and providing a strong guarantee for the efficient and stable operation of the transformer automatic winding machine 100.

[0046] In some embodiments, the second locking member 34 can also be kept in a state where the second slide 32 is properly locked but the sliding of the second slide 32 relative to the second slide groove 112 is not restricted, thus preserving the freedom of the second slide 32 in the extension direction. Furthermore, a second elastic member is provided between the second locking member 34 (or the second slide 32) and the seat plate 11, allowing the second elastic member to force the second slide 32 to drive the second auxiliary wheel 33 to move towards the second drive roller 31. This enables the wire conveying mechanism 3 to adapt to changes in wire size and ensures that the second auxiliary wheel 33 and the second drive roller 31 maintain appropriate clamping of the wire, ensuring reliable wire movement by the second auxiliary wheel 33 in conjunction with the second drive roller 31. Depending on the function and location of the second elastic member, it can be a compression spring or a tension spring. This design, through the synergistic action of the second locking member 34 and the second elastic member, ensures that the wire conveying mechanism 3 can automatically adjust according to changes in wire diameter, ensuring that the second auxiliary wheel 33 and the second drive roller 31 are in real-time contact with the wire, eliminating the need for frequent manual adjustments, achieving dynamic adaptation, and ensuring that the wire is always in optimal conveying condition.

[0047] The second drive unit 35 is mounted on the frame 1 and is used to drive the second drive roller 31 to rotate, thereby controlling the movement of the wire. Preferably, the first drive unit 25 is a stepper motor or a servo motor to precisely control the movement distance of the wire.

[0048] The conductor sleeve 36 is preferably parallel to the height direction. The conductor sleeve 36 is mounted on the frame 1, and the conductor can pass through it to guide the conductor and ensure reliable movement. One conductor sleeve 36 is matched with one second drive roller 31 and one second auxiliary wheel 33. Therefore, the number of conductor sleeves 36, second drive rollers 31, and second auxiliary wheels 33 is equal, and can be set to two or more depending on the processing requirements of the automatic transformer winding machine 100. The extension of the conductor sleeve 36 passes through the second clamping position. The conductor sleeve 36 breaks at the second drive roller 31 and the second auxiliary wheel 33 to expose the conductor passing through it, thereby allowing the second drive roller 31 and the second auxiliary wheel 33 to cooperate in driving the conductor's movement.

[0049] Combination Figure 5 The tube cutting mechanism 4 includes a sliding seat 41, a clamping assembly 42, a cutter 43, a third drive unit 44, a fourth drive unit 45, a fifth drive unit 46, and a tube connecting unit 47. The frame 1 is provided with a track parallel to the axial direction of the first drive roller 21. The sliding seat 41 is slidably connected to the track. The fourth drive unit 45, the fifth drive unit 46, and the tube connecting unit 47 are all mounted on the sliding seat 41.

[0050] The clamping assembly 42 includes two clamping blocks 421, which are arranged in a mirror image. Each clamping block 421 is provided with a V-groove 4211, which is parallel to the conduit sleeve 26 and passes through the clamping block 421. A clamping position can be formed between the corresponding V-grooves 4211 on the two clamping blocks 421 for clamping the sleeve.

[0051] The third drive mechanism preferably includes a ball screw and a motor. The motor drives the ball screw to rotate, and the ball screw is parallel to the first drive shaft. The sliding seat 41 is connected to the nut of the ball screw, so that the third drive mechanism can drive the sliding seat 41 to move axially in the first drive roller 21, so that the clamping assembly 42 can be moved below the conduit sleeve 26 / wire sleeve 36 to clamp the sleeve / pass the wire through the sleeve on the clamping assembly 42. Preferably, the motor is a stepper motor or a servo motor to work with the ball screw to precisely control the movement distance of the sliding seat 41, ensuring that the clamping assembly 42 mates with the conduit sleeve 26 / wire sleeve 36.

[0052] The fourth drive unit 45 is used to drive the two clamping blocks 421 to move closer or separate. Preferably, the sliding seat 41 includes a body 411 and a first connecting seat 412, with the first connecting seat 412 mounted on the body 411. The first of the two clamping blocks 421 is fixedly mounted on the first connecting seat 412, and the fourth drive unit 45 drives the second clamping block 421 to move, causing the two clamping blocks 421 to move closer or separate. By fixing the first of the two clamping blocks 421 to the first connecting seat 412, clamping or separation is achieved solely by driving the second clamping block 421 to move via the fourth drive unit 45, effectively simplifying the structural design of the fourth drive unit 45. Compared to the dual-drive mode, this solution reduces the number of drive components and linkage structures, lowering manufacturing and maintenance costs. Meanwhile, since the first clamping block 421 is fixed in position, the second clamping block 421 moves with it as a reference during the adjustment process. This allows the center line of the clamping position formed by the V-groove 4211 of the two clamping blocks 421 to more accurately coincide with the center line of the bushing, significantly improving the accuracy of bushing positioning and providing a stable and reliable foundation for subsequent cutting processes. In addition, the single drive mode greatly simplifies the control logic of the fourth drive unit 45, eliminating the need for complex synchronous control algorithms. Operators can more conveniently adjust the spacing of the clamping blocks 421, effectively improving the operating efficiency and user experience of the tube cutting mechanism 4, and further enhancing the overall performance of the transformer automatic winding machine 100.

[0053] Furthermore, the first connecting seat 412 has a guide rail 4121, which is parallel to the vertical line between the axis of the first auxiliary wheel 23 and the first drive roller 21. A third slide 4122 is mounted on the guide rail 4121, and a second clamping block 421 is mounted on the third slide 4122. A fourth drive unit 45 is connected to the third slide 4122, so that the fourth drive unit 45 can drive the second clamping block 421 to move relative to the first clamping block 421 through the third slide 4122. A third elastic element 4123 is provided between the third slide 4122 and the sliding seat 41, and the third elastic element 4123 forces the third slide 4122 to move toward the fourth drive unit 45; wherein, the fourth drive unit 45 is preferably a cylinder. This optimized structural design significantly improves the ease of control of the tube-cutting mechanism 4 through the synergistic effect of the third elastic element 4123 and the fourth drive unit 45. In this design, the fourth drive unit 45 only needs to drive the third slide 4122 in one direction to move the second clamping block 421 towards the first clamping block 421 to complete the clamping action of the sleeve. When the clamping task is completed, the third elastic element 4123 releases its elastic force, automatically pushing the third slide 4122 to reset, and driving the second clamping block 421 back to its initial position. This process eliminates the need for complex bidirectional drive control, greatly simplifying the control program of the fourth drive unit 45, reducing costs, and also reducing the steps of writing and executing control instructions, thus lowering the requirements and testing difficulty of the control system.

[0054] Furthermore, the body 411 is provided with a third strip groove parallel to the vertical line (i.e., parallel to the first slide groove 111), which passes through the body 411 axially along the first drive roller 21. The sliding seat 41 also includes a third locking member, which passes through the third strip groove and connects to the first connecting seat 412. By releasing the third locking member, the first connecting seat 412 can flexibly adjust its position along the vertical line within the constraint range of the third strip groove, thereby driving the guide rail 4121, the third slide 4122, and the second clamping block 421 mounted thereon to make precise displacements. During the adjustment process, the operator can use the first clamping block 421 as a reference and, based on the actual position of the sleeve, precisely adjust the second clamping block 421 to a suitable position so that the clamping center line formed by the V-shaped grooves of the two clamping blocks 421 is fully aligned with the center line of the sleeve. After adjustment, tighten the third locking component to secure the first connecting seat 412, preventing it from shifting during equipment operation and ensuring that the precise alignment between the clamping center line and the sleeve center line is maintained.

[0055] The fifth drive unit 46 is mounted on the first connecting seat 412. The cutter 43 is connected to the drive end of the fifth drive unit 46, so that the fifth drive unit 46 can drive the cutter 43 to move relative to the clamping assembly, thereby controlling the cutter 43 to cut the sleeve to a fixed length. The cutter 43 is located above the clamping assembly, and preferably, the cutter 43 is flat against the top of the clamping assembly 42. In addition, the fifth drive unit 46 is preferably a cylinder.

[0056] The control unit 47 includes a drive module 471, a second connecting seat 472, a rocker arm 473, and a detection sensor 474. The drive module 471 is mounted on the first connecting seat 412, and preferably a cylinder. The second connecting seat 472 is mounted on the drive end of the drive module 471, and the rocker arm 473 is rotatably mounted on the second connecting seat 472, so that the drive module 471 can drive the second connecting seat 472 to move the rocker arm 473 relative to the clamping assembly 42; preferably, the second connecting seat 472 moves in a direction parallel to the first strip groove 113.

[0057] The rotation axis of the rocker 473 is parallel to the axial direction of the first drive roller 21, and the rocker 473 is located below the clamping assembly 42; wherein, the first end of the rocker 473 is provided with a counterweight 4731, such that under the action of the counterweight 4731, the second end of the rocker 473 is at the same height as the first end, or the second end of the rocker 473 is higher than the first end.

[0058] The detection sensor 474 is mounted on the second connecting seat 472, with its detection end facing the counterweight 4731. When the drive module 471 drives the second connecting seat 472 to move the rocker arm 473 along the vertical line parallel to the axis between the first auxiliary wheel 23 and the first drive roller 21 to below the clamping assembly 42, when the sleeve on the clamping assembly 42 falls, the sleeve can press on the second end of the rocker arm 473, causing the first end of the rocker arm 473 to tilt up. The detection sensor 474 is used to detect whether the first end of the rocker arm 473 is tilted up, so that the control system of the auxiliary transformer automatic winding machine 100 can control the third drive unit 44 to drive the sliding seat 41 to move. Preferably, the detection sensor 474 can be a proximity switch or a micro switch.

[0059] The connecting unit 47 can be used to receive the first section of the sleeve that has been cut off, preventing the first section of the sleeve from falling down. It can also limit the first section of the sleeve so that the two sections of the sleeve can maintain a set distance. The design of the upper tilting plate 473 of the connecting unit 47 allows it to control the opening and closing of the two clamping blocks 421 through the detection sensor 474 after receiving the falling first section of the sleeve, so as to clamp and cut the other section of the sleeve. It also helps to determine whether both sections of the sleeve have been removed by the pipe cutting mechanism 4.

In addition, the sixth drive unit 511 can also drive the first operating end 512 to rotate about an axis parallel to the axial direction of the first drive roller 21.

Specifically, the seventh drive unit 521 can drive the second operating end 522 to move in the height direction, (parallel to) the axial direction of the first drive roller 21, and (parallel to) the extension direction of the first strip groove 113, thereby realizing the three-dimensional spatial movement of the second operating end 522.

The wire cutting unit 523 is installed at the second operating end 522. The wire cutting unit 523 is used to cut the wire to trim the two ends of the wire wrapped around the transformer frame.

[0062] Combination Figure 8 The winding mechanism 6 includes an eighth drive unit 61 and a winding end 62. The eighth drive unit 61 is mounted on the frame 1. The eighth drive unit 61 is used to drive the winding end 62 to move between the winding station, the loading station and the unloading station of the transformer automatic winding machine 100. That is, the eighth drive unit 61 can drive the winding end 62 to move in the height direction, the axial direction (parallel to) the first drive roller 21 and the extension direction (parallel to) the first strip groove 113, so as to realize the three-dimensional spatial movement of the winding end 62. In addition, the eighth drive unit 61 can also drive the winding end 62 to rotate about an axis parallel to the extension direction of the first strip groove 113, so as to realize the winding of the wire onto the frame of the transformer.

[0063] The adhesive application mechanism 7 is mounted on the frame 1. The eighth drive unit 61 is also used to drive the winding end 62 to move to the adhesive application mechanism 7.

The feeding mechanism 81 can be a conveyor belt mechanism or a linear vibrator mechanism to realize the automated feeding of the winding mechanism 6. A feeding mechanism 82 is provided at the unloading station. The feeding mechanism 82 can be a linear vibrator mechanism to realize the transfer of the processed transformer to the next designated position, or the unloading structure is a feeding trough, so that after the processing of the transformer is completed, the transformer is transferred to the feeding trough through the winding end 62 of the winding mechanism 6 to realize the unloading of the transformer, so that the transformer can be moved to the next designated position through the feeding trough.

[0065] The working principle of the automatic transformer winding machine 100 is briefly described below:

[0066] When the tubing is being transported, the tubing cutting mechanism 4 controls the clamping assembly 42 to move to the position below the corresponding tubing sleeve 26. Then, the tubing transport mechanism drives the unwound tubing to move a fixed distance to the clamping assembly 42. Next, the fourth drive unit 45 drives the two clamping blocks 421 of the clamping assembly 42 to clamp the tubing. Then, the fifth drive unit 46 drives the cutter 43 to cut the tubing, forming the first section of tubing.

[0067] Next, the fifth drive unit 46 drives the cutter 43 to reset, and the fourth drive unit 45 drives the two clamping blocks 421 of the clamping assembly 42 to release the clamping of the first section of the sleeve, causing the first section of the sleeve to fall to the second end of the rocker arm 473; the first end of the rocker arm 473 is lifted, the detection sensor 474 detects that the second end of the rocker arm 473 is approaching, and sends a signal to the control system. Then, the conduit delivery mechanism drives the unwound sleeve to move again, so that the sleeve moves a fixed distance to the clamping assembly 42; then, the fourth drive unit 45 drives the two clamping blocks 421 of the clamping assembly 42 to clamp the unwound sleeve and the first section of the sleeve again, and then the fifth drive unit 46 drives the cutter 43 to cut the sleeve to form the second section of the sleeve.

[0068] Next, the fifth drive unit 46 drives the cutter 43 to reset, the connecting pipe unit 47 to reset, and then the third drive unit 44 drives the sliding seat 41 to move, so that the first and second sleeve sections move below the corresponding wire sleeves 36. At the same time, the first operating arm mechanism 51 drives the first operating end 512 to move below the first sleeve section, and the second operating arm drives the second operating end 522 to move below the first operating end 512.

[0069] Next, the wire conveying mechanism 3 drives the wire to pass through the second sleeve, the first sleeve, the corresponding component on the first operating end 512, and the corresponding component on the second operating end 522 in sequence.

[0070] Next, the eighth drive unit 61 drives the winding end 62 to grab the transformer frame to the winding station, and then the sixth drive unit 511 drives the first operating end 512 to move to the winding station, and the seventh drive unit 521 drives the second operating end 522 to move to the winding station.

[0071] Next, the seventh drive unit 521 drives the second operating end 522 to wind the combination of the first bushing and the first end of the conductor onto the first end foot of the transformer frame. Subsequently, the eighth drive unit 61 drives the winding end 62 to cooperate with the first operating end 512 to wind the conductor onto the transformer frame. During this process, as a first option, the clamping assembly 42 can maintain the clamping of the second bushing, while as a second option, the clamping assembly 42 can release the clamping of the second bushing, allowing the cutting mechanism 4 to cooperate with the bushing conveying mechanism 2 to cut the bushing in the next cycle. Finally, the sixth drive unit 511 drives the first operating end 512 to wind the combination of the second bushing and the second end of the conductor onto the second end foot of the transformer frame. Subsequently, the seventh drive unit 521 drives the second operating end 522 to move so that the wire cutting unit 523 cuts the conductor to form the second end of the conductor wound on the transformer frame.

[0072] Next, the first operating arm mechanism 51 and the second operating arm mechanism 52 reset and await the next cycle of winding processing; the eighth drive unit 61 drives the winding end 62 to move to the adhesive application mechanism 7 for adhesive application, then drives the winding end 62 to move to the unloading mechanism 82 for unloading, and then resets to await the next cycle of winding processing. Since the hanging, winding, and adhesive application processes are all existing technologies, they will not be described in detail here.

[0073] In summary, the bushing conveying mechanism 2 of the automatic transformer winding machine 100 provided by this utility model can accurately adapt to bushings of different diameters by adjusting the axial distance between the first auxiliary wheel 23 and the first drive roller 21; similarly, the conductor conveying mechanism 3 can achieve adaptive conveying of conductors of different diameters by adjusting the axial distance between the second auxiliary wheel 33 and the second drive roller 31. In the tube cutting mechanism 4, the two clamping blocks 421, under the action of the fourth drive unit 45, cooperate with the V-groove on them to adjust the clamping degree according to the bushing size, and cooperate with the third drive unit 44 to drive the sliding seat 41 to move, so as to achieve precise cutting of bushings of different specifications. The above design, by flexibly adjusting the positions of the first auxiliary wheel 23 and the second auxiliary wheel 33 and the spacing of the clamping blocks 421, eliminates the need to equip the automatic transformer winding machine 100 with multiple sets of special matching components, significantly reducing the manufacturing, use and maintenance costs of the equipment. At the same time, it avoids the process of replacing components, greatly shortens the adjustment time of the bushing conveying mechanism 2, the conductor conveying mechanism 3 and the tube cutting mechanism 4, and enables the transformer automatic winding machine 100 to quickly adapt to changes in conductor and bushing size specifications, greatly improving the versatility and practicality of the equipment.

[0074] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
