Description

Technical Field

[0001] This utility model relates to the field of electromagnetic component manufacturing technology, specifically to a fully automatic wire pulling and corner cutting mechanism for winding electromagnetic components. Background Technology

[0002] Electromagnetic components (such as inductors, transformers, coils, etc.) are core components in the fields of magnetic cores, coils, and magnets. The winding and lead (i.e., enameled wire lead-out ends) cutting (corner cutting) processes in their manufacturing are key links that affect the electrical performance and assembly accuracy of the product. After the winding process is completed, the lead-out ends of the enameled wire need to be cut to a fixed length according to the specified length. The consistency of the cut length and the flatness of the cut directly affect the lead coplanarity, welding reliability, and overall electrical parameters of the electromagnetic component.

[0003] The existing enameled wire cutting process has the following technical shortcomings:

[0004] Most existing corner-cutting devices use independent workstations, and processes such as winding, flattening, and cutting require manual connection. For electromagnetic components with multiple leads, all leads need to be cut (corner-cut) sequentially. Existing devices lack a mechanism that can automatically index and position multiple enameled wires one by one and perform continuous corner-cutting operations, resulting in low cutting efficiency and poor length consistency for multi-wire electromagnetic components.

[0005] Existing corner-cutting devices use cylinders to drive pressure blocks to press down or release multiple wires in the tensioner. However, the force is difficult to control. If it is too loose, the wires will sag; if it is too tight, they will break. Furthermore, since they are not integrated into the corner-cutting mechanism, it is difficult to apply independent and constant tension to a single enameled wire to be cut during the instantaneous corner-cutting process.

[0006] In existing cutting equipment, when changing electromagnetic components of different specifications, the replacement of positioning fixtures and position calibration are cumbersome, making it difficult to meet the production needs of multiple varieties and small batches of electromagnetic components. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a fully automatic wire pulling and corner cutting mechanism for winding electromagnetic components. This solves the problems of existing devices, which mostly use independent workstations, requiring manual coordination of winding, flattening, and lead cutting processes. For electromagnetic components with multiple leads, all leads must be cut sequentially (corner cutting). Existing devices lack a mechanism for automatically indexing and positioning multiple enameled wires and performing continuous corner cutting, resulting in low efficiency and poor length consistency for multi-lead electromagnetic components. Existing corner cutting devices use cylinders to drive pressure blocks to press down or release multiple wires in the tensioner, but the force is difficult to control; too loose and the wires may sag, too tight and they may break. Furthermore, these devices are not integrated into the corner cutting mechanism, making it difficult to apply independent and constant tension to a single enameled wire during the instantaneous corner cutting process. In existing corner cutting equipment, changing positioning fixtures and calibrating positions when replacing electromagnetic components of different specifications is cumbersome, making it difficult to meet the technical needs of producing multiple varieties of small batches of electromagnetic components.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0012] The lifting platform is slidably connected to a guide frame that is fixedly installed on the bottom wall of the workbench. An adjustable guide block is slidably connected to the guide frame along the pulling direction of the pulling wire assembly. A distance sensor is fixedly installed on the wall surface of the electromagnetic element clamp near the adjustable guide block.

The two limiting rods are symmetrically distributed along the electromagnetic element positioning rod. The guide positioning seat has limiting holes that are compatible with the electromagnetic element positioning rod and the limiting rods. The guide positioning seat is threadedly connected to the side wall of the positioning platform.

[0016] Preferably, the tensioning assembly includes a pressure sensor fixed to the upper wall of the electromagnetic element chuck, a buffer spring fixedly installed between the pressure sensor and the bottom wall of the drive cylinder, a damping ring fixedly connected to the connection end of the drive cylinder and the electromagnetic element chuck, an energized slip ring fixedly installed at the upper wall connection end of the electromagnetic element chuck, and a clearance groove provided at the drive end of the drive cylinder to slide and adapt to the energized slip ring.

[0020] This utility model provides a fully automatic wire pulling and corner cutting mechanism for winding electromagnetic components, which has the following advantages:

[0021] This invention achieves automatic, individual indexing and continuous corner cutting of all enameled wire leads of electromagnetic components by using a drive motor in the angle adjustment assembly to drive the guide positioning seat on the positioning table to rotate and index. This solves the problem that existing technologies require manual alignment or separate processing of multi-wire electromagnetic components at independent workstations, and significantly improves the corner cutting efficiency of electromagnetic components.

[0022] This invention utilizes the coordinated control of a pressure sensor, a buffer spring, and a drive cylinder in the tensioning assembly to apply and maintain a preset constant tension on a single enameled wire to be cut before the corner is cut. This ensures that the enameled wire is cut while under tension, effectively preventing damage to the insulation layer of the enameled wire, and also ensures the high consistency of the cut corner length of each enameled wire.

[0023] This invention utilizes a quick-detachable connection structure between an adjustable guide block and a guide positioning seat that slides along the guide frame. This enables stepless adjustment of the chamfer length and rapid replacement of positioning fixtures for electromagnetic components of different specifications, thereby improving the equipment's adaptability to different electromagnetic component product specifications and meeting the production needs of multiple varieties and small batches.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Please see Figures 1-6An automatic wire pulling and corner cutting mechanism for winding electromagnetic components includes a worktable 1. An electromagnetic component positioning assembly, a recycling box 2, and a wire pulling assembly are sequentially fixedly installed on the bottom wall of the worktable 1 along its length. A corner cutting control box 9 is slidably connected to the top wall of the worktable 1 along its length. The sliding connection between the corner cutting control box 9 and the worktable 1 is achieved using a screw drive mechanism. A horizontal drive motor is fixedly installed on the top wall of the worktable 1. A horizontal screw is fixedly connected to the drive end of the horizontal drive motor. The horizontal screw is rotatably connected to the top wall of the worktable 1. The corner cutting control box 9 is meshed with the horizontal screw. When the horizontal drive motor rotates in both directions, it drives the corner cutting control box 9 to slide back and forth along the length of the worktable 1 via the horizontal screw.

[0033] The electromagnetic component positioning assembly includes a lifting platform 3 and a positioning platform 5. The telescopic end of the lifting platform 3 is equipped with an angle adjustment component. A limit rod 4 is fixedly installed on the lower wall of the positioning platform 5. The limit rod 4 is rotatably connected to the top connection end of the angle adjustment component, so that the angle adjustment component can drive the positioning platform 5 to rotate around the axis of the limit rod 4, thereby achieving the indexing and alignment of each enameled wire on the electromagnetic component. An electromagnetic component positioning rod 6 is fixedly installed at the center of the positioning platform 5, which is used to insert into the center hole of the electromagnetic component to achieve radial positioning. A guide positioning seat 7 is detachably connected to the positioning platform 5. Several symmetrically distributed wire positioning grooves 8 are opened on the two side walls of the guide positioning seat 7 to accommodate and constrain the lead-out direction of each enameled wire.

[0034] A drive cylinder 10 is fixedly installed on the lower wall of the corner cutting control box 9. The drive end of the drive cylinder 10 rotates and is slidably connected to an electromagnetic element chuck 11 and a tensioning assembly. The electromagnetic element chuck 11 is used to clamp and release the electromagnetic element, and the tensioning assembly is used to apply and maintain a constant tension on the enameled wire during the wire pulling process. A corner cutting blade 12 is detachably connected to the lower wall of the corner cutting control box 9. A corner cutting driver is fixedly installed on the lower wall of the corner cutting control box 9. The corner cutting blade 12 is fixedly connected to the drive end of the corner cutting driver. The corner cutting driver drives the corner cutting blade 12 to descend and close to complete the corner cutting, and then lifts it up to reset. This is used to cut the enameled wire after it reaches the predetermined tension.

[0035] The lifting platform 3 is slidably connected to a guide frame 13 fixedly installed on the bottom wall of the workbench 1. The lifting platform 3 can be vertically raised and lowered along the guide frame 13, driving the positioning platform 5 and its electromagnetic components to rise and fall synchronously, so that the enameled wire enters or leaves the adjustable guide block 14. The extension and retraction of the lifting platform 3 is driven by a built-in cylinder. The adjustable guide block 14 is slidably connected to the guide frame 13 along the wire pulling direction of the wire pulling assembly. The position of the adjustable guide block 14 can be adjusted along the wire pulling direction and fixed by a locking screw, which is used to determine the chamfer length. A distance sensor 15 is fixedly installed on the wall of the electromagnetic component chuck 11 near the adjustable guide block 14, which is used to detect the distance between the pneumatic chuck 30 and the adjustable guide block 14. When the preset clamping distance is reached, the pneumatic chuck 30 is triggered to close and clamp the enameled wire.

[0036] The wire pulling assembly includes a carriage 29, in which a pneumatic chuck 30 is slidably connected. The pneumatic chuck 30 is pneumatically driven and its opening and closing are controlled by compressed air. The pneumatic chuck 30 is used to clamp the end of the enameled wire and completes the wire pulling and pre-tensioning actions under the drive of the lead screw 31. The recycling box 2 is located directly below the adjustable guide block 14 and the pneumatic chuck 30, so that the enameled wire end cut by the corner cutter 12 automatically falls into the recycling box 2 under the action of gravity.

[0037] The angle adjustment assembly includes a transmission groove 16 opened at the telescopic end of the lifting platform 3. A drive motor 17 is fixedly installed on the bottom wall of the transmission groove 16. A drive bevel gear 18 is fixedly installed on the drive end of the drive motor 17. A driven bevel gear 19 that meshes with the drive bevel gear 18 is fixedly installed on the lower wall connecting end of the limiting rotating rod 4. The drive motor 17 drives the limiting rotating rod 4 and the positioning platform 5 to rotate through the meshing of the drive bevel gear 18 and the driven bevel gear 19, thereby realizing the successive indexing of each pull-line positioning groove 8 on the guide positioning seat 7.

[0038] Two limiting rods 20 are fixedly installed on the upper wall of the positioning platform 5. The two limiting rods 20 are symmetrically distributed along the electromagnetic element positioning rod 6. The guide positioning seat 7 has limiting holes that are compatible with the electromagnetic element positioning rod 6 and the limiting rods 20. The electromagnetic element positioning rod 6 and the two limiting rods 20 work together to achieve precise positioning of the guide positioning seat 7. The guide positioning seat 7 is threaded to the side wall of the positioning platform 5, which facilitates quick replacement of the appropriate guide positioning seat 7 according to different specifications of electromagnetic elements.

[0039] The tensioning assembly includes a pressure sensor 21 fixed to the upper wall of the electromagnetic component chuck 11, and a buffer spring 22 fixedly installed between the pressure sensor 21 and the bottom wall of the drive cylinder 10. When the drive cylinder 10 extends and drives the electromagnetic component chuck 11 to descend, and the enameled wire is tightened, the buffer spring 22 is compressed. The pressure sensor 21 detects the spring force value in real time. When the preset tension threshold is reached, the drive cylinder 10 stops extending, thereby achieving constant tension control of the enameled wire. A damping ring 23 is fixedly connected to the connection end of the drive cylinder 10 and the electromagnetic component chuck 11 to provide rotational damping and prevent the electromagnetic component chuck 11 from rotating freely in the non-drive state. An energized slip ring 24 is fixedly installed on the upper wall connection end of the electromagnetic component chuck 11. The drive end of the drive cylinder 10 has a clearance groove 25 that slides and adapts to the energized slip ring 24. The electromagnetic component chuck 11 is connected to the energized slip ring 24 to achieve simultaneous sliding and rotation of the electromagnetic component chuck 11 within the clearance groove 25 when energized.

[0040] A wire pressing plate 26 is fixedly installed on the lower wall of the electromagnetic component chuck 11. The wire pressing plate 26 has a wire pulling groove 27. The guide positioning seat 7 has a wire pressing clearance groove 28 that is compatible with the wire pressing plate 26. When the electromagnetic component chuck 11 descends, the wire pressing plate 26 is inserted into the wire pressing clearance groove 28, pressing the enameled wire tightly in the wire pulling positioning groove 8 to prevent the enameled wire from coming out during indexing rotation and wire pulling. Both the wire pulling positioning groove 8 and the wire pulling groove 27 are V-shaped grooves, which use the automatic centering characteristics of the V-shaped grooves to guide the enameled wire to be accurately positioned.

[0041] A lead screw 31 is rotatably connected inside the slide 29. The pneumatic chuck 30 is meshed with the lead screw 31. The rotation of the lead screw 31 drives the pneumatic chuck 30 to reciprocate along the slide 29, thereby moving towards the adjustable guide block 14 to clamp the enameled wire and completing the pre-tensioning and reset actions after clamping.

[0042] During wire pulling, the adjustable guide block 14 is coaxially aligned with the pneumatic chuck 30 and the corresponding wire pulling positioning groove 8 to ensure that the enameled wire travels from the wire pulling positioning groove 8 through the adjustable guide block 14 to the pneumatic chuck 30 in a straight line, thus ensuring the accuracy of wire pulling and corner cutting.

[0043] Specifically:

[0044] Before operation, the operator slides the adjustable guide block 14 along the guide frame 13 to the target position according to the required chamfer length of the electromagnetic component to be processed, and then fixes it with locking screws. A suitable guide positioning seat 7 is selected according to the specifications of the electromagnetic component, its limiting hole is aligned with the electromagnetic component positioning rod 6 and the two limiting rods 20, and then inserted and tightened with side wall fixing screws. In the control system, process parameters such as the enameled wire tension threshold, the clamping trigger distance of the distance sensor 15, and the chamfering delay of the chamfering blade 12 are set. After starting the equipment, each actuator automatically resets to its initial position.

[0045] At the start of the operation, the corner-cutting control box 9 slides along the length of the top wall of the workbench 1 to the loading station. The drive cylinder 10 drives the electromagnetic component chuck 11 to descend, clamp the wound electromagnetic component, and then retracts to reset. The corner-cutting control box 9 slides to directly above the electromagnetic component positioning rod 6. The drive cylinder 10 drives the electromagnetic component chuck 11 and the electromagnetic component it holds to descend slowly. The center hole of the electromagnetic component is aligned with the electromagnetic component positioning rod 6 and inserted. The lead ends of each enameled wire fall into the corresponding pull-wire positioning grooves 8 on the guide positioning seat 7. The drive cylinder 10 continues to descend until the wire pressing plate 26 is inserted into the wire pressing clearance groove 28 of the guide positioning seat 7. The enameled wire is guided into the pull-wire positioning groove 8 by the pull-wire pressing groove 27 on the wire pressing plate 26 and pressed and fixed. The drive cylinder 10 pauses, the electromagnetic component chuck 11 is released, and the electromagnetic component remains fixed to the electromagnetic component positioning rod 6 under the action of gravity. At this time, there is a gap between the pressure plate 26 and the bottom of the pressure groove 28, which is reserved for subsequent tensioning and compression.

[0046] Then, the drive motor 17 starts, driving the driven bevel gear 19 and the limit rod 4 to rotate via the drive bevel gear 18, which in turn drives the positioning table 5 and the electromagnetic components on it to rotate. At the same time, the electromagnetic component chuck 11 rotates synchronously through the cooperation of the wire pressing plate 26 and the wire pressing clearance groove 28. When the wire positioning groove 8 corresponding to the outermost enameled wire to be cut is coaxially aligned with the adjustable guide block 14, the drive motor 17 stops rotating, and the lifting platform 3 descends vertically along the guide frame 13, driving the positioning table 5 and the electromagnetic components to descend synchronously (at the same time, the electromagnetic component chuck 11 follows the descent), so that the enameled wire to be cut falls into the V-shaped groove at the top of the adjustable guide block 14.

[0047] The screw 31 rotates forward, driving the pneumatic chuck 30 to move along the slide 29 towards the adjustable guide block 14. When the distance sensor 15 detects that the distance between the pneumatic chuck 30 and the adjustable guide block 14 reaches the preset clamping distance, the screw 31 stops rotating, and the pneumatic chuck 30 closes to firmly clamp the end of the enameled wire. The screw 31 rotates slightly in the reverse direction, driving the pneumatic chuck 30 to move backward by 1 to 2 mm to complete the pre-tensioning and straighten the enameled wire. The drive cylinder 10 extends, driving the electromagnetic component chuck 11 and the wire pressing plate 26 to continue descending. The wire pressing plate 26 continues to move towards the bottom of the wire pressing groove 28 to tighten the enameled wire. At this time, the buffer spring 22 begins to be compressed, the pressure sensor 21 detects the initial pressure value, the drive cylinder 10 pauses, and after the value stabilizes, the control system sets the current value of the pressure sensor 21 to zero. After being set to zero, the drive cylinder 10 continues to extend, the buffer spring 22 is further compressed, and the pressure sensor 21 detects the spring force value in real time. When the spring force reaches the preset tension threshold, the drive cylinder 10 stops extending, and the enameled wire is in a constant tension state.

[0048] The corner-cutting blade 12 descends and closes, cutting the enameled wire between the adjustable guide block 14 and the pneumatic chuck 30. The pneumatic chuck 30 releases, and the lead screw 31 rotates in the opposite direction, causing the pneumatic chuck 30 to reset. The cut wire ends fall naturally into the recycling bin 2 directly below under gravity. The corner-cutting blade 12 rises and resets, and the drive cylinder 10 rises until the pressure sensor 21 returns to zero, then rises at the same speed as the lifting platform 3, maintaining the pressure of the pressure sensor 21 until the enameled wire no longer interferes with the adjustable guide block 14 when rotating the electromagnetic element. Then, the drive motor 17 starts again, causing the positioning table 5 to rotate to the position where the next enameled wire to be cut is coaxially aligned with the adjustable guide block 14. The above process of wire insertion, wire tensioning, and corner-cutting reset is repeated until all enameled wires of the electromagnetic element have been cut.

[0049] After all the enameled wires are cut, the drive cylinder 10 retracts, causing the electromagnetic component chuck 11 and the wire pressing plate 26 to rise and disengage from the guide positioning seat 7. The electromagnetic component chuck 11 closes to clamp the processed electromagnetic component. The corner cutting control box 9 slides along the length of the top wall of the worktable 1 to the unloading station. The electromagnetic component chuck 11 releases the finished product to the designated position. Each actuator resets to its initial state, completing a complete work cycle.

[0050] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
