Description

Technical Field

[0001] The present invention relates to a winding method and device, and in particular to an iron core winding method and device for winding a wire around an iron core. Background Art

[0002] In the typical process of winding wire around an iron core, an "I"-shaped iron core is often used. This iron core has a winding core portion and a wire-entry flange portion and a wire-exit flange portion located at each end of the winding core portion. In the winding process of multiple wires, the multiple wires are first pulled through the electrode on the wire-entry flange portion, where they are spot-welded to the starting wire portion. The iron core is then rotated to wind the wires around the winding core portion. The completed wires are then pulled through the electrode on the wire-exit flange portion, where they are spot-welded to the ending wire portion. The wire ends behind the spot welds are then broken to complete the coil product.

[0003] The applicant previously filed Taiwan Patent No. I529759, a patent application titled "Coil Winding Method and Apparatus," which provided a jig located between the two welding seats of the coil, allowing the wire to be wound around the welding seat of the flange portion of the wire outlet end to be turned and abutted against the welding seats on both sides of the jig after winding around the jig, so that the wire could form welding points there. Later, the Bureau approved Taiwan Patent No. I607461, a patent application titled "Multi-wire Winding Method, Multi-wire Winding Apparatus, and Winding-Type Coil Part," which placed a bending jig between multiple electrodes of the flange portion of the wire outlet end, guiding the end portions of the multiple wires from the inside of the flange portion of the other end side to the outside, thereby reducing the risk of short circuits with electrodes of different potentials.

[0004] The background technology of the two aforementioned patent cases is that, although the wire is wound around a jig or a wire bending fixture during the winding process, the wire is bent and folded through the electrode. However, because the jig or the wire bending fixture is located between multiple electrodes, when the wire is wound around the jig or the wire bending fixture, the portion of the wire leaning against the flange of the outlet end will be too close to the electrode on the other side of the jig or the wire bending fixture, causing the high temperature during spot welding of the electrode on the other side to cause the portion of the wire leaning against the flange of the outlet end to be covered. The enameled film insulation layer falls off, causing the conductive layer of the wire to be exposed, which is prone to short circuit during the power-on process. Based on this, the applicant further proposed and was approved by the Taiwan Patent Office with the patent case No. I767383 "Iron Core Winding Method and Device". In this case, a folding fixture is located on the electrode of the flange part of the outlet end. The wire is pulled back from the side of the winding core part outside the electrode of the flange part of the outlet end to make a turn against the folding fixture, thereby preventing the iron core from short circuiting after the wire is wound. Summary of the Invention

[0005] Background Art Patent No. I767383, "Method and Apparatus for Winding Iron Cores," addresses the problem of high temperatures during spot welding of electrodes causing the enamel film insulation coating on the portion of the wire adjacent to the flange of the terminal to peel off, exposing the conductive layer of the wire in that area and making it susceptible to short circuits during power-on. However, because the winding jig is located on the electrode at the flange of the terminal, and the upper surface of the electrode is stained with silver, the silver surface of the electrode under pressure may be damaged. Furthermore, during spot welding, the welding head cannot cover the entire silver surface, so further improvements are still needed.

[0006] Therefore, an object of the present invention is to provide a core winding method that can improve at least one disadvantage of the prior art.

[0007] Another object of the present invention is to provide a core winding device for performing the core winding method.

[0008] Another object of the present invention is to provide a core winding device that can improve at least one disadvantage of the prior art.

[0009] The iron core winding method according to the purpose of the present invention includes: providing a wire rod; providing an iron core, the iron core having a winding core portion and an inlet flange portion and an outlet flange portion, each of which has an electrode provided thereon; when the wire rod is wound around the winding core portion to the outlet flange portion, a folding jig is provided to turn the wire rod and position it on the upper surface of the electrode of the outlet flange portion; wherein the folding jig is displaced to between the inlet flange portion and the outlet flange portion above the iron core with a winding abutment portion, so that an end portion of the front end of the winding abutment portion abuts against the side of the outlet flange portion where the electrode is to be straightened toward the inlet flange portion, and a folding portion abuts against the welding position of the electrode where the wire rod is to be welded to position it, the wire rod is pulled and folded against the folding portion, and displaced beyond the predetermined welding position of the electrode to exit the wire.

[0010] According to another object of the present invention, an iron core winding device includes: a device for performing the iron core winding method as described above, including the winding jig and a winding machine equipped with the winding jig.

[0011] The iron core winding device according to the present invention comprises: a clamp, which is provided at one end of a rotating shaft and can be driven to rotate; a stop member, which is provided at one end of a rotating shaft and can be driven to rotate, and is provided with a stop portion corresponding to the clamping opening of the clamp, and an iron core can be placed between the stop portion and the clamping opening, and the iron core is provided with a winding core portion and an inlet end flange portion and an outlet end flange portion respectively provided with electrodes at both ends of the winding core portion; a folding jig, which is provided There is a winding and abutting portion, and the winding jig can be moved to between the inlet flange and the outlet flange above the iron core, so that one end of the front end of the winding and abutting portion abuts against the side of the electrode facing the inlet flange to form a straight line of the outlet flange, and a folding portion abuts against an end portion of a corresponding wire material to be welded to the welding position of the electrode; thereby, the end portion can be pulled and folded against the folding portion, so that the end portion is displaced beyond the predetermined welding position of the electrode to exit the wire.

[0012] In the iron core winding method and device of the embodiment of the present invention, since the winding jig is not located between multiple electrodes, when the wire is wound through the winding jig, the portion leaning against the flange portion of the outlet end will not be too close to the electrode on the other side of the winding jig, causing the high temperature of the electrode on the other side to cause the enamel film insulation layer covering the outer surface of the portion of the wire leaning against the flange portion of the outlet end to fall off due to the high temperature during spot welding of the electrode on the other side, resulting in the conductive layer of the wire at that location being exposed, which is prone to short circuit during power-on. Moreover, the winding jig is not located on the electrode of the flange portion of the outlet end, so it will not cause damage to the end silver provided on the upper surface of the electrode, and during spot welding, the welding head can cover the entire end silver surface, thereby making the folding of the wire into a straight line and welding operation smoother.

After spot welding, the first wire L1 and the second wire L2 are wound together on the winding core A1 and gradually The wire L1 and the second wire L2 are wound toward the outlet flange A3. When the wire L1 and the second wire L2 reach the outlet flange A3, a first end portion L12 and a second end portion L22 are spot welded to the fourth electrode A33 and the third electrode A32, respectively. The implementation of the features of the present invention is similarly covered by the features of the present invention for a single wire, a plurality of wires twisted or unwound, a plurality of electrodes, or the first end portion L12 is spot welded to the third electrode A32, and the second end portion L22 is spot welded to the fourth electrode A32.

[0108] Please refer to the figure In the first embodiment of the present invention, a folding jig C as shown in the figure is used during winding. The folding jig C can be placed on the table of the winding machine equipment on one side of the X-axis center axis connected by the rotation center of a clamp B1 and a stopper B2, and is also placed between the clamp B1 and the stopper B2. Figure 1When the core A is in the center, the folding jig C is located on one side of the central axis P of the winding core portion A1 of the core A. The folding jig C is driven by a driving mechanism to move in the X, Y, and Z axial directions and can be moved to the top of the core A sandwiched between the clamp B1 and the stop member B2.

[0109] The folding fixture C is in the shape of a plate, which is provided with a fixed portion C1 for linkage with a driving mechanism. The fixed portion C1 is horizontally extended in the X-axis direction, and its front end is bent downward to form an arm C2. The front end of the arm C2 is bent toward the X-axis to form a tapered winding portion C3. The bottom surface C31 of the winding portion C3 is slightly rectangular, and its upper surface C32 is an inclined surface inclined downward from the back to the front. The front end of the winding portion C3 is a rectangular end C33 with a slightly flat surface. One side of the winding portion C3 is formed for the wire L to be folded against. The upright planar folding portion C34; the winding portion C3 is an integral component with the fixed portion C1 and the extension arm C2 and is linked to the fixed portion C1 and the extension arm C2, and can be displaced in the X, Y, and Z axial directions to the folding jig C above the iron core A when the fixed portion C1 is linked to the driving mechanism. In the horizontal X-axial direction, one side of the fixed portion C1 faces the side of the inlet flange portion A2 of the iron core A, and one side of the winding portion C3 faces the outlet flange portion A3 of the iron core A.

[0110] See also Figure 2 、 5 When the first wire L1 and the second wire L2 are wound on the winding core A1, the first wire L1 and the second wire L2 are pulled over the first electrode A22 and the second electrode A23 of the inlet flange A2, and the first starting wire portion L11 and the second starting wire portion L21 are spot welded to the first electrode A22 and the second electrode A23, respectively. After spot welding, the first wire L1 and the second wire L2 are simultaneously pulled and wound on the winding core A1 and gradually wound toward the outlet flange A3. When they are adjacent to the outlet flange A3,

[0111] When the first end portion L12 of the first wire L1 is wound out from the other side of the winding core portion A1 relative to the fourth electrode A32, it will be pulled to the side of the winding core portion A1 corresponding to the fourth electrode A32 in an oblique direction and below the upper surface of the fourth electrode A32, and then the folding jig C22 is driven to move the winding abutment portion C3 between the input end flange portion A2 and the output end flange portion A3 above the iron core A, so that the end portion C33 of the front end of the winding abutment portion C3 abuts against the side of the fourth electrode A32 facing the input end flange portion A2 where the output end flange portion A3 is to be made straight in the X-axis direction, and the folding portion C34 abuts against the welding position of the first end portion L12 of the first wire L1 to be welded to the fourth electrode A32 in the Y-axis direction for positioning. At this time, the first end portion L12 of the first wire L1 is located below the bottom surface C31 of the winding abutment portion C3, as shown in FIG. Figure 4As shown, the bottom surface C31 of the abutting portion C3 is slightly lower than the upper surface of the fourth electrode A32, and the end portion C33 of the front end of the abutting portion C3 abuts against the fourth electrode A32 in the X-axis direction to make contact or maintain a clearance smaller than the diameter of the first wire L1; Figure 4 、 5 As shown, after the folding jig C is driven to move to the aforementioned position, the first end wire portion L12 will be pulled and folded against the corner between the folding portion C34 and the bottom surface C31 of the winding portion C3, and folded against the corner between the upper surface of the fourth electrode A32 and the side surface of the fourth electrode A32 facing the wire-entry end flange portion A2, and displaced toward the predetermined welding position of the fourth electrode A32, so that the first end wire portion L12 is displaced beyond the predetermined welding position of the fourth electrode A32 and exits in a straight line;

[0112] When the second end portion L22 of the second wire L2 is wound out from the side of the winding core A1 relative to the third electrode A33, it will be directly pulled to the upper surface of the third electrode A33 and displaced beyond the predetermined welding position to be wired out.

[0113] In the first embodiment of the iron core winding method and apparatus of the present invention, since the winding jig C is not located between a plurality of electrodes, when the first wire L1 is wound through the winding jig C, the portion leaning against the flange portion A3 of the outlet end is not too close to the electrode on the other side of the winding jig C, causing the high temperature during spot welding of the electrode on the other side to cause the enamel film insulation layer covering the portion of the wire leaning against the flange portion A3 of the outlet end to fall off, resulting in the conductive layer of the wire at that location being exposed, which is prone to short circuit during power-on. Furthermore, since the winding jig C is not located on the electrode of the flange portion A3 of the outlet end, it will not damage the silver end attached to the upper surface of the electrode, and during spot welding, the welding head can cover the entire silver end surface, thereby making the folding of the wire into a straight line and welding operation smoother.

After spot welding, the first wire N1 and the second wire N2 are pulled and wound on the winding core at the same time. The first wire rod N1 and the second wire rod N2 are respectively spot welded to the fourth electrode D32 and the sixth electrode D35 when the first wire rod N1 and the second wire rod N2 are wound on the flange portion D1 and gradually toward the flange portion D3 of the outlet end.

[0116] See also Figure 8 、 9 In the second embodiment of the present invention, a folding jig F as shown in the figure is used during winding. The folding jig F can be placed on the table of the winding machine equipment on one side of the X-axis center axis connected by the rotation center of a fixture E1 and a stopper E2, and is also placed between the fixture E1 and the stopper E2. Figure 1 When the core D is in the center, the folding fixture F is located on one side of the central axis R of the winding core portion D1 of the core D. The folding fixture F is driven by a driving mechanism to move in the X, Y, and Z axial directions and can be moved to the top of the core D sandwiched between the fixture E1 and the stop member E2.

[0117] The folding jig F is provided with a fixing portion F1 for linkage with a driving mechanism. The fixing portion F1 extends horizontally in the X-axis direction, and its front end is bent downward to form a first extension arm F21, a second extension arm F22, and a third extension arm F23 spaced apart from each other.

The spacing between the first winding abutment portion F31 and the second winding abutment portion F32 is relatively small, while the spacing between the second winding abutment portion F32 and the third winding abutment portion F33 is relatively wide.

[0118] The bottom surfaces F311, F321 and F331 of the first abutting portion F31, the second abutting portion F32 and the third abutting portion F33 are each slightly rectangular planes, and the upper surfaces F312, F322 and F332 thereof are each inclined planes sloping downward from the back to the front, and the front ends thereof are each rectangular slightly planar end portions F313, F323 and F333, and one side thereof is formed with a vertical planar folding portion F314, a folding portion F324 and a first folding portion F334 for folding the wire N; wherein the first abutting portion F31 also includes a folding portion F314 on the other side opposite to the folding portion F314 on one side and the second abutting portion The folding portion F324 of F32 is inclined toward an avoidance portion F315, and the avoidance portion F315 makes the end portion F313 at the front end of the first abutting portion F31 narrower and the rear end wider; the second abutting portion F32 also includes a folding portion F325 on the other side parallel to the folding portion F324 on one side; the third abutting portion F33 also includes an avoidance portion F335 on the other side opposite to the folding portion F334 on one side and inclined toward the folding portion F325 of the second abutting portion F32, and the avoidance portion F335 makes the end portion F333 at the front end of the third abutting portion F33 narrower and the rear end wider; due to the avoidance portion F315, the avoidance portion F315 The width of the end portion F313 and the end portion F333 is the same but smaller than the width of the end portion F323, so that the width between the end portion F313 and the end portion F323 is larger than the width between the first cantilever arm F21 and the second cantilever arm F22, and the width between the end portion F333 and the end portion F323 is larger than the width between the third cantilever arm F23 and the second cantilever arm F22, so as to facilitate the use of the folding portion F324 and the folding portion F325 of the second around portion F32 for wire folding. The first around portion F31, the second around portion F32 and the third around portion F33 are respectively connected to the first cantilever arm F21 and the second cantilever arm F22. 21.

When the folding jig F is displaced above the iron core D, in the horizontal X-axis direction, one side of its fixed portion F1 faces one side of the wire-inlet flange portion D2 of the iron core D, while one side of the first abutment portion F31, the second abutment portion F32, and the third abutment portion F33 each faces the wire-outlet flange portion D3 of the iron core D.

[0119] See also Figure 7 、 9 10. When the first wire N1 and the second wire N2 are simultaneously wound on the winding core D1 to form the first winding layer NA, the first wire N1 and the second wire N2 are wound to the vicinity of the outlet flange D3, wherein:
