Description

Method and device for winding wire around iron core

The present invention relates to a method and device for winding wires around an iron core, and more particularly to a method and device for winding wires around an iron core with flanges at both ends, a winding core between the two flanges, and an electrode portion only located on one of the flanges.

Generally, there are many types of electronic components such as transformers or inductors formed by winding wires on an iron core. The most common types include two: one is to use a ring iron core, and the other is to use an I-shaped iron core. Among them, the prior art uses an I-shaped iron core to wind the wires. The I-shaped iron core is usually provided with a wire input end flange and a wire output end flange at both ends, with a winding core part in between. Most of them use a rotating seat that can be rotated intermittently. Multiple workstations are respectively provided at equal angles outside the rotating seat to perform various operations including feeding, winding, cutting, waste wire removal, welding, etc. , unloading and collecting processes. When winding, the wire-inlet end flange of the iron core is usually clamped by a clamp, and the other wire-outlet end flange is supported. The wire is drawn by a winding needle through the electrode portion on the upper surface of the wire-inlet end flange of the clamp end and is first spot-welded and fixed. The clamp is then linked to the iron core to rotate to wind the wire on the winding core. Then the winding needle again draws the wire through the wire-outlet end flange, and the wire is spot-welded and fixed on the electrode portion on the upper surface of the wire-outlet end flange. The iron core after the wire winding is completed is discharged and collected at a unloading and collecting workstation.

The above-mentioned prior art of winding wires on an iron core is only applicable to the case where the electrode portion of the iron core is located at the wire inlet flange and the wire outlet flange respectively, and both are located on the upper surface. If the electrode portion of the iron core to be wound is only on one flange, that is, the wire inlet and the wire outlet are both on the same flange, and the electrode portion is not located on the upper surface, If the electrode is located on the side of the flange end, the above-mentioned prior art cannot be implemented; therefore, the patent application No. 202242924 "Method and device for winding wires on iron core" provides a solution for winding wires on such iron cores, which winds two layers of wires on the winding core, but the patent application uses a flange without an electrode portion. The first layer of wires on the winding core is wound from the side of the clamped flange, and then gradually wound to the side of the flange with the electrode. When winding the second layer, it is necessary to wind from the side of the flange with the electrode to the side of the clamped flange. When the second layer of wires is wound, the wires are just located on the side of the clamped flange. In order to weld the wire to the electrode part, the wire must be pulled from the flange side where the electrode is provided, which not only wastes the process time, but also makes the wire pulled from the flange side where the electrode is provided cross the outer surface of the wound coil, causing the wire arrangement to cause the wire package to be large, which is easy to cause electrical abnormalities! Since the patent case uses a winding needle to pull the wire, the wire is input and passed through the winding needle, and one end of the wire is first clamped by the wire clamp on one side of the clamp. Therefore, if the winding is changed from the flange side with the electrode part to the clamped flange side, there will be a problem that the winding needle rotates from the outside to the inside and hits the wire tied to the wire clamp on one side. Therefore, the technology still needs to be improved!

Therefore, the object of the present invention is to provide a method for winding a wire around an iron core that can improve at least one disadvantage of the prior art.

Please refer to Figures 5 to 6, 9 to 10. The winding clamp mechanism C31 is provided with a swing arm C314. One end of the swing arm C314 is fixed to the rotating shaft C3111 of the driving member C311 and is driven to swing. The other end is provided for the winding clamp C312. The axis of the rotating shaft C3111 and the axis of the clamp B1 are on the same axis in the second axis direction Y. The winding clamp C312 is provided with rods A first winding clamp C3121 and a second winding clamp C3122 are respectively arranged on the swing arm C314 in a horizontal direction along the second axis Y, and are spaced from side to side and parallel to each other. One end of the swing arm C314 can be driven by the driving member C311 to rotate around the rotation axis C3111, and the winding clamp C312 at the other end of the swing arm C314 is connected to the swing arm C314 to rotate downward at a rotation radius interval. The rotating shaft C3111 rotates, and when viewed from the winding clamp mechanism C31 toward the clamp B1 along the second axis Y, the winding clamp C312 rotates counterclockwise, wherein the first winding clamp C3121 is located at the front side of the rotating direction, and the second winding clamp C3122 is located at the rear side of the rotating direction, and the distance between the winding clamp C312 and the axis center of the rotating shaft C3111 is the rotation of the winding clamp C312. Radius, the rotation radius is greater than the distance from the axis of the clamp B1 to the first wire clamp B21 or the second wire clamp B22; when the clamp B1 clamps the iron core A, the iron core A protrudes from the first wire clamp B21 or the second wire clamp B22 at the position of the second axis Y, and when the winding clamp C312 clamps the wire and rotates around the iron core A, it will not be interfered by the first wire clamp B21 or the second wire clamp B22; The first clamp C3121 and the second clamp C3122 have the same structure. The first clamp C3121 is taken as an example for explanation. It includes a pivot rod C31211 pivoted by the swing arm C314. The pivot rod C31211 has a front stopper C31212 at one end facing the clamp B1. The other end of the pivot rod C31211 located at the other side of the swing arm C314 is provided with a rear stopper C31213. The pivot rod C31211 between the front stopper C31212 and the swing arm C314 is provided with a clamp sleeve C31214. The outer sleeve of the pivot C31211 between the baffle C31213 and the swing arm C314 is an elastic member C31215 such as a coil spring. When the rear baffle C31213 is pushed and compresses the elastic member C31215, the pivot C31211 will be displaced toward one end of the clamp B1, so that the front baffle C31212 is pushed outward and maintains a gap between the end of the clamp sleeve C31213 for clamping the first wire L1. Similarly, the second winding clamp C3122 also provides a gap for clamping the second wire L2.

The operating member C313 for performing the loosening and clamping operations on the winding clamp C312 is located on one side of the rotating shaft C3111. When the swing arm C314 is rotated to one side of the operating member C313 and is in a horizontal state as shown by the imaginary line in FIG. 10, the operating member C313 is located at the rear end of the pivot rod C31211 of the winding clamp C312, and a distance is maintained between the operating member C313 and the rear stopper C31213 of the pivot rod C31211 in the second axial direction Y. 313 is in the shape of a plate and driven by a driving member C3131 to move in the second axis direction Y to push the rear stopper C31213, so that the arm C31211 moves toward one end of the clamp B1 to form the first winding clamp C3121 to provide the clearance for clamping the first wire L1, thereby also producing the function of releasing the first wire L1 when clamped. Similarly, the operating member C313 also forms the second winding clamp C3122 to provide the clearance for clamping The residual gap of the second wire L2 is held, and thereby the function of releasing the second wire L2 when clamped can be generated; the driving member C311 driving the first clamp C3121 and the second clamp C3122 to rotate and the driving member C3131 driving the operating member C313 in the clamping mechanism C31 are jointly arranged on a carrier C315 and can be synchronously displaced, so the clamp C312 and the operating member C313 are linked and can be synchronously displaced. ; wherein the synchronous displacement includes the carrier C315 being driven by a driving member C316 (FIG. 5, 6) such as a slide cylinder to link the winding clamping mechanism C31 to make a displacement in the first axial direction X, and being driven by a driving mechanism C317 such as a slider on a screw-driven slide rail to link the winding clamping mechanism C31 to make a displacement in the second axial direction Y together or one of them; the winding clamping mechanism C31 and the guide needle mechanism C32 are jointly arranged on the carrier C34 whose machine table T is horizontal.

Please refer to Figures 1, 3, 9, 11, and 12. The following embodiments of the present invention are explained by winding two wires. Similarly, the same can be applied to winding one wire. When the iron core A is fed into the feeding and unloading station C1, the second flange A3 without any electrode portion A4 is clamped by the clamp B1, so that the winding core portion A1 and the first flange A2 with the electrode portion A4 located on the other side of the winding core portion A1 are protruded outside the clamp B1. When the clamp B1 clamps the iron core When A is intermittently rotated to the winding station C3 for winding, the first wire L1 passes through the first guide needle C3211 and is clamped by the first winding clamp C3121 of the winding clamp C312; the second wire L2 passes through the second guide needle C3212 and is clamped by the second winding clamp C312 of the winding clamp C312. 22 clamping; before winding, the winding clamp mechanism C31 is moved to the same axis of the axis of the rotating shaft C3111 of the rotary arm C314 and the axis of the clamp B1 in the second axis direction Y; the winding clamp C312 pulls the first wire L1 and the second wire L2 as shown in the figure, with the first wire L1 on the top and the second wire L2 on the bottom in an inclined direction of the upper left and lower right, and moves down through the cutting piece C331 of the cutting mechanism C33 and the bottom of the clamp B1 at a distance, so that the winding clamp C312 pulls one end of the first wire L1 and the second wire L2 to move to the winding position P together.

Please refer to Figures 1, 2, 9, and 13. After the orifice C312 reaches the winding position P, one end of the swing arm C314 of the orifice mechanism C31 is driven by the driving member C311 to rotate around the rotation axis C3111, so that the orifice C312 rotates counterclockwise, so that the first orifice C312 rotates counterclockwise. The first wire L1 clamped by the first winding clamp C3121 first touches the lower edge of the winding core A1 of the wire entry side A252 of the iron core A near the first flange A2, and then the second wire L2 clamped by the second winding clamp C3122 also touches the lower edge of the wire entry side A252 of the iron core A near the first flange A2. The lower edge of the winding core A1; when the swing arm C314 is continuously driven to swing and the rotating frame B23 of the wire clamp mechanism B2 is also linked with the clamp B1 clamping the iron core A to rotate counterclockwise in the same direction, the driving mechanism C317 drives the winding clamp mechanism C31 to move in the second axial direction Y, and the winding clamp C312 will drive the first wire L1 and the second wire L2 toward the second flange A3 of the iron core A to be wound around the winding core A1 for a predetermined number of turns to form a first layer of coils, and then from the second flange A3 side to the first flange A2 side to be wound around the winding core A1 for a predetermined number of turns to form a second layer of coils.

Please refer to Figures 6, 11, and 14. After winding is completed, the driving member C316 drives the winding clamp mechanism C31 to move in the first axial direction X, and the driving mechanism C317 drives the winding clamp mechanism C31 to move in the second axial direction Y. At the same time, the winding clamp C312 drives the first wire L1 and the second wire L2 to move to and embed the first wire clamp B21. The first wire L1 and the second wire L2 are clamped in the two clamps B211 and B212, and at the same time, the guide needle mechanism C32 is driven to link the first guide needle C3211 and the second guide needle C3212 of the guide needle C321 to pull the other ends of the first wire L1 and the second wire L2 to move to and embed in the two clamps B221 and B222 spaced apart on the upper and lower parts of the second wire clamp B22 to be clamped.

Please refer to Figures 1, 2, 9 to 11, and 15. After both ends of the first wire L1 and the second wire L2 are clamped and fixed, the operating member C313 is driven by the driving member C3131 to move in the second axial direction Y to push the rear stopper C31213 of the winding clamp C312, so that the pivot C31211 moves toward one end of the clamp B1, and the front stopper C31212 is pushed outward to form a gap with the end of the clamp sleeve C31213, so that the winding clamp C312 is loosened from the first wire L1. Similarly, the winding clamp C312 also releases the clamping of the second wire L2 synchronously; after releasing the clamping of the first wire L1 and the second wire L2, the winding clamp C312 is driven to move between the guide needle mechanism C32 and the cutting mechanism C33, and then the cantilever C322 of the guide needle mechanism C32 is driven to move downward, thereby linking the first guide needle C3211 and the second guide needle C3212 to move the first wire L1 and the second wire L2 between the guide needle mechanism C32 and the cutting mechanism C33. The lower belt of the second wire L2 is delivered to the first winding C3121 and the second winding C3122 of the winding C312, and when the operating member C313 is driven by the driving member C3131 to move backward in the second axial direction Y, the rear stopper C31213 of the winding C312 is released, so that the arm C31211 moves toward the opposite end of the clamp B1, and the front stopper C31212 returns to its original position and clamps against the end of the clamp sleeve C31213, so that the winding C312 is clamped to the first wire L1 therebetween. Similarly, the winding clamp C312 also synchronously clamps the second wire L2, and then the driving member C332 of the cutting mechanism C33 drives the cutting member C331 to move upward to cut the first wire L1 and the second wire L2 between the winding clamp C312 and the second wire clamp B22.

Please refer to Figures 1, 2, 9 to 11, and 16. After the first wire L1 and the second wire L2 between the winding clamp C312 and the second wire clamp B22 are disconnected, the driving member C332 of the cutting mechanism C33 drives the cutting member C331 to move downward, and the winding clamp C312 clamping the first wire L1 and the second wire L2 is driven to move to the axis of the rotating shaft C3111 of the swing arm C314 and the axis of the clamp B1 on the same axis of the second axis Y, and the winding clamp C31 2 and pull the first wire L1 and the second wire L2 as shown in the figure, with the first wire L1 on the top and the second wire L2 on the bottom, in an inclined direction from left to right, and extend through the cutting piece C331 of the cutting mechanism C33 and the clamp B1 at the original position P where winding is to be started at a certain interval; then the iron core A that has completed winding will be intermittently rotated together with the clamp B1 and the wire clamp mechanism B2 to the first winding station C4 for the next operation.

The method and device for winding wire with an iron core of the present invention is that when winding, the wire is passed through a guide needle of a guide needle mechanism and clamped by a winding clamp mechanism. The clamped wire is wound around the axis of the clamp as the rotation center to perform winding. Therefore, unlike the previous technology that uses a winding needle to pull the wire, The wire is input and passed through the winding needle, and one end of the wire is first clamped by the wire clamp on one side of the clamp. In the embodiment of the present invention, when winding, one end of the wire is not first clamped by the wire clamp on one side of the clamp, but the wire end is sent to the wire clamp after winding. Therefore, there will be no problem that the winding needle rotates from the outside to the inside and hits the wire tied to the wire clamp on one side. Therefore, it can be implemented in making the wire The wire enters from the wire entry side of the winding core near the first flange side, and winds the winding core toward the second flange for a predetermined number of turns to form the first layer of coils, and then winds the winding core from the second flange side to the first flange side for a predetermined number of turns to form the second layer of coils, and then the wire exits from the wire exit side adjacent to the first flange side in the winding method, so as to avoid the wire arrangement causing the wire package to be large!
