[0024] Embodiment: A device for detecting the winding of an electric wire on a magnetic ring, comprising an operating platform 1, a magnetic ring fixture 2, a bus fixture 3, a single wire fixture 4, an inductance testing device 5 and a control system 6, wherein the magnetic ring fixture 2, the bus fixture 3 and the single wire fixture 4 can be fixedly installed on the operating platform 1 respectively, the magnetic ring fixture 2 can fix and position the magnetic ring 7 to be wound, the bus fixture 3 is located on one axial side of the magnetic ring 7 fixed and positioned by the magnetic ring fixture 2, and a plurality of single wire fixtures 4 are located on the other axial side of the magnetic ring 7 fixed and positioned by the magnetic ring fixture 2 The distances between each of the single wire holders 4 and the axial end face on the other side of the magnetic ring 7 are the same or different. The bus holder 3 can fix and position one end of the multiple wires 8 in parallel. The other ends of the multiple wires 8 are respectively wound around the magnetic ring 7 fixed on the magnetic ring holder 2 for a set number of turns and then fixed and positioned on each of the single wire holders 4 one by one. The inductance testing device 5 can detect the inductance value of the magnetic ring 7 in real time. The inductance testing device 5 is electrically connected and communicated with the control system 6. The control system 6 can determine whether the magnetic ring 7 is qualified according to the inductance value measured by the inductance testing device 5.

[0025] When winding multiple wires 8 on the magnetic ring 7, first fix the magnetic ring 7 through the magnetic ring fixer 2, then fix and position one end of the multiple wires 8 to be wound on the bus fixer 3 in a parallel arrangement, and then select a wire 8 in sequence, wind the other end of the wire 8 on the magnetic ring 7 for a specified number of turns and then fix it on the corresponding single wire fixer 4. When all the wires 8 are wound on the magnetic ring 7, both ends of each wire 8 remain in a fixed state. At this time, each wire 8 is wound around the magnetic ring 7 in a set tightness, and the wires 8 wound on the magnetic ring 7 are tied and bound with a rolling belt. The above structure can ensure that each wire 8 is quickly and accurately wound around the magnetic ring 7, and after the winding is completed, it is kept in the tightness state required by the design for binding. The subsequent wires 8 will not be affected by the previously wound wires 8 when they are wound. The winding efficiency is high. After the winding, the wires 8 are automatically in a stable tightness state. The distance between the two ends of the wires 8 extending out of the outer side of the magnetic ring 7 can be designed on the operating platform 1 according to the design requirements. The bus holder 3 and the positions of each single wire holder 4 can be designed. The above device also detects the inductance value of the magnetic ring 7 in real time during the winding process of the magnetic ring 7 to avoid electromagnetic unqualifiedness and ensure the quality of the magnetic ring 7 winding products.

[0026] The magnetic ring fixer 2 includes a magnetic ring positioning base 21, a magnetic ring clamping jaw 22 and a magnetic ring clamping drive device 23. The magnetic ring positioning base 21 is fixedly installed on the operating platform 1. The two magnetic ring clamping jaws 22 can be installed on the magnetic ring positioning base 21 in a relatively slidable manner. The opposite side walls of the magnetic ring clamping jaws 22 are respectively formed with clamping surfaces matching the shape of the magnetic ring 7. The magnetic ring clamping drive device 23 can drive the two magnetic ring clamping jaws 22 to move relative to each other to clamp the two opposite outer surfaces of the magnetic ring 7 or loosen the outer surface of the magnetic ring 7. The control system 6 controls the start and stop of the magnetic ring clamping jaw 22 drive device. The magnetic ring 7 is positioned by clamping the outer ring of the magnetic ring 7. The magnetic ring 7 is positioned firmly and accurately. After the magnetic ring 7 is clamped, the winding part is located in the gap between the two magnetic ring jaws 22, which has no effect on the winding of the magnetic ring 7. It is best to provide a magnetic ring jaw 22 guide rail 26 on the base for guiding the movement of the magnetic ring jaw 22. The magnetic ring clamping drive device 23 is best a cylinder. The control system 6 controls the piston movement of the cylinder to drive the magnetic ring jaw 22. In addition, the magnetic ring jaw 22 drive device can also be a motor and a screw nut mechanism or a quick clamping mechanism. In addition to the above-mentioned jaw clamping structure, the magnetic ring fixture 2 can also be positioned by other positioning methods, such as axial clamping, etc. This is an equivalent replacement structure that can be easily thought of by technical personnel in this field based on this patent.

[0027] The two magnetic ring clamps 22 are installed on the magnetic ring positioning base 21 so as to move linearly relative to each other in the horizontal direction. The clamping surfaces on the opposite side walls of the magnetic ring clamps 22 are arc surfaces, and the lower ends of the arc surfaces can be supported on the lower side of the outer side surface of the circumference of the magnetic ring 7. The upper ends of the arc surfaces provide a horizontal or inclined downward clamping force to the outer side wall of the magnetic ring 7. A layer of elastic pad 24 is fixed and compounded on the clamping surface of the magnetic ring clamps 22. In the above structure, one magnetic ring clamp 22 is fixed on the magnetic ring positioning base 21 as the positioning reference of the magnetic ring 7, and the other magnetic ring clamp 22 is used to slide and clamp the magnetic ring 7. After the magnetic ring 7 is placed on the arc surface between the two magnetic ring clamps 22, the arc surface on the upper side of the magnetic ring clamp 22 supports the outer arc surface on the lower side of the magnetic ring 7, and then the magnetic ring clamp 22 moves to clamp the magnetic ring 7, so as to achieve accurate clamping and positioning of the magnetic ring 7. When the magnetic ring 7 is clamped, it is contacted through the elastic pad 24, so as to avoid damage to the outer ring of the magnetic ring 7 and ensure the stable clamping of the magnetic ring 7.

[0028] The magnetic ring positioning base 21 is respectively hinged with a blocking rod 25 on both axial side walls of the fixed magnetic ring 7. The blocking rod 25 can be rotated to any angle position for stopping and positioning, and the blocking rod 25 can be tightly pressed against the two axial side walls of the fixed magnetic ring 7. While the outer circumferential side surface of the magnetic ring 7 is clamped, its two axial end surfaces are also positioned by the blocking rod 25, ensuring the accurate positioning of the magnetic ring 7. When in use, only the blocking rod 25 needs to be rotated to achieve the blocking and limiting of the axial end surface of the magnetic ring 7, and the blocking and limiting position can be adjusted to avoid interference with winding.

[0029] The bus holder 3 includes a bus fixing base 31, an upper jaw 32, a lower jaw 33 and a bus jaw driving device 34. The upper jaw 32 and the lower jaw 33 are installed on the first fixing seat so as to be able to move relative to each other in the vertical direction. The upper jaw 32 and the lower jaw 33 extend horizontally and straightly on a vertical plane parallel to the axial end face of the fixed magnetic ring 7. A clamping space for the parallel arrangement of each wire 8 is formed between the upper jaw 32 and the lower jaw 33. The bus jaw driving device 34 drives the upper jaw 32 and the lower jaw 33 to move relative to each other to clamp or release each wire 8 at the same time. The control system 6 controls the start and stop action of the bus jaw driving device 34. The lower clamp 33 is preferably fixed on the bus fixing seat, and the upper clamp 32 moves up and down to clamp one end of all parallel wires 8. The lower clamp 33 forms a positioning reference for one end of the wire 8. In order to improve the stability of the clamping of the wire 8 between the upper clamp 32 and the lower clamp 33 and prevent it from being pulled out, it is best to set a concave and convex structure on the upper clamp 32 and the lower clamp 33 to increase friction. The concave and convex pattern preferably extends in the direction perpendicular to the extension of the wire 8. The bus clamp driving device 34 is preferably a cylinder. The control system 6 controls the piston movement of the cylinder to realize the driving of the upper clamp 32. In addition, the bus clamp driving device 34 can also be a motor and a screw nut mechanism or a quick clamp.

[0030] The single wire holder 4 includes a single wire fixing base 41, a left clamping jaw 42, a right clamping jaw 43 and a single wire clamping jaw driving device 44. The left clamping jaw 42 and the clamping jaw can be installed on the wire 8 fixing base so as to move relative to each other in the horizontal direction. A clamping space for clamping and accommodating the single wire 8 is formed between the left clamping jaw 42 and the right clamping jaw 43. The single wire clamping jaw driving device 44 drives the left clamping jaw 42 and the right clamping jaw 43 to move relative to each other to clamp or simultaneously release the corresponding single wire 8. The control system 6 controls the start and stop actions of each single wire clamping jaw driving device 44. The other end of each wound wire 8 is clamped and fixed by the left jaw 42 and the right jaw 43 of a single wire holder 4. The left jaw 42 and the right jaw 43 are opened in the horizontal direction to facilitate the direct top-down insertion of the wire 8 after the winding is completed. The single-wire clamp drive device 44 is preferably a cylinder. The control system 6 controls the piston movement of the cylinder to drive the left jaw 42 and the right jaw 43. In addition, the single-wire clamp drive device 44 can also be a motor and a screw nut mechanism or a quick clamp mechanism.

[0031] A bus fixed-length contact plate 35 and a single-line fixed-length contact plate 45 are also provided. The bus fixed-length contact plate 35 is fixedly installed on the operating table. The bus fixed-length contact plate 35 and the bus fixture 3 are arranged in parallel and spaced relation to the fixed magnetic ring 7. A fixed-length contact surface 351 corresponding to each wire 8 is formed on a side wall of the bus fixture 3 facing downward. The distances between each fixed-length contact surface 351 and the bus fixture 3 are equal or unequal. One end of each wire 8 can closely contact each fixed-length contact surface 351 one by one. A plurality of single-line fixed-length contact plates 45 are fixedly installed on the operating platform 1 one by one with each single-wire fixture 4. The surface of the single-wire fixed-length contact plate 45 facing the single-wire fixture 4 is a vertical direct contact surface. The other ends of each wire 8 after winding can closely contact each single-wire fixed-length contact plate 45 facing the single-wire fixture 4. When one end of the wire 8 is placed in the bus holder 3, first, one end of each wire 8 is pressed tightly against each fixed-length contact surface 351 corresponding to the bus fixed-length contact plate 35, so that the length of the wire 8 extending out of one end of the magnetic ring 7 is fixed, and then the bus holder 3 clamps and fixes all the wires together. After the other end of each wire is wound, when it enters the single wire holder 4, the other end face of each wire 8 is pressed tightly against the corresponding single-wire fixed-length contact plate 45 for fixed length, and then the corresponding single wire holder 4 fixes and positions the wire 8, so that the tightness of the winding of the wire 8 can be ensured to meet the design requirements, and at the same time, the length of the two ends of the wire 8 extending out of the axial ends of the magnetic ring 7 can be ensured to be the designed length, without manual adjustment, ensuring that the coils on all the winding magnetic rings 7 are loose The tightness and the extension length of both ends of the wire 8 are consistent, and both can meet the design requirements. The automatic fixed length avoids repeated adjustments by workers, greatly improves the winding efficiency of the magnetic ring 7, and effectively improves the quality of the magnetic ring 7 winding products. Among them, the bus fixed-length contact plate 35 and the single-line fixed-length contact plate 45 can adjust the axial distance between them and the magnetic ring holder 2, so as to adapt to the lead-out distance of the wire 8 when winding different magnetic rings 7. The adjustment structure can be to set a contact plate fixing seat 36 on the operating platform 1, and set a contact plate slide that can slide along the axial direction of the fixed magnetic ring 7 on the contact plate fixing seat. The contact plate slide 37 is connected to the line fixed-length contact plate or the single-line fixed-length contact plate 45. A long strip hole 371 can be set on the contact plate slide, and the connecting screws are used to realize locking or loosening adjustment.

The resistance measuring instrument 9 can measure the conductive resistance of each wire. The resistance measuring instrument 9 is electrically connected and communicated with the control system 6. The control system 6 can judge whether the wire 8 is qualified according to the resistance value of the wire 8 measured by the resistance measuring instrument 9. After the winding on the magnetic ring 7 is completed, the resistance measuring instrument 9 can also be used to test the resistance of each wire 8 to ensure that each wire is not damaged and the quality of the finished product is guaranteed.

[0034] The control system 6 is preferably also provided with a control switch 10, and a worker presses the control switch to control the magnetic ring clamping drive device 23, the bus clamping drive device, the single-line clamping drive device, the inductance test device 5 and the resistance measuring instrument 9 to start and stop working.
