[0002] A transformer coil is a type of coil. A transformer needs a coil to operate. According to the number of phases: (1) Single-phase transformer: used for single-phase loads and three-phase transformer groups; (2) Three-phase transformer: used for stepping up and stepping down voltage in a three-phase system. According to capacity: the coils of small transformers are generally made of insulated round copper wire, while large transformers are made of insulated flat copper wire.

[0027] Please see Figure 1-4This utility model provides a technical solution: a high-efficiency transformer coil winding device, including a workbench 1, a driving component 5, a limiting component 6, and a winding drum 4, all located on the top of the workbench 1; a sliding groove is provided on the top of the workbench 1, and a movable frame 31 is inserted inside the sliding groove; a first movable component 32 is fixedly connected to the inner side of the movable frame 31, and the movable frame 31 is located inside the winding frame 2; a positioning frame 34 is fixedly connected to the top side of the workbench 1, and a second movable component 33 is fixedly connected to the inner side of the positioning frame 34; a winding drum 4 is provided on one side of the positioning frame 34; the winding drum 4 of this structure is used for feeding copper wire; by setting the positioning frame 34, the position of the second movable component 33 can be guaranteed, ensuring the stability of the connection between the first movable component 32 and the second movable component 33; the top side of the workbench 1 is fixedly connected to... A first fixed frame 52 is connected to the worktable 1. A first motor 51 is mounted on the top of the first fixed frame 52. A drive wheel 53 is rotatably connected to the inner side of the first fixed frame 52. One end of the first motor 51 is connected to one end of the drive wheel 53. This structure allows the first motor 51 to drive the drive wheel 53 to rotate automatically, thereby enabling the drive wheel 53 to push the winding frame 2 to rotate, facilitating the winding frame 2 to perform ring-shaped winding work. A second fixed frame 62 and an electric cylinder 63 are fixedly connected to the top side of the worktable 1. The second fixed frame 62 is provided on at least two sides. A limit wheel 61 is rotatably connected to the inner side of the second fixed frame 62. One end of the electric cylinder 63 is connected to the outer wall of the second fixed frame 62. This structure allows the electric cylinder 63 to push the limit wheel 61 to automatically fit against the outer wall of the winding frame 2, thereby achieving clamping of the winding frame 2.

[0028] The drive assembly 5 includes a drive wheel 53 disposed on the top side of the worktable 1;

[0029] The limiting component 6 includes a limiting wheel 61 disposed on the top side of the workbench 1, a winding frame 2 is clamped between the limiting wheel 61 and the drive wheel 53, and a winding component 3 is disposed on one side of the winding frame 2;

[0030] The winding assembly 3 includes a first movable assembly 32 and a second movable assembly 33 disposed on the inner and outer sides of the winding frame 2. The first movable assembly 32 has slots 35 at both ends, and the second movable assembly 33 has electromagnets 38 at both ends. The slots 35 and electromagnets 38 are magnetically attracted to each other. The slots 35 in this structure are magnets. The magnetic attraction between the electromagnets 38 and the slots 35 can fix the movable slots 321 of the first movable assembly 32 and the second movable assembly 33 together, thereby ensuring the stability of the gear ring 323 during rotation. The first movable assembly 32 and the second movable assembly 33 have the same internal structure, and the first movable assembly 32 and the second movable assembly 33 are joined together to form a circular structure.

[0031] The first movable component 32 includes a movable groove 321 located inside the winding frame 2. A third fixed frame 324 is fixedly connected inside the movable groove 321. A second motor 325 is mounted on one side of the third fixed frame 324. A gear 322 is rotatably connected inside the third fixed frame 324. One side of the shaft of the second motor 325 is connected to the gear 322. The gear 322 meshes with the outer wall of the gear ring 323. This structure allows the second motor 325 to drive the gear 322 to rotate automatically. During the rotation, the gear 322 can push the gear ring 323. The automatic rotation causes the connector 36, support spring 37, and insert block 312 on the inner wall of the gear ring 323 to rotate around the outer ring of the winding frame 2. The movable groove 321 has a "C" shaped structure, and the gear ring 323 is meshed with the inner side of the movable groove 321. The gear ring 323 and the movable groove 321 form a rotatable connection. The connector 36 is fixedly connected to the inner wall of the gear ring 323. The support spring 37 is movably connected to the bottom of the connector 36. The support spring 37 has a telescopic rod 39 and a sleeve rod 310 inserted inside it. The telescopic rod 39 and the sleeve rod 310 are connected to the support spring 37. The rod 310 forms a telescopic structure. One end of the telescopic rod 39 and the sleeve rod 310 are connected to the connector 36 and the insert block 312, respectively. The two ends of the insert block 312 are threaded with positioning screws 311. This structure can limit the support spring 37 by setting the telescopic rod 39 and the sleeve rod 310, so as to prevent the support spring 37 from bending and tilting excessively during the stretching process. At the same time, the telescopic rod 39 and the sleeve rod 310 can extend and retract in coordination with the extension and retraction of the support spring 37, without affecting the movement of the support spring 37. The support spring 37 can support the insert block 312 to fit against the outer wall of the winding frame 2. One end of the support spring 37 is connected to the insert block 312, and one end of the copper wire on the winding drum 4 is inserted into the insert block 312. The first movable component 32 and the second movable component 33 of this device are spliced ​​together to form a circular structure with their movable grooves 321 and toothed rings 323. The first movable component 32 and the second movable component 33 are equipped with a set of connectors 36, support spring 37, telescopic rod 39, sleeve rod 310, positioning screw 311 and insert block 312.

[0032] Working principle: When using this high-efficiency transformer coil winding equipment, firstly, insert one end of the copper wire on the winding drum 4 into the insert block 312 and tighten it with the positioning screw 311. Next, place the outer wall of the winding frame 2 near the second movable component 33, so that the outer wall of the winding frame 2 near the second movable component 33 is in contact with the outer wall of the drive wheel 53. Then, the electric cylinder 63 pushes the limit wheel 61 to contact the outer wall of the winding frame 2, clamping and fixing the winding frame 2. After the winding frame 2 is fixed, slide the movable frame 31 on the top of the worktable 1, so that the first movable component 32 and the second movable component 33 on the inner side of the movable frame 31 are spliced. Then, the slot 35 is magnetically attracted and connected to the electromagnet 38, and then the winding process begins. During the winding process, the insert 312 remains in contact with the outer wall of the winding frame 2 under the support of the support spring 37. During winding, the second motor 325 drives the gear 322 to rotate. As the gear 322 rotates, it pushes the gear ring 323 to rotate. When the gear ring 323 rotates, the connector 36, support spring 37, telescopic rod 39, sleeve rod 310, positioning screw 311, insert 312, and copper wire on the inner side of the gear ring 323 are wound around the winding frame 2. At the same time, the first motor 51 drives the drive wheel 53 to rotate, which in turn drives the winding frame 2 to rotate, thereby achieving rapid winding. After winding is completed, one end of the copper wire is removed from the insert 312 and the other end of the copper wire is cut off.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
