Description

Technical Field

[0001] The invention belongs to the technical field of transformer coil processing, and in particular relates to a high-efficiency transformer coil winding device. Background Art

[0002] Transformer coil winding is the core process of transformer manufacturing, which has a significant impact on the economic and technical indicators of the transformer, such as performance, size, loss and weight. These economic and technical indicators are directly related to important quality indicators such as mechanical properties, insulation properties and heat resistance of the transformer.

[0003] At present, the common transformer winding machines are mainly used for winding high and low voltage coils of transformers, corresponding to two different wire gauges: round wire and flat wire. The functional configuration of the transformer winding machine should meet the winding process of these two wire gauges. Being familiar with the winding process of conventional transformer coils and using the transformer winding machine correctly is the prerequisite for winding qualified coils.

[0004] During the winding process, the winding machine needs to maintain a certain speed while being able to start and stop quickly. In addition, the enameled wire needs to have a certain tension so that the wire can fit the winding die and the consistency of the gap between the coil layers is controlled within the allowable range.

[0005] However, in the existing process of winding the transformer coil, the wires cannot be closely attached to each other, resulting in inaccurate winding of the transformer coil and affecting the operation of the transformer. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides a high-efficiency transformer coil winding device, including a mounting base 1, on which a winding mounting fixture 2 is provided, the winding mounting fixture 2 is horizontally arranged on the mounting base 1, and a support platform 3 for supporting the coil is provided on the mounting base 1, and a wire feed guide structure 4 is also provided on the side of the mounting base 1, and the wire feed guide structure 4 is arranged toward the support platform 3, and a winding tight fitting structure 5 is also provided on the mounting base 1, and the winding tight fitting structure 5 can fit the wire tightly on the coil of the transformer, and an automatic rotation mechanism is also provided in this process, and the automatic rotation mechanism can drive the coil on which the wire is placed to rotate, which is not shown in the figure. The coil structure has a hollow shape in the middle, which can enable the winding mounting fixture 2 to support and fix it.

[0031] Specifically, the winding installation fixing part 2 includes a horizontally arranged installation frame 21, and a bidirectional screw rod 22 is provided on the installation frame 21 and is rotatably connected thereto, and a transmission motor 23 is provided on the installation frame 21 and is transmission-connected to the bidirectional screw rod 22, and two sliders 24 are provided on the bidirectional screw rod 22 and are threadedly connected thereto, and each of the sliders 24 is provided with a limiting fixing part 20; the limiting fixing part 20 includes a lifting electric cylinder 201, and a lifting frame 202 is provided on the telescopic end of the lifting electric cylinder 201, and a fixed block 203 is provided in the lifting frame 202 and is slidably matched therewith, and springs 204 are provided at both ends of the fixed block 203 and are in contact with the lifting frame 202, and a rotating end 205 is provided on the fixed block 203; the rotating end 205 can be a rotating wheel, a rotating ball, and a rotating structure that can rotate on the fixed block 203.

[0032] In this embodiment, after the coil is placed on the support table 3, the transmission motor 23 works to drive the bidirectional screw rod 22 to rotate on the mounting frame 21. The rotation of the bidirectional screw rod 22 can drive the positions of the two sliders 24 to be close or far away. According to the size of the hollow structure in the middle of the coil, the distance between the two sliders 24 is adjusted so that the two sliders 24 can support and fix the coil. In the process of coil winding, the fixing block 203 can make the rotating end 205 contact the inside of the coil under the action of the two mutually conflicting springs 204. In the process of the coil rotating, the coil can be moved more smoothly on the rotating end 205, so that the rotation effect is better.

[0033] During the winding process, the lifting electric cylinder 201 can drive the lifting frame 202 to move upward synchronously with the four electric telescopic rods 31 at the bottom of the support platform 3, so that during the winding process, the position of the coil can be continuously adjusted upward or downward according to the needs of winding, so that the wire fits tightly on the coil. While the coil is rotating, the coil can also be moved upward according to the distance the coil moves, so that the coil can better perform the wire winding operation.

[0034] Specifically, four electric telescopic rods 31 are provided at the bottom of the support platform 3, four notches 32 are provided on the support platform 3, each of the notches 32 is provided with a rotating plate 33, and the rotating plate 33 is rotatably connected to the notch 32, and four support plates 34 are provided on the support platform 3, and the support plates 34 are rotatably connected to the support platform 3, and the support plates 34 are correspondingly arranged with the rotating plates 33.

[0035] In this embodiment, after the coil is placed on the support platform 3, the coil can be rotated on the support platform 3 to perform the wire winding operation. When winding coils of different sizes, the rotating plate 33 can be rotated out from the notch 32 so that the coil is located above the rotating plate 33. Thereafter, the support plate 34 is rotated out from the bottom of the support platform 3 to support the position of the rotating plate 33 so that the coil can be better supported for rotation on the support platform 3.

[0036] Specifically, the inlet wire guide structure 4 includes a guide rod 41 , a rotatably connected guide roller 42 is provided on the guide rod 41 , a notch 44 is provided on the guide roller 42 , and a locking threaded ring 43 is provided at the bottom and top of the guide roller 42 .

[0037] In this embodiment, when guiding the wire, the wire can be passed through the notch 44 on the guide roller 42 so that the wire can be transported to the coil through the notch 44, and the coil can be rotated by the automatic rotating mechanism to perform the winding operation on the wire.

[0038] Specifically, the winding tight fitting structure 5 includes a mounting frame 51, on which a driving motor 52 is provided, on which a threaded rod 53 is provided, and the bottom of the threaded rod 53 is connected to the main shaft of the driving motor 52, on which a sliding rod 54 is provided, on which a lifting block 55 threadedly connected is provided, and the lifting block 55 is slidably matched with the sliding rod 54, and the lifting block 55 is provided with a winding resistance member 6.

[0039] During the winding process, the wire needs to fit tightly on the coil one circle at a time. During this process, the resistance wheel 67 needs to move up and down as the position of the wire moves up and down. At this time, the drive motor 52 drives the threaded rod 53 to rotate on the mounting frame 51. The rotation of the threaded rod 53 can drive the lifting block 55 to move up and down on the sliding rod 54, thereby driving the position of the winding resistance member 6 to move up and down, and fitting the wire tightly to the coil.

[0040] Specifically, the winding resistance member 6 includes an electric horizontal slide 61 horizontally arranged on the lifting block 55, a moving platform 62 is provided on the moving end of the electric horizontal slide 61, a rotating motor 63 is provided at the bottom of the moving platform 62, a rotating disk 64 is provided on the rotating motor 63, two slide rails 65 are provided on the moving platform 62, and sliding blocks 66 are provided on the two slide rails 65. The sliding blocks 66 are slidably matched with the two slide rails 65, and a resistance wheel 67 is provided on the sliding block 66. A hinged connecting plate 68 is provided between the sliding block 66 and the rotating disk 64.

[0041] In this embodiment, when the wire is pressed and abutted, the electric horizontal slide 61 can move the position of the abutment wheel 67 to the place where the wire is wound on the coil, and the rotating motor 63 drives the rotating disk 64 to rotate, thereby driving the sliding block 66 to move on the two slide rails 65 through the connecting plate 68, and moving the position of the abutment wheel 67 toward the winding place, so that the wire fits tightly on the coil, and as the coil is wound, the electric horizontal slide 61 can drive the position of the movable table 62 to move, and drive the position of the abutment wheel 67 to move. During the continuous winding, as the diameter of the wire on the coil continues to increase, the position distance of the abutment wheel 67 can be adjusted, and the position of the abutment wheel 67 can also be adjusted according to the needs of winding coils of different sizes.

[0042] The above description is only an embodiment of the present invention and is not intended to limit the present invention.
