Description

Technical Field

[0001] This application relates to the technical field of transformer production, and particularly relates to a wire winding device for transformers. Background Art

[0002] A transformer is a static electrical device that uses the principle of electromagnetic induction to transfer electrical energy from one circuit to another, and is applied in fields such as power transmission and distribution, electronic devices, and electrical equipment. One of the core components of a transformer is the winding. A certain number of turns of coils need to be wound on the winding sleeve, and the coils also come in different types. For example, round wires, flat wires, and flat enameled wires, etc. An induction coil is made by winding the coils.

[0003] For example, the Chinese patent document with the publication number CN116206890B discloses a multi-angle automatic wire winding device for a micro-transformer coil, which includes a transformer wire winding central axis, and also includes a wire winding angle adjustment module, a uniform wire winding guiding module, and a matching adjustment and fixing module. The top of the wire winding angle adjustment module is fixedly connected with the uniform wire winding guiding module, and the top of the uniform wire winding guiding module is slidably connected with the matching adjustment and fixing module; the wire winding angle adjustment module includes a base table, a first motor, and a transverse positioning table. The bottom end of the base table is fixedly connected with the first motor by screws, and the top end of the first motor is fixedly connected with the transverse positioning table. When the fastening is completed, when winding the wire around the transformer wire winding central axis at a certain angle according to the micro-transformer, the first motor can be controlled to drive the transverse positioning table to rotate according to the required wire winding angle, so that the wire winding body forms different wire winding angles relative to the axis in the long side direction of the transformer wire winding central axis during the process of contacting the transformer wire winding central axis, and then the purpose of wire winding is achieved.

[0004] In the above related technology, the positioning table is rotated by the rotation of the first motor, and the row positioning and pulling structure moves along the length direction of the central axis, so that the wire winding body is evenly wound on the central axis along the length direction of the central axis. However, during the wire winding process, when the width of the wire becomes wider or narrower, two adjacent wires in the same turn may not be in close contact or may overlap, resulting in the problem of uneven wire arrangement distribution, which causes incomplete coupling of the inter-turn magnetic flux and affects the electromagnetic performance of the transformer. Summary of the Invention

[0005] This application provides a wire winding device for transformers, aiming to solve the problem that two adjacent wires are not in close contact or overlap in the related technology.

[0006] The wire winding device for transformers provided by this application adopts the following technical solutions: A wire winding device for a transformer, comprising a mounting frame and a mounting shaft rotatably connected to the mounting frame. A wire feeding assembly for transporting a wire to a winding sleeve is provided on the mounting frame. The mounting frame is provided with a control assembly and a wire pushing assembly. The wire pushing assembly is mounted on the control assembly. The control assembly drives the wire pushing assembly to slide along the length direction of the mounting shaft on the mounting frame. A component for pushing the wire to move along the length of the mounting shaft is provided on the wire pushing assembly, so that adjacent wires in the same layer are in close contact; the wire pushing assembly includes a sliding rod slidably connected to the control assembly, a wire pushing plate fixed to the control assembly, and an adjusting spring for pushing the wire pushing plate to move towards the direction of the adjacent wound wire. The sliding rod slides along the length direction of the mounting shaft. One end of the adjusting spring is fixed to the sliding rod, and the other end is fixed to the sliding rod. During wire winding, the wire pushing plate abuts against the side surface of the outermost wound wire, and the adjusting spring is in a stretched state.

[0007] By adopting the above technical solution, during the wire winding process, the wound wire will move along the length direction of the winding sleeve, and then the wire is evenly wound on the winding sleeve. After one layer of winding is completed, the wire needs to move in the reverse direction to wind the upper layer of wire until the entire winding sleeve presents a full-wound state. During the process of the wire moving along the length direction of the winding sleeve, the control assembly drives the wire pushing assembly to also move along the length direction of the winding sleeve. In addition, under the action of the adjusting spring, the wire pushing plate always abuts against the side surface of the outermost wire, and at the same time, the adjusting spring pushes the wire pushing plate to move along the axial direction of the winding sleeve, so that adjacent wires can be abutted more tightly, reducing the gap between adjacent wires.

[0008] Optionally, a lifting assembly is provided on the mounting frame. An adjusting assembly for driving the control assembly to move along the length direction of the mounting shaft is provided on the lifting assembly. The lifting assembly is used for driving the adjusting assembly to move in the vertical direction; the control assembly includes a mounting block provided on the adjusting assembly, a control shaft rotatably connected to the mounting block, a mounting sleeve slidably connected to the control shaft, and a connecting rod provided on the mounting sleeve. The sliding rod passes through the connecting rod and is slidably connected to the connecting rod along the length direction of the mounting shaft.

[0009] By adopting the above technical solution, the mounting shaft rotates, the angle of the connecting rod can be adjusted, and then the wire pushing plate on the connecting rod can better abut against the side surface of the wire. At the same time, when the number of turns of the wire wound on the winding sleeve increases, the connecting rod rotates away from the winding sleeve.

[0010] Optionally, the adjusting assembly includes an adjusting screw rod rotatably connected to the mounting frame and an adjusting motor fixed to the lifting assembly. The mounting block is sleeved on the adjusting screw rod and is threadedly connected to the adjusting screw rod. A limiting plate is fixedly installed on the lifting assembly. The mounting block slides along the length direction of the winding sleeve on the limiting plate.

[0011] By adopting the above technical solution, the adjusting motor is adjusted to drive the adjusting screw rod to rotate, and then the adjusting screw rod drives the mounting block to move. Thus, during the wire winding process, the pushing wire assembly and the wire move at the same speed.

[0012] Optionally, a pushing flat plate for abutting against the surface of the wire is fixedly mounted on the pushing wire plate.

[0013] By adopting the above technical solution, under the action of the pushing plate, when winding the wire, the wound wire can be pushed flat, and then the wound wire can be made more compact.

[0014] Optionally, an electric push rod is fixedly mounted on the mounting block, and one end of the electric push rod is fixed on the mounting sleeve.

[0015] By adopting the above technical solution, during wire winding, the electric push rod works to drive the pushing wire plate to reciprocate. During the process of the pushing wire plate moving close to the side of the wire, the wire can be tapped at intervals, so that the wire being wound and the adjacent already wound wire abut against each other, and thus the adjacent wires can be made to fit more closely.

[0016] Optionally, a first detecting member for detecting the position of the sliding rod is provided at the end of the sliding rod. When the position of the sliding rod is offset, the controller connected to the first detecting member adjusts the rotation speed of the control motor. The first detecting member is provided as a distance sensor.

[0017] By adopting the above technical solution, when the width of the wire becomes larger, the moving speed of the wire on the winding sleeve becomes faster. At this time, the pushing wire plate will be pushed to move away from the wound wire. At this time, the sliding rod will be offset. Then when the distance sensor detects a change in the distance, a signal is sent to the adjusting motor through the controller, so that the rotation speed of the adjusting motor increases, and thus the moving speed of the mounting block can become faster. Finally, under the action of the adjusting spring, the sliding rod is limited, thereby achieving the purpose of automatically adjusting the rotation speed of the adjusting motor.

[0018] Optionally, the connecting rod includes a fixed part and a rotating part. A rotating assembly for driving the rotating part to rotate towards the winding sleeve is provided on the fixed part. The fixed part is fixedly mounted on the mounting sleeve, and the rotating part is fixedly connected to the pushing wire plate.

[0019] By adopting the above technical solution, under the action of the rotating assembly, the pushing plate on the rotating part can better abut against the surface of the wound wire.

[0020] Optionally, the rotating assembly includes a rotating shaft fixedly connected to the fixed part and a torsion spring sleeved on the rotating shaft. The rotating part is rotatably connected to the rotating shaft. One end of the torsion spring is fixed on the rotating shaft, and the other end is fixed on the rotating part.

[0021] By adopting the above technical solution, the torsion spring pushes the rotating part to rotate downward, and then makes the pushing flat plate abut against the wire. Furthermore, during the wire winding process, the pushing flat plate can be applied to winding sleeves of different shapes.

[0022] Optionally, a fine-tuning component for fine-tuning the position of the wound wire is provided on the mounting block; the fine-tuning component includes a moving frame slidably connected to the mounting block, a fine-tuning spring fixed to the moving frame, a guide rod fixed to the moving frame, a moving block slidably connected to the guide rod, and a fine-tuning rubber wheel rotatably connected to the moving block. The moving block is sleeved on the guide rod. Two support springs for making the moving block in the middle position of the guide rod are arranged on both sides of the moving block. One end of the support spring is fixed to the moving frame, and the other end is fixed to the moving frame; the fine-tuning rubber wheel is provided with a first friction pattern and a second friction pattern. The first friction pattern and the second friction pattern have opposite helix directions and are arranged at intervals.

[0023] By adopting the above technical solution, under the action of the fine-tuning spring, the fine-tuning rubber wheel is pushed to abut against the wound wire. Then, during the rotation of the winding sleeve, the fine-tuning rubber wheel will be driven to rotate. During the rotation of the fine-tuning rubber wheel, the first friction pattern and the second friction pattern will push the wound wire to move towards the middle, and then the position of the wound wire can be fine-tuned to make the fitting effect of the wound wire better.

[0024] Optionally, a wire feeding component for feeding the wire onto the winding sleeve is provided on the mounting frame. The wire feeding component includes a moving plate slidably connected to the mounting frame, two rotating wheels rotatably connected to the moving plate, and two adjusting wheels slidably connected to the moving plate. The adjusting wheels and the rotating wheels are arranged in a staggered manner.

[0025] By adopting the above technical solution, when the number of turns of the wire wound on the winding sleeve increases, the tension of the wire will become larger. At this time, the two adjusting wheels move away from the rotating wheels, and the pressure on the wire becomes smaller, and then the purpose of adjusting the wire tension is achieved.

[0026] In summary, the present application has the following beneficial effects: 1. Under the action of the adjusting spring, the wire pushing plate always abuts against the side of the outermost wire, so that adjacent wires can abut more tightly, reducing the gap between adjacent wires.

[0027] 2. The electric push rod can drive the wire pushing plate to reciprocate. During the process of the wire pushing plate moving close to the side of the wire, the wire can be tapped at intervals, so that the wire being wound and the adjacent already wound wire abut against each other, and then the adjacent wires can be more closely attached.

Detailed implementation manners

[0037] The following Figures 1 - 8 further elaborates on the present application in detail.

[0038] An embodiment of the present application discloses a wire winding device for a transformer. Referring to Figures 1 to 3, A wire winding device for a transformer includes a mounting frame 01 and a mounting shaft 02 provided on the mounting frame 01. The winding sleeve on the transformer is sleeved on the mounting shaft 02. In this embodiment, the mounting shaft 02 is set as an expansion shaft, which can fix winding sleeves with different diameters on the mounting shaft 02; a lifting component 1 is provided on the mounting frame 01, and a wire pushing component 2 for pressing the position of the wire is provided on the lifting component 1. A wire feeding component 3 for transporting the wire onto the winding sleeve is also provided on the mounting frame 01. The height of the wire pushing component 2 can be adjusted through the lifting component 1; a control component 4 for driving the wire pushing component 2 to rotate or move is provided on the wire pushing component 2. Additionally, a fine-tuning component 5 for finely adjusting the position of the wire wound on the winding sleeve is provided on the control component 4.

[0039] Refer to Figures 1 to 3 , An adjusting component 6 is provided on the lifting component 1. The adjusting component 6 is used to adjust the positions of the wire pushing component 2, the control component 4, and the fine-tuning component 5, so that the wire pushing component 2 and the control component 4 can move along the length direction of the winding sleeve, and thus the wire is evenly wound on the winding sleeve.

[0040] Refer to Figures 1 to 3 , The lifting component 1 includes a lifting frame 11 slidably connected to the mounting frame 01 and a lifting cylinder 12 fixed to the lifting frame 11. The cylinder body of the lifting cylinder 12 is fixed to the mounting frame 01. The adjusting component 6, the wire pushing component 2, and the fine-tuning component 5 are all provided on the lifting frame 11. The position of the adjusting component 6 can be adjusted by the operation of the lifting cylinder 12.

[0041] Refer to Figures 1 to 3 , The adjusting component 6 includes an adjusting screw 61 rotatably connected to the mounting frame 01 and an adjusting motor 62 fixed to the lifting frame 11. The control component 4 is provided on the adjusting screw 61. In this embodiment, the adjusting motor 62 is set as a servo motor. The output shaft of the adjusting motor 62 is fixedly connected to the adjusting screw 61. By rotating the adjusting motor 62 to drive the adjusting screw 61 to rotate, the wire pushing component 2 and the control component 4 move along the length direction of the adjusting screw 61, and thus the positions of the wire pushing component 2 and the control component 4 can be adjusted.

[0042] Refer to Figures 2 to 4, the control component 4 includes a mounting block 41 sleeved on the adjusting screw 61, a control shaft 42 rotatably connected to the mounting block 41, a mounting sleeve 43 slidably connected to the control shaft 42, a connecting rod 44 arranged on the mounting sleeve 43, and an electric push rod 45 fixed on the mounting block 41. A limiting plate is arranged on the lifting frame 11. The mounting block 41 slides on the limiting plate along the length direction of the winding sleeve. The output end of the electric push rod 45 is fixed on the control shaft 42. In addition, the wire pushing component 2 is mounted on the connecting rod 44. When the electric push rod 45 works, the mounting sleeve 43 and the wire pushing component 2 arranged on the mounting sleeve 43 can move along the length direction of the control shaft 42.

[0043] Refer to Figures 4 to 8 , the fine-tuning component 5 is also arranged on the control component 4. The fine-tuning component 5 includes a moving frame 51 slidably connected to the mounting block 41, a fine-tuning spring 52 fixed on the moving frame 51, a guide rod 53 fixed on the moving frame 51, a moving block 54 slidably connected to the guide rod 53, and a fine-tuning rubber wheel 55 rotatably connected to the moving block 54. The moving block 54 is sleeved on the guide rod 53. Then, support springs 56 are arranged on both sides of the moving block 54. One end of each support spring 56 is fixed on the moving frame 51, and the other end is fixed on the moving frame 51. The two support springs 56 keep the moving block 54 at the middle position of the guide rod 53.

[0044] Refer to Figures 2 to 8 , the fine-tuning rubber wheel 55 is provided with a first friction pattern 551 and a second friction pattern 552. The helical directions of the first friction pattern 551 and the second friction pattern 552 are opposite, and the first friction pattern 551 and the second friction pattern 552 are arranged at intervals. The fine-tuning spring 52 pushes the fine-tuning rubber wheel 55 to abut against the wound wire. During the process of the mounting shaft 02 driving the winding sleeve to rotate, since the fine-tuning rubber wheel 55 abuts against the wire on the winding sleeve, when the wire being wound deviates, the first friction pattern 551 or the second friction pattern 552 on the fine-tuning rubber wheel 55 will push the wire towards the middle position of the fine-tuning rubber wheel 55. In the initial state, the wire pushing component 2 and the first friction pattern 551 are arranged on the same side, and the second friction pattern 552 will not push the wire to move. After one layer of wire is fully wound, it is necessary to move the moving block 54 in the reverse direction to wind the outer layer. At this time, the moving block 54 will move in the reverse direction, and the first friction pattern 551 will not push the wire to move when the moving block 54 moves in the reverse direction.

[0045] In this embodiment, two wire pushing assemblies 2 are provided. Both of the two wire pushing assemblies 2 are fixed on the mounting sleeve 43, and the structures of the two wire pushing assemblies 2 are the same. When one wire pushing assembly 2 abuts against the wire, the other wire pushing assembly 2 is separated from the wire. In addition, when one layer of wire is fully wound, the end face of the winding sleeve will abut against the surface of the fine-tuning rubber wheel 55, and then one fine-tuning spring 52 is stretched and the other fine-tuning spring 52 is compressed, so that the fine-tuning rubber wheel 55 can give way to the wire at the outermost edge, enabling the wound wire to abut against the end face of the winding sleeve. In addition, under the action of the two wire pushing assemblies 2, it is convenient to reverse the direction of the wound wire, and the purpose of compressing the wire after the reversal can still be achieved.

[0046] Referring to Figures 3 to 8 , the wire pushing assembly 2 includes a sliding rod 21 slidably mounted on the connecting rod 44, a wire pushing plate 22 fixed on the sliding rod 21, and a flat pushing plate 23 fixed on the wire pushing plate 22. The sliding direction of the sliding rod 21 is the same as the length direction of the control shaft 42. In addition, an adjusting spring 24 is sleeved on the sliding rod 21. One end of the adjusting spring 24 is fixed on the sliding rod 21 and the other end is fixed on the connecting rod 44. When winding the wire, the side of the wire to be wound will abut against the flat pushing plate 23, so that the flat pushing plate 23 pushes the wire being wound towards the direction close to the wire that has been wound, thereby reducing the distance between two adjacent wires. At this time, the adjusting spring 24 is in a stretched state. The wider the width of the wound wire, the longer the distance that the adjusting spring 24 is stretched. In addition, under the action of the flat pushing plate 23, the wire wound on the winding sleeve can be pushed to reduce the occurrence of wire bulges.

[0047] Referring to Figures 3 to 5 , a first detection member 03 is provided at the end of the sliding rod 21. The first detection member 03 is used to detect the position of the sliding rod 21 on the connecting rod 44, and then the controller connected to the first detection member 03 adjusts the rotation speed of the control motor. In this embodiment, the first detection member 03 is set as a distance sensor. When the width of the wound wire becomes larger, since the rotation speed of the adjusting motor 62 is not adjusted and the rotation speed of the adjusting motor 62 driving the adjusting screw 61 remains unchanged, the winding width of the wire on the winding sleeve increases relatively fast. At this time, the speed at which the adjusting screw 61 drives the wire pushing assembly 2 to move is relatively slow, and then the situation of wire stacking will occur. Since the rotation speed of the winding sleeve remains unchanged and the rotation speed of the adjusting motor 62 also remains unchanged, the wire wound on the winding sleeve will push the wire pushing plate 22 towards the direction of the wound coil. At this time, the adjusting spring 24 is further stretched, and then the first distance sensor detects that the distance becomes shorter. At this time, a signal is sent to the adjusting motor 62 through the controller to increase the rotation speed of the adjusting motor 62, so that the moving speed of the mounting block 41 becomes faster. At this time, the moving speed of the mounting block 41 is the same as the winding rate of the wire on the winding sleeve, and then the wire can be wound more evenly on the winding sleeve.

[0048] When the wound wire becomes narrower, the moving speed of the wire on the winding sleeve slows down along the length direction of the winding set. At this time, when the speed of the adjusting motor 62 remains unchanged, the distance between two adjacent wires will become smaller. Then, the adjusting spring 24 will pull the wire pushing plate 22 to move to the right. Subsequently, the distance sensor detects that the distance becomes larger. Under the action of the controller, the rotational speed of the adjusting motor 62 slows down, and the moving speed of the mounting block 41 slows down. At this time, the moving speed of the mounting block 41 is the same as the winding rate of the wire on the winding sleeve, and then the wire can be wound more evenly on the winding sleeve.

[0049] Since the electric push rod 45 is arranged on the mounting block 41 and the electric push rod 45 is connected to the mounting sleeve 43, and the mounting sleeve 43 slides on the control shaft 42. During the winding process, the electric push rod 45 can pull the mounting sleeve 43 to slide on the control shaft 42. During the sliding process, the mounting sleeve 43 will drive the wire pushing plate 22 to move towards the side of the outermost wire, and then strike the outermost wire. Through the intermittent knocking method, the abutting effect between two adjacent wires can be better.

[0050] Refer to Figures 3 to 8 , the connecting rod 44 includes a fixed part 441 and a rotating part 442. The fixed part 441 is provided with a rotating assembly 7 for driving the rotating part 442 to rotate. The fixed part 441 is fixedly installed on the mounting sleeve 43, and the rotating part 442 is fixedly connected to the wire pushing plate 22. Since the cross-section of the winding sleeve is not a regular circle, at this time, the rotating assembly 7 can push the pushing flat plate 23 to always abut against the surface of the wire, making the wire flattening effect of the pushing flat plate 23 better.

[0051] Refer to Figures 3 to 8 , the rotating assembly 7 includes a rotating shaft 71 fixedly connected to the fixed part 441 and a torsion spring 72 sleeved on the rotating shaft 71. The rotating part 442 is rotatably connected to the rotating shaft 71. One end of the torsion spring 72 is fixed on the rotating shaft 71, and the other end is fixed on the rotating part 442. Thus, under the action of the torsion spring 72, the rotating part 442 is pushed to rotate, making the pushing flat plate 23 abut against the surface of the wire, achieving the purpose of flattening the wire.

[0052] Look back at Figure 1 and Figure 2, the wire feeding assembly 3 includes a moving plate 31 slidably connected to the mounting bracket 01, two rotating wheels 32 rotatably connected to the moving plate 31, and two adjusting wheels 33 slidably connected to the moving plate 31. The adjusting wheels 33 and the rotating wheels 32 are arranged in a staggered manner. Then, when the number of turns of the wire wound around the winding sleeve increases, the tension of the wire will increase. At this time, the two adjusting wheels 33 move upward, reducing the pressure of the adjusting wheels 33 on the wire, thereby adjusting the tension of the wire. To facilitate the adjustment of the position of the wire feeding assembly 3, a wire feeding cylinder is provided on the mounting bracket 01. The wire feeding cylinder is fixedly connected to the moving plate 31, so as to drive the wire feeding assembly 3 to move along the length direction of the winding sleeve.

[0053] The implementation principle of a wire winding device for a transformer in an embodiment of the present application is as follows: When winding the wire, one end of the wire is fixed on the winding sleeve. The wire feeding assembly 3 clamps the wire, and then the winding sleeve is driven to rotate by the mounting shaft 02. At the same time, the adjusting assembly 6 drives the pushing flat plate 23 and the wire pushing plate 22 to move along the length direction of the adjusting screw 61. The fine-tuning rubber wheel 55 abuts against the surface of the wire being wound. The pushing flat plate 23 flattens the wire sleeved on the winding sleeve, and the wire pushing plate 22 squeezes the wound wire, thereby reducing the distance between adjacent wires. At the same time, the electric push rod 45 drives the wire pushing plate 22 to reciprocate, intermittently knocking the wound wire to further reduce the distance between adjacent two wires.

[0054] When the width of the wound wire becomes larger, since the rotation speed of the adjusting motor 62 is not adjusted, the rotation speed of the adjusting motor 62 driving the adjusting screw 61 remains unchanged. The winding speed of the wire on the winding sleeve increases relatively fast. At this time, the speed of the adjusting screw 61 driving the wire pushing assembly 2 to move is slower, and then the wound wire will stack up. Since the rotation speed of the winding sleeve remains unchanged and the rotation speed of the adjusting motor 62 also remains unchanged, the wire wound around the winding sleeve will push the wire pushing plate 22 towards the direction of the wound coil. At this time, the adjusting spring 24 is further stretched, and then the first distance sensor detects that the distance becomes shorter. At this time, a signal is sent to the adjusting motor 62 through the controller, increasing the rotation speed of the adjusting motor 62 and making the moving speed of the mounting block 41 faster. At this time, the moving speed of the mounting block 41 is the same as the winding speed of the wire on the winding sleeve, and then the wire can be wound more evenly on the winding sleeve.

[0055] When the wound wire becomes narrower, the moving speed of the wire on the winding sleeve along the length direction of the winding group slows down. At this time, when the speed of the adjusting motor 62 remains unchanged, the distance between two adjacent wires will become smaller. Then, the adjusting spring 24 will pull the wire pushing plate 22 to move to the right. At this time, the distance sensor detects that the distance becomes larger. Under the action of the controller, the rotation speed of the adjusting motor 62 slows down, and the moving speed of the mounting block 41 slows down. At this time, the moving speed of the mounting block 41 is the same as the winding rate of the wire on the winding sleeve, and then the wire can be wound more evenly on the winding sleeve.

[0056] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
