Description

[0001] The invention belongs to the technical field of transformer assembly, and in particular relates to an electronic transformer winding device. Background Art

[0002] An electronic transformer is a small power transformer that uses the principle of electromagnetic induction to convert voltage and current. It is usually composed of two major parts: an iron core and a winding (coil). It can stably output the required voltage and provide a stable power supply for circuits and equipment. The winding process of an electronic transformer is to tightly and orderly wind wires of specific specifications and quantities around the coil skeleton according to a predetermined number of turns and layers, ensuring that the pins are handled correctly and the skeleton is intact, thereby forming the electromagnetic induction part of the transformer. This process is crucial to the performance of the transformer.

[0003] The winding process of electronic transformers is usually semi-automatic. The skeleton of the electronic transformer is placed on a rotatable shaft. The enameled wire is manually pulled around the skeleton and driven to rotate. The enameled wire is wound around the skeleton. Due to the limitations of the winding device, the current winding process includes two main steps. The first step is to wind the enameled wire on the skeleton. After each layer of coil is wound, the enameled wire needs to be cut and the joint part is placed on the preset notch of the skeleton. The second step is to wrap a layer of insulating tape around the outer layer of the wound coil, and then repeat the above two steps until the winding is completed according to the specified number of turns.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection.

[0020] In the description of the embodiments, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, an electronic transformer winding device is provided in an embodiment of the present invention, which aims to simplify the steps of the electronic transformer winding process and speed up the winding speed. The device mainly includes a workbench 10, a drive shaft 20, a first winding unit 30, a wire drum 40 and a transmission box 70.

[0022] Among them, the workbench 10 is constructed as a plate body with an "L"-shaped cross-section. The workbench 10 includes a vertically arranged mounting plate. The drive shaft 20 is vertically arranged on the mounting plate and is rotatably connected to the mounting plate. The end of the drive shaft 20 is provided with a clamping part matching the inner diameter of the transformer skeleton 001, so that the end of the drive shaft 20 can be clamped on the transformer skeleton 001.

[0023] Furthermore, the first winding unit 30 is vertically arranged on the mounting plate, the wire drum 40 is rotatably installed at the end of the first winding unit 30, the transmission box 70 is arranged on the back side of the mounting plate, and a first driving motor 71 for driving the driving shaft 20 to rotate is fixedly provided in the transmission box 70 to drive the driving shaft 20 to rotate. The first winding unit 30 includes a first winding rod 301 and a second winding rod 302, and the wire drum 40 includes a first wire drum 41 and a second wire drum 42. The first wire drum 41 is rotatably installed at the output end of the first winding rod 301, and the second wire drum 42 is rotatably installed at the output end of the second winding rod 302.

[0024] When the driving shaft 20 drives the transformer skeleton 001 to rotate, the first wire on the first wire drum 41 and the second wire on the second wire drum 42 are successively wound around the outside of the transformer skeleton 001, wherein the first wire is set as the first enameled wire, and the second wire is set as the first insulating tape. During the winding process, the first enameled wire is first wound from the first end of the transformer skeleton 001 to the second end. After the first enameled wire is wound a certain number of times, the first insulating tape is wound around the outside of the first enameled wire from the first end, and replaces the existing insulating tape to form an insulating layer, wherein the width of the first insulating tape is slightly larger than the diameter of the first enameled wire. The first enameled wire is compactly wound during the winding process, and the first insulating tape is partially overlapped and wound around the outside of the first enameled wire during the winding process.

[0025] In this way, during the single-layer winding process of the enameled wire, the winding of one layer of coil and one layer of insulation can be completed, and the winding steps that are currently performed in two steps can be completed in one step, simplifying the winding steps.

[0026] Furthermore, in order to enable the winding process of the outer first insulating tape to follow the winding process of the inner first enameled wire, and to maintain a set spacing between the two during winding, the first winding rod 301 is configured to follow the winding process of the first wire, drive the first wire drum 41 to move linearly in the axial direction, so that the first wire is wound close to each other on the outside of the transformer skeleton 001, that is, to ensure that the first enameled wire is wound in a compact manner, and the second winding rod 302 is configured to drive the second wire drum 42 to move at the same speed as the first wire drum 41, that is, during the winding process of the first enameled wire, the first insulating tape is synchronously wound on the outside of the first enameled wire at a certain distance from the winding point of the first enameled wire, so that the first winding unit 30 can synchronously form a layer of coil and insulation layer during the winding process.

[0027] In some embodiments, when winding the wires in the same layer, after the first wire (i.e., the first enameled wire) is wound axially for a set length, the second wire (i.e., the first insulating tape) begins to be wound, wherein the set length is greater than the axial length of the wire reel 40, so that there will be no interference between the first enameled wire and the first insulating tape during the winding process. When the winding of the inner layer of the first enameled wire is completed, it is necessary to stop the winding, cut off the first enameled wire, and then continue to wind the first insulating tape around the coil formed by the first enameled wire until the entire coil is completely covered. Then, the first insulating tape is cut off, and the first enameled wire and the first insulating tape are rewound on the outer layer based on the formed coil until a coil with a set number of turns is wound around the transformer skeleton 001.

[0028] In order to further increase the speed of winding on the outside of the transformer skeleton 001, multiple first winding units 30 are arranged around the axis of the drive shaft 20, each first winding unit 30 includes a first winding rod 301 and a second winding rod 302, and each first winding rod 301 and the second winding rod 302 are installed with a first wire drum 41 and a second wire drum 42.

[0029] like Figure 5 As shown, each first winding unit 30 is used to wind a single layer of wire on the outside of the transformer skeleton 001. After the first winding unit 30 located in the inner layer is axially wound for a set length, the first winding unit 30 located in the outer layer starts to wind, wherein the set length is greater than the axial length of the wire drum 40. Multiple first winding units 30 are wound layer by layer from the inside to the outside. In this way, multiple layers of coils can be wound on the transformer skeleton 001 at the same time. During the winding process, the winding area presents a stepped distribution structure from the inside to the outside, and the winding is wound layer by layer from the inside to the outside. After each layer is formed, it is necessary to stop and cut the first enameled wire and the first insulating tape, and then rotate again to complete the winding of the outer coil and the insulating layer.

[0030] In some embodiments, the number of wire layers wound around the outside of the transformer skeleton 001 is a multiple of the number of first winding units 30, and the number of first winding units 30 is ≥1. For example, when the number of coil layers designed on the outside of the transformer skeleton 001 is six, the number of first winding units 30 can be set to two, three or six. When the number of first winding units 30 is two, two layers of coils are formed each time the winding is performed, and the winding needs to be repeated three times to form a six-layer coil. When the number of first winding units 30 is three, three layers of coils are formed each time the winding is performed, and the winding needs to be repeated twice to form a six-layer coil. When the number of first winding units 30 is six, it only needs to be wound once to form a six-layer coil.

[0031] In this way, the multi-layer winding process is carried out simultaneously, which can greatly increase the winding speed, especially for the winding of some transformers with long axial length and thin wire diameter, which can increase the winding speed exponentially.

[0032] like Figure 4 As shown, in some embodiments, the first winding rod 301 and the second winding rod 302 each include a linear telescopic rod 31, a transmission 32 and a driver 33. The transmission 32 is fixed to the mounting plate, the linear telescopic rod 31 and the driver 33 are both mounted on the transmission 32, and the linear telescopic rod 31 is provided with a retractable movable shaft. The driver 33 is used to drive the movable shaft to move linearly along the axis of the linear telescopic rod 31, and the wire drum 40 is rotatably mounted on the end of the movable shaft. During use, the driver 33 can drive the linear telescopic rod 31 to perform telescopic movement through the transmission 32. It adopts a high-precision servo-driven linear actuator, so that the axial position of each wire drum 40 can be accurately controlled to ensure that the wires do not interfere with each other.

[0033] During the winding process of the transformer, enameled wires of different wire diameters need to be wound according to different needs. Usually, the outer enameled wire used for the control circuit has a relatively thin wire diameter. However, when the enameled wires of thick and thin wire diameters are wound using the first winding unit 30 at the same time, the axial winding speeds are inconsistent. In order to ensure that the axial speeds of the enameled wires of different wire diameters are consistent during the winding process.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the device also includes a turntable 50, which is rotatably mounted on the mounting plate and coaxially distributed with the drive shaft 20. A second winding unit 60 is fixedly mounted on the turntable 50. The second winding unit 60 includes a third winding rod 601 and a fourth winding rod 602. The first wire drum 41 is rotatably mounted at the output end of the third winding rod 601, and the second wire drum 42 is rotatably mounted at the output end of the fourth winding rod 602.

[0035] Among them, the third wire is wound on the first wire reel 41 installed on the third winding rod 601, and the fourth wire is wound on the second wire reel 42 installed on the fourth winding rod 602. The third wire is set as the second enameled wire, and the fourth wire is set as the second insulating tape. The diameter of the second enameled wire is smaller than the diameter of the first enameled wire, and the width of the second insulating tape is smaller than the width of the first insulating tape.

[0036] When the rotating disk 50 drives the third winding rod 601 and the fourth winding rod 602 to rotate, the third wire and the fourth wire (the second insulating tape) are successively wound around the outer side of the outermost second wire. The third winding rod 601 is configured to follow the winding process of the third wire and drive the first wire drum 41 to move linearly along the axial direction, so that the third wire is wound around the outer side of the second wire in close contact with each other. The fourth winding rod 602 is configured to drive the second wire drum 42 to move at the same speed as the first wire drum 41. The winding speed of the third wire is greater than the winding speed of the first wire, so that the winding lengths of the first wire and the third wire in the axial direction are consistent within a unit time.

[0037] In some embodiments, a turntable 50 extends into one side of a transmission box 70 and is fixedly provided with a gear ring 51, and a second drive motor 72 for driving the gear ring 51 to rotate is fixedly provided in the transmission box 70. In this way, compared with the winding speed of the first winding unit 30 on the outside of the transformer skeleton 001 when the drive shaft 20 rotates, the turntable 50 drives the second winding unit 60 to rotate on the outer periphery of the drive shaft 20, so that the second winding unit 60 has a faster winding speed on the outside of the transformer skeleton 001. The rotation speed of the turntable 50 can be adjusted according to the wire diameter difference between the third wire (second enameled wire) and the first wire (first enameled wire), so that the winding lengths of the first wire and the third wire in the axial direction are consistent per unit time, thereby ensuring that the winding work of each layer can be carried out synchronously during the winding process.

[0038] Furthermore, a plurality of second winding units 60 are arranged around the axis of the driving shaft 20, each of the second winding units 60 comprises a third winding rod 601 and a fourth winding rod 602, and each of the third winding rod 601 and the fourth winding rod 602 is mounted with a first wire drum 41 and a second wire drum 42; Among them, each second winding unit 60 is respectively used for the second wire wound by the first winding unit 30 and the outer winding wire. After the second winding unit 60 located in the inner layer is axially wound for a set length, the second winding unit 60 located in the outer layer starts to wind, wherein the set length is greater than the axial length of the wire drum 40, and multiple second winding units 60 are wound layer by layer from the inside to the outside.

[0039] In this way, when there are more than two second enameled wires with the same wire diameter, there are at least two second winding units 60 on the corresponding turntable 50. Similar to the distribution of the multiple first winding units 30, the multiple second winding units 60 also wind the second enameled wire layer by layer from the inner layer to the outer layer in a stepped manner. It should be understood that when there are three wire diameters of the enameled wire, it is necessary to set a rotatable disk on the inner side or outer layer of the turntable 50 to wind the wire at different speeds to achieve a synchronous winding effect, which will not be repeated here.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0041] The above description of the implementation mode is not restrictive. The figure shown in the drawings is only one of the implementation modes, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the scope of protection.
