Description

Technical Field

[0001] This invention relates to a transformer, a transformer coil winding device, and a winding method. Background Technology

[0002] A transformer is a device that converts supplied electricity into the voltage required for the operation of the equipment to which the electricity is applied. In recent years, as electronic devices such as display devices have become increasingly miniaturized and thin-film, the transformers installed in these electronic devices have also tended to be miniaturized and thin-film.

[0003] With the miniaturization and thin-film construction of transformers (especially transformer spools), it may be difficult to ensure the insulation distance between coils or between coils and the core required for stable voltage conversion operations. Furthermore, when a transformer is mounted on a substrate of equipment including the transformer, its miniaturization and thin-film construction may place excessive loads on the transformer terminals electrically connected to the substrate. Additionally, adjusting the spacing between the transformer and the substrate may be necessary when mounting the transformer on the substrate.

[0004] To meet these diverse or specialized needs, transformers can be formed in various structures. Therefore, there is a need to develop a winding device and method that can wind the coil in a manner most suitable for the transformer structure.

[0047] Specific embodiments of the present invention are described below with reference to the accompanying drawings. The detailed description provided below is intended to aid in a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, this is merely exemplary, and the present invention is not limited thereto.

[0048] In describing embodiments of the present invention, detailed descriptions of known technologies related to the invention will be omitted where such descriptions are likely to obscure the core of the invention. Furthermore, several terms described below are defined in consideration of their function in the invention and may vary depending on the purpose or convention of the user or operator. Therefore, they should be defined based on the context throughout this specification. The terms used in the detailed description are for describing embodiments of the invention only and are not intended to be limiting. Singular expressions include plural expressions unless otherwise expressly intended. In this description, expressions such as "comprising" or "equipped" are used to refer to certain features, numbers, steps, operations, factors, parts or combinations thereof, and shall not be construed as excluding the presence or possibility of one or more other features, numbers, steps, operations, factors, parts or combinations thereof other than those described.

[0049] On the other hand, directional terms such as upper side, lower side, one side, and the other side are used in association with the configuration directions in the accompanying drawings. Components of embodiments of the present invention can be positioned in various configuration directions; therefore, directional terms are used for illustrative purposes only and are not intended to limit them.

[0050] Furthermore, terms such as "first" and "second" can be used to describe various components, but the components should not be limited to these terms. These terms can be used to distinguish one component from others. For example, without exceeding the scope of this invention, a first component can be named a second component, and similarly, a second component can be named a first component.

[0051] Figure 1 This is a diagram illustrating a winding apparatus according to an embodiment of the present invention. Figure 2 This is a diagram illustrating a drive clamp according to an embodiment of the present invention. Figure 3 This is a diagram illustrating a guide clamp according to an embodiment of the present invention.

[0052] refer to Figures 1 to 3 The winding device 100 according to an embodiment of the present invention may include a drive clamp 120, a guide clamp 140, and a supply nozzle 160.

[0053] The drive clamp 120 rotates synchronously with the connected winding shaft (not shown). For example... Figure 2 As shown, the drive body 122 of the drive clamp 120 can be configured as a cylindrical tube open at one end. However, it is not limited to this. The drive clamp 120 can be configured as a square column or a shape closed at both ends.

[0054] The winding shaft may be located within the housing 110. The interior or exterior of the housing 110 may further include a control module (not shown) for controlling the operation of the winding apparatus 100. Additionally, although not shown, the interior or exterior of the housing may include components typically provided in a winding apparatus, such as a winding motor for rotating the winding shaft, a tachometer for counting and displaying the number of turns, and a tensioner for transmitting tension to the wound coil.

[0055] The winding device 100 according to embodiments of the present invention can operate in at least one of manual, automatic, or semi-automatic modes. The control module may include control logic corresponding to the operating modes of the winding device 100 according to embodiments of the present invention. Alternatively, the control module may be configured in a system including the winding device 100 but not the winding device 100, and may control the winding operation of the winding device 100 via wired communication or short-range wireless communication.

[0056] The guide fixture 140 includes a coupling unit 142 and a guide body 144. The coupling unit 142 is shaped to correspond to the drive fixture 120, thereby coupling with the drive fixture 120. When the drive body 122 of the drive fixture 120 is configured as follows... Figure 2 When the cylindrical or tubular shape is shown, such as Figure 3 As shown, the connecting unit 142 can be configured as a cylinder that can be inserted into one end of the drive clamp 120.

[0057] By equipping the coupling unit 142 with a shape corresponding to the drive clamp 120 or the drive body 122, the robustness of the coupling unit 142 and the drive clamp 120 can be improved. Alternatively, the drive clamp 120 may further include a fixing port 124 penetrating the drive body 122. With the coupling unit 142 inserted into the drive clamp 120, the connection between the coupling unit 142 and the drive clamp 120 can be further secured by fastening a fastener (not shown) to the fixing port 124.

[0058] In addition, the length of the connecting unit 142 may vary depending on the winding device 100 on which it is installed.

[0059] The guide body 144 is connected to the coupling unit 142. Thus, when the winding shaft rotates, the drive clamp 120 connected to the winding shaft rotates, and due to the rotation of the drive clamp 120, the coupling unit 142 of the guide clamp 140 connected to the drive clamp 120 and the guide body 144 connected to the coupling unit 142 rotate.

[0060] The guide body 144 is configured with a shape in which the diameter expands from one end to the other end in the direction of the winding axis. When the end into which the coupling unit 142 is inserted into the drive clamp 120 is referred to as one end, and the end coupled with the guide body 144 is referred to as the other end, the other end of the coupling unit 142 can be configured to fit against the center portion of a surface formed on one end of the guide body 144. That is, the other end of the guide body 144 can be formed in an open shape.

[0061] When the engagement unit 142 of the guide clamp 140 is inserted into and engaged with the drive clamp 120, the guide clamp 140 may further include a mounting unit 180 formed from a synapse on one side.

[0062] The coil supplied from the supply nozzle 160 is wound onto a transformer (not shown) mounted on the mounting unit 180 by being attached to the outer surface of the guide body 144. One end of the coil supplied from the supply nozzle 160 may be detached from the top of the guide body 144 or the other end may be positioned above the drive clamp 120.

[0063] Figure 4 This is an exploded perspective view of a transformer according to an embodiment of the present invention. Figure 5 This is a bottom perspective view of a transformer according to an embodiment of the present invention.

[0064] refer to Figure 4According to an embodiment of the present invention, the transformer 200 may include a first main body unit 220 and a second main body unit 240.

[0065] The first main body unit 220 may include a coil winding unit 222, a first connecting pin support unit 224, and a second connecting pin support unit 226.

[0066] A coil can be wound on the coil winding unit 222. The coil winding unit 222 may include a first base unit 222-2, a first winding body unit 222-4, and a first cover unit 222-6. The first base unit 222-2 is configured to connect the first connecting pin support unit 224 and the second connecting pin support unit 226 between the first connecting pin support unit 224 and the second connecting pin support unit 226. The first base unit 222-2 may be configured to be flat. The first winding body unit 222-4 may be configured to protrude downward from the bottom surface of the first base unit 222-2. A coil is wound on the outer peripheral surface of the first winding body unit 222-4. A core insertion hole H1 may be formed on the inner side of the first winding body unit 222-4, into which a core component (not shown) is inserted and received. The first cover unit 222-6 may be provided from the lower end of the first winding body unit 222-4 toward the outer side of the first winding body unit 222-4. In an exemplary embodiment, the first covering unit 222-6 may be configured parallel to the first base unit 222-2. That is, the first covering unit 222-6 may be configured as a plate extending horizontally from the lower end of the first winding body unit 222-4 toward the outside of the first winding body unit 222-4. Because the first covering unit 222-6 is configured from the lower end of the first winding body unit 222-4 toward the outside of the first winding body unit 222-4, the downward movement of the coil wound around the outer peripheral surface of the first winding body unit 222-4 is restricted by the first covering unit 222-6, thereby enabling winding between the first covering unit 222-6 and the first base unit 222-2.

[0067] The first connecting pin support unit 224 can be disposed on one side of the first base unit 222-2. The first connecting pin support unit 224 can be attached to one side of the first base unit 222-2 through its bottom surface, thereby extending to one side of the first base unit 222-2. At least one first connecting pin component 224-2 can be disposed at the outer end of the first connecting pin support unit 224 (i.e., the end spaced apart from the first base unit 222-2), and the coil wound on the coil winding unit 222 is connected to the first connecting pin component 224-2. The first connecting pin component 224-2 can be bent downward. The first substrate mounting unit 224-4 can be disposed at both ends of the outer end of the first connecting pin support unit 224. The ends of the first substrate mounting unit 224-4 can be positioned to be attached to the substrate when the transformer 200 is mounted on the substrate (not shown). The height of the transformer 200 mounted on the substrate (not shown) can be adjusted by changing the length of the first substrate mounting unit 224-4.

[0068] The second connecting pin support unit 226 can be provided on the other side of the first base unit 222-2. That is, the second connecting pin support unit 226 can be provided in the opposite direction to the first connecting pin support unit 224. The connection structure between the second connecting pin support unit 226 and the first base unit 222-2 can be the same as that of the first connecting pin support unit 224. At least one second connecting pin component 226-2 can be provided at the outer end of the second connecting pin support unit 226 (i.e., the end separated from the first base unit 222-2), and the coil wound around the second main body unit 240 is connected to the second connecting pin component 226-2. The second connecting pin component 226-2 can be bent downwards. The second substrate mounting unit 226-4 can protrude downwards at both ends of the outer end of the second connecting pin support unit 226. The ends of the second substrate mounting unit 226-4 can be mounted on a substrate (not shown). By changing the length of the second substrate mounting unit 226-4, the height of the transformer 200 mounted on the substrate (not shown) can be adjusted.

[0069] Since the first connecting pin support unit 224 and the second connecting pin support unit 226 form the first substrate mounting unit 224-4 and the second substrate mounting unit 226-4 at their respective ends, the load applied to the first connecting pin component 224-2 and the second connecting pin component 226-2 when the transformer 200 is mounted on the substrate (not shown) can be distributed.

[0070] The inner side of the second main body unit 240 may be provided with a receiving hole H2, into which the coil winding unit 222 of the first main body unit 220 is inserted and received. The receiving hole H2 may be configured to penetrate the second main body unit 240 in the height direction. The receiving hole H2 may be configured in the length direction of the second main body unit 240. When the first main body unit 220 is lowered while it is positioned above the second main body unit 240, the coil winding unit 222 can be inserted into the receiving hole H2 and received. That is, the first main body unit 220 and the second main body unit 240 are combined in a vertical direction. In this case, the coil winding unit 222 becomes a shape surrounded by the second main body unit 240. As a result, the coil wound on the coil winding unit 222 is protected from the influence of the external environment by the second main body unit 240.

[0071] The second main body unit 240 may include a second base unit 242, a second winding main body unit 244, and a second covering unit 246.

[0072] When the coil winding unit 222 is inserted into the receiving hole H2, the second base unit 242 can be mounted on the bottom surface of the first connecting pin support unit 224 and the second connecting pin support unit 226. The second base unit 242 can be positioned outside the first base unit 222-2 at a height corresponding to the first base unit 222-2. The second winding body unit 244 can be positioned protruding downwards from the bottom surface of the second base unit 242. A coil can be wound around the outer peripheral surface of the second winding body unit 244. The receiving hole H2 can be provided on the inner side of the second winding body unit 244, into which the coil winding unit 222 is inserted and received. The first body unit 220 and the second body unit 240 can be made of insulating materials, but of different materials. Compared to the first body unit 200, the second body unit 240 can be made of a softer material. That is, the first body unit 200 can be made of a harder material than the second body unit 240. The second covering unit 246 can be disposed from the lower end of the second winding main unit 244 toward the outside of the second winding main unit 244. In an exemplary embodiment, the second covering unit 246 can be disposed parallel to the second base unit 242. That is, the second covering unit 246 can be disposed as a plate extending horizontally from the lower end of the second winding main unit 244 toward the outside of the second winding main unit 244. Because the second covering unit 246 is disposed from the lower end of the second winding main unit 244 toward the outside of the second winding main unit 244, the downward movement of the coil wound around the outer peripheral surface of the second winding main unit 244 is restricted by the second covering unit 246, thereby enabling winding between the second covering unit 246 and the second base unit 242.

[0073] Figure 6 This is a diagram illustrating the second main body unit according to an embodiment of the present invention.

[0074] refer to Figure 6 The second main body unit 240 may be further equipped with an insulating block BL. The insulating block BL is used to ensure the insulation distance between the coil wound around the second main body unit 240 and the coil connected by the first connecting pin support unit 224. The insulating block BL may be arranged between the first connecting pin member 224-2 and the coil wound around the second main body unit 240. The insulating block BL may be provided with the second main body unit 240 protruding downward from one side of the second base unit 242 (corresponding to the side of the first connecting pin support unit 224). In this case, one side of the second base unit 242 may be configured to extend further outward, or additional structures may be added to one side of the second base unit 242.

[0075] As described above, the transformer 200 according to embodiments of the present invention can be configured to meet the requirements of miniaturization and thin-film technology while also performing a stable function. However, it is not limited to this. The second connecting pin support unit 226 may also be provided in the second main body unit 240 as needed. Although the transformer 200 has various structures as needed, the winding device 100 according to embodiments of the present invention can easily and effectively perform the winding operation. This will be described in further detail below.

[0076] Figure 7 This is a diagram showing the state of the transformer when it is installed in the winding device according to an embodiment of the present invention.

[0077] refer to Figure 5 and Figure 7 The transformer can be mounted on the mounting unit 180 of the winding device 100 according to an embodiment of the present invention, with its bottom surface facing upwards. That is, by aligning one end of the first substrate mounting unit 224-4 and the second substrate mounting unit 226-4 of the transformer 200 with the winding device 100, the core insertion hole H1 of the transformer 200 can be connected to the mounting unit 180, wherein said one end is the end spaced apart from the first connecting pin support unit 224 and the second connecting pin support unit 226. At this time, Figures 4 to 6 After the first main body unit 220 is wound by the winding device 100, the winding operation of the second main body unit 240 can be performed without any other process, so that the second main body unit 240 can be combined with the first main body unit 220.

[0078] Figure 8 This is a diagram illustrating the operation of winding a coil on a transformer equipped with a winding device according to an embodiment of the present invention.

[0079] refer to Figure 4 and Figure 8The winding operation of the first main body unit 200 of the transformer 200 can be performed first. The supply nozzle 160 can be positioned above the other end of the guide body 144 after detaching from it. However, the supply nozzle 160 can also be positioned above the guide body 144 between one end and the other end. The coil can exit from one end of the supply nozzle 160 and adhere to the outer surface of the guide body 144, and be wound around the first winding main body unit 222-4 of the first main body unit 220.

[0080] At this time, the winding operation can be performed without adjusting the position or angle of the supply nozzle 160, even though a first substrate mounting unit 224-4 and a second substrate mounting unit 2226-4 protruding on the first main body unit 220 are formed, by supplying the coil along the outer surface of the guide body 144, which is shaped as having a diameter that expands from one end to the other.

[0081] The transformer 200 is equipped with Figure 6 The same applies to the embodiments.

[0082] That is, even if any component is formed on a horizontally extending line on one or both sides of the first main unit 220 or the second main unit 240 due to miniaturization, thin-film design, or stability considerations, the winding apparatus 100 according to the embodiment of the present invention can easily and effectively perform the winding operation. Here, the horizontal direction can refer to a direction orthogonal to the bonding direction of the first main unit 220 and the second main unit 240 of the transformer 200.

[0083] Furthermore, according to the embodiment of the present invention, after the coil is wound into the first main body unit 220, the transformer 200 can be wound into the second main body unit 240 by combining the second main body unit 240 with the first main body unit 220 on which the coil is wound, without the need for additional processes such as replacing it with a drive fixture corresponding to the second main body unit 240.

[0084] Figure 9 This is a diagram illustrating the guide body according to an embodiment of the present invention.

[0085] refer to Figure 8 and Figure 9 As described above, the guide body 144 according to an embodiment of the present invention can be configured with a shape in which the diameter increases from one end X to the other end Y. That is, it can be formed in a continuous shape from one end X to the other end Y, and is configured such that the diameter DM1 of the end X on which the transformer 200 is mounted is larger than the diameter DM2 of the other end Y.

[0086] The length XY or inclination A of the guide body 144 from one end X to the other end Y can be set differently depending on the structure of the installed transformer 200. For example, the length XY or inclination A of the guide body 144 may correspond to the bending length of at least one end of the installed transformer 200. For example, the length XY of the guide body 144 may be proportional to the bending length of at least one end of the installed transformer 200. For example, the length XY of the guide body 144 may be formed to be longer than the bending length of at least one end of the installed transformer 200.

[0087] The bending length of one end of the transformer 200 can be the length of the first substrate mounting unit 224-4 and the second substrate mounting unit 226-4, or the bending length of the first connecting pin component 224-2 and the second connecting pin component 226-2. Alternatively, the bending length of one end of the transformer 200 can be the height of the insulating block BL (the bending length).

[0088] Alternatively, the length XY or inclination A of the guide body 144 from one end X to the other end Y can be set differently depending on the uniformity of coil winding required by the coil winding unit 222 and the second winding body unit 244. When the inclination A of the guide body 144 is less than or equal to a first standard value, relatively more tension should be applied to the coil supplied from the nozzle, but this can damage the coil and cause uneven coil winding. For example, the first standard value can be the angle formed by the line connecting the bent portion L of the first connecting pin component 224-2 and the bent portion K of the second connecting pin component 226-2 with the line connecting the bent portion L of the first connecting pin component 224-2 and the end N of the second connecting pin component 226-2.

[0089] Furthermore, the length XY or inclination A from one end X of the guide body 144 to the other end Y can be set in consideration of its relationship with the supply nozzle 160. For example, the length XY or inclination A of the guide body 144 can correspond to the distance between the two ends of the installed transformer 200 and the supply nozzle 160, or the angle formed between the two ends of the installed transformer 200 and the supply nozzle 160.

[0090] For example, the length XY of the guide body 144 can be formed with a length greater than or equal to the shortest distance DMP between the end M of the first connecting pin member 224-2 and the supply nozzle 160. Here, the shortest distance DMP refers to the straight-line distance between the end M of the first connecting pin member 224-2 and the end of the supply nozzle 160 of the supply coil when they are on the same line; that is, when the end of the supply nozzle 160 is located at a virtual point P on the same line as the virtual line extending from the end M of the first connecting pin member 224-2. Figure 8Unlike other components, when the end of the first substrate mounting unit 224-4 protrudes beyond the end M of the first connecting pin component 224-2, the shortest distance DMP to the supply nozzle 160 can be the distance between the end of the first substrate mounting unit 224-4 and the virtual point P.

[0091] Alternatively, the shape of the guide body 144 can be set with consideration of its installation state with the transformer 200. For example, the length XY or the inclination A from one end X to the other end Y of the guide body 144 can be set such that the shortest distance between the guide body 144 and the end of the first substrate mounting unit 224-4 of the installed transformer 200 or the end M of the first connecting pin member 224-2 is greater than or equal to the length (①) between the end of the first substrate mounting unit 224-4 and the end M of the first connecting pin member 224-2 plus the length of the coil diameter, or the length (②) between the end N of the first covering unit 222-6 and the end of the second connecting pin member 226-2 plus the length of the coil diameter. Figure 8 An example of the first covering unit 222-6 being formed in a flat plate shape is shown, but it is not limited thereto. When the two ends of the first covering unit 222-6 are bent to form, the content related to the length (②) between the end N of the first covering unit 222-6 and the second connecting pin member 226-2 can also be applied to the length between the bent portion O of the first covering unit 222-6 and the end N of the second connecting pin member 226-2. (In winding...) Figure 4 When the second main body unit 240 is in the same way, the second covering unit 246 with both ends bent is also in the same way.

[0092] Considering the above conditions, for example, the length XY of the guide body 144 can be about 5cm to 10cm, and the tilt angle A can be about 8 degrees to 20 degrees.

[0093] When the length XY or inclination A of the guide body 144 does not meet the above conditions, various problems may occur, such as the coil being damaged due to friction between the coil and the guide body 144 under tension, or the coil being detached from the guide clamp 140 and wound into the drive clamp 120.

[0094] The above description of the length XY or inclination A from one end X to the other Y of the guide body 144 also applies to its relationship with the second connecting pin component 226-2, but not with the first connecting pin component 224-2. Similarly, the above description of the length XY or inclination A from one end X to the other Y of the guide body 144 also applies to its relationship with the second substrate mounting unit 226-4, but not with the first substrate mounting unit 224-4.

[0095] As described above, the winding apparatus 100 according to an embodiment of the present invention is able to perform the winding operation effectively and accurately by being equipped with a guide body 144 having a size or shape optimized for the structure of the transformer 200 to be wound.

[0096] The above describes the winding apparatus 100 according to an embodiment of the present invention, in which the drive clamp 120 and the guide clamp 140 are respectively equipped as follows: Figure 2 and Figure 3 Examples of shapes are shown. However, this is not the only example.

[0097] Figure 10 This is a diagram illustrating a drive clamp and a guide clamp according to another embodiment of the present invention.

[0098] refer to Figure 10 ,and Figure 1 different, Figure 10 In the winding device 100, the drive clamp 120 can be configured as a cylinder, the inner periphery of the coupling unit 142 of the guide clamp 140 is the same as the diameter of the drive clamp 120, and its outer periphery is formed into a ring that fits against one end of the guide body 144.

[0099] Therefore, the drive clamp 120 can penetrate the engagement unit 142 and engage with the guide clamp 140. The outer peripheral surface of the drive clamp 120 can be further equipped with fixing protrusions 126 to fix the outer peripheral edge of the engagement unit 142.

[0100] exist Figure 10 In the example, the mounting unit 180 may be equipped at one closed end of the drive clamp 120.

[0101] The above description is merely an example of a winding apparatus 100 according to an embodiment of the present invention equipped with a pair of drive clamps 120 and guide clamps 140. However, it is not limited thereto.

[0102] Figure 11 This is a diagram illustrating a winding device according to another embodiment of the present invention. Figure 12 This is a diagram illustrating the operation of the supply nozzle according to an embodiment of the present invention.

[0103] refer to Figure 4 , Figure 11 as well as Figure 12 According to an embodiment of the present invention, the winding apparatus 100 can simultaneously wind a plurality of transformers 200 by being equipped with a plurality of pairs of drive clamps 120 and guide clamps 140. Additionally, a supply nozzle 160 can be individually equipped with a pair of drive clamps 120 and guide clamps 140.

[0104] Each supply nozzle 160 can be mounted to the nozzle position adjustment unit 190 via the nozzle connection component 192. For example... Figure 12As shown, the nozzle position adjustment unit 190 can move at a 90-degree angle toward the direction in which the transformer 200 is mounted. However, the nozzle position adjustment unit 190 may be difficult to move, for example, by equipping a winding shaft in the direction opposite to the direction in which the transformer 200 is mounted.

[0105] As described above, the winding apparatus 100 according to the embodiments of the present invention can easily and effectively perform the winding operation without adjusting the position or angle of the supply nozzle 160 and without being limited by the structure of the transformer 200. Figure 11 The winding device 100 can be a CNC winding device.

[0106] Furthermore, according to an embodiment of the present invention, the winding device 100 winds the coil after guiding it with the guide clamp 140, thus enabling the transformer 200 to be wound while the first connecting pin member 224-2 and the second connecting pin member 226-2 are in a bent state. Therefore, by reducing the interval between a pair of adjacent drive clamps 120 and guide clamps 140 of the winding device 100, the winding device 100, which is of limited size, can simultaneously perform winding operations on more transformers 200.

[0107] Furthermore, according to an embodiment of the present invention, the winding device 100 winds the transformer 200 while the first connecting pin component 224-2 and the second connecting pin component 226-2 are in a bent state, thereby improving the stability of the electrical connection state between the first connecting pin component 224-2, the second connecting pin component 226-2 and the coil. When the first connecting pin component 224-2 and the second connecting pin component 226-2 are wound in an unbent state due to the limited structure of the winding device, and the wound coil is bonded to the first connecting pin component 224-2 and the second connecting pin component 226-2 by welding, subsequent bending operations performed on the first connecting pin component 224-2 and the second connecting pin component 226-2 may reduce the firmness between the coil and the first connecting pin component 224-2 and the second connecting pin component 226-2. This reduced firmness between the coil and the first connecting pin component 224-2 and the second connecting pin component 226-2 may affect the electrical stability of the transformer 200.

[0108] Figure 13 and Figure 14 These are diagrams illustrating guide clamps according to another embodiment of the present invention.

[0109] refer to Figure 13 and Figure 14 According to an embodiment of the present invention, the cross-sectional shape of the guide body 144 of the guide clamp 140 can be adapted to correspond to the shape of the combinable transformer 200 (spool). Figure 4 The first and second main units are equipped with shapes.

[0110] Additionally, both ends (two cross-sections) of the guide body 144 of the guide clamp 140 can be equipped with a closed shape. However, at least one unloading groove 146 can be formed from the other end of the guide body 144 in one direction. After the winding operation in the transformer 200 is terminated, pressure is applied by inserting a protruding part (not shown) of the winding device into the unloading groove 146, such as... Figure 10 The transformer 200 is automatically separated from the guide clamp 140 in the CNC winding device. At this time, the unloading groove 146 can be configured as a shape that is open to the other end of the guide body 144 and closed to one end of the guide body 144 or a shape that extends through the guide body 144.

[0111] Figure 15 This is a flowchart illustrating a transformer winding method according to an embodiment of the present invention.

[0112] refer to Figure 1 , Figure 4 as well as Figure 15 The winding method 1500 for winding a coil onto a transformer 200 according to an embodiment of the present invention includes step S1520, in which a primary coil guided from a supply nozzle 160 via a guide clamp 140 is wound onto a first main body unit 220. Therefore, the winding method 1500 according to an embodiment of the present invention can perform a winding operation suitable for the structure of the transformer 200.

[0113] Furthermore, the winding method 1500 according to an embodiment of the present invention may further include steps S1540 and S1560, where S1540 involves attaching the second main body unit 240 to the first main body unit 200 to be wound, and S1560 involves winding the secondary coil guided from the supply nozzle 160 through the guide clamp 140 to the second main body unit 240. Therefore, the winding method 1500 according to an embodiment of the present invention requires no additional processes, thus improving process efficiency or production efficiency.

[0114] At this time, the winding step S1520 on the first main body unit 200 or the winding step S1540 on the second main body unit 240 can be performed while the first connecting pin component 224-2 and the second connecting pin component 226-2 are in a bent state. Therefore, the winding method 1500 according to the embodiment of the present invention allows the winding device 100 of a limited size to perform winding operations on more transformer devices 200 simultaneously.

[0115] Figure 15 The winding method 1500 is applicable to Figure 1 or Figure 11 Winding device 100, etc. Through Figure 15 The winding method 1500 is not limited to the transformer 200 being wound. Figure 4 .

[0116] The foregoing has described representative embodiments of the present invention in detail. However, those skilled in the art will understand that various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention is not limited to the embodiments described above, but is defined by the claims and their equivalents.
