Description

Technical Field

[0001] This invention relates to a coil winding device for a transformer, and more specifically, to a coil winding device for a transformer in which multiple windings are simultaneously wound in a frame in a certain winding pattern, and a certain winding pattern of the windings is sensed, thereby preventing the phenomenon of rapid winding and disordered winding. Background Technology

[0002] Typically, most transformers are manufactured using a multi-layer (two-layer or multi-layer) structure, in which the coils of the structure, including primary and secondary windings according to magnetic coupling, are wound continuously on round or flat wire (made of rectangular copper or aluminum).

[0003] When using rectangular conductors (hereinafter referred to as "rectangular wires") for winding, the current in the conductor generates greater eddy current losses compared to that of a toroidal conductor (hereinafter referred to as "circular wires") of the same cross-sectional area. Furthermore, due to the rectangular shape, it is difficult to use a winding machine for winding, resulting in slow operating speed. The disadvantage is that it is relatively unfavorable for insulation.

[0004] Therefore, in order to overcome the disadvantages of winding with rectangular wire, winding with round wire can be considered. When winding with round wire, a semi-automatic winding machine can be used (for example, see Korean Utility Model Registration No. 20-0452392). Therefore, the working speed is fast, the quality difference between skilled workers and unskilled workers is small, and it has the advantages of easy wire feeding and small eddy current pointer.

[0005] However, if the cross-sectional area of ​​the circle is greater than (4Φ) will result in an increase in the number of vortex hands compared to the square line, and the normal use of the parallel line will lead to the existing disadvantages of the rectangular line.

[0006] Therefore, even if the cross-sectional area is greater than (4Φ) also requires the use of round wires and greatly reduces eddy currents. For example, the windings made of round wires can be separated and connected in parallel.

[0007] For example, the configuration implemented by the inventor based on experiments, namely using a winding machine to wind larger than... Rounding is performed on a large area of ​​(4Φ), such as... Figure 1 As shown.

[0008] like Figure 1As shown, in the case of round wire, in order to reduce eddy currents, the winding is divided into two parts along the vertical direction (the longitudinal direction of the spool or the core (hereinafter referred to as "core")) (1), with the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3) configured in parallel. Each parallel winding (2) (3) is wound in multiple layers (at least 2 layers) to ensure a predetermined number of windings, and the number of layers (2) (3) of each parallel winding and the layers of each parallel winding (materials with insulating properties, such as mica, synthetic resin film, etc. known in this technical field), the insulating element 5 can be insulated by intervention.

[0009] In particular, the insulating element 5 is placed between the layers of the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3) to perform the insulation function respectively. The upper insulating interlayer (5-1) and the lower insulating interlayer (5-2) and the upper insulation release prevention part (5-3) (5-4) are composed of a folded structure so that the round wire does not deviate. The upper insulating interlayer (5-1) and the lower insulation release prevention part (5-5) (5-6) are composed of each side of the upper insulating interlayer (5-1) and each side of the lower insulating interlayer (5-2) so that the round wire does not deviate.

[0010] However, since an insulator 5 is provided in both the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3), the length from the lower part of the iron core or spool (1) to the upper part of the iron core or spool (1) is increased, and the overall size of the transformer is also increased accordingly.

[0011] In addition, separate insulating components 5 are installed in the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3), and the insulating components (5) are also inserted between the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3), so that the upper multi-layer parallel winding (2) and the lower multi-layer parallel winding (3) cannot be wound at the same time.

[0012] Of course, it is possible to solve these problems using the technical configuration disclosed in registered patent 10-2659159, as one way to improve these problems.

[0013] However, in this registered patent 10-2659159, the size of the transformer can be greatly reduced, and a winding machine can be used to simultaneously wind multiple layers of parallel windings on the upper and lower sides, which greatly shortens the working time and improves productivity.

[0014] Furthermore, in registered patent 10-2659159, defects can be prevented by longitudinally deviating from both sides when the round wire is wound and stacked, because it includes an insulation breakage prevention component configured to prevent the round wire from deviating by supporting both sides of the assembly of the upper multi-layer parallel winding and the lower multi-layer parallel winding respectively.

[0015] However, in the registered patent 10-2659159, the two spools 510 and 520 loosen the round wire 250 or the spool 100 in the iron core during the winding process of the spool 510 and 520 through the rotational force in the iron core or the spool 100 due to rotational inertia, and the number of round wire 250 wound in the iron core or the spool 100 exceeds the number of spools 510 (520) that are loose.

[0016] Thus, if the looseness of the round wire 250 in the spool 510520 is large, the round wire 250 cannot be wound in the iron core or spool 100 in a regular and constant arrangement. Therefore, the winding speed must be delayed, and the round wire 250 is wound on the spool 100 in a disordered manner.

[0021] The problem that the invention aims to solve

[0022] To solve the above problems, the present invention aims to provide a coil winding device for transformers. This device can not only greatly reduce the size of the transformer, but also improve the winding speed and winding productivity because multiple parallel windings are wound on the spool. Most importantly, the windings in the spool can be wound in a certain pattern.

[0023] Methods for solving problems

[0024] To achieve the above objectives, the present invention is characterized by a transformer coil winding device, which comprises a spool portion consisting of a rotatable structure, such that the winding can be wound into a certain pattern. A winding pattern sensing part is installed on one side of the spool portion to sense a certain winding pattern. The winding part is installed on one side of the winding pattern sensing part so that the winding can be wound onto the spool portion.

[0025] The bobbin is a structure installed in which multiple windings rotate to allow them to wind in a certain pattern. A support plate is composed of support plates, and the bobbin core is located at the lower part of the bobbin. The support plate is installed in a rotatable structure within the support plate, but is connected to the upper bobbin core. The main mold rotates under the power of a drive motor. The main bobbin core is combined with fixed structures on both sides of the bobbin core, but is connected to the structure and engagement device of the main bobbin core, and consists of at least multiple spur gears to prevent deflection of the wound wire and enable the rotation of the bobbin core. It is installed in the vertical structure on both sides of the support plate, but is inserted into the bobbin. The support plate also includes a runaway component to prevent the umbrella from leaving the upper part. The unwinding part is rotatably installed in a structure on the upper part of the support plate to maintain a specified horizontal gap. A pair of unwinding rollers are used to loosen and rewind according to the rotation of the bobbin. The unwinding rollers are arranged between the unwinding rollers and fixed from the inside of the support plate to the center of the driven shaft installed in the rotating structure. The driven gear part rotates with an interlocking structure. The driven shaft is connected to the shaft and belt structure of the main coaxial cable and rotates by the power of the drive motor. The gear part that prevents the loosening roller from spinning is composed of a ratchet structure. The transformer coil winding device is exemplified by the example.

[0026] The winding pattern sensing part is a sliding part in the structure of the top of the fixed plate that slides left and right on the upper part of the fixed plate. The sliding part fixed to the top of the sliding part is combined with the sliding operation of the sliding part and operates simultaneously with the sliding operation of the sliding part to monitor the winding pattern in real time. The pattern adjustment part consists of at least multiple parts to induce winding to a certain winding pattern. The motor part is installed in the center part of the fixed plate base and is axially connected to the sliding part to provide the necessary power for the sliding operation of the sliding part. The sliding part has a predetermined thickness and consists of a structure for the left and right sliding of the slide plate component, a cam that induces the left and right sliding of the slide plate component while being axially connected to the motor part inside the slide plate component, and a cam that induces the left and right sliding during rotation operation. The structure extending on the left and right sides of the slide plate component, and the constraint guide grooves for the slider movement fixed to the upper part of the fixed plate for the slider to move horizontally in the left and right direction, constitute a configuration consisting of the extension of the slider movement in the left and right direction. This is a feature of an example.

[0027] Invention Effects

[0028] According to the present invention, the size of the transformer can be greatly reduced by using parallel windings, the winding speed and productivity can be improved, and defects such as deviation from the winding process can be prevented. In particular, the problem of disordered winding in the bobbin is significantly improved during the winding process, and the quality of the bobbin is improved due to winding in a certain pattern, and it also plays a role in preventing disordered winding.

[0057] A transformer coil winding device according to an embodiment of the present invention, for example referring to Figures 2 to 6 The accompanying drawings illustrate a preferred embodiment of the present invention in detail.

[0058] The coil winding device of the transformer of the present invention comprises a spool portion 1000 consisting of a rotatable structure, such that the winding 250 can be wound in a certain pattern. It is installed on an adjacent portion of the spool portion 1000 and wound around one side of the spool 1000 to induce a certain winding pattern of the winding 250. A winding pattern sensing portion 2000 is installed on an adjacent portion of the winding pattern sensing portion 2000 so that the winding pattern sensing portion 250 can be wound on the spool portion 1000. The winding 250 can be configured to include an unwinding portion 3000 to be unwound.

[0059] Winding 250 is an insulating sheathed toroidal conductor structure characterized by at least a plurality of windings wound in a certain pattern shape.

[0060] The spool section 1000 can be configured to include a support plate 1300, a main gearbox 1200, a spur gear 1100 (1100'), and anti-runaway components 1310 and 1320, as shown below. Figure 2 and Figure 3 As shown, for example Figure 2 and Figure 3 .

[0061] On the surface of the support plate 1300, the main motor 1200 can be mounted in a horizontally rotatable structure. This main motor 1200 is combined with the shaft of the drive motor 1210 mounted on either side of the support plate 1300, and can be rotated by the power provided by the drive motor 1210.

[0062] The spur gear 1100 (1100') is connected to a structure on both sides of the fixed linear shaft 100, wherein the winding 250 is wound and connected to the main gearbox 1200 on the support plate 1300 to the snap-fit ​​structure.

[0063] Thus, the spur gear 1100 (1100') rotates together with the main gear 1200, and the winding 250 can be wound around the winding tube 100. In this way, the spur gear 1100 (1100') can further perform the function of preventing the winding tube 100 from being wound during the winding process of the winding 250.

[0064] The anti-running rods 1310 and 1320 are fixed on both sides of the support plate 1300 and are installed vertically and inserted into both sides of the spool 100 so that the anti-running components 1310 and 1320 can perform functional actions to prevent the spool 100 from shifting on the support plate 1300.

[0065] That is, in the anti-vehicle departure components 1310 and 1320, the first component of the anti-vehicle departure component 1310 may be composed of fixed coupling structures located on both sides of the support plate 1300, and the second component of the anti-vehicle departure component 1320 is connected to a hinge structure that can be retracted from the first component. However, the upper part of the spool 100 may be provided with an insertion structure that can enter and exit from both sides of the spool 100.

[0066] In this way, the upper part of the second piece of the anti-drop component 1320 is inserted into the two parts of the spool 100, so that the spool 100 can be prevented from deviating from the support plate 1300 by the anti-drop components 1310 and 1320.

[0067] Furthermore, between the first and second components of the anti-disengagement components 1310 and 1320, there exists such as Figure 2 The connecting structure shown can be bent by a spring (T), thus allowing the second component to be folded. This bending is caused by the spring (T), and the elastic force provided by the spring (T) when the second component bends is due to the elastic force. The spring (T) is superior to torsion springs in application.

[0068] According to the folding of the second component, the winding of the bobbin 100 completed by the winding 250 can be removed from the upper end of the support plate 1300. The new bobbin 100 is installed on the top of the support plate 1300 by the return spring force of the second component in the retracted state, and rotates simultaneously with the rotation of the main winding machine 1200 and the take-up drum 250.

[0069] The spool 100 can be wound with a plurality of windings 250, and these windings 250 can be wound onto the spool 100 in a pattern by means of the attractiveness of the winding pattern portion 2000 and the unwinding portion 3000 described below.

[0070] The main power 1200 can be rotated by the power provided by the drive motor 1100 fixed on the side of the lower support plate of the spindle 100, and the spindle 100 also rotates and winds multiple windings 250 by the rotation of the main power 1200.

[0071] On the other hand, the spool 100 can rotate together with the rotation of the main force 1200 because the spur gear 1100 (1100') is coupled to the fixed structure on both sides of the spool 100 and connected to the main base sequence 1200 by a snap-fit ​​structure.

[0072] These spur gears 1100 (1100') are combined with at least a plurality of structures fixed to two parts of the spool 100 and connected to the main body 1200 and the meshing structure, so that the spool 100 can perform the function of rotating the spool 100 while preventing the winding deviation of the winding 250.

[0073] On the other hand, the winding pattern sensing unit 2400 is composed of a sliding part that slides left and right from the top of the fixed plate 2500 to the upper part of the support plate 2600. Such a sliding part has a predetermined thickness and can be configured with a sliding plate member 2400 that slides left and right.

[0074] The sliding plate component 2400 forms a perforation 2410 through the central portion of the structure. Such perforation 2410 extends vertically from both sides of the arc 2420. The curvature line 2420 extends to both sides of the arc 2420 and is formed vertically on the left and right sides. The structure includes an extension 2440 forming a horizontal straight line.

[0075] Furthermore, the interior of the porous 2410 has an eccentric structure, consisting of a cam 2450 installed in a rotatable structure. The cam 2450 is fixed to the lower part of the fixed plate 2500 together with the shaft of the motor unit 2520 installed in the structure below the fixed plate 2500, and rotates to induce the slicing component 2400 to slide left and right.

[0076] The telescopic platform 2440 is fixed to both sides of the upper part of the fixed plate 2500 by the constraint guide groove 2510, thereby enabling horizontal linear movement in the left and right directions.

[0077] Cam 2450 is a plate cam structure, that is, a structure with triangular vertices. The three sides of the triangle vertices that are connected to each other can be composed of convex parts with outward convex rounded corners.

[0078] Since the cam 2450 is formed with an eccentric axial structure that rotates relative to the vertex position, during the rotation of the cam 2450, the protrusion can rotate frictionlessly in the curvature line 2420, the vertex generates friction with the vertical line 2430, and during the rotation, the slide member 2400 is pushed to the left or right.

[0079] Thus, the slide member 2400 can slide to the left or right, and the extension portion 2440 extending to both sides of the slide member 2400 can operate in a straight line through the constraint guide groove 2510 without swinging up and down.

[0080] Accordingly, the pattern adjustment unit 2100 fixed on the top of the block 2300 on the top of the slide plate 2400 slides and adjusts according to the winding image data of the winding 250 provided by the vision camera 2200, so as to monitor the winding pattern of the winding 250 in real time, and the winding 250 can induce a certain winding pattern.

[0081] The pattern adjustment section 2100 consists of at least a plurality of windings 250 located at the top of the windings, and the winding pattern of the windings 250 is induced to wind in a certain form by means of interference.

[0082] On the other hand, the unwinding section 3000 may be composed of a configuration including a pair of unwinding rollers 3100, 3300 and a long-term fisherman 3200.

[0083] A pair of loosening rollers 3100 and 3300 can be rotatably mounted in a structure on the upper part of the support plate with a certain horizontal distance, that is, rotatably mounted in the fixed coupling part 3410 towards the center part of the driven shaft 3400, and the drive retrieval part 3200, which is arranged between the pair of unwinding rollers 3100 and 3300, is mounted in the interlocking structure.

[0084] In other words, such as Figure 6 As shown, the driven motor unit 3200 is composed of an interlocking structure with the gear unit 3410 so that a pair of loosening rollers 3100, 3300 can rotate on the upper air support plate.

[0085] In this way, a pair of unwinding rollers 3100 and 3300 rotate, so that the winding 250 can be wound onto the winding tube 100 at the same time. During the process of winding the winding 250 onto the winding tube 100, the pattern control unit 2100 monitors the winding pattern of the winding 250 in real time and can induce the winding 250 to be wound in a certain pattern.

[0086] The driven shaft 3400 can be rotated by the shaft of the driving force 1200 through the power of the drive motor 1210 and the belt structure, and can prevent the unwinding roller 3100 from rotating in the gear, so that the gear part 3410 can be configured with a ratchet gear structure.

[0087] The present invention is not limited to the foregoing embodiments and drawings. It will be apparent to those skilled in the art that various substitutions, modifications, conversions and variations can be made within the scope of the technical concept of the present invention.
