Description

Technical Field

[0001] The invention belongs to the technical field of transformer production equipment, and in particular relates to a coil winding device for a new energy grid-connected machine transformer. Background Art

[0002] The new energy grid-connected transformer is a key device in the photovoltaic grid-connected power generation system. It is mainly used to convert the direct current generated by photovoltaic power generation into alternating current that matches the power grid and increase it to a voltage level suitable for long-distance transmission. When preparing the new energy grid-connected transformer, the transformer coil needs to be wound. During the winding process, different transformer coils need to have different numbers of winding layers.

[0003] For example, the patent document application number is 202211716836.2, which discloses a transformer coil winding device, including: a wire core roller, a tensioning box, a tensioning mechanism, a damping mechanism one and a damping mechanism two. During the coil winding process, the coil is arranged in layers along the radial direction of the wire core roller and is continuously wound. A tensioning mechanism, a damping mechanism one and a damping mechanism two are arranged in the path of the coil introduction wire core roller. The tensioning mechanism is used to tension and adjust the coil, which can ensure the tightness of the coil during radial continuous winding. The damping mechanism one and the damping mechanism two are used to increase the friction resistance of the guide coil, which can ensure the tightness of the coil during axial continuous winding, thereby meeting the tightness requirements of the coil against vibration and noise.

[0004] However, although the above-mentioned winding equipment can ensure the tightness of the coil during axial continuous winding, it can usually only wind a single coil. During mass production, the coil winding efficiency is affected, thereby reducing the production rate of the transformer.

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] The embodiments of the present invention provide a coil winding device for a new energy grid-connected machine transformer, as Figures 1-11As shown in the figure, it includes: a wire pay-off assembly 1, which is used to carry a plurality of coil reels to be wound and perform wire pay-off operations on the plurality of coil reels to be wound;

[0036] As Figures 2-3 shown in the figure, the wire pay-off assembly 1 includes a base 101, on which a plurality of wire pay-off rollers 102 for sleeving coil reels are rotatably connected. A bearing plate 103 for supporting the coil reel is sleeved on the outer wall of each wire pay-off roller 102. The lower end of the wire pay-off roller 102 passes through the base 101 and is fixed with a transmission gear 104. The transmission gears 104 on the plurality of wire pay-off rollers 102 are meshed with each other in pairs. A first motor 105 is installed at the lower end of one of the wire pay-off rollers 102, so that the first motor 105 drives the wire pay-off rollers 102 to rotate simultaneously through a plurality of meshed transmission gears 104, so as to perform wire pay-off operations on the coil reels on the wire pay-off rollers 102 at the same time.

[0037] A convex portion 106 is integrally formed on the outer wall of the upper end of the wire pay-off roller 102. A slot for inserting the convex portion 106 is provided on the core of the coil reel. Through the cooperation of the convex portion 106 and the slot, the coil reel can be stably connected to the wire pay-off roller 102, avoiding the phenomenon that the wire pay-off roller 102 idles due to the sliding between the coil reel and the wire pay-off roller 102 during the wire pay-off process.

[0038] A traction assembly 2 for traction of a plurality of coils paid off by the wire pay-off assembly 1, and the traction assembly 2 can adjust the traction height of the coils according to the coil winding height requirements;

[0039] As Figure 4 shown in the figure, the traction assembly 2 includes a bottom plate 21. A support plate 24 is installed on the upper surface of the bottom plate 21 through a lifting mechanism. A fixed seat 25 is fixed on the support plate 24. A pressing roller 210 is rotatably connected to the fixed seat 25. A plurality of upper pressing mechanisms are arranged side by side at the inner top of the fixed seat 25. The plurality of upper pressing mechanisms are connected to the fixed seat 25 through a height adjusting mechanism. The plurality of upper pressing mechanisms and the pressing roller 210 are located on the same horizontal plane. A wire passing groove for the coil to pass through is provided between the upper pressing mechanism and the pressing roller 210. The coil is passed through the wire passing groove and towed to the winding assembly 3 to comb and guide the paid-off coil, avoiding the phenomenon of the coil being messy and entangled during the coil winding process.

[0040] The upper pressing mechanism includes a U-shaped seat 28, and a upper pressing roller 29 is rotatably connected inside the U-shaped seat 28. A plurality of second limiting notches 212 are equidistantly formed on the outer wall of the upper pressing roller 29, and a plurality of first limiting notches 211 are equidistantly formed on the outer wall of the lower pressing roller 210. The first limiting notches 211 are correspondingly arranged with the second limiting notches 212 on the plurality of upper pressing rollers 29, and the first limiting notches 211 and the second limiting notches 212 are aligned. A wire threading hole is formed between the first limiting notch 211 and the second limiting notch 212. Through the plurality of wire threading holes, it is convenient to simultaneously traction multiple coils. By using the cooperation of the plurality of upper pressing rollers 29 and one lower pressing roller 210, when traction multiple coils, modular pressing with the lower pressing roller 210 can be carried out with the upper pressing roller 29 as a unit, so that the pressure between each upper pressing roller 29 area and the lower pressing roller 210 is kept uniform, avoiding the phenomenon that the middle part cannot be tightly pressed due to the longer length of the upper pressing roller 29 caused by a large number of traction coils, so as to affect the traction effect.

[0041] The height adjusting mechanism includes a lead screw 27 and two guide rods 213. One end of the lead screw 27 is rotatably connected to the middle of the U-shaped seat 28, and the other end of the lead screw 27 passes through the fixed seat 25 and is connected with an adjusting hand disc 26. And the lead screw 27 is threadedly connected with the fixed seat 25. The two guide rods 213 are fixed on the U-shaped seat 28 on both sides of the lead screw 27, and the upper ends of the guide rods 213 are slidably connected with the fixed seat 25. By rotating the lead screw 27 through the adjusting hand disc 26, the lead screw 27 drives the U-shaped seat 28 to move up or down by using the threaded cooperation with the fixed seat 25, so as to adjust the distance between the upper pressing roller 29 and the lower pressing roller 210. Through the arrangement of the guide rods 213, it is avoided that the U-shaped seat 28 rotates when the lead screw 27 rotates, so as to ensure that the U-shaped seat 28 can move in the horizontal direction.

[0042] The lifting mechanism includes a first electric push rod 22 and two telescopic rods 23. The two telescopic rods 23 are located on both sides of the first electric push rod 22. The lower ends of the first electric push rod 22 and the telescopic rods 23 are both fixed to the upper surface of the bottom plate 21, and the upper ends of the first electric push rod 22 and the telescopic rods 23 are both connected to the lower surface of the support plate 24. By driving the support plate 24, the upper pressing roller 29 and the lower pressing roller 210 to move up or down through the first electric push rod 22, the height of the wire threading hole is matched with the height of the winding assembly 3, so as to improve the convenience of use.

[0043] As Figures 5-6As shown, a winding assembly 3 for winding the coil pulled by the traction assembly 2, the winding assembly 3 includes a support seat 31, a protection box 32 is installed on the support seat 31, and a plurality of clamping mechanisms are installed above the protection box 32, each of the clamping mechanisms is composed of a second clamping member 34 capable of driving the transformer core to rotate and two symmetrically arranged first clamping members 33, and the second clamping member 34 is located between the two first clamping members 33, and a clamping space for fixing the transformer core is formed between the first clamping member 33 and the second clamping member 34, and the second clamping members 34 of the plurality of clamping mechanisms are all connected by a transmission mechanism 35, and the transmission mechanism 35 is driven by a second motor 36;

[0044] like Figure 7 As shown, the first clamping member 33 includes a vertical plate 3311 and a first magnetic plate 337, the vertical plate 3311 is rotatably connected to a connecting block 335, a sliding rod 331 is slidably inserted in the connecting block 335, one end of the sliding rod 331 is fixed with a limiting block 332, the other end of the sliding rod 331 passes through the connecting block 335 and is connected to the first magnetic plate 337, and the outer wall of the sliding rod 331 between the first magnetic plate 337 and the vertical plate 3311 is sleeved with a first spring 336, and a spring 336 is provided below the sliding rod 331 for pushing the first magnetic plate 33 The pushing mechanism of the first spring 336 is compressed, and the first magnetic plate 337 is driven to move toward the vertical plate 3311 through the pushing mechanism, so as to increase the clamping distance between the first clamping member 33 and the second clamping member 34. After the transformer core to be wound is rotated between the first clamping member 33 and the second clamping member 34, the pushing mechanism is removed, and the first magnetic plate 337 is driven to move away from the vertical plate 3311 by the resilience of the first spring 336, so as to increase the clamping force of the first clamping member 33 and the second clamping member 34 on the transformer core, thereby improving the firmness of the transformer core clamping.

[0045] The outer wall of the sliding rod 331 is symmetrically provided with sliding grooves 333, and the inner wall of the connecting block 335 is symmetrically fixed with protrusions, and the protrusions slide in the sliding grooves 333, so that the connecting block 335 can drive the sliding rod 331 to rotate, and the sliding rod 331 can also slide inside the connecting block 335, which is convenient for moving the position of the first magnetic plate 337 and rotating the first magnetic plate 337, and facilitating the rotation of the transformer core fixed on the first magnetic plate 337 for coil winding.

[0046] The driving mechanism includes a connecting seat 338. One end of the connecting seat 338 is rotatably connected to the vertical plate 3311, and a motor 334 is installed through the vertical plate 3311 at one end of the connecting seat 338. A second electric push rod 339 is fixed to the other end of the connecting seat 338. A push plate 3310 is fixed to the piston rod end of the second electric push rod 339. The push plate 3310 and the second electric push rod 339 form an L-shaped structure. The second electric push rod 339 drives the push plate 3310 to move, so that the end of the push plate 3310 away from the second electric push rod 339 coincides with the first magnetic attraction plate 337. Then, the second electric push rod 339 drives the push plate 3310 to move horizontally in the reverse direction, so that the push plate 3310 pushes the first magnetic attraction plate 337 to move closer to the vertical plate 3311, so as to compress the first spring 336 by the first magnetic attraction plate 337, thereby increasing the distance between the first magnetic attraction plate 337 and the second clamping member 34. When the first magnetic attraction plate 337 needs to clamp the transformer core, the motor 334 drives the connecting seat 338 to rotate, so that the push plate 3310 rotates around the axis of the second electric push rod 339, and the other end of the push plate 3310 moves away from the first magnetic attraction plate 337. At this time, the resilience of the first spring 336 drives the first magnetic attraction plate 337 to move in the reverse direction, so as to reduce the distance between the first magnetic attraction plate 337 and the second clamping member 34, thereby increasing the clamping force on the transformer core.

[0047] As Figure 8 shown, the second clamping member 34 includes a U-shaped plate 341 and a transmission shaft 346. A rotating shaft 342 is rotatably connected to the middle of the U-shaped plate 341. Second magnetic attraction plates 343 are fixed to both ends of the rotating shaft 342. A first bevel gear 344 is sleeved on the middle of the rotating shaft 342. One end of the transmission shaft 346 is rotatably connected to the upper end of the protective box 32, and one end of the transmission shaft 346 passes through the top wall of the protective box 32 and is connected to the transmission mechanism 35. A second bevel gear 345 is fixed to the other end of the transmission shaft 346, and the first bevel gear 344 meshes with the second bevel gear 345. The second motor 36 drives the transmission shaft 346 to rotate through the transmission mechanism 35, so that the transmission shaft 346 drives the rotating shaft 342 to rotate through the meshed first bevel gear 344 and second bevel gear 345, thereby driving the second magnetic attraction plate 343 to rotate. The relative adsorption force between the second magnetic attraction plate 343 and the first magnetic attraction plate 337 is used to adsorb and fix the transformer core. The second magnetic attraction plate 343 drives the first magnetic attraction plate 337 and the transformer core to rotate, so as to facilitate the coil winding of the transformer core.

[0048] The first magnetic plate 337 and the second magnetic plate 343 are configured in the same manner, and electromagnets are embedded in the first magnetic plate 337 and the second magnetic plate 343 to ensure that the first magnetic plate 337 has a magnetic adsorption function when powered on, but does not have a magnetic adsorption function when powered off, so as to flexibly power on or off according to the clamping requirements of the transformer core.

[0049] like Figure 6 As shown, the transmission mechanism 35 includes a driving gear rotatably mounted on the top of the protective box 32 and a driven gear mounted on one end of a transmission shaft 346, the driven gear meshes with the driving gear, the second motor 36 is mounted on the rotating shaft of one of the driving gears, the driving gear is driven to rotate by the second motor 36, the driving shaft 346 is driven to rotate by the meshing of the driving gear and the driven gear, so as to drive the rotating shaft 342 to rotate through the transmission shaft 346, thereby driving the second magnetic plate 343 to rotate. The transmission mechanism 35 can also adopt the form of a transmission sprocket, a transmission sprocket is mounted on one end of the transmission shaft 346, and then the two transmission sprockets are driven by a transmission chain, the second motor 36 is mounted on one end of one of the transmission shafts 346, so that the second motor 36 drives the two transmission sprockets to rotate through the transmission chain, so that the transmission sprocket drives the transmission shaft 346 to rotate, and the first bevel gear 344 and the second bevel gear 345 drive the rotating shaft 342 to rotate, thereby driving the second magnetic plate 343 to rotate, so as to facilitate the coil winding of the transformer core.

[0050] A traction mechanism 4 is installed above the protective box 32, and the traction mechanism 4 reciprocates on the upper surface of the protective box 32 through a horizontal moving mechanism. The traction mechanism 4 includes a fixed plate 41 and a plurality of traction members 42 installed on the fixed plate 41. Each of the clamping spaces corresponds to a traction member 42, and a coil monitoring component 5 for monitoring the number of coil windings is installed on one of the first clamping members 33.

[0051] like Figures 9-11 As shown, the traction member 42 includes two vertical plates 421, and two T-shaped rods 424 are slidably inserted at the upper end of each vertical plate 421. A fixing block 425 is fixed at one end of the T-shaped rod 424, and a guide wheel 422 is rotatably connected between the two fixing blocks 425. The outer wall of the guide wheel 422 is provided with a guide groove 423, and the outer side of the T-shaped rod 424 between the fixing block 425 and the vertical rod is sleeved with a second spring 426. The guide wheels 422 on the two vertical plates 421 are in conflict with each other, and the guide grooves 423 on the two guide wheels 422 are aligned. The coil is passed through the guide groove 423 between the two guide wheels 422, and the coil is pulled by the guide groove 423. Then, the traction member 42 is driven to reciprocate a certain distance by the horizontal moving mechanism, so as to evenly wind the coil around different positions of the transformer core on the clamping mechanism.

[0052] The horizontal moving mechanism includes a horizontal moving seat 46, the internal rotation of the horizontal moving seat 46 is connected to a screw rod 49, the screw rod 49 is threadedly connected to a sliding platform 48, and the sliding platform 48 is slidably connected to the horizontal moving seat 46, one end of the screw rod 49 is installed with a third motor 47, a support block 44 is fixed on the sliding platform 48, the upper end of the support block 44 is fixed to the lower surface of the fixed plate 41, and sliding blocks 43 are fixed at both ends of the lower surface of the fixed plate 41. The upper surface of the protective box 32 is provided with a sliding groove 45 for the sliding block 43 to slide. The screw rod 49 is driven to rotate by the third motor 47, so that the screw rod 49 and the threaded cooperation of the sliding platform 48 drive the sliding platform 48 and the fixed plate 41 to reciprocate on the horizontal moving seat 46, thereby adjusting the displacement of the traction position of the coil on the traction member 42, so as to facilitate the coil to be evenly wound on the surface of the transformer core.

[0053] The coil monitoring component 5 includes a mounting plate 51, a touch sensor 52 and a touch block 53. The mounting plate 51 is fixed inside the U-shaped plate 341, the touch sensor 52 is fixed on the lower surface of the mounting plate 51, and the touch block 53 is fixed on the outer wall of one end of the rotating shaft 342. When the rotating shaft 342 rotates one circle, the touch block 53 touches the touch sensor 52 once, and a circle of the transformer core clamped on the clamping mechanism is wound around the transformer core, so as to monitor the number of coil turns wound on the transformer core in real time. In addition, the length of the coil wound outside the transformer core can also be calculated by the number of coil turns wound on the transformer core, so as to confirm the usage of the coil. Moreover, since multiple clamping mechanisms are connected through the transmission mechanism 35, it is only necessary to monitor the number of coil turns on one clamping mechanism to know the number of coil turns on other clamping mechanisms, which reduces the cost of monitoring the number of coil turns to a certain extent.

[0054] When in use, the pay-off assembly 1 is used to pay-off multiple coils at the same time, and the coils after paying-off are pulled onto the traction mechanism 4 through the traction assembly 2. Each clamping mechanism can clamp two coils, and multiple transformer cores are clamped at the same time by multiple clamping mechanisms. The coils on the traction mechanism 4 are pulled onto the clamped transformer core, and the transformer core is rotated by the second clamping member 34 to achieve the purpose of winding multiple coils at the same time. At the same time, the coil monitoring assembly 5 is used to monitor the number of turns of the coil on the transformer core, thereby improving the production rate of the transformer to a certain extent and providing convenience for mass production.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
