[0002] The automatic winding device for transformers is a key technical equipment that emerges with the increasing importance of the power system and the progress of electrical equipment manufacturing technology. In the power system, transformers play a core role in voltage conversion, efficient power transmission and distribution. Their performance directly affects the stability and safety of the entire power grid. As the core component of transformers, the winding process of coils not only determines the electrical performance, efficiency and service life of transformers, but also deeply affects the manufacturing cost and production efficiency. In view of the problems of low efficiency, difficult to guarantee accuracy and rising labor costs existing in the traditional manual winding method, the automatic winding device for transformers emerges as the times require. During the process of winding the iron core, reducing the air gap between wires helps to reduce the magnetic resistance, otherwise it will affect the magnetic flux passing through the iron core, and further affect the conversion efficiency of the transformer.

On the one hand, as the usage time of the wire winding pressing roller increases, the possibility of the wire winding pressing roller being contaminated also increases, and the adhered dirt may also increase. Therefore, when the upward movement amplitude of the coating control member is smaller than that of the wire winding pressing roller, the wire winding pressing roller will exert a pressure on the coating control member, thereby improving the subsequent cleaning degree of the wire winding pressing roller, and the cleaning degree gradually increases, which is beneficial to ensuring the cleaning degree of the wire winding pressing roller during use. On the other hand, as the number of layers of the wound wire increases, when the pressure between the coating control member and the wire winding pressing roller increases, the amount of the dropped filling agent can be increased, thereby further ensuring the tightness of the winding. In addition, during the movement of the multifunctional moving table and the coating control member relative to the wire winding auxiliary bracket, through the provided first follower part, telescopic rod and second follower part, the smooth movement of the multifunctional moving table and the coating control member can be ensured, which will not be elaborated here. After a wire winding operation is completed, the coating control member can be cleaned and replaced according to the dirt condition on its surface, and the amount of the filling agent in the coating control member can be replenished to perform pressing and filling for the wire winding operation of the next transformer. The operation is simple. As the thickness of the winding continuously increases, the air gap between the wires can be fully reduced, avoiding affecting the conversion efficiency of the transformer, thereby being beneficial to improving the quality and performance of the transformer production and extending the service life of the transformer, providing convenience for the staff.

Detailed implementation manners

[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0056] Please refer to Figures 1 - 10 , a transformer automatic winding device provided by an embodiment of the present invention includes a winding auxiliary bracket 1, and further includes:

[0057] A gap filling movable opening 2 is opened on the winding auxiliary bracket 1, and a coating sliding frame 21 is slidably installed in the gap filling movable opening 2;

[0058] and a winding gap control mechanism, the winding gap control mechanism is respectively connected to the winding auxiliary support 1 and the coating sliding frame 21. Among them, the winding gap control mechanism includes a progressive pressing component, a filling adjustment component, a multi-functional moving platform 4 and a coating control member 5;

[0059] The progressive pressing component is respectively connected to the winding auxiliary support 1 and the coating sliding frame 21. The filling adjustment component is respectively connected to the winding auxiliary support 1 and the coating sliding frame 21. And a multi-functional moving platform 4 is further installed on the filling adjustment component. A coating control member 5 is detachably installed on the multi-functional moving platform 4;

[0060] A detection support 6 is further installed on the progressive pressing component. The detection support 6 is electrically connected to the progressive pressing component. And a winding pressing roller 7 is rotatably installed on the detection support 6. Among them, the coating control member 5 is located above the winding pressing roller 7.

[0061] Please refer to Figures 1 - 10 , it further includes: a feeding cleaning surface 25, the feeding cleaning surface 25 is located on the lower end surface of the coating control member 5, and is located above the winding pressing roller 7. And the feeding cleaning surface 25 is also slidably connected to the winding pressing roller 7.

[0062] It further includes: a first follower part 28, the first follower part 28 is fixedly installed on the winding auxiliary support 1;

[0063] And a second follower part 30, the second follower part 30 is fixedly installed on the multi-functional moving platform 4. And a telescopic rod 29 is slidably installed on the second follower part 30. The other end of the telescopic rod 29 is slidably connected to the first follower part 28.

[0064] During the transformer winding process, in order to ensure the tightness of the winding, the form of a pressing roller is adopted to press the transformer core at the winding place above the winding roller (such as Figure 1As shown, the winding roller is located below the winding pressing roller 7 and is provided with a limiting device to fix the transformer core on the winding roller), ensuring the winding effect. The above are all prior arts and will not be elaborated here. Since the winding pressing roller 7 will exert a certain pressure on the surface of the transformer core, it can reduce the gap between the wires during winding. At the same time, during the pressing process of the winding pressing roller 7, first, the winding auxiliary bracket 1 can be installed on the winding equipment by bolt connection, and the winding pressing roller 7 is placed above the winding roller. Among them, the number of winding pressing rollers 7 can also be set to multiple, which is set according to actual needs. Then, during the winding process of the transformer, as the wires wound on the transformer core gradually increase, the diameter of the coiled transformer core will also become larger, thus exerting a pressure on the winding pressing roller 7. To ensure that the pressure of the winding pressing roller 7 on the transformer core is approximately the same throughout the winding process, under the detection of the detection support 6, the progressive pressing assembly can be controlled to start, thereby driving the detection support 6 and the winding pressing roller 7 to slowly move upward. And under the feedback of the detection support 6, while the winding pressing roller 7 moves upward, the wires on the winding transformer core are fully squeezed. During the upward movement of the detection support 6 and the winding pressing roller 7, the progressive pressing assembly will also push the coating sliding frame 21 to slowly move in the gap filling activity port 2, thereby driving the multi-functional moving platform 4 and the coating control member 5 to move synchronously (wherein, the coating control member 5 can be in the form of a filler bag or a telescopic chamber, and both are provided with liquid outlet holes. Under the pressure of the winding pressing roller 7, the coating control member 5 can be deformed and the internal filler flows out and evenly drips on the wires of the transformer core. It can also adopt other structures, such as a telescopic cylinder, which will not be elaborated here. And the filler can be in the form of resin or insulating paint, etc. After uniform coating, it can further reduce the gap between the wires. In addition, a sponge or a rag can also be provided on the coating control member 5 to wipe and clean the winding pressing roller 7), and the material feeding and cleaning surface 25 on the coating control member 5 will move on the winding pressing roller 7 for coating and cleaning operations (during the process of the winding pressing roller 7 pressing the wires on the transformer core, the winding pressing roller 7 will rotate. During the rotation of the winding pressing roller 7, it can contact the material feeding and cleaning surface 25, thereby realizing the cleaning of the surface of the winding pressing roller 7). Since the winding pressing roller 7 will exert a certain pressure on the surface of the transformer core to ensure the tightness of winding. If the surface of the winding pressing roller 7 is dirty, it will immediately affect the wires. Therefore, as the relative sliding occurs between the winding pressing roller 7 and the material feeding and cleaning surface 25, the surface of the winding pressing roller 7 can be fully cleaned, especially for stubborn stains. In addition, as the multi-functional moving platform 4 and the coating control member 5 move forward, during the entire winding process of the transformer, the relatively clean part of the coating control member 5 can be continuously used to contact the winding pressing roller 7, thereby avoiding the problem of secondary pollution. In addition,While the progressive pressing component drives the detection support 6 and the winding pressing roller 7 to slowly move upward and drives the multi-functional moving platform 4 and the coating control member 5 to translate, the filling adjustment component will also drive the multi-functional moving platform 4 and the coating control member 5 to slowly move upward, and the upward movement amplitude of the coating control member 5 is smaller than that of the winding pressing roller 7. Among them, on the one hand, as the using time of the winding pressing roller 7 increases, the possibility of the winding pressing roller 7 being contaminated also increases, and the adhered dirt may also increase. Therefore, when the upward movement amplitude of the coating control member 5 is smaller than that of the winding pressing roller 7, the winding pressing roller 7 will exert a pressure on the coating control member 5, thereby improving the subsequent cleaning degree of the winding pressing roller 7, and the cleaning degree gradually increases, which is beneficial to ensuring the cleaning degree of the winding pressing roller 7 during use. On the other hand, as the number of layers of the wound wire increases, when the pressure between the coating control member 5 and the winding pressing roller 7 increases, the filling dose that drips can be increased, thereby further ensuring the tightness of the winding. In addition, during the movement of the multi-functional moving platform 4 and the coating control member 5 relative to the winding auxiliary bracket 1, through the provided first follower 28, telescopic rod 29 and second follower 30, the smooth movement of the multi-functional moving platform 4 and the coating control member 5 can be ensured, which will not be elaborated here. After a winding operation is completed, the coating control member 5 can be cleaned and replaced according to the dirt condition on its surface, and the amount of the filler in the coating control member 5 can be replenished to press and fill the winding operation of the next transformer. The operation is simple. As the thickness of the winding continuously increases, the air gap between the wires can be fully reduced, avoiding affecting the conversion efficiency of the transformer, which is beneficial to improving the quality and performance of the transformer production and can extend the service life of the transformer, providing convenience for the staff.

[0073] And a lifting module, the lifting module is connected to the synchronous transmission plate 11 and is respectively connected to the winding auxiliary bracket 1 and the detection support 6.

Among them, the synchronous transmission plate 11 can adopt a structure similar to a triangle, with three corners. The first rotating shaft 13, the second rotating shaft 14, and the movable column 16 are respectively installed at the three corners. During the slow rotation of the synchronous transmission plate 11, it can push the driving connection seat 10 to move upward through the movable column 16. At this time, the movable column 16 can move freely in the movable port 19. During the upward movement of the driving connection seat 10, it can drive the lifting sliding column 9 to slide on the winding auxiliary support 1, so as to drive the detection support 6 and the winding pressing roller 7 to move upward synchronously, so as to ensure that the pressure of the winding pressing roller 7 on the surface of the transformer core wire always remains approximately the same. In addition, during the process of the asynchronous adjustment telescopic cylinder 12 pushing the movable joint 15 to move, it can also push the coating sliding frame 21 to move horizontally through the push-pull telescopic rod 20 (during the movement, the push-pull telescopic rod 20 can automatically expand and contract, similar to the form of a cylinder assembly), so as to drive the multi-functional moving table 4 and the coating control part 5 to move horizontally through the filling adjustment component (the liquid outlet hole on the coating control part 5 is always located above the wire wound on the iron core), and make the multi-functional moving table 4 and the coating control part 5 move upward in a manner lower than the upward movement amplitude of the winding pressing roller 7, so as to realize the real-time cleaning of the winding pressing roller 7 and reduce the gap between the wires.

[0080] In an embodiment of the present invention, please refer to Figures 1 - 10 , the filling adjustment component includes:

[0081] The sliding column 26 is inserted into the coating sliding frame 21, is slidably connected with the coating sliding frame 21, and the bottom end of the sliding column 26 is fixedly connected with the multi-functional moving table 4;

[0082] The asynchronous adjustment lifting plate 31 is fixedly connected with the top end of the sliding column 26;

[0083] The return spring 24 has two ends respectively fixedly connected with the coating sliding frame 21 and the asynchronous adjustment lifting plate 31;

[0084] And an asynchronous lifting unit, which is connected to the winding auxiliary support 1 and is connected to the asynchronous adjustment lifting plate 31.

[0085] The asynchronous lifting unit includes:

[0086] The follow-up adjustment guide post 32 is fixedly installed on the asynchronous adjustment lifting plate 31;

[0087] The asynchronous control inclined frame 23, one end of the asynchronous control inclined frame 23 is fixedly connected to the winding auxiliary support 1, and the other end of the asynchronous control inclined frame 23 penetrates through the coating sliding frame 21 and is fixedly connected to the winding auxiliary support 1;

[0088] And a limit guide groove 27, the limit guide groove 27 is formed on the asynchronous control inclined frame 23, wherein, the follower adjusting guide post 32 is inserted into the limit guide groove 27 and is slidably connected to the limit guide groove 27;

[0089] As the transformer core continues to wind the wire, the progressive pressing assembly drives the detection support 6 and the winding pressing roller 7 to slowly move upward. At the same time, the limit guide groove 27 drives the follower adjusting guide post 32 to drive the asynchronous adjusting lifting plate 31 to move upward, and drives the multifunctional moving table 4 and the coating control member 5 to move upward synchronously, and the upward movement amplitude of the coating control member 5 is less than the upward movement amplitude of the winding pressing roller 7.

[0090] It further includes: a detection controller 22, the detection controller 22 is located on the winding auxiliary support 1 and is slidably connected to the coating sliding frame 21;

[0091] An air dryer 17, the air dryer 17 is fixedly installed on the winding auxiliary support 1 and is electrically connected to the detection controller 22;

[0093] When the coating slide frame 21 slides in the gap filling active opening 2, first, it will drive the sliding column 26 to move synchronously, thereby driving the multifunctional moving platform 4 and the coating control member 5 to translate. In addition, during the movement of the sliding column 26, the follow-up adjustment guide column 32 will slide in the limiting guide groove 27. Since the limiting guide groove 27 is an inclined structure, during the sliding process of the follow-up adjustment guide column 32, the limiting guide groove 27 will generate an upward thrust on the follow-up adjustment guide column 32, thereby causing the asynchronous adjustment lifting plate 31 to move upward, and causing the reset spring 24 to be gradually in a compressed state. As the asynchronous adjustment lifting plate 31 moves upward, the reset spring 24 is gradually compressed. 1 moves upward, the asynchronously adjusted lifting plate 31 can pull the sliding column 26 upward, and drive the multifunctional moving platform 4 and the coating control member 5 to move upward synchronously, wherein, by setting the inclination degree of the limiting guide groove 27, the sliding column 26 can drive the multifunctional moving platform 4 and the coating control member 5 to move upward with a smaller amplitude than the detection support 6 and the winding pressing roller 7 to move upward, so that as the transformer winding work proceeds, the winding pressing roller 7 can gradually exert a greater pressure on the coating control member 5, which is conducive to gradually improving the cleaning degree of the winding pressing roller 7 and the amount of filler added as the transformer winding time goes by. , thereby ensuring the cleaning effect and reducing the gap between the wires. In addition, during the sliding process of the coating slide 21, the relative position with the detection controller 22 will change, wherein the detection controller 22 may have a measurement function to detect the position of the coating slide 21 movement, and compare the displacement of the coating slide 21 with the height of the winding pressure roller 7 upward movement, thereby ensuring the smooth progress of the entire winding work. In addition, as the displacement of the coating slide 21 on the detection controller 22 increases, the air dryer 17 may also be controlled to start, so that the wire wound on the transformer core can be Air is blown on the wire parts to make the filler filled in the gaps between the wires condense quickly to ensure the filling effect. Of course, as the coating sliding rack 21 continues to slide on the detection controller 22, the blowing power of the air dryer 17 can be controlled to gradually increase, so that as the winding time of the transformer increases (the amount of filler also increases), the air drying effect can be gradually improved to further improve the transformer winding and quality and effect (the detection controller 22 can adopt a form similar to a sliding rheostat to control the current passing into the air dryer 17, and can also adopt other existing technologies, which will not be elaborated here).
