DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] See also Figure 1-Figure 10 The embodiment of the present invention provides an automatic transformer winding device, comprising a winding auxiliary bracket 1, and further comprising: A gap filling movable opening 2, the 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; and a winding gap control mechanism, the winding gap control mechanism is connected to the winding auxiliary bracket 1 and the coating sliding frame 21 respectively, wherein the winding gap control mechanism includes a progressive pressing component, a filling adjustment component, a multifunctional moving table 4 and a coating control component 5; The progressive pressing assembly is connected to the winding auxiliary bracket 1 and the coating sliding bracket 21 respectively, and the filling adjustment assembly is connected to the winding auxiliary bracket 1 and the coating sliding bracket 21 respectively, and a multifunctional moving platform 4 is also installed on the filling adjustment assembly, and a coating control component 5 is detachably installed on the multifunctional moving platform 4; A detection support 6 is also installed on the progressive clamping assembly. The detection support 6 is electrically connected to the progressive clamping assembly, and a winding clamping roller 7 is rotatably installed on the detection support 6. The coating control component 5 is located above the winding clamping roller 7.

[0029] See also Figure 1-Figure 10 , and also includes: a material discharge cleaning surface 25, which is located on the lower end surface of the coating control component 5 and above the winding pressure roller 7, and the material discharge cleaning surface 25 is also slidably connected to the winding pressure roller 7.

[0030] It also includes: a first follower 28, which is fixedly mounted on the winding auxiliary bracket 1; And a second follower part 30 , the second follower part 30 is fixedly mounted on the multifunctional mobile platform 4 , and a telescopic rod 29 is slidably mounted on the second follower part 30 , and the other end of the telescopic rod 29 is slidably connected to the first follower part 28 .

[0031] In the transformer winding process, in order to ensure the tightness of the winding, a pressure roller is used to press the transformer core at the winding point above the winding roller (such as Figure 1As shown, the winding roller is located below the winding pressure roller 7, and a limiting device is provided to fix the transformer core on the winding roller), to ensure the winding effect. The above are all prior arts and will not be elaborated here. Since the winding pressure roller 7 will exert a certain pressure on the surface of the transformer core, the gap between the wires in the winding process can be reduced. At the same time, during the pressing process of the winding pressure roller 7, first, the winding auxiliary bracket 1 can be installed on the winding equipment by bolt connection, and the winding pressure roller 7 can be placed above the winding roller. The number of winding pressure rollers 7 can also be set in multiples, which can be set according to actual needs. Then, during the transformer winding process, as the wires wound on the transformer core gradually increase, the rolled transformer The diameter of the transformer core will also increase, which will produce pressure on the winding pressure roller 7. In order to ensure that the pressure of the winding pressure roller 7 on the transformer core is approximately the same during the entire winding process, the progressive pressure component can be controlled to start under the detection action of the detection support 6, thereby driving the detection support 6 and the winding pressure roller 7 to move slowly upward, and under the feedback action of the detection support 6, the winding pressure roller 7 moves upward while fully squeezing the wire on the transformer core of the winding. In the process of the detection support 6 and the winding pressure roller 7 moving upward, the progressive pressure component will also push the coating slide frame 21 to move slowly in the gap filling active opening 2, thereby driving the multifunctional moving platform 4 and the coating control component 5 to move synchronously (wherein the coating control component 5 can be in the form of a filler capsule, It can also be in the form of a telescopic chamber, and is provided with a liquid outlet, so that under the pressure of the winding pressure roller 7, the coating control member 5 can be deformed, and the internal filler can flow out and drip evenly on the wire of the transformer core. Other structures can also be used, such as a telescopic cylinder, which will not be described in detail here. The filler can be in the form of resin or insulating varnish, etc., and is evenly coated to further reduce the effect of the gap between the wires. In addition, a sponge or rag can also be provided on the coating control member 5 to wipe and clean the winding pressure roller 7), and the discharge cleaning surface 25 on the coating control member 5 will move on the winding pressure roller 7 to perform coating and cleaning operations (in the process of the winding pressure roller 7 pressing the wire on the transformer core, the winding pressure roller 7 will rotate, and during the rotation process of the winding pressure roller 7, it can contact the discharge cleaning surface 25, so as to clean the surface of the winding pressure roller 7). Since the winding pressure roller 7 will exert a certain pressure on the surface of the transformer core to ensure the tightness of the winding, if the surface of the winding pressure roller 7 is dirty, it will immediately affect the conductor. Therefore, as the winding pressure roller 7 and the discharge cleaning surface 25 slide relative to each other, the surface of the winding pressure roller 7 can be fully cleaned, especially for stubborn stains. In addition, as the multifunctional moving platform 4 and the coating control component 5 move forward, the cleaner part of the coating control component 5 can be continuously used to contact the winding pressure roller 7 during the entire transformer winding process, so as to avoid the problem of secondary pollution. In addition,While the progressive pressing assembly drives the detection support 6 and the winding pressing roller 7 to move slowly upward and drives the multifunctional movable platform 4 and the coating control component 5 to move horizontally, the filling adjustment assembly will also drive the multifunctional movable platform 4 and the coating control component 5 to move slowly upward, and the upward movement of the coating control component 5 is smaller than the upward movement of the winding pressing roller 7. On the one hand, as the use time of the winding pressing roller 7 increases, the possibility of the winding pressing roller 7 being contaminated will also increase, and the adhered dirt may also increase. Therefore, when the upward movement of the coating control component 5 is smaller than the upward movement of the winding pressing roller 7, the winding pressing roller 7 will exert pressure on the coating control component 5, thereby improving the subsequent cleaning degree of the winding pressing roller 7, and the cleaning degree gradually increases, which is beneficial to ensure the cleanliness of the winding pressing roller 7 during use. On the other hand, as the number of layers of the wound wire increases, the pressure between the coating control component 5 and the winding pressing roller 7 increases. When the filling amount is large, the amount of dripping filling can be increased, so as to further ensure the tightness of the winding. In addition, during the movement of the multifunctional movable platform 4 and the coating control part 5 relative to the winding auxiliary bracket 1, the first follower 28, the telescopic rod 29 and the second follower 30 can ensure the stability of the movement of the multifunctional movable platform 4 and the coating control part 5. No more details are given here. After a winding work is completed, the coating control part 5 can be cleaned and replaced according to the dirt on the surface of the coating control part 5, and the amount of filler in the coating control part 5 can be supplemented to compact and fill the winding work of the next transformer. The operation is simple. As the thickness of the winding increases, the air gap between the wires can be fully reduced to avoid affecting the conversion efficiency of the transformer, which is conducive to improving the quality and performance of transformer production, and can extend the service life of the transformer, providing convenience for the staff.

[0032] In one embodiment of the present invention, see Figure 1-Figure 10 , the progressive pressing assembly comprises: An asynchronously adjustable telescopic cylinder 12, wherein the asynchronously adjustable telescopic cylinder 12 is rotatably mounted on the winding auxiliary bracket 1, and the asynchronously adjustable telescopic cylinder 12 is also electrically connected to the detection support 6; A movable joint 15, wherein the movable joint 15 is movably connected to the output end of the asynchronous adjustment telescopic cylinder 12, and a push-pull telescopic rod 20 is also installed on the movable joint 15, and the push-pull telescopic rod 20 is fixedly connected to the coating sliding frame 21; And a lifting drive unit, the lifting drive unit is connected to the winding auxiliary bracket 1 and the detection support 6 respectively, and is connected to the movable joint 15.

[0033] The lifting drive unit comprises: A fixed support 3, wherein the fixed support 3 is fixedly mounted on the winding auxiliary bracket 1, and a first rotating shaft 13 is rotatably mounted on the other end of the fixed support 3; A second rotating shaft 14, the second rotating shaft 14 is rotatably connected to the movable joint 15; A synchronous transmission plate 11, wherein the synchronous transmission plate 11 is fixedly connected to the first rotating shaft 13 and the second rotating shaft 14 respectively; 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.

[0034] The lifting module comprises: A lifting slide post 9, wherein the lifting slide post 9 is inserted into the winding auxiliary bracket 1 and is slidably connected to the winding auxiliary bracket 1, and the bottom end of the lifting slide post 9 is detachably connected to the detection support 6; A connecting plate 8, wherein the connecting plate 8 is fixedly mounted on the top end of the lifting slide column 9; A drive connection seat 10, one end of which is detachably connected to the connection plate 8, and the other end of which is provided with a movable opening 19; And a movable column 16 , one end of which is rotatably connected to the synchronous transmission plate 11 , and the other end of which is clamped in the movable opening 19 and movably connected to the movable opening 19 .

[0035] During the transformer winding process, the asynchronous adjustment telescopic cylinder 12 is started to push the synchronous transmission plate 11 to rotate around the first rotating shaft 13, wherein the synchronous transmission plate 11 can adopt a triangle-like structure with three corners, and the three corners are respectively equipped with the first rotating shaft 13, the second rotating shaft 14 and the movable column 16. During the slow rotation of the synchronous transmission plate 11, the driving connection seat 10 can be pushed to move up through the movable column 16. At this time, the movable column 16 can move freely in the movable opening 19. During the upward movement of the driving connection seat 10, the lifting slide column 9 can be driven to slide on the winding auxiliary bracket 1, thereby driving the detection support 6 and the winding pressure roller 7 to move up synchronously to ensure that the winding pressure roller 7 is on the transformer core. The conductor pressure on the surface is always kept approximately the same. In addition, while the asynchronously adjustable telescopic cylinder 12 pushes the movable joint 15 to move, the coating slide frame 21 can also be pushed to move horizontally via the push-pull telescopic rod 20 (during the movement, the push-pull telescopic rod 20 can automatically extend and retract, similar to the form of a cylinder assembly), so that the filling adjustment assembly can drive the multifunctional movable platform 4 and the coating control component 5 to move in translation at the same time (the liquid outlet on the coating control component 5 is always located above the conductor wound on the iron core), and the multifunctional movable platform 4 and the coating control component 5 can be moved upward in a manner lower than the upward movement amplitude of the winding pressure roller 7, thereby achieving real-time cleaning of the winding pressure roller 7 and reducing the gap between the conductors.

[0036] In one embodiment of the present invention, see Figure 1-Figure 10 , the filling adjustment component comprises: A sliding column 26, wherein the sliding column 26 is inserted into the coating sliding frame 21 and is slidably connected to the coating sliding frame 21, and the bottom end of the sliding column 26 is fixedly connected to the multifunctional moving platform 4; An asynchronously adjustable lifting plate 31, wherein the asynchronously adjustable lifting plate 31 is fixedly connected to the top end of the sliding column 26; A return spring 24, two ends of which are fixedly connected to the coating sliding frame 21 and the asynchronous adjustment lifting plate 31 respectively; And an asynchronous lifting unit, wherein the asynchronous lifting unit is connected to the winding auxiliary bracket 1 and connected to the asynchronous adjustment lifting plate 31.

[0037] The asynchronous lifting unit comprises: A follow-up adjustment guide post 32, wherein the follow-up adjustment guide post 32 is fixedly mounted on the asynchronous adjustment lifting plate 31; An asynchronous control inclined frame 23, one end of the asynchronous control inclined frame 23 is fixedly connected to the winding auxiliary bracket 1, and the other end of the asynchronous control inclined frame 23 passes through the coating sliding frame 21 and is fixedly connected to the winding auxiliary bracket 1; and a limiting guide groove 27, wherein the limiting guide groove 27 is provided on the asynchronous control inclined frame 23, wherein the follow-up adjustment guide column 32 is inserted into the limiting guide groove 27 and is slidably connected with the limiting guide groove 27; As the transformer core continues to be wound, the progressive clamping assembly drives the detection support 6 and the winding clamping roller 7 to move slowly upward. At the same time, the limit guide groove 27 will drive the follow-up adjustment guide column 32 to drive the asynchronous adjustment lifting plate 31 to move upward, and drive the multifunctional mobile platform 4 and the coating control component 5 to move upward synchronously. The upward movement amplitude of the coating control component 5 is smaller than the upward movement amplitude of the winding clamping roller 7.

[0038] It also includes: a detection controller 22, which is located on the winding auxiliary bracket 1 and is slidably connected to the coating sliding bracket 21; An air dryer 17, the air dryer 17 is fixedly mounted on the winding auxiliary bracket 1 and is electrically connected to the detection controller 22; And an air outlet pipe 18, wherein the air outlet pipe 18 is fixedly connected to the winding auxiliary bracket 1 and is communicated with the output end of the air dryer 17, and the other end of the air outlet pipe 18 is arranged close to the winding pressure roller 7.

[0039] 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).
