Description

Technical Field

[0001] The present invention relates to the technical field of transformer manufacturing, and particularly to a high-strength transformer coil impregnating device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components include a primary coil, a secondary coil, and an iron core. During the manufacturing process of a transformer coil, in order to ensure its insulation performance, it needs to be impregnated with paint. Impregnating with paint can not only enhance the insulation performance of the coil, but also improve its heat resistance, moisture resistance, and corrosion resistance, thereby extending the service life of the transformer.

[0003] The patent with the patent announcement number CN221596193U relates to the technical field of transformer manufacturing. This patent discloses a transformer coil impregnating device, belonging to the technical field of transformer coil production. Aiming at the problems of high labor cost and low production efficiency during the impregnation of transformer coils, it includes a U-shaped plate fixed in the middle of the top wall of the impregnation tank. In the middle of the outer top wall of the U-shaped plate, a cylinder is fixed. The output end of the cylinder is fixed with a connecting plate. At the middle of the bottom wall of the connecting plate, vertical plates are fixed at both the left and right ends. In the middle between the two groups of vertical plates, a bidirectional screw is rotatably connected. On the left and right sides of the outer circumference of the bidirectional screw, arc-shaped plates are threadedly connected. At the bottom of the side walls away from each other of the arc-shaped plates, inner clamping blocks are fixed. After the impregnation of the coil body is completed, the patent starts the fan and the heating tube. During the working process of the heating tube, the temperature inside the installation tube rises. At the same time, the fan works to generate an air flow inside the installation tube, blowing the hot air flow inside the installation tube to both sides of the coil body to quickly dry the coil body, improving the impregnation efficiency of the transformer coil.

[0004] In the above patent, the coil body is quickly dried, improving the impregnation efficiency of the transformer coil. However, the current measuring equipment has the following problems: If anti-reversal treatment is not carried out after clamping the transformer, it may cause the clamping to lose its effect due to accidental external contact. And if preheating is not carried out, the moisture in the winding may not be completely removed, which will affect the adhesion and drying speed of the paint, and further affect the quality of impregnation.

[0011] According to the above technical solution, the auxiliary device also includes a rubber button and a rotating shaft. The rubber button is fixedly mounted on the inner wall of the rotating frame. One side of the rotating shaft is transmission-connected to the output end of the dual-axis motor through a No. 1 belt. When the output end of the dual-axis motor rotates, the No. 1 belt is driven to drive the rotating shaft to rotate.

The treatment tank is fixedly installed on the top of the base, and the other side of the rotating shaft is rotatably installed on the inner wall of the treatment tank.

When the disc continues to descend to the paint immersion range, the outer wall of the docking interface will contact the inclined surface of the insert block rod, causing the insert block rod to move outward and compress the No. 3 spring at the same time. When the docking interface overlaps with the insert block rod, the No. 3 spring is released and drives the insert block rod to be inserted into the docking interface, and the fixation of the disc is completed at this time.

[0014] The present invention provides a high-strength transformer coil varnish dipping device, which has the following beneficial effects:

[0015] (1) In this invention, through the setting of the dipping paint device, the transformer is placed on the outer wall of the inner support plate. The two inner support plates move outward through the rotating rod until the transformer is fixed. After the transformer is fixed, if an external force accidentally touches the rotating rod, the rotating rod will reverse. The ratchet and pawl are used to prevent the rotating rod from reversing, preventing the rotating rod from loosening due to vibration or other reasons during use and causing the clamping to lose its effect. After the transformer is clamped, the output end of the linear motor drives the disc to move downward to the heating component area, and preheating is carried out through the heating component. The transformer is driven to rotate by the driving motor and the fixing frame, which can make all parts of the transformer evenly heated, thereby improving the preheating efficiency and avoiding the occurrence of local overheating or overcooling.

[0016] (2) In this invention, through the setting of the auxiliary device, after adding the paint liquid into the liquid storage tank and after preheating, the pressing plate moves to contact the rotating frame, causing the rotating frame to rotate. The rotating frame, the telescopic rod, and the second spring drive the docking button to move until it contacts the driving button. The driving button rotates to drive the docking button to rotate. The rotation of the docking button, in cooperation with the telescopic rod and the T-shaped rod, drives the mixing rod to rotate. The rotation of the mixing rod stirs the paint liquid. Stirring can prevent the solid particles in the paint liquid from precipitating, maintaining the viscosity and fluidity of the paint liquid, so that the paint liquid can better penetrate into the interior of the transformer, improving the dipping paint effect. At the same time, the floating plate moves upward, causing the paint liquid accumulated at the bottom of the liquid storage tank to be drained into the working range of the mixing rod, preventing this paint liquid from precipitating. During the dipping paint process, the rubber button moves left and right reciprocally driven by the double-shaft motor, the rotating frame, and the rotating shaft. The rubber button continuously contacts the outer wall of the liquid storage tank to generate vibration, eliminating the bubbles in the paint liquid and improving the dipping paint efficiency.

[0017] (3) In this invention, through the setting of the pretreatment device, the paint liquid is added to the treatment tank for pretreatment before entering the liquid storage tank. First, it is filtered through the filter plate to remove impurities and particles in the paint to prevent impurities from entering the dipping paint tank and affecting the dipping paint effect. The paint is stirred by the rotating shaft and the stirring rod. The paint may precipitate during storage, so it needs to be stirred before use to ensure that the components of the paint are evenly mixed. When the paint needs to be added, the paint in the treatment tank enters the liquid storage tank by opening the valve. The fixing of the disc is completed through the docking interface, the plug rod, and the third spring. That is, when the transformer reaches the set dipping paint position, it can prevent the transformer from shifting during the dipping paint process, ensuring that the insulating paint can evenly cover the surface of the coil and fill its gaps and micropores. By moving the filter plate up and down, different flow paths of the paint can be formed on the filter plate, increasing the contact opportunity between the paint and the filter plate, thereby improving the filtering efficiency.

[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] See also Figures 1 - 3, an embodiment of the present invention is: a high-strength transformer coil impregnating device, including a base 1. Above the base 1, there is an immersion device. The immersion device includes a liquid storage tank 2, a linear motor 3, a disc 4, a driving motor 5, a fixing frame 6, a rotating rod 7, an inner support plate 8, a ratchet 9, a pawl 10, a receiving rod 11, a driving button 12, a pressing plate 13, a docking port 14 and a heating component 15. The liquid storage tank 2 is fixedly installed at the bottom of the base 1. The fixed end of the linear motor 3 is fixedly installed at the top of the base 1. The disc 4 is fixedly installed at the output end of the linear motor 3. The fixed end of the driving motor 5 is fixedly installed at the top of the disc 4. The fixing frame 6 is fixedly installed at the output end of the driving motor 5. The rotating rod 7 is rotatably installed on the inner wall of the fixing frame 6. A bidirectional spiral groove is provided on the circumferential surface of the rotating rod 7. The inner support plate 8 is threadedly installed on the circumferential surface of the rotating rod 7. The ratchet 9 is fixedly installed on the circumferential surface of the rotating rod 7. The pawl 10 is slidably installed on the surface of the fixing frame 6 to prevent the rotating rod 7 from reversing, which can prevent the rotating rod 7 from loosening due to vibration or other reasons during use and resulting in the loss of clamping effect. The receiving rod 11 is fixedly installed at the bottom of the fixing frame 6. The driving button 12 is fixedly installed at the bottom of the receiving rod 11. The pressing plate 13 is fixedly installed at the bottom of the inner support plate 8. The docking port 14 is provided on the circumferential surface of the disc 4. The heating component 15 is provided on the circumferential surface of the liquid storage tank 2, which can make all parts of the transformer uniformly heated, thereby improving the preheating efficiency and avoiding the occurrence of local overheating or overcooling.

[0028] The bottom of the pawl 10 is set as an inclined surface. There is a first spring between the pawl 10 and the fixing frame 6. By setting the first spring to drive the pawl 10 to reset, after the transformer is fixed, when the rotating rod 7 is accidentally touched by an external force, the rotating rod 7 will reverse. At this time, the ratchet 9 will contact the non-inclined surface of the pawl 10. At this time, the pawl 10 will limit the movement of the ratchet 9, that is, prevent the rotating rod 7 from reversing.

[0029] When this embodiment works, the transformer is placed on the outer wall of the inner support plate 8. At this time, the rotating rod 7 is rotated counterclockwise to drive the rotation of the bidirectional thread groove. Through the rotation of the bidirectional thread groove, the two inner support plates 8 move outward until the transformer is fixed. When the inner support plate 8 moves, it drives the pressing plate 13 to move. While the rotating rod 7 rotates, it drives the ratchet 9 to rotate. The rotation of the ratchet 9 contacts the inclined surface of the pawl 10, causing the pawl 10 to move downward and compress the first spring. At this time, the pawl 10 does not restrict the rotation of the ratchet 9. After the transformer is fixed, if an external force accidentally touches the rotating rod 7, the rotating rod 7 will reverse. At this time, the ratchet 9 will contact the non-inclined surface of the pawl 10, and at this time, the pawl 10 will restrict the movement of the ratchet 9, that is, prevent the rotating rod 7 from reversing, which can prevent the rotating rod 7 from loosening due to vibration or other reasons during use and resulting in the loss of clamping effect. After the transformer is clamped, the output end of the linear motor 3 drives the disc 4 to move downward. While the disc 4 moves, it drives the docking port 14 to move. When the disc 4 moves to the preheating range of the heating assembly 15, the linear motor 3 stops working at this time. Then, the driving motor 5 drives the fixing frame 6 to rotate. While the fixing frame 6 rotates, it drives the receiving rod 11 to rotate. The rotation of the receiving rod 11 drives the driving button 12 to rotate, and the rotation of the fixing frame 6 drives the transformer to rotate, which can make all parts of the transformer evenly heated, thereby improving the preheating efficiency and avoiding the occurrence of local overheating or overcooling.

[0030] Please refer to Figures 1 - 7 , on the basis of the above embodiment, in another embodiment of the present invention, an auxiliary device and a pretreatment device are provided above the base 1. The auxiliary device includes a T-shaped rod 20, a mixing rod 21 and a floating plate 22. The T-shaped rod 20 is rotatably installed at the bottom of the inner wall of the liquid storage tank 2. The mixing rod 21 is fixedly installed on the circumferential surface of the T-shaped rod 20. A reciprocating spiral groove is provided on the circumferential surface of the T-shaped rod 20. The floating plate 22 is threadedly installed on the circumferential surface of the T-shaped rod 20. Stirring can prevent the solid particles in the paint liquid from precipitating, maintain the viscosity and fluidity of the paint liquid, so that the paint liquid can better penetrate into the interior of the transformer and improve the dipping effect. The movement of the floating plate 22 causes the paint liquid accumulated at the bottom of the liquid storage tank 2 to be drained into the working range of the mixing rod 21 to prevent these paint liquids from precipitating.

[0031] The auxiliary device further includes a rotating frame 23, a telescopic rod 241, a docking button 24 and a second spring 25. The rotating frame 23 is rotatably installed on the surface of the T-shaped rod 20. The fixed end of the telescopic rod 241 is fixedly installed on the inner wall of the T-shaped rod 20. The docking button 24 is fixedly installed on the movable end of the telescopic rod 241. The second spring 25 is arranged between the telescopic rod 241 and the T-shaped rod 20. By setting the second spring 25 to drive the telescopic rod 241 to reset, after the driving button 12 contacts the docking button 24, the rotation of the driving button 12 drives the docking button 24 to rotate.

[0032] The auxiliary device also includes a connecting plate 26, a dual-axis motor 27 and a rotating frame 281. The connecting plate 26 is fixedly mounted on the circumferential surface of the liquid storage tank 2, and the fixed end of the dual-axis motor 27 is fixedly mounted on the inner wall of the connecting plate 26. One side of the rotating frame 281 is fixedly mounted on the output end of the dual-axis motor 27, and the other side of the rotating frame 281 is rotatably mounted on the top of the base 1, and the rotating frame 281 is driven to rotate through the output end of the dual-axis motor 27.

[0033] The auxiliary device also includes a rubber button 28 and a rotating shaft 29. The rubber button 28 is fixedly mounted on the inner wall of the rotating frame 281. One side of the rotating shaft 29 is transmission-connected to the output end of the dual-axis motor 27 via a No. 1 belt. The rubber button 28 continuously contacts the outer wall of the liquid storage tank 2 to generate vibration, thereby eliminating bubbles in the paint liquid and improving the efficiency of the paint dipping.

[0034] The pretreatment device includes a treatment tank 30, a stirring rod 31 and a valve 32. The treatment tank 30 is fixedly installed on the top of the base 1, and the other side of the rotating shaft 29 is rotatably installed on the inner wall of the treatment tank 30. The stirring rod 31 is fixedly installed on the circumferential surface of the rotating shaft 29. The treatment tank 30 is connected with the liquid storage tank 2 through a pipeline, and the valve 32 is arranged on the circumferential surface of the pipeline. Before the paint liquid enters the liquid storage tank 2, the paint liquid is added to the treatment tank 30 for pretreatment. The stirring rod 31 is driven by the rotation of the rotating shaft 29 to stir the paint. The paint may precipitate during the storage process, so it needs to be stirred before use to ensure that the components of the paint are evenly mixed. When paint needs to be added, the valve 32 is opened to allow the paint in the treatment tank 30 to enter the liquid storage tank 2.

[0035] The pretreatment device also includes a hollow block 33, a plug-in rod 34, a No. 3 spring 35, a filter plate 36 and an arc rod 37. The hollow block 33 is fixedly penetrated through the inner and outer walls of the liquid storage tank 2, the plug-in rod 34 is slidably installed on the inner wall of the hollow block 33, and the No. 3 spring 35 is arranged between the hollow block 33 and the plug-in rod 34. The plug-in rod 34 is reset by the arranged No. 3 spring 35. The top of the plug-in rod 34 is arranged as an inclined surface, which can prevent the transformer from shifting during the varnishing process, ensure that the insulating paint can evenly cover the surface of the coil, fill its gap and The micropore filter plate 36 is slidably mounted on the inner wall of the processing tank 30, and the arc rod 37 is fixedly mounted on the bottom of the filter plate 36. The bottom of the arc rod 37 is set as an inclined surface. A No. 4 spring is arranged between the filter plate 36 and the processing tank 30. The arc setting at the bottom of the arc rod 37 enables the arc rod 37 to move up and down when the stirring rod 31 rotates. The filter plate 36 is reset by the arranged No. 4 spring, and firstly filtered through the filter plate 36 to remove impurities and particles in the paint to prevent impurities from entering the paint dipping tank and affecting the paint dipping effect.

[0036] When this embodiment is working, the paint liquid is stored in the liquid storage tank 2. After preheating, the output end of the linear motor 3 continues to drive the disc 4 to descend, that is, drives the driving button 12 and the pressing plate 13 to move. The movement of the pressing plate 13 will contact the rotating frame 23 and cause the rotating frame 23 to rotate. The rotation of the rotating frame 23 drives the movable end of the telescopic rod 241 to move upward, and at the same time stretches the second spring 25. The fixed end of the telescopic rod 241 moves to drive the docking button 24 to move until it contacts the driving button 12. After the driving button 12 contacts the docking button 24, at this time, the driving button 12 rotates to drive the docking button 24 to rotate. The rotation of the docking button 24 drives the movable end of the telescopic rod 241 to rotate. The rotation of the movable end of the telescopic rod 241 drives the T-shaped rod 20 to rotate. The rotation of the T-shaped rod 20 drives the mixing rod 21 to rotate. The rotation of the mixing rod 21 stirs the paint liquid. Stirring can prevent the solid particles in the paint liquid from precipitating and maintain the viscosity and fluidity of the paint liquid, so that the paint liquid can better penetrate into the interior of the transformer and improve the effect of impregnating paint. At the same time as the T-shaped rod 20 rotates, it drives the reciprocating spiral groove to rotate. Through the reciprocating spiral groove, the floating plate 22 moves upward. The movement of the floating plate 22 diverts the paint liquid accumulated at the bottom of the liquid storage tank 2 into the working range of the mixing rod 21 to prevent this paint liquid from precipitating. During the impregnating paint process, the output end of the double-shaft motor 27 drives the rotating frame 281 to rotate. While the output end of the double-shaft motor 27 rotates, it drives the first belt to drive the rotating shaft 29 to rotate. The rotation of the rotating frame 281 drives the rubber button 28 to move left and right reciprocally. The continuous contact of the rubber button 28 with the outer wall of the liquid storage tank 2 generates vibration, so that the bubbles in the paint liquid are eliminated and the efficiency of impregnating paint is improved;

[0037] Before the paint liquid enters the liquid storage tank 2, the paint liquid is added to the treatment tank 30 for pretreatment. First, it is filtered through the filter plate 36 to remove impurities and particles in the paint to prevent impurities from entering the dipping tank and affecting the dipping effect. The stirring rod 31 is driven to rotate by the rotating shaft 29 to stir the paint. The paint may precipitate during storage, so it needs to be stirred before use to ensure that the components of the paint are evenly mixed. When the paint needs to be added, the paint in the treatment tank 30 enters the liquid storage tank 2 by opening the valve 32. When the disc 4 continuously descends to the dipping range, the outer wall of the butt joint 14 will contact the inclined surface of the plug rod 34 at this time, causing the plug rod 34 to move outward and compress the third spring 35 at the same time. When the butt joint 14 overlaps with the plug rod 34, the third spring 35 is released at this time and drives the plug rod 34 to insert into the butt joint 14. At this time, the fixation of the disc 4 is completed, that is, the transformer reaches the set dipping position, which can prevent the transformer from shifting during the dipping process and ensure that the insulating paint can evenly cover the surface of the coil and fill its gaps and micropores. When the stirring rod 31 rotates, its inclined surface will contact the bottom arc surface of the arc rod 37, causing the arc rod 37 to move upward. The movement of the arc rod 37 drives the filter plate 36 to move. The movement of the filter plate 36 will stretch the fourth spring. By moving the filter plate 36 up and down, different flow paths of the paint can be formed on the filter plate 36, increasing the contact opportunity between the paint and the filter plate 36, thereby improving the filtration efficiency.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
