Description

Technical Field

[0001] The invention relates to the technical field of transformer manufacturing, in particular to a high-strength transformer coil varnish dipping device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components include primary coil, secondary coil and iron core. During the manufacturing process, the transformer coil needs to be varnished to ensure its insulation. Varnishing 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 patent announcement number CN221596193U relates to the field of transformer manufacturing technology. The patent discloses a transformer coil varnishing device, which belongs to the field of transformer coil production technology. It aims at the problems of high labor cost and low production efficiency when varnishing transformer coils. The device comprises a U-shaped plate, which is fixed in the middle of the top wall of the varnishing pool, and a cylinder is fixed in the middle of the outer top wall of the U-shaped plate. A connecting plate is fixed at the output end of the cylinder, and vertical plates are fixed at both ends of the middle of the bottom wall of the connecting plate. A bidirectional screw is rotatably connected in the middle between the two sets of vertical plates, and arc plates are threadedly connected on both sides of the outer periphery of the bidirectional screw, and inner clamps are fixed at the bottom of the side wall away from the arc plate. The patent starts the fan and the heating tube after the varnishing of the coil body is completed. During the operation of the heating tube, the temperature of the inner side of the installation tube is increased, and at the same time, the fan generates airflow inside the installation tube, and the heat flow inside the installation tube is blown to the left and right sides of the coil body, so as to quickly dry the coil body, thereby improving the varnishing efficiency of the transformer coil.

[0004] In the above patent, the coil body is quickly dried to improve the paint dipping efficiency of the transformer coil. However, the current measuring equipment has the following problems: if anti-reversal treatment is not performed after clamping the transformer, external force may accidentally touch the winding, making the clamping ineffective. If preheating is not performed, the moisture in the winding may not be completely removed, which will affect the adhesion and drying speed of the paint, and thus affect the quality of the paint dipping.

The ratchet is fixedly installed on the circumferential surface of the rotating rod, and the pawl is slidably installed on the surface of the fixing frame. The receiving rod is fixedly installed on the bottom of the fixing frame, the driving button is fixedly installed on the bottom of the receiving rod, and the pressure plate is fixedly installed on the bottom of the inner support plate.

[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.

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: (1) The invention places the transformer on the outer wall of the inner support plate by setting a paint dipping device, and moves the inner support plates on both sides outward by a rotating rod until the transformer is fixed. After the transformer is fixed, if the rotating rod is accidentally touched by external force, the rotating rod will be reversed. The ratchet and pawl prevent the rotating rod from reversing, and prevent the rotating rod from loosening due to vibration or other reasons during use, resulting in loss of clamping 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 performed by the heating component. The transformer is driven to rotate by the driving motor and the fixing frame, so that various parts of the transformer can be heated evenly, thereby improving the preheating efficiency and avoiding local overheating or overcooling.

[0015] (2) The invention, through the setting of the auxiliary device, after the paint liquid is added to the liquid storage tank and preheating is completed, the pressing plate moves to contact the rotating frame to make the rotating frame rotate, and 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 docking button rotates in coordination with the telescopic rod and the T-shaped rod to drive the mixing rod to rotate. The rotation of the mixing rod causes the paint liquid to be stirred. The stirring can prevent the solid particles in the paint liquid from settling, maintain the viscosity and fluidity of the paint liquid, so that the paint liquid can better penetrate into the interior of the transformer, thereby improving the effect of immersion. At the same time, the floating plate moves upward so that the paint liquid accumulated at the bottom of the liquid storage tank is drained into the working range of the mixing rod to prevent the paint liquid from settling. During the immersion process, the rubber button is driven to move back and forth left and right by the dual-axis motor, the rotating frame, and the rotating shaft. The rubber button continuously contacts the outer wall of the liquid storage tank to generate vibration, so that the bubbles in the paint liquid are eliminated, thereby improving the efficiency of immersion.

[0016] (3) The invention, by setting up a pretreatment device, adds the paint liquid into the treatment tank for pretreatment before the paint liquid enters the liquid storage tank. First, the paint is filtered through a filter plate to remove impurities and particles in the paint to prevent impurities from entering the paint dipping tank and affecting the paint dipping effect. The paint is stirred by a rotating shaft and a 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 it is necessary to add paint, the paint in the treatment tank is allowed to enter the liquid storage tank by opening the valve. The disk is fixed by the docking port, the plug rod, and the No. 3 spring, that is, the transformer reaches the set paint dipping position, which can prevent the transformer from being displaced during the paint dipping process and ensure that the insulating paint can evenly cover the surface of the coil and fill its gaps and micropores. The filter plate moves up and down to form different flow paths for the paint on the filter plate, thereby increasing the contact opportunity between the paint and the filter plate and improving the filtration efficiency.

[0021] The bottom of the pawl 10 is set as an inclined surface, and a No. 1 spring is arranged between the pawl 10 and the fixing frame 6. The pawl 10 is reset by the arranged No. 1 spring. After the transformer is fixed, if the external force accidentally touches the rotating rod 7, the rotating rod 7 will be reversed. At this time, the ratchet 9 will contact the non-inclined surface of the pawl 10.

The rotation of the fixed frame 6 drives the transformer to rotate, so that various parts of the transformer can be heated evenly, thereby improving the preheating efficiency and avoiding local overheating or overcooling.

[0023] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, an auxiliary device and a pretreatment device are arranged above the base 1, and 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, and the mixing rod 21 is fixedly installed on the circumferential surface of the T-shaped rod 20. The circumferential surface of the T-shaped rod 20 is provided with a reciprocating spiral groove, and 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 settling, 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 immersion. The floating plate 22 moves so that the paint liquid accumulated at the bottom of the liquid storage tank 2 is drained into the working range of the mixing rod 21 to prevent the paint liquid from settling.

[0027] 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.

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.

[0029] When the present 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, the driving button 12 and the pressure plate 13 are driven to move. The movement of the pressure plate 13 will contact the rotating frame 23 to make the rotating frame 23 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 No. 2 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, 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 settling, 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 dipping. The T-shaped rod 20 rotates and drives the reciprocating spiral groove to rotate. The floating plate 22 moves upward through the reciprocating spiral groove. 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 the paint liquid from settling. During the dipping process, the output end of the dual-axis motor 27 drives the rotating frame 281 to rotate. The output end of the dual-axis motor 27 rotates and drives the No. 1 belt to drive the rotating shaft 29 to rotate. The rotation of the rotating frame 281 drives the rubber button 28 to move back and forth left and right. The rubber button 28 continuously contacts the outer wall of the liquid storage tank 2 to generate vibration, so that the bubbles in the paint liquid are eliminated, thereby improving the efficiency of dipping. Before the paint liquid enters the liquid storage tank 2, the paint liquid is added to the processing 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 paint dipping tank and affecting the paint dipping effect. The paint is stirred by the stirring rod 31 driven by the rotation of the shaft 29. 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 paint needs to be added, the paint in the processing tank 30 is allowed to enter the liquid storage tank 2 by opening the valve 32. When the disc 4 continues to descend to the paint dipping range, the outer wall of the docking port 14 will contact the inclined surface of the plug rod 34, causing the plug rod 34 to move outward and compress the No. 3 spring 35. When the docking port 1 4 overlaps with the plug rod 34, at this time, the third spring 35 is released and drives the plug rod 34 to be inserted into the docking port 14, and the fixation of the disc 4 is completed at this time, that is, the transformer reaches the set paint dipping position, which can prevent the transformer from being displaced during the paint dipping process, and ensure that the insulating paint can evenly cover the coil surface 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, so that the arc rod 37 moves upward, and 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, and the filter plate 36 can form different flow paths on the filter plate 36 by moving the filter plate 36 up and down, thereby increasing the contact opportunity between the paint and the filter plate 36, thereby improving the filtration efficiency.
