Description

Technical Field

[0001] The invention belongs to the technical field of coil varnish dipping, in particular to a coil varnish dipping device for an electronic transformer. Background Art

[0002] The electronic transformer coil is a key component of the transformer, and it plays an important role in converting AC voltage, current and impedance. The electronic transformer coil is an electrical component that inputs and outputs electrical energy in the transformer. It is one of the most basic and important components of the transformer and is often regarded as the "heart" of the transformer. The basic structure of the coil determines the capacity, voltage, current and use conditions of the transformer. The electronic transformer coil varnishing is to immerse a specific insulating varnish into the coil of the electronic transformer, and through immersion, curing and other process steps, a solid paint film is formed on the surface and inside of the coil. This layer of paint film not only improves the insulation performance of the coil, but also enhances its mechanical strength, moisture resistance, corrosion resistance, etc. Conventional electronic transformers need to be treated with a varnishing device when varnishing.

[0003] The conventional varnish dipping device for electronic transformer coils is mainly composed of a clamping device and an immersion tank. When dipping, the coil is clamped by the clamping device and controlled to fall into the immersion tank to realize the varnish dipping operation. This varnish dipping method requires manual cleaning of the coil before varnish dipping to prevent the coil from contaminating the insulating paint and to improve the uniformity of the varnish dipping. However, this process still needs to be completed manually, and the overall varnish dipping efficiency is easily affected to a certain extent.

[0004] At the same time, the conventional paint dipping device only puts the coil into the insulating paint during the paint dipping process. This method makes it difficult to cover the grooves of the coil with insulating paint, resulting in poor uniformity of the overall insulating paint coverage. At the same time, after the paint dipping process, a long period of curing is required before the subsequent coil dipping process can be carried out, and the overall paint dipping quality is poor. Summary of the invention

[0005] The object of the present invention is to provide a coil varnish dipping device for an electronic transformer to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a coil varnish dipping device for an electronic transformer, comprising a base, a support frame is fixedly installed on the top of the outer side surface of the base, a cleaning tank, a varnish dipping tank, and a curing tank are fixedly installed on the top of the base in a clockwise direction, the interior of the cleaning tank is filled with clean water, the interior of the varnish dipping tank is filled with insulating paint, and the interior of the curing tank is installed with an electric heating tube, a fixing ring is provided above the base, the outer side surface of the fixing ring is fixedly connected to the top of the inner side surface of the support frame, and a transmission assembly is movably installed on the inner side surface of the fixing ring.

[0007] In the initial state, the electric push rod is in the longest extension state, that is, the linkage frame is at the highest point. At this time, multiple clamping components are at the highest point, and the coils that need to be dipped in paint are ready. At the same time, it is necessary to ensure that the clean water and insulating paint inside the cleaning tank and the dip paint tank are in sufficient state. At the same time, the liquid level of clean water and insulating paint should be kept within a reasonable range to avoid splashing during use, and complete the preparation work before dipping in paint.

[0008] As a further technical solution of the present invention, the auxiliary component includes a locking frame, the top of which is connected to the outer side surface of the bottom end of the mounting column. The auxiliary component also includes an electromagnet, which is connected to the middle part of the bottom end of the mounting column. The internal movable sleeve of the locking frame is connected with a movable rod, and the movable rod moves up and down relative to the locking frame.

[0009] As a further technical solution of the present invention, the top end of the movable rod passes through the bottom end of the inner side of the locking frame and is fixedly connected to a permanent magnet. The outer side of the movable rod is movably sleeved with a limit spring. The upper and lower ends of the limit spring are respectively connected to the bottom end of the permanent magnet and the bottom end of the inner side of the locking frame.

[0010] As a further technical solution of the present invention, the bottom end of the movable rod passes through the bottom end of the locking frame and is fixedly connected to a movable plate, the outer side surface of the movable plate is connected to the clamping assembly, and the clamping assembly is distributed at equal angles on the outer side surface of the movable plate.

[0011] In the initial state, that is, when the coil is not clamped, the electromagnet is not started, and the limit spring is in the initial state, that is, the permanent magnet is at the lowest point, the limit spring is also at the lowest point, and the clamping assembly is also in the pre-clamping state;

[0012] When the coil is being dipped in paint, the electromagnet can be turned on, and the electromagnet can generate suction to the permanent magnet and drive the permanent magnet to move upward. At this time, the limit spring can be stretched and simultaneously drive the movable rod and the movable plate to move upward and act on the clamping assembly.

[0013] As a further technical solution of the present invention, the clamping assembly includes an L-shaped frame, the top end of the L-shaped frame is connected to the locking frame, the bottom end of the L-shaped frame is fixedly installed with a limiting guide rail, the interior of the limiting guide rail is movably connected to a limiting block, the bottom end of the limiting block is fixedly installed with a splint, and the top end of the limiting block is fixedly installed with a second fixed seat.

[0014] As a further technical solution of the present invention, one end of the second fixed seat away from the limit block is movably connected to a connecting rod via a rotating shaft, and one end of the connecting rod away from the second fixed seat is movably connected to the first fixed seat via a rotating shaft, and the top end of the first fixed seat is connected to the bottom end of the movable plate at a position close to the outer side surface.

[0015] As a further technical solution of the present invention, when the limit spring is in an initial state, the permanent magnet is at the lowest point, and when the permanent magnet and the electromagnet are attracted to each other, the limit spring is in an extreme tension state.

[0016] When the movable plate moves upward, the connecting rod can be driven to deflect synchronously. At this time, multiple connecting rods can be deflected toward the middle, and the limit block can be pulled to move toward the direction of the movable plate. At this time, multiple clamping plates are relatively close to each other. At this time, the coil can be placed between the multiple clamping plates until the multiple clamping plates are in contact with the outer side of the coil, until the clamping process of the coil is completed.

[0017] As a further technical solution of the present invention, an annular groove is provided on the inner side of the fixed ring, and the transmission assembly includes an inner gear ring, and a limiting ring is fixedly sleeved on the outer side of the inner gear ring. The inner gear ring is movably engaged with the annular groove through the limiting ring, and the inner gear ring rotates relative to the fixed ring.

[0018] As a further technical solution of the present invention, the transmission assembly also includes a sun gear located in the middle of the inner gear ring, the outer side surface of the sun gear is meshed and connected with a planetary gear at an equal angle, the other side of the planetary gear is meshed and connected with the inner side surface of the inner gear ring, and the middle part of the bottom end of the planetary gear is connected to the top of the mounting column.

[0019] Before paint dipping, after the three coils are clamped and fixed with the three clamping assemblies in turn, the electric push rod can be turned on and controlled to be shortened. At this time, the linkage frame and the mounting column will move downward accordingly, and drive the top structure to move downward synchronously until the three coils enter the cleaning tank, the paint dipping tank, and the curing tank respectively. At this time, the coil to be cleaned will enter the cleaning tank, and the first motor can be turned on to drive the transmission shaft to rotate. At this time, the sun gear will rotate accordingly, and drive multiple planetary gears to rotate synchronously, that is, drive multiple clamping assemblies at the bottom to rotate synchronously, that is, drive the coils to rotate synchronously. At this time, the coil located inside the cleaning tank will rotate relative to the clean water, and the cleaning process is completed.

[0020] By utilizing the cooperation between the transmission component and multiple clamping components, and by setting a cleaning tank, a paint dipping tank, and a curing tank respectively corresponding to the cleaning, paint dipping, and curing of the coil, the coil can enter the interior of the cleaning tank before dipping, and the contact between the coil and clean water can be quickly achieved through the action of the transmission component to complete the self-cleaning process. The entire process can be automatically completed before dipping, without the need for manual cleaning of traditional devices, thereby significantly improving the dipping efficiency.

[0021] When the cleaning is completed, the electric push rod can be controlled to extend so that the cleaned coil leaves the interior of the cleaning tank, and the first motor is kept in a working state, that is, the multiple planetary gears are kept in a rotating state. At this time, the multiple clamping components at the bottom are still kept in a rotating state, so that the clean water on the surface of the cleaned coil can be dried. At the same time, the cleaned coil can be controlled to enter the interior of the curing tank, and the electric heating tube inside the curing tank is turned on to pre-dry the coil to remove moisture in the coil and ensure that the coil is in a dry state;

[0022] The cleaned coil can enter the interior of the paint dipping tank as the clamping assembly descends, and the rotation of the clamping assembly allows the cleaned coil to be in close contact with the insulating paint, so that the insulating paint completely covers the surface of the coil, completing the paint dipping operation.

[0023] By reusing the power transmission process of the transmission component, and through the cooperation between the cleaning tank and the paint dipping tank and the clamping action of the clamping component, the coil can be quickly dipped in paint after completing self-cleaning, and the insulating paint can be in uniform contact with the coil, so that the insulating paint completely covers the surface of the coil, ensuring the uniformity of the paint dipping and significantly improving the quality of the paint dipping.

[0024] When the coil is cleaned, the electric push rod extends, and the multiple clamping components rise accordingly. At this time, the second motor can be turned on to drive the linkage frame to rotate. At this time, the mounting column rotates accordingly, and drives the multiple planetary gears to rotate circumferentially with the sun gear as the center, until the cleaned coil enters the top of the paint dipping tank;

[0025] After the coil is dipped in paint and the clamping assembly rises, continue to drive the planetary wheel to rotate circumferentially until the coil after dipped in paint enters directly above the curing tank. Repeat the cleaning and dip-painting steps to evenly heat the insulating paint on the surface of the coil through the electric heating tube inside the curing tank to complete the curing operation. After curing is completed, take out the coil after dipped in paint.

[0026] Through the further utilization of the transmission components and multiple clamping components as well as the cleaning tank, the paint dipping tank and the curing tank, the coils can be automatically cleaned, dipped in paint and cured, and the whole process is completed automatically. At the same time, multiple coils can be cleaned, dipped in paint and cured at the same time. There is no need to wait during the whole process, which effectively shortens the waiting time in batch processing, simplifies the processing steps, shortens the processing time and improves the overall processing efficiency.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. The present invention utilizes the cooperation between the transmission component and multiple clamping components, and sets a cleaning tank, a paint dipping tank, and a curing tank to correspond to the cleaning, paint dipping, and curing of the coil respectively, so that the coil can enter the interior of the cleaning tank before dipping, and the contact between the coil and clean water is quickly achieved through the action of the transmission component to complete the self-cleaning process. The entire process can be automatically completed before dipping, without the need for manual cleaning of traditional devices, thereby significantly improving the dipping efficiency.

[0029] 2. The present invention reuses the power transmission process of the transmission component, and through the cooperation between the cleaning tank and the paint dipping tank and the clamping action of the clamping component, the coil can be quickly dipped in paint after completing self-cleaning, and the insulating paint can be in uniform contact with the coil, so that the insulating paint completely covers the surface of the coil, ensuring the uniformity of the paint dipping and significantly improving the quality of the paint dipping.

[0030] 3. The present invention further utilizes the transmission component and multiple clamping components as well as the cleaning tank, paint dipping tank, and curing tank, so that the coil can be automatically cleaned, dipped in paint, and cured. The entire process is completed automatically. At the same time, multiple coils can be cleaned, dipped in paint, and cured at the same time. There is no need to wait during the entire process, which effectively shortens the waiting time in batch processing, simplifies the processing steps, shortens the processing time, and improves the overall processing efficiency.

[0050] Embodiment: Before paint dipping, after the three coils are clamped and fixed with the three clamping assemblies 17 in turn, the electric push rod 12 can be turned on and controlled to shorten. At this time, the linkage frame 13 and the mounting column 14 move downward accordingly, and drive the top structure to move downward synchronously, until the three coils enter the cleaning tank 3, the paint dipping tank 4, and the curing tank 5 respectively. At this time, the coil to be cleaned enters the cleaning tank 3, and the first motor 10 can be turned on to drive the transmission shaft 9 to rotate.

The entire process can be automatically completed before dipping in paint, without the need for manual cleaning of traditional devices, thereby significantly improving the efficiency of dipping in paint.

[0052] Embodiment: After the cleaning is completed, the electric push rod 12 can be controlled to extend so that the cleaned coil leaves the interior of the cleaning tank 3, and the first motor 10 is kept in a working state, that is, the multiple planetary gears 113 are kept in a rotating state.

[0058] Working principle and usage process:

[0059] In the initial state, the electric push rod 12 is in the longest extension state, that is, the linkage frame 13 is at the highest point. At this time, the multiple clamping components 17 are all at the highest point, and the coils that need to be dipped in paint are ready. At the same time, it is necessary to ensure that the clean water and insulating paint inside the cleaning tank 3 and the dip paint tank 4 are in sufficient state. At the same time, the liquid level of the clean water and the insulating paint should be kept within a reasonable range to avoid splashing during use, and the preparation work before dipping in paint is completed;

[0060] In the initial state, that is, when the coil is not clamped, the electromagnet 161 is not started, and the limit spring 164 is in the initial state, that is, the permanent magnet 165 is at the lowest point, the limit spring 164 is also at the lowest point, and the clamping assembly 17 is also in the pre-clamping state;

[0061] When the coil is dipped in paint, the electromagnet 161 can be turned on, and the electromagnet 161 can generate suction force on the permanent magnet 165, and drive the permanent magnet 165 to move upward. At this time, the limit spring 164 can be stretched, and at the same time drive the movable rod 162 and the movable plate 163 to move upward, and act on the clamping assembly 17;

[0062] When the movable plate 163 moves upward, the connecting rod 177 can be synchronously driven to deflect, and the multiple connecting rods 177 can deflect toward the middle, and at the same time pull the limit block 173 to move toward the direction of the movable plate 163, and the multiple clamping plates 176 are relatively close to each other, and the coil can be placed at the position between the multiple clamping plates 176 until the multiple clamping plates 176 contact the outer side of the coil, and the clamping process of the coil is completed;

[0063] Before immersing in paint, after the three coils are clamped and fixed to the three clamping assemblies 17 in turn, the electric push rod 12 can be turned on and controlled to shorten. At this time, the linkage frame 13 and the mounting column 14 move downward accordingly, and drive the top structure to move downward synchronously, until the three coils enter the cleaning tank 3, the immersion tank 4, and the curing tank 5 respectively. At this time, the coil to be cleaned enters the cleaning tank 3, and the first motor 10 can be turned on to drive the transmission shaft 9 to rotate. At this time, the sun gear 114 rotates accordingly, and drives the multiple planetary gears 113 to rotate synchronously, that is, drives the multiple clamping assemblies 17 at the bottom to rotate synchronously, that is, drives the coils to rotate synchronously. At this time, the coil located inside the cleaning tank 3 rotates relative to the clean water, and the cleaning process is completed;

[0064] When the cleaning is completed, the electric push rod 12 can be controlled to extend so that the cleaned coil leaves the interior of the cleaning tank 3, and the first motor 10 is kept in a working state, that is, the multiple planetary gears 113 are kept in a rotating state. At this time, the multiple clamping components 17 at the bottom are still kept in a rotating state, so that the clean water on the surface of the cleaned coil can be dried. At the same time, the cleaned coil can be controlled to enter the interior of the curing tank 5, and the electric heating tube inside the curing tank 5 is turned on to pre-dry the coil to remove moisture in the coil and ensure that the coil is in a dry state;

[0065] The cleaned coil can enter the interior of the varnish dipping tank 4 as the clamping assembly 17 descends, and the cleaned coil is closely contacted with the insulating varnish through the rotation of the clamping assembly 17, so that the insulating varnish completely covers the surface of the coil, completing the varnish dipping operation;

[0066] When the coil is cleaned, the electric push rod 12 is extended, and the multiple clamping components 17 rise accordingly. At this time, the second motor 15 can be turned on to drive the linkage frame 13 to rotate. At this time, the mounting column 14 rotates accordingly, and drives the multiple planetary gears 113 to rotate circumferentially with the sun gear 114 as the center, until the cleaned coil enters the top of the paint dipping tank 4;

[0067] After the paint dipping of the coil is completed and the clamping assembly 17 rises, continue to drive the planetary gear 113 to rotate circumferentially until the paint-dipped coil enters directly above the curing tank 5. Repeat the cleaning and paint dipping steps to evenly heat the insulating paint on the surface of the coil through the electric heating tube inside the curing tank 5 to complete the curing operation. After curing is completed, take out the paint-dipped coil.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
