[0014] A further technical improvement of the present invention is that an electric push rod 1 is installed on the bottom surface of the movable frame, a pushing end of the electric push rod 1 is connected to a connecting plate, and the connecting plate is fixed to two vertical plates.

[0015] A further technical improvement of the present invention is: a working method of a coil varnish dipping device for an electronic transformer, the working method comprising the following steps:

[0016] Step 1: Install several transformer coils between two connecting seats on a platform. During the installation process, the outer surface of the pad seat pushes the upper and lower moving blocks to move upward and downward respectively until the pad seat contacts the fixed block, and the fixed block and the two moving blocks position the pad seat;

[0017] Step 2: Then the mobile frame drives several coils to pass through the installation slot for cleaning. During the cleaning, the support rod enters the placement slot. When the main shaft rod rotates, the driven rod is reciprocated and lifted under the rotation of the eccentric gear and the driven rod, so that the surface of the coil is completely immersed in water. The electric push rod 2 pushes the cleaning sponge, and the raised part on the cleaning sponge rubs against the surfaces of the several coils that are lifting and lowering to remove dust and oil stains.

[0018] Step three, then move the coil to the preheating chamber for preheating. After preheating, the moving frame slides on a set of slide rails 1 until it reaches the top of the primary paint dipping chamber for paint dipping. After paint dipping, the slide rail 2 on one of the transmission plates moves to coincide with the end face of the slide rail 1. The coil slides onto the slide rail 2 via the slide rail 1, and one of the transmission plates slides longitudinally on the corresponding linear guide rail until the slide rail 2 on one of the transmission plates coincides with the end face of the other set of slide rails 1. The coil follows the sliding of the moving frame and enters the secondary paint dipping chamber and the secondary heat curing chamber in turn to complete the secondary paint dipping and secondary heat curing molding.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Before the coils in the present invention are dipped in paint, a cleaning step is first performed. Several coils enter the cleaning tank until the support rod fits with the bottom surface of the inner cavity of the placement tank, and half of the coil surface is stained with cleaning water. The cleaning sponge is pushed to one side by the electric push rod 2. At this time, the raised part of the cleaning sponge contacts the outer surface of several coils. Then the eccentric transmission component starts to rotate, so that the limiting component equipped with several coils is reciprocated and lifted. The coil rotates and moves downward, and the rotation makes the surface of the coil contact water. The downward movement makes the coil completely enter the water and fully contact the water in the cleaning tank. At the same time, several coils rub downward with the raised part of the cleaning sponge to scrape off the dust or oil on the surface of the coil, thereby improving the cleaning ability of the surface of several coils and improving the quality of the coil when dipped in paint;

[0021] 2. The coil wound with the pad seat is installed in the limiting component. Since the pad seat is circular and the limiting component adopts a horizontal design, the installation and removal of each coil do not affect each other, which improves efficiency. During installation, the two ends of the pad seat fit with the two connecting seats, which is convenient for the installation of the pad seat and the coil. The outer surface of the pad seat abuts against the two upper and lower moving blocks, so that the upper and lower moving blocks slide up and down on the connecting seat respectively until the outer surface of the pad seat abuts against the fixed block, and the sliding of the moving block stops. The top outer surface, bottom outer surface and one end outer surface of the pad seat are fixed by three friction plates. The remaining coils are installed in the same way to achieve rapid installation of several coils and ensure the stability of the coil during cleaning.

[0022] 3. A plurality of mobile racks are provided, and all of the mobile racks can slide on two sets of slide rails 1 and 2 to complete the secondary paint dipping operation, and the transmission plate equipped with the slide rail 2 slides longitudinally on the linear guide rail, so that the mobile rack can smoothly switch tracks between the two sets of slide rails 1, so that the mobile rack can circulate in the processing room, shortening the waiting time of the coils on the mobile rack during operation and improving work efficiency.

[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] See also Figure 1-Figure 6 As shown, the present invention provides a coil varnish dipping device for an electronic transformer, comprising a processing chamber 1, a partition 17 is vertically arranged in the middle of the inner cavity of the processing chamber 1, a cleaning chamber, a preheating chamber 13, a primary varnish dipping chamber 5 and a primary heat curing chamber 14 are arranged in sequence on one side of the partition 17, two sets of slide rails 1 21 are installed on the top of the inner cavity of the processing chamber 1, both sides of the slide rails 1 21 are provided with longitudinally arranged linear guide rails 22, each linear guide rail 22 is slidably provided with a transmission plate 23, the bottom surface of the transmission plate 23 is provided with a slide rail 24 arranged flush with the end of the slide rail 1 21, and the outer surface of the slide rail 24 A moving frame 3 is slidably installed, and a plurality of moving frames 3 are provided. A limiting assembly for installing a plurality of coils is provided below the moving frame 3. A pad seat 7 is provided inside each coil. The limiting assembly includes two vertical plates 61, and an eccentric transmission assembly for driving a plurality of coils to reciprocate and lift is fitted above the limiting assembly. The cleaning chamber includes a mounting groove 4, and a cleaning groove 43 is provided inside the mounting groove 4. A placement groove 44 is provided on the top surface of the cleaning groove 43. A support rod 66 is fixed on the side of the vertical plate 61 away from the driven rod 65, and the support rod 66 is fitted with the upper surface of the placement groove 44.

[0033] An electric push rod 2 41 is installed on the inner wall surface of the cleaning tank 43, and a cleaning sponge 42 is fixedly connected to the pushing end of the electric push rod 2 41. The surface of the cleaning sponge 42 is provided with a plurality of protrusions that contact the corresponding coil surfaces. First, a plurality of coils are installed in the limiting component, and are driven by a set of slide rails 21 to enter the cleaning chamber, the preheating chamber 13 and the primary immersion paint chamber 5 in sequence. During the cleaning operation, a plurality of coils enter the cleaning tank 43 until the support rod 66 fits with the bottom surface of the inner cavity of the placement tank 44. At this time, only half of the coil surface is contaminated with cleaning water. The cleaning sponge 42 is pushed to one side by the electric push rod 2 41. At this time, the protrusion of the cleaning sponge 42 contacts the outer surface of the plurality of coils, and then the eccentric transmission component The rotation starts, so that the limiting component equipped with several coils is lifted and lowered reciprocatingly, and the coil rotates and moves downward, so that the surface of the coil contacts the water, and the downward movement makes the coil completely enter the water and fully contact the water in the cleaning tank 43. At the same time, several coils rub against the raised part of the cleaning sponge 42 downward to scrape off the dust or oil on the surface of the coil, thereby improving the cleaning ability of the surface of several coils and improving the paint dipping quality of the coil. When dipping in paint, the rotation of the eccentric transmission component is also used to make the limiting component lift and lower reciprocatingly, and the paint dipping effect is more complete. Afterwards, the movable frame 3 slides into the primary thermal curing chamber 14 by a set of slide rails 1 21 and slide rail 2 24, and the coils after dipping in paint are thermally cured to facilitate the curing of the paint layer and improve the insulation performance.

[0034] See also Figure 6 As shown, the surface of the connecting seat 652 is provided with a vacant groove, and the surface of the movable block 655 is installed with a wedge block sliding in the vacant groove, one end of the wedge block is fixedly connected to a compression spring 656, and one end of the compression spring 656 is fixed to the vacant groove. Initially, the length of the two movable blocks 655 is smaller than the diameter of the pad seat 7. When the pad seat 7 is installed, after the outer surface of the pad seat 7 contacts the side edges of the two movable blocks 655, the movable block 655 is subjected to a thrust. Under the thrust, the wedge block on the movable block 655 slides in the vacant groove and squeezes the compression spring 656. In this process, the outer surface of the pad seat 7 contacts the fixed block 654. At this time, the movable block 655 stops sliding with the connecting seat 652, and the friction plates on the movable block 655 and the fixed block 654 are used to clamp the outer surface of the pad seat 7, thereby fixing the coil, facilitating the cleaning of the coil and the stable operation of its paint dipping.

[0035] See also Figure 5 and Figure 6As shown, the eccentric transmission assembly includes a main shaft rod 6 rotatably installed between two vertical plates 61, a driven rod 65 is rotatably arranged below the main shaft rod 6, one end of the driven rod 65 is rotatably connected to a mounting seat 651, and the other end of the driven rod 65 is fixed to a connecting seat 652, the mounting seat 651 is slidably arranged with the vertical plate 61, and the outer surfaces of the main shaft rod 6 and the driven rod 65 are fixedly sleeved with an eccentric wheel 63 and an eccentric gear 64, the two eccentric wheels 63 are in close contact, the two eccentric gears 64 are meshed, two fixed rods 653 are arranged between two adjacent connecting seats 652, and the fixed block 654 is located between the two fixed rods 653. When cleaning and varnishing, the two vertical plates 61 enter the cleaning The driven rod 65 rotates with the mounting seat 651 under the action of the two eccentric wheels 63 and the two eccentric gears 64. When the main shaft 6 rotates, the driven rod 65 rotates while driving the mounting seat 651 downward along the vertical plate 61. When the main shaft 6 rotates 180 degrees, the driven rod 65 drops to the lowest position, and the pad seat 7 drives the coil to drop in height after being positioned, so that the coil can be cleaned and dipped in paint more fully. Then, the driven rod 65 returns to its initial height after another 180 degrees rotation. One rotation is one movement cycle.

[0036] See also Figure 5 As shown, a sliding groove 611 is provided on one side surface of the bottom of the vertical plate 61 for sliding the mounting seat 651, and a compression spring 612 is connected to the bottom end of the mounting seat 651, and one end of the compression spring 612 is fixed to the sliding groove 611. When working, the compression spring 612 is used to elastically support the height of the driven rod 65 to avoid disengagement between the two eccentric gears 64. The mounting seat 651 slides in the sliding groove 611 and squeezes the compression spring 612. At this time, the two eccentric wheels 63 and the eccentric gears 64 maintain a state of contact and meshing.

[0037] See also Figure 4 , Figure 5 and Figure 6As shown, the limiting component also includes a plurality of connecting seats 652, and a fixed card block 654 is fixedly connected to the edge surface of the connecting seat 652. Two movable card blocks 655 are symmetrically arranged on one side of the fixed card block 654. The two movable card blocks 655 are both slidably arranged with the connecting seat 652. The fixed card block 654, the movable card block 655 and the pad seat 7 are at the same center of the circle, and the installation is precise. First, the coil wound with the pad seat 7 is installed in the limiting component. Since the pad seat 7 is circular, during installation, the two ends of the pad seat 7 are fitted with the two connecting seats 652, which is convenient for the installation of the pad seat 7 and the coil. The surfaces of block 655 and fixed block 654 are both provided with friction plates, and the outer surface of the pad seat 7 abuts against the upper and lower movable blocks 655, so that the upper and lower movable blocks 655 slide upward and downward respectively on the connecting seat 652 until the outer surface of the pad seat 7 abuts against the fixed block 654, and the sliding of the movable block 655 stops, and the top outer surface, bottom outer surface and one end outer surface of the pad seat 7 are fixed by three friction plates, and the remaining coils are installed in the same way to achieve rapid installation of several coils, ensuring the stability of the coils during cleaning and avoiding shaking.

[0038] See also Figure 1 and Figure 3 As shown, a secondary paint dipping chamber 15 and a secondary thermal curing chamber 16 are provided in sequence on the other side of the partition 17. The secondary paint dipping chamber 15 is connected with the primary thermal curing chamber 14. The inlet and outlet ends of the preheating chamber 13, the primary paint dipping chamber 5 and the secondary paint dipping chamber 15 are all equipped with a sealing plate 12 that performs a lifting movement. Two platforms 11 are provided on the side of the processing chamber 1 away from the primary thermal curing chamber 14. Several coils are first cleaned by the cleaning chamber to remove dirt and oil on the surface of the coils to ensure that the surface of the coils is clean. They are preheated by the preheating chamber 13 to help the paint to better penetrate and adhere to the coils. Then they enter the primary paint dipping chamber 5 for immersion. After being taken out, they stay just above the primary paint dipping chamber 5. After being fully drained of the remaining paint, they arrive at the primary thermal curing chamber 14, which helps the paint layer to cure and improve the insulation performance. The coils enter the secondary paint dipping chamber 15 again for immersion again to increase the thickness of the paint layer and protect the surface of the coils. Finally, they arrive at the secondary thermal curing chamber 16 for uniform thermal curing and are discharged from the platform 11.

[0039] See also Figure 1 As shown, an electric push rod 31 is installed on the bottom surface of the movable frame 3, and the pushing end of the electric push rod 31 is connected to a connecting plate 32, and the connecting plate 32 is fixed to two vertical plates 61. Through the extension of the electric push rod 31, the connecting plate 32, the limiting assembly and the eccentric transmission assembly are driven to descend together.

[0040] The present invention also provides a working method of a coil varnish dipping device for an electronic transformer, the working method comprising the following steps:

[0041] Step 1: On a platform 11, several transformer coils are installed between two connecting seats 652. During the installation process, the outer surface of the pad seat 7 pushes the upper and lower moving blocks 655 to move upward and downward respectively until the pad seat 7 contacts the fixed block 654. The fixed block 654 and the two moving blocks 655 position the pad seat 7.

[0042] Step 2: Then the moving frame 3 drives several coils to pass through the installation slot 4 for cleaning. During the cleaning, the support rod 66 enters the placement slot 44. When the main shaft rod 6 rotates, the driven rod 65 is reciprocated and lifted under the rotation of the eccentric gear 64 and the driven rod 65, so that the surface of the coil is completely immersed in water. The electric push rod 2 41 pushes the cleaning sponge 42, and the raised part on the cleaning sponge 42 is in friction contact with the surface of the several coils in the lifting motion to remove dust and oil stains.

[0043] Step three, then move the coil to the preheating chamber 13 for preheating. After preheating, the movable frame 3 slides on a set of slide rails 21 until it reaches the top of the primary paint dipping chamber 5 for paint dipping. After paint dipping, the slide rail 24 on one of the transmission plates 23 moves to coincide with the end face of the slide rail 21. The coil slides to the slide rail 24 via the slide rail 1 21, and one of the transmission plates 23 slides on the corresponding linear guide rail 22. At this time, the slide rail 24 coincides with the end face of the other set of slide rails 21. The coil follows the sliding of the movable frame 3 and enters the secondary paint dipping chamber 15 and the secondary thermal curing chamber 16 in turn to complete the secondary paint dipping and secondary thermal curing molding.

[0044] When the present invention is in use, firstly, the coil wound with the pad seat 7 is installed in the limiting component. Since the pad seat 7 is circular, during installation, the two ends of the pad seat 7 are fitted with the two connecting seats 652, which is convenient for the installation of the pad seat 7 and the coil. The outer surface of the pad seat 7 abuts against the two upper and lower moving blocks 655, so that the upper and lower moving blocks 655 slide upward and downward on the connecting seat 652 respectively until the outer surface of the pad seat 7 abuts against the fixed block 654, and the moving block 655 stops sliding. The top outer surface, the bottom outer surface and the outer surface of one end of the pad seat 7 are fixed by three friction plates. The remaining coils are installed in the same way to achieve rapid installation of several coils and ensure the stability of the coils during cleaning.

[0045] During cleaning, several coils enter the cleaning tank 43 until the support rod 66 fits with the bottom surface of the inner cavity of the placement tank 44, and half of the coil surface is stained with cleaning water. The electric push rod 41 pushes the cleaning sponge 42 to move to one side. At this time, the raised part of the cleaning sponge 42 contacts the outer surface of several coils. Then the eccentric transmission component starts to rotate, so that the limiting component equipped with several coils is lifted and lowered back and forth, and the coil rotates and moves downward. The rotation makes the coil surface contact water, and the downward movement makes the coil completely enter the water and fully contact the water in the cleaning tank 43. At the same time, several coils rub downward with the raised part of the cleaning sponge 42 to scrape off the dust or oil on the coil surface, thereby improving the cleaning ability of the surfaces of several coils and improving the coating quality of the coils.

[0046] A plurality of movable racks 3 are provided, and all of the movable racks 3 can slide on two sets of slide rails 1 21 and slide rails 24 to complete the secondary paint dipping operation, and a transmission plate 23 equipped with slide rails 24 slides longitudinally on the linear guide rail 22, so that the movable rack 3 can smoothly switch tracks between the two sets of slide rails 1 21, so that the movable rack 3 can circulate in the processing chamber 1, shortening the waiting time of the coils on the movable rack 3 during operation and improving work efficiency.

6. The coil varnish dipping device of an electronic transformer according to claim 5, characterized in that: An electric push rod 1 (31) is installed on the bottom surface of the moving frame (3), and a pushing end of the electric push rod 1 (31) is connected to a connecting plate (32), and the connecting plate (32) is fixed to two vertical plates (61).

7. The working method of the coil varnish dipping device of an electronic transformer according to any one of claim 6, characterized in that: The working method comprises the following steps: Step 1: On a platform (11), a plurality of transformer coils are installed between two connecting seats (652). During the installation process, the outer surface of the pad seat (7) pushes the upper and lower movable blocks (655) to move upward and downward respectively until the pad seat (7) contacts the fixed block (654), and the pad seat (7) is positioned by the fixed block (654) and the two movable blocks (655); Step 2: Then, the moving frame (3) drives a plurality of coils to pass through the installation slot (4) for cleaning. During the cleaning, the support rod (66) enters the placement slot (44). When the main shaft rod (6) rotates, the eccentric gear (64) and the driven rod (65) rotate, causing the driven rod (65) to reciprocate and rise and fall, so that the surface of the coil is completely immersed in water. The cleaning sponge (42) is pushed by the electric push rod (41), and the raised portion on the cleaning sponge (42) is in friction contact with the surface of the plurality of coils that are moving upward and downward, thereby removing dust and oil stains. Step 3, then move the coil to the preheating chamber (13) for preheating. After preheating, the moving frame (3) slides on a set of slide rails (21) until it reaches the top of the primary immersion chamber (5) for immersion. After immersion, the slide rail (24) on one of the transmission plates (23) moves to coincide with the end face of the slide rail (21). The coil slides via the slide rail (21) to the slide rail (24). One of the transmission plates (23) slides longitudinally on the corresponding linear guide rail (22) until the slide rail (24) on one of the transmission plates (23) coincides with the end face of the other set of slide rails (21). The coil follows the sliding of the moving frame (3) and enters the secondary immersion chamber (15) and the secondary heat curing chamber (16) in turn to complete the secondary immersion and secondary heat curing molding.
