Description

Technical Field

[0001] This utility model relates to the field of capacitor processing equipment, and in particular to a mica capacitor impregnation processing equipment. Background Technology

[0002] Mica capacitors are capacitors that use natural mica as the dielectric material. They are typically cube-shaped and offer excellent voltage withstand performance. A mica capacitor consists of coiled electrodes and a dielectric (insulating medium), with the electrodes serving as plates. These two materials are processed using a spool. After winding, the mica capacitor undergoes a vacuum impregnation process, which is crucial for achieving the "dry-type" structure of the mica capacitor.

[0003] Traditional impregnation fixtures for mica capacitors are extremely simple; they consist of an impregnation box in which the mica capacitors are arranged in an array. The impregnation box containing multiple mica capacitors is then placed into the impregnation chamber to begin the impregnation process.

[0004] However, in actual impregnation processing, the following technical problems were found in the existing impregnation processing equipment:

[0005] Existing impregnation processing equipment requires workers to reach inside the device to handle the impregnated capacitors. This process is inconvenient and poses safety hazards. Furthermore, existing impregnation processing equipment lacks a fixed positioning structure for the capacitors during impregnation, which can easily cause the mica capacitor leads to bend. After impregnation, manually straightening the leads may damage or misalign them, thus affecting the impregnation effect at the contact points and the product quality.

[0006] Therefore, in view of the fact that existing impregnation processing equipment requires workers to reach inside when handling capacitors, which is inconvenient and poses safety hazards; at the same time, the lack of a fixed positioning structure for the capacitors during the impregnation process causes the leads of the mica capacitors to be easily bent, a mica capacitor impregnation processing equipment that solves the above problems is needed. Utility Model Content

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A mica capacitor impregnation processing device includes a housing, a sealing cover rotatably connected to the top of the housing, a heating plate fixedly connected to the inner wall of the housing, and an inner liner fixedly connected to the inner wall of the heating plate.

Two connecting rods are fixedly connected to the top and bottom of the side plate on adjacent sides. A lifting rod is fixedly connected to the middle of the side of the top connecting rod. A limit groove is formed at the top outer side of the slider. A [missing information - likely a design feature] is formed inside the front top of the housing. The inner chamber has a gear rotatably connected to the bottom of its inner wall, and a knob fixedly connected to the top of the gear. The knob passes through the top of the casing. Horizontal grooves are provided on both the front and rear sides of the inner chamber. A rack is slidably connected to the inner wall of each horizontal groove. A movable groove one is provided at the right end of the rear side of the inner wall of the rear horizontal groove, and a movable groove two is provided at the left end of the rear side of the inner wall of the front horizontal groove. Slide plates are installed inside both movable groove one and movable groove two. The front end of the slide plate is fixedly connected to the rear side of the rack at a distance. A limit block is fixedly connected to the rear end of the slide plate on the side closest to it. A base is fixedly connected to the bottom of the casing, and a liquid outlet is provided at the bottom of the inner liner.

[0010] As a further improvement of this utility model, a plurality of mounting grooves are provided on the side of the side plate, and mounting plates are detachably connected to the inner walls of the plurality of mounting grooves. A plurality of fixing blocks are fixedly connected to the side of the side plate, and the fixing blocks are connected to the mounting plates through fixing components.

[0012] As a further improvement of this utility model, both the fixed clamping plate and the movable clamping plate are fixedly connected to an abutment block on their adjacent sides, and the adjacent side of the abutment block is in contact with the outer side of the workpiece.

[0013] As a further improvement of this utility model, the fixing component includes a through hole and a positioning hole. The through hole is opened on the top of the fixing block, and the positioning hole is opened on the front part of the left and right ends of the top side of the mounting plate. A positioning bolt is detachably connected inside the through hole, and the bottom end of the positioning bolt passes through the positioning hole.

[0014] As a further improvement of this utility model, the size of the limiting block is adapted to the limiting groove.

[0015] As a further improvement of this utility model, an inlet pipe is fixedly connected to the rear side of the inner wall of the inner liner, and the rear end of the inlet pipe penetrates the inner liner.

[0016] As a further improvement of this utility model, the top of the sealing cover is provided with an observation window, the side plate is L-shaped, and the rear side of the inner wall of the side plate is attached to the rear side of the mounting plate.

This completely avoids having to reach into the device, greatly improving the ease of operation and safety.

[0019] 2. This invention allows for flexible adjustment based on the different sizes and quantities of mica capacitors, significantly increasing the number of capacitors that can be impregnated at one time and improving production efficiency. Furthermore, through the coordinated action of the fixed clamp, sliding rod, movable clamp, and spring, the mica capacitors are securely clamped, preventing them from shaking or shifting during impregnation. This effectively avoids bending of the leads, ensuring the uniformity and stability of the impregnation process and significantly improving product quality. Attached Figure Description

[0036] Example 1: As Figure 1 , Figure 3 and Figure 4 As shown, a mica capacitor impregnation processing device includes a housing 1, a sealing cover 2 rotatably connected to the top of the housing 1, a heating plate 5 fixedly connected to the inner wall of the housing 1, an inner liner 6 fixedly connected to the inner wall of the heating plate 5, a sliding groove 7 formed at the middle of the left and right sides of the inner wall of the inner liner 6, a through groove 17 formed at the top of the inner wall of the sliding groove 7, a slider 8 detachably connected inside the sliding groove 7, a side plate 9 connected to the through groove 17 via the slider 8, two connecting rods 10 fixedly connected to the top and bottom ends of the side plate 9 on the adjacent side, a lifting rod 11 fixedly connected to the middle of the adjacent side of the top connecting rod 10, a limit groove 20 formed at the top of the outer side of the slider 8, and an inner cavity 12 formed inside the front end of the top side of the housing 1. A gear 13 is rotatably connected to the bottom side of the inner wall of the chamber 12. A knob 14 is fixedly connected to the top of the gear 13. The knob 14 passes through the top side of the casing 1. Horizontal grooves 15 are provided on both the front and rear sides of the inner chamber 12. A rack 16 is slidably connected to the inner wall of the horizontal groove 15. A movable groove 34 is provided at the right end of the rear side of the inner wall of the rear horizontal groove 15. A movable groove 35 is provided at the left end of the rear side of the inner wall of the front horizontal groove 15. Slide plates 18 are installed inside both movable grooves 14 and movable groove 35. The front end of the slide plate 18 is fixedly connected to the rear side of the rack 16 by a certain distance. A limit block 19 is fixedly connected to the rear end of the slide plate 18 on the side close to it. A base 4 is fixedly connected to the bottom of the casing 1. A liquid outlet 21 is provided at the bottom of the inner liner 6.

[0037] Specifically, the heating plate 5 fixedly connected to the inner wall of the casing 1 can heat the internal environment, promoting better penetration of the impregnation liquid into the mica capacitor. The sliding groove 7 opened at the middle of the left and right sides of the inner wall of the inner liner 6, together with the detachably connected slider 8, allows for convenient installation and removal of the side plate 9. The side plate 9 is connected to the slider 8 through the connecting rod 10 and the lifting rod 11. When it is necessary to remove the side plate 9 and the mica capacitor placed on it, it can be easily achieved by lifting the lifting rod 11 and using the slider 8 to slide in the sliding groove 7. The operation is convenient and avoids the safety hazards and impact on product quality caused by directly reaching into the inner liner 6. When the side plate 9 moves up and down, the related structure will move accordingly. Specifically, the side plate 9 is connected to the through groove 17 through the slider 8, and the upper outer end of the slider 8 has a limiting groove 20. In the inner cavity 12 inside the front top of the casing 1, the gear 13 rotates, driving the rack 16 to slide, thereby driving the slide plate 18 and the limiting block 19 connected to it to move. The presence of the through groove 17 allows the limiting block 19 to smoothly engage with the limiting groove 20 at the appropriate time during the up-and-down movement of the side plate 9, achieving precise positioning of the slider 8, effectively preventing the slider 8 from sliding accidentally, ensuring the stability of the side plate 9 during the immersion process, and through this mechanical structure, the position of the side plate 9 can be precisely controlled, improving the accuracy and reliability of the operation.

[0038] Example 2: As Figure 2 , Figure 3 and Figure 6 As shown, multiple mounting slots 23 are provided on the side of the side plate 9, and mounting plates 25 are detachably connected to the inner walls of the multiple mounting slots 23. Multiple fixing blocks 24 are fixedly connected to the side of the side plate 9, and the fixing blocks 24 are connected to the mounting plates 25 through fixing components 26. Multiple sliding grooves 27 are provided on the top of the mounting plate 25, and a machined part 33 is installed inside the sliding grooves 27. Multiple fixing clamps 29 are fixedly connected to the inner walls of the sliding grooves 27. Sliding rods 28 are fixedly connected to the left and right sides of the inner walls of the sliding grooves 27. Movable clamps 30 are slidably connected to the outer sides of the sliding rods 28. A spring 31 is fixedly connected to the rear side of the movable clamps 30. Abutment blocks 32 are fixedly connected to the side of the fixed clamps 29 and the movable clamps 30, and the side of the abutment blocks 32 is in contact with the outer side of the machined part 33. The fixing component 26 includes a through hole 2601 and a positioning hole 2602. The through hole 2601 is located on the top of the fixing block 24, and the positioning hole 2602 is located on the front part of the left and right ends of the top side of the mounting plate 25. A positioning bolt 2603 is detachably connected inside the through hole 2601, and the bottom end of the positioning bolt 2603 passes through the positioning hole 2602. The size of the limiting block 19 is adapted to the limiting groove 20. A liquid inlet pipe 22 is fixedly connected to the rear side of the inner wall of the inner liner 6, and the rear end of the liquid inlet pipe 22 passes through the inner liner 6. An observation window 3 is provided on the top of the sealing cover 2. The side plate 9 is L-shaped, and the rear side of the inner wall of the side plate 9 fits against the rear side of the mounting plate 25.

[0039] Specifically, multiple mounting slots 23 and a detachably connected mounting plate 25 are provided on the side of the side plate 9, allowing for flexible adjustment according to the different sizes and quantities of mica capacitors. The fixing block 24 is connected to the mounting plate 25 through the fixing component 26. The positioning bolt 2603 passes through the through hole 2601 and engages with the positioning hole 2602, ensuring that the mounting plate 25 is securely installed and can be disassembled and replaced according to actual needs, increasing the versatility of the device. Multiple sliding grooves 27 are provided on the top of the mounting plate 25, and the processed parts 33 are installed inside. Together with the fixed clamping plate 29, the movable clamping plate 30, and the spring 31, when the mica capacitor is placed in the sliding groove 27, the spring 31 pushes the movable clamping plate 30 towards the fixed clamping plate 29, and the abutment block 32 firmly clamps the mica capacitor, preventing the capacitor from shaking or shifting during the impregnation process, ensuring the uniformity and stability of the impregnation, and improving product quality. The inlet pipe 22, fixedly connected to the rear side of the inner wall of the inner liner 6, allows for precise injection of impregnation liquid into the inner liner 6, ensuring a stable supply of impregnation liquid. The observation window 3 on the top of the sealing cover 2 allows operators to observe the impregnation status inside the device in real time and keep track of the impregnation process. The L-shaped design of the side plate 9 allows it to better fit with the inner liner 6 and the mounting plate 25, ensuring structural stability and ease of installation.

[0040] Working principle: During operation, first open the sealing cover 2, rotate the knob 14 to make the gear 13 drive the rack 16, thereby moving the slide plate 18 and the limiting block 19, so that the limiting block 19 leaves the limiting groove 20. Pull the lifting rod 11 to slide the side plate 9 out through the slider 8 in the first slide groove 7. According to the size and quantity of the mica capacitor, install the appropriate mounting plate 25 in the mounting groove 23 of the side plate 9, and fix it with the positioning bolt 2603 through the through hole 2601 and the positioning hole 2602. Place the mica capacitor in the second slide groove 27 of the mounting plate 25, and spring 31. Push the movable clamping plate 30 to cooperate with the fixed clamping plate 29 to clamp the capacitor through the abutment block 32, then put the side plate 9 back into the inner liner 6 through the slider 8, turn the knob 14 to make the limiting block 19 lock into the limiting groove 20 to fix the slider 8, close the sealing cover 2, inject the impregnation liquid into the inner liner 6 through the liquid inlet pipe 22, start the heating plate 5 to heat, and the operator observes the impregnation situation through the observation window 3. After the impregnation is completed, turn the knob 14 again to make the limiting block 19 leave the limiting groove 20, take out the side plate 9, and finally drain the impregnation liquid through the liquid outlet 21 at the bottom of the inner liner 6.
