Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, specifically to an impregnation fixture based on capacitor processing. Background Technology

[0002] Two conductors placed close together, with a non-conductive insulating medium sandwiched between them, constitute a capacitor. Capacitors are among the most widely used electronic components in electronic devices, extensively applied in circuits for DC blocking and AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. In capacitor manufacturing, the impregnation process is crucial, removing air and moisture from the core. The purpose of capacitor impregnation is to eliminate moisture and gases from the capacitor, followed by filling all voids between the solid components with a purified and tested impregnating agent to improve the product's electrical performance. Therefore, the quality of capacitor impregnation is closely related to the capacitor's performance.

[0003] The patent publication number CN112103101B discloses a capacitor impregnation device that can prevent capacitor leads from being impregnated, relating to the field of capacitor production. It includes a device body, a placement plate fixed to one end of the device body, a clamping mechanism installed at the top of the placement plate, a connecting box at the top of the device body, an electromagnet installed at the bottom of the connecting box, a second conductive block fixed to one side of the electromagnet, a feeding mechanism connected to the bottom of the second conductive block, and a load-bearing frame installed at the bottom of the feeding mechanism.

[0004] To address the cumbersome clamping method for capacitors during capacitor impregnation and the problem of impregnation solution adhering to the bottom of the clamps in the capacitor impregnation equipment, existing technology uses a device body, electromagnet, second conductive block, and feeding mechanism. The movement of the first and second moving plates causes the fixing holes to clamp the leads at the top of the capacitor. However, this method still results in the capacitor simply being immersed in the solution, requiring a long impregnation period to achieve the desired effect, leading to poor impregnation results and low impregnation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an impregnation fixture for capacitor processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An impregnation fixture for capacitor processing includes an impregnation mechanism. An air extraction mechanism is located on the left side of the impregnation mechanism, and a working mechanism is located on the top of the impregnation mechanism. The impregnation mechanism includes an impregnation tank with an internal cavity. Support legs are fixedly connected to the bottom perimeter of the impregnation tank, and connecting rods are fixedly connected to the top perimeter of the impregnation tank. Limit blocks are fixedly connected to the corners of the inner wall of the impregnation tank. A barrier net is movably installed inside the impregnation tank, positioned above the limit blocks, with its sidewalls slidably connected to the inner wall of the impregnation tank. Sealing grooves are formed on the top of the sidewalls of the impregnation tank. A drain pipe is fixedly connected to the center of the bottom of the impregnation tank, with one end extending through the bottom of the impregnation tank into the internal cavity. A control valve is fixedly installed at the center of the other end of the drain pipe. An operation box is fixedly connected to the top of the connecting rods, and an operation panel is provided on the front of the operation box. The impregnation time of the capacitor can be controlled via the operation panel, and the barrier net can prevent falling capacitors.

[0008] A further improvement of the present invention is that the air extraction mechanism includes a vacuum machine, and a bracket is fixedly connected to the bottom of the vacuum machine.

[0009] Using the above technical solution, the vacuum machine is an existing device, and the bracket is used to support the vacuum machine.

[0010] A further improvement of this utility model is that a connecting pipe is fixedly connected to the right side of the vacuum machine, one end of the connecting pipe extends into the interior of the vacuum machine, and the other end of the connecting pipe passes through the side wall of the impregnation tank and extends into the inner cavity.

[0011] Using the above technical solution, the connecting tube is used to evacuate the inside of the impregnation tank to a vacuum, thereby accelerating the impregnation efficiency of the capacitor.

[0012] A further improvement of this utility model is that the working mechanism includes a sealing cover plate, the side of which is slidably connected to the side wall of the connecting support rod, a sealing strip is fixedly installed around the bottom of the sealing cover plate, the position and size of the sealing strip are matched with the sealing groove, and a connecting rod is rotatably connected to the middle of the sealing cover plate.

[0013] Using the above technical solution, the sealing strip and the sealing groove work together to completely seal the immersion box, preventing air leakage during subsequent vacuuming.

[0014] A further improvement of this utility model is that: the bottom of the connecting rod is provided with a fixed thread, a storage tray is slidably connected to the bottom outer wall of the connecting rod, the storage tray is uniformly provided with liquid permeable holes, and a threaded hole is provided at the center of the storage tray.

[0015] Using the above technical solution, the tray is used to place the capacitor, and the liquid permeation hole ensures that the immersion solution enters the tray and makes full contact with the capacitor.

[0016] A further improvement of this utility model is that: the fixing thread passes through the threaded hole and is threaded to a fixing nut; the top of the connecting rod is fixedly connected to the output shaft of the rotating motor; and the bottom of the rotating motor is fixedly connected to the top of the sealing cover plate.

[0017] By adopting the above technical solution, the motor can drive the tray to rotate, which can accelerate the impregnation efficiency of the capacitor.

[0018] A further improvement of this utility model is that a pressure gauge is fixedly installed on the sealing cover, a hydraulic rod is fixedly installed on the top of the sealing cover, and the top of the hydraulic rod is fixedly connected to the bottom of the operating box.

[0019] Using the above technical solution, the internal pressure of the impregnation chamber can be observed through a pressure gauge to ensure the pressure during vacuuming.

[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0021] 1. This utility model provides an impregnation fixture based on capacitor processing. Through the design of the vacuum mechanism, when the capacitor is impregnated, the vacuum machine is started to first evacuate the inside of the impregnation tank, so that the capacitor is in a negative pressure state. Then the pressure is applied, so that the impregnation solution can fully penetrate the capacitor, which greatly improves the impregnation effect, significantly shortens the impregnation time, improves product quality, and enhances the performance of the capacitor.

[0022] 2. This utility model provides an impregnation fixture for capacitor processing. Through the design of the working mechanism, multiple capacitors can be placed in a tray simultaneously. The tray can also rotate during the impregnation process, effectively improving the impregnation material yield of the capacitors.

Before impregnation begins, the control valve 18 is closed, and the impregnation solution is poured into the inner cavity of the impregnation tank 11. The working mechanism 3 is moved by controlling the operation panel 191. After impregnation is completed, the control valve 18 is opened to discharge the waste liquid through the drain pipe 17. The screen 15 can block the falling capacitors, and at the same time, it can be observed whether there are any fallen capacitors on the screen 15 for easy removal.

When the capacitor is impregnated, the vacuum machine 21 is started to first evacuate the interior of the impregnation tank 11 through the connecting pipe 23, so that the capacitor is in a negative pressure state, and then pressurization is applied so that the impregnation solution comes into contact with the capacitor and fully impregnates the capacitor. During this period, the pressure inside the impregnation tank 11 can be ensured by observing the pressure gauge 36.

When the sealing cover plate 31 moves downward, the sealing strip 32 is inserted into the sealing groove 16 to seal the impregnation box 11. At the same time, the storage tray 34 and the connecting rotating rod 33 can be disassembled to facilitate the removal of the impregnated capacitor.

[0036] The working principle of this impregnation fixture based on capacitor processing will be explained in detail below.

[0037] like Figure 1-5As shown, first, place the capacitor inside the tray 34. Rotate the tray 34 to connect the threaded hole 342 with the fixing thread 331 at the lower end of the connecting rod 33. Then, use the fixing nut 343 to reinforce it. Control the hydraulic rod 37 through the operation panel 191 to move the sealing cover 31 downward. Insert the sealing strip 32 into the sealing groove 16 to seal the impregnation tank 11. Start the vacuum machine 21 to evacuate the impregnation tank 11 through the connecting pipe 23, so that the capacitor is in a negative pressure state. Then pressurize it and start the rotating motor 35 to drive the tray 34 to rotate, so that the impregnation solution passes through the liquid permeation hole 341 and comes into contact with the capacitor to fully impregnate the capacitor. After impregnation, open the control valve 18 through the operation panel 191 to discharge the waste liquid through the drain pipe 17. At the same time, control the hydraulic rod 37 to move the sealing cover 31 upward. Disconnect the tray 34 from the connecting rod 33 to remove the impregnated capacitor.
