Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to an impregnation device for aluminum electrolytic capacitors. Background Technology

[0002] The impregnating agent for capacitors is an insulating liquid and a major material in capacitor production. As a liquid insulating medium, it fills the gaps between solid dielectrics and improves insulation strength. The performance of this structure under high electric fields determines the lifespan of the capacitor. Nowadays, capacitor cores are mostly impregnated in an impregnation tank. During impregnation, the cores are poured into an impregnation frame, the impregnation frame is placed into the impregnation tank, and then pressure is applied for impregnation. Since the cores are piled up in the impregnation frame, a special residual liquid tank is needed to filter out the residual liquid after impregnation using this method. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an aluminum electrolytic capacitor impregnation device with reasonable structure, good performance and fast impregnation speed.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: an impregnation device for aluminum electrolytic capacitors, comprising a core conveying tray, two tilting supports installed at the outlet of the core conveying tray, a tilting motor installed on the top of one tilting support, a synchronous bearing seat installed on the top of the other tilting support, a synchronous rail installed between the drive shaft of the tilting motor and the synchronous bearing seat, the synchronous rails being two parallel rails, the ends of the two synchronous rails being connected by a tilting tray, one tilting tray being connected to the drive shaft of the tilting motor, a synchronous shaft being provided on the outer side of the other tilting tray, the synchronous shaft being fitted inside the synchronous bearing seat, a clamping plate being installed on the tilting tray, an impregnation stage being installed below the clamping plate, a lifting cylinder being installed on the top of the impregnation stage, and an impregnation unit being installed on the top of the lifting cylinder.

[0005] The impregnation unit includes an impregnation tank and a liquid storage tank. The liquid storage tank is installed on the top of the lifting cylinder. A heating plate is installed on the top of the liquid storage tank. The impregnation tank is installed on the top of the heating plate. The opening at the top of the impregnation tank forms a clamping plate inlet. A liquid guide pipe is provided at the bottom of the impregnation tank. The bottom of the liquid guide pipe extends downward into the liquid storage tank. Air guide pipes are provided on both sides of the impregnation tank.

[0006] After adopting the above-mentioned solution, the core conveying disc vibrates, arranging the cores onto the clamping plate until the entire clamping plate is filled. After the plate is filled, the flipping motor drives the clamping plate to flip, and the clamping plate filled with cores flips downwards. The lifting cylinder drives the impregnation tank to rise and contact the clamping plate to form a seal. Electrolyte is injected into the impregnation tank through the liquid guide pipe to impregnate the cores. The structure of this solution is reasonable, the use effect is good, and the impregnation speed is fast. Attached Figure Description

[0009] The present invention will be further described below with reference to all the accompanying drawings. A preferred embodiment of the present invention is shown in the accompanying drawings. Figure 1 and appendix Figure 2 The aluminum electrolytic capacitor impregnation device described in this embodiment includes a core conveying tray 1. Two tilting supports are installed at the outlet of the core conveying tray 1. A tilting motor 21 is installed on the top of one tilting support, and a synchronous bearing seat is installed on the top of the other tilting support. A synchronous rail 22 is installed between the drive shaft of the tilting motor 21 and the synchronous bearing seat. The synchronous rails 22 are two parallel rails, and the ends of the two synchronous rails 22 are connected by a tilting tray 23. One tilting tray 23 is connected to the drive shaft of the tilting motor 21, and a synchronous shaft is provided on the outer side of the other tilting tray 23. The synchronous shaft is fitted into the synchronous bearing seat. A clamping plate 5 is installed on the tilting tray 23, and an impregnation table 2 is installed below the clamping plate 5. A lifting cylinder 6 is installed on the top of the impregnation table 2, and an impregnation unit is installed on the top of the lifting cylinder 6.

[0010] The impregnation unit includes an impregnation tank 18 and a liquid storage tank 19. The liquid storage tank 19 is installed on the top of the lifting cylinder 6. A heating plate 20 is installed on the top of the liquid storage tank 19. The impregnation tank 18 is installed on the top of the heating plate 20. The top opening of the impregnation tank 18 forms a clamping plate inlet. A liquid guide pipe 29 is provided at the bottom of the impregnation tank 18. The bottom of the liquid guide pipe 29 extends downward into the liquid storage tank 19. Air guide pipes 30 are provided on both sides of the impregnation tank 18.

[0011] The core conveyor vibrates, arranging the cores onto the clamping plate. The rotating motor rotates, driving the rotating pallet to rotate 180 degrees via the drive shaft. During the rotation, the rotating pallet simultaneously rotates the core pallet, core clamping plate, and other components 180 degrees, so that the core clamping plate filled with cores is rotated to the bottom of the synchronous rail (at this time, the core body is vertically downward, and the pins are inserted into the core clamping plate). When the core clamping plate filled with cores is at the bottom of the synchronous rail, the piston rod of the lifting cylinder extends, driving the impregnation tank, liquid storage tank, and other components to rise. The top of the impregnation tank contacts the bottom of the core pallet at the bottom of the synchronous rail to form a seal, and the core clamping plate containing the cores at the bottom of the core pallet is located inside the impregnation tank.

[0012] The control valve on the gas venting pipe is opened, the heating plate heats up, and the liquid venting pipe sends the electrolyte from the storage tank into the impregnation tank. The air in the impregnation tank is gradually discharged as the electrolyte is injected. When the electrolyte completely covers the core, the control valve on the gas venting pipe is closed, and electrolyte continues to be injected into the impregnation tank to compress the electrolyte. When the injected electrolyte reaches the set pressure value, the liquid control valve on the liquid venting pipe is closed, and the heating plate continues to heat up, creating a high-temperature and high-pressure environment in the impregnation tank, so that the electrolyte quickly impregnates the core, completing the impregnation of the capacitor core.

[0013] After impregnation, the liquid control valve on the liquid guide pipe and the control valve on the air guide pipe are opened, and air enters the impregnation tank. Without liquid supply, the electrolyte in the impregnation tank falls into the storage tank under its own weight and pressure relief, while the excess electrolyte (residual liquid) remaining on the core drips off, thus completing the impregnation. This solution uses high temperature and high pressure for impregnation, which has an extremely fast impregnation speed and can greatly shorten the preparation time of the capacitor. Moreover, the end of the core is not blocked during impregnation, resulting in a good impregnation effect. After impregnation, the residual liquid is directly filtered out in the impregnation tank, and the capacitor is directly picked up and put into the next process. There is no need to vibrate and discharge the material again, which saves space and equipment.

[0014] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all changes made in accordance with the shape and principle of this utility model should be covered within the protection scope of this utility model.
