As a liquid insulating medium, it fills the gaps between solid media and improves the insulation strength. The performance of this structure under a high electric field determines the life of the capacitor. Currently, the capacitor core is mostly impregnated through an impregnation kettle. During the impregnation, the core is poured into the impregnation frame, and the impregnation frame is placed in the impregnation kettle, and then pressurized for impregnation. Since the core is accumulated in the impregnation frame, a special residual liquid barrel is required to filter out the residual liquid after impregnation in this way. Summary of the invention

After the remaining liquid on the core drips off, the turning motor drives the core clamp to turn 180 degrees; Step 7: Take out the capacitor core after dipping.
[0005] During the impregnation in the fourth step, the control valve on the air duct is opened, the heating plate is heated, the liquid duct delivers the electrolyte in the liquid storage tank into the impregnation tank, and the air in the impregnation tank is gradually discharged as the electrolyte is injected; when the electrolyte completely covers the core body of the core, the control valve on the air duct is closed.

[0012] The present invention will be further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows: Figure 1 And attached Figure 2 The present embodiment provides a system for preparing an aluminum electrolytic capacitor core by impregnation, and the preparation system includes the following steps: The first step: arranging the capacitor core on the clamping plate by the conveying unit; Step 2: The flip motor drives the clamp to flip 180 degrees so that the core body of the core faces downward; The third step: the lifting cylinder pushes the impregnation box upward to contact the bottom of the core support plate, so that the core is located in the impregnation box; Step 4: injecting electrolyte into the impregnation box, the amount of electrolyte injected soaking the surface of the core; Step 5: Heating the electrolyte in the impregnation box, continuously injecting the electrolyte to make the pressure in the impregnation box reach a set value, so that a high temperature and high pressure state is formed in the impregnation box; Step 6: After the core is impregnated, the impregnation tank is depressurized to return the electrolyte to the liquid storage tank. After the remaining liquid on the core drips off, the turning motor drives the core clamp to turn 180 degrees; Step 7: Take out the capacitor core after dipping.
[0013] In the fourth step, during impregnation, the control valve on the air duct is opened, the heating plate is heated, the liquid duct sends the electrolyte in the liquid storage tank into the impregnation tank, and the air in the impregnation tank is gradually discharged with the injection of the electrolyte; when the electrolyte completely covers the core body of the core, the control valve on the air duct is closed.
[0014] In the fifth step, electrolyte is continuously injected into the impregnation box to compress the electrolyte. When the amount of electrolyte injected reaches the set pressure value, the liquid control valve on the liquid guide tube is closed. At the same time, the heating plate is continuously heated to form a high temperature and high pressure environment in the impregnation box, so that the electrolyte can be quickly impregnated into the core of the core to complete the impregnation of the capacitor core.
[0015] It includes a core conveying tray 1, two flipping pillars 20 are installed at the outlet of the core conveying tray 1, a flip motor 21 is installed on the top of one of the flipping pillars 20, a synchronous bearing seat is installed on the top of the other flipping pillar 20, a synchronous rail 22 is installed between the transmission shaft of the flipping motor 21 and the synchronous bearing seat, the synchronous rails 22 are two parallel, the ends of the two synchronous rails 22 are connected by a flipping support plate 23, one of the flipping support plates 23 is connected to the transmission shaft of the flipping motor 21, and a synchronous shaft is provided on the outer side of the other flipping support plate 23, the synchronous shaft is sleeved in the synchronous bearing seat, a clamping plate 5 is installed on the flipping support plate 23, 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. The impregnation unit includes an impregnation box 18 and a liquid storage tank 19, wherein 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, and the impregnation box 18 is installed on the top of the heating plate 20. The top opening of the impregnation box 18 forms a splint entrance; a liquid guide pipe 29 is provided at the bottom of the impregnation box 18, and the bottom of the liquid guide pipe 29 extends downward into the liquid storage tank 19, and air guide pipes 30 are provided on both sides of the impregnation box 18.
[0016] The core conveyor plate vibrates, and the cores are arranged on the splint. The turning motor rotates through the transmission shaft to drive the turning pallet to rotate 180 degrees. During the turning process, the turning pallet synchronously drives the core pallet, core splint and other components to turn 180 degrees, so that the core splint filled with cores is turned over and located at the bottom of the synchronous rail (at this time, the core body of the core is in a vertical downward state, and the pins are inserted in the core splint). When the splint filled with cores is at the bottom of the synchronous rail, the piston rod of the lifting cylinder extends to drive the impregnation box, liquid storage tank and other components to rise. The top of the impregnation box contacts the bottom of the core pallet at the bottom of the synchronous rail to form a seal, and the core splint with cores at the bottom of the core pallet is located in the impregnation box. The control valve on the air pipe is opened, the heating plate is heated, and the liquid pipe sends the electrolyte in the liquid storage tank into the impregnation box. The air in the impregnation box is gradually discharged as the electrolyte is injected. When the electrolyte completely covers the core body of the core, the control valve on the air pipe is closed, and the electrolyte is continuously injected into the impregnation box to form a compressed state of the electrolyte. When the injection amount of the electrolyte reaches the set pressure value, the liquid control valve on the liquid pipe is closed, and the heating plate is continuously heated at the same time, so that a high temperature and high pressure environment is formed in the impregnation box, so that the electrolyte is quickly impregnated into the core body of the core, and the impregnation of the capacitor core is completed. After the impregnation is completed, the liquid control valve on the liquid guide tube and the control valve on the air guide tube are opened, and air enters the impregnation box. In the case of no liquid supply, the electrolyte in the impregnation box falls into the liquid storage tank under its own weight and pressure relief, and at the same time, the excess electrolyte (residual liquid) left on the core is dripped, thereby completing the impregnation. This scheme adopts high temperature and high pressure for impregnation, and its impregnation speed is extremely fast, which can greatly shorten the preparation time of the capacitor. Moreover, the core end will not be blocked during the impregnation, and the impregnation effect is good. After the impregnation, the residual liquid is directly filtered out in the impregnation box, and after the impregnation, it is directly grabbed and entered into the next process. It is impossible to vibrate and discharge the material again, saving the site and equipment space.
[0017] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all changes made according to the shape and principle of the present invention should be included in the protection scope of the present invention.
