Description

Technical Field

[0001] The utility model belongs to the technical field of solid capacitor core packages, and in particular relates to a solid capacitor core package immersion device. Background Art

[0002] One of the steps in the processing of solid capacitor core packages is the vacuum impregnation process. After vacuum impregnation, the capacitor core package is taken out of the impregnation box through a fixed plane lifting mechanism. When the fixed plane lifting mechanism drives the capacitor core package to rise, the bottom of the core package is parallel to the electrolyte surface, resulting in a large contact area. The large contact area between the capacitor core package and the electrolyte causes the electrolyte to be adsorbed to the bottom of the core package due to excessive surface tension, resulting in waste of electrolyte and wet paper.

[0003] To this end, a solid-state capacitor core package impregnation device with announcement number "CN217768138U" is disclosed, including a vacuum box and a controller, the controller is installed on the side wall of the vacuum box, a vacuum assembly is movably connected to the top of the vacuum box, a groove is provided on the top of the vacuum box, and an installation groove is provided under the groove of the vacuum box, an impregnation box is installed on the top of the installation groove, and the installation groove is provided with a tilting pushing assembly, the front end of the tilting pushing assembly is higher than the rear end of the tilting pushing assembly, a capacitor core package carrier is inserted in the groove, and after impregnation, the tilting pushing assembly pushes the capacitor core package carrier to move upward, so that the capacitor core package carrier moves upward tiltedly; through the above method, the contact area between the bottom of the capacitor core package that moves upward tiltedly and the electrolyte is separated is reduced, the amount of electrolyte adsorption is reduced, and the electrolyte waste is reduced by about 20% to 35%. After the electrolyte is reduced, the use of wet paper can also be reduced.

[0004] However, for the above-mentioned solid-state capacitor core package impregnation device, although the capacitor core package is moved into the impregnation box and the electrolyte in the impregnation box performs vacuum impregnation on the capacitor core package, there are still the following obvious defects during use: when the capacitor core package enters the impregnation box for vacuum impregnation, due to the welding process on the capacitor core package carrier, some particulate impurities and dust will be attached to the surface of the capacitor core package, which will be left in the electrolyte during the impregnation, so that the electrolyte will be more turbid under long-term use, affecting the quality of the capacitor core package impregnation.
