Description

Technical Field

[0001] The utility model relates to the technical field of capacitor impregnation, in particular to an impregnation device for a laminated polymer capacitor. Background Art

[0002] Multilayer conductive polymer aluminum capacitors are a new type of solid-state capacitor. Compared to traditional wound solid-state capacitors, they utilize a multilayer stacked structure, enabling them to provide higher capacitance within a smaller volume. Multilayer conductive polymer aluminum capacitors offer low equivalent series resistance (ESR), excellent frequency characteristics, superior ripple current capability, and outstanding high-temperature performance.

[0003] Impregnation is a crucial step in the manufacturing of laminated conductive polymer aluminum capacitors. Impregnation involves infiltrating a specific medium (such as an electrolyte or other chemical liquid) into the pores of the aluminum foil, thereby extracting the capacitance and imparting electrical properties to the foil. This process has a direct impact on the performance of the capacitor, particularly playing a key role in improving its reliability, stability, and ultimately electrical performance.

[0004] During the aluminum foil impregnation process, the gaps inside the capacitor are filled with a filler material, which helps to reduce the intrusion of air and moisture, thereby reducing the risk of corrosion and oxidation inside the capacitor. This protective measure can significantly improve the reliability of the capacitor and ensure its stable performance during long-term operation.

[0005] Chinese patent application No. 202410865738.8 discloses a method for preparing a multilayer capacitor based on an n-type conductive polymer. The method comprises the following steps: obtaining a capacitor monolithic chip with an oxide dielectric layer on its surface, cleaning and drying the surface of the monolithic chip, impregnating the surface with a surface modifier solution, and then drying to obtain a surface-modified monolithic capacitor; sequentially impregnating the surface-modified monolithic capacitor monolithic chip with a polymerization monomer solution and an oxidant solution, drying after each impregnation step, and repeating the process 6 to 10 times until an n-type conductive polymer film is formed; then impregnating the monolithic capacitor with the n-type conductive polymer film with an outer film solution and heating and drying to achieve complete growth of the n-type conductive polymer on the oxide film; and finally impregnating the monolithic capacitor with a conductive carbon paste and a silver paste, followed by stacking and extruding to obtain a multilayer capacitor. This method reduces the equivalent series resistance of the multilayer polymer capacitor and effectively improves its operational stability in high-temperature and high-humidity environments.

[0006] China's patent application number CN202211596068.1 discloses a method for preparing a polymer laminate solid-state capacitor, and the method steps are as follows: S1: cutting and punching aluminum foil; S2: welding the punched aluminum foil to the Bar strip; S3: chemical formation, impregnation and carbonization; S4: stacking the single capacitor chip after carbonization in S3 into multiple layers, connecting the cathode part with conductive silver glue, and curing. After curing, cut off the effective area part to obtain a layer group, and then stack several layer groups on the lead frame, enter the oven for curing, and after curing, stack several layer groups on the other side of the lead frame, enter the oven for curing again, and then use a welding jig for welding; S5: edge sealing, plastic sealing, aging and molding to obtain a polymer laminate solid-state capacitor.

[0007] Existing impregnation equipment often uses a decentralized layout. When impregnating multiple solutions, a combination of impregnation machines, dryers, and cleaning machines for different solutions is required. This requires frequent equipment changes during impregnation operations, making operations cumbersome and inflexible, reducing the efficiency of the impregnation process. Furthermore, existing impregnation machines are limited to impregnation and lack intelligence, making them incapable of meeting the current high performance standards for capacitors. Therefore, the present invention discloses an impregnation device for laminated polymer capacitors to address these issues. Utility Model Content
