Abstract
The invention discloses a method for manufacturing a solid aluminum electrolytic capacitor. The manufacturing method comprises cutting, pinning and rolling, forming, impregnating, polymerizing, and assembling and sealing, and an aging test and a packaging process. The solid capacitor is directly placed in a sealed vacuum storage device after being polymerized, to store a to-be-assembled seal, vacuum degree of the sealed vacuum storage device is -50 to -99Kpa, relative humidity is <= 35%RH, and time from taking the capacitor out of the sealed vacuum storage device to enter the assembly sealingprocess is <=60s, and vacuum storage time is <=48h. The manufacturing method adopts a vacuum sealing box instead of a high-temperature constant temperature moisture-proof drying oven, and realizes workpiece moisture-proof storage after high-temperature polymerization of the capacitor and before assembly sealing. Compared with constant temperature storage of a drying oven in an existing method, power consumption is lower, power consumption per day is reduced to 4 DEG from original 108 DEG and is reduced by 96.30%, so energy saving effect is remarkable and production cost can be significantly reduced.
Description
technical field [0001] The present invention relates to the technical field of manufacturing solid capacitors, and more particularly, to a method for manufacturing solid aluminum electrolytic capacitors. Background technique [0002] At present, the production process of solid capacitors is roughly: cutting—nailing—formation—impregnation—polymerization—assembly sealing—aging test—packaging. Yes: Store in an oven at a constant temperature of 85-105°C to prevent moisture and dehumidify. Use a large dehumidifier to control the relative humidity outside the box to 35% RH or even below 30% RH. This method consumes a lot of electricity during the production process. The cost is high, and the total production cost increases accordingly. [0003] Therefore, providing a solid capacitor production method with low energy consumption and stable product quality is of great significance for energy saving and emission reduction in the production of solid capacitors.
