Description

TECHNICAL FIELD

[0001] The utility model belongs to capacitor production equipment technical field especially relates to a kind of feeding mechanism of capacitor impregnator. BACKGROUND

[0002] The production process of aluminum electrolytic capacitor involves multiple steps, mainly including foil cutting, pinning, winding, impregnation, shell sealing waist, sleeve, aging charging selection, finished product, lead forming and other key links. In the impregnation process of the capacitor, the core package is first placed in an array in the impregnation tray, then the impregnation tray is placed on the impregnation screen plate in the vacuum impregnator. The vacuum impregnator first performs vacuum adsorption to extract the air in the micropores of the core package, thereby removing the moisture and gas inside the core package. Then, the impregnation screen plate is lowered by the lifting mechanism, causing the capacitor core package in the impregnation tray to contact the impregnation liquid. The electrolyte is fully adsorbed onto the surface of the anode foil and cathode foil. Then, the impregnation screen plate is raised again by the lifting mechanism for drying treatment to absorb the excess electrolyte on the capacitor core package. The impregnation liquid fills the capillaries and gaps of the material and forms a smooth paint film on the surface. Then, the cover plate of the vacuum impregnator is opened, and the impregnation tray is removed from the impregnation screen plate and placed in a new impregnation tray for impregnation. This process is repeated sequentially.

[0003] The existing vacuum impregnator generally has a cover plate at the upper end. Each time the impregnation tray is placed or removed, the cover plate needs to be opened, and the impregnation tray is manually placed or removed. On the one hand, this results in high labor intensity and low efficiency of manual operation. On the other hand, the frequent opening and closing of the vacuum environment in the vacuum impregnator affects the process stability. Moreover, after each time the cover plate is opened, the vacuum inside the vacuum impregnator needs to be re-established, which reduces the impregnation efficiency of the capacitor.
