Lamination material pressing method for solid electrolyte aluminum electrolytic capacitor

Abstract

The invention relates to a laminated material pressing method for a solid electrolyte aluminum electrolytic capacitor. The laminated material pressing method comprises a first tray, a second tray, a pressure block, a wireframe sheet, a conveying machine table, a manipulator and a sliding rail, a hollow strip-shaped groove is formed in the middle of the first tray; the first tray is tightly buckled and stacked above the second tray; the wire frame sheet is arranged in the strip-shaped groove in the first tray; the mechanical arm is composed of a clamping foot, a mechanical transmission part, a support and a sliding block, the foil lamination layers are placed on the wireframe piece, one end of each foil lamination layer is fixedly connected with the wireframe piece through cold welding, and the foil lamination layers are bonded and fixed through elargol. And the pressure block is placed on the first tray, and the pressure block extrudes, forms and solidifies the foil laminated layer. The pressure block is pressed on the foil lamination layer subjected to single-side cold welding and silver colloid smearing in the wire frame sheet through the mechanical arm, the foil lamination layer obtained after curing cannot be loosened after being placed for a long time, and the problem that in traditional foil lamination layer machining, the edge of the foil is warped, and consequently a product is poor is solved.

Description

technical field [0001] The invention belongs to the field of electrolytic aluminum electrolytic capacitor manufacturing equipment, in particular to a method for lamination and pressing of solid electrolyte aluminum electrolytic capacitors. Background technique [0002] With the trend of thinning and flattening electronic components, the appearance of capacitors will also change accordingly, from the traditional cylindrical shape to laminated capacitors, and this production process will gradually compress the foil stacking space. There is an urgent need to adopt new technology and new equipment for production. In the manufacturing process of multilayer capacitors, the foil laminated on the product wireframe is connected and solidified by silver glue and cold welding. Currently, there is no such thing on the lamination machine. A device that prevents the foils on the wire frame from lifting and loosening. Before curing, due to the long storage time, the foils connected and sta...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for lamination and pressing of solid electrolyte aluminum electrolytic capacitors. The pressure block is automatically pressed by a manipulator into the wire frame sheet for unilateral cold welding and foil lamination with silver glue applied. In addition, the cured foil laminate will not loosen after being placed for a long time, which solves the problem that the foil laminate will be pried apart during the production process of the foil laminate before high-temperature curing in the traditional process, resulting in a gap between the foil laminates. Warped edges, bulges or air bubbles, resulting in defective products, such as ESR increase and other problems
