Integrated multi-station plate and automatic guide pin clamping device for assembling aluminum electrolytic capacitors

Abstract

The invention discloses an integrated multi-station plate and automatic guide pin clamping device for assembling aluminum electrolytic capacitors. According to the invention, multiple groups of guidepin clamping manipulators are arranged at equal intervals in the circumferential direction at the bottom of an integrated multi-station plate, the clamping end of each guide pin clamping manipulator is located at the edge of the multi-station plate, a rubber cover is arranged below the integrated multi-station plate and located at a position perpendicular to the clamping end, and a core cladding guide pin of the small aluminum electrolytic capacitor passes through the rubber cover and then clamped and fixed by the clamping end. The device disclosed by the invention enables the multi-station plate to be molded at one time by using an integrated multi-station technology, is convenient to assembly and easy to be in place accurately, and improves the working efficiency; and the automatic accurate positioning guide pin clamping device at the bottom of the multi-station plate enables a core cladding to move stably in the assembling process, thereby greatly reducing the possibility of damaging a riveting part between an aluminum foil and a guide pin of the core cladding.

Description

Problems solved by technology

[0003] At present, one of the more widely used is the traditional core package assembly machine, which is mainly used for small electronic products, such as the assembly of lead products, patch products and solid-state products, the structure of small aluminum electrolytic capacitors like figure 1 As shown, there is a core package at the end of the guide pin. During assembly and positioning, due to the unreasonable structure of the multi-station disc in the traditional core package assembly machine, when the core package guide pin is inserted into the hole of the rubber cover, the core package B part The interference fit force generated by the outer diameter and the hole diameter of the rubber cover will cause the riveting joint between the A side of the guide pin and the aluminum foil in the core package to be damaged in varying degrees such as displacement, deformation, and damage.

At the same time, since only the guide pin of the core package is inserted into the rubber cover hole device on the multi-station disk, there is a large gap between the diameter of the guide pin and the aperture of the rubber cover hole, resulting in the difference between the coaxiality of the core package and the aperture of the rubber cover. The mutual shape dispersion is large, the verticality of the core package is poor, the movement is unstable during assembly and assembly, and some may shake. Damage, according to statistics, the damage rate can reach 5%~8% in severe cases

[0004] The above situations will eventually lead to poor electrical performance of the product

Especially for solid-state products, the leakage current of the product is too large or even exceeds the standard. This kind of damage is difficult to repair by subsequent aging treatment, which seriously affects the pass rate of the product.

[0005] It can be seen that the traditional core pack assembly machine can no longer meet the accuracy requirements of the current process technology due to the large defects in the assembly structure technology
