Automatic pre-pressing mechanism applicable to multi-specification capacitor cover plates

Abstract

The invention discloses an automatic pre-pressing mechanism applicable to multi-specification capacitor cover plates. The automatic pre-pressing mechanism comprises a bottom plate, a protective cover, a linear lifting assembly, a pre-pressing air cylinder assembly, a connecting shaft, a locking screw and a pre-pressing die, wherein the bottom plate is used for fixing and mounting the linear lifting assembly; the protective cover is used for performing sealing and dust preventing on the linear lifting assembly; the linear lifting assembly is fixedly mounted on the bottom plate, and used for controlling up and down movement of the pre-pressing air cylinder assembly and the pre-pressing die; the pre-pressing air cylinder assembly is used for controlling the pre-pressing die to automatically pre-press multi-specification cover plates; one end of the connecting shaft is connected with a piston rod of a pre-pressing air cylinder while the other end is connected with the pre-pressing die; the locking screw is used for tightly locking the pre-pressing die on the connecting shaft; and the pre-pressing die comprises a pre-pressing shaft and a pre-pressing main body. The automatic pre-pressing mechanism is simple in structure, convenient to use, high in cover plate pre-pressing stability and capable of realizing automatic pre-pressing on the cover plates of different specifications.

Description

technical field [0001] The invention relates to the field of automatic preloading, in particular to an automatic preloading mechanism adaptable to multi-standard capacitor cover plates. Background technique [0002] The manufacturing process of aluminum electrolytic capacitors mainly includes nailing and winding of electrode foil and electrolytic paper, electrolyte impregnation, pin puncture, cover plate riveting, aluminum shell glue filling, core packing into shell, cover plate preloading, high temperature aging, Aluminum shell sealing and other processes. In recent years, the performance of my country's self-developed aluminum electrolytic capacitor production equipment has been continuously improved, and the production efficiency has been greatly improved. However, there are still problems such as low processing accuracy, poor reliability, easy wear and tear of equipment, and high worker intensity. [0003] After completing the process of puncturing the pins of the cap...

AI Technical Summary

Problems solved by technology

At present, domestic manufacturers of aluminum electrolytic capacitors mainly use manual or semi-automatic methods in the pre-pressing process of capacitor covers. Affected by human factors, the pre-pressing quality of cover plates is unstable and the production efficiency is low; at the same time, different specifications Capacitors (including the cover plate) have different heights, and the height of the cover plate preloading mechanism needs to be manually adjusted, which is laborious and has a low degree of automation
