Manufacturing method and manufacturing equipment of battery metal cover plate

Abstract

Embodiments of the present invention relate to a preparation method for a battery metal cover plate, and preparation equipment thereof. The battery metal cover plate is applicable for a sealing cover of a battery metal shell. The battery metal cover plate comprises a metal support connected through rivets, insulation glue and nickel plates. The preparation method for the battery metal cover plate comprises steps of metal support punching, insulating glue injecting, nickel plate punching, rivet installing, nickel plate blanking, rivet pressing and cover plate blanking. The steps of the nickel plate punching, the rivet installing, the nickel plate blanking, the rivet pressing and the cover plate blanking are performed in a set of composite progressive mold. The preparation equipment comprises a first punching machine provided with a support punching die, an injection molding machine provided with an injection mold, a second punching machine provided with the composite progressive mold, and a rivet transportation apparatus used through combination with the second punching machine. According to the embodiments of the present invention, the problems of low production efficiency and low product qualification rate of the metal cover plate are mainly solved, such that a purpose of great improvements of the production efficiency and the product qualification rate of the metal cover plate is achieved.

Description

technical field [0001] Embodiments of the present invention relate to a method for manufacturing a battery metal cover plate and manufacturing equipment thereof. Background technique [0002] The battery metal cover is used to cover the metal shell of the battery. As the battery shell, the metal shell is widely used in the battery packaging of mobile phones, computers, electrical appliances and other electronic communication products. The battery metal cover includes metal brackets, insulating glue, nickel sheet and the rivet that riveted the three together. The manufacturing method of the metal cover plate of the battery is generally as follows: first, stamping to form a metal bracket; In the rivet hole of the casing, the fifth is to manually set the nickel sheet on the rivet of the metal bracket, and finally press the rivet to rivet the three to form the metal cover plate of the battery. Since it is necessary to manually install each rivet and each piece of nickel on each...

AI Technical Summary

Problems solved by technology

Since it is necessary to manually install each rivet and each piece of nickel on each metal bracket, and then manually perform riveting, its production efficiency is low; and due to the large errors caused by human factors in the manual installation and riveting process, its The qualification rate of the product is also low
