Automatic shell closing device for lithium-manganese button cell

Abstract

The invention discloses an automatic shell closing device for a lithium-manganese button cell. The automatic shell closing device is characterized by comprising an upper supporting plate for shell closing, a lower supporting plate for shell closing, a shell closing cathode push-in unit, a shell closing cell discharge unit, a shell closing cell return unit, a shell closing anode push-in unit, a shell closing unit, a jacking unit for shell closing, a shell closing machine driving unit and the like, wherein the upper supporting plate for shell closing and the lower supporting plate for shell closing are fastened on a workbench for a shell closing procedure; the shell closing cathode push-in unit, the shell closing cell discharge unit and the shell closing cell return unit are fastened on the lower supporting plate; the shell closing anode push-in unit and the shell closing unit are fastened on the upper supporting plate; the jacking unit for shell closing and the shell closing machine driving unit are fastened on the workbench. According to the shell closing device disclosed by the invention, an anode shell and a cathode shell are placed in an integral die sleeve reforming block so as to be subjected to shell closing; through jacking the cathode shell into the reforming block and simultaneously pressing down the anode shell, the automatic shell closing of the anode shell and cathode shell of the lithium-manganese button cell is realized in one reforming block. The automatic shell closing device can be used for not only greatly improving the production efficiency and production speed of a product line, but also improving the product quality.

Description

technical field [0001] The invention relates to button battery manufacturing equipment technology, in particular to an automatic casing closing device for lithium manganese button batteries.

Problems solved by technology

However, in the existing shell closing device, the negative shell is positioned first, and then the positive shell is moved by pushing shovel or suction cup to buckle the positive shell onto the negative shell, and then close the shell. The whole process is carried out in space, so there is a problem , it cannot be guaranteed that the positive electrode casing is completely buckled on the negative electrode casing coaxially and concentrically, so that the failure rate of the equipment casing is high, the product rejection rate is high, the production efficiency is low, and resources are wasted
