Cylindrical lithium battery full-tab flattening machine

Abstract

The invention discloses a cylindrical lithium battery full-tab flattening machine which comprises a rack, a main shaft and the like, and further comprises a battery turntable, a flattening turntable,a pushing assembly, and a plurality of battery clamping stations and flattening assemblies which are circumferentially and uniformly distributed, have the same number and are in one-to-one correspondence. During working, the main shaft drives the battery turntable and the flattening turntable to rotate synchronously, each flattening assembly rotates and revolves around the main shaft, and when thelithium batteries enter a battery clamping station and are driven by the battery turntable to rotate continuously, the flattening assemblies in one-to-one correspondence move to be attached to the end parts of the lithium batteries, rotate to knead all tabs and then move to be separated from the end parts of the lithium batteries; and at the moment, the lithium battery with the flattened full tabs continues to rotate along with the battery turntable until the lithium battery is driven to be separated from the battery clamping station. In the manufacturing process, since the flattening actionof the full tab at the end part of the lithium battery is continuously and automatically finished, the production efficiency is higher, the manufacturing process is simpler and more labor-saving, andthe requirement of an automatic assembly line for producing the lithium battery is better met.

Description

technical field [0001] The invention relates to a flattening machine for automatically flattening all tabs at the end of a lithium battery, that is, a flattening machine for all tabs of a cylindrical lithium battery. Background technique [0002] With the improvement of the performance requirements for the safe use of lithium batteries, the manufacturing method and manufacturing process of lithium batteries have also been changed accordingly. The lithium battery manufactured by using the full tab manufacturing method can better reduce the loss of lithium battery due to excessive current concentration. Safety risks such as spontaneous combustion or explosion. However, the full tabs protruding from the end of the lithium battery are all manually rotated and flattened. Even if there are production machines that can be used for flattening the full tabs, most of them use intermittent, single-station semi-automatic manufacturing methods. The manufacturing method is not only cumbe...

Problems solved by technology

However, the full tabs protruding from the end of the lithium battery are all manually rotated and flattened. Even if there are production machines that can be used for flattening the full tabs, most of them use intermittent, single-station semi-automatic manufacturing methods. The manufacturing method is not only troublesome and laborious, but also extremely low in production efficiency, which has become increasingly difficult to meet the needs of automated assembly line production of lithium batteries
