Abstract

A battery core flattening device, which includes a base, a bracket, a first driving device and a pressing plate, the base and the first driving device are fixed on the bracket at a certain interval, and the pressing plate is connected to the first driving device , and the pressure required for crushing the battery core is provided by the first driving device, the pressure plate is arranged opposite to the base, the battery core crushing device also includes a rotating table, a chute and a baffle, The rotary workbench is arranged on the base and opposite to the pressing plate, and the chute and the baffle are arranged above the base for leading in and out of the winding core. The battery rolling core flattening device of the present invention can effectively save the flattening time and improve the flattening efficiency by setting a rotating workbench; in addition, by setting the chute and the baffle to guide the winding core into and out of the rotating workbench, it further improves flattening efficiency.

Description

technical field [0001] The invention relates to the field of lithium ion battery manufacturing, in particular to a flattening device for a wound lithium ion battery core. Background technique [0002] Since the concept of "rocking chair battery" (RCB) was proposed in 1980, Japan's Sony Corporation and Sanyo Corporation began practical research on lithium-ion secondary batteries in 1985 and 1988, respectively. With outstanding features such as large specific energy, small self-discharge, wide application temperature range, stable working voltage, and long storage life, all countries in the world are paying attention to the application of lithium-ion secondary batteries in the field of communications, portable electronic products, electric vehicles, and aerospace. Applications have shown great interest and enthusiasm, and a lot of research and improvements have been made on manufacturing equipment for lithium-ion secondary batteries. [0003] At present, semi-automatic equipm...
