An automatic lamination production line for power lithium battery cells

Abstract

The invention discloses an automatic stacking production line for battery slices of power lithium batteries, which belongs to the manufacture of battery slices. Unwinding device, heat sealing machine, wheat wax sheet rewinding device and automatic battery sheet boxing device, the automatic diaphragm feeding device, power transmission device, diaphragm cutting device and wheat wax sheet unwinding device are respectively arranged on the diaphragm feeding On the bracket, the described pole sheet automatic feeding device includes three groups, which are respectively two groups of negative electrode sheet automatic feeding devices and a group of positive electrode sheet automatic feeding devices, and the described diaphragm automatic feeding device includes two groups, the The two sets of diaphragm automatic feeding devices are respectively arranged between the three sets of pole piece automatic feeding devices. The invention has the characteristics of saving labor, reducing labor density of workers, improving production efficiency, saving materials, high and stable processing quality, and the like.

Description

technical field [0001] The invention relates to the manufacture of battery slices, in particular to an automatic lamination production line for battery slices of power lithium batteries. Background technique [0002] The existing lamination processing in the power lithium battery cell industry is generally done manually or manually with a stand-alone device to complete the stacking of the pole piece and the cut diaphragm in the tooling mold, and then wrap the cut wheat wax sheet through the heat sealing machine, and finally Place the cells manually into the collection box. In the process of stacking power lithium battery cells, the turnover period of materials is long, there are many turnover devices, the utilization rate of diaphragm, wheat wax and other materials is low, and the waste is large; manual operation is cumbersome, production efficiency is low, and labor costs are high; in addition , Human factors have a high risk of impact on product quality.
