Automatic lamination production line of power lithium battery piece

Abstract

The invention discloses an automatic lamination production line of a power lithium battery piece, and belongs to battery piece manufacturing. The automatic lamination production line structurally comprises automatic membrane feeding devices, automatic pole piece feeding devices, a power transfer device, a membrane cutting-off device, a mylar unwinding device, a heat sealing machine, a mylar winding device and an automatic battery piece boxing device. The automatic membrane feeding devices, the power transfer device, the membrane cutting-off device and the mylar unwinding device are arranged on a membrane feeding support respectively, the three groups of automatic pole piece feeding devices comprise two groups of automatic negative pole piece feeding devices and one group of automatic positive pole piece feeding devices, and the two groups of automatic membrane feeding devices are arranged between the three groups of automatic pole piece feeding devices. The automatic lamination production line of the power lithium battery piece has the advantages of being capable of saving labor, lowering the labor density of workers, improving the production efficiency and saving materials, high in processing quality, stable 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.
