The pole piece loading device provided by the invention is simple in structure, high in efficiency, stable to operate and good in lamination effect.

Description

technical field [0001] The invention relates to the technical field of battery pole sheet processing equipment, in particular to a sheet loading device for a cell winding and stacking machine. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Because of the above-mentioned characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, notebook computers, video cameras, and digital cameras. [0003] In the manufacturing process of lithium batteries, a laminating machine is usually used to assemble the positive and negative electrodes and separators of lithium battery cells into ...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, the stacking table can only pick up one pole piece at a time between the positive and negative poles. The long loading time leads to slow lamination speed. The lamination speed is about 50p / m, and the work efficiency is low. Second, the whole machine The structure is complex, and the stacking table moves back and forth between the positive and negative electrodes and the operation is unstable, resulting in poor lamination effect
