Integrated cell laminating machine and cell laminating method

Abstract

The invention relates to the technical field of battery lamination, particularly to an integrated cell laminating machine and a cell laminating method. The integrated cell laminating machine comprises a laminating station, wherein the laminating station comprises a rotary plate, a rotary plate rotating apparatus arranged below the rotary plate for driving the rotary plate to rotate, and multiple laminating apparatuses uniformly arranged on the rotary plate for performing lamination; each laminating apparatus comprises a laminating rotary platform, a laminating power mechanism for driving the laminating rotary platform to swing in a vertical plane, and a first attraction mechanism and a second attraction mechanism which are symmetrically arranged on the two sides of the laminating rotary platform for attracting and driving a positive plate and a negative plate to swing in a vertical plane, and a diaphragm material-releasing mechanism mounted above the laminating rotary platform for supplying diaphragms, wherein each laminating power mechanism is positioned at the bottom of the corresponding laminating rotary platform; and the swinging track of the laminating rotary platform is externally tangent with the swinging track of the corresponding first attraction mechanism and second attraction mechanism. The integrated cell laminating machine has high laminating efficiency, high laminating precision and good laminating quality.

Description

technical field [0001] The invention relates to the technical field of battery stacking, in particular to an integrated battery stacking machine and a battery stacking method. 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] The cells of lithium-ion batteries are generally stacked, that is, they are stacked by positive plates, separators, and negative plates. Transfer the positive electrode and negative electrode from t...

Problems solved by technology

[0004] But this stacking method, on the one hand, in the stacking process, the diaphragm needs to move to the negative plate on the other side after the positive plate is stacked once, and the reciprocating distance of the diaphragm is long. Lamination, resulting in low work efficiency; second aspect, poor alignment of positive and negative electrodes during lamination, resulting in low lamination accuracy and poor lamination quality
