Problems solved by technology

[0003] However, the preparation process of this kind of battery is complicated, requiring a lot of time and energy to perform the sequential stacking process, it is not easy to realize mechanized operation, and the production efficiency is low
In the actual production process, the efficiency of lamination is mostly about 1 second per piece, and the battery cell is composed of multiple positive and negative pole pieces stacked. The current "Z-shaped" lamination method can no longer effectively improve production efficiency.

Embodiment Construction

[0043] The present invention will be further described below in conjunction with accompanying drawing:

[0044] refer to Figure 1-Figure 3 A lithium battery lamination device shown includes: a frame 10 , a molding assembly 20 , a support assembly 30 and a lamination platform 40 .

[0045] In this implementation, three sets of supporting components 30 and two sets of forming components 20 are taken as examples for illustration, and the number of supporting components 30 and forming components 20 can be adjusted according to actual needs.

[0046] refer to Figure 4-Figure 6 As shown, the support assembly 30 is fixed on the lower part of the frame 10 . Any of the supporting assemblies includes two supporting rails 31, two supporting sliders 32 that are movably connected to the two supporting rails 31, and a first drive for driving the two supporting sliders 32 to move along the supporting rails. Component 33.

[0047]As a preferred implementation of this embodiment, the fir...

Abstract

The invention relates to a lithium battery laminating device and a laminating method. The device is composed of a machine frame, a plurality of supporting components arranged at the lower part of themachine frame, a plurality of molding components arranged at the upper part of the machine frame, and a laminating platform arranged between the supporting components and the molding components. The invention can realize the rapid folding of the diaphragm and the positive and negative electrode sheets, has the advantages of large efficiency promotion space, good compatibility with the battery cell, simple and reliable structure, etc., can effectively replace the complex operation procedures such as the sheet taking, positioning, diaphragm folding and the like under the traditional Z-shaped lamination mode, and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a stacking device and a stacking method for lithium batteries. Background technique [0002] The battery cell of a lithium-ion battery is composed of a positive pole piece, a diaphragm, and a negative pole piece. At present, lithium batteries mostly use laminated battery cells: the diaphragm is folded in a "Z shape", and then inserted into the positive and negative pole pieces respectively. [0003] However, the preparation process of this type of battery cell is complicated, requiring a lot of time and energy to perform the sequential stacking process, it is difficult to realize mechanized operation, and the production efficiency is low. In the actual production process, the efficiency of lamination is mostly about 1 second per piece, and the battery cell is composed of multiple positive and negative pole pieces stacked. The current "Z-shaped" lamination method can no ...
