Equipment for stacking battery cells into shell

Abstract

Battery cell stacking and shell entering equipment comprises a positioning workbench, a battery cell transferring and clamping mechanism and a battery cell shell entering driving mechanism, the battery cell transferring and clamping mechanism is matched with the positioning workbench so as to transfer battery cells on the positioning workbench, and the battery cell shell entering driving mechanism is connected with the battery cell transferring and clamping mechanism so as to drive the battery cells to enter the shell. The battery cell transferring and clamping mechanism is driven to install the battery cell into the battery cell shell, battery cell stacking and fixing and battery shell fixing are achieved through the positioning workbench, then the battery cell is installed into the battery shell from the positioning workbench through the battery cell transferring and clamping mechanism and the battery cell shell entering driving mechanism, and battery cell stacking and shell entering are completed in a one-stop mode. And the accurately controlled battery cell stacking extrusion force and the overall length state of the battery cell in the battery cell stacking process are kept until the battery cell enters the shell, so that the effective transmission of the process and the stability of the battery cell entering the shell are ensured.

Description

technical field [0001] The invention belongs to the field of assembly of power battery modules, and in particular relates to a device for stacking battery cells into a shell. Background technique [0002] With the development of society, batteries play an increasingly important role in production and life. In the process of battery production, it is often necessary to assemble batteries and battery casings. The current stacking technology solution is to combine insulating sheets, Cells, buffer foam, cells, etc. are stacked one by one. During the process, parameters such as cell stacking pressure and displacement can be precisely controlled. The tooling needs to be changed and handed over, which destroys the state of the cells when they are stacked in groups, resulting in the inability to effectively transmit the pressure and displacement process parameters guaranteed during stacking, and the key process data is missing, making it difficult to ensure the accuracy of the cells...

Problems solved by technology

[0003] In view of the above deficiencies, the technical problem to be solved by the present invention is to provide a battery cell stacking and shelling device, which solves the problem that the battery cells need to be transferred twice after the stacking is completed, resulting in the overall extrusion force and length state of the battery cells being in the shell. control problem
