Problems solved by technology

[0002] There are processing errors in the height, thickness and width directions of the battery. When the battery module is formed into a PET tape, the pole height difference of the pole surface, the length of the module and the flatness of the side of the module have a great influence on the welding quality of the Busbar and the assembly of the PACK. Direct impact, when the pole height difference of the pole surface is greater than 2mm, the busbar welding of the module will produce virtual welding; the length of the module and the flatness of the side of the module are not controlled, and the welding track will deviate during the welding of the module Busbar, and the welding will be serious The track deviates from the pole; the PACK cannot be positioned accurately during assembly

Embodiment Construction

[0031] Hereinafter, the technical solutions of the present invention will be described in detail through specific embodiments, and many specific details will be set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation disclosed below.

[0032] The battery module 5 is an assembly structure obtained by connecting a plurality of cells according to a set line. Therefore, when each cell in the battery module 5 is manually or mechanically loaded and assembled, the sides of the cells are often misaligned and the poles are not aligned. Therefore, it is necessary to reshape the assembly structure of the battery module 5 in order to improve...

Abstract

The invention discloses a battery module shaping device and method, comprising a rack, and the rack is provided with a loading mechanism for loading battery modules, an end face shaping mechanism for shaping the end face of the battery module, and an end face shaping mechanism for shaping the battery module. The side shaping mechanism for shaping the side of the module, the end face shaping mechanism and the side shaping mechanism are both slidably connected with the loading mechanism; the shaping device can realize the shaping of the end face, side surface and pole surface of the battery module, and effectively control the pole surface of the pole cylinder. Height difference, module length and module side flatness.

Description

technical field [0001] The invention relates to the technical field of battery preparation, in particular to a battery module shaping device and method. Background technique [0002] The battery has processing errors in the height, thickness and width directions. When the battery module is formed by PET tape, the height difference of the pole cylinder, the length of the module and the flatness of the side of the module have great influence on the welding quality of Busbar and PACK assembly. Direct impact, when the height difference between the poles on the pole surface is greater than 2mm, the busbar welding of the module will produce virtual welding; the length of the module and the flatness of the side of the module are not controlled, and the welding track is offset during the welding of the busbar of the module. Trajectory detached from pole; PACK cannot be positioned accurately when assembled. SUMMARY OF THE INVENTION [0003] Based on the technical problems existing...
