Flexible production system for power battery pack

Abstract

The invention relates to a flexible production system for a power battery pack. The flexible production system comprises a feeding device, a comprehensive testing device, a turnover device, a gluing and stacking device and a robot assembly. The feeding device comprises a feeding assembly, and the feeding assembly is used for driving a battery cell to move in the height direction of the feeding assembly; and the comprehensive testing device comprises a rotating disc and testing equipment, and the testing equipment is arranged in the circumferential direction of the rotating disc. According to the flexible production system for the power battery pack, all the devices operate automatically, manual participation is reduced, and the working efficiency is greatly improved. Meanwhile, all the devices are connected in series through the robot assembly and are convenient to combine, any single device can be combined with other production lines for use; and for machining battery cells of different models and sizes, the single device can be independently added into other production lines, so that the compatibility of battery cell production is improved, the equipment purchasing cost is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic production and assembly of battery packs, in particular to a flexible production system for power battery packs. Background technique [0002] Power batteries generally refer to batteries that provide power for electric vehicles, electric trains, electric bicycles, and electric tools. Generally, multiple single cells can be combined in series and parallel to form the required voltage and capacity, which is the so-called power battery pack. The production process of the power battery pack mainly includes: cell testing and sorting, stacking of cells into groups, and series-parallel welding of cells. Batteries are generally divided into three types: hard (aluminum / steel) shell batteries, soft-packed batteries, and cylindrical batteries. Compared with the other two batteries, soft-packed batteries are lighter in weight, higher in specific energy, and more flexible in design. The main cell type in ...

AI Technical Summary

Problems solved by technology

The design of the soft-pack battery is flexible, so it also leads to a variety of shapes and specifications, and the production process often needs to be "changed"

[0003] The current common power battery pack production lines mainly include manual production lines and automatic production lines. The disadvantages of manual production lines are poor quality control capabilities, heavy equipment management workload, and large personnel turnover.

Each process of the fully automated production line is closely related. When a certain process is suspended, it will affect the entire production line. In severe cases, the production line will be shut down.

The compatibility of traditional fully automatic production lines is poor, and often a production line can only be compatible with one type of product. For different types of products, multiple production lines are required, and the cost is high
