A kind of automatic shaping tooling and shaping method of lithium-ion battery module

Abstract

The invention relates to an automatic shaping tool for a lithium ion battery module. The automatic shaping tool comprises a base, a bottom plate, a supporting plate, a PLC, two shaping tightening assemblies, and a transmission regulating assembly, wherein the bottom plate is arranged on the base, and moves left and right along the base; the supporting plate is fixedly arranged on the bottom plate for placing the lithium ion battery module; the PLC is arranged below the base; the two shaping tightening assemblies are separately arranged at the two ends of the bottom plate, are not connected with the supporting plate, are controlled by the PLC to separately move left and right along the bottom plate for clamping or loosening the lithium ion battery module arranged on the supporting plate, so that shaping tightening is realized; and the transmission regulating assembly is arranged below the base, is connected with the bottom plate, is controlled by the PLC to drive the bottom plate to move left and right along the base for moving and regulating the shaped tightened lithium ion battery module to a proper welding position. The automatic shaping tool realizes automatic shaping of the lithium ion battery module, reaches the standard dimension of the module, effectively improves assembly efficiency to adapt to large-scale production, reduce a rework rate of the lithium ion battery module, improves product quality and optimizes process flow.

Description

technical field [0001] The invention relates to an automatic shaping tool and a shaping method for a lithium-ion battery module, in particular to an automatic shaping tool and a shaping method for a vehicle-powered lithium-ion battery module. Background technique [0002] In the prior art, the on-vehicle battery system is composed of multiple sets of high-energy lithium-ion battery modules, and the lithium-ion battery module is composed of multiple high-energy lithium-ion single cells. In the initial stage of mass production of lithium-ion battery modules, most production and assembly lines with a relatively low degree of automation use manual pulling of modules to tighten tooling to realize the assembly of lithium-ion battery modules. [0003] Due to the different lengths of lithium-ion battery modules, standard stoppers need to be added for alignment during the assembly process, so the module tightening tooling will be damaged if the standard stoppers are not used properly...

Problems solved by technology

[0003] Due to the different lengths of lithium-ion battery modules, standard stoppers need to be added for alignment during the assembly process, so the module tightening tooling will be damaged if the standard stoppers are used improperly

However, after one side of the lithium-ion battery module is welded, the standard stopper needs to be removed and the other end replaced, which is extremely inconvenient to operate and affects production efficiency. In addition, the size must be measured with a tape measure, and the size deviation is large. Neither the quality nor the quality of the products can meet the ideal requirements.
