摘要

摘要: 根据测量常规锂电池极片辊压过程后的厚度发现，极片厚度往往并不均匀。通过建立辊压机主动滚的受力数学模型，得出极片厚度不均匀机理。为改善这种现象，提高锂电池质量，提出对传统辊压机的结构优化改进，即在压辊两端安装轴承座与两组施力不同的液压缸。对优化后的辊压机进行Solidworks建模并进行优化分析，得到使压辊弯曲应力最小时应对液压缸的施力。并通过二次开发软件建立辊压极片的设计平台，可极大提高获取机构优化后的辊压机相关工作参数的速度。实验结果表明，优化后的辊压机可使锂电池极片厚度更为均匀，锂电池生产自动化水平度大幅提高。

Abstract: After measuring the thickness for normal pole piece of lithium battery after the process of rolling, the author has discovered that the thickness of pole piece is not uniform. By setting up mechanical mathematic model for the initiative roller of roller press, the non-uniformity mechanism of pole piece thickness has been figured out. To correct this disadvantage and promote the quality of the lithium battery, the proposal to improve the structure of traditional roller press has beendesigned, where the bearing seats and two sets of hydraulic cylinders with different forces will be installed at both sides of roller. a model and analysis for the optimized roller press via computer software Solidworkshave studied, from which we can work out the force applied on the hydraulic cylinder to ensure the minimum bending stress of the roller. Then set up design platform for pole piece of roller based on computer programming languages software to increase the speed to obtain related working parameters for optimized roller press. The experiment results have shown that the optimized roller press can make the thickness of lithium battery pole piece more uniform and greatly improve the automation level for the production of lithium battery.
