基于专利信息的热复合堆叠设备专利技术分析研究OA

This study primarily analyzes the patent layout of thermal composite stacking technology,explores technological de-velopment trends and the competitive landscape,and provides references for enterprises in technological R&D,patent avoidance,and market competition strategies.During the analysis,patent data of enterprises such as CATL and GEESUN were retrieved through keyword combinations and IPC classification numbers.After merging patent families and denoising,quantitative and quali-tative analyses were conducted.The results show that related patents have entered a rapid growth period since 2022,with global layout concentrated in China,Europe,the United States,and WIPO.Technically,the focus lies in improving unwinding/cutting mechanisms and thermal composite rollers,emphasizing the enhancement of production yield and efficiency.However,patents re-lated to equipment safety and automatic adjustment are relatively scarce.It is found that leading enterprises dominate the patent landscape,and innovation spaces may exist in fields such as thermal composite pretreatment and automatic control.Enterprises can consider adopting avoidance designs for the core patented technologies of leading enterprises,while prioritizing breakthroughs in multi-station collaboration,safety design,and other directions to adapt to the technical upgrading needs of large-capacity battery cells.
