摘要: 为解决软硬混编预制体成形过程中窄缝通道引纬环节手工操作导致的劳动强度大、成形效率低的问题,设计出一种基于连续碳纤维束S形引纬轨迹的自动化引纬系统。通过分析S形引纬轨迹的形成机理,建立了碳纤维束位置与各机构动作的协同关系,并据此设计了以递纬机构、电子引纬机构、已引纬纱控制机构为核心的系统架构。样机实验表明该系统能在窄缝通道中实现12.5纬/分钟的连续稳定引纬。

Abstract: To address the issues of high labor intensity and low forming efficiency caused by manual weft insertion in narrow channels during the forming processes of soft-hard blended preforms, an automated weft insertion system was developed based on an S-shaped trajectory of continuous carbon fiber tow. The formation mechanism of the S-shaped trajectory was analyzed to establish the synergistic relationship between carbon fiber bundle positioning and coordinated multi-mechanism motions. A system architecture was designed, with the weft delivery mechanisms, electronic weft insertion mechanisms and post-insertion control mechanisms as the core components. Prototype experiments demonstrate that the system achieves continuous and stable weft insertion in narrow channels at a rate of 12.5 picks per minute.

Key words: soft-hard blended preform, narrow-channel weft insertion, continuous carbon fiber tow, S-shaped trajectory, weft insertion system
