摘要/Abstract

摘要： 针对当前纤维缠绕设备辅助系统自动化程度较低的问题,设计了一种机器人纤维自动挂切纱机构,并重点对关键挑切模块的断纱效果进行了实验研究。选用工业领域广泛使用的玻璃纤维和环氧树脂作为本次研究的材料,分别在干纱和浸胶两种状态下,研究了纤维根数、刀片距离及施加张力对纤维切断瞬间机器人末端轴旋转角度的影响;同时,对比分析了丝束断口形貌以评估切断效果。实验结果表明:机器人末端轴旋转角度随纤维根数增加而增大,随刀片距离或张力的增大而减小;在较高张力条件下,浸胶处理对断纱效果无显著影响;相同实验条件下,处于浸胶状态的玻璃纤维丝束所需最小切断力更小,且其断口形貌更为理想。

Abstract: Aiming at the problem of low automation of the auxiliary system of fiber winding equipment, a robot automatic fiber hanging and cutting mechanism is designed, and the yarn breaking effect of key picking and cutting modules is emphasized and experimentally studied. Glass fiber and epoxy resin, which are widely used in the industrial field, are selected as the materials for this study. The influence of the number of fibers, the distance between the blades and the applied tension on the rotation angle of the robot end axis at the moment of fiber cutting is studied under both dry and impregnated states. At the same time, the morphology of the fiber bundle fracture is compared and analyzed to evaluate the cutting effect. The experimental results show that the rotation angle of the robot end axis increases with the increase of the number of fibers, and decreases with the increase of the distance between the blades or the applied tension. Under the condition of high tension, the impregnation treatment has no significant effect on the cutting effect. Under the same experimental conditions, the minimum cutting force required for the glass fiber bundle in the impregnated state is lower, and the morphology of the fracture is more uniform.
