针对复合材料丝束手工搭接低效率及不稳定性的问题,在现有铺丝机基础上,研制了一套复合材料丝来自动搭接机构;在原有控制系统上增加独立模块,采用可编程控制器(Programmable logic controller,PLC)结合触摸屏的控制方式,实现各功能单元的逻辑运动及实时状态监控显示,并可对工艺参数进行设定.通过与原铺丝系统的联合调试,验证了丝束搭接系统的可行性和可靠性:丝束搭接区域能满足自动铺丝要求,大大缩短搭按时间,提高铺丝效率.%An auto-splicing apparatus of prepreg tow is designed to improve the efficiency and stability based on the fiber placement machine made before.The control system is built with the added independent modulus from the original one,and controlled with the help of programmable logic controller (PLC)and touch screen together.The logic movements of functional modulus,as well as the real-time displaying and the input of processing parameters,can be realized successfully.The validation of the feasibility and reliability of tow splicing system is completed by union debugging with the original system.It is concluded that the time of splicing is decreased significantly.Meanwhile,the quality of the splicing regions can meet the requirement of the fiber placement.
