摘　　要：为满足非连续柔性基材输送系统特殊的工况需求,分析了卷绕系统中多种因素对基材中张力稳定的影响,提出了一种张力控制方法.该方案采用了一款8轴运动控制板卡,同时完成对张力控制、进给控制和卷绕控制的统一协调,并利用对料轴的卷绕进给位置指令迭代计算的方法,限制了非连续进给中的张力波动幅值.通过实验平台采集的张力数据分析结果表明:所提出的基于可编程多轴控制器(PMAC)多通道控制功能的张力控制方法实现了非连续基材输送系统中的张力稳定控制的目标,可满足部分柔性电子封装生产线的需求.实验分析还显示,在非连续卷绕进给工况中生产效率与张力波动幅值需求之间存在一定程度的矛盾,需要综合考虑.After the uncertain factors for tension stability were analyzed,a tension control method was proposed to fulfill special requirements in discontinuous winding processes. One eight-axis motion control card was used to control the tension,feeding,and winding,synchronously. An iterative method for calculating feeding position of the winding axes was investigated to restrict the tension vibration amplitude. The tension data gathered from the testing platform show that this tension control strategy,based on programmable multiple axis controller （PMAC）,is effectual for discontinuous winding systems and satisfies the needs of some flexible electronics product lines. The test curves also indicate that the requirements for tension vibration amplitude are in some contradiction with great productive efficiency and speed,and a tradeoff has to be made between them in different discontinuous winding jobsites.
