摘　　要：为了解决当前全自动引线键合机送丝系统中的传输阻力大等问题,根据引线键合工艺过程和系统的技术要求,设计了气动送丝机构,利用空吸原理作用,实现金丝的低阻传输。通过建立气动送丝组件内的气压模型,借助COMSOL Multiphysics多物理场仿真软件进行仿真,得到了气压与送丝组件结构之间的关系,进而得到较好的送丝组件结构,为今后研制更加快速稳定的引线键合设备提供了很好的理论依据。To solve the problems of large transmission resistance of wire feed system in automatic wire bonder, pneumatic wire feeding mechanism based on air suction theory was designed to reduce the resistance of wire transmission. The model of air pressure in the pneumatic wire feeder was established, and the relationship between the pressure and the structure of the wire feeder was obtained with the help of COMSOL Multiphysics soft-ware simulation, thus, a better wire feeding component structure was obtained. It provides a good theoretical basis for the development of more rapid and stable wire bonding equipment.
