摘　　要：为了提高空间太阳电池的封装质量,对自动封装机器人的注射器涂胶过程进行了建模与分析.基于非牛顿流体理论,建立了盖片胶的圆管流动模型,并使用有限元软件Ad ina进行了数值计算.根据理论模型求解出了针头段的速度场,同时得到了模型的数值解,二者进行了对比验证.从而获得了圆管流动出口流量的精确解,用于下一过程———平面扩散中盖片胶初始形状的计算.涂胶过程中的参数,包括:盖片胶粘度、注射器入口压强、针头直径,影响着涂胶量,进而影响着最终的封装质量.The syringe-coating process of an automatic bonding robot is studied in order to improve the bonding quality of space solar cells. Based on non-Newtonian fluid theory, a mathematical model of pipe flow of the adhesive was founded, and the finite element program ‘Adina＇ was employed to calculate the flow field. The velocity field of the needle section was worked out according to the theoretical model. Meanwhile, the numerical solution of the model was also calculated, and compared with the theoretical solution. Thus an analytical solution of the outlet flow rate of the needle was obtained to calculate the initial state of the adhesive in next planar spreading process. Three parameters in coating process, including the adhesive＇ s viscosity, the syringe＇ s inlet pressure and the needle＇ s diameter, affect the coating volume flow and the final bonding quality.
