LED照明具有高亮度、低能耗、体积小、环保等特点，因此被认为是未来替代传统照明方式的最佳光源。而对于高粘度、高频、微量、高一致性的LED荧光粉点胶，目前还存在无法出胶、点胶性能不稳定、胶滴一致性不好等问题。首先阐述了LED照明的应用特点以及当前照明封装产业的技术水平，随后结合将来主流的喷射式点胶技术，利用Flow-3D软件建立了LED喷射点胶过程的计算机仿真模型。随后得到了点胶过程中胶液在喷胶阀内的流动情况，在此基础上又探讨了各因素对胶液喷射的影响规律。其结果可以为后续的研究奠定基础，同时对具体的LED工业生产及封装装备制造也有一定的参考价值。%LED lighting has high brightness, low power consumption, small size, environmental protection and other features, so it is considered to be the best source of future lighting method. For high viscosity, high frequency, high consistency of the LED phosphor dispensing, there are still some problems.Such as can’t jet glue, glue performance is not stable, dots consistency is not good and so on.The paper first describes the characteristics of LED lighting and the lighting package industry technical level, and then combined with the future mainstream jet dispensing technology, establish a computer simulation model of the LED jet dispensing process by using Flow-3D software. Then obtain the flow situation of glue dispensing process in the spray valve, and on the basis of it, discuss the factors to the glue injection. The results can lay a foundation for related research, also has certain reference function to the concrete LED industrial production and packaging equipment manufacturing.
