Abstract“全印制电子技术”是指采用快速、高效和灵活的数字喷墨打印技术(Digital Printing Inkjet Technology)在基板上形成导电线路和图形,或者形成整个印制电路板的一种工艺方法,也称为“可印制电子技术”或者简称为“印制电子”。现代全印制电子设备以纳米颗粒导电材料、高分子半导体材料、石墨烯/碳纳米管等作为喷印材料,在指定的基材上打印非硅电子器件、电子电路、纳米器件,因此对喷印设备控制系统性能,比如稳定性、实时性和精确性等提出更高的要求。此外为了适应各种新型电子材料的物理特性和流体力学特性(如表面张力、微滴粘稠度、固化温度、射流速度等),要求喷印控制系统具有更高的精度和更宽的调节范围。针对上述问题,本文设计了一种面向高速喷印制造工艺的控制系统。本文首先针对国内外有关全印制电子技术和高速喷印设备的研究现状进行了综述,重点分析了国内外通用喷印设备的工作原理、各个模块的作用,以及在电子制造行业当中应用,在此基础上展开如下工作:深入剖析了高速喷印设备工作原理与控制过程,围绕上位机数据处理与控制系统、喷印设备主控系统和喷印设备喷头控制系统三部分展开研究。设计并开发了高速喷印设备主控系统中用于传送打印数据和命令的USB通信、用于存储打印数据的SDRAM存储、支撑硬件电路工作的电源等软硬件子系统。结合控制对象Konica KM1024KM喷头的工作原理和控制时序要求,提出了喷头控制部分的硬件板卡与软件系统设计方案,开发了喷头正常工作所需要的电压控制电路、温度控制电路和波形控制电路的硬件电路与软件控制程序。最后,结合上位机数据处理与控制系统的功能结构、工作原理,重点从喷头测试与校正、图形数据处理和喷头电压与温度控制三个方面,设计并开发了相应的软件系统。在以上的工作基础之上,通过大量的喷印实验,实验结果表明该控制系统达到了较好的喷印效果,为高速喷印设备的开发提供了一个很好的解决方案。; “Fully printed electronic technology "defines that forming a conductive line and graphics at the substrate or the entire printed circuit board by adopting a fast, efficient and flexible digital inkjet printing technology, also known as” printed electronics technology "or" printed electronics ". When modern printed electronics devices print non-silicon electronic devices, electronic circuits and nano-devices using nanoparticle conductive material, polymer semiconductor material and graphene/carbon nanotube new electronic materials, they require the printing machine control system with higher stability, real-time and accuracy. Furthermore, in order to adapt to the physical characteristics of all kinds new electronic materials and Hydrodynamics (such as surface tension, viscosity droplets, curing temperature, jet velocity, etc.), it requires that the printing control circuit provides higher accuracy and wider regulation range. In response to these problems, this paper designes a control system for high-speed printing and manufacturing process. Firstly, this paper discusses the research status of printed electronics technology and high-speed jet printing equipments at home and aboard, which focuses on the working principle of common jet printing machine and the function of each module. In addition, narrates the specific applications of high-speed jet printing in the PCB manufacturing industry, based on the above analysis, the work is as follows. Analysis of the working principle and control process of high-speed jet printing machine and doing research on PC date processing and control system, master control system of spray printing machine and Spray printing machine nozzle control system. Design and development the hardware and software subsystems, mainly including USB communication that is used to transfer print data and command in high-speed jet printing equipment control system, SDRAM memory fault system used to save the printing dates and power supply system supporting hardware circuit to work. Combing the working principle and control timing requirements of the control object ( Konica KM1024KM nozzle ) ,this paper proposes the hardware board and software system design scheme of nozzle control and develops hardware circuit and software control programs including voltage control circuit ,temperature control circuit and waveform control circuit ,which can guarantee the nozzle normal operation. Finally , this paper introduces function structure and working principle of the PC image processing and control system, at the same time, design and development the corresponding software system from nozzle testing and calibration, image file and parse , voltage and temperature control of nozzle. Through a lot of spary experiments, proving that the control system achieved a good jet printing efferct, thence, it provides a good solution for the development of high-speed jet printing equipment.
