摘要
为提高电流体喷印平台打印复杂图案的兼容性和效率，提出了一种以图像解析为基础，通过可编程多轴运动控制器（PMAC）调控工作电压、气压和运动参数的自动化按需喷印控制策略。设计了面向自动化电流体喷印平台的控制系统，实现了位图图像的自动化按需打印。该控制系统以PMAC数字运动控制卡为控制核心，以工控机为上位机，选择VC＋＋作为用户界面软件的开发环境。在验证喷印方法和控制系统的有效性之前，结合控制策略和控制时序图，进行了虚拟打印仿真。试验证明，所提出的自动化喷印方法及设计的控制系统能有效实现从位图输入到基底图案自动化打印成形，有效提高了电流体喷印平台的应用拓展性，为印刷电子、大规模传感器制备、生物医药领域的研究发展奠定了良好基础。
In order to improve the compatibility and efficiency of electrohydrodynamic jet printing platform for printing complex patterns,an automated ondemand jet printing control strategy is proposed based on image analysis and the programmable multiaxes controller（PMAC） to control the working voltage,barometric pressure and motion parameters. A control system is designed for the automatic electrohydrodynamic printing platform,to implement the bitmap image automated ondemand printing. In this system,the PMAC digital motion card is used as the control core,the industrial PC is used as the host computer,and VC＋＋ is selected as the user interface software development environment. Prior to verifying the effectiveness of the printing method and the control system,virtual simulation is carried out in combination with the control strategy and the control timing diagram. Experiments verify that the proposed automatic jet printing method and the designed control system can effectively realize the automatic printing from the bitmap input to the pattern on the substrate,which can effectively improve the applicable scalability of the electrohydrodynamic printing platform and establish good foundations for the research and development in printed electronics,largescale sensor fabrication and biomedicine fields.
