摘　　要：目的设计一种基于PLC控制的血型卡自动灌液系统,并应用于实际生产中,解决灌液后液内有小气泡、药液挂壁等问题。方法机械结构应用CAD制图软件进行绘制,然后按照图纸进行机加工。系统采用台达DVP 48EH PLC控制气缸与步进电机带动定位锥固定板和灌液针管固定板运动,实现定位锥对血型卡的精准定位和对灌液针管在血型卡内下降行程的精确控制,同时结合XMP6000微量泵将定量药液注入到血型卡内。结果实际生产过程中,灌液后液内有小气泡、药液挂壁现象得到了大大改善。结论该系统在运行过程中,达到了工艺要求,且操作便捷,可靠稳定安全,自动化程度高,适用于中小型企业的生产。The work aims to design an automatic filling system based on PLC control for blood type card and apply it to the practical production, so as to solve the phenomenon of generation of air bubbles and wall-hanging liquid after filling. The mechanical structure should be drawn with CAD drawing software and then machined as per the drawing. The system adopted Delta DVP 48 EH PLC to control cylinder and stepping motor to drive the fixed plates of locating cone and needle tubing for filling, so as to achieve the precise positioning of the blood type card by locating cone and the accurate control of descending stroke of needle tubing for filling in blood type card. Meanwhile, the quantitative liquid was injected into the blood type card combined with XMP6000 micro-pump. In the actual production, the phenomenon of generation of air bubbles and wall-hanging liquid after filling was greatly improved. The system has reached the technological requirements in the process of operation, and it is easy to operate, stable, reliable, safe and of high automation, which is applicable to the production for small-/medium-sized enterprises.
