The continuous quantitative dispensing system gets the trajectory coordinates by CCD image recognition, then the dispensing head is automatically positioned by motion control platform. Pressure controller is selected to automatically control the pressure of compressed air in order to ensure gas pressure is steady. Peristaltic pump is used to guarantee the precision of the automatic program-controlled colloid transmitting. Colloid volume, dispensing head position and dispensing accuracy can be effectively guaranteed. The experimental results show that the whole system fully meets the double fluid dispensing design requirements, and program interface is friendly and easy to operate. It can apply for product promotion and widely application.
