Abstract

Micro droplet dispensing has great potential in biopharmaceuticals, drug screening, printed electronics and other fields. Its distribution speed, size, and direction is the main factor affecting the quality of the distribution, but it is too difficult to monitor these parameters above when the droplet distributes in high frequency. This paper presents a monitoring method based on imaging of stroboscopic and delay, this method adjusts the delay time between the control signal of nozzle and CCD and LED, to obtain images at different positions of cycle. Then LabVIEW applies the image processing algorithm to the image for online processing to achieve monitoring the parameters above of the droplet distribution online. This paper uses the monitoring system designed to measure the parameters above, and then explored the impact of the driving wave, air pressure, voltage needed for the droplet dispensing on distribution. Experiments found that the method using the monitoring system based on imaging of stroboscopic and delay achieve monitoring the motion parameters in droplet distribution online, and the system measures the volume error within 2%, the deflection direction within ñ2øunder steady distribution of droplet; At present the analysis processing speed of monitoring system is 20 frames per second, it will feedback the monitoring parameters in the fastest 0.05 second, and provides technical support for the realization of a closed-loop regulation of the droplet distribution
