RESEARCH ON THE INFLUENCE FACTORS OF THE DROPLETS VOLUME OF JETTING DISPENSER
Journal Title: Topics in Intelligent Computing and Industry Design (ICID) - Year 2017, Vol 1, Issue 2
Abstract
The droplets volume is an important indicator to evaluate the quality of dispensing, and there are many factors that affect the volume of droplets, such as the liquid viscosity, the fluid cavity temperature, the driving voltage of piezoelectric stacks, the rising time, the supply pressure of liquid, etc. To figure out the relationship between the influence factors and the droplets volume, this paper screened three major factors, namely the fluid cavity temperature, the driving voltage of piezoelectric stacks and the supply pressure of liquid, to study. Firstly, the temperature control system of fluid cavity was established, and the finite element analysis of the temperature field was verified, which turned out that the fluid cavity temperature stayed stable at the set value in the system. Then, the dispensing platform was built. Finally, the results of the experiment were analyzed though the range analysis method, and the results showed that the droplets volume increased with the three factors, and the fluid cavity temperature had the greatest influence on the droplets volume.
