Precise Dispensing Quantity Gauging and System Design Using Mass Difference and Ultra-Infinitesimal Lead/Diameter Ratio of Screw Transmission

Based on redundant method, a precise dispensing quantity gauging system was put forward, with coalescence of the dispensing part mass difference or the average corresponding value of the masses of the part before and after the glue dispensing and the ultra-infinitesimal lead/diameter ratio screw transmission to control the variation of glue barrel volume precisely. A self-lubricating double guide rail design was developed to ensure dispensing quantity and control the glue drop strictly within(0.200±0.001)g. By using modular design, a high precision dispensing machine was realized with moderate flexibility. Through modular simulating prototype, the spatial structure and the reliability of dispensing machine were optimized. Experimental study shows that the proposed solution can guarantee real-time controlling the dispensing quantity precisely,which meets the requirements of the production rhythm.
