摘要：

Aiming at the phenomenon that high-viscosity multi-component adhesives are difficult to control due to viscosity changes, a mechanism using piston to dispense is designed. By analyzing the flow properties of multi-component adhesives, a consistency coefficient related to the mixing time of each component of the glue is introduced to the shear stress of the colloidal by its physical meaning, so the viscosity changes could be characterized during the dispensing process. The model of the dispensing system was established by the viscous fluid mechanics and the estimation function of the flow rate out of needle was given. According to the experimental verification of the specific adhesive, the dispensing system designed in this paper can directly control the amount of dispensing by adjusting the motor pulse frequency and the dispensing time. In the case, the simulation results are basically consistent with the experimental results, and the flow error can be kept within 10(-9)m(3)/s to realize the quantitative dispensing of the high-viscosity multi-component adhesive.
