Title:
NOVEL NON-NEWTONIAN FLUID MICRO-COATING SYSTEM AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/129100
Kind Code:
A1
Abstract:
A novel non-Newtonian fluid micro-coating system, comprising a non-Newtonian fluid material loading mechanism, a fluid modeling unit, and an intelligent feedback coating control unit. The non-Newtonian fluid material loading mechanism comprises a material storage pressure tank (101) provided with a pressure regulating valve and an ejector pin valve type nozzle (107) connected to a feeding pipeline (103); the pressure regulating valve controls air pressure of the material storage pressure tank (101); a fluid can be pressed into the feeding pipeline (103) and then ejected from the nozzle (107); the fluid modeling system is responsible for performing process analysis on non-linear characteristics of the non-Newtonian fluid and dynamically modeling a micro-coating process; the intelligent feedback coating control system comprises an upper computer (112), a signal input module (111), a controller (109), a controlled object module, a measurement unit, and an execution module, and is responsible for feedback control of the flow rate of the pipeline fluid on the basis of a non-Newtonian fluid model. The system solves the problem that existing micro-coating processes do not perform feedback control according to non-linear characteristics of fluids, and can be applied to various surface coating processes such as paint spraying and fluorescent powder glue coating.
