Abstract

The invention discloses a liquid flow control system for liquid crystal panel cleaning equipment, and relates to the technical field of liquid crystal panel manufacturing equipment control, and the liquid flow control system comprises the following steps: S1, determining a liquid flow control object and a cleaning working condition of the liquid crystal panel cleaning equipment; s2, constructing a corresponding liquid flow reference by using the cleaning working condition and the liquid flow control object; s3, performing liquid flow distribution and performing association construction by using the flow reference result; s4, performing operation constraint integration by using the liquid flow control state set; and S5, constructing system-level output of the liquid flow control system by using the controlled liquid flow state. According to the method, the liquid flow reference which can be directly implemented is set, so that clear and quotable flow reference results can be provided for each cleaning function unit under different cleaning working conditions, and a unified and reliable foundation is provided for liquid flow distribution and execution association construction.
