Non-contact ultrasonic nozzle cleaner with closed loop automatic clogging detection

Systems and methods of operating and cleaning a coating system are disclosed. A method of applying a material to a substrate includes dispensing the material onto the substrate using an applicator configured to receive the material therein and expel the material therefrom toward the substrate; measuring a parameter of the material dispensed via the applicator; determining whether the parameter is within a predetermined range; when the parameter is not within the predetermined range, stopping dispensing the material onto the substrate and cleaning the applicator such that the parameter is within the predetermined range; and after cleaning the applicator, resuming dispensing of the material. 公开了操作和清洁涂布系统的系统和方法。一种将材料施用到基底的方法包括：使用施用器将材料分配到基底上，该施用器被构造成在其中接收材料并将材料从其中朝向基底排出；测量经由施用器分配的材料的参数；确定参数是否在预定范围内；当参数不在预定范围内时，停止将材料分配到基底上并清洁施用器，使得参数在预定范围内；以及在清洁施用器之后，恢复分配材料。
