  • Patent number: 10376906
    Abstract: A gas and liquid knife and a control method thereof are provided. The gas and liquid knife includes a chamber and a knife head. An ejection opening is provided at the knife head The knife head has a first knife lip and a second knife lip. The ejection opening is defined between a first inner wall of the first knife lip and a second inner wall of the second knife lip. The chamber is defined between the first wall plate and the second wall plate slidably connected with each other. The first knife lip connects to the first wall plate. The second knife lip connects to the second wall plate. The first knife lip and second knife lip moves relatively as the first wall plate and the second wall plate slides relatively, such that a minimum distance between the first inner wall and the second inner wall could be changed.

  • Patent number: 10183315
    Abstract: A substrate cleaning device includes: a housing having a cleaning chamber therein; a plurality of spray pipelines pivotally mounted at the housing and distributed side by side along a moving direction of a substrate, each of the spray pipelines is provided with several spray ports configured to direct liquid in the spray pipeline towards a surface to be cleaned of the substrate, and one end of each of the spray pipelines is provided with a transmission gear coaxially fixed thereto; a driving system (4) coupled with the transmission gear and thus configured to drive the spray pipeline, through the transmission gear, to rotate reciprocally at the same frequency, wherein a portion of spray pipelines have a reciprocal rotation direction opposite to that of the other portion of spray pipelines. This substrate cleaning device enables a better cleaning effect for the substrate surface with minimum influence on the traveling speed of the substrate.
