Display panel manufacturing device and cleaning method

A cleaning method applied to a display panel manufacturing device, the display panel manufacturing device comprising:

• a machine table, configured to support and deliver a glass substrate;
• a working pipeline, arranged in a first direction of the machine table and configured to convey a material to act on the glass substrate;
• a gas supplier, communicating with the working pipeline via a gas supply pipeline;
• and
• a liquid supplier, communicating with the working pipeline via a liquid supply pipeline,
• wherein there is disposed a detector on the machine table that is configured to detect a state in which the glass substrate is delivered on the machine table;
• a first automatic valve is disposed in the gas supply pipeline;
• a second automatic valve is disposed in the liquid supply pipeline;
• and the detector is coupled with the first automatic valve and the second automatic valve;
• and
• the cleaning method comprises:
• detecting, by the detector, an operating state of the machine table and outputting control signals;
• and
• controlling the first automatic valve and the second automatic valve to be opened or closed according to the respective control signals for the first automatic valve and the second automatic valve;
• wherein a vertical distance from one end of the working pipeline adjacent to the machine table to the machine table is greater than a thickness of the glass substrate;
• a baffle plate dividing the working pipeline into two independent pipelines is arranged inside the working pipeline so that the working pipeline comprises a first pipeline and a second pipeline;
• wherein there is defined an air blade port in a side of the first pipeline adjacent to the machine table;
• and wherein there is defined a group of through holes in a side of the second pipeline adjacent to the machine table.
