1. A TFT-LCD float glass substrate processing line, which is sequentially divided into a precision cutting and edge grinding working area, a surface grinding working area, and an inspection and packaging working area according to process characteristics and areas, wherein,
in the precision cutting and edge grinding working area, precision processing and cleaning are performed on an edge of a glass substrate; in the surface grinding working area, precision processing and cleaning are performed on a surface of the glass substrate; and in the inspection and packaging working area, inspection, judgment, and packaging are performed on the glass substrate after the precision processing;
wherein a cold-end cutting device in the precision cutting and edge grinding working area identifies an area that meets inspection standards and an area that does not meet the inspection standards and the area of the glass substrate which meets the inspection standards is cut into a required standard 8.5 generation/10.5 generation/11 generation semi-finished glass substrate;
wherein a surface grinding device in the surface grinding working area repairs a surface of the glass substrate for three times; and
wherein a first surface inspection machine device in the surface grinding working area performs automatic detection and judgment on the surface of the glass substrate, which is divided into three levels: a severely unqualified product, a slightly unqualified product, and a qualified product, the severely unqualified product is transmitted to an waste area of the cold-end cutting device for unloading through an automatic transmission device in the inspection and packaging working area, the slightly unqualified product is transmitted back to an bonding machine entry conveyor belt in the surface grinding working area through the automatic transmission device for re-bonding and re-grinding.
