Since the flange is separated at the beginning of the heating stage, it is necessary to ensure that the flange can be accurately docked after the heating is completed to prevent deviations in the docking and the occurrence of local red leakage in the flange docking area, thereby achieving stability in the heating process of the substrate glass line.
