The argon is filled into the hollow glass, so that the heat transfer coefficient U value of a glass system can be effectively reduced, the hollow glass is a very economic and effective energy-saving means, and the hollow glass is widely applied to buildings. The argon filling mode comprises online argon filling and offline argon filling. The on-line argon filling is completed on a hollow glass production line, namely, before two or more glass single sheets are completely bonded through a spacing frame and a sealant, the inner cavity of the glass single sheets is filled with argon and then the glass single sheets are combined, so that the on-line argon filling is realized.
