The utility model provides a manufacturing device for a glass baseplate, which can prevent a clarification pipe from drooping towards gaseous phase space. The manufacturing method for manufacturing the glass baseplate comprises the following steps: the process of melting glass raw material in a melting furnace to form a piece of molten glass; the process of supplying the molten glass for the clarification pipe made of platinum or platinum alloy to clarify the molten glass; and the process of molding the clarified molten glass to form the glass baseplate, wherein in the clarification pipe, the molten glass flows in a manner that the gaseous phase space is arranged at the upper part of the flow path of the molten glass; an air pipe for being communicated with the gaseous phase space and outside air is arranged on the clarification pipe, and protrudes towards the outer side of the clarification pipe in a flue pipe shape on the outer wall surface of the clarification pipe; and a clarification pipe shape variation preventing device is arranged on the air pipe, and is used for preventing the section of the clarification pipe contacted with the gaseous phase space from drooping towards the gaseous phase space when the clarification pipe is heated. |
