Abstract
Provided is a vacuum pumping device and a related method for manufacturing a vacuum glazing. The vacuum pumping device includes: a circular tubular pumping operation unit; a cylindrical pump-out hole sealing operation unit; a control part; and a driving device. The pumping operation unit and the pump-out hole sealing operation unit share a central axis, and form a cylinder with the former being outside and the latter being inside. A pumping channel is formed in a tube wall of the pumping operation unit, and a heating unit is disposed in the top portion inside the pump-out hole sealing operation unit. The control part time-sequentially controls the pumping operation unit and the pump-out hole sealing operation unit to move, controls the pumping channel to perform operations, and controls the heating unit to heat a sealing sheet to perform a pump-out hole sealing operation.
