A method for sealing flat vacuum glass, comprising: in a vacuum chamber, heating a pre-assembled part including flat glass, a sealing material and a support, and simultaneously evacuating the vacuum chamber to remove gas inside the pre-assembled part , and then apply pressure perpendicular to the horizontal direction of the glass to the pre-assembled parts to achieve sealing, and finally cool and solidify to obtain a sealed flat vacuum glass. This method is a one-step process. Pressure is applied in the vacuum chamber to make the material flow to form a stable structure and heat to seal, so that the sealing and vacuuming can be carried out at the same time. Compared with the traditional technology, the production efficiency is improved. When the sealing material is softened, the hot pressing process is used to make the material flow to a certain extent to form a stable structure that avoids stress concentration, and the yield is higher than that of traditional technology.
