The disclosure discloses a manufacturing method of tempered vacuum glass, comprising the following steps: (1) manufacturing metalized layers, and performing tempering or thermal enhancement on the glass substrates; (2) placing a metal solder on the metalized layers; (3) superposing the glass substrates to form a tempered glass assembly; (4) heating the tempered glass assembly to 60-230° C.; (5) keeping the tempered glass assembly within the heating temperature range of step (4) in a vacuum chamber, and vacuumizing the vacuum chamber to a preset vacuum degree; and (6) hermetically sealing the metalized layers by adopting a metal brazing process. By adopting the manufacturing method of the disclosure, the stress when the two glass substrates are sealed can be greatly reduced, and the connection strength can be increased; moreover, when gas is exhausted within the temperature range, the exhaust efficiency is high, and the exhaust effect is better, vacuum glass with high vacuum degree can be obtained, and the service life of the vacuum glass is prolonged. The disclosure further discloses a tempered vacuum glass production line based on the above mentioned manufacturing method.
