After vacuuming, the intracavity pressure fixture assembly 7 is activated to buckle the upper carrier and the lower fixture, and the vacuum upper cavity 61 and the intracavity pressure fixture assembly 7 rise at the same time, and the vacuum cavity synchronous belt line 3 conveys the carrier to the board outlet synchronous belt line 4 and sends it to the next workstation.

[0016] In a specific embodiment, the vacuum upper chamber assembly 6 includes an upper chamber lifting cylinder 62 and a vacuum upper chamber 61 that cooperate with each other; wherein the upper chamber lifting cylinder 62 is fixed on the upper platen 11 of the machine 1, and the vacuum upper chamber 61 is installed at the movable end of the upper chamber lifting cylinder 62 and is driven by it to lift and dock with the vacuum lower chamber 5.
