The invention relates to a vacuum closing forming device for cementing a foam sandwich structure of a large-area aluminum panel and a cementing method of the vacuum closing forming device in the technical field of cementing. The vacuum closing forming device comprises a vacuum tank, a buffer tank, a pipeline assembly, a valve assembly, a synchronous lifting mechanism and a vacuum bag. According to the vacuum closing and forming device for foam interlayer common bottom glue joint, through the optimal design of the vacuum tank, the buffer tank, the synchronous lifting mechanism and the vacuum bag assembly, the interior and the exterior of an interlayer common bottom can be vacuumized to preset pressure at the same time, and then gas in the glue joint face is exhausted under the condition that a panel is not subjected to air pressure; and then the panel is folded, so that the glue joint defect caused by air entrained in the glue joint surface is avoided, the deformation of the panel is reduced ...
