Mode 2
    [00039] Figure 4 and figure 5 illustrate embodiment 2 of the invention.

    [00041] The cover plate 11, the bottom plate 13 and the annular side wall 14 are made of metallic materials; the partition plate 12 is made of PP (polypropylene), PC (polycarbonate) or other non-metallic material with adequate hardness; and the heating device 23 is an induction heating device.
    [00042] Taking the vacuum glass of the two layers as an example, in the same way, when modality 2 of the present invention works, as illustrated in figure 4, firstly, the assembly of an upper glass plate 19 and a lower glass plate 20, then placing the mounted glass plates inside the first closed space 15, simultaneously applying vacuum to the first and second closed spaces, and after the first closed space reaches the required vacuum level, disassemble the partition device 18 so that the upper glass plate is supported on an intermediate support 21 and mounted in a state to be sealed; secondly, in the maintenance state of the first vacuum closed space (that is, maintain the vacuum degree of the first closed space), increasing the air pressure of the second closed space until it communicates with the atmosphere and dismantling the cover plate 11 , where as illustrated in figure 5, the partition plate 12 is supported on the surface of the upper glass plate 19 under the action of the pressure difference on both sides by the pressure of an expansion joint 22 to deform and the atmospheric pressure is applied to the glass plates to be sealed; and, finally, heating the parts to be sealed of the glass plates to be sealed by using a heating device 23 from outside the partition plate 12, and completing the air-tight seal on the periphery of the glass plates to be sealed by a metal welding process.

As illustrated in the figures, an expansion joint 22 'of a wave-shaped section structure is adopted in mode 3; and compared to expansion joint 22 in mode 2, expansion joint 22 'of the waveform section structure may have a greater telescopic deformation, so that the partition plate 12 has a greater upward and downward displacement and a full thickness range of vacuum glass wider than can be sealed by the sealing device.
    [00048] Specifically, mode 2 and mode 3 only list expansion joints in two specific ways, and in addition, the expansion joint with zigzag cut shape and other expansion joints with suitable section structures can also be adopted .
    [00049] The modalities can only be used to explain the invention. The modalities of the present invention are not limited to the above modalities. Several specific modalities made by technical personnel in the field and according to the thinking of the present invention are within the protection range of the invention.
