Vacuum glass sealing method and device

摘要

The present invention discloses a vacuum glass sealing method and a sealing device using the method. The sealing device comprises a bottom plate, an annular side wall, a cover plate, a partition plate and a heating device, wherein the lower end of the annular side wall is situated on the bottom plate and air-tightly connected with the bottom plate; the cover plate is air-tightly covered at the upper end of the annular side wall; the partition plate is arranged on the middle part of the height direction of the annular side wall; after the periphery of the partition plate is air-tightly connected with the inner surface of the annular side wall, the partition plate divides the space encircled by the bottom plate, the annular side wall and the cover plate into a first closed space and a second closed space; and the two closed spaces are provided with an air extraction port for vacuumizing respectively.

主权项

1. A vacuum glass sealing method, comprising the following steps of:
(1) Taking a bottom plate, an annular sidewall, a cover plate, and a partition plate as a common side wall, and forming a closed space on two sides of the partition plate respectively; (2) Assembling a plurality of glass plates according to a corresponding relationship when the vacuum glass is formed, arranging a middle support for forming a vacuum space on at least one of every two adjacent glass plates, and inserting a movable partition device during assembly so that a big enough interval is formed between the every two adjacent glass plates to ensure high enough conductance between the two adjacent glass plates high enough and enable the air molecules to successfully escape during vacuumizing; (3) Putting the assembled glass plates into one of the closed spaces, and simultaneously vacuumizing the two closed spaces in a state that the partition plate and the glass plates are kept in a separate state or the partition plate does not apply any pressure to the glass plates till the closed space of the glass plates achieves the required vacuum degree; (4) Dismantling the movable partition device, and making the every two adjacent glass plates propped on the middle support amid and assembled in a to-be-sealed state; (5) In the state of keeping the closed space of the glass plates vacuumized, increasing the air pressure of the other closed space so that the partition plate is deformed under the action of pressure difference of two sides and propped on the surface of the glass plates to be sealed, and then applying pressure to the glass plates to be sealed; (6) Heating the parts to be sealed of the glass plates to be sealed by using a heating device from the exterior of the closed space of the glass plates to be sealed, and completing air-tight sealing on the periphery of the vacuum glass by a metal welding process, wherein the used heating device is an inductive heating device or a microwave heating device.
