Description
Technical Field

Background
Vacuum glass is a novel glass deep processing product, which is energy-saving, sound-insulating and the likeThe face has good use effect and good development potential and prospect. Vacuum glass is a glass product in which two or more sheets of glass are separated by a support, the peripheries of the glass are sealed, and a vacuum layer is formed between two adjacent sheets of glass. Vacuum sealing is a very important link in the preparation process of vacuum glass. The vacuum sealing is to pump out the air between two adjacent glass sheets to form a vacuum cavity, and then seal with specific materials to make the vacuum degree in the vacuum cavity smaller than 10 -1 Pa. If the sealing quality is poor, the extraction opening cannot be completely blocked, and external gas can gradually enter the vacuum cavity through the extraction opening, so that the vacuum degree of the vacuum glass is increased, and finally, the vacuum glass is restored to 1 atmosphere pressure, and under the condition, the product can lose the characteristics of the vacuum glass.

The glass bead seal is more mature than the high-temperature seal of a glass tube, and the seal glass bead is made of sealing glass materials and is generally cylindrical or round bead with a through hole. When in use, the sealing glass beads are fixed at the air extraction holes of the vacuum glass, after the air exhaust is completed, the workpiece and the glass beads are heated, so that the air extraction holes are sealed after the glass beads are melted, but the expansion coefficient of the existing glass beads is larger than that of the sealing glass, and the glass beads are brittle materials and are not generally suitable for manufacturing and producing the vacuum glass.

In the vacuum glass sealing device, a counter bore design is adopted at the sealing position of the vacuum glass 100 (namely, the second extraction opening 300 of the vacuum glass 100 is a through hole concave towards the direction of the cavity 200), so that the sealing piece 15 cannot be higher than the surface of the vacuum glass 100 after sealing, the sealing position cannot be damaged in the carrying process, and the permanence of the vacuum effect is ensured.
5. The vacuum glass sealing device does not need to heat or exhaust air in large equipment, can save time, and has the advantages of energy conservation and environmental protection.
6. The vacuum glass sealing device has low requirements on equipment tools, and the required equipment has low production cost and is suitable for popularization and use.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this invention, and are intended to be within the scope of this invention.
