The vacuum glass edge sealing device can be used for sealing the edge of glass while vacuumizing, improves the working efficiency, and divides the inner cavity of the vacuum glass into the grids, so that when the vacuum glass is damaged at one position, the continuous use of other parts is not influenced, and the vacuum glass is not provided with the vacuum cap, so that the attractiveness of the vacuum glass is ensured, and the integral strength and the safety of the structure are improved.
Description
Technical Field
The invention relates to the field of conveying laminated glass, in particular to vacuum glass.
Background
In order to improve the safety of glass, laminated glass formed by laminating glass is generally used. Because the existing laminated glass is far lower than vacuum glass in the aspects of heat insulation, sound insulation and the like, the best safety glass still adopts the vacuum laminated glass. And the inside of general vacuum doubling glass only supports the thing, but when a position of vacuum glass damaged, effect such as noise insulation just can not played in general to vacuum glass, needs to change monoblock vacuum glass, and is very extravagant.
Disclosure of Invention
The invention aims to provide vacuum glass, which solves the problems that when one part of the vacuum glass is damaged, the vacuum glass generally cannot play a role in sound insulation and the like, and the whole piece of vacuum glass needs to be replaced, so that waste is caused.
In order to solve the technical problems, the invention adopts the following technical scheme:
the invention relates to vacuum glass, which comprises upper glass and lower glass, wherein four edges of the upper glass and the lower glass are vertically aligned and are in heating melting sealing connection through an outer EVA hot-melt film, an inner EVA hot-melt film is arranged in a cavity formed between the upper glass and the lower glass, the cavity is divided into a plurality of independent grids by the inner EVA hot-melt film, the grids are sealed and separated through the heating melting of the inner EVA hot-melt film, and a plurality of supporting pieces are further arranged in the cavity.
Further, the support member is a D-printed transparent cylinder.
Furthermore, the height of the outer EVA hot melt adhesive sheet and the height of the inner EVA hot melt adhesive sheet which are not melted are both larger than the supporting piece.
Further, the method comprises the following specific steps:
A. putting a vacuum bag into the vacuum cavity, and then flatly laying the lower glass in the vacuum bag;
B. laying an inner EVA hot-melt adhesive sheet with holes on the upper surface of the lower glass, forming the inner EVA hot-melt adhesive sheet into a grid shape, and erecting a plurality of supporting pieces on the upper surface of the lower glass;
C. covering the upper glass above the lower glass, aligning the four sides of the upper glass respectively, and supporting the upper glass by utilizing an inner EVA hot melt adhesive sheet;
D. an outer EVA hot-melt adhesive sheet is arranged between the corresponding edges of the upper glass and the lower glass, and the height of the outer EVA hot-melt adhesive sheet is smaller than that of the inner EVA hot-melt adhesive sheet and larger than that of the supporting piece;
F. then starting a vacuum cavity, starting vacuumizing and continuously heating until the temperature is 140 ℃, stopping heating, and keeping the temperature for 2-3 hours;
G. stopping heating, closing the vacuum cavity, and removing the vacuum bag after the room temperature is recovered. .
Compared with the prior art, the invention has the beneficial technical effects that:
the vacuum glass edge sealing device can be used for sealing the edge of glass while vacuumizing, so that the working efficiency is improved, the internal cavity of the vacuum glass is divided into the grids, when the vacuum glass is damaged at one position, the continuous use of other parts is not influenced, and the vacuumizing is not required to be reserved for vacuumizing, so that a vacuum cap is not arranged on the vacuum glass, the attractiveness of the vacuum glass is ensured, and the overall strength and the safety of the structure are improved.

FIG. 2 is a side sectional view of a vacuum glass according to the present invention;
description of reference numerals: 1. glass is coated; 2. glass is put; 3. an outer EVA hot melt adhesive sheet; 4. a cavity; 5. an inner EVA hot melt adhesive sheet; 6. grid section; 7. and a support member.
Detailed Description
As shown in fig. 1-2, a vacuum glass comprises an upper glass 1 and a lower glass 2, wherein four edges of the upper glass 1 and the lower glass are aligned up and down and are connected in a sealing manner by an outer EVA hot-melt film 3 through heating melting, an inner EVA hot-melt film 5 is arranged in a cavity 4 formed between the upper glass 1 and the lower glass 2, the cavity 4 is divided into a plurality of independent grids 6 by the inner EVA hot-melt film 5, and the grids 6 are sealed and isolated through heating melting of the inner EVA hot-melt film 5.
The height of the outer EVA hot melt film 3 and the height of the inner EVA hot melt film 5 which are not melted are both larger than the supporting piece 7, the height of the inner EVA hot melt film 5 which are not melted is larger than the height of the outer EVA hot melt film 3, and the inner EVA hot melt film 5 is provided with a vent hole. When heating and vacuumizing are carried out, air in the grid is pumped out through the vent hole, and because the height of the inner EVA hot-melt adhesive sheet 5 which is not melted is larger than that of the outer EVA hot-melt adhesive sheet 3, the air in the grid has time to escape.
A plurality of support members 7 are also provided within the cavity 4. The support 7 is a transparent cylinder for 3D printing.
The production process of the vacuum glass comprises the following specific steps:
A. putting a vacuum bag into the vacuum cavity, and then flatly laying the lower glass in the vacuum bag;
B. laying an inner EVA hot-melt adhesive sheet with holes on the upper surface of the lower glass, forming the inner EVA hot-melt adhesive sheet into a grid shape, and erecting a plurality of supporting pieces on the upper surface of the lower glass;
C. covering the upper glass above the lower glass, aligning the four sides of the upper glass respectively, and supporting the upper glass by utilizing an inner EVA hot melt adhesive sheet;
D. an outer EVA hot-melt adhesive sheet is arranged between the corresponding edges of the upper glass and the lower glass, and the height of the outer EVA hot-melt adhesive sheet is smaller than that of the inner EVA hot-melt adhesive sheet and larger than that of the supporting piece;
F. then starting a vacuum cavity, starting vacuumizing and continuously heating until the temperature is 140 ℃, stopping heating, and keeping the temperature for 2-3 hours;
G. stopping heating, closing the vacuum cavity, and removing the vacuum bag after the room temperature is recovered.
