Embodiment 1

[0053] (1) Cut, edge and clean the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-emissivity glass, high visible light transmittance glass and so on.

[0054] (2) Use a mechanical drill or a laser drilling machine to make a vent hole with a diameter of 2mm on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the rear substrate glass.

[0055] (3) Make isolation support points on the rear substrate glass by screen printing. Use amorphous low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a coefficient of thermal expansion slightly smaller than that of the glass panel and an organic solution to prepare a rheological slurry suitable for screen printing. Then use the screen printing method to print wet film dots with a diameter of about 0.5mm and a thi...

Embodiment 2

[0063] (1) Cut, edge and clean the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-emissivity glass, high visible light transmittance glass and so on.

[0064] (2) Use a mechanical drill or a laser drilling machine to make a vent hole with a diameter of 1mm on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the rear substrate glass.

[0065] (3) Make isolation support points on the rear substrate glass by screen printing. A slurry with rheological properties suitable for screen printing is prepared by using amorphous low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a thermal expansion coefficient slightly smaller than that of the glass panel and an organic solution. Then use the screen printing method to print wet film dots with a diameter of ab...

Embodiment 3

[0073] (1) Cut, edge and clean the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-emissivity glass, high visible light transmittance glass and so on.

[0074] (2) Use a mechanical drill or a laser drilling machine to make an exhaust hole with a diameter of 3mm on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the rear substrate glass.

[0075] (3) Make isolation support points on the rear substrate glass by screen printing. A slurry with rheological properties suitable for screen printing is prepared by using amorphous low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a thermal expansion coefficient slightly smaller than that of the glass panel and an organic solution. Then use the screen printing method to print wet film dots with a diameter o...

Abstract

This invention discloses novel method and apparatus for producing vacuum glass. The method comprises: producing isolated supporting points between glass panels and airtight sealing layers at the edges of glass panels by screen printing process, sealing the edges, exhausting, sealing the exhaust mouth, baking, examining, and framing. The softening temperature and thermal and mechanical properties of the low-melting-point glass used for isolated supporting points and airtight sealing layers, and the thickness of isolated supporting points should precisely match the thickness of airtight sealing layers. The exhaust and sealing apparatus comprises: a sealed vacuum chamber for fixing the surface of the vacuum glass panel with exhaust holes downward onto the sealing table, and a movable ejection pin with an electric heating device below the exhaust holes; or a bell jar with a sealing ring, and movable ejection pin with an electric heating device below the exhaust holes. After exhausting, the ejection pin heats the metal plate sintered with low-melting-point glass to the sealing temperature of the low-melting-point glass, and seals by tip layering onto the exhaust holes.

Description

Technical field [0001] The present invention relates to a new method and device for preparing vacuum glass panels. Vacuum glass panel refers to the relative placement of two or more pieces of glass with intervals, and a number of small isolation support point arrays are set between the glass pieces. After exhaust sealing, the glass pieces are formed between the pieces. Vacuum airtight cavity, a transparent material with excellent heat insulation and sound insulation properties is obtained. It is used in multiple technical fields such as buildings, transportation vehicles, and refrigeration appliances. In the manufacturing process of the vacuum glass panel, after the sealing of the peripheral parts of the vacuum glass panel is completed, the air in the gap between the glass sheets needs to be removed and the vacuum state must be maintained, and the exhaust air must be sealed. The present invention mainly relates to A new method for making isolation support points between vacu...
