Embodiment 1

[0039] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the method for manufacturing and sealing the exhaust port 3 in the vacuum glass of the present invention includes a process of making the exhaust port 3 in the vacuum glass, a process of making the glass sealing plug 4 and a process using the described glass sealing plug 4. The process of sealing the exhaust port 3. In the process of making the exhaust port 3 in the vacuum glass, the laser is used to directly engrave the through hole layer by layer in the flat glass to form a through hole. In the process of sealing the plug 4, a laser is used to three-dimensionally engrave a plug body on the glass block, the shape of the plug body matches the shape of the through hole, and the glass sealing plug 4 is used to seal the exhaust port 3 During the process, the plug body is put into the through hole, the sealant 5 is laid between the plug body and the through hole, and then the plug body and the t...

Abstract

The invention relates to a method for manufacturing and sealing an exhaust port in vacuum glass, which comprises the following steps: directly carrying out layer-by-layer three-dimensional carving in plate glass by using laser so as to form the exhaust port, carrying out three-dimensional carving on a glass block by using laser so as to form a glass sealing plug, laying sealant between the plug body and the exhaust port, then welding and sealing the plug body and the exhaust port by using laser. The invention also provides a system for manufacturing and sealing the exhaust port in the vacuum glass, which comprises a laser carving device, a laser welding device, a vacuum chuck and a glass sealing plug installing device, wherein the laser carving device comprises a laser device, a laser power controller, a first galvanometer system and a computer; the laser welding device comprises a laser system and a second galvanometer system; the vacuum chuck is connected with a vacuum pump through a connecting tube; a magnet coil is arranged on the top of the vacuum chuck; and the glass sealing plug installing device is composed of a magnet driving device. The sealing exhaust port in vacuum glass of the invention has the advantages of high sealing accuracy and no surface embossment so as to improve vacuum sealing performance and safety performance, and is easy for on-line implementation so as to improve work efficiency.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to optical technology, in particular to laser processing technology, and in particular to a method and system for manufacturing and sealing an exhaust port in vacuum glass. Background technique: [0002] Vacuum flat glass has excellent heat insulation and sound insulation properties, much better than the widely used insulating glass at present, and is the best energy-saving glass. Vacuum flat glass is made by evacuating the gap between two pieces of glass welded and sealed around them into a vacuum state. The gap between the two pieces of glass is very small, only 0.1-0.3mm. In order to make the glass withstand the external atmospheric pressure in a vacuum state, many supports need to be placed between the two pieces of glass. At present, the vacuum glass produced at home and abroad is The diameter of the support is 0.3-0.6mm, made of metal sheet, and the shape is round, ring, C-shaped, squ...
