Automatic edge sealing process for vacuum glass

Abstract

The invention relates to an automatic edge sealing technology for vacuum glass, which comprises the following steps of arranging supporters on basal board glass, arranging upper plate glass on the basal board glass, using low melting-point glass powder between the upper plate glass and the basal board glass for sealing edges, placing the upper plate glass and the basal board glass into a vacuum heating furnace to be heated and taking out upper plate glass and the basal board glass to get a finished vacuum glass, wherein in the step of using the low melting-point glass powder for sealing the edge, a section bar of low melting-point glass powder or the low melting-point glass powder is arranged on the basal board glass, and a gap of air escaping in the evacuation in the heating furnace is left in a chamber formed between the basal board glass and the upper plate glass. The invention has simple integrated structure, greatly shortens the evacuation time, increases the work efficiency, has reliable automatic evacuation and sealed package, good air tightness, little air leakage hazard, attractive appearance and production technology simplification, greatly promotes the development of the vacuum glass industry, and is particularly suitable for the industrialized, the scale and the standardized production of the vacuum glass.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to an automatic edge sealing process for vacuum glass. Background technique [0002] The sound insulation, heat insulation and thermal insulation properties of vacuum glass are much better than ordinary glass or laminated glass, and its application prospect is very broad. The traditional vacuum glass packaging method is to place a suction pipe between the edges of two adjacent layers of glass, use the suction pipe to connect the negative pressure generator to introduce negative pressure into each vacuum cavity, and then melt the suction pipe to carry out each suction port. of sealing. The disadvantages of this structure are: 1. The vacuuming time is too long, the work efficiency is low, and the exhaust pipe must be melted; 2. There will be a section of melted exhaust pipe on each vacuum chamber of the vacuum glass product. It is very unsightly and easy to break; 3. At least one exhaust...

AI Technical Summary

Problems solved by technology

The disadvantages of this structure are: 1. The vacuuming time is too long, the work efficiency is low, and the exhaust pipe must be melted; 2. There will be a section of melted exhaust pipe on each vacuum chamber of the vacuum glass product. It is very unsightly and easy to break; 3. At least one exhaust pipe is left between adjacent glass, and each exhaust pipe has a hidden danger of air leakage, which is not convenient for handling and construction, resulting in an increase in the scrap rate; 4. The whole process is complicated , not easy to operate, high cost

The above-mentioned various defects have seriously affected the wide use of vacuum glass and hindered the further development of vacuum glass

[0003] To sum up, the existing vacuum glass manufacturing process is relatively complicated, the vacuuming time is too long and unreasonable, the production efficiency is low, the scrap rate is high, the production cost is high, and the sales price is high, which affects the production of vacuum glass and restricts Wide application of vacuum glass
