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
The invention belongs to the vacuum glass field, especially a kind of automatic edge sealing process for vacuum glass.
Background technology
The sound insulation of vacuum glass, heat insulation, heat-insulating property are better than simple glass or laminated glass greatly, and its application prospect is boundless.Traditional vacuum glass method for packing is to place an extraction pipe between the adjacent two layers glass edge respectively, utilizes this extraction pipe to connect negative pressure generator and introduces negative pressure to each vacuum chamber, and the scorification extraction pipe carries out the sealing-in of each bleeding point then.The defective of this structure is: 1. oversize, inefficiency of pumpdown time, and extraction pipe must scorification; 2. on each vacuum chamber on the vacuum glass finished product, all can retain the extraction pipe of one section scorification, very not attractive in appearance and frangibility; 3. stay next extraction pipe between the adjacent glass at least, all there is gas leakage hidden danger in each extraction pipe, more is not easy to carrying and construction, causes the rising of scrap rate; 4. whole complex process, bad operation, cost is very high.Above-mentioned various defective has had a strong impact on being extensive use of of vacuum glass, has hindered further developing of vacuum glass.
To sum up, the comparatively complicated pumpdown time of the manufacturing process of existing vacuum glass is oversize and unreasonable, and production efficiency is lower, and scrap rate is higher, and cost of manufacture is bigger, and selling price is higher, has influenced the production of vacuum glass, has restricted the widespread use of vacuum glass.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, simple in structure, good, the attractive in appearance molten certainly a kind of automatic edge sealing process for vacuum glass of edge sealing resistance to air loss is provided.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of automatic edge sealing process for vacuum glass, being included in upholder is set on the base plate glass, will go up sheet glass is placed on the base plate glass, adopts the glass powder with low melting point edge sealing between last sheet glass and base plate glass, puts into the vacuum furnace internal heating, takes out acquisition vacuum glass finished product work step, wherein in glass powder with low melting point edge sealing work step, glass powder with low melting point type bar or glass powder with low melting point be stacked on the base plate glass and and base plate glass, go up formed cavity between the sheet glass leaves effusion air when vacuumizing in process furnace gap.
And described glass powder with low melting point type bar can be made into porous or spination bar or straight flange type, square type bar, circular type bar or trilateral type bar.
And, described gap be glass powder with low melting point type bar or glass powder with low melting point heap with last sheet glass between formed gap, perhaps make on glass powder with low melting point type bar or the glass powder with low melting point heap connection base plate glass, on the gap of formed cavity between the sheet glass.
And, described make on the glass powder with low melting point type bar be communicated with base plate glass, between the sheet glass gap of formed cavity be grooved, half slot, manhole or interrupted section.
And, described gap is for making angle of declination, the low melting glass type bar of putting or the gap between glass powder with low melting point and the last sheet glass between the angle of declination position of last sheet glass and base plate glass on the last sheet glass, perhaps low melting glass type bar or or glass powder with low melting point heap on the gap of making, or last sheet glass is poor less than descending sheet glass and forming the limit, on the limit differs from, stack glass powder with low melting point or vermicelli, and keep leaving certain clearance between last sheet glass and the low glass powder.
Advantage of the present invention and beneficial effect are:
1. this automatic edge sealing process for vacuum glass adopts hot melt negative pressure self-priming mode from the sealing by fusing limit, and edge sealing is effective, and edge sealing does not have vestige, and edge sealing is attractive in appearance, has stopped gas leakage hidden danger, has greatly shortened the time of bleeding and has improved work efficiency.
2. these many automatic edge sealing process for vacuum glass adopt certainly molten mode edge sealing voluntarily, are beneficial to the carrying construction, and technology is simple, the production efficiency height, and the level of automation height is particularly suitable for industrialization, mass-producing, standardized production.
3. this automatic edge sealing process for vacuum glass adopts multiple packaged types such as glass powder with low melting point type bar, glass powder with low melting point heap, and the sealing-in of bleeding is reliable, has effectively improved the total quality level of vacuum glass.
4. one-piece construction of the present invention is simple; the encapsulation of bleeding voluntarily is reliable; resistance to air loss is good, and gas leakage hidden danger is few, good looking appearance; more traditional time of bleeding shortens 2-10 times; simplify manufacture craft, improved the work-ing life of vacuum glass, reduced the breakage rate of vacuum glass; greatly promote the vacuum glass industrial expansion, be particularly suitable for industrialization, mass-producing, the standardized production of vacuum glass.
