Specific embodiment
The present invention is further expalined with specific embodiment below, but the guarantor being not intended to restrict the invention
Protect range.
In the past in vacuum glass making and the edge sealing course of work is carried out, in order to realize the sealing-in between upper and lower sheet glass,
It needs upper and lower sheet glass being placed into heating furnace and carries out whole heating, then the glass by being set on upper and lower sheet glass
After the melting of glass powder, by upper and lower sheet glass sealing-in, the space occupied is big in entire edge sealing work, and consumption of calorie is more, and operates tired
Difficulty, the period is long, low output, can not meet demand growing day by day on the market, and to solve the above-mentioned problems, the present embodiment carries
A kind of edge bonding method of vacuum glass is supplied, in this method, mainly by high hot wind to needing to carry out the vacuum glass side of edge sealing
Side carries out local emphasis heating, specific as follows to reduce the consumption of heat similar to the heating process and principle of Blowing drum：
I）The side of the pre- sealing-in of vacuum glass is positioned over to the side of high hot air source, opens high hot air source, be hot wind via
Pre- sealing-in side is blown away to vacuum glass direction, final to realize to realize that the side to vacuum glass carries out local emphasis heating
Vacuum glass is successively decreased in gradient from pre- sealing-in side to center position elongating temperature, to effectively prevent the phenomenon that glass is by thermal breakage
It generates；
II）When heating side edges to the molten condition of the pre- sealing-in of the vacuum glass, in upper piece glass of the vacuum glass
Sealing part implantation glass liquid between glass and lower sheet glass simultaneously smoothes out, and cools down, and edge sealing is completed, since glass is only in the shape of melting
Can just realize mutual bonding under state, and fastness is high, therefore, it is necessary to by the heating side edges of the pre- sealing-in of vacuum glass to molten
Melt state.
Wherein, the upper sheet glass and lower sheet glass can select simple glass or tempered glass.
If the direct higher hot wind of temperature in use heats the side of vacuum glass, glass rupture can also occur
Phenomenon,, can be by step I as the improvement of technical solution in order to improve yield rate）Middle heating source is to the vacuum glass side
Mode of heating selects segmented laser heating, is specifically divided into：Three low-temperature prewarming, medium temperature heating and high-temperature heating continuous ranks
Section, wherein, the temperature of the low-temperature prewarming is 50 ~ 200 DEG C, the temperature of medium temperature heating is 200 ~ 600 DEG C, the high temperature adds
The temperature of heat is 600 ~ 1000 DEG C.
It, can be by step I in order to realize large-scale production and the flow work）The position of middle heating source is fixed, by vacuum
Glass is moved relative to the heating source, realizes the heating for pre- sealing-in side, can be incited somebody to action in practical production process true
Empty glass is positioned on transmission belt, and the side of conveyer belt or top are provided with heating source, is realized by the transmission of conveyer belt true
Empty glass completes the local heating for vacuum glass relative to the movement of heating source.
In order to further reduce the probability of glass rupture, as the improvement of technical solution, the step II）The glass of middle injection
Glass liquid is heated for cryogenic glass powder, and the temperature of the glass metal is less than/is equal to the side of the pre- sealing-in of the vacuum glass
Temperature, so as to effectively avoid bursting for glass.
Introduce the detailed process that vacuum glass making is carried out using above-mentioned edge bonding method again below, it is specific as follows：
1）Upper sheet glass and lower sheet glass are cut, and clean up according to specification, it is spare；
2）Supporter dot matrix is laid in the side of lower sheet glass, and the surrounding of lower sheet glass is provided with glass binder,
The preferred high-temperature plastic of the binding agent；
3）The upper sheet glass is withheld in the top of the lower sheet glass, by the glass binder by it is described upper piece
The surrounding of glass and the lower sheet glass bonds, and forms one；
4）The side of the upper sheet glass and the pre- sealing-in of lower sheet glass is positioned over to the side of heating source, is added
Heat, wherein, the heating source is hot wind；
5）When heating side edges to the molten condition of the pre- sealing-in, the envelope on described between sheet glass and lower sheet glass
Mouthful place and smoothes out implantation glass liquid, cools down, completion edge sealing；
6）Medical needle, one end of the medical needle and institute are inserted at the edge sealing of sheet glass and lower sheet glass on described
It states the sealing space formed between sheet glass and lower sheet glass to communicate, the other end is connected with vacuum pump, to the sealing space
It is vacuumized；
7）After vacuumizing, the medical needle is blocked using electric arc welding device, and solder joint is formed in the truncated position,
It is blocked at the solder joint using the glass metal of molten condition, the electric arc welding device can select laser electric arc welding device.
Wherein, step 6）In for convenience medical needle insertion, can be in advance in upper sheet glass and the edge sealing of lower sheet glass
Place's drilling, the medical needle at the aperture by being inserted into.
The present embodiment provide to the method that vacuum glass vacuumizes extracted by medical needle, and be
It is inserted into, is blocked after vacuumizing by electric welding machine, then blocked by molten glass metal, in appearance at the sealing-in of upper and lower glass
The position of syringe needle is can't see, and since medical syringe needle is thinner, can avoided to causing the very big hole to cause to leak at sealing-in
The phenomenon that gas, occurs, and ensures the vacuum degree of vacuum glass well, and avoids previous vacuum glass on the glass of side
It stays there are one hole is vacuumized, by metal cap closure on hole, difficulty is brought to transport and construction.
Wherein, it is conducted heat due to vacuum glass centre and is made of radiant heat transfer and supporter heat transfer, in order to further drop
The hot/cold conduction of the low vacuum glass, it is preferable that above support is sphere, is that point connects with upper sheet glass and lower sheet glass
It touches, effectively reduces hot/cold conduction, more preferably, the sphere is micro- steel ball or glass microballoon.
In order to which upper sheet glass and can either can connect with bottom sheet glass bonding with supporter, as technical solution should, make
The step 2）The height of the relatively upper sheet glass of middle glass binder is more than the height of the relatively upper sheet glass of above support, due to
Glass binder has certain elasticity, and when upper sheet glass is withheld above lower sheet glass, the height of glass binder can drop
It is low, the very good quality that can be in contact with supporter, improve vacuum glass of sheet glass is gone up at this time.
It is consistent with edge bonding method, preferably described step 4）Middle heating source seals the upper sheet glass and the lower sheet glass in advance
The heating side edges mode connect is segmented laser heating, specially：Three low-temperature prewarming, medium temperature heating and high-temperature heating continuous ranks
Section, wherein, the temperature of the low-temperature prewarming is 50 ~ 200 DEG C, the temperature of medium temperature heating is 200 ~ 600 DEG C, the high temperature adds
The temperature of heat is 600 ~ 1000 DEG C.
