Embodiment
Relevant detailed description of the present invention and technology contents, conjunction with figs. is described as follows, however appended accompanying drawing only provides reference and explanation usefulness, and the present invention is limited.
Please refer to Fig. 1 and Fig. 2, be respectively vacuum heat-insulation glass of the present invention bleed the method flow synoptic diagram of sintering encapsulation and the three-dimensional appearance synoptic diagram of device; The invention provides the bleed method for packing of sintering of a kind of bleed sintered components and a kind of vacuum heat-insulation glass for vacuum heat-insulation glass.In the present embodiment, vacuum heat-insulation glass sintering packaging system 1 is to utilize one to bleed sintered components 40 and vacuum heat-insulation glass is bled and the sintering packaging operation.
Vacuum heat-insulation glass sintering packaging system 1 of the present invention is to utilize one to bleed sintered components 40 and vacuum heat-insulation glass is bled and the sintering packaging operation, this vacuum heat-insulation glass comprises a lower glass plate 10 and a upper glass plates 20, and this upper glass plates 20 is stacked and placed on this lower glass plate 10 tops, be formed with a cavity volume 100 between this lower glass plate 10 and this upper glass plates 20, and be provided with a plurality of supporters 15 between this lower glass plate 10 and this upper glass plates 20.
Then, offer at least one through hole 21 that is communicated with this cavity volume 100 in this upper glass plates 20, in addition, provide one to seal post 30, this outer edge surface that seals post 30 is coated glass glue 31, and the post 30 that seals that will be coated with glass cement 31 is arranged in this through hole 21.It should be noted that this external diameter that seals post 30 needs the internal diameter less than this through hole 21, so that these through hole 21 ccontaining posts 30 that seal reach the fusion effect to make glass cement 31 through behind the high temperature sintering.
Please also refer to Fig. 3 and Fig. 4, be respectively three-dimensional exploded view and the assembled sectional view of the sintered components of bleeding of the present invention; When carrying out the sintering packaging operation, at first, one sintered components 40 of bleeding is provided, and this sintered components 40 of bleeding comprises that cover is combined in a outer cover 41 on this through hole 21, is contained in a heating unit 42 in this outer cover 41, is arranged on the support pad 43 in this outer cover 41 and is fixed on a pressurizing member 44 (step a) on this support pad 43.
In the above-mentioned sintered components 40 of bleeding, this outer cover 41 is a metal housing, and this outer cover 41 has a bleeding point 411 and a heating gate 412, and this bleeding point 411 is for connecting a vacuum-pumping equipment (not shown), and this heating gate 412 is equipped with a lead 421 that electrically connects this heating unit 42.
Moreover this support pad 43 can be the slide that glass or quartzy material constitute.Again, this heating unit 42 is placed on the top of this support pad 43, seals on the post 30 to carry this heating unit 42 and to be pressed together on this.
This pressurizing member 44 is to be made as a spring, and an end of this spring is replaced this support pad 43, the power of pressing is provided and makes this seal post 30 to being lowered into this cavity volume 100 this is sealed post 30.During actual enforcement, this pressurizing member 44 also can be made as a weight, but enough gravity must be provided, so that this seals the effect that post 30 produces to lower seal.
In present embodiment, this sintered components 40 of bleeding also comprises a soft cushion body 45, and this soft cushion body 45 is folded between this support pad 43 and this upper glass plates 20.Being arranged on of this soft cushion body 45 can increase and this upper glass plates 20 between adaptation, to be easy to keep the formation of vacuum.This soft cushion body 45 is made of rubber, viton (Viton) or silica gel material, it can be a packing ring or a pad, when this soft cushion body 45 is a packing ring, the bottom surface correspondence of this outer cover 41 is made as a fluting 410, on the other hand, when this soft cushion body 45 was a pad, then the bottom surface correspondence of this outer cover 41 was made as a hollow-out parts.
Please continue with reference to Fig. 5 to Fig. 8, be respectively the use synoptic diagram of the sintered components of bleeding of the present invention, the assembled sectional view behind heating synoptic diagram, involution synoptic diagram and the vacuum involution; The post 30 that seals that outer rim is coated with glass cement 31 is arranged in this through hole 21, in addition this sintered components of bleeding is established for 40 groups to finish and be placed in this and seal on the post 30, then carries out vacuum suction.When bleeding, this seals between the glass cement 31 of post 30 and the through hole 21 still has small gap, so the gases in the cavity volume 100 can utilize this small gap to bleed and reach vacuum effectiveness between this lower glass plate 10 and the upper glass plates 20.
After bleeding, when treating that this cavity volume 100 reaches a specific vacuum tightness (10-3torr), this heating unit 42 begins heating, and heats and reach more than 350 ℃, and this seals the glass cement 31 (step b) of post 30 with hot melt.At this moment, this heating unit 42 is the glass cement 31 that this seals post 30 to be heated in the thermal radiation mode by this transparent support pad 43, and continues to keep and bleed to make this glass cement 31 hot melts.Because this pressurizing member 44 is to continue to press this support pad 43, so behind these glass cement 31 hot melts, this seals post 30 and can be subjected to the pressure of this pressurizing member 44 and sink down in this cavity volume 100, and then these through hole 21 (step c) of involution.
Preferably, this seals post 30 is to sink down in this cavity volume 100, replace the inner-wall surface of this lower glass plate 10 up to this bottom surface of sealing post 30, at this moment, this seals post 30 can be simultaneously as the support between this lower glass plate 10 and the upper glass plates 20, to strengthen the structural strength in these cavity volume 100 zones, prolong the vacuum panels life-span.
Referring again to Fig. 9, be bleed three-dimensional appearance synoptic diagram behind the sintering involution of vacuum heat-insulation glass of the present invention; When this seals after post 30 sinks down in this cavity volume 100, this end face that seals post 30 is the surface that flushes this upper glass plates 20, perhaps be lower than these through hole 21 end faces and form a recessed district, make the surface of vacuum glass keep smooth by this, avoiding because of rat in group if transport and collide foreign object in the process, cause vacuum glass to damage and lose original heat-blocking action.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
