Description

Technical Field

[0001] This utility model relates to the field of vacuum glass structure technology, specifically to a glass splicing component and vacuum glass. Background Technology

[0002] As a new generation of energy-saving glass, vacuum glass has been widely used in many industries such as construction and medical care due to its heat insulation and sound insulation properties.

[0003] Currently, some vacuum glass structures, such as Figure 1a , Figure 1b , Figure 1c As shown. Figure 1a The image shown is of a relatively mature vacuum glass, with... Figure 1a For example, the upper glass a1 and lower glass a2, separated by the support a3, are sealed using a direct sealing method such as laser sealing or a sealing material a5 to form a sealed cavity that serves as a vacuum layer a6. An vent is created at an appropriate position on the upper glass a1 (usually near a bottom corner of the glass panel), and an vent pipe a4 (typically 1-2 mm in diameter, with a maximum cross-sectional area of ​​approximately 3 mm²) is installed. 2 The exhaust pipe (a4) is fused into the vent hole, serving as a crucial venting device in vacuum glass manufacturing. A vacuum pump or vacuum furnace extracts gas from the sealed cavity through this exhaust pipe (a4) and seals it, forming a vacuum layer (a6). To protect the exhaust pipe from damage, a protective cap (a8) is installed, and a getter (a7) is placed within the vacuum layer (a6) to absorb residual gases and gases released from the processing materials used (e.g., the inner surface of the glass, supports, or sealing materials).

[0004] like Figure 1b The image shows another relatively mature type of vacuum glass, with... Figure 1b For example, Figure 1b The vacuum glass structure shown is a Figure 1a The vacuum glass structure shown is a further improvement. The difference between the two is that the exhaust pipe a4 is replaced by a sealing piece b8 to seal the exhaust port and also replace the protective cap a8. Figure 1b and Figure 1a Another difference is that the upper and lower glass panes are the same size, aligning the edges, and the solder is located between the upper and lower glass panes, commonly known as "flat edge sealing." Figure 1a The upper glass is slightly smaller than the lower glass, forming a step around the perimeter. Solder 5 is located on the step, commonly known as "offset edge sealing".

[0005] The existing vacuum glass manufacturing process still faces several technical challenges. Firstly, window and door glass comes in various sizes, ranging from 4m x 3m to 0.3m x 0.2m, with thicknesses typically ranging from 3mm to 8mm. Glass is a relatively heavy and brittle material; large panes are heavy and fragile during transport. Furthermore, the diverse sizes of window and curtain wall glass used in architecture necessitate meticulous structural processing on each pane, including drilling, grooving, installing vent pipes, and inserting getters. Additionally, after placing the supports, the holes, grooves, and edges of the upper and lower panes must be aligned, making the process labor-intensive and time-consuming, impacting productivity and yield.

[0006] On the other hand, the use of additional components such as the suction pipe and protective cap (sealing plate) of the venting and sealing device causes its geometric outer edge to protrude from the surface of the upper glass, resulting in inconvenience during transportation, installation, and use. It is particularly prone to breaking the glass, causing the product to lose its vacuum and fail. Furthermore, since the vent must be manufactured before physical tempering, and its distance from the edge of the vacuum glass cannot be too small (usually more than 2.5cm from the edge) to reduce breakage during tempering and facilitate the installation of the vent head during venting, the appearance of the finished vacuum glass is affected by the presence of the vent and getter, resulting in an unsightly appearance (for example, the vent cannot be obstructed by the window frame). This is especially true for small-sized vacuum glass products, where the presence of the vent and getter is even more unsightly.

[0007] and Figure 1c Although the vacuum glass structure eliminates the need for exhaust pipes and sealing plates, the two panes of glass must still be heated in a vacuum furnace during the edge sealing process. Exhaust must be vented through the edge seams before the seams are sealed to create the vacuum glass. The unpredictable nature of this venting process can lead to instability in the product's vacuum level and yield. Furthermore, the process and equipment design are complex and costly, and it's difficult to prevent getter dots from protruding from the window frame, affecting the overall appearance of the window. Utility Model Content

[0008] This invention provides a glass splicing component and vacuum glass to solve the technical problem that the appearance of existing vacuum glass is poor due to the presence of exhaust vents and getters.

When the splicing glass piece and the glass body of the first glass are re-spliced ​​to form a complete first glass, the splicing glass piece is used.

[0016] This utility model discloses a vacuum glass, which includes a first glass and a second glass, the second glass being disposed opposite to the first glass; the first glass includes a glass body and a glass splicing component as described in any of the above claims; when the glass splicing component is spliced ​​with the glass body and the first glass and the second glass are disposed opposite to each other, a whole piece of vacuum glass is formed.

[0017] Furthermore, multiple supports are provided between the first glass and the second glass; the edges of the first glass and the second glass are sealed with solder.

[0021] 2. The glass splicing components of this utility model can be manufactured separately and are suitable for the production of vacuum glass of various sizes, thicknesses and processes. They are also convenient for combining energy-saving glass such as photovoltaic glass and dimming glass into various multifunctional vacuum glass. Obviously, this can reduce the design and manufacturing difficulty of the main production line, improve production efficiency and yield, reduce production costs, ensure product quality, and promote the mass production of vacuum glass.

[0022] 3. The glass splicing component of the present invention is located at one corner of the glass body and is very small in size. It is not exposed after being embedded in the window frame, making the whole window more beautiful.

[0044] like Figures 2 to 4 As shown, this utility model discloses a glass splicing component 1, which is a cut-off portion of the first glass 2 of vacuum glass. The portion of the first glass 2 cut off by the glass splicing component 1 forms the glass body 21 of the first glass 2. The glass splicing component 1 includes a splicing glass piece 11, a vacuum glass tube 12, a getter 13, and a sealing sheet 14. One side of the splicing glass piece 11 has a groove 111, and the bottom of the groove 111 has a through hole 112. Optionally, the groove 111 is a circular groove. The other side of the splicing glass piece 11 has a storage groove 113. The vacuum glass tube 12 passes through the through hole 112 of the splicing glass piece 11, with one end of the vacuum glass tube 12 located in the groove 111, and the other end of the vacuum glass tube 12 passing through the through hole 112 of the splicing glass piece 11 to the storage groove 113 on the other side of the splicing glass piece 11. The other end of the vacuum glass tube 12 is connected to the splicing glass piece 11 by solder. The spliced ​​glass component 11 can be re-spliced ​​with the glass body 21 to form a complete first glass 2. The bottom of the storage compartment 113 has an assembly groove 114, within which the getter 13 is disposed. A sealing plate 14 is disposed at the opening of the assembly groove 114, sealing the getter 13 within the assembly groove 114. Optionally, the sealing plate 14 is disposed at the opening of the assembly groove 114 using solder.

[0045] Optionally, such as Figure 5 , Figure 6 As shown, a chamfer 5 is provided on the inclined surface of the splicing glass component 11.

[0046] An exemplary processing procedure for a glass splicing component 1:

[0047] like Figures 2 to 6As shown, firstly, a spliced ​​glass component 11 is custom-made at a glass processing manufacturer or workshop. One side of the spliced ​​glass component 11 has a groove 111, and the bottom of the groove 111 has a through hole 112. The other side of the spliced ​​glass component 11 has an L-shaped first step 115. The space formed by the first step 115 and the spliced ​​glass component 11 can be regarded as a storage groove 113. The bottom of the storage groove 113 has an assembly groove 114, and the opening of the assembly groove 114 has a second step 116. Then, the getter 13 is placed into the assembly groove 114, and a pre-prepared sealing piece 14 with solder around its perimeter is embedded into the second step 116. The sealing piece 14 seals the getter 13 located in the assembly groove 114. If the getter 13 needs to be activated, the spliced ​​glass component 11 and the sealing piece 14 are placed in a vacuum heating furnace, heated to the activation temperature, and kept at that temperature for a period of time according to the process requirements of the getter 13. Then, the temperature is increased further until the melting temperature of the solder is reached, and then the component is cooled and removed from the furnace for later use. If the getter 13 does not require activation, a low-temperature solder and corresponding welding method can be selected to weld the sealing plate 14 onto the second step 116, or the getter 13 can be fixed in the assembly groove 114 by other methods, without the need for welding the sealing plate 14 for sealing. The extraction glass tube 12 can be directly fabricated on the splicing glass component 11 in a professional factory to form the glass splicing component 1. Alternatively, after designing the length, diameter, and glass material of the extraction glass tube 12, it can be custom-made and then fused and sealed in the assembly groove 114 with the selected glass solder, or fused and sealed at the connection between the extraction glass tube 12 and the bottom of the storage groove 113. This process can be completed in the same heating and cooling process as the above-mentioned activation process of the getter 13, or it can be carried out separately. Manufacturers can choose according to their material and process technology requirements.

[0048] like Figure 7 , Figure 8As shown, this utility model also discloses a vacuum glass, which includes a first glass 2 and a second glass 3. The first glass 2 includes a glass body 21 and a glass splicing component 1 as described in any of the preceding claims. The glass body 21 of the first glass 2 and the second glass 3 are arranged opposite each other, with a gap between them. A plurality of supports 4 are also provided in the gap between the glass body 21 and the second glass 3, and the plurality of supports 4 are evenly distributed in an array. The edges of the glass body 21 and the second glass 3 are sealed with solder, and the notch of the glass body 21 and the corresponding position of the second glass 3 are not treated, thus forming the glass body to be assembled for the vacuum glass. The glass splicing component 1 is set at the notch of the glass body 21, and the glass splicing component 1 is spliced ​​with the glass body 21, and the two are connected to form a complete first glass 2 by glass solder or metal solder. The edges of the glass splicing component 1 and the second glass 3 are sealed with glass solder or metal solder, so that the gap between the first glass 2 and the second glass 3 forms a sealed space. This sealed space can be connected to the outside through a vacuum glass tube 12. The sealed space is evacuated and vented using a vacuum tube 12. Once the required level of sealing is achieved, one end of the vacuum tube 12 located within the groove is sealed using methods such as infrared radiation, laser, or electric heating, thus forming a vacuum glass panel. Finally, a selected laser is used to drill a hole in the sealing plate 14 through the second glass 3 and release the seal, allowing the getter 13 located within the groove 111 to draw in air through the small hole, ensuring a long service life for the vacuum glass. This completes the vacuum glass manufacturing process. Various vacuum venting equipment and methods are available, and manufacturers can choose the appropriate method.

[0049] Optionally, the end of the vacuum glass tube 12 located in the storage groove 113 can be melted and sealed to increase the thickness of the vacuum glass tube 12 and further improve the sealing performance of the vacuum glass.

[0050] Optionally, such as Figure 8 As shown, the area of ​​the first glass 2 is smaller than that of the second glass 3. This will form a step at the edge of the vacuum glass, and the solder is located on the step, thus forming a "staggered edge sealing" vacuum glass.

[0051] Optionally, such as Figure 9 As shown, the area of ​​the first glass 2 is equal to the area of ​​the second glass 3. The edges of the vacuum glass are aligned, and the solder is located between the first glass 2 and the second glass 3, thus forming a "flat-sealed" vacuum glass.

[0052] An exemplary processing procedure for vacuum glass:

[0053] like Figures 2 to 9As shown, a corner of the first glass 2 is cut off to obtain a glass body 21 with a notch. The cut-off scrap is returned to the factory for processing to replace it, resulting in a spliced ​​glass component 11, which is an isosceles right triangle. A chamfer 5 is also provided on the inclined surface of the spliced ​​glass component 11. A groove 111 is provided on one side of the spliced ​​glass component 11, and a through hole 112 is opened at the bottom of the groove 111. A storage slot 113 is provided on the other side of the spliced ​​glass component 11. Then, a suction glass tube 12 is inserted through the through hole 112 of the spliced ​​glass component 11. One end of the suction glass tube 12 is located in the groove 111, and the other end is located in the storage slot 113. An assembly slot 114 is provided at the bottom of the storage slot 113 for placing a getter 13. Of course, the geometric shape of the spliced ​​glass component 11 can be an isosceles right triangle, or it can be a quadrilateral, a circle, a rectangle, or other geometric shapes. The isosceles right triangle in this embodiment is the optimal implementation method. When both the getter 13 and the suction glass tube 12 are disposed on the spliced ​​glass component 11, a glass splicing component 1 is obtained.

[0054] In this embodiment, the isosceles right-angled triangular spliced ​​glass component 11 has a leg length of 32mm, which is suitable for the fabrication of vacuum glass of various sizes. The assembly groove 114 can be a circular blind hole or any other suitable groove shape. The thickness of the first glass 2 is 5mm, and the size of the getter 13 is φ6×2mm. Therefore, the diameter of the assembly groove 114 is 7mm, and the groove depth is 3mm. The diameter of the recess 111 is 7mm, and the groove depth is 2.5mm. The diameter of the through hole 112 is 2.4mm, and the outer diameter of the vacuum glass tube 12 is 2.4mm, and the inner diameter is 1.5mm. The width of the first step 115 is 5mm, and the height of the first step 115 is 1mm. The width of the second step 116 is 1mm, and the height of the second step 116 is 1mm.

[0055] The splicing glass component 11 can be manufactured using various methods, such as molding by heating and softening glass or 3D printing. The splicing glass component 11 and the vacuum glass tube 12 can be formed simultaneously, or the vacuum glass tube 12 can be welded to the splicing glass component 11 using glass solder. The material of the vacuum glass tube 12 can be soda-lime glass or a special glass with infrared absorption properties, chosen by the manufacturer depending on the heating and sealing method. The sealing sheet 14 located at the second step 116 is made of metal or alloy foil with a thickness of 0.5 mm. For example, it can be made of Kovar alloy foil with a coefficient of expansion similar to soda-lime glass, and glass solder is placed around the sealing sheet 14. When the getter 13 is activated by heating in a vacuum, the glass solder on the sealing sheet 14 melts and seals the groove 111. The sealing sheet 14 with glass solder can be customized from specialized manufacturers.

[0056] The glass body 21 and the second glass 3 are positioned opposite each other, and multiple supports 4 are provided in the gap between the glass body 21 and the second glass 3. The edges of the glass body 21 and the second glass 3 are sealed with glass solder, and the notches in the glass body 21 and the corresponding positions in the second glass 3 are left untreated, thus forming the glass assembly body of the vacuum glass. Appropriate amounts of glass solder are evenly distributed on the beveled surface, chamfer 5, and one side of the first step 115 of the glass splicing component 1. The glass solder on one side of the first step 115 is used to weld and seal the glass splicing component 1 to the glass assembly body, and the glass solder on the beveled surface and chamfer 5 is used to weld and seal the glass splicing component 1 to the glass body 21. In this way, the glass splicing component 1 is reassembled back into the original position of the first glass 2, thus forming a complete piece of vacuum glass. The sealed space inside the vacuum glass is connected to the vacuum glass tube 12 through a storage slot 113.

[0057] The glass splicing component 1 and the glass assembly body are placed together in the edge-sealing heating furnace. As the heating temperature rises, the glass solder attached to it will melt, and this melting process is the edge-sealing process described above. After the edge-sealing is completed, the vacuum glass can enter the vacuum furnace for vacuum degassing. After reaching the required vacuum level, the end of the vacuum extraction glass tube 12 located in the groove 111 is melted and sealed using methods such as infrared, laser, and electric heating. After cooling, it is taken out of the furnace. Then, as mentioned before, the getter 13 sealed in the assembly groove 114 is unsealed using laser, thus completing the entire process of vacuum glass production.

[0058] If a continuous furnace is used for production, the aforementioned edge-sealing heating furnace and vacuum furnace can be connected and operated. After vacuum sealing, the glass does not need to be cooled before entering the vacuum furnace. Vacuuming and sealing are performed under heat preservation conditions, which saves energy and improves production efficiency. If an integrated edge-sealing and exhaust furnace or a continuous furnace with the same process and equipment is used for production, it is advisable to thicken and lengthen the exhaust glass tube 12 and strengthen the welding strength between the exhaust glass tube 12 and the spliced ​​glass parts 11. This facilitates the connection of exhaust devices such as water-cooled exhaust heads for vacuum exhaust and sealing.

[0059] For details regarding the selection of getter 13, material selection, and processing techniques used in vacuum glass, please refer to the Chinese invention patent document with authorization announcement number CN114671630B. This utility model will not repeat these details. In this utility model, the first glass 2 of the vacuum glass is partially cut, selectively separated, and then spliced ​​together, which improves the production efficiency and yield of vacuum glass. At the same time, it achieves structural reform and quality improvement of vacuum glass, especially in ensuring the effective use of vacuum glass and the absence of foreign matter on its surface, representing a substantial improvement.
