[0002] Vacuum glass, as a new generation of energy-saving glass, has been widely used in various industries such as construction and medicine due to its excellent heat insulation and sound insulation properties. However, existing vacuum glass systems have components such as suction pipes, protective caps (sealing plates), and getters, which cause the surface appearance of the vacuum glass to be affected by the presence of exhaust vents and getters, resulting in an unsightly appearance.

[0003] The applicant previously filed a Chinese utility model patent application with application number 2025202366622, which disclosed a glass splicing component. This component features a groove on one side of a spliced ​​glass piece, with a through hole within the groove. The other end of a vacuum extraction glass tube passes through the through hole to the other side of the spliced ​​glass piece, and is connected to the spliced ​​glass piece. When the spliced ​​glass piece is re-spliced ​​with the main body of a first glass piece, a complete first glass piece is formed. This vacuum glass structure, due to the use of a fragile vacuum extraction glass tube, is suitable for the process and equipment of venting and sealing in vacuum furnaces, but not for use in low-cost integrated edge sealing and venting furnaces. Utility Model Content

[0004] This invention provides a glass splicing component and vacuum glass to solve the technical problem that vacuum glass structures are unsuitable for use in low-cost integrated edge sealing, exhaust, and sealing heating furnaces due to the use of easily broken vacuum glass tubes.

The splicing member includes a first side and a second side, and has a through hole penetrating the first and second sides. The shape of the splicing member is the same as the shape of a truncated corner portion of the first glass of the vacuum glass. One end of the metal tube is located on the second side of the splicing member and is connected to the splicing member. The other end of the metal tube passes through the through hole and groove to the first side. The other end of the metal tube is higher than the first side. The splicing member can be re-spliced ​​with the glass body of the first glass to form a complete first glass.

[0010] Furthermore, one end of the metal tube is trumpet-shaped and located inside the storage slot.

[0011] Furthermore, the glass splicing component also includes a transition piece, which is disposed in the through hole and the edge of the transition piece contacts the first side surface; one end of the transition piece has a receiving groove, and the bottom of the receiving groove has an assembly hole for a metal tube to pass through; the transition piece is made of Kovar alloy.

[0012] Furthermore, the other end of the transition piece has an assembly groove, which is arranged in a ring around the assembly hole; the assembly groove contains a getter, and a sealing piece is set at the opening of the assembly groove to seal the getter inside the assembly groove.

[0013] This utility model discloses a vacuum glass, which includes a first glass and a second glass, with the second glass 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 embodiments; 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.

[0014] 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.

[0044] First Embodiment

[0045] This embodiment discloses a glass splicing component 1, such as... Figures 1 to 4As shown, the glass splicing component 1 includes a splicing piece 11, a metal tube 61, a getter 13, and a sealing plate 14. The first glass 2 of the vacuum glass, with a corner cut off, forms the glass body 21 of the first glass 2. The shape of the cut-off corner is the same as the shape of the splicing piece 11, i.e., the splicing piece 11 is truncated. One side of the splicing piece 11 is a first side 117, and the other side is a second side 118. The first side of the splicing piece 11 has a groove 111, and the bottom of the groove 111 has a through hole 112. Optionally, the groove 111 is hemispherical. The second side of the splicing piece 11 has a storage groove 113. One end of the metal tube 61 is located in the storage groove 113, and the other end of the metal tube 61 passes through the through hole 112 and the groove 111 to the first side of the splicing piece 11. The other end of the metal tube 61 is higher than the first side. The metal tube 61 is connected to the splicing piece 11 by solder. The splicing 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.

[0046] Optionally, such as Figure 2 , Figure 3 As shown, a chamfer 5 is provided on the beveled surface of the spliced ​​glass component.

[0047] Optionally, the splicing component 11 is made of Kovar alloy material, and the metal tube 61 is made of oxygen-free copper tube. The oxygen-free copper tube is connected to the splicing component 11 by silver-copper solder. Optionally, the Kovar alloy material can be of type 4J29 or 4J36. The splicing component 11 is made of 5mm thick Kovar alloy material, which has a coefficient of thermal expansion similar to that of glass. This allows for various connection methods between the splicing component 11 and soda-lime glass, such as glass brazing or laser welding, which can be selected based on the sealing temperature and equipment process. Using the metal tube 61 instead of the original glass tube makes the metal tube less prone to breakage, thus ensuring the yield of the glass splicing component 1.

[0048] Optionally, the length of the metal tube 61 ranges from 4mm to 100mm. Optionally, the length of the metal tube 61 is 4mm or approximately 4mm. Optionally, the length of the metal tube 61 is 100mm or approximately 100mm. Of course, the length of the metal tube 61 can also be manufactured according to the requirements of the vacuum exhaust system.

[0049] Optionally, the outer diameter of the metal tube 61 is 3mm, the wall thickness is 0.5mm, and the inner diameter is 2mm. Alternatively, the outer diameter of the metal tube 61 is 3mm, the wall thickness is 0.3mm, and the inner diameter is 2.4mm. Of course, the wall thickness and inner and outer diameters of the metal tube 61 can be selected according to the vacuum hose of the vacuum exhaust system.

[0050] Optionally, the vacuum hose can be a high-temperature silicone rubber vacuum hose, a fluororubber sealed hose, a stainless steel corrugated hose, or a stainless steel multilayer vacuum hose, etc., which can be further selected according to the operating temperature and equipment requirements.

[0051] Optionally, such as Figure 4 As shown, one end of the metal tube 61 is flared, and the outer wall of the other end of the metal tube 61 is polished to reduce the coefficient of friction and facilitate the insertion of the vacuum hose of the vacuum exhaust system. When the metal tube 61 is assembled with the splice 11, the other end of the metal tube 61 passes through the through hole 112 and the groove 111 to the first side of the splice 11, and the flared end of the metal tube 61 is located in the storage groove 113. This prevents the entire metal tube 61 from passing through the through hole 112 and also serves as a limit. At the same time, there is a sandwich between the flared end of the metal tube 61 and the bottom of the storage groove 113. By placing solder in the sandwich, the positioning welding of the metal tube 61 and the splice 11 is achieved.

[0052] Optionally, such as Figure 5 , Figure 6As shown, the splicing component 11 has a through hole 112 penetrating the first side and the second side. The splicing component 11 also has a connecting groove 7, which is located on the second side 118 and connects to the through hole 112. During vacuum glass evacuation, the sealed space between the first glass 2 and the second glass 3 is connected to the through hole 112 through the connecting groove 7, facilitating vacuum evacuation. The glass splicing component 1 disclosed in this embodiment also includes a transition component 62 made of Kovar alloy. The splicing component 11 is made of glass material, and the metal tube 61 is made of oxygen-free copper tube. The metal tube 61 is connected to the splicing component 11 through the transition component 62. The transition component 62 is processed from Kovar alloy plate using a stamping process. The transition component 62 is cylindrical, and one end of the transition component 62 has a receiving groove 63. The bottom of the receiving groove 63 has an assembly hole 64, through which the metal tube 61 can pass. The transition piece 62 also has an edge 65, which surrounds the outer surface of the transition piece 62 and is located at the opening of the receiving groove 63. The transition piece 62 is placed in the through hole 112 of the splicing piece 11, with the edge 65 of the transition piece 62 abutting against the first side surface. When the splicing piece 11 is made of glass, the transition piece 62 is connected to the splicing piece 11 by glass solder. When the splicing piece 11 is made of Kovar alloy, the transition piece 62 is connected to the splicing piece 11 by silver-copper solder. After the transition piece 62 and the splicing piece 11 are assembled, one end of the metal tube 61 is located in the storage groove 113, and the other end of the metal tube 61 passes through the assembly hole 64 and the receiving groove 63 to the first side surface of the splicing piece 11, so that the other end of the metal tube 61 is higher than the first side surface. Optionally, the connection method between the metal tube 61 and the transition piece 62 also includes laser welding, electron beam welding, etc. The transition piece 62, made of Kovar alloy, allows the metal tube 61 with a significantly different coefficient of thermal expansion to be connected to the glass, thus preventing the glass splice piece 11 from breaking.

[0053] Optionally, such as Figure 7 , Figure 8 As shown, based on the above optional technical solutions, a further improvement is made: the other end of the transition piece 62 has an assembly groove 114, which surrounds the assembly hole 64 in a ring, i.e., the assembly groove 114 is an annular groove. Both the getter 13 and the sealing piece 14 are annular. The getter 13 is disposed within the assembly groove 114. The sealing piece 14 is disposed at the opening of the assembly groove 114, sealing the getter 13 within the assembly groove 114. Optionally, the sealing piece 14 is disposed at the opening of the assembly groove 114 using solder.

[0054] This optional technical solution has the following advantages:

[0055] 1. When the splicing components are made of glass, there is no need to open the assembly groove on the splicing components; only holes need to be drilled in the splicing components, which facilitates the processing of the splicing components.

[0056] 2. By using a large-diameter, annular getter, the volume of air that the getter can absorb increases from 58 cubic millimeters to 132 cubic millimeters while keeping the getter thickness constant. Under the same materials and activation conditions, the air absorption capacity more than doubles, which is beneficial to improving the lifespan of vacuum glass.

[0057] 3. This structure simplifies the processing of glass splicing components and transition pieces, reducing manufacturing costs. The encapsulation and activation of the getter, as well as the connection between the metal tube and the transition piece, can all be completed within a single heating and cooling process. This also further simplifies the vacuum glass manufacturing process.

[0058] Optionally, such as Figure 8 As shown, based on the above-mentioned optional technical solutions, a further improvement is made: one end of the metal tube 61 is provided with an edge 65, which surrounds the outer surface of the metal tube 61. The end of the metal tube 61 with the edge 65 is disposed in the receiving groove 63, and the metal tube 61 communicates with the assembly hole 64. Optionally, the metal tube 61 is connected to the transition piece 62 by solder.

[0059] An exemplary manufacturing process for a glass splicing component 1:

[0060] like Figures 1 to 4 , Figure 9As shown, firstly, a glass assembly is custom-made at a glass processing manufacturer or workshop. A corner of the first glass 2 is cut off to obtain a glass body 21 with a notch, and the cut-off waste is returned to the factory for recycling. A truncated splice 11 is prepared using Kovar alloy material, and the truncated splice 11 is reassembled with the glass body 21 to form the first glass 2. One side of the splice 11 has a groove 111, and the bottom of the groove 111 has a through hole 112. The other side of the splice 11 has an L-shaped first step 115, and the space formed by the first step 115 and the splice 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 in the second step 116. The sealing piece 14 seals the getter 13 located in the assembly groove 114. One end of the metal tube 61, which is flared, is located in the storage groove 113. The other end of the metal tube 61 passes through the through hole 112 and the groove 111 to the first side of the splicing component 11. Silver-copper solder is placed between the metal tube 61 and the splicing component 11. The splicing component 11, which is equipped with getter 13, and the metal tube 61 are placed together in a low vacuum furnace with a pressure of less than 1 Pa. The furnace is heated to 500°C for five minutes, and then the temperature is raised to between 730°C and 820°C and held for one minute. After natural cooling, the splicing component 1 is removed from the furnace. In one heating and cooling process, the sealing of the getter 13 by the sealing plate 14, the activation of the getter 13, and the connection between the metal tube 61 and the splicing component 11 are completed simultaneously, finally obtaining the glass splicing component 1.

[0061] Second Embodiment

[0062] like Figures 10 to 12As 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 any optional glass splicing component 1 in the first embodiment. The glass body 21 of the first glass 2 and the second glass 3 are arranged opposite each other, and there is 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 by 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 in 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, metal solder or laser welding technology. The edges of the glass splicing component 1 and the second glass 3 are sealed by glass solder or metal solder, so that the gap between the first glass 2 and the second glass 3 forms a sealed space. The sealed space is connected to the outside world through a metal tube 61. The sealed space is evacuated and vented through the metal tube 61. After the required level of sealing is achieved, the metal tube 61 is sealed again. This can be done by mechanically clamping the metal tube 61, heating and sealing it, or clamping it first and then sealing it. 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 in the groove 111 to draw in air through the small hole, ensuring a good lifespan for the vacuum glass. This completes the vacuum glass manufacturing process. Various vacuum venting equipment and methods, as well as methods for sealing the metal tube 61, can be used, and manufacturers can choose the appropriate method.

[0063] Optionally, after the end of the metal tube 61 that is higher than the first side is sealed, this end of the metal tube 61 is lower than the first side and is located in the groove 111 of the splice 11 or the receiving groove 63 of the transition member 62. This increases the thickness at the location of the metal tube 61, further improving the sealing performance of the vacuum glass.

[0064] Optionally, such as Figure 11 As shown, the area of ​​the first glass 2 is smaller than the area of ​​the second glass 3. The edge 65 of such vacuum glass will form a step, and the solder is located on the step, thus forming a "staggered edge sealing" vacuum glass.

[0065] Optionally, such as Figure 12 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 at 65°, and the solder is located between the first glass 2 and the second glass 3, thus forming a "flat-sealed" vacuum glass.

[0066] An exemplary processing procedure for vacuum glass:

[0067] like Figures 1 to 12 As shown, a corner of the first glass 2 is cut off to obtain a glass body 21 with a notch, and the cut-off waste is returned to the factory for recycling. The splicing component 11 is an isosceles right triangle. A chamfer 5 is also provided on the inclined surface of the splicing component 11. Of course, the geometric shape of the splicing component 11 can be an isosceles right triangle, or it can be a quadrilateral, a circle, a rectangle, or other geometric shapes, but the isosceles right triangle in this embodiment is the optimal implementation. When the getter 13 and the metal tube 61 are both provided on the splicing component 11, a glass splicing component 1 is obtained. The glass body 21 is arranged opposite to the second glass 3, 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 by glass 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 vacuum glass. A suitable amount of glass solder is evenly distributed on the bevel, 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 body to be assembled, while the glass solder on the bevel and chamfer 5 is used to weld and seal the glass splicing component 1 to the glass body 21. This allows the glass splicing component 1 to be reassembled at the gap in the first glass 2, thus forming a complete piece of vacuum glass. The sealed space inside the vacuum glass is connected to the metal tube 61 through the storage slot 113. The glass splicing component 1 and the glass body to be assembled are placed together in the edge-sealing heating furnace. As the heating temperature rises, the glass solder will melt; this melting process is the edge-sealing process described above. During the cooling process, the vacuum glass is evacuated using a vacuum exhaust system's vacuum hose. After reaching the required vacuum level, the metal tube 61 is clamped before being melted and sealed. Then, as mentioned earlier, the getter 13 encapsulated in the assembly tank 114 is unsealed using a laser, and then the glass is removed from the furnace, thus completing the entire process of edge sealing, venting, and sealing in vacuum glass production. This process involves processing the vacuum glass using a low-cost integrated edge sealing, venting, and sealing furnace.

[0068] 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 reassembled, improving the production efficiency and yield of vacuum glass. Simultaneously, it achieves structural reform and quality improvement of the vacuum glass, facilitating vacuuming. In particular, it represents a substantial improvement in ensuring the effective use of the vacuum glass and maintaining a surface free of foreign matter.
