Description

Technical Field

[0001] This invention relates to the field of vacuum glass processing technology, and more specifically to a sealing device for vacuum glass processing. Background Technology

[0002] Generally speaking, the edge sealing device for vacuum glass processing is a special equipment used for sealing the edges of double-layer vacuum glass. In the process of vacuum glass edge sealing, the edge sealing furnace is used to heat and melt the low melting point glass filler material pre-placed on the edge of the double-layer glass for edge sealing. During the hot melt edge sealing operation, the glass needs to be continuously pressurized to ensure that the molten filler material fully fills the glass gap and ensures the sealing effect. In actual batch edge sealing operations, multiple pieces of vacuum glass are often stacked in layers on the furnace support for simultaneous processing. The layered stacking structure cannot guarantee that the pressure on each layer of vacuum glass is uniform, which can easily lead to insufficient pressure on the upper layer and overload on the lower layer, causing problems such as air leakage during edge sealing and glass breakage under pressure. At the same time, after the hot melt edge sealing is completed, it is necessary to wait for the furnace temperature to drop to 60 degrees Celsius before the finished glass can be taken out. A large amount of high-temperature residual heat is left in the furnace, which can be directly used for preheating the next batch of glass. However, the existing integrated furnace support structure will form a rigid obstruction for glass loading and unloading. The stacked vacuum glass cannot be taken out quickly and individually. The method of removing the entire bracket for material removal will cause the furnace door to be left open for a long time, resulting in rapid leakage of residual heat from the furnace. The utilization rate of residual heat is extremely low, which greatly increases the energy consumption cost of repeated heating of the edge sealing furnace. The overall processing convenience and energy saving are poor. Based on this, the present invention aims to provide an edge sealing device for vacuum glass processing that can realize independent pressure stabilization and pressurization of a single piece of glass, convenient loading and unloading without the obstruction of the support, and reduce the loss of residual heat in the furnace. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a sealing device for vacuum glass processing, thereby solving the technical problems in the prior art.

[0004] The objective of this invention can be achieved through the following technical solutions: A sealing device for vacuum glass processing, comprising: A slide rail is fixedly installed on the bottom plate of the sealing furnace. A drive source is fixedly installed at the top of the sealing furnace, and the movable end of the drive source extends into the sealing furnace. A support frame is slidably installed on the slide rail. Multiple U-shaped frames are fixedly installed on the support frame from bottom to top. Each U-shaped frame has a U-shaped frame fixedly installed at its top. Lifting grooves and horizontal grooves are opened on the inner walls of both sides of the U-shaped frame. The horizontal grooves are connected to the lifting grooves. A carrying plate is provided between the U-shaped frame and the pressure plate. A second protrusion is fixedly installed on both sides of each carrying plate. The second protrusion is slidably installed in the lifting groove. A sliding groove is opened on both sides of each carrying plate. Graphite paper is placed on the carrying plate, and vacuum glass is placed on the graphite paper. The lifting frame has multiple first protrusions fixedly installed on its inner side, each first protrusion corresponding to a sliding groove. The first protrusions are slidably installed in the sliding groove. A U-shaped block is fixedly installed on the top of the lifting frame, and a connecting component is provided on the U-shaped block. When the support frame is located inside the sealing furnace, the U-shaped block is fixedly connected to the movable end of the drive source through the connecting component. The drive source drives the lifting frame to rise and fall, and the lifting frame drives the carrying plate to rise and fall. When the carrying plate rises, the vacuum glass abuts against the bottom of the pressure plate. When the carrying plate rises, the second protrusion is aligned with the horizontal groove, and the second protrusion is slidably connected with the horizontal groove, and the lifting groove is slidably connected with the sliding groove.

[0005] As a further aspect of the present invention: each of the carrier plates has a handle groove at its bottom, and the handle groove is located near the opening of the sealing furnace.

[0006] As a further aspect of the present invention: the connecting assembly includes a connecting rod and a bolt, the connecting rod is fixedly installed on the movable end of the drive source, the end of the U-shaped block facing the connecting rod is an open end, and the U-shaped block is provided with a bolt that passes through the connecting rod, the bolt being a detachable design.

[0007] As a further aspect of the present invention: a through groove is provided on the carrier plate. When the graphite paper and vacuum glass are placed on the carrier plate, the graphite paper covers the through groove. A lifting plate is slidably installed in the through groove. Each U-shaped frame is provided with a linkage component. The linkage component is used to drive the lifting plate to rise and fall. When the lifting plate rises, the lifting plate pushes the graphite paper and vacuum glass away from the carrier plate.

[0008] As a further aspect of the present invention: the linkage component includes a limiting block, and a limiting block is fixedly installed on each of the four inner walls of the through groove. The limiting block abuts against the bottom of the lifting plate. When the lifting plate abuts against the limiting block, the top of the lifting plate is flush with the top of the carrying plate.

[0009] As a further aspect of the present invention: the linkage component further includes a top column, which is fixedly installed on the U-shaped frame. When the load plate descends, the top column abuts against the bottom of the lifting plate, causing the lifting plate to slide and rise in the through groove. When the load plate rises and the second protrusion aligns with the horizontal groove, both the load plate and the lifting plate are located above the top column.

[0010] As a further aspect of the present invention: the top of the lifting plate is provided with a plurality of equally spaced grooves.

[0011] As a further aspect of the present invention: a plurality of equally spaced fixing plates are fixedly installed in the through groove, each fixing plate being slidably connected to the groove, and the top of the fixing plate being flush with the top of the carrying plate.

[0012] The beneficial effects of this invention are: 1. In this invention, the lifting frame is driven to rise and fall vertically by a drive source. The lifting frame drives each set of load plates to rise and fall independently with the help of the first protrusion. Together with the corresponding pressure plates above, they form an independent pressure station. The lifting groove restricts the lateral movement of the load plates throughout the process, ensuring that the pressure value of each piece of vacuum glass is completely consistent. This avoids the problems of uneven pressure on multiple layers of glass, insufficient pressure on the upper layer leading to air leakage during edge sealing, and overload of the lower layer causing glass breakage in traditional stacked brackets, thus improving the yield of batch edge sealing products. 2. In this invention, the lifting groove and the horizontal groove connected on the U-shaped frame form an L-shaped sliding track. After the glass is cooled to 60 degrees Celsius, the carrying plate can slide into the horizontal groove through the second protrusion to achieve separate horizontal pulling. There is no need to move the entire support frame out of the sealing furnace along the slide rail. At the same time, after the carrying plate slides horizontally, it is completely misaligned with the pressure plate without obstruction. Workpieces can be directly picked up and put in from the top, shortening the furnace door opening time, reducing the loss of residual heat in the furnace, and maximizing the use of residual heat in the furnace for preheating the next batch of workpieces. This avoids the problem of material picking being obstructed by the traditional integrated bracket and having to be moved out of the bracket as a whole, resulting in a large waste of residual heat. 3. In this invention, during the descent of the carrier plate, the top column abuts against the lifting plate, causing the lifting plate to slide upward along the through groove and lift the graphite paper and vacuum glass, creating a ventilation gap between the bottom of the glass and the carrier plate. This, combined with the groove on the top of the lifting plate, forms a through heat dissipation channel, accelerating the airflow rate at the bottom of the glass and quickly removing the heat accumulated at the bottom of the workpiece. This avoids the problems of slow heat dissipation and excessively long cooling cycles caused by the bottom of the vacuum glass being placed in close contact. At the same time, the entire heat dissipation structure relies on mechanical linkage and does not require external electrical drive components, making it suitable for the high-temperature working environment of the edge sealing furnace and improving the stability of equipment operation.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-10 As shown, the present invention is a sealing device for vacuum glass processing, comprising: A slide rail 2 is fixedly installed on the bottom plate of the sealing furnace. A drive source is fixedly installed at the top of the sealing furnace, and the movable end of the drive source extends into the sealing furnace. A support frame 1 is slidably installed on the slide rail 2. Multiple U-shaped frames 7 are fixedly installed on the support frame 1 from bottom to top. Each U-shaped frame 7 has a U-shaped frame 7 fixedly installed at its top. Lifting grooves 701 and horizontal grooves 702 are opened on the inner walls of both sides of the U-shaped frame 7. The horizontal grooves 702 are connected to the lifting grooves 701. A carrying plate 9 is provided between the U-shaped frame 7 and the pressure plate 8. A second protrusion 902 is fixedly installed on both sides of each carrying plate 9. The second protrusion 902 is slidably installed in the lifting groove 701. A sliding groove 901 is opened on both sides of each carrying plate 9. Graphite paper 10 is placed on the carrying plate 9. Vacuum glass 11 is placed on the graphite paper 10. The lifting frame 3 has multiple first protrusions 301 fixedly installed on its inner side. Each first protrusion 301 corresponds to a sliding groove 901. The first protrusion 301 is slidably installed in the sliding groove 901. A U-shaped block 4 is fixedly installed on the top of the lifting frame 3. A connecting component is provided on the U-shaped block 4. When the support frame 1 is located in the sealing furnace, the U-shaped block 4 is fixedly connected to the movable end of the drive source through the connecting component. The drive source drives the lifting frame 3 to rise and fall. The lifting frame 3 drives the carrying plate 9 to rise and fall. When the carrying plate 9 rises, the vacuum glass 11 abuts against the bottom of the pressure plate 8. When the carrying plate 9 rises, the second protrusion 902 is aligned with the horizontal groove 702. The second protrusion 902 is slidably connected with the horizontal groove 702, and the lifting groove 701 is slidably connected with the sliding groove 901.

[0018] The support frame 1 is fixedly installed with multiple equally spaced support plates 101, and the pressure plate 8 is fixedly installed on the support plates 101.

[0019] In one embodiment, the sealing furnace of the vacuum glass sealing device is a dedicated high-temperature heating furnace, which integrates heating, precision temperature control, workpiece pressing, and vacuum extraction functions. It is adapted to the high-temperature welding and sealing process of vacuum glass. Before processing, the glass pretreatment is completed. Low-melting-point glass solder is evenly coated or pre-placed on the edges of the two glass plates to be joined. After the plates are assembled, a vacuum glass semi-finished product 11 to be sealed is formed. At the same time, graphite paper 10 is laid on the bottom of the vacuum glass 11. The graphite paper can receive the molten glass solder solution dripping during the high-temperature heating process, avoiding solder contamination of the carrier plate 9 and U-shaped frame 7 and other tooling structures. It can also ensure that the glass is heated evenly. The driving source can be a linear reciprocating motion component such as an electric cylinder or an electric telescopic rod, or other mechanisms that can realize vertical lifting and lowering motion such as a screw slide. This embodiment does not make specific limitations.

[0020] The working principle of this invention is as follows: First, the carrier plate 9, on which graphite paper 10 is laid and vacuum glass 11 is placed, is manually assembled into the U-shaped frame 7. Then, the support frame 1 is pushed to slide along the slide rail 2, sending all the carrier plates 9 and vacuum glass 11 into the processing area inside the edge sealing furnace. Then, the U-shaped block 4 is fixedly connected to the movable end of the furnace top drive source through the connecting component. The furnace door is closed and the built-in heating component of the edge sealing furnace is started, and the temperature inside the furnace rises to the working temperature, so that the low melting point glass brazing filler material pre-placed on the edge of the vacuum glass 11 is melted by the heat. Then, the furnace top drive source is started, and the drive source drives the U-shaped block 4 and the lifting frame 3 to move vertically upward as a whole. The first convex part on the inner side of the lifting frame 3... Block 301 slides against the sliding groove 901, simultaneously driving all the load plates 9 to move vertically upward along the lifting groove 701 of the U-shaped frame 7. During this stage, the lifting groove 701 horizontally limits the second protrusion 902, restricting the lateral displacement of the load plate 9 and ensuring that the load plate 9 only performs vertical lifting and lowering movements. This prevents the first protrusion 301 from abnormally shifting and getting stuck in the sliding groove 901. After the load plate 9 is lifted, the top surface of the upper vacuum glass 11 is tightly attached to the bottom surface of the pressure plate 8. The drive source outputs constant pressure to independently and evenly pressurize each group of vacuum glass 11, ensuring that the molten brazing filler fills the gap between the two layers of glass and avoiding the problem of edge leakage and sealing failure caused by uneven pressure. After the glass sealing and pressurization are completed, the furnace is kept in a sealed environment for natural cooling. After cooling, the drive source continues to drive the lifting frame 3 to lift slightly upwards until the second protrusions 902 on both sides of the carrying plate 9 slide to the top of the lifting groove 701 and are completely aligned with the horizontal groove 702. At this time, the vacuum glass 11 and the pressure plate 8 separate, releasing the pressurization state. Then, the furnace door is opened. When the furnace temperature drops to about 60 degrees Celsius, the carrying plate 9 is manually pulled horizontally. The second protrusions 902 slide horizontally along the horizontal groove 702, while the first protrusions 301 slide horizontally relative to each other along the sliding groove 901. The carrying plate 9 can then slide horizontally to the furnace door material removal position. In this configuration, there is no need to move the entire support frame 1 off the slide rail 2 and remove it from the sealing furnace. The vacuum glass 11 that has undergone sealing processing on the work plate 9 can be directly removed and replaced. After the work plate 9 is moved laterally, it can be completely misaligned and separated from the pressure plate 8 above. Without the pressure plate 8 obstructing the view, the operator can directly and conveniently take the graphite paper 10 and vacuum glass 11 from above, which effectively speeds up the workpiece replacement efficiency. At the same time, there is no need to remove the entire support frame, shortening the time the furnace door is open and avoiding the rapid loss of residual heat in the furnace caused by prolonged opening of the furnace door. This effectively improves the utilization rate of residual heat inside the sealing furnace and reduces the energy consumption of secondary heating in the furnace.

[0021] like Figure 8 As shown, in a preferred embodiment of the present invention, each of the carrier plates 9 is provided with a handle groove 903 at the bottom, and the handle groove 903 is close to the opening of the sealing furnace.

[0022] In practical application, when the loading plate 9 slides to the furnace door material handling position and requires manual horizontal pulling of the loading plate 9 to complete the loading and unloading operation, the operator can directly hook their fingers into the handle groove 903 at the bottom of the loading plate 9 and apply horizontal pulling force to smoothly drive the loading plate 9 to slide horizontally along the horizontal groove 702, simplifying the horizontal pulling operation of the loading plate 9 and improving the convenience and safety of loading and unloading operations.

[0023] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the connecting assembly includes a connecting rod 5 and a bolt 6. The connecting rod 5 is fixedly installed on the movable end of the drive source. The end of the U-shaped block 4 facing the connecting rod 5 is an open end. The U-shaped block 4 is provided with a bolt 6 that passes through the connecting rod 5. The bolt 6 is designed to be detachable.

[0024] In one embodiment, the connecting rod 5 has a socket for inserting a bolt 6.

[0025] In practical application, after the support frame 1 slides into the edge-sealing furnace processing station, the open end of the U-shaped block 4 wraps around the connecting rod 5 from the outside, so that the insertion hole of the connecting rod 5 is precisely aligned with the through hole on the side wall of the U-shaped block 4. Then, the bolt 6 is manually inserted vertically into the through hole and the insertion hole, and the bolt 6 is tightened to complete the rigid connection between the U-shaped block 4 and the connecting rod 5. When the equipment is running, the drive source drives the U-shaped block 4 and the lifting frame 3 to move vertically up and down synchronously through the connecting rod 5 and the bolt 6. When the equipment is under maintenance or the lifting structure needs to be disassembled, the bolt 6 can be pulled out directly to quickly separate the drive source and the lifting frame 3, and the two movements are independent of each other.

[0026] like Figures 1-9 As shown, in a preferred embodiment of the present invention, the carrier plate 9 is provided with a through groove 12. When the graphite paper 10 and the vacuum glass 11 are placed on the carrier plate 9, the graphite paper 10 covers the through groove 12. A lifting plate 13 is slidably installed in the through groove 12. Each of the U-shaped frames 7 is provided with a linkage component. The linkage component is used to drive the lifting plate 13 to rise and fall. When the lifting plate 13 rises, the lifting plate 13 pushes the graphite paper 10 and the vacuum glass 11 away from the carrier plate 9.

[0027] In practical application, after the vacuum glass 11 is pressurized and sealed, it enters the furnace cooling process. The linkage component starts and drives the lifting plate 13 to slide vertically upward along the inner wall of the through groove 12. The top of the lifting plate 13 lifts the center area of ​​the graphite paper 10, and simultaneously drives the center position of the vacuum glass 11 above to rise slightly, so that the graphite paper 10, the vacuum glass 11 as a whole and the surface of the carrier plate 9 are separated. After the cooling process is completed, the linkage component drives the lifting plate 13 to reset. The lifting plate 13 falls back into the through groove 12, and the graphite paper 10 and the vacuum glass 11 are re-attached to the surface of the carrier plate 9. This avoids the problems of the traditional structure where the bottom of the vacuum glass 11 is completely attached to the carrier plate 9, there is no heat dissipation gap at the bottom of the glass, the heat cannot be dissipated quickly, the natural cooling speed in the furnace is slow, and the single batch processing cycle is long.

[0028] like Figures 3-10 As shown, in a preferred embodiment of the present invention, the linkage component includes a limiting block 14. A limiting block 14 is fixedly installed on each of the four inner walls of the through groove 12. The limiting block 14 abuts against the bottom of the lifting plate 13. When the lifting plate 13 abuts against the limiting block 14, the top of the lifting plate 13 is flush with the top of the carrying plate 9.

[0029] In practical application, when the carrier plate 9 rises vertically for glass pressure sealing, the carrier plate 9 simultaneously drives the internal limiting block 14 of the through groove 12 to move upward. The limiting block 14 lifts the lifting plate 13, which rises and falls synchronously with the carrier plate 9. During the pressure working state, the lifting plate 13 always remains flush with the surface of the carrier plate 9. The upper part of the through groove 12 is completely blocked by the lifting plate 13. Only during the cooling process does the lifting plate 13 overcome the limitation of the limiting block 14 and slide upward, breaking away from the flush state to lift and dissipate heat. This avoids the problem that after the carrier plate 9 has a large area of ​​hollowed-out area on the surface, when the vacuum glass 11 is pressure sealed, the glass above the hollowed-out through groove 12 has no support point, the glass is subjected to uneven force, and stress concentration is very likely to cause the glass to break, resulting in a decrease in product yield.

[0030] like Figures 3-10 As shown, in a preferred embodiment of the present invention, the linkage component further includes a top column 16, which is fixedly installed on the U-shaped frame 7. When the carrying plate 9 descends, the top column 16 abuts against the bottom of the lifting plate 13, causing the lifting plate 13 to slide and rise within the through groove 12. When the carrying plate 9 rises so that the second protrusion 902 aligns with the transverse groove 702, both the carrying plate 9 and the lifting plate 13 are located above the top column 16.

[0031] In practical application, after the edge sealing is completed, the drive source drives the lifting frame 3 and the carrying plate 9 to fall vertically downwards as a whole. The carrying plate 9 and the lifting plate 13 move downwards synchronously. The top of the fixed top column 16 abuts against the bottom surface of the lifting plate 13. The lifting plate 13 cannot continue to descend due to the obstruction of the top column 16, while the carrying plate 9 continues to move downwards. The two generate relative displacement, and the lifting plate 13 slides upwards relative to the carrying plate 9, automatically lifting the graphite paper 10 and vacuum glass 11 above. After cooling is completed, the carrying plate 9 is raised again, and the lifting plate 13 is released from the limit of the top column 16 and automatically falls back to its original position under the action of gravity. This is suitable for the high-temperature working environment of the edge sealing furnace.

[0032] like Figures 8-10 As shown, in a preferred embodiment of the present invention, the top of the lifting plate 13 is provided with a plurality of equally spaced grooves 1301.

[0033] In practical application, when the lifting plate 13 lifts the graphite paper 10 upwards, the top surface of the lifting plate 13 forms multiple straight-through heat dissipation channels with the graphite paper 10 through the groove 1301. The hot air flowing in the furnace can directly pass through the groove 1301 and pass through the bottom of the graphite paper 10, directly contacting the bottom surface of the vacuum glass 11 for heat exchange and heat dissipation. This avoids the problem that when the top surface of the flat lifting plate 13 is in large-area contact with the graphite paper 10, there are still local heat dissipation dead corners and the bottom heat dissipation efficiency is limited.

[0034] like Figures 8-10 As shown, in a preferred embodiment of the present invention, a plurality of fixed plates 15 are fixedly installed in the through groove 12 at equal intervals. Each fixed plate 15 is slidably connected to the groove 1301, and the top of the fixed plate 15 is flush with the top of the carrying plate 9.

[0035] In practical application, after the groove 1301 is opened in the lifting plate 13, the support of the plate surface is discontinuous, and the glass is subjected to uneven stress in some areas when pressure is applied, so there is still a risk of minor breakage. Figure 9 As shown in the example, during the lifting and lowering movement of the lifting plate 13, the groove 1301 slides vertically along the outer wall of the fixed plate 15. The fixed plate 15 remains fixed inside the through groove 12. During the pressure sealing stage, the fixed plate 15 and the lifting plate 13 together form a complete and flat support plane, fully covering the hollow area of ​​the through groove 12. During the lifting and heat dissipation stage, the fixed plate 15 separates each groove 1301 to ensure that each heat dissipation duct has a uniform size and uniform ventilation.

[0036] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
