Description

Technical Field

[0001] The invention relates to the field of glass, and in particular to a quartz glass box and an annealing device and method for processing the same. Background Art

[0002] Museums are important places for storing and displaying human cultural heritage, and cultural relic protection is the core of museum work, especially some paper cultural relics, ancient calligraphy and painting, precious collections, etc. that are easily affected by environmental changes and need extra care. Therefore, constant temperature and humidity display cabinets came into being. Constant temperature and humidity display cabinets provide a stable and suitable environment, greatly reducing the damage to cultural relics caused by the external environment.

[0003] At present, the glass boxes installed on the constant temperature and humidity display cabinets are generally made of hollow glass. Compared with single-layer glass boxes, hollow glass boxes have good thermal insulation performance, high structural strength, and are not easy to break. However, compared with vacuum glass, the thermal insulation performance of hollow glass is not good enough. Considering that some precious paper cultural relics, ancient calligraphy and paintings, and precious collections are priceless treasures, in recent years, glass boxes made of vacuum glass have been installed on constant temperature and humidity display cabinets. It has gradually become the mainstream choice for museums to purchase constant temperature and humidity display cabinets. Although the cost of glass boxes made of vacuum glass is higher than that of hollow glass boxes, it is acceptable compared with precious paper cultural relics, ancient calligraphy and paintings, and precious collections.

[0004] However, due to the influence of atmospheric pressure and glass properties, it is impossible to completely evacuate the interlayer of the vacuum glass box, otherwise the strong atmospheric pressure will directly crush the vacuum glass plate. Therefore, the glass box made of vacuum glass is not strictly vacuum glass. There is still a proper amount of gas in the interlayer of the vacuum glass box. This is also the fundamental reason why the thermal insulation performance of the glass box made of vacuum glass does not have a huge advantage over the thermal insulation performance of insulating glass. If the application environment of the constant temperature and humidity display cabinet has extremely high requirements for the thermal insulation performance of the glass box, the conventional vacuum glass box is also difficult to apply. Based on this, the present invention is designed. Summary of the invention

[0060] Embodiment 1:

[0061] This embodiment provides a quartz glass box, which is a vacuum glass box made of quartz glass. Quartz glass has higher mechanical strength than ordinary glass, so the vacuum degree in the interlayer of the glass box can be higher, and even a complete vacuum state can be achieved. In this way, the thermal insulation performance of the quartz glass box is greatly improved, and the thermal insulation performance is very excellent, which has a huge advantage over the thermal insulation performance of conventional vacuum glass, and effectively meets the use of occasions with extremely high requirements for the thermal insulation performance of the glass box.

[0062] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the quartz glass box includes: an outer box body 1, an inner box body 2, and a sealing frame 3. The inner box body 2 is located on the inner side of the outer box body 1 and does not contact the inner wall of the outer box body 1, so that a gap 4 is formed between the outer box body 1 and the inner box body 2. The sealing frame 3 is located between the outer box body 1 and the inner box body 2, and is sealed and fixedly connected to the outer box body 1 and the inner box body 2. The sealing frame 3 is flush with the open end surfaces of the outer box body 1 and the inner box body 2, and the sealing frame 3 is used to seal the gap 4; at least the outer box body 1 and the inner box body 2 are made of quartz glass in one piece. In this design, compared with a box body made of multiple glass plates spliced ​​together, there are fewer bonding interfaces, better box sealing performance, and more energy saving. In addition, the exhaust hole 35 is located on the sealing frame 3, which does not affect the beauty of the quartz glass box.

[0063] In this embodiment, if Figure 3As shown, the sealing frame 3 is provided with a through exhaust hole 35, and the gap 4 is connected to the outside through the exhaust hole 35. With this design, after the quartz glass box is installed on the constant temperature and humidity display cabinet, the sealing frame 3 is located at the bottom of the quartz glass box, so the exhaust hole 35 does not affect the beauty of the quartz glass box, and after the outer box body 1 and the inner box body 2 are manufactured by integrally forming quartz glass, there is no need to set the exhaust hole 35 on the surface of the outer box body 1 and the inner box body 2, thereby ensuring the beauty of the quartz glass box.

[0064] Preferably, the cross-section of the sealing frame 3 is an isosceles trapezoid, the side of the sealing frame 3 where the waist of the isosceles trapezoid is located is close to the inner wall of the outer box body 1 and the outer wall of the inner box body 2, and the bottom surface of the sealing frame 3 where the longer lower bottom of the isosceles trapezoid is located is flush with the open end surfaces of the outer box body 1 and the inner box body 2. Such a design is conducive to the crimping and sealing connection between the sealing frame 3 and the outer box body 1 and the inner box body 2, thereby increasing the connection firmness between the sealing frame 3 and the outer box body 1 and the inner box body 2.

[0065] Preferably, the exhaust hole 35 is a conical hole, and the end of the conical hole with a larger aperture is located on the bottom surface of the sealing frame 3. With this design, the conical hole can be plugged and sealed by a conical screw. The design of the exhaust hole 35 as a conical hole is conducive to the conical screw and the conical hole being crimped and sealed and fixedly connected.

[0066] In the present embodiment, after the quartz glass box is installed on the constant temperature and humidity display cabinet, the quartz glass box is inverted, and the sealing frame 3 is located at the bottom of the quartz glass box. The design of the cross section of the sealing frame 3 is an isosceles trapezoid, and the design of the exhaust hole 35 is a conical hole makes the sealing frame 3 subject to the upper outer box body 1 and the inner box body 2 and the lower constant temperature and humidity display cabinet. The upper and lower extrusions are mutually squeezed and the sealing frame 3 is firmly connected to the outer box body 1 and the inner box body 2, and the sealing frame 3 will not shake up and down. Correspondingly, the conical screw is subjected to the upper sealing frame 3 and the lower constant temperature and humidity display cabinet. Mutually squeezed up and down, the conical screw is firmly connected to the sealing frame 3 and will not shake up and down, thereby enhancing the connection firmness of the sealing frame 3 with the outer box body 1 and the inner box body 2 and the connection firmness of the conical screw with the conical hole.

[0067] The quartz glass box of this embodiment is a vacuum glass box made of quartz glass. Quartz glass has higher mechanical strength than ordinary glass, so the vacuum degree in the gap 4 can be higher, and even a complete vacuum state can be achieved. The thermal insulation performance of the quartz glass box manufactured in this way is greatly improved compared with the conventional vacuum glass box, and the thermal insulation performance is very excellent, which effectively meets the use of occasions with extremely high requirements for the thermal insulation performance of the glass box.

[0068] Embodiment 2:

[0069] This embodiment proposes an annealing device for quartz glass box processing of embodiment 1. The annealing device for quartz glass box processing is designed with an annealing support box dedicated to the outer box body 1 and the inner box body 2. The annealing support box can stably support and fix the outer box body 1 and the inner box body 2, avoid local deformation of the outer box body 1 and the inner box body 2 during the annealing process, and affect the quality of the outer box body 1 and the inner box body 2, so as to ensure that the outer box body 1 and the inner box body 2 complete the annealing operation with high quality.

[0070] In addition, the outer box body 1 and the inner box body 2 can be nested together for annealing operations without separate annealing. Without adjusting the annealing device, the annealing speed and efficiency are doubled, which greatly improves the production and processing efficiency of the quartz glass box, reduces production costs, and enhances the company's market competitiveness.

[0071] Specifically, Figure 4-Figure 11 As shown, the annealing device for quartz glass box processing includes: an annealing furnace body 5, a plurality of heat-insulating seat plates 8, an inner support box 24, and an outer support box 12. Figure 4 As shown, a conveyor line body 6 is arranged in the annealing furnace body 5, and the conveyor line body 6 has a plurality of rollers 7; a plurality of heat-insulating seat plates 8 are placed flat on the conveyor line body 6 at equal intervals along the conveying direction, and move horizontally under the drive of the rollers 7, continuously conveying the outer box body 1 and the inner box body 2 into the annealing furnace body 5.

[0072] In this embodiment, if Figure 6-Figure 11 As shown, the inner support box 24 is fixedly connected to the upper surface of the heat insulation seat plate 8. Preferably, as shown in FIG. Figure 7 As shown, the inner support box 24 is supported and fixed on the upper end of the vertically arranged column 25, and the lower end of the column 25 is fixedly connected to the upper surface of the insulation seat plate 8. With this design, the lower end of the inner support box 24 can be designed to be open and not in contact with the upper surface of the insulation seat plate 8, which is beneficial to the internal heat dissipation of the inner support box 24.

[0073] In this embodiment, if Figure 6-Figure 11As shown, the lower end of the side of the inner support box 24 is convex, thereby forming a U-shaped step surface 26, and the inner box body 2 can be placed upside down on the inner support box 24, and the inner wall of the inner box body 2 is in contact with the outer wall of the inner support box 24, and the open lower end surface of the inner box body 2 is in contact with the step surface 26. With this design, the inner box body 2 is firmly supported by the inner support box 24. During the annealing process, the inner box body 2 will not undergo local deformation after being heated, thereby ensuring the quality of the inner box body 2. If the inner box body 2 is directly placed upside down on the upper surface of the heat-insulating seat plate 8, the lower end of the side wall of the inner box body 2 is easily affected by the downward pressure of the inner box body 2 itself, and local deformation occurs during the heating of the inner box 2, causing the surface of the inner box body 2 to bend, affecting the quality of the inner box 2. If the inner box 2 is directly placed on the upper surface of the heat-insulating seat plate 8, it will not be inverted. The bottom surface of the inner box body 2 is blocked by the side panels around it, and the bottom surface of the inner box body 2 is blocked by the heat insulating seat plate 8 below it, which causes the heat emitted by the heat source to pass through the side panels around the inner box body 2 before it can act on the bottom plate of the inner box body 2. This will inevitably cause a temperature difference between the bottom surface and the side surface of the inner box body 2, thereby affecting the annealing quality of the inner box body 2. Therefore, the inner support box 24 of this embodiment is designed and the inner box body 2 is supported by the inverted buckle, which effectively ensures the annealing quality of the inner box body 2. Similarly, the outer support box 12 also supports the outer box body 1 in the same way.

[0074] Specifically, Figure 4-Figure 11 As shown, the outer support box 12 is horizontally slidably installed on the upper surface of the insulation seat plate 8, and the lower end and one end of the outer support box 12 in the horizontal sliding direction are both open. With this design, the outer support box 12 can be horizontally slidably mounted on the outside of the inner box body 2. The design purpose of adopting the horizontal sliding of the outer support box 12 is not to affect the inverted placement of the inner box body 2 on the inner support box 24. After the inner box body 2 is invertedly placed on the inner support box 24, the outer support box 12 is horizontally slidably mounted on the outside of the inner box body 2, and then the outer box body 1 is invertedly placed on the outer support box 12. In this way, the outer box body 1 and the inner box 2 are mounted together for annealing operations without separate annealing. Without adjusting the annealing device, the annealing speed and efficiency are doubled, which greatly improves the production and processing efficiency of the quartz glass box, reduces production costs, and enhances the company's market competitiveness.

[0075] In this embodiment, the outer support box 12 can be horizontally slid and sleeved on the outside of the inner support box 24 without contacting the inner support box 24, and when the inner box body 2 is placed upside down on the inner support box 24, the outer support box 12 can be horizontally slid and sleeved on the outside of the inner box body 2 without contacting the inner box body 2. This design ensures that it does not affect the upside-down placement of the inner box body 2 on the inner support box 24, and the outer box body 1 and the inner box body 2 are sleeved together for annealing operations.

[0076] In this embodiment, if Figure 4-Figure 11 As shown, the lower end of the side of the outer support box 12 is convex, thereby forming a U-shaped step surface 13, and the outer box body 1 can be placed upside down on the outer support box 12, and the inner wall of the outer box body 1 is in contact with the outer wall of the outer support box 12, and the open lower end surface of the outer box body 1 is in contact with the step surface 13. With this design, the outer box body 1 is firmly supported by the outer support box 12. During the annealing process, the outer box body 1 will not undergo local deformation after being heated, thereby ensuring the quality of the outer box body 1.

[0077] Furthermore, in this embodiment, if Figure 8 As shown, the inner support box 24 and the outer support box 12 are embedded with an electric heating device 30 for heating the outer box body 1 and the inner box body 2. Compared with the conventional method of setting a heat source on the annealing furnace body 5 for annealing heating, this heating method has the advantage that it can ensure that during the annealing operation in which the outer box body 1 and the inner box body 2 are nested together, the outer box body 1 and the inner box body 2 are heated evenly and stably, and there is no temperature difference between the outer box body 1 and the inner box body 2, thereby ensuring the annealing quality of the outer box body 1 and the inner box body 2. On the contrary, if the conventional method of setting a heat source on the annealing furnace body 5 for annealing heating is adopted, the inner box body 2 is located on the inner side of the outer box body 1 and is blocked by the outer support box 12. The heat will first pass through the outer box body 1 and the outer support box 12 before acting on the inner box body 2. There will inevitably be a temperature difference between the outer box body 1 and the inner box 2, which will affect the annealing quality of the outer box body 1 and the inner box 2.

[0078] In this embodiment, if Figure 5 As shown, a brush 32 is vertically elastically inserted into the lower surface of the insulation seat plate 8. Specifically, a mounting hole 31 is provided on the lower surface of the insulation seat plate 8. A spring 2 33 is provided at the bottom of the mounting hole 31. The brush 32 is vertically slidably inserted and installed in the mounting hole 31. The upper end of the brush 32 is connected to the spring 2 33. The brush 32 is insulated from the insulation seat plate 8. The lower end of the brush 32 is in sliding contact with a conductive rod 34. The conductive rod 34 is extended along the conveying direction of the conveyor line body 6. With this design, when the conveyor line body 6 drives the insulation seat plate 8 to translate in the annealing furnace body 5, the lower end of the brush 32 can always be in sliding contact with the conductive rod 34 to obtain electricity, thereby providing sufficient and safe electricity for the operation of the electric heating device 30.

[0079] In this embodiment, the wires and signal lines connected to the electric heating device 30 are arranged below the heat-insulating seat plate 8 , and the safety of the wires and signal lines is protected by the heat-insulating effect of the heat-insulating seat plate 8 .

[0080] Specifically, Figure 4-Figure 11 As shown, the heat-insulating seat plate 8 is provided with a slide groove 14 extending along the sliding direction of the outer support box 12, and a slide rod 15 is slidably installed in the slide groove 14, one end of the slide rod 15 is fixedly connected to the outer support box 12, and the other end is connected to one end of a spring 18, and the other end of the spring 18 is connected to the heat-insulating seat plate 8, and the spring 18 is retracted and extended along the sliding direction of the outer support box 12; a rotating cylinder 20 is rotatably installed on the heat-insulating seat plate 8 through a cylinder seat 21, and the axial direction of the rotating cylinder 20 is parallel to the sliding direction of the outer support box 12, and a lever 22 is fixedly installed on one end of the rotating cylinder 20, and the lever 22 is vertically arranged, and the lower end of the lever 22 is connected to the rotating cylinder 20 is connected, and a baffle rod 23 is fixedly installed on the other end of the rotating drum 20. The baffle rod 23 is horizontally arranged, and the slide bar 15 is pressed against the baffle rod 23 under the push of a spring 18. After the rotating drum 20 rotates to drive the baffle rod 23 to separate from the slide bar 15, the compressed spring 18 pushes the outer support box 12 to slide horizontally outside the inner support box 24 through the slide bar 15. This design saves the trouble of manually pushing the outer support box 12 to slide horizontally outside the inner support box 24. It is only necessary to turn the lever 22 to drive the rotating drum 20 to rotate. It is very simple and convenient, making it possible to control the outer support box 12 to slide horizontally outside the inner support box 24 by a robot.

[0081] In this embodiment, if Figure 4-Figure 11 As shown, the spring 18 is sleeved on the guide column 17, the guide column 17 is horizontally slidably connected to the shaft seat 19, and the shaft seat 19 is fixedly connected to the heat insulation seat plate 8; the upper end of the slide rod 15 is connected to the outer support box 12, the lower end of the slide rod 15 passes through the slide groove 14 and is fixedly connected to the slider 16, and the slider 16 is connected to the guide column 17 and the spring 18. This design can ensure that the spring 18 can be extended and retracted along the sliding direction of the outer support box 12.

[0082] In this embodiment, if Figure 8 As shown, the outer support box 12 is located on one side of the inner support box 24, and the other side of the inner support box 24 is provided with a side baffle 27. Figure 4-Figure 11As shown, the side baffle 27 is vertically arranged and fixedly connected to the heat insulation seat plate 8 through the support 28. When the outer support box 12 is horizontally slidably sleeved outside the inner support box 24, the side baffle 27 is located in the outer support box 12 and is vertically aligned with the open end of the outer support box 12. In this design, the lower end of the side of the side baffle 27 that is away from the inner support box 24 is convex, thereby forming a straight-line step surface 3 29, and the step surface 3 29 and the step surface 1 3 are flush with each other and aligned and contacted, thereby forming a U-shaped step surface; when the outer box body 1 is placed upside down on the outer supporting box 12, the side of the side baffle 27 facing away from the inner supporting box 24 is in contact with the inner wall of the outer box body 1, and the step surface 3 29 is in contact with the open lower end surface of the outer box body 1. The outer box body 1 is supported and fixed by the outer supporting box 12 and the side baffle 27 to prevent local deformation of the outer box body 1 after being heated, thereby ensuring the quality of the outer box body 1.

[0083] In this embodiment, if Figure 4-Figure 11 As shown, a slide rail 9 is provided on the upper surface of the heat-insulating seat plate 8, and a slide bar 10 is installed in the slide rail 9 for horizontal sliding. The slide bar 10 is fixedly connected to the lower end surface of the outer support box 12. The slide bar 10 is made of wear-resistant material and is detachably fixedly connected to the outer support box 12. This design facilitates its disassembly and replacement after wear. A limit block 11 is fixedly installed at one end of the slide rail 9. When the outer support box 12 is sleeved outside the inner support box 24, the slide bar 10 conflicts with the limit block 11, and the compressed spring 18 pushes the outer support box 12 to move. The box 12 slides horizontally until the slide bar 10 contacts the limit block 11, and the spring 18 and the limit block 11 are used to ensure the positioning accuracy of the outer support box 12 when it moves into place. This design can ensure that the outer support box 12 is horizontally slidably sleeved outside the inner support box 24 without contacting the inner support box 24, and when the inner box body 2 is placed upside down on the inner support box 24, the outer support box 12 is horizontally slidably sleeved outside the inner box body 2 without contacting the inner box body 2, thereby realizing that the outer box body 1 and the inner box body 2 are sleeved together for smooth annealing operations.

[0084] Embodiment three:

[0085] This embodiment provides an annealing method for processing a quartz glass box, and the annealing device for processing a quartz glass box of the second embodiment is used to perform the following steps:

[0086] S1, start the conveyor line 6 to drive the multiple heat-insulating seat plates 8 thereon to move closer to the annealing furnace body 5;

[0087] S2, when the first heat-insulating seat plate 8 moves to the entrance of the annealing furnace body 5, the conveyor line body 6 is controlled to stop moving;

[0088] S3, control the robot to pick up the inner box 2, and place the inner box 2 upside down outside the inner support box 24, so that the inner wall of the inner box 2 fits with the outer wall of the inner support box 24 and the open lower end surface of the inner box 2 fits with the step surface 26;

[0089] S4, control the robot to separate from the inner box body 2, then go to the outer box body 1 to grab, and place the grabbed outer box body 1 upside down outside the outer support box 12, so that the inner wall of the outer box body 1 fits with the outer wall of the outer support box 12 and the side baffle 27, and the open lower end surface of the outer box body 1 fits with the step surface 13 and the step surface 3 29. The inner box body 2 and the outer box body 1 are each produced by a production line respectively. The newly manufactured inner box body 2 and the outer box body 1 need to be annealed immediately. The robot is set at the end of the two production lines. The head of the annealing device for quartz glass box processing in Example 2 is located at the end of the two production lines. With this design, the robot can go to the two production lines to pick up the inner box body 2 and the outer box body 1, and place the inner box body 2 and the outer box body 1 on the outer support box 12 and the inner support box 24, thereby realizing the fully automatic assembly line production of the quartz glass box in Example 1, without the need for heavy manual participation and assistance, thereby improving the production efficiency of the quartz glass box;

[0090] S5, start the conveyor line 6 to drive the heat-insulating seat plate 8 into the annealing furnace 5 to perform annealing on the outer box 1 and the inner box 2;

[0091] S6, repeat S1-S5, when the next heat-insulating seat plate 8 moves to the entrance of the annealing furnace body 5, the conveyor line body 6 is controlled to stop moving.

[0092] In this embodiment, before placing the inner box 2 upside down outside the inner support box 24 in S3, the electric heating device 30 is first started to heat the outer box 1 and the inner box 2 to prevent the inner box 2 from being broken due to the outer box 1 and the inner box 2 being too low in temperature;

[0093] The outer box body 1 and the inner box body 2 in S5 are annealed by adjusting the heating power of the electric heating device 30. Since the annealing process and annealing temperature of quartz glass are common knowledge, the specific annealing temperature and annealing process steps are not redundantly described in this article.

[0094] In this embodiment, in the process of the robot leaving the inner box body 2 and heading for the outer box body 1 in S4, the robot is controlled to touch the lever 22, which then drives the rotating drum 20 to rotate, so that the baffle 23 is separated from the slide bar 15, and then the compressed spring 18 pushes the outer support box 12 to slide horizontally outside the inner support box 24 through the slide bar 15, and vertically aligns with the side baffle 27, and then the robot places the grasped outer box body 1 upside down outside the outer support box 12. With this design, the robot can operate the outer box body 1 and the inner box body 2 together with fast speed and high efficiency, which is conducive to improving the annealing efficiency.

[0095] In this embodiment, the temperature of the newly manufactured inner box 2 and outer box 1 drops rapidly and their structural strength increases rapidly. Therefore, when the robot's grippers grip the inner box 2 and outer box 1 and place them upside down on the inner support box 24 and the outer support box 12, the inner box 2 and the outer box 1 will not be deformed by the grippers.

[0096] Preferably, the robot is an articulated robot.

[0097] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
