Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a high-precision clean baking device. Background Technology

[0002] During the manufacturing process, glass sheets are typically baked at different temperatures using a baking device. The main purpose is to remove moisture from the glass's interior and surface, ensuring even heating and preventing uneven expansion and contraction caused by moisture, which could lead to cracking or damage. With the development of electronic products such as mobile phones, tablets, and monitors, the requirements for glass sheets are becoming increasingly stringent. Therefore, the development of high-precision, clean, and easily accessible baking devices is crucial for improving the performance and quality of glass sheets.

[0003] Currently, various companies are conducting extensive research and development on glass plate baking devices, as shown in existing patents:

[0004] 1. A glass substrate baking apparatus (publication number CN208368548U) proposes a support mechanism to support the edge of the glass substrate, and hot air is blown onto the glass substrate through small holes on the heating plate to achieve the purpose of baking the glass substrate. This method takes into account the uniformity of heating of the glass substrate, but does not take into account the pollution of the glass substrate by the air, nor does it take into account the convenience of handling and heat dissipation.

[0005] 2. A glass cover baking device (publication number CN218290739U) proposes a glass cover baking device in which the internal baking frame can be rotated to move toward the opening via a threaded rod. This method only improves the convenience of manual operation, without considering the convenience of robotic arm handling or the cleanliness of baking.

[0006] 3. A glass baking fixture (publication number CN211625894U) proposes a baking fixture that uses clamps to vertically place glass plates;

[0007] 4. A display glass substrate baking device (Announcement No. CN115468389B) proposes a display glass substrate baking device including a baking rack, a baking oven, an air supply system and an exhaust system. The baking device can easily maintain and clean the oven walls and components, and can ensure stable and uniform baking temperature. However, it does not take into account the convenience of robotic arms for handling.

[0008] In summary, current glass plate baking machines on the market generally suffer from problems such as uneven baking temperature, insufficient baking cleanliness, and difficulty in handling the plates. Therefore, there is an urgent need to design a high-precision clean baking device. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] Example 1, as Figure 1-5As shown, a high-precision clean baking device of the present invention includes a cavity 1, wherein a feeding heating plate assembly 2 is installed in the cavity 1, and there are two or more feeding heating plate assemblies 2.

[0038] A rear door 3 is provided on the rear side of the cavity 1, and a front door assembly 4 is provided on the front side of the cavity 1. When the rear door 3 and the front door assembly 4 are closed at the same time, the cavity 1 is a sealed chamber.

[0039] The front door assembly 4 includes a front door frame 41, a vacuum exhaust pipe 42, a front movable door 43, and a high-pressure cylinder 44. The front door frame 41 is fixedly installed on the front side of the cavity 1. The front movable door 43 is rotatably installed inside the front door frame 41. The number of front movable doors 43 is the same as the number of the material feeding heating plate assembly 2, and the front movable doors 43 are arranged one-to-one in front of the material feeding heating plate assembly 2. The high-pressure cylinder 44 is fixedly installed inside the front door frame 41. The number of high-pressure cylinders 44 is the same as the number of front movable doors 43, and the high-pressure cylinders 44 drive the front movable doors 43 to open and close one-to-one.

[0040] When the several front movable small doors 43 are closed, a sealed connection is formed between the cavity 1 and the front door assembly 4, the outer end of the vacuum exhaust pipe 42 extends out of the junction box 5, and the inner end of the vacuum exhaust pipe 42 enters the cavity 1.

[0041] The principle is as follows: when the glass plate is placed onto the feeding heating plate assembly 2, the cavity 1 is evacuated through the vacuum exhaust pipe 42 to remove air and impurities from the cavity 1. Then, the feeding heating plate assembly 2 is activated to heat the glass plate. In a vacuum environment, vacuum baking can prevent oxidation and the generation of impurities, and can more accurately control the heating temperature, improve the quality and performance of the baked glass plate, and reduce the resistance to heat transfer, so that the heat is more evenly distributed on the surface and inside of the glass plate, thereby achieving a faster and more uniform drying effect. The glass plate can be put in and taken out by opening and closing the front movable door 43, which facilitates the baking action of the glass plate.

[0042] Furthermore: a junction box 5 is installed on the top side of the front door frame 41, and a top-level air collection box 6 is provided on the upper edge of the front movable door 43. The vacuum exhaust pipe 42 passes through the junction box 5 and is connected to the top-level air collection box 6. The top-level air collection box 6 is interconnected with the cavity 1. The junction box 5 allows for quick arrangement of power cords and facilitates wiring. The top-level air collection box 6 allows for direct vacuuming on the side of the glass plate, effectively removing impurities from the glass plate and ensuring the baking quality of the glass plate.

[0043] Furthermore: the cavity 1 includes an inner cavity 11 and an outer cavity 12. The outer cavity 12 is wrapped around the outside of the inner cavity 11. There are heat insulation gaps 7 on the four sides of the inner cavity 11 and the outer cavity 12, and the gap distance between the heat insulation gaps 7 is different. The heat insulation gaps 7 can be used to block heat transfer, thereby ensuring the temperature in the inner cavity 11, while the outer cavity 12 will not overheat, avoiding burns to the operator.

[0044] Furthermore, several wiring pipes 8 are connected between the inner cavity 11 and the outer cavity 12, and the wiring pipes 8 are arranged one-to-one on the outside of the feeding heating plate assembly 2; which facilitates the wiring of the feeding heating plate assembly 2.

[0045] Furthermore: the feeding heating plate assembly 2 includes a glass support frame 21 and a heating main board 22. The heating main board 22 is installed inside the glass support frame 21, and the glass support frame 21 is fixedly installed inside the cavity 1. The wiring pipes 8 are arranged one-to-one on the outside of the heating main board 22; this facilitates the placement of the glass plate and also facilitates the wiring of the heating main board 22.

[0046] Furthermore: Two support rods 23 are fixedly installed on the glass support frame 21. The support rods 23 are spaced apart above the heating main plate 22. Several connecting rods 24 are fixedly installed on the two support rods 23. Several support blocks 25 are fixedly installed on the connecting rods 24. The support plate, connecting rods 24 and support blocks 25 do not contact the heating main plate 22. The upper end of the support block 25 is located in the middle of two adjacent feeding heating plate assemblies 2. The glass plate can be lifted by using the support rods 23, connecting rods 24 and support blocks 25. When the glass plate is placed on several support blocks 25, since the support blocks 25 do not directly contact the heating main plate 22, uneven heating of the glass plate will not occur, thus ensuring the quality of the glass plate baking in a vacuum environment.

[0047] Furthermore, partition glass 26 is installed on both the upper and lower sides of the heating main board 22, and several heating tubes 27 are fixedly installed inside the heating main board 22. The heat from the heating tubes 27 during operation is evenly transferred through the partition glass 26, thereby achieving balanced heat transfer and evenly heating the glass plate.

[0048] Furthermore, a heat dissipation and ventilation assembly 9 is installed on the outer wall of the cavity 1; this can further cool the outer cavity 12 and prevent burns to the operator.

[0049] Furthermore, the heat dissipation exhaust assembly 9 has a heat dissipation exhaust port 91 formed on its top side, and air inlets 92 formed on its bottom and sides. Hot air can be drawn upward in conjunction with an external exhaust fan to quickly remove the heat from the outer cavity 12, thereby achieving a better heat dissipation effect and effectively preventing the outer cavity 12 from overheating.

[0050] Furthermore, a drain pipe 10 is provided on the bottom side of the cavity 1, which can effectively remove waste liquid from the cavity 1.

[0051] Example 2, as Figure 1 As shown, this utility model discloses a high-precision clean baking device, including a cavity 1, a feeding heating plate assembly 2, a front door assembly 4, and a heat dissipation and exhaust assembly 9. The front side of the cavity 1 is sealed to the front door assembly 4. The front movable door 43 inside the front door assembly 4 is controlled to open and close by a high-pressure cylinder 44, so that the robotic arm can quickly pick up the glass plate on the feeding heating plate assembly 2. The heat dissipation and exhaust assembly 9 is installed on the right side to cool the cavity 1 and prevent the surface temperature of the outer cavity 12 from being too high, thereby preventing high temperature from damaging the air pipe and power cord. There are a total of 5 feeding heating plate assemblies 2 inside, which play a role in preventing the glass plate from being heated.

[0052] like Figure 2 As shown, the cavity 1 includes an inner cavity 11, an outer cavity 12, a rear door 3, a wiring pipe 8, and a drain pipe 10. The inner cavity 11 is connected to the outer cavity 12 through front and rear plates. The heat insulation gaps 7 on its four sides (upper, lower, left, and right) are all at a certain distance to reduce heat loss in the inner cavity 11. The rear door 3 is installed on the rear side of the cavity 1 to facilitate adjustment of the feeding heating plate assembly 2 and to facilitate disassembly and assembly of the feeding heating plate assembly 2. The wiring pipe 8 runs through the outer cavity 12 and the inner cavity 11 to facilitate the power wiring of the heating tube 27 inside the feeding heating plate assembly 2. The drain pipe 10 is located at the bottom of the inner cavity 11, and waste liquid is discharged along the edge.

[0053] like Figure 3 As shown, the feeding heating plate assembly 2 includes a glass support frame 21, a heating main plate 22, a support rod 23, a connecting rod 24, a support block 25, a partition glass 26, and a heating tube 27. The glass support frame 21 is fixed in the inner cavity 11 by screws, providing fixed support for the heating main plate 22 and the support rod 23. The support rod 23, the connecting rod 24, and the support block 25 do not contact the heating main plate 22, thus effectively supporting the glass plate. In order to ensure that the upper and lower surfaces of the glass plate are heated evenly, the upper end of the support block 25 is set in the middle of two adjacent feeding heating plate assemblies 2, so that the upper and lower surfaces of the glass plate are at the same distance from the heating main plate 22, thereby achieving balanced heating. When heating glass plates of different thicknesses, the height of the support block 25 can be adjusted appropriately to keep the glass plate in the middle of the two glass support frames 21. The upper and lower surfaces of the heating main plate 22 are provided with partition glass 26, and the heating tube 27 inside can be evenly heated through the partition glass 26, so that the heat can be evenly transferred to the glass plate.

[0054] like Figure 4As shown, the front door assembly 4 includes a front door frame 41, a vacuum exhaust pipe 42, a front movable small door 43, a high-pressure cylinder 44, a junction box 5, and a top side air collection box. The vacuum exhaust pipe 42 passes through the junction box 5 and connects to the top air collection box 6. The top air collection box 6 is located in front of the feeding heating plate assembly 2 and is interconnected with the chamber. The outer end of the vacuum exhaust pipe 42 is connected to an external vacuum pump to achieve a large negative pressure effect in the inner cavity, preventing substances in the air from damaging the quality of the glass plate during baking. There are 5 front movable small doors 43, with a rotating shaft installed on their upper side and controlled by a high-temperature cylinder for opening and closing. The positions of the front movable small doors 43 and the glass plates correspond to each other, making it easier for the robot to pick up the glass plates from the feeding heating plate assembly 2.

[0055] like Figure 5 As shown, a heat dissipation exhaust port 91 is provided on the upper side of the heat dissipation exhaust assembly 9, and air inlets 92 are provided on the outer side and bottom side of the heat dissipation exhaust assembly 9. The heat dissipation exhaust port 91 is connected to an external exhaust fan. When the exhaust fan is turned on, it can drive the airflow to flow rapidly on the outside of the chamber, thereby reducing the temperature of the surface of the outer cavity 12. The best cooling effect is achieved by using the principle of hot air rising and active exhaust.

[0056] As an embodiment of this utility model: when the glass plate needs to be baked, the high-temperature cylinder extends, causing the front movable door 43 to open. The robotic arm picks up the glass plate to be baked and places it into the inner cavity 11. At this time, the glass plate will be placed on multiple support blocks 25 of the feeding heating plate assembly 2. After all the glass plates are placed in, the high-temperature cylinder retracts, causing the front movable door 43 to close, making the chamber a sealed space. Then, the external vacuum pump is turned on to extract the air from the inner cavity 11. After the air pressure in the inner cavity 11 reaches the set value, the heating tube 27 is started to heat the inner cavity 11. At the same time, the heat dissipation fan is started to dissipate heat from the outer cavity 12. When the temperature of the inner cavity 11 reaches the set value, the heating tube 27 is started to heat the inner cavity 11. Once the set value is reached, the heating element 27 stops working. When the temperature is lower than the set value, the heating element 27 continues to turn on. After baking is complete, the glass plate can be removed from the front movable door 43 using a robotic arm. Vacuuming can achieve a clean baking effect. All actions are computer-controlled, enabling fully automated operation and improving the production efficiency of glass plate baking. Vacuum baking can prevent oxidation reactions and the generation of impurities, thereby allowing for more precise control of the heating temperature, improving the quality and performance of the baked glass plate, and reducing the resistance to heat transfer, allowing heat to be distributed more evenly on the surface and inside of the glass plate, thus achieving a faster and more uniform drying effect.

[0057] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
