Description

Technical Field

[0001] This application relates to the technical field of glass production, especially colorless high-transparency low-reflection glass and its preparation process. Background Art

[0002] The production principle of low-reflection glass is mainly to improve the light transmittance by reducing the reflectivity of the glass surface. This is usually achieved by coating one or more special thin films on the glass surface. This thin film can cause the reflected light and the transmitted light to interfere with each other and cancel each other out, thereby reducing the reflectivity.

[0003] Before coating the glass, it is necessary to clean both sides of the glass surface simultaneously. In order to prevent oxides, scale, mineral deposits, etc. on the glass surface from affecting the subsequent coating quality, in the prior art, water washing is usually used to clean the glass surface. However, this method has low efficiency. Therefore, this application provides a colorless high-transparency low-reflection glass and its preparation process. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of this application is to provide a colorless high-transparency low-reflection glass and its preparation process to solve the technical problems in the background art.

[0005] The above purpose of this application is achieved through the following technical solutions: The preparation process of colorless high-transparency low-reflection glass includes the following steps:

[0006] S1. Set up a transport rack for transporting the glass substrate, and place the glass substrate on the transport rack;

[0007] S2. Set up a coating device to evenly coat the glass substrate with an acidic cleaning solution;

[0008] S3. Heat the glass substrate to accelerate the reaction rate:

[0009] S4. Clean the glass substrate after the reaction is completed, and then coat the outer layer of the glass substrate;

[0010] S5. Let the glass substrate stand still after coating to complete the coating.

[0011] By adopting the above technical solutions, first, set up a transport rack for stably transporting the glass substrate to ensure that the glass substrate is placed on it flat and without damage, laying a solid foundation for subsequent processing. Then, configure a coating device, which must have the ability to coat evenly, so as to evenly coat the glass substrate surface with an acidic cleaning solution, effectively removing surface stains and impurities, and creating good conditions for subsequent coating.

[0012] The pre-treated glass substrate is then heated to accelerate the chemical reaction between the acidic cleaning solution and the stains, improve cleaning efficiency, and ensure that the glass surface reaches a highly clean state. After heating, a thorough cleaning operation is performed to remove all residues in preparation for the coating process.

[0013] Entering the coating stage, advanced coating technology, such as magnetron sputtering, is used to accurately deposit one or more layers of anti-reflection film on the outer layer of the glass substrate. This film layer is exquisitely designed to effectively reduce the reflection of light on the glass surface, significantly improve light transmittance, and maintain visual clarity and comfort.

[0014] Finally, after the coating is completed, let the glass substrate stand for a period of time to ensure that the coating layer is fully cured and firmly adheres to the glass surface to achieve long-term stable performance.

[0015] Furthermore, the coating device includes a support frame fixedly connected to the upper and lower ends of the transport frame, a cleaning frame is arranged in the middle of the support frame, a roller coating shaft and a coating shaft are rotatably arranged on the cleaning frame, a placement container for acid cleaning liquid is fixedly arranged on the cleaning frame, a sponge body is evenly and fixedly connected to the outer side of the coating shaft and the roller coating shaft, and a linkage device for synchronous two-axis movement is arranged on one side of the roller coating shaft and the coating shaft.

[0016] By adopting the above technical solution, after the glass is placed on the transport rack, as the transport rack starts, the glass to be cleaned is moved to the support rack position, and the sponge on the outside of the coating shaft will come into contact with the acidic cleaning liquid. Through the setting of the linkage device, the roller coating shaft will rotate together. Since the sponges on the roller coating shaft and the coating shaft are close together, the cleaning liquid on the sponge on the roller coating shaft will penetrate into the sponge on the roller coating shaft, and the cleaning liquid will be evenly smeared on the glass substrate as the glass passes by. Pickling utilizes the chemical reaction between acid and stains on the glass surface (such as oxides, scale, mineral deposits, etc.) to convert the stains into salts or other compounds soluble in acid solution, thereby removing them from the glass surface.

[0017] Furthermore, the transport frame is rotatably provided with a plurality of transport shafts, the transport shafts are evenly provided with a plurality of movable plates for moving the glass, the transport frame is fixedly provided with a driving motor, the output end of the driving motor is fixedly provided with a driving gear, one of the transport shafts on the transport frame is fixedly provided with a driven gear meshing with the driving gear, and the plurality of transport shafts are sleeved with synchronous transport belts.

[0018] By adopting the above technical solution, the driving motor is set to drive the transport shaft to rotate, so that the moving plate drives the glass substrate to be transported, and the synchronous transport belt can drive all the transport shafts to move together at the same time.

[0019] Further, the linkage device includes a driving gear fixedly connected to one side of the coating shaft, a driven gear fixedly arranged on the roller coating shaft and meshing with the driving gear, a rotating motor fixedly arranged on the cleaning frame, the output end of the rotating motor is fixedly connected to the coating shaft, and an extrusion device is arranged on one side of the support frame close to the cleaning frame.

[0020] By adopting the above technical solution, after the coating shaft is driven to rotate by the rotating motor, the driving gear drives the driven gear of the roller coating shaft, thereby completing synchronous linkage.

[0021] Further, the extrusion device includes an extrusion spring fixedly connected to the support frame, the other end of the extrusion spring is fixedly connected to the cleaning frame, plug-in frames are fixedly arranged at both ends of the cleaning frame, a plug-in rod fixedly connected to the support frame is inserted into the plug-in frames, and a limiting plate for preventing the plug-in rod from detaching from the plug-in frames is fixedly arranged at the end of the plug-in rod. A heating device is also arranged on the transport frame.

[0022] By adopting the above technical solution, considering that the substrate thicknesses of some glasses are different, the distance between the roller coating shafts can be changed in this application. When a relatively thick glass substrate moves between the roller coating shafts, it will squeeze the extrusion springs on both the upper and lower sides, thereby lifting the roller coating shafts and changing the distance between the two roller coating shafts.

[0023] Further, the heating device includes a heating frame connected to the transport frame, heating lamps are evenly arranged on the heating frame, a connecting device with the cleaning frame is arranged on the heating frame, and a blowing device is also arranged on the heating frame.

[0024] By adopting the above technical solution, in order to accelerate the reaction rate between the cleaning liquid and the impurities on the glass substrate, the temperature is increased by the heating lamps in this application, thereby increasing the reaction rate between the acid and the impurities.

[0025] Further, the connecting device includes linkage plates fixedly connected to both ends of the cleaning frame, connecting plates are fixedly arranged at the other ends of the linkage plates, the length of the connecting plates is the same as the length of the heating frame, and the connecting plates and the heating frame are fixedly connected together by bolts.

[0026] By adopting the above technical solution, the setting of the linkage plates can change the distance between the heating lamps and the glass according to glasses of different thicknesses, thereby preventing damage to the glass caused by the too close distance between the lamps and the glass.

[0027] Further, the blowing device includes a blowing frame fixedly arranged at the upper end of the heating frame, a fan is arranged in the middle of the blowing frame, and a flow dividing device is arranged between the blowing frame and the heating frame.

[0028] By adopting the above technical solution, blowing air can accelerate the air flow on the surface of the glass substrate, thereby accelerating the heat transfer. This helps to shorten the heating time and improve the production efficiency. The flow splitting device can ensure that the air flow evenly covers the surface of the glass substrate, thus avoiding problems such as local overheating or uneven temperature. This helps to improve the quality and uniformity of the coating and reduce the defective rate. During the heating process, blowing air can also accelerate the chemical reaction between the acidic cleaning solution and the stains on the surface of the glass substrate. This helps to remove the stains faster and improve the cleaning effect.

[0029] Furthermore, the flow splitting device includes a blowing plate fixedly connected to the blowing frame. A plurality of groups of through holes are evenly formed in the blowing plate, and blowing cylinders are fixedly connected in the through holes. Flow channels are formed in the blowing cylinders, and the flow channels are evenly distributed in the blowing cylinders. Horn-shaped guiding tubes are arranged at both ends of the blowing cylinders, and the guiding tubes and the blowing cylinders are integrally formed.

[0030] By adopting the above technical solution, the through holes evenly formed in the blowing plate and the flow channels in the blowing cylinders can ensure that the air flow generated by the fan can be evenly distributed after passing through the flow splitting device. The evenly distributed air flow helps to maintain the temperature uniformity on the surface of the glass substrate during the heating process and avoid problems such as local overheating or uneven temperature. The uniform air flow distribution can accelerate the air flow on the surface of the glass substrate, thereby improving the heating efficiency. By optimizing the air flow path, the heat loss during the heat transfer process can be reduced, further improving the heating efficiency. The horn-shaped guiding tubes can effectively guide the air flow out of the blowing cylinders and make it diffuse along a predetermined direction. This design helps to ensure that the air flow can evenly cover the surface of the glass substrate and improve the heating and cleaning effects. The horn-shaped design of the guiding tubes can reduce the resistance of the air flow when flowing out of the blowing cylinders, thereby increasing the flow rate and flow volume of the air flow. This helps to accelerate the air flow on the surface of the glass substrate and improve the heating and cleaning rates.

[0031] Furthermore, for the colorless high-transparency low-reflection glass, in the preparation process of the colorless high-transparency low-reflection glass according to any one of the above technical solutions, it includes antireflection film layers on the upper and lower layers of the glass substrate, and a protective layer is also fixedly arranged outside the antireflection film layers.

[0032] In summary, the present application includes the following beneficial technical effects: Through the automated coating device and transportation system, the continuous, stable transportation and efficient processing of glass substrates are achieved, significantly improving production efficiency. The roller coating shaft and coating shaft in the coating device can evenly apply the acidic cleaning solution, ensuring the cleanliness of the glass substrate surface and laying a good foundation for the subsequent coating process. The design of the linkage device and extrusion device enables the roller coating shaft and coating shaft to automatically adjust according to the thickness of the glass substrate, ensuring the uniformity and adaptability of the coating and further improving product quality. The glass substrate with high cleanliness helps the coating layer to tightly bond with the glass substrate, improving the firmness and stability of the coating layer. The synergistic effect of the heating device and the blowing device accelerates the chemical reaction between the acidic cleaning solution and the stains on the glass substrate surface, removing more stains and providing a cleaner surface for coating. The uniform air flow distribution and heating efficiency contribute to the uniform deposition of the coating layer on the glass substrate, improving the quality and uniformity of the coating.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] The following further describes the present application in detail with reference to the accompanying drawings.

[0041] Example, refer to Figures 1 - 5 , the preparation process of colorless high-transmittance and low-reflection glass, includes the following steps:

[0042] S1. Set up a transport rack 1 for transporting the glass substrate 5, and place the glass substrate 5 on the transport rack 1;

[0043] S2. Set up a coating device to evenly coat the glass substrate 5 with an acidic cleaning solution;

[0044] S3. Heat the glass substrate 5 to accelerate the reaction rate:

[0045] S4. Clean the glass substrate 5 after the reaction is completed, and then coat the outer layer of the glass substrate 5;

[0046] S5. After the coating is completed, let the glass substrate 5 stand still to complete the coating.

[0047] First, set up a transport rack 1 for stably transporting the glass substrate 5 to ensure that the glass substrate 5 is placed on it flat and without damage, laying a solid foundation for subsequent processing. Then, configure a coating device, which must have the ability to evenly coat, so as to evenly coat the surface of the glass substrate 5 with an acidic cleaning solution, effectively removing surface stains and impurities and creating good conditions for subsequent coating.

[0048] Subsequently, heat the pretreated glass substrate 5. This step aims to accelerate the chemical reaction between the acidic cleaning solution and the stains, improve the cleaning efficiency, and ensure that the glass surface reaches a highly clean state. After heating, carry out a thorough cleaning operation to remove all residues and prepare for the coating process.

[0049] Enter the coating stage. Adopt advanced coating technologies, such as magnetron sputtering, to precisely deposit one or more anti-reflection films on the outer layer of the glass substrate 5. This film layer is exquisitely designed, which can effectively reduce the reflection of light on the glass surface, significantly improve the light transmittance, and at the same time maintain clear and comfortable vision.

[0050] Finally, after the coating is completed, let the glass substrate 5 stand still for a period of time to ensure that the coating layer is fully cured and firmly adheres to the glass surface to achieve long-term stable performance.

[0051] In this embodiment, the coating device includes support frames 2 fixedly connected to the upper and lower ends of the transport rack 1. A cleaning frame 21 is arranged in the middle of the support frames 2. A roller coating shaft 26 and a coating shaft 27 are rotatably arranged on the cleaning frame 21. A placement container 271 for placing the acid cleaning solution is fixedly arranged on the cleaning frame 21. Sponge bodies 20 are evenly fixedly connected to the outer sides of the coating shaft 27 and the roller coating shaft 26. A linkage device for synchronously moving the two shafts is arranged on one side of the roller coating shaft 26 and the coating shaft 27.

[0052] After placing the glass on the transport rack 1, as the transport rack 1 starts, the glass to be cleaned is moved to the position of the support rack 2. The sponge body 20 outside the coating shaft 27 will come into contact with the acidic cleaning liquid. Through the setting of the linkage device, the roller coating shaft 26 will rotate together. Since the sponge bodies 20 on the roller coating shaft 26 and the coating shaft 27 are close to each other, the cleaning liquid on the sponge body 20 of the roller coating shaft 26 will penetrate into the sponge body 20 on the roller coating shaft 26. As the glass passes by, the cleaning liquid will be evenly applied to the glass substrate 5. Acid pickling utilizes the chemical reaction between an acid and stains on the glass surface (such as oxides, scale, mineral deposits, etc.) to convert the stains into salts or other compounds soluble in the acid solution, thereby removing them from the glass surface.

[0053] In this embodiment, a plurality of transport shafts 11 are rotatably arranged on the transport rack 1. A plurality of moving disks 12 for moving the glass are evenly arranged on the transport shafts 11. A driving motor 13 is fixedly arranged on the transport rack 1. A driving gear 14 is fixedly arranged at the output end of the driving motor 13. A driven gear 15 meshing with the driving gear 14 is fixedly arranged on one of the transport shafts 11 on the transport rack 1. A synchronous transport belt 16 is sleeved on the plurality of transport shafts 11.

[0054] Through the setting of the driving motor 13, the transport shaft 11 is driven to rotate, so that the moving disk 12 drives the glass substrate 5 to be transported. Through the setting of the synchronous transport belt 16, all the transport shafts 11 can be driven to move simultaneously.

[0055] In this embodiment, the linkage device includes a driving gear 29 fixedly connected to one side of the coating shaft 27. A driven gear 28 meshing with the driving gear 29 is fixedly arranged on the roller coating shaft 26. A rotating motor is fixedly arranged on the cleaning rack 21. The output end of the rotating motor is fixedly connected to the coating shaft 27. An extrusion device is arranged on one side of the support rack 2 close to the cleaning rack 21.

[0056] After the rotating motor drives the coating shaft 27 to rotate, the driving gear 29 drives the driven gear 28 of the roller coating shaft 26, thus completing synchronous linkage.

[0057] In this embodiment, the extrusion device includes an extrusion spring 22 fixedly connected to the support rack 2. The other end of the extrusion spring 22 is fixedly connected to the cleaning rack 21. Plug-in frames 24 are fixedly arranged at both ends of the cleaning rack 21. Plug-in rods 23 fixedly connected to the support rack 2 are inserted into the plug-in frames 24. A limiting plate 25 for preventing the plug-in rods 23 from detaching from the plug-in frames 24 is fixedly arranged at the end of the plug-in rods 23. A heating device is also arranged on the transport rack 1.

[0058] Since the substrate thickness of the partial glass considered is different, the distance between the roller coating shafts 26 can be changed in this application. After the relatively thick glass substrate 5 moves between the roller coating shafts 26, it will squeeze the extrusion springs 22 on the upper and lower sides, thereby lifting the roller coating shafts 26 and changing the distance between the two roller coating shafts 26.

[0059] In this embodiment, the heating device includes a heating rack 4 connected to the transport rack 1. Heating tubes are uniformly arranged on the heating rack 4. A connecting device for the cleaning rack 21 is provided on the heating rack 4, and a blowing device is also provided on the heating rack 4.

[0060] In order to accelerate the reaction rate between the cleaning liquid and the impurities on the glass substrate 5, in this application, the temperature is increased by the heating tubes, thereby increasing the reaction rate between the acid and the impurities.

[0061] In this embodiment, the connecting device includes linkage plates 30 fixedly connected to both ends of the cleaning rack 21. A connecting plate is fixedly arranged at the other end of the linkage plate 30. The length of the connecting plate is the same as the length of the heating rack 4, and the connecting plate and the heating rack 4 are fixedly connected together by bolts.

[0062] The setting of the linkage plates 30 can change the distance between the heating tubes and the glass according to the thickness of different glasses, thereby preventing damage to the glass caused by the distance between the tubes and the glass being too close.

[0063] In this embodiment, the blowing device includes a blowing rack 3 fixedly arranged at the upper end of the heating rack 4. A fan 31 is arranged in the middle of the blowing rack 3, and a flow dividing device is arranged between the blowing rack 3 and the heating rack 4.

[0064] By blowing air, the air flow on the surface of the glass substrate 5 can be accelerated, thereby accelerating the heat transfer. This helps to shorten the heating time and improve the production efficiency. The flow dividing device can ensure that the air flow evenly covers the surface of the glass substrate 5, thereby avoiding problems such as local overheating or uneven temperature. This helps to improve the quality and uniformity of the coating and reduce the defective rate. During the heating process, blowing air can also accelerate the chemical reaction between the acidic cleaning liquid and the stains on the surface of the glass substrate 5. This helps to remove the stains faster and improve the cleaning effect.

[0065] In this embodiment, the flow splitting device includes a blowing plate 32 fixedly connected to the blowing frame 3. A plurality of through holes are evenly formed in the blowing plate 32, and a blowing cylinder 34 is fixedly connected in each through hole. A streamline groove 35 is formed in the blowing cylinder 34, and the streamline grooves 35 are evenly distributed in the blowing cylinder 34. The through holes evenly formed in the blowing plate 32 and the streamline grooves 35 in the blowing cylinder 34 can ensure that the air flow generated by the fan 31 can be evenly distributed after passing through the flow splitting device. The evenly distributed air flow helps to maintain the temperature uniformity on the surface of the glass substrate 5 during the heating process, avoiding problems such as local overheating or uneven temperature. The uniform air flow distribution can accelerate the air flow on the surface of the glass substrate 5, thereby improving the heating efficiency.

[0066] By optimizing the air flow path, the loss of heat during the transfer process can be reduced, further improving the heating efficiency.

[0067] In this embodiment, horn-shaped guide tubes 36 are provided at both ends of the blowing cylinder 34, and the guide tubes 36 and the blowing cylinder 34 are integrally formed. The horn-shaped guide tubes 36 can effectively guide the air flow out of the blowing cylinder 34 and diffuse it along a predetermined direction. This design helps to ensure that the air flow can evenly cover the surface of the glass substrate 5, improving the heating and cleaning effects. The horn-shaped design of the guide tubes 36 can reduce the resistance of the air flow when flowing out of the blowing cylinder 34, thereby increasing the flow rate and flow volume of the air flow. This helps to accelerate the air flow on the surface of the glass substrate 5 and improve the heating and cleaning rates.

[0068] In this embodiment, referring to Figure 6 , for the colorless high-transparency low-reflection glass, applying the preparation process of any one of the above technical solutions for the colorless high-transparency low-reflection glass, it includes antireflection film layers 51 on the upper and lower layers of the glass substrate 5, and a protective layer 52 is also fixedly arranged outside the antireflection film layers 51.

[0069] Specific implementation process: The core components of the coating device include support frames 2 fixedly connected to the upper and lower ends of the transport frame 1. These support frames 2 provide a stable foundation for the coating operation. At the middle position of the support frames 2, a cleaning frame 21 is cleverly arranged. On the cleaning frame 21, a roller coating shaft 26 and a coating shaft 27 are rotatably installed, and a placement container 271 for containing acidic cleaning liquid is also fixed. Spongy bodies 20 are evenly fixed on the outer sides of the roller coating shaft 26 and the coating shaft 27. These spongy bodies 20 are the key components for applying the acidic cleaning liquid. It is particularly worth mentioning that a linkage device is arranged on one side of the coating shaft 27 and the roller coating shaft 26 to ensure that the two can rotate synchronously, thereby efficiently and evenly applying the acidic cleaning liquid onto the glass substrate 5.

[0070] The transportation system realizes the stable transportation of the glass substrate 5 through multiple groups of rotating transportation shafts 11 and the moving disks 12 evenly distributed on the transportation shafts 11. The setting of the driving motor 13, through the meshing of the driving ratchet 14 and the driven ratchet 15, and the cooperation of the synchronous conveyor belt 16, ensures that all the transportation shafts 11 can move the glass substrate 5 synchronously and stably.

[0071] The design of the linkage device is also ingenious. It realizes the synchronous rotation of the coating shaft 27 and the roller coating shaft 26 by the meshing of the driving gear 29 on one side of the coating shaft 27 and the driven gear 28 on the roller coating shaft 26, and the drive of the rotating motor. In addition, an extrusion device is provided on one side of the support frame 2 close to the cleaning frame 21. This device can automatically adjust the distance between the roller coating shafts 26 according to the thickness of the glass substrate 5 through components such as the extrusion spring 22 and the plug-in frame 24, ensuring the uniformity and adaptability of the coating.

[0072] The heating device adopts a heating frame 4 connected to the transportation frame 1. Heating lamps are evenly arranged on the heating frame 4 to increase the temperature of the glass substrate 5 and the acidic cleaning liquid on its surface, thereby accelerating the chemical reaction rate. A connecting device is also provided on the heating frame 4 to allow the adjustment of the distance between the heating lamps and the glass according to the glass thickness to prevent overheating damage. At the same time, a blowing device is equipped on the heating frame 4, including a blowing frame 3, a fan 31, and a flow splitting device. The fan 31 in the blowing frame 3 can accelerate the air flow on the surface of the glass substrate 5, accelerating the heat transfer and the progress of the chemical reaction. The flow splitting device ensures that the air flow can evenly cover the surface of the glass substrate 5 through the flow line grooves 35 on the blowing plate 32 and the blowing cylinder 34, and the horn-shaped guiding tube 36, improving the heating and cleaning effects.

[0073] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of the application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
