[0028] When float glass comes into contact with a solution containing hydrofluoric acid, chemically strengthened glass is easily corroded. Therefore, the controllable hydrofluoric acid corrosion process is also used as an effective glass surface etching technology. At the same time, hydrofluoric acid treatment, through chemical reaction with the glass surface, removes the micro-crack layer on the glass surface or clocks the crack tip to hinder the crack propagation, thereby achieving the effect of improving the strength of the glass. Treating chemically strengthened glass with hydrofluoric acid for a certain period of time can improve the surface mechanical properties, especially the impact resistance.

[0029] At present, more than 90% of the flat glass used is produced by the float process. In the production process of float glass, the molten glass liquid needs to be spread on the surface of the molten tin liquid, causing some tin ions to diffuse into the glass surface in contact with the tin liquid, thus forming two surfaces with different chemical compositions and structures, usually referred to as the "air surface" and the "tin surface". The difference in composition and structure causes different surface compressive stresses and stress layer depths on the two surfaces of float glass during the chemical strengthening process. In addition, in order to prevent the glass from being scratched during the production process of float glass, sulfide gas is used to support the glass, which will cause some sulfides to enter the glass surface. When the glass is etched with acid, it will show a dot-shaped "sulfur mark", resulting in a poor appearance of the cover glass.

[0030] like Figure 1 and Figure 2As shown, the device for improving the impact resistance of float glass in the embodiment of the present application includes: an acid tank assembly 10 and a cleaning assembly 20. The acid tank assembly 10 includes an acid tank 11, a pickling roller structure 12 and an acid tank roller driving structure 13. The acid tank roller driving structure 13 cooperates with the pickling roller structure 12. The pickling roller structure 12 includes a plurality of pickling rollers, each of which is rotatably installed in the acid tank 11. The plurality of pickling rollers are arranged at intervals. The liquid level of the acid tank 11 is H, the upper section of the pickling roller is h1, and the thickness of the float glass is h2, and h1≤H

[0031] By applying the technical solution of this embodiment, after the float glass enters the acid tank assembly 10, since h1≤H

[0032] like Figure 1 As shown, in some embodiments, the pickling roller includes a carbon fiber central shaft and a rubber coating, the rubber coating is arranged on the circumferential outer side of the carbon fiber central shaft, and the inner depth of the acid tank 11 is h, and H<h≤h1+h2 is satisfied. The materials of the carbon fiber central shaft and the rubber coating are not easily corroded by acid and have a relatively long service life. The acid in this embodiment is hydrofluoric acid. The inner depth of the acid tank 11 is h, and H<h≤h1+h2 is satisfied, so that the float glass can be automatically transmitted, and the float glass can be transported from the acid tank 11 to the second transition structure 15 by the rotation of the conveying roller. It should be noted that the conveying of the float glass can also be achieved by setting a structure. For example, guide rollers are respectively arranged at both ends of the acid tank 11, and the guide rollers are higher than the pickling roller structure 12, so that the section of the pickling roller closest to the guide roller forms a range of 0.5° to 3.5°, so that the float glass is not easily interfered with the acid tank 11, and the float glass can be smoothly moved. The structure of the rollers makes the contact area between the float glass and the rollers relatively small, and the float glass runs relatively smoothly, so that the pickling of the float glass is more uniform. The spacing between adjacent pickling rollers is less than or equal to 5 cm.

[0033] like Figure 1 ​​As shown, in some embodiments, the acid tank assembly 10 further includes a first transition structure 14, which is disposed on a side of the acid tank 11 away from the cleaning assembly 20. The first transition structure 14 can be provided to prepare for the float glass entering the acid tank 11 to return to its original position in advance. For example, guide plates are provided on both sides of the float glass moving.

[0034] like Figure 1 As shown, in some embodiments, the first transition structure 14 includes a first transition bracket and a plurality of first transition conveying rollers, and the plurality of first transition conveying rollers are rotatably arranged on the first transition bracket. The plurality of first transition conveying rollers cooperate to transmit float glass, the acid tank roller driving structure is connected to the first transition conveying rollers through a reduction gear, and the first transition conveying rollers and the pickling roller structure are connected through a constant speed gear. Gears are arranged at the ends of the first transition conveying rollers and the pickling roller structure, and the structure of the gear meshing transmission is not repeated here.

[0035] like Figure 1 As shown, in some embodiments, the acid tank assembly 10 further includes a second transition structure 15, and the second transition structure 15 is arranged between the acid tank 11 and the cleaning assembly 20. The arrangement of the second transition structure 15 can help the float glass after pickling to smoothly enter the cleaning assembly 20, and can reduce the adhesion of acid to the float glass entering the cleaning assembly 20. It should be noted that the second transition structure 15 includes a second transition bracket and a plurality of second transition conveying rollers, and each second transition conveying roller is rotatably arranged on the second transition bracket. An acid receiving groove is arranged at the lower part of the second transition conveying roller for receiving the acid dripping from the float glass.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the acid pool assembly 10 also includes a cover structure 16 and a negative pressure structure 17, the cover structure 16 is covered on the upper side of the acid pool 11, the first transition structure 14 and the second transition structure 15, the cover structure 16 includes a cover body and a negative pressure channel, the negative pressure channel is connected to the cover body, and the negative pressure structure 17 is connected to the negative pressure channel. The setting of the negative pressure structure 17 can effectively protect the environment, the acid has a certain volatility, and the volatile acid mist is discharged through the negative pressure structure 17, so that the body of the staff can be protected from the harm of the acid mist. It should be noted that the cover body has an opening, the negative pressure channel is connected to the opening of the cover body, the negative pressure structure 17 is arranged in the negative pressure channel, and the opening of the cover body corresponds to the first transition structure 14.

[0037] like Figure 1As shown, in some embodiments, the cleaning assembly 20 includes a rinsing structure 21 and a pure water cleaning structure 22, and the rinsing structure 21 is located between the second transition structure 15 and the pure water cleaning structure 22. The rinsing structure 21 and the pure water cleaning structure 22 are independently arranged, that is, the liquid in the rinsing structure 21 will not affect the liquid in the pure water cleaning structure 22. Such a structure makes the cleaning of the float glass cleaner. The pH of the liquid in the rinsing structure 21 is adjusted between 8 and 11. The pure water cleaning structure 22 is also divided into multiple sections of independent pure water pools, which can better ensure the cleaning effect of the float glass. The pure water cleaning structure 22 includes a pure water pool, a nozzle and a plurality of cleaning conveying rollers, each of which is rotatably arranged in the pure water pool, and the upper surface of the cleaning conveying roller is far below the clean water liquid level, so that the float glass can be completely immersed in the clean water, and the nozzle is located at the upper part of the pure water pool, so that even if the float glass leaks out of the liquid surface, it can be cleaned without missing dead corners.

[0038] like Figure 1 As shown, in some embodiments, the rinsing structure 21 includes a rinsing tank and a plurality of rinsing conveying rollers, and the plurality of rinsing conveying rollers are rotatably arranged in the rinsing tank; the pure water cleaning structure 22 includes a cleaning tank and a plurality of cleaning conveying rollers, and the plurality of cleaning conveying rollers are rotatably arranged in the cleaning tank. The above structure ensures a good cleaning effect of the float glass, and the contact area between the float glass and the rinsing conveying rollers is relatively small. For the same reason, the contact area between the float glass and the cleaning conveying rollers is relatively small.

[0039] like Figure 1 As shown, in some embodiments, the device further includes a drying component 30, which is arranged on a side of the pure water cleaning structure 22 away from the rinsing structure 21. The arrangement of the drying component 30 further ensures the cleanliness of the float glass. For example, wet float glass is easily contaminated with dust. It should be noted that the drying component 30 blows out clean air, and the clean air has a certain temperature, which improves the float glass.

[0040] like Figure 1 As shown, in some embodiments, the device further includes a feed assembly 40 and a discharge assembly 50. The feed assembly 40 is arranged on the side of the first transition structure 14 away from the acid tank 11, and the discharge assembly 50 is arranged on the side of the blow-drying assembly 30 on the principle of the acid tank 11. The setting of the discharge assembly 50 is convenient for placing the float glass, and the setting of the discharge assembly 50 is convenient for taking the float glass. The feed assembly 40 and the discharge assembly 50 of this embodiment are both conveyed by roller structures, which will not be repeated here. A detector is arranged on the discharge assembly 50 to detect whether the float glass is located at a predetermined position of the discharge assembly 50, so as to facilitate the grabbing of the grabbing suction cup.

[0041] It can be seen from the above that the acid liquid driving structure includes an acid liquid driving motor, which is connected to the pickling roller structure 12 through gears, and each pickling roller structure 12 is connected through gears or chains. The float glass is transmitted through a plurality of pickling rollers arranged at intervals. Such a transmission method can not only realize the transmission of the float glass, but also ensure that the contact between the float glass and the acid liquid is not affected. It should be noted that the highest point of the acid liquid pool is slightly higher than the cross-section of the top of the pickling roller, which is 0.8mm to 3.5mm higher.

[0042] The pickling roller includes a carbon fiber center shaft and a rubber coating, wherein the rubber coating is arranged on the circumferential outer side of the carbon fiber center shaft, and the carbon fiber center shaft is rotatably sealed and arranged on the upper part of the acid tank. The above structure ensures that the pickling roller structure 12 has a relatively controllable conveying efficiency and precision for float glass, and on the other hand, it also ensures that the roller structure does not react with the acid, thereby extending the service life. The acid tank 11 is sealed and installed with the pickling roller. It should be noted that the outer surface of the rubber coating has an anti-slip surface, and the anti-slip surface includes a plurality of protrusions, which not only increases the friction between the rubber coating and the float glass, but also ensures that the acid passes through the gaps between the protrusions, so that the reaction between the float glass and the acid is more uniform.

[0043] In some embodiments, the float glass is transferred from the first transition structure 14 to the acid tank 11, and then transferred to the second transition structure 15 through the acid tank 11. The pickling roller of the first transition structure 14 close to the acid tank assembly has an inclination angle of 0.5° to 3.5° with the section of the pickling roller of the acid tank 11 close to the first transition structure 14. The above structure ensures that the float glass can smoothly enter the acid tank 11. If the inclination angle is too small, the acid is easy to overflow from the acid tank. If the inclination angle is too large, the float glass is easy to get stuck with the pickling roller, resulting in the float glass being unable to smoothly pass through the acid tank 11. It should be noted that the free end of each protrusion is an arc surface, and the height of each protrusion is the same, between 3.6mm and 8mm. The height of the protrusion is higher than the thickness of the float glass. In this way, even if the float glass and the roller structure are stuck, the float glass can be driven to move forward by the rotation of the roller structure. The height of each protrusion cannot be too high, otherwise the float glass transportation will be unstable.

[0044] In some embodiments, the acid is hydrofluoric acid. The concentration of hydrofluoric acid is between 2% and 6%, so that the surface effect of the float glass after the reaction is better. The reaction product of hydrofluoric acid and float glass will not remain on the float glass.

[0045] In some embodiments, etching amount = etching rate * etching section length L / roller speed. Through the above formula, the relationship between the acid tank 11 and the float glass can be accurately estimated, for example, the length of the acid tank 11 is between 1.2m and 3.2m. The roller speed refers to the roller speed of the pickling roller.

[0046] In some embodiments, the acid etching rate is between 1um / min and 3um / min, and the etching amount is between 0.5um and 5um. If the etching amount is too large, the strength of the float glass will be affected, and if the etching amount is too small, the defects on the five surfaces of the float glass are not easy to eliminate. The above etching rate and etching amount can not only eliminate defects such as microcracks on the five surfaces of the float glass, but also improve the drop ball strength of the float glass.

[0047] In the technical solutions of some embodiments, it is also necessary to blow dry the float glass cleaned by the cleaning assembly 20. This can increase the discharge rate of the float glass and is also conducive to ensuring the cleanliness of the float glass. The drying air needs to be clean gas with a certain temperature, such as compressed air, which needs dust removal, filtration and other processes to ensure the cleanliness of the float glass.

[0048] In some embodiments, the pH value of the rinse solution is between 8 and 11, and the pure water cleaning structure 22 includes multiple independent pure water pools. Such a rinse solution can not only neutralize the acid solution on the float glass, but also ensure that the rinse solution will not cause adverse effects on the float glass, such as the reaction between the alkali solution and the float glass.

[0049] From the above, it can be known that the five-sided etching equipment of the present application includes eight parts: a feeding section (feeding component 40), a first transition section (first transition structure 14), an acid etching section (acid pool 11), a second transition section (second transition structure 15), a pure water rinsing (alkali neutralization) section (rinsing structure 21), a pure water washing 1 / 2+DT washing section (pure water cleaning structure 22), an air knife drying section (drying component 30), and a discharging section (discharging component 50). The entire system is in a negative pressure state, and the negative pressure pipe is connected to the acid treatment tower. The acid etching section is the key section of the equipment, which requires high operating accuracy, stable glass operation, and liquid level control accuracy controllable within ±0.1mm. Acid etching section liquid level control description: The etching section is equipped with an etching liquid level sensor, which is interlocked with the etching liquid replenishing pump to achieve the purpose of precise liquid level control.

[0050] The high-precision roller structure (pickling roller structure 12) requires that the material should be resistant to hydrofluoric acid, have good rigidity, no deformation, and high coaxiality to ensure the stability of glass operation: the core of the rubber-coated shaft is The 12mm through-axle is made of carbon fiber. The coaxiality tolerance of the rubber-coated axle is 0.02mm, and the total runout tolerance is 0.05mm. The hardness of the rubber-coated axle is 40 degrees, and it is not easy to bend and deform.

[0051] In the etching section, the pickling roller is driven to operate by its rotation. During the operation, the air surface of the glass and the surrounding areas (four raised surfaces) undergo chemical etching reaction with the etching liquid (acid solution).

[0052] The amount of etching can be controlled by the speed of the roller (pickling roller) (i.e. the residence time of the glass in the acid solution) and the concentration of fluoride ions in the acid solution. Etching amount = etching rate * etching section length L / roller speed.

[0053] The key points of the process technology for improving the impact resistance of float high-aluminum glass include two aspects: one is that the etching rate requires the acid etching rate to be optimal at 1-3um / min, and the other is that the etching amount is required to be 0.5-5um. Under this process condition, the impact resistance of the glass is significantly improved. This application scheme takes 1.3mm thick float high-aluminum glass as an example, but the verification test is not a condition to limit the scope of the application. Other types of process types for five-sided etching of float glass to improve the impact resistance of glass are within the scope of protection of the patent rights (including but not limited to tin surface coating, inkjet printing, etc.). The verification reference data are as follows:

[0054] Table 1

[0055]

[0056] Note: The drop ball test is carried out in accordance with the standard GB4943.1-2011.

[0057] As shown in Table 1, the average impact height of the ring drop in the five-side etching process is about 150 cm, which is about 50 cm higher than that of the glass substrate (96 cm) that has not been etched.

[0058] The design of the acid etching section of the five-sided etching equipment requires high operating accuracy, smooth glass operation, and liquid level control accuracy of ±0.1mm. The etching section is equipped with a liquid level sensor and interlocked with the liquid replenishment pump to achieve dynamic liquid replenishment to ensure that the etching liquid height is at a controlled height.

[0059] During the process, it is necessary to ensure that the tin surface of the glass substrate does not react with the acid solution, that is, the tin surface must be higher than the etching solution level. In this case, the high-precision rubber roller of the etching section is required to be processed according to the following requirements:

[0060] The core of the rubber-coated shaft is The 12mm through-axle is made of carbon fiber. The coaxiality tolerance of the rubber-coated axle is 0.02mm, and the total runout tolerance is 0.05mm. The rubber-coated hardness is 40 degrees, and it is not easy to bend and deform. The improvement of impact performance requires that the etching rate of the acid solution is best at 1 to 3um / min, and the etching amount is required to be 0.5 to 5um.

[0061] Description of the etching rate control method: by controlling the hydrofluoric acid concentration Wt in the etching reaction acid solution to be 3-5%.

[0062] Description of the etching amount control method: The etching amount can be controlled by the roller speed (i.e. the residence time of the glass in the acid solution) and the fluoride ion concentration in the acid solution. Etching amount = etching rate * etching section length L / roller speed.
