Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning equipment technology, and in particular to an automatic glass cleaning device. Background Technology
[0002] Some display devices in related technologies incorporate glass, which provides protection against dust, water, and impacts for the display panel. To improve the product quality of the display device, the glass needs to be cleaned before assembly to remove dust, dirt, and other contaminants from its surface.
[0003] Traditional glass cleaning methods primarily rely on manual labor, which is not only inefficient but also yields inconsistent cleaning results. Some manufacturers have designed glass cleaning equipment that utilizes roller brush cleaning and spray rinsing, significantly improving cleaning efficiency, but the cleaning effect is still not ideal. Utility Model Content
[0004] This application provides an automatic glass cleaning device designed to improve cleaning results.
[0005] The specific technical solution is as follows:
[0006] This application provides an automatic glass cleaning device, comprising: a feeding section including a corona discharge device and multiple first conveying rollers, wherein the first conveying rollers are used to receive and convey glass to be cleaned, and the corona discharge device is used to perform corona treatment on the surface of the glass; a roller brush cleaning section located downstream of the feeding section, wherein the roller brush cleaning section includes a roller brush assembly and multiple second conveying rollers, wherein the second conveying rollers are used to convey the glass, and the roller brush assembly is used to clean the glass; a spraying section located downstream of the roller brush cleaning section, wherein the spraying section includes a first spray head and multiple third conveying rollers, wherein the third conveying rollers are used to convey the glass, and the spray head is used to rinse the glass; a drying section located downstream of the spraying section, wherein the drying section includes a first air knife and multiple fourth conveying rollers, wherein the fourth conveying rollers are used to convey the glass, and the first air knife is used to dry the glass; and a discharging section including multiple fifth conveying rollers, wherein the fifth conveying rollers are used to send the glass out of the automatic glass cleaning device.
[0007] The automatic glass cleaning equipment in this embodiment includes a roller brush cleaning section, a spray section, and a drying section, which can respectively perform roller brush cleaning, spray rinsing, and air drying on the glass. In addition, a corona discharge device is installed in the feeding section. This device can perform corona treatment on the glass surface, removing organic contaminants such as hair and oil stains through corona discharge without generating dust. Therefore, by combining corona treatment, roller brush cleaning, and spray rinsing, both organic and inorganic contaminants can be effectively removed, thereby improving the cleaning effect.
[0008] In some embodiments, the automatic glass cleaning equipment further includes a first air-cutting section located downstream of the feeding section and upstream of the roller brush cleaning section. The first air-cutting section includes a second air knife and a plurality of sixth conveying rollers. The second air knife is used to remove dust from the surface of the glass.
[0009] The first air cutter section is located downstream of the feeding section and upstream of the roller brush cleaning section. This means that the glass passes through the first air cutter section before entering the roller brush cleaning section. The second air knife blows through the glass surface to remove dust and floating dust, thus preventing the dust on the glass surface from contaminating the water in the roller brush cleaning section.
[0010] In some embodiments, the roller brush assembly includes an upper roller brush and a lower roller brush, the upper roller brush being used to clean the upper surface of the glass and the lower roller brush being used to clean the lower surface of the glass; the roller brush cleaning section further includes a plurality of second spray heads, the water spray pressure of the second spray heads being less than the water spray pressure of the first spray head; wherein, a portion of the second spray heads are located above the second conveying roller for spraying the upper surface of the glass; and another portion of the second spray heads are located below the second conveying roller for spraying the lower surface of the glass.
[0011] The roller brush assembly includes an upper roller brush and a lower roller brush. The upper roller brush is used to clean the upper surface of the glass, and the lower roller brush is used to clean the lower surface, ensuring that both surfaces are cleaned. The second spray head is mainly used to wet the glass, which, in conjunction with the roller brush assembly, improves the cleaning effect. Since the purpose of the second spray head is to wet the glass, not to rinse it, its spray pressure does not need to be too high. Therefore, setting the spray pressure of the second spray head lower than that of the first spray head satisfies the need for wetting the glass while also reducing energy consumption.
[0012] In some embodiments, the number of upper roller brushes is greater than the number of lower roller brushes, and the number of second spray heads located above the second conveyor roller is greater than the number of second spray heads located below the second conveyor roller.
[0013] The upper surface of the glass can be used as the inner surface after assembly into the display device, and the lower surface can be used as the outer surface. In this case, the cleanliness level of the lower surface can be lower than that of the upper surface. Therefore, in the roller brush cleaning section, the number of upper roller brushes is greater than the number of lower roller brushes, and the number of second spray heads located above the second conveyor roller is greater than the number of second spray heads located below the second conveyor roller. This allows the upper surface of the glass to be cleaned more thoroughly, thus meeting the requirements for use as the inner surface after assembly into the display device, while ensuring that the lower surface of the glass receives a basic cleaning. This also helps to reduce the number of parts and save costs.
[0014] In some embodiments, the number of the roller brush cleaning sections is multiple; the automatic glass cleaning equipment further includes multiple second air cutting sections, the number of which is equal to the number of the roller brush cleaning sections. Each roller brush cleaning section has a second air cutting section on its downstream side. Each second air cutting section includes a third air knife and multiple seventh conveying rollers. The seventh conveying rollers are used to convey the glass, and the third air knife is used to dry the glass.
[0015] The system comprises multiple roller brush cleaning sections, allowing the glass to undergo multiple cleaning cycles, thus improving the cleaning effect. Additionally, a second air-cutting section, including a third air knife, is located downstream of each roller brush cleaning section to dry the glass. This ensures that the glass is promptly dried after each roller brush cleaning section, removing wash water from its surface. Consequently, the glass achieves a certain level of cleanliness after each cleaning cycle before moving to the next, resulting in a continuous improvement in cleanliness with each subsequent roller brush cleaning cycle.
[0016] In some embodiments, a plurality of the second conveying rollers are distributed in two rows, with the second conveying rollers in the upper row contacting the upper surface of the glass and the second conveying rollers in the lower row contacting the lower surface of the glass.
[0017] Multiple second conveying rollers in the roller brush cleaning section are distributed in two rows, one above the other. The clamping action of the two rows of second conveying rollers on the glass can improve the stability of the glass during the conveying process. This helps to ensure that both the upper and lower roller brushes can effectively wipe the glass, thereby improving the cleaning effect.
[0018] In some embodiments, there are multiple first air knives, wherein the first air knife closest to the discharge section extends in a direction perpendicular to the glass conveying direction, and the angle between the extension direction of the remaining first air knives and the glass conveying direction is less than 90°.
[0019] The drying section employs multiple first air knives. This multi-knife drying process helps prevent water droplets from remaining on the glass surface, ensuring the glass leaves the automatic glass cleaning equipment completely dry. Furthermore, the first air knife closest to the discharge section extends perpendicular to the glass's transport direction, while the remaining first air knives extend at an angle less than 90° to this direction. In other words, the first few first air knives are angled relative to the glass's transport direction, with only the last one perpendicular. This angled arrangement directs water droplets from the glass surface towards its two opposite corners. After multiple air knives, moisture may remain only at these corners, resulting in a smaller area of residual moisture and a larger dried surface. Combined with the single first air knife closest to the discharge section perpendicular to the glass's transport direction, this ensures the glass is thoroughly dried.
[0020] In some embodiments, the angle between the extension direction of the remaining first air knife and the transmission direction of the glass is greater than or equal to 45° and less than or equal to 80°.
[0021] The angle between the extension direction of the remaining first air knives and the transmission direction of the glass is set to be greater than or equal to 45° and less than or equal to 80°. For most rectangular glass, this can achieve the effect of blowing water droplets towards the two opposite corners of the glass, thereby reducing the area of water vapor residue on the glass surface.
[0022] In some embodiments, the number of first spray heads is multiple, with a portion of the first spray heads located above the third conveying roller for rinsing the upper surface of the glass, and another portion of the first spray heads located below the third conveying roller for rinsing the lower surface of the glass; wherein the number of first spray heads located above the third conveying roller is greater than the number of first spray heads located below the third conveying roller.
[0023] There are multiple first spray heads, with some positioned above the third conveyor roller and others below it. This ensures that both the upper and lower surfaces of the glass are rinsed. The upper surface of the glass can be used as the inner surface after assembly into the display device, and the lower surface can be used as the outer surface. In this case, the cleanliness level of the lower surface can be lower than that of the upper surface. Therefore, in the spray section, the number of first spray heads above the third conveyor roller is greater than the number of first spray heads below the third conveyor roller. This allows the upper surface of the glass to be rinsed more thoroughly, achieving a higher level of cleanliness, thus meeting the requirements for use as the inner surface after assembly into the display device, while ensuring the lower surface of the glass achieves a basic level of cleanliness. This also helps reduce the number of first spray heads 31, saving costs.
[0024] In some embodiments, the automatic glass cleaning equipment further includes a first water supply device and a second water supply device. The first water supply device includes a first water tank and a first water pump connected to the first water tank. The first water pump is connected to a first spray head closest to the drying section. The second water supply device includes a second water tank and a second water pump connected to the second water tank. The second water pump is connected to the remaining first spray heads. The first water tank is connected to a tap water source, and the second water tank is configured to collect the water sprayed by the first spray heads when rinsing the glass.
[0025] The first water tank is connected to a tap water source, ensuring that the water in the first tank is clean tap water. Consequently, the water sprayed from the first spray head closest to the drying section is the cleanest tap water. The second water tank is configured to recycle the water sprayed by the first spray head during the glass rinsing process. In other words, the water sprayed by the remaining first spray heads is recycled multiple times. This setup allows for repeated use of the spray water, thus saving water. Furthermore, using the cleanest tap water in the final spray stage helps ensure effective cleaning when the glass leaves the spray section.
[0026] In some embodiments, the automatic glass cleaning equipment further includes a housing, wherein the roller brush assembly, the second conveying roller, the first spray head, the third conveying roller, the first air knife, and the fourth conveying roller are all located inside the housing.
[0027] This ensures that the processes of cleaning the glass with rollers, rinsing with spray, and drying are all carried out in a dust-free environment, thus preventing secondary contamination of the glass during the cleaning process. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0046] Some display devices in related technologies incorporate glass, which provides protection against dust, water, and impacts for the display panel. To improve the quality of the display device, the glass needs to be cleaned before assembly to remove dust, dirt, and other contaminants from its surface.
[0047] Traditional glass cleaning methods primarily rely on manual labor, which is not only inefficient but also yields inconsistent cleaning results. Some manufacturers have designed glass cleaning equipment that utilizes roller brush cleaning and spray rinsing, significantly improving cleaning efficiency, but the cleaning effect is still not ideal.
[0048] The applicant of this application has conducted in-depth research on the reasons why the cleaning effect of glass cleaning equipment in related technologies is not ideal. It was found that methods such as roller brush cleaning and spray rinsing are effective at removing inorganic substances such as dust, but organic contaminants, such as oil stains or other organic dirt, sometimes adhere to the glass surface. These are difficult to completely remove through roller brush wiping and spray rinsing. Therefore, targeted methods are needed to remove organic contaminants from glass.
[0049] Based on the above, the applicant proposes the technical solution in this application embodiment. Specifically, it proposes an automatic glass cleaning device, including a roller brush cleaning section, a spray section, and a drying section, which can respectively perform roller brush cleaning, spray rinsing, and air drying on the glass. Furthermore, a corona device is installed in the feeding section of the automatic glass cleaning device. The corona device can perform corona treatment on the glass surface, removing organic contaminants such as hair and oil stains through corona discharge without generating dust. Therefore, by combining corona treatment, roller brush cleaning, and spray rinsing, both organic and inorganic contaminants can be effectively removed, thereby improving the cleaning effect.
[0050] The above is the core idea of this application. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0051] like Figure 1 , Figure 2 As shown in the embodiment of this application, an automatic glass cleaning device 1 is proposed. The automatic glass cleaning device 1 includes a feeding section 10, a roller brush cleaning section 20, a spray section 30, an air drying section 40, and a discharging section 50. The feeding section 10 includes a corona discharge device 11 and a plurality of first conveying rollers 12. The first conveying rollers 12 are used to receive and convey glass 2 to be cleaned, and the corona discharge device 11 is used to perform corona treatment on the surface of the glass 2. The roller brush cleaning section 20 is located downstream of the feeding section 10. The roller brush cleaning section 20 includes a roller brush assembly 21 and a plurality of second conveying rollers 22. The second conveying rollers 22 are used to convey the glass 2, and the roller brush assembly 21 is used to clean the glass 2. The spray section 30 is located downstream of the roller brush cleaning section 20. The spray section 30 includes a first spray head 31 and a plurality of third conveying rollers 32. The third conveying rollers 32 are used to convey the glass 2, and the spray head is used to rinse the glass 2. The drying section 40 is located downstream of the spraying section 30. The drying section 40 includes a first air knife 41 and multiple fourth conveying rollers 42. The fourth conveying rollers 42 are used to convey glass 2, and the first air knife 41 is used to dry the glass 2. The discharge section 50 includes multiple fifth conveying rollers 51, which are used to send the glass 2 out of the automatic glass cleaning equipment 1.
[0052] Specifically, the feeding section 10 is used to receive the glass 2 to be cleaned. The glass 2 to be cleaned is first sent to the feeding section 10, and the first conveying roller 12 conveys the glass 2 entering the feeding section 10 to the next working section.
[0053] The roller brush cleaning section 20 primarily cleans the glass 2 using the roller brush assembly 21. During operation, the roller brush assembly 21 wipes the surface of the glass 2, removing or loosening contaminants adhering to its surface. The second conveying roller 22 of the roller brush cleaning section 20 moves the glass 2 through the section and transports it to the next working section.
[0054] The spray section 30 primarily washes the glass 2 by spraying water. The first spray head 31 sprays pressurized water to rinse the surface of the glass 2. This rinsing process removes loosely adhering contaminants from the glass 2 surface, including dust and contaminants loosened by the brush assembly 21. The third conveyor roller 32 of the spray section 30 moves the glass 2 through the spray section 30 and transports it to the next processing section.
[0055] The drying section 40 is used to dry the glass 2. The first air knife 41 in the section provides airflow, which dries the glass 2 by passing the airflow over its surface. The fourth conveying roller 42 of the drying section 40 moves the glass 2 through the drying section 40 and transports it to the next working section.
[0056] The discharge section 50 can send the glass 2 out of the automatic glass cleaning equipment 1 through the fifth conveying roller 51.
[0057] The automatic glass cleaning equipment 1 in this embodiment includes a roller brush cleaning section 20, a spray section 30, and a drying section 40, which can respectively perform roller brush cleaning, spray rinsing, and drying treatment on the glass 2. Furthermore, a corona discharge device 11 is provided in the feeding section 10. The corona discharge device 11 can perform corona treatment on the surface of the glass 2, removing organic contaminants such as hair and oil stains without generating dust. Therefore, by combining corona treatment, roller brush cleaning, and spray rinsing, both organic and inorganic contaminants can be effectively removed, thereby improving the cleaning effect.
[0058] like Figure 1 , Figure 2 As shown, in some embodiments, the automatic glass cleaning equipment 1 further includes a first air cutting section 60, which is located downstream of the feeding section 10 and upstream of the roller brush cleaning section 20. The first air cutting section 60 includes a second air knife 61 and a plurality of sixth conveying rollers 62. The second air knife 61 is used to remove dust from the surface of the glass 2.
[0059] The first air cutting section 60 is located downstream of the feeding section 10 and upstream of the roller brush cleaning section 20. This means that the glass 2 will pass through the first air cutting section 60 before entering the roller brush cleaning section 20. The second air knife 61 can remove dust from the surface of the glass 2 by blowing. This helps to prevent the dust on the surface of the glass 2 from contaminating the water in the roller brush cleaning section 20.
[0060] like Figure 1 , Figure 2 As shown, in some embodiments, the roller brush assembly 21 includes an upper roller brush 211 and a lower roller brush 212. The upper roller brush 211 is used to clean the upper surface of the glass 2, and the lower roller brush 212 is used to clean the lower surface of the glass 2. The roller brush cleaning section 20 also includes a plurality of second spray heads 23, the water spray pressure of the second spray heads 23 being lower than the water spray pressure of the first spray head 31. A portion of the second spray heads 23 are located above the second conveying roller 22 for spraying the upper surface of the glass 2; another portion of the second spray heads 23 are located below the second conveying roller 22 for spraying the lower surface of the glass 2.
[0061] The roller brush assembly 21 includes an upper roller brush 211 and a lower roller brush 212. The upper roller brush 211 is used to clean the upper surface of the glass 2, and the lower roller brush 212 is used to clean the lower surface of the glass 2, thus ensuring that both the upper and lower surfaces of the glass 2 can be cleaned. The second spray head 23 is mainly used to wet the glass 2, which, in conjunction with the wiping of the roller brush assembly 21, improves the cleaning effect. Since the purpose of the second spray head 23 is to wet the glass 2, rather than to rinse it, the spray pressure of the second spray head 23 does not need to be set too high. Therefore, the spray pressure of the second spray head 23 is lower than that of the first spray head 31, which satisfies the need to wet the glass 2 while also reducing energy consumption.
[0062] like Figure 1 , Figure 2 As shown, in one embodiment, the number of upper roller brushes 211 is greater than the number of lower roller brushes 212, and the number of second spray heads 23 located above the second conveyor roller 22 is greater than the number of second spray heads 23 located below the second conveyor roller 22.
[0063] After glass 2 is assembled into the display device, its inner surface faces the inside of the display device, while its outer surface is exposed. Since the outer surface of glass 2 can be cleaned at any time after assembly, the required cleanliness levels for the two surfaces of glass 2 can differ during the cleaning process. In this embodiment, the upper surface of glass 2 can be used as the inner surface after assembly into the display device, and the lower surface can be used as the outer surface. In this case, the cleanliness level of the lower surface of glass 2 can be lower than that of the upper surface. Therefore, in the roller brush cleaning section 20, the number of upper roller brushes 211 is greater than the number of lower roller brushes 212, and the number of second spray heads 23 located above the second conveyor roller 22 is greater than the number of second spray heads 23 located below the second conveyor roller 22. This allows the upper surface of glass 2 to be cleaned more thoroughly, thus meeting the requirements for use as the inner surface after assembly into the display device, while also ensuring that the lower surface of glass 2 receives a basic cleaning. This also helps reduce the number of parts and save costs.
[0064] like Figure 1 , Figure 2 As shown, in one embodiment, the number of roller brush cleaning sections 20 is multiple. The automatic glass cleaning device 1 also includes multiple second air cutting sections 70, the number of which is equal to the number of roller brush cleaning sections 20. Each roller brush cleaning section 20 has a second air cutting section 70 on its downstream side. Each second air cutting section 70 includes a third air knife 71 and multiple seventh conveying rollers 72. The seventh conveying rollers 72 are used to convey glass 2, and the third air knife 71 is used to dry the glass 2.
[0065] The roller brush cleaning sections 20 are multiple, allowing the glass 2 to undergo multiple cleaning processes, thus improving the cleaning effect. Additionally, a second air-cutting section 70 is located downstream of each roller brush cleaning section 20. This second air-cutting section 70 includes a third air knife 71, which is used to dry the glass 2. This ensures that the glass 2 is promptly dried after each roller brush cleaning section 20, removing wash water from its surface. Therefore, the glass 2 achieves a certain level of cleanliness after each cleaning process in the previous roller brush cleaning section 20 before moving to the next, resulting in a continuous improvement in cleanliness with each passing roller brush cleaning section 20.
[0066] like Figure 1 , Figure 2 As shown, in some embodiments, a plurality of second conveying rollers 22 are distributed in two rows, with the second conveying rollers 22 in the upper row contacting the upper surface of the glass 2 and the second conveying rollers 22 in the lower row contacting the lower surface of the glass 2.
[0067] Multiple second conveying rollers 22 in the roller brush cleaning section 20 are distributed in two rows, one above the other. In this way, the clamping action of the upper and lower rows of second conveying rollers 22 on the glass 2 can improve the stability of the glass 2 during the conveying process. This helps to ensure that both the upper roller brush 211 and the lower roller brush 212 can effectively wipe the glass 2, thereby improving the cleaning effect.
[0068] like Figure 1 , Figure 2 As shown, in some embodiments, there are multiple first air knives 41, wherein the first air knife 41 closest to the discharge section 50 extends in a direction perpendicular to the conveying direction of the glass 2, and the angle between the extension direction of the remaining first air knives 41 and the conveying direction of the glass 2 is less than 90°.
[0069] The drying section 40 contains multiple first air knives 41. This multiple air-drying process by the first air knives 41 helps prevent water droplets from remaining on the surface of the glass 2, ensuring that the glass 2 leaves the automatic glass cleaning equipment 1 completely dry. Furthermore, the first air knife 41 closest to the discharge section 50 extends perpendicularly to the transport direction of the glass 2, while the angle between the extension directions of the remaining first air knives 41 and the transport direction of the glass 2 is less than 90°. In other words, the first few first air knives 41 that the glass 2 passes through are inclined relative to the transport direction of the glass 2, with only the last first air knife 41 perpendicular to the transport direction of the glass 2. The inclined first air knives 41 can blow water droplets from the surface of the glass 2 towards the two opposite corners of the glass 2. Thus, after multiple air-drying processes by the inclined first air knives 41, moisture may only remain at the two corners of the glass 2, resulting in a relatively small area of residual moisture on the surface of the glass 2, meaning a relatively larger dried area. With the first air knife 41, which is perpendicular to the conveying direction of glass 2 and is closest to the discharge section 50, glass 2 can be dried more thoroughly.
[0070] like Figure 1 , Figure 2 As shown, in one embodiment, the angle between the extension direction of the remaining first air knife 41 and the transmission direction of the glass 2 is greater than or equal to 45° and less than or equal to 80°.
[0071] Generally, glass 2 is a rectangular glass with a long side and a short side. When glass 2 is cleaned by automatic glass cleaning equipment 1, the length direction of glass 2 (the extension direction of the long side) is parallel to the transport direction of glass 2. The angle between the extension direction of the remaining first air knife 41 and the transport direction of glass 2 is set to be greater than or equal to 45° and less than or equal to 80°. For most rectangular glass 2, the effect of blowing water droplets towards the two opposite corners of glass 2 can be achieved, thereby achieving the effect of making the area of water vapor residue on the surface of glass 2 relatively small.
[0072] like Figure 1 , Figure 2 As shown, in some embodiments, there are multiple first spray heads 31. Some of the first spray heads 31 are located above the third conveyor roller 32 for rinsing the upper surface of the glass 2, while others are located below the third conveyor roller 32 for rinsing the lower surface of the glass 2. The number of first spray heads 31 located above the third conveyor roller 32 is greater than the number of first spray heads 31 located below the third conveyor roller 32.
[0073] There are multiple first spray heads 31, with some positioned above the third conveyor roller 32 and others below it, ensuring that both the upper and lower surfaces of the glass 2 can be rinsed. After the glass 2 is assembled into the display device, its inner surface faces the inside of the device, while its outer surface is exposed. Since the outer surface of the glass 2 can be cleaned at any time after assembly, the required cleanliness levels for the two surfaces can differ during the cleaning process. In this embodiment, the upper surface of the glass 2 can be used as the inner surface after assembly into the display device, and the lower surface can be used as the outer surface. In this case, the cleanliness level of the lower surface of the glass 2 can be lower than that of the upper surface. Therefore, in the spray section 30, the number of first spray heads 31 located above the third conveyor roller 32 is greater than the number of first spray heads 31 located below the third conveyor roller 32. This allows the upper surface of the glass 2 to be rinsed more thoroughly, achieving a higher level of cleanliness. This ensures that the upper surface of the glass 2 meets the requirements for use as an inner surface after assembly into a display device, while simultaneously ensuring that the lower surface of the glass 2 achieves a basic level of cleanliness. This also helps reduce the number of first spray heads 31, saving costs.
[0074] like Figure 1 , Figure 2 As shown, in some embodiments, the automatic glass cleaning device 1 further includes a first water supply device 80 and a second water supply device 90. The first water supply device 80 includes a first water tank 81 and a first water pump connected to the first water tank 81. The first water pump is connected to the first spray head 31 closest to the drying section 40. The second water supply device 90 includes a second water tank 91 and a second water pump connected to the second water tank 91. The second water pump is connected to the remaining first spray heads 31. The first water tank 81 is connected to a tap water source, and the second water tank 91 is configured to collect the water sprayed by the first spray heads 31 when rinsing the glass 2.
[0075] The first water tank 81 is connected to a tap water source, ensuring that the water in the first water tank 81 is clean tap water. Correspondingly, the water sprayed from the first spray head 31 closest to the drying section 40 is the cleanest tap water. The second water tank 91 is configured to recycle the water sprayed by the first spray head 31 when rinsing the glass 2. In other words, the water sprayed by the remaining first spray heads 31 is recycled multiple times. This configuration allows for repeated use of the spray water, thus saving water. Furthermore, using the cleanest tap water in the final spray helps ensure the cleaning effect when the glass 2 leaves the spray section 30.
[0076] like Figure 1 , Figure 2 As shown, in some embodiments, the automatic glass cleaning equipment 1 further includes a housing 100, with the roller brush assembly 21, the second conveying roller 22, the first spray head 31, the third conveying roller 32, the first air knife 41, and the fourth conveying roller 42 all located inside the housing 100. This ensures that the roller brush cleaning, spray rinsing, and drying processes of the glass 2 are all carried out in a dust-free environment, thereby preventing secondary contamination of the glass 2 during the cleaning process.
[0077] In one embodiment, the feeding section 10, the first air-cutting section 60, the roller brush cleaning section 20, the second air-cutting section 70, the spraying section 30, the air-drying section 40, and the discharging section 50, each of the above-mentioned operating sections, can be configured as a functional module, and the functional modules are connected in a detachable manner. This facilitates the transportation of the automatic glass cleaning equipment 1.
[0078] Furthermore, the housing 100 can be assembled from multiple sections. Each of the first air-cutting section 60, the roller brush cleaning section 20, the second air-cutting section 70, the spraying section 30, and the drying section 40 can correspond to a section of the housing 100, and adjacent sections can be connected in a disassembly manner. In this way, when the various working sections are connected in sequence, the various sections can also be assembled to form the housing 100.
[0079] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
