Description

Technical Field

[0001] This invention relates to the field of roll coating technology, and in particular to a roll coating equipment and roll coating control method for a biomimetic antireflective film on the surface of photovoltaic glass. Background Technology

[0002] Photovoltaic anti-reflective coated glass is a special type of photovoltaic glass material. It is generally made by coating an anti-reflective film onto the surface of a photovoltaic glass substrate using a roller coating process. Then, it undergoes high-temperature tempering and sintering to improve the adhesion between the film and the glass, enhance the strength of the glass, and increase the output power of the photovoltaic module. It is commonly used as cover glass on the surface of solar modules.

[0003] Currently, photovoltaic anti-reflective glass is mainly produced by coating anti-reflective films onto glass surfaces using roller coating equipment. Before using the equipment, all raw materials, such as photovoltaic glass and coating solution, need to be prepared. Then, the cleaned photovoltaic glass is placed on a conveyor belt. The photovoltaic glass enters the equipment via the conveyor belt and reaches the coating position after a certain transmission time. During the movement of the photovoltaic glass, the coating solution is evenly roller-coated onto the surface of the photovoltaic glass. By controlling the pressure and speed of the coating roller, the uniformity and thickness of the coating are adjusted. Finally, the coated photovoltaic glass is output from the conveyor belt and then dried.

[0004] However, in existing roller coating equipment, if the position of the coating roller is not properly adjusted during the photovoltaic glass coating process, the photovoltaic glass can easily rub against the coating roller during coating, causing relative misalignment with the conveyor belt. This results in a small amount of coating liquid accumulating on the photovoltaic glass, which can easily lead to uneven roller coating, resulting in inconsistent thickness and uneven coating coverage, thus affecting the final conversion efficiency of the solar panel. In order to avoid this phenomenon, existing technologies select different coating pressures according to different thicknesses of photovoltaic glass to reduce the occurrence of uneven coating. However, simply adjusting the pressure is still difficult to completely prevent the coating from accumulating in small amounts when the photovoltaic glass stops.

[0005] Therefore, existing technologies still need further improvement and development. Summary of the Invention

[0067] A roll coating control method for a roll coating apparatus for a biomimetic antireflective film on a photovoltaic glass surface as described in any of the preceding claims, comprising the steps of:

[0068] When applying coating liquid to photovoltaic glass, first adjust the position of the coating roller according to the thickness of the photovoltaic glass. First, hold the manual turntable and then rotate the manual turntable to drive the drive shaft to rotate. The rotation of the drive shaft drives the first gear to rotate. Through the cooperation of the first gear and the first rack, the first rack drives the moving frame to move inside the roller coating frame. After the moving frame moves the coating roller to the set position, the position of the manual turntable is fixed.

[0069] Turn on the second motor to drive the coating roller to rotate. At the same time, start the delivery pump. The delivery pump draws the coating solution from the storage tank through the feed pipe and then delivers the coating solution to the feeding pipe through the delivery pipe. When the feeding pipe is full of coating solution, start the feeding nozzle. The feeding nozzle sprays the coating solution evenly between the feeding roller and the coating roller. Through the cooperation of the feeding roller and the leveling roller, the coating solution is more evenly adhered to the coating roller, and the photovoltaic glass is coated with anti-reflection coating.

[0070] The roller coating control method for the roller coating equipment used for biomimetic antireflective films on photovoltaic glass surfaces further includes the following step before roller coating:

[0071] Place the coating solution into the storage tank and adjust the thickness of the anti-reflective film according to the design requirements: Hold the lever, turn the lever to drive the adjustment shaft to rotate, and the rotation of the adjustment shaft will drive the second gear to rotate.

[0072] The second gear drives the fan-shaped frame to swing along the end of the fan-shaped frame via the arc rack. The swing of the fan-shaped frame drives the moving block to move inside the moving frame. The movement of the moving block drives the feeding roller and the leveling roller to move simultaneously. Adjust the position of the feeding roller and the leveling roller, and then adjust the position of the coating roller.

[0073] The working principle and beneficial effects of this invention are as follows:

[0074] 1) In this invention, turning the lever drives the adjusting shaft to rotate, which in turn drives the second gear to rotate. The second gear drives the fan-shaped frame to swing along the end of the fan-shaped frame via an arc rack. The swing of the fan-shaped frame drives the moving block to move inside the moving frame. The movement of the moving block drives the feeding roller and the leveling roller to move simultaneously. This allows for convenient adjustment of the positions of the feeding roller and the leveling roller, improving the speed of adjusting the anti-reflective film thickness. Furthermore, since the moving speeds of the leveling roller and the feeding roller are the same, the thickness of the roller coating can be calculated more accurately.

[0075] 2) In this invention, the third motor drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the nut to move in the opposite direction. The nut drives the housing to move inside the auxiliary frame. As the housing moves, the housing drives the active helical gear to move along the power shaft. When the housing moves to the set position, the third motor is turned off, fixing the position of the housing. At this time, the roller is in contact with the side of the photovoltaic glass. The power shaft drives the third gear to rotate through the cooperation of the active and driven helical gears. The third gear drives the roller to rotate through the cooperation of the fourth gear. Thus, the rotation of the roller synchronously drives the photovoltaic glass to move on the conveyor belt, improving the stability of the photovoltaic glass and avoiding the phenomenon of jamming during the roll coating process.

[0076] 3) In this invention, the rotation of the power shaft drives the active helical gear to rotate, which in turn drives the driven helical gear to rotate. The driven helical gear then drives the third gear to rotate, which in turn drives the fourth gear to rotate. This fourth gear then drives the roller to rotate. As the photovoltaic glass moves along the conveyor belt, the roller clamps both sides of the photovoltaic glass by the movement of the housing, moving the photovoltaic glass synchronously with the conveyor belt. To ensure a tighter contact between the roller and the photovoltaic glass, the housing needs to be moved further towards the photovoltaic glass. During this movement, the fourth gear drives the slider to slide inside the arc frame, while the sleeve slides outside the slider. The spring is stretched, and the spring force firmly holds the roller against the side of the photovoltaic glass, improving stability during movement.

[0077] 4) In this invention, by adjusting the cooperation of the component and the feeding component, the thickness of the antireflective film can be easily adjusted according to requirements when the photovoltaic glass is roller coated. The setting of the leveling roller can also make the coating liquid on the coating roller adhere more evenly. By cooperating with the driving component and the moving component, during the process of the conveyor belt pushing the photovoltaic glass to move and roller coating, the relative misalignment between the photovoltaic glass and the conveyor belt caused by the large friction between the coating roller and the photovoltaic glass is avoided, which would cause a small amount of coating liquid to accumulate on the photovoltaic glass, resulting in uneven local thickness of the antireflective film and uneven coating coverage.

[0091] This invention provides a roller coating device and control method for biomimetic antireflective films on photovoltaic glass surfaces. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0092] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0093] In existing roller coating equipment, if the position of the coating roller is not properly adjusted during the photovoltaic glass coating process, the photovoltaic glass can easily rub against the coating roller during coating, causing relative misalignment with the conveyor belt. This results in a small amount of coating liquid accumulating on the photovoltaic glass, which can easily lead to uneven roller coating, resulting in inconsistent thickness and uneven coating coverage, thus affecting the final conversion efficiency of the solar panel. In order to avoid this phenomenon, existing technologies select different coating pressures according to different thicknesses of photovoltaic glass to reduce the occurrence of uneven coating. However, simply adjusting the pressure is still difficult to completely prevent the coating from accumulating in small amounts when the photovoltaic glass stops.

[0094] To address the problems existing in the prior art, this invention designs a roller coating device for biomimetic antireflective films on the surface of photovoltaic glass, which provides more uniform coating and prevents friction between the photovoltaic glass and the conveyor belt during movement.

[0095] like Figures 1 to 12 As shown in the figure, an embodiment of the present invention provides a roll coating equipment for a biomimetic antireflective film on a photovoltaic glass surface, comprising:

[0096] The components include a fixed frame 100, a transport unit 200, a roller coating unit 300, and an auxiliary unit 400, such as... Figure 1 As shown;

[0097] The transport unit 200 is installed inside the fixed frame 100 and is used to move the photovoltaic glass, such as... Figure 1 , Figure 2 and Figure 3As shown, the transport unit 200 includes a transport roller 4, an intermediate roller 5, a transport belt 6, a first motor 7, and a support roller 8. The transport roller 4 is rotatably mounted at the end of the fixed frame 100. Multiple intermediate rollers 5 are rotatably mounted at equal intervals inside the fixed frame 100. The transport belt 6 connects the transport roller 4 and the intermediate rollers 5. The first motor 7 is fixedly mounted on the fixed frame 100, and the output end of the first motor 7 is fixedly connected to the transport roller 4. The support roller 8 is rotatably mounted inside the fixed frame 100. The support roller 8 is located inside the transport belt 6 and is located at the lower part of the roller coating frame 2.

[0098] Specifically, such as Figure 1 and Figure 3 As shown, when applying an anti-reflective coating to photovoltaic glass, the photovoltaic glass must first be moved to the coating position. The first motor 7 is then started, driving the transport roller 4 to rotate, which in turn drives the transport belt 6 to rotate. Once the photovoltaic glass reaches the coating position, the coating unit 300 is started to coat the photovoltaic glass. Simultaneously, the support roller 8 ensures a consistent distance between the coating unit 300 and the photovoltaic glass during the coating process. During coating, the auxiliary unit 400 moves the photovoltaic glass and the transport belt 6 synchronously, thus preventing relative misalignment between the photovoltaic glass and the transport belt 6 during coating and reducing uneven coating.

[0099] like Figure 1 As shown, the roll coating unit 300 is mounted on the fixed frame 100 and is used to roll coat an anti-reflective film onto photovoltaic glass, wherein, as... Figure 2 , Figure 4 and Figure 5 As shown, the roller coating unit 300 includes a roller coating frame 2, a roller coating assembly, an adjustment assembly, and a feeding assembly. The roller coating frame 2 is fixedly mounted on the upper part of the fixed frame 100, and the roller coating assembly is installed inside the roller coating frame 2. Figure 5 and Figure 6As shown, the roller coating assembly includes a movable frame 9, a coating roller 10, a first rack 11, a drive shaft 12, a first gear 13, a manual turntable 14, and a second motor 15. The movable frame 9 is slidably mounted inside the roller coating frame 2. The coating roller 10 is rotatably mounted inside the movable frame 9. The first rack 11 is fixedly mounted at the end of the movable frame 9. The drive shaft 12 is rotatably mounted inside the roller coating frame 2. The first gear 13 is fixedly mounted at the end of the drive shaft 12 and meshes with the first rack 11. The manual turntable 14 is rotatably mounted on the roller coating frame 2 and is fixedly connected to the drive shaft 12. The second motor 15 is fixedly mounted on the movable frame 9, and the output end of the second motor 15 is fixedly connected to the coating roller 10. The second motor 15 is slidably engaged with the roller coating frame 2.

[0100] Specifically, such as Figure 5 and Figure 6 As shown, when applying coating liquid to photovoltaic glass, the position of the coating roller 10 needs to be adjusted according to the thickness of the photovoltaic glass. First, hold the manual turntable 14 and then rotate the manual turntable 14 to drive the transmission shaft 12 to rotate. The rotation of the transmission shaft 12 drives the first gear 13 to rotate. Through the cooperation of the first gear 13 and the first rack 11, the first rack 11 drives the moving frame 9 to move inside the roller coating frame 2. After the moving frame 9 drives the coating roller 10 to the set position, the position of the manual turntable 14 is fixed. Then, the second motor 15 is turned on, and the second motor 15 drives the coating roller 10 to rotate. At this time, by coordinating the adjustment component and the feeding component, the coating liquid is evenly distributed on the coating roller 10, and the photovoltaic glass can be coated with anti-reflection coating.

[0101] In a further embodiment, the adjusting component is installed inside the roll coating assembly and is used to control the thickness of the antireflective film rolled out, such as... Figure 6 and Figure 7As shown, the adjustment assembly includes a sector frame 16, an arc-shaped rack 17, an adjustment shaft 18, a second gear 19, a paddle 20, a feeding roller 21, and a leveling roller 23. Two sector frames 16 are provided, with their ends rotatably mounted inside the movable frame 9. The ends of the sector frames 16 are located above the axis of the coating roller 10. Arc-shaped racks 17 are fixedly mounted on the outside of the two sector frames 16. The adjustment shaft 18 is rotatably mounted inside the movable frame 9. Two second gears 19 are provided, with the two second gears 19 fixedly mounted on the adjustment shaft 18. At both ends, the second gear 19 meshes with the arc-shaped rack 17. The paddle 20 is fixedly installed at one end of the adjusting shaft 18. The feeding roller 21 is slidably installed between the two sector frames 16 through the moving block 22. The feeding roller 21 and the moving block 22 are rotatably engaged. The leveling roller 23 is slidably installed between the two sector frames 16 through the moving block 22. The leveling roller 23 is located below the feeding roller 21. The leveling roller 23 and the moving block 22 are rotatably engaged. The moving block 22 is slidably engaged with the moving frame 9 and slidably connected to the inner wall of the sector frame 16.

[0102] In this embodiment of the invention, specifically, when roll-coating photovoltaic glass, the thickness of the anti-reflective film needs to be adjusted according to design requirements, such as... Figure 6 and Figure 7 As shown, first, hold the lever 20 and turn it to rotate the adjusting shaft 18. The rotation of the adjusting shaft 18 drives the second gear 19 to rotate. The rotating second gear 19 drives the fan-shaped frame 16 to swing along the end of the fan-shaped frame 16 through the arc rack 17. The swing of the fan-shaped frame 16 drives the moving block 22 to move inside the moving frame 9. The movement of the moving block 22 drives the feeding roller 21 and the leveling roller 23 to move simultaneously. This makes it easy to adjust the position of the feeding roller 21 and the leveling roller 23, improving the speed of adjusting the anti-reflective film thickness. Furthermore, the moving speed of the leveling roller 23 and the feeding roller 21 is the same, which allows for more accurate calculation of the coating thickness. After adjustment, the photovoltaic glass can be coated.

[0103] As can be seen from the above, in this embodiment of the invention, turning the lever drives the adjusting shaft to rotate, which in turn drives the second gear to rotate. The second gear drives the fan-shaped frame to swing along the end of the fan-shaped frame via an arc rack. Through the swing of the fan-shaped frame, the fan-shaped frame drives the moving block to move inside the moving frame. The movement of the moving block drives the feeding roller and the leveling roller to move simultaneously. This allows for convenient adjustment of the positions of the feeding roller and the leveling roller, improving the speed of adjusting the anti-reflective film thickness. Furthermore, since the moving speeds of the leveling roller and the feeding roller are the same, the thickness of the roller coating can be calculated more accurately.

[0104] In this embodiment of the invention, the feeding assembly is mounted on the fixed frame 100 and is used to deliver the coating liquid into the roller coating assembly, such as... Figure 2 , Figure 11 and Figure 12 As shown, the feeding assembly includes a feeding pipe 24, a feeding nozzle 25, a storage tank 26, a conveying pump 27, a feed pipe 28, and a conveying pipe 29, wherein, as... Figure 5 As shown, the feeding pipe 24 is fixedly installed inside the mobile frame 9, and multiple feeding nozzles 25 are connected at equal intervals at the bottom of the feeding pipe 24, such as... Figure 12 As shown, the feeding nozzle 25 is located between the feeding roller 21 and the coating roller 10, as... Figure 2 As shown, the storage tank 26 is fixedly installed on the fixed frame 100, the conveying pump 27 is fixedly installed on the storage tank 26, the feed pipe 28 is connected between the feed inlet of the conveying pump 27 and the storage tank 26, and the conveying pipe 29 is connected between the discharge outlet of the conveying pump 27 and the feeding pipe 24.

[0105] Specifically, such as Figure 2 , Figure 6 , Figure 11 and Figure 12 As shown, when roller coating an antireflective film, the coating solution needs to be sprayed between the feed roller 21 and the coating roller 10. First, the coating solution is placed inside the storage tank 26, and then the delivery pump 27 is started. The delivery pump 27 extracts the coating solution from the storage tank 26 through the feed pipe 28, and then delivers the coating solution to the feeding pipe 24 through the delivery pipe 29. When the feeding pipe 24 is full of coating solution, the feeding nozzle 25 is started, and the coating solution is evenly sprayed between the feed roller 21 and the coating roller 10 through the feeding nozzle 25. Through the cooperation of the feed roller 21 and the leveling roller 23, the coating solution is more evenly adhered to the coating roller 10, thereby improving the uniformity of coating.

[0106] As can be seen from the above, in this embodiment of the invention, by adjusting the cooperation of the adjustment component and the feeding component, the thickness of the antireflective film can be easily adjusted according to requirements when the photovoltaic glass is roller coated. The setting of the leveling roller can also make the coating liquid on the coating roller adhere more evenly. By cooperating with the driving component and the moving component, during the process of the conveyor belt pushing the photovoltaic glass to move and roller coating, the relative misalignment between the photovoltaic glass and the conveyor belt caused by the large friction between the coating roller and the photovoltaic glass is avoided, which would cause a small amount of coating liquid to accumulate on the photovoltaic glass, resulting in uneven local thickness of the antireflective film and uneven coating coverage.

[0107] In a further embodiment, the auxiliary unit is installed inside the roller coating frame 2 to assist the photovoltaic glass in moving at a uniform speed during the roller coating of the antireflective film, wherein, as shown... Figure 4As shown, the auxiliary unit includes an auxiliary frame 3, a moving component, and a driving component. Two auxiliary frames 3 are provided, and both auxiliary frames 3 are fixedly installed inside the roller coating frame 2. Moving components are installed inside both auxiliary frames 3, such as... Figure 8 As shown, the moving assembly includes a bidirectional screw 30, a third motor 31, a nut 32, a housing 33, a drive helical gear 34, and a power shaft 35. The bidirectional screw 30 is rotatably mounted inside both auxiliary frames 3. Figure 1 As shown, the third motor 31 is fixedly mounted on the fixed frame 100, as... Figure 8 As shown, the output end of the third motor 31 is fixedly connected to the bidirectional screw 30. Nuts 32 are threaded onto both ends of the bidirectional screw 30. Housings 33 are fixedly installed at the bottom of both nuts 32. The housings 33 are slidably fitted with the auxiliary frame 3. Active helical gears 34 are rotatably installed on the inner sidewalls of both housings 33. A power shaft 35 is slidably installed between the two active helical gears 34. The power shaft 35 is rotatably installed inside the roller coating frame 2. The power shaft 35 is slidably fitted with the housing 33.

[0108] Specifically, such as Figure 8 and Figure 9 As shown, to ensure the stability of the photovoltaic glass during the roll coating process, when the photovoltaic glass enters the roll coating frame 2, the third motor 31 is started. The third motor 31 drives the bidirectional screw 30 to rotate. The rotation of the bidirectional screw 30 drives the nut 32 to move in the opposite direction. The nut 32 drives the housing 33 to move inside the auxiliary frame 3. As the housing 33 moves, it drives the active helical gear 34 to move along the power shaft 35. When the housing 33 moves to the set position, the third motor 31 is turned off, fixing the position of the housing 33. At this time, the roller 41 is in contact with the side of the photovoltaic glass. Through the rotation of the power shaft 35, the power shaft 35 drives the third gear 37 to rotate through the cooperation of the active helical gear 34 and the driven helical gear 36. The third gear 37 drives the roller 41 to rotate through the cooperation of the fourth gear 40. Thus, the rotation of the roller 41 synchronously drives the photovoltaic glass to move on the conveyor belt 6, improving the stability of the photovoltaic glass and avoiding the phenomenon of the photovoltaic glass getting stuck during roll coating.

[0109] In embodiments of the present invention, such as Figure 8 , Figure 9 and Figure 10As shown, each of the two moving components has a drive assembly installed at its lower part to drive the photovoltaic glass to move at a constant speed with the transport unit. The drive assembly includes a driven helical gear 36, a third gear 37, an arc frame 38, a slider 39, a fourth gear 40, a roller 41, a spring 42, and a power unit. A driven helical gear 36 is rotatably mounted on the inner bottom wall of each of the two housings 33. The driven helical gear 36 meshes with the driving helical gear 34. A third gear 37 is fixedly mounted on the bottom of each of the two driven helical gears 36. An arc frame 38 is fixedly mounted at corresponding positions on the two housings 33. A slider 39 is slidably mounted at both ends inside the arc frame 38. A fourth gear 40 is rotatably mounted on the bottom of each of the two sliders 39. The fourth gear 40 meshes with the third gear 37. A roller 41 is fixedly mounted on the bottom of each of the two fourth gears 40. A spring 42 is fixedly mounted between the two sliders 39 through a sleeve 43. The sleeve 43 rotates with the slider 39. The power unit is mounted on a power shaft 35 to drive the roller 41 to rotate.

[0110] Specifically, such as Figure 8 , Figure 9 and Figure 10 As shown, the power unit drives the power shaft 35 to rotate, which in turn drives the driving helical gear 34 to rotate. The driving helical gear 34 then drives the driven helical gear 36 to rotate, which in turn drives the third gear 37 to rotate. The third gear 37 then drives the fourth gear 40 to rotate, which in turn drives the roller 41 to rotate. During the movement of the photovoltaic glass along the conveyor belt 6, the roller 41 clamps both sides of the photovoltaic glass via the movement of the housing 33, moving synchronously with the conveyor belt 6. Due to the power unit, the rotational speed of the roller 41 is the same as the movement speed of the conveyor belt 6. When the roller 41 initially contacts the photovoltaic glass, to ensure a tighter contact, the housing 33 needs to be moved further towards the photovoltaic glass. Figure 8 and Figure 10 As shown, during the movement, the fourth gear 40 drives the slider 39 to slide inside the arc frame 38, while the sleeve 43 slides outside the slider 39. The spring 42 is stretched, and the roller 41 is firmly attached to the side of the photovoltaic glass by the elastic force of the spring 42 and the inner guide of the arc frame 38, which improves the stability during the movement.

[0111] In embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 9As shown, the power unit includes a driven sprocket 44, a first chain 45, a driving sprocket 46, a driven sprocket 47, and a second chain 48. A driven sprocket 44 is fixedly mounted at one end of each of the two power shafts 35, and the first chain 45 meshes between the two driven sprockets 44. Figure 3 As shown, the drive sprocket 46 is fixedly installed at the output end of the first motor 7; as Figure 8 As shown, the driven sprocket 47 is fixedly mounted on the other end of one of the drive shafts 35, as... Figure 1 As shown, a second chain 48 is meshed between the driving sprocket 46 and the driven sprocket 47.

[0112] Specifically, such as Figure 1 As shown, during the movement of the photovoltaic glass, when the first motor 7 is started and the conveyor belt 6 is moved, the first motor 7 drives the drive sprocket 46 to rotate. The drive sprocket 46 drives the driven sprocket 47 to rotate via the second chain 48, thereby driving one of the drive shafts 35 to rotate. Figure 9 As shown, by setting the passive sprocket 44, when one of the drive shafts 35 rotates, it drives the passive sprocket 44 to rotate. By setting the first chain 45, the first motor 7 can drive both drive shafts 35 to rotate simultaneously.

[0113] In summary, when applying antireflective coating to photovoltaic glass, the coating solution is first placed inside the storage tank 26 before coating. Then, the thickness of the antireflective coating is adjusted according to the design requirements. First, hold the lever 20 and turn it to rotate the adjusting shaft 18. The rotation of the adjusting shaft 18 drives the second gear 19 to rotate. The second gear 19 drives the fan-shaped frame 16 to swing along the end of the fan-shaped frame 16 through the arc rack 17. The swing of the fan-shaped frame 16 drives the moving block 22 to move inside the moving frame 9. The movement of the moving block 22 drives the feeding roller 21 and the leveling roller 23 to move simultaneously. This allows for convenient adjustment of the positions of the feeding roller 21 and the leveling roller 23, improving the speed of adjusting the antireflective coating thickness. Furthermore, the moving speeds of the leveling roller 23 and the feeding roller 21 are the same, allowing for more accurate calculation of the coating thickness. After adjustment, the position of the coating roller 10 can be adjusted.

[0114] When applying the coating solution to photovoltaic glass, first adjust the position of the coating roller 10 according to the thickness of the photovoltaic glass, such as... Figure 4 and Figure 5As shown, first hold the manual turntable 14, then rotate the manual turntable 14 to drive the transmission shaft 12 to rotate. The rotation of the transmission shaft 12 drives the first gear 13 to rotate. Through the cooperation of the first gear 13 and the first rack 11, the first rack 11 drives the moving frame 9 to move inside the roller coating frame 2. After the moving frame 9 drives the coating roller 10 to the set position, the position of the manual turntable 14 is fixed. Then, turn on the second motor 15, which drives the coating roller 10 to rotate. At this time, the conveyor is started. Pump 27, the delivery pump 27, draws the coating liquid from the storage tank 26 through the feed pipe 28, and then delivers the coating liquid to the feeding pipe 24 through the delivery pipe 29. When the feeding pipe 24 is full of coating liquid, the feeding nozzle 25 is activated, and the coating liquid is evenly sprayed between the feeding roller 21 and the coating roller 10 through the feeding nozzle 25. Through the cooperation of the feeding roller 21 and the uniform roller 23, the coating liquid is more evenly attached to the coating roller 10, thereby improving the uniformity of coating, so as to perform roll coating anti-reflection coating on photovoltaic glass.

[0115] When applying an anti-reflective coating to photovoltaic glass, the photovoltaic glass must be moved to the coating position. First, the first motor 7 is started, which drives the transport roller 4 to rotate. The rotation of the transport roller 4 drives the transport belt to rotate. After the photovoltaic glass enters the coating frame 2, the third motor 31 is started. The third motor 31 drives the bidirectional screw 30 to rotate. The rotation of the bidirectional screw 30 drives the nut 32 to move in the opposite direction. The nut 32 drives the housing 33 to move inside the auxiliary frame 3. As the housing 33 moves, it drives the drive helical gear 34 along the power shaft 35. When the housing 33 moves to the set position and the roller 41 initially contacts the photovoltaic glass, in order to make the roller 41 contact the photovoltaic glass more tightly, the housing 33 needs to be moved further towards the photovoltaic glass. During the movement, the fourth gear 40 drives the slider 39 to slide inside the arc frame 38. At this time, the sleeve 43 slides outside the slider 39, and the spring 42 is stretched. At this time, the elastic force of the spring 42 firmly attaches the roller 41 to the side of the photovoltaic glass, improving the stability during the movement. Then the third motor 31 is turned off to fix the position of the housing 33.

[0116] During the movement of the conveyor belt 6 driven by the first motor 7, the first motor 7 drives the drive sprocket 46 to rotate. The drive sprocket 46 drives the driven chain to rotate via the second chain 48, thereby driving one of the drive shafts 35 to rotate. Through the arrangement of the driven sprocket 44, while one drive shaft 35 rotates, it simultaneously drives the driven sprocket 44 to rotate. With the arrangement of the first chain 45, the first motor 7 can simultaneously drive two drive shafts 35 to rotate. The rotation of the drive shafts 35 drives the drive helical gear 34 to rotate, which in turn drives the driven helical gear 36 to rotate. The rotation of the driven helical gear 36 drives the third gear 37 to rotate. The rotation of wheel 37 drives the fourth gear 40 to rotate, which in turn drives the roller 41 to rotate. As the photovoltaic glass moves along the conveyor belt 6, the roller 41 holds both sides of the photovoltaic glass and moves synchronously with the conveyor belt 6. The rotation speed of the roller 41 is the same as the movement speed of the conveyor belt 6, which improves the stability of the photovoltaic glass during movement and avoids the photovoltaic glass from getting stuck during roller coating. It also prevents the photovoltaic glass from shifting relative to the conveyor belt 6 during coating, reducing the occurrence of uneven coating. At the same time, the setting of the support roller 8 ensures that the distance between the roller coating unit 300 and the photovoltaic glass is consistent during the roller coating process.

[0117] The working principle and beneficial effects of this invention are as follows:

[0118] 1) In this invention, turning the lever drives the adjusting shaft to rotate, which in turn drives the second gear to rotate. The second gear drives the fan-shaped frame to swing along the end of the fan-shaped frame via an arc rack. The swing of the fan-shaped frame drives the moving block to move inside the moving frame. The movement of the moving block drives the feeding roller and the leveling roller to move simultaneously. This allows for convenient adjustment of the positions of the feeding roller and the leveling roller, improving the speed of adjusting the anti-reflective film thickness. Furthermore, since the moving speeds of the leveling roller and the feeding roller are the same, the thickness of the roller coating can be calculated more accurately.

[0119] 2) In this invention, the third motor drives the bidirectional screw to rotate. The rotation of the bidirectional screw causes the nut to move in the opposite direction, which in turn moves the housing within the auxiliary frame. As the housing moves, it drives the active helical gear to move along the power shaft. When the housing reaches the set position, the third motor is turned off, fixing the housing in place. At this point, the roller is in contact with the side of the photovoltaic glass. The power shaft, through the engagement of the active and driven helical gears, drives the third gear to rotate. The third gear, through the engagement of the fourth gear, drives the roller to rotate. Thus, the rotation of the roller synchronously moves the photovoltaic glass on the conveyor belt, improving the stability of the photovoltaic glass and preventing jamming during the roll coating process.

[0120] 3) In this invention, the rotation of the power shaft drives the active helical gear to rotate, which in turn drives the driven helical gear to rotate. The driven helical gear then drives the third gear to rotate, which in turn drives the fourth gear to rotate. This fourth gear then drives the roller to rotate. As the photovoltaic glass moves along the conveyor belt, the roller clamps both sides of the photovoltaic glass by the movement of the housing, moving the photovoltaic glass synchronously with the conveyor belt. To ensure a tighter contact between the roller and the photovoltaic glass, the housing needs to be moved further towards the photovoltaic glass. During this movement, the fourth gear drives the slider to slide inside the arc frame, while the sleeve slides outside the slider. The spring is stretched, and the spring force firmly holds the roller against the side of the photovoltaic glass, improving stability during movement.

[0121] 4) In this invention, by adjusting the cooperation of the component and the feeding component, the thickness of the antireflective film can be easily adjusted according to requirements when the photovoltaic glass is roller coated. The setting of the leveling roller can also make the coating liquid on the coating roller adhere more evenly. By cooperating with the driving component and the moving component, during the process of the conveyor belt pushing the photovoltaic glass to move and roller coating, the relative misalignment between the photovoltaic glass and the conveyor belt caused by the large friction between the coating roller and the photovoltaic glass is avoided, which would cause a small amount of coating liquid to accumulate on the photovoltaic glass, resulting in uneven local thickness of the antireflective film and uneven coating coverage.

[0122] It should be understood that the application of the present invention is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
