Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, and in particular to a lamination tooling for a curved double-glass photovoltaic assembly. Background Art

[0002] Combination Figure 1 and Figure 2 As shown, the curved double-glass photovoltaic module 300 includes a front cover plate 310 , a rear cover plate 320 and a power generation element 340 . The power generation element 340 is located in front of the front cover plate 310 and the rear cover plate 320 . The front cover plate 310 and the rear cover plate 320 are bonded and fixed by a packaging film 330 .

[0003] During the bonding process of the front cover plate 310 and the rear cover plate 320 , bubbles and empty glue are easily formed in the packaging film 330 between the front cover plate 310 and the rear cover plate 320 , resulting in a high defective rate of the product. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] In view of this, the utility model proposes a laminating tool for a curved double-glass photovoltaic module, comprising: a shaping tool for pressing onto the curved double-glass photovoltaic module to be laminated; a locking tool for clamping the curved double-glass photovoltaic module, and the shaping tool and the locking tool are used to cooperate with different positions on the curved double-glass photovoltaic module.

[0006] During the assembly process of the curved double-glass photovoltaic module, the front cover, rear cover, packaging film and power generation elements need to be stacked. The packaging film is used to bond the front cover and the rear cover. In order to ensure that the front cover and the rear cover fit tightly, the front cover needs to apply pressure to the packaging film. If the packaging film is pressed only by the weight of the front cover itself, it is difficult to improve the tightness of the fit between the front cover and the rear cover due to the insufficient weight of the front cover. In the utility model, a shaping tool is used to press on the curved double-glass photovoltaic module. The shaping tool applies pressure to the front cover, thereby increasing the bonding force between the front cover and the rear cover, so that the front cover and the rear cover can fit tightly. During the pressing process, the shaping tool completely relies on its own gravity, so that the front cover is evenly stressed, ensuring that the front cover and the rear cover can be in good contact.

[0007] When the front cover is pressed together, the locking fixture can be used to clamp the curved double-glass photovoltaic module to ensure good contact between the front cover and the rear cover. This can effectively reduce defective outputs such as empty glue, bubbles, and glass misalignment during the lamination process, and improve the product qualification rate.

[0008] The shaping tooling and the locking tooling are coordinated with different positions on the curved double-glass photovoltaic module, so as to avoid interference between the shaping tooling and the locking tooling, and ensure the stability of the use of the shaping tooling and the locking tooling.

[0009] In addition, the lamination tooling for the curved double-glass photovoltaic module in the above technical solution provided by the utility model may also have the following additional technical features:

[0010] In some technical solutions, optionally, a locking notch is provided on the shaping tool, and a part of the locking tool extends into the locking notch so that the shaping tool avoids the locking tool.

[0011] A locking notch is formed on the shaping tooling. When the locking tooling is installed on the curved double-glass photovoltaic module, a part of the locking tooling is located in the locking notch. The locking notch can avoid the locking tooling to prevent the shaping tooling and the locking tooling from interfering with each other during use.

[0012] The larger the contact area between the shaping tool and the front cover, the more uniform the force on the front cover. Therefore, when the length of the shaping tool is equal to the length of the front cover, and the width of the shaping tool is equal to the width of the front cover, the shaping tool can completely cover the front cover, improving the uniformity of the force on the front cover. In order to avoid interference between the shaping tool and the installation of the locking tool, a locking notch is set on the side of the shaping tool so that the locking tool can clamp the front cover and the rear cover, ensuring the stability of the locking tool clamping the curved double-glass photovoltaic module.

[0013] In a possible application, when the locking tool clamps the curved double-glass photovoltaic module, the shaping tool can be removed, and the curved double-glass photovoltaic module is clamped and fixed only by the locking tool. Due to the presence of the locking notch, when the shaping tool is removed, the locking tool will not interfere with the removal process of the shaping tool.

[0014] In some technical solutions, optionally, there are multiple locking notches, and the multiple locking notches are spaced apart along the length direction of the shaping tooling and / or the width direction of the shaping tooling. There are multiple locking toolings, and the multiple locking toolings correspond one-to-one to the multiple locking notches.

[0015] In order to ensure that the front cover can be evenly stressed, it is necessary to use locking fixtures to clamp the front cover on both sides along the length direction to avoid the front cover from tilting on one side and ensure the tight contact between the front cover and the rear cover. Similarly, the locking fixtures can also be used to clamp the front cover on both sides along the width direction. Accordingly, in order to ensure that the locking fixture and the front cover can be stably matched, it is necessary to set locking notches on both sides of the shaping fixture along the length direction, or to set locking notches on both sides of the shaping fixture along the width direction. Of course, in order to further ensure the uniformity of the force on the front cover, locking notches can also be set on both sides of the shaping fixture along the length direction and both sides of the width direction, so that the locking fixture can clamp the curved double-glass photovoltaic module along both sides of the length direction and both sides of the width direction of the front cover.

[0016] Multiple locking notches can be arranged at intervals along the length direction and / or width direction of the shaping tooling, so that multiple locking tooling can be used to clamp the curved double-glass photovoltaic module at the same time to avoid displacement between the front cover and the rear cover.

[0017] In some technical schemes, optionally, there are multiple locking toolings, and the multiple locking toolings include: a first locking tooling and a second locking tooling; wherein, the first locking tooling and the second locking tooling are respectively located on both sides of the shaping tooling along the length direction, the length of the shaping tooling is L1, the distance between the first locking tooling and the second locking tooling is L2, and L1 and L2 satisfy, L1≤L2; or the first locking tooling and the second locking tooling are respectively located on both sides of the shaping tooling along the width direction, the width of the shaping tooling is W1, the distance between the first locking tooling and the second locking tooling is W2, and W1 and W2 satisfy, W1≤W2.

[0018] The sides of the shaping tooling are spaced apart from the sides of the front cover plate. Therefore, the sides of the front cover plate are not covered by the shaping tooling. When the locking tooling is installed on the curved double-glass photovoltaic module, the locking tooling can directly contact the front cover plate, so that the shaping tooling can avoid the locking tooling, preventing the shaping tooling and the locking tooling from interfering with each other during use.

[0019] Specifically, the length of the shaping tool is L1, the spacing between the first locking tool and the second tool is L2, and the first locking tool and the second locking tool are located on both sides of the shaping tool along the length direction. The first locking tool can be abutted against one side of the shaping tool along the length direction, and the second locking tool can be abutted against the other side of the shaping tool along the length direction. At this time, the use of the first locking tool and the second locking tool will not interfere with the shaping tool. In this case, L1=L2. It is also possible to set the spacing between the first locking tool and the second locking tool to be greater than the length of the shaping tool, so that the first locking tool and the second locking tool are both spaced apart from the shaping tool.

[0020] Alternatively, the width of the shaping tool is W1, the spacing between the first locking tool and the second tool is W2, and the first locking tool and the second locking tool are located on both sides of the shaping tool in the width direction. The first locking tool can be abutted against one side of the shaping tool in the width direction, and the second locking tool can be abutted against the other side of the shaping tool in the width direction. At this time, the use of the first locking tool and the second locking tool will not interfere with the shaping tool. In this case, W1=W2. It is also possible to set the spacing between the first locking tool and the second locking tool to be greater than the width of the shaping tool, so that the first locking tool and the second locking tool are both spaced apart from the shaping tool.

[0021] Of course, locking tools may also be distributed on both sides of the shaping tool in the length direction and both sides in the width direction.

[0022] When the length of the shaping tooling is shorter than the front cover plate, the first locking tooling and the second locking tooling can be used to be respectively assembled on both sides of the length direction of the front cover plate. When the width of the shaping tooling is narrower than the front cover plate, the first locking tooling and the second locking tooling can be respectively assembled on both sides of the width direction of the front cover plate. The use of the shaping tooling and the locking tooling is not easy to interfere with each other, thereby ensuring the clamping stability of the locking tooling on the curved double-glass photovoltaic module.

[0023] In a possible application, when the locking tool clamps the curved double-glass photovoltaic module, the shaping tool can be removed, and the curved double-glass photovoltaic module is clamped and fixed only by the locking tool. Since there is no overlapping part between the shaping tool and the locking tool, when the shaping tool is removed, the locking tool will not interfere with the removal process of the shaping tool.

[0024] In some technical schemes, optionally, the locking tool includes: a first locking plate, a second locking plate and a locking member, the locking member is connected to the first locking plate and the second locking plate, the locking member is used to adjust the distance between the first locking plate and the second locking plate, and the first locking plate and the second locking plate are used to clamp the curved double-glass photovoltaic module.

[0025] The first locking plate and the second locking plate are used to clamp the curved double-glass photovoltaic module. Specifically, the first locking plate contacts the front cover plate, the second locking plate contacts the rear cover plate, and the front cover plate and the rear cover plate are located between the first locking plate and the second locking plate. When the locking member is connected to the first locking plate and the second locking plate, the locking member can adjust the distance between the first locking plate and the second locking plate. When the curved double-glass photovoltaic module needs to be clamped, the locking member reduces the distance between the first locking plate and the second locking plate, so that the first locking plate and the second locking plate clamp the curved double-glass photovoltaic module. When the locking fixture needs to be disassembled, the locking member increases the distance between the first locking plate and the second locking plate, so that the locking fixture can be separated from the curved double-glass photovoltaic module.

[0026] In some technical solutions, optionally, the locking member includes a bolt, a through hole is provided on the first locking plate, a threaded hole is provided on the second locking plate, and the bolt passes through the through hole and is connected to the threaded hole.

[0027] When the bolt is connected to the threaded hole, when the bolt is rotated, the thread can drive the second locking plate to approach or move away from the first locking plate, so that the first locking plate and the second locking plate can be installed or removed from the curved double-glass photovoltaic module.

[0028] In some technical schemes, optionally, the first locking plate includes: a first locking portion, which is used to connect to the locking member; a second locking portion, one end of the second locking portion is connected to one end of the first locking portion, and the second locking portion extends in a direction away from the second locking plate; a third locking portion, one end of the third locking portion is connected to the other end of the second locking portion, and the third locking portion is used to clamp the curved double-glass photovoltaic module with the second locking plate.

[0029] The first locking portion is provided with a through hole, and the locking member can pass through the first locking portion, so that the locking member can adjust the distance between the first locking portion and the second locking plate.

[0030] The second locking portion extends in a direction away from the second locking plate, so the distance between the first locking portion and the second locking plate is smaller than the distance between the third locking portion and the second locking plate. When the locking member reduces the distance between the first locking plate and the second locking plate, the first locking portion may have contacted the second locking plate when there is a gap between the third locking portion and the second locking plate, and the third locking portion cannot continue to approach the second locking plate.

[0031] When the first locking portion contacts the second locking plate, the distance between the third locking portion and the second locking plate is the smallest. The first locking portion and the second locking plate cooperate with each other to prevent the third locking portion and the second locking plate from further shortening the distance, thereby preventing the third locking portion and the second locking plate from clamping the curved double-glass photovoltaic module too tightly, thereby avoiding damage to the curved double-glass photovoltaic module.

[0032] In some technical schemes, optionally, the locking tool also includes: a first buffer member connected to the first locking plate, the first buffer member is located on the side of the first locking plate facing the second locking plate; a second buffer member connected to the second locking plate, the second buffer member is located on the side of the second locking plate facing the first locking plate.

[0033] A first buffer is arranged on the first locking plate. When the locking tool clamps the curved double-glass photovoltaic module, the first buffer is located between the first locking plate and the front cover plate to avoid rigid contact between the first locking plate and the front cover plate, thereby avoiding damage to the front cover plate.

[0034] Similarly, a second buffer is provided on the second locking plate. When the locking tool clamps the curved double-glass photovoltaic module, the second buffer is located between the second locking plate and the rear cover plate to avoid rigid contact between the second locking plate and the rear cover plate, thereby avoiding damage to the rear cover plate.

[0035] In some technical solutions, optionally, the shaping tooling includes: a multi-curved surface shaping tooling, and the multi-curved surface shaping tooling is used to fit with the curved double-glass photovoltaic module.

[0036] For the curved double-glass photovoltaic modules in the related art, the front cover and the rear cover are usually single-arch or multi-arch shapes. In order to increase the contact area between the shaping tooling and the front cover, the shaping tooling is also set to a multi-curved shape, so that the shaping tooling can fit tightly with the front cover, thereby improving the uniformity of force on the front cover.

[0037] In some technical solutions, optionally, the multi-curved shaping tool has crests and troughs, and the locking notches are arranged at the crests and / or troughs.

[0038] The multi-curved surface shaping tooling is a multi-arch structure, so that the multi-curved surface shaping tooling has crests and troughs, and locking notches are formed on the crests and / or troughs, so that the multi-curved surface shaping tooling can avoid the locking tooling.

[0039] In some technical solutions, optionally, the shaping tooling includes a metal tooling or an epoxy resin tooling.

[0040] In some technical solutions, optionally, the locking tooling includes a stainless steel tooling or an aluminum alloy tooling.

[0041] In some technical solutions, optionally, the length H1 of the locking tool satisfies, 15 mm ≤ H1 ≤ 20 mm; and / or the width H2 of the locking tool satisfies, 10 mm ≤ H2 ≤ 20 mm.

DETAILED DESCRIPTION

[0058] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0059] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0060] Refer to the following Figures 3 to 12 The invention describes a lamination tool for a curved double-glass photovoltaic module provided in accordance with some embodiments of the invention.

[0061] Combination Figure 3 and Figure 7 As shown, in an embodiment of the utility model, a laminating tool for a curved double-glass photovoltaic module, a shaping tool 100 and a locking tool 200 are proposed. The shaping tool 100 is used to be pressed onto the curved double-glass photovoltaic module 300 to be laminated, and the locking tool 200 is used to clamp the curved double-glass photovoltaic module 300. The shaping tool 100 and the locking tool 200 are used to cooperate with different positions on the curved double-glass photovoltaic module 300.

[0062] During the assembly process of the curved double-glass photovoltaic module 300, the front cover 310, the rear cover 320, the packaging film 330 and the power generation element 340 need to be stacked. The packaging film 330 is used to bond the front cover 310 and the rear cover 320. In order to ensure that the front cover 310 and the rear cover 320 fit tightly, the front cover 310 needs to apply pressure to the packaging film 330. If the packaging film 330 is pressed only by the weight of the front cover 310 itself, it is difficult to improve the tightness of the fit between the front cover 310 and the rear cover 320 due to the insufficient weight of the front cover 310. In the present invention, a shaping tool 100 is used to press onto the curved double-glass photovoltaic module 300. The shaping tool 100 applies pressure to the front cover plate 310, thereby increasing the bonding force between the front cover plate 310 and the rear cover plate 320, so that the front cover plate 310 and the rear cover plate 320 can fit tightly together. During the pressing process, the shaping tool 100 completely relies on its own gravity, so that the front cover plate 310 is evenly stressed, ensuring that the front cover plate 310 and the rear cover plate 320 can be in good contact, and also preventing the power generation element 340 from cracking.

[0063] When the front cover 310 is pressed together, the locking tool 200 can be used to clamp the curved double-glass photovoltaic module 300 to ensure good contact between the front cover 310 and the rear cover 320, which can effectively reduce the defective output such as empty glue, bubbles, glass misalignment, etc. during the lamination process and improve the product qualification rate.

[0064] The shaping tool 100 and the locking tool 200 cooperate with different positions on the curved double-glass photovoltaic module 300, so as to avoid mutual interference between the shaping tool 100 and the locking tool 200 and ensure the stability of the shaping tool 100 and the locking tool 200.

[0065] In the related art, the front cover 310 and the rear cover 320 are usually tempered glass with a thickness of 2 mm to 8 mm. The thickness of the front cover 310 and the rear cover 320 can be the same or different. The packaging film 330 can be made of ethylene-vinyl acetate copolymer, polyethylene, polyvinyl butyral, etc. The power generation unit can be crystalline silicon or thin film battery.

[0066] In a possible application, the effective clamping height of the locking tool 200 is equal to the sum of the thicknesses of the front cover plate 310 and the rear cover plate 320. The locking tool 200 follows the product into the lamination process, and after the lamination is completed, the locking tool 200 is removed, and the locking tool 200 can be used repeatedly.

[0067] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, a locking notch 110 is provided on the shaping tool 100 , and a portion of the locking tool 200 extends into the locking notch 110 , so that the shaping tool 100 avoids the locking tool 200 .

[0068] A locking notch 110 is formed on the shaping tooling 100. When the locking tooling 200 is installed on the curved double-glass photovoltaic module 300, a portion of the locking tooling 200 is located in the locking notch 110. The locking notch 110 can avoid the locking tooling 200 to prevent the shaping tooling 100 and the locking tooling 200 from interfering with each other during use.

[0069] The larger the contact area between the shaping tool 100 and the front cover plate 310, the more uniform the force on the front cover plate 310. Therefore, when the length of the shaping tool 100 is equal to the length of the front cover plate 310, and the width of the shaping tool 100 is equal to the width of the front cover plate 310, the shaping tool 100 can completely cover the front cover plate 310, thereby improving the uniformity of force on the front cover plate 310. In order to prevent the shaping tool 100 from interfering with the installation of the locking tool 200, a locking notch 110 is provided on the side of the shaping tool 100, so that the locking tool 200 can clamp the front cover plate 310 and the rear cover plate 320, thereby ensuring the stability of the locking tool 200 in clamping the curved double-glass photovoltaic module 300.

[0070] In a possible application, when the locking tool 200 clamps the curved double-glass photovoltaic module 300, the shaping tool 100 can be removed, and the curved double-glass photovoltaic module 300 is clamped and fixed only by the locking tool 200. Due to the presence of the locking notch 110, when the shaping tool 100 is removed, the locking tool 200 will not interfere with the removal process of the shaping tool 100.

[0071] In some embodiments, optionally, the number of the locking notches 110 is multiple, and the multiple locking notches 110 are arranged along the length direction of the shaping tool 100 ( Figure 5 The arrow at the middle mark a points to the length direction of the shaping tool 100) and / or the width direction of the shaping tool 100 ( Figure 5 The arrow at the middle mark b points to the width direction of the shaping tooling 100 , and the locking tooling 200 is distributed at intervals. There are multiple locking toolings 200 and multiple locking notches 110 correspond one to one.

[0072] In order to ensure that the front cover plate 310 can be evenly stressed, it is necessary to use locking fixtures 200 to clamp the front cover plate 310 on both sides along the length direction to prevent the front cover plate 310 from tilting on one side and ensure the tight contact between the front cover plate 310 and the rear cover plate 320. Similarly, the locking fixtures 200 can also be used to clamp the front cover plate 310 on both sides along the width direction. Accordingly, in order to ensure that the locking fixture 200 and the front cover plate 310 are stably matched, it is necessary to set locking notches 110 on both sides of the shaping fixture 100 along the length direction, or to set locking notches 110 on both sides of the shaping fixture 100 along the width direction. Of course, in order to further ensure the uniformity of force on the front cover plate 310, locking notches 110 can also be set on both sides of the shaping tooling 100 along the length direction and both sides of the width direction, so that the locking tooling 200 can clamp the curved double-glass photovoltaic module 300 along both sides of the length direction and both sides of the width direction of the front cover plate 310.

[0073] Multiple locking notches 110 can be arranged at intervals along the length direction and / or width direction of the shaping tooling 100, so that multiple locking tooling 200 can be used to clamp the curved double-glass photovoltaic module 300 at the same time to avoid displacement between the front cover plate 310 and the rear cover plate 320.

[0074] like Fig.12As shown, in some embodiments, optionally, the number of locking tools 200 is multiple, and the multiple locking tools 200 include: a first locking tool 210 and a second locking tool 220. The first locking tool 210 and the second locking tool 220 are respectively located on both sides of the shaping tool 100 along the length direction, the length of the shaping tool 100 is L1, the spacing between the first locking tool 210 and the second locking tool 220 is L2, and L1 and L2 satisfy that L1≤L2. Alternatively, the first locking tool 210 and the second locking tool 220 are respectively located on both sides of the shaping tool 100 along the width direction, the width of the shaping tool 100 is W1, the spacing between the first locking tool 210 and the second locking tool 220 is W2, and W1 and W2 satisfy that W1≤W2.

[0075] The sides of the shaping tooling 100 are spaced apart from the sides of the front cover plate 310. Therefore, the sides of the front cover plate 310 are not covered by the shaping tooling 100. When the locking tooling 200 is installed on the curved double-glass photovoltaic module 300, the locking tooling 200 can directly contact the front cover plate 310, so that the shaping tooling 100 can avoid the locking tooling 200, thereby preventing the shaping tooling 100 and the locking tooling 200 from interfering with each other during use.

[0076] Specifically, the length of the shaping tool 100 is L1, the spacing between the first locking tool 210 and the second tool is L2, and the first locking tool 210 and the second locking tool 220 are located on both sides of the shaping tool 100 along the length direction. The first locking tool 210 can be abutted against one side of the shaping tool 100 along the length direction, and the second locking tool 220 can be abutted against the other side of the shaping tool 100 along the length direction. At this time, the use of the first locking tool 210 and the second locking tool 220 will not interfere with the shaping tool 100. In this case, L1=L2. It is also possible to set the spacing between the first locking tool 210 and the second locking tool 220 to be greater than the length of the shaping tool 100, so that the first locking tool 210 and the second locking tool 220 are both spaced apart from the shaping tool 100.

[0077] Alternatively, the width of the shaping tool 100 is W1, the spacing between the first locking tool 210 and the second tool is W2, and the first locking tool 210 and the second locking tool 220 are located on both sides of the shaping tool 100 along the width direction. The first locking tool 210 can be abutted against one side of the shaping tool 100 along the width direction, and the second locking tool 220 can be abutted against the other side of the shaping tool 100 along the width direction. At this time, the use of the first locking tool 210 and the second locking tool 220 will not interfere with the shaping tool 100. In this case, W1=W2. It is also possible to set the spacing between the first locking tool 210 and the second locking tool 220 to be greater than the width of the shaping tool 100, so that the first locking tool 210 and the second locking tool 220 are both spaced apart from the shaping tool 100.

[0078] Of course, locking tools 200 may also be distributed on both sides of the shaping tool 100 in the length direction and both sides in the width direction.

[0079] When the length of the shaping tool 100 is shorter than the front cover plate 310, the first locking tool 210 and the second locking tool 220 can be used to be respectively assembled on both sides of the length direction of the front cover plate 310. When the width of the shaping tool 100 is narrower than the front cover plate 310, the first locking tool 210 and the second locking tool 220 can be used to be respectively assembled on both sides of the width direction of the front cover plate 310. The shaping tool 100 and the locking tool 200 are not easy to interfere with each other, thereby ensuring the clamping stability of the curved double-glass photovoltaic module 300 by the locking tool 200.

[0080] In a possible application, when the locking tool 200 clamps the curved double-glass photovoltaic module 300, the shaping tool 100 can be removed, and the curved double-glass photovoltaic module 300 is clamped and fixed only by the locking tool 200. Since there is no overlapping part between the shaping tool 100 and the locking tool 200, when the shaping tool 100 is removed, the locking tool 200 will not interfere with the removal process of the shaping tool 100.

[0081] Combination Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, optionally, the locking tool 200 includes: a first locking plate 230, a second locking plate 240 and a locking member 250, the locking member 250 is connected to the first locking plate 230 and the second locking plate 240, the locking member 250 is used to adjust the distance between the first locking plate 230 and the second locking plate 240, and the first locking plate 230 and the second locking plate 240 are used to clamp the curved double-glass photovoltaic module 300.

[0082] The first locking plate 230 and the second locking plate 240 are used to clamp the curved double-glass photovoltaic module 300. Specifically, the first locking plate 230 contacts the front cover plate 310, and the second locking plate 240 contacts the rear cover plate 320, and the front cover plate 310 and the rear cover plate 320 are located between the first locking plate 230 and the second locking plate 240. When the locking member is connected to the first locking plate 230 and the second locking plate 240, the locking member can adjust the distance between the first locking plate 230 and the second locking plate 240. When the curved double-glass photovoltaic module 300 needs to be clamped, the locking member reduces the distance between the first locking plate 230 and the second locking plate 240, so that the first locking plate 230 and the second locking plate 240 clamp the curved double-glass photovoltaic module 300. When the locking fixture 200 needs to be disassembled, the locking member increases the distance between the first locking plate 230 and the second locking plate 240 , so that the locking fixture 200 can be separated from the curved double-glass photovoltaic module 300 .

[0083] Combination Figure 8 and Fig. 9 As shown, in some embodiments, optionally, the locking member 250 includes a bolt, a through hole 231 is provided on the first locking plate 230, a threaded hole is provided on the second locking plate 240, and the bolt passes through the through hole 231 and is connected to the threaded hole.

[0084] When the bolt is connected to the threaded hole, when the bolt is rotated, the thread can drive the second locking plate 240 to approach or move away from the first locking plate 230, so that the first locking plate 230 and the second locking plate 240 can be installed or removed from the curved double-glass photovoltaic module 300.

[0085] In other embodiments, the locking member 250 includes a screw and a nut, the screw passes through the first locking plate 230 and the second locking plate 240, and then the nut is connected to the screw.

[0086] Combination Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, optionally, the first locking plate 230 includes: a first locking portion 232, a second locking portion 233 and a third locking portion 234, the first locking portion 232 is used to connect with the locking member 250, one end of the second locking portion 233 is connected to one end of the first locking portion 232, the second locking portion 233 extends in a direction away from the second locking plate 240, one end of the third locking portion 234 is connected to the other end of the second locking portion 233, and the third locking portion 234 is used to clamp the curved double-glass photovoltaic module 300 with the second locking plate 240.

[0087] The first locking portion 232 is provided with a through hole 231 , and the locking member 250 can pass through the first locking portion 232 , so that the locking member 250 can adjust the distance between the first locking portion 232 and the second locking plate 240 .

[0088] The second locking portion 233 extends in a direction away from the second locking plate 240, so the distance between the first locking portion 232 and the second locking plate 240 is smaller than the distance between the third locking portion 234 and the second locking plate 240. When the locking member 250 reduces the distance between the first locking plate 230 and the second locking plate 240, the first locking portion 232 may have contacted the second locking plate 240 when there is a gap between the third locking portion 234 and the second locking plate 240, and the third locking portion 234 cannot continue to approach the second locking plate 240.

[0089] When the first locking portion 232 contacts the second locking plate 240, the distance between the third locking portion 234 and the second locking plate 240 is the smallest. The first locking portion 232 and the second locking plate 240 cooperate with each other to prevent the third locking portion 234 and the second locking plate 240 from further shortening the distance, thereby preventing the third locking portion 234 and the second locking plate 240 from clamping the curved double-glass photovoltaic module 300 too tightly, thereby preventing damage to the curved double-glass photovoltaic module 300.

[0090] In a possible application, the first locking portion 232 , the second locking portion 233 and the third locking portion 234 are an integrally formed structure.

[0091] like Fig.11 As shown, in some embodiments, optionally, the locking tool 200 also includes: a first buffer 260 and a second buffer 270, the first buffer 260 is connected to the first locking plate 230, the first buffer 260 is located on the side of the first locking plate 230 facing the second locking plate 240, the second buffer 270 is connected to the second locking plate 240, and the second buffer 270 is located on the side of the second locking plate 240 facing the first locking plate 230.

[0092] A first buffer member 260 is provided on the first locking plate 230. When the locking tool 200 clamps the curved double-glass photovoltaic module 300, the first buffer member 260 is located between the first locking plate 230 and the front cover plate 310 to avoid rigid contact between the first locking plate 230 and the front cover plate 310 and to avoid damage to the front cover plate 310.

[0093] Similarly, a second buffer member 270 is provided on the second locking plate 240. When the locking tooling 200 clamps the curved double-glass photovoltaic module 300, the second buffer member 270 is located between the second locking plate 240 and the rear cover plate 320 to avoid rigid contact between the second locking plate 240 and the rear cover plate 320, thereby avoiding damage to the rear cover plate 320.

[0094] Exemplarily, the first buffer member 260 and the second buffer member 270 are rubber pads or silicone pads.

[0095] In some embodiments, optionally, the shaping tool 100 includes: a multi-curved surface shaping tool, and the multi-curved surface shaping tool is used to fit with the curved double-glass photovoltaic module 300.

[0096] For the curved double-glass photovoltaic module 300 in the related art, the front cover plate 310 and the rear cover plate 320 are usually single-arch or multi-arch shapes. In order to increase the contact area between the shaping tool 100 and the front cover plate 310, the shaping tool 100 is also set to a multi-curved shape, so that the shaping tool 100 can fit tightly with the front cover plate 310, thereby improving the force uniformity of the front cover plate 310.

[0097] In some embodiments, optionally, the multi-curved shaping tool has crests 120 and troughs 130 , and the locking notches 110 are disposed at the crests 120 and / or the troughs 130 .

[0098] The multi-curved surface shaping tooling is a multi-arch structure, so that the multi-curved surface shaping tooling has crests 120 and troughs 130 , and locking notches 110 are formed on the crests 120 and / or troughs 130 , so that the multi-curved surface shaping tooling can avoid the locking tooling 200 .

[0099] In some embodiments, optionally, the shaping tool 100 includes a metal tool or an epoxy resin tool.

[0100] The shaping tool 100 is mainly made of metal, epoxy resin or other polymer materials and has a certain weight. The size and shape of the shaping tool 100 are consistent with the front cover plate 310 , which can ensure good contact between the shaping tool 100 and the front cover plate 310 .

[0101] In some embodiments, optionally, the locking tool 200 includes a stainless steel tool or an aluminum alloy tool.

[0102] like Figure 8 As shown, in some embodiments, optionally, the length H1 of the locking tool 200 satisfies, 15 mm ≤ H1 ≤ 20 mm; and / or the width H2 of the locking tool 200 satisfies, 10 mm ≤ H2 ≤ 20 mm.

[0103] For example, H1 may be 15 mm, 18 mm or 20 mm, and H2 may be 10 mm, 15 mm or 20 mm.

[0104] In a possible application, the preparation process of the curved double-glass photovoltaic module flows as follows: battery cell welding, stacking, pressing with the shaping tool 100, locking with the locking tool 200, lamination, removing the locking tool 200 (after removing the locking tool 200, the locking step of the locking tool 200 can be performed again), framing, curing, and testing.

[0105] The preparation method of the curved double-glass photovoltaic module is a one-time lamination process, which simplifies the process flow of curved photovoltaic products.
