[0003] With the development and popularization of carbon fiber, the technology of making frames using carbon fiber and polyurethane has also emerged. The frames made by using carbon fiber as the skeleton and polyurethane as the main material are lightweight and strong.

[0004] However, due to the uneven distribution of carbon fibers within the polyurethane, the structural strength of different parts of the manufactured frame will also be inconsistent, resulting in differences in the protective capabilities of the frame.

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] like Figures 2 to 5 As shown in the embodiment of this utility model, a production equipment for high-strength photovoltaic modules is applicable to the aforementioned high-strength photovoltaic modules. The production equipment includes a machine base 7; a glue injection box 8 and a mold 9 are fixedly connected to the top surface of the machine base 7 and closely fitted together; a through groove 10 is formed between the two end faces of the glue injection box 8, allowing carbon fiber to pass through; an inner cavity 11 for injecting polyurethane is formed inside the glue injection box 8; the through groove 10 passes through the middle of the inner cavity 11; a molding cavity 12 communicating with the through groove 10 is formed inside the mold 9; the cross-section of the molding cavity 12 is consistent with the cross-section of the frame 1.

[0035] In specific implementation, a wire feeding machine is set at one end of the machine base 7 near the glue injection box 8, and multiple rolls of carbon fiber are set on the wire feeding machine; a glue injection machine 18 is set on one side of the middle part of the machine base 7, and the glue injection machine 18 can inject polyurethane into the inner cavity 11 of the glue injection box 8; a traction machine for traction and a cutting machine for cutting are set at one end of the machine base 7 near the glue injection box 8.

[0036] During production, the wire feeding machine releases carbon fibers, and multiple carbon fibers pass through the through slot 10 and inner cavity 11 of the glue injection box 8. At the same time, the glue injection machine 18 injects molten polyurethane into the inner cavity 11 of the glue injection box 8. When the carbon fibers pass through the inner cavity 11, a large amount of molten polyurethane will be wrapped around their outer side, and they will enter the molding cavity 12 of the mold 9 together. After cooling and molding, the frame strip of the frame 1 is formed. The frame of the frame 1 is pulled out from the molding cavity 12 of the mold 9 by the traction machine. At the same time, the frame of the frame 1 cools and hardens, and is then cut by the cutting machine to form a frame strip of fixed length. Finally, the frame 1 is assembled.

[0037] By using the injection box 8, the carbon fiber can be stably and accurately embedded in the polyurethane, resulting in a stable and consistent overall strength of the frame 1, thus ensuring the quality consistency of the frame 1.

[0038] By using the mold 9 and the through forming cavity 12, the frame strips of the frame 1 can be continuously processed and produced, thereby improving the production efficiency of the frame 1.

[0039] like Figures 3 to 7 As shown, a feed baffle 13 is bolted to the end of the through groove 10 of the glue injection box 8 away from the mold 9; a feed hole 14 for passing carbon fiber is opened in the middle of the feed baffle 13; a material distribution mesh plate 15 is fixed to the side of the feed baffle 13 near the mold 9.

[0040] In specific implementation, the feed baffle 13 has a first groove on the side near the mold 9, and the inner side of the first groove matches the outer side of the distribution mesh plate 15; the distribution mesh plate 15 may also have a second groove on the side near the feed baffle 13, so that after the distribution mesh plate 15 is installed into the first groove of the feed baffle 13 by bolts, the feed hole 14 in the middle of the feed baffle 13 and the mesh of the distribution mesh plate 15 are separated by the depth of the second groove of the distribution mesh plate 15; the feed baffle 13 is then fixedly installed into the through groove 10 of the glue injection box 8 by bolts;

[0041] During production, carbon fibers need to be passed through the injection box 8. At this time, the feed baffle 13 and the distribution mesh plate 15 need to be disassembled and separated first. Multiple carbon fibers are concentrated and passed through the feed hole 14 in the middle of the feed baffle 13. Then, the multiple carbon fibers are dispersed so that each carbon fiber passes through different mesh holes on the distribution mesh plate 15. The shape of the area formed by the carbon fibers passing through the mesh holes of the distribution mesh plate 15 is consistent with the shape of the forming cavity 12 of the mold 9. Then, the distribution mesh plate 15 is installed into the first groove of the feed baffle 13 with bolts. After passing through the mesh holes of the distribution mesh plate 15, the carbon fibers pass through the through groove 10 and the forming cavity 12 of the mold 9 in sequence and are straightened. Finally, the feed baffle 13 is installed into the through groove 10.

[0042] The shape of the area formed by the carbon fiber passing through the mesh of the distribution plate 15 is consistent with the shape of the forming cavity 12 of the mold 9, so that the shape of the inner cavity 11 of the carbon fiber inside the injection box 8 is consistent with the shape of the forming cavity 12 of the mold 9. Therefore, after the frame strip of the frame 1 is manufactured, the carbon fiber inside can be evenly and stably distributed, thereby ensuring the consistency of the strength of the frame 1.

[0043] The gap between the feed baffle 13 and the distribution mesh plate 15 facilitates the distribution of carbon fibers and also makes it easier to adjust the distribution of carbon fibers within the frame 1.

[0044] like Figures 6 to 8 As shown, a sealing plug 16 and a sealing sleeve 17 can be installed inside the mesh of the material distribution mesh plate 15;

[0045] In specific implementation, the outer ring of the sealing plug 16 is threaded, and one end of the outer ring has a convex ring, and the middle of that end has a hexagonal groove; the mesh of the distribution mesh plate 15 has threads that match the sealing plug 16; the sealing plug 16 is installed into the mesh of the distribution mesh plate 15 from the side of the distribution mesh plate 15 near the feed baffle 13, and the convex ring of the outer ring of the sealing plug 16 covers the outer ring of the mesh of the distribution mesh plate 15; the sealing plug 16 can block and seal the mesh of the distribution mesh plate 15, preventing the polyurethane in the inner cavity 11 of the glue injection box 8 from leaking and entering between the feed baffle 13 and the distribution mesh plate 15, causing the carbon fiber between the feed baffle 13 and the distribution mesh plate 15 to stick together;

[0046] The sealing sleeve 17 is made of high-temperature resistant rubber, and both ends of the sealing sleeve 17 have annular plates on their outer rings. During installation, the sealing sleeve 17 is inserted into the mesh of the distribution mesh plate 15, so that the annular plates at both ends of the sealing sleeve 17 press against the outer sides of the mesh of the distribution mesh plate 15. The shape formed by the multiple sealing sleeves 17 on the distribution mesh plate 15 is consistent with the shape of the forming cavity 12 of the mold 9.

[0047] By passing carbon fiber through the inner ring of the sealing sleeve 17, a seal is formed between the carbon fiber and the mesh of the distribution mesh plate 15; and, as the carbon fiber moves from the distribution mesh plate 15 toward the interior of the glue injection box 8, it can prevent the polyurethane in the inner cavity 11 from entering between the feed baffle 13 and the distribution mesh plate 15.

[0048] By setting the sealing plug 16 and the sealing sleeve 17, not only can the carbon fiber smoothly enter the inner cavity 11 of the glue injection box 8, but the polyurethane in the inner cavity 11 is also prevented from leaking.

[0049] like Figures 3 to 5 As shown, a discharge baffle 19 is bolted to one end of the through groove 10 of the glue injection box 8 near the mold 9; an outlet 20 communicating with the molding cavity 12 is opened in the middle of the discharge baffle 19; the shape of the outlet 20 is consistent with the shape of the molding cavity 12 of the mold 9.

[0050] In practice, the discharge baffle 19 is fixedly installed on the end of the through groove 10 near the mold 9 by bolts; the discharge baffle 19 blocks the carbon fiber and polyurethane from the outlet 20 into the molding cavity 12 of the mold 9; this not only facilitates the entry of carbon fiber and polyurethane into the mold 9, but also prevents polyurethane leakage due to the blockage of the discharge baffle 19.

[0051] like Figures 3 to 5 As shown, mounting slots 21 are provided on both sides of the glue injection box 8; a heating plate 22 is provided inside the mounting slot 21; and a partition plate 23 is bolted to the opening of the mounting slot 21.

[0052] In practice, the inner wall of the mounting groove 21 is provided with a protrusion, and the side of the heating plate 22 is provided with a groove that matches the protrusion. After the heating plate 22 is installed into the interior of the mounting groove 21 along the protrusion, it is then fixed and locked with bolts. Finally, the partition 23 is fixedly installed into the opening of the mounting groove 21 with bolts.

[0053] The heating plate 22 heats the inner cavity 11 inside the glue injection box 8, ensuring that the polyurethane in the inner cavity 11 is in a molten state, thereby avoiding the solidification of polyurethane and causing internal adhesion and blockage of the glue injection box 8.

[0054] like Figure 2 As shown, a yarn guide plate 24 is fixedly connected to one end of the machine base 7 near the glue injection box 8;

[0055] In practice, when the yarn feeding machine releases carbon fibers, each carbon fiber passes through different holes on the yarn guide plate 24, so that each carbon fiber is dispersed from each other, thus avoiding the carbon fibers from tangling and knotting during the conveying process.

[0056] like Figures 2 to 3 As shown, the mold 9 includes an upper mold and a lower mold; a protrusion is fixedly connected to the center of the bottom surface of the upper mold; a groove is formed in the center of the top surface of the lower mold;

[0057] In specific implementation, after the upper and lower molds of mold 9 are closed, the protrusion on the bottom surface of the upper mold is inserted into the groove on the top surface of the lower mold, thereby forming a molding cavity 12 for forming the frame of the frame 1; and the upper and lower molds of mold 9 are both provided with circulating water cooling channels to cool the inside of the molding cavity 12; by setting mold 9 as a detachable upper and lower mold, it is convenient to maintain and clean the molding cavity 12.

[0058] like Figure 2 , Figures 9 to 11 As shown, slide rails 25 are provided on both sides of the top surface of the machine base 7 away from the glue injection box 8; a crossbeam 26 is provided between the sliders of the slide rails 25 on both sides; a pulling mesh plate 27 corresponding to the material distribution mesh plate 15 is fixedly connected to the top surface of the crossbeam 26.

[0059] In practice, the top surface of the slider of the slide rail 25 is fixedly connected to a fixing block with a slot, and both ends of the crossbeam 26 are fixedly connected to a locking block that can match the fixing block; during installation, the locking blocks at both ends of the crossbeam 26 are respectively inserted into the slots of the fixing blocks on both sides.

[0060] During production, carbon fibers are first passed sequentially through the injection box 8 and the mold 9. The carbon fibers are then fixed after passing through the corresponding holes in the pulling mesh plate 27, ensuring that the distribution of the carbon fibers remains constant and thus guaranteeing the consistent strength of the frame 1. Afterward, the injection machine 18 injects molten polyurethane into the inner cavity 11 of the injection box 8, and pushes the crossbeam 26 to slide away from the mold 9 along the slide rail 25. The pulling mesh plate 27 pulls the carbon fibers, bringing the polyurethane in the inner cavity 11 into the molding cavity 12 of the mold 9 for molding, until the frame strip of the molded frame 1 is pulled out from the molding cavity 12 of the mold 9. At this point, the excess carbon fibers are cut off, and the crossbeam 26 is removed from the slide rail 25. The frame strip of the frame 1 is then placed into the traction machine for traction manufacturing, which facilitates the traction work at the start of production and improves production efficiency.

[0061] like Figures 9 to 11 As shown, a fixing strip 28 is fixedly connected to the middle of the top surface of the crossbeam 26; a pressing plate 29 that can be pressed down is provided on the top surface of the fixing strip 28; a rubber strip 30 is fixedly connected to the bottom surface of the pressing plate 29.

[0062] In practice, screws are fixed to both ends of the top surface of the fixed strip 28, and through holes matching the screws are opened at both ends of the lower pressure plate 29; the lower pressure plate 29 is slidably mounted on the screw; a nut is threaded on the top of the screw, and the nut is used to press the lower pressure plate 29 downward with the screw; at the same time, a spring is provided on the outer ring of the screw.

[0063] After the carbon fiber passes through the mesh of the pulling mesh plate 27, it is placed between the fixing strip 28 and the lower pressure plate 29. The nut is turned to push the lower pressure plate 29 down, so that the rubber strip 30 cooperates with the fixing strip 28 to fix and press the carbon fiber, thereby preventing the carbon fiber from falling off during the pulling process.

[0064] like Figures 1 to 2 As shown, a high-strength photovoltaic module is characterized in that: the high-strength photovoltaic module adopts the production equipment described in any one of 1-9 above, and the photovoltaic module includes a frame; the inner side of the frame is provided with glass, encapsulant film and battery string in sequence from the top surface and bottom surface to the center; a junction box connected to the battery string is fixed to the bottom surface of the frame.

[0065] The frame is made of 80% carbon fiber and 20% polyurethane, and is formed by high-temperature injection pultrusion.

[0066] The glass 2 in this application is 2.0mm semi-tempered glass, and its four-point bending strength reaches ≥140MPa; the encapsulating film 3 in this application is POE plastic film; the battery string 4 in this application uses TOPCon high-efficiency batteries, which are welded together by welding strips 6; the junction box 5 in this application is a three-part photovoltaic junction box.

[0067] In practice, the battery cells are welded into a battery string 4 using a string welding machine with welding strips 6. The front and back of the battery string 4 are covered with adhesive film 3, and then glass 2 is covered on the front and back of the battery string 4, forming a structure from the outside to the inside consisting of glass 2, adhesive film 3 and battery string 4. Then, a laminator is used for high-temperature pressing, where the adhesive film 3 melts and bonds the glass 2 to the battery string 4. Finally, the glass 2 and battery string 4 are installed and fixed inside the frame 1, and the junction box 5 at the bottom of the frame 1 is connected to the battery string 4 to form a photovoltaic module.

[0068] The frame 1 is made of 80% carbon fiber and 20% polyurethane. The polyurethane and carbon fiber are mixed using a glue injection box 8, and the carbon fiber is evenly passed through the mold 9. The polyurethane cools and solidifies to form the frame 1. Because the carbon fiber is evenly distributed along the length of the frame 1 and each carbon fiber is continuous, not only is the strength of the frame 1 improved, but the consistency of the strength of the frame 1 is also guaranteed. This not only provides high load-bearing capacity, but also effectively reduces the weight of the photovoltaic module and ensures the protective performance of the photovoltaic module.

[0069] Working principle: When manufacturing frame 1, firstly, the feed baffle 13 and the distribution mesh plate 15 are disassembled and separated. The sealing plug 16 is installed from the side of the distribution mesh plate 15 near the feed baffle 13 into the mesh of the distribution mesh plate 15, and the convex ring of the outer ring of the sealing plug 16 covers the outer ring of the mesh of the distribution mesh plate 15. The sealing sleeve 17 is inserted into the mesh of the distribution mesh plate 15, so that the rings at both ends of the sealing sleeve 17 press against the outer sides of the mesh of the distribution mesh plate 15. The shape formed on the distribution mesh plate 15 by the multiple sealing sleeves 17 is consistent with the shape of the forming cavity 12 of the mold 9.

[0070] Carbon fibers are released by the yarn feeding machine, and multiple carbon fibers pass through different holes on the yarn guide plate 24, so that each carbon fiber is dispersed from each other, avoiding the carbon fibers from tangling and knotting during the conveying process; multiple carbon fibers are then passed through the feed hole 14 in the middle of the feed baffle 13, and then dispersed, with each carbon fiber passing through the corresponding sealing sleeve 17; then they pass through the through groove 10 and the forming cavity 12 of the mold 9 in sequence; the material distribution mesh plate 15 is installed into the first groove of the feed baffle 13 by bolts, and then the feed baffle 13 is installed into the through groove 10;

[0071] After passing through the forming cavity 12, the carbon fiber passes through the mesh of the pulling mesh plate 27. The carbon fiber is placed between the fixing strip 28 and the lower pressure plate 29. The nut is turned to push the lower pressure plate 29 down, so that the rubber strip 30 cooperates with the fixing strip 28 to fix and press the carbon fiber.

[0072] Then, push the crossbeam 26 to slide away from the mold 9 along the slide rail 25, and pull the carbon fiber to move and tighten it; at this time, the carbon fiber is in a horizontally straight state between the distribution mesh plate 15 and the pulling mesh plate 27, so that the carbon fiber is evenly distributed in the inner cavity 11 of the glue injection box 8 and the forming cavity 12 of the mold 9.

[0073] Next, the injection molding machine 18 injects molten polyurethane into the inner cavity 11 of the injection box 8. At the same time, it continues to push the crossbeam 26 to slide, driving the carbon fiber to move and bringing the polyurethane in the inner cavity 11 into the molding cavity 12 of the mold 9 for molding, until the frame strip of the molded frame 1 is pulled out from the molding cavity 12 of the mold 9. At this time, the excess carbon fiber is cut off, and the crossbeam 26 is removed from the slide rail 25. The frame strip of the frame 1 is put into the traction machine for traction manufacturing, and then cut by the cutting machine to form the frame strip of the frame 1. Finally, the frame 1 is formed by assembly.

[0074] When assembling high-strength photovoltaic modules, the cells are welded together to form a battery string 4 using a string welding machine with welding ribbon 6. The front and back of the battery string 4 are covered with an adhesive film 3, and then glass 2 is placed over the front and back of the battery string 4, forming a structure from the outside in consisting of glass 2, adhesive film 3, and battery string 4. A laminator is then used for high-temperature pressing, melting the adhesive film 3 and bonding the glass 2 to the battery string 4. Finally, the glass 2 and battery string 4 are installed and fixed inside the frame 1, and the junction box 5 at the bottom of the frame 1 is connected to the battery string 4 to form the photovoltaic module.
