[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 2 to 5As shown in the figure, a production device for a high-strength photovoltaic module according to an embodiment of the present invention is applicable to the above-mentioned high-strength photovoltaic module. The production device includes a machine table 7; a glue injection box 8 and a mold 9 are fixedly connected to the top surface of the machine table 7 and are arranged closely; a through groove 10 capable of passing through carbon fiber is formed through both end faces of the glue injection box 8; a cavity 11 capable of injecting polyurethane is formed inside the glue injection box 8; the through groove 10 penetrates through the middle of the cavity 11; a forming cavity 12 communicating with the through groove 10 is formed inside the mold 9; the cross section of the forming cavity 12 is the same as that of the frame 1; During specific implementation, a wire pay-off machine is arranged at one end of the machine table 7 close to the glue injection box 8, and multiple rolls of carbon fiber are arranged on the wire pay-off machine; a glue injection machine 18 is arranged on one side of the middle of the machine table 7, and the glue injection machine 18 can inject polyurethane into the cavity 11 of the glue injection box 8; a tractor for traction and a cutting machine for cutting are arranged at one end of the machine table 7 close to the glue injection box 8; During production, the wire pay-off machine releases carbon fiber, and multiple carbon fibers pass through the through groove 10 and the cavity 11 of the glue injection box 8. At the same time, the glue injection machine 18 injects molten polyurethane into the cavity 11 of the glue injection box 8. A large amount of molten polyurethane will be wrapped around the outside of the carbon fiber when it passes through the cavity 11, and they will enter the forming cavity 12 of the mold 9 together. After cooling and forming, a frame bar of the frame 1 is formed. The frame body of the frame 1 is pulled by the tractor and pulled out from the forming cavity 12 of the mold 9. At the same time, the frame body of the frame 1 is cooled and hardened, and then cut by the cutting machine to form a frame bar with a fixed length; finally, the frame 1 is formed through assembly; By setting the glue injection box 8, the carbon fiber can be stably and accurately buried in the polyurethane, so that the overall strength of the formed frame 1 is stable and consistent, thus ensuring the quality consistency of the frame 1; By setting the mold 9 and the through forming cavity 12, the frame bars of the frame 1 can be continuously processed and produced, thereby improving the production efficiency of the frame 1.

[0023] As Figures 3 to 7 As shown in the figure, a feed baffle 13 is bolted to one end of the through groove 10 of the glue injection box 8 away from the mold 9; a feed hole 14 for passing through carbon fiber is formed in the middle of the feed baffle 13; a material distribution mesh plate 15 is fixedly connected to one side of the feed baffle 13 close to the mold 9; During specific implementation, a first groove is formed on one side of the feed baffle 13 close to the mold 9, and the inner side of the first groove matches the outer side of the material distribution mesh plate 15; a second groove can also be formed on one side of the material distribution mesh plate 15 close to the feed baffle 13. Therefore, after the material distribution mesh plate 15 is installed in the first groove of the feed baffle 13 through bolts, there is a depth of the second groove of the material distribution mesh plate 15 between the feed hole 14 in the middle of the feed baffle 13 and the mesh holes of the material distribution mesh plate 15; the feed baffle 13 is then fixedly installed in the through groove 10 of the glue injection box 8 through bolts; During production, it is necessary to pass the carbon fiber through the glue injection box 8. At this time, it is necessary to first disassemble and separate the feeding baffle 13 and the material distribution mesh plate 15, concentrate multiple carbon fibers and pass them through the feeding hole 14 in the middle of the feeding baffle 13, and then disperse the multiple carbon fibers so that each carbon fiber passes through different mesh holes on the material distribution mesh plate 15 respectively. Moreover, the shape of the area surrounded by the mesh holes through which the carbon fiber passes through the material distribution mesh plate 15 is the same as the shape of the molding cavity 12 of the mold 9. Then, the material distribution mesh plate 15 is installed in the first groove of the feeding baffle 13 through bolts. The carbon fiber passing through the mesh holes of the material distribution mesh plate 15 is sequentially passed through the through groove 10 and the molding cavity 12 of the mold 9 and straightened. Finally, the feeding baffle 13 is installed at the through groove 10. Since the shape of the area surrounded by the mesh holes through which the carbon fiber passes through the material distribution mesh plate 15 is the same as the shape of the molding cavity 12 of the mold 9, the shape of the inner cavity 11 inside the glue injection box 8 and the molding cavity 12 of the mold 9 is the same. Therefore, after the frame bar of the frame 1 is manufactured, the carbon fiber inside can be evenly and stably distributed, thus ensuring the strength consistency of the frame 1. Through the gap between the feeding baffle 13 and the material distribution mesh plate 15, it is convenient for the distribution of carbon fiber and also convenient for adjusting the distribution of carbon fiber inside the frame 1.

[0024] As Figures 6 to 8 shown, a sealing plug 16 and a sealing sliding sleeve 17 can be installed in the mesh holes of the material distribution mesh plate 15. During specific implementation, external threads are provided on the outer ring of the sealing plug 16, and a convex ring is provided on the outer ring at one end, and a hexagonal groove is provided in the middle of this end. Threads matching the sealing plug 16 are provided inside the mesh holes of the material distribution mesh plate 15. The sealing plug 16 is installed into the mesh holes of the material distribution mesh plate 15 from the side of the material distribution mesh plate 15 close to the feeding baffle 13, and the convex ring on the outer ring of the sealing plug 16 covers the outer ring of the mesh holes of the material distribution mesh plate 15. By providing the sealing plug 16, the mesh holes of the material distribution mesh plate 15 can be blocked and sealed to prevent the polyurethane in the inner cavity 11 of the glue injection box 8 from leaking into the space between the feeding baffle 13 and the material distribution mesh plate 15, resulting in the adhesion of the carbon fiber between the feeding baffle 13 and the material distribution mesh plate 15. The sealing sliding sleeve 17 is made of high-temperature resistant rubber material, and ring pieces are provided on the outer rings at both ends of the sealing sliding sleeve 17. During installation, the sealing sliding sleeve 17 is inserted into the mesh holes of the material distribution mesh plate 15 so that the ring pieces at both ends of the sealing sliding sleeve 17 are respectively pressed on the outer sides at both ends of the mesh holes of the material distribution mesh plate 15. Moreover, the shape formed by multiple sealing sliding sleeves 17 on the material distribution mesh plate 15 is the same as the shape of the molding cavity 12 of the mold 9. The carbon fiber passes through the inner ring of the sealing sleeve 17 to form a seal between the carbon fiber and the mesh holes of the material distribution mesh plate 15; and, since the carbon fiber moves from the material distribution mesh plate 15 to the inside of the injection box 8, the polyurethane in the inner cavity 11 can be blocked from entering between the feed baffle 13 and the material distribution mesh plate 15; By providing 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 also the leakage of the polyurethane in the inner cavity 11 is prevented.

[0025] like Figures 3 to 5 As shown, a discharge baffle 19 is bolted to one end of the through slot 10 of the injection box 8 close to 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; During specific implementation, the discharge baffle 19 is fixedly installed at one end of the through groove 10 close to the mold 9 by bolts; the carbon fiber and polyurethane are blocked by the discharge baffle 19 to enter the molding cavity 12 of the mold 9 from the outlet 20; this not only facilitates the carbon fiber and polyurethane to enter the mold 9, but also avoids the leakage of polyurethane due to the blocking of the discharge baffle 19.

[0026] like Figures 3 to 5 As shown, both sides of the glue injection box 8 are provided with mounting grooves 21; a heating plate 22 is provided inside the mounting groove 21; and a partition plate 23 is bolted to the opening of the mounting groove 21; In specific implementation, a convex strip is provided on the inner wall of the installation groove 21, and a notch matching the convex strip is provided on the side of the heating plate 22. After the heating plate 22 is installed inside the installation groove 21 along the convex strip, it is fixed and locked with bolts. Finally, the partition plate 23 is fixed to the opening of the installation groove 21 by bolts. The inner cavity 11 of the glue injection box 8 is heated by the provided heating plate 22 to ensure that the polyurethane in the inner cavity 11 is in a molten state, thereby avoiding adhesion and blockage inside the glue injection box 8 caused by solidification of the polyurethane.

[0027] like Figure 2 As shown, a yarn guide plate 24 is fixedly connected to one end of the machine platform 7 close to the glue injection box 8; In specific implementation, when the pay-off machine releases the carbon fiber, each carbon fiber passes through different holes on the yarn guide plate 24, so that each carbon fiber is dispersed from each other, thereby avoiding the entanglement and knotting of the carbon fiber during the transportation process.

[0028] 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 middle of the bottom surface of the upper mold; and a groove is opened in the middle of the top surface of the lower mold; In specific implementation, after the upper die and the lower die of the mold 9 are closed, the protrusions on the bottom surface of the upper die are inserted into the grooves on the top surface of the lower die, thereby forming a molding cavity 12 for the molding of the frame body of the frame 1; and cooling channels with circulating water cooling are arranged inside both the upper die and the lower die of the mold 9 to cool the inside of the molding cavity 12; by setting the mold 9 into a split upper die and lower die, it is convenient to maintain and clean the molding cavity 12.

[0029] As Figure 2 , Figures 9 to 11 shown, on both sides of the top surface at one end of the machine table 7 away from the glue injection box 8, slide rails 25 are arranged; a cross beam 26 is arranged 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 cross beam 26; In specific implementation, a fixing block with a card slot is fixedly connected to the top surface of the slider of the slide rail 25, and clamping blocks capable of matching with the fixing block are fixedly connected to both ends of the cross beam 26; during installation, the clamping blocks at both ends of the cross beam 26 are respectively clamped into the card slots of the fixing blocks on both sides; During production, the carbon fiber needs to pass through the glue injection box 8 and the mold 9 in sequence. After the carbon fiber passes through the mesh holes of the pulling mesh plate 27 correspondingly, it is fixed, so that the distribution of the carbon fiber always remains in a fixed state, thereby ensuring the strength consistency of the frame 1. After that, the injection molding machine 18 injects molten polyurethane into the inner cavity 11 of the glue injection box 8, then pushes the cross beam 26 to slide along the slide rail 25 away from the mold 9, and the pulling mesh plate 27 pulls the carbon fiber to move, bringing the polyurethane in the inner cavity 11 into the molding cavity 12 of the mold 9 for molding until the formed frame strip of the frame 1 is pulled out from the molding cavity 12 of the mold 9; at this time, the excess carbon fiber is cut off, the cross beam 26 is removed from the slide rail 25, and the frame strip of the frame 1 is put into the traction machine for traction manufacturing; thus, it is convenient for the traction work at the beginning of production and improves the production efficiency.

[0030] As Figures 9 to 11 shown, a fixed strip plate 28 is fixedly connected to the middle of the top surface of the cross beam 26; a lower pressing plate 29 capable of being pressed down is arranged on the top surface of the fixed strip plate 28; a rubber strip 30 is fixedly connected to the bottom surface of the lower pressing plate 29; In specific implementation, screws are fixedly connected to both ends of the top surface of the fixed strip plate 28, through holes matching with the screws are opened at both ends of the lower pressing plate 29; the lower pressing plate 29 is slidably installed on the screws; nuts are threadedly installed at the tops of the screws, and the nuts cooperate with the screws to press down the lower pressing plate 29, and at the same time, a spring is arranged on the outer ring of the screws; After the carbon fiber passes through the mesh holes of the pulling mesh plate 27 correspondingly, the carbon fiber is placed between the fixed strip plate 28 and the lower pressing plate 29, the nut is rotated to push the lower pressing plate 29 to press down, so that the rubber strip 30 cooperates with the fixed strip plate 28 to fixedly press the carbon fiber, thereby avoiding the falling off of the carbon fiber during the pulling process.

[0031] As shown in Figures 1 to 2 the figure, a high-strength photovoltaic module is characterized in that: the high-strength photovoltaic module adopts the production equipment described in any one of the above 1-9, and the photovoltaic module includes a frame; a glass, an encapsulant film and a battery string are sequentially arranged from the top surface and the bottom surface to the middle on the inner side of the frame; a junction box connected to the battery string is fixedly connected to the bottom surface of the frame; wherein, the frame is formed by high-temperature extrusion molding of 80% carbon fiber and 20% polyurethane through an injection pultrusion process; The glass 2 in this application is 2.0 semi-tempered glass, and the four-point bending strength reaches ≥140MPa; the encapsulant film 3 in this application is a POE plastic film; the battery string 4 in this application adopts TOPCon high-efficiency batteries and is welded by welding tapes 6; the junction box 5 in this application adopts a three-piece photovoltaic junction box; During specific implementation, through a string welding machine device, the battery cells are welded by welding tapes 6 to form a battery string 4; the front and back of the battery string 4 are both covered with an encapsulant film 3, and then the glass 2 is covered on the front and back of the battery string 4 to form a structure of glass 2, encapsulant film 3 and battery string 4 from the outside to the inside in sequence; then, high-temperature pressing is carried out by a laminator, and the encapsulant film 3 is melted to bond the glass 2 and the battery string 4; then, the glass 2 and the 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; The frame 1 made of 80% carbon fiber and 20% polyurethane uses a glue injection box 8 to mix polyurethane and carbon fiber, so that the carbon fiber uniformly passes through a mold 9, and the polyurethane cools and solidifies to form the frame 1; since the carbon fiber is uniformly distributed along the length of the frame 1 and each carbon fiber is continuous, not only the strength of the frame 1 is improved, but also the consistency of the strength of the frame 1 is ensured; thus, not only a high-strength load-bearing capacity is provided, but also the weight of the photovoltaic module is effectively reduced, and the protection performance of the photovoltaic module is ensured.

[0032] Working principle: When manufacturing the frame 1, first, the feeding baffle 13 and the material distribution mesh plate 15 are disassembled and separated, and the sealing plug 16 is installed into the mesh hole of the material distribution mesh plate 15 from the side of the material distribution mesh plate 15 close to the feeding baffle 13, and the convex ring on the outer circle of the sealing plug 16 covers the outer circle of the mesh hole of the material distribution mesh plate 15; the sealing sliding sleeve 17 is inserted into the mesh hole of the material distribution mesh plate 15, so that the ring pieces at both ends of the sealing sliding sleeve 17 are respectively pressed on the outer sides of both ends of the mesh hole of the material distribution mesh plate 15; and the shape formed by a plurality of sealing sliding sleeves 17 on the material distribution mesh plate 15 is the same as the shape of the forming cavity 12 of the mold 9; Release carbon fiber through a wire pay-off machine. Multiple carbon fibers pass through different holes on the yarn guide plate 24 respectively, so that each carbon fiber is dispersed from each other, avoiding the situation of winding and knotting of carbon fibers during transportation; pass multiple carbon fibers through the feeding hole 14 in the middle of the feeding baffle 13 in a concentrated manner, and then disperse the multiple carbon fibers, and pass each carbon fiber through the corresponding sealing sliding sleeve 17; then pass through the through groove 10 and the forming cavity 12 of the mold 9 in sequence; install the material distribution mesh plate 15 into the first groove of the feeding baffle 13 through bolts, and then install the feeding baffle 13 into the through groove 10; The carbon fiber passing through the forming cavity 12 correspondingly passes through the mesh holes of the pulling material mesh plate 27. Place the carbon fiber between the fixed strip plate 28 and the lower pressing plate 29. Rotate the nut to push the lower pressing plate 29 downward, so that the rubber strip 30 cooperates with the fixed strip plate 28 to fix and press the carbon fiber tightly; Then, push the cross beam 26 to slide along the slide rail 25 away from the mold 9. The pulling material mesh plate 27 pulls the carbon fiber to move, and pulls the carbon fiber taut; at this time, the carbon fiber is in a horizontally straightened state between the material distribution mesh plate 15 and the pulling material 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; After that, the injection molding machine 18 injects molten polyurethane into the inner cavity 11 of the glue injection box 8. At the same time, continue to push the cross beam 26 to slide, drive the carbon fiber to move, and bring the polyurethane in the inner cavity 11 into the forming cavity 12 of the mold 9 to be molded until the frame strip of the formed frame 1 is pulled out from the forming cavity 12 of the mold 9; at this time, the extra carbon fiber is cut off, and the cross beam 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 through the cutting of the cutting machine, the frame strip of the frame 1 is formed; finally, the frame 1 is formed through assembly; When assembling a high-strength photovoltaic module, through a string welding machine device, use the welding tape 6 to weld the battery cells to form a battery string 4; cover both the front and back of the battery string 4 with the glue film 3, and then cover the glass 2 on the front and back of the battery string 4 to form a structure with the glass 2, the glue film 3 and the battery string 4 from the outside to the inside in sequence; then use a laminator for high-temperature pressing, the glue film 3 melts, and bonds the glass 2 and the battery string 4; then install and fix the glass 2 and the battery string 4 inside the frame 1, and connect the junction box 5 at the bottom of the frame 1 with the battery string 4 to form a photovoltaic module.
