[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0041] With the rapid development of photovoltaic technology, photovoltaic modules, as the core component of solar power generation systems, are directly related to the power generation efficiency and lifespan of the entire photovoltaic power station through their manufacturing process and quality control. In the manufacturing process of photovoltaic modules, lamination is a key step, its main function being to bond materials such as solar cells, EVA film, and backsheets under high temperature and pressure to form a stable module structure.

[0042] Currently, the lamination process mainly includes the following standardized process: First, materials such as battery cells, EVA film, and backsheet are stacked in a predetermined order, then placed in a laminator, and the EVA film is fully melted and evenly distributed by precisely controlling the heating and pressurization parameters, and finally cooled and cured to form a complete component.

[0043] However, in actual production, due to insufficient precision in controlling lamination process parameters or differences in material properties, photovoltaic modules often experience quality problems such as edge delamination, excessive adhesive overflow, and substandard cross-linking during manufacturing. These defects not only exist in the manufacturing process but also continue to manifest during the long-term operation of photovoltaic power plants, seriously affecting the stability and power generation efficiency of the modules.

[0044] To solve the above problems, please refer to... Figure 1 and Figure 2 This utility model provides a photovoltaic laminator 200, which includes a laminator 210, a conveying assembly 220, and a photovoltaic laminator frame assembly 100, with the photovoltaic laminator frame assembly 100 located between the laminator 210 and the conveying assembly 220. Specifically, the photovoltaic laminator frame assembly 100 includes multiple frame edges 110 and at least one telescopic member 120, which together form a receiving cavity 101 for accommodating a photovoltaic module 300, and the two ends of the telescopic member 120 are respectively connected to the frame edges 110 and the conveying assembly 220.

[0045] It should be noted that the laminate 210 is connected to the driver and moves closer to or further away from the conveying component 220 under the drive of the driver. As the laminate 210 gradually moves closer to the conveying component 220, since the photovoltaic laminate frame component 100 is located between the laminate 210 and the conveying component 220, the laminate 210 and the conveying component 220 will work together to squeeze the photovoltaic laminate frame component 100.

[0046] The telescopic component 120 extends in the same direction as the laminate 210, specifically... Figure 1 and Figure 2 The Z-direction allows this embodiment to utilize the telescopic member 120 to bring multiple frame frames 110 close to the conveying assembly 220 for placement on the conveying assembly 220. Furthermore, since the photovoltaic laminate frame assembly 100 has a receiving cavity 101, the photovoltaic module 300 can be received within the receiving cavity 101 and placed on the conveying assembly 220.

[0047] As the laminator approaches the conveying component 220, the laminator and the conveying component 220 work together to not only compress the photovoltaic laminate frame component 100, but also the photovoltaic module 300, so as to bond the cell, EVA film, backsheet and other materials together by compression, making the structure of the photovoltaic module 300 more stable.

[0048] In this embodiment, multiple frame frames 110 are used to enclose and form a receiving cavity 101. The laminator and conveying assembly 220 squeeze the photovoltaic module 300, so that the photovoltaic module 300 is located in a closed space, thereby restricting the flow range of various structures of the photovoltaic module 300 and the adhesive, so as to avoid the phenomenon of edge delamination and adhesive overflow of the photovoltaic module 300 during the lamination process, and improve the quality of lamination.

[0049] It is worth noting that in existing lamination technologies, to effectively control adhesive overflow and ensure lamination quality, it is usually necessary to manually place lamination frames at the edges of the laminated modules and manually remove the frames after lamination. This process not only significantly increases operational complexity but also substantially raises operating costs, becoming a major factor restricting the improvement of photovoltaic module manufacturing efficiency.

[0050] In this embodiment, the lamination frame assembly is equipped with a telescopic member 120. After lamination is completed, the telescopic member 120 can be used to raise the frame 110, allowing the photovoltaic module 300 to leave the receiving cavity 101. Subsequently, the conveying assembly 220 transports the laminated photovoltaic module 300 to another process or collects them together. The conveying assembly 220 also transports new unlaminated photovoltaic modules 300 to the location of the photovoltaic lamination frame assembly 100 for lamination. Therefore, this embodiment eliminates the need for manual placement and removal of the frame 110, reducing labor costs and improving manufacturing efficiency.

[0051] Further, please refer to Figures 1-3 In this embodiment, the multiple frame 110 is divided into two long sides 111, multiple short sides 112, and multiple movable frames 130. The two ends of each short side 112 are respectively connected to the two long sides 111, and the multiple short sides 112 are arranged parallel and spaced apart along the extension direction of the long sides 111, thereby forming multiple accommodating cavities 101 to accommodate multiple photovoltaic modules 300, thereby enabling multiple photovoltaic modules 300 to be laminated in one lamination process, improving lamination efficiency.

[0052] It should be noted that the extension direction of the long side 111 is... Figure 1 and Figure 2 The X direction is perpendicular to the Z direction.

[0053] Each movable frame 130 is located within a receiving cavity 101, and each receiving cavity 101 is formed by two long sides 111 and two short sides 112. Therefore, each receiving cavity 101 corresponds to two short sides 112, that is, each movable frame 130 corresponds to two short sides 112, and the two ends of each movable frame 130 are movably connected to the corresponding two short sides 112. Thus, the two long sides 111, multiple short sides 112, and multiple movable frames 130 are interconnected to form a complete frame with multiple receiving cavities 101, and the size of the receiving cavity 101 can be adjusted by utilizing the movable connection between the movable frames 130 and the short sides 112 to accommodate photovoltaic modules 300 of various sizes.

[0054] For details, please refer to Figure 4 When the movable frame 130 contacts one of its long sides 111, the volume of the accommodating cavity 101 is at its maximum. Please refer to [reference needed]. Figure 5 The movable frame 130 is spaced apart from the two long sides 111. Figure 5 The volume of the accommodating cavity 101 is less than Figure 4 The volume of the middle accommodating cavity 101, i.e. Figure 5 The photovoltaic modules accommodated are less than 300 Figure 4 The photovoltaic modules it houses are 300.

[0055] Based on the above, in this embodiment, a slide rail 113 is provided on the side where the short side 112 connects to the movable frame 130, allowing the movable frame 130 to slide in conjunction with the slide rail 113. The size of the accommodating cavity 101 can be adjusted by the sliding distance of the slide rail 113.

[0056] It should be noted that the sliding direction of the movable frame 130 is... Figure 1 and Figure 2 The Y-direction, X-direction, Y-direction and Z-direction are all perpendicular to each other.

[0057] Further, please refer to Figures 1-7 The photovoltaic laminator 200 in this embodiment also includes a high-temperature cloth assembly 230, which includes an upper high-temperature cloth 231 and a lower high-temperature cloth 232. The upper high-temperature cloth 231 is disposed on the laminator plate 210 and located between the laminator plate 210 and the photovoltaic laminator frame assembly 100. The lower high-temperature cloth 232 is disposed on the conveying assembly 220 and located between the conveying assembly 220 and the photovoltaic laminator frame assembly 100.

[0058] Understandably, the upper high-temperature cloth 231 is used to isolate the laminate 210 and the photovoltaic laminate frame module 100, while the photovoltaic module 300 is located within the receiving cavity 101 of the photovoltaic laminate frame module 100; that is, the upper high-temperature cloth 231 is used to isolate the photovoltaic module 300 and the laminate 210. Similarly, the lower high-temperature cloth 232 is used to isolate the conveyor module 220 and the photovoltaic laminate frame module 100; that is, the lower high-temperature cloth 232 is used to isolate the photovoltaic module 300 and the conveyor module 220.

[0059] In this embodiment, the upper high-temperature cloth 231 and the lower high-temperature cloth 232 are used to prevent the photovoltaic module 300 from contacting the laminate 210 and the conveying component 220, thereby preventing the photovoltaic module 300 from sticking to the laminate 210 or the conveying component 220. They also serve to insulate and prevent the photovoltaic module 300 from being scratched by the laminate 210 or the conveying component 220.

[0060] It should be noted that the projection of the receiving cavity 201 of the photovoltaic laminate frame assembly 100 in the moving direction of the laminate 210 is located within the outline of the upper high-temperature cloth 231 and the lower high-temperature cloth 232, so as to ensure that the photovoltaic assembly 300 will not come into contact with the laminate 210 and the conveying assembly 220.

[0061] According to the above, the conveying assembly 220 includes a base plate 221 and a roller 222. The roller 222 and the base plate 221 rotate together. The lower high-temperature cloth 232 is disposed on the base plate 221 and the roller 222. The roller 222 rotates, thereby driving the lower high-temperature cloth 232 to move relative to the base plate 221.

[0062] Understandably, since the photovoltaic module 300 is placed on the lower high-temperature cloth 232, when the lower high-temperature cloth 232 moves relative to the base plate 221 under the action of the roller 222, the photovoltaic module 300 will also move equivalent to the base plate 221, thereby conveying the laminated photovoltaic module 300 to the next process by the conveying component 220.

[0063] It should be noted that the moving direction of the lower high-temperature fabric 232 is parallel to the extending direction of the long side 111, that is... Figure 1 and Figure 2 The X direction in the equation.

[0064] Furthermore, in this embodiment, the telescopic member 120 includes a cylinder 121 and a piston 122 that are movably fitted together. One end of the piston 122 is connected to the frame 110, and the other end of the piston 122 extends into the cylinder 121. The peripheral wall of the piston 122 abuts against the inner wall of the cylinder 121.

[0065] Understandably, in this embodiment, the movement of the piston 122 relative to the cylinder 121 drives the multiple frame pieces 110 to move along the movement direction of the laminator, so that the multiple frame pieces 110 can move closer to and further away from the conveying assembly 220.

[0066] In this embodiment, the base plate 221 is provided with a receiving cavity 201; wherein, the cylinder 121 is disposed within the receiving cavity 201. In order to ensure that the multiple frame edges 110 can contact the lower high-temperature cloth 232 disposed on the conveying assembly 220, in this embodiment, the distance between the frame edges 110 and the base plate 221 should be less than the stroke of the piston 122, so as to avoid the multiple frame edges 110 having a certain distance between them and the conveying assembly 220 when they descend to the lowest point.

[0067] Based on the above, since this embodiment has multiple parallel and spaced short sides 112 to form multiple accommodating cavities 101, the number of telescopic members 120 in this embodiment is multiple, and each telescopic member 120 is set at the connection between a short side 112 and a long side 111 to ensure the stability of the photovoltaic laminate frame assembly 100.

[0068] In other embodiments, only four borders 110 can be set to enclose and form a receiving cavity 101. In this case, telescopic members 120 are set at the four corners, that is, a telescopic member 120 is connected at the connection of every two borders 110.

[0069] It should be noted that the telescopic component 120 in this embodiment is a pneumatic cylinder. When the pneumatic cylinder is pressed down by the laminating plate 210, the pressure inside the pneumatic cylinder is greater than the external pressure. After the laminating plate 210 leaves, the pneumatic cylinder will push back multiple frame 110s to lift the frame 110s and separate the laminated photovoltaic module 300 from the frame 110s.

[0070] In other embodiments, the telescopic member 120 may also adopt other telescopic structures, such as an electric telescopic rod.

[0071] In summary, this embodiment uses multiple frame borders 110 to enclose and form a receiving cavity 101 for housing the photovoltaic module 300. This ensures that the photovoltaic module 300 is located within a closed space during lamination, thereby restricting the flow range of the various structures of the photovoltaic module 300 and the adhesive, preventing edge delamination and adhesive overflow during lamination, and improving lamination quality. Furthermore, this embodiment uses a telescopic member 120 to connect the multiple frame borders 110, enabling movement of the frame borders 110. After lamination, the photovoltaic module 300 can be detached from the receiving cavity 101 via the telescopic member 120, achieving automatic placement and removal of the frame borders 110, reducing labor costs, and improving manufacturing efficiency.

[0072] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
