It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or part from another element, component, region, layer, or part. Thus, without departing from the teachings of the present application, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part. And when discussing the second element, component, region, layer, or part, it does not mean that there must be a first element, component, region, layer, or part in the present application.

[0045] In the present application, unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0046] It should be noted that the terms "first", "second", etc. in the specification, claims, and above-mentioned drawings of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

Unless otherwise specified, when the numerical interval only refers to the integers within the numerical interval, it includes the two endpoint integers of the numerical range, as well as each integer between the two endpoints, which is equivalent to directly listing each integer. When multiple numerical ranges are provided to describe features or characteristics, these numerical ranges can be combined. In other words, unless otherwise specified, the numerical ranges disclosed in this application should be understood to include any and all sub-ranges subsumed therein. The "numerical value" in the numerical interval can be any quantitative value, such as a number, a percentage, a ratio, etc. The "numerical interval" allows for a broad inclusion of quantitative intervals such as percentage intervals, ratio intervals, ratio value intervals, etc.

[0048] Next, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in various different forms and should not be construed as being limited only to the embodiments described herein.

[0049] Please refer to Figures 1 to 3 , an embodiment of the present application provides a lamination frame, which includes a first frame edge 10, a second frame edge 20, a third frame edge 30, and a first anti-fouling cloth 51. The following is a detailed description:

[0050] The first frame edge 10 includes a first side 11, a second side 12 and a third side 13 oppositely arranged at both ends of the first side 11. The second side 12 and the third side 13 are connected to different ends of the first side 11 and extend in the same direction.

[0051] The second frame edge 20 includes a fourth side 24 and a fifth side 25. The fourth side 24 is used to connect to the end of the second side 12 away from the first side 11, and the fourth side 24 and the second side 12 are on the same straight line; the fifth side 25 is used to connect to the end of the third side 13 away from the first side 11, and the fifth side 25 and the third side 13 are on the same straight line.

[0052] The third frame edge 30 includes a sixth side 36, a seventh side 37 and an eighth side 38 oppositely arranged at both ends of the sixth side 36. Among them, the seventh side 37 is connected to the second side 12 through the fourth side 24, and the eighth side 38 is connected to the third side 13 through the fifth side 25, so that the first frame edge 10, the second frame edge 20, and the third frame edge 30 enclose to form a frame.

[0053] The first anti-fouling cloth 51 covers the first side of the frame. The first anti-fouling cloth 51 can be used to carry the battery cells to be laminated and prevent dirt and impurities from entering the frame. The frame is used to restrict the movement of the battery cells in the horizontal direction.

[0054] Among them, the heights of the first frame edge 10, the second frame edge 20, and the third frame edge 30 along the normal direction perpendicular to the frame are different from each other.

[0055] Specifically, the first frame edge 10, the second frame edge 20, and the third frame edge 30 can be connected to each other by welding and enclose to form a frame with openings on both sides. The first anti-fouling cloth 51 closes one opening of the frame to form a receiving groove, and the receiving groove can be used to carry the battery cells for entering the lamination process. Among them, since the heights of the first frame edge 10, the second frame edge 20, and the third frame edge 30 along the normal direction perpendicular to the frame are different, that is, the corresponding areas of the first frame edge 10, the second frame edge 20, and the third frame edge 30 can be respectively used to place battery cells of different models and thicknesses, so as to send the battery cells carrying multiple different models and thicknesses into the laminator for lamination at the same time, improving the lamination efficiency.

[0056] Specifically, in this embodiment, the first frame edge 10 can correspond to a first receiving groove (not marked in the figure), the second frame edge 20 can correspond to a second receiving groove (not marked in the figure), and the third frame edge 30 can correspond to a third receiving groove (not marked in the figure). The three receiving grooves with different heights can respectively place battery cells of different models and thicknesses. Preferably, the projections of the first receiving groove, the second receiving groove, and the third receiving groove are all rectangular, and the frame formed by enclosing the first frame edge 10, the second frame edge 20, and the third frame edge 30 is rectangular. It can be understood that most photovoltaic modules and battery cells are designed based on rectangles. The rectangular receiving grooves and the rectangular frame are convenient for docking with the rectangular battery cells and photovoltaic modules, and are convenient for fixing and positioning the battery cells and photovoltaic modules in the receiving grooves and the frame. In addition, the lengths and angles of the sides of the rectangular frame are easy to measure and cut, which is convenient for processing and assembly.

[0057] Further, in an alternative embodiment, the height of the first frame edge 10 along the normal direction perpendicular to the frame is greater than the height of the second frame edge 20 along the normal direction perpendicular to the frame.

[0058] The height of the second frame edge 20 along the normal direction perpendicular to the frame is greater than the height of the third frame edge 30 along the normal direction perpendicular to the frame.

[0059] That is, the heights of the first frame edge 10, the second frame edge 20, and the third frame edge 30 decrease in sequence, and the three frame edges form a stepped shape on the side. The receiving grooves corresponding to different frame edges can be used to accommodate battery cells matching the height of the frame edges for lamination. When the lamination device does not contact the lamination frame, the lamination device laminates the battery cells normally. When the lamination device is pressed down to a certain extent, the thickness of the frame edge can be used to offset the damage of the lamination device to the battery cells, while ensuring the accuracy of the lamination thickness.

[0060] Exemplarily, the height of the first frame edge 10 in the direction normal to the frame is 6 mm, the height of the second frame edge 20 in the direction normal to the frame is 5 mm, and the height of the third frame edge 30 in the direction normal to the frame is 4 mm. The first accommodation groove corresponding to the first frame edge 10 can be used to accommodate a solar cell with a predetermined thickness (i.e., the ideal thickness after lamination) of 6 mm, the second accommodation groove corresponding to the second frame edge 20 can be used to accommodate a solar cell with a predetermined thickness of 5 mm, and the third accommodation groove corresponding to the third frame edge 30 can be used to accommodate a solar cell with a predetermined thickness of 4 mm. During lamination, the lamination device laminates the solar cell in the thickness direction until it abuts against the first frame edge 10. The first frame edge 10 can be used to position the height of lamination to prevent the lamination device from over-laminating and damaging the solar cell. The frame edges with decreasing heights in sequence facilitate the confirmation of the orientation of the entire frame, which is convenient for the placement of the lamination frame and the insertion of the solar cell into the lamination frame.

[0061] In other embodiments, the heights of the first frame edge 10, the second frame edge 20, and the third frame edge 30 may also have other relationships. For example, the height of the second frame edge 20 is greater than the height of the first frame edge 10, and the height of the first frame edge 10 is greater than the height of the third frame edge 30; or the heights of the third frame edge 30, the second frame edge 20, and the first frame edge 10 decrease in sequence.

[0062] In an alternative embodiment, please refer to Figure 2 and Figure 3 , for the convenience of assembling the first frame edge 10 and the second frame edge 20, a first coordination groove 121 is provided at the end of the second side 12 facing the fourth side 24, and a first coordination block 241 is provided at the end of the fourth side 24 facing the second side 12. The first coordination block 241 is clamped in the first coordination groove 121; a second coordination groove is provided at the end of the third side 13 facing the fifth side 25, and a second coordination block is provided at the end of the fifth side 25 facing the third side 13. The second coordination block is clamped in the second coordination groove.

[0063] When assembling the lamination frame, the end of the fourth side 24 with the first coordination block 241 can be clamped and installed with the first coordination groove 121 of the second side 12, and the end of the fifth side 25 with the second coordination block can be clamped and installed with the second coordination groove of the third side 13, so that the first frame edge 10 and the second frame edge 20 are fitted and connected, which can significantly improve the overall stability and strength of the frame. Moreover, the clamping and assembling method of the first coordination block 241 and the first coordination groove 121 also facilitates the assembly and alignment of the first frame edge 10 and the second frame edge 20, reducing the difficulty and time of manual alignment.

[0064] Similarly, the third frame edge 30 can also be fitted and connected with the second frame edge 20 through a similar structure, and its functions and effects are similar to those of the fitting of the first frame edge 10 and the second frame edge 20, which will not be elaborated here.

[0065] The fitting connection between the first frame edge 10 and the second frame edge 20 facilitates the disassembly and assembly of the two, so that the first frame edge 10 or the second frame edge 20 can be replaced with a frame edge of a higher or lower height according to the process requirements, enabling the lamination frame to adapt to battery wafers of various thicknesses and improving the reusability of the lamination frame.

[0066] In addition, the fitting connection between the first frame edge 10 and the second frame edge 20 can also be used as a pre - process for welding and fixing. That is, after the first frame edge 10 and the second frame edge 20 are fitted and connected, they are kept in a relatively stable connection, and then the first frame edge 10 and the second frame edge 20 are welded and fixed, avoiding the situation of misalignment and deviation in the connection between the first frame edge 10 and the second frame edge 20 caused by unstable connection during welding.

[0067] In one embodiment, the first coordination block 241 and the first coordination groove 121 can be in interference fit, so that the first frame edge 10 and the second frame edge 20 form a highly tight connection, improving the overall strength and stability of the frame.

[0068] Furthermore, in this embodiment, a first adsorption block 243 is provided at the end of the first coordination block 241 away from the fourth side 24, and a second adsorption block 122 corresponding to the first adsorption block 243 is provided at the bottom of the first coordination groove 121. The first adsorption block 243 and the second adsorption block 122 are magnetically connected.

[0069] The magnetic connection between the first adsorption block 243 and the second adsorption block 122 provides additional connection strength, further enhancing the connection stability between the first frame edge 10 and the second frame edge 20. Magnetic adsorption is not easily affected by pressure and temperature, so that the first frame edge 10 and the second frame edge 20 can maintain the connection under high - pressure and high - temperature environments, preventing loosening and displacement.

[0070] Specifically, when assembling the first frame edge 10 and the second frame edge 20, the mutual adsorption of the first adsorption block 243 and the second adsorption block 122 can automatically align the first coordination block 241 and the first coordination groove 121, thereby reducing the human assembly error and improving the assembly accuracy and consistency. When the first adsorption block 243 and the second adsorption block 122 are adsorbed and connected, they can also provide an immediate feedback signal to the worker, indicating that the connection has been successful and stable. The immediate feedback signal enables the worker not to need additional inspection or confirmation, and can get the feedback immediately after each connection is completed, and can directly proceed to the next step (such as welding, or continue to assemble with other frame edges), improving the assembly efficiency of the lamination frame.

[0071] Similarly, the third frame edge 30 can also be adsorbed and connected to the second frame edge 20 through a similar structure, and its functions and effects are similar to the connection between the first frame edge 10 and the second frame edge 20, which will not be elaborated here.

[0072] In an alternative embodiment, a first snap spring is provided on the inner wall of the first coordination groove 121, and a first snap groove (not labeled in the figure) matching the shape of the end of the first snap spring is provided on the first coordination block 241.

[0073] When assembling the first frame edge 10 and the second frame edge 20, the first coordination block 241 at the end of the fourth side 24 is pushed towards the first coordination groove 121 at the end of the second side 12. During the pushing process, the first snap spring on the inner wall of the first coordination groove 121 is squeezed by the first coordination block 241 until the first coordination block 241 is pushed to a predetermined position. At this time, the first snap groove on the first coordination block 241 corresponds to the first snap spring, and the first snap spring releases and returns to its original shape and snaps into the first snap groove to complete the coordination.

[0074] After the first snap spring and the first snap groove are coordinated, they can be locked with each other, and the first snap spring can also prevent it from disengaging from the first snap groove after returning to its original shape, further enhancing the stability of the connection between the first frame edge 10 and the second frame edge 20. Moreover, the first snap spring can provide an immediate feedback signal when released from the squeezed state, and its function is similar to that of the above-mentioned first adsorption block 243 and second adsorption block 122.

[0075] Specifically, in this embodiment, the first snap spring includes an elastic portion 127 and a first snap block 129. The first end of the elastic portion 127 is fixed to the inner side wall of the first coordination groove 121, and the first snap block 129 is fixed to the second end of the elastic portion 127. The shape of the first snap groove matches the outer edge of the first snap block 129.

[0076] During the process of pushing the first coordination block 241 at the end of the fourth side 24 towards the first coordination groove 121 at the end of the second side 12, the elastic portion 127 is compressed until the first coordination block 241 is pushed to a predetermined position. At this time, the first snap spring moves to the position of the first snap groove, and the elastic portion 127 is no longer compressed. After the elastic portion 127 is released, the shape of the first snap groove matches the outer edge of the first snap block 129, so that the first snap block 129 snaps into the first snap groove to complete the installation.

[0077] Specifically, the elastic portion 127 can be a structure such as a spring or a spring sheet. The first snap block 129 can be a semi-circular protrusion. One end of the elastic portion 127 is connected to the inner wall of the first coordination groove 121, and the other end is connected to one side of the plane of the semi-circular protrusion. The arc surface of the semi-circular protrusion is used for coordination with the first snap groove, and the first snap groove can be set as an arc groove corresponding to the semi-circular protrusion.

[0078] In an alternative embodiment, a first coordination groove 121 at the end of the second side 12 can be configured to simultaneously accommodate a first adsorption block 243 and a first snap spring, and a first coordination block 241 at the end of the fourth side 24 can be configured to simultaneously accommodate a second adsorption block 122 and a first card slot, so that the second side 12 and the fourth side 24 can be positioned and connected simultaneously through adsorption and clamping, ensuring the stability of their connection, facilitating assembly and disassembly, and improving the freedom of use.

[0079] It can be understood that the third side 13 and the fifth side 25 can also be connected to each other through the same or similar structures as described above.

[0080] The third frame side 30 can also be connected to the second frame side 20 through a similar structure, and its function and effect are similar to the connection between the first frame side 10 and the second frame side 20, which will not be elaborated here.

[0081] In an alternative embodiment, please refer to Figure 1 and Figure 2 , and refer to Figure 4 . The lamination frame further includes a first partition frame 41 and a second partition frame 42. The first partition frame 41 spans between the fourth side 24 and the fifth side 25 and is close to the first side 11; the second partition frame 42 spans between the seventh side 37 and the eighth side 38 and is close to the first side 11.

[0082] The first partition frame 41 can be used to cooperate with the first frame side 10 to enclose a first frame, and the first frame corresponds to a first accommodation groove for accommodating a solar cell that matches the height of the first frame side 10. The first partition frame 41 can prevent the solar cell in the first accommodation groove from shifting to an adjacent accommodation groove.

[0083] Similarly, the first partition frame 41, the second frame side 20, and the second partition frame 42 cooperate to enclose a second frame, and the second frame corresponds to a second accommodation groove. The second partition frame 42 and the second frame side 20 cooperate to enclose a third frame, and the third frame corresponds to a third accommodation groove.

[0084] The first partition frame 41 is used to separate the first accommodation groove and the second accommodation groove, and the second partition frame 42 is used to separate the second accommodation groove and the third accommodation groove, so as to prevent the solar cells in the accommodation grooves from moving into other adjacent accommodation grooves due to external forces, thereby avoiding problems such as lamination rupture or substandard lamination.

[0085] Specifically, a first lapping block 411 is provided at the first end of the first partition frame 41. A first threaded hole 413 is formed in the first lapping block 411. A second lapping block 415 is provided at the second end of the first partition frame 41. A second threaded hole 417 is formed in the second lapping block 415. The first lapping block 411 is lapped on the fourth side 24. A bolt passes through the first threaded hole 413 and is screwed to the fourth side 24. The second lapping block 415 is lapped on the fifth side 25. A bolt passes through the second threaded hole 417 and is screwed to the fifth side 25, so that the first partition frame 41 is fixedly connected to the fourth side 24 and the fifth side 25.

[0086] Similarly, threaded holes can be formed at both ends of the second partition frame 42, and the second partition frame 42 can be fixedly connected to the seventh side 37 and the eighth side 38 respectively through bolts.

[0087] In an alternative embodiment, please refer to Figure 5 , the lamination frame further includes a second anti-fouling cloth 52. The second anti-fouling cloth 52 is connected to one side of the first anti-fouling cloth 51 and can be folded along the side connected to the first anti-fouling cloth 51 to cover or expose the second side of the frame surrounded by the first frame edge 10, the second frame edge 20, and the third frame edge 30.

[0088] After the battery cells are placed in the lamination frame, the second anti-fouling cloth 52 can be folded along the connection side with the first anti-fouling cloth 51 to cover the second side of the frame, so that the first anti-fouling cloth 51 supports the battery cells, the second anti-fouling cloth 52 covers the battery cells, and a closed space is formed in cooperation with the frame. The second anti-fouling cloth 52 covers the battery cells, which can prevent impurities and dirt from entering the frame during lamination and contaminating the battery cells.

[0089] Specifically, in this embodiment, both the first anti-fouling cloth 51 and the second anti-fouling cloth 52 can be tetrafluoro cloths to withstand the temperature during lamination and have good cleanliness. In other embodiments, the first anti-fouling cloth 51 and the second anti-fouling cloth 52 can also be Teflon cloths, etc.

[0090] In some embodiments, the second anti-fouling cloth 52 may not be connected to the first anti-fouling cloth 51. After the battery cells are placed in the frame, the second anti-fouling cloth 52 can be directly covered on the second side of the frame.

[0091] In an alternative embodiment, please refer to Figure 6, a notch is provided on the first side 11 so that the first side 11 is separated into a discontinuous first sub - side 111 and a second sub - side 112. The first frame side 10 further includes a first convex frame 19, and the first convex frame 19 includes: a first section 191, a second section 192, and a third section 193. Among them, one end of the first section 191 is connected to the end of the first sub - side 111 away from the second side 12 and extends away from the first sub - side 111; one end of the second section 192 is connected to the end of the second sub - side 112 away from the third side 13 and extends away from the second sub - side 112; the third section 193 is bridged between the first section 191 and the second section 192 and is away from the first side 11.

[0092] Specifically, the first convex frame 19 can be fixed to the notch of the first side 11 by welding.

[0093] The height of the first convex frame 19 in the direction normal to the frame can be the same as the height of the first frame side 10 in the direction normal to the frame, so that the first convex frame 19 serves as an extension of the first frame side 10. The first convex frame 19 can accommodate solar cells of corresponding height to increase the accommodating space of the first frame side 10.

[0094] Similarly, a notch can also be provided on the sixth side 36 so that the sixth side 36 is separated into two discontinuous sub - sides, and a second convex frame protruding outward is connected at the notch of the sixth side 36. The structure of the second convex frame can be similar to that of the first convex frame 19 or be mirror - set with the connection line between the mid - points of the fourth side 24 and the fifth side 25 as the axis.

[0095] In an alternative embodiment, please refer to Figure 1 , and refer to Figure 7 , the first side 11 is a hollow rectangular column. The hollow rectangular column includes opposite first side surface 113 and second side surface 114. The first side 11 further includes a reinforcing rod 115, and the reinforcing rod 115 is bridged between the first side surface 113 and the second side surface 114.

[0096] The hollow rectangular column has good bending and torsional resistance. While maintaining sufficient physical strength of the first side 11, it reduces the weight, facilitating transportation and use. Moreover, the hollow rectangular column reserves space for thermal expansion and contraction inside, reducing the influence of thermal stress on the first side 11.

[0097] In this embodiment, there can be multiple reinforcing rods 115. The multiple reinforcing rods 115 are evenly spaced along the length direction of the first side 11. Each reinforcing rod 115 is bridged inside the first side 11 and connects the first side surface 113 and the second side surface 114 of the first side 11 to provide internal support for the first side 11 and improve the anti - bending performance of the first side 11.

[0098] Specifically, the first side surface 113 and the second side surface 114 can be two side surfaces distributed along the gravity direction, that is, they can be the bottom surface and the top surface of the first edge 11.

[0099] In an embodiment, a wear-resistant layer 117 is further coated on the outer side of the first edge 11 to improve the durability of the first edge 11 and reduce the situation that the first edge 11 appears fragments due to bumps and frictions, thereby soiling the solar cell. In some embodiments, the material of the wear-resistant layer 117 may include polytetrafluoroethylene, polyurethane, etc.

[0100] The wear-resistant layer 117 can be coated on the outer surfaces of the first side surface 113 and the second side surface 114 of the first edge 11. In some embodiments, the wear-resistant layer 117 can also be coated on the four side surfaces of the first edge 11.

[0101] It should be noted that the other edges (the second edge 12, the third edge 13) of the first frame edge 10, any single edge of the second frame edge 20, and any single edge of the third frame edge 30 can have the same structure as the first edge 11, so as to improve the consistency of the frame and make the weight distribution of the entire frame uniform.

[0102] The lamination frame of the embodiment of the present application can be used to carry photovoltaic cells for lamination encapsulation. The photovoltaic cells can be assembled into a photovoltaic module. Multiple photovoltaic modules can be connected in a specific manner to form a photovoltaic system. The photovoltaic system can be further applied to photovoltaic power stations, such as ground power stations, rooftop power stations, and water surface power stations, and also includes various devices and apparatuses that utilize solar energy for power generation, such as user solar power supplies, solar street lamps, solar cars, and solar buildings. Of course, it can be understood that the application scenarios of the photovoltaic system are not limited to this, that is to say, the photovoltaic system can be applied in all fields that require solar power generation. Taking the photovoltaic power generation system network as an example, the photovoltaic system can include a photovoltaic array, a busbar box, and an inverter. The photovoltaic array can be an array combination of multiple photovoltaic modules. For example, multiple photovoltaic modules can form multiple photovoltaic arrays. The photovoltaic array is connected to the busbar box, and the busbar box can collect the current generated by the photovoltaic array. After the collected current flows through the inverter and is converted into alternating current required by the commercial power grid, it is connected to the commercial power grid to achieve solar power supply.

[0103] It should be noted that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. The orientation terms "inner" and "outer" refer to the inside and outside relative to the contour of each component itself. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will then be positioned as "below other devices or structures" or "beneath other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the relative spatial descriptions used herein.
