[0045] The assembly method of traditional photovoltaic modules usually connects adjacent sides in the frame through corner codes and inserts the photovoltaic laminate into the insertion cavity of the frame. In the assembly method of traditional photovoltaic modules, it is necessary to first connect part of the frame through corner codes and insert the photovoltaic laminate into the connected part of the frame. When installing the last section of the frame on the part of the frame that has already formed a connection with the photovoltaic laminate, it is usually necessary to strike or apply pressure to the frame to make it form a connection with other frames and the photovoltaic laminate. In this process, due to applying pressure to the frame, it is easy to cause the photovoltaic laminate to burst.

[0046] To solve the above problems, as shown in Figures 1 - 4 An embodiment of this application provides an assembly method for a photovoltaic module, including the following steps:

[0047] Provide a photovoltaic laminate 1, a clamping member 2, and a frame 3. The frame 3 has an enclosed frame structure. The frame 3 has a fixing part 31 for installing on a fixed bottom surface and an installation part 32 for installing the photovoltaic laminate 1. A caulking groove 33 and a card slot 34 are provided on the frame 3. The caulking groove 33 is located in the installation part 32. The installation part 32 has an installation position with an opening facing away from the fixing part 31, and the photovoltaic laminate 1 can be placed into the installation position from the opening side of the installation position;

[0048] Fill the caulking groove 33 with an adhesive;

[0049] Place the photovoltaic laminate 1 from the opening on the installation position of the installation part 32 and make the photovoltaic laminate 1 contact the adhesive;

[0050] Insert the clamping member 2 into the card slot 34 and make the clamping member 2 abut against the photovoltaic laminate 1 to fix the photovoltaic laminate 1 on the frame 3.

[0051] In the assembling method of the above photovoltaic module, first, a frame 3 in a surrounding frame structure is provided, and the frame 3 has an installation part 32 for installing the photovoltaic laminate 1. The installation part 32 has an installation position with an opening facing away from the fixing part 31. In the present application, the photovoltaic laminate 1 is directly placed into the installation position from the opening side of the installation position, and the photovoltaic laminate 1 is brought into contact with the adhesive in the glue filling groove 33. Then, the clamping member 2 is inserted into the clamping groove 34, and the clamping member 2 is brought into abutment with the photovoltaic laminate 1, so as to fix the photovoltaic laminate 1 on the frame 3. Compared with the traditional assembling method of connecting the photovoltaic laminate 1 and the frame 3 by inserting the photovoltaic laminate 1 into the insertion cavity of the frame 3, the assembling method of the photovoltaic module in the present application can reduce the risk of the photovoltaic laminate bursting during the assembling process.

[0052] In some embodiments, the glue filling groove 33 is filled with adhesive by a first glue coating device 4.

[0053] In some embodiments, before inserting the clamping member 2 into the clamping groove 34, the following steps are further included:

[0054] An adhesive is coated on the side surface of the photovoltaic laminate 1 for abutting against the clamping member 2.

[0055] In some embodiments, an adhesive is coated on the side surface of the photovoltaic laminate 1 for abutting against the clamping member 2 by a second glue coating device 5.

[0056] Referring again to Figure 1 As shown, in some embodiments, the frame 3 includes side plates 301, support plates 302, mounting plates 303, and bottom plates 304. The installation part 32 includes support plates 302, mounting plates 303, and part of the side plates 301. The fixing part 31 includes the bottom plate 304. The support plates 302 and the bottom plates 304 are spaced apart on the side plates 301. The mounting plates 303 are arranged on the surface of the support plates 302 away from the bottom plates 304. The surface of the mounting plate 303 away from the bottom plate 304 is used to place the photovoltaic laminate 1.

[0057] The above embodiments show an implementable form of the frame 3. The photovoltaic laminate 1 is supported by the mounting plate 303 arranged on the surface of the support plate 302 away from the bottom plate 304, and the clamping member 2 is installed through the clamping groove 34 to fix the photovoltaic laminate 1 on the frame 3. It can be understood that Figure 1 is a sectional view along the height direction of the frame 3. The frame 3 with the above structure facilitates placing the photovoltaic laminate 1 in the installation position and is convenient for assembling the photovoltaic module.

[0058] In some of these embodiments, the frame 3 further includes a partition plate 305. The partition plate 305 is disposed on the surface of the support plate 302 away from the bottom plate 304 and is located between the side plate 301 and the mounting plate 303. The partition plate 305, the support plate 302, and the mounting plate 303 enclose a glue filling groove 33.

[0059] In the frame 3 having the partition plate 305, the partition plate 305, the support plate 302, and the mounting plate 303 can not only enclose the glue filling groove 33, but also facilitate the contact between the photovoltaic laminate 1 and the adhesive when the photovoltaic laminate 1 is placed on the mounting plate 303. At the same time, the top surface or side surface of the partition plate 305 can abut against the photovoltaic laminate 1 to increase the supporting effect on the photovoltaic laminate 1.

[0060] Refer to Figure 1 As shown, in some of these embodiments, the partition plate 305, the support plate 302, and the side plate 301 enclose an overflow glue groove 35. The clamping groove 34 is disposed on the side plate 301.

[0061] Refer to Figure 5 As shown, in some of these embodiments, the partition plate 305, the support plate 302, and the side plate 301 enclose a clamping groove 34.

[0062] Refer to Figure 6 As shown, in some of these embodiments, the frame 3 includes a plurality of connecting members 320 and a plurality of main body members 310. The plurality of main body members 310 are sequentially connected by the connecting members 320. The two side surfaces of the main body member 310 along its length direction are first abutting surfaces 311, and each first abutting surface 311 is an inclined surface, so that the outer length of the main body member 310 is greater than the inner length.

[0063] Refer to Figure 6 、 Figure 7 As shown, when the above-mentioned frame 3 is assembled, the connecting member 320 can be bent so that the relatively arranged first abutting surfaces 311 of the adjacent main body members 310 move towards each other until they abut, and the plurality of main body members 310 are connected end to end, thereby enclosing a frame 3 with a closed-loop structure. After the main body members 310 are enclosed, the first abutting surfaces 311 of the adjacent two main body members 310 abut against each other. That is, each main body member 310 in the frame 3 can form a frame 3 with an enclosed frame structure by bending the connecting member 320. The above-mentioned frame 3 can be formed by folding, and the assembly process is simple. Thus, a frame 3 with an enclosed frame structure is first formed, and then the photovoltaic laminate 1 is installed.

[0064] It can be understood that the inner side of the main body member 310 refers to the side where the frame 3 cooperates with the photovoltaic laminate 1 after the main body members 310 are enclosed, and the outer side of the main body member 310 refers to the side where the frame 3 is away from the photovoltaic laminate 1 after the main body members 310 are enclosed, that is, the outermost side in the photovoltaic module.

[0065] It can be understood that each first abutting surface 311 is an inclined surface, such that the outer length of the main body member 310 is greater than the inner length, enabling each main body member 310 to be folded inwards, thereby enclosing a frame 3 with a closed-loop structure.

[0066] Referring again to Figure 6 as shown, by way of example, Figure 1 the direction A in Figure 1 is the length direction of the main body member 310. The direction B in Figure 1 is perpendicular to the plane of the paper, and by way of example,

[0067] In some embodiments, the connecting member 320 is connected to the relatively arranged first abutting surfaces 311 of two adjacent main body members 310.

[0068] In some embodiments, the connecting member 320 is disposed on the first abutting surface 311 and near the outer side of the main body member 310. The connecting member 320 is disposed on the first abutting surface 311 and near the outer side of the main body member 310, facilitating the inward folding of each main body member 310.

[0069] In some embodiments, the frame 3 includes three connecting members 320 and four main body members 310.

[0070] Taking the frame 3 with the above structure as a specific example, including three connecting members 320 and four main body members 310, can enclose and form a square frame 3. When assembling the above frame 3, the connecting member 320 can be bent in sequence, so that the first abutting surfaces 311 of two adjacent main body members 310 abut against each other, thereby forming three corners of the enclosed frame 3. At the same time, through the bending of the connecting member 320, the three corners of the formed frame 3 can be arc-shaped corners, which can increase the aesthetics of the frame 3 while reducing the bumps at the right-angle corners. Finally, the main body members 310 arranged in sequence along the length direction of the main body member 310 are connected end to end, that is, the two first abutting surfaces 311 that are farthest apart are abutted against each other to form a completely enclosed frame 3.

[0071] In some embodiments, each first abutting surface 311 of each main body member 310 is the same.

[0072] In some embodiments, when each main body member 310 is arranged in sequence along its length direction, each first abutting surface 311 forms a 45° angle with the length direction of the main body member 310.

[0073] Referring to Figure 8As shown, in some of the embodiments, the main body member 310 includes a set of protrusions 312 and recesses 313 that can cooperate with each other. At least one set of protrusions 312 and recesses 313 are provided on a set of first abutting surfaces 311 that cooperate with each other. After the main body members 310 are enclosed, each protrusion 312 is respectively clamped within a recess 313.

[0074] If the first abutting surface 311 is a smooth surface without protrusions 312 or recesses 313, in the enclosed frame 3, when adjacent main body members 310 are misaligned and stressed, it is easy to cause deformation and separation between adjacent main body members 310, thus causing the frame 3 to fail. By providing the cooperating protrusions 312 and recesses 313 on the first abutting surface 311, the firmness after enclosure between adjacent main body members 310 can be increased, and the risk of deformation and separation between adjacent main body members 310 can be reduced. It can be understood that only protrusions 312 or recesses 313 can be provided on a single first abutting surface 311, or both protrusions 312 and recesses 313 can be provided at the same time. If only protrusions 312 are provided on a first abutting surface 311, then at the corresponding position on the first abutting surface 311 that abuts against it after enclosure, the same number of recesses 313 are provided. If both protrusions 312 and recesses 313 are provided on a first abutting surface 311, then the recesses 313 and protrusions 312 are provided in one-to-one correspondence on the first abutting surface 311 that abuts against it after enclosure.

[0075] It can be understood that the shape of the protrusion 312 can be a regular shape or an irregular shape, and the shape of the recess 313 is adapted to the corresponding protrusion 312.

[0076] In some of the embodiments, multiple sets of protrusions 312 and recesses 313 are provided on each set of first abutting surfaces 311 that cooperate with each other. The protrusions 312 and recesses 313 are provided at intervals on each first abutting surface 311. The protrusions 312 and recesses 313 being provided at intervals on each first abutting surface 311 can further increase the fixing effect between adjacent main body members 310.

[0077] In some of the embodiments, on a single first abutting surface 311, the total number of protrusions 312 and recesses 313 is from 2 to 10. Optionally, on a single first abutting surface 311, the total number of protrusions 312 and recesses 313 is 2, 3, 4, 5, 6, 7, 8, 9, or 10.

[0078] In some of the embodiments, on a single first abutting surface 311, the protrusions 312 and recesses 313 are arranged alternately.

[0079] In some of these embodiments, the connecting member 320 and the main body member 310 are integrally formed.

[0080] It can be understood that the frame 3 of the present application can be integrally formed to obtain a long strip-shaped frame preform, and then the frame preform is cut to form the first abutting surface 311, so as to obtain the frame 3 that can be assembled by folding.

[0081] In some of these embodiments, the surface of the connecting member 320 facing the inner side of the main body member 310 is an arc surface.

[0082] The surface of the connecting member 320 facing the inner side of the main body member 310 is an arc surface, which facilitates bending the connecting member 320 to form a frame 3 with an arc-shaped corner at the corner.

[0083] Refer to Figure 7 As shown, in some of these embodiments, the method for enclosing the frame 3 includes the following steps:

[0084] Bend each connecting member 320 so that each main body member 310 abuts against each other through the first abutting surface 311, and make multiple main body members 310 enclose a frame structure;

[0085] Use the joint buckle 330 to connect and fix the two main body members 310 at the joint position.

[0086] Refer to Figures 9 - 11 As shown, in some of these embodiments, the joint buckle 330 includes a buckle main body portion 331 and a buckle abutting portion 332. The buckle abutting portion 332 is located at one end of the buckle main body portion 331. The buckle abutting portion 332 has two second abutting surfaces 3321, and the two second abutting surfaces 3321 are respectively used to abut against the two main body members 310 at the joint position. Along the direction gradually away from the buckle main body portion 331, the width of the buckle abutting portion 332 gradually decreases. A through groove 333 is provided on the joint buckle 330 and opens at its bottom surface, and the through groove 333 penetrates through the buckle main body portion 331 and the buckle abutting portion 332 along the length direction of the buckle main body portion 331. Guide rails 307 are provided on both of the two main body members 310 at the joint position.

[0087] In some of these embodiments, using the joint buckle 330 to connect and fix the two main body members 310 at the joint position includes the following steps:

[0088] Set the two guide rails 307 in the through groove 333 at the same time;

[0089] Move the joint buckle 330 on the guide rail 307 until the two second abutting surfaces 3321 respectively abut against the inner side surfaces of the two main body members 310 at the joint position.

[0090] Refer to again Figure 10 、 Figure 11As shown, by way of example, Figure 10 , Figure 11 in Figure 10 and Figure 11 , the X direction is the length direction of the buckle main body 331, the Y direction is the thickness direction of the buckle main body 331, and the Z direction is the width direction of the buckle main body 331.

[0091] In some embodiments, the two second abutting surfaces 3321 form a 45° angle.

[0092] The two second abutting surfaces 3321 forming a 45° angle facilitates the abutment of the buckle main body 331 against the right-angle corner in the frame 3.

[0093] In some embodiments, the two second abutting surfaces 3321 are connected on the side away from the buckle main body 331 to form a tip structure. The buckle abutting portion 332 with the above structure can be completely attached to the corner of the frame 3, achieving a better fixing effect.

[0094] In some embodiments, the through slot 333 includes a relief portion 3331 and a guiding portion 3332. The guiding portion 3332 opens at the bottom surface. The width of the relief portion 3331 is greater than the width of the guiding portion 3332.

[0095] When the joint buckle 330 with the above structure of the through slot 333 is in use, it can pass through a component provided in the frame 3 and extending along the width direction of the relief portion 3331, and place the component in the relief portion 3331, which can provide a downward limiting effect on the joint buckle 330 and improve the fixing effect of the joint buckle 330.

[0096] In some embodiments, the width direction of the relief portion 3331 is perpendicular to the length direction of the buckle main body 331.

[0097] In some embodiments, the joint buckle 330 further includes a reinforcement portion 334. The reinforcement portion 334 is provided on the surface of the buckle abutting portion 332 opposite to the bottom surface. The reinforcement portion 334 has two third abutting surfaces 3341, and the two third abutting surfaces 3341 are flush with the two second abutting surfaces 3321 respectively.

[0098] By abutting the two third abutting surfaces 3341 against the adjacent sides in the frame 3, the contact area between the joint buckle 330 and the adjacent sides in the frame 3 can be increased, enabling the joint buckle 330 to have a better fixing effect.

[0099] In some embodiments, the through slot 333 includes a relief portion 3331 and a guiding portion 3332. Compared with the relief portion 3331, the guiding portion 3332 is closer to the slot opening of the through slot 333. The width of the guiding portion 3332 is greater than the width of the relief portion 3331.

[0100] In some embodiments, the guide rail member 307 includes a first sub-portion and a second sub-portion. The first sub-portion is disposed on the surface of the bottom plate 304 facing the support plate 302. The second sub-portion is disposed on the side of the first sub-portion, and the second sub-portion and the bottom plate 304 are spaced apart. When the guide rail member 307 is engaged with the through slot 333, the two first sub-portions pass through the guide portion 3332 and extend into the yielding portion 3331. Both the second sub-portions are disposed in the yielding portion 3331.

[0101] The guide rail member 307 having the above structure can be adapted to the through groove 333 including the yielding portion 3331 and the guide portion 3332. When the guide rail members 307 of the two adjacent main members 310 are connected through the joint buckle 330, the two second sub-parts located in the yielding portion 3331 can provide a downward limiting effect on the joint buckle 330, thereby improving the fixing effect of the joint buckle 330.

[0102] In some embodiments, the frame 3 further includes a stopper 3071. The stopper 3071 is disposed on the surface of the guide rail 307 away from the bottom plate 304. When the guide rail 307 is engaged with the through slot 333, the stopper 3071 abuts against one end of the buckle body 331 away from the buckle abutting portion 332.

[0103] Another embodiment of the present application provides a photovoltaic assembly, which is assembled by any of the above-mentioned photovoltaic assembly assembly methods, including a photovoltaic laminate 1, a clamping member 2 and a frame 3, wherein the frame 3 is an enclosed frame structure, the frame 3 has a fixing portion 31 for mounting on a fixed bottom surface and a mounting portion 32 for mounting the photovoltaic laminate 1, and the frame 3 is provided with a glue filling groove 33 and a clamping groove 34, the glue filling groove 33 is located in the mounting portion 32, and the glue filling groove 33 is filled with adhesive. The mounting portion 32 has an installation position with an opening facing away from the fixing portion 31, and the photovoltaic laminate 1 can be placed in the installation position from the opening side of the installation position. The photovoltaic laminate 1 is arranged on the installation position of the mounting portion 32, and the photovoltaic laminate 1 is in contact with the adhesive. The clamping member 2 is inserted into the clamping groove 34, and the clamping member 2 abuts against the photovoltaic laminate 1.

[0104] In some embodiments, the main body 310 further includes a connecting plate 306. One side of the connecting plate 306 is connected to the supporting plate 302, and the other side is connected to the bottom plate 304. The connecting plate 306 is spaced apart and arranged opposite to the side plate 301. The connecting plate 306, the bottom plate 304, the side plate 301 and the supporting plate 302 enclose a molding cavity 36.

[0105] In some embodiments, the maximum height of the partition plate 305 from the support plate 302 is greater than or equal to the maximum height of the mounting plate 303 from the support plate 302 .

[0106] Reference Figure 5 As shown, illustratively, Figure 5The maximum height of the partition plate 305 from the support plate 302 is H1, and the maximum height of the mounting plate 303 from the support plate 302 is H2. When the maximum height of the partition plate 305 from the support plate 302 is equal to the maximum height of the mounting plate 303 from the support plate 302, the back panel 11 of the photovoltaic laminate 1 can be supported and positioned by the surface of the partition plate 305 away from the support plate 302. When the maximum height of the partition plate 305 from the support plate 302 is greater than the maximum height of the mounting plate 303 from the support plate 302, the side surface of the back panel 11 of the photovoltaic laminate 1 abuts against the side surface of the partition plate 305.

[0107] In some embodiments, the side surface of the partition plate 305 has a recessed area that matches the side surface of the back panel 11 of the photovoltaic laminate 1 to abut against the side surface of the back panel 11.

[0108] In some embodiments, the mounting plate 303 includes a third sub - part and a fourth sub - part. The third sub - part is disposed on the support plate 302 and protrudes from the surface of the support plate 302 away from the bottom plate 304. The partition plate 305, the support plate 302 and the third sub - part enclose a glue - filling groove 33. The fourth sub - part is connected to the third sub - part and extends in a direction away from the partition plate 305. The surface of the fourth sub - part away from the support plate 302 is used to support the photovoltaic laminate 1.

[0109] Another embodiment of the present application provides a photovoltaic module, including the frame 3 of any one of the above and a photovoltaic laminate 1. The frame 3 surrounds the outer periphery of the photovoltaic laminate 1.

[0110] See Figure 1 、 Figure 5 As shown, the photovoltaic laminate 1 is fixed by the mounting plate 303, the partition plate 305 and the clamping member 2. Specifically, the back panel 11 of the photovoltaic laminate 1 abuts against the surface of the mounting plate 303 away from the support plate 302, and the side surface of the back panel 11 of the photovoltaic laminate 1 abuts against the side surface of the partition plate 305. The side surface of the partition plate 305 has a recessed area that matches the side surface of the back panel 11 of the photovoltaic laminate 1 to accommodate the side surface of the back panel 11. The side surface of the front panel 12 of the photovoltaic laminate 1 abuts against the side surface of the clamping member 2. One side of the clamping member 2 away from the support plate 302 extends towards the photovoltaic laminate 1, and the side surface of the clamping member 2 matches the side surface of the front panel 12 of the photovoltaic laminate 1.

[0111] In some embodiments, the distance between the mounting plate 303 and the surface of the clamping member 2 away from the support plate 302 is less than or equal to the thickness of the photovoltaic laminate 1.

[0112] Refer to Figure 8 As shown, Figure 8Among them, H3 is the distance between the mounting plate 303 and the surface of the clamping member 2 away from the support plate 302. When the distance between the mounting plate 303 and the surface of the clamping member 2 away from the support plate 302 is equal to the thickness of the photovoltaic laminate 1, the surface of the clamping member 2 away from the support plate 302 is lower than or flush with the upper surface of the front panel 12 of the photovoltaic laminate 1, which can reduce the dust accumulation on the front side of the photovoltaic laminate 1.

[0113] In some embodiments, the photovoltaic laminate 1 includes a front panel 12, a first adhesive layer, solar cells, a second adhesive layer, and a back panel 11 stacked. A first adhesive layer is disposed between the front panel 12 and the solar cells, and a second adhesive layer is disposed between the solar cells and the back panel 11. At least one side edge of the back panel 11 protrudes from the corresponding side edge of the front panel 12.

[0114] The above photovoltaic laminate 1 can be applied to the frame 3 without an A side to reduce the dust accumulation of the photovoltaic module. At the same time, the part of the back panel 11 protruding from the edge of the front panel 12 can also provide a stress point. By applying pressure to the surface of the back panel 11 exposed from the front panel 12, the fixing effect on the photovoltaic laminate 1 can be improved, and the airborne strength can be improved.

[0115] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
