[0109] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0110] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0111] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
[0112] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0113] In the drawings of this document, directions X, Y and Z are perpendicular to each other, wherein direction Y is the direction from bottom to top.
[0114] The manufacturing method of photovoltaic modules in the prior art includes: first, processing four profiles separately, second, bonding the four processed profiles to the laminate in sequence, and connecting the four processed profiles to form a frame in sequence. In the process of removing the local structure of the profile, it is necessary to clamp the four profiles four times and unclamp them four times, which requires a long processing time. In the process of bonding the four processed profiles to the laminate in sequence, the four separately arranged profiles need to be positioned by the clamp with more degrees of freedom, making the positioning difficult. In the process of connecting the four processed profiles to form a frame in sequence, it is necessary to connect the four profiles four times, which requires a long fixed connection time.
[0115] In view of the above problems, an embodiment of the present application provides a method for manufacturing a photovoltaic module, and the method for manufacturing a photovoltaic module includes step S1, step S2, step S3, step S4 and step S5.
[0116] Step S1: removing local structures at both ends of the profile to form chamfer structures at both ends of the profile. Profile is defined as: a straight strip structure with a certain cross-sectional shape and size after metal is formed by plastic processing.
[0117] Please refer to Figure 1 The profile 02 shown in the figure may include a side structure edge 021 to be processed and a bottom structure edge 022 to be processed. The side structure edge 021 to be processed is used to abut the side of the photovoltaic laminate (not shown in the figure) after processing, and the bottom structure edge 022 to be processed is used to support the bottom surface of the photovoltaic laminate after processing, that is, the profile 02 can be used as a frame structure connected to the photovoltaic laminate after processing, and the profile 02 can protect and fix the photovoltaic laminate. The relevant content about the photovoltaic laminate will be introduced later.
[0118] Please refer to Figure 1 As shown, the profile 02 includes a first end 0221 and a second end 0222 that are arranged opposite to each other in the direction Z. The local structure can be removed at the first end 0221 of the bottom structure edge 022 to be processed to form a Figure 2 The chamfered structure 0223 is located at the first end 0221 of the bottom structure edge 022 to be processed. The local structure can also be removed at the second end 0222 of the bottom structure edge 022 to be processed to form a Figure 2 The chamfered structure 0223 is shown at the second end 0222 of the bottom structure edge 022 to be processed. Of course, it is also possible to choose to remove the local structure at the first end 0221 of the side structure edge 021 to be processed and the second end 0222 of the side structure edge 021 to be processed. The following content of the method for forming the chamfered structure 0223 in this article is mainly described by removing the local structure at the end of the bottom structure edge 022 to be processed as an example.
[0119] In addition, in step S1, a milling process, a cutting process or a punching process may be used to remove the local structure to form the required chamfer structure 0223. The cutting process may include mechanical cutting, laser cutting or electric spark cutting.
[0120] Furthermore, the chamfer angle of the chamfer structure 0223 can be 45°, which is convenient for forming a rectangular frame later. Alternatively, the chamfer angle of the chamfer structure 0223 can also be other acute angles other than 45°, which is convenient for forming a parallelogram frame later. The following content of this article mainly describes the chamfer angle of the chamfer structure 0223 as 45° as an example.
[0121] In addition, the edge of the chamfered structure 0223 may be a straight line edge, or the edge of the chamfered structure 0223 may include an arc edge and / or a fold line edge.
[0122] Step S2: removing a local structure between the two ends of the profile to form a notch structure between the two ends of the profile.
[0123] Please refer to Figure 1 The profile 02 shown in the figure can remove the local structure of the part between the first end 0221 and the second end 0222 in the bottom structure edge 022 to be processed, so as to form Figure 2 The notch structure 0224 shown is located at the edge 022 of the bottom structure to be processed.
[0124] In step S2, a milling process, a cutting process or a punching process may be used to remove the local structure to form the required notch structure 0224. The cutting process may include mechanical cutting, laser cutting or electric spark cutting.
[0125] In addition, if the profile 02 is subsequently used to form a quadrilateral frame, the number of the notch structures 0224 formed in step S2 can be three. The positions of the three notch structures 0224 in the direction Z can be changed so that the profile 02 can subsequently form a square frame or a rectangular frame. Of course, the number of the notch structures 0224 formed in step S2 can be one, and the processed profile 02 can subsequently be used to form a two-sided frame, and accordingly, the two-sided frame can be combined with other two-sided frames to form a quadrilateral frame; the number of the notch structures 0224 formed in step S2 can be two, and the processed profile 02 can subsequently be used to form a three-sided frame, and accordingly, the three-sided frame can be combined with other single-sided frames to form a quadrilateral frame. The subsequent content of this article mainly describes the same profile 02 being processed to form a quadrilateral frame as an example.
[0126] Furthermore, the included angle of the notch structure 0224 can be 90°, so that the profile 02 can subsequently form a rectangular frame (square frame or rectangular frame). Among them, the included angle of a part of the notch structure 0224 can also be an acute angle, and the included angle of another part of the notch structure 0224 can be an obtuse angle, so that the profile 02 can subsequently form a parallelogram frame. The following content of this article mainly describes the notch structure 0224 with an included angle of 90° as an example.
[0127] In addition, the edge of the notch structure 0224 may be a straight line edge, or the edge of the notch structure 0224 may include an arc edge and / or a fold line edge.
[0128] Step S3: bending the portion of the profile corresponding to the notch structure to enclose and form a frame.
[0129] Please refer to Figure 2 As shown, the portion of the side structure edge 021 to be processed corresponding to the notch structure 0224 in the direction Z can be bent to enclose and form a Figure 3 The frame 2 shown. Accordingly, the notch structure 0224 is closed. Since the tip of the notch structure 0224 is located at the connection between the side structure edge 021 to be processed and the bottom structure edge 022 to be processed, during the bending process, the parts of the bottom structure edge 022 to be processed located on both sides of the notch structure 0224 are less likely to be squeezed against each other.
[0130] The bending can be performed by a bending machine. Specifically, the bending machine can simultaneously apply force and torque to the structures on both sides of the same notch 0224 in the profile 02, so that the portion of the side structure edge 021 to be processed corresponding to the notch structure 0224 in the direction Z is bent. Alternatively, the bending machine can fix one side of the profile 02 located at the same notch 0224, and the bending machine can apply force and torque to the other side of the profile 02 located at the same notch 0224, so that the portion of the side structure edge 021 to be processed corresponding to the notch structure 0224 in the direction Z is bent. When the number of notch structures 0224 is three, the bending machine can simultaneously bend the three portions of the side structure edge 021 to be processed corresponding to the three notch structures 0224 in the direction Z, or the bending machine can sequentially bend the three portions of the side structure edge 021 to be processed corresponding to the three notch structures 0224 in the direction Z.
[0131] Step S4: Connect the two chamfered structures of the frame to fix the frame.
[0132] After the profile 02 is bent, the two chamfered structures 0223 of the profile 02 are free parts, so the two chamfered structures 0223 need to be connected together so that Figure 3 The frame 2 shown can be reliably maintained as a quadrilateral frame, and the Figure 3 The frame 2 shown can serve as a frame structure with relatively high structural strength, so that the frame 2 can better protect, support and fix the photovoltaic laminate.
[0133] The connection method includes at least one of welding, bonding, connection using fasteners and connection using angle brackets.
[0134] In addition, since the two parts of the side structure edge 021 to be processed corresponding to the two chamfered structures 0223 in direction Z also serve as free parts and can also be connected together, accordingly, the connection method can also include at least one of welding, bonding, connection using fasteners and connection using angle codes.
[0135] Furthermore, the specific connection method of the two chamfered structures 0223 may be the same as or different from the specific connection method of the two parts of the side structure edge 021 to be processed corresponding to the two chamfered structures 0223 in the direction Z.
[0136] In addition, when the frame 2 is a quadrilateral frame, the frame 2 includes a first sub-frame 2a, a second sub-frame 2b, a third sub-frame 2c and a fourth sub-frame 2d connected to each other, and the cross-sectional shape of the first sub-frame 2a, the cross-sectional shape of the second sub-frame 2b, the cross-sectional shape of the third sub-frame 2c and the cross-sectional shape of the fourth sub-frame 2d are the same. Figure 4 As shown, taking the cross section of the first sub-frame 2a as an example, the frame 2 includes a connected side structure edge 21 and a bottom structure edge 22. The side structure edge 021 to be processed forms the side structure edge 21 after being bent, and the bottom structure edge 022 to be processed forms the bottom structure edge 22 after the local structure is removed and bent. The subsequent content of this article also mainly introduces the frame 2 by taking the cross-sectional structure diagram of the first sub-frame 2a shown in the attached figure as an example.
[0137] Step S5: placing adhesive on the frame and / or the laminate to bond the frame and the laminate.
[0138] Please refer to Figure 4 and Figure 5 As shown, adhesive 3 may be placed on the bottom structure edge 22 of the frame 2 first, and then the laminate 1 (including the cell for converting light energy into electrical energy) may be placed on the adhesive 3, so that the bottom structure edge 22 is bonded to the laminate 1 through the adhesive 3 to form the photovoltaic module 10. Alternatively, adhesive 3 may be placed on the laminate 1 first, and then the laminate 1 is bonded to the bottom structure edge 22 through the adhesive 3. Alternatively, adhesive 3 may be placed on the bottom structure edge 22 and adhesive 3 may be placed on the laminate 1 respectively, and then the bottom structure edge 22 and the laminate 1 are bonded to each other through the adhesive 3. Alternatively, the bottom structure edge 22 and the laminate 1 may be brought close to each other in the direction Y and a space may be formed between them, and adhesive 3 may be placed in the space between the bottom structure edge 22 and the laminate 1.
[0139] The side structural edge 21 of the frame 2 may also be bonded to the side surface 13 of the laminate 1 (not shown in the figure).
[0140] In the manufacturing method of the photovoltaic module provided in the embodiment of the present application, a part of the profile 02 is processed for removal, and the number of clamping and un-clamping times required for the same profile 02 is less, and the required processing time is shorter; secondly, a frame 2 and a laminate 1 are bonded, and the frame 2 needs to be positioned with fewer degrees of freedom by the clamp, and the positioning difficulty of the frame 2 is lower; furthermore, the two free parts of the frame 2 are connected and fixed once, and the fixed connection time of the frame 2 is shorter.
[0141] To sum up, compared with the manufacturing method of photovoltaic components in the prior art, the manufacturing method of photovoltaic components provided in the embodiment of the present application has the advantages of low manufacturing difficulty and short manufacturing time, that is, the manufacturing method of photovoltaic components provided in the present application can improve the production efficiency of photovoltaic components 10.
[0142] The introduction of the manufacturing method of the photovoltaic module of the embodiment of the present application is mainly based on the profile or frame with an L-shaped cross-section. Of course, the manufacturing method of the photovoltaic module of the embodiment of the present application is also applicable to profiles or frames with other cross-sectional shapes.
[0143] The method for manufacturing a photovoltaic module in the embodiment of the present application does not limit the order of step S1 and step S2. Step S1 can be implemented before step S2, or step S2 can be implemented before step S1. Alternatively, step S1 and step S2 can be implemented simultaneously, at least step S1 and step S2 need to be implemented before step S3.
[0144] The order of step S4 and step S5 is related to the cross-sectional shape of profile 02. If the cross-sectional shape of profile 02 is as follows: Figure 1 The L-shape shown, i.e., the top of profile 02 does not have an A side (the A side is generally used to describe the structural side located at the top of the profile and perpendicular to the height direction of the profile), then step S4 can be implemented before step S5, or step S5 can be implemented before step S4, or, step S4 and step S5 can be implemented simultaneously.
[0145] If step S4 is implemented before step S5, the frame 2 can be first fixed to form a quadrilateral frame, and then the laminate 1 and the frame 2 are aligned in direction X and direction Z, and then the laminate 1 is located above the frame 2 and the laminate 1 and the frame 2 are kept at a distance in direction Y, and then the laminate 1 and the frame 2 are bonded. In the process of bonding the laminate 1 and the frame 2, the frame 2 that has been fixed to form a quadrilateral frame in step S4 is not easy to shift relative to the laminate 1 along direction X and direction Z, so that the uncured adhesive 3 is not easy to flow freely in direction X and direction Z relative to the laminate 1 and the frame 2, which is conducive to improving the reliability of the bonding between the laminate 1 and the frame 2. Secondly, the quadrilateral frame 2 that has been fixed in step S4 has fewer degrees of freedom to be positioned by the clamp in step S5, that is, the positioning difficulty is lower.
[0146] If step S5 is performed before step S4, the laminate 1 and the frame 2 may be bonded first, and then the two free portions of the frame 2 may be fixedly connected by bonding. Of course, the two free portions of the frame 2 may also be fixedly connected by welding.
[0147] If step S4 and step S5 are performed simultaneously, the frame 2 and the laminate 1 and the two free parts of the frame 2 can be bonded at the same time. Alternatively, the frame 2 and the laminate 1 and the two free parts of the frame 2 can be bonded at the same time.
[0148] If the top of the profile 02 has an A edge, that is, the cross-sectional shape of the profile 02 is a U-shaped shape, no matter how long the A edge is, the A edge interferes with the movement of the laminate 1 in the direction Y, and only step S5 can be implemented first, and then step S4.
[0149] Optionally, see Figure 6 As shown, the bottom surface 12 of the laminate 1 includes a bonded portion 122. The bottom structural edge 22 of the frame 2 is used to support the bonded portion 12. Step S5 includes:
[0150] Step S51: Figure 6 As shown, the laminate 1 and the frame 2 are positioned respectively to form a spacing space 4 between the bottom structure edge 22 and the bonded portion 122 in the direction Y, and an adhesive 3 is placed in the spacing space 4 to bond the bottom structure edge 22 and the bonded portion 122.
[0151] The height of the bottom surface 12 of the laminate 1 is higher than the height of the bottom structural edge 22, but the height of the bottom surface 12 of the laminate 1 is lower than the height of the top of the side structural edge 21. Before the adhesive 3 is cured, the frame 2 and the laminate 1 can be brought close to each other in the direction Y so that the bubbles in the adhesive 3 are squeezed out, so that the bottom structural edge 22 and the bonded portion 122 are fully in contact with the adhesive 3, thereby making the reliability of the bonding between the laminate 1 and the frame 2 higher.
[0152] Optionally, step S51 includes step S511: please refer to Figure 6-Figure 9 As shown, the adhesive 3 is placed layer by layer in the space 4 in the direction from the inside of the space 4 to the outside of the space 4, or in other words, the adhesive 3 is placed layer by layer in the space 4 in the direction perpendicular to the direction Y. This step S511 has the following advantages: the first layer of adhesive 3 placed first is not easy to flow to the outside of the space 4 in a short time. Since the force of the adhesive spraying machine can be used to spray the adhesive 3 outward, even if the first layer of adhesive 3 placed first has a tendency to flow to the outside of the space, the second layer of adhesive 3 placed later can exert a force on the first layer of adhesive to inhibit the first layer of adhesive from flowing to the outside of the space, so that the first layer of adhesive can better fill the innermost space of the space. Furthermore, the adhesive 3 placed layer by layer can discharge the air inside the space 4 layer by layer, and the adhesive 3 placed first is not easy to flow to the outside of the space due to the negative air pressure. In the process of placing the last layer of adhesive 3, since the previously placed layers of adhesive 3 have begun to gradually solidify but have not completely solidified, the previously placed layers of adhesive 3 themselves are not easy to flow to the outside of the spacing space 4. The previously placed layers of adhesive 3 can limit the flow of the last layer of adhesive 3 to the outside of the spacing space 4 through the bonding force, and make the surface of the last layer of adhesive 3 relatively neat after solidification. In summary, step S511 can, on the one hand, make the adhesive 3 fill the spacing space 4 better, so that it is not easy to have bubbles in the spacing space 4, thereby improving the reliability of the bonding between the laminate 1 and the frame 2; on the other hand, step S511 makes it difficult for the adhesive 3 to overflow to the outside of the spacing space 4, and the possibility of subsequent glue filling is relatively small, thereby achieving the technical effect of saving the amount of adhesive 3.
[0153] The number of layers of adhesive glue 3 placed in step S511 may be at least two layers, and the specific number of layers is related to the amount of glue sprayed.
[0154] In addition, the process of placing each layer of adhesive 3 is to use the glue sprayer to move from a set position in the spacing space 4 to another set position along a set direction and path, and the glue sprayer sprays glue while moving. For example, after placing the first layer of adhesive 3 in the spacing space 4, the glue sprayer can move and spray glue to form a second layer of adhesive 3.
[0155] Optionally, step S511 includes:
[0156] Step S511a: First, place a single layer of adhesive 3 in the spacing space 4 between the first sub-frame 2a and the laminate 1, then place a single layer of adhesive 3 in the spacing space 4 between the second sub-frame 2b and the laminate 1, then place a single layer of adhesive 3 in the spacing space 4 between the third sub-frame 2c and the laminate 1, and finally place a single layer of adhesive 3 in the spacing space 4 between the fourth sub-frame 2d and the laminate 1.
[0157] Step S511b: Execute step S511a at least twice.
[0158] Under the settings of step S511a and step S511b, a glue sprayer can be used to complete the work of placing the adhesive 3 layer by layer, with fewer restrictions on the volume size of the glue sprayer and lower control difficulty.
[0159] Among them, the order of placing the single layer of adhesive 3 can also be opposite to the order in step S511a, that is, the single layer of adhesive 3 can be placed in the spacing space 4 between the fourth sub-frame 2d and the laminate 1 first, and then the single layer of adhesive 3 can be placed in the spacing space 4 between the third sub-frame 2c and the laminate 1, and then the single layer of adhesive 3 can be placed in the spacing space 4 between the second sub-frame 2b and the laminate 1, and then the single layer of adhesive 3 can be placed in the spacing space 4 between the first sub-frame 2a and the laminate 1.
[0160] In addition, a glue sprayer may be used to form continuous adhesive glue 3 on the first sub-frame 2a, the second sub-frame 2b, the third sub-frame 2c and the fourth sub-frame 2d. Alternatively, a glue sprayer can be used to form separate adhesives 3 between the first sub-frame 2a, the second sub-frame 2b, the third sub-frame 2c and the fourth sub-frame 2d, that is, there is a separation space between the adhesive 3 located at the first sub-frame 2a and the adhesive 3 located at the second sub-frame 2b, there is a separation space between the adhesive 3 located at the second sub-frame 2b and the adhesive 3 located at the third sub-frame 2c, there is a separation space between the adhesive 3 located at the third sub-frame 2c and the adhesive 3 located at the fourth sub-frame 2d, and there is a separation space between the adhesive 3 located at the fourth sub-frame 2d and the adhesive 3 located at the first sub-frame 2a. The above-mentioned separation space 4 serves as a deformation space for the adhesive 3 during and after curing, and is used to release the stress generated by the deformation of the adhesive 3, thereby reducing the possibility of large stress locally existing on the contact surface between the laminate 1 and the adhesive 3, thereby reducing the possibility of structural problems such as plastic deformation, cracking or damage of the laminate 1.
[0161] Furthermore, each layer of adhesive 3 in the spacing space 4 between the first sub-frame 2a and the laminate 1 is extended along the extension direction (direction Z) of the first sub-frame 2a. Similarly, each layer of adhesive 3 in other sub-frames is extended along the extension direction of the corresponding sub-frame.
[0162] Optionally, if the frame 2 is a quadrilateral frame, the frame 2 includes a first sub-frame 2a, a second sub-frame 2b, a third sub-frame 2c and a fourth sub-frame 2d, and accordingly, step S511 includes:
[0163] Step S511c: placing adhesive 3 layer by layer in the spacing space 4 between the first sub-frame 2a and the laminate 1.
[0164] Step S511d: placing adhesive 3 layer by layer in the spacing space 4 between the second sub-frame 2b and the laminate 1.
[0165] Step S511e: placing adhesive 3 layer by layer in the spacing space 4 between the third sub-frame 2c and the laminate 1.
[0166] Step S511f: placing adhesive 3 layer by layer in the spacing space 4 between the fourth sub-frame 2d and the laminate 1.
[0167] Regarding the execution order of step S511c, step S511d, step S511e and step S511f, step S511c, step S511d, step S511e and step S511f can be executed in turn. For example, adhesive glue 3 can be placed layer by layer in the interval 4 between the first sub-frame 2a and the laminate 1 and filled with adhesive glue 3, then adhesive glue 3 can be placed layer by layer in the interval 4 between the second sub-frame 2b and the laminate 1 and filled with adhesive glue 3, then adhesive glue 3 can be placed layer by layer in the interval 4 between the third sub-frame 2c and the laminate 1 and filled with adhesive glue 3, and then adhesive glue 3 can be placed layer by layer in the interval 4 between the fourth sub-frame 2d and the laminate 1 and filled with adhesive glue 3. Under this setting, the work of placing adhesive glue 3 layer by layer can be completed by a glue spraying machine, and the volume size restriction requirements of the glue spraying machine are relatively small, and the control difficulty is relatively low.
[0168] In other embodiments, step S511f, step S511e, step S511d and step S511c may also be performed in turn.
[0169] Regarding the execution order of step S511c, step S511d, step S511e and step S511f, step S511c, step S511d, step S511e and step S511f can also be executed synchronously, for example, four glue spraying machines are used to spray glue at the corresponding positions at the same time. Under this setting, the molding efficiency of the adhesive 3 is high, so that the production efficiency of the photovoltaic module 10 is also high.
[0170] If border 2 is a border without side A, please refer to Fig.10As shown, the side structure edge 21 of the frame 2 may be provided with a first through hole 211. Accordingly, step S5 includes:
[0171] Step S52: Please refer to Fig.10 As shown, the laminate 1 and the frame 2 are positioned respectively so that a spacing space 4 is formed between the bottom structure edge 22 and the bonded portion 122 in the direction Y, and the first through hole 211 is connected to the spacing space 4.
[0172] Step S53: Please refer to Fig.11 As shown, the blocking member 5 is used to block the opening of the spacing space 4 away from the first through hole 211 .
[0173] Step S54: Please refer to Fig.12 As shown, the adhesive 3 is injected into the spacing space 4 through the first through hole 211 .
[0174] Step S55: Please refer to Fig.13 As shown, the laminate 1 and the frame 2 are brought closer to each other in the direction Y, so that part of the adhesive 3 overflows from the spacing space 4 to the first through hole 211 .
[0175] Regarding step S52, step S53, step S54 and step S55, this setting can prevent the adhesive 3 from easily overflowing to the outside of the spacing space 4, and the possibility of subsequent glue filling is relatively small, thereby achieving the technical effect of saving the amount of adhesive 3; secondly, the sealing member 5 can play a good shaping role on the uncured adhesive 3, so that the surface of the adhesive 3 is relatively neat after curing; furthermore, the glue sprayer only needs to inject glue into the first through hole 211, and the glue sprayer does not need to move a large range relative to the laminate 1 and the frame 2. The working energy consumption of the glue sprayer is low, and the nozzle of the glue sprayer can be located on the side of the frame 2 away from the laminate 1. The movable range of the nozzle of the glue sprayer is large, and the difficulty of controlling the movement of the nozzle of the glue sprayer is relatively low, and the nozzle of the glue sprayer is not easy to interfere with the movement of the laminate 1, thereby reducing the possibility of collision between the laminate 1 and the nozzle of the glue sprayer.
[0176] The blocking member 5 may be a plate-shaped member, a strip-shaped member or other structural member that can block the separation space 4 .
[0177] In addition, the plugging member 5 can be removed after the adhesive 3 is cured. The surface material of the plugging member 5 is required to be a material that is not easy to bond, for example, the surface of the plugging member 5 has an anti-stick coating, so that the plugging member 5 can be separated from the cured adhesive 3 without damaging the cured adhesive 3.
[0178] In other embodiments, whether the frame 2 has an A side or not, Figure 14-15As shown, the bottom structural edge 22 of the frame 2 may be provided with a second through hole 223. Accordingly, step S54 may be changed to: injecting adhesive 3 into the spacing space 4 through the second through hole 223. The technical effect of this embodiment is the same as that of the embodiment of injecting adhesive into the first through hole 211, and will not be repeated here.
[0179] The present application also provides a photovoltaic module manufactured using the manufacturing method described above. Figure 5 As shown, the photovoltaic module 10 includes a laminate 1 and a frame 2. Fig.16 As shown, the laminate 1 includes a top surface 11, a bottom surface 12 and a side surface 13, the top surface 11 includes a first light incident portion 111 (a portion directly irradiated by sunlight) and a pressed portion 112, and the bottom surface 12 includes a second light incident portion 121 (a portion irradiated by reflected sunlight) and a bonded portion 122. The pressed portion 112 is close to the edge of the top surface 11, and the first light incident portion 111 is located on the side of the pressed portion 112 that is away from the edge of the top surface 11. The bonded portion 122 is close to the edge of the bottom surface 12, and the second light incident portion 121 is located on the side of the edge of the bonded portion 122 that is away from the bottom surface 12. The projection of the pressed portion 112 on the plumb direction (opposite to the direction Y) of the laminate 1 is located within the bonded portion 122. Please refer to Figure 4 As shown, taking the first sub-frame 2a as an example, the frame 2 includes a connected side structure edge 21 and a bottom structure edge 22. The side structure edge 21 can abut against the side surface 13, and the bottom structure edge 22 can support and bond to the bonded portion 122.
[0180] Among them, since the frame 2 is made of the same profile 02, among the first sub-frame 2a, the second sub-frame 2b, the third sub-frame 2c and the fourth sub-frame 2d included in the frame 2, the first sub-frame 2a and the second sub-frame 2b are integrally formed, the second sub-frame 2b and the third sub-frame 2c are integrally formed, and the third sub-frame 2c and the fourth sub-frame 2d are integrally formed. Under this setting, the structural strength of the frame 2 is relatively high, and the frame 2 can better protect, support and fix the laminate 1.
[0181] In addition, the cross-sectional shape of the frame 2 can be as follows: Figure 4The L-shaped frame 2 shown in the figure is simpler in structure than the frame in the prior art, and the frame 2 is easy to manufacture. Accordingly, the manufacturing difficulty of the photovoltaic module 10 is relatively low; the frame 2 is small in size, so that the photovoltaic module 10 occupies less space, which is convenient for storing or loading a large number of photovoltaic modules 10; the frame 2 is light in weight, and the photovoltaic module 10 is easy to carry and assemble. Moreover, the requirements for the load limit of the components used to carry the photovoltaic module 10 are relatively low, and the photovoltaic module 10 can be installed in more environments; the L-shaped frame 2 is located on the top surface 11 of the laminate 1 Foreign matter (such as dust and snow) does not have a significant obstructive effect in the direction perpendicular to direction Y (direction X and direction Z), and the foreign matter can easily detach from the top surface 11 of the laminate 1 under the action of external force, especially when the top surface 11 of the laminate 1 is inclined relative to the horizontal plane, or when it is blown by the wind, the top surface 11 of the laminate 1 is less likely to accumulate foreign matter, and the first light incident portion 111 of the top surface 11 is not easily blocked by foreign matter. The area of the first light incident portion 111 illuminated by sunlight is larger, so that the power generation efficiency of the photovoltaic module 10 is higher.
[0182] Furthermore, the cross-sectional shape of the frame 2 may also be as follows: Fig.15 In the shape shown, although the frame 2 has a top structural edge 23 (also called A edge), since the dimension of the A edge in the direction X is shorter, Fig.15 The frame 2 shown is also relatively small in size and relatively light in weight.
[0183] In addition, the pressing portion 112 is used to Fig.17 The mounting assembly 20 shown is directly pressed, and the bottom structural edge 22 is used to be Fig.17 The mounting assembly 20 is shown as being directly supported.
[0184] Regarding the structure of the laminate 1, the laminate 1 includes a stacked first photovoltaic glass, a first adhesive film, a cell string (including a cell sheet), a second adhesive film, and a second photovoltaic glass.
[0185] Please refer to Fig.16 As shown, the pressed portion 112 is adjacent to the edge of the top surface 11 , and the frame 2 adapted by the laminate 1 is the frame shown in FIG. 14 .
[0186] Optionally, see Fig.18 As shown, the top surface 11 further includes a limited portion 113, the limited portion 113 is adjacent to the edge of the top surface 11, the limited portion 113 is located between the pressed portion 112 and the edge of the top surface 11, and the pressed portion 112 is located between the limited portion 113 and the first light incident portion 111. Fig.19 As shown, the frame 2 includes a top structural edge 23. The top structural edge 23 extends from the top of the side structural edge 21 to the Fig.18The limited portion 113 is shown, and the top structure edge 23 is in limited contact with the limited portion 113 to limit the laminate 1 from separating from the frame 2 along the direction Y.
[0187] Please refer to Fig.19 As shown, the top structure edge 23 has a slope 231 away from the laminate 1, and the slope 231 includes a first edge 231a and a second edge 231b. The projection of the first edge 231a in the plumb direction of the frame 2 (opposite to the direction Y) is located at the side structure edge 21. The height of the first edge 231a is higher than the height of the second edge 231b. The projection of the second edge 231b in the plumb direction of the frame 2 (opposite to the direction Y) is located at the limited portion 113. This arrangement makes it less likely that the inclined surface 231 of the top structural edge 23 will hinder foreign matter (such as dust and snow) located on the top surface 11 of the laminate 1 in the direction X, and the foreign matter can be easily separated from the top surface 11 of the laminate 1 under the action of external force. In particular, when the top surface 11 of the laminate 1 is tilted relative to the horizontal plane, or when it is blown by the wind, the top surface 11 of the laminate 1 is not easy to accumulate foreign matter, and the first light incident portion 111 of the top surface 11 is not easily blocked by foreign matter, thereby making the power generation efficiency of the photovoltaic module 10 higher.
[0188] Optionally, see Figure 20-21 As shown, the bottom structure edge 22 of the first sub-frame 2a has a first connecting edge 224, and the bottom structure edge 22 of the second sub-frame 2b has a second connecting edge 225, and the first connecting edge 224 and the second connecting edge 225 are connected.
[0189] Optionally, see Fig. 20 As shown, the first connecting edge 224 includes a first arc portion 224a, the second connecting edge 225 includes a second arc portion 225a, and the first arc portion 224a and the second arc portion 225a are connected. Under this setting, compared with the linear contact structure in the prior art, the length dimension of the arc contact structure between the first connecting edge 224 and the second connecting edge 225 is larger, that is, there are more connecting positions between the first connecting edge 224 and the second connecting edge 225, and accordingly, the connection strength between the first connecting edge 224 and the second connecting edge 225 is larger, and the structural strength of the frame 2 is larger.
[0190] Of course, the third sub-frame 2c and the fourth sub-frame 2d may also have corresponding arc portions, so that the second sub-frame 2b is connected to the third sub-frame 2c through an arc contact structure, so that the third sub-frame 2c is connected to the fourth sub-frame 2d through an arc contact structure, and so that the fourth sub-frame 2d is connected to the first sub-frame 2a through an arc contact structure. Under this arrangement, the structural strength of the frame 2 is relatively large.
[0191] Optionally, see Fig.21As shown, the first connecting edge 224 includes a first fold line portion 224b, the second connecting edge 225 includes a second fold line portion 225b, and the first fold line portion 224b and the second fold line portion 225b are connected. Under this setting, compared with the linear contact structure in the prior art, the length dimension of the fold line contact structure between the first connecting edge 224 and the second connecting edge 225 is larger, that is, there are more connecting positions between the first connecting edge 224 and the second connecting edge 225, and accordingly, the connection strength between the first connecting edge 224 and the second connecting edge 225 is larger, and the structural strength of the frame 2 is larger.
[0192] Of course, the third sub-frame 2c and the fourth sub-frame 2d may also have corresponding fold line portions, so that the second sub-frame 2b is connected to the third sub-frame 2c through a fold line contact structure, so that the third sub-frame 2c is connected to the fourth sub-frame 2d through a fold line contact structure, and so that the fourth sub-frame 2d is connected to the first sub-frame 2a through a fold line contact structure. Under this arrangement, the structural strength of the frame 2 is relatively large.
[0193] In other embodiments, any pair of two connected sub-frames in the frame 2 can be connected by an arc contact structure and a fold line contact structure.
[0194] Optionally, see Fig. 22 and Fig.23 As shown, the bottom structural edge 22 includes a first section 221 and a second section 222, the first section 221 is connected to the side structural edge 21, the end of the first section 221 away from the side structural edge 21 is connected to the second section 222, and the second section 222 is bent in the opposite direction of the first section 221 along the direction Y. It can also be said that the second section 222 is bent toward the side away from the laminate 1 relative to the first section 221. Under this setting, more adhesive 3 can be placed between the second section 222 and the laminate 1, and more adhesive 3 can play a good buffering role, and the adhesive 3 can be deformed along the inclined surface of the second section 222 in the direction X, and stress can be released through deformation. The above effect can reduce the contact stress between the second section 222 and the laminate 1, thereby reducing the possibility of the laminate 1 being squeezed and damaged by the second section 222.
[0195] Optionally, see Fig. 22 and Fig.23As shown, the first section 221 has a supported surface 2212 and a supporting surface 2211 for supporting the bonded portion 122 of the bottom surface 12 of the laminate 1, the supporting surface 2211 has a third edge 2211a connected to the side structure edge 21 and a fourth edge 2211b away from the side structure edge 21, and the height of the fourth edge 2211b is lower than the height of the third edge 2211a, so that there is an acute angle α between the supporting surface 2211 and the supported surface 2212, and the acute angle α satisfies 0.1° to 5°. Specifically, the acute angle α can be 0.1°, 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5° or 5°. Under this setting, the adhesive 3 can be deformed in direction X along the inclined supporting surface 2211, and the stress can be released through deformation. The above effect can reduce the contact stress between the supporting surface 2211 and the laminate 1, thereby reducing the possibility of the supporting surface 2211 squeezing and damaging the laminate 1.
[0196] Among them, the supported surface 2212 is used to be Fig.17 The mounting assembly 20 is shown supporting.
[0197] The present application embodiment further provides a photovoltaic component, please refer to Fig.17 As shown, the photovoltaic component includes the photovoltaic assembly 10 and the mounting assembly 20 described above. Accordingly, the photovoltaic component also has the technical effects of the photovoltaic assembly 10 described above, which will not be repeated here.
[0198] Wherein, the installation assembly 20 includes an upper short frame assembly 201, a lower short frame assembly 202 and a pressing block 203. The upper short frame assembly 201 and the lower short frame assembly 202 are detachably connected, and the pressing block 203 is used to connect with a fixed object (such as a bracket, a purlin or a wall), and the upper short frame assembly 201 is pressed and fixed by the pressing block 203. The upper short frame assembly 201 includes a detachably connected upper short frame body 2011 and an upper shock absorbing member 2012, and the lower short frame assembly 202 includes a detachably connected lower short frame body 2021 and a lower shock absorbing member 2022. The upper short frame body 2011 and the lower short frame body 2021 are snap-connected, and the upper short frame body 2011 is pressed by the pressing block 203, the upper shock absorbing member 2012 presses the pressed portion 112 of the top surface 11 of the laminate 1, and the lower shock absorbing member 2022 supports the supported surface 2212 of the bottom structural edge 22 of the frame 2. The upper shock absorbing member 2012 and the lower shock absorbing member 2022 are both made of flexible materials and play a role in shock absorption. The lower short frame body 2021 has a mounting groove 2021a, and the mounting groove 2021a is used to place a fastener so that the mounting groove 2021a can be detachably connected to a fixed object (such as a bracket, purlin or wall) through the fastener.
[0199] Please refer to Fig.24As shown, in a top-down perspective, the length dimension of the mounting assembly 20 is smaller than the length dimension of the photovoltaic assembly 10. Under this setting, the mounting assembly 20 has less obstructive effect on foreign matter (such as dust and snow) located on the top surface 11 of the photovoltaic assembly 10 in directions X and Y. Under the action of external force, foreign matter can be easily detached from the top surface 11 of the photovoltaic assembly 10, and the area of the top surface 11 of the photovoltaic assembly 10 that can be illuminated by sunlight is larger, thereby making the photovoltaic assembly 10 have a higher power generation efficiency.
[0200] In addition, the position of any mounting assembly 20 relative to the photovoltaic assembly 10 in the direction X or the direction Y can be adjusted, thereby improving the force condition between the photovoltaic assembly 10 and the mounting assembly 20 .
[0201] Furthermore, the number of the required mounting components 20 may be at least four, and at least two mounting components 20 may be installed on the same side of the photovoltaic component 10 .
[0202] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
