[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0024] like Figure 1 The schematic diagram of the photovoltaic component is shown, and the photovoltaic component includes a color steel tile 4, an adhesive bracket 3 and a photovoltaic module 2. The adhesive bracket 3 is mounted on the color steel tile 4, and the photovoltaic module 2 is mounted on the adhesive bracket 3. In this embodiment, the photovoltaic module 2 is mounted on the color steel tile 4 through the adhesive bracket 3. Among them, the photovoltaic module 2 can generate current under certain illumination conditions, and the photovoltaic module 2 is installed on the outer surface of the building's enclosure structure to provide electricity.

[0025] When installing the photovoltaic module 2, it is necessary to locate the positions of the photovoltaic module 2 and the bonding bracket 3 to ensure the accuracy of the bonding position of the photovoltaic module 2. However, the frame of the photovoltaic module 2 is relatively thin, and milling or marking the frame as a bonding mark will damage the frame of the photovoltaic module 2, and the process is complicated and costly.

[0026] To this end, this embodiment provides a positioning tool 1 to solve the above technical problems.

[0027] like Figure 2The figure shows the coordination diagram of the positioning fixture 1 and the photovoltaic module 2, and the photovoltaic module 2 includes two long sides 22 arranged opposite to each other and two short sides 21 arranged opposite to each other. When installing the photovoltaic module 2, first install two positioning fixtures 1 respectively on the two short sides 21 of the photovoltaic module 2 and close to one long side 22, and then install the positioning fixture 1 and the photovoltaic module 2 together to the bonding bracket 3. The positioning fixture 1 can position the photovoltaic module 2 on the bonding bracket 3, reduce the risk of the photovoltaic module 2 being skewed after installation, so as to ensure the accuracy of the installation position of each photovoltaic module 2 and improve the appearance effect.

[0028] It should be noted that the lengths of the four sides of the photovoltaic module 2 can also be equal, and the positioning tool 1 can be installed on which pair of sides of the photovoltaic module 2 according to the operator's installation of the photovoltaic module 2, so that the two positioning tools 1 can define the position of the photovoltaic module 2 according to the same bonding bracket 3. The specific definition can be based on actual conditions, and this embodiment does not limit it here.

[0029] The structure of the positioning tool 1 and how the positioning tool 1 locates the installation position of the photovoltaic module 2 will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 3 The figure shows a schematic diagram of the structure of the positioning tool 1, which includes a clamping portion 11, a limiting portion 12, an abutting portion 13 and a hollow area 14. The clamping portion 11 is connected to the limiting portion 12, the limiting portion 12 is located at the periphery of the clamping portion 11, and the limiting portion 12 extends along the length direction Y of the positioning tool 1. The abutting portion 13 is connected to the limiting portion 12, and along the height direction Z of the positioning tool 1, the abutting portion 13 extends in a direction away from the clamping portion 11. The positioning tool 1 is also provided with a hollow area 14, and along the height direction Z of the positioning tool 1, the hollow area 14 extends from the limiting portion 12 to the abutting portion 13.

[0031] Among them, the clamping portion 11 is used to clamp and cooperate with the short side of the photovoltaic component, the limiting portion 12 is used to limit the position of the photovoltaic component relative to the adhesive bracket, the abutment portion 13 is used to limit the spacing between the short sides of adjacent photovoltaic components, and the hollow position 14 is used to facilitate the operator to remove the positioning tool 1 from the photovoltaic component.

[0032] Specifically, Figure 4 The schematic diagram of the photovoltaic module 2 installed on the color steel tile 4 is shown. Figure 5 Shown Figure 4 Please refer to the enlarged diagram of part A in the middle Figure 3 and Figure 5 The clamping portion 11 can be a groove structure. By inserting the clamping portion 11 into the short side 21 of the photovoltaic component 2, the clamping portion 11 is clamped and matched with the short side 21 of the photovoltaic component 2, so as to achieve the installation of the positioning tool 1 on the short side 21 of the photovoltaic component 2.

[0033] Among them, the clamping part 11 can have a certain elasticity, so that after the clamping part 11 is matched with the short side 21 of the photovoltaic component 2, the clamping part 11 can be wrapped around the short side 21 of the photovoltaic component 2, so that the clamping part 11 and the photovoltaic component 2 maintain a close fit, reducing the risk of the positioning tooling 1 being separated from the photovoltaic component 2.

[0034] Please continue to refer to Figure 3 The clamping portion 11 may be a groove structure, and the groove of the clamping portion 11 expands outward. That is, at least one side of the clamping portion 11 is provided with a guide section 111, and the guide section 111 is inclined toward the outside, so that the groove of the clamping portion 11 expands outward, so that the clamping portion 11 can be matched with the short side 21 of the photovoltaic module 2.

[0035] The guide section 111 may be provided on one side of the clamping portion 11, or the guide section 111 may be provided on both sides of the clamping portion 11. The specific setting may be made according to actual conditions, and this embodiment does not limit this.

[0036] The side surface of the conductive segment may be an inclined surface, or the side surface of the conductive segment may be an arc surface, which may be set according to actual conditions and is not limited in this embodiment.

[0037] Alternatively, in some embodiments, the clamping portion 11 may also be configured as other structures that can be detachably mounted on the short side 21 of the photovoltaic component 2 , which may be specifically configured according to actual conditions and is not limited in this embodiment.

[0038] Please continue to refer to Figure 4 and Figure 5 , along the length direction Y of the positioning tool 1, the limiting part 12 has a first end 121 and a second end 122, the first end 121 abuts against the long side 22 of the photovoltaic module 2, and the second end 122 abuts against the side wall 31 of the bonding bracket 3. That is to say, when the positioning tool 1 is installed on the photovoltaic module 2, the first end 121 is first abutted against the long side 22 of the photovoltaic module 2. When the positioning tool 1 and the photovoltaic module 2 are installed on the bonding bracket 3 together, the second end 122 is tangent to the side wall 31 of the bonding bracket 3. At this time, the position between the first end 121 and the photovoltaic module 2 remains unchanged, so that the distance between the long side 22 of the photovoltaic module 2 and the side wall 31 of the bonding bracket 3 is limited by the first end 121 and the second end 122 of the limiting part 12, so that the parallel distance between the long side 22 of each photovoltaic module 2 and the corresponding bonding bracket 3 is kept fixed, so that a row of photovoltaic modules 2 are arranged in parallel, ensuring that the photovoltaic modules 2 are installed neatly.

[0039] Figure 6The figure shows a top view of the positioning tool 1. Along the length direction Y of the positioning tool 1, the two ends of the positioning tool 1 are the first end 121 and the second end 122 respectively. Along the length direction Y of the positioning tool 1, the distance between the first end 121 and the second end 122 is H1, and H1 is the parallel distance from the long side 22 of the photovoltaic component 2 to the bonding bracket 3. In this embodiment, H1 can be adjusted according to demand. For example, if the parallel distance between the long side 22 of the photovoltaic component 2 and the side wall 31 of an adjacent bonding bracket 3 is set to 200mm-300mm, then H1 is set to 200mm-300mm. For example, if the parallel distance between the long side 22 of the photovoltaic component 2 and the side wall 31 of an adjacent bonding bracket 3 is 245mm, then H1 needs to be set to 245mm. H1 can be adjusted according to the actual size of the photovoltaic component during installation, and can be further enlarged or reduced. H1 can be specifically set according to actual conditions to ensure that the distance H1 between the first end 121 and the second end 122 on the positioning tool 1 is equal to the parallel distance from the long side 22 of the photovoltaic component 2 to the bonding bracket 3. This embodiment is not limited here.

[0040] Among them, along the length direction Y of the positioning tool 1, the length of the clamping part 11 can be smaller than the length of the limiting part 12, so that the clamping part 11 is away from the second end 122 of the limiting part 12, so as to reduce the risk of contact between the clamping part 11 and the adhesive on the adhesive bracket 3, so that the positioning tool 1 can be reused to save costs.

[0041] Alternatively, along the length direction Y of the positioning fixture 1, the length of the clamping portion 11 may also be equal to the length of the limiting portion 12. The length may be set according to actual conditions, and this embodiment does not limit this.

[0042] like Figure 7 The schematic diagram of the positioning tool 1 is shown, and the second end portion 122 has a bevel 122a, and the bevel 122a is inclined toward the side away from the clamping portion 11. That is, by providing the bevel 122a at the second end portion 122, the contact area between the second end portion 122 and the side wall 31 of the bonding bracket 3 is reduced, thereby reducing the risk of the second end portion 122 contacting the adhesive on the bonding bracket 3, so that the positioning tool 1 can be reused, and the positioning accuracy of the positioning tool 1 when it is reused is guaranteed.

[0043] At the same time, by setting the hypotenuse 122a to be inclined toward the side away from the clamping portion 11, when the second end 122 is tangent to the side wall 31 of the bonding bracket 3, the clamping portion 11 is at a certain distance from the bonding bracket 3, reducing the risk of contact between the clamping portion 11 and the adhesive on the bonding bracket 3.

[0044] Please continue to refer to Figure 6 and Figure 7The hollow area 14 is arranged at the middle position between the limiting portion 12 and the abutting portion 13. In this embodiment, by providing the hollow area 14, it is convenient for the operator to place his hand in the hollow area 14 to take the positioning tool 1, and remove the positioning tool 1 on the photovoltaic module 2 after the installation is completed, so as to prepare for the installation of the next photovoltaic module 2, thereby saving costs.

[0045] like Figure 8 Shown Figure 1 Please refer to the enlarged diagram of part B in the middle Figure 7 and Figure 8 The abutment portion 13 is located on one side of the clamping portion 11 along the width direction X of the positioning fixture 1, and the abutment portion 13 is connected to the side of the limiting portion 12 away from the clamping portion 11, and there is a preset distance between the clamping portion 11 and the abutment portion 13. When installing the photovoltaic module 2, the abutment portion 13 can fit with the short side 21 of the adjacent photovoltaic module 2, so that there is a certain distance between the adjacent photovoltaic modules 2, so that the components under the photovoltaic module 2 can be viewed from the distance between the adjacent photovoltaic modules 2. In addition, the short side 21 of the photovoltaic module 2 will also be provided with other fixed components. By leaving a distance between two adjacent photovoltaic modules 2, the fixed components can be avoided to prevent interference problems.

[0046] like Fig. 9 The figure shows a side view of the positioning fixture 1. Along the width direction X of the positioning fixture 1, the distance between the clamping portion 11 and the abutting portion 13 is H2, and H2 is the distance between the short sides 21 of adjacent photovoltaic components 2. In this embodiment, H2 can be adjusted according to demand. For example, when the spacing between the short sides 21 of adjacent photovoltaic components 2 is set to 15mm-30mm, H2 is set to 15mm-30mm. For example, when the distance between the short sides 21 of adjacent photovoltaic components 2 is 20mm, H2 needs to be set to 20mm. H2 can be adjusted according to the actual size of the photovoltaic component during installation, and further enlarged or reduced. H2 can be specifically set according to the actual situation to ensure that the distance H2 between the clamping portion 11 and the abutting portion 13 is equal to the distance between the short sides 21 of adjacent photovoltaic components 2. This embodiment is not limited here.

[0047] Please continue to refer to Fig. 9, along the height direction Z of the positioning fixture 1, the abutting portion 13 extends in the direction away from the limiting portion 12, so that the length of the abutting portion 13 along the height direction Z of the positioning fixture 1 is longer than the width of the clamping portion 11 along the height direction Z of the positioning fixture 1, so that when installing the photovoltaic module 2, the abutting portion 13 first contacts the side wall 31 of the adhesive bracket 3, and then the photovoltaic module 2 contacts the bracket. That is, when the abutting portion 13 contacts the side wall 31 of the adhesive bracket 3 first, the installation position of the photovoltaic module 2 has been positioned, avoiding the middle part of the photovoltaic module 2 bending downward due to the softness of the photovoltaic module 2, and contacting the adhesive on the adhesive bracket 3 before the two sides, resulting in installation deviation of the photovoltaic module 2 and affecting the installation effect.

[0048] Please continue to refer to Fig. 9 , along the height direction Z of the positioning tool 1, the distance between the clamping part 11 and the lower end of the abutting part 13 is H3, and H3 is the distance at which the positioning tool 1 contacts the bonding bracket 3 before the photovoltaic component 2. In this embodiment, H3 can be adjusted according to demand. For example, when installing the photovoltaic component 2, the middle part of the photovoltaic component 2 is bent downward, so that the middle part of the photovoltaic component 2 is 38mm lower than the short side 21 of the photovoltaic component 2, then H3 can be set to be greater than 38mm, such as H3 can be set to 39mm-45mm, so that the positioning tool 1 contacts the bonding bracket 3 before the middle part of the photovoltaic component 2 to achieve positioning. H3 can be adjusted according to the size of the photovoltaic component when it is actually installed, and further enlarged or reduced. H3 can be specifically set according to the actual situation to ensure that the distance H3 between the clamping part 11 and the lower end of the abutting part 13 is greater than the height of the middle part of the photovoltaic component 2 compared to the short side 21 of the photovoltaic component 2. This embodiment is not limited here.

[0049] Further, please refer to Figure 3 , along the height direction Z of the positioning fixture 1, a bending section 131 is provided at one end of the abutting portion 13 away from the clamping portion 11, and the bending section 131 is bent toward the inner side of the positioning fixture 1. In this embodiment, by providing the bending section 131 at the abutting portion 13, when the photovoltaic module 2 is installed, the bending section 131 can guide the contact between the abutting portion 13 and the adjacent photovoltaic module 2, so that after the photovoltaic module 2 is installed in place, the abutting portion 13 can be in close contact with the short side 21 of the adjacent photovoltaic module 2, so as to maintain the same spacing between the short sides 21 of the adjacent photovoltaic modules 2.

[0050] Please continue to refer to Fig. 9 In some embodiments, the positioning tool 1 can be a split structure, wherein the first end 121 of the limiting portion 12 is a split plate-like structure, and the other structures of the positioning tool 1 except the first end 121 are an integrated structure, and the two are fixed by a connecting piece (not shown in the figure).

[0051] For details, please continue to refer to Fig. 9The positioning tool 1 also includes a connecting piece (not shown in the figure) and a connecting portion 15. The connecting portion 15 is connected to the clamping portion 11, and the connecting portion 15 is arranged between the clamping portion 11 and the abutting portion 13. The connecting portion 15 is provided with a first connecting hole 151. A second connecting hole 121a is arranged at a position corresponding to the first connecting hole 151 at the first end 121. The first connecting hole 151 is coaxially arranged with the second connecting hole 121a along the length direction Y of the positioning tool 1. Part of the structure of the connecting piece can pass through the second connecting hole 121a to connect with the first connecting hole 151, thereby connecting the first end 121 and the connecting portion 15.

[0052] The connecting portion 15 may be in an annular structure, and may also be provided with an opening. Alternatively, in some embodiments, the positioning tool 1 may be an integrated structure, such as the positioning tool 1 may be manufactured by 3D printing, injection molding, or other processes.

[0053] Based on the positioning tool 1 described above, this embodiment further provides a method for installing a photovoltaic assembly 2, the method comprising: S1: Install the bonding bracket 3 on the color steel tile 4; In this embodiment, a plurality of adhesive brackets 3 are sequentially mounted on the color steel tile 4 by means of locking members, and the intervals between adjacent adhesive brackets 3 are the same.

[0054] S2: installing two positioning fixtures 1 on two short sides 21 of the photovoltaic component 2 opposite to each other, and the first end 121 of each positioning fixture 1 abuts against the long side 22 of the photovoltaic component 2; In this embodiment, before the photovoltaic assembly 2 is mounted on the bonding bracket 3, the positioning tool 1 is first mounted on the two short sides 21 of the photovoltaic assembly 2. In addition, the first end 121 of the positioning tool 1 is abutted against the long side 22 of the photovoltaic assembly 2 to limit the movement of the positioning tool 1 on the photovoltaic assembly 2.

[0055] S3: placing the photovoltaic module 2 on the bonding bracket 3, and the second end 122 of each positioning tool 1 abuts against the side wall 31 of the bonding bracket 3, and the abutting portion 13 of the positioning tool 1 fits against the adjacent photovoltaic module 2; In this embodiment, the first end 121 abuts against the long side 22 of the photovoltaic component 2, and the second end 122 abuts against the side wall 31 of the adhesive bracket 3, limiting the parallel distance between the long side 22 of the photovoltaic component 2 and the adjacent adhesive bracket 3, so that the parallel distance between the long side 22 of each photovoltaic component 2 and the corresponding adhesive bracket 3 remains fixed, ensuring that the photovoltaic components 2 are installed neatly.

[0056] S4: After the photovoltaic module 2 and the bonding bracket 3 are assembled, the positioning tool 1 is removed from the photovoltaic module 2 for installing the next photovoltaic module 2.

[0057] In this embodiment, after the photovoltaic module 2 is installed, the operator takes the positioning bracket through the hollow area 14 of the positioning bracket and installs the positioning tool 1 to the next photovoltaic module 2 to be installed. Similarly, through a set of positioning tools 1, each photovoltaic module 2 is installed on the bonding bracket 3 in sequence.

[0058] In step S3 , before placing the photovoltaic component 2 on the bonding bracket 3 , the abutment portion 13 first comes into tangential contact with the side wall 31 of the bonding bracket 3 , thereby limiting the direction in which the photovoltaic component 2 falls to the bonding bracket 3 .

[0059] In some embodiments, the photovoltaic assembly 2 includes a first cover plate, a first adhesive film, a battery string group, a second adhesive film, and a second cover plate which are stacked. The battery string group includes a plurality of connected battery strings, and the battery string includes a plurality of electrically connected solar cells.

[0060] The first cover is located on the light-facing side of the battery string, used to transmit sunlight, and also used to improve the waterproof and moisture-proof ability of the photovoltaic module, and seal the battery string together with the second cover. During the lamination process of the photovoltaic module, the first adhesive film and the second adhesive film are used to encapsulate the battery string to prevent the external environment from affecting the performance of the battery string, and at the same time, the first cover, the battery string and the second cover are bonded into a whole.

[0061] The material of the first adhesive film and the second adhesive film can be one of the materials such as ethylene-vinyl acetate copolymer (Ethylene-VinylAcetate Copolymer EVA), polyolefin elastomer (Polyolefin Elastomer POE), polyvinyl butyral (Polyvinyl Butyral PVB), and can also be EPE adhesive film (EVA-POE-EVA co-extrusion structure) or EP adhesive film (EVA-POE co-extrusion structure).

[0062] 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.
