Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, specifically to a positioning fixture for reflective film in the gaps of photovoltaic modules. Background Technology

[0002] Photovoltaic modules are devices that convert solar energy into electrical energy, and reflective film between the gaps is one of the important components of photovoltaic modules. A photovoltaic module is assembled by a backsheet, a glass plate covering the backsheet, and several solar cells located between the two. Reflective film is covered at the gaps between the solar cells. The photovoltaic module uses the reflective film covering the gaps between the solar cells to reflect the light energy that shines on the gaps between the solar cells onto the glass plate, and then reflect it back to the solar cells, so as to make full use of the light energy in the gaps between the solar cells and improve the light energy utilization rate.

[0003] Reflective film reflects sunlight and focuses it onto photovoltaic cells, thereby improving the power generation efficiency of photovoltaic modules. Applying the film is a crucial step in the application of reflective film to photovoltaic modules, and the placement and precision of the film significantly impact the module's power generation efficiency. However, in current photovoltaic module manufacturing processes, the precision of the film application is measured manually against blueprints, which is not only time-consuming and labor-intensive but also prone to errors, affecting the module's power generation efficiency.

[0018] The technical solution of this utility model has the following advantages:

[0019] 1. The photovoltaic module gap reflective film positioning fixture provided by this utility model includes: a positioning base plate, which is made of transparent material and is suitable for covering the upper layer of the reflective film body; a first positioning member, which is disposed on the positioning base plate and is suitable for corresponding to the reflective film body in the first direction; and a second positioning member, which is disposed on the positioning base plate and is suitable for corresponding to the reflective film body in the first direction.

[0020] In use, the positioning base plate is placed above the reflective film body on the photovoltaic module body, so that the first positioning element and the second positioning element are respectively positioned to correspond to the reflective film bodies in the first and second directions. The distance between the reflective film body and the first positioning element in the first direction is measured, adjusted, and determined by visual observation or digital camera photography, and the distance between the reflective film body and the second positioning element in the second direction is measured, adjusted, and confirmed. Since the positions of the first and second positioning elements on the positioning base plate correspond to the positions of the reflective film bodies, after the position of the positioning base plate is determined, the correctness of the adhesive position and spacing of the reflective film bodies can be determined by observing and measuring the relative positions of different reflective film bodies with the first and second positioning elements.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] A photovoltaic module includes multiple solar cells arranged horizontally and vertically. Reflective films are covered at the gaps between the solar cells. In this embodiment, the vertical direction is defined as the first direction, and the horizontal direction is defined as the second direction. That is, the vertically extending reflective film is the reflective film body in the first direction, and the horizontally extending reflective film is the reflective film body in the second direction.

[0032] Figure 1 and Figure 2The present embodiment shows a photovoltaic module gap reflective film positioning fixture, including a positioning base plate 1 and a first positioning component and a second positioning component disposed on the positioning base plate 1.

[0033] The positioning base plate 1 is made of transparent film material and has a certain degree of hardness and flatness, making it suitable for covering the upper layer of the reflective film body. The first positioning element is adapted to correspond to the reflective film body in the first direction; the second positioning element is adapted to correspond to the reflective film body in the second direction.

[0034] When using a positioning fixture to position the reflective film body on the photovoltaic module body, the positioning base plate 1 covers the reflective film body and positions it according to the installation position of the reflective film body on the photovoltaic module. Then, the reflective film body is adjusted so that the reflective film body in the first and second directions corresponds to the first and second positioning parts on the positioning base plate 1, respectively, thus quickly and accurately determining the installation position of the reflective film body on the photovoltaic module.

[0035] In this embodiment, the first positioning member and the second positioning member are perpendicular to each other. Multiple sets of first positioning members are spaced apart, and these sets of first positioning members are parallel to each other. Multiple sets of second positioning members are also spaced apart, and these sets of second positioning members are parallel to each other.

[0036] like Figure 2 As shown, the first positioning component includes a pair of first positioning lines 2, a first positioning area, and a first error line 4. The pair of first positioning lines 2 are parallel to each other, and the area between the pair of first positioning lines 2 constitutes the first positioning area. A pair of first error lines 4 are provided, respectively located on both sides of the first positioning area, with the same spacing between the pair of first error lines 4 and the first positioning area. When positioning the reflective film body in the first direction, the left side of the reflective film body is aligned with the left-side first positioning line, and the right side of the reflective film body is aligned with the right-side first positioning line. To improve the installation efficiency of the reflective film body, the installation position of the reflective film body in the first direction does not exceed the area between the pair of first error lines. The second positioning component includes a pair of second positioning lines 3, a second positioning area, and a second error line 5. The pair of second positioning lines 3 are parallel to each other, and the area between the pair of second positioning lines 3 constitutes the second positioning area. A pair of second error lines 5 are provided, respectively located on both sides of the second positioning area, with the same spacing between the pair of second error lines 5 and the second positioning area. When positioning the reflective film body in the second direction, align the upper side of the reflective film body with the upper second positioning line, and align the lower side of the reflective film body with the lower second positioning line. In order to improve the installation efficiency of the reflective film body, the installation position of the reflective film body in the second direction does not exceed the area between a pair of second error lines.

[0037] The first positioning line 2 and the second positioning line 3 are fabricated on the positioning base plate 1 using laser etching technology. The spacing and position of the first positioning line 2 and the second positioning line 3 correspond to the bonding position and spacing of the reflective film body. The high-precision laser etching process used to fabricate the first positioning line 2 and the second positioning line 3 ensures measurement accuracy while improving measurement efficiency and precision.

[0038] A clearance area 6 is also provided on the positioning base plate 1. No first or second positioning element is provided within the clearance area 6. In this embodiment, the positioning base plate 1 is used to position the installation positions of the upper and lower reflective film bodies. Therefore, no second positioning element is provided within the positioning base plate 1 in this embodiment. Furthermore, to facilitate quick visual identification of the clearance area 6 among the numerous first and second positioning elements, the first positioning elements are intermittently arranged within the clearance area 6, and the clearance area 6 is located in the middle of the positioning base plate 1. A clearance hole 7 is provided within the clearance area 6. The clearance hole 7 is suitable for components such as busbars between adjacent photovoltaic panels on the photovoltaic module body to pass through, ensuring parallelism between the plane of the positioning base plate 1 and the plane of the photovoltaic module body. In use, the end of the reflective film body is suitable for alignment with the clearance hole 7.

[0039] When using a photovoltaic module gap reflective film positioning fixture to position and install the reflective film body on the photovoltaic module, the positioning base plate 1 is placed above the reflective film body on the photovoltaic module, so that the reflective film bodies in the first and second directions correspond to the first and second positioning members, respectively. The positions of the multiple reflective film bodies in the first and second directions are measured and adjusted sequentially by visual observation or digital camera photography. Since the positions and spacing of the first and second positioning members correspond to the pasting positions and spacing of the reflective film bodies, the measurement results can be used to determine whether the pasting positions and spacing of the reflective film bodies are correct.

[0040] The positioning base plate 1 allows for quick and accurate confirmation of the reflective film's adhesion position and spacing, avoiding the time-consuming, labor-intensive, and error-prone problems of traditional film-adhesion accuracy measurement methods. It enables timely detection of the reflective film's adhesion position and accuracy, thus preventing production capacity losses due to random sampling. Furthermore, the positioning base plate 1 has a low manufacturing cost, allowing for large-scale use and avoiding issues such as insufficient measurement accuracy and high material costs in precision measurement and thin-film material technology fields. By adopting these technologies, the accuracy of the reflective film's adhesion position and precision can be ensured, thereby improving the efficiency and accuracy of accuracy confirmation, ultimately increasing the power generation efficiency of photovoltaic modules, reducing production costs, and enhancing enterprise competitiveness.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
