Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a positioning connector. Background Art

[0002] In the existing photovoltaic module production process, the battery cells are connected by welding strips to form a battery string. Multiple battery strings are arranged in series and laminated in the semi-finished module. During the lamination process, positioning connectors are required to position each battery string. During the use of the positioning connectors, bulging bubbles often appear. The formation of bubbles will affect the reliability and appearance of the photovoltaic module. For the above problems, the existing technology has a solution of using perforated tape. Although the perforated tape can discharge gas well during use, it is easy to be torn off. When the perforated tape is torn off, manual intervention and adjustment are required, which will have an adverse effect on the process rhythm of the photovoltaic module. Utility Model Content

[0036] In some embodiments, the base layer 100 is in a long strip structure, and the base layer 100 is bent toward the middle at two sides along its length direction.

[0037] In some embodiments, as shown in Fig. 1, the base layer 100 is curved. The adhesive layer 200 is not shown in Fig. 1. It should be noted that when the base layer 100 is curved, it can be a single arch structure or multiple wavy structures.

[0042] In some embodiments, the thickness of the base layer 100 is 30 μm to 200 μm. For example, in one specific example, the thickness of the base layer 100 is 30 μm; in another specific example, the thickness of the base layer 100 is 200 μm; it is not difficult to understand that in other specific examples, the thickness of the base layer 100 can also be 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, 100 μm, 120 μm, 150 μm, 160 μm, 190 μm or other parameter values.

[0044] In some of the embodiments, please refer to FIG. 3, which is a partial structural schematic diagram of the positioning connector 10 provided in the embodiment of the present application, and the number of the adhesive layer 200 is multiple. The multiple adhesive layers 200 are spaced and distributed on the first surface along the length direction of the base layer 100. The number of adhesive layers 200 can be adaptively set according to the length of the base layer 100 and the length of the adhesive layer 200. Referring to FIG. 4, FIG. 4 is a partial structural schematic diagram of the positioning connector 10 of another embodiment of the utility model.

[0045] In some embodiments, the length of the adhesive layer 200 along the length direction of the base layer 100 is 1 mm to 5 mm. For example, in one specific example, the length of the adhesive layer 200 along the length direction of the base layer 100 is 1 mm; in another specific example, the length of the adhesive layer 200 along the length direction of the base layer 100 is 5 mm; it is not difficult to understand that in other specific examples, the length of the adhesive layer 200 along the length direction of the base layer 100 can also be 2 mm, 3 mm, 4 mm or other parameter values.

[0046] In some embodiments, the width of the adhesive layer 200 along the width direction of the base layer 100 is equal to the width of the base layer 100 .

[0047] In some embodiments, the spacing between adjacent adhesive layers 200 is 5 μm to 10 μm. For example, in one specific example, the spacing between adjacent adhesive layers 200 is 5 μm; in another specific example, the spacing between adjacent adhesive layers 200 is 10 μm; it is not difficult to understand that in other specific examples, the spacing between adjacent adhesive layers 200 can also be 6 μm, 7 μm, 8 μm, 9 μm or other parameter values.

[0048] In the present application, a spacing of 5 μm to 10 μm is set between adjacent adhesive layers 200. The setting of this spacing can ensure that there is a certain amount of accommodation space for bubbles generated by adjacent adhesive layers 200. Even if bubbles are generated on the adhesive layer 200, part of the gas can flow into the gap between the adjacent adhesive layers 200. During lamination, no lamination bubbles will be generated on the adhesive layer 200.

[0049] It should be noted that, in the present application, when it comes to numerical intervals (i.e., numerical ranges), unless otherwise specified, the distribution of optional numerical values ​​within the numerical interval is deemed to be continuous, and includes the two numerical endpoints (i.e., the minimum value and the maximum value) of the numerical interval, and each numerical value between the two numerical endpoints. Unless otherwise specified, when the numerical interval only refers to integers within the numerical interval, it includes the two endpoint integers of the numerical range, and each integer between the two endpoints, which is equivalent to directly listing each integer. When multiple numerical ranges are provided to describe features or characteristics, these numerical ranges can be merged. In other words, unless otherwise specified, the numerical ranges disclosed in the present application should be understood to include any and all sub-ranges included therein. The "numerical value" in the numerical interval can be any quantitative value, such as a number, a percentage, a ratio, etc. "Numerical interval" allows for broadly including quantitative intervals such as percentage intervals, ratio intervals, and ratio intervals.

[0050] In some of the embodiments, it should be noted that the adhesive layer 200 may be in a regular long strip structure or in a parallelogram shape.

[0051] In some embodiments, the positioning connector 10 further includes a reel 300. The periphery of the reel 300 is inwardly concave, so that it can adapt to the convex structure of the first surface of the base layer 100, which facilitates the winding of the base layer 100. After being processed and produced, the base layer 100 and the adhesive layer 200 are wound on the reel 300.

[0052] In some of the embodiments, the length of the base layer 100 of the present application can be set according to actual needs.

[0053] It should be noted that the positioning connector 10 in the present application can be used in the lamination positioning process of the photovoltaic module, and can also be used as a common positioning tape.

[0054] To summarize, the positioning connector 10 is configured to bend the base layer 100 so that the first surface of the base layer 100 is convex, the second surface of the base layer 100 is concave, and the adhesive layer 200 on the first surface is also convex. When the positioning connector 10 is pasted on the laminate, the convex adhesive layer 200 is gradually smoothed, thereby avoiding the generation of lamination bubbles to a great extent, increasing the yield rate of photovoltaic modules, and improving the reliability and aesthetics of photovoltaic modules.
