Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaics, in particular to a packaging frame and a photovoltaic component. Background Art
[0002] In the photovoltaic industry, the upstream and downstream are divided into silica, metal silicon, polysilicon, silicon rods, silicon wafers, solar cells, photovoltaic modules, arrays, power station systems, etc. The power station system is composed of photovoltaic modules, foundations, brackets, junction boxes, inverters, box transformers and then power grids. Therefore, there are many factors that affect the power of the power generation system. Photovoltaic modules are the only source of power generation. The intensity of solar radiation, spectral characteristics, radiation angle and climate are all factors that affect the power generation of photovoltaic modules. The environment and climate are objective facts that humans cannot change. Therefore, the structure of the photovoltaic module itself has become an option to improve photovoltaic efficiency.
[0003] Photovoltaic modules have a certain life cycle. For photovoltaic modules that have reached the end of their life cycle, the frames are recyclable products. In addition, during the production process of photovoltaic modules, there will inevitably be defective products. The frames of defective products can also be recycled. At present, the framing of photovoltaic modules is done by applying silicone in the groove of the frame, which is then solidified, making it difficult to disassemble the frame. At the same time, the frame will be damaged and deformed during the disassembly process. Utility Model Content
[0004] Based on this, it is necessary to provide a packaging frame. When the packaging frame of the utility model is used for photovoltaic module packaging, no glue is needed, the amount of silicone used is reduced, the frame is easy to install, the installation steps are simple, and the production efficiency is improved. For photovoltaic modules with poor process, the frame is easy to remove and will not deform, reducing losses. For photovoltaic modules that have expired, the frame and the sealing airbag can be disassembled and recycled for continued use when recycling, achieving the purpose of saving costs.
[0005] An embodiment of the present application provides a packaging frame.
[0006] A packaging frame includes a frame body and a sealing airbag, wherein the sealing airbag is elastic and can be inflated and expanded, and is arranged in a mounting groove of the frame body. The sealing airbag is used to wrap the edge position of a solar cell to achieve installation connection between the solar cell and the frame body.
[0007] In some of the embodiments, the sealing airbag is an integral annular structure.
[0008] In some embodiments, the sealing airbag satisfies at least one of the following conditions:
[0009] (1) Rupture force ≥ 10N;
[0010] (2) Extension ≥ 55N;
[0011] (3) Transverse elongation at break ≥ 400%, longitudinal elongation at break ≥ 300%;
[0012] (4) Longitudinal breaking force ≥ 7N, transverse breaking force ≥ 3.5N;
[0013] (5) Water vapor transmission rate ≤18t / (g / ㎡·24h);
[0014] (6) Shore hardness (A) is 50~70.
[0015] In some of the embodiments, the thickness of the sealing airbag is 1 mm to 5 mm.
[0016] In some of the embodiments, the sealing airbag is a rubber airbag, an aluminum film latex airbag, a plastic airbag, an Oxford cloth airbag, a PVC airbag, an aluminum foil airbag, a PA airbag or a PE airbag.
[0017] In some embodiments, the frame body is a metal frame.
[0018] An embodiment of the present application also provides a photovoltaic module.
[0019] A photovoltaic assembly comprises a solar cell and a packaging frame, wherein the solar cell is packaged in a mounting groove of the packaging frame through a sealing air bag.
[0020] In some embodiments, the length L1 of the sealed airbag wrapped around the light-receiving surface of the solar cell is 6 mm to 12 mm.
[0021] In some embodiments, the length L2 of the sealed airbag wrapped around the backlight surface of the solar cell is 6 mm to 14 mm.
[0022] In some embodiments, one end of the sealing airbag located on the backlight surface of the solar cell protrudes from the mounting groove, and a length L3 of the sealing airbag protruding from the mounting groove is 1 mm to 5 mm.
[0023] The above-mentioned packaging frame is installed with a solar cell by setting an inflatable sealing airbag. After inflation, the sealing airbag wraps the edge of the solar cell, replacing the sealant in the traditional technology. The sealing airbag plays a sealing role. At the same time, the sealing airbag can support the frame body after expansion, which has the effect of increasing mechanical strength and waterproofing. When the photovoltaic components expire, the frame and the sealing airbag can be disassembled and recycled for continued use, achieving the purpose of saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

For example, please refer to Figure 1, which is a schematic diagram of the structure of the packaging frame 100 provided in an embodiment of the present application.
[0043] A packaging frame 100 includes a frame body 110 and a sealing airbag 120. The sealing airbag 120 is elastic and can be inflated.

[0050] (5) Water vapor permeability ≤18t / (g / ㎡·24h).
[0051] (6) Shore hardness (A) is 50~70.
[0052] In some of the embodiments, the thickness of the sealing airbag 120 is 1 mm to 5 mm. For example, in one specific example, the thickness of the sealing airbag 120 is 1 mm. In another specific example, the thickness of the sealing airbag 120 is 5 mm.
[0053] In some embodiments, the material of the sealing airbag 120 is rubber, aluminum film latex, plastic, Oxford cloth, PVC, aluminum foil, PA or PE. Correspondingly, the sealing airbag 120 is a rubber airbag, an aluminum film latex airbag, a plastic airbag, an Oxford cloth airbag, a PVC airbag, an aluminum foil airbag, a PA airbag or a PE airbag.
[0054] The sealing airbag 120 is in the shape of a long closed ring structure. The sealing airbag 120 is not allowed to have bubbles, perforations, ruptures, impurities, and dead blocks. When not inflated, the sealing airbag 120 is stretched and wrapped around the edges of the solar cell 200 using its retractable characteristics, and then the packaging frame 100 is installed.
[0055] In some embodiments, the frame body 110 is a metal frame, for example, an aluminum alloy metal frame.
[0056] An embodiment of the present application further provides a photovoltaic assembly 10 .
[0057] A photovoltaic assembly 10, as shown in FIG4 , includes a solar cell 200 and a packaging frame 100. The solar cell 200 is packaged in a mounting groove 101 of the packaging frame 100 through a sealing airbag 120.
[0058] In some embodiments, as shown in FIG1 , the length L1 of the sealed airbag 120 wrapped around the light-receiving surface of the solar cell 200 is 6 mm to 12 mm. For example, in one specific example, the length L1 of the sealed airbag 120 wrapped around the light-receiving surface of the solar cell 200 is 6 mm. In another specific example, the length L1 of the sealed airbag 120 wrapped around the light-receiving surface of the solar cell 200 is 12 mm.
[0059] In some embodiments, as shown in FIG1 , the length L2 of the sealed airbag 120 wrapped around the backlight surface of the solar cell 200 is 6 mm to 14 mm. For example, in one specific example, the length L2 of the sealed airbag 120 wrapped around the backlight surface of the solar cell 200 is 6 mm. In another specific example, the length L2 of the sealed airbag 120 wrapped around the backlight surface of the solar cell 200 is 14 mm.

For example, in one specific example, the length L3 of the sealing airbag 120 protruding from the mounting groove 101 is 1 mm. In another specific example, the length L3 of the sealing airbag 120 protruding from the mounting groove 101 is 5 mm.
[0061] In the present application, when installing the solar cell 200, the uninflated sealed airbag 120 is stretched and evenly covered on the edges of the solar cell 200 from top to bottom, and then the frame body 110 is installed on the outer layer of the sealed airbag 120, and the sealed airbag 120 is inflated through the air nozzle reserved on the sealed airbag 120. The inflated sealed airbag 120 expands and plays the role of fixing the solar cell 200 and the frame body 110. When it is necessary to disassemble the sealed airbag 120, the air is released through the air nozzle to separate the solar cell 200 from the frame body 110, and the frame body 110 and the sealed airbag 120 are recovered.
[0062] It should be noted that, in the present application, the above-mentioned numerical interval (i.e., numerical range) is involved. If not otherwise specified, the distribution of the optional numerical values in the numerical interval is considered 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. If not otherwise specified, when the numerical interval only refers to the integers in 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 combined. In other words, unless otherwise specified, the numerical range 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.
[0063] To summarize, the above-mentioned packaging frame 100 installs the solar cell 200 by setting an inflatable sealing airbag 120. After inflation, the sealing airbag 120 wraps the edge of the solar cell 200, replacing the sealant in traditional technology. The sealing airbag 120 can not only play a sealing role, but also support the frame body 110 after the sealing airbag 120 is expanded, thereby increasing the mechanical strength and waterproofing effect. When the solar cell 200 reaches the end of its service life or is damaged and cannot be used, the sealing airbag 120 can be disassembled to achieve the separation of the packaging frame 100 and the solar cell 200, thereby realizing the recycling of the packaging frame 100 and the sealing airbag 120.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
