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 field, photovoltaic modules are generally installed at an angle of 5°~45° facing south. After installation, the convexity of the frame at the lower edge of the photovoltaic module is 3-5mm higher than the front glass plate. In some outdoor dusty areas, dust is easily accumulated at the lower edge of the front glass plate of the photovoltaic module. Dust accumulation not only affects the power generation of the photovoltaic module, but also causes hot spot effect, resulting in the risk of failure of the photovoltaic module. For example, for frames without A-side design, when using negative pressure blocks for installation, rubber blocks are generally embedded in the metal negative pressure blocks. The compression of the rubber blocks generates extrusion and friction to hold the glass of the photovoltaic module. However, when the photovoltaic module is under negative pressure, the extrusion friction of the rubber block may be low, causing the negative pressure block to fall off and the photovoltaic module installation to fail.

[0035] The embodiment of the present application provides a packaging frame 10 to solve the problem that in the traditional technology, after the photovoltaic module is installed at an angle of 5° to 45° facing south, dust is easily accumulated at the lower edge of the front glass plate of the photovoltaic module, which not only affects the power generation of the photovoltaic module but also causes the hot spot effect and leads to the risk of failure of the photovoltaic module; and for the frame without A-side design, when a negative pressure block is used for installation, the rubber extrusion friction on the negative pressure block may be low, and the negative pressure block may fall off, resulting in the failure of the photovoltaic module installation. The packaging frame 10 will be described below in conjunction with the accompanying drawings.

[0036] The packaging frame 10 provided in the embodiment of the present application is exemplary, see Figure 1 As shown, Figure 1 The schematic diagram of the structure of the packaging frame 10 provided in the embodiment of the present application is as follows. The packaging frame 10 of the present application can be used for photovoltaic purposes, and can be specifically used for photovoltaic module installation purposes.

[0037] In order to more clearly illustrate the structure of the packaging frame 10 , the packaging frame 10 will be introduced below with reference to the accompanying drawings.

[0038] For example, see Figure 1 As shown, Figure 1 The schematic diagram of the structure of the packaging frame 10 provided in the embodiment of the present application is as follows: The packaging frame 10 includes a frame body 100 and a stopper 200.

[0039] The frame body 100 has an angle code cavity 101 for embedding and connecting the angle code. One side edge of the limiting member 200 is connected to the outer surface of the first side wall 110 of the frame body 100. An installation area 400 for installing the solar cell 20 is formed between the limiting member 200 and the first side wall 110 of the frame body 100. The surface of the limiting member 200 facing the installation area 400 forms an abutment surface. The side of the abutment surface away from the frame body 100 has an abutment portion 210 extending toward the installation area 400. The end surface of the abutment portion 210 away from the frame body 100 has a serrated structure 212, and the serrated structure 212 can engage with the block serrations 301 of the negative pressure block 300. The surface of the first side wall 110 of the frame body 100 located in the installation area 400 forms a bearing surface 111. Wherein, see Figure 2 As shown, Figure 2This is a schematic diagram of the cooperation between the packaging frame 10 and the solar cell 20 according to an embodiment of the utility model. The bearing surface 111 is used to support a portion of the back surface of the solar cell 20 , and the abutting portion 210 is used to abut at least a portion of the end surface of the solar cell 20 .

[0040] In the frame assembly of the present application, the bearing surface 111 is used to support the back of the solar cell 20, and the abutment portion 210 is used to abut the end face of the solar cell 20, so as to achieve the installation and fixation of the solar cell 20. After the photovoltaic assembly is installed at an inclination angle of 5°~45°, the dust and rainwater on the glass surface of the solar cell 20 can be quickly detached along the outer surface of the abutment portion 210, and the abutment portion 210 will not block the dust on the glass surface of the solar cell 20, so that the glass surface of the solar cell 20 is not easy to accumulate dust and water.

[0041] In some embodiments, the bearing surface 111 has a glue storage tank 1101 for accommodating the connecting component 500. The above-mentioned glue storage tank 1101 is used to fill the connecting component 500. The connecting component 500 can be a structural glue, an adhesive or other adhesive material to achieve bonding with the solar cell 20.

[0042] In some embodiments, there are multiple glue storage slots 1101 on the carrying surface 111. The multiple glue storage slots 1101 are distributed at intervals.

[0043] In some embodiments, the depth of the glue storage tank 1101 is 0.3 mm to 0.5 mm. The depth of the glue storage tank 1101 should not be too large or too small. If the depth of the glue storage tank 1101 is too large, it will cause a large amount of structural glue, adhesive or other adhesive materials to be used, resulting in material waste. If the depth of the glue storage tank 1101 is too small, the bonding effect of the structural glue, adhesive or other adhesive materials will be poor, and the solar cell 20 cannot be effectively fixed.

[0044] In some embodiments, the inner wall of the glue storage tank 1101 gradually narrows from the bottom surface to the groove opening. The glue storage tank 1101 is a urn-shaped structure with a small mouth and a large belly. The structural glue, adhesive or other adhesive material has fluidity and can be filled in the glue storage tank 1101. After curing, the glue storage tank 1101 can better hold the cured structural glue, adhesive or other adhesive material to enhance the bonding effect of the solar cell 20.

[0045] In some embodiments, the bearing surface 111 gradually tilts inward at an angle α of 3° to 7° from the side away from the limiting member 200 to the side adjacent to the limiting member 200. Figure 1The angle between the two dotted lines in the figure, wherein the gradually inward inclination at an angle α of 3° to 7° means that the side of the bearing surface 111 close to the inside is concave inward. The inward inclination of the bearing surface 111 facilitates the smoother assembly process of the solar cell 20 with the frame body 100, avoids the solar cell 20 from hitting the bearing surface 111 of the frame body 100, and reduces the collision and damage of the solar cell 20. Since the bearing surface 111 is inclined inward, when the back of the solar cell 20 contacts the bearing surface 111, the angle α between the back of the solar cell 20 and the bearing surface 111 is 3° to 7°.

[0046] In some embodiments, the middle position of the limiter 200 is bent away from the installation area 400, so that the concave curved surface of the abutment surface forms a glue overflow groove 201, and the glue overflow groove 201 is used to accommodate the connecting component 500. The glue overflow groove 201 is used to store the connecting component 500. The connecting component 500 can be a structural glue, an adhesive or other adhesive material, and the connecting component 500 realizes the connection between the first limiter and the end face of the solar cell 20. In addition, the limiter 200 has a curved structure that can play a buffering role. After the solar cell 20 is assembled into the installation area 400, when the end face of the solar cell 20 contacts the abutment portion 210 of the limiter 200, it has a buffering effect, thereby reducing the damage to the solar cell 20.

[0047] In some embodiments, the outer surface of the abutting portion 210 is provided with an adhesive groove 211 for accommodating the connecting component 500. After the abutting portion 210 abuts against the end surface of the solar cell 20, it can prevent the connecting component 500 such as structural glue, adhesive or other adhesive materials from overflowing from the adhesive groove 201. The adhesive groove 211 is filled with structural glue, adhesive or other adhesive materials to improve the bonding force between the abutting portion 210 and the solar cell 20.

[0048] In some embodiments, the maximum height of the stopper 200 along the direction perpendicular to the bearing surface 111 is not greater than the thickness of the solar cell 20. Figure 2 As shown, the maximum height of the limiting member 200 along the direction perpendicular to the carrying surface 111 is slightly equal to the thickness of the solar cell 20 .

[0049] In some of these embodiments, see Figure 3 As shown, Figure 3 FIG. 1 is a schematic diagram of a negative pressure block structure of a packaging frame according to an embodiment of the present invention. The packaging frame 10 further includes a negative pressure block 300. The negative pressure block 300 has a block sawtooth 301. The negative pressure block 300 is also provided with a block slot 302. Figure 4 As shown, Figure 4Schematic diagram of the cooperation between the packaging frame and the negative pressure block according to an embodiment of the utility model. The block teeth 301 are used to engage with the serrated structure 212 on the abutment portion 210. The block slot 302 is used to connect the rubber block 303. The rubber block 303 is used to abut against part of the front surface of the solar cell 20.

[0050] In some of these embodiments, please refer again to Figure 3 As shown, the negative pressure block 300 includes a first block arm 311, a second block arm 312, a third block arm 313, and a fourth block arm 314, wherein the first block arm 311, the second block arm 312, the third block arm 313, and the fourth block arm 314 are connected in sequence, the first block arm 311 is perpendicular to the second block arm 312, the third block arm 313 is perpendicular to the second block arm 312, the third block arm 313 and the first block arm 311 extend in opposite directions, the fourth block arm 314 is perpendicular to the third block arm 313, and the fourth block arm 314 and the second block arm 312 extend in opposite directions. During lamination, the third pressing block arm 313 abuts against the stopper 200 of the packaging frame 10, and the fourth pressing block arm 314 is used to cover and abut against the front of the solar cell 20, and the fourth pressing block arm 314 has a pressing block serration 301 and a pressing block slot 302, the pressing block serration 301 is engaged with the serrated structure 212 on the stopper 200, and a rubber block 303 is connected in the pressing block slot 302, and a part of the rubber block 303 abuts against the front of the solar cell 20. The negative pressure pressing block 300 is used to assist the lamination process of the solar cell 20.

[0051] In some of these embodiments, see Figure 3 As shown, the end of the first pressing block arm 311 is also provided with saw teeth, which can cooperate with the external fixing seat to fix the entire negative pressure pressing block 300.

[0052] In some of these embodiments, see Figure 1 As shown, the frame body 100 is a hollow quadrangular prism structure. The frame body 100 includes a first side wall 110, a second side wall 120, a third side wall 130 and a fourth side wall 140. The first side wall 110, the second side wall 120, the third side wall 130 and the fourth side wall 140 are connected in sequence. The stopper 200 is connected to the outer surface of the first side wall 110. Preferably, the first side wall 110 is parallel to the third side wall 130. The first side wall 110 is perpendicular to the second side wall 120, the second side wall 120 is parallel to the fourth side wall 140, and the third side wall 130 is perpendicular to the fourth side wall 140.

[0053] In some embodiments, at least one of the inner surface of the first side wall 110, the inner surface of the second side wall 120, the inner surface of the third side wall 130 and the inner surface of the fourth side wall 140 is connected with a plurality of reinforcing ribs 150. The provision of the reinforcing ribs 150 can increase the structural strength of the frame body 100.

[0054] In some of these embodiments, preferably, see Figure 1 As shown, a plurality of reinforcing ribs 150 are respectively connected to the inner surface of the first side wall 110 and the inner surface of the third side wall 130 .

[0055] In some embodiments, the height of the reinforcing rib 150 is 0.3 mm to 0.5 mm.

[0056] In some of these embodiments, see Figure 1 As shown, a support plate 160 is connected at the corner between the second side wall 120 and the third side wall 130. The support plate 160 extends away from the frame body 100 along the plane where the third side wall 130 is located.

[0057] In some embodiments, the frame body 100 is made of aluminum alloy, and the length of the frame body 100 is 1100 mm to 2400 mm. The frame body 100 of aluminum alloy has the advantages of high strength, strong firmness, good electrical conductivity, corrosion resistance and oxidation resistance, strong tensile strength, convenient transportation and installation, and easy recycling. The rigidity and strength of the aluminum alloy increase the mechanical strength and electrical conductivity of the frame body 100, which is conducive to installation and grounding.

[0060] In some embodiments, when encapsulating the solar cell 20, the number of the encapsulation frames 10 may be multiple. Different encapsulation frames 10 may have different lengths.

[0061] In summary, the packaging frame 10 of the present application has good load and frame overflow effects, which can reduce the dust accumulation effect of the photovoltaic module and improve the power generation of the photovoltaic module. At the same time, it can also reduce the hot spot effect and lower the working temperature of the photovoltaic module.
