Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to an anti-dust accumulation photovoltaic component and a frame fixing structure thereof. Background Art

[0002] The frames of existing photovoltaic modules generally include a top edge (also called A side), a side edge (also called B side) and a bottom edge (also called C side), which wrap the edges of the light-receiving surface, side surfaces and backlight surface of the module body.

[0003] Existing anti-dust photovoltaic modules are usually obtained by removing the A side of the existing frame. Since the A side is removed, the existing framing machines cannot solve the problem of glue overflow. The photovoltaic modules need to be installed with the front side facing up, and the framing equipment needs to be modified. In addition, the amount of glue is difficult to control. Too much glue is wasted and the overflowed glue needs to be wiped off. If there is too little glue, the frame and the side of the module cannot form a complete seal, and water accumulation may form later, leading to the risk of edge delamination and failure. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a dust-proof photovoltaic module, which does not require modification of framing equipment and can be installed using a frame like an existing photovoltaic module.

[0005] The technical solution adopted by the utility model to solve the technical problem is: an anti-dust accumulation photovoltaic component, comprising:

[0006] The component body is rectangular and includes two side edges in the first direction and two side edges in the second direction;

[0007] A first-direction frame, the first-direction frame is bonded to the first-direction side edge of the component body, the first-direction frame is an L-shaped frame, the L-shaped frame includes a frame bottom edge located on the backlight surface of the component body and a frame side edge located on the side of the component body, the frame side edge is flush with the light-receiving surface of the component body, or the frame side edge is lower than the light-receiving surface of the component body;

[0008] The second direction frame is bonded to the second direction side of the component body, the second direction frame has a frame slot, the second direction side of the component body is clamped in the frame slot, the second direction frame has a corner code slot below the frame slot, the inner side of the corner code slot has a corner code clamping slot, and both ends of the frame slot have a clearance gap. The two ends of the first direction frame are inserted into the frame slot of the second direction frame through the clearance gap to form a rectangular frame structure with the second direction frame.

[0009] In some embodiments, optionally, the component body is a rectangular component body, the side in the first direction is a short side of the component body, and the side in the second direction is a long side of the component body.

[0010] In some embodiments, optionally, the second direction frame has a mounting structure for adapting to the installation of photovoltaic components.

[0011] A frame fixing structure of the above-mentioned anti-dust accumulation photovoltaic component includes an anti-dust accumulation photovoltaic component, a corner code and a fixed frame, the two ends of the corner code are respectively a first end and a second end, the inner side of the first end of the corner code has a protruding buckle, which is used to be snap-connected with the corner code bayonet of the second direction frame, the fixed frame has a corner code groove, and there are two fixed frames, which are located on both sides of the first direction of the component body, and the corner codes are located at the corners of the fixed frame and the second direction frame. The first end of the corner code is inserted into the corner code groove of the second direction frame, and the second end of the corner code is inserted into the corner code groove of the fixed frame, which is used to connect the fixed frame and the second direction frame together to form a rectangular frame structure.

[0015] In some embodiments, optionally, the fixed border is lower than the first direction border.

[0016] The beneficial effects of the present invention are as follows: the first direction frame adopts an L-shaped frame, which can be put into the laminator for laminated together with the laminate of the component body.

DETAILED DESCRIPTION

[0032] like Figures 1 to 13 As shown, a dust-accumulation-proof photovoltaic module comprises:

[0033] The component body 1 is rectangular and includes two first-direction side edges and two second-direction side edges;

[0034] A first-direction frame 2, which is bonded to the first-direction side of the component body 1. The first-direction frame 2 is an L-shaped frame. The L-shaped frame includes a frame bottom edge 2-1 located on the backlight side of the component body 1 and a frame side edge 2-2 located on the side of the component body 1. The frame side edge 2-2 is flush with the light-receiving surface of the component body 1, or the frame side edge 2-2 is lower than the light-receiving surface of the component body 1.

[0035] The second direction frame 3 is bonded to the second direction side of the component body 1, and the second direction frame 3 has a frame slot 3-1. The second direction side of the component body 1 is stuck in the frame slot 3-1. The frame slot 3-1 of the second direction frame 3 has a corner code slot 4 below, and the inner side of the corner code slot 4 has a corner code slot 5. The two ends of the frame slot 3-1 have a clearance gap 6. The two ends of the first direction frame 2 are inserted into the frame slot 3-1 of the second direction frame 3 through the clearance gap 6, forming a rectangular frame structure with the second direction frame 3.

[0036] like Figures 3-5 As shown, the second direction frame 3 is similar to the conventional component frame, with the difference that: the two ends of the second direction frame 3 are right angles and no corner cutting is performed. The two ends of the first direction frame 2 are adapted in the frame grooves 3-1 at the two ends of the second direction frame 3, and are partially enlarged to form a clearance gap 6. The two ends of the first direction frame 2 are inserted into the frame groove 3-1 of the second direction frame 3 through the clearance gap 6.

[0037] The second direction frame 3 has an installation structure for adapting to the installation of photovoltaic components.

[0038] like Figure 1 and 2 As shown, the inner side surface of the frame bottom edge 2-1 of the first direction frame 2 has a glue overflow groove 10 to increase the bonding strength between the first direction frame 2 and the component body 1. Of course, the glue overflow groove 10 can also be set on the inner side surface of the frame side edge 2-2, or the inner side surfaces of the frame side edge 2-2 and the frame bottom edge 2-1 have glue overflow grooves 10. The height of the inner side surface of the frame side edge 2-2 is slightly less than the total thickness of the laminate material of the component body 1. After the laminate and the first direction frame 2 enter the laminating machine for lamination, the laminate is laminated to form the component body 1, and the thickness is reduced.

[0039] The existing framing machines and production lines of component production lines without A-side frames need to be modified, while the first direction frame 2 of the short side of the photovoltaic component of the utility model adopts an L-shaped frame, which can be laminated together with the laminate of the component body 1 in the laminator. The overflowing packaging material during lamination will bond the first direction frame 2 and the laminate together. Since the laminator table has good flatness, the frame side 2-2 of the first direction frame 2 is basically flush with the light-receiving surface of the component body 1, achieving an anti-dust accumulation effect, and the framing machine and production line do not need to be modified.

[0040] Existing non-A-side frames use silicone adhesive, but the amount of glue between the frame and the module body 1 is difficult to control. Excessive glue is wasted and requires cleaning, while insufficient glue can easily lead to delamination between the frame and the module body 1. However, the first-direction frame 2 of the short side of the photovoltaic module of the present invention adopts an L-shaped frame. This can be laminated together with the laminate of the module body 1 in a laminator. During lamination, the overflowing encapsulation material bonds the first-direction frame 2 and the laminate together, eliminating the need for glue.

[0041] like Figures 11-13 As shown, a frame fixing structure of the above-mentioned anti-dust accumulation photovoltaic component includes an anti-dust accumulation photovoltaic component, a corner code 7 and a fixed frame 8, the two ends of the corner code 7 are respectively a first end and a second end, the inner side of the first end of the corner code 7 has a protruding buckle 9, which is used to be snap-connected with the corner code bayonet 5 of the second direction frame 3, the fixed frame 8 has a corner code groove 4, there are two fixed frames 8, which are located on both sides of the first direction of the component body 1, the corner code 7 is located at the corner of the fixed frame 8 and the second direction frame 3, the first end of the corner code 7 is detachably inserted into the corner code groove 4 of the second direction frame 3, and the second end of the corner code 7 is inserted into the corner code groove 4 of the fixed frame 8, which is used to connect the fixed frame 8 and the second direction frame 3 together to form a rectangular frame structure.

[0042] like Figure 7 and 8 As shown, the fixed frame 8 is a rectangular tube. Preferably, the fixed frame 8 is lower than the first direction frame 2 so that the fixed frame 8 does not contact the first direction frame 2.

[0043] The inner side of the corner code slot 4 of the fixed frame 8 also has a corner code socket 5 , and the inner side of the second end of the corner code 7 also has a protruding buckle 9 for being snap-connected with the corner code socket 5 of the fixed frame 8 .

[0044] Preferably, the front outer side of the first end of the angle code 7 has a clearance notch 6, which is used to allow the front part of the first end of the angle code 7 to be elastically deformed outward. The buckle 9 on the first end of the angle code 7 is located at the front of the first end. The first end of the angle code 7 is detachably connected to the second direction frame 3. The second end of the angle code 7 is substantially the same size as the angle code slot 4 of the fixed frame 8, so that the second end of the angle code 7 is non-detachably connected to the fixed frame 8.

[0045] The corner code 7 is L-shaped and is made of aluminum, composite material or plastic.

[0046] The purpose of installing the fixed frame 8 is to facilitate the transportation of photovoltaic modules on the assembly line. Installing the fixed frame 8 for temporary fixation is also beneficial to the framing of the second direction frame 3 and the curing of the silicone in the frame groove 3-1. After the silicone in the second direction frame 3 is initially cured, the fixed frame 8 can be removed, and then subsequent testing and packaging for shipment can be carried out.

[0047] Of course, when used together, it is desirable to maintain the fixed frame 8 in place to enhance the strength of the frame structure surrounding the module body 1. When the fixed frame 8 does not need to be removed, the first and second ends of the corner brackets 7 can be designed to be identical, non-removable. The module body 1 of a rectangular, dust-proof photovoltaic module is rectangular, with the first side being the short side of the module body 1 and the second side being the long side of the module body 1.

[0048] The following uses a rectangular anti-dust photovoltaic module as an example to illustrate the preparation process of the anti-dust photovoltaic module as follows:

[0049] 1. Pre-install the first-direction frame 2 on the short side of the laminate and temporarily fix it with tape. Then, put the first-direction frame 2 and the laminate into the laminator for lamination. During the lamination process, the packaging material inside the laminate overflows and bonds the first-direction frame 2 and the component body 1 together.

[0050] 2. After lamination is completed, the framing process begins: first, glue is applied to the frame notch 3-1 of the second-direction frame 3, and then the second-direction frame 3 is framed with the first-direction frame 2. The two ends of the first-direction frame 2 are inserted into the frame notch 3-1 of the second-direction frame 3 through the clearance notch 6, and the second-direction side of the component body 1 is stuck in the frame notch 3-1;

[0051] 3. Use the corner code 7 to assemble the fixed frame 8 and the second direction frame 3 together to form a temporary rectangular frame structure. The corner code 7 and the fixed frame 8 are non-detachable, and the corner code 7 and the second direction frame 3 are detachable. After the silicone in the frame notch 3-1 is cured, the connection between the corner code 7 and the second direction frame 3 can be loosened by squeezing the corner code 7 inward from the corner code socket 5 of the second direction frame 3, and the fixed frame 8 can be removed. The fixed frame 8 with the corner code 7 can be recycled in the production line, which can save the cost of the fixed frame.
