Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a photovoltaic component. Background Art

[0002] A certain amount of silicone sealant is usually pre-injected or reserved in the frame of a photovoltaic module. The purpose is to provide a seal after the laminate is installed in place to prevent moisture and gas penetration and enhance the structural stability of the module. After the laminate is inserted into the frame notch, if too much silicone is used or the pressure applied during the framing process is uneven, the silicone will squeeze out of the gap in the frame, resulting in overflow of glue on the front of the module.

[0003] The existing technology usually designs one or more glue storage and overflow structures on the frame, but there is still a problem of front glue overflow during the automatic framing process of the production line, especially the front glue overflow at the joint of the long and short frames. Manual cleaning of the overflow glue is required, which seriously affects the online production capacity. And the sharp corners can easily cause scratches. Lightweight components have a more serious problem of frame overflow glue due to their own material problems, the laminated parts are soft, and there is warping. The explosion of parts or uneven overflow of glue during the framing process is more obvious. Utility Model Content

[0004] The utility model provides a photovoltaic component, aiming to solve the problem of glue overflow on the front side when laminating parts and frames are bonded in the prior art.

[0005] The utility model is implemented in this way: a photovoltaic component comprises a lightweight flexible laminate and a frame arranged at the outer edge of the lightweight flexible laminate, wherein at least one vertex of the lightweight flexible laminate is rounded or chamfered.

[0006] Optionally, all top corners of the lightweight flexible laminate are rounded or chamfered.

[0007] Optionally, when a chamfer is provided at a top corner of the lightweight flexible laminate, the chamfer is a 45° chamfer.

[0008] Optionally, the chamfer size is 1 to 15 mm.

[0009] Optionally, when the top corners of the lightweight flexible laminate are rounded, the rounding radius is 0.5 to 10 mm.

[0010] Optionally, a glue overflow structure is provided on the frame.

[0011] Optionally, at least one shearing groove is provided on the outer edge of the lightweight flexible laminate.

[0013] Optionally, the shear groove is arranged at a central position of each edge of the lightweight flexible laminate.

[0014] Optionally, the shear groove has a groove depth of 1 to 5 mm.

[0015] The utility model has the beneficial effect that a frame is arranged at the outer edge of the lightweight flexible laminate, thereby providing a solid peripheral support structure for the lightweight flexible laminate. At least one vertex of the lightweight flexible laminate is rounded or chamfered, and when adhesive is used for bonding, the rounded or chamfered vertex forms a guide at the vertex position, thereby reducing the obstruction of the vertex to the adhesive, reducing the flow resistance of the colloid, and reducing the uneven pressure and adhesive overflow caused by the resistance of the vertex.

[0029] The utility model provides a frame on the outer edge of the lightweight flexible laminate, providing a solid peripheral support structure for the lightweight flexibility. At least one vertex of the lightweight flexible laminate is rounded or chamfered, and when adhesive is used for bonding, the rounded or chamfered vertex forms a guide, which reduces the obstruction of the vertex to the adhesive, reduces the flow resistance of the colloid, and reduces the uneven pressure and adhesive overflow caused by the resistance of the vertex.

[0030] Embodiment 1

[0031] like Figure 1 to Figure 2 As shown, this embodiment provides a photovoltaic module 100, including a lightweight flexible laminate 101 and a frame 102 framed on the outer edge of the lightweight flexible laminate 101, and at least one vertex of the lightweight flexible laminate 101 is rounded or chamfered.

[0032] The lightweight flexible laminate 101 is a laminate commonly used in the photovoltaic field. It is made of lightweight materials laminated together, has good overall structural flexibility, and is lighter in weight. It is widely used on roofs that cannot withstand heavy loads or on some portable equipment.

[0033] A frame 102 is arranged at the outer edge of the lightweight flexible laminate 101. The frame 102 can provide a solid peripheral support structure for the lightweight flexible laminate 101, and can maintain good structural integrity in some harsh usage environments, such as high wind speed and snow accumulation.

[0034] The lightweight flexible laminate 101 and the frame 102 are bonded together by adhesive, and at least one top corner of the lightweight flexible laminate 101 is rounded or chamfered. The rounding or chamfering forms a guide at the top corner position, which reduces the obstruction of the top corner to the adhesive, reduces the resistance to the flow of the colloid, and reduces the uneven pressure and abnormal glue overflow caused by the resistance at the top corner.

[0035] Embodiment 2

[0036] Based on the first embodiment, all the top corners of the lightweight flexible laminate 101 are rounded or chamfered.

[0037] like Figures 2 to 4 As shown, the lightweight flexible laminate 101 is square and has four corners, and rounding and chamfering are set at the four corners. Specifically, all four corners can be rounded, or all four corners can be chamfered, or some corners can be rounded and the remaining corners can be chamfered. All corners are rounded or chamfered to avoid the existence of sharp corners that hinder the flow of viscose.

[0038] It is understandable that the shapes of the lightweight flexible laminate 101 are different, and the number of vertex angles is different, and all vertex angles are rounded or chamfered. For example, if the lightweight flexible laminate 101 is a pentagon, five vertex angles are rounded or chamfered; if the lightweight flexible laminate 101 is a hexagon, six vertex angles are rounded or chamfered.

[0039] Embodiment 3

[0040] On the basis of the first embodiment, when the top corner of the lightweight flexible laminate 101 is chamfered, the chamfer is 45°.

[0041] In this embodiment, if Figure 2 As shown, the chamfer is set to 45 degrees, which helps to minimize the flow resistance of the colloid at the corner, ensures that the colloid flows more smoothly in the frame 102, and reduces the occurrence of glue overflow and other flow problems.

[0042] In one embodiment, the chamfer size is 1 to 15 mm, so as to avoid the situation that the frame 102 and the lightweight flexible laminate 101 cannot fit together due to excessive cutting.

[0043] Embodiment 4

[0044] On the basis of the first embodiment, when the top corners of the lightweight flexible laminate 101 are rounded, the rounding radius is 0.5 to 10 mm.

[0045] In this embodiment, if Figure 3 As shown, the rounded setting can disperse the force on the edge of the colloid, reduce the accumulation of the colloid at the edge, and thus reduce the possibility of glue overflow. The arc edge has no sharp edges and corners, and it is not easy to trap the colloid in the gaps or dead corners at the edge, avoiding the glue overflow caused by the inability of the colloid to flow, and the rounded shape allows the colloid to flow more smoothly at the edge of the frame 102, reducing the possibility of colloid flow being blocked, helping to control the flow direction and speed of the colloid, and reducing the risk of glue overflow.

[0046] The rounding radius is set to 0.5 to 10 mm to avoid excessive cutting that may cause the frame 102 and the lightweight flexible laminate 101 to fail to fit together.

[0047] Embodiment 5

[0048] On the basis of the first embodiment, a glue overflow structure is provided on the frame 102 .

[0049] A common glue overflow structure on the frame 102 is a glue overflow groove, which can be used to store excess glue, thereby reducing the risk of glue overflow.

[0050] Embodiment 6

[0051] On the basis of Example 1, Figure 5 As shown, at least one shearing groove is provided on the outer edge of the lightweight flexible laminate 101 .

[0052] The lightweight flexible laminate 101 is configured as a polygon, and an overflow shear groove is provided on at least one side, and the groove runs from the front side of the lightweight flexible laminate 101 to the back side of the lightweight flexible laminate 101. The provision of the shear groove can effectively reduce the tension of the edge, alleviate the warping tolerance of the lightweight component after lamination, and effectively solve the problems of warping explosion and uneven glue overflow on the long side during the framing process.

[0053] In one embodiment, the lightweight flexible laminate 101 is configured in a rectangular shape, and the shear grooves are respectively disposed on two opposite long sides to reduce the tension of the long sides.

[0054] In one embodiment, the groove depth of the shear groove is 1 to 5 mm, so as to avoid the situation where the frame 102 and the lightweight flexible laminate 101 cannot fit together due to excessive cutting.

[0055] In one embodiment, the shear groove is arranged at the center of each edge of the lightweight flexible laminate. The shear groove is arranged at the center position, has good symmetry, and the distance between the edge of the shear groove and the adjacent edge is consistent, which is conducive to ensuring the stability of the lightweight flexible laminate 101.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
