[0033] In the description of the present invention, "first feature" and "second feature" may include one or more such features, "plurality" means two or more, the first feature "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features not being in direct contact but being in contact through another feature between them, the first feature "above", "above" and "above" the second feature include the first feature being directly above and diagonally above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0034] During their use, photovoltaic modules are exposed to outdoor environments for a long time and are attacked by natural factors such as rain, dust, and wind and sand, which can easily cause damage to the internal circuits and components of the modules, affecting their power generation efficiency and service life.

[0035] like Figure 1 As shown, the photovoltaic module includes a double-glass module 200, which includes two glass layers 210, electronic components disposed between the two glass layers 210, and an adhesive layer 220 filling the gap between the two glass layers 210. The adhesive layer 220 may be, but is not limited to, butyl adhesive. During the production process, the double-glass module 200 undergoes a lamination process to solidify the adhesive layer 220 and expel the gas between the two glass layers 210.

[0036] In order to protect the internal structure of photovoltaic modules and enable them to operate stably for a long time, edge sealing structures must be used during the production process to effectively seal and reinforce the double-glass modules.

[0037] In the prior art, the edge sealing structure is completely bonded to the surface of the double-glass module, using a linear edge sealing method. This method can easily lead to excessive adhesive overflow during construction. Furthermore, the edge sealing structure in the prior art is large, which affects the stress of the double-glass module during the lamination process, resulting in poor lamination quality, low adhesive cross-linking, prone to bubbles, and easy delamination during use.

[0038] Based on this, the present application proposes an edge sealing structure 100, which has better edge sealing tightness and reliability for the double-glass component 200, the glue layer 220 is not easy to overflow excessively, and the lamination effect is better, and delamination is not easy to occur during use.

[0039] The edge sealing structure 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] Reference Figure 1-Figure 4 As shown, the edge sealing structure 100 according to an embodiment of the present invention includes an edge sealing tape 10. One side of the edge sealing tape 10 in the thickness direction has two connection areas 11 and a glue overflow groove 12. The two connection areas 11 are spaced apart along the width direction F1 of the edge sealing tape 10. The connection areas 11 are used to connect to the double-glass component 200. The glue overflow groove 12 is located between the two connection areas 11 and is used to accommodate glue overflow from the double-glass component 200. The edge sealing tape 10 is provided with a vent 13, which connects the glue overflow groove 12 to the outside. The thickness of the edge sealing tape 10 is 0.05mm to 0.1mm.

[0041] The connection area 11 and the double-glass assembly 200 can be connected by adhesive or other methods to achieve sealing. Here, the adhesive can be an adhesive film pre-set on the surface of the edge-sealing tape 10, or it can be glue applied to the surface of the edge-sealing tape 10 during the production process, etc.

[0042] The overflow glue groove 12 can be a groove formed by a depression on the surface of the edge-sealing tape 10, or can be a groove defined by the overall bending of the edge-sealing tape 10. It is only necessary that after the edge-sealing structure 100 is connected to the double-glass component 200 and before the lamination process, at least part of the groove wall of the overflow glue groove 12 is separated from the surface of the double-glass component 200 so that the space in the overflow glue groove 12 can accommodate the overflow glue during the lamination process.

[0043] The overflowing adhesive groove 12 is provided to contain the overflowing adhesive layer 220, preventing the adhesive layer 220 from overflowing excessively. Furthermore, the edge-sealing tape 10 can regulate the edge shape of the laminated adhesive layer 220, ensuring a neat and beautiful edge seal. This also reduces material waste, improves construction efficiency and quality, effectively protects the edges of the double-glass module 200, and enhances overall durability and waterproof performance. This enhances support and protection for the edges of the double-glass module 200, making it less susceptible to damage during transportation, installation, and use.

[0044] The exhaust hole 13 can be used to discharge the gas in the double-glass component 200. For example, during the lamination process, the gas can be discharged smoothly through the exhaust hole 13, ensuring the vacuum effect of the edge sealing, which is beneficial to improving the tightness and reliability of the edge sealing, and improving the performance and life of the photovoltaic component.

[0045] Furthermore, compared to edge sealing methods in related arts, the edge sealing tape 10 of the present application is thinner. During the lamination process, the edge sealing tape 10 interferes less with the double-glass module 200, and the lamination pressure is more evenly applied to the double-glass module 200. This results in a higher degree of cross-linking in the adhesive layer 220 of the double-glass module 200 after lamination, making it less prone to bubbles and thus reducing the risk of delamination during use. Furthermore, if the thickness of the edge sealing tape 10 is too small, the risk of the edge sealing tape 10 breaking is too high.

[0046] For example, in some embodiments, the thickness H of the edge-sealing tape 10 is between 0.05 mm and 0.1 mm. In some specific embodiments, the thickness of the edge-sealing tape 10 can be 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, etc.

[0047] According to the edge sealing structure 100 of the embodiment of the present invention, the double-glass component 200 is sealed by the edge sealing tape 10 with the exhaust hole 13, and the edge sealing tape 10 has a glue overflow groove 12 for accommodating glue overflow, so that the edge sealing structure 100 has better tightness and reliability in sealing the double-glass component 200, the glue layer 220 is not easy to overflow excessively, the lamination effect is better, and delamination is not easy to occur during use.

[0048] In some embodiments, as Figure 1 As shown, the thickness of the edge-sealing tape 10 is uniform everywhere, which makes the edge-sealing tape 10 easier to form, reduces the volume and material cost of the edge-sealing tape 10, and further reduces the impact of the edge-sealing tape 10 on the lamination during the lamination process.

[0049] In some embodiments, as Figure 1 As shown, the glue overflow groove 12 extends along the length direction F2 of the edge sealing tape 10. After the edge sealing tape 10 is arranged along the circumference of the double-glass assembly 200 and connected to the double-glass assembly 200, the glue overflow groove 12 can extend along the circumference of the double-glass assembly 200, that is, along the length direction of the gap between the edges of the two glass layers 210.

[0050] The cross section of the overflow groove 12 is C-shaped in a direction perpendicular to the length direction F2 of the edge-sealing tape 10. In a specific embodiment where the thickness of the edge-sealing tape 10 is uniform, the edge-sealing tape 10 is formed into a C-shaped structure as a whole.

[0051] As a result, the space in the overflow groove 12 is more reasonable, the edge sealing tape 10 is easier to shape, and the space utilization rate of the overflow groove 12 is higher, making it less likely for the overflow glue in the overflow groove 12 to overflow from the exhaust hole 13, making it less likely for burrs to form on the double-glass component 200.

[0052] In some embodiments, the edge-sealing tape 10 is made of a flexible material, such as PET. The flexible material can deform to a certain extent, which not only makes it easier for the edge-sealing tape 10 to be tightly connected to the double-glass module 200, but also helps reduce the interference of the force on the double-glass module 200 during the lamination process.

[0053] In some embodiments, the edge-sealing tape 10 is made of a transparent material. Here, the transparent material can be translucent or fully transparent, and can be colorless and transparent or colored and transparent.

[0054] The transparent material allows the structure of the double-glass component 200 (such as the structure at the edge) to be visible through the edge-sealing tape 10 after the edge-sealing tape 10 is connected to the double-glass component 200, thereby facilitating observation and inspection to determine whether there are any defects, burrs, etc.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2As shown, there are multiple exhaust holes 13, and multiple exhaust holes 13 can increase the total exhaust area to make exhaust smoother, thereby improving the vacuuming efficiency and the vacuum effect of edge sealing.

[0056] In some embodiments, at least two vent holes 13 are spaced apart along the length direction F2 of the edge-sealing tape 10 . In some embodiments, at least two vent holes 13 are spaced apart along the width direction F1 of the edge-sealing tape 10 .

[0057] In the present application, the length direction F2 of the edge-sealing tape 10 refers to the direction extending along the length direction of the edge of the double-glass assembly 200 when the edge-sealing tape 10 is connected to the double-glass assembly 200; the width direction F1 of the edge-sealing tape 10 refers to the direction from the outer surface of the glass layer 210 on one side of the double-glass assembly 200 to the outer surface of the glass layer 210 on the other side, that is, the direction in which the two connecting areas 11 are arranged apart.

[0058] By arranging the exhaust holes 13 at intervals along the length direction F2 of the edge-sealing tape 10, the multiple exhaust holes 13 can exhaust gas from different positions along the length direction of the edge of the double-glass assembly 200. This allows gas in different areas of the double-glass assembly 200 to be discharged through the exhaust holes 13 in the corresponding areas, and prevents the overflow of glue from filling the overflow groove 12 and affecting the gas discharge.

[0059] The exhaust holes 13 are spaced apart in the width direction F1 of the edge sealing tape 10 , so that the exhaust holes 13 can exhaust gas from different positions in the thickness direction of the edge of the double-glass assembly 200 , so that gas in different areas can be discharged smoothly.

[0060] In some embodiments, the plurality of exhaust holes 13 may be spaced apart in both the width direction F1 and the length direction F2. For example, in some specific embodiments, the plurality of exhaust holes 13 are arranged into a plurality of rows of hole groups 14 along the length direction F2 of the edge sealing tape 10. Each row of hole groups 14 includes a plurality of exhaust holes 13 arranged along the width direction F1 of the edge sealing tape 10. The arrangement of the plurality of exhaust holes 13 is more neat and orderly, which can not only further improve the exhaust smoothness, but also improve the exhaust uniformity and exhaust effect of the entire double-glass assembly 200.

[0061] In some embodiments, as Figure 2 As shown, the spacing L between two adjacent rows of hole groups 14 is 70 mm to 80 mm. If the spacing between two adjacent rows of hole groups 14 is too large, it will make it difficult for the gas between the two rows of hole groups 14 to be discharged. If the spacing between two adjacent rows of hole groups 14 is too small, the risk of the edge sealing tape 10 breaking and the risk of glue overflowing through the vent holes 13 will increase.

[0062] Within the above value range, the gas in different areas of the adhesive layer 220 can be discharged smoothly, and the edge sealing tape 10 has a stable structure and is not easy to break, and the overflowing glue is not easy to overflow through the exhaust hole 13.

[0063] It should be noted that the plurality of hole groups 14 may be distributed at equal intervals or at unequal intervals; the plurality of exhaust holes 13 in the same hole group 14 may be distributed at equal intervals or at unequal intervals.

[0064] In some embodiments, the diameter D of the vent hole 13 is between 0.5 mm and 1.5 mm. If the diameter of the vent hole 13 is too large, the risk of breakage of the edge-sealing tape 10 increases, and excess glue in the overflow groove 12 is easily discharged through the vent hole 13. If the diameter of the vent hole 13 is too small, the exhaust efficiency is low. Within the above range, the vent hole 13 can be vented smoothly, the edge-sealing tape 10 is less likely to break, and excess glue is less likely to escape through the vent hole 13, thereby improving the regularity of the edge sealing.

[0065] In some specific embodiments, the diameter of the exhaust hole 13 can be 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, 1.2 mm, 1.5 mm, etc.

[0066] It should be noted that the exhaust hole 13 can be any shape, such as a circular hole or a square hole. For a circular hole, the aperture of the exhaust hole 13 refers to the diameter of the circle; for a non-circular hole, the aperture of the exhaust hole 13 refers to the diameter of the circle that is equal to the flow area of ​​the exhaust hole 13.

[0067] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, the edge sealing structure 100 further includes a profile 20 , which has a cavity 21 , and the surface of the edge sealing tape 10 on the other side in the thickness direction is detachably attached to the inner wall surface of the cavity 21 .

[0068] The structure of the profile 20 is stable. The profile 20 can limit the shape of the edge-sealing tape 10, providing sufficient support and protection for the edge-sealing tape 10, so that the edge-sealing tape 10 is not easily deformed when sealing the double-glass component 200, thereby improving the connection reliability and sealing performance of the edge-sealing tape 10 and the double-glass component 200.

[0069] In addition, the edge-banding tape 10 is detachably attached to the inner wall surface of the cavity 21, so that during the edge-banding process, the profile 20 can be used to shape the edge-banding tape 10 to improve the edge-banding effect. During the lamination process, the profile 20 can be separated from the edge-banding tape 10 according to actual needs, so that the profile 20 is less likely to have an adverse effect on the lamination process.

[0070] It should be noted that the edge-sealing tape 10 can be a thin film strip structure, and the shape of the inner wall surface of the cavity 21 is restricted to deform the edge-sealing tape 10 to form the overflow groove 12; or, the edge-sealing tape 10 has the overflow groove 12 before it is matched with the profile 20, and the structure of the overflow groove 12 can be made more stable by matching with the profile 20.

[0071] In some embodiments, the profile 20 is made of metal, such as steel, etc. The metal profile 20 has high hardness and can provide more stable support for the edge sealing tape 10, thereby improving the edge sealing effect of the double-glass component 200.

[0072] The edge sealing machine according to the embodiment of the present invention includes the edge sealing structure 100 according to the embodiment of the present invention. Since the edge sealing structure 100 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the edge sealing machine according to the embodiment of the present invention uses the edge sealing tape 10 with the vent holes 13 to seal the double-glass component 200. The edge sealing tape 10 has an overflow groove 12 for accommodating overflow glue. This allows the edge sealing structure 100 to seal the double-glass component 200 with improved tightness and reliability, prevents excessive overflow of the glue layer 220, and achieves a better lamination effect, making delamination less likely to occur during use.

[0073] In some embodiments including the profile 20, the profile 20 may be a part of the edge banding machine body, or the profile 20 may be a separate part that can be matched with the edge banding machine body.

[0074] The laminating machine according to the embodiment of the present invention includes the edge sealing structure 100 according to the embodiment of the present invention. Because the edge sealing structure 100 according to the embodiment of the present invention has the aforementioned beneficial technical effects, the laminating machine according to the embodiment of the present invention uses the edge sealing tape 10 with vent holes 13 to seal the double-glass component 200. Furthermore, the edge sealing tape 10 has an overflow groove 12 for accommodating overflow glue. This allows the edge sealing structure 100 to provide improved tightness and reliability in sealing the double-glass component 200, prevents excessive overflow of the glue layer 220, and achieves a better lamination effect, making delamination less likely to occur during use.

[0075] In some embodiments including the profile 20, the profile 20 may be a part of the laminator body, or the profile 20 may be a separate part that can be matched with the laminator body.

[0076] Other structures and operations of the edge banding machine and the laminating machine according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
