[0057] Example

[0058] See Figure 1 , Figure 2 This embodiment provides an encapsulation border 10, the length of which refers to... Figure 2 The length of the encapsulation frame 10 along the straight line L is 1134mm. It includes a frame body 100, a support plate 200, a mounting plate 300, and a support groove 400. The frame body 100 has a U-shaped structure, and the support plate 200 abuts against both end faces of the frame body 100, forming a cavity together with the frame body. One edge of the mounting plate 300 is connected to one outer wall of the frame body 100. The support groove 400 has an L-shaped structure, with one end face connected to one outer wall of the frame body 100. The end face of the support groove 400 is flat compared to the support plate 200. The distance between the outer wall of the frame body 100 away from the support plate 200 and the outer wall of the support groove 400 away from the frame body 100 is the thickness of the encapsulation frame, which is 30mm. A 0.1134mm diameter is provided on the side of the support plate 200 that contacts the photovoltaic panel 20. 2 A rectangular anti-slip structure 2001 is provided, which is composed of several wavy anti-slip patterns. An overflow groove 1001 with a depth of 0.6 mm is provided on one inner wall of the frame body 100, and the length of the overflow groove 1001 is the same as the length of the encapsulation frame 10. A reinforcing rib 1002 is provided on the lower surface of the support plate 200, and the same reinforcing rib 1002 is provided on one inner wall of the opposite frame body 100. The cavity area enclosed by the frame body 100 and the support plate 200 is used to fit corner brackets.

[0059] The photovoltaic panel 20 is installed within the area enclosed by the support plate 200 and the support groove 400, see reference. Figure 2 When the photovoltaic panel 20 is installed, the support plate 200 directly and partially supports the photovoltaic panel 20. The top surface of the support groove 400 is flush with the glass surface of the photovoltaic panel 20. The photovoltaic panel 20 is not embedded in the support groove 400. That is, when the photovoltaic panel 20 is encapsulated or assembled, it is not embedded in the encapsulation frame 10 provided in this embodiment, but is embedded in the long side frame.

[0060] In summary, the aforementioned encapsulation frame 10 ensures that the frame and the module glass surface are at the same height, allowing rainwater to flow smoothly down the frame naturally, effectively reducing dust accumulation on the front of the module and minimizing dust buildup. The addition of an anti-slip structure further stabilizes the module, and the inclusion of an anti-overflow adhesive structure effectively traps excess adhesive, reducing spillage. This improves production efficiency, reduces costs, and enhances product quality.

[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
