[0019] The present invention will be further described with reference to the accompanying drawings.

[0020] Embodiment 1

[0021] like Figures 1 to 4 As shown, a solar cell assembly frame includes a frame 1 body, the frame 1 is a profile, the two ends of the frame 1 are inclined surfaces, the angle of the inclined surfaces is 45 degrees, the frame 1 body is provided with a slot 11 for fixing the solar cell panel, a fixing hole 12 for installing the angle code 2 and a connecting plate 13, the slot 11 and the connecting plate 13 are respectively located at the top and bottom of the fixing hole 12; the slot 11 is provided with a top wall 111, a side wall 112 and a bottom wall 113, the top wall 111 is parallel to the bottom wall 113, and the side wall 112 is perpendicular to the top wall 111 and the bottom wall 113; the top wall 111 is provided with a glue overflow groove 114, the bottom of the glue overflow groove 114 is arc-shaped, the two sides of the glue overflow groove 114 are inclined toward the bottom of the glue overflow groove 114, and the glue overflow groove 114 has a small mouth and a large interior.

[0022] Specifically, the frame 1 is an aluminum profile, and the inclined surfaces at both ends of the frame 1 are used to splice into a rectangular frame, and the corner brackets 2 are inserted into the fixing holes 12, and the corner brackets 2 fix the four frames 1. The top wall 111 is parallel to the bottom wall 113, and the side wall 112 is perpendicular to the top wall 111 and the bottom wall 113, which is convenient for mold making of the frame 1, and at the same time reduces the gap between the card slot 11 and the solar cell panel, and reduces the amount of silicone.

[0023] When applying glue, evenly apply the silicone along the side wall 112 of the slot 11, and then insert the solar panel. The silicone is squeezed and flows toward the top wall 111 and the bottom wall 113 of the slot 11. The silicone flowing to the top wall 111 will enter the overflow glue groove 114. The side of the overflow glue groove 114 away from the side wall 112 guides the silicone to flow into the overflow glue groove 114 to prevent the silicone from overflowing to the front of the solar panel. The arc-shaped bottom of the overflow glue groove 114 increases the volume, which can accommodate more silicone and reduce the overflow of silicone. The inclined surface of the overflow glue groove 114 on the side of the side wall 112 can increase the volume of the overflow glue groove 114. The silicone overflowing from the bottom wall 113 forms a good seal between the solar panel and the aluminum profile.

[0024] like Figure 2 As shown, the width ratio of the side wall 112 to the top wall 111 is 1:1 to 1:1.4. The width ratio of the top wall 111 to the side wall 112 of the existing profile reaches 1:2 or more, that is, the width of the top wall 111 is large. The large width of the top wall 111 causes the cross-sectional area of ​​the profile to be large, the weight of the frame 1 becomes large, and the cost of the frame 1 is high. At the same time, the large width of the top wall 111 means that the depth of the card slot 11 is deep. The deep depth of the card slot 11 requires more silica gel to fill, and the price of silica gel is also expensive, resulting in a high overall cost. The amount of silica gel used is reduced by reducing the width of the top wall 111 and the bottom wall 113. In production, the amount of silica gel used in a solar panel assembly is reduced from 225g to 185g, which effectively reduces the amount of silica gel used and reduces costs. Reducing the top wall 111 and the bottom wall 113 can also reduce the weight of the frame 1, further reducing material costs and the weight of solar modules.

[0025] Further, such as Figure 1 and Figure 4 As shown, the frame 1 is also provided with a water outlet 15, which is communicated with the fixing hole 12. The water outlet 15 is located on the bottom surface of the fixing hole 12. A baffle 16 is provided on the water outlet 15, and the baffle 16 is inclined and located inside the fixing hole 12. The water outlet 15 prevents rainwater from gathering in the fixing hole 12 and corroding the aluminum profile. Discharging rainwater in time can also prevent rainwater from increasing the weight of the solar panel assembly and reduce the impact on the mounting bracket. The water outlet 15 is located on the bottom surface of the frame 1, and the baffle 16 can effectively prevent debris from entering the fixing hole 12.

[0026] The water outlet hole 15 is formed by stamping without waste material. The blanking material of the water outlet hole 15 forms a baffle 16. The baffle 16 is stamped into the interior of the fixing hole 12 and has a certain angle to block external debris from entering.

[0027] like Figure 1 As shown, a plurality of waist-shaped holes 14 are provided on the connecting plate 13. The waist-shaped holes 14 are used to fix the solar panel assembly and the bracket.

[0028] like Figure 1 and Figure 4 As shown, the frame 1 body is provided with a check hole 17, which is an isosceles right triangle, and is located on the inclined planes at both ends of the frame 1 and on the connecting plate 13. When the frame 1 is spliced ​​into a frame, two adjacent check holes 17 form a complete square. If two adjacent check holes 17 cannot form a complete square, that is, two adjacent check holes 17 are staggered, it means that the frame 1 is installed skewed, so that rapid inspection can be achieved and production efficiency can be improved.

[0029] Embodiment 2

[0030] Based on the above embodiments, Figure 2 and Figure 5 As shown, a rib 115 is further disposed at the end of the top wall 111 . The rib 115 is arc-shaped and higher than the top wall 111 .

[0031] When the solar panel is inserted into the slot 11, since the retaining edge 115 is higher than the top wall 111, the retaining edge 115 pushes the top wall 111 to deform, and the deformed part is located in the overflow glue groove 114, so that the top of the inclined surface of the overflow glue groove 114 close to the retaining edge 115 is pressed onto the solar panel, forming two barriers, which fully ensures that the silica gel will not overflow to the front of the solar panel, thereby reducing the process and improving the production efficiency.
