Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component product production, in particular to a photovoltaic component lamination auxiliary tooling. Background Art

[0002] When solar photovoltaic double-glass modules are laminated, snowflake-shaped bubbles are prone to appear at the four corners of the modules and bubbles around the edges. Compared with the back panel, the back glass is thicker and more rigid. During the lamination and vacuuming process, the laminating silicone plate is pressed tightly on the four sides of the glass. The edge of the upper glass is subjected to greater force than other parts, resulting in uneven force on the upper glass and deformation. The edge glass deforms downward, causing the air inside the EVA to not be removed in time and gather at the edge of the upper glass, forming residual bubbles.

[0003] During the opening process, since the EVA has not been completely solidified, the elasticity of the glass itself will cause the glass on all sides to recover, and the glass rebounds to gradually precipitate vacuum bubbles on all sides. For the bubbles that appear in the double glass, the existing solution is to use auxiliary frames to make the force on all sides uniform to prevent the four corners from sucking back and generating bubbles. The auxiliary frames are expensive and difficult to place. The existing corner protectors have high requirements for employees and have a high risk of explosion. In order to improve production efficiency, reduce costs and the risk of explosion, there is an urgent need for a lamination auxiliary tooling that is easy to install, low cost, and has a low risk of explosion.

[0007] The adhesive containing groove is arranged between the gap formed by the side plate and the reinforcing rib and between the side plate and the back glass assembly;

[0008] A top plate is arranged on top of the two side plates.

[0009] Furthermore, the two side panels are stacked and installed by bolts to form an "L"-shaped structure, the thickness of the side panel is 8 mm, and the length of the side panel is 50 mm.

[0010] Furthermore, the back glass assembly is a rectangular structure, and the two side panels are respectively parallel to the edges of the back glass assembly.

[0011] Furthermore, two reinforcing ribs are fixedly connected to the two side panels respectively, and the spacing between the two reinforcing ribs located on the same side panel is 25 mm.
