Embodiment 1

[0023] Such as figure 1 and figure 2 As shown, the application provides a double-glass module lamination system, which includes a laminator heating plate 1, a laminator silica gel plate 2, wherein the double-glass battery assembly is arranged on the laminator heating plate 1 and the laminator Between the silica gel plates 2, the double-glass battery assembly includes the back glass 3 and the battery substrate 4, there is an encapsulation film 5 between the back glass 3 and the battery substrate 4, and butyl glue is coated on the edge of the encapsulation film 5 6. Since the silicone plate of the laminator is covered on the back glass, the edge of the back glass is prone to overvoltage abnormality, and the back glass is slightly deformed, resulting in a thin edge of the double-glass battery module. In the subsequent reliability test, it is easy to occur The shape of the glass on the back bounces back, causing abnormal water leakage at the edge of the component. In order to s...

Abstract

The invention discloses a double-glass component lamination system. The double-glass component lamination system comprises a lamination machine heating plate, a lamination machine silica gel plate anda double-glass battery component arranged between the lamination machine heating plate and the lamination machine silica gel plate, and is characterized in that a supporting system is arranged abovethe lamination machine heating plate; the supporting system is used for supporting the lamination machine silica gel plate; the supporting system comprises a top block and a driving mechanism; the driving mechanism is used for controlling the top block to ascend and descend; the top block comprises a top block crown part and a top block telescopic plate; the driving mechanism comprises an air cylinder, air cylinder brackets and an air cylinder piston rod; the air cylinder brackets are fixed at the two ends of the air cylinder; the air cylinder piston rod is fixed at the top end of the air cylinder and is used for connecting with the top block. The system avoids deformation caused by overpressure of the edge of the double-glass component and guarantees the quality and the performance of thedouble-glass component.

Description

technical field [0001] The invention relates to the field of solar cell components, in particular to a double-glass component lamination system. Background technique [0002] In recent years, the research directions of solar cells are high conversion efficiency, low cost and high stability. Therefore, thin-film solar cells represented by cadmium telluride thin-film solar cells have attracted much attention, and many organizations and companies have begun research and testing. Cadmium telluride thin-film solar cells are referred to as CdTe cells. It is a p-type CdTe and n Cd-type heterojunction-based thin-film solar cells, cadmium telluride thin-film solar cells are the easiest to manufacture in solar cells, so it is the fastest to commercialize. [0003] With the continuous development of cadmium telluride solar cells, double-glass modules gradually appear, but there are many problems in the manufacturing process of double-glass modules, which is also an important reason wh...
