Photovoltaic module lamination device and lamination method

Abstract

The present invention discloses a photovoltaic assembly lamination apparatus and a photovoltaic assembly lamination method. The photovoltaic assembly lamination apparatus comprises a shaping mold for being fixed on the peripheral edge of a photovoltaic assembly, wherein the shaping mold is provided with shaping arms and shaping grooves positioned between the shaping arms and the peripheral edge of the photovoltaic assembly, the shaping grooves are surrounding the periphery of the photovoltaic assembly and are continuously distributed, and are used for accommodating the encapsulation glue film overflowing from the photovoltaic assembly. According to the present invention, the shaping mold is arranged on the peripheral edge of the photovoltaic assembly before the lamination, such that the encapsulation glue film overflowing from the photovoltaic assembly can directly enter the shaping mold and is shaped during the lamination process, and finally the glue strip around the peripheral edge of the photovoltaic assembly is formed and has characteristics of unified and regular shape and excellent beauty so as not to require the edge cutting treatment of the photovoltaic assembly after the lamination and so as to save the process and the cost and improve the impact resistance of the photovoltaic assembly.

Description

technical field [0001] The invention relates to a photovoltaic module manufacturing technology, in particular to a photovoltaic module lamination device and a lamination method. Background technique [0002] The photovoltaic module is composed of a transparent cover plate, a back plate, an encapsulation film sandwiched between the back plate and the transparent cover plate, and photovoltaic cells. The above components form a complete photovoltaic module or photovoltaic panel through a lamination process. During the lamination process, The cover plate and the back plate will be subject to enormous pressure, making the encapsulation film between them easy to overflow from the surroundings, especially for double-glass photovoltaic modules. Since the transparent cover plate and back plate are made of glass, and the double-glass photovoltaic modules The frameless design is often adopted. Therefore, once the encapsulation film overflows from the surrounding edges of the double-gla...

[0002] The photovoltaic module is composed of a transparent cover plate, a back plate, an encapsulation film sandwiched between the back plate and the transparent cover plate, and photovoltaic cells. The above components form a complete photovoltaic module or photovoltaic panel through a lamination process. During the lamination process, The cover plate and the back plate will be subject to enormous pressure, making the encapsulation film between them easy to overflow from the surroundings, especially for double-glass photovoltaic modules. Since the transparent cover plate and back plate are made of glass, and the double-glass photovoltaic modules The frameless design is often adopted. Therefore, once the encapsulation film overflows from the surrounding edges of the double-glass photovoltaic module, it is very easy to cross-contaminate the cover glass and the back glass. The extra film on the edge of the module will increase the workload after lamination, and the quality of trimming will directly affect the aesthetics of the double-glass photovoltaic module. If the double-glass photovoltaic module is impacted after trimming, the cover glass and the back The plate glass will be directly stressed, and there is a greater risk of shattering
