Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] see figure 1 Shown is a structural schematic diagram of the photovoltaic module in the photovoltaic module lamination process of the present invention. The photovoltaic module includes a glass plate 11, a TPT (not shown), an encapsulation film 12, a solar cell string 1, an encapsulation film 14, a TPT (not shown) and a glass plate 15 stacked sequentially from top to bottom. .

[0031] Such as figure 2 Shown is a conventional heating method for the lamination process of photovoltaic modules. In the traditional heating method, the laminator only has the heating plate 2 located below the photovoltaic module, and the photovoltaic module is heated mainly through the contact heat conduction of the heating plate 2 . The photovoltaic module is...

Abstract

The present invention provides a photovoltaic module lamination process, including the following process flow: ① providing a photovoltaic module and a laminator for laminating the photovoltaic module, the laminator is provided with a heating plate, and the photovoltaic module There is a self-heating plate on the top; ②Set the lamination parameters on the laminator, and when the temperature of the heating plate and the self-heating plate reaches the specified temperature, put the photovoltaic module into the laminator and close the cover; Vacuuming operation between the layers; ④Then pressurize the upper chamber of the laminator, press the self-heating plate to the top of the photovoltaic module, and the self-heating plate and the heating plate simultaneously The photovoltaic module is heated; ⑤ After lamination, the lower chamber of the laminator is inflated, the upper chamber is evacuated, the upper cover is opened, and the photovoltaic module is taken out, and the lamination is completed. Such setting effectively controls the heating temperature of the photovoltaic modules at different stages, shortens the lamination time of the photovoltaic modules, and improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic modules, in particular to a photovoltaic module lamination process that shortens the lamination time of photovoltaic modules and improves the lamination efficiency of photovoltaic modules. Background technique [0002] The lamination process of photovoltaic modules is an important part of the photovoltaic module manufacturing process. In the laminator, the air in the photovoltaic module is drawn out by vacuuming, and then heated to melt the encapsulation film to bond the solar cell strings, glass and backplane glass together. The main structure of the laminator is composed of upper and lower vacuum chambers, silica gel plates, heating systems, vacuum systems, heating control systems, control systems, etc. [0003] The lamination process adopted in the lamination process is to complete the exhaustion, heating, and curing in the lamination machine at one time. In the traditional photovo...
