Manufacturing process of photovoltaic module

Abstract

The invention relates to a manufacturing process of a photovoltaic module. The manufacturing process comprises the following technological processes including a welding work procedure, a lamination work procedure, a lamination pressing work procedure, a framing work procedure and a module turnover work procedure. Each flow process is innovated, and a specific and bran-new module manufacturing process is formed. The manufacturing process has the beneficial effects that the work efficiency is high, fragments caused by to great temperature differences during welding can be effectively reduced, and the service life of the module is prolonged. The silica gel loss is reduced, the labor is saved, and the cost is reduced. During the framing, a strict automatic glue overflowing module is adopted, and the environment requirements such as the sealing performance of the module and the high pressure resistance of the module can be ensured. The defects such as silica gel filling gaps inside the module and flue leakage, influencing the module performance, during secondary glue filling of manual glue filling are avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic solar energy, in particular to a manufacturing process of a photovoltaic module. Background technique [0002] Photovoltaic modules can convert light energy into electrical energy, and the cells packaged in photovoltaic modules are the photoelectric conversion units of photovoltaic modules. In the traditional manufacturing process, the battery fragment rate is high, which is not conducive to cost control. The low transmittance of EVA on the glass surface affects the power of the module, and the high transmittance of EVA on the backplane affects the life of the module. The production of conventional laminated formwork is cumbersome and expensive, and the research and development of simple and low-cost laminated formwork is an urgent problem to be solved. The lamination process uses a single-cavity laminator, and the production efficiency cannot meet the increasing production capacity needs. ...

The production of conventional laminated templates is cumbersome and expensive, and the research and development of laminated templates is an urgent problem to be solved.

The lamination process uses a single-cavity laminator, and the production efficiency cannot meet the increasing production capacity needs

Complicated operation and low production efficiency

The panel of the conventional module turnover tray is flat. If the module is placed with the back panel facing down, the upper and lower modules are easy to slide, and there is a risk of explosion, and it is difficult for the operator to handle a single module. If the module is placed with the glass side down When using a forklift to lift the entire pallet assembly, the pallet will be deformed from the position of the fork arm of the forklift, and the glass surface of the component that is close to the pallet will be forced to cause cracks
