Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic equipment manufacturing, and in particular to a photovoltaic panel molding device and a molding method for photovoltaic equipment manufacturing. Background Art

[0002] Solar energy is a new type of green renewable energy. Solar photovoltaic cells use the photovoltaic effect to complete photoelectric conversion. In recent years, domestic photovoltaic power stations have shown explosive growth. Photovoltaic power stations occupy more and more land resources, and the demand for photovoltaic panels has continued to rise. Photovoltaic panels, also known as solar panels, are one of the core parts of photovoltaic power generation systems. Photovoltaic panels are mainly composed of tempered glass, EVA, cells, backboards and frames. During the production process, the various layers of photovoltaic components (such as glass, cells, EVA and backboards) need to be fixed and sealed by molding to ensure the structural stability and long-lasting performance of photovoltaic components.

[0003] Reference patent application number CN202410383864.X is a photovoltaic panel molding device for photovoltaic equipment manufacturing. The prior art performs molding work by means of a hot pressing plate.
