Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel production, and particularly to a photovoltaic panel production device. Background Art

[0002] Solar photovoltaic glass is a special glass that can generate electricity by laminating solar cells into it, utilizing solar radiation, and having relevant current lead-out devices and cables. It is composed of low-iron glass, solar photovoltaic panels, films, back glass, and special metal wires. The solar photovoltaic panels are sealed between a piece of low-iron glass and a piece of back glass through a film, and it is a novel high-tech glass product for construction.

[0003] During the production process, string welding and lamination are two independent processes, which are carried out at different workstations during pressing. The string welding workstation is mainly responsible for connecting the qualified photovoltaic panels in series according to a certain rule to form a battery string, while the lamination workstation is to put the stacked photovoltaic modules into a laminator for high-temperature and high-pressure treatment, and an integrated effect cannot be achieved. On the other hand, during string welding, a specified number of already welded photovoltaic panels are arranged face down on the template. One hand gently presses two photovoltaic panels to make them stick tightly to the heating template, and then the solder strip led out from the latter photovoltaic panel is pressure-welded to the back electrode of the previous photovoltaic panel according to the specified spacing (usually 2 ± 0.5 mm). Most of them are manual operations, and the degree of mechanization is low. Moreover, due to the small contact area between the photovoltaic panel and the contact plate, the photovoltaic panel is prone to breakage and damage under high pressure at this time. At the same time, during pressing, due to mechanical extrusion, it is inconvenient to adjust the pressure between the pressing plate and the photovoltaic panel. Therefore, when the pressure between the pressing plate and the photovoltaic panel is too large, it is easy to cause damage to the photovoltaic panel or the pressing plate. When the photovoltaic panel is unevenly stressed, the layers are prone to shift, resulting in delamination of the photovoltaic panel. Summary of the Invention
