[0002] With technological advancements, the photovoltaic industry has experienced rapid growth, and photovoltaic products have been applied in numerous fields. Photovoltaic modules (also known as solar cell modules) are power generation devices that convert light energy into electricity. Their efficiency, quality, safety, cost, and service life are crucial indicators. The manufacturing equipment used to manufacture these modules plays a crucial role in determining their efficiency, quality, safety, cost, and service life.

[0003] The frame of a solar photovoltaic module is an important component of a solar photovoltaic module. It is encapsulated on the side of the photovoltaic panel to seal the photovoltaic panel, ensure that the photovoltaic module has good mechanical properties, and facilitate quick installation in different usage environments. The frame of a solar photovoltaic module is generally an aluminum alloy frame. The aluminum alloy frame is provided with a cavity for connecting to the photovoltaic panel. The cross-section of the cavity is usually star-U-shaped. The edge of the photovoltaic panel is inserted into the cavity of the aluminum alloy frame to achieve connection. The aluminum frame of the photovoltaic module needs to be stamped during the production and processing process. Although the aluminum frame stamping equipment of the photovoltaic module in the prior art can realize the automatic stamping task, it cannot flexibly remove the formed product.
