The conventional laminated frame is generally a rectangular metal frame, with a thickness similar to that of the double-glass photovoltaic panel assembly. The internal space of the laminated frame can accommodate the double-glass photovoltaic panel assembly. The front surface of the laminated frame is generally fixed with several flexible pull tapes, which span the internal space and are used to limit the upper surface of the double-glass photovoltaic panel assembly, ensuring that the double-glass photovoltaic panel assembly will not slide out of the internal space of the laminated frame due to vibration. The outer surface of the laminated frame is generally wrapped with a Teflon fiberglass tape, which has good lubricating and anti-adhesion effects, and can prevent the adhesive on the double-glass photovoltaic panel assembly from being adhered and fixed to the laminated frame during the laminating process.
