Technical field

This application relates to the technical field of photovoltaic module production equipment, for example, to a frame taking device and a solar laminator.

Background technique

Solar laminators, often called laminators, are used in solar cell photovoltaic production lines. They usually combine layers of glass, ethylene-vinyl acetate copolymer (ethyl vinyl acetate, EVA), cells, EVA and backsheets. Pressing together to form a photovoltaic module, the principle of the solar laminator is to apply a certain pressure on the surface of each layer of material, and tightly press these materials together under heating. Since photovoltaic modules have a certain thickness, in order to ensure that the above-mentioned layers of materials are not laminated correctly during lamination, a lamination frame is usually configured, that is, glass, EVA, cells, EVA and backsheets are placed in the lamination frame for lamination. After the lamination is completed, the laminate frame and the solar photovoltaic module need to be separated.

In the related technology, the way to separate the photovoltaic module and the laminated frame is to use a pair of clamping cylinders to clamp the two opposite sides of the laminated frame, and then lift the laminated frame together to make the laminated frame and the inside of the laminated frame of photovoltaic modules separated. However, during lamination, the EVA glue in the photovoltaic modules will overflow, causing the laminate frame to adhere to the sides of the photovoltaic modules. As a result, the middle section of the laminate frame will be bent and damaged when the laminate frame is lifted.
