Description

Technical Field

[0001] The present disclosure relates to the technical field of photovoltaic module production, and in particular to an EVA cutting machine. Background Art

[0002] Ethylene-vinyl acetate copolymer (EVA) is an important packaging material in the photovoltaic cell industry due to its advantages in adhesion, light transmittance and durability. During the production of photovoltaic cell modules, the film needs to be cut into the required size first, and then the EVA film is attached to the surface of the cell to reduce the impact of the external environment on the electrical properties of the cell. It can also prevent the cell from cracking during the transportation and installation of photovoltaic modules.

[0003] Because the quality of EVA affects the lifespan of solar panels, EVA coils are randomly inspected before processing begins. Only those that pass the inspection can be put into production. However, incoming EVA coils are typically wound on transport rollers, making the center section difficult to inspect. This section may contain cosmetic defects such as voids, spots, and bubbles. To avoid affecting the final product quality, a second random inspection process is typically performed after the EVA is cut to identify defective EVA products. This increases the burden on production line workers and affects overall processing efficiency. Utility Model Content

During this movement, multiple inspection cameras 42 on the sliding base 41 photograph the EVA and inspect its appearance. After the inspection is complete, the inspection drive 43 drives the sliding base 41 to reset, and the cutter 33 moves upward to cut the EVA. The cutting jaws 32 grip the cut EVA and move it toward the conveyor line. If the inspection result is a good product, the moving seat 34 drives the cutting jaws 32 to move to the conveyor line position, directly placing the EVA on the conveyor line and transporting it out from the conveyor line. If it is a defective product, when passing the collection box 36 position, the cutting jaws 32 move down and place the EVA into the collection box 36.

[0083] The cutting machine provided by the present invention fully inspects the EVA coil online and removes defective parts while performing the cutting operation, eliminating the need for adding a manual inspection process after the cutting operation. This not only ensures the quality of the EVA coil and increases the life of the solar cell panel, but also reduces production costs and improves production efficiency.
