Technical Field
[0001] The utility model relates to the technical field of photovoltaic component production, in particular to a photovoltaic component edge trimming device. Background Art
[0002] Photovoltaic modules, also known as solar panels, can convert solar energy into electrical energy. They are composed of photovoltaic glass, EVA film, battery cells, EVA film, backplane, frame, junction box and other components laid from top to bottom. During production and processing, the first layer of EVA film needs to be laid on the photovoltaic glass first. The battery cells are diced, welded, laid out, and stacked to form a whole battery panel laid on the first layer of EVA film. After fixing it with tape, the second layer of EVA film and backplane are laid. Then, they need to be heated through a lamination process to melt the EVA film and tape and bond them together. However, the EVA film and tape will overflow from the edge of the module when they melt, which requires the edge of the module to be trimmed.
[0003] At present, photovoltaic edge trimming machines are generally used to trim the edges of photovoltaic modules. Figure 1 As shown, it is mainly composed of a lifting conveyor belt 1, a limiting roller 2 in the front, straightening rollers 3 on both sides, and a cutting mechanism 4 around. The limiting roller 2 in the front and the straightening rollers 3 on both sides are located in a higher layer, and the cutting mechanism 4 around is located in a lower layer. After the laminated photovoltaic module 5 is fed into the lifting conveyor belt 1, the front frame of the photovoltaic module 5 is first blocked by the limiting roller 2, and then the straightening rollers 3 on both sides are synchronously gathered to the middle to clamp the photovoltaic module 5. Then the lifting conveyor belt 1 is lowered to the lowest position, and the cutting mechanisms 4 around are extended, and each passes along the edges of the photovoltaic module 5 to cut off the overflowed colloid. However, since the photovoltaic module 5 is placed on the lifting conveyor belt 1, the colloid overflowed from some photovoltaic modules 5 is thicker. When the cutting mechanism 4 scrapes from this position, it is easy to deviate the photovoltaic module 5, affecting the trimming effect.
