The flipping device 42 in the storage mechanism 4 flips the products 90° from a lying state to a standing state and stores them in an orderly manner. Finally, the neatly arranged and stored products are transferred from the storage mechanism 4 to the outside through the output device 5 to complete the unloading. This effectively saves indoor space, reduces the manpower input in grading photovoltaic modules, improves the production efficiency of photovoltaic module products, and realizes the automated and intelligent production of photovoltaic modules.
