Abstract

A recycle apparatus includes a conveyor, a flattening device, and a cutting tool. The conveyor includes a first roller and a second roller opposite to each other. The flattening device is located aside the first roller and the second roller. The cutting tool is located aside the flattening device. The flattening device is located between the first roller and the second roller of the conveyor and the cutting tool. The first roller and the second roller is configured to press and feed the photovoltaic module to the flattening device for allowing the photovoltaic module to be flattened by the flattening device, and then the flattened photovoltaic module is fed to the cutting tool by the first roller and the second roller for allowing the back sheet to be separated from the glass sheet assembly by the cutting tool.
