At present, in the industry, the sheet separation operation is carried out manually, or the aluminum plate unstacking separation is carried out by adopting a mechanical saw blade sheet separation or air blowing sheet separation mode. The mechanical saw blade is easy to generate fine broken aluminum scraps after being separated, and once the broken aluminum scraps enter a die, the quality of parts and the loss of the die are brought. At present, air blowing separation is widely applied to aluminum plate unstacking, but because oil films and air negative pressure commonly exist between plates, the traditional cylindrical air blowing device is poor in separation effect, and the probability of double-material line stop is greatly increased. In order to improve the reliability of separation, a linear air blowing separation device is integrated in a magnetic separation device of a steel plate and used for unstacking and separating aluminum plates.
