Metal plate purging system and method

The invention discloses a metal plate blowing system and method.The metal plate blowing system comprises a roller way frame, a roller way used for conveying metal plates is arranged on the roller way frame, a supporting frame is arranged on the upper surface of the roller way frame, a mounting plate is fixed to the top end of the supporting frame, and a plurality of scanning mechanisms and blowing devices are arranged on the lower surface of the mounting plate; the mounting plate is further provided with a driving mechanism used for adjusting the angle of the scanning mechanism, the surface of the metal plate is scanned through the scanning mechanism below the mounting plate, targeted multiple purging is conducted through the purging device after residual defect chips are found, the residual defect chips on the surface of the metal plate can be removed, and the cleaning efficiency is improved. And the metal plate is prevented from being rolled into or adhered to the surface of the plate, and the production qu
