The invention relates to a separate gripping device for metal plates. The separate gripping device comprises a support and a magnetic separation mechanism used for making the contact parts of every two adjacent metal plates provided with same pole magnetism, wherein the magnetic separation mechanism is fixed to the support. The metal plates to be separately gripped are magnetized through the magnetic separation mechanism, so that the contact faces of every two adjacent metal plates have the same pole magnetism, the attached metal plates are separated through the principle of homopolar repellence, and the problems that time and force are wasted and work efficiency is extremely low by the adoption of a manual metal plate separation manner and the metal plates cannot be thoroughly separated, so that potential safety hazards exist in the lifting process by the adoption of a suction cup metal plate separation manner are solved.
