The invention discloses a
stamping method. The
stamping method is achieved through a
stamping module, a U-shaped support is used as a supporting frame, the distance between the front wall and the rear wall of the U-shaped support is 100mm, and the module comprises an
electromagnet, a lever mechanism, a stepping motor, a stepping motor gear, a stamp roller gear, a stamp roller, an ink storage roller, a photovoltaic module, an anti-dazzling screen, a stamp supporting board and a cooling fan. Firstly, the module is arranged, then an upper control computer sends a stamping command, the computer outputs control signals to a
single chip microcomputer system through an interface, the
single chip microcomputer system processes the received signals to control the stepping motor to rotate and control the
electromagnet to work, so that the stamping action required by information
authentication is completed and stamping is achieved. The stamping method is simple in operation, easy to learn, low in operation threshold and short in consumed
work time, lowers manpower burden, and improves information checking efficiency. The stamping module used in the stamping method is low in
energy consumption, low in
noise, reasonable in cost, and easy to popularize on large scale.
