Unattended full-automatic perforating method and device

The invention relates to the field of perforating machines, and discloses an unattended full-automatic perforating method and device.The unattended full-automatic perforating method comprises the steps that when an electrode needs to be replaced, the electrode enters a hollow rotating shaft of a rotating head; controlling the electrode to carry out discharge perforation processing on the workpiece, receiving information that the electrode penetrates out of the lower surface of the workpiece by utilizing a penetration detection system, controlling the electrode to exit from the workpiece and processing a next hole; the mode of enabling the electrodes to enter the hollow rotating shaft of the rotating head at least comprises the following mode that the electrodes in the first electrode library are fed into the hollow rotating shaft of the rotating head from top to bottom in an automatic mode. By utilizing the penetration detection system, the problems of electrode waste and workpiece and puncher damage caused b
