[0024] During use, after the stamping machine completes the processing of the workpiece, the electromagnetic suction cup 9 is moved above the workpiece by driving the rotation and lowering of the column 6, and the magnetic force generated by the electromagnetic suction cup 9 when it is energized facilitates the magnetic suction and unloading of the workpiece, thereby reducing the labor intensity of the workers and increasing practicality.

[0025] Furthermore, the connecting arm 7 includes arm 1 701 and arm 2 702. Arm 1 701 is fixedly connected to the column 6, and arm 2 702 is fixedly connected to the fixed frame 8.

The push rod end of the electric cylinder 16 passes through the cover 15 and is fixedly connected to the arm 2 702. By driving the push rod of the electric cylinder 16 to extend and retract, the arm 2 702 can be driven to move, and then the length of the connecting arm 7 can be adjusted, thereby increasing the flexibility of using the connecting arm 7.

[0026] Furthermore, guide grooves 7021 are symmetrically provided above and below the inside of the second arm 702, and guide rods 17 are symmetrically fixedly installed above and below one side of the first arm 701.

[0031] Working principle: When in use, the feed mechanism is moved to the stamping machine area through the action of the Formosa wheel 3, and the length of the connecting arm 7 is adjusted. Then, when the column 6 is rotated, the electromagnetic suction cup 9 can be moved above the processing part of the stamping machine. After the stamping machine completes the processing of the workpiece, the electromagnetic suction cup 9 is moved above the workpiece by driving the rotation and lowering of the column 6. The magnetic force generated by the power supply of the electromagnetic suction cup 9 facilitates the magnetic suction and feeding of the workpiece, thereby reducing the labor intensity of the workers.
