Since the air port is arranged directly above the discharge port, the torn QR code can be rotated directly above the discharge port. Therefore, after the rotating pneumatic cylinder rotates 90 degrees and the vacuum air pump stops vacuuming, the QR code adsorbed on the air port can be released and fall, so that it falls into the discharge port and completes the discharge.

[0046] The rotating code tearing mechanism can tear off the QR code on the electronic product workpiece to be torn off installed on the workpiece mounting table through the air port, and then rotate the fallen code so that it is located above the discharge port and the vacuum pump stops vacuuming, so that the QR code falls off the air port and is removed from the device. Through the setting of the air port, the mechanical code tearing structure is reduced to ensure the safety of the equipment during the code tearing operation.
