When the correction work is completed, the vacuum mechanism is operated so that the suction holes 622 can suck the corrected product 100, and then the turntable driving motor 64 is operated so that the turntable 62 can continue to rotate. When the turntable 62 rotates 90 degrees to reach the detection station, the third sensor 98 can detect that the product 100 is arranged above the turntable, so that the turntable driving motor 64 stops working, the turntable 62 stops working, and the detection of the transmittance of the functional hole of the product 100 can be realized through the detection mechanism 80 and the computer. After the detection is completed, the turntable driving motor 64 is started to work, so that the turntable 62 can continue to rotate, when the turntable 62 rotates 90 degrees to reach the blanking station, the fourth sensor 99 can detect that the product 100 is arranged above the turntable, the turntable driving motor 64 stops working, the vacuumizing mechanism stops working, the turntable 62 stops working, the air suction holes 622 stop adsorbing the product 100, the blanking manipulator 50 can perform blanking work, and the qualified product 100 can be placed on the blanking disc 104 or the unqualified product 100 can be placed on the NG disc 106.
