The control unit 90 controls the industrial camera 42 to photograph the angled workpiece 200 and transmits the photographed image to the control unit 90. The control unit 90 analyzes the image to obtain the appearance quality of the workpiece 200 at the angle. The control unit 90 controls the robot 30 to move or rotate so that the image capturing mechanism 40 is aligned at another designated angle with another to-be-inspected position on the workpiece 200 so that the image capturing mechanism 40 photographs the workpiece 200 at the angle and transmits the workpiece to the control unit 90 for analysis processing. The previous step is circulated until the image capturing mechanism 40 finishes capturing all the positions to be inspected on the workpiece 200. The control unit 90 controls the lifting drive member driving seat plate 63 and the plurality of carrier rods 64 to descend to drop the carrier member 20 onto the transfer mechanism 50, and at the same time, the control unit 90 controls the main body 71 to retract into the output shaft 72. The conveying mechanism 50 conveys the carrier 20 and the workpiece 200 to a blanking position, and the detection unit 80 detects the blanking and feeds back the blanking to the control unit 90. This completes the inspection work of the appearance of one workpiece 200.

It is understood that the appearance inspection device 100 may omit the conveying mechanism 50, and the loading member 20 is directly placed on the top bar 64 of the jacking mechanism 60.

It is understood that the appearance inspection device 100 may omit both the conveying mechanism 50 and the jacking mechanism 60, and the loading member 20 is directly placed on the rack 10.
