After transmitting the signals to the controller 2, the controller 2 determines whether there are missing components on the valve stem; when it is detected that there are missing components on the valve stem, when the valve stem passes by the air blowing pump 17, the controller 2 drives the valve stem to operate, blowing the defective products into the recycling hopper 18, so that the valve stems passing through the conveying device are determined to have good product quality after passing the inspection.

[0033] The valve stems are successively placed on the conveying device and are transported along with the conveying device. After being guided by the limiting plate 4, the first detection head 11 identifies the placement state of the valve stems, and then the driving linear motor 13 and the two-axis pan-tilt 16 drive the second detection head 14 to completely identify the appearance of the products. After the controller 2 determines the defective products, it drives the air pump to blow the valve stems into the recycling hopper 18, which has the advantage of saving human resources.
