It should be noted that the workpiece 200 is transported from the delivery chute 10 to the first fixture 20, enters through the first inlet end 211 of the first passage 21, and is ready to enter the first inspection section 212 under the urging of the subsequent workpiece 200. The width of the narrowest portion of the first sensing section 212 is set to a first predetermined size so that the workpiece 200 having a size larger than the first predetermined size cannot pass through the first sensing section 212. The workpiece 200 that cannot pass through the first inspection section 212 is retained at the first inlet 211, and the first material moving assembly 24 moves the workpiece 200 to separate from the first inlet 211 through the inspection results of the first inlet sensor 22 and the first outlet sensor 23, so that other subsequent workpieces 200 enter the first inlet 211 for screening.

When the second inlet sensor 32 detects the presence of the workpiece 200 and the corresponding second outlet sensor 33 does not detect the workpiece 200, it indicates that the workpiece 200 is stagnated at the second inlet port 311. At this time, the controller controls the second checking fixture 30 to move, so that another second channel 31 is connected with the first outlet end 213, and simultaneously drives the second material moving assembly 34 to remove the workpiece 200 which is stopped at the second inlet end 311.
