Columnar parts 700 (e.g., pins) are fed by an automatic feeder or manually and placed on tooling blocks 150 opposite the feed end of the conveyor 100. The power output of the power source 110 is transmitted to the chain 140 through the driving chain wheel set 120, and the tool block 150 is driven by the chain 140 to enable the columnar part 700 to move towards the discharging direction. The power source 110 outputs twice as much time as the tooling block 150 moves to the adjacent position, preferably twice as much in this embodiment, and both parts can be inspected simultaneously. The time for each stop of the power source 110 is preferably 1.5s in this embodiment, which is the time for the side vision detection. When the columnar part reaches a preset end face visual detection station, the movement of the chain 140 is stopped, the annular light 212 is lighted, the industrial camera 211 shoots, and the obtained picture is transmitted to a connected upper computer for defect identification. After the end face visual inspection is completed, the columnar part 700 moves forward, and when the columnar part reaches the position right above the lifting detection mechanism 400, after the chain 140 stops moving, the pneumatic sliding table 420 is lifted, the workpiece is jacked up, and the workpiece is separated from the tooling block 150 and is in direct contact with the roller shaft 440.

After the rotation is stable, the strip light 312 is lighted, the side light supplementing module 330 is supplemented with the lighting, the shooting time of the line scanning camera 311 is longer than the rotating time of the columnar part 700 to obtain a complete side picture, and the obtained picture is transmitted into a connected upper computer for defect identification. After the side vision inspection is completed, the pneumatic sliding table 420 descends, and the parts stopped to rotate are put back on the tooling block 150. The tooling block 150 continues to move forward with the chain 140 to the rejection station, at which time the upper computer determines whether to reject the part according to the results given by the algorithm. If the part is removed, the removing cylinder 520 is lifted, and the removing block 510 pushes the columnar part 700 to be removed under the action of the removing cylinder 520, so that the columnar part 700 falls into the removing bin 530; if the part is not rejected, the part continues to move forward. After the columnar member 700 reaches the discharge end of the conveying mechanism 100, it falls to the discharge chute 630 due to gravity. The number of columnar parts 700 to be stacked reaches a predetermined value, and the pushing cylinder 640 will push the cylinder push plate 650 to align the parts, preferably 15 in this embodiment. At this time, the whole detection process is completed, and the columnar parts 700 are stacked in order on the discharge slideway 630, and waiting for the subsequent process.
