[0039] The working process of the present invention is as follows:

[0040] First, the short straight-axis workpiece to be tested is placed on the vibrating plate 11. Under the vibration of the vibrating plate 11, the short straight-axis workpiece to be tested enters the sorting box 21 from the feed port 213 along the loading track 12, and then the short straight-axis workpiece to be tested rolls along the first slope 211 to the edge of the first sorting plate 22. If its diameter is smaller than the width of the first screening trough 221, it will enter the first screening trough 221 and rotate to the bottom of the first sorting plate 22 as the first sorting plate 22 rotates. When the slot is aligned with the blanking port 214, the workpiece will fall from the blanking port 214 to the side of the third slope 215. If its diameter is larger than the width of the first screening trough 221, it will rotate with the first sorting plate 22. The disk 22 rotates and rolls to the side of the second slope 212, and rolls out of the sorting box from the first discharge port 217 as an unqualified workpiece; for the short straight-axis workpiece that falls to the side of the third slope 215, if its diameter is greater than the width of the second screening trough 231, it is a qualified workpiece to the side of the fourth slope 216 as the second sorting disk 23 rotates, and then rolls out from the second discharge port 218 along the slope, rolls out along the conveying channel 24, and rolls until it is blocked by the card slot 25. If the diameter of the short straight-axis workpiece is smaller than the width of the second screening trough 231, it will enter the second screening trough 231, and as the second sorting disk 23 rotates, it will be sent out from the waste port below the second sorting disk 23.

[0041] For the qualified short straight-axis workpieces to be sorted, the clamping claws 57 of the clamping mechanism clamp them and send them to the conveying mechanism 4. The conveyor belt sends the short straight-axis workpiece to the bottom of the visual inspection device 3 for inspection to see whether there are cracks on its surface. For the workpieces that pass the inspection, the robot grabs them and sends them to the hardness inspection device 6 for hardness inspection. For the workpieces that fail the visual inspection, the conveyor belt continues to transport them to their end. After being blocked by the block 41, the ejection cylinder 43 pushes them into the waste port 7, and then they enter the waste box 9 along the waste flow channel 8. For the workpieces that pass the hardness inspection, the robot puts them into the qualified product box. For the workpieces that fail the hardness inspection, the robot puts them into the waste box.
