[0031] like Figure 5 , Figure 6 As shown, the width of the cylindrical guide mechanism 3 is adjustable. The cylindrical guide mechanism 3 includes a detachable storage box 31 installed on the rack table. The storage box 31 is used to store the columnar parts 1 to be tested. The columnar parts 1 flow into the discharge guide trough 35 one by one from the storage box 31. The storage box 31 includes a storage box side plate. A guide shaft 39 is provided at the bottom of the storage box 31. The storage box side plate can move along the guide shaft 39. The guide shaft 39 is used to adjust the distance between the two side plates of the storage box to accommodate columnar parts 1 of different lengths. A vibrator 36 is installed on the storage box 31 to facilitate the neat arrangement of the columnar parts 1 in the storage box 31. The outlet of the storage box 31 is connected to the inlet of the discharge guide 35. A baffle 32 and a discharge cylinder 34 are provided above the outlet of the storage box 31. A buffer 33 is provided between the baffle 32 and the discharge cylinder 34. The discharge cylinder 34 drives the baffle 32 to move so that only one columnar part 1 flows from the storage box 31 into the discharge guide 35 at a time. The discharge guide 35 is provided with a soft inner wall to avoid scratching the columnar parts. A guide device for pressing the columnar parts between the positioning block 41 and the clamping block 42 is provided at the outlet of the discharge guide 35. The guiding device is a guiding block 37 or a guiding box 38; one end of the guiding block 37 is fixed at the outlet of the discharge guide groove 35, and the other end is tilted downward and close to the positioning block 41 and the clamping block 42 in the positioning device 4 being loaded; the guiding box 38 is connected to the outlet of the discharge guide groove 35, and the outlet of the guiding box 38 is close to the positioning block 41 and the clamping block 42 in the positioning device 4 being loaded, and a cylinder for pressing the columnar part 1 between the positioning block 41 and the clamping block 42 is provided in the guiding box 38, and a detection sensor 30 for detecting whether the columnar part 1 is in place is also provided in the guiding box 38. Basic working principle: When the columnar parts 1 roll to the bottom one by one from the storage box 31, the baffle 32 connected to the discharge cylinder 34, driven by the discharge cylinder 34, telescopes, so that the columnar parts 1 flow into the guide box 38 one by one in sequence. Each time the discharge cylinder 34 moves, only one columnar part is allowed to flow out of the baffle 32 and flow into the guide box 38; the detection sensor 30 in the guide box 38 detects that the columnar part is in place, and the cylinder presses the columnar part into the positioning device 4.

Then move to the next inspection area, the sensor senses and identifies, and can use X-rays to perform non-destructive inspection to judge whether it is qualified, or the functional inspection mechanism can judge whether its performance is qualified. After the inspection is completed, it is conveyed to the sorting area by the conveyor belt and sorted by the sorting robot 5.

[0035] like Figure 5As shown, the sorting robot 5 mainly includes a cylinder, a sorting claw, a base, etc. Its main function is to receive the sorting signal and sort the columnar parts on the positioning device into qualified and unqualified ones. After the sorting is completed, the positioning device is pushed back to the conveyor belt on the other side by the cylinder, and then transferred back to the loading place, and then waits for the cylinder to push back the conveyor belt on this side to prepare for the next loading, and repeats the above process to realize the station self-circulation detection.
