[0029] Furthermore, the movement of the rack 407 causes the limiting strip 409 to slide within the limiting groove 4010, which can improve the stability of the rack 407.

[0030] In this embodiment: a disc 4011 is installed on the outer side wall of the rotating shaft 401, and several long rods 4012 are installed on one side of the disc 4011.

[0031] Furthermore, the rotation of the shaft 401 causes the disc 4011 to drive several long rods 4012 to rotate within the annular groove 4013, which can improve the stability of the rotation of the shaft 401.

[0032] In this embodiment: the cleaning component 5 includes two connecting shafts 501, which are rotatably mounted on both ends of one side of the detection frame 1. The two connecting shafts 501 are fixedly mounted to both ends of the mounting block 502. A connecting pipe 503 is installed on one side of the mounting block 502. One side of the connecting pipe 503 is connected to a high-power vacuum cleaner 504, and the other side of the connecting pipe 503 is connected to a suction pipe 505. Several suction holes 506 are opened at the bottom of the suction pipe 505. A worm gear 507 is installed at one end of one connecting shaft 501. A worm 508 that meshes with the worm gear 507 is rotatably mounted on the detection frame 1.

[0033] Furthermore, two L-shaped brackets are installed on the testing frame 1, and the worm gear 508 is rotatably installed between the two L-shaped brackets, with one side of the worm gear 508 connected to the output end of the servo motor.

[0034] The workflow of this embodiment is as follows: Align and insert the impeller center hole and cylinder 3042. Then, the electric push rod 3044 drives the support plate 3045 to extend, thus securing the impeller. Next, the screw 302 rotates, causing the lifting plate 303 to rise, raising the impeller to the position between the two clamping plates 405 for inspection. The electric cylinder 201 drives the horizontal frame 202, adjusting the distance between the industrial high-definition camera 205 and the impeller to meet different shooting requirements. Simultaneously, the screw 203 rotates, causing the screw block 204 to move laterally, adjusting the horizontal position of the industrial high-definition camera 205. The drive motor 3041 drives the cylinder 3042 to rotate, causing the impeller to rotate, allowing the industrial high-definition camera 205 to capture images of different positions on the impeller surface. The operator can then observe the high-definition detailed images of the impeller surface on the monitor 206, facilitating the detection of surface defects. After one side of the impeller is inspected, the bidirectional threaded rod 404 rotates, causing the two clamping plates 405 to move closer together to clamp the impeller. Then, the support plate 3045 retracts, releasing the clamping of the impeller. The rotation of rod 302 causes the lifting plate 303 to descend, dislodging the cylinder 3042 from the impeller. Then, the electric telescopic rod 406 drives the rack 407 to extend, causing the gear 408 to rotate the shaft 401 180 degrees. This causes the long plate 402 to flip the impeller, and the cylinder 3042 rises again into the impeller's central hole. The support plate 3045 then tightens and secures the impeller, allowing for inspection of the other side of the impeller. This eliminates the need for manual flipping, saving labor. Before inspection, the worm gear 508 drives the worm wheel 507 to rotate... The connecting shaft 501 rotates 90 degrees, causing the mounting block 502 to drive the connecting pipe 503 to rotate 90 degrees, causing the suction pipe 505 to rotate to the upper side of the impeller. Then, the high-power vacuum cleaner 504 is started, creating negative pressure in the suction hole 506 to suction dust from the impeller surface. Then, the drive motor 3041 drives the cylinder 3042 to rotate, causing the impeller to rotate. This allows the suction hole 506 to suction dust from different positions on the impeller surface, improving the suction effect. By suctioning, some impurities can be avoided from affecting the shooting effect and the testing effect.
