At this time, the lowest annular hardware is not subjected to the pressure of the various annular hardware above. When the two detection lifting mechanisms are lifted to a specified height, the wall cleaning scraper is controlled to move horizontally to fit on the inner wall and outer wall of the lowest annular hardware, and then the two detection lifting shafts are controlled to rotate in the opposite direction by the lifting motor, so that the two detection lifting mechanisms gradually move downward and reset. In this process, the driving gear is driven to rotate through the downwardly moved meshing portion, and the rotation of the driving roller is used to drive the lowest annular hardware to rotate, and the scraping of debris on the inner and outer walls of the annular hardware is achieved by the wall cleaning scraper, thereby effectively avoiding the decrease in the accuracy of the detection result due to the presence of debris.
[0015] 2. After the two detection and lifting mechanisms are controlled to move downward and reset, the present invention controls the wall cleaning scraper to move in the opposite direction to the initial position, and then controls the two detection mounting seats to approach each other until the image collector is close to the annular hardware in the curved surface positioning groove, and then controls the two detection and lifting mechanisms to move upward to the specified height synchronously. In this process, the upward meshing portion is used to drive the driving gear to rotate, and the rotation of the driving roller drives the lowest annular hardware to rotate. The image information collected by the image collector is transmitted to the graphics processing system for defect analysis. After the annular hardware that has been inspected is unloaded, the two horizontal bearing seats are controlled to approach each other until they are re-attached together, and then the first electromagnet is continuously controlled to be energized and magnetized so that the relatively arranged detection lifting rods are completely separated. At this time, each vertically arranged annular hardware is synchronously moved down to fit in the curved surface positioning groove, and then the first electromagnet is controlled to be powered off and demagnetized so that the relatively arranged detection lifting rods are re-attached together. The same control method as above can be used to achieve all-round detection of the next annular hardware again.
[0016] 3. According to the present invention, after the first electromagnet is energized and magnetized, the second moving part is driven by the magnetic repulsion force to synchronously move and compress the third elastic part, thereby realizing the complete separation of the relatively arranged detection lifting rods. After the detection lifting rods are separated from each other, a plurality of annular hardware components can be placed in sequence between the two vertical guide rails. When a certain number of annular hardware components are placed in sequence between the two vertical guide rails, the first electromagnet is controlled to be powered off and demagnetized, and the elastic restoring force of the third elastic component is used to make the relatively arranged detection lifting rods fit together again. At this time, the position of the annular hardware components above the lowest annular hardware components is limited. At this time, the entire detection lifting mechanism is controlled to move upward along the vertical guide rail, so that the annular hardware components above the detection lifting rods can be moved upward and separated from the lowest annular hardware components, so as to relieve the gravity pressure of the upper annular hardware components on the lowest annular hardware components.

Two detection lifting rods 402 are symmetrically fixedly arranged on the first moving part 401. After the detection lifting rods 402 are controlled to be horizontally inserted into the bottom of the corresponding annular hardware 3, the annular hardware 3 in the curved surface positioning groove 203 is separated from the annular hardware 3 above it by moving the detection lifting mechanism 4 upward, so that it is convenient to control the rotation of the annular hardware 3 at the position of the curved surface positioning groove 203, and the surface defect detection is completed by the rotation of the annular hardware 3; The detection control mechanism 5 is fixedly installed on the detection supporting mechanism 2. The detection control mechanism 5 includes a wall cleaning scraper 501 that moves horizontally back and forth and two detection mounting seats 502 that move toward each other. A group of image collectors 503 (image acquisition probes can be used in this application) are installed inside the detection mounting seats 502. After the debris on the surface of the corresponding annular hardware 3 is removed by the wall cleaning scraper 501, the two detection mounting seats 502 are controlled to approach each other until the image collector 503 is close to the annular hardware 3 in the curved surface positioning groove 203. The surface defect detection of the annular hardware 3 is achieved by controlling the rotation of the annular hardware 3.

In an initial state, the two horizontal bearing seats 202 are in close contact with each other, and the first elastic member 211 is in a natural state. When the interiors of the two relatively arranged hollow flow boxes 207 are controlled to be in a negative pressure environment, the two relatively arranged horizontal bearing seats 202 can be separated from each other. During this process, the first elastic member 211 is compressed. When the interiors of the two hollow flow boxes 207 are controlled to restore the normal air pressure, the elastic restoring force of the first elastic member 211 can be used to realize the movement and reset of the horizontal bearing seats 202, that is, the two horizontal bearing seats 202 are again in close contact with each other.
[0035] In this embodiment of the present invention, a limit guide rod 212 is horizontally slidably arranged on the first support frame 206, a U-shaped mounting portion 213 is fixedly arranged at one end of the limit guide rod 212, the driving roller 204 and the positioning roller 205 are respectively rotatably arranged inside the corresponding U-shaped mounting portion 213, a third mounting plate 214 is fixedly arranged on the side surface of the limit guide rod 212, the third mounting plate 214 is connected to the corresponding first support frame 206 through a second elastic member 215, and a guide channel 216 communicating with its inner cavity is opened on the surface of the vertical guide rail 201; each second elastic member 215 is in a self-locking state in the initial state. In this state, the surface of the driving roller 204 is set to an anti-slip structure, and the surface of the positioning roller 205 is set to a smooth structure. After the annular hardware 3 is placed between the two vertical guide rails 201 in sequence, the gravity of the annular hardware 3 is used to squeeze the driving roller 204 and the positioning roller 205 below it, so that the driving roller 204 and the positioning roller 205 move away from each other and compress the corresponding second elastic member 215 until the lowest annular hardware 3 is fitted into the curved positioning groove 203. At this time, the driving roller 204 and the positioning roller 205 are both tightly attached to the outer wall of the lowest annular hardware 3.
[0036] In this embodiment of the present invention, the detection and lifting mechanism 4 also includes a second support frame 403, and a positioning portion 404 is fixedly provided on the inner wall of the second support frame 403. The positioning portion 404 is slidably arranged inside the corresponding guide channel 216. Through this structural design, the entire detection and lifting mechanism 4 can be ensured to slide up and down smoothly along the vertical guide rail 201. One end of the detection and lifting rod 402 slides through the outer side of the second support frame 403 and is fixed with a second moving portion 405.

The first electromagnet and the first permanent magnet on the corresponding second moving portion 405 repel each other magnetically. When controlling the first electromagnet After power is supplied to the magnet, the second moving part 405 is driven by the magnetic repulsion force to synchronously move the first moving part 401 to compress the third elastic member 406, thereby realizing the complete separation of the relatively arranged detection lifting rods 402. After the detection lifting rods 402 are separated from each other, a plurality of annular hardware components 3 can be placed in sequence between the two vertical guide rails 201. When a certain number of annular hardware components 3 are placed in sequence between the two vertical guide rails 201, the first electromagnet is controlled to be powered off and demagnetized, and the elastic restoring force of the third elastic member 406 is used to make the relatively arranged detection lifting rods 402 fit together again. At this time, the position of the annular hardware component 3 above the lowest annular hardware component 3 is limited. At this time, the entire detection lifting mechanism 4 is controlled to move upward along the vertical guide rail 201, so that the annular hardware components 3 above the detection lifting rod 402 can be moved upward and separated from the lowest annular hardware component 3, so as to relieve the gravity pressure of the upper annular hardware components 3 on the lowest annular hardware component 3.

Under the joint action of the pulley 218 and the transmission belt 7, the two detection lifting shafts 217 can rotate synchronously, thereby realizing the synchronous up and down movement of the two detection lifting mechanisms 4.
[0038] In this embodiment of the present invention, a lifting seat 407 is fixedly provided on the outer wall of the second support frame 403 and is sleeved on the corresponding detection lifting shaft 217. The lifting seat 407 is threadedly matched with the corresponding detection lifting shaft 217. A horizontal limit groove 408 is opened on one side of the lifting seat 407, and a fourth mounting plate 409 is fixedly provided on the side of the lifting seat 407 close to the horizontal limit groove 408; a downwardly extending meshing portion 410 is slidably provided inside the horizontal limit groove 408, and the meshing portion 410 is connected to the fourth mounting plate 409 through a fourth elastic member 411. A driving gear 220 is fixedly installed on the end of the connecting shaft corresponding to the driving roller 204, and the driving gear 220 is meshed with the meshing portion 410. Under the elastic force of the fourth elastic member 411, the meshing portion 410 is tightly meshed with the driving gear 220.
[0039] After the first electromagnet is energized and magnetized, the second moving part 405 is driven by the magnetic repulsion force to drive the first moving part 401 to move synchronously and compress the third elastic part 406, thereby achieving the complete separation of the relatively arranged detection lifting rods 402, and then a certain number of annular hardware pieces 3 are placed between the two vertical guide rails 201 in sequence. At this time, the lowest annular hardware piece 3 is matched inside the curved surface positioning groove 203, and the driving roller 204 and the positioning roller 205 are both tightly attached to the outer wall of the lowest annular hardware piece 3, and then the first electromagnet is controlled to be powered off and demagnetized so that the relatively arranged detection lifting rods 402 are reattached together, thereby achieving the position limitation of the annular hardware piece 3 above the lowest annular hardware piece 3; Then, the corresponding detection lifting shaft 217 is driven to rotate by the lifting motor 219. Under the joint action of the pulley 218 and the transmission belt 7, the two detection lifting shafts 217 can be rotated synchronously. The threaded cooperation between the detection lifting shaft 217 and the lifting seat 407 is utilized to make the two detection lifting mechanisms 4 move upward synchronously to lift the various annular hardware pieces 3 above the lowest annular hardware piece 3. At this time, the lowest annular hardware piece 3 is not subjected to the pressure of the various annular hardware pieces 3 above. When the two detection lifting mechanisms 4 are lifted to the index position, the detection lifting shaft 217 and the lifting seat 407 are screwed together. When the height is set, the wall cleaning scraper 501 is controlled to move horizontally to fit on the inner and outer walls of the lowest annular hardware 3, and then the two detection lifting shafts 217 are controlled to rotate in the opposite direction by the lifting motor 219, so that the two detection lifting mechanisms 4 gradually move downward to reset. In this process, the driving gear 220 is driven to rotate by the downwardly moving meshing portion 410, and the rotation of the driving roller 204 drives the lowest annular hardware 3 to rotate (using friction), and the debris on the inner and outer walls of the annular hardware 3 is scraped off by the wall cleaning scraper 501; After the two detection lifting mechanisms 4 are controlled to move downward and reset, the wall cleaning scraper 501 is controlled to move in the opposite direction to the initial position, and then the two detection mounting seats 502 are controlled to approach each other until the image collector 503 is close to the annular hardware 3 in the curved surface positioning groove 203, and then the two detection lifting mechanisms 4 are controlled to move upward to the specified height synchronously. In this process, the upwardly moved meshing portion 410 is used to drive the driving gear 220 to rotate, and the rotation of the driving roller 204 drives the annular hardware 3 at the bottom to rotate, and the image information collected by the image collector 503 is transmitted to the graphics processing system for defect analysis; After completing the inspection of the bottom ring-shaped hardware 3, the two inspection lifting mechanisms 4 are controlled to move downward again to complete the reset, and then the two inspection mounting seats 502 are controlled to move away from each other until they return to the initial position, and then the two horizontal supporting seats 202 are controlled to separate from each other to release the support for the ring-shaped hardware 3 that has completed the inspection (i.e., the bottom ring-shaped hardware 3).
