[0036] This scheme has the following working process: when flaw detection is performed on the steel cylinder 307, the second cylinder 303 is first started, and the second cylinder 303 is started to push the connecting rods 306 on both sides to rotate, so that the two driving rods 300 rotate, and then the first rotating rod 200 and the second rotating rod 202 rotate clockwise and counterclockwise, and finally the first blocking rod 201 and the second blocking rod 203 are in a horizontal state, and then the steel cylinder 307 is placed between the first blocking rod 201 and the second blocking rod 203, and then the PLC controller 900 controls the output end of the second cylinder 303 to move downward, and finally the first blocking rod 201 and the second blocking rod 203 are reset, and at this time the steel cylinder 307 is located on a plurality of rotating wheels 206, and then the PLC controller 900 controls the second servo motor 402 to rotate, so that the third threaded rod 401 rotates, and the rotation of the third threaded rod 401 drives the mounting bar 403 to move, thereby causing the outer sleeve 404 to move until one side of the natural rubber ring is close to one side of the cylinder 307, and then the PLC controller 900 controls the fourth cylinder 504 to start, and the fourth cylinder 504 starts to push the push plate 505 to move until the push plate 505 pushes the cylinder 307 to move, so that the air inlet end of the cylinder 307 is inserted into the docking hole, and then the second servo motor 402 rotates in the opposite direction to reset the outer sleeve 404. Then the PLC controller 900 controls the external motor 208 to rotate, and drives the two rotating rods 205 to rotate through the transmission of the pulley 209 and the belt 210, thereby rotating the rotating wheel 206, and the steel cylinder 307 rotates on the rotating wheels 206 on both sides. At the same time, the PLC controller 900 controls the first servo motor 106 to rotate, so that the first threaded rod 104 rotates, thereby slowly moving the threaded sleeve 105. The slow movement of the threaded sleeve 105 drives the arc plate 108 to move, and the water at the water source of the water pipe 109 is pumped into the water pipe 109 through the water pump connected to the water pipe 109, and finally discharged into the top surface of the steel cylinder 307. The water slides down the outer wall of the steel cylinder 307, and the four ultrasonic probes 110 perform ultrasonic flaw detection on the steel cylinder 307, and feed the results back to the PLC controller 900. The threaded sleeve 105 moves slowly, so that the outer wall of the steel cylinder 307 can be flaw detected one by one.

During this process, the natural latex ring 502 is unsupported by the moving circle 405, so that the natural latex ring 502 is reset and contracted to be in tight contact with one side of the outer wall of the cylinder 307, and then the second servo motor 402 moves in the opposite direction, so that the cylinder 307 is away from the docking hole, and then the two third cylinders 408 push the moving circle 405 to move outward, so that the natural rubber ring is propped up. At this time, the cylinder 307 is unpositioned, the outer sleeve 404 is reset, and then the fifth cylinder 707 is reset, so that the cylinder 307 is in contact with the rotating wheel 206, and the dual-axis motor 800 rotates in the opposite direction to reset the moving bar 605, and then the PLC controller 900 controls the second cylinder 303 to start, so that the first gear rod 201 and the second gear rod are horizontal, and then the cylinder 307 feeding mechanism takes out the cylinder 307.

[0051] The position of the second rack 706 can be limited by the provided guide column 704 and the movable bar 705 .

[0052] As a further solution of the present invention, a PLC controller 900 is fixed to one side of the first support frame 100, and the second servo motor 402, the third cylinder 408, the fourth cylinder 504, the dual-axis motor 800 and the fifth cylinder 707 are electrically connected to the PLC controller 900 respectively.

[0053] By setting up the PLC controller 900, the whole device can operate in a coordinated manner.

[0054] The first gear rods 201 and the second gear rods 203 are staggered, and the C-shaped rod 409 and the first cylinder 107 are staggered.

[0055] In summary, when flaw detection is performed on the steel cylinder 307, the second cylinder 303 is first started, and the second cylinder 303 is started to push the connecting rods 306 on both sides to rotate, so that the two driving rods 300 rotate, and then the first rotating rod 200 and the second rotating rod 202 rotate clockwise and counterclockwise, and finally the first blocking rod 201 and the second blocking rod 203 are in a horizontal state, and then the steel cylinder 307 is placed between the first blocking rod 201 and the second blocking rod 203, and then the PLC controller 900 controls the output end of the second cylinder 303 to move downward, and finally the first blocking rod 201 and the second blocking rod 203 are reset, and at this time the steel cylinder 307 is in the horizontal state. On a plurality of rotating wheels 206, the PLC controller 900 then controls the second servo motor 402 to rotate, causing the third threaded rod 401 to rotate, and the rotation of the third threaded rod 401 drives the mounting bar 403 to move, thereby causing the outer sleeve 404 to move until one side of the natural rubber ring is close to one side of the cylinder 307, and then the PLC controller 900 controls the fourth cylinder 504 to start, and the fourth cylinder 504 starts to push the push plate 505 to move until the push plate 505 pushes the cylinder 307 to move, so that the air inlet end of the cylinder 307 is inserted into the docking hole, and then the second servo motor 402 rotates in the opposite direction to reset the outer sleeve 404. Then the PLC controller 900 controls the external motor 208 to rotate, and drives the two rotating rods 205 to rotate through the transmission of the pulley 209 and the belt 210, thereby rotating the rotating wheel 206, and the steel cylinder 307 rotates on the rotating wheels 206 on both sides. At the same time, the PLC controller 900 controls the first servo motor 106 to rotate, so that the first threaded rod 104 rotates, thereby slowly moving the threaded sleeve 105. The slow movement of the threaded sleeve 105 drives the arc plate 108 to move, and the water at the water source of the water pipe 109 is pumped into the water pipe 109 through the water pump connected to the water pipe 109, and finally discharged into the top surface of the steel cylinder 307. The water slides down the outer wall of the steel cylinder 307, and the four ultrasonic probes 110 perform ultrasonic flaw detection on the steel cylinder 307, and feed the results back to the PLC controller 900. The threaded sleeve 105 moves slowly, so that the outer wall of the steel cylinder 307 can be flaw detected one by one.

[0056] When the flaw detection of the steel cylinder 307 is completed and the air inlet end of the steel cylinder 307 needs to be taken out from the docking hole, the PLC controller 900 controls the dual-axis motor 800 to rotate, and the dual-axis motor 800 rotates to drive the two second gears 801 to rotate, and the second gear 801 rotates to drive the first rack 607 to move, so that the two moving bars 605 move to between the rotating wheels 206 on both sides, and then the fifth cylinder 707 is started to move the second rack 706, and the movement of the second rack 706 drives the two first gears 702 to rotate, and the rotation of the first gear 702 drives the fourth threaded rod 700 to rotate, thereby causing the L-shaped guide rail 603 to move upward, and at this time, a plurality of second rollers 606 support the steel cylinder 307, so that the steel cylinder 307 is separated from the rotating wheel 206, and then the PLC controller 900 controls the second servo motor 402 to start, so that the outer sleeve 404 is close to the steel cylinder 307, and the moving circle 405 is located outside the steel cylinder 307, wherein the top surface of the second roller 606 is aligned with the top surface of the docking strip 608 The distance is greater than the distance between the inner wall of the moving circle 405 and the outer wall of the outer sleeve 404, and then the PLC controller 900 controls the two third cylinders 408 to start, so that the moving circle 405 moves into the outer sleeve 404. During this process, the natural latex ring 502 is unsupported by the moving circle 405, so that the natural latex ring 502 is reset and contracted to be in tight contact with one side of the outer wall of the cylinder 307, and then the second servo motor 402 moves in the opposite direction, so that the cylinder 307 is away from the docking hole, and then the two third cylinders 408 push the moving circle 405 to move outward, so that the natural rubber ring is propped up. At this time, the cylinder 307 is unpositioned, the outer sleeve 404 is reset, and then the fifth cylinder 707 is reset, so that the cylinder 307 is in contact with the rotating wheel 206, and the dual-axis motor 800 rotates in the opposite direction to reset the moving bar 605, and then the PLC controller 900 controls the second cylinder 303 to start, so that the first gear rod 201 and the second gear rod are horizontal, and then the cylinder 307 feeding mechanism takes out the cylinder 307.

[0057] The first servo motor 106, the first cylinder 107, the ultrasonic probe 110, the external motor 208, the second cylinder 303, the second servo motor 402, the third cylinder 408, the fourth cylinder 504, the fifth cylinder 707, the dual-axis motor 800 and the PLC controller 900 can all be purchased on the market. They are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
