[0024] The driving member 11 includes a driving motor 37 fixedly mounted on the base 1. The model of the driving motor 37 is preferably YYHS-40. The output end of the driving motor 37 is coaxially fixedly connected to the second gear 38. The second gear 38 is engaged with the first gear 27. Two sets of electric telescopic rods 39 are fixedly connected to the fixed frame 2. The two sets of electric telescopic rods 39 are symmetrically distributed on both sides of the first gear 27.

[0025] The rotating member 5 includes multiple groups of connecting shafts 30 rotatably connected to the connecting frame 26, a second transmission belt 31 is connected between adjacent connecting shafts 30, the second pulley 28 is connected to a third transmission belt 32 that is connected to an adjacent group of connecting shafts 30, and the positioning plate 4 is rotatably connected to multiple groups of conveying cylinders 33, and the inner wall of the conveying cylinder 33 is connected to the outer wall of the connecting shaft 30 in a horizontal sliding direction.

[0026] The grabbing mechanism includes a feed trough 34 fixedly mounted on one end of the base 1. A robotic arm 35 is provided on the base 1 for grabbing and conveying the rotating shaft 41 at one end of the feed trough 34. Sliding frames 14, push plates 15, springs 16, drive rods 17 and sleeves 22 are also provided on both sides of the feed trough 34. The sliding frame 14 is connected to the surface of the feed trough 34 in a horizontal sliding direction. One end of the sleeve 22 is connected to a hose 36 connected to the output pipe 21. An output bucket 40 is fixedly connected to the base 1. The output bucket 40 is located at the end of the base 1 away from the feed trough 34.

[0027] In this embodiment, according to the size range of the rotating shaft 41 to be detected, the electric telescopic rods 39 on both sides are controlled to drive the fixed box 13 and the positioning plate 4 to slide horizontally, and the spacing between the triangular blocks 9 on both sides is adjusted so that the spacing between the triangular blocks 9 at symmetrical positions on the rotating frames 8 on both sides is slightly smaller than the length of the shortest rotating shaft 41, thereby ensuring that all the rotating shafts 41 can be lifted and conveyed during the rotation of the rotating frame 8, and the rotating shaft 41 to be detected is placed in the feeding trough 34, and the rotating shaft 41 rolls to the bottom position. The rotating shaft 41 is grabbed by the mechanical arm 35 and lifted to the set position, and the driving motor 37 is started to drive the second gear 38 to rotate. The second gear 38 drives the first gear 27 to rotate the driving columns 29 on both sides, and the driving column 29 drives the driving cylinder 25 on the outer wall to rotate synchronously, so that the first pulley 23 and the rotating disk 6 can rotate. The first pulleys 23 on both sides maintain synchronous transmission operation through the first transmission belt 24, so that the rotating frame 8 can continue to operate stably under the drive of the rotating disk 6.

[0028] It is worth noting that: when adjusting the spacing of the positioning plates 4, the driving cylinder 25 and the conveying cylinder 33 on the positioning plates 4 on both sides will be synchronously driven to slide horizontally, changing the relative positions between the driving cylinder 25 and the driving column 29, and the conveying cylinder 33 and the connecting shaft 30, but it can always be ensured that the driving column 29 can drive the driving cylinder 25 to rotate synchronously, and the connecting shaft 30 can drive the conveying cylinder 33 to rotate synchronously.

[0029] In the process of the rotating frame 8 driving the triangular block 9 to rotate, the rotating shaft 41 on the robotic arm 35 is transported to the top of the two adjacent groups of conveying cylinders 33 for placement. At the same time, driven by the second pulley 28, the connecting shaft 30 is driven to rotate by the third transmission belt 32, so that the conveying cylinder 33 is rotated. The conveying cylinder 33 is synchronously driven by the second transmission belt 31, and the rotating shaft 41 installed above can be driven to complete unidirectional rotation. The multiple groups of visual inspection instruments 3 arranged above can be used to visually inspect the rotating shaft 41 during the rotation process. In order to avoid errors in a single inspection, multiple groups of visual inspection instruments 3 are arranged in the fixed frame 2, which can perform multiple inspections on the rotating shaft 41 during the transportation of the rotating shaft 41. The inspection results are obtained through data comparison and analysis to improve accuracy.

[0030] During the rotation of the rotating disk 6, the connecting rod 20 is driven to rotate by the driving shaft 7, so that the sliding plate 19 performs piston motion in the fixed box 13, changing the volume in the fixed box 13 so that the gas pressure changes. When the driving shaft 7 rotates until the center of the rotating disk 6 gradually rotates downward, the rotating shaft 41 on the rotating frame 8 has been placed on the conveying cylinder 33 at the corresponding position. The connecting rod 20 will gradually push the sliding plate 19 to compress the gas in the fixed box 13, thereby pushing the gas into the output pipe 21, and then transporting it to the desired position through the hose 36 and the sleeve pipe 22, pushing The driving rod 17 slides out, causing the sliding frames 14 on both sides to slide synchronously toward the two ends of the rotating shaft 41, and the two ends of the rotating shaft 41 are resisted by the pushing plate 15, so that the rotating shaft 41 is reset to a relatively centered position. When the driving shaft 7 rotates 180° and gradually rotates upward from the center position of the rotating disk 6, the rotating frame 8 gradually lifts the rotating shaft 41, and the sliding plate 19 slides in the opposite direction, and the gas in the sleeve 22 is reversely drawn into the fixed box 13, so that the sliding frame 14 slides synchronously to both sides, releasing the squeeze on the rotating shaft 41, making it easier for the triangular block 9 to lift and transport the rotating shaft 41.

[0031] The device can synchronously control the sliding state of the sliding plate 19 according to the position of the rotating frame 8 during the rotation of the rotating disk 6, so that when the triangular block 9 is needed to lift the rotating shaft 41, the pushing plates 15 on both sides are controlled to release the interference state of the two ends of the rotating shaft 41. After the rotating shaft 41 is placed on the conveying cylinder 33, the pushing plate 15 is controlled to center the position of the rotating shaft 41, thereby improving the stability during subsequent conveying. At the same time, by arranging the pushing plate 15 in the feeding trough 34, the rotating shaft 41 in the input state can also be preliminarily centered. By arranging the spring 16 in the sliding frame 14 for buffering and pushing by air pressure, it is ensured that the rotating shafts 41 of different lengths can be pushed to the center, and the clamping too tight to damage the rotating shaft 41 body is avoided. After the detection is completed, the rotating shaft 41 will be conveyed by the triangular block 9 to the top inclined surface of the output bucket 40 to roll down, completing the output operation.
