[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the image acquisition module 12 is vertically aligned with the circumference of the through hole 4. When the placement cylinder 7 moves the image acquisition module 12 past the through hole 4, the image acquisition module 12 faces the grinding wheel and can acquire images of both sides of the grinding wheel. When the placement cylinder 7 rotates, the image acquisition module 12 is located behind the placement cylinder 7 in the direction of rotation. Figure 1 and Figure 2 In one embodiment, the placement cylinder 7 and the image acquisition module 12 rotate clockwise.
[0025] like Figure 1 ,Figure 3 and Figure 9 As shown, the steering assembly 9 includes a driving bevel gear 33 and a driven bevel gear 34. The driven bevel gear 34 is located at the outer end of the rotating shaft 18, and the driving bevel gear 33 is located at the upper end of the linkage shaft 16. The driving bevel gear 33 meshes with the driven bevel gear 34.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the rotating assembly 8 includes a drive gear 35, a drive shaft 36, a motor 37, and a gear ring 38. The gear ring 38 is mounted on the upper wall of the rotating ring 13 via a support column 43. The drive shaft 36 passes through the upper wall of the operating table 1. The drive gear 35 is located at the upper end of the drive shaft 36. The motor 37 is located on the lower wall of the operating table 1 and is connected to the lower end of the drive shaft 36. The motor 37 is electrically connected to an external controller.
[0027] like Figure 1 , Figure 5 and Figure 6 As shown, the lower outer wall of the placement cylinder 7 is fixed to the inner wall of the rotating ring 13 by the connecting plate 39.
[0028] like Figure 1 and Figure 10 As shown, the pressing assembly 11 includes an upper cover 40, a pressing spring 41, and a pressing plate 42. The upper cover 40 is detachably disposed at the upper port of the placement cylinder 7. The upper end of the pressing spring 41 is disposed at the middle of the lower wall of the upper cover 40, and the pressing plate 42 is disposed at the lower end of the pressing spring 41.
[0029] In actual use, in the initial state, the placement cylinder 7 is located on the upper wall of the operating table 1 and offset from the through hole 4. At this time, the rotating arm 19 and the semi-ring body 21 are in a horizontal state, and the rotating arm 19 and the semi-ring body 21 are respectively in the through groove 5 and the through hole 4. Remove the upper cover 40, put the stacked grinding wheels into the placement cylinder 7, and then install the upper cover 40 on the upper end of the placement cylinder 7. The lower pressure spring 41 pushes the lower pressure plate 42 downward, and the lower pressure plate 42 presses the grinding wheels tightly. Turn on the motor 37. The motor 37 drives the drive shaft 36 to rotate, the drive shaft 36 drives the drive gear 35 to rotate, the drive gear 35 drives the gear ring 38 to rotate, the gear ring 38 drives the support column 43 to rotate, the support column 43 drives the rotating ring 13 to rotate, and the rotating ring 13 drives the gear teeth 14 and the placement cylinder 7 to rotate. Simultaneously rotating, as the rotating ring 13 drives the connecting plate 39 and the placement cylinder 7 to rotate, the placement cylinder 7 drives the grinding wheel to rotate to the through hole 4, aligning the grinding wheel with the ring formed by the two semi-ring bodies 21. At this point, the motor 37 stops, the placement cylinder 7 stops rotating, and the downward spring 41 pushes the grinding wheel downward, so that the bottom grinding wheel enters the ring formed by the semi-ring bodies 21, squeezing the elastic rubber layer 25, thus fixing the grinding wheel within the ring formed by the semi-ring bodies 21. The motor 37 rotates again, and the placement cylinder 7 drives the remaining grinding wheels to continue rotating. As the placement cylinder 7 rotates out of the through hole 4, the image acquisition module 12 takes a picture of the front of the grinding wheel within the ring formed by the two semi-ring bodies 21 to determine if there are any defects in the grinding wheel. When the placement cylinder 7 rotates out of the through hole 4... At this time, gear 14 and linkage gear 15 begin to mesh, gear 14 drives linkage gear 15 to rotate, linkage gear 15 drives linkage shaft 16 to rotate, linkage shaft 16 drives driving bevel gear 33 to rotate, driving bevel gear 33 drives driven bevel gear 34 to rotate, driven bevel gear 34 drives rotating shaft 18 to rotate, rotating shaft 18 drives rotating arm 19 to rotate, rotating arm 19 drives semi-ring body 21 to rotate, thereby driving the grinding wheel to rotate 180 degrees, and the grinding wheel is flipped. The placement cylinder 7 drives the image acquisition module 12 to continue to rotate. The placement cylinder 7 passes through the through hole 4 again. During the process of rotating out of the through hole 4, the image acquisition module 12 takes another picture of the reverse side of the grinding wheel for inspection. In the two picture inspections, when it is determined that any side of the grinding wheel has a defect or both sides have defects, the image acquisition module 12 takes another picture of the reverse side of the grinding wheel for inspection. When a defect is detected, motor 2 (31) starts and drives connecting shaft 32 to rotate forward. Connecting shaft 32 drives rotating block 30 to rotate forward. Rotating block 30 drives rotating rod 27 to rotate forward. Rotating rod 27 drives receiving plate 26 and baffle 29 to rotate forward. When baffle 29 contacts the edge of operating table 1, baffle 29 rotates outward, causing rotating rod 27 to rotate. Rotating rod 27 drives receiving plate 26 to rotate to a horizontal position. When it is determined that there are no defects on both sides of the grinding wheel, motor 2 (31) starts and drives connecting shaft 32 to rotate in the opposite direction. Connecting shaft 32 drives rotating block 30 to rotate in the opposite direction. Rotating block 30 drives rotating rod 27 to rotate in the opposite direction. Rotating rod 27 drives receiving plate 26 and baffle 29 to rotate in the opposite direction. When baffle 29 contacts the edge of operating table 1...The baffle 29 rotates outward, causing the rotating rod 27 to rotate. The rotating rod 27 then rotates the receiving plate 26 to a horizontal position. Then, the electromagnet 24 is energized, attracting the adjacent rotating arms 19 on both sides. The two rotating arms 19 separate, causing the two semi-annular bodies 21 to separate. At this point, the grinding wheel on the boss 22 falls onto the receiving plate 26. Then, the electromagnet 24 is de-energized, and the compression spring 23 pushes the rotating arms 19 apart, causing the two rotating arms 19 to come together. The two rotating arms 19 then cause the semi-annular bodies 21 to come together. When combined, motor 31 starts and drives connecting shaft 32 to rotate in the opposite direction to the previous rotation. Connecting shaft 32 drives rotating block 30 and rotating rod 27 to rotate. Rotating rod 27 drives receiving plate 26 and baffle 29 to rotate. When baffle 29 separates from the edge of operating table 1, under the action of torsion spring 28, baffle 29 rotates inward. Baffle 29 drives rotating rod 27 to rotate, and rotating rod 27 drives receiving plate 26 to rotate to an inclined state. The grinding wheel slides off receiving plate 26, thereby achieving the screening and classification of qualified and unqualified grinding wheels.
[0030] Repeat the above operations to complete the visual inspection of all grinding wheels in the two placement cylinders 7 and the screening and classification of qualified and unqualified products.
[0031] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
