[0051] The driving assembly 30 is arranged on the frame, the driving assembly 30 has a plurality of driving ends, and all the driving ends of the driving assembly 30 are uniformly distributed along the length direction of the support plate 10 and are all located above the support plate 10. The driving ends of the driving assembly 30 are used for driving the medicine particles 50 to move on the support plate 10, and the distance of each movement is greater than or equal to the diameter of one medicine particle 50.

[0052] The medicine pushing assembly 40 is arranged on the frame, and the medicine pushing assembly 40 is located at the end of the support plate 10, and the driving end of the medicine pushing assembly 40 is located at the side of the support plate 10.

[0053] In the working process, the medicine particles 50 are sequentially conveyed one by one on the support plate 10 through the conveying belt, and the medicine particles 50 are driven one by one to the comparison area 11 by the driving assembly 30 on the support plate 10, the medicine particles 50 in the comparison area 11 are photographed by the camera 20, and the photographed pictures are transmitted to the computer for image processing, and through image analysis and processing technology, whether the outer surface of the medicine particle 50 has defects is judged, if there are defects, the medicine particle 50 is pushed off from the support plate 10 by the medicine pushing assembly 40 when passing through the end of the support plate 10, so that the unqualified medicine particle 50 is removed.

[0054] In one specific embodiment,

[0055] The support plate 10 is provided with two guide plates 12, and the two guide plates 12 are close to the front end of the support plate 10, one end of the two guide plates 12 is close to the comparison area 11, the distance between the two guide plates 12 at this end is slightly greater than the diameter of the medicine particle 50, and the other end of the two guide plates 12 is close to the front end of the support plate 10 and is in a diverging shape.

[0056] Through the technical scheme, the two guide plates 12 arranged on the support plate 10 can guide the medicine particles 50 to the correct position of the comparison area 11, so as to facilitate the photographing of the camera 20.

[0057] In another specific embodiment,

[0060] In the working process, when the medicine pellet 50 is about to completely enter the comparison area 11, the fourth cylinder 15 drives the lifting plate 14 to rise, and plays a blocking role on the medicine pellet 50, and when the driving assembly 30 stops moving, the lifting plate 14 is driven to descend, so that the top of the lifting plate 14 is below the plate surface of the support plate 10.

[0061] In another specific embodiment,

[0062] The comparison area 11 is provided with two annular lines, which are an inner warning line and an outer warning line. By setting the guide plate 12 and the lifting plate 14 in the comparison area 11, the medicine pellet 50 can be driven into a fixed area, and the inner warning line and the outer warning line are arranged in the area, so that when the camera 20 takes a picture, the inner warning line and the outer warning line can be taken together, so that when the image information is compared, whether the diameter of the medicine pellet 50 is within the required range can be judged by judging the position of the outer contour of the medicine pellet 50.

[0063] In another specific embodiment,

[0064] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the driving assembly 30 includes a support frame 31, a push block 32, a first cylinder 33, a support seat 34, a rotating shaft 35, a gear 36, a rack 37 and a second cylinder 38. The support frame 31 is slidingly arranged on the rack, the sliding direction of the support frame 31 is parallel to the length direction of the support plate 10, and the support frame 31 is located above the support plate 10.
