[0024] In the visual detection process, the medicine bags need to be detected one by one, and the medicine bags need to be placed transversely, so that the maximum field of view can be used for detection, therefore Figure 2 As shown in the drawings, the bottom of the medicine bin 3 is connected with a medicine outlet pipeline 31, the medicine outlet pipeline 31 only accommodates a single medicine bag to fall transversely, and a gap is formed between the pipe opening of the medicine outlet pipeline 31 and the belt surface of the medicine bag conveying belt 2, the gap can only allow a single transversely placed medicine bag to pass through.

[0025] As shown in the drawings, Figure 2 and Figure 3 The belt surface of the medicine bag conveying belt 2 adopts a strip structure, the belt surface of the medicine bag conveying belt 2 comprises a plurality of arranged and installed strip boards 21, a groove 22 is formed in each strip board 21, the groove 22 can accommodate a single medicine bag to be placed transversely, the medicine bag falls into the groove 22 after falling, and then the linear circulation movement effect of the medicine bag is formed through the movement of the strip board 21.

[0026] In the medicine bag feeding process, there may be a case that the medicine bag cannot fall into the groove 22, at this time, the medicine bag will be on the plane of the strip board 21, which will affect the subsequent visual detection, therefore, it is necessary to remove it before visual detection, therefore, as Figure 3As shown, this utility model designs a surface cleaning device 4 to solve the above problems. The surface cleaning device 4 includes a first blowing box 41 and a recycling trough 42. The first blowing box 41 and the recycling trough 42 are respectively installed on both sides of the drug bag conveyor belt 2. When the drug bag conveyor belt 2 passes through the surface cleaning device 4, the first blowing box 41 can form a blowing effect in the direction of the recycling trough 42. The wind force is relatively small. If the drug bag is in the groove 22, it will not be blown. If the drug bag is on the plane of the slat 21, the drug bag has no resistance effect and the drug bag will be blown into the recycling trough 42 and concentrated.

[0027] like Figure 4 As shown, the visual inspection device 5 includes a camera bracket 51 and a camera 52.

Figure 1 As shown, the visual inspection device 5 also includes a contact plate 54, which is located directly below the camera 52. The contact plate 54 is installed below the strip 21 of the drug bag conveyor belt 2. The contact plate 54 does not affect the transmission of the strip 21. When the drug bag falls into the groove 22, the bottom of the drug bag extends beyond the lower plane of the strip 21. When the strip 21 passes the contact plate 54, the bottom of the drug bag contacts the contact plate 54. Under the action of friction, the drug bag rotates. The drug bag passes the position of the camera 52 in a rotating state. In this way, the camera 52 can fully capture the appearance image of the drug bag, ensuring the accuracy of the appearance inspection. The length of the contact plate 54 covers the travel distance of the drug bag as it passes the camera 52, thus ensuring that the drug bag is in a rotating state when it passes the camera 52.
