[0002] In the modern pharmaceutical industry, the production, packaging, and distribution of tablets are crucial. With the continuous increase in the types of drugs and the expansion of market demand, the need for efficient and accurate tablet sorting devices is becoming increasingly prominent.

[0003] Currently, some tablet sorting devices use machine vision technology to detect defects on the tablets. However, since the tablets are transported with one side facing up and the other side in contact with the conveyor line, the machine vision cannot detect the other side of the tablet, leading to detection errors and reducing the quality of tablet production. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example: This example provides a tablet sorting device, see [link to example]. Figure 1-4 Specifically, it includes a fixed platform 1, on which a rotating shaft 11 is rotatably provided in the middle of its upper surface. The rotating shaft 11 is cylindrical and is vertically installed on the fixed platform 1.

[0027] A disc-shaped transport tray 12 is rotatably mounted on the upper end of a rotating shaft 11. Multiple placement slots 13 for placing tablets are opened in a ring around its edge. The placement slots 13 are symmetrically arranged at the center of the rotating shaft 11 and the transport tray 12. The tablets are attached to the inner wall of the placement slots 13 and are in the shape of discs.

[0028] The face-changing component 4 is set on the fixed platform 1. By rotating the shaft 11, the tablets placed in the placement slot 13 can be changed from a lying state to an upright state. The face-changing component 4 is located below the transport tray 12. When the shaft 11 drives the transport tray 12 to rotate, the transport tray 12 drives the tablets to the position of the face-changing component 4. The face-changing component 4 changes the tablets in the placement slot 13 from a flat position to a vertical position in the placement slot 13, which is convenient for inspecting both sides of the tablets.

[0029] Two inspection cameras 14 are respectively set on the fixed platform 1. One inspection camera 14 is configured to inspect one side of the tablet from above, and the other inspection camera 14 is configured to inspect the other side of the tablet from the side. The inspection cameras 14 inspect the tablets to observe whether there are any defects on the tablets. The first inspection camera 14 is used to inspect the tablets laid flat in the placement slot 13. After inspection, the tablets are driven by the transport tray 12 to rotate to the position of the face-changing component 4. The face-changing component 4 turns the tablets into an upright state. The upright tablets are then moved to the second inspection camera 14 to inspect the bottom surface of the tablets, so as to achieve uniform inspection of the tablets.

[0030] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a fixed plate 2 is fixedly provided on the upper surface of the fixed platform 1. The upper surface of the fixed plate 2 is in contact with the lower surface of the conveying plate 12. A feeding groove 21 is provided on the edge of the fixed plate 2. The feeding groove 21 has the same shape as the placement groove 13. A collection box 22 is provided on the upper surface of the fixed platform 1. The opening of the collection box 22 is directly opposite the feeding groove 21.

[0031] The conveyor tray 12 is used to limit the tablets in the placement slot 13 to prevent them from falling out. After both sides of the tablet are detected, the tablet in the placement slot 13 is moved to the feeding slot 21 on the conveyor tray 12. The tablet falls from the feeding slot 21 into the collection box 22, thus realizing the feeding and collection of the tablets.

[0032] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a feeding pipe 3 is fixedly installed on the fixed platform 1. The lower end of the feeding pipe 3 is attached to the edge of the upper surface of the conveying tray 12, and the inner wall of the feeding pipe 3 is the same as the diameter of the tablet.

[0033] The tablets are loaded into the feeding tube 3 and stacked vertically inside the feeding tube 3. Since the feeding tube 3 is attached to the upper surface of the conveying tray 12, when the lower end of the feeding tube 3 is aligned with the placement groove 13, the tablet at the bottom of the feeding tube 3 will fall into the placement groove 13. Since the placement groove 13 is at the same height as the tablets, the tablets at the top will not enter the placement groove 13, thus realizing the feeding of tablets.

[0034] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the face-changing assembly 4 includes a fixed column 41 and a drive disk 42. The lower end of the fixed column 41 is fixedly connected to the fixed platform 1, and the middle part of the drive disk 42 is fixedly connected to the rotating shaft 11. A connecting rod 43 is slidably provided in the groove of the fixed column 41. A top rod 44 is fixedly provided at one end of the connecting rod 43, and the other end of the connecting rod 43 is located above the drive disk 42. A spring 45 is vertically provided in the groove of the fixed column 41.

[0035] The rotation of the shaft 11 will drive the transport disk 12 and the drive disk 42 to rotate synchronously. When the protrusion on the drive disk 42 contacts the connecting rod 43, the connecting rod 43 moves upward along the groove of the fixed column 41. The connecting rod 43 drives the top rod 44 to move synchronously. The top rod 44 enters the placement groove 13 from the edge of the fixed disk 2, lifts the tablet in the placement groove 13 from the edge, and makes the tablet stand upright, so that the detection camera 14 can detect both sides of the tablet.

[0036] In the specific implementation process, such as Figure 2 and Figure 3As shown, a motor 5 is fixedly mounted on the upper surface of the fixed platform 1, a first turntable 51 is fixedly mounted on the output end of the motor 5, a second turntable 52 is fixedly mounted on the rotating shaft 11, two round rods are arranged laterally on the side wall of the first turntable 51, and multiple round rods are arranged in a ring on the edge of the upper surface of the second turntable 52.

[0037] The motor 5 drives the first turntable 51 to rotate, and the two round rods of the first turntable 51 will contact the round rods on the second turntable 52, causing the second turntable 52 to rotate. The second turntable 52 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the transport tray 12 to rotate. The first turntable 51 and the second turntable 52 make the transport tray 12 rotate intermittently, which makes it convenient for the face-changing assembly 4 to turn the tablets into upright ones, and also makes it convenient for the detection camera 14 to perform detection.

[0038] In the specific implementation process, such as Figure 1 and Figure 4 As shown, a stop bar 6 is fixedly provided on the upper surface of the fixed platform 1, and the lower surface of the stop bar 6 is in contact with the upper surface of the fixed platform 1; the stop bar 6 is used to block the tablets in the vertical state so that when the tablets are upright, they will not become flat again.

[0039] In the specific implementation process, such as Figure 3 and Figure 4 As shown, a rectangular block 7 is fixedly provided in the middle of the connecting rod 43. The rectangular block 7 is attached to the inner wall of the fixed column 41, and the upper end of the spring 45 is fixedly connected to the rectangular block 7. The rectangular block 7 is attached to the inner wall of the fixed column 41 to limit the movement of the connecting rod 43, so that the movement of the top rod 44 is more stable.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
