[0049] The feeding mechanism conveys the material to be inspected to the material transmission device, which drives the material to be inspected to move along the transmission direction and makes the material to be inspected rotate, and sequentially collects and scans the material to be inspected through the side image acquisition device 105, and the rejection device 106 rejects unqualified material to be inspected, and the recovery device 107 collects qualified material to be inspected.

[0050] refer to Figure 1As shown, in this embodiment, the material to be inspected is a medicine, which can be a medicine with a cylindrical, elliptical or spherical structure, such as a capsule. In actual application, a feeding mechanism is used to transport the material to be inspected to a material transmission device, which drives the material to be inspected to rotate, and sequentially transports the material to the side image acquisition device 105 for acquisition and scanning. The rejection device 106 rejects unqualified materials to be inspected, and the recovery device 107 collects qualified materials to be inspected. The mechanism operation and control system is used to perform all-round detection of the side area of ​​the capsule, so as to solve the problems of poor compatibility of capsule medicine detection, difficulty in system debugging, incomplete detection and unsatisfactory detection functions, so as to help drug manufacturers accurately reject defective products and improve the quality of drugs.

[0051] refer to Figure 1 As shown, in this embodiment, the feeding mechanism includes a storage box 101 and a linear vibration mechanism 102. The material to be inspected is placed in the storage box 101, and then the linear vibration mechanism 102 disperses the material to be inspected and arranges it into columns. The linear vibration mechanism 102 is a linear vibration screen or a linear vibrator, which arranges the material to be inspected neatly. The material to be inspected can be arranged in order on the material transmission device, thereby improving the transportation efficiency of the material to be inspected.

[0052] refer to Figure 1 , 2 As shown, in this embodiment, the material conveying device includes a material height limiting mechanism 103 and a roller material conveying mechanism 104. The material to be inspected is sent out from the discharge end of the linear vibration mechanism 102, and then sent to the roller material conveying mechanism 104 after passing through the material height limiting mechanism 103. The roller material conveying mechanism 104 drives the material to be inspected to move along the conveying direction and causes the material to be inspected to rotate.

[0053] In actual application, a gap is left between the material height limiting mechanism 103 and the roller material transmission mechanism 104, through which the flatly placed material to be inspected can pass smoothly. The material height limiting mechanism 103 limits the position of the material to be inspected, ensuring that the material to be inspected is flatly placed on the roller material transmission mechanism 104. The roller material transmission mechanism 104 drives the material to be inspected to move toward the discharge end, and simultaneously drives the material to be inspected to rotate. The side image acquisition device 105 is used to perform all-round detection of the side of the material to be inspected. Specifically, the side image acquisition device 105 The linear module is driven by a linear module, which can be a screw motor module, a synchronous belt module or an oil cylinder. The linear module drives the side image acquisition device 105 to move synchronously with the material to be inspected.

During the process of the mobile driving mechanism 1 driving the material to be inspected to move along the transmission direction, the rotation driving mechanism 2 drives the material shaft 3 to rotate so that the material to be inspected rotates, thereby cleverly driving the material to be inspected to rotate during the transportation of the material to be inspected. An image acquisition device is set above the material to be inspected, and the material to be inspected can be sequentially conveyed to the points of the image acquisition device for acquisition and scanning, so as to realize the side all-round detection function, which is conducive to realizing online defect detection of the material to be inspected, improving production quality, and improving production efficiency.

Since the material shaft 3 is rotatably installed on the mounting seat 12, the self-rotation drive mechanism 2 is used to drive the material shaft 3 to rotate during the movement of the material shaft 3 and the mounting seat 12. The bottom of the material to be inspected is rubbed by the material shaft 3, thereby driving the material to be inspected to rotate, meeting the multi-angle detection requirements of the material to be inspected; when the material shaft 3 is driven by the self-rotation drive mechanism 2, it rotates accordingly, smoothly rubbing the material to be inspected to rotate, and cleverly controlling the rotation of the material to be inspected, realizing all-round detection of the side of the material to be inspected, and improving the detection accuracy of the material to be inspected.
