[0057] The primary photographic inspection mechanism 3 and the secondary photographic inspection mechanism 5 perform appearance inspection on the front and back of the drug; the primary photographic inspection mechanism 3 and the secondary photographic inspection mechanism 5 have the same structure, and this embodiment only describes the primary photographic inspection mechanism 3 in detail;
[0058] The primary photographic inspection mechanism 3 includes a support assembly, a high-resolution camera 35, and a light source assembly. The support assembly includes a Y-shaped top plate 31, three side light source mounting plates 32 connected to the bottom surface of the top plate 31, two inspection mechanism mounting frames 33 connected to the sides of the top plate 31, and a camera mounting bracket 34 mounted on the top of the top plate 31. The edge of the top plate 31 is provided with multiple heat dissipation holes, and a through hole is formed in its center, which serves as the inspection channel for the high-resolution camera to inspect materials. Backlight mounting holes are formed on the side light source mounting plates 32. The inspection mechanism mounting frames 33 are L-shaped, enabling the photographic inspection mechanism to be installed in the upper cabinet. The high-resolution camera 35 is connected to the camera mounting bracket 34, and its lens faces the through hole in the center of the top plate 31.

A through hole is formed in the middle of the open backlight 37, and the position of the through hole corresponds to the through hole in the top plate 31.
[0059] The photographic inspection agency uses advanced high-pixel cameras and large-diameter light sources. The innovative combination of light sources uses two different light sources to expose and take pictures separately. Three sets of backlight spotlights are arranged in a triangular layout and use multiple colors of light sources. One set of open-aperture backlight light sources is located at the top to illuminate different defects in the inspected drugs, enabling the vision system to completely and clearly detect different defects in the drugs. The backlight spotlight utilizes high-brightness LEDs and a unique illumination structure. The light emitted by the LEDs is diffused by a special diffuse reflection material within the spherical surface, creating a bright and uniform diffused light. The perforated backlight source features an integrating hemispherical inner wall that uniformly reflects light emitted from the bottom 360 degrees, resulting in highly uniform illumination across the entire image. This is suitable for detecting curved, uneven, and arc-shaped surfaces. For pharmaceutical blister packs with varying numbers of blister packs, capsules, or tablets of different colors, the spherical integrating light source can illuminate these uneven products, accurately reflecting their condition. The low-angle ring light features a high-density LED array with high brightness. The toothed surface design improves heat dissipation efficiency, and the low-angle illumination emphasizes edge lighting. Multi-angle illumination highlights the three-dimensional information of objects and solves the problem of shadows caused by angled illumination. Main applications include: detection of foreign matter contamination in pharmaceuticals; various edge extraction and detection techniques; various character recognition and edge detection; and detection of markings, damage, and dirt on metal surfaces.
[0060] The primary rejection mechanism 4 and the secondary rejection mechanism 6 are used to reject drugs whose front and back appearances are unqualified, respectively. The primary rejection mechanism 4 and the secondary rejection mechanism 6 have the same structure. This embodiment only describes the primary rejection mechanism 4 in detail.
[0061] The primary rejection mechanism 4 includes a connecting plate 41, a mounting plate 44, a vacuum generator 42, a rejection suction tube 43, and a suction inlet adjustment mechanism.
[0062] The connecting plate 41 is L-shaped, with its short wall fixedly connected to the mounting bracket plate 26 of the conveying mechanism 2, and its long wall positioned above the mounting plate 44. The long wall of the connecting plate 41 is connected to the top of the mounting plate 44 via a height adjustment mechanism 45. The height adjustment mechanism 45 includes a screw and a rotating disk fixed to the top of the screw. The lower end of the screw is a smooth rod, which is inserted into the top surface of the mounting plate 44, and a rotating bearing is provided between the two. The upper end of the screw passes through the connecting plate 41, and the two are threaded together. By rotating the rotating disk, the screw is driven to rotate, and the rotation of the screw drives the connecting plate 41 to move up and down. The height adjustment mechanism 45 also includes two sets of guide rods, which are located on both sides of the screw. One end of the guide rod passes through the long wall of the connecting plate 41, and the other end is fixed to the mounting plate 44. A limiting mechanism is provided at the top of the guide rod, and the guide rod is a telescopic rod to ensure the stability of the height adjustment mechanism when adjusting the height of the connecting plate 41.
[0063] The mounting plate 44 has an inverted L-shaped structure, and its short wall is connected to the long wall of the connecting plate 41; the vacuum generator 42 and the removal suction tube 43 are respectively fixed to both sides of the long wall of the mounting plate 44; the vacuum port end of the vacuum generator 42 is connected to the removal suction tube 43.
[0064] The inlet adjustment mechanism includes a pressure plate 46, a pressure plate height adjustment slider 47, and a pressure plate mounting bracket 48. The pressure plate 46 is positioned below the inlet of the rejection tube 43, and both ends of the pressure plate 46 are connected to the pressure plate mounting bracket 48 via the pressure plate height adjustment slider 47. The pressure plate mounting bracket 48 is connected to a mounting plate 44. An elongated hole is formed on the pressure plate height adjustment slider 47. By adjusting the connection position, the distance between the pressure plate 46 and the inlet of the rejection tube 43 can be changed, thereby adjusting the size and airflow of the inlet to accommodate tablets of different sizes.
[0065] The suction end of the rejection pipe 43 is located above the conveyor belt of the input component 21, and the outlet end is connected to the rejection waste collector.
[0066] The primary rejection mechanism 4 and the secondary rejection mechanism 6 are respectively installed above the conveyor belt of the input component 21 and the conveyor belt of the flipping output component 22. Their positions and heights are adjustable. Utilizing a vacuum principle, a vacuum generator empties the air from the rejection pipe 43, creating a vacuum environment that allows the tablets to be sucked in and discharged. The rejection mechanism operates on a vacuum principle; upon receiving a rejection command, the corresponding rejection channel opens. The vacuum generator creates a vacuum in the rejection channel, causing the tablets to be sucked out and moved to the rejection collector. The rejection system can be adjusted vertically according to the tablet thickness. The system employs a modular design, allowing for quick switching between different rejection systems for different tablets. It innovatively uses a double-row rejection port, with each port having an overlapping portion to prevent missed or insufficient rejection.
[0067] The pharmaceutical appearance inspection equipment also includes an industrial control computer (ICC), which is electrically connected to all mechanisms to achieve intelligent electronic control. The ICC uses the latest Intel processor and Z690 chipset, and the hardware is configured according to the inspection requirements to ensure performance while optimizing the configuration.
[0068] The drug appearance inspection equipment also includes a touch screen 9, which is a 21.5-inch industrial vertical screen display that is aesthetically pleasing and facilitates better operation and data monitoring for the operator.
[0069] The working principle of this utility model:
[0070] This utility model tablet drug appearance inspection device adopts the machine vision inspection principle and high-speed image processing technology to detect defects such as black spots, bubbles, and splits on capsules, and black spots, cracks, and missing tablets on tablets. It has a fast detection speed, high detection accuracy, and is simple and easy to use.
[0071] The material is fed by a vibrating table to ensure a continuous supply. The material enters the vibrating feeding plate 71 of the vibrating feeding mechanism 7 through the hopper 8. Under the vibration of the vibrating table assembly 72, the material reaches the conveyor belt of the input assembly 21 from the vibrating feeding plate 71. The material is spread flat on the conveyor belt of the input assembly 21 by the action of the brush roller 24. The material is conveyed at a uniform speed on the conveyor belt of the input assembly 21. After passing through the first-level photographic inspection point, the upper part of the material is photographed and inspected. The material that has completed the inspection is wrapped by the two-stage conveyor belt at the overlap of the conveyor belt of the input assembly 21 and the conveyor belt of the flipping output assembly 22 to complete the flipping of the material. The material leaves the conveyor belt of the input assembly 21 and is transferred to the conveyor belt of the flipping output assembly 22. The material is conveyed at a uniform speed on the conveyor belt of the flipping output assembly 22. After passing through the second-level photographic inspection point, the other side of the material is photographed and inspected. The inspection machine makes a judgment based on the comparison of the template and the surface information of the material, and gives and executes the rejection action. Unqualified materials are removed, while qualified materials pass through the testing machine and reach the discharge port, ensuring the quality of materials before they leave the factory.
[0072] This invention is applicable to tablets of various shapes with a diameter not exceeding 40mm and a thickness not exceeding 15mm produced by manufacturing plants.
