The invention relates to a multi-view capsule defect detection device facing an annular light source, which belongs to the technical field of capsule detection and comprises a box body, a feeding unit, a conveying unit, a roller rotating unit, a visual detection unit, a discharging unit and a central control unit. According to the detection device, to-be-detected capsules are conveyed into the box body through the feeding pipeline of the feeding unit, the to-be-detected capsules on the capsule conveying guide rail are conveyed to a detection position through the conveying unit, and the central control unit controls the visual detection unit to detect the to-be-detected capsules on the roller which continuously rolls; when the visual detection unit completes the detection of the to-be-detected capsules, the central control unit controls the next batch of to-be-detected capsules to move to the detection position in the same manner, and under the pushing of the next batch of to-be-detected capsules, the detected capsules enter a discharging pipeline of the discharging unit through a conical hole in the right side of the roller; therefore, the conveying of the detected capsules is completed, and the detection process of the to-be-detected capsules is achieved.
Description
technical field [0001] The invention relates to capsule defect detection, in particular to a multi-view capsule defect detection device facing an annular light source. Background technique [0002] Capsules have the function of protecting the effective drug ingredients inside, avoiding drug damage to the digestive organs and respiratory tract, and being convenient and easy to use. The defects of the capsules are detected during the manufacturing process, and the defective capsules are removed and collected to ensure the shipment quality of the capsules. is of great significance. [0003] At present, in order to ensure the all-round detection of capsules, it is mainly to place the capsules in a transparent pipe or a transparent groove to take 360-degree photographic inspections of the capsules through the visual detection unit. In the current detection method, when the light source is supplementing light, the reflection caused by the dirt on the transparent pipe or transpare...
