Description

Technical Field

[0001] This utility model relates to the field of automatic drug identification technology, and in particular to a multi-dimensional identification and dispensing device for drug management. Background Technology

[0002] With the development of automated drug management technology, intelligent drug dispensing equipment has been widely used in hospital pharmacies, retail pharmacies, and emergency scenarios. However, existing equipment still has many problems in actual use, especially in terms of the comprehensiveness of drug identification and the acquisition of traceability information, making it difficult to meet the needs of efficient and accurate drug management. Current automated drug dispensing systems usually rely on a single identification method (such as image recognition, radio frequency identification, or barcode scanning), which cannot read information from all sides of the medicine box. Especially when the drug traceability code is located on a non-visible surface such as the side or bottom of the medicine box, identification failure is very likely to occur. In addition, the non-fixed position of the medicine box in the storage compartment makes it difficult for the identification device to reliably capture key information, affecting the accuracy of drug verification and operational efficiency.

[0003] A search revealed a device and method for automatically identifying drug traceability codes, with publication number CN119558877B, published on June 24, 2025. This patent proposes separating and transporting drug boxes to a scanning channel via a climbing assembly line, and using scanning devices arranged in multiple directions to automatically identify the traceability codes on the drug boxes in any direction. This solution achieves continuous and automated scanning, improving identification efficiency. However, it is mainly applied to assembly line-style outbound scenarios, relying on external conveyor structures and cannot be integrated into enclosed intelligent medicine cabinets. Furthermore, the device only focuses on the physical reading of the traceability code, without combining multi-dimensional features such as drug appearance, text, and color for comprehensive judgment, lacking the ability to verify the composite nature and status of the drug. Even when the drug box is tilted, obscured, or the QR code is damaged, there is still a risk of misidentification or missed identification, making it difficult to meet the dual verification requirements of high-security scenarios.

[0004] Existing drug identification technologies either focus on image algorithm optimization while neglecting hardware collaboration, or prioritize scanning efficiency in linear delivery scenarios, failing to effectively address the blind spot problem caused by the uncertain posture of medicine boxes in enclosed medicine cabinet environments. Therefore, it is necessary to design a multi-dimensional identification and dispensing device for drug management to solve the above problems. Utility Model Content

[0016] Reference Figures 1 to 2 A multi-dimensional identification and dispensing device for drug management includes a dispensing buffer 1 for storing identified medicine boxes; a mounting base 2 disposed on one side of the dispensing buffer 1; a glass platform 3 disposed on the mounting base 2 for supporting the medicine boxes to be identified; a lower verification and traceability camera 6 disposed on the mounting base 2 and located below the glass platform 3; a pushing module 4 disposed on the mounting base 2; a pushing bracket fixed on the mounting base for supporting the pushing module; an upper verification and traceability camera 7 mounted on the pushing module 4 via the bracket; and a rotating identification module 5 disposed corresponding to the pushing module for grasping the medicine box and identifying its four sides.

[0017] The mounting base 2 is fixed to one side of the device, and a glass platform 3 is set on its top. The glass platform 3 is made of high-strength transparent material, and light sources are evenly distributed at the bottom to enhance the imaging effect. A verification and traceability camera 6 is set below the glass platform 3. The camera is fixed to the mounting base 2 with bolts and is kept at a certain distance from the glass platform 3 to facilitate the collection of information from the bottom of the medicine box.

[0018] A pushing module 4 is provided on one side of the glass platform 3. The pushing module 4 includes a linear guide rail 41, a slider 42, a pushing plate 43, and a drive motor. The linear guide rail 41 is fixed to the mounting base 2 by bolts. The slider 42 is connected to the linear guide rail 41 by a threaded connection. The drive motor drives the slider to move along the linear guide rail through a synchronous belt, thereby realizing the precise pushing of the medicine box.

[0019] The upper verification and traceability camera 7 is mounted on the push module 4 via a bracket. The camera is connected to the push module 4 via an adjustable bracket. By adjusting the angle and height, the upper verification and traceability camera 7 can adapt to medicine boxes of different sizes.

[0020] The rotating identification module 5 is located on one side of the pushing module 4. The rotating identification module 5 includes a horizontal driving module 8, a vertical driving module 9 driven by the horizontal driving module 8, a rotating gripping module 10 driven by the vertical driving module 9, and a four-sided verification and traceability camera 11 used in conjunction with the rotating gripping module 10 for identification. The horizontal driving module 8 is bolted to the drug dispensing buffer hopper 1 and contains a stepper motor as a drive source. The stepper motor drives the vertical driving module 9 to move horizontally via a lead screw transmission mechanism or a pulley assembly. The vertical driving module 9 is also driven by a stepper motor, which drives the rotating gripping module 10 to move vertically up and down via a lead screw transmission mechanism or a pulley assembly. The rotary gripping module 10 includes a rotary cylinder 101 and a material-picking suction head 102. The rotary cylinder 101 is fixed to the longitudinal drive module 9 by bolts, and its output shaft is connected to the material-picking suction head 102 via a coupling. A vacuum suction cup is provided at the bottom of the material-picking suction head 102 for stable suction of the medicine box. A four-sided verification and traceability camera 11 is provided on one side of the rotary gripping module 10. The camera is fixed to the bracket of the rotary gripping module 10 by bolts, and a ring light source is provided at the front end of the detection port to provide uniform illumination.

[0021] To ensure the stability of the equipment operation, the rotary gripping module 10 also includes a limit sensor. The limit sensor is fixed to the bracket of the rotary gripping module 10 by bolts and is used to detect whether the medicine box is correctly picked up and whether the rotation angle is in place.

[0022] When the medicine box is placed on the glass platform 3, the lower verification traceability camera 6 first collects information from the bottom surface of the medicine box. If a traceability code is present on the bottom surface, identification is completed directly. Then, the push module 4 moves the slider along the linear guide rail, pushing the medicine box into the dispensing buffer hopper 1. If the lower verification traceability camera 6 does not detect a traceability code, the upper verification traceability camera 7 is activated to collect information from the top surface of the medicine box. If a traceability code is present on the top surface, identification is completed, and the push module 4 pushes the medicine box into the dispensing buffer hopper 1. If neither the upper nor lower verification traceability camera detects a traceability code, the rotating gripping module 10 is moved onto the glass platform 3 through the cooperation of the horizontal drive module 8 and the vertical drive module 9. The material suction head picks up the medicine box through the vacuum suction cup and moves it to the front end of the detection port of the four-sided verification traceability camera 11. Subsequently, the rotating cylinder drives the medicine box to rotate 90° each time, and the four-sided verification and traceability camera 11 checks the four sides of the medicine box until the traceability code is recognized. After the adsorption is canceled, the medicine box falls into the medicine dispensing buffer hopper 1.

[0023] In this implementation case, when the medicine box is placed on the glass platform 3, the bottom verification camera 6 first collects information from its bottom surface. The glass platform 3 is made of high-strength transparent material, and light sources are evenly distributed on its bottom. The brightness of the light sources is adjusted by a controller to ensure clear and stable imaging. When the bottom verification camera 6 detects a traceability code on the bottom surface, the controller records the information and starts the drive motor in the push module 4. The drive motor drives the slider to move along the linear guide rail via a synchronous belt, thereby accurately pushing the medicine box into the dispensing buffer hopper 1 to complete the operation. If the lower verification traceability camera 6 fails to detect the traceability code, the upper verification traceability camera 7 will collect information from the top surface of the medicine box. The upper verification traceability camera 7 is mounted on the push module 4 via an adjustable bracket. If the top surface has a traceability code, the push module 4 will push the medicine box into the dispensing buffer hopper 1. If neither the top nor bottom verification cameras detect the traceability code, the process enters the workflow of the rotating recognition module 5. At this point, the horizontal drive module 8 drives the vertical drive module 9 to move horizontally, while the vertical drive module 9 drives the rotating gripping module 10 to move vertically above the glass platform 3. Then, the vacuum suction cup at the bottom of the suction head picks up the medicine box, and the rotating gripping module 10 moves the medicine box to the front of the detection port of the four-sided verification traceability camera 11. The rotating cylinder drives the medicine box to rotate 90° each time, and the four-sided verification traceability camera 11 collects information from each of the four sides of the medicine box until the traceability code is detected. Once the four-sided verification camera 11 successfully identifies the traceability code, the rotating gripping module 10 cancels the vacuum adsorption, and the medicine box falls into the dispensing buffer hopper 1, completing the operation. During this process, the stability of the rotating gripping module 10 and the high-precision detection capability of the four-sided verification camera 11 effectively solve the problem of blind spots caused by the uncertain posture of the medicine box. Furthermore, through multi-dimensional feature verification, combined with information such as the appearance, text, and color of the medicine box, the composite verification capability of drug type and status is further improved, meeting the dual verification requirements in high-security scenarios.

[0024] The advantages of this utility model are that, by setting up a lower verification and traceability camera, an upper verification and traceability camera, and a rotating recognition module, this technical solution achieves comprehensive information collection from all six sides of the medicine box, solving the problem of blind spots in recognition caused by the uncertain posture of the medicine box in the prior art. By combining the rotating gripping module with the four-sided verification and traceability camera, accurate collection of information from the side of the medicine box is achieved. Even if the medicine box is tilted or the QR code is damaged, the recognition success rate can be improved through multiple rotations and inspections.

[0025] 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.
