Description

Technical Field

[0001] This invention relates to the field of drug verification, and in particular to a drug verification device and its control system for an automatic drug vending machine. Background Technology

[0002] Automated medicine vending machines are intelligent devices that integrate medicine storage, sales, and management. They support 24 / 7 uninterrupted service and allow users to select, pay for, and collect medicines via touchscreen or mobile phone. Their core advantages include small footprint, convenient payment, and round-the-clock response to urgent medication needs.

[0003] When dispensing medicine, automatic medicine vending machines cannot guarantee the posture of the medicine boxes, which may affect the dispensing process if the medicine boxes are in different postures. In addition, they lack a structure to check the medicine boxes, so they cannot guarantee that the medicine box being dispensed is consistent with the one purchased by the customer.

[0004] Therefore, it is necessary to propose a drug verification device and its control system for an automatic drug vending machine to solve the above problems. Summary of the Invention

A drive component is installed at the bottom of the verification chamber. Moisture-proof fans are symmetrically installed on both sides of the bottom of the verification chamber.

[0007] Preferably, the top of the first push plate is rotatably connected to a roller, the side of the first push plate is attached to the bottom of the side of the frame, and the outer wall of the shelf is equipped with a first hydraulic push rod, which is connected to the first push plate.

[0008] Preferably, retractable blocks are symmetrically installed on both sides of the first push plate, a fixed rod is installed in the inner cavity of the shelf, a spring is wound around the outer wall of the fixed rod, one end of the spring is connected to the retractable block, the other end of the spring is installed in the inner cavity of the shelf, and the retractable block is movably connected in the inner cavity of the shelf and sleeved on the outer wall of the fixed rod.

[0009] Preferably, there are two cameras: one camera is located at the top of the second conveyor track, and the other camera is located in the center of the top of the verification chamber.

[0010] Preferably, a first lead screw is rotatably connected to the inner cavity of the wall, the first lead screw is driven by a motor installed in the wall, and one end of the adjusting plate is movably connected to the inner cavity of the wall and threadedly connected to the first lead screw.

[0011] Preferably, a glass plate is installed in the center of the conveying assembly, a guide post is installed in the inner cavity at one top end of the conveying assembly, a second lead screw is installed in the inner cavity at the other top end of the conveying assembly, and the side of the second push plate near the roller label printer is inclined.

[0012] Preferably, both ends of the bottom of the second push plate are movably connected to the inner cavities at both ends of the conveying assembly. One end of the bottom of the second push plate is sleeved on the outer wall of the guide post, and the other end of the bottom of the second push plate is threaded to the outer wall of the second lead screw. A servo motor is installed on the side of the conveying assembly, and the servo motor is connected to the second lead screw through a first rotating shaft.

[0013] Preferably, guide rods are symmetrically installed in the inner cavities on both sides of the top of the verification chamber, and the bottom sides of the dustproof plate are symmetrically and movably connected to the inner cavities on both sides of the top of the verification chamber and sleeved on the outside of the guide rods. A second hydraulic push rod is installed on the outer wall of the wall, and the second hydraulic push rod is connected to the dustproof plate.

[0014] Preferably, a belt is installed in the inner cavity of the drive assembly, and pulleys are installed on both sides of the inner cavity of the belt. The pulleys are used to drive the dehumidifying fan. A drive motor is installed at the bottom of the drive assembly, and the drive motor is connected to one of the pulleys through a second rotating shaft.

[0015] A control system for a drug verification device in an automated drug vending machine includes: The order parsing and task allocation module is used to receive order data from the user interface of the automatic medicine vending machine and the pharmacy management system, and perform order validity verification: check whether the drug ID exists, whether the quantity exceeds the inventory, and whether the drug is within the expiration date. If the verification fails, a prompt is immediately sent to the user interface and recorded; if the verification passes, a task instruction package is generated, which includes the target frame ID, drug posture correction parameters, and verification code. The multi-dimensional drug verification logic module uses a left-side camera for visual verification. It receives pre-processed images from the left camera and extracts features from the drug box using an AI image recognition algorithm based on a convolutional neural network. These features are then compared with standard features in the drug database. If the similarity is ≥98% and the identified drug ID matches the order requirements, the first step is considered successful. If the similarity is 85%-97%, the camera parameters are adjusted to re-encode the image and compare it again. If the similarity is <85%, the visual verification is deemed inconsistent, and an anomaly is marked. The code scanning verification process involves receiving the drug traceability code and order association code sent by the scanner and comparing them with the code to be verified in the task instruction package. If both codes match, the scan is considered successful; otherwise, if only one code matches or neither code matches, the scan is considered abnormal and the code value difference is recorded. The camera on the right performs a secondary visual verification, receiving images of the barcode on the top of the medicine box and the label on the bottom, extracting the code information using OCR recognition technology, and comparing it again with the code to be verified; at the same time, an edge detection algorithm is used to check whether the medicine box is damaged, and if it is damaged, the integrity of the medicine is determined to be abnormal. The real-time inventory update and early warning module immediately reduces the corresponding drug inventory by one and updates the inventory status after the medicine box is shipped normally: inventory ≥ 10 is marked as sufficient, 3 ≤ inventory < 10 is marked as tight, inventory < 3 is marked as scarce, and if the inventory is 0, the module removes the drug from the list of available drugs.
