When the medicine is placed on the protective pad 11 in the placement groove 10, the baffle 8 is pulled open by the handle 9 to take the medicine out of the material taking port 7.
[0034] The implementation steps of this method are:
[0035] 1. Collect the appearance images of all drugs, and extract the features of the product images through the feature extractor. Since the Histograms of Oriented Gradient (HOG) algorithm has good adaptability to images with lighting changes and geometric deformations, it can adapt to a variety of scenes and conditions and shows good robustness in practical applications. While effectively capturing the local shape information in the image, it has high computational efficiency and is suitable for real-time image processing and machine vision applications. Therefore, we use the HOG algorithm to extract features, and establish a database by combining the feature extraction results with their corresponding storage location information and unit price. It can be expressed as:
[0036] Item A:{A,F(f1,f2,...f m ),L(l1,l2,...l n ),P}
[0037] Where F is the set of feature points extracted from the item, L is the storage location coordinates of the item, such as L (warehouse No. 1, shelf No. 2, floor 3, ...), P is the unit price of the drug, and the constructed database is stored in the computer.
[0038] 2. The image collector 6 obtains the appearance image of the purchased medicine, and the feature extractor uses the HOG algorithm to extract the feature information of the item and establish the feature point set F (f1, f2, ... f m ).
[0039] 3. The computer matches these feature points with the features stored in the database one by one and calculates the Euclidean distance of each pair of feature points.
[0040] 4. Result output: If the calculated Euclidean distance is less than the set threshold λ1, it is considered that the two feature points are matched successfully. If there are more than λ2 feature points in the feature point set of an item in the database that satisfy the Euclidean distance less than the threshold λ1, the computer will store the location information L(l1,l2,...l n ) and the purchase quantity N are transmitted to the medicine dispensing device, and the unit price information P and the total purchase price are displayed on the control panel 2.
[0041] The working principle and use process of the utility model include the following steps when in use:
[0042] 1. Image acquisition: The customer places the medicine to be purchased on the medicine display table 4. The sensor light 5 above will illuminate for 3 seconds when the medicine appears below. At the same time, the image collector 6 obtains the appearance image of the medicine. The image collector 6 is electrically connected to the feature extractor.
[0043] 2. Quantity confirmation: The customer enters the quantity of medicines to be purchased on the display screen of the control panel 2, and then clicks the confirmation button to complete the purchase quantity confirmation.
[0044] 3. Feature extraction: The feature extractor extracts features from the drug appearance image acquired by the image collector 6 , and transmits the extracted feature information to the processor in the control panel 2 .
[0045] 4. Feature matching: The processor uses a matching algorithm to match the features of the items to be stored with the features in the database one by one.
[0046] 5. Position output: When the number of successful matches is greater than the threshold, it is considered that the item to be stored successfully matches an item in the database, and the processor transmits the location coordinates and quantity corresponding to the medicine to the medicine dispensing device.
[0047] 6. Drug transportation: The drug picking device finds the drugs according to the location coordinates and quantity of the drugs, and the first motor 13 drives the first screw rod 14 to rotate. Under the limit guidance of the first guide rod 15, the mounting plate 16 drives the structure thereon and the mechanical clamp 22 to move up and down, so that the mechanical clamp 22 moves to a row corresponding to the drugs to be picked up, and the second motor 18 drives the second screw rod 19 to rotate. Under the limit guidance of the second guide rod 20, the moving block 21 drives the mechanical clamp 22 installed thereon to move left and right. After moving to the position, the electric telescopic rod 23 drives the mechanical clamp 22 to move back and forth to grab the drugs on the shelf 12. After picking up, the mechanical clamp 22 is driven to continue to move downward until the drugs picked up by the mechanical clamp 22 contact the protective pad 11 in the placement slot 10, and the drugs are released to complete one drug picking. According to the required number of drugs to be picked up, the next drug picking can be carried out.
[0048] 7. Complete the purchase: The processor transmits the total price of the purchased medicine to the barcode scanner 3, and the customer aligns the payment code with the barcode scanner 3 to complete the payment.
[0049] In summary, the automatic medicine vending equipment forms a medicine taking device through the cooperation of the first motor 13, the first screw rod 14, the first guide rod 15, the mounting plate 16, the first moving part, the second moving part and the mechanical clamp 22. According to the position of the medicine, the mechanical clamp 22 is driven to move to take the medicine, and after taking the medicine, the mechanical clamp 22 and the medicine thereon are stably transported until the medicine is in contact with the protective pad 11 in the placement groove 10, that is, one medicine taking is completed. It is suitable for taking medicines of various materials, avoiding damage or breakage of the outer packaging of the medicine during the falling process due to collision, avoiding waste of medicine, and having high applicability. Through the cooperation of the control panel 2, the barcode scanner 3, the medicine display table 4, the induction light 5, the image collector 6 and the medicine taking device, it is used for automatically identifying the medicine, taking the medicine and selling it, avoiding the need for manual round-trip operation, speeding up the efficiency of taking the medicine and selling it, and reducing the possibility of misoperation and confusion caused by human factors, thereby improving work efficiency.
