[0002] With the rapid development of unmanned retail models, unmanned medicine vending machines are gradually entering people's lives, providing consumers with a convenient medicine purchasing experience. However, as a special commodity, the safety and accuracy of medicines are of paramount importance.

[0003] With the rapid evolution of unmanned retail models, intelligent drug vending machines are gradually penetrating public health service scenarios, providing consumers with convenient access to medicines through automation technology. However, as a special category of medical commodities, medicines require strict pharmaceutical management regulations to ensure safety and dispensing accuracy during distribution. Currently, unmanned drug vending machines generally lack a secondary verification mechanism for dispensed medicines, which may lead to dispensing accidents such as incorrect drug types and dosage deviations during automated sorting and delivery. This not only violates the requirements for accurate drug sorting but also may cause drug treatment risks due to medication errors, posing a potential threat to patient medication safety.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.

[0038] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0039] It should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the coordinate system shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] This utility model provides an automatic vending machine with verification function, see reference. Figure 1-6 It includes: a first cabinet 1 and a second cabinet 2, wherein the first cabinet 1 is provided with a shelf 13 and a conveying platform 3, and the conveying platform 3 is provided with a conveying mechanism 4 and a verification mechanism 5;

[0043] The verification mechanism 5 is used to inspect the target goods that fall onto the conveying mechanism 4;

[0044] The second cabinet 2 is provided with a picking bin 22 and a recycling bin 24. The conveying platform 3 is connected to the picking bin 22 in the first position and to the recycling bin 24 in the second position.

[0045] After the verification mechanism 5 completes the inspection, the target goods are transferred to the picking hopper 22 or the recycling bin 24 via the conveying mechanism 4.

[0046] The “connection” between the conveyor platform 3 and the picking bin 22 / recycling bin 24 does not refer to physical contact, but rather to the formation of a continuous conveying path between the end of the conveyor mechanism 4 and the corresponding bin entrance. The cargo aisle 14 on the shelf 13 can use a drop-down cargo aisle.

[0047] Specifically, after a user places an order on the vending machine's interface, the shelf 13 on the first cabinet 1 pushes the corresponding target product from the shelf 13 to the conveying mechanism 4 on the conveying platform 3. Before pushing, the conveying platform 3 moves from its initial position to the side of the corresponding aisle 14 of the target product. The conveying mechanism 4 then conveys the target product to the verification position of the verification mechanism 5. The verification mechanism 5 verifies the target product. If the target product matches the product purchased by the user, the conveying platform 3 moves from the side of the corresponding aisle 14 to a first position and connects with the retrieval bin 22. The transmission mechanism then conveys the target product into the retrieval bin 22. If the target product does not match the product purchased by the user, the conveying platform 3 moves from the side of the corresponding aisle 14 to a second position and connects with the recycling bin 24. The transmission mechanism then conveys the target product into the recycling bin 24. Correspondingly, if the target product does not match the product purchased by the user, the process of "the shelf 13 on the first cabinet 1 pushing the corresponding target product from the shelf 13 to the conveying mechanism 4 on the conveying platform 3" can be repeated after the incorrect target product is placed into the recycling bin 24.

[0048] In this embodiment, by setting up a verification mechanism 5 in the conveying platform 3, the target goods falling into the conveying mechanism 4 are inspected, so that the target goods are effectively screened before being delivered to the user, avoiding the user from taking away unqualified goods (such as misdelivered or damaged goods), and significantly improving the accuracy of sales transactions. At the same time, the conveying platform 3 is set to switch between a first position and a second position. In the first position, it is connected to the picking hopper 22, and in the second position, it is connected to the recycling bin 24. This allows qualified goods after verification to be accurately conveyed to the picking hopper 22, and unqualified goods to be conveyed to the recycling bin 24, realizing the classification and processing of goods. This reduces customer complaints caused by incorrect goods; after the verification agency 5 completes the inspection, the conveying agency 4 automatically delivers the target goods to the corresponding pickup bin 22 or recycling bin 24, enabling the entire vending process to complete the selection and distribution of goods without manual intervention, reducing the operator's labor costs and improving the operating efficiency of the vending machine; the recycling bin 24 centrally collects unqualified goods, allowing operators to more conveniently handle problematic goods in a unified manner (such as recycling, replacement, etc.), avoiding the accumulation of problematic goods in the pickup bin 22, ensuring the cleanliness of the pickup bin 22, and improving the overall management standardization of the vending machine.

[0049] In one embodiment, the conveying platform 3 includes a base plate, the conveying mechanism 4 is disposed on the base plate, and the verification mechanism 5 is installed on the base plate at one end away from the picking hopper 22 or the recycling bin 24.

[0050] The conveying mechanism 4 is mounted on the base plate, and the connection between the two must be firm and reliable. Bolt connections or similar methods can be used, ensuring that the connection points are evenly distributed to prevent relative displacement between the conveying mechanism 4 and the base plate due to vibration during operation, which would affect the stability of goods conveying. The base plate must have sufficient load-bearing capacity to support the conveying mechanism 4, the verification mechanism 5, and the weight of the goods during conveying, preventing deformation after long-term use. As the basic component of the conveying platform 3, the base plate's dimensions must be compatible with the internal space of the first cabinet 1, ensuring stable installation within the cabinet while also providing sufficient space for the conveying platform 3 to switch between the first and second positions, avoiding collisions with other components of the cabinet. The base plate can also be set at a certain angle. In this case, there are certain requirements for the material of the conveying mechanism 4 (so that the medicine can remain relatively stationary with respect to the conveying mechanism 4 during the conveying process). The base plate can be set to tilt towards the picking hopper 22 or the recycling bin 24, or towards the end away from the picking hopper 22 or the recycling bin 24, as needed. The verification mechanism 5 can also be set at a certain distance from the picking hopper 22 or the recycling bin 24 when the conveying platform 3 (base plate) is in the first position or the second position, so that the goods entering the conveying platform 3 from the shelf 13 can be verified by the verification mechanism 5.

[0051] In this embodiment, the verification mechanism 5 is installed at the end furthest from the picking hopper 22 or the recycling bin 24, allowing sufficient time for the drug goods to be inspected and transported. The parallelism of the base plate makes the transport more stable. By setting the base plate, the conveying mechanism 4 and the verification mechanism 5 are integrated on the base plate, forming a whole structure, which enhances the structural stability of the conveying platform 3, reduces the shaking of the conveying mechanism 4 and the verification mechanism 5 during operation, and ensures the stability of goods transport and inspection. As a basic structure, the base plate facilitates the overall position switching of the conveying platform 3 (between the first position and the second position). The base plate can drive the conveying mechanism 4 and the verification mechanism 5 to move synchronously, avoiding coordination errors that may occur if each component moves alone, and ensuring that the conveying platform 3 can accurately connect with the picking hopper 22 or the recycling bin 24 at different positions.

[0052] In one embodiment, such as Figure 3-6 As shown, the conveying platform 3 includes a first baffle 31 and a second baffle 32. The first baffle 31 and the second baffle 32 are respectively disposed on both sides of the conveying mechanism 4. The verification mechanism 5 is installed on the conveying mechanism 4 at one end away from the picking hopper 22 or the recycling bin 24.

[0053] The heights of the first baffle 31 and the second baffle 32 should be set according to the common height of the goods being sold to prevent the goods from falling off the sides due to shaking during the conveying process. At the same time, the distance between the two baffles (the width of the conveying mechanism 4) should be slightly greater than the width of the largest goods being sold (usually a certain distance is reserved) to ensure that the goods can pass through smoothly and also to play an effective limiting role. The two baffles can be fixed together using a support rod 34. The connection between the baffles and the conveying mechanism 4 must be firm and can be fixed by welding or high-strength bolts to prevent the baffles from loosening or tilting due to vibration when the conveying platform 3 switches positions (first position and second position) and when the conveying mechanism 4 is running, which would affect the limiting effect on the goods.

[0054] In this embodiment, the conveying platform 3 is configured as a first baffle 31 and a second baffle 32, which restricts the goods between the two baffles during the conveying process. This effectively prevents the goods from falling from both sides due to the shaking caused by the operation of the conveying mechanism 4 and the position switching of the conveying platform 3, thus ensuring the stability of the goods conveying process. At the same time, the protection of the goods by the baffles prevents the goods from colliding with other components inside the vending machine during the conveying and position switching process, reducing the probability of secondary damage to the goods due to collisions.

[0055] In other embodiments, the conveying platform 3 also includes a third baffle 33, which is disposed on the verification mechanism 5 and inclined toward the recycling bin 24 / picking bin 22. The maximum height of the third baffle 33 is lower than that of the first baffle 31 and the second baffle 32. By setting the third baffle 33, the goods are prevented from falling directly into the verification mechanism 5 and causing damage to the verification mechanism 5. At the same time, being lower than the first baffle 31 allows the goods to fall smoothly into the conveying platform 3.

[0056] In one embodiment, such as Figure 4-6 As shown, the conveying mechanism 4 includes a first drive motor 45, a drive wheel 41, a driven wheel 42, and a conveyor belt 43. The first drive motor 45 is driven to drive the drive wheel 41. The drive wheel 41 drives the driven wheel 42 to rotate through the conveyor belt 43. The drive wheel 41 and the driven wheel 42 are respectively disposed at both ends of the conveying platform 3. The first drive motor 45 is mounted on the conveying platform 3 and close to the drive wheel 41.

[0057] In this system, the driving wheel 41 and the driven wheel 42 are kept parallel. The tension of the conveyor belt 43 needs to be moderate. The connection between the output shaft of the first motor and the driving wheel 41 needs to be coaxial to reduce additional wear and noise caused by misalignment. The first drive motor 45 is mounted on the conveying platform 3 and close to the driving wheel 41, which shortens the transmission distance between the motor output shaft and the driving wheel 41, reduces energy loss during power transmission, improves transmission efficiency, and reduces the energy consumption of the equipment. If necessary, a support plate 44 is also provided below the conveyor belt 43 to support the conveyor belt 43, provide some guidance to the conveyor belt 43, and enable the goods to move on the conveyor belt 43, avoiding the weight of the goods from causing additional weight burden on the conveyor belt 43 and affecting the conveying efficiency.

[0058] In this embodiment, the first drive motor 45 drives the drive wheel 41, which in turn drives the driven wheel 42 to rotate via the conveyor belt 43, forming a stable transmission system. This allows the goods to move smoothly and at a constant speed on the conveyor platform 3, reducing positional deviations caused by shaking or speed changes during transport and improving the stability of the goods transport. The drive wheel 41 and driven wheel 42 are positioned at opposite ends of the conveyor platform 3, creating a longer transport path for the conveyor belt 43. This provides sufficient time and space for the verification mechanism 5 to conduct comprehensive inspections of the goods, ensuring that the verification mechanism 5 can accurately obtain relevant information about the goods and improving the accuracy of the verification results. In this embodiment, the conveyor mechanism 4 has a simple structure, mainly composed of the first drive motor 45, drive wheel 41, driven wheel 42, and conveyor belt 43. It has few components and is easy to install and disassemble. This makes the equipment easy to assemble during production and facilitates replacement and repair of faulty parts during later maintenance, reducing production and maintenance costs.

[0059] In one embodiment, such as Figure 6 As shown, the verification mechanism 5 includes a first camera, a second camera, and a third camera. The first camera is installed below the end of the conveyor belt 43 away from the picking hopper 22 or the recycling bin 24. The conveyor belt 43 is a transparent conveyor belt 43. The second camera and the third camera are arranged opposite to each other and are positioned above the first camera and the conveyor belt 43.

[0060] The first camera is used to acquire bottom images of the drug product, while the second and third cameras are used to acquire side images (from different sides) of the drug product. Figure 6The second camera is positioned diagonally opposite the conveyor platform 3, and the third camera is positioned diagonally opposite the conveyor platform 3. This allows for some overlap in the image capture range of the second and third cameras, resulting in more accurate information. Generally, the position of each camera should meet the focal length requirements for taking pictures. The three cameras can be set to trigger-based shooting. When the goods arrive at the designated area (such as the detection area of ​​the verification mechanism 5), the three cameras automatically and synchronously take pictures. By setting a sensor 5-10cm in front of the detection area of ​​the verification mechanism 5, sufficient signal transmission and conveyor belt 43 braking time can be reserved to ensure that the goods completely enter the detection area before stopping.

[0061] It should be noted that the verification agency 5 may also include a server, and the images captured by the camera will be transmitted to the back-end server for comparison with the (medicine) goods that the user needs to purchase.

[0062] Specifically, when the verification mechanism 5 is located at the end of the conveyor platform 3 that is furthest from the picking bin 22 / recovery bin 24 (with... Figure 2 For example, after the goods enter the conveyor platform 3, the conveyor mechanism 4 starts and moves towards the verification mechanism 5 (left). When the goods are conveyed into the verification mechanism 5, the conveyor mechanism 4 stops to facilitate the verification mechanism 5 to take pictures. After the pictures are taken, the conveyor mechanism 4 restarts and moves in the opposite direction (to the right) to convey the goods into the picking hopper 22 or the recycling bin 24. When the verification mechanism 5 is located in the middle of the conveyor platform 3, the goods enter the left side of the verification mechanism 5 in the conveyor platform 3 (with the left side facing the right). Figure 2 For example, the conveyor 4 starts and moves towards the verification mechanism 5 (right). When the goods are conveyed into the verification mechanism 5, the conveyor 4 stops to facilitate the verification mechanism 5 to take pictures. After the pictures are taken, the conveyor 4 restarts and moves in the same direction, conveying the goods into the picking hopper 22 or the recycling bin 24, or the goods enter the right side of the verification mechanism 5 in the conveyor platform 3 (for example). Figure 2 For example, the conveying mechanism 4 starts and moves towards the verification mechanism 5 (left). When the goods are conveyed into the verification mechanism 5, the conveying mechanism 4 stops to facilitate the verification mechanism 5 to take pictures. After the pictures are taken, the conveying mechanism 4 restarts and moves in the opposite direction (to the right) to convey the goods into the retrieval hopper 22 or the recycling bin 24.

[0063] In this embodiment, three cameras capture images of the goods from the bottom and sides. Combined with the light-transmitting properties of the transparent conveyor belt 43, the verification mechanism 5 can acquire multi-dimensional image information of the goods. Compared with single-view detection, it can comprehensively identify problems such as damage and incorrect labeling on the bottom and sides of the goods, greatly improving the comprehensiveness of the goods inspection. Images from different angles can be cross-verified, reducing the problems of missed or incorrect detection caused by misjudgment from a single viewpoint, and improving the accuracy of the verification results.

[0064] In one embodiment, the verification mechanism 5 further includes a first partition 54 and a second partition 55, such as Figure 4 and Figure 6 As shown, the first partition 54 is located in front of the second camera, and the second partition 55 is located in front of the third camera. Both the first partition 54 and the second partition 55 are transparent partitions.

[0065] The first partition 54 and the second partition 55 need to be perpendicular to the shooting direction of the second camera and the third camera (i.e., the plane of the partition is perpendicular to the center line of the lens). If there is any tilt (tilt angle exceeds 3°), it may cause light refraction, resulting in local distortion of the captured image (such as distortion of drug labels), which will affect the accuracy of image recognition.

[0066] In this embodiment, by setting a partition in front of the second and third cameras, the cameras are protected from damage during the transport of the target goods. In other embodiments, a third baffle 33 is also included, which can block excess light sources from the three cameras, resulting in better image quality.

[0067] In one embodiment, such as Figure 3 As shown, the vending machine also includes a lifting mechanism 6, which includes a first lifting column 61, a second lifting column 62, a first synchronous belt 63, a second synchronous belt, a drive shaft 64, and a second drive motor 65. The first lifting column 61 and the second lifting column 62 are respectively installed on both sides of the shelf 13. The first synchronous belt 63 is disposed on the first lifting column 61, and the second synchronous belt is disposed on the second lifting column 62. The drive shaft 64 is installed between the first lifting column 61 and the second lifting column 62 and is connected to the first synchronous belt 63 and the second synchronous belt. The second drive motor 65 is installed on the first lifting column 61 and is connected to the drive shaft 64. The conveying platform 3 is installed between the first synchronous belt 63 and the second synchronous belt.

[0068] The first lifting column 61 and the second lifting column 62 need to be installed vertically on both sides of the shelf 13, specifically on both sides in front of the shelf 13. The tension of the first synchronous belt 63 and the second synchronous belt need to be adjusted to be consistent. The power of the second drive motor 65 needs to be matched with the weight of the conveyor platform 3, the maximum load weight of the goods, and the lifting speed.

[0069] In this embodiment, the first and second lifting columns 62, together with the synchronous belt and drive shaft 64, form a symmetrical lifting structure, which enables the conveying platform 3 to maintain a horizontal state during the lifting process, preventing goods from slipping due to platform tilt and improving the stability of the lifting process. The lifting mechanism 6 drives the conveying platform 3 to flexibly adjust its height, which can accurately connect with the picking bin 22 to complete the delivery of qualified goods, and connect with the recycling bin 24 to handle problematic goods. Multi-position switching can be completed without manual intervention, reducing the redundant design of the mechanical structure and improving the space utilization efficiency of the vending machine. The lifting drive is achieved by synchronous belt transmission, which has lower noise than chain transmission, and the synchronous belt has less wear and a longer maintenance cycle, reducing the later maintenance cost of the equipment, while improving the user's shopping experience comfort.

[0070] In one embodiment, such as Figure 1-2 As shown, the second cabinet 2 is adjacent to and fits against the first cabinet 1. The first cabinet 1 is provided with a first cabinet door 11 for displaying goods. The second cabinet 2 is provided with a second cabinet door 21. The second cabinet door 21 is provided with a retrieval opening 23, which is connected to the retrieval hopper 22.

[0071] The first cabinet door 11 can be equipped with a transparent area to facilitate users to browse medicines and staff to check out out-of-stock medicines. An advertising screen 12 can also be installed to reduce the cost of the vending machine. The second cabinet door 21 can be equipped with a touch screen 27 for users to select medicines.

[0072] In this embodiment, the first cabinet door 11 displays the goods, allowing users to see the actual goods on the shelf 13. The independent second cabinet 2 is equipped with a retrieval bin 22 and a recycling bin 24, forming a functional partition with the shelf 13 and lifting mechanism 6 of the first cabinet 1. This reduces mutual interference between different functional modules, and the partition design facilitates targeted maintenance by operators (such as opening the second cabinet door 21 separately to clean the recycling bin 24), improving maintenance efficiency.

[0073] In one embodiment, such as Figure 1-2 As shown, the vending machine also includes an electrical control box 28, which is located in the second cabinet 2 and is electrically connected to the conveying mechanism 4 and the conveying platform 3.

[0074] Among them, such as Figure 2 As shown, the electrical control box 28 is located at the upper part of the second cabinet 2, and the recycling bin 24 and the dispensing bin 22 are located at the lower part of the second cabinet 2. The location of the electrical control box 28 is in a closed state (specifically, it is not connected to the recycling bin 24 and is not affected by the constant temperature device). The door of the second cabinet 2 with the electrical control box 28 is equipped with a touch screen 27, which facilitates customers to select goods and enhances the space utilization of the vending machine.

[0075] In this embodiment, by placing the electrical control box 28 in the second cabinet 2 and electrically connecting it to the conveying mechanism 4 and the conveying platform 3, the electrical control box 28 can centrally control these two core components, reducing signal delay or loss of control caused by decentralized control, and improving the coordination and stability of component operation. By centrally managing the circuit connections of the conveying mechanism 4 and the conveying platform 3 through the electrical control box 28, the wiring layout is more organized. During later maintenance, only the second cabinet 2 needs to be opened to inspect and repair the electrical control box 28 and related wiring, without disassembling other components, which greatly improves maintenance efficiency. The electrical connection between the electrical control box 28 and the conveying mechanism 4 and the conveying platform 3 enables real-time monitoring of these two components (such as operating status and fault alarms). When a component malfunctions, the electrical control box 28 can promptly provide feedback, facilitating operators to quickly locate and handle the problem, reducing equipment downtime.

[0076] In other embodiments, such as Figure 1 As shown, the second cabinet 2 is also equipped with an ID card scanner 26 and a QR code scanner 25, located below the electrical control box 28. Their scanning ports are adjacent and merged into a scanning area, located below the touch screen 27. By setting up the ID card scanner 26 and the QR code scanner 25 in the second cabinet 2, users are provided with a variety of interaction methods. The ID card scanner 26 can be used for identity verification (such as when purchasing specific types of goods), and the QR code scanner 25 supports mobile QR code payment, meeting the needs of different users and improving the interactive convenience of the vending machine. It also makes it convenient for users to verify their ID cards / scan QR codes to pay after selecting goods. The dispensing hopper 22 is located below the two scanners, and the recycling bin 24 is located below the dispensing hopper 22. The recycling bin 24 has a lockable door in the part corresponding to the second cabinet door 21. In summary, the upper part of the second cabinet door 21 is equipped with a touch screen 27, and the lower part of the touch screen 27 is equipped with a scanning area (including the scanning ports of the QR code scanner 25 and the ID card scanner 26). The dispensing port 23 is located below the scanning area, and the door of the recycling bin 24 is located below the dispensing port 23.

[0077] In one embodiment, the vending machine further includes casters 9 and support columns 10, which are located at the lower ends of the first cabinet 1 and the second cabinet 2 (the first cabinet 1 and the second cabinet 2 are connected). The casters 9 facilitate the movement of the vending machine, and the support columns 10 are used to support the vending machine. When it is necessary to move the vending machine, the support columns 10 can be folded up.

[0078] In one embodiment, the vending machine is equipped with a temperature control device, and the recycling bins 24 of the first cabinet 1 and the second cabinet 2 are connected and are both within the effective range of the temperature control device. This is suitable for vending machines that sell medicines and other goods that require refrigeration or storage at a specific temperature. The vending machine is equipped with an antenna 8, which is installed on the top outer side of the second cabinet 2 and can be used for remote management of the vending machine (such as uploading product inventory and fault alarms).

[0079] In one embodiment, a light box 7 can be installed above the first cabinet 1 for lighting and indication.

[0080] like Figure 7-8 As shown, this utility model also provides a control method for a vending machine with verification function, used in any of the embodiments of the first aspect described above. The executing entity can be a controller or a smart terminal, which is installed in the second cabinet of the vending machine. In one embodiment, the control method includes:

[0081] S110, receive a goods shipment instruction, and control the target goods to be shipped from the shelf according to the shipment instruction so that the target goods fall into the conveyor platform;

[0082] Taking pharmaceuticals as an example, the shipment instructions include basic pharmaceutical information, compliance verification information (since pharmaceuticals are special commodities, some shipment instructions for pharmaceuticals need to be linked to the user's identity verification results), and precise location information.

[0083] Specifically, when a user selects and successfully pays for medications on the touchscreen, an order is generated. Based on this order, a shipment instruction for the purchased medications is generated. Upon receiving the shipment instruction, the aisles on the shelf dispatch the medications, which then enter the conveyor platform. The conveyor platform can reach the location of the medications purchased by the user in the aisle before shipment to prevent the medications from getting stuck or damaged during descent due to excessive distance between them and the platform.

[0084] S120, the goods are inspected by the verification agency;

[0085] The inspection includes information about the target goods. Taking medicines as an example, this includes basic information such as the name of the medicine (e.g., "ibuprofen sustained-release capsules"), specifications (e.g., "0.3g / capsule, 20 capsules / box"), weight, and indications. If necessary, it can also include the production batch number (for tracing production batches) and expiration date (e.g., "May 2026"). It can also include the integrity information of the medicine (whether the packaging and seal are intact). If the goods pass the inspection, they are sent to the picking bin; if they fail, they are sent to the recycling bin. This system is used to track and trace the sale of medicines and check their shelf life and integrity during the verification process. The verification agency is mainly used to extract information from the target product and verify the extracted information against the product shipment instructions (the first verification is before the product is pushed from the shelf to the conveyor platform, the core of which is "matching and verifying the instructions with the inventory" - order verification; the second verification, or review, is after the medicine is pushed from the shelf to the conveyor platform and before the conveyor agency transports the medicine to the picking bin or recycling bin - physical review). During the review, it is necessary to ensure that the medicine information (of the target product) completely matches the medicine information in the shipment instructions to prevent the wrong medicine from being shipped.

[0086] Specifically, after the medicine goods enter the conveying platform, the conveying mechanism is activated, transporting the medicine goods to the inspection range of the verification mechanism. Three cameras (first, second, and third cameras) acquire multi-sided images of the medicine goods, extract information from the images, and then inspect the information. In other embodiments, the cameras can be replaced with scanners, and multiple scanners scan the medicine goods. By scanning the barcode or QR code on the medicine goods, detailed information about the medicine goods can be obtained. The method for extracting information from the acquired images can be any existing technology that can achieve this function.

[0087] S130, based on the inspection results, control the conveying mechanism to convey the target goods to the picking hopper or the recycling bin.

[0088] The inspection results include conclusions of "qualified" and "unqualified". "Qualified" includes meeting the sales conditions, that is, the information in the target product and the shipping instruction are consistent (a necessary condition), and the drug is intact and within its shelf life, etc. "Unqualified" includes information discrepancies, damaged packaging, lack of eligibility to purchase, etc.

[0089] This step (S130) specifically includes: S131, when the inspection result is qualified, controlling the conveying platform to convey the target goods to the picking hopper.

[0090] A qualified inspection result means that the relevant information of the target goods detected matches the relevant information of the goods in the goods shipment instruction.

[0091] Specifically, when the inspection result is qualified, the conveyor platform is activated, transferring the medicine to the retrieval hopper. This includes several conveying methods: While the medicine is being sent to the verification agency (within the testing range), the conveyor platform moves to the horizontal position of the retrieval hopper (i.e., the first position). When the inspection result is qualified, the conveyor can directly transfer the medicine to the retrieval hopper; or, after the verification agency completes the inspection, when the inspection result is qualified, the conveyor platform moves to the first position, and the conveyor is activated simultaneously, so that the medicine is just ready to be transferred into the retrieval hopper when the conveyor platform reaches the first position; or, after the verification agency completes the inspection, the conveyor is activated, transferring the medicine to the vicinity of the other end of the conveyor platform and then stopping. When the inspection result is qualified, the conveyor platform moves to the first position, and when the conveyor platform reaches the first position, the conveyor is activated, transferring the medicine into the retrieval hopper.

[0092] When the inspection result is unqualified, the conveying platform moves simultaneously during the conveying process of the medicine. When the conveying platform moves to the horizontal position of the recycling bin, the medicine is transferred to the recycling bin.

[0093] S132, when the inspection result is unqualified, control the conveying platform to convey the target goods to the recycling warehouse.

[0094] When the inspection result is unqualified, the product shipment instruction will be re-produced according to the order, and after the transmission platform completes the transmission, the steps of picking up (S110), inspection (S120) and delivery (S130) will be carried out again according to the shipment instruction.

[0095] Specifically, when the inspection result is unqualified, the conveyor platform is activated to transport the drug goods to the recycling bin. This includes several conveying methods: While the drug goods are being sent to the verification agency (within the testing range), the conveyor platform moves to the horizontal position of the recycling bin (i.e., the second position). When the inspection result is unqualified, the conveyor mechanism can directly transport the drug goods to the recycling bin; or while the drug goods are being sent to the verification agency (within the testing range), the conveyor platform moves to the horizontal position of the retrieval hopper (i.e., the first position). When the inspection result is unqualified, the conveyor platform moves from the first position to the second position, and then the transmission mechanism is activated to transport the drug goods into the recycling bin (this can be replaced with: conveyor...). The platform moves from the first position to the second position, and the conveying mechanism is activated simultaneously. When the conveying platform reaches the second position, the medicine can be conveyed into the recycling bin. Alternatively, after the medicine is inspected by the verification agency, if the inspection result is unqualified, the conveying platform moves to the second position, and the conveying mechanism is activated simultaneously. When the conveying platform reaches the second position, the medicine can be conveyed into the recycling bin. Alternatively, after the medicine is inspected by the verification agency, the conveying mechanism is activated, conveying the medicine to the vicinity of the other end of the conveying platform and then stopping. If the inspection result is unqualified, the conveying platform moves to the second position, and when the conveying platform reaches the second position, the conveying mechanism is activated, conveying the medicine into the recycling bin.
