Description

Technical Field

[0001] This application relates to the technical field of verifying product information, and in particular to a product verification device based on visual recognition. Background Technology

[0002] Pharmaceutical distribution is a crucial link connecting drug / medical device production with end-user use. One of its core tasks is to conduct rigorous quality and information verification of drugs and medical devices in the distribution process to ensure product traceability, tracking, and accurate information. In practice, a large number of drugs and medical devices are sorted, distributed, and stored in bulk. These bulk goods are usually individually or in small batches, with barcodes, QR codes, or electronic supervision codes printed on the outer packaging to identify product information. Therefore, before warehousing, outbound, inventory, or distribution, the outer packaging labels of each bulk item must be verified one by one to confirm key information such as name, specifications, batch number, expiration date, and manufacturer. This information must be compared with data in the management system to prevent counterfeit, expired, or incorrectly distributed drugs from entering the market. This verification process is a vital foundation for ensuring drug safety and achieving full traceability.

[0003] Currently, image recognition technology is widely used in automated verification systems for pharmaceutical distribution to assist in information collection. A typical solution involves mounting an industrial camera on a fixed bracket above the verification cabinet, facing downwards to capture images of the outer packaging of medicines or medical devices placed on the worktable from a vertical, overhead angle. By adjusting the camera's focus and lighting, the system can automatically identify barcodes, QR codes, and other markings on the packaging and upload the data to the management backend in real time. This enables automatic data entry and verification, reducing manual input errors and improving verification efficiency. This method has already been applied in some pharmacies, pharmaceutical warehouses, and logistics centers, achieving initial automation and digitization of the verification process.

[0004] However, existing technical solutions still have significant drawbacks. First, because the camera needs to capture images from directly above without obstruction, the space between the camera and the operating table must be completely unobstructed. This severely limits the placement of displays, operating terminals, or other auxiliary equipment by operators during the verification process, often resulting in the screen being placed to the side or far from the operating area, affecting the convenience of human-computer interaction and operational efficiency. Second, when medicines or medical devices are placed on the verification counter, their varying shapes and sizes create significant height differences at the top. Since cameras typically use a fixed-focus mode, they struggle to achieve clear imaging of objects at different heights, leading to some barcodes failing to be recognized due to inaccurate focus. This necessitates repeated adjustments or manual intervention, reducing the success rate of automated recognition and overall operational efficiency. Therefore, the existing top-down shooting verification method still faces technical bottlenecks in terms of spatial layout flexibility and image acquisition stability. Utility Model Content

[0005] This application provides a product verification device based on visual recognition. By placing the imaging component inside the verification cabinet and utilizing a transparent support plate to achieve bottom-up image acquisition, it solves the layout limitations of existing technologies where the imaging component must be placed above the camera, resulting in an unobstructed shooting space, and the technical problems of difficulty in focusing the imaging component due to varying product heights. The technical solution is as follows:

[0006] This application provides a product verification device based on visual recognition, comprising: a verification cabinet having a receiving chamber and a camera port located at the top; a transparent support plate disposed on the camera port, the transparent support plate having a support surface for placing the product to be verified, and the support surface being configured as a planar structure exposed at the top of the verification cabinet; a camera component disposed in the receiving chamber, with the camera component's shooting direction facing the transparent support plate; and a control switch disposed at the top of the verification cabinet, located on one side of the camera port, the control switch being signal-connected to the camera component for controlling the camera component to activate the visual function to verify the product on the transparent support plate.

[0007] In one embodiment, the control switch has an infrared sensing function to form a first region and a second region above the transparent support plate by infrared light emitted by the control switch, the second region being covered by infrared light emitted by the infrared sensor.

[0008] The camera's field of vision covers both the first and second areas. When a product is placed in the second area, a control switch is triggered to activate the camera's visual function for verification.

[0009] In one embodiment, the control switch includes: a first mounting base with a bent structure to form a first mounting surface and a second mounting surface on the first mounting base, the first mounting base being detachably mounted on the top outer wall of the verification cabinet via the first mounting surface, and the second mounting surface being perpendicular to the top outer wall of the verification cabinet; and an infrared sensing component mounted on the second mounting surface, the infrared sensing component having a first light-emitting part capable of emitting infrared light, the extension direction of the first light-emitting part being perpendicular to the second mounting surface, thereby forming a right-angle slot at the edge of the support surface through the second mounting surface and the first light-emitting part, the right-angle slot being used to limit and block products that block infrared light.

[0010] In one embodiment, it further includes a light source assembly disposed in the receiving chamber for illuminating the receiving chamber.

[0011] In one embodiment, the light source assembly includes: a second mounting base having a bent structure to form a third mounting surface and a fourth mounting surface on the second mounting base, the second mounting base being detachably mounted on the top inner wall of the verification cabinet via the third mounting surface, and the fourth mounting surface being perpendicular to the top inner wall of the verification cabinet; and a light source component mounted on the fourth mounting surface, the light source component having a second light-emitting part capable of emitting illuminating light, the second light-emitting part facing the inner side wall of the verification cabinet, and focusing the emitted illuminating light onto the inner side wall of the verification cabinet, thereby causing the illuminating light emitted by the second light-emitting part to be reflected by the side wall of the verification cabinet and cover the receiving chamber.

[0012] In one embodiment, the sidewalls inside the verification cabinet are covered with a functional coating that has a rough surface capable of diffusely reflecting illuminated light.

[0013] In one embodiment, the material of the functional coating is an epoxy-polyester blended powder coating that can be sanded.

[0014] In one embodiment, the device further includes: an adjustment assembly, wherein the imaging component is mounted on the side wall inside the verification cabinet via the adjustment assembly; the adjustment assembly includes: a base having a first adjustment rod and fixing blocks disposed at both ends of the first adjustment rod, the first adjustment rod extending along a first direction, and the fixing blocks being detachably mounted on the bottom side wall inside the verification cabinet; and a bracket mounted on the first adjustment rod and capable of sliding along the first direction on the first adjustment rod.

[0015] In one embodiment, the bracket includes: a first slider slidably mounted on a first adjusting rod; a second adjusting rod connected to the first slider and extending along a second direction perpendicular to the first direction; a second slider slidably mounted on the second adjusting rod; a third adjusting rod slidably embedded in the second slider and extending along a third direction perpendicular to both the first and second directions; and a third mounting base slidably mounted on the third adjusting rod, with the imaging component mounted on the third mounting base.

[0016] In one embodiment, the verification cabinet is configured as a cuboid structure, and a cabinet door capable of opening to accommodate the chamber is provided on one side of the verification cabinet; the transparent support plate is configured as a transparent tempered glass plate.

[0017] Compared to existing technologies, the product verification device based on visual recognition proposed in the above technical solution installs the imaging component within the receiving chamber of the verification cabinet, with the lens facing upwards and aligned with the transparent support plate located at the top imaging port, achieving a bottom-up reverse imaging method. This design completely eliminates the need for the imaging component and its support structure to be erected directly above the operating table in traditional solutions, allowing the space above the operating table to be fully used by the operator, no longer limited by the requirement of an unobstructed line of sight for the imaging component. Therefore, operators can freely arrange the display screen, operating terminal, or other auxiliary equipment according to ergonomic requirements, significantly improving the flexibility of the operating space and the convenience of human-computer interaction, and optimizing the overall work experience. Furthermore, by placing the product on the support surface of the transparent support plate and ensuring that the barcode or QR code on the product's outer packaging is aligned with this plane for imaging, a constant imaging distance is ensured for all products to be verified. Regardless of the height difference of the product itself, its marking information is always located on the same focal plane, which fundamentally eliminates the problem of focal length change caused by the height difference of the product. It effectively avoids the image blurring and recognition failure caused by the inaccurate focus of traditional high-speed document scanners, and greatly improves the accuracy of image recognition and the level of system automation.

[0018] In summary, this application not only breaks through the spatial layout limitations of traditional visual verification devices, achieving an unobstructed and highly flexible operating environment, but also solves the focusing problem in the identification of multi-specification products by unifying the imaging plane, significantly improving verification efficiency, recognition success rate, and system reliability. It has the advantages of reasonable structure, convenient operation, and strong adaptability, and is particularly suitable for application scenarios in the pharmaceutical distribution field for efficient and accurate information verification of bulk medicines and medical devices.

[0040] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0041] Reference Figure 1As shown, an embodiment of this application proposes a product verification device based on visual recognition, which may include: a verification cabinet 1 having a receiving chamber 101 and a shooting port 102 located at the top; a transparent support plate 2 disposed on the shooting port 102, the transparent support plate 2 having a support surface for placing the product to be verified, and the support surface being configured as a planar structure exposed at the top of the verification cabinet 1; a shooting component 3 disposed within the receiving chamber 101, and the shooting direction of the shooting component 3 being directly facing the transparent support plate 2; and a control switch 4 disposed at the top of the verification cabinet 1, located on one side of the shooting port 102, the control switch 4 being signal-connected to the shooting component 3, for controlling the shooting component 3 to activate the visual function to verify the product on the transparent support plate 2.

[0042] Specifically, in the technical solution adopted in this application, the product verification device may include: a verification cabinet 1, a transparent support plate 2, an imaging component 3, and a control switch 4. The verification cabinet 1 has a rectangular imaging port 102 at its top, and an internal receiving chamber 101. The transparent support plate 2 can be made of tempered glass and can completely cover the imaging port 102. Its top surface is a smooth support surface, flush with the top of the cabinet to form a horizontal placement plane. The imaging component 3 can be installed at the bottom of the receiving chamber 101, with its lens facing the transparent support plate 2, thus forming a fixed vertical imaging distance. The control switch 4 can be arranged at the top edge of the verification cabinet 1 and connected to the imaging component 3 via a wire or wireless connection. In use, the product is placed on the support surface, and the label on the product packaging indicating the category, model, and product name is affixed to the support surface. The imaging component 3 then vertically upwards to capture images to verify the product identification type, effectively ensuring that all products have the same imaging focal length based on the imaging component 3, avoiding the obstruction problem caused by the need to install a top imaging component 3 in traditional technologies. By adopting a bottom-up shooting method, it is possible to avoid the need to place the shooting component 3 on the top of the verification cabinet 1 via a bracket, thus avoiding the drawback that the shooting component 3 cannot be obstructed from the desktop shooting space and does not restrict the operation of personnel on the verification cabinet 1.

[0043] Furthermore, refer to Figure 1 As shown, in some embodiments, the control switch 4 has an infrared sensing function to form a first region and a second region above the transparent support plate 2 by infrared light emitted by the control switch 4, the second region being covered by infrared light emitted by the infrared sensor.

[0044] The camera component 3 has a visual range covering the first and second areas. When a product is placed in the second area, the control switch 4 is triggered to activate the visual function of the camera component 3 for verification.

[0045] Specifically, in the technical solution adopted in this application, the first area is the conventional placement area above the transparent support plate 2 that is not covered by infrared light, while the second area is a rectangular trigger area covered by infrared light. In the embodiment of this application, the visual range of the imaging component 3 covers the entire support surface, so as to be able to identify more products on the transparent support plate 2. In use, different products can be placed on the first area first. After the products are stably arranged on the transparent support plate 2, the products are then placed in the second area to block the light path of the infrared light, thereby triggering the control switch 4 to start the imaging component 3 for verification.

[0046] Furthermore, refer to Figure 3 As shown, in some embodiments, the control switch 4 includes: a first mounting base 41, which has a bent structure to form a first mounting surface 411 and a second mounting surface 412 on the first mounting base 41. The first mounting base 41 is detachably mounted on the top outer wall of the verification cabinet 1 through the first mounting surface 411, and the second mounting surface 412 is perpendicular to the top outer wall of the verification cabinet 1; an infrared sensing component 42, which is mounted on the second mounting surface 412. The infrared sensing component 42 has a first light-emitting part 421 capable of emitting infrared light. The extending direction of the first light-emitting part 421 is perpendicular to the second mounting surface 412, thereby forming a right-angle slot at the edge of the support surface through the second mounting surface 412 and the first light-emitting part 421. The right-angle slot is used to limit and block the product from emitting infrared light.

[0047] Specifically, in the technical solution adopted in this application, the first mounting base 41 can be set as an L-shaped bent part, and its first mounting surface 411 is fixed to the top outer wall of the verification cabinet 1 by bolts. The second mounting surface 412 is perpendicular to the top side wall of the verification cabinet 1 and faces the support surface. Since the second mounting surface 412 is higher than the support surface, the infrared sensing component 42 can be mounted on the second mounting surface 412, and the extension direction of the first light-emitting part 421 is perpendicular to the second mounting surface 412, thereby forming a right-angle slot. When the product is fixed in the right-angle slot, the infrared light emitted by the first light-emitting part 421 can be blocked to activate the shooting component 3 to shoot and verify, that is: place the product in the second area to trigger the control switch 4.

[0048] Furthermore, refer to Figure 2 As shown, in some embodiments, it further includes: a light source assembly 5, disposed in the receiving chamber 101, for illuminating the receiving chamber 101.

[0049] Specifically, in the technical solution adopted in this application, the light source component 5 is configured in the receiving chamber 101, which can provide a shooting environment with sufficient light source for the shooting component 3, so that the shooting component 3 can shoot the markings on the outer packaging of the product more clearly, and can also avoid the adverse effects of other light sources outside the verification cabinet 1 on the shooting environment.

[0050] Furthermore, refer to Figure 4 As shown, in some embodiments, the light source assembly 5 includes: a second mounting base 51, which has a bent structure to form a third mounting surface 511 and a fourth mounting surface 512 on the second mounting base 51. The second mounting base 51 is detachably mounted on the top inner wall of the verification cabinet 1 through the third mounting surface 511, and the fourth mounting surface 512 is perpendicular to the top inner wall of the verification cabinet 1; and a light source component 52, which is mounted on the fourth mounting surface 512. The light source component 52 has a second light-emitting part 521 capable of emitting illuminating light, and the second light-emitting part 521 faces the inner side wall of the verification cabinet 1 and focuses the emitted illuminating light onto the inner side wall of the verification cabinet 1, so that the illuminating light emitted by the second light-emitting part 521 is reflected by the side wall of the verification cabinet 1 and covers the receiving chamber 101.

[0051] Specifically, in the technical solution adopted in this application, to avoid insufficient image clarity due to specular reflection, the light source assembly 5 can be configured as a backlight in the receiving chamber 101. Specifically, the second mounting base 51 is configured as an L-shaped bent piece, with its third mounting surface fixed to the top inner wall of the verification cabinet 1 by bolts. The fourth mounting surface 512 is perpendicular to the top inner wall of the verification cabinet 1 and faces one of the side walls inside the verification cabinet 1. The light source component 52 is fixed on the fourth mounting surface 512, with the second light-emitting part 521 of the light source component 52 facing the side wall inside the verification cabinet 1. The illumination light emitted by the second light-emitting part 521 is focused on the inner side wall of the verification cabinet 1, so that the illumination light illuminates the receiving chamber 101 after being reflected by the inner side wall of the verification cabinet 1. This effectively avoids the illumination light directly shining on the transparent support plate 2, which would cause a ghost image due to light refraction and affect the verification accuracy.

[0052] Furthermore, in some embodiments, the sidewalls inside the verification cabinet 1 are covered with a functional coating, which has a rough surface capable of diffusely reflecting illuminated light.

[0053] Specifically, in the technical solution adopted in this application, in order to further avoid strong light reflection on the viewing support plate 2 caused by reflected illumination, a frosted finish can be applied to the inner wall of the verification cabinet 1 to form a rough surface. Illumination light shining on the rough surface will create a diffuse reflection effect. In this embodiment, a frosted functional coating is applied to the inner side wall of the verification cabinet 1 to form the required rough surface after frosting. This effectively improves the diffuse reflection efficiency of light. In use, the illumination light shines on the inner side wall of the verification cabinet 1 opposite the fourth mounting surface 512, and then diffuses evenly to the remaining inner walls, forming a sufficiently bright shooting environment. This not only significantly reduces interference from external ambient light, but also avoids reflections or strong light spots caused by specular reflection, improving the stability of image acquisition by the shooting component 3 during the shooting process.

[0054] Furthermore, in some embodiments, the material of the functional coating is a sanding-processable epoxy-polyester hybrid powder coating.

[0055] Specifically, in the technical solution adopted in this application, the functional coating can be applied to the inner side wall of the verification cabinet 1 using a classic spraying process. After the functional coating forms a rough surface on the inner side wall of the verification cabinet 1, it can achieve efficient diffuse reflection of light by reducing its gloss.

[0056] Furthermore, refer to Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, it further includes: an adjustment assembly 6, wherein the imaging component 3 is mounted on the side wall inside the verification cabinet 1 via the adjustment assembly 6; the adjustment assembly 6 includes: a base having a first adjustment rod 61 and fixing blocks 62 disposed at both ends of the first adjustment rod 61, the first adjustment rod 61 extending along a first direction, and the fixing blocks 62 being detachably mounted on the bottom side wall inside the verification cabinet 1; and a bracket mounted on the first adjustment rod 61 and capable of sliding on the first adjustment rod 61 along the first direction.

[0057] Specifically, in the technical solution adopted in this application, the adjustment component 6 has a three-dimensional adjustment function, that is, it can adjust the position of the imaging component 3 in three directions. The first adjustment rod 61 is fixed to the bottom side wall inside the verification cabinet 1 by the fixing block 62, and the first adjustment rod 61 extends along the width direction of the verification cabinet 1, that is, the first direction; and the bracket is slidably installed on the first adjustment rod 61 so that the position of the imaging component 3 can be adjusted along the first direction; and the bracket has a two-dimensional adjustment function, thereby realizing the adjustment of the position of the imaging component 3 in the other two directions.

[0058] Furthermore, refer to Figure 5As shown, in some embodiments, the bracket includes: a first slider 63 slidably sleeved on a first adjusting rod 61; a second adjusting rod 64 connected to the first slider 63 and extending along a second direction perpendicular to the first direction; a second slider 65 slidably sleeved on the second adjusting rod 64; a third adjusting rod 66 slidably embedded on the second slider 65 and extending along a third direction perpendicular to both the first and second directions; and a third mounting base 67 slidably sleeved on the third adjusting rod 66, with the imaging component 3 mounted on the third mounting base 67.

[0059] Specifically, in the technical solution adopted in this application, the bracket may include: a first slider 63, a second adjusting rod 64, a second slider 65, a third adjusting rod 66, and a third mounting base 67; the first slider 63 is sleeved on the first adjusting rod 61, and the first slider 63 may have a locking screw for locking the first slider 63 on the first adjusting rod 61; the second adjusting rod 64 is vertically connected to the first slider 63 and extends along the height direction of the verification cabinet 1, i.e., the second direction; the second slider 65 is slidably sleeved on the second adjusting rod 64 so as to adjust the position of the imaging component 3 along the second direction; the third adjusting rod 66 is horizontally embedded in the second slider 65, and the third adjusting rod 66 extends along the length direction of the verification cabinet 1, i.e., the third direction; the third mounting base 67 is slidably sleeved on the third adjusting rod 66 so as to adjust the position of the imaging component 3 along the third direction.

[0060] Furthermore, refer to Figure 1 As shown, in some embodiments, the verification cabinet 1 is configured as a cuboid structure, and a cabinet door 11 capable of opening and accommodating the chamber 101 is provided on one side of the verification cabinet 1; the transparent support plate 2 is configured as a transparent tempered glass plate.

[0061] Specifically, in the technical solution adopted in this application, the verification cabinet 1 can be set as a rectangular box structure made of metal, with external dimensions of 6000×5500×6500mm. A magnetic door 11 is provided on one side of the verification cabinet 1 to facilitate opening the cabinet 1 and maintaining or repairing the functional components in the receiving chamber 101. The exterior of the verification cabinet 1 is covered with white paint. The transparent support plate 2 can be made of chemically strengthened sodium-calcium tempered glass. The size of the tempered glass can be adapted to the size of the imaging port 102, i.e., 4900×3400mm, with a light transmittance ≥92% and an impact resistance of approximately 12J / cm². 2 .

[0062] In one embodiment, an integrated computer can be mounted on the verification cabinet 1 via a lifting bracket. This computer is electrically connected to the imaging component 3. This allows the information captured by the imaging component 3 to be entered into the computer, and the computer's display screen to show information such as the name and quantity of the verified products. Operators can then review the accuracy of the entered product information through the computer's display screen.
