Description

Technical Field

[0001] The utility model relates to the technical field of identification information collection, in particular to an identification information collection device. Background Art

[0002] In the process of product packaging, companies usually place anti-counterfeiting or traceability labels on the product packaging to prevent counterfeiting. These labels can be used to query or trace the product, so that consumers can check whether the product is authentic when purchasing.

[0003] Commonly used identifiers include QR codes and barcodes, but these are not the only ones. There are many different types of identifiers. Before a product leaves the factory, identifier information must be collected and stored for consumers to view. However, while some identifiers can be captured using scanners, others lack corresponding capture tools. For example, combinations of text, numbers, and patterns must be manually entered, which is time-consuming and labor-intensive. Furthermore, existing identifier scanners typically only capture one type of identifier, making them limited in applicability. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the present utility model provides an identification information collection device.

[0005] The technical solution of this utility model is as follows:

[0006] A device for collecting identification information includes a light shield, a light source located above the light shield, and a camera located on the rear side of the light shield. The light shield is provided with a light projection port corresponding to the light source at the top, a storage port at the bottom, and a shooting port on the rear side wall for the camera to capture an image of the identification.

[0007] The light source projects light onto the inner wall of the light shield;

[0008] It also includes a positioning sensor located on one side of the light shield. A detection hole corresponding to the positioning sensor is provided on the side wall of the light shield for the positioning sensor to detect the position of the product. The positioning sensor is communicatively connected with the light source and the camera.

[0009] During use, the product's identification mark is positioned toward the rear of the light shield and placed inside from below. When the positioning sensor detects the product, it triggers a start signal to the light source and camera, activating both simultaneously to capture the identification image. The captured image is then sent to the backend for processing, data collection, and storage. This device replaces manual input with image capture of identification information, saving time and effort. It requires minimal or no human intervention for product placement, thus reducing labor costs. Furthermore, this image capture method is applicable to a wide range of identification types, making it more widely applicable.

[0010] The sunshade is preferably in the shape of a vertical tube. The cylindrical inner wall can reflect light at multiple angles, making the light inside the sunshade softer and avoiding strong reflections or high exposure on the logo, which would make the photos taken by the camera unclear.

[0011] In order to ensure sufficient lighting and to cover the entire space inside the sunshade, two light sources are provided, which are symmetrically arranged relative to the vertical plane connecting the shooting port and the center of the sunshade.

[0012] Furthermore, the two light sources are horizontal strip light sources, arranged in a V shape, and their proximal ends are close to the shooting port. The two light sources project light obliquely downward to opposite sides of each other, and the light is projected at positions close to both sides of the shooting port, so that the light is mainly concentrated in the half area corresponding to the logo, effectively utilizing the light source, and reducing the power of the light source while obtaining sufficient lighting.

[0013] In order to facilitate the placement of products in the light shield and improve the efficiency of the placement operation, a door-shaped notch is provided on the front side of the light shield.

[0014] Preferably, the positioning sensors include two, arranged vertically. The lower positioning sensor detects the height of the product. When a product is detected, the marker aligns with the camera port, and the positioning sensor triggers a start signal to the light source and camera. The upper positioning sensor detects abnormalities and is connected to an external warning device. When the positioning sensor detects a product, it indicates that the product is placed too high, triggering a signal to the warning device. If the camera is not triggered to take a picture before this, it indicates that the camera and / or the lower positioning sensor have malfunctioned.

[0015] Since different products have different sizes, the positions of different logos will also be different. In order to improve the applicability of the device, the installation positions of the two positioning sensors can be adjusted according to the product size and the logo position. For this purpose, the detection hole is set as a vertical strip hole, and its upper and lower ends are close to the upper and lower ends of the light shield respectively to accommodate positioning sensors at different heights.

[0016] In order to improve the clarity of the pictures captured by the camera, the identification information collection device also includes a transparent light plate, which is located between the shooting port and the shooting path of the camera. The transparent light plate is surrounded by fill lights that irradiate from its edge to the center. The fill light of the transparent light plate can improve the brightness of the identification area captured by the camera, avoiding the appearance of dark areas in the image, which affects the clarity of the image.

[0017] In order to achieve better space utilization, the identification information collection device also includes a reflector, and the camera obtains the identification image in the light shield through the reflector. In this way, the placement of the camera can be adjusted according to the specific spatial layout relationship to better utilize the space and reduce the size of the space occupied by the device.

[0018] Preferably, the camera is located directly below the reflector, the reflector is horizontally aligned with the shooting port, and the camera is placed vertically to reduce the lateral size of the device.

[0019] This utility model provides a device for collecting identification information. This device uses images to capture identification information instead of manual input, saving time and effort. It also requires no or only minimal manual effort, such as picking and placing products, thus saving labor costs. Furthermore, the image-based identification method is applicable to a wide range of identification types, making it more widely applicable. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figures 1 to 3 As shown, the present invention provides an identification information collection device, which is primarily used to collect identification information on rigid packaging, such as cartons and bottles. Liquor bottles are typically capped with a product identification, such as the brand, production batch, production date, or some secret code, on the side of the bottle cap or on the cover when they are canned. This embodiment uses liquor bottles as an example to detect the identification information on the bottle cap or cover.

[0027] The identification information collection device includes a light shield 1, a light source 2 located above the light shield 1, and a camera 3 located on the back side of the light shield 1. The light shield 1 is provided with a light projection port corresponding to the light source 2 at the top and a storage port at the bottom. The rear side wall is provided with a shooting port 11 for the camera 3 to capture the identification image.

[0028] The light source 2 projects light onto the inner wall of the light shield 1;

[0029] The identification information collection device also includes a positioning sensor 4, which is located on one side of the light shield 1. A detection hole 12 is provided on the side wall of the light shield 1 corresponding to the positioning sensor 4 for the positioning sensor 4 to detect the product position. The positioning sensor 4 is communicatively connected to the light source 2 and the camera 3.

[0030] When in use, the mark of the product to be inspected, that is, the mark on the bottle cap or bottle cover of the wine bottle, is placed toward the back side of the light shield 1 and is placed into the light shield 1 from the bottom of the light shield 1. When the sensor 4 to be positioned detects the product, it triggers a start signal to the light source 2 and the camera 3. The light source 2 and the camera 3 are started at the same time to complete the acquisition of the identification image. The acquired image will be sent to the background for processing, information collection, and storage. This device replaces manual entry with image acquisition of identification information, saving time and effort. In addition, the placement of the product (i.e., the wine bottle) can be done manually or by an intelligent mechanical mechanism, such as a manipulator or other displacement mechanism. Therefore, no or only a small amount of manual participation is required, i.e., picking and placing the product, saving labor costs. In addition, the image acquisition identification method can be applied to various types of identification and has a wider applicability.

[0031] Specifically, the sunshade 1 is preferably in the shape of a vertical tube. The cylindrical inner wall can reflect light at multiple angles, making the light inside the sunshade 1 softer, avoiding strong reflections or high exposure on the logo, which affects the clarity of the photos taken by the camera 3.

[0032] In order to facilitate the placement of products in the light shield 1, a door-shaped notch 13 is provided on the front side of the light shield 1 to reduce the amplitude of the up and down movement when placing products, especially for some products of higher height, saving time for placing products and improving operation efficiency.

[0033] The light source 2 is installed above the upper port of the light shield 1, and preferably includes two light sources, which are symmetrically arranged relative to the vertical plane of the line connecting the shooting port 11 and the center of the light shield 1, so as to provide sufficient lighting and make the lighting as uniform as possible.

[0034] Specifically, the two light sources 2 are horizontal strip light sources arranged in a V shape, and their proximal ends are close to the shooting port 11. The two light sources 2 project light obliquely downward to opposite sides of the two light sources. The light is projected at positions close to both sides of the shooting port 11, so that the light is mainly concentrated in the half area corresponding to the logo. The light source 2 is effectively utilized, and the power of the light source 2 can be reduced while obtaining sufficient illumination.

[0035] The present application does not employ the light source 2 to project light directly toward the shooting port 11 or the location of the logo. This is because projecting light directly toward the shooting port 11 would cause the light to pass directly through the shooting port 11 and be captured by the camera 3, reducing the contrast brightness of the logo in the image captured by the camera 3 and affecting the clarity of the logo. Furthermore, since the shooting port 11 occupies a portion of the area, projecting light in this direction would result in unsatisfactory reflection from the sidewalls of the light shield 1. Directly projecting light toward the logo would result in overexposure or strong localized reflection, affecting the clear image of the logo captured by the camera 3.

[0036] The two light sources 2 arranged in a V-shape in this application can maximize the amount of reflected light illuminating the half area where the logo is located. However, actual measurements have shown that, due to the size of the two light sources 2, the illumination intensity decreases at the junction where they meet, resulting in a darker area. Therefore, the logo information acquisition device further includes a transparent light panel 5 located in the path between the camera 3 and the shooting port 11. The transparent light panel 5 is surrounded by fill lights 6 that illuminate from its edges toward the center. The fill light from the transparent light panel 5 can improve the brightness of the logo area captured by the camera 3, preventing dark areas from appearing in the image and affecting image clarity.

[0037] In this embodiment, the transparent light plate 5 can be a specially treated transparent plate, for example, it can refract the light from the fill light 6 mainly to the darker area of the sign. After actual testing, the transparent light plate 5 can enhance the brightness of the darker area of the sign, making it almost equal to the brightness of the areas on both sides.

[0038] In this embodiment, the combination of the transparent light panel 5 and the fill light 6, as well as the two light sources 2, are preferably mounted in an adjustable manner to facilitate prior adjustment for optimal photography. The two light sources 2 are preferably adjustable in horizontal position and angle, and the combination of the transparent light panel 5 and the fill light 6 is preferably adjustable in vertical and horizontal position.

[0039] Preferably, the positioning sensor 4 is preferably matched with a lifting mechanism, which is used to raise the height of the product so that it can enter the light shield 1, but the present application is not limited to this. The identification information collection device can also be used when manually placed. The positioning sensor 4 will be explained below using the lifting mechanism as an example of a matching object.

[0040] The positioning sensors 4 preferably include two, arranged vertically. In this embodiment, the positioning sensors 4 are preferably photoelectric sensors.

[0041] The positioning sensor 4 located below is used to detect the height position of the product. When the lifting mechanism lifts the product from under the light shield 1 to be detected by the positioning sensor 4 located below, the mark corresponds exactly to the shooting port 11. At the same time, the positioning sensor 4 triggers a start signal to the light source 2 and the camera 3 to complete the image capture of the mark.

[0042] The upper positioning sensor 4 is used for abnormal protection detection and is connected to an external warning device (not shown). When the positioning sensor 4 detects a product, it indicates that the product is placed too high, triggering a signal to the warning device. When the lifting mechanism is in use, the positioning sensor 4 also communicates with the lifting mechanism, sending a signal to the warning device and the lifting mechanism at the same time, causing the lifting mechanism to stop moving and avoid collision with the light shield 1. If the camera is not triggered before the photo is taken, it also indicates that the camera 3 and / or the positioning sensor 4 located below has malfunctioned.

[0043] In addition, since different products have different sizes, the positions of different logos will also be different. In order to improve the applicability of the device, the installation positions of the two positioning sensors 4 can be adjusted according to the product size and the logo position. For this purpose, the detection hole 12 is set as a vertical strip hole, and its upper and lower ends are respectively close to the upper and lower ends of the light shield 1 to accommodate the positioning sensors 4 at different heights.

[0044] In addition, in this embodiment, the angles between the detection hole 12 and the shooting port 11 and the center of the light shield 1 are preferably 90 degrees to prevent the light from the positioning sensor 4 from affecting the image captured by the camera 3.

[0045] like Figure 2 and Figure 3 As shown, in order to achieve better space utilization, the identification information acquisition device also includes a reflector 7, which is arranged on the outside of the light shield 1. The camera 3 obtains the identification image inside the light shield 1 through the reflector 7. In this way, the placement position of the camera 3 can be adjusted according to the specific spatial arrangement relationship to better utilize the space and reduce the size of the space occupied by the device.

[0046] Preferably, the camera 3 is located directly below the reflector 7, the reflector 7 is horizontally aligned with the shooting port 11, the mirror surface is tilted downward by 45 degrees, and the camera 3 is placed vertically, which can reduce the lateral size of the device.

[0047] The transparent light panel 5 is preferably located between the shooting port 11 and the reflector.

[0048] This utility model provides a device for collecting identification information. This device uses images to capture identification information instead of manual input, saving time and effort. It also requires no or only minimal manual effort, such as picking and placing products, thus saving labor costs. Furthermore, the image-based identification method is applicable to a wide range of identification types, making it more widely applicable.
