Technical Field
[0001] The utility model belongs to the technical field of article information identification, and in particular relates to a community health medicine tracing device and a light source thereof. Background Art
[0002] Existing camera-related lighting technologies primarily focus on improving performance in two key areas: reducing power consumption and increasing brightness. However, our company's all-in-one camera, designed for community-based drug traceability, has very low requirements for improving the brightness and reducing power consumption of the camera's light source. However, it places higher demands on ensuring uniform brightness and eliminating reflections on the target object captured by the camera.
[0003] The all-in-one machine for visual code scanning and verification of pharmaceutical consumables (a complete product applied to a light source) plays an irreplaceable role in pharmaceutical inventory management. In existing equipment for visual identification of pharmaceutical consumables, the vertical field of view of the light source used is offset by a small angle, and the brightness values of the chassis and the target object are very high. At positions that are far away from the vertical field of view of the light source or have a large offset, the brightness is relatively dim. This will cause trouble in taking pictures of medicine boxes and identifying drug traceability codes and product barcodes. In the actual photo identification process, the surface of the medicine box will reflect light, and the photographed picture will show some areas exposed and some areas insufficiently lit, making it impossible to obtain effective image information, unable to identify the product information on the medicine box, and unable to achieve the purpose of verifying, checking, scanning, and tracing the medicine. Utility Model Content
[0004] The purpose of the utility model is to provide a community health drug tracing device and its light source, which can solve the problem of uneven brightness on the surface of the target object, improve the clarity of the image, and quickly identify the barcode on the medicine box, and accurately achieve the purpose of tracing the drugs in and out of the pharmacy and checking the drugs on the prescription.
[0005] The utility model is implemented as follows: a light source of a community health drug tracing device comprises a housing, a lamp board and a light guide cover, wherein the lamp board is fixed on the housing and is provided with a plurality of LED lamp beads; the light guide cover is fixed on the housing and covers the lamp board, the light guide cover is made of a light-transmitting material, and a plurality of concave lenses distributed in a dot matrix are provided on the outer surface of the light guide cover, and the concave lenses are formed by the outer surface of the light guide cover being recessed inward.
[0006] Furthermore, the center line of the LED lamp bead is inclined to the board surface of the lamp board, and the light guide cover is conical, and the top diameter is larger than the bottom diameter.
[0007] Furthermore, the angle between the center line of the LED lamp bead and the board surface of the lamp board ranges from 60° to 65°.

[0009] Furthermore, the lamp board has a hollow area, and the housing and the light guide cover are also provided with hollow areas at positions corresponding to the hollow area of the lamp board.
[0010] Furthermore, the light guide cover is made of PC transparent material.
[0011] Furthermore, the material used to make the light guide cover includes astigmatism powder.
[0012] To achieve the above-mentioned purpose, the present invention also provides a community health drug tracing device, comprising a camera, a chassis for holding identified drugs, and a processor. A light source of any of the above items is provided above the chassis, and the light source is used to provide uniform lighting to the identified drugs; the camera is used to collect image information of the identified drugs and send it to the processor, and the processor compares the received image information with the ID information pre-stored therein to verify whether the current drug is a registered drug.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention; the terms "first", "second", and "third" are only used for descriptive purposes and should not be understood as indicating or implying relative importance; in addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or it can be a communication between the internal parts of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] Please refer to Figures 1 to 4 , shows a light source for a community health drug traceability device provided by this embodiment, comprising a housing 1, a light board 2, and a light guide 3. The light board 2 is fixed to the housing 1 and is equipped with a plurality of LED lamp beads 21. The light guide 3 is fixed to the housing 1 and covers the light board 2. The light guide 3 is made of a translucent material and has a plurality of concave lenses 31 arranged in a dot matrix on its outer surface.
[0025] Specifically, the light guide cover 3 has a light transmittance of 87% and a thickness of 1.5 mm. It is preferably made of PC transparent material. In order to enhance the light diffusion capability of the light guide cover 3 , astigmatism powder is added to the manufacturing material at a ratio of 5:1.
[0026] The concave lens 31 is formed by the outer surface of the light guide cover 3 being recessed inward. In actual production, the concave lens 31 can be made by a collision mold structure.
[0027] Preferably, a plurality of LED lamp beads 21 are arranged in a dot matrix on the light board 2, with the centerline of each LED lamp bead 21 tilted relative to the surface of the light board 2. The angle between the centerline of the LED lamp bead 21 and the surface of the light board 2 ranges from 60° to 65°, preferably 62°. The light guide 3 is conical, with a diameter at the top greater than the diameter at the bottom.
[0028] Please refer to Figure 5 Since the concave lens 31 has the function of scattering light, the light is refracted when passing through the light guide cover 3, and is diffused after being emitted from the outer surface of the light guide cover 3, and is evenly irradiated on the photographed medicine box on the chassis. The residual light can be used to illuminate the bright field, and the main light can be used to illuminate the dark field at a distance, avoiding the large-scale difference between the bright and dark fields and the serious exposure problem of the reflective medicine box, thereby quickly identifying the barcode on the medicine box, and accurately realizing the traceability of medicines in and out of the pharmacy and the verification of medicines with prescriptions.
[0029] Furthermore, in order to improve the heat dissipation effect of the light source, the shell 1 is made of aluminum alloy, and one side thereof has an annular mounting groove 11. The lamp board 2 is fixed in the mounting groove 11. The lamp board 2 and the shell 1 have a large contact area, which is conducive to the heat on the lamp board 2 being transferred to the shell 1 and dissipated to the outside by the shell 1, thereby preventing the LED lamp beads 21 from overheating, burning or aging, which is conducive to increasing the service life of the product.
[0030] In order to further avoid the problem that the brightness of the chassis is very bright within the vertical angle range of the LED lamp bead 21, and the brightness is relatively dim at a position relatively far away from the vertical plane of the LED lamp bead 21, the lamp board 2 of this embodiment has a hollow area 22, and the shell 1 and the light guide cover 3 are also provided with a hollow area at a position corresponding to the hollow area of the lamp board 2. Through this design, the light intensity within the vertical angle range of the LED lamp bead 21 can be weakened, and the light intensity at a position relatively far away from the vertical plane of the LED lamp bead 21 can be enhanced, thereby further avoiding the difference between bright and dark fields and making the captured image clearer.
[0031] This embodiment also provides a community health drug traceability device, including a camera, a chassis for holding identified drugs, and a processor. The above-mentioned light source is provided above the chassis, and the light source is used to provide uniform lighting to the identified drugs; the camera is used to collect image information of the identified drugs and send it to the processor, and the processor compares the received image information with the ID information pre-stored therein to verify whether the current drug is a registered drug.
[0032] The community health drug traceability device of this embodiment can be applied to drug inventory management and play an irreplaceable role. For example, it can be used to monitor drug storage status in real time. Once counterfeit or inferior products are verified, the system can issue an alarm to remind management to make adjustments. It can also integrate super-resolution decoding, intelligent AI text parsing algorithms, and target detection and recognition technologies to automatically identify and confirm. This not only improves pharmacy work efficiency, but also prevents inconsistencies between prescriptions and drugs, inconsistent quantities, and inconsistent usage, improves patient medication safety, and avoids medical accidents and medical risks in pharmacies.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
