Description

Technical Field

[0001] This utility model relates to the field of automated drug detection and information verification technology, and in particular to a drug box traceability code reading and information verification device that integrates all-around perspective detection. Background Technology

[0002] With the development of automated drug management and distribution technologies, the reading and verification of drug box traceability codes have played a crucial role in ensuring medication safety and achieving drug traceability. Currently, some devices on the market have drug box information recognition capabilities, but their detection methods still have limitations and cannot meet the complex and ever-changing drug box structures and printing specifications.

[0003] A search revealed an invention patent with publication number CN119647502A, which discloses a method, system, device, and medium for collecting drug traceability codes based on image recognition. While it describes visual acquisition for verifying drug traceability code information, it does not specifically address how to handle the different six-sided structures of various medicine boxes or the inconsistent placement of the traceability codes. Since there are no mandatory national regulations regarding the printing position of traceability codes on medicine boxes, this device may not be able to fully recognize traceability codes from different manufacturers and models, affecting the completeness and accuracy of information verification. Even if the vision system can acquire images of a specific area, the fixed camera position only allows acquisition of information from a single angle of the medicine box, failing to achieve omnidirectional visual inspection of all six sides. This can easily lead to missed traceability code information on non-target sides, resulting in missing information or misjudgments.

[0004] Therefore, it is necessary to design a medicine box traceability code reading and information verification device that integrates all-around perspective detection to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a medicine box traceability code reading and information verification device that integrates all-around perspective detection, so as to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A top detection camera is positioned above the mounting bracket and directly facing the conveying path of the conveying unit;

[0011] A bottom detection camera is positioned below the conveying unit and directly facing the conveying path of the conveying unit;

[0012] The left and right detection cameras are respectively set on the left and right sides of the conveying unit and aligned with each other on the conveying path of the conveying unit;

[0013] A front detection camera and a rear detection camera are respectively set at the front and rear ends of the mounting bracket and are tilted and aligned with the conveying path of the conveying unit;

[0014] The central processing unit is connected to the top detection camera, bottom detection camera, left detection camera, right detection camera, front detection camera, and rear detection camera via data cables.

[0015] Preferably, the mounting bracket is fixed to the conveying unit by bolts.

[0016] Preferably, both the top and bottom inspection cameras are high-resolution industrial cameras with their lens optical axes perpendicular to the conveying plane of the conveying unit. The top inspection camera is fixed to the top crossbeam of the mounting bracket by a first adjusting bracket, and the bottom inspection camera is fixed to the bottom frame of the conveying unit by a second adjusting bracket.

[0017] Preferably, both the left and right inspection cameras are wide-angle lens industrial cameras, with their lens optical axes horizontally aligned with the conveying path of the conveying unit. The left inspection camera is fixed to the left column of the mounting bracket by a third adjusting bracket, and the right inspection camera is fixed to the right column of the mounting bracket by a fourth adjusting bracket.

[0018] Preferably, both the front detection camera and the rear detection camera are installed at an angle, with their lens optical axes at a set angle to the conveying path of the conveying unit. The front detection camera is fixed to the front crossbeam of the mounting bracket by a fifth adjusting bracket, and the rear detection camera is fixed to the rear crossbeam of the mounting bracket by a sixth adjusting bracket.

[0019] The beneficial effects of this utility model are: by setting detection cameras in six directions (up, down, left, right, front, and back) of the conveying unit, this technical solution realizes all-round perspective detection of the six sides of the medicine box, and solves the problem of missing traceability code information caused by the fixed installation position of the camera in the prior art.

Detailed Implementation

[0023] Reference Figure 1 A medicine box traceability code reading and information verification device integrating all-around perspective detection, comprising a conveying unit 1 for carrying and transporting medicine boxes; the conveying part of the conveying unit 1 adopts a transparent structure, so that the image of the bottom of the medicine box can be captured through the transparent structure;

[0024] Mounting bracket 2 is fixedly mounted on the conveying unit 1 to support multiple detection cameras; top detection camera 3 is mounted above the mounting bracket 2 and faces the conveying path of the conveying unit 1 to capture images of the top surface of the medicine box.

[0025] Bottom detection camera 4 is set below the conveying unit 1 and faces the conveying path of the conveying unit 1, and is used to collect images of the bottom surface of the medicine box;

[0026] Left detection camera 5 and right detection camera 6 are respectively set on the left and right sides of the conveying unit 1 and aligned with each other on the conveying path of the conveying unit 1 to collect images of the left and right sides of the medicine box.

[0027] The front detection camera 7 and the rear detection camera 8 are respectively set at the front and rear ends of the mounting bracket 2 and are tilted and aligned with the conveying path of the conveying unit 1 to collect images of the front and rear sides of the medicine box.

[0028] The conveying unit 1, as the basic component of the entire device, is made of high-strength transparent material, and its surface is treated with an anti-slip coating to ensure that the medicine box will not slide or shift during conveying. The drive mechanism of the conveying unit 1 consists of a stepper motor and a synchronous belt. The stepper motor drives the conveying part of the conveying unit 1 to move at a constant speed through the synchronous belt. The transparent structure design of the conveying unit 1 allows the bottom detection camera 4 to capture images of the bottom surface of the medicine box through the transparent part, thereby realizing the acquisition of traceability code information on the bottom surface of the medicine box.

[0029] Side baffles are provided on both sides of the conveying unit 1 to restrict the lateral movement of the medicine box and prevent the medicine box from deviating from the conveying path.

[0030] The mounting bracket 2 is fixedly mounted on the conveying unit 1 to support multiple detection cameras and ensure their positional stability. The mounting bracket 2 is bolted to the conveying unit 1. The top detection camera 3 is fixed to the top crossbeam of the mounting bracket 2 via a first adjusting bracket 31. The first adjusting bracket includes a fixed base, an adjusting rod, and a locking knob. The fixed base is bolted to the top crossbeam, the adjusting rod is threaded to the fixed base, and the locking knob is used to lock the position of the adjusting rod. The optical axis of the lens of the top detection camera 3 is perpendicular to the conveying plane of the conveying unit 1 to ensure clear acquisition of the image of the top surface of the medicine box.

[0031] The bottom detection camera 4 is fixed to the bottom frame of the conveying unit 1 by the second adjustment bracket 41. The structure of the second adjustment bracket 41 is the same as that of the first adjustment bracket 31, including a fixed base, an adjustment rod and a locking knob. The fixed base is fixed to the bottom frame by bolts, the adjustment rod is connected to the fixed base by threads, and the locking knob is used to lock the position of the adjustment rod.

[0032] The optical axis of the lens of the bottom detection camera 4 is also perpendicular to the conveying plane of the conveying unit 1 to ensure clear acquisition of the image of the bottom surface of the medicine box. The bottom detection camera 4 is installed below the conveying unit 1 and directly facing the conveying path, acquiring the image of the bottom surface of the medicine box through the transparent structure of the conveying unit 1;

[0033] The left and right inspection cameras 5 and 6 are respectively positioned on the left and right sides of the conveying unit 1 and fixed to the left and right columns of the mounting bracket 2 via the third and fourth adjustment brackets 51 and 31, respectively. The third and fourth adjustment brackets have the same structure as the first adjustment bracket 31, including a fixed base, an adjustment rod, and a locking knob. The fixed base is bolted to the corresponding column, the adjustment rod is threaded to the fixed base, and the locking knob is used to lock the position of the adjustment rod. Both the left and right inspection cameras 5 and 6 are wide-angle industrial cameras, with their lens optical axes horizontally aligned with the conveying path of the conveying unit 1 to cover the complete area of ​​both sides of the medicine box, ensuring complete acquisition of traceability code information on both sides. The design of the third and fourth adjustment brackets allows for flexible adjustment of the camera position according to the actual size of the medicine box, thus adapting to the inspection needs of medicine boxes of different widths.

[0034] The front detection camera 7 and the rear detection camera 8 are respectively installed at the front and rear ends of the mounting bracket 2, and are fixed to the front and rear crossbeams of the mounting bracket 2 by the fifth adjustment bracket 71 and the sixth adjustment bracket 81. The structure of the fifth adjustment bracket 71 and the sixth adjustment bracket 81 is the same as that of the first adjustment bracket, including a fixed base, an adjustment rod, and a locking knob. The fixed base is fixed to the corresponding crossbeam by bolts, the adjustment rod is connected to the fixed base by threads, and the locking knob is used to lock the position of the adjustment rod. The design of the fifth adjustment bracket 71 and the sixth adjustment bracket 81 also allows for position adjustment according to the height or angle of the medicine box to ensure the acquisition quality of the images from both the front and rear sides.

[0035] Both the front detection camera 7 and the rear detection camera 8 are installed at an angle, with their lens optical axes at a set angle to the conveying path of the conveying unit 1, so as to cover the complete area of ​​the front and rear sides of the medicine box and ensure the complete collection of traceability code information on the front and rear sides.

[0036] The system also includes a central processing unit connected via data cables to the top detection camera 3, bottom detection camera 4, left detection camera 5, right detection camera 6, front detection camera 7, and rear detection camera 8 to receive image data collected by each camera. The central processing unit incorporates image processing algorithms to analyze and stitch the collected six-sided images, generating a complete six-sided image of the medicine box. The central processing unit also includes a traceability code recognition module and an information verification module. The traceability code recognition module extracts traceability code information from the stitched six-sided image of the medicine box, while the information verification module compares the extracted traceability code information with pre-stored information in the database to determine consistency. When the traceability code information verification fails, the central processing unit controls an alarm device to issue an audible and visual alarm signal, prompting the operator to intervene manually. For details, please refer to the existing literature described in the background section.

[0037] In actual operation, the medicine box is placed at the starting end of the conveying unit 1, and the drive mechanism of the conveying unit 1 drives the medicine box to move forward at a constant speed along the conveying path. The top detection camera 3, bottom detection camera 4, left detection camera 5, right detection camera 6, front detection camera 7, and rear detection camera 8 respectively acquire images of the top, bottom, left, right, front, and rear surfaces of the medicine box. The acquired image data is transmitted to the central processing unit via a data cable. The central processing unit stitches and analyzes the images, extracts the traceability code information from the six sides of the medicine box, and compares it with the pre-stored information in the database. If the traceability code information matches, the medicine box continues to move forward along the conveying path; if the traceability code information does not match, the central processing unit controls the alarm device to issue an audible and visual alarm signal. A rejection mechanism can be set up at the rear to reject the defective medicine box, or a sorting device 10 can be used to push the unqualified medicine box into the sorting channel through the action of a pusher cylinder.

[0038] The advantages of this utility model are that by setting detection cameras in six directions (up, down, left, right, front, and back) of the conveying unit, the omnidirectional visual detection of the six sides of the medicine box is realized, which solves the problem of missing traceability code information caused by the fixed installation position of the camera in the prior art.

[0039] The adjustable bracket design allows for flexible adjustment of the camera position, adapting to the testing needs of medicine boxes of different sizes and shapes, and improving the versatility and applicability of the device.
