Description
Technical Field
[0001] This utility model relates to the field of cigarette production technology, specifically to a detection device for cigarette QR code association. Background Technology
[0002] my country's tobacco industry is actively promoting the "Unified Application of QR Codes in the Industry" project. The core objective of this project is to achieve full-process data collection for cigarette products in both industrial and commercial sectors, and to establish a precise correlation system for the three-tiered packaging of cigarette boxes, cartons, and individual cigarette cases. The application of QR codes on cigarette packaging needs to meet multiple technical standards: it must comply with the production processes and quality control requirements of tobacco companies, ensuring the printing quality and recognition effectiveness of the QR codes, while also achieving a systematic correlation of QR code information across the three levels of packaging. The establishment of this correlation mechanism not only helps companies achieve full-process traceability management of their products but also ensures that consumers can obtain accurate product information by scanning the codes.
[0003] The current industry-wide implementation of unified QR code application solutions has significant technical flaws, primarily in the lack of an automated system for verifying associated information. Existing quality control relies solely on manual sampling to scan and verify the associated information of QR codes on cigarette boxes, cigarette cartons, and cigarette cases on the production line. While this manual sampling method is suitable for quality monitoring based on samples, it cannot meet the need for full-volume inspection of cigarette products produced continuously every day. The main problem resulting from this is the difficulty in effectively preventing substandard products with abnormal QR code associations from entering the finished product warehouse. This not only affects the accuracy of data collection at the production site but may also pose risks to subsequent traceability management. Utility Model Content

[0028] The application of QR codes on cigarette packaging needs to meet multiple requirements. It must comply with the tobacco company's process quality standards to ensure effective printing, and it must link QR code information on cigarette packs, cartons, and individual cigarette cases so that companies can effectively track and trace products after they enter the market, and consumers can scan the codes to obtain accurate product information. However, existing unified QR code application implementation plans in the cigarette industry have shortcomings. They lack devices for automatically verifying the association information of QR codes on cigarette packs, cartons, and individual cases on the production line, relying solely on manual scanning. Manual scanning is suitable for spot checks, but it is difficult to scan each individual case of cigarettes continuously generated in daily production. This makes it impossible to effectively prevent unqualified products with unlinked QR codes on cigarette packs, cartons, and individual cases from entering the finished product warehouse, affecting the accuracy of the associated data at the work site.
[0029] This utility model provides a detection device for cigarette QR code association, which effectively solves the problem of unqualified products with abnormal QR code association entering the finished product warehouse and affecting the accuracy of association data at the work site.
[0030] Figure 1 This is a first schematic diagram of the structure of the detection device associated with the cigarette QR code provided by this utility model, as shown below. Figure 1 As shown, the detection device 100 associated with the cigarette QR code includes a cabinet 110, a transmission device 120, a photoelectric switch module 130, an inspection and code reading module 140, an industrial control module 150, and a PLC control module 160.
[0031] The upright cabinet 110 is located at the end of the cigarette packaging equipment, ensuring that cigarette packages can immediately enter the subsequent QR code detection and processing flow after the packaging process is completed. A conveyor device 120 is installed on one side of the upright cabinet 110. This device 120 is used to transport the packaged cigarette packaging, which can be a cigarette box, cigarette pack, or cigarette case. The conveyor device 120 employs advanced transmission technology and a stable structural design, possessing precise positioning and reliable transmission capabilities. It transports the packaged cigarette packaging from the packaging equipment to the relevant processing area of the upright cabinet 110 at a uniform and stable speed, ensuring that the cigarette packaging is not bumped, tilted, or damaged during transport, providing a good foundation for subsequent automatic QR code verification and other tasks.
[0032] In this embodiment of the present invention, the transmission device 120 includes a first transmission unit and a second transmission unit. The first transmission unit is connected to the end transmission device 120 of the cigarette packaging equipment and is used to receive cigarette packaging transmitted by the cigarette packaging equipment. The second transmission unit is used to receive cigarette packaging manually conveyed.
[0033] The first transmission unit is closely connected to the end transmission device 120 of the cigarette packaging equipment, seamlessly receiving cigarette packages stably transported from the packaging equipment. The second transmission unit provides a convenient cigarette packaging conveying solution for the manual cigarette box loading station. In some special inspection scenarios, manual participation in the addition and conveying of cigarette packages is essential. The second transmission unit can flexibly adapt to the characteristics of manual operation, allowing workers to quickly and accurately place cigarette packages on the transmission device 120.
[0034] Optionally, the first and second transmission units can automatically adjust the transmission speed according to the end transmission device 120 of the cigarette packaging equipment and the number of cigarette packages manually conveyed, thereby improving the efficiency and accuracy of manual operation, enhancing the adaptability of the entire testing equipment to different production conditions, and effectively avoiding testing interruptions and quality problems caused by mismatch between manual operation and automated processes.
[0035] The inspection and code reading module 140 is set on one side of the cabinet 110, and the photoelectric switch module 130 is set on the transmission device 120. The photoelectric switch module 130 is connected to the inspection and code reading module 140. When the cigarette packaging on the transmission device 120 passes the photoelectric switch module 130, the inspection and code reading module 140 is triggered to collect the QR code image of the cigarette packaging for recognition.
[0036] Optionally, the verification and reading module 140 includes at least two QR code readers, with at least one QR code reader respectively installed at one end of the first transmission unit and the second transmission unit. The photoelectric switch module 130 includes at least two photoelectric switches, with at least one photoelectric switch respectively installed on the first transmission unit and the second transmission unit. In this embodiment of the invention, the number of QR code readers and photoelectric switches can be flexibly configured according to the specifications of the cigarette packaging and the position of the QR code label sticker. For example, the first transmission unit is equipped with two QR code readers and two photoelectric switches for the arrival detection and QR code recognition of the cigarette packaging conveyed by the end transmission device 120 of the cigarette packaging equipment, and the second transmission unit is also equipped with two QR code readers and two photoelectric switches for the arrival detection and QR code recognition of the manually conveyed cigarette packaging.
[0037] In this embodiment of the invention, a photoelectric switch can be set at a preset trigger position in the first and second transmission units. When the cigarette package arrives at the trigger position, it enters the photoelectric signal coverage area. The photoelectric switch can sensitively detect the arrival of the cigarette package and quickly generate a signal to trigger the QR code reader to take a picture and identify it. Through this precise triggering mechanism, the cigarette package can be accurately located, effectively avoiding misreading and missed reading, and providing a solid guarantee for the QR code association detection, information management and quality traceability of cigarette packages.
[0038] The industrial control module 150 and the PLC control module 160 are installed inside the cabinet 110. The verification code reading module 140 is connected to the industrial control module 150, the industrial control module 150 is connected to the PLC control module 160, and the PLC control module 160 is connected to the transmission device 120. The verification code reading module 140 transmits the identification result to the industrial control module 150. The industrial control module 150 compares the identification result with the associated database and generates an associated verification result, which is then transmitted to the PLC control module 160. The PLC control module 160 controls the transmission device 120 to perform corresponding operations based on the associated verification result.
[0039] Optional, Figure 2 This is a second schematic diagram of the structure of the detection device associated with the cigarette QR code provided by this utility model, as shown below. Figure 2As shown, the detection device 100 associated with the cigarette QR code also includes an exchange device 170, which is installed inside the cabinet 110. The exchange device 170 is connected to the inspection code reading module 140 and the industrial control module 150 respectively. The exchange device 170 is also connected to the server network of the associated database to realize information sharing and read the existing associated data in the cigarette production process. At the same time, the verification status of this detection device can be remotely monitored through the data acquisition system.
[0040] In this embodiment of the invention, the industrial control module 150 can be an industrial computer, and the switching device 170 can be a switch. The industrial computer, PLC control module 160, inspection and code reading module 140, and switch together construct an efficient and accurate cigarette packaging QR code association detection management and control unit. The industrial computer and PLC control module 160 are closely connected to realize data interaction and command transmission. The inspection and code reading module 140 establishes a communication bridge with the industrial computer through the switch, which acts as a data relay station, ensuring that the QR code data collected by the inspection and code reading module 140 can be quickly and stably transmitted to the industrial computer. The industrial computer performs detailed analysis on the QR code data collected by the inspection and code reading module 140, comprehensively comparing the QR code data with the QR code association data in the factory's existing association database. If no matching information is found in the current association database, the industrial computer will quickly output an association anomaly signal to the PLC control module 160. Upon receiving an associated anomaly signal, the PLC control module 160 will immediately issue corresponding instructions. It can precisely control the transmission device 120 to perform a rejection operation, removing the problematic cigarette packaging from the device, or issue a stop signal to halt the entire transmission device 120, allowing staff to investigate the problem. Simultaneously, it can trigger an alarm to prominently remind staff to handle abnormal situations promptly, ensuring the safety and stability of the inspection process.
[0041] In this embodiment of the utility model, Figure 3 This is a third schematic diagram of the structure of the detection device associated with the cigarette QR code provided by this utility model, as shown below. Figure 3 As shown, the detection device 100 for cigarette QR code association may further include a display module 180, which is located on the front of the cabinet 110 and connected to the industrial control module 150. Optionally, the display module 180 can be an electronic display screen or a touch screen, capable of displaying images, on-duty statistical data, and current system and alarm settings. For example, multiple QR code readers only need one reader's QR code data to match the associated database for a successful association prompt to be displayed on the screen.
[0042] The detection device 100 associated with the cigarette QR code may also include an alarm module 190, which is located on one side of the cabinet 110 and connected to the industrial control module 150. The alarm module 190 may be an audible and visual alarm or a buzzer alarm, used to issue an alarm when QR code data verification fails.
[0043] The detection device 100 associated with the cigarette QR code may also include a debugging interface 200, which is embedded in one side of the cabinet 110. The debugging interface 200 is connected to the industrial control module 150 and is used to connect to external electronic devices for parameter debugging of the industrial control module 150. Optionally, the debugging interface 200 adopts an embedded design with a protective cover. The embedded design reduces contact with external contaminants, and the protective cover further seals and prevents dust, extending the debugging lifespan and reducing the risk of accidental contact, effectively improving operational safety. For example, the debugging interface 200 is used to connect to a laptop computer, allowing operators to intuitively see the QR code reader's photo-taking status, promptly identify and adjust problems, and flexibly configure QR code reader parameters to adapt to different detection scenarios.
