Technical Field
[0001] This utility model relates to a QR code scanning and light-shielding device for cigarette storage, belonging to the field of cigarette storage technology. Background Technology
[0002] In the cigarette logistics and warehousing sector, QR code scanning technology has been widely applied to the inbound management process. After cigarettes are unloaded from trucks, they are transported to the warehouse via a conveyor line. On the conveyor line, QR code scanners scan the QR code information on the cigarettes, automating the inbound process. However, at the Qiandongnan Logistics Center, frequent instances of missed scans and false alarms occurred during the inbound QR code scanning process, leading to high downtime and low efficiency. Technical investigation revealed that these missed scans and false alarms were caused by ambient light interference triggering the QR code scanning sensors, resulting in erroneous scanning signals. This erroneous triggering not only causes unnecessary operational interruptions but also reduces inbound efficiency and increases manual verification costs. Utility Model Content

Detailed Implementation
[0010] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0011] Please see Figures 1 to 4 This embodiment provides a cigarette storage QR code scanning and light-shielding device, which includes a storage unit and a light-shielding unit.
[0012] The warehousing unit includes a conveyor line 11, a QR code scanner 12, and a sensor 13. Both the QR code scanner 12 and the sensor 13 are installed on the side of the conveyor line 11. When the sensor 13 detects a pack of cigarettes, the QR code scanner 12 starts scanning to identify the QR code information on the cigarettes.
[0013] The light-shielding unit includes a light-shielding cover 21 and a telescopic light-shielding curtain 22. The light-shielding cover 21 is mounted on the conveyor line 11 and houses the QR code scanner 12 and the sensing sensor 13. The light-shielding cover 21 has an inlet 211 and an outlet 212 corresponding to the upstream and downstream positions of the conveyor line 11. The telescopic light-shielding curtain 22 is installed on the upper part of the light-shielding cover 21 corresponding to the inlet 211. The light-shielding cover 21 reduces the influence of ambient light on the sensing sensor 13, and the telescopic light-shielding curtain 22 can further improve the light-shielding effect. Different telescopic states can be selected according to the actual ambient light conditions. In addition, the telescopic mechanism also facilitates the maintenance of the components inside the light-shielding cover 21.
[0014] For ease of operation, the light-blocking unit also includes an electric push rod 23 and a guide rod 24. Both the electric push rod 23 and the guide rod 24 are arranged horizontally. One end of the electric push rod 23 is installed on the upper inner side of the outlet 212 inside the light-blocking cover 21, and the other end of the electric push rod 23 is connected to the inner end of the telescopic light-blocking curtain 22. One end of the guide rod 24 is installed on the upper sides of the outlet 212 inside the light-blocking cover 21, and the other end of the guide rod 24 extends horizontally towards the inlet 211 of the light-blocking cover 21. The telescopic light-blocking curtain 22 includes a top baffle 221 and two side baffles 222. The side baffles 222 are installed on both sides of the top baffle 221, and the lower part of the side baffles 222 is movably sleeved on the guide rod 24. Thus, the telescopic blackout curtain 22 can be extended or retracted by the electric push rod 23. In the extended state, the telescopic blackout curtain 22 extends outside the inlet 211 of the blackout cover 21, which can increase the blackout effect and its extension length can be adjusted as needed. In the retracted state, the telescopic blackout curtain 22 is at least partially retracted inside the blackout cover 21.
[0015] For ease of operation, the light-shielding unit also includes an ambient light sensor 25. The ambient light sensor 25 is installed inside the light-shielding cover 21 near the sensing sensor 13 and is electrically connected to the controller. The controller is connected to the control terminal of the electric push rod 23. The controller uses an STM32F103 microcontroller and controls the action of the electric push rod 23 based on the detection value of the ambient light sensor 25. For example, when the detected ambient light intensity exceeds 30,000 lux, the controller controls the electric push rod 23 to unfold the telescopic light-shielding curtain 22 to the fully unfolded state; when the ambient light intensity is in the range of 10,000-30,000 lux, the controller controls the telescopic light-shielding curtain 22 to partially unfold; and when the ambient light intensity is less than 10,000 lux, the controller controls the telescopic light-shielding curtain 22 to retract into the light-shielding cover 21.
[0016] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
