Description

Technical Field

[0001] This utility model relates to, specifically, an automated control logistics box barcode scanning device. Background Technology

[0002] Scanning barcodes on logistics boxes is a core component of modern logistics warehousing management. By scanning the barcodes on the logistics boxes, information tracking, efficiency improvement, and risk control can be achieved throughout the entire process of goods leaving the warehouse and being signed for at the final destination.

[0003] With the development of logistics in recent years, the shipment volume of logistics boxes has also increased. The traditional manual scanning method is inefficient. Automated scanning is carried out in conjunction with conveyor belts. However, the current automated scanning technology still requires manual assistance to face the logistics box in one direction for scanning, and it is prone to missed scans and inaccurate scanning. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automated control logistics box barcode scanning device, addressing the shortcomings mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an automated control logistics box scanning device, including a first conveyor belt structure and a second conveyor belt structure, with a gap between the first conveyor belt structure and the second conveyor belt structure, and a scanning room for scanning is provided on the outer side of the first conveyor belt structure and the second conveyor belt structure, with an inlet and an outlet at the front and rear of the scanning room to cooperate with the first conveyor belt structure and the second conveyor belt structure, and a maintenance door is provided on the outer side of the scanning room.

[0006] The first conveyor belt structure is provided with a pre-sensing structure on the outer side near the inlet. The pre-sensing structure includes a device frame, and visual recognition camera structures for aligning with the first conveyor belt structure and identifying tags are provided on both sides and the top of the device frame.

[0007] Furthermore, the bottom of the scanning room is equipped with a first barcode scanner aligned with the gap, and the top and four sides of the scanning room are equipped with second barcode scanners, which facilitates scanning operations from all six sides without blind spots.

[0008] Furthermore, the second barcode scanner is provided with a second supplementary light structure on its outer side, and the first and second transmission belt structures are provided with a first supplementary light structure at their ends to align the gaps, so as to facilitate supplementary lighting during barcode scanning.

[0009] Furthermore, the equipment rack is equipped with ranging array plates on both sides of the visual recognition camera structure, and the ranging array plates are equipped with multiple laser rangefinder structures to facilitate distance measurement operations.

[0010] Furthermore, an induction array plate is provided on the top of the scanning room in front of the gap, and multiple infrared sensor structures aligned with the first conveyor belt structure are provided at the bottom of the induction array plate to facilitate sensing the movement trajectory of the logistics box.

[0011] Furthermore, both the inlet and outlet are equipped with light-shielding strips to facilitate auxiliary light-shielding operations, thereby ensuring the internal lighting and scanning operations.

[0012] Compared with the prior art, the advantages of the automated control logistics box scanning device of this utility model are: no manual intervention required and high degree of automation: the label position is identified in advance by the pre-sensing structure and the logistics box trajectory is tracked by the induction array plate. With the coordinated work of the six-sided barcode scanner, there is no need to manually adjust the orientation of the logistics box throughout the process, which can realize "unmanned barcode scanning", reduce labor costs and improve process continuity.

[0013] No blind spots in barcode scanning, low missed scan rate: The first barcode scanner covers the bottom, and the second barcode scanner covers the top and four sides, achieving barcode scanning without blind spots on all six sides, which is suitable for logistics boxes with labels affixed to any position; and the control system can selectively activate the corresponding barcode scanner to avoid resource waste caused by "all barcode scanners working", and the missed scan rate can be reduced to below 0.1%.

[0014] High scanning accuracy and strong anti-interference ability: The light-blocking cloth structure isolates external light, and the light compensation structure of the supplementary light structure ensures stable lighting in the scanning room (brightness fluctuation ≤ ±5%); at the same time, the dual positioning of visual recognition and infrared trajectory tracking ensures that the scanner starts in the optimal position, and the scanning accuracy can reach more than 99.9%.

[0015] Highly adaptable and low energy consumption: The laser rangefinder structure (11) can identify logistics boxes of different sizes (width 20-80cm, height 15-60cm). The conveyor belt speed and scanning strategy can be dynamically adjusted to adapt to high throughput scenarios (1200-1500 logistics boxes can be processed per hour); and only the barcode scanner and fill light in the corresponding area are activated, which reduces energy consumption by 30-40% compared with existing devices.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1-3 An automated control logistics box scanning device includes a first conveyor belt structure 3 and a second conveyor belt structure 4. A gap 12 is provided between the first conveyor belt structure 3 and the second conveyor belt structure 4 to expose the bottom of the logistics box (for easy bottom scanning). The conveying speed of the two conveyor belts can be synchronously adjusted by the control system (default speed 0.5-1m / s, adaptable to logistics boxes of different sizes). A scanning chamber 1 for scanning is provided on the outer side of the first conveyor belt structure 3 and the second conveyor belt structure 4. The scanning chamber 1 has an inlet 5 and an outlet 6 at the front and rear to cooperate with the first conveyor belt structure 3 and the second conveyor belt structure 4. A maintenance door 7 is provided on the outer side of the scanning chamber 1.

[0022] The first conveyor belt structure 3 is provided with a pre-sensing structure 2 on the outer side near the inlet 5. The pre-sensing structure 2 includes a device frame 8, which is a "door" shaped frame that spans the first conveyor belt structure 3 to ensure that the logistics box can pass through the frame. The device frame 8 is provided with visual recognition camera structures 9 on both sides and the top for identifying labels by aligning with the first conveyor belt structure 3. There are 3 sets of visual recognition camera structures 9, which are respectively installed on the two side walls and the top of the device frame 8. The camera resolution is not less than 2 million pixels and can identify the position of barcode / QR code on the surface of the logistics box in real time.

[0023] The scanning room 1 is equipped with a first barcode scanner 13 at the bottom of the room, aligned with the gap 12. The scanning room 1 is also equipped with a second barcode scanner 15 on the top and four sides. There are a total of 5 second barcode scanners 15, one on the top of the scanning room 1 and four on the top of the four inner side walls. The scanning direction is diagonally downward (at an angle of 30-45° with the horizontal direction), which can cover the top, front, back, left and right sides of the logistics box. Together with the first barcode scanner 13, it can achieve "six-sided barcode scanning without dead angles". The control system can activate only the second barcode scanner 15 in the corresponding area based on the label position data transmitted by the visual recognition camera structure 9, thereby reducing energy consumption.

[0024] The second barcode scanner 15 is provided with a second supplementary light structure 16 on its outer side, and the first transmission belt structure 3 and the second transmission belt structure 4 are provided with a first supplementary light structure 14 at their ends with alignment gaps 12.

[0025] The equipment rack 8 is located on both sides of the visual recognition camera structure 9 and has a ranging array plate 10. The ranging array plate 10 is equipped with multiple laser rangefinder structures 11. Multiple laser rangefinder structures 11 are evenly distributed on each ranging array plate 10, which can measure the width, height and specific position of the logistics box on the conveyor belt.

[0026] The scanning room 1 has an induction array plate 17 located at the top of the room, in front of the gap 12. The bottom of the induction array plate 17 has multiple infrared sensor structures 18 aligned with the first conveyor belt structure 3. The induction array plate 17 is located at the top of the scanning room 1 (in front of the gap 12), and its bottom has multiple infrared sensor structures 18 evenly distributed. It can detect the movement trajectory (position, speed) of the logistics box on the first conveyor belt structure 3 in real time and feed the data back to the control system, ensuring that the scanner operates when the logistics box is in the optimal scanning position.

[0027] Both the inlet 5 and outlet 6 are equipped with light-blocking strip structures 19 on their inner sides. The dark-colored light-blocking fabric can block external light (such as sunlight and workshop lighting) from entering the barcode scanning room 1, avoid light interference that could reduce scanning accuracy, and maintain the stability of light inside the barcode scanning room 1.

[0028] This equipment also requires an external control system:

[0029] The control system is the core control unit of the entire device. It adopts a PLC controller and is electrically connected to the first conveyor belt structure 3, the second conveyor belt structure 4, the visual recognition camera structure 9, the laser rangefinder structure 11, the first barcode scanner 13, the second barcode scanner 15, the first supplementary light structure 14, the second supplementary light structure 16, and the infrared sensor structure 18. Its functions include: receiving detection data from each component, analyzing the label position and the logistics box trajectory, and controlling the collaborative work of each execution component (barcode scanner, supplementary light, and conveyor belt) to achieve a fully automated process of "pre-identification - trajectory tracking - accurate barcode scanning - delivery".

[0030] (II) Work Process

[0031] Logistics box delivery and pre-identification:

[0032] The logistics box is fed into the first conveyor belt structure 3 by an external conveyor. When the logistics box enters the "door"-shaped frame of the pre-sensing structure 2, the visual recognition camera structure 9 is activated, which takes pictures of the surface of the logistics box and identifies the label position (such as "bottom left" or "right middle"). The label coordinate data is transmitted to the control system. At the same time, the laser rangefinder structure 11 measures the width (e.g., 60cm), height (e.g., 40cm), and distance from the barcode scanning room 1 (e.g., 1m) of the logistics box. The data is synchronously fed back to the control system.

[0033] Entry into QR code rooms and trajectory tracking:

[0034] The logistics box moves towards the barcode scanning room 1 along with the first conveyor belt structure 3. When the infrared sensor structure 18 detects the front end of the logistics box, it sends a "track start" signal to the control system. The control system dynamically adjusts the speed of the first conveyor belt structure 3 based on the real-time data of the infrared sensor structure 18 (to ensure that the logistics box passes through the barcode scanning area at a uniform speed).

[0035] Precise barcode scanning and supplemental lighting:

[0036] When the logistics box moves above gap 12 (directly above the first barcode scanner 13), the control system uses the pre-identified label position data:

[0037] If the label is at the bottom, the first scanner 13 and the first supplementary light structure 14 are activated to complete the bottom scanning; (the logic here is that if the front pre-sensing structure 2 does not recognize the label, the control system assumes that the label is attached to the bottom).

[0038] If the label is in the middle of the right side, activate the second barcode scanner 15 and the corresponding second supplementary light structure 16 at the top of the right side wall to complete the right side barcode scanning;

[0039] After scanning is completed, the control system uploads the scanned data (such as the tracking number and cargo information) to the logistics management system and turns off the corresponding scanner and fill light.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
