Description

Technical Field

[0001] This utility model relates to the field of QR code acquisition technology, and in particular to a continuous QR code label scanning and registration device. Background Technology

[0002] In today's logistics, manufacturing, retail, and many other industries, QR code labels are widely used as key information carriers. They are primarily used for tracking product information, managing inventory, and optimizing supply chain tracking, providing rapid and accurate data support to ensure transparency and efficiency at every stage. Once produced, QR code labels typically require initial registration via scanning to lay the foundation for subsequent product tracking and management. This process not only improves data entry accuracy but also effectively reduces human error and enhances overall work efficiency. Furthermore, the application of QR code labels enables precise tracking of every stage from production to sales, facilitating real-time monitoring of product flow and status, and timely response to market changes or handling of emergencies.

[0003] Patent CN212411204U discloses an intelligent barcode reading system. This patent includes a rectangular frame support placed on the ground, with a rotatable label roll mounted on its top right end. After the label is released from the roll, it first passes a left-turning point located on a first guide roller, which guides the label's direction. Subsequently, the label reaches a feeding roller, further ensuring its smooth progress until it reaches the barcode scanner, located to the left of the feeding roller for automatic QR code scanning. After scanning, the label continues to a second guide roller and is finally collected by a label take-up drum. The take-up drum's shaft is connected to a constant torque motor via a coupling, enabling automatic take-up. The entire process is precisely regulated by a PLC control system, ensuring that the label take-up speed and scanning operation are synchronized, greatly improving data entry accuracy, reducing labor costs, and increasing product qualification rates. However, in practical applications, this patent still has some shortcomings. The design of the label transmission path lacks effective limiting and leveling devices, which makes it easy for the label to deviate from the predetermined track during movement and may cause deformation such as edge folding. These problems not only hinder barcode scanning and recognition but also significantly affect the scanning and recognition efficiency, thereby reducing the overall work efficiency.

[0004] Therefore, there is an urgent need to provide continuous scanning and registration equipment for QR code labels that ensures the labels remain stable and flat throughout the entire transmission process. Utility Model Content

[0005] The purpose of this invention is to provide a continuous scanning and registration device for QR code labels that ensures the labels remain stable and flat throughout the entire transmission process. This overcomes the shortcomings of existing technologies where labels are prone to deviating from the track and deforming such as edge folding during transmission, which hinders scanning and recognition, significantly affects scanning efficiency, and thus reduces overall work efficiency.

[0006] The purpose of this utility model is achieved through the following technical solution: a continuous QR code label scanning and registration device, including a workbench, on which mounting frames are fixedly installed on both sides, and a motor is installed on each mounting frame. The output shaft of the motor is connected to a placement shaft via a key. A scanning device is installed on the workbench surface. Guide frames are provided on both sides of the workbench. Guide rollers are symmetrically distributed and fixedly connected to the guide frames. A pair of limiting sleeves are slidably arranged on each guide roller. A first screw is threaded through the limiting sleeve. A first guide rod is symmetrically distributed and fixedly connected to the limiting sleeve. A pressure block is slidably installed on the first guide rod. An elastic element is sleeved on the first guide rod. The two ends of the elastic element are respectively connected to the pressure block and the limiting sleeve. L-shaped support rods are fixedly connected to both sides of the guide frame. A second screw is rotatably arranged on one side of the L-shaped support rod, and a second guide rod is fixedly connected to the other side of the L-shaped support rod. A pressure rod is slidably arranged on the second guide rod. One end of the pressure rod can slide up and down along the second guide rod, and the other end is threadedly connected to the second screw.

[0007] Preferably, the bottom of the workbench is provided with symmetrically distributed guide rails, and a placement plate is slidably mounted on the guide rails. Square slots are provided at the four corners of the placement plate, and the same square slots are also provided on the front side of the guide rails. A locking rod is provided between the aligned square slots.

[0008] Preferably, the placement plate is provided with a heat dissipation mesh structure.

[0009] Preferably, the workbench has a storage area under the table surface, and a first cable management plate is arranged inside the storage area. A second cable management plate is arranged on the first cable management plate. The first cable management plate can be snapped together with the second cable management plate. Both the first and second cable management plates have multiple cable trays. Multiple protective sleeves are arranged on the front side of the first cable management plate, and the protective sleeves are aligned with the cable trays.

[0010] Preferably, the two adjacent left and right pressure blocks are connected by a connecting rod.

[0011] Preferably, the heat dissipation mesh structure of the placement plate is equipped with symmetrically distributed cooling fans.

[0012] Compared with the prior art, the advantages of this utility model are as follows: 1. First, by using the limiting sleeve to limit the two sides of the label, the label is prevented from shifting during movement, ensuring the consistency and accuracy of the label path. Then, by pressing the pressure block tightly against the surface of the guide roller, the edge folding or wrinkling of the label during movement is effectively prevented. Finally, through the cooperation of the pressure rod, the second screw and the second guide rod, the necessary tension can be provided for the label during transmission, ensuring the label is taut during transmission and avoiding slackness, thereby ensuring the flatness of the label and the stability of transmission.

[0013] 2. This device features a sliding placement plate, providing a stable platform for the computer connected to the device, making computer operation more convenient. In addition, a storage area is provided at the bottom of the device, equipped with a cable management board and protective sleeve, which helps to organize and protect the cables, saving space and avoiding potential risks caused by messy wiring. This design not only makes the device look neater, but also facilitates maintenance and management. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 5 The diagram shows an embodiment of the continuous QR code label scanning and registration device provided by this utility model. It includes a workbench 1, with mounting frames 101 fixedly installed on the left and right sides of the workbench 1. Each mounting frame 101 is equipped with a motor 102, and the output shaft of each motor 102 is connected to a placement shaft 103 via a key. The two placement shafts 103 are used to control the unwinding and rewinding of the labels, respectively. A scanning device 2 is installed on the surface of the workbench 1 to facilitate automatic identification of the QR codes on the labels. Guide frames 3 are provided on both sides of the workbench 1. A pair of guide rollers 301, symmetrically distributed on the left and right sides, are fixedly connected to the frame 3. Each guide roller 301 is slidably provided with a pair of limiting sleeves 4. A first screw 5 is threaded through the limiting sleeve 4. By rotating the first screw 5, it moves away from the guide roller 301, thereby releasing the fastening effect on the limiting sleeve 4, allowing the limiting sleeve 4 to slide freely on the guide roller 301. This allows for horizontal position adjustment along the guide roller 301 to accommodate labels of different sizes. Conversely, rotating the first screw 5 in the opposite direction causes it to gradually approach and eventually press against the guide roller 301. On the roller 301, due to friction and pressure, the position of the limiting sleeve 4 can be effectively locked. A first guide rod 7, symmetrically distributed vertically, is fixedly connected to the limiting sleeve 4. A pressure block 6 is slidably mounted on the first guide rod 7 to keep the label flat. Adjacent left and right pressure blocks 6 are connected by a connecting rod 19. The design of the connecting rod 19 allows the operator to simultaneously adjust the height of the pressure blocks 6 on both sides. An elastic element 8 is sleeved on the first guide rod 7, with both ends of the elastic element 8 connected to the pressure block 6 and the limiting sleeve 4 respectively, ensuring that the pressure block 6 can... The guide frame 3 is stably held in the required position. L-shaped support rods 12 are fixedly connected to both the front and rear sides. A second screw 13 is rotatably installed on one side of the L-shaped support rod 12, and a second guide rod 14 is fixedly connected to the other side of the L-shaped support rod 12. A pressure rod 15 is slidably installed on the second guide rod 14. One end of the pressure rod 15 can slide up and down along the second guide rod 14, and the other end is threadedly connected to the second screw 13. The height of the pressure rod 15 can be precisely adjusted by rotating the second screw 13 to accommodate labels of different thicknesses.

[0023] When using this device, first, the label roll is inserted into the left placement shaft 103 and the unwinding process begins. Then, the label head is pulled out so that it passes sequentially around the guide roller 301 and pressure bar 15 of the left guide frame 3. During this process, the limiting sleeve 4 is used to limit the label on both sides to prevent the label from shifting during movement, ensuring the consistency and accuracy of the label path. Then, by raising the pressure block 6 to an appropriate height and pressing the label tightly against the surface of the guide roller 301, the edges of the label are prevented from folding or wrinkling during movement. Since the label needs to pass under the pressure bar 15, the second screw 13 is rotated to move the pressure bar 15 up and down along the second guide rod 14 to a suitable position to contact the label. At this time, the pressure bar 15... A downward pressure is applied to the passing label, which must overcome this additional resistance as it continues to move forward, thus maintaining a certain tension and preventing slack. This ensures the label passes smoothly through the scanning area and facilitates subsequent winding operations. Next, the label head passes under the scanning device 2, then around the guide roller 301 and pressure bar 15 of the right guide frame 3, and is finally wound up by the right placement shaft 103. As the two motors 102 drive the placement shafts 103 on both sides to perform the unwinding and winding operations of the label, the label continues to pass under the scanning device 2 on the workbench 1. The device automatically and continuously scans the QR code information on each label and records it to the computer system.

[0024] Example 2: Based on Example 1, such as Figure 4 The workbench 1 has symmetrically distributed guide rails 9 on its bottom surface. A placement plate 11 is slidably mounted on the guide rails 9. The placement plate 11 provides a stable platform for the computer connected to this device. The placement plate 11 has a heat dissipation mesh structure to help dissipate heat from the computer. The heat dissipation mesh structure of the placement plate 11 is equipped with symmetrically distributed cooling fans 20. The cooling fans 20 effectively increase the airflow between the computer and the placement plate 11 and improve the heat dissipation efficiency. Square slots are provided at the four corners of the placement plate 11. The front side of the guide rails 9 also has the same square slots. The aligned square slots are provided with locking rods 10 for fixing the placement plate 11.

[0025] When this device is connected to a computer, first pull the placement plate 11 outward along the guide rail 9 to the appropriate position, ensuring that the square slot on the back of the placement plate 11 is precisely aligned with the square slot on the guide rail 9. Then, insert the locking rod 10 into the aligned square slot to securely lock the position of the placement plate 11. Subsequently, the operator can safely place the computer on the placement plate 11 for operation, making computer operation more convenient.

[0026] like Figure 6The workbench 1 has a storage area under its tabletop for storing external devices. The storage area is equipped with a first cable management board 16 and a second cable management board 17. The first cable management board 16 can be snapped into the second cable management board 17. Both the first cable management board 16 and the second cable management board 17 have nine cable slots for organizing and fixing wires. Nine protective sleeves 18 are provided on the front side of the first cable management board 16. The protective sleeves 18 are aligned with the cable slots to provide additional protection for the wires.

[0027] When this device is connected to the required external device, first place the external device in the storage area and remove the second cable management board 17. Then, place the wires connecting this device to the external device into the cable tray on the first cable management board 16 and pass them through the corresponding protective sleeve 18. After completing the wiring, reattach the second cable management board 17 to the first cable management board 16 to stabilize the position of the wires, ensure that the wires are neat and protected, and avoid damage or interference caused by external factors.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
