Description

Technical Field

[0001] This application relates to the field of electronic tag detection technology, specifically to an automated information reading and writing device for NFC tags. Background Technology

[0002] Electronic tags are widely used in daily life due to their readability. Most tag reading and writing devices on the market are designed to handle large rolls of electronic tags, which typically have built-in RFID chips. Due to the characteristics of RFID chips, their read / write distance is relatively long, generally ranging from tens to hundreds of centimeters. This long read / write distance makes RFID tags very practical in scenarios requiring long-distance reading, such as logistics and warehousing, but it also results in a relatively loose overall structure and large size for use on large equipment such as gantry cranes.

[0003] In contrast, NFC tags have a shorter read / write distance, typically between 1 and 3 centimeters. This shorter distance makes NFC tags more suitable for scenarios requiring close-range contact reading, such as mobile payments and smart posters. Traditional RFID tag reading and writing devices are not suitable for reading and writing information from NFC tags.

[0004] In addition, traditional tag information reading and writing devices have some shortcomings, such as: they cannot accurately determine whether the reading and writing of each tag is successful, which may lead to low efficiency and increased error rate; they also cannot make precise position adjustments, resulting in low accuracy of reading and writing operations. Utility Model Content

[0018] The second reel includes a second reel body, and the outer wall of the second reel body is provided with a second mounting groove for mounting a second handle;

[0019] Both the first handle and the second handle have a "U" shaped structure, and both ends of the first handle and the second handle extend outward to form an extension plate for easy handling of the roll-shaped electronic tag tape; the outer walls of the first roll body and the second roll body are also provided with limiting blocks along the circumferential direction, and the inner wall of the roll-shaped electronic tag tape is in close contact with the outer wall of the limiting block.

[0025] Compared with the prior art, this application has at least the following beneficial effects:

[0026] 1. Based on further analysis and research of existing technical problems, this application provides an automated information reading and writing device suitable for NFC tags, including a housing. A main controller is installed inside the housing. Along the length of the front of the housing, an unwinding mechanism, a first guide roller assembly, a code reading device, a second guide roller assembly, and a winding mechanism are sequentially arranged, connected sequentially by a roll of electronic tag tape with an embedded NFC chip, forming a continuous conveying path. This application has a simple, compact, and small structure, and can be placed on a workbench, such as a desktop. Through the coordinated action of the various components, the tag tape can smoothly pass through each component, completing the automated information reading and writing operation. Simultaneously, a sensor is installed at the code reading device. When a tag is detected passing through, the sensor sends the signal to the main controller, which controls the motor's operation, thereby achieving automatic start and stop control for each tag's reading and writing. When a reading or writing operation is performed, the motor stops running; after reading or writing is completed, it automatically switches to the next tag, thus accurately determining the reading and writing operation of each tag.

[0027] 2. The barcode reader of this application is mounted on the front of the housing via a bracket. The top plate of the bracket has an elongated mounting hole, which allows the barcode reader to move horizontally within a certain range. At the same time, the barcode reader can also be manually fine-tuned in vertical position and fixed by upper and lower nuts to adapt to tags with different signal sensitivities, thereby further improving the reading and writing accuracy of each tag.

[0028] 3. The first and second reels of this application are respectively provided with a first handle and a second handle with a "U" structure, and both ends of the first handle and the second handle extend outward to form an extension plate. The outer walls of the first reel body and the second reel body are provided with limit blocks along the circumferential direction. This design improves the convenience and stability of operation. In particular, when replacing the reel that has been read and written, the design of the extension plate allows the user to easily remove or install the reel from the reel. The setting of the limit block can prevent the rolled electronic tag tape from moving back and forth during movement.

[0029] 4. In this application, the first upper guide roller, the first lower guide roller, the second upper guide roller, and the second lower guide roller are all provided with limit rings at the ends away from the machine housing. These rings are used to limit the roll of electronic tag tape, ensuring that the tag tape maintains a stable and accurate position during the conveying process, thereby improving the accuracy of the reading and writing operation and the reliability of the equipment.

[0048] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0049] One embodiment of this application, such as Figures 1-11 As shown, an automated information reading and writing device for NFC tags includes a housing 1. A main controller is housed inside the housing 1. Along the length of the front of the housing 1, an unwinding mechanism 2, a code reading device 3, and a winding mechanism 4 are arranged sequentially. The unwinding mechanism 2 is used to fix a roll of electronic tag tape 8. Each tag on the roll of electronic tag tape 8 has a built-in NFC chip. The code reading device 3 is used to read and write information from the electronic tags. The winding mechanism 4 is used to rewind the tag tape processed by the code reading device 3. A first guide roller assembly 5 is arranged between the unwinding mechanism 2 and the code reading device 3. After the unwinding mechanism 2, the first guide roller assembly 5 is used to guide the direction of the label tape, ensuring that the label tape can smoothly enter the barcode reader 3; between the winding mechanism 4 and the barcode reader 3, a second guide roller assembly 6 is provided, located after the barcode reader 3, to guide the direction of the label tape again, ensuring that the label tape can smoothly enter the winding mechanism 4; the unwinding mechanism 2, the first guide roller assembly 5, the barcode reader 3, the second guide roller assembly 6 and the winding mechanism 4 are connected in sequence through the roll-shaped electronic label tape 8 to form a continuous conveying path; the unwinding mechanism 2, the winding mechanism 4 and the barcode reader 3 are all connected to the main controller.

[0050] Preferably, the code reading device 3 has a built-in sensor that can detect the presence of the tag and trigger the read / write operation, and output a signal to the main controller, which then controls the motor to stop and start; of course, an external sensor can also be placed at the location of the code reading device 3 to detect the position of the tag.

[0051] The code reader 3 is mounted on the front of the housing 1 via a bracket 7, as shown below. Figure 7 As shown, the bracket 7 includes a top plate 71, two side plates 72 are symmetrically arranged on both sides of the bottom of the top plate 71, and the top plate 71 has a mounting hole 711 for mounting the code reading device 3 along the longitudinal direction.

[0052] More preferably, the mounting hole 711 is a strip-shaped hole; it also includes an upper nut 9 and a lower nut 10 located on the upper and lower parts of the top plate 71, respectively. The code reading device 3 is provided with threads on the outside, and the code reading device 3 is clamped on the bracket 7 by the upper nut 9 and the lower nut 10.

[0053] The code reader 3 (reader dock) has its own threads. When fixing it, it can be clamped onto the bracket 7 using two nuts (upper nut 9 and lower nut 10). The mounting hole 711 adopts a strip-shaped hole design, which is a long strip-shaped opening that provides a larger adjustment range, allowing the code reader 3 to move within a certain range. It can be finely adjusted in the height direction along the mounting hole 711, and also finely adjusted in the horizontal direction along its radial direction, so as to facilitate adjustment to the optimal signal position.

[0054] Preferably, the main controller is connected to a peripheral computer device, through which the device can be controlled.

[0055] Preferably, the outer surface of the housing 1 is also provided with an on / off switch, which is connected to the main controller and is used to start and stop the equipment; at the same time, the transmission start / stop, transmission speed and transmission direction of the equipment (unwinding mechanism 2 and winding mechanism 4) can also be adjusted through the computer equipment.

[0056] Preferably, the first guide roller assembly 5 includes a first upper guide roller 51 and a first lower guide roller 52 located at the lower right corner of the first upper guide roller 51. The first upper guide roller 51 and the first lower guide roller 52 are spaced apart in the horizontal direction and are arranged in an alternating manner in the vertical direction.

[0057] The second guide roller assembly 6 includes a second upper guide roller 61 and a second lower guide roller 62 located at the lower left corner of the second upper guide roller 61. The second upper guide roller 61 and the second lower guide roller 62 are spaced apart in the horizontal direction and are arranged in an alternating manner in the vertical direction. The first lower guide roller 52 and the second lower guide roller 62 are located at the same height.

[0058] More preferably, a limiting ring 511 is provided at the end of the first upper guide roller 51 away from the housing 1 to limit the roll of electronic tag tape 8.

[0059] Preferably, such as Figure 5 and Figure 6 As shown, the unwinding mechanism 2 includes a first reel 21 located outside the housing 1 and a first motor 22 located inside the housing 1. The first reel 21 is rotatably mounted on the housing 1, and the first motor 22 is connected to the main controller to drive the first reel 21 to rotate.

[0060] The winding mechanism 4 includes a second spool 41 located outside the housing 1 and a second motor 42 located inside the housing 1. The second spool 41 is rotatably mounted on the housing 1, and the second motor 42 is connected to the main controller to drive the second spool 41 to rotate.

[0061] More preferably, such as Figures 8-10As shown, the first reel 21 includes a first reel body 211, and the outer wall of the first reel body 211 is provided with a first mounting groove 213 for mounting a first handle 214; the first reel 21 also includes a second reel body 411, and the outer wall of the second reel body 411 is provided with a second mounting groove 413 for mounting a second handle 414.

[0062] Both the first handle 214 and the second handle 414 have a "U"-shaped structure, and the two ends of the first handle 214 and the second handle 414 extend outward to form corresponding extension plates 215, which facilitates the loading and unloading of the roll-shaped electronic tag tape 8. The outer walls of the first reel body 211 and the second reel body 411 are also provided with limit blocks 216 along the circumferential direction to prevent the roll-shaped electronic tag tape 8 from moving back and forth during movement. When the tag roll (roll-shaped electronic tag tape 8) is placed, the inner wall of the reel of the roll-shaped electronic tag tape 8 is tightly attached to the outer wall of the limit block 216 to achieve its fastening effect, thereby preventing the tag roll from moving back and forth during movement. When the tag roll is taken out, the handle is pulled outward with one hand, and with the assistance of the extension plate 215 at its end, the handle and the tag roll can be taken out as a whole. Then the handle is pushed inward to separate the handle from the tag roll. Finally, the handle is reinstalled on the reel body along the position of the mounting groove.

[0063] The first spool 21 also includes a first connecting plate 212 integrally formed with the first spool body 211. The first spool 21 also includes a second connecting plate 412 integrally formed with the second spool body 411. The first connecting plate 212 and the second connecting plate 412 are respectively provided with openings for placing the first handle 214 and the end extension plate 215 of the second handle 414.

[0064] Preferably, the bottom of the housing 1 is provided with a storage box, which can be a rectangular box, to store the power supply and communication cable connected to the code reading device 3.

[0065] The operating principle of the above embodiments:

[0066] The roll-shaped electronic tag tape 8 consists of a reel 81 and an electronic tag tape 82 wound on the reel 81. Before using this device, the roll-shaped electronic tag tape 8 needs to be installed and prepared according to the following steps: First, install the first reel 811 (main reel) with the built-in NFC electronic tag tape 82 on the outside of the first reel body 211; then, install the second reel 812 (secondary reel) on the outside of the second reel body 411; then manually unwrap and pull out the starting end of the NFC electronic tag tape wound on the first reel 811, passing through the first guide roller assembly 5, the code reader 3, and the second guide roller assembly 6 in sequence, and finally pull it onto the second reel 812 for pasting; wherein, the winding direction of the NFC electronic tag tape on the first guide roller assembly 5 and the second guide roller assembly 6 is as follows: Figure 11 As shown, the starting end of the NFC electronic tag first passes the bottom of the first upper guide roller 51 and the top of the first lower guide roller 52, then enters the top of the code reading device 3, then passes the top of the second lower guide roller 62 and the bottom of the second upper guide roller 61, and finally is pasted on the second reel 812.

[0067] After completing the above steps, the device can start operating. At this time, the roll-shaped electronic tag 8 with a built-in NFC chip is fixed on the unwinding mechanism 2. The electronic tag is powered by the winding mechanism 4. When the device starts, the second motor 42 drives the second reel 41 to wind clockwise. At this time, driven by the first motor 22, the electronic tag gradually unfolds from the first reel 21 of the unwinding mechanism 2, passes through the first guide roller assembly 5, and the first guide roller assembly 5 adjusts the direction of the tag to ensure that it can smoothly enter the code reading device 3. After the direction is adjusted by the first guide roller assembly 5, the tag... The tag tape enters the reading device 3. When the electronic tag tape reaches the reading dock position, the equipment automatically senses and stops winding. At the same time, the reading device 3 reads and writes information on the electronic tag on the electronic tag tape. After the reading device 3 completes the information reading and writing, the equipment automatically starts running. The electronic tag tape continues to move forward and passes through the second guide roller assembly 6. The second guide roller assembly 6 readjusts the direction of the tag tape to ensure that it can smoothly enter the winding mechanism 4. Finally, the entire electronic tag tape enters the winding mechanism 4, and the tag tape processed by the reading device 3 is re-wound to form a new roll of electronic tag tape 8.

[0068] After the read / write operation is completed, the NFC electronic tag tape that has completed the information read / write operation is completely wrapped around the outside of the second reel 812. When it is necessary to replace the new roll of electronic tag tape 8, the following operation is performed: pull the second handle 414 outward. Since the second handle 414 is provided with extension plates 215 at both ends, this will cause the second reel 812 and the wrapped NFC electronic tag tape to be pulled outward synchronously. Then, push the second handle 414 inward to separate it from the second reel 812 with the NFC electronic tag wrapped around it.

[0069] In summary, this application has at least the following advantages:

[0070] 1. The tags applicable to this application are tags with built-in NFC chips. The characteristic of this type of tag is that the working distance for reading and writing tag information is relatively short. Therefore, when using it, the reading device (reading and writing head) needs to be close to the tag. The overall structure is compact and small and can be placed on a desktop.

[0071] 2. The tags with built-in NFC chips contain a large amount of data such as user product information, anti-counterfeiting information, and traceability information. Therefore, it takes a long time to import information for a single tag. In order to ensure that each chip can import data correctly, a sensor is also set up at the code reader. When a tag is detected, it will send a signal to the main controller. The main controller controls the operation of the motor, thereby realizing automatic start and stop control of each tag reading and writing. The structure stops running during the reading and writing operation, and automatically switches to the next tag after the reading and writing is completed.

[0072] 3. To improve the accuracy of reading and writing each tag, this barcode reader can be manually fine-tuned in terms of its vertical position to accommodate tags with different signal sensitivities and improve the accuracy of reading and writing operations.

[0073] 4. The first and second reels are respectively equipped with a first handle and a second handle with a "U" shape, and both ends of the first and second handles extend outward to form an extension plate. The "U" shape and extension plate design make the operation more stable and convenient. Especially when replacing the reel that has been read and written, the extension plate design allows the user to easily remove or install the reel from the reel.

[0074] 5. Limiting rings are provided at the ends of the first upper guide roller, the first lower guide roller, the second upper guide roller, and the second lower guide roller that are away from the housing. These rings are used to limit the roll of electronic tag tape, ensuring that the roll of electronic tag tape maintains a stable and accurate position during transportation. This prevents the tag tape from shifting or twisting during transportation, thereby improving the accuracy of reading and writing operations and the reliability of the equipment.

[0075] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
