Description

Technical Field

[0001] This utility model relates to the field of tag detection technology, and more specifically to an RFID tag detection device. Background Technology

[0002] RFID tags, or Radio Frequency Identification tags, consist of a coupling element and a chip. Each tag has a unique electronic code. High-capacity RFID tags have user-writable storage space and are used to attach to objects to identify target objects; they are commonly known as electronic tags or smart tags. When a tag enters a magnetic field, it receives radio frequency signals emitted by a reader. Using the energy obtained from the induced current, it transmits the product information stored in the chip (passive tags) or actively transmits a signal at a specific frequency (active tags). The reader reads and decodes the information and sends it to a central information system for data processing.

[0003] For example, an RFID tag testing station with prior art publication number CN218471312U includes a frame. The frame is provided with an unwinding device, an RFID tag testing device, and a winding device in sequence along the tag forward direction. The RFID tag testing device includes a workbench and an RFID testing head set on the workbench. A metal sheet is set on the workbench at a position corresponding to the RFID testing head, which can be used to detect anti-metal RFID tags.

[0004] In existing systems, when materials are shipped out via conveyor belts, RFID tag detection devices are needed to identify the RFID tags on the material surface to improve shipping accuracy. The accuracy of the material information is then determined based on the identification information. However, general detection devices can only identify the tags and cannot detect surface defects. Furthermore, when tags peel off, manual pressing by workers is required for reinforcement, resulting in low production efficiency. Therefore, this invention provides an RFID tag detection device with detection, identification, and reinforcement functions. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides an RFID tag detection device. By integrating an industrial camera, an RFID reader / writer, and a pressing roller into a mounting plate, the three components work together to detect defects on the surface of RFID tags in real time and automatically acquire relevant data from the RFID tags, thereby improving the accuracy of the RFID tag data on the material. Furthermore, the pressing roller can press and reinforce the RFID tags, thereby improving the firmness of the RFID tags on the material surface and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an RFID tag detection device, including a mounting plate, an industrial camera, an RFID reader / writer, and a pressing assembly are arranged sequentially from front to back on the bottom of the mounting plate, the pressing assembly includes a mounting frame, a pressing roller is movably connected inside the mounting frame for pressing the RFID tag to increase its firmness, a first electric push rod is detachably connected to the top of the mounting frame, a sliding groove is provided on the rear side of the mounting plate, a slider is provided inside the sliding groove, the top end of the first electric push rod passes through the slider and extends out of the top of the slider, and fixing components are fixedly provided on both sides of the mounting plate.

[0007] In a preferred embodiment, a second electric push rod is detachably connected to the top of the industrial camera. The top of the second electric push rod passes through the mounting plate and extends beyond the top of the mounting plate. The height of the industrial camera is automatically adjusted by the second electric push rod to facilitate the use of materials of different heights.

[0008] In a preferred embodiment, a third electric push rod is connected to the front end of the slider, and a positioning groove adapted to the third electric push rod is provided on the top of the mounting plate. The third electric push rod is detachably installed in the positioning groove. The third electric push rod drives the slider to move back and forth in the groove, thereby enabling the pressing roller to press the RFID tag while moving back and forth, thus improving the pressing effect on the RFID tag.

[0009] In a preferred embodiment, the fixing assembly includes a fixing plate, and each of the two fixing plates has a movable groove on the side away from the mounting plate. An extension plate is provided in the movable groove, and a threaded rod is fixed to the top of each of the two extension plates. The threaded rod is fixed to the fixing plate by a nut. The operator can loosen the nut and then pull the extension plate to move it, thereby adjusting the length of the extension plate extending out of the movable groove, thus making it suitable for conveyor belts of different widths.

[0010] In a preferred embodiment, both fixing plates have multiple equally spaced fixing holes on their tops. The large number of fixing holes facilitates the use of bolts to fix the device, thereby improving the stability of the entire testing device.

[0011] In a preferred embodiment, the top of the mounting plate has multiple rectangular through holes, which are evenly distributed on the top of the mounting plate. The rectangular through holes on the mounting plate can reduce the weight of the mounting plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This invention integrates an industrial camera, an RFID reader, and a pressing roller into a mounting plate. The three components work together to detect defects on the surface of RFID tags in real time and automatically acquire relevant data from the RFID tags, thereby improving the accuracy of the RFID tag data on the material. Furthermore, the pressing roller can press and reinforce the RFID tags, thus improving the durability of the RFID tags on the material surface.

[0014] The height of the industrial camera is automatically adjusted by the second electric push rod, making it suitable for materials of different heights. The slider is driven by the third electric push rod to move back and forth in the chute, which allows the pressing roller to move back and forth while pressing the RFID tag, thereby improving the pressing effect on the RFID tag.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides an RFID tag detection device, including a mounting plate 1. From front to back, the bottom of the mounting plate 1 is provided with an industrial camera 2, an RFID reader / writer 3, and a pressing component 4. The industrial camera 2 is a key component in a machine vision system. The industrial camera 2 converts optical images into digital signals through a sensor (such as a CCD or CMOS sensor). When light shines on the sensor surface, photons interact with the semiconductor material to generate charges. The CCD sensor uses charge conduction to transfer electrical signals, while the CMOS sensor directly converts the charges into voltage signals. Finally, the analog signals are converted into digital signals by an analog-to-digital converter.

[0025] RFID reader 3 is a device that automatically identifies target objects and obtains relevant data through radio frequency identification signals. RFID reader 3 sends radio frequency signals of a specific frequency through an antenna as interrogation signals to detect whether there are RFID tags in the vicinity. When an RFID tag enters the communication range of the RFID reader, it will receive the signal. Passive tags rely on the radio wave energy sent by the RFID reader 3 to activate the internal circuit and then return the stored data to the RFID reader 3.

[0026] The pressing assembly 4 includes a mounting frame 41, and a pressing roller 42 is movably connected inside the mounting frame 41 for pressing the RFID tag to make it adhere more tightly to the material surface and increase the tag's firmness. A first electric push rod 43 is detachably connected to the top of the mounting frame 41. The motor on the first electric push rod 43 drives a pair of lead screw nuts after gear reduction, converting the motor's rotational motion into linear motion. The extension and retraction of the push rod are completed by the forward and reverse rotation of the motor. A sliding groove 44 is provided on the rear side of the mounting plate 1. A slider 45 is provided inside the sliding groove 44. The top end of the first electric push rod 43 passes through the slider 45 and extends out of the top of the slider 45.

[0027] Next, as Figure 2 As shown, fixing components 5 are fixed on both sides of the mounting plate 1. Specifically, the fixing components 5 include fixing plates 51. Each fixing plate 51 has a moving groove 52 on the side away from the mounting plate 1. An extension plate 53 is provided in the moving groove 52. A threaded rod 54 is fixed on the top of each extension plate 53. The threaded rod 54 is fixed to the fixing plate 51 by a nut. Each fixing plate 51 has multiple equally spaced fixing holes 9 on its top. The large number of fixing holes 9 makes it easy for workers to use bolts to fix the device, thereby improving the stability of the entire testing device.

[0028] In actual use, the staff first uses the fixing component 5 to install the mounting plate 1 above the conveyor belt. When the conveyor belt transports materials past the mounting plate 1, the industrial camera 2 takes pictures of the RFID tags on the surface of the materials and can quickly and accurately capture the image information of the RFID tags. Using image processing algorithms, defects on the surface of the RFID tags can be detected. Then, the RFID reader 3 automatically identifies the RFID tags and obtains relevant data through radio frequency identification signals, thereby improving the accuracy of the RFID tag data detection. When the materials pass under the pressing roller 42, the pressing roller 42 can press and reinforce the RFID tags, thereby improving the firmness of the RFID tags on the surface of the materials.

[0029] Refer to the instruction manual appendix Figures 1-5 The industrial camera 2 is detachably connected to a second electric push rod 6 at its top. The top end of the second electric push rod 6 passes through the mounting plate 1 and extends out of the top of the mounting plate 1. The height of the industrial camera 2 is automatically adjusted by the second electric push rod 6 to facilitate the use of materials of different heights.

[0030] like Figure 1 and Figure 2 As shown, the front end of the slider 45 is connected to a third electric push rod 7. The top of the mounting plate 1 is provided with a positioning groove 8 that is adapted to the third electric push rod 7. The third electric push rod 7 is detachably installed in the positioning groove 8. The third electric push rod 7 is used to drive the slider 45 to move back and forth in the slide groove 44, so that the pressing roller 42 can move back and forth while pressing the RFID tag, thereby improving the pressing effect on the RFID tag. The principle of the second electric push rod 6 and the third electric push rod 7 is the same as that of the first electric push rod 43, and will not be described here.

[0031] like Figure 1 As shown, the top of the mounting plate 1 has a rectangular through hole 10. There are multiple rectangular through holes 10, which are evenly distributed on the top of the mounting plate 1. Setting rectangular through holes 10 on the mounting plate 1 can reduce the weight of the mounting plate 1.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
