Description

Technical Field

[0001] This utility model belongs to the technical field of RFID identification devices, specifically relating to an RFID identification device height adjustment device. Background Technology

[0002] With the rapid development of industries such as logistics, retail, and transportation, there is an urgent need for efficient object recognition technology. Traditional identification methods have limitations in terms of efficiency and accuracy. RFID identification devices use radio frequency signals to automatically identify target objects and acquire relevant data. This contactless process allows for the simultaneous identification of multiple tags, significantly improving identification speed and accuracy. RFID plays a crucial role in many fields, including modern inventory management, access control systems, and product tracking, and is an important technological device driving automation and intelligentization.

[0003] Traditional RFID identification devices typically have fixed antenna positions and lack adjustment mechanisms, which limits their vertical recognition range. For example, in a multi-tiered warehouse with varying shelf heights, a fixed-height antenna may not be effective at identifying tags on goods located at different shelf heights. Utility Model Content

[0004] The purpose of this invention is to provide a height adjustment device for an RFID identification device, in order to solve the problem that the antenna position of traditional RFID identification devices is usually fixed and lacks an adjustment structure, which limits the identification range in the height direction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an RFID identification device height adjustment device, including an outer box and a base disposed at the four corners of the lower side of the outer box;

[0006] An inner box is provided at the middle inner side of the outer box, and an adjustment motor is provided at the bottom upper left side of the outer box. A screw rod is provided on the upper side of the drive shaft of the adjustment motor.

[0007] A control cabinet is provided at the top inner side of the inner box, a sleeve is provided at the lower side of the control cabinet, multiple identification antenna boards are provided at the front side of the sleeve, a connecting frame is provided at the connection position between the sleeve and the multiple identification antenna boards, and a fixing plate is provided at the connection position between the bottom of the sleeve and the inner box.

[0008] A base plate is provided on the upper side of the regulating motor, and a sleeve rod is provided on the upper middle side of the base plate;

[0009] The control cabinet and the regulating motor are powered by connecting to an external power source.

[0010] Preferably, the base plate and the fixing plate are connected to the outer box and the inner box respectively by welding, and the sleeve rod is connected to the base plate by bolts.

[0011] Preferably, the sleeve is connected to the sleeve by a nested connection, and a helical hole for meshing connection is provided at the connection position between the helical rod and the fixed plate.

[0012] Preferably, sliders are provided on the inner walls of the left and right ends of the outer box, and a slide rail is provided at the connection position between the inner box and the sliders.

[0013] Preferably, the inner box can move up and down on the outer box slider via a slide rail, and the spiral rod is connected to the adjustment motor drive shaft by bolt connection.

[0014] Preferably, an observation window is provided at the upper front of the outer box, and an RFID IoT controller is provided inside the control cabinet.

[0015] 1. In practical applications, RFID tags may appear at different heights. For example, in warehouse management, goods are stacked at varying heights. With height adjustment functionality, the identification antenna plate can be adjusted according to the actual stacking height of the goods, ensuring more accurate identification whether the goods are placed on the bottom shelf or on higher shelves. This avoids blind spots caused by differences in tag height, greatly improving the flexibility of identification and enabling the device to adapt to various complex warehousing environments.

[0016] 2. When the height of the identification antenna plate is adjustable, it can be adjusted to a height close to that of the RFID tag to be identified. According to the principles of radio frequency identification (RFID), the distance and relative position between the identification antenna plate and the tag affect the strength and accuracy of the identification signal. Appropriate height adjustment allows for optimal signal transmission distance between the antenna plate and the tag, reducing signal attenuation and interference, thereby optimizing identification efficiency. For example, on a logistics conveyor belt, if the height of the identification antenna plate can be adjusted according to the size of the package and the tag position, RFID tag information on the package can be read quickly and accurately, accelerating package sorting and processing.

[0017] 3. This device can be applied not only to warehousing and logistics but also to retail stores, libraries, and other locations. In retail stores, goods are displayed on shelves at different heights; the height adjustment function ensures that the identification antenna plate can effectively identify tags on goods, whether displayed on the counter or at a higher level. In libraries, books are stored on bookshelves at different heights; by adjusting the height of the identification antenna plate, RFID tags on books can be easily identified for inventory management, borrowing registration, and other operations, enhancing the device's applicability in various scenarios.

[0018] 4. The height adjustment function makes equipment maintenance and upgrades more convenient. When maintaining internal components such as the identification antenna board or control cabinet, the inner box can be adjusted to a suitable height, making it easier for staff to perform inspections and parts replacements. For future technological upgrades, such as replacing the identification antenna board with a higher-performance one or upgrading the controller within the control cabinet, the height adjustment function can also easily adjust the equipment to a convenient operating position, reducing the difficulty and workload during equipment maintenance and upgrades.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] This utility model provides, for example Figure 1-6 The RFID identification device height adjustment device shown includes an outer box 2 and a base 4 disposed at the four corners of the lower side of the outer box 2;

[0028] An inner box 1 is located in the middle inner side of the outer box 2, and an adjustment motor 6 is located at the bottom upper left side of the outer box 2. A screw rod 8 is located on the upper side of the drive shaft of the adjustment motor 6.

[0029] A control cabinet 5 is provided at the top inner side of the inner box 1. A sleeve 11 is provided at the lower side of the control cabinet 5. Multiple identification antenna boards 10 are provided at the front side of the sleeve 11. A connecting frame 14 is provided at the connection position between the sleeve 11 and the multiple identification antenna boards 10. A fixing plate 12 is provided at the connection position between the bottom of the sleeve 11 and the inner box 1.

[0030] A base plate 7 is provided on the upper side of the adjusting motor 6, and a sleeve rod 9 is provided on the upper middle side of the base plate 7;

[0031] The control cabinet 5 and the regulating motor 6 are powered by connecting to an external power source.

[0032] An observation window 3 is provided on the upper front of the outer box 2, and an RFID IoT controller is provided on the inside of the control cabinet 5.

[0033] In this embodiment, the control cabinet 5 and the regulating motor 6 obtain electrical energy by connecting to an external power source to ensure that all parts of the device can work normally. The external power source provides the necessary power foundation for the operation of the device.

[0034] An RFID IoT controller is installed inside the control cabinet 5. This controller plays a core control role in the entire identification process. It can control and coordinate the relevant identification work of the identification antenna board 10, such as controlling the transmission and reception of identification signals, as well as processing and analyzing the received signals, to accurately identify target objects with RFID tags. It can also perform corresponding follow-up processing on the identified information or interact with external systems according to preset programs and rules.

[0035] The identification antenna board 10 is the component that directly performs the identification task. It is located on the front side of the sleeve 11 and is connected to the sleeve 11 via the connecting bracket 14. During operation, under the control of the RFID IoT controller, the identification antenna board 10 emits radio frequency signals of a specific frequency. When an RFID tag enters its signal coverage area, the tag is activated and reflects back a signal containing its own encoding and other information. The identification antenna board 10 then receives these reflected signals and transmits them back to the RFID IoT controller in the control cabinet 5 for further analysis and processing, thereby realizing the identification function of the target object.

[0036] An observation window 3 is provided on the upper front of the outer box 2. Staff can use the observation window 3 to visually view some of the operating status inside the device, such as whether the antenna board 10 is in normal working condition, so as to promptly detect any possible abnormalities and take appropriate measures.

[0037] like Figure 1-6 As shown, the base plate 7 and the fixing plate 12 are connected to the outer box 2 and the inner box 1 respectively by welding. The sleeve rod 9 is connected to the base plate 7 by bolting. The sleeve rod 9 is connected to the sleeve 11 by fitting. The spiral rod 8 and the fixing plate 12 are provided with a meshing spiral hole 16 at the connection position. The inner side of the outer box 2 is provided with sliders 15 on the inner left and right ends. The inner box 1 and the slider 15 are provided with a slide rail 13 at the connection position. The inner box 1 can move up and down on the slider 15 of the outer box 2 by the slide rail 13. The spiral rod 8 is connected to the drive shaft of the adjusting motor 6 by bolting.

[0038] Preferably, when height adjustment is required, the adjusting motor 6 starts working first. The adjusting motor 6 obtains electrical energy by connecting to an external power source, and its power is output through the drive shaft. Since the screw rod 8 is connected to the drive shaft of the adjusting motor 6 by bolts, the adjusting motor 6 can drive the screw rod 8 to rotate.

[0039] When the screw rod 8 rotates, because the screw rod 8 and the fixed plate 12 are connected by a meshing screw hole 16, the rotational motion of the screw rod 8 can be converted into the vertical linear motion of the fixed plate 12. At the same time, the sleeve rod 9 is connected to the sleeve 11 by a nesting connection, and the sleeve rod 9 is connected to the base plate 7 by a bolt connection. The base plate 7 is connected to the outer box 2 by a welding connection, and the fixed plate 12 is connected to the inner box 1 by a welding connection. This connection structure allows the inner box 1 to move up and down with the vertical movement of the fixed plate 12 under the guidance of the sleeve rod 9.

[0040] Slider blocks 15 are provided on the inner walls of the left and right sides of the outer box 2, and a slide rail 13 is provided at the connection between the inner box 1 and the slider 15. The inner box 1 can move up and down on the slider 15 of the outer box 2 via the slide rail 13. This structure plays an auxiliary guiding role in the up and down movement of the inner box 1, so that the inner box 1 can move up and down more smoothly during height adjustment, ensuring the accuracy and stability of the height adjustment of the inner box 1 part where the identification antenna board 10 is located.

[0041] As the inner box 1 moves up and down, the height of the identification antenna plate 10 also changes, thereby realizing the function of adjusting the height of the RFID identification device. The height of the identification antenna plate 10 can be adjusted according to actual needs to adapt to the identification requirements of RFID tags at different height positions.

[0042] 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.
