Description

Technical Field

[0001] This utility model relates to the field of RFID scanning technology, and in particular to a foldable RFID handheld scanner. Background Technology

[0002] In the field of modern logistics and warehousing management, RFID tag scanning is a crucial step in achieving key functions such as cargo tracking and inventory management. Currently, the most commonly used device is the UHF handheld terminal, which integrates multiple reading and writing functions and is similar in size to a mobile phone for easy portability.

[0003] During scanning operations, operators need to hold a UHF handheld terminal, turn it on, and enter the corresponding read / write program. Based on the location of the RFID tag on the goods or shelf, the operator brings the terminal close to scan. The terminal emits electromagnetic waves through its antenna, activating the tag and receiving the returned information. Finally, the read data is stored or transmitted to the management system. This process is simple to operate, and the UHF handheld terminal, with its integrated design, large-capacity storage, and removable handle battery, ensures high efficiency and long battery life, making it suitable for diverse warehousing scenarios.

[0004] However, UHF handheld terminals face efficiency bottlenecks in central distribution warehouse operations. To prevent cross-reading, the power of the handheld terminals is reduced, requiring each label to be scanned individually. For example, when scanning 40 baskets (8 layers per pallet, 5 labels per layer), operators not only have to bend over frequently, increasing the risk of back injury, but also the time-consuming process of scanning each label individually makes it difficult to meet the high-efficiency operational needs of the central warehouse for rapid inventory counting and inbound / outbound operations, severely restricting the improvement of overall operational efficiency. Utility Model Content

[0005] Therefore, a foldable RFID handheld scanner is needed to solve the problem that scanning one by one takes a long time, which makes it difficult to meet the high-efficiency operation requirements of the central warehouse for rapid inventory and inbound / outbound operations of large quantities of goods, and seriously restricts the improvement of overall operation efficiency.

[0006] To achieve the above objectives, this utility model provides a foldable RFID handheld scanner, including a scanner body, multiple antenna modules, a read / write module, a power module, a smart terminal, and control buttons;

[0007] Multiple antenna modules are disposed at the front end of the scanner body and are all electrically connected to the read / write module for transmitting and receiving electrical signals. Two adjacent antenna modules are hinged to each other to form a foldable structure.

[0008] The read / write module is communicatively connected to the smart terminal. The antenna module, read / write module, smart terminal, and control button are all electrically connected to the power module. The control button is electrically connected to the smart terminal.

[0009] Furthermore, the antenna module has three sets, including one main antenna and two sub-antennas.

[0010] Furthermore, the main antenna is fixedly connected to the front end of the scanner body, and the other two secondary antennas are respectively hinged to both sides of the main antenna.

[0011] Furthermore, it also includes a gimbal, through which the antenna module is connected to the scanner body.

[0012] Furthermore, the front of the scanner body is provided with a retractable structure.

[0013] Furthermore, the smart terminal is detachably connected to the scanner body.

[0014] Furthermore, it also includes a bracket, which is disposed in the middle of the scanner body and is used to achieve a quick and detachable fixed connection with the smart terminal.

[0015] Furthermore, a handle is provided at the rear of the scanner body, and the control buttons are located at the handle; and / or the power module is located at the rear of the scanner body.

[0016] Furthermore, the read / write module and the smart terminal transmit data wirelessly.

[0017] Furthermore, the scanner body is made of carbon fiber.

[0018] Unlike existing technologies, the above-mentioned technical solution effectively solves the problems of short handheld handles and slow scanning compared to traditional scanners. Through the coordinated work of multiple foldable antenna modules, the reading and writing efficiency is improved, while reducing the labor intensity of operators and increasing work efficiency.

[0037] Please see Figures 1 to 7 This embodiment provides a foldable RFID handheld scanner, including a scanner body 10, multiple antenna modules 20, a read / write module 30, a power module 40, a smart terminal 50, and control buttons 60;

[0038] Multiple antenna modules 20 are disposed at the front end of the scanner body 10 and are all electrically connected to the read / write module 30 for transmitting and receiving electrical signals. Two adjacent antenna modules 20 are hinged to each other to form a foldable structure.

[0039] The read / write module 30 is communicatively connected to the smart terminal 50. The antenna module 20, the read / write module 30, the smart terminal 50, and the control button 60 are all electrically connected to the power module 40. The control button 60 is also electrically connected to the smart terminal 50.

[0040] The scanner body 10 supports, houses, or carries various functional components. Its shape can refer to the shell structure of existing RFID handheld scanners, and its material can be lightweight engineering plastic to ensure overall light weight and easy handheld operation. Multiple antenna modules 20 are located at the front end of the scanner body 10. Each antenna module 20 consists of an RFID antenna and a plastic panel encapsulating the antenna, and is electrically connected to the read / write module 30 to transmit and receive electrical signals. Adjacent antenna modules 20 are hinged together by hinges, which allow the antenna modules 20 to fold freely in the horizontal plane, forming a compact folding structure. In addition to hinges, various other hinge structures can be used, such as bearing hinges or loose-leaf hinges, to meet the needs of different scenarios. In the folded state, all antenna modules 20 can be stored at the front end of the scanner body 10 (located behind the main antenna module 201), leaving only one main antenna module 201 at the front for rapid scanning; alternatively, some antenna modules 20 can be unfolded according to actual needs to improve scanning efficiency.

[0041] The read / write module 30 is built into the scanner body 10 and communicates with the smart terminal 50 via a serial interface. It is responsible for controlling the antenna module 20 to transmit signals and decoding received signals. The smart terminal 50 can be a smartphone or a smart control screen, using an existing dedicated application to control the scanner and process and store data. The control buttons 60 are located on the handle 81 of the scanner body 10 for easy operation. They can be made of waterproof silicone, providing a good tactile feel and durability. They are electrically connected to the smart terminal 50 and are used to trigger scanning operations and control the scanner's power switch. The power module 40 uses a rechargeable lithium battery or dry cell battery and is installed at the rear of the scanner body 10, providing stable power support for the entire scanner.

[0042] In actual operation, the operator starts the scanner via control button 60. The smart terminal 50 sends instructions to the read / write module 30, which then controls the antenna module 20 to emit high-frequency electromagnetic wave signals. When the RFID tag enters the electromagnetic field range of the antenna module 20, the chip inside the tag is activated, transmitting the stored information back to the antenna module 20 in the form of radio waves. The read / write module 30 receives and decodes these signals, converting them into digital data which is then transmitted to the smart terminal 50 for processing and storage. By hinged multiple antenna modules 20, a folding function is achieved, significantly reducing the scanner's size when not in use, making it easy to carry and store. When in use, multiple antenna modules 20 can be quickly unfolded as needed, improving scanning efficiency. Compared to traditional scanners, this effectively solves the problems of a short handheld handle 81 and slow scanning speed. Through the collaborative work of multiple foldable antenna modules 20, reading and writing efficiency is improved, while simultaneously reducing the operator's workload and increasing operational efficiency.

[0043] Preferably, the antenna module 20 consists of three sets, including one main antenna 201 and two secondary antennas 202. This configuration ensures scanning efficiency while also balancing ease of handheld use. While an excessive number of antenna modules 20 could theoretically further improve scanning efficiency, it would actually increase the size and weight of the device, potentially causing operator fatigue during prolonged handheld use. Three sets of antenna modules 20 achieve a good balance between scanning efficiency and operability within a reasonable device size and weight range. In practical applications, the three antenna modules 20 work together to cover a wider scanning area, reduce blind spots, and significantly improve scanning efficiency, meeting the high-efficiency requirements for rapid inventory checks and warehousing in situations such as central warehouses.

[0044] Furthermore, the main antenna 201 is fixedly connected to the front end of the scanner body 10, and the other two auxiliary antennas 202 are respectively hinged to both sides of the main antenna 201. The main antenna 201 is fixedly installed at the front end of the scanner body 10, which can be fastened with bolts to ensure its stability and reliability during use. The two auxiliary antennas 202 are located on both sides of the main antenna 201 and are connected to the main antenna 201 by hinges, forming a flexible hinged structure. During scanning operations, the operator can easily unfold the auxiliary antennas 202 on both sides, so that the three antenna modules 20 are arranged in a fan shape or a straight line, thereby expanding the scanning range and improving scanning efficiency. When multiple antenna modules 20 are not needed, the auxiliary antennas 202 can be folded up to reduce the space occupied by the equipment and facilitate carrying and storage. This design improves the portability and flexibility of the equipment while ensuring scanning efficiency, adapting to the diverse needs of different scenarios.

[0045] In some embodiments, a gimbal 70 is also included, through which the antenna module 20 is connected to the scanner body 10. The gimbal 70 mainly consists of two mutually perpendicular rotating shafts and a connecting flange. The antenna module 20 is mounted on the connecting flange and can be freely adjusted in multiple directions via the rotating shafts. Its working principle utilizes the multi-directional rotation capability of the rotating shafts, allowing the antenna module 20 to flexibly change direction in space to adapt to different scanning needs. When used with the gimbal 70, operators can easily adjust the orientation of the antenna module 20 according to the actual situation to ensure optimal scanning angle and effect. This design is particularly suitable for scanning operations in complex environments, effectively improving scanning flexibility and accuracy, and further enhancing work efficiency.

[0046] In some embodiments, the front of the scanner body 10 is provided with a telescopic structure 80. Similar to a selfie stick, this telescopic structure consists of multiple interconnected tube sections. Each tube section is secured by spring clips, allowing the operator to adjust the length of the scanner body 10 by pressing the clips. Other existing telescopic rod structures can also be used, which will not be elaborated here. This telescopic structure effectively increases the scanner's length when scanning RFID tags at high or distant locations, avoiding frequent bending or tiptoeing by the operator and reducing fatigue. Simultaneously, the telescopic structure can be retracted to its shortest state when not in use, facilitating carrying and storage. Compared to traditional fixed-length handheld scanners, this telescopic structure effectively solves the problem of a short handheld handle 81, improving operational convenience and flexibility. It is particularly suitable for scanning racks with high standard stacking in warehouses, significantly improving operational efficiency and the operator's work experience.

[0047] In some embodiments, the smart terminal 50 is detachably connected to the scanner body 10. A common connection method is a magnetic connection, where the scanner body 10 has a magnetic interface and the back of the smart terminal 50 is equipped with a corresponding metal connecting plate. When the smart terminal 50 needs to be used, simply bring it close to the magnetic interface; the magnetism will automatically attract and fix the smart terminal 50, simultaneously establishing an electrical connection and ensuring stable data transmission. Another detachable connection method is a snap-fit ​​connection, where the scanner body 10 has a slot and the smart terminal 50 has snap-fits on both sides. By pressing the snap-fits, the smart terminal 50 can be easily installed or removed. This facilitates quick replacement of the smart terminal 50 according to different task requirements, improving the scanner's versatility and flexibility. Simultaneously, the detachable connection method allows the smart terminal 50 to be independently upgraded, maintained, or replaced, extending the scanner's lifespan and reducing operating costs. Furthermore, a bracket 82 is included, located in the middle of the scanner body 10, for quick and detachable fixed connection with the smart terminal 50. The bracket 82, installed in the middle of the scanner body 10, has various structural forms. A clamping bracket can be used, consisting of two opposing elastic clamping arms. The inner side of each arm has an anti-slip pad, allowing for quick and easy clamping of the smart terminal 50 in a designated position by adjusting the opening and closing of the arms. Alternatively, a suction cup structure can be used, with a vacuum suction cup at the bottom for attachment to the scanner body 10; an adjustable support arm at the top, with a clamp at the end for holding the smart terminal 50. This type of bracket enables rapid installation and removal of the smart terminal 50, allowing operators to quickly adjust its position and angle according to different work scenarios, further improving the scanner's ease of use and work efficiency.

[0048] In some embodiments, the scanner body 10 has a handle 81 at its rear, and the control button 60 is located on the handle 81. The handle 81 may have a grip structure with an anti-slip layer. Its surface is covered with a rubber anti-slip layer, which has a good coefficient of friction and a comfortable grip. It can effectively prevent slippage caused by sweaty or oily hands during operation, ensuring that the operator can hold the scanner stably. The control button 60 is located on the handle 81. When the operator holds the scanner, their fingers can naturally touch the control button 60, and they can perform operations such as scanning triggering and power switching without changing their grip posture. This conforms to operating habits, greatly facilitates one-handed operation, and improves work efficiency.

[0049] The power module 40 is located at the rear end of the scanner body 10. The battery compartment cover adopts a snap-on design for easy opening and battery replacement. This layout makes the replacement of the power module 40 simple and quick, without affecting other components of the scanner body 10 or occupying too much space, ensuring normal operation and rapid maintenance of the scanner.

[0050] Preferably, the read / write module 30 and the smart terminal 50 transmit data wirelessly. Multiple wireless communication protocols, such as Wi-Fi and Bluetooth, are supported. Taking Wi-Fi communication as an example, the read / write module 30 has a built-in Wi-Fi module. It modulates, demodulates, and decodes the data to be transmitted, converting it into electrical signals suitable for wireless transmission, which are then transmitted via an antenna. The Wi-Fi receiving module of the smart terminal 50 receives these signals, performs corresponding demodulation and decoding processing, and restores the original data. The principle of Bluetooth communication is similar to that of Wi-Fi. Wireless communication is convenient to install and simple to maintain, reducing malfunctions caused by cable damage or loose connections, and improving system reliability.

[0051] In some embodiments, the scanner body 10 is made of carbon fiber. Carbon fiber is a high-strength, low-density composite material, characterized by its light weight and high strength. Compared to traditional metal or plastic materials, the carbon fiber scanner body 10 can significantly reduce the overall weight while maintaining the structural strength of the device, making the scanner more portable. This is especially important for scanning tasks that require prolonged handheld operation, effectively reducing the operator's burden and improving work efficiency and experience.
