[0036] Specific Embodiment 1: Please refer to Figures 1-3 , the present invention provides a technical solution: an RFID scanning device for library management, including an RFID scanning mechanism 6, the RFID scanning mechanism 6 is installed at the end of the borrowing desk 1, the bottom of the borrowing desk 1 is covered with a support table 11, a rotating shaft 121 is movably installed in the middle of the support table 11 through a bearing, the top of the rotating shaft 121 is fixedly installed with the borrowing desk 1, a driving gear 13 is fixedly installed at one end of the rotating shaft 121 away from the borrowing desk 1, a book placement positioning ring groove 3 is formed on the surface of the borrowing desk 1, a limiting ring 2 is fixedly arranged outside the book placement positioning ring groove 3, and a card seat 4 is clamped and fixed on the limiting ring 2; four groups of support columns 16 are uniformly installed at the bottom of the support table 11, a frame 15 is screwed and installed at the bottom of the support table 11, and a driving motor 14 is screwed and installed on the frame 15.

[0037] Working principle: When in actual use, first place the book to be borrowed on the book borrowing table 1, and cover the RFID tag on the book directly above the book placement positioning ring groove 3. When a large number of books are neatly arranged on the book borrowing table 1, at this time, turn on the external switch of the drive motor 14. The output shaft of the drive motor 14 drives the driving gear 13 to rotate. The driving gear 13 drives the driven gear 12 to rotate slowly. The driven gear 12 drives the book borrowing table 1 to rotate slowly. When the book borrowing table 1 rotates, the three groups of guide blocks at its bottom are slidably arranged inside the guide groove 122. The cross-sections of the guide groove 122 and the guide blocks are both dovetail-shaped, which can limit and guide the rotating book borrowing table 1 to ensure the stability of the book borrowing table 1 during rotation and prevent it from tilting. At the same time, when the RFID tag on the book moves directly below the bottom of the RFID scanning gun 67, the RFID scanning gun 67 can scan the RFID tag at this time. The scanning gun sends a radio frequency signal with a specific frequency to the surrounding space, searches for RFID tags within its coverage area. When the RFID tag enters the radio frequency signal coverage area of the scanning gun, the antenna inside the tag will receive this signal and convert it into electrical energy to power the chip of the tag. After the chip is activated, it will send the book information stored in it in the form of a radio frequency signal through the tag antenna. After the antenna of the scanning gun receives the signal sent back by the RFID tag, it transmits it to the radio frequency module. The radio frequency module demodulates, decodes and processes the signal, and converts it into a digital signal that can be recognized by a computer. After receiving the digital signal, the control module further processes and analyzes it, extracts the book information contained in it, and displays this information on the display screen of the scanning gun, or transmits the data to the library management system through the interface to complete operations such as borrowing registration.

[0038] During the slow rotation of the book borrowing desk 1, a large number of books can be continuously scanned and borrowed. After the scanning of the books is completed, the books are moved out from the bottom of the RFID scanning gun 67, and then these books can be taken out. Unscanned books can be placed in this empty space to complete the continuous scanning of the books. In the traditional way, the staff needs to manually pick up each book for scanning, while the rotating workbench allows the staff to place multiple books on the workbench at one time. Through the rotating workbench, continuous scanning can be achieved without repeatedly picking up and placing books, greatly reducing the operation steps and saving time. The rotation speed of the workbench remains relatively stable and fast, enabling the RFID scanning gun 67 to quickly scan each book. Compared with manual scanning one by one, the speed is significantly improved, effectively alleviating the queuing pressure during the peak borrowing period. The rotating book borrowing desk 1 can provide a relatively stable placement platform for the books, ensuring a relatively stable distance and angle between the books and the RFID scanning gun 67, which is conducive to the scanning gun reading the RFID tag information more accurately and reducing problems such as repeated scanning or inaccurate data caused by incorrect reading. The continuous scanning can scan the books on the workbench one by one in a certain order, and it is not easy to miss any. Compared with manual scanning one by one, the staff may miss scanning a certain book due to negligence or other reasons. The continuous scanning method of the rotating workbench can effectively reduce this risk and ensure that each book can be accurately scanned and recorded. For readers borrowing a large number of books, there is no need to hand over the books to the staff one by one as before or scan them one by one themselves. They only need to place the books on the rotating workbench, which is more convenient and faster, reducing the cumbersome operations during the borrowing process and improving the convenience and fluency of borrowing. Due to the improvement of the scanning efficiency, the waiting time of readers when borrowing books is significantly shortened, and they can complete the borrowing process faster and leave the library, which is very important for readers with precious time and helps to improve the satisfaction of readers with the library service. The distance between the RFID scanning gun 67 and the book borrowing desk 1 can be adjusted by the servo electric cylinder 63 to adapt to the borrowing of thicker books in this way, and at the same time, the distance between the RFID scanning gun 67 and the RFID tag can be adjusted. Three groups of light strips 5 are arranged equidistantly from top to bottom. The light strip 5 is arranged in a ring shape and fixed on the limit ring 2 through the card rail 42 at the bottom of the card seat 4 to complete the installation of the light strip 5. The setting of the light strip 5 can illuminate the book borrowing desk 1 in the case of relatively dim light at night to ensure the normal progress of the book borrowing work on the book borrowing desk 1.
