The movement of the slider 15 drives the barcode scanner 16 to move synchronously, so that the barcode scanner 16 reaches the specified position, and the barcode scanner 16 is accurately aligned with the barcode position of the book, ensuring the automatic entry of book information.
[0041] like Figure 1 and Fig.12 As shown, the third electric telescopic rod 30 is fixedly installed at the innermost position of the placement rack 11, and the diameter of the disc 24 is equal to the width of the push plate 23, ensuring that when the disc 24 rotates and drives the scraper 25 to rotate synchronously, the scraper 25 can contact the books. As the scraper 25 rotates, the rubber block 26 will be driven to slide along the surface of the book, effectively turning the book, and removing the dust and debris remaining inside the book, thereby improving the maintenance efficiency of the book.
[0042] Working principle: In actual use of the device, first go to the bookshelf to find the books that need to be borrowed, and remember the number of the storage bin 9 where the books are located, then go to the control panel 2, and two options will be displayed on the touch screen, namely, the options of borrowing books and returning books. Select the option of borrowing books, and the control panel 2 will prompt that the identity verification needs to be completed. Then you can choose to use the camera 3 for face recognition, the NFC card reader module 4 for mobile phone or card recognition, the fingerprint recognition module 5 for fingerprint recognition, or use the touch screen to enter a password to complete the identity verification. After the identity verification is completed, two options will pop up, namely, input the borrowing number and charge the mobile phone. When the mobile phone battery is low and needs to be charged, click the mobile phone charging option, and the first electric telescopic rod 6 will drive the control panel 2 to move outward as a whole. The movement of the control panel 2 drives the movable plate 71 to move synchronously inside the slide rail 72, and the movement of the movable plate 71 drives the T-shaped block 73 to move synchronously inside the slide groove. When the T-shaped block 73 reaches the end of the slide groove, the control panel 2 completes the movement, and then the mobile phone that needs to be charged can be placed in the mobile phone placement box 81. If the mobile phone has a wireless charging function, the mobile phone placement box The wireless charging module 82 inside 81 can charge the mobile phone. If the mobile phone does not have a wireless charging function, the USB to three-way cable plugged into the USB charging port 83 is used to charge the mobile phone. Then, click the mobile phone charging option again to return the control panel 2 to its original position. According to the same principle as above, the control panel 2 is driven to move inward as a whole to protect the mobile phone. Then, click the option to enter the borrowing number, and then enter the number of the placement bin 9 where the book is located. The second electric telescopic rod 10 will drive the placement rack 11 to move outward along the surface of the placement bin 9. When the placement rack 11 is completely pushed out, take out the book. Then, click the option to enter the borrowing number again. The second electric telescopic rod 10 will drive the placement rack 11 to move inward along the surface of the placement bin 9 back to its original position. At this time, borrowing is completed. Identity authentication can be completed through multiple methods such as face recognition, NFC card reading, fingerprint recognition or password input, so as to avoid affecting normal borrowing operations due to forgetting or losing the membership card, and facilitate users to charge and protect their mobile phones, as well as take and put operations of books, effectively improving the efficiency of book borrowing, and providing users with a fast, convenient, efficient and intelligent book borrowing experience.
[0043] Then when you need to return a book, click the option to return the book, and then an option to enter the book return number will pop up. Click and enter the number of the placement bin 9 where the book is located, and the second electric telescopic rod 10 will drive the placement rack 11 to move outward along the surface of the placement bin 9. When the placement rack 11 is completely pushed out, place the book's spine facing outward into the placement rack 11, and then click once to enter the option to return the book number. The second electric telescopic rod 10 will drive the placement rack 11 to move inward along the surface of the placement bin 9 back to its original position. At this time, the output chain end of the rigid chain telescopic mechanism 12 will drive the extrusion plate 13 to move toward the fixed block 14. As the extrusion plate 13 moves, the extrusion plate 13 will contact the book and squeeze the book to move. At the same time, the extrusion plate 13 will squeeze the cylinder piston rod 29, press the gas into the air chamber of the fixed block 14, and the gas enters the air chamber After the book is placed on the shelf 11, the air will squeeze the slider 15, causing the slider 15 to move along the air chamber. The movement of the slider 15 drives the barcode scanner 16 to move synchronously. When the squeezing plate 13 drives the book to completely fit the inner wall on the other side of the shelf 11, the gas will squeeze the slider 15 to reach the end of the air chamber. One end of the slider 15 will fit tightly against the moving plate 18 and apply a force to the moving plate 18. The moving plate 18 will simultaneously apply a force to the spring telescopic rod 17, causing the spring telescopic rod 17 to drive the moving plate 18 to move in the direction of the spring telescopic rod 17. At this time, the barcode scanner 16 is brought to the specified position by the slider 15, which can automatically realize the book reaching the specified barcode scanning position, and at the same time, the barcode scanner 16 is synchronously moved to the preset position, so as to realize accurate alignment with the book barcode for scanning, realize automatic entry of book information, simplify the book return process, and improve the book entry efficiency.
[0044] Then the third electric telescopic rod 30 is started, the third electric telescopic rod 30 drives the push plate 23 to move, the movement of the push plate 23 drives the gear 21 to move synchronously, so that the gear 21 rotates along one end surface 20 of the rack, the rotation of the gear 21 drives the linkage rod 22 to rotate synchronously, the rotation of the linkage rod 22 drives the disc 24 to rotate synchronously, the rotation of the disc 24 drives the scraper 25 to rotate synchronously, as the push plate 23 moves slowly, the push plate 23 will contact the book, as the scraper 25 rotates, the scraper 25 will drive the rubber block 26 to slide along the surface of the book, effectively turning the book, and removing the dust and debris remaining inside the book. Thereby, the maintenance efficiency of books is improved. When the push plate 23 drives the book to move so that the spine surface contacts the inner wall of the other end of the placement rack 11, the book position movement is completed. At this time, the barcode scanner 16 will identify and scan the barcode of the book. When the identification is completed, the first electric telescopic rod 6 will drive the control panel 2 to move outward as a whole. At this time, the mobile phone can be taken out. When the push plate 23 drives the book to move, the scraper 25 can realize synchronous rotation and drive the rubber block 26 to slide along the surface of the book, effectively turning the book, and removing the dust and debris remaining inside the book, thereby improving the maintenance efficiency of the book.
