Technical Field

[0001] The invention belongs to the technical field of library management, and in particular relates to a library book returning and arranging robot. Background Art

[0002] Library book return and arrangement refers to the process of placing scattered books returned by readers and reading them back to the corresponding positions on the bookshelf according to established classification rules and location requirements, and ensuring that they are arranged neatly and easy to find. This work is one of the core links in the daily management of the library. Its essence is to maintain the orderliness of book resources through systematic arrangement, so as to ensure that readers can efficiently obtain the required documents.

[0003] When returning books to their places on a daily basis, we often see library managers placing books with label numbers in designated areas. Sometimes they need to climb up to place the books, which is quite laborious. It takes a lot of time for the administrators to return and organize the books every day. For this reason, it is necessary to develop a robot that can replace the administrator to return the books, and at the same time can correctly return the books to the designated area and greatly improve work efficiency.

[0026] like Figure 1-6 The present invention relates to a library book returning and sorting robot, comprising a base 1, wherein electrically controlled walking wheels 2 are arranged around the bottom of the base 1, a rotating column 3 is arranged on the upper end of the base 1 for rotation through a bearing, a vertical plate 4 with a groove on one side is fixedly connected to the upper end of the rotating column 3, a rotating device 9 is arranged inside the base 1 and is dynamically connected to the rotating column 3, a lifting plate 5 is slidingly arranged in the vertical plate 4, and a placement groove 6 with an open outer side is fixedly connected to the end of the lifting plate 5, a slot 8 is arranged in the back side wall of the placement groove 6, and a slot 8 is symmetrically arranged in the placement groove 6. A book clamping device 11 is provided, a lifting adjustment device is provided in the vertical plate 4 and is power-connected to the lifting plate 5, and an identification and pushing device 12 is provided in the slot plate 7 to push the books arranged in the placement slot 6 to the book shelves of the library. The lifting adjustment device includes a motor 20, which is fixed to the upper end of the vertical plate 4. The output end of the motor 20 is connected to a screw rod 21 and is threadedly connected to the lifting plate 5. The height of the lifting plate 5 can be adjusted by the screw rod 21, so that books can be placed on bookshelves at different heights.

[0027] like Figure 1-4The identification and pushing device 12 includes a slider 13, which is slidably arranged in the slot plate 7. The end of the slot plate 7 is fixedly connected to a motor 2 15. The output end of the motor 2 15 is connected to a screw rod 2 14 and rotates inside the slot plate 7. The screw rod 2 14 is threadedly connected to the slider 13. An L-shaped sliding plate 16 is slidably arranged in the slider 13. A push plate 18 is fixed on the sliding plate 16 and can pass through the slot 8 horizontally. An electric push rod 17 is horizontally fixed on the slider 13. The output end of the electric push rod 17 is fixedly connected to the sliding plate 16. The extension direction of the electric push rod 17 is the same as the sliding direction of the sliding plate 16. A visual recognition camera 19 that can intelligently identify the data number is provided in the slot plate 7 and the push plate 18. The visual recognition camera 19 can intelligently identify the number of the bookshelf. At the same time, the visual recognition camera 19 on the push plate 18 can identify the book number in the placement slot 6 and make a judgment. Under the push of the push plate 18, the book is pushed from the placement slot 6 to the bookshelf.

[0028] like Figure 1 、 2 , 3, 4 and 6, the book clamping device 11 includes a clamping rod 25, the clamping rod 25 passes through the side wall of the placement groove 6, the end of the clamping rod 25 is fixed with a clamping plate 26 and is located in the placement groove 6, the clamping rod 25 is symmetrical on the clamping plate 26 and is provided with two groups of sliding rods 27 and passes through the side wall of the placement groove 6, a spring 28 is sleeved on the clamping rod 25, one end of the spring 28 is fixed to the clamping plate 26 and the other end is fixed to the side wall of the placement groove 6, the initial state of the spring 28 can meet the need for the clamping plates 26 on both sides to dock in the middle of the placement groove 6, the other end of the clamping rod 25 is fixed with an end plate 29, and the book can be clamped vertically in the placement groove 6 through the clamping plate 26 to prevent it from tipping over.

[0029] like Figure 4-5 The rotating device 9 includes a motor three 22, which is fixed to the inside of the base 1. The output end of the motor three 22 is connected to a gear one 23. The lower end of the rotating column 3 is fixed to a gear two 24 and meshes with the gear one 23. The rotating device 9 can realize the reversal of the opposing plate 4, thereby adjusting the direction and position of the bookshelf where the books are returned, which is more flexible.

[0030] like Figure 4 A control center 30 is provided inside the base 1. The control center 30 can be connected to the visual recognition camera 19 signal, and can control the movement of the wheel 2, and is connected to the motor 1 20, the motor 2 15 and the motor 3 22 electronic control signal.

[0031] During specific use, the books that need to be returned are stacked in the placement slot 6, and the books are clamped by the clamping plate 26 so that the books remain upright. The labels of the books are located on the back side, and the control center 30 controls the wheels 2 to move to the side of the bookshelf. First, the visual recognition camera 19 on the slot plate 7 will identify the bookshelf and number it. According to the identified number, the motor 20 will drive the screw rod 21 to rotate, and the screw rod 21 will drive the lifting plate 5 to rise and fall, so that the placement slot 6 is lifted to the height of the bookshelf that needs to be returned.

[0032] At this time, the motor 2 15 will drive the screw rod 2 14 to rotate, and the screw rod 2 14 will drive the slider 13 to slide in the groove plate 7, so that the push plate 18 will slide on the back side of the book, and the visual recognition camera 19 on the push plate 18 will search for the book number that needs to be returned until the push plate 18 is behind the book number that needs to be returned and then stops. The electric push rod 17 pushes the sliding plate 16 to slide in the slider 13, and the push plate 18 will push the book onto the bookshelf and return it. After returning to its place, the push plate 18 retreats, and under the action of the spring 28, the clamping plate 26 clamps the remaining books again until all the books are returned to their place.

[0033] When returning books to their original positions, the motor 3 22 can also be used to drive the gear 1 23 to rotate, the gear 1 23 engages the gear 2 24 to rotate, and the gear 2 24 drives the rotary column 3 to rotate, so that the placement slot 6 can be reversed and the bookshelf on the other side can be found.

[0034] The visual recognition camera in the present application can be replaced by RFID, and RFID tags can be set on books so that the robot can quickly locate them when scanning. This is a prior art and will not be described in detail.

[0035] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
