[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-6 The present invention provides a library robot, including a machine base 1, with electric wheels at the bottom of the machine base 1, and a top plate 12 connected to the top of the machine base 1 via four guide rods 11. A lifting seat 13 is slidably and vertically mounted on the guide rods 11, and a sliding seat 14 is slidably and horizontally mounted on the lifting seat 13. A storage and retrieval mechanism 3 is provided on the top of the sliding seat 14, and a stacking mechanism 2 is provided on one side of the storage and retrieval mechanism 3 on the top of the machine base 1.

[0023] The storage and retrieval mechanism 3 includes an electric push rod 31 fixed to the top of the translation seat 14. One side of the electric push rod 31 is connected to the slide table 32. The top of the slide table 32 is fixed with an electric push rod 34. One side of the electric push rod 34 is connected to the drive block 33. The top of the drive block 33 is rotatably mounted with a drive arm 35. The other end of the drive arm 35 is rotatably mounted on a connecting arm 36. One end of the connecting arm 36 is fixed with a clamping plate 39. The bottom of the drive arm 35 is fixed with a slider 37. The slider 37 slides in the opening block 38 fixed to the top of the slide table 32. Both the drive block 33 and the bottom of the slide table 32 are fixed with cuboid slide plates. The slide plates slide in the slide table 32 and the slide table 14. The slide table 14 has an open design at one end, that is, part of the slide plate at the bottom of the slide table 32 can be moved out of the slide table and located on one side of the translation seat 14.

[0024] As described above, through the design of the storage and retrieval mechanism 3, when performing book return and stacking operations, the books are first grouped together (i.e., books of the same type of bookshelf). Then, a selected group is placed on the stacking mechanism 2. At this point, the books are arranged on one side of the storage and retrieval mechanism 3. The machine base 1 moves to the bookshelf, and the electric push rod 31 is activated to move the slide 32, causing the two clamping plates 39 to move to the sides of a book, but not exceeding half the width of the book, i.e., not to the middle. Then, the electric push rod 34 is activated to displace the drive block 33, causing the drive arm 35 to rotate, and the slide 32... The book slides through the opening block 38, and the connecting arms 36 on both sides are pulled closer, so that the clamping plates 39 come close to hold the book. Then the lifting seat 13 rises, and after rising to the designated bookshelf layer position, the translation seat 14 translates, precisely moving the book to the designated position on that bookshelf layer. After that, the electric push rod 31 continues to extend, so that the two clamping plates 39 continue to move forward, moving the book into the stack of books. Note that some of the books are on the outside, so after stacking, the staff only needs to quickly push the books in by hand, which is very convenient.

[0025] A rubber pad 310 is bonded to the clamping surface of the clamping plate 39, and the surface of the rubber pad 310 is designed to be non-slip.

[0026] This design makes the clipboard 39 less likely to damage the book, and the anti-slip design increases friction, making it very practical.

[0027] The translation seat 14 is threaded through by a threaded rod 15, and the threaded rod 15 rotates on the support plates at both ends of the top of the machine base 1. A motor A16 that drives the threaded rod 15 to rotate is installed on the side wall of one of the support plates. A motor B19 is installed on the top of the top plate 12. The motor B19 is a dual-shaft design, and the two ends of the machine shaft are connected to two spools 18 installed on the top of the top plate 12. The spools 18 are designed to rotate and are driven by the machine shafts. The pull rope 17 wound on the spools 18 passes through the top surface of the support plate on the top plate 12 and is connected to the threaded rod 15. The translation seat 14 is equipped with several rows of ball bearings 111, and the ball bearings 111 roll in contact with the top surface of the machine base 1.

[0028] Through the above structural design, the translation and lifting functions are further refined. After the book needs to be lifted, the motor B19 is started to make the spool 18 rotate, so that the pull rope 17 winds around and pulls the lifting seat 13 to the designated bookshelf layer. Then the motor A16 is started to make the threaded rod 15 rotate. Due to the limitation of the ball bearing 111, the translation seat 14 cannot rotate but can only translate, which can move the book and the clamping plate 39 to the corresponding entry point, which is very convenient.

[0029] A silicone block 110 is fixed to the outer wall of the guide rod 11. The silicone block 110 is located below the lifting seat 13 and close to the machine base 1.

[0030] The silicone block 110 cushions the lowering seat 13 as it descends, meaning that the lowering seat 13 contacts the silicone block 110, thus effectively cushioning the descent.

[0031] The palletizing mechanism 2 includes a palletizing platform 21. The top of the palletizing platform 21 is provided with a row of "U"-shaped book slots 22. The top two ends of the palletizing platform 21 have handles 23, and the bottom two ends are fixed with inserts 24. The palletizing platform 21 is placed on the top of the machine base 1 and located on one side of the slide table 32. The inserts 24 are inserted into the top socket of the machine base 1.

[0032] With the design of the palletizing mechanism 2, during palletizing, books are inserted into the book slots 22 in sequence, and the handle 23 is held to place the palletizing platform 21 on top of the machine base 1. The insertion block 24 is inserted into the socket on the top of the machine base 1 to complete the installation. Since the types of books on different areas, i.e. different bookshelves, are mostly different and their thicknesses are also different, a palletizing mechanism 2 of a certain specification can be selected. Moreover, the specifications of the book slots 22 on different types of mechanisms are different, which improves the applicability.

[0033] A smart reader 4 is installed on the side of the slide table 32 facing the palletizing table 21. The back of the book or the place where the book is placed on the bookshelf is marked with a label corresponding to the smart reader 4. When the smart reader 4 recognizes the book label, it can automatically move the machine base 1 to the bookshelf where the book is located and lift the book to the height of the shelf for placement. This is an existing design method. The smart processor, analyzer or battery, etc. are all conventional robot settings and can be set at the bottom of the machine base 1, etc. (not shown in the figure), which will not be described in detail here.

[0034] Working principle: First, books are inserted into the book slots 22 one by one. Holding the handle 23, the palletizing table 21 is positioned on top of the machine base 1. The insert blocks 24 are then inserted into the top slots of the machine base 1. These books are located on different levels of the same bookshelf. The machine base 1 then moves the books to the desired shelf position. At this point, the clamping plate 39 is positioned at the outermost book. When the intelligent reader 4 recognizes the book label, it activates the electric push rod 31, which moves the slide table 32, causing the two clamping plates 39 to move to the sides of a book, not exceeding half the book's width (not to the middle). Then, the electric push rod 34 is activated, displacing the drive block 33 and rotating the drive arm 35. This causes the slide table 32 to slide in the opening block 38, pulling the connecting arms 36 closer together, bringing the clamping plates 39 closer to grip the book. The robot's built-in analysis system and processor will then... The process involves data analysis, which uses motor B19, spool 18, and pull rope 17 to raise the lifting platform 13 to the designated shelf level. Then, threaded rod 15 drives the translation platform 14 to move horizontally. The system and processor precisely move the books to the designated position on the shelf with the same label. Afterward, electric push rod 31 extends, causing two clamping plates 39 to move forward, placing the books into the stack. Note that some books are on the outside; after stacking, staff can quickly push them in by hand, which is very convenient. The clamping plates then return to the position of the book adjacent to the one previously retrieved. After stacking, the process is repeated for other shelves, eliminating the need for manual placement in large libraries. Note that the first shelf level does not need to be raised.
