[0015] A method for using an intelligent pick-and-place device for library book management comprises the following steps:

[0016] S1. Starting the first motor can drive the first shaft to rotate, and the rotation of the first shaft can drive the first gear to rotate. When the first gear rotates, it can drive the bracket and the moving plate to move by meshing with the first tooth plate. The moving plate moves along the first slide rail through the connection of the first slider. After the lifting frame is moved to the side position of the bookshelf by the displacement of the moving plate, the lifting frame can be driven to move down to the height where books need to be taken and placed through the operation of the multi-stage electric telescopic rod;

[0017] S2. After the lifting frame moves to the pick-up and placement working height, the second motor is started to drive the screw to rotate. When the screw rotates, the side plate can be driven to follow the movement through the connection with the first drive seat. The movement of the side plate is supported by the arrangement of the cross bar and the second drive seat. Through the movement of the side plate, the two side frames can be driven to follow and adjust their positions;

[0018] S3. According to the thickness of the book, the distance between the two side frames is adjusted. The third motor is started to drive the second shaft to rotate. The rotation of the second shaft drives the second gear to rotate. When the second gear rotates, the two second gear plates are meshed with each other, and the side frames are driven to move relative to each other. At this time, the side frames on both sides have completed the position adjustment according to the thickness of the book.

[0019] S4. After the hydraulic rod is started to extend, the side frame can be driven to move toward the bookshelf. At this time, through the setting of two inclined blocks, the inclined blocks can be inserted from the gaps on both sides of the books. As the side frame continues to move, the inclined blocks push the books on both sides open. The two inclined blocks move to the positions on both sides of the books. As the hydraulic rod continues to operate, the side frame is pushed to move. The two side frames are fully inserted from the gaps of the books. After the side frame is moved into place, the electric push rod is started to extend. The electric push rod can drive the push block to move toward the clamping plate. At this time, the inclined surface of the push block contacts the clamping plate, and the push block can push the clamping plate toward the book. After the electric push rod is fully extended and maintained, the clamping plates on both sides complete the clamping of the books. At this time, the hydraulic rod is started to contract to drive the side frame to move out of the bookshelf.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the inclined blocks can push open the books on both sides, and the two inclined blocks are moved to the positions on both sides of the books. As the hydraulic rod continues to operate, the side frames are pushed to move, and the two side frames are completely inserted from the book gaps. After the side frames are completely inserted into the book gaps, the electric push rod can drive the push block to move toward the clamping plate. At this time, the inclined surface of the push block contacts the clamping plate, and the push block can push the clamping plate toward the book. After the electric push rod is fully extended and maintained, the clamping plates on both sides complete the clamping of the book. At this time, the hydraulic rod is started to contract, and the side frames can be driven out of the bookshelf. The side frames maintain the clamping state of the books, and the book clamping operation is completed. For the book clamping operation, the books can be inserted into the gaps on both sides of the books when the books are neatly placed, and the book clamps can be taken out, which effectively improves the functionality of the equipment.

[0022] 2. In the present invention, when the books are initially inserted and clamped, the balls protruding from the outer side of the side frame can provide support, so that the books on the side contact with the balls. The rolling of the balls can reduce friction, thus avoiding damage to the books during the process of taking and placing the books, and providing better protection for the collection of books.

[0023] 3. In the present invention, the operation of the multi-stage electric telescopic rod can drive the lifting frame to move down to the height where books need to be picked up and placed. After the lifting frame moves to the picking and placing working height, the image of the books on the bookshelf can be captured by using two cameras. At this time, the position of the side frame is adjusted according to the image, so that the side frame moves to the position where books need to be picked up and placed.

[0039] The use steps of the present invention are as follows: when the intelligent pick-and-place device for library book management is used, multiple groups of bookshelves 102 are used, and multiple groups of bookshelves 102 arranged horizontally provide book placement. By using the displacement component 2, the displacement component 2 can drive the driving component 3 and the pick-and-place component 4 to follow the displacement. The driving component 3 and the pick-and-place component 4 can move to the position of any bookshelf 102 to perform pick-and-place operations on the books. A single pick-and-place device can be adapted to multiple groups of bookshelves 102 for use, thereby improving the pick-and-place efficiency of book management, thereby improving the organization and management efficiency of books. At the same time, when the device is not in use, it can be completely located above the bookshelf 102, occupying less space in the library. Starting the first motor 208 can drive the first rotating shaft 209 The first gear 210 can be driven to rotate with the first rotating shaft 209. When the first gear 210 rotates, it can drive the bracket 207 and the movable plate 205 to move with the first gear plate 203. The movable plate 205 moves along the first slide rail 202 through the connection of the first slider 204, that is, the first slide rail 202 and the first slider 204 cooperate to support and limit the displacement of the movable plate 205. After the lifting frame 301 is driven to move to the side position of the bookshelf 102 by the displacement of the movable plate 205, the lifting frame 301 can be driven to move down to the height where books need to be taken and placed through the operation of the multi-stage electric telescopic rod 206. Starting the second motor 302 can drive the screw rod 303 to rotate. When the screw rod 303 rotates, the side plate 401 can be driven to follow the movement through the connection with the first driving seat 305. The movement of the side plate 401 is supported by the arrangement of the cross bar 304 and the second driving seat 306. The movement of the side plate 401 can drive the two side frames 412 to follow the position adjustment. After the side frames 412 are moved to the positions on both sides of the corresponding books, the third motor 406 is started to drive the two second tooth plates 424 to move relative to each other. The movement of the second tooth plates 424 can drive the side frames 412 to follow the movement. When the side frames 412 move, they will be displaced along the second slide rail 409 through the connection with the second slider 411. That is, the displacement of the side frames 412 is played by the coordinated use of the second slide rail 409 and the second slider 411. The support and limit function is realized. At this time, the side frames 412 on both sides have completed the position adjustment according to the thickness of the books. The hydraulic rod 402 is started to clamp the books. After the hydraulic rod 402 is started and extended, the side frames 412 can be driven to move toward the bookshelf 102. At this time, through the setting of the two inclined blocks 414, the inclined blocks 414 can be inserted from the gaps on both sides of the books. As the side frames 412 continue to move, the inclined blocks 414 push the books on both sides open. The two inclined blocks 414 move to the positions on both sides of the books. As the hydraulic rod 402 continues to operate, the side frames 412 are pushed to move. The two side frames 412 are completely inserted from the gaps in the books. After the side frames 412 are completely inserted into the gaps in the books, the electric push rod 422 can drive the push block 423 to move toward the clamping plate 419.At this time, the inclined surface of the push block 423 contacts the clamping plate 419, and the push block 423 can push the clamping plate 419 toward the book. After the electric push rod 422 is fully extended and maintained, the clamping plates 419 on both sides complete the clamping of the book. At this time, the hydraulic rod 402 is activated to contract, which can drive the side frame 412 to move out of the bookshelf 102. The side frame 412 maintains the clamping state of the book, and the book clamping operation is completed. For the book clamping operation, the book can be inserted into the gap on both sides of the book when the book is neatly placed, which effectively improves the functionality of the device.

[0040] Embodiment 2: Figure 6-Figure 11 As shown, the inner surface of the side frame 412 is rotatably connected to two rollers 413, the inner surface of the side frame 412 is fixedly connected to an inclined block 414, the inclined block 414 is located outside the rollers 413, and the outer surface of the side frame 412 is provided with a plurality of circular holes, and balls 415 are arranged inside the plurality of circular holes.

[0041] The steps of using the present invention are as follows: during initial insertion, the protruding balls 415 on the outside of the side frame 412 can provide support, so that the books on the side are in contact with the balls 415. The rolling of the balls 415 can reduce friction, avoiding damage to the books during the process of taking and placing the books, thereby providing better protection for the book collection.

[0042] Embodiment 3: Fig.10 As shown, the outer surface of the other side of the fixing plate 404 is symmetrically fixedly connected with the second slide rails 409 , and the centers of the outer surfaces of the two second slide rails 409 are fixedly connected with cameras 410 .

[0043] The use steps of the present invention are as follows: the operation of the multi-stage electric telescopic rod 206 can drive the lifting frame 301 to move down to the height where books need to be picked up and placed; after the lifting frame 301 moves to the picking and placing working height, the two cameras 410 can be used to capture images of books at the position of the bookshelf 102; at this time, the position of the side frame 412 is adjusted according to the image, so that the side frame 412 moves to the position where books need to be picked up and placed.

[0044] The effect and working principle achieved by the entire mechanism are as follows: when the intelligent pick-and-place device for library book management is used, multiple groups of bookshelves 102 are used, and multiple groups of horizontally arranged bookshelves 102 provide for the placement of books. By using the displacement component 2, the displacement component 2 can drive the driving component 3 and the pick-and-place component 4 to follow the displacement, and the driving component 3 and the pick-and-place component 4 can move to the position of any bookshelf 102 to perform pick-and-place operations on the books. A single pick-and-place device can be adapted to multiple groups of bookshelves 102 for use, thereby improving the pick-and-place efficiency of book management, thereby improving the organization and management efficiency of books. At the same time, when the device is not in use, it can be completely located above the bookshelf 102, occupying less space in the library, and adjusting the driving component 3 and the pick-and-place component 4 to adjust the storage space. When the first gear 210 is rotated, the bracket 207 and the movable plate 205 can be driven to move along by the meshing with the first toothed plate 203. The movable plate 205 moves along the first slide rail 202 through the connection with the first slider 204. That is, the first slide rail 202 and the first slider 204 cooperate to support and limit the displacement of the movable plate 205. After the lifting frame 301 is driven to move to the side position of the bookshelf 102 by the displacement of the movable plate 205, the lifting frame 301 can be driven to move down to the position where the lifting frame 301 needs to be removed by the operation of the multi-stage electric telescopic rod 206. The height at which the books are placed, after the lifting frame 301 moves to the working height for taking and placing, the two cameras 410 can be used to capture the image of the books at the position of the bookshelf 102, and the position of the side frame 412 is adjusted according to the image, so that the side frame 412 moves to the position where the books need to be taken and placed, and the second motor 302 is started to drive the screw rod 303 to rotate, and when the screw rod 303 rotates, it can drive the side plate 401 to follow the movement through the connection with the first drive seat 305, and the movement of the side plate 401 is supported by the arrangement of the cross bar 304 and the second drive seat 306. Through the movement of the side plate 401, the two side frames 412 can be driven to follow and adjust the position, and after the side frames 412 are moved to the positions on both sides of the corresponding books, according to the thickness of the books, The spacing between the two side frames 412 is adjusted. Starting the third motor 406 can drive the second shaft 407 to rotate accordingly. The rotation of the second shaft 407 drives the second gear 408 to rotate accordingly. When the second gear 408 rotates, it can drive the two second tooth plates 424 to move relative to each other through the meshing state with the upper and lower second tooth plates 424. The movement of the second tooth plates 424 can drive the side frame 412 to move accordingly. When moving, the side frame 412 will be displaced along the second slide rail 409 through the connection of the second slider 411, that is, the cooperation of the second slide rail 409 and the second slider 411 plays a role of supporting and limiting the displacement of the side frame 412. At this time, the side frames 412 on both sides have completed the position adjustment according to the thickness of the books.The hydraulic rod 402 is started to clamp the books. After the hydraulic rod 402 is started and extended, the side frame 412 can be driven to move toward the bookshelf 102. At this time, through the setting of the two inclined blocks 414, the inclined blocks 414 can be inserted from the gaps on both sides of the books. As the side frame 412 continues to move, the inclined blocks 414 push the books on both sides open. The two inclined blocks 414 move to the positions on both sides of the books. As the hydraulic rod 402 continues to operate and pushes the side frame 412 to move, the two side frames 412 are completely inserted from the gaps of the books. During the initial insertion, the protruding balls 415 on the outside of the side frame 412 can provide support, so that the side frames 412 can be inserted into the bookshelf 102. The books are in contact with the ball bearing 415, and the rolling of the ball bearing 415 can reduce friction, avoid damage to the books during the process of taking and placing the books, and play a good role in protecting the collection of books. After the side frame 412 is completely inserted into the book gap, the books waiting to be taken and placed are located between the two side frames 412, and the clamping plate 419 is located on the inner side of the side frame 412. The position of the clamping plate 419 is adsorbed by the setting of the magnetic suction plate 421, so that the clamping plate 419 remains stable when not in use. After the side frame 412 is moved into place, the electric push rod 422 is started to extend, and the electric push rod 422 can drive The push block 423 moves toward the clamping plate 419. At this time, the inclined surface of the push block 423 contacts the clamping plate 419. The push block 423 can push the clamping plate 419 toward the book. After the electric push rod 422 is fully extended and maintained, the clamping plates 419 on both sides complete the clamping of the book. At this time, the hydraulic rod 402 is started to contract, which can drive the side frame 412 to move out of the bookshelf 102. The side frame 412 maintains the clamping state of the book, and the clamping operation of the book is completed. For the clamping operation of the book, the book can be inserted into the gap on both sides of the book when the books are neatly placed, which effectively improves the functionality of the equipment. After the book is clamped, the working position of the side frame 412 is adjusted by the operation of the first motor 208, the multi-stage electric telescopic rod 206 and the second motor 302. After the working position of the side frame 412 is adjusted to the placement position of the book, the hydraulic rod 402 is operated to send the book into the bookshelf 102, and the electric push rod 422 is retracted to drive the push block 423 to reset. At this time, the rebound force of the spring 417 can be used to drive the clamping plate 419 to reset, and the magnetic plate 421 is used to fix the clamping plate 419, so that the book is out of the clamping state, and the hydraulic rod 402 is retracted and reset, so that the book can be left in the bookshelf 102, and the operation of taking and placing the book is completed.
