[0024] like Figures 1 to 6As shown, the present invention discloses a self-service book return device for libraries, comprising a return box 1; a handle 11 fixedly connected to the side wall of the return box 1; two sets of placement slots 12 on each side wall of the return box 1; a return frame 13 slidably connected within the placement slots 12; a scanner 14 fixedly connected to the top of the return box 1; a control plate 15 fixedly connected to the side wall of the return box 1; a set of casters 16 at the bottom of the return box 1; and the return box 1 being pushed out by a pushing component. In the prior art, in libraries, when readers return books, they generally place the books in the return area, and then staff need to re-sort the books in the return area before placing them on the shelves. However, classifying books requires considerable effort from staff, is inconvenient, and increases their workload. Therefore, this invention addresses this issue by having each return box 13 collect one type of book. When a reader places a book in the return area, the reader scans it using a scanner 14. After scanning, the scanner 14 pushes out the corresponding return box 13, which the reader then places in. The return box 13 is then retracted by the push-out component, thus completing the self-service book return process. This method ensures accurate classification and allows staff to easily place books directly onto the corresponding shelves, reducing their workload and improving their efficiency.

[0025] The pushing component includes a first slide groove 2; the return box 1 has multiple sets of first cavities 23; the bottom end of the placement slot 12 has a first slide groove 2; the bottom end of the return frame 13 is fixedly connected to a slider 22; the slider 22 is slidably connected in the first slide groove 2; a lead screw 21 is rotatably connected in the first slide groove 2, and one end of the lead screw 21 extends into the first cavity 23; the slider 22 is connected to the lead screw 21 through a lead screw nut pair; the lead screw 21 is rotated by a power component;

[0026] The power components include a first synchronous pulley 3 and a synchronous belt 31; multiple sets of annular grooves 32 are formed on both sides of the first cavity 23; multiple sets of first synchronous pulleys 3 are provided inside the first cavity 23, and sliding columns 33 are fixedly connected to the first synchronous pulleys 3, with both ends of the sliding columns 33 sliding in the annular grooves 32 on both sides of the first cavity 23; the center point of the annular groove 32 coincides with the center point of the lead screw 21; multiple sets of servo motors 34 are fixedly connected to the side wall of the return box 1; the output end of the servo motor 34 is provided with a second synchronous pulley 35; a set of first synchronous pulleys 3 and second synchronous pulleys 35 are driven by the synchronous belt 31; a set of guide rollers 36 are rotatably connected inside the first cavity 23, and the guide rollers 36 are arranged so that the wrap angle of the synchronous belt 31 and the first synchronous pulleys 3 and the second synchronous pulleys 35 matches the transmission angle; the first synchronous pulleys 3 are connected to the lead screw 21 through a connecting unit.

[0027] The connecting unit includes a first through groove 4; the lead screw 21 has a first through groove 4 at its end in the first cavity 23; a U-shaped rod 41 is slidably connected to the first through groove 4, and the side wall of the U-shaped rod 41 is fixed to the side wall of the first through groove 4 by a spring; a set of positioning through grooves 42 are provided on the first synchronous pulley 3, and the set of positioning through grooves 42 are circularly distributed; an annular magnetic block 43 is fixed to the side wall of the U-shaped rod 41; a set of annular electromagnetic blocks 44 are fixed to both side walls of the first cavity 23, and when the annular electromagnetic blocks 44 are energized, the annular electromagnetic blocks 44 and the annular magnetic blocks 43 repel each other; the center lines of the annular electromagnetic blocks 44, the annular magnetic blocks 43, the annular groove 32, and the first synchronous pulley 3 coincide.

[0028] A distance sensor 45 is fixedly connected to the side wall of the first chute 2;

[0029] During operation, after the scanner 14 scans the books to be returned, the annular electromagnetic block 44 at the corresponding return box 13 position is energized, causing the annular electromagnetic block 44 and the annular magnetic block 43 to repel each other. Simultaneously, the servo motor 34 at the corresponding position operates, causing the first synchronous wheel 3 to rotate. At the same time, the pushing action of the annular magnetic block 43 causes the U-shaped block on the annular magnetic block 43 to engage in the positioning groove of the first synchronous wheel 3. The rotation of the first synchronous wheel 3 drives the lead screw 21 at the corresponding position to rotate, thereby moving the slider 22 and allowing the return box 13 to extend out of the placement groove 12. At this time, the return boxes 13 at other positions do not... The system ensures accuracy by allowing only the corresponding category of return box 13 to extend. Simultaneously, due to the distance sensor 45, the servo motor 34 stops after the return box 13 moves to the designated position, allowing the user to place the book inside. The control tablet 15 controls the working interval of the servo motor 34; for example, after the return box 13 reaches the designated position, the servo motor 34 stops for ten or twenty seconds, then restarts in the opposite direction, returning the return box 13 to its original position. The distance sensor 45 then controls the servo motor 34 to stop again, thus completing the self-service return operation.

[0030] The bottom of the return frame 13 is provided with a first inclined surface 5; the side wall of the return frame 13 is provided with a second inclined surface 51; the first inclined surface 5 and the second inclined surface 51 are vertically distributed; during operation, the first inclined surface 5 and the second inclined surface 51 make it easy to put books in, and the books are placed in the return frame 13 at a slight upward tilt, so as to prevent the books from falling out of the return frame 13.

[0031] Working principle: After the scanner 14 scans the book to be returned, the annular electromagnetic block 44 at the corresponding return frame 13 position is energized, causing the annular electromagnetic block 44 and the annular magnetic block 43 to repel each other. At the same time, the servo motor 34 at the corresponding position works, causing the first synchronous wheel 3 to rotate. Simultaneously, the push of the annular magnetic block 43 causes the U-shaped block on the annular magnetic block 43 to engage in the positioning groove of the first synchronous wheel 3. The rotation of the first synchronous wheel 3 drives the lead screw 21 at the corresponding position to rotate, thereby moving the slider 22 and allowing the return frame 13 to extend out of the placement groove 12. At this time, the return frames 13 at other positions do not move. The system ensures accuracy by allowing only the corresponding category of return box 13 to extend. Simultaneously, due to the distance sensor 45, the servo motor 34 stops after the return box 13 moves to the designated position, allowing the user to place the book inside. The control tablet 15 controls the working interval of the servo motor 34; for example, after the return box 13 reaches the designated position, the servo motor 34 stops for ten or twenty seconds, then restarts in the opposite direction, returning the return box 13 to its original position. The distance sensor 45 then controls the servo motor 34 to stop again, thus completing the self-service return operation.
