[0029] Specifically, the user fixes the publication on the top surface of the placement plate 9, controls the second servo motor 23 to drive the first curved plate 21 and the second curved plate 22 to rotate slowly and uniformly, and when the first curved plate 21 and the second curved plate 22 rotate, the second curved surface contacts the pressing plate 19, and the pressing plate 19 is at the lowest position at this time. The second curved surface rotates along the top surface of the pressing plate 19, and the height of the pressing plate 19 remains unchanged until the second curved surface starts to move away from the pressing plate 19, and the second spring 20 starts to push the pressing plate 19 to move upward until the pressing plate 19 contacts the pressing plate 19. The first arc surface is touched, and the pressing plate 19 moves to the highest position. During the upward movement of the pressing plate 19, the rack 24 is driven to move upward. The movement of the rack 24 drives the transmission gear 18 to rotate. The rotation of the transmission gear 18 drives the rotating rod 25 and the second bevel gear 16 to rotate.

When the first curved surface rotates on the top surface of the pressing plate 19, the height of the pressing plate 19 remains unchanged, and the rotating plate 8 is in a stationary state. The user can control the electric telescopic rod 6 and the vacuum pad 7 to perform the labeling operation, and then fix another group of publications to be labeled on the top surface of the placement plate 9 close to the user. When the second curved surface begins to contact the pressing plate 19, the rotation of the second curved surface drives the pressing plate 19 to move downward until the pressing plate 19 moves to the lowest position. At this time, the rotating plate 8 just rotates 180 degrees, thereby rotating the labeled publications to their original positions, and at the same time, another group of publications to be labeled rotates to the bottom of the vacuum pad 7. When the second curved surface continues to rotate, the height of the pressing plate 19 remains unchanged, and the rotating plate 8 is in a stationary state.

[0032] The second servo motor 23 is controlled to drive the first curved plate 21 and the second curved plate 22 to rotate slowly and uniformly. When the first curved plate 21 and the second curved plate 22 rotate, the second curved surface contacts the pressure plate 19. At this time, the pressure plate 19 is at the lowest position. The second curved surface rotates along the top surface of the pressure plate 19. The height of the pressure plate 19 remains unchanged until the second curved surface starts to move away from the pressure plate 19. The second spring 20 starts to push the pressure plate 19 to move upward until the pressure plate 19 contacts the first curved surface and the pressure plate 19 moves to the highest position. The pressure plate 19 moves upward. During the movement, the rack 24 is driven to move upward, the movement of the rack 24 drives the transmission gear 18 to rotate, the rotation of the transmission gear 18 drives the rotating plate 8 to rotate, and when the pressing plate 19 moves to the highest position, the rotating plate 8 just rotates 180 degrees, so that the position of the publication to be labeled is rotated to just below the vacuum pad 7, and when the first arc surface rotates on the top surface of the pressing plate 19, the height of the pressing plate 19 remains unchanged, the rotating plate 8 is in a stationary state, and the external conveyor belt transports the label to the bottom of the vacuum pad 7, and the vacuum pad 7 can adsorb the label, and the electric telescopic rod 6 is controlled to carry The movable vacuum pad 7 moves downward to label the publications, and then another group of publications to be labeled are fixed on the top surface of the placement plate 9 close to the user. When the second curved surface begins to contact the pressing plate 19, the second curved surface rotates to drive the pressing plate 19 to move downward until the pressing plate 19 moves to the lowest position. At this time, the rotating plate 8 just rotates 180 degrees, thereby rotating the labeled publications to their original position, and at the same time, another group of publications to be labeled are rotated to the bottom of the vacuum pad 7. When the second curved surface continues to rotate, the height of the pressing plate 19 remains unchanged, and the rotating plate 8 is in a stationary state. The user can lift the handle to remove the labeled publications for replacement, and control the electric telescopic rod 6 and the vacuum pad 7 to perform the labeling operation until the pressing plate 19 starts to move upward. Repeating the above operation can realize the periodic rotation of the rotating plate 8 and the publications by 180 degrees and stationary, which is convenient for the vacuum pad 7 to periodically label the publications and improve the labeling efficiency. The vacuum pad 7 is away from the user during the labeling of the publications, thereby preventing the user from being squeezed by the vacuum pad 7 and reducing the risk factor of the device.
