Technical Field
[0001] This utility model relates to the field of book-clamping robotic arms, and in particular to a robotic arm book-clamping device. Background Technology
[0002] After book signatures are stacked in the printing industry, robotic book-gripping devices are typically used for picking and placing. These devices, using robotic arms equipped with specialized grippers, enable precise gripping and placement of book signatures. Their core functions include clamping, lifting, moving, and releasing book signatures, ensuring stability and accuracy even at high speeds. These robotic book-gripping devices usually incorporate sensors and control systems to identify the position and thickness of book signatures and automatically adjust the clamping force to accommodate book signatures of different sizes and materials. This improves production efficiency, reduces manual labor intensity, and is an important component of modern printing automation.
[0003] Traditional robotic book-gripping devices primarily rely on mechanical structures to grasp and move book samples. During operation, the robotic arm typically uses a motor or cylinder to drive the gripping mechanism, aligns the book sample with its position, clamps it in place, and then lifts and moves it to the target location before releasing it. This device usually operates along a preset trajectory or with manually adjusted paths, and is suitable for handling book samples of fixed sizes and specifications. However, traditional devices have a low level of automation, are highly sensitive to the thickness and position of the book samples, require manual calibration during operation, and are relatively less efficient than modern intelligent robotic arms.
[0004] Traditional robotic book-clamping devices suffer from design limitations. They typically employ rigid structures with a single motion trajectory, and the size and gripping method of the clamps are fixed, making it difficult to flexibly adapt to complex or confined spaces, thus hindering the picking up and placing of book pages.

[0029] Working principle: When the robotic arm book-clamping device is needed, firstly, the rotary cylinder 3 is activated to move the rotating shaft 4, which in turn moves one end of the connecting rod 6. Then, the other end of the connecting rod 6 drives the sliding seat 19 to slide inside the side plate 2. Subsequently, the sliding seat 19 drives the connecting column 20 to move. At this time, the two ends of the connecting column 20 drive one end of the support seat 10 to move, causing one end of the support seat 10 to slide inside the side plate 2. At the same time, the bracket 21 supports the middle part of the support seat 10. When the support seat 10 moves to... In the parallel state, the booklet 12 can be placed above the support base 10. Then, the telescopic cylinder 8 is activated to drive the push plate 9 to move, thereby pressing down the slide plate 5 through the push plate 9. In turn, the slide plate 5 drives the pressure plate 11 to slide on the outer wall of the guide post 7. Then, the pressure plate 11 presses down on the top of the booklet 12 to fix the booklet 12. When it is necessary to pick up or put down the booklet 12, the rotary cylinder 3 is driven to move the connecting rod 6, thereby moving the support base 10 down, causing the booklet 12 to loosen, and then the booklet 12 can be picked up or put down.
[0030] In addition, the drive motor 13 drives the lead screw 14 to rotate. In conjunction with the threaded relationship between the lead screw 14 and the threaded plate 16, the threaded plate 16 drives the side plate 2 to move with the rotation of the lead screw 14. Then, in conjunction with the guidance of the guide post 17, the side plate 2 on one side moves, thereby adjusting the distance between the two side plates 2, so that different sizes of bookplates 12 can be used.
