Fabrication method of picking arm structure for library book picking robot

1. The utility model relates to the technical field of library robot equipment, in particular to a pickup arm structure for a library book pickup robot.

Background technique:

2. The library has a large number of books borrowed every day, and operations such as book identification and book retrieval require a lot of manpower. The use of robot technology to realize automatic identification and book retrieval can not only reduce the labor intensity of librarians, but also improve work efficiency. The library book retrieval robot mainly includes a bookshelf mechanism, a gripping mechanism, a walking mechanism, a path-finding mechanism and Information collection mechanism, wherein the existing bookshelf mechanism includes a casing, a clamping arm, a clamping arm tightening drive mechanism, a clamping arm translation driving mechanism and a clamping arm lifting drive unit, a pair of clamping arms are rotatably mounted on the casing, and the clamping arms are retracted. The clamping drive mechanism drives a pair of clamping arms to move toward each other to clamp the book, the translation drive mechanism of the clamping arm drives the clamping arm to translate to insert the two sides of the book to be taken, and the clamp arm lift drive unit drives the clamp arm to lift and move to the same height of the book to be taken. .

3. In this regard, the Chinese utility model patent with the authorization announcement number cn108818505a discloses a library book picking robot, the robot includes a base, a lift seat is vertically installed on the base, and a groove is arranged in the lift seat along the vertical direction, A lead screw is arranged in the groove, and the lead screw is connected with the lead screw motor installed on the lifting seat through a coupling; a rotating motor is installed at the top of the lead screw, and a support plate is connected above the rotating motor through a rotating table; the support plate clamps The robot drives the lead screw to rotate through the lead screw motor, so that the vertical height of the robot can be easily adjusted; the rotating motor drives the rotating table to rotate, which in turn drives the book picking device on the rotating table to rotate, thereby facilitating book picking; When the electric telescopic rod is compressed to the right, the driving rod drives the splint to move to the right together, so that books can be easily picked up.

4. The robot has a simple overall structure and is easy to use. It mainly relies on two splints to grip and move books. However, the current books are beautiful, and most of the book covers are covered with films, which leads to the vertical gripping of multiple books. When the friction between the books is small, the phenomenon of falling occurs.

5. For this reason, we propose a pick-up arm structure for a library book pick-up robot to solve the above problems.
