Mechanical arm applied to optical jukebox

Abstract

The invention discloses a mechanical arm applied to an optical jukebox. The mechanical arm applied to the optical jukebox comprises a pair of disc taking fingers, wherein each disc taking finger is provided with a protruding edge which extends out of the main body of the disc taking finger, a clamping and fixing structure is arranged on each disc taking finger, the clamping and fixing structures and the protruding edges are arranged on the same side, the protruding edges and the clamping and fixing structures of the pair of disc taking fingers are arranged oppositely, the outer end of each protruding edge is thinner than the inner end of the protruding edge, the protruding edges can be directly clamped on the top end face of an optical disc cartridge, then the optical disc cartridge can be kept horizontal all the time when the optical disc cartridge is clamped, tilting, rotating and even disengaging due to the fact that only one clamping point or only one clamping surface exists are avoided, the mechanical arm can effectively be matched with the bending curve of the optical disc cartridge due to the design of the clamping and fixing structure, and stability of the optical disc cartridge is guaranteed.

Description

technical field [0001] The invention relates to a manipulator structure, in particular to a new manipulator used in an unattended automatic disc library, which belongs to the field of mechanical automation. Background technique [0002] The library is the collection center of physical materials such as books, periodicals, newspapers, CDs, etc. The collection, arrangement, storage and use of these materials have long been the main functions of the library. With the widespread use of multimedia media, more and more readers tend to use multimedia media, and CDs have the functions of small size and large capacity, and are widely used in the storage of various information, such as electronic versions of paper books, music, etc. Documents, audio-visual files, game software, functional software, etc. Readers' demand for using CDs is increasing day by day, and the management and borrowing of CDs has become a new function of the library. The library manages and borrows CDs in the s...

AI Technical Summary

Problems solved by technology

Use the above-mentioned clamping air claws to clamp the disc case. When the clamping force is small, it is easy to only clamp the outer edge of the disc case, but the entire disc case cannot be clamped.

When the clamping force is large, the outer periphery of the disc case is easily damaged, and often the disc case is deformed by the external clamping force (dotted line), so the clamping air claws still cannot grasp the disc case

Therefore, the grasping of the disc case cannot be completed, and the design of the clamping air claw cannot ensure that the disc is always in a horizontal state. When the disc case is skewed, even if the disc can be grasped, the precise storage of the disc case cannot be completed
