Automatic quick accurate positioning device and method for optical disk cartridge of optical disc juke-box

Abstract

The invention discloses an automatic quick accurate positioning device for an optical disk cartridge of an optical disc juke-box. The device comprises a manipulator, an actuating unit, horizontal slide rails and vertical slide rails and further comprises two home positioning correlation sensors and a horizontal blocking piece and a vertical blocking piece, wherein the horizontal blocking piece and the blocking piece are matched with the two home positioning correlation sensors and used for limiting a home position. The manipulator is provided with a reflective sensor, and the reflective sensor can move vertically or move horizontally in the direction parallel to the side of an opening of the optical disk juke-box with the manipulator for vertically and horizontally scanning the optical disk cartridge for further achieving accurate positioning in a coordinate system with the home position serving as the origin of the coordinate and a detection opening as a center point. The automatic quick accurate positioning device for the optical disk cartridge of the optical disc juke-box uses the relative position for the positioning, omits manual intervention for debugging and repeatedly drawing for adjusting the position of the optical disk cartridge, and has the advantages of saving the positioning time and improving the accuracy of the positioning.

Description

technical field [0001] The invention relates to a positioning device and method, in particular to an automatic fast and precise positioning device and method for a disc box of a disc library. Background technique [0002] An optical disc library is an optical disc network sharing device with a robotic arm. The optical disc library is generally composed of three parts: a disc rack for placing discs, a robot arm and a drive. In recent years, CD-ROM has become an indispensable information carrier in today's information society due to its incomparable advantages of traditional recording media such as large capacity, low cost, standardized data format, easy storage, safety and reliability, convenient use and easy portability. medium. Compared with common storage devices such as disk arrays and tape libraries, the price and performance advantages of optical disk libraries are increasingly revealed. With the gradual increase in the number of optical discs in various organization...
