Problems solved by technology

[0005] However, this setting method has disadvantages: the position error of cassette extraction will accumulate, and the farther away from this reference point, the greater the error accumulation
This requires very high machining accuracy for the optical disc library, and a slight deviation may cause malfunction

Embodiment 1

[0026] A method for improving the accuracy of extracting optical discs from an optical disc library is used to improve the accuracy of extracting optical discs 3 in the optical disc extraction system of the optical disc library.

[0027] Such as figure 1 As shown, the disc library optical disc 3 extracting system of the present invention includes a manipulator 4 and an extracting device arranged on the manipulator 4 . When the disc library is working, the disc extractor 5 in the manipulator 4 draws out a certain tray 2 in the magazine 1 in the horizontal direction according to the corresponding software instructions, and the disc grabber in the manipulator 4 grabs the disc 3 through the round hole in the middle of the disc 3. The disc drawer 5 in the manipulator 4 now pushes the tray 2 back to the original position of the cassette 1, and the manipulator 4 delivers the picked-up optical disc 3 to the designated position through horizontal and vertical movements. This specified...

Embodiment 2

[0032] Such as figure 1 As shown, an optical disc extracting system of an optical disc library includes a manipulator 4 and an extracting device arranged on the manipulator 4 . When the disc library is working, the disc drawer 5 in the manipulator 4 draws out a certain disc tray 2 in the magazine 1 in the horizontal direction according to the corresponding software instructions, and the disc grabber in the manipulator 4 grabs the disc 3 through the round hole in the middle of the disc 3 At this time, the disk drawer 5 in the manipulator 4 pushes the tray 2 back to the original position of the cassette 1, and the manipulator 4 delivers the picked-up optical disc 3 to the designated position through horizontal and vertical movements. This specified location can be: the magazine tray 2 of another optical disc 3, the optical disc drive that has opened the optical disc drive tray by instruction in advance, the optical disc mailbox, the disc label printer, or the flipper and the lik...

Abstract

The invention discloses a method for improving compact disc extraction accuracy of a compact disc library, which is used for improving compact disc (3) extraction accuracy in a compact disc extraction system of the compact disc library. The extraction system comprises a manipulator (4) and an extraction device arranged on the manipulator (4); when in work, more than one datum reference points areset for the compact disc library, each datum reference point is taken as a regional datum reference point of a section of region of the compact disc library, and used for determining a compact disc (3) extraction position in the section of region; the extraction position is determined by calculating displacement amount away from the datum reference point, so that the compact disc (3) positioned in any arbitrary cassette (1) in the compact disc library can be extracted according to needs. Simultaneously, the invention also discloses a compact disc extraction system of the compact disc library using the method. The method and the compact disc extraction system of the invention can greatly reduce the error accumulation of vertical movement of the manipulator, enhance the reliability of the compact disc library effectively, and reduce the calibration difficulty and workload.

Description

technical field [0001] The invention relates to the technical field of optical disc library, in particular to a method and system for improving the accuracy of extracting optical discs from the optical disc library. Background technique [0002] The optical disc library is an opto-mechanical and electrical integration device used to store a large amount of data. A modern optical disc library usually consists of one or more cassettes, one or more optical disc drives and the corresponding manipulator. See figure 1 . Magazines contain multiple disc trays for storing discs, see figure 2 . This type of cassette is especially suitable for a type of optical disc library that grabs the optical disc from the middle of the cassette tray through the round hole in the middle of the optical disc. The following patent documents can be referred to for typical optical disc library and magazine: DE 19700741 A1, DE 19700741 C2, DE 19644158 A1, DE 4314387 A1, DE 4134241 A1, EP 000001066635...
