Vertical position automatic calibrating method for CD library

Abstract

The invention discloses a method for automatically calibrating the vertical position of a CD (Compact Disk) library extractor. Datum marks are respectively arranged in the middles of the vertical direction of the first trays of each cassette in a CD library. The extractor successively and gradually approaches to and extracts the first trays at both ends of the vertical direction of an object cassette respectively from the outer sides of both ends until the positions of the first trays at both ends are respectively and firstly extracted, the difference of the two positions is calculated and divided by the number of trays in the object cassette, and the result is rounded to finish calibration. The invention does not need manual interference and debugging, can automatically run to realize the calibration of the vertical position of the CD library extractor, saves labor and debugging time, and greatly facilitates the mounting, the debugging and the use of the cassettes in different CD libraries so as to facilitate the exchange and the remote storage of data.

Description

technical field [0001] The invention relates to an automatic calibration method for the vertical position of a disk drawer of an 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. Typical optical disc library and cassette can refer to the following patent documents: DE 19700741 A1; DE 19700741 C2; DE 19644158 A1; DE 4314387A1; DE 4134241 A1; EP 000001066635 B1; [0003] When the disc library is working, the disc drawer in the mani...

Problems solved by technology

[0006] This traditional method of manual calibration has the following disadvantages: ① Time-consuming and labor-intensive; ② The quality of the optical disc library product is related to the experience and technical level of the debugging personnel; ③ External influences such as the vibration of the optical disc library will affect its stable work. , at this time, technicians need to go to the site to re-debugging

[0008] However, because the traditional manual calibration method can only be carried out for the cassette currently in the optical disc library body each time, and the cassette is usually made of plastic injection molding, there is a certain mechanical error between them, so it is better to calibrate for a certain cassette In the optical disc library, when the magazine is replaced, there may be deviations in the alignment of the mechanical arm drawer, and even manual intervention is required

This also greatly limits the interchangeability of the optical disc library cassette, affecting data exchange and off-site storage
