Disc extractor with automatic protective device and disc extracting method

Abstract

The invention discloses a disc extractor with an automatic protective device; the disc extractor comprises a disc extractor body and a protective device, wherein the disc extractor body comprises a disc extracting hook and a horizontal movement mechanism; the protective device is arranged at the internal side of the disc extracting hook and comprises a shell, an electromagnet, a spring and an ejector rod; the electromagnet, the spring and the ejector rod are arranged in the shell; the ejector rod is arranged on the electromagnet and stretches out of the shell under the driving of the electromagnet. The invention further discloses a disc extracting method. When the extracting plate of a disc tray is extracted by the disc extracting hook of the disc extractor, the ejector rod of the protective device stretches out, is clung to the extracting plate of the disc tray and commonly clamps the extracting plate of the disc tray along with the disc extracting hook, so that the slip of the disc extracting hook is solved effectively when the present disc extractor extracts the disc tray; the disc extracting stability and success rate of the disc extractor are improved and the working efficiency of the disc extractor and a manipulator is improved.

Description

technical field [0001] The invention relates to an optical disk library, in particular to an automatic protection device and method for a disk drawer. Background technique [0002] The optical disc library is a mass data storage device that uses standardized optical discs as data storage media. The optical disk library is connected with the computer through the data communication interface, and the data on all the optical disks in the optical disk library is automatically provided to the user through the management software of the optical disk library. At the same time, users can also easily write data to the discs in the disc library. Therefore, optical disc libraries are widely used in long-term archiving and preservation of data. [0003] figure 1 A compact disc library is shown. The optical disc library 1 is composed of at least one optical disc magazine 2, an optical drive 3, a manipulator assembly 4 for transferring an optical disc 6 between the optical disc magazi...

AI Technical Summary

Problems solved by technology

However, there are some problems in such an arrangement. Since the disc extractor only extracts the strips on one side of the disc tray, it is easy to cause uneven force during extraction, and the disc tray is often very thin. Therefore, in the process of extracting the disc, the disc extractor often Slipping and causing draw failure
