Method for loading and unloading disks through expanding and carrying combined type disk gripper

Abstract

The invention discloses a method for loading and unloading disks through an expanding and carrying combined type disk gripper. The method comprises S1, in a disk jukebox, a mechanical arm moves to a designated disk cell to open the disk tray of the designated disk cell; S2, the disk gripper expands N disks inside the disk tray through upper-layer tooth pieces and carries the N disks through lower-layer tooth pieces; S3, the disk gripper moves above a target tray, expands the N-1th disk through the upper-layer tooth pieces and enables the Nth disk to fall off inside the target tray through the lower-layer tooth pieces. By taking and placing the disks through an expanding and carrying combined mode, the method for loading and unloading the disks through the expanding and carrying combined type disk gripper expands the application range, achieves the function of gripping the disks in one step and continuously placing down multiple disks and accordingly improves the operating efficiency.

Description

technical field [0001] The invention relates to the carrying of optical discs in an optical disc library, in particular to a method for loading and unloading optical discs in the optical disc library by means of a combination of expansion and support. Background technique [0002] The optical disc library is a mass data storage device that uses standardized optical discs as the data storage medium. The traditional optical disc storage method is to place a disc in a disc case. Due to the small storage capacity and large space occupation of this method, As a result, it is gradually replaced by another storage method, that is, multiple CDs are stacked in a CD box. This new storage method expands the storage capacity of the CD library and saves the space of the CD library, but it also brings some discs. How to grab a specified CD from a plurality of stacked CDs is a difficult problem that must be overcome in this storage method. For this reason, the patent application No. 20121...

Problems solved by technology

However, this method realizes the separation of the disc by the protruding end of the insert on the disk grabber. Specifically, the protruding end of the upper insert is inserted into the gap between the stacked discs to complete the separation of the disc. During the process, the protruding end also needs to support one or more discs, which puts forward higher requirements on the processing technology of the protruding end; in addition, because the gap between the discs after ordinary discs is stacked is very small, the insertion end is used The mode of inserting disc gap can only be used for the disc of special structure (that is, the disc whose central hole edge thickness is far smaller than the thickness of the main body), and is not suitable for ordinary discs, which limits the scope of application of this disc-grabbing method; at the same time, using this The method of grabbing the disc needs to align the protruding end of the upper insert with the gap between the discs, which puts forward very high requirements for positioning accuracy, and is prone to errors in actual operation
