Optical disc thickness identification device and optical disc thickness identification method for optical disc library

Abstract

The invention discloses an optical disc thickness identification device for an optical disc library, comprising: a disc gripper, a controller and a displacement sensing device, the displacement sensing device is a contact linear displacement sensing device and is arranged on the disc gripper, The disc grabber is used to grab and unload the discs in the disc box; the displacement sensing device is used to sense the depth of the disc grabber entering the disc center hole, and the controller is used to control the disc grabber to grab all the discs and then unload the discs one by one, obtain Displacement data collected by the displacement sensing device, and the number of discs stored in the disc case and the thickness of each disc are calculated according to the displacement data. The invention also discloses a disc thickness identification method based on the device. The optical disc thickness identification device of the present invention can accurately identify the thickness and corresponding depth of each optical disc stored in a disc case, reduce the operation error of the disc grabber, effectively reduce the failure rate of the disc library, and improve the gripping rate. The work efficiency and degree of automation of the tray.

Description

technical field [0001] The invention relates to a manipulator assembly of an optical disc library, in particular to an optical disc thickness identification device and an optical disc thickness identification method for the optical disc library. 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. The existing optical disc library includes a disc magazine, an optical drive, a manipulator assembly and a control unit. Lifting and moving horizont...

Problems solved by technology

[0007] However, due to the uneven thickness of a plurality of optical discs stored in a disc case, grabbing the optical disc without knowing the thickness of each optical disc will lead to wrong judgment of the grabbing position, which will lead to misoperation of the disc grabber, resulting in Damage to the disk grabber and the disc, or even loss of the disc, not only reduces the work efficiency and poor accuracy of the disc grabber, but also increases the cost
