A device for automatically grabbing and separating optical discs for optical disc library

Abstract

The invention discloses a device for automatically grabbing and separating optical discs used in a disc library, which includes a gripper seat, a gripper central axis, a pressure bar assembly, a disc splitting needle assembly, a servo motor, a miniature photoelectric sensor assembly, and a gripper module assembly. Plate, sub-disc motor gear, and large gear assembly. The large gear is installed on the handle seat through the central axis of the gripper. The sub-disc motor gear meshes with the large gear. On the basis of the feedback information of the photoelectric sensor, through the reciprocating rotation of the dividing needle and the cooperation of the disc pressure rod under the handle seat, the grasping and separation of the disc is realized. The invention solves the problem of long stroke and time-consuming for the electromechanical device of the optical disc library to grab, move and separate the optical discs, and can move multiple optical discs between the optical disc box and the optical drive at one time, which is a small volume, fast speed and stable The high-level electromechanical device for intelligently separating and picking up discs improves the disc access efficiency and stability of disc storage devices.

Description

technical field [0001] The invention relates to the field of large-capacity optical storage equipment, in particular to a device for automatically grabbing and separating optical discs for an optical disc library. Background technique [0002] Optical storage technology is a mass data storage method that uses optical discs as storage media. It has the advantages of high data storage stability, long storage time, low energy consumption, and low maintenance costs. The optical storage technology is fully used in the optical storage library. The optical disc is the main storage medium, and it is a device that realizes a large amount of data storage. The optical disc grasping and separating device outside the optical disc library is a complex mechatronic system, especially for grasping optical discs and separating discs one by one, various sensors and components need to cooperate with each other, including servo motors, gripper seats, gripper central shafts, Disc pressure lever,...

AI Technical Summary

Problems solved by technology

[0004] The present invention overcomes the poor operational stability of the optical disc grasping and separating mechanical device of the optical disc library system when grasping a single optical disc, the inability to accurately realize the stable separation of optical discs one by one when the mechanical device separates multiple optical discs, and the low working efficiency of optical disc grasping and separating optical discs , the shortcoming that the whole process is not simple and fast enough, the technical problem to be solved by the present invention is to provide a servo motor to drive the large gear to rotate and cooperate with the four disc pin gears to grasp and separate the disc device, the large gear rotates at a corresponding angle In this way, the sub-disc gear is driven to rotate at a corresponding angle, and the raised groove at the bottom of the sub-disc needle is used to achieve the purpose of rotating the sub-disc needle and grabbing and separating the disc. The way of matching the grooves of the thickness of the disc makes the discs be separated accurately one by one and other technical solutions, which realizes the quick and easy operation of the whole operation, and improves the disc access efficiency and stability of the disc storage device
