Description

Automatic CD

The utility model relates to a kind of CD storage library, particularly can pick up the CD server of CD automatically.

Development along with modern technologies, CD is as a kind of mobile storage medium, its capacity is big, easy to carry, inexpensive, be used widely, because CD is on the increase, still adopt existing CD tower, DVD multidisc CD-ROM drive storage CD, its storage capability is little, be far from suitable, and, pick up wherein a slice in the face of a large amount of CDs that overstock, more seem unable to do what one wishes.Because CD is a thin rounded flakes, more difficult clamping, direct manual chucking optical disk also damages CD easily, causes the permanent destruction of optical disc information.

The purpose of this utility model is that a kind of storage CD quantity of design is many, can not damage CD, and is simple in structure, cost is low, have and pick up CD function, automatic CD easy to use automatically.

Technical solution of the present utility model is, automatic CD comprises the circular housing that contains CD drive, the sheet folder of giving out light and coiling, the inner ring opening of circular housing, the inwall of outer ring has the steaming stern notch, the inwall of two ring surfaces is furnished with the slot that the feed folder is planted, the sheet folder is a hollow frame, framework is provided with CD positioning supports piece and is used to clamp the elasticity folder of CD, wherein one side that sheet presss from both sides relative both sides has the dovetail breach, another side is provided with the hasp that matches with the housing dovetail groove, utilize hasp and housing to fix, the loose clamp device that unclamps elasticity folder on the sheet folder is being housed on the CD drive, radially be fixed with support respectively at housing two ring surfaces, one is positioned at the housing center of circle, with the support be vertically be fastened with in the rotating shaft of supporting two apart, the plate that parallels constitutes revoliving arm, it is turned round in the hole of circular housing by motor-driven, on two blocks of parallel-plates of revoliving arm, have chute, two opposite side of board-like loading arm insert in the chute and are slidingly connected with revoliving arm formation, its end is a wedge-like, place the dovetail breach of sheet folder, and and the dovetail breach between leave the space, this loading arm turns round together in company with revoliving arm, tooth bar is housed on loading arm, be fixed with motor on the parallel-plate of revoliving arm, gear that installs on this motor shaft and the engagement of the tooth bar on the loading arm, the traction loading arm slides in chute, the sheet folder radially advances with the loading arm sliding translation, go out housing.

This automatic CD, every CD is fixed with a sheet clamping, and the sheet folder can seamlessly be placed in the housing, and storage CD quantity is many, does not also worry the scratch CD.During work, externally under the software control, realize making revoliving arm to forward the angle of arbitrary needs to, utilize the slip of loading arm to take out or put into the discs folder by two motors.Therefore the sheet gripping can be gone out put into CD drive or take out sheet to fold up reposition from CD drive, even the position of changing plate folder.

Below in conjunction with accompanying drawing the utility model is described in further detail.
