The invention discloses a disc library storage system including a disc library, a disc drive tower and a disc transport device. The disc library is for placing multiple discs. The disc drive tower includes multiple disc drives for reading/writing data. The disc transport device is used for moving the discs to the disc drive tower from the disc library and moving the discs to the disc library from the disc drive tower.

Disc library storage system

A disc pick-and-place device including a disc pick-and-place body and a quantity sensing unit is provided. The disc pick-and-place body is for clamping and unloading at least one disc. The quantity sensing unit is disposed on the disc pick-and-place body for sensing the quantity of the at least one disc clamped on the disc pick-and-place body. The quantity sensing unit includes a movable piece and an optical distance measuring device. The movable piece leans on at least one disc and moves as the quantity of the at least one disc changes. The optical distance measuring device is for emitting a beam and receiving the beam reflected from the movable piece to detect the quantity of the at least one disc.

Disk pick-and-place device and operating method thereof

An operating method of a disc pick-and-place device is provided. Discs can be picked up when each flexible rod is driven to rotate and make the disc pick-and-place device enter a first operating state and then a second operating state in which the first carrying portion is located at the disc releasing position and then at the disc holding position, and the second carrying portion is located at the disc releasing position in the first and second operating states. Discs can be unloaded when each flexible rod is driven to rotate and make the disc pick-and-place device enter a third operating state and then a fourth operating state in which the first carrying portion is located at the disc holding position and then at the disc releasing position, and the second carrying portion is located at the disc holding position in the third and fourth operating states.

Operating method of disk pick-and-place device

A disc grabbing device including a support body, a drive shaft, multiple first planetary gears, a center gear, multiple second planetary gears and a driver is provided. The support body includes a plate and a center column. When the disc grabbing device grabs the discs, the center column is located in the center holes of the discs. The drive shaft is rotatably disposed on the plate. The first planetary gears are respectively engaged with the drive shaft and connected to multiple first levers for driving the first levers to rotate. The second planetary gears are respectively engaged with the center gear and connected to multiple second levers for driving the second levers to rotate. The driver concurrently drives the drive shaft and the center gear to rotate the first planetary gears and the second planetary gears synchronically and make the first levers and the second levers rotate synchronically.

Disc grabbing device for grabbing a plurality of discs and sequentially unloading the plurality of discs

A disc grabbing device including a disc grabbing body, a weight sensing unit and a counter is provided. The disc grabbing body is used for grabbing or unloading at least one disc. The weight sensing unit is disposed on the disc grabbing body for sensing a weight of the at least one disc grabbed on the disc grabbing body. The counter is connected to the weight sensing unit used for obtaining a disc quantity of the discs grabbed on the disc grabbing body according to the weight.

Disc grabbing device and operating method thereof

A disc pick-and-place device for picking and clamping multiple discs and unloading the multiple discs is provided. The disc pick-and-place device includes a supporting body, multiple picking members and a driver. The picking members are disposed around a support body and flexibly abut the edges of the discs. Each picking member includes a flexible rod, a first carrying portion and a second carrying portion. The first carrying portion and the second carrying portion are located on the flexible rod and separated by an interval. The first carrying portion and the second carrying portion partly overlap with each other in an axial direction of the flexible rod. The driver is for driving each flexible rod to rotate and move each first carrying portion and each second carrying portion to a disc releasing position or a disc holding position.

Disk pick-and-place device and operation method thereof

An opening and closing device of rotating cage type jukebox disc tray including a first disc tray carrying discs and an opening and closing mechanism of disc tray including a first linkage mechanism and a first driving device is provided. The first linkage mechanism includes a first linkage bar, a first sliding member and a second linkage bar. The second linkage bar is slidingly disposed on the first sliding member which is slidingly disposed on the first linkage bar. When an end portion of the second linkage bar is connected to a first ear portion on a lateral side of the first disc tray, the first driving device drives the first sliding member to slide on the first linkage bar, leading the second linkage bar to slide on the first sliding member and thereby leading the first disc tray to rotate around a first fixing post.

Opening and closing device of rotating cage type jukebox disc tray

A disc grabbing device including a body, a drive shaft, a first cam, a second cam, multiple first movable parts and multiple second movable parts are provided. The drive shaft is rotatably disposed in the body. A first cam and a second cam are disposed on the drive shaft, and rotate together with the drive shaft. The first movable parts are disposed in the body and correspond to the first cam, and move to a disc hold position or a disc release position along with the rotation of the first cam. The second movable parts are disposed in the body and correspond to the second cam, and move to a disc release position or a disc hold position along with the rotation of the second cam.

A system and method for adjusting optical drives. Rotating disc datum, and leader pin datum, must be adjusted to a specific position during a packaging process. An autocollimator according to the present invention senses tilt and sway of the rotating disc, outputting a first bright spot through a switch box to a monitor. In addition, an optimum tilt angle of the optical pickup head is obtained by a reader through calculation by a host, outputting a second bright spot through the switch box to the monitor. Therefore, the first bright is coincided with the second bright spot by a adjustment mechanism and according to picture switch by the switch box, reading optimum tilt angle adjustment. Furthermore, individual tilt angle of each optical pickup head is calculated by a host for satisfying adjustment of different tilt angles with different optical paths in reading CD and DVD discs.
