摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
