Abstract
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.
Claims6
A disc pick-and-place device, comprising:
- a disc pick-and-place body for clamping and unloading at least one disc;
- and
- a quantity sensing unit disposed on the disc pick-and-place body for sensing a quantity of the at least one disc clamped on the disc pick-and-place body, wherein the quantity sensing unit comprises:
- a movable piece leaning on at least one disc and moving as the quantity of the at least one disc changes;
- and
- an optical distance measuring device for emitting a beam and receiving the beam reflected from the movable piece to detect the quantity of the at least one disc.
An operating method of a disc pick-and-place device, wherein the disc pick-and-place device comprises a disc pick-and-place body and a movable piece, the disc pick-and-place body is for clamping and unloading at least one disc, the movable piece leans on at least one disc and moves as the quantity of the at least one disc changes, the operating method comprising:
- emitting a beam and receiving the beam reflected from the movable piece to detect a quantity of the at least one disc;
- and
- determining whether the quantity of the at least one disc clamped on the disc pick-and-place body matches a correct disc quantity.
