Title:
PICK-AND-PLACE APPARATUS AND MECHANICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/226792
Kind Code:
A1
Abstract:
The present invention provides a pick-and-place apparatus and a mechanical device. The pick-and-place apparatus comprises: a joint portion; a grabbing assembly, comprising positioning shafts, movable shafts, and first elastic members, each positioning shaft comprising an expansion portion, and each movable shaft and each first elastic member being disposed in the corresponding positioning shaft; a driving assembly, configured to drive the movable shafts to move in a first direction relative to the positioning shafts, so that the first elastic members store elastic potential energy, and also to cause the movable shafts to apply an acting force along the positioning shafts to the expansion portions, so as to increase the outer diameters of the expansion portions; and a locking assembly, disposed on the driving assembly. When the locking assembly is connected to the grabbing assembly, the movable shafts are prevented from moving in a second direction relative to the positioning shafts; when the locking assembly is disconnected from the grabbing assembly, the first elastic members are allowed to release the elastic potential energy under a predetermined condition and the movable shafts are caused to move in the second direction relative to the positioning shafts to cancel the acting force applied to the expansion portions; the first direction is opposite to the second direction, and is parallel to the axial direction of the positioning shafts. The pick-and-place apparatus can stably grab a target object.
