Claims6
A hand device for working robot comprising:
- a grip capable of gripping or releasing a workpiece;
- a movable body provided on a driving base so as to extend or retract by a driving means;
- a link means for linking an extending or retracting movement of the movable body with a gripping or releasing movement of the grip;
- and
- a workpiece drop prevention means for preventing a workpiece from dropping by attaching to the movable body to stop the releasing movement of the grip when the driving means is stopped,
- wherein the workpiece drop prevention means further comprises a protrusion stick with a tapered tip, a support rail supporting the protrusion stick so as to slide the protrusion stick between a protrusion position wherein the protrusion stick abuts the movable body and a retracted position wherein the protrusion stick is free from contacting the moveable body, a momentum means for pushing the protrusion stick supported by the support rail at the protrusion position, and a holding means for holding the protrusion stick at the retracted position resisting against the pushing of the momentum means in a normal state and for releasing the protrusion stick when the driving means is stopped operating.
