Abstract
A grasping device includes a first member, a fixed member fixed to the first member, a first finger member fixed to one end of the first member, a slide mechanism fixed to the first member, a first slider member slidably attached to the slide mechanism, a second member fixed to the first slider member at one end thereof, a guide mechanism fixed to the second member, a second slider member slidably attached to the guide mechanism, a second finger member fixed to the second slider member, and a displacement increasing mechanism that transmits a relative displacement between the fixed member and the first slider member to the second slider member.
Claims9
A grasping device comprising:
- a first member;
- a fixed member fixed to the first member;
- a first finger member fixed to one end of the first member;
- a slide mechanism including a guide that is fixed to the first member, and a first slider member slidably attached to the guide;
- a second member fixed to the first slider member at one end thereof;
- a guide mechanism fixed to the second member;
- a second slider member slidably attached to the guide mechanism;
- a second finger member fixed to the second slider member;
- and
- a displacement increasing mechanism that transmits a relative displacement between the fixed member and the first slider member to the second slider member.
A robot system comprising:
- a base installed on an installation surface;
- an arm connected to the base, the arm including a plurality of arm members each of which being rotatable and/or turnable;
- and
- a grasping device attached to the arm, the grasping device including
- a first member,
- a fixed member fixed to the first member,
- a first finger member fixed to one end of the first member,
- a slide mechanism including a guide that is fixed to the first member, and a first slider member slidably attached to the guide,
- a second member fixed to the first slider member at one end thereof,
- a guide mechanism fixed to the second member,
- a second slider member slidably attached to the guide mechanism,
- a second finger member fixed to the second slider member, and
- a displacement increasing mechanism that transmits a relative displacement between the fixed member and the first slider member to the second slider member.
A method of manufacturing a mechanical product comprising:
- preparing a robot including a grasping device, the grasping device including
- a first member,
- a fixed member fixed to the first member,
- a first finger member fixed to one end of the first member,
- a slide mechanism including a guide that is fixed to the first member, and a first slider member slidably attached to the guide,
- a second member fixed to the first slider member at one end thereof,
- a guide mechanism fixed to the second member,
- a second slider member slidably attached to the guide mechanism,
- a second finger member fixed to the second slider member, and
- a displacement increasing mechanism that transmits a relative displacement between the fixed member and the first slider member to the second slider member;
- preparing a storage unit inside the fence, the storage unit storing a plurality of types of objects;
- preparing a workspace inside the fence, the workspace being a space where the robot assembles the plurality of types of objects;
- and
- transferring the objects from the storage unit to the workspace by grasping each of the objects by using the robot.
