Robot gripping device

A robot gripping device having two or more finger parts, in which front ends of the finger parts move toward a center of grip so as to grip an object to be gripped,

• each finger part having a finger part body which is comprised of at least two or more plate-shaped elastic members, a first anti-slip part which is provided at an inside surface of a front end side of the finger part body, and a reinforcing member which is arranged along an outer surface of the finger part body, is connected to the front end of the finger part body, and is higher in rigidity than the finger part body,
• said front ends and the base ends of the at least two or more plate-shaped elastic members of the finger part body being secured to one another while the at least two or more plate-shaped elastic members are overlapped one another in their thickness direction,
• said finger part body being one of finger part bodies which extend toward the center of grip and face each other,
• said reinforcing member having a first rotary joint which makes the reinforcing member pivot about a first axis of rotation which is perpendicular to the longitudinal direction of the finger part body and which is parallel to the surface of the finger part body, and
• said robot gripping device having a drive part which makes a base end of the finger part body move along the center of grip to make the finger parts open and close, wherein
• when said drive part makes the base ends of the finger part bodies move downward along the center of grip, the finger part bodies of the finger parts are curved outward and are spaced from each other, so that the finger parts are made open, and
• when said drive part makes the base ends of the finger part bodies move upward along the center of grip, the finger part bodies of the finger parts are curved inward, so that the finger parts are made close.
