Soft grip head, soft grip unit having the same, and grip device having the soft grip unit

Abstract

In a soft grip head, a soft grip unit having the soft grip head, and a grip device having the soft grip unit, the soft grip head has a suction pad and the suction pad makes contact with an object. The suction pad includes a sidewall and a plurality of suction cells. The sidewall divides the suction pad into a plurality of spaces, and both ends of each of the spaces are open. A plurality of suction cells is respectively formed by the spaces divided by the sidewall. The suction pad includes a material having a stiffness along an axial direction smaller than a stiffness along a width direction. The suction cells extend along the axial direction, and the width direction is substantially perpendicular to the axial direction.
