Tweezers and prehension sytem

摘要

The tweezers (12) has branches (16, 18) joined at an axial end (20) of the tweezers and forming a gripping claw (22) at another axial end for capturing a small component (14) e.g. display hand, using the claw by manual operation of the tweezers, where the branches are made of electrical conductor material e.g. foam. The branch (16) has an electrostatic gripping surface (24) that captures the component by an electrostatic attraction and is arranged on a side of an external surface of the branch (16). A guiding portion forces the component to occupy a determined position on the surface.
