MICRO-MANIPULATOR GRIP Russian patent published in 2005 - IPC

FIELD: micro-robotics, namely gripping devices of micro-manipulators.

SUBSTANCE: grip of micro-manipulator includes base of grip, hand of grip, elastically deformed clamping pins, drive unit and tie rod. Drive unit is in the form of linear electromagnetic motor including armature of ferromagnetic material and electromagnet with single system of windings providing possibility for one-way forward working stroke of drive unit. Tie rod is in the form of telescopic link with tubular end. Armature of linear motor rigidly joins base of grip with hand to which clamping pins are rigidly secured. Clamping pins are mutually coupled through return spring. System of electromagnet winding is arranged in telescopic link coaxial relative to armature and hand. Telescopic link may perform reciprocation motion. Inner diameter of tubular link is selected in such a way that between telescopic link and clamping pins mutually opposite effort constantly is applied.

EFFECT: increased value of clamping effort, lowered error of clamping pins motion, improved quick action of operations for gripping and releasing micro-objects.
