Problems solved by technology

[0006] However, mechanical grippers and vacuum grippers have limitations in gripping objects of various sizes and shapes with adequate pressure in a non-damaging manner, making them ineffective at picking up irregularly shaped objects
In addition, in the case of electrical bonding jigs, in order to ensure a large electrical bonding force, a large contact area with the target object and application of a large voltage are required, so there is a limitation in application to picking up irregular-shaped objects

Embodiment Construction

[0038] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art to which the present invention pertains can easily implement.

[0039] In order to clearly explain the present invention, descriptions of parts irrelevant to the present invention are omitted, and the same structural elements are denoted by the same reference numerals throughout the specification.

[0040] In this specification, when a structural element is located "above" other structural elements, it includes not only the case where one structural element is located "immediately above" the other structural elements, but also the case where there are other structural elements in between. The connection of two structural elements means not only these direct contacts, but also the connection through other structural elements.

[0041] In addition, the dimensions, thicknesses, positions, and the like of each ...

Abstract

A shape compliant gripper with which an atypical object having various shapes, sizes and materials can be picked. The shape compliant gripper comprises a body and a shape compliant module disposed onthe body and having rigidity capable of being variably controlled. Further, the shape compliant module comprises a magnetorheological elastomer, a magnet part, and a control part for controlling a position of the magnet part with respect to the magnetorheological elastomer.

Description

technical field [0001] The present invention relates to a shape-adaptive fixture, in particular, to a shape-adaptive fixture for picking up irregular-shaped objects with various shapes, sizes, and materials by variably controlling rigidity. Background technique [0002] Robots are widely used to perform various operations such as welding, assembly, painting, etc. at industrial production sites. In addition, robots are widely used in all industries and service fields including professional service fields for providing various services around human life, professional services such as personal services, and medical care. [0003] In particular, with the rapid growth of the logistics market in recent years, it has become very important to increase processing speed through logistics automation. For this reason, picking robots for gripping goods, transfer robots for transferring goods, etc. are being actively developed. [0004] Among them, in the picking robot, in order to reali...
