Title:
MAGNETIC FLUX PATH CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/116835
Kind Code:
A1
Abstract:
The present invention provides a magnetic flux path control device comprising: a magnetic force moving unit including a permanent magnet for generating a permanent magnetic force, a first pole piece attached to a first surface of the permanent magnet, and a second pole piece attached to a second surface of the permanent magnet; a first outer pole piece making contact with the magnetic force moving unit so as to form a magnetic path; a second outer pole piece making contact with the magnetic force moving unit so as to form a magnetic path different from that formed by the first outer pole piece; and a magnetic path control member for releasing or generating a magnetic path by allowing the magnetic force moving unit to make contact with the first outer pole piece and to be spaced apart from or make contact with the second outer pole piece, wherein the magnetic force moving unit moves between a first position in which the first pole piece and/or the second pole piece makes contact with the first outer pole piece and the second pole piece is spaced apart from the second outer pole piece so as to desorb a target object, and a second position in which the first pole piece and/or the second pole piece makes contact with the first outer pole piece and the second pole piece makes contact with the second outer pole piece so as to adsorb the object.
