MAGNETIC ATTRACTION UNIT AND MAGNETIC ATTRACTION ROBOT

WIPO Patent Application WO/2023/038079

A1

In a magnetic attraction unit (1A), a permanent magnet (3), a rod (4), and a cam follower (5) are supported by a frame (2), which abuts an attachment surface (S), so as to be able to advance and retreat with respect to the attachment surface (S). A cam (6) is provided with a cam surface (6b) which abuts the cam follower (5) from the attachment surface (S) side, and is supported by the frame (2) so as to be able to slide or rotate. When the cam (6) slides or rotates, the cam surface (6b) causes the cam follower (5) to advance and retreat with respect to the attachment surface (S). An elastic member (7) applies elastic force (Fs) in a direction such that the cam follower (5) and the cam (6) abut each other. The cam surface (6b) is designed to have a shape such that, on the basis of first data which indicates attachment force (Fm) with respect to the distance between the attachment surface (S) and the permanent magnet (3) and second data which indicates the elastic force (Fs) with respect to the displacement of the elastic member (7), the attachment force (Fm) and the elastic force (Fs) are balanced in directions orthogonal to the cam surface (6b).
