Title:
GRIPPING HEAD, GRIPPING SYSTEM AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/177408
Kind Code:
A1
Abstract:
A gripping head(1), a gripping system and a gripping method are disclosed. The gripping head(1) including a holding device(10) for applying holding force to a first part(P1), an acoustic pressure measurement device(11) for measuring a first acoustic pressure level of a first acoustic wave(W1) propagating from the first part(P1) resulted from a second acoustic pressure of a second acoustic wave(W2) ex-erted by an acoustic transducer against the first part (P1) held by the holding device (10), and a controller(12) for judging a contact of the first part(P1) with an second part(P2) using the measurement of the first acoustic pressure level output from the aco-ustic pressure measurement device(11). It is possible to detect contact of assembly p-arts(P1,P2) by measuring the acoustic pressure level of acoustic wave(W1,W2) tran-smitted from the gripped assembly part(P1,P2).
