Title:
TRIAXIAL FORCE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/150993
Kind Code:
A1
Abstract:
Provided is a triaxial force detection device which is capable of more accurately detecting a load in comparison to the prior art. This triaxial force detection device (1) is provided with: a triaxial force sensor (2); a bending sensor (3); and a signal processing unit. The triaxial force sensor (2) is provided with: a strain body (21) for receiving a load (F) exerted on an object (W); an X-axis strain gauge (24) which is attached to the strain body (21), and which detects an X-axis direction force component; a Y-axis strain gauge (25) for detecting a Y-axis direction force component; and a Z-axis strain gauge (26) for detecting a Z-axis direction force component. The triaxial force sensor (2) outputs detection values (DFx, DFy, DFz) corresponding to the force components (Fx, Fy, Fz) of the load (F). The bending sensor (3) is for detecting the position where the load (F) is exerted on the object (W). The signal processing unit (4) is electrically connected to the bending sensor (3) and the triaxial force sensor (2), and calculates the X-axis direction force component, the Y-axis direction force component, and the Z-axis direction force component of the load on the basis of detection signals of the bending sensor (3) and the triaxial force sensor (2).
