Title:
METHOD FOR MANUFACTURING MULTI-AXIAL INERTIAL FORCE SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/097440
Kind Code:
A1
Abstract:
In the present invention, before a base (128) is assembled, the sensitivities of a plurality of sensors (104, 105, 131, 132) respectively disposed on a plurality of blocks (102, 103, 129, 130) are inspected. In an inspection step, the plurality of blocks that the plurality of sensors are respectively disposed on are prepared. The plurality of blocks are fit into a plurality of main axis groove parts (224) of a main axis tray (212) and are made to touch main axis positioning surfaces of the plurality of main axis groove parts, and this results in the thickness direction of the main axis tray and the main axes of the sensors being parallel. The main axis tray is placed on a turn table (231) such that the rotation center axis of the turn table and the thickness direction of the main axis tray are parallel and the rotation center axis of the turn table and the main axes of the plurality of sensors are parallel. The sensitivities of the main axes of the plurality of sensors are inspected through the rotation or oscillation of the turn table.
