Abstract
A flange device using a voice coil motor and a contact control method thereof are disclosed. In the flange device, a force sensor, displacement sensor and an inertial measurement unit (IMU) are used to sense contact data, the contact data is filtered, and the filer contact data is calculated based on an attitude & heading reference systems (AHRS) algorithm, to obtain a force control command to control a displacement direction and a displacement distance of the flange device, so that the flange device is able to adjust a contact status between a polishing device and a to-be-polished object by using the voice coil motor, thereby achieving the technical effect of providing an electromagnetic contact-state adjustment device with quiet and precise control and fast response.
