Abstract
The purpose of this paper is to develop an automated acoustic inspection platform for an earpiece manufacturing. An 8-pin detector has been designed to automatically locate a coil which is inside an earpiece drive. This 8-pin detector is composed of eight probes. Voltage data will be obtained by a A/D converter via scanning and reading the earpiece when the detector contacts the earpiece’s drive. The location of the coil can be ascertained from the voltage data. The automated acoustic inspection platform uses a microcontroller (PIC18F4520) to control the integrated system sequence and the actuators, including the pneumatic cylinder solenoid and the step motor drive.Developed, here, is an automated machine which moves earpieces from the plate of the earpiece to a claw. The claw, then, moves the earpiece into position to detect the coil’s location. After locating the coil using an 8-pin detector, an acoustic inspection process will be executed automatically. The time of the inspection process is about 5 seconds.
