Development of micro-assembly machine using linear motors

Abstract

Micro-assembly technology has been widely investigated. In the paper, a microassembly machine is developed to assembly the rubies into watch mainplate and its control system is developed. In the design, a griper with capillary force is designed to pick up the micro-objects, and linear motors are used in the micro-assembly to realize precision x-y interpolation motion because of their high precision, high efficiency and simple structure. In order to improve the accuracy of the linear motors, parameters of linear motors are tuned and compensation scheme is investigated to reduce the influence of the linear encoder systems. The experimental results show that the developed micro-assembly machine deliver high performance.
