Design of a Micro-hole Array Device for Picking the Micro Lenses

Abstract

Lenses are widely used in many areas mostly in mobile cameras and security cameras. Before installation, inspection is very important to check the lenses condition like dust particles and any other damages. lenses are very sensitive and easy to scratch when using clamping device to pick up lenses. So, we use vacuum to provide suction to pick up the lenses to avoid wear and scratches. In this study, combined servo motor with EDM to create micro-hole array, to place the lenses. User interface helps the user to control the XY-Table for exact coordinate location to make fine hole array. In the experiment, it shows that by adjusting the gap voltage, pulse on-time, pulse off-time and outlet water pressure, the machining speed can be controlled without reaming and scorching. The average error during machining operation to make a micro-hole array is 0.00405 mm. User interface application save a lot of time and helps to improve accuracy to make fine hole.
