Flying Vision System Design of Placement Machine for Microphone

In order to achieve high speed and precision placement function, the flying vision system based on rotating mirror is proposed, the mirror is driven to rotate by the power drawn from the nozzle rise and fall movement through a rack and pinion mechanism, the nozzle pick and place functions is not interfered by mirror through designing the rack and pinion mechanism parameters. The vision system can capture an static clear chip image when the mirror rotated to a 45\(^{\circ }\) position referenced with horizontal position, the center position and rotating angle of chip is fast calculated by the fine and coarse Hough Transform Algorithm, the center location and angle will be corrected by the control system during the mounted head is flying to placement position. The experimental results show that the system can obtain high-quality microphone chip image, the chip’s center position and rotating angle correction algorithm can meet the high-speed placement requirements.
