A Multi-Microprocessor-Based Control System for Assembly of Electronic Components

Abstract Design experiences of a project on building a multi-microprocessor-based automation control system for the assembly of electronic components is reported in this paper. The control system consists of four subsystems, which are the supervisory controller, the visual pattern recognition system, the display unit and the servo system. The emphasis was put on the design of a fast, cost-effective visual information-processing unit. For this, a new type of frame grabber together with noise-insensitive image processing algorithms are incorporated by employing the TMS 4161 dual ported memory. To verify the proposed design concepts, an experimental control system is developed and applied for the semiconductor die-bonding machine.
