石英晶片外观缺陷自动分选控制技术研究

摘要

Quartz wafer appearance of defects automatic sorting system uses ARM processor as the master controller, by controlling the stepper motor to achieve the robotic arm trays and a drum of control. ARM and PC are used to realize the localization and separation of quartz crystal. Between the ARM controller and PC data transmission using USB bus interface, significantly improve the operating speed. Proven, the subject of precise control of the appearance defects of the quartz wafer sorting, quartz crystal appearance defects sorting control system for the promotion of research quartz crystal wafer sorting equipment in China is of great significance.%石英晶片外观缺陷自动分选系统使用ARM处理器作为主控制器，通过控制步进电机来实现对机械臂、料盘和出料桶的控制。采用ARM与PC机相结合的方式对石英晶片进行定位和分选，ARM控制器与PC机之间采用USB总线接口方式进行数据传输，显著提高了运行速度。经验证，本课题实现了对石英晶片自动分选设备的精确控制，其研究成果对于推动我国石英晶片自动分选设备的国产化具有重要的意义。
