Fully Automated Circuit Board Online Inspection System

摘要:

为了降低检测成本，同时提高电路板的检测效率和准确率，设计了一种全自动化电路板检测系统。该系统在不改变现有生产线的情况下，能轻松对接电路板生产线，实现成品电路板质量检测的全自动化，并且可以接入工厂的FIS系统，实现了对产线的全面改造升级。系统选用工控机和ADLINK PCI-7432 IO卡来构成主控硬件平台；在Qt软件开发环境下完成主控机软件的开发，控制接驳台、机械手和ICT检测箱协调工作，完成对电路板的全自动检测。为了适配不同的电路板生产线，提高系统的通用性，该检测系统允许人工配置产线信息。经过电路板生产厂家的实际应用，该系统运行可靠稳定，与传统的人工检测方法相比自动化检测速度为比人工快1倍，误检率为0.2%，大大提高了生产效率，降低了生产成本。

Abstract:

In order to reduce the detection cost and improve the detection efficiency and accuracy of the board, a fully automated circuit board inspection system is designed. The system can easily dock the circuit board production line without changing the existing production line, realize the full automation of the finished circuit board quality inspection, and can be connected to the FIS system of the factory to realize the comprehensive transformation and upgrade of the production line. The system selects IPC and ADLINK PCI-7432 IO card to form the main control hardware platform; completes the development of the main control software in the Qt software development environment, controls the coordination station, the robot and the ICT detection box to coordinate the work, complete the circuit board Fully automatic testing. In order to adapt to different circuit board production lines and improve the versatility of the system, the detection system allows manual configuration of production line information. Through the practical application of the circuit board manufacturer, the system runs reliably and stably. Compared with the traditional manual detection method, the automatic detection speed is 1 times faster than the manual, and the false detection rate is 0.2%, which greatly improves the production efficiency and reduces the production cost.
