PCB电路板通电前自动化检测平台设计

电路板(PCB)承载着多种电子功率元器件的信息,在各种智能化的机械设备中得到广泛的使用,随着各种集成技术的不断提高,越来越普遍,产品的工艺要求水平也是在不断的严格,多层电路板的集成也是到处可见,密度集成化的产品正在朝着更高水平的方向去发展。如何自动检测PCB电路板是高度自动化设备生产车间的一个难题,本次研究主要是针对PCB板在生产完成之后进行一系列的通电前检测,提高了自动化设备生产的效率,大大降低了生产周期。本文是基于在上位机与下位机485通讯的基础上,提供了一种较为完善的PCB出厂前一系列自动检测方案。

The circuit board (PCB) carries information of various electronic powercomponents and is widely used in various intelligent mechanical devices. Density-integrated products are moving toward higher levels. How to automatically detect PCB circuit board is a difficult problem in the production workshop of highly automated equipment. This research is mainly for a series of pre-energization tests after the completion of production of PCB board, which improves the efficiency of automation equipment production and greatly reduces the production cycle. This paper is based on the communication between the upper computer and the lower computer 485, and provides a more complete automatic detection scheme for the PCB before leaving thefactory.
