基材信息在线检测及喷码系统设计

摘要

基材是汽车内饰件的重要组成部分,长久以来其质量检测依靠人工抽检,效率低,精度差.本文针对基材质量检测过程中的1问题,开发在线检测及喷码系统.系统采用激光位移传感器实现两路厚度测量,PLC采集厚度数据并控制报警装置,皮带秤和称重仪表PT650D实现重量采集,上位机软件通过串口与下位机通信,实现数据处理,保存,查询,统计及其他数据库管理.为了便于质量追踪,系统给每块基材设置并喷印一个编号,并且可以打印厚度,重量等不规则信息,实现了信息实时喷印.%The substrate is an important part of automotive interior trinuThe quality inspection has long been depending on sampling inspection, which has low efficiency and precisionAccording to the existed problem of substrate measurement, it develops an online measurement for substrate and code-spurting system.The system measures the thickness through two channels using laser displacement sensors.PhC collects data and controls the alarm device.Weighting is completed by belt scale and weighing instrument PT650D;Upper-computer software communicates with slave computer through serial interface.It not only realizes data processing and storage function, but also can make database get managed such as data query, statistics and so dn.In order to make it convenient for quality tracing,the system sets and prints a number for each block.It also can print irregular information such as thickness and weight and realize real time printing.
