【摘要】 产品质量检测是企业多个生产阶段必要的流程,例如从初始阶段的原材料检测、制造过程中的半成品检测,成品包装前的检测等。在目前的薄膜晶体管液晶显示屏(TFT-LCD)模块制造过程中,大量的检测任务依然依靠人员的手工测试、运算和统计,效率低下。其原因在于当前客户需求多样化、个性化,多样的产品、多变的特性,由此会产生多样的测试需求。传统的检测设备,使用者较难对其进行修改,缺乏灵活性,即使设备厂商预先设计了较多可能的测试项目,但仍难以满足用户多样化的需求。不但如此,随着信息化的深入,对测试信息有效利用,发掘深层次问题,也是测试的要求之一。而传统测试设备往往是不尽如人意的。本文结合企业的实际生产需求和现有设备状况,通过虚拟仪器和GPIB总线协议,设计出较好满足生产需求的,变更灵活的测试设备。本文结合冷阴极荧光灯管(CCFL)的测试详细说明了基于LabVIEW、GPIB总线和带有GPIB接口的数字万用表的测试系统解决方案,其将数据采集、数据记录、数据分析这三个原本分别依靠手工独立完成的检测工序结合在一起完成,使原本需要大量人力和时间完成的原材料检测工作得以迅速、准确的完成,在实际应用中取得了较好的效果。更多还原

【Abstract】 Product quality inspection is a necessary process in most companies. For example, raw material inspection in initial stage, semi finished articles inspection in process, finished goods inspection before shipment. In current TFT-LCD module assembly working process, inspection job always relies on manual test, calculation and statistic, which is unefficient. The reason is customers’ requirements are varies and individual. A great many products with various speciality requires various inspection demands. However, traditional equipments are not so flexible for users to improve. Though equipment vendor has designed quite more test programs in it, various demands are not fulfilled yet. Furthermore, with information technology developed more and more rapidly, one of inspection targets is to effectively utilize inspection result to find out more potential problems. Traditional equipments can not realize it.Considering the actual production and equipments status, this paper is to design a flexible test equipment to meet production requirements by virtual equipment and GPIB bus. On the foundation of LabVIEW, GPIB, magnetic meter with GPIB interface, this paper describes a test system integrated with CCFL test. Data collection, record and analysis, which were manually individually executed will be combined together. This test system can fleetly and correctly finish the inspection job. It has greatly improved the test performance after application.更多还原
