摘要

为了提高设备智能化作业，节省人力，对彩色滤光膜微观缺陷自动化修补进行了研究。通过最小循环比对法，修补设备能实现自动查找缺陷、确认缺陷精确位置并自行选择研磨、激光或填色等修补作业方式的功能，替代人工角色。经统计，自动修补成功率为99.8%，与人工修补成功率99.9%接近，满足生产需求。8.5代线CF工厂自动化修补导入后，该岗位人员配置由20人降低为7人。进一步地，通过赋予检测设备给基板判级功能，使不需要修补的基板不进入修补设备，优化了基板流向和设备负荷。优化后，BM、RGB和PS修补工序平均修补一个卡夹的时间分别减少了24%、12%和6%，提升了修补效率。

Abstract

In order to improve the intelligent operation of the equipment and save humannel

the automatic repair of microscopic defects of color filter was studied. By using the method of minimum cycle comparison

the repair equipment can automatically find defects

confirm the exact position of defects and choose the repair operations such as tape

laser or ink

so as to replace the human role. According to the statistics data

the success rate of automatic repair is 99.8%

closing to 99.9% by manual repair

which meets the requirement of production. After the automatic repair is introduced in 8.5-generation CF factory

the post staffing is reduced from 20 to 7. Furthermore

by endowing the detection equipment with the function of judging the substrates

the substrates that do not need to be repaired will not enter the repair equipment

which optimizes the flow direction of the substrates and the load of the equipment. After optimization

the average repair time of BM

RGB and PS repair time for one cassette decreases by 24%

12% and 6%

respectively. The repair efficiency is improved.
