机器视觉在PCB印刷线路检测领域的应用
作者:李白 来源:北京印刷学院 时间:2018-08-28

在PCB印刷电路制造中需检查印刷线路接连线。在没有使用机器视觉检测之前,此项检查主要依赖员工肉眼在线检查。但是人工检测有很多弊端,PCB线路复杂细小,因人眼疲劳等不可抗拒因素,不仅有部份不良产品会漏检。而且长时间检查影响员工视力,导致次工位人员流失大,这一问题也是困扰很多企业的一个主要难题。

It is necessary to check the connection of printed circuit in PCB printing circuit manufacturing. Before the use of machine vision testing, this inspection relies mainly on the naked eye inspection. However, manual detection has many disadvantages. The PCB line is complex and small, because of the irresistible factors such as eyestrain,Some of the bad products will be missed. Moreover, the long time inspection affects the eyesight of the employees, resulting in the loss of the personnel in the second place. This problem is also a major problem that plagues many enterprises.

PCB机器视觉检测设备引入之后,不仅解决了上述难题,也大幅度提高了PCB印刷线路板检测的效率以及产品的良率,综合下来有如下两大优势:

After the introduction of PCB machine vision testing equipment, it not only solves the problems mentioned above, but also greatly improves the efficiency of PCB printed circuit board detection and the good rate of the product. It has the following two advantages:

1、PCB机器视觉检测设备可以自动识别不合格品,并将其捡出;高清相机能分辨识别0.01mm的细小差别;自动检查残缺断线、线宽线窄、批锋短路、异物等不良问题。

1, PCB machine visual inspection equipment can automatically identify unqualified products and pick them out; high definition cameras can distinguish and identify the small differences of 0.01mm; automatically check the defective broken line, line width and line narrow, batch front short circuit, foreign object and other bad problems.

2、员工劳动强度大大降低,流失消除;节省了检查人员,减少了产品反工工时;提升工厂在客户中的科技形象,并令其对产品质量有充分的信心。

2, the labor intensity of the staff is greatly reduced, the loss is eliminated, the inspectors have been saved, the anti labor time of the product is reduced, the scientific image of the factory in the customer is promoted, and the quality of the product is fully confident.
