视觉缺陷检测设备应用于PCB电路板检测的优势

浏览量

  PCB的应用越来越广泛,其独特的优点包括:可高密度化、高可靠性、可设计性、可生产性、可测试性、可组装性及可维护性等等,就这决定了对其产品合格率的要求是极高的。人眼检测是满足不了的,山东红宝自动化提供的视觉缺陷检测设备能够针对PCB生产制作过程中出现的问题,定制视觉缺陷检测方案。
  PCB is more and more widely used. Its unique advantages include: high density, high reliability, designability, producibility, testability, assembly and maintainability, which determines that the requirements for its product qualification rate are very high. Human eye detection cannot be satisfied. The visual defect detection equipment provided by Shandong Hongbao automation can customize the visual defect detection scheme for the problems in the PCB production process.

PCB视觉缺陷检测


  那么,在制作PCB板的过程中容易出现哪些问题呢?
  So, what problems are prone to occur in the process of making PCB?
  1、贴片元器件在生产过程中易出现孔洞、剥落、污点等缺陷,由于缺陷小,传统算法需要耗费大量的时间对缺陷进行定制化开发,并且在进行灰度阈值分割时,易将微小的缺陷分割出去,很难保证在高速生产线上实现零缺陷检测的要求;
  1. Patch components are prone to defects such as holes, spalling and stains in the production process. Due to the small defects, the traditional algorithm needs to spend a lot of time on customized development of defects, and it is easy to separate small defects in gray threshold segmentation, so it is difficult to meet the requirements of zero defect detection in high-speed production line;
  2、PCB板上存在很多焊点和细小零件,字符识别采集图像时背景较为复杂,干扰因素多,造成字符定位和识别不准确,加上零件本身反光,会出现识别信息不全、误识别以及识别速度慢等情况,无法满足实际生产检测过程中对PCB板字符识别的需求;
  2. There are many solder joints and small parts on the PCB board. When character recognition collects images, the background is complex and there are many interference factors, resulting in inaccurate character positioning and recognition. In addition, the reflection of the parts themselves will lead to incomplete recognition information, false recognition and slow recognition speed, which can not meet the needs of PCB board character recognition in the actual production and detection process;
  3、PCB板在焊接元器件过程中,需要检测每个元器件位置是否正确、元器件是否缺失等情况,传统算法无法对多种电子元器件定位识别,而且定制开发需要耗费大量的时间,容易受外界因素影响,导致错误定位或元器件缺失,直接影响PCB板的性能及生命周期。
  3. In the process of PCB welding components, it is necessary to detect whether the position of each component is correct and whether the components are missing. Traditional algorithms can not locate and identify a variety of electronic components, and customized development takes a lot of time. It is easy to be affected by external factors, resulting in wrong positioning or missing components, which directly affects the performance and life cycle of PCB.
  山东红宝自动化制定的视觉缺陷检测方案存在以下优势:
  The visual defect detection scheme developed by Shandong Hongbao automation has the following advantages:
  1、降低成本 Reduce costs
  视觉缺陷检测生产代人眼检测,可同时检测产品的尺寸、外观缺陷等,减少工位,节首人工成本,提高生产效率
  Visual defect detection is a substitute for human eye detection, which can detect the size and appearance defects of products at the same time, reduce the labor cost of stations and sections, and improve the production efficiency
  2、减少工件损伤Reduce workpiece damage
  无需接工件便可全方位检测,减少工件的损伤
  It can be tested in all directions without connecting the workpiece to reduce the damage of the workpiece
  3、杜绝误差 Eliminate errors
  实时生产质量数据监控,相较于人工检测误差更小,杜绝产生次品,减少高昂代价的返工
  Real time production quality data monitoring, compared with manual detection, has less error, eliminates defective products and reduces costly rework
  4、准确性高 High accuracy
  对数据指标进行定量描述,避免人工主观判断失误,检测速度快,提高了生产率和分级精度
  The quantitative description of data indicators can avoid manual subjective judgment errors, the detection speed is fast, and the productivity and classification accuracy are improved
  5、稳定性好Good stability
  视觉缺陷检测出的产品确保质量稳定性,提高生产量,并优化质量,提高产品竞争力
  The products detected by visual defects ensure quality stability, improve production, optimize quality and improve product competitiveness
  6、适用各种工况环境
  Applicable to various working conditions and environments
  视觉缺陷检测可以用于人工无法适应或接的危险环境
  Visual defect detection can be used in dangerous environments that cannot be adapted or connected manually
  7、全面提高工厂智能化水平
  Comprehensively improve the intelligent level of the factory
  检测过程中生成的所有测量数据都可以进行统计和分析,并可以导出指定的测量数据生成报表
  All measurement data generated in the detection process can be counted and analyzed, and the specified measurement data can be exported to generate reports
