  自动化生产制造过程中,必不可少的环节就是检测,检测产品的外观有没有瑕疵,尺寸有没有误差等等。而机器视觉检测系统就很好的解决了这一难题。视觉检测技术就是通过计算机模拟人眼的视觉功能,从图像中提取信息进行处理并加以分析、判断,最终用于实际检测、测量和控制。
  In the process of automatic production and manufacturing, the essential link is detection, which detects whether the appearance of the product has defects, whether the size has errors and so on. The machine vision detection system solves this problem very well. Visual inspection technology is to simulate the visual function of human eyes by computer, extract information from the image for processing, analysis and judgment, and finally use it for actual detection, measurement and control.


  PCB识别分类-视觉检测应用案例
  Application case of PCB identification, classification and detection
  本系统是专门针对PCB行业生产厂家开发,现在很多PCB打样厂商及中小批量生产商,每天样板/小批量生产款数达到了5000~10000款/天,每款PCB都是代表不同的客户,目前通过人工去识别板子上面的编号很难,因印刷的字体比较小很容易识别错误造成混料,造成大量人力损失及客户的投诉。
  This system is specially developed for manufacturers in the PCB industry. At present, many PCB proofing manufacturers and small and medium-sized batch manufacturers have 5000 ~ 10000 models / day of sample / small batch production every day. Each PCB represents different customers. At present, it is difficult to identify the number on the board manually. Because the printed font is relatively small, it is easy to identify the wrong materials, Cause a lot of human losses and customer complaints.
  检测要求:根据产品的外形及尺寸、内孔与加载到系统中产品的标准外形图进行匹配,匹配成功分数最高的则与客户打印机对接通讯,软件系统根据识别产品的编号,发送给打印机打印编号标签,检测产品尺寸:30mmx30mm~250mmx250mm,此系统通过视觉识别产品与加载产品黑白特征图中编号一一对应,防止混料。
  Testing requirements: match the product according to the appearance and size, inner hole and the standard outline drawing of the product loaded into the system. The one with the highest matching success score will communicate with the customer's printer. The software system will send the printer to print the number label according to the number of the identified product. The tested product size: 30mmx30mm ~ 250mmx250mm, The system visually identifies the product and the number in the black-and-white characteristic drawing of the loaded product one by one to prevent mixing.
  导流盘外观缺陷检测-视觉检测应用案例
  Application case of deflector appearance defect detection
  导流盘外观检测要求:导流盘背面中间压伤变形、导流盘背面中间定位销压伤变形、导流盘背面中间定位销缺少一个、导流盘中间出现发白异常、导流盘边缘出现较大磕碰伤、导流盘背面有一个凸点压伤变形、导流盘背面边缘多点小磕碰伤、导流盘定位销角度测量。
  Requirements for appearance inspection of the guide plate: the middle of the back of the guide plate is crushed and deformed, the middle locating pin of the back of the guide plate is crushed and deformed, the middle locating pin of the back of the guide plate is missing, there is abnormal whitening in the middle of the guide plate, there is a large bump on the edge of the guide plate, there is a bump on the back of the guide plate, there are many small bumps on the edge of the back of the guide plate Angle measurement of guide plate locating pin.
  导流盘胶圈检测要求:黑圈检测、是否装好、角度检测、角度测量。
  Requirements for rubber ring detection of deflector: black ring detection, whether it is installed, angle detection and angle measurement.
  生产日期、保质期字符识别-视觉检测应用案例
  Character recognition and application date
  保证生产日期等相关信息正确清晰地标注是食品生产过程中的一个重要环节。此类识别检测工作具有高度重复性,传统人工检测会给工厂增加巨大的人工成本和管理成本,检测效率低,速度慢,还无法保证100%的检验合格率。利用机器视觉技术进行OCR字符采集检测具有非常广阔的市场需求。
  Ensuring the correct and clear marking of production date and other relevant information is an important link in the process of food production. This kind of identification and detection work is highly repetitive. The traditional manual detection will add huge labor cost and management cost to the factory. The detection efficiency is low and the speed is slow, and the inspection qualification rate of 100% can not be guaranteed. Using machine vision technology for OCR character acquisition and detection has a very broad market demand.
  检测项目:生产日期、保质期等信息有无,字符漏喷码,喷码缺失,字符模糊,喷码歪斜,重影,信息有误等。
  Test items: production date, shelf life and other information, missing characters, missing characters, fuzzy characters, skew characters, ghosting, incorrect information, etc.
  除此之外,视觉检测系统在其他行业的应用范围也很广泛,例如:电子元器件检测:连接器、电容、电阻等的尺寸测量,PIN针偏移、变形、短缺等缺陷,印刷字符检测等;食品包装检测:食品包装的外观完整性检测、条码识别、密封性检测;饮料分拣与色选、液体检测,生产日期、保质期字符识别;灌装线上空瓶破损、洁净检测等;医药包装检测:医药塑料瓶、玻璃瓶的长度、高度、直径等尺寸测量,破损、黑点等缺陷检测。
  In addition, the visual inspection system is also widely used in other industries, such as electronic component inspection: size measurement of connectors, capacitors and resistors, defects such as pin offset, deformation and shortage, printed character inspection, etc; Food packaging inspection: appearance integrity inspection, bar code identification and sealing inspection of food packaging; Beverage sorting and color selection, liquid detection, production date and shelf life character recognition; Detection of bottle damage and cleanliness above the filling line; Inspection of pharmaceutical packaging: measurement of length, height, diameter and other dimensions of pharmaceutical plastic bottles and glass bottles, and inspection of defects such as damage and black spots.
