视觉检测系统具有哪些优势?能够帮助企业解决哪些难题?

浏览量
  想必很多人对视觉检测系统都有一些基本的了解,视觉检测系统利用工业相机将被检测的物品转换成图像信号,根据像素分布、亮度和颜色等信息转变成为数字化的信号,进而对该物体进行有效的判断。那么视觉检测系统究竟帮助企业解决了哪些难题,在实际生产的过程中又有哪些不可取代的优势呢?
  Presumably, many people have some basic understanding of the visual inspection system. The visual inspection system uses industrial cameras to convert the detected objects into image signals, and converts them into digital signals according to the pixel distribution, brightness and color information, and then makes effective judgment on the object. So what problems has the visual inspection system helped enterprises solve and what irreplaceable advantages are there in the actual production process?
  1.精确性
  Accuracy
  由于人眼有物理条件的限制,在精确性上机器有明显的优点。 即使人眼依靠放大镜或者显微镜来检测产品,机器仍然会更加精确,因为他的精度能够达到千分之一英寸。
  Due to the limitation of physical conditions of human eyes, machines have obvious advantages in accuracy. Even if the human eye relies on a magnifying glass or microscope to detect the product, the machine will still be more accurate, because its accuracy can reach one thousandth of an inch.
  2.重复性
  Repeatability
  机器可以以相同的办法重复完成检测工作而不会感到疲倦。与此相反,受生理和心理的影响,人眼每次检测产品时都会感觉细微的不同,即使产品是完全相同的。
  The machine can repeat the test in the same way without getting tired. On the contrary, affected by physiological and psychological factors, the human eye will feel slightly different every time it detects the product, even if the product is identical.
  3.速度
  Speed
  机器能够更快地检测产品。特别是当检测高速运动的物体时,比如说生产线上,机器能够提高生产效率。
  Machines can detect products faster. Especially when detecting high-speed moving objects, such as production lines, machines can improve production efficiency.
  4.客观性
  Objectivity
  人眼检测还有一个致命的缺陷,就是情绪带来的主观性,检测结果会随工人心情好坏产生变化,而机器没有喜怒哀乐,检测的结果自然非常可观可靠。
  There is also a fatal defect in human eye detection, which is the subjectivity brought about by emotions. The detection results will change with the mood of workers, but the machine does not have joy, anger, sadness and joy, so the detection results are naturally very considerable and reliable.
  5.成本
  Cost
  由于机器比人快,一台自动检测机器能够承担好几个人的人物。而且机器不需要停顿,不会生病,能够连续工作,所以能够极大地提高生产效率。
  Because machines are faster than people, an automatic detection machine can take on several people's characters. And the machine does not need to stop, will not get sick, can work continuously, so can greatly improve the production efficiency.
  6.无损性
  Non destructive
  对于某些测量类型的项目,原有的测量方式是需要塞规,或者治具来对产品进行测量。但是机器视觉可以做到无损测量,产品放置在一个地方即可通过图像测量出尺寸。
  For some types of measurement items, the original measurement method is to need plug gauge or fixture to measure the product. However, machine vision can achieve non-destructive measurement, the product can be placed in a place to measure the size of the image.
  机器视觉的应用范围包括了安全系统、表面检测、定位、二维测量比较、二维码识别、二维位置定位、二维物体识别、光学字符识别、机器人视觉、交通监视和驾驶辅助系统、三维测量比较、三维物体定位、三维物体识别、特征检测、完整性检测、颜色检测、一维码识别、印刷检测等等。由于机器视觉应用范围如此广泛,所以越来越多的企业采用机器视觉检测设备代替传统的人工检测,可检测功能有以下几个方面:
  The application scope of machine vision includes safety system, surface detection, positioning, two-dimensional measurement comparison, two-dimensional code recognition, two-dimensional position positioning, two-dimensional object recognition, optical character recognition, robot vision, traffic monitoring and driving assistance system, three-dimensional measurement comparison, three-dimensional object positioning, three-dimensional object recognition, feature detection, integrity detection, color detection, one-dimensional Code recognition, printing detection and so on. Due to the wide application of machine vision, more and more enterprises use machine vision inspection equipment to replace the traditional manual detection. The detection functions include the following aspects:
  1.垂直检测功能

  视觉检测系统可以减少人力,节省人工成本,并大幅降低人为检测错误,进而提高工作效率,提升产品出货品质,增强产品的竞争力。如果进一步将视觉检测系统运用于生产管制流程上,在生产线生产产品的同时,进行生产线产品品质监控,不仅可以减少原料的浪费,而且可以进一步有效地管控生产时间。
  Visual inspection system can reduce manpower, save labor costs, and greatly reduce human detection errors, so as to improve work efficiency, improve product delivery quality, and enhance the competitiveness of products. If the visual inspection system is further applied to the production control process, the production line can not only reduce the waste of raw materials, but also effectively control the production time.
