螺母视觉检测设备之缺陷检测原理

浏览量
  看起来小小的螺母,可以说是相当的不起眼,但在任何机械设备制作的过程中都少不了螺母,其个头不大,但作用甚大。当然,螺母量产之后不经过严格的检测筛查出现残次品,会直接影响机械的正常运作,针对螺母定制的视觉检测设备能够按照执行标准筛选出有缺陷、不合格的螺母。
  It looks like a small nut, can be said to be quite humble, but in the process of any mechanical equipment production, there is no need for the nut, its size is not big, but the role is very big. Of course, the defective products will directly affect the normal operation of the machine without strict inspection and screening after mass production of nuts. The visual inspection equipment customized for nuts can screen out defective and unqualified nuts according to the implementation standards.
螺母视觉检测
  接下来就跟随红宝自动化的小编一起来看看螺母的视觉检测案例。
  Next, let's take a look at the visual inspection cases of nuts with the help of Hongbao automation.
螺母外观检测
  这是一个螺母的检测效果图通过检测设备的成像,我们可以看到清晰的外表轮廓,这个螺母,我们需要检测的内容是它的尺寸以及螺牙的缺陷还有牙与牙的距离那么有的人就会问,尺寸能检我是相信的,但是螺纹在里面,你们怎么检测,在这里我可以很负责人的告诉大家,内在的螺纹我们是可以检测的,我就会会用到一个特殊的工具:内窥镜头去完成。
  This is the inspection effect picture of a nut. Through the imaging of the detection equipment, we can see the clear external contour. The content of the nut that we need to detect is its size, the defects of the screw teeth, and the distance between the teeth. Then some people will ask, I believe that the size can be inspected, but the thread is inside. How do you detect it? I can tell the person in charge here To tell you, we can detect the internal thread, and I will use a special tool: endoscope to complete.
螺母内纹视觉检测
  通过视觉检测设备打光效果图看来,我们可以看到螺纹与螺螺纹之间的距离以及是否存在漏牙的现像。
  The distance between the thread and the screw thread and whether there is tooth leakage can be seen through the visual inspection equipment lighting effect picture.
  通过检测设备拍照出来的这个图像我们可以看到螺纹的尺寸不对,观察发现,这是一个缺少螺纹的螺母,我们称之为缺牙或者无牙,是一个NG品。
  Through the image taken by the inspection equipment, we can see that the size of the thread is not correct. It is a nut without thread, which we call missing tooth or no tooth. It is a ng product.
  通过自动检测设备这个图像,我们通过侧面打光,可以准确的看到他的一个高度。通过计算这个高度,我们也是准确的知道它是否是一个尺寸合格的产品。
  Through the automatic detection equipment of this image, we can accurately see a height of his through the side lighting. By calculating the height, we can know whether it is a qualified product.
  这就是螺母视觉检测的整体流程,又因为螺母分为各种不同的型号,外观也有所差异,所以在定制螺母视觉检测设备的时候,红宝自动化的工程师会根据具体的产品特点、外观以及形状等多方面的因素考虑,设计出合理的视觉检测设备
  This is the overall process of nut visual inspection, and because the nuts are divided into different models, the appearance is also different, so when customizing the nut visual inspection equipment, Hongbao automation engineers will design reasonable visual inspection equipment according to the specific product characteristics, appearance and shape and other factors.
