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.
Next, let's take a look at the visual inspection cases of nuts with the help of Hongbao automation.
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.
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.
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.
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.
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.
