Needle Visual Inspection System

Needle roller appearance defect size detection solution

Can be used to detect the length of needle rolling, needle rolling, diameter, chamfering, needle rolling size visual high-speed detection, grooves and other defects.

With the development of science and technology, the demand for automation in industry is getting higher and higher. Bearings are essential parts in mechanical equipment. In the production process of bearings, there will be various defects, which have a certain impact on the quality. So far, the main method of checking bearings in many factories is manual inspection. With the continuous improvement of customers' requirements on product quality, the traditional manual inspection can no longer meet the current market demand. As a nondestructive inspection method to replace manual inspection now and in the future, machine vision automatic inspection equipment is being used more and more in the field of bearing detection.

Needle roller refers to the rotating body on needle roller bearings, mainly used in all kinds of bearings, is a roller bearing with cylindrical roller, roller like a needle thin and long, this bearing has a high load bearing capacity, compact radial structure. Due to the impact of the use environment, customers have high requirements for needle rolling detection. The optical automatic detection equipment of needle roller appearance defects is specially used for the detection of bearing needle roller, which integrates dimensions measurement, out-of-tolerance elimination and appearance detection. The device is easy to operate and fast, with a minimum detection diameter of 2mm and a maximum detection speed of 20m/min. After several customer certifications and hundreds of millions of needle rolling tests, the database contains a variety of defects, such as scratches, broken points, flat heads, and knife marks, with an accuracy of 0.01mm.

The equipment can also be used to check valve conduit, cylindrical pin and other appearance defects, to solve the problem of wrong detection, missed detection in manual detection, help customers improve the quality of testing and expand market competitiveness while saving labor costs.
