Background

Rolling bearings are indispensable in various systems and apparatuses, and tapered roller bearings are commonly used in support systems due to excellent bearing capacity and motion effect. The inner assembly of the tapered roller bearing comprises an inner ring, a retainer and a rolling body. The rolling body is an important part for realizing the rotation of the bearing, is uniformly distributed between the inner ring and the outer ring, and the loss of the rolling body directly changes the service performance and the time of the rolling bearing and can bring great damage to equipment. Therefore, the tapered roller bearing can be put on the market only after being assembled and qualified through detection, and the purpose of detection is to find out whether the rolling body is neglected to be assembled or inverted. Under the eyes, bearing manufacturers in China mainly carry out spot inspection by naked eyes, mechanical optical instruments and the like. Under the condition of large-scale production, the working efficiency is low due to the factors of overlong working time, visual fatigue and the like by a manual operation detection method, and meanwhile, the bearing cannot be disassembled when being detected, so that the detection standard is continuously widened, the conditions of neglected installation and inverted installation are further caused, and the detection difficulty is invisibly improved due to the small gap between the inner ring and the retainer, so that the omission is easily caused, and the operation difficulty is increased.

Further development of machine vision technology and image processing technology under technological progress has been promoted, and machine vision inspection systems are widely used. By replacing human detection, machine vision detection rapidly occupies the market with the advantages of high speed, high precision, low cost and low consumption. Therefore, the machine vision detection technology is adopted in the detection of the assembly defects of the tapered roller bearing rolling elements, great significance is generated in the actual market, and great driving force is generated for Chinese bearing manufacturers to realize product optimization and manufacture upgrading.
