TECHNICAL FIELD
[0001] The present application relates to the field of tire manufacturing technology, in particular to a tire internal defect detection device. BACKGROUND
[0002] In modern automobile industry, the quality of tires is directly related to driving safety and vehicle performance. Therefore, tire internal defect detection has become a common concern of domestic and foreign tire manufacturing enterprises. Traditional tire internal defect detection methods mainly rely on manual visual inspection, X-ray detection, ultrasonic detection and other technologies. However, these methods have many limitations and cannot meet the needs of modern tire production for efficient, accurate and safe detection.
[0003] Manual visual inspection is the earliest detection method, which mainly relies on the vision and experience of the detection personnel to identify the internal defects of the tire. This method has the disadvantages of low efficiency, poor accuracy, high labor intensity, etc. The detection speed is slow and cannot meet the needs of large-scale production; the detection personnel are greatly affected by subjective factors, and false negatives and false positives are easy to occur; the detection personnel are prone to fatigue after long-time work, which affects the detection quality.
[0004] X-ray detection technology penetrates the tire with X-rays to obtain the internal image of the tire and detect internal defects. Although this method can detect some internal defects, it also has problems such as high equipment cost, complex operation, radiation risk, etc. The X-ray equipment is expensive and has high maintenance cost; it needs professional technicians to operate and maintain; it has certain radiation risk to the environment and operators, and strict protective measures need to be taken.
[0005] Ultrasonic detection detects internal defects by ultrasonic propagation and reflection in the tire. Although this method has certain detection accuracy, it also has problems such as high technical level requirement for detection personnel, slow detection speed, limited application range, etc. The detection result is greatly affected by the technical level and experience of the operator; it cannot realize rapid detection, which affects the production efficiency; the detection effect on some types of defects is not good.
[0006] In recent years, some automatic detection devices have been developed to improve detection efficiency and accuracy. However, the existing technology still has some shortcomings, such as limited detection range, poor adaptability, and detection accuracy to be improved. It cannot cover all areas inside the tire; it is not adaptable to different specifications and types of tires; in some cases, the accuracy of the detection result is still not high enough. Therefore, developing a new type of tire internal defect detection device can overcome the shortcomings of the existing technology, realize efficient and accurate detection of tire internal defects, and has important practical application value.
