Tire internal defect detection method based on X-ray

Abstract

The invention provides an X-ray-based tire internal defect detection method, which comprises the following steps of S1, obtaining a tire X-ray image, and performing image preprocessing; s2, segmenting the preprocessed image in the step S1, and extracting a traveler region image; s3, training a target detection neural network model; s4, inputting the traveler region image obtained in the step S2 into the training model in the step S3, and performing defect positioning and classification; s5, outputting a defect result; according to the invention, the quality defect of the position of the steel wire ring in the tire can be quickly detected, and the radial tire defect automatic detection system suitable for the production state is formed, so that the production quality of the tire is ensured, and defective products are prevented from flowing out.

Description

technical field [0001] The invention relates to a tire internal defect detection method, in particular to a tire internal defect detection method based on X-rays. Background technique [0002] With the increase of domestic car ownership year by year, people pay attention to the driving safety of the car. As an important component of the car, the quality of the tire directly determines the safety of the car. In order to avoid the quality problems inside the tire However, it brings safety hazards to the driving of automobiles, and the quality inspection of tires before leaving the factory has become a key production link required by automobile manufacturers. Since the inside of the tire cannot be inspected intuitively, how to detect the internal structural quality of the tire more accurately has become the focus and difficulty of the current inspection. [0003] The current non-destructive testing mainly includes ultrasonic, magnetic particle and X-ray testing. The first two ...

Since the inside of the tire cannot be detected intuitively, how to detect the internal structure quality of the tire more accurately has become the focus and difficulty of the current detection

[0003] The current non-destructive testing mainly includes ultrasonic, magnetic particle and X-ray testing. Due to the limitation of materials, the former two have poor imaging and testing effects under tire materials.

However, X-ray inspection cannot detect defects in the traveler part, resulting in a decline in product quality
