Application of Machine Vision in Tire Inspection for Car Industry

With the development of transportation and the improvement of people's living standards, cars have become one of the commonly used means of transportation for families. Tires are important components of cars, directly in contact with the ground and the car suspension to cushion the shocks encountered during driving, ensuring good ride comfort and smooth driving.

However, defects inevitably occur in the production process of car tires, including appearance defects, dimension measurement, character recognition, etc., which affect the quality of the product. In order to ensure product quality and maintain manufacturer reputation, many manufacturers conduct quality inspections on finished tires, and machine vision inspection is widely used. What quality issues of tires can machine vision detect?

Applications of machine vision inspection

Dimension measurement: measurement of important dimensions such as thickness contour, total width, shoulder width, and middle width of the tire section;

Rim joint inspection: joint overlap, gap, misalignment, leakage, incorrect material, etc.;

Finished tire roundness and dimension measurement: roundness of tire tread, tire width, tire diameter and other dimension measurements;

Finished tire appearance defect detection and character recognition: bulging, pits, scratches, cracks, tire production cycle, tire specifications and model, brand logo, etc.

It can be seen that machine vision measurement is widely used in tire inspection.

Principles of machine vision inspection

The machine vision character detection system converts the tire into an image signal through an industrial camera, which is transmitted to the image processing system, and is transformed into digital signals based on pixel distribution and brightness information. The image processing system then performs calculations on these signals to extract the target features for judgment and comparison, realizing automated recognition and production inspection.

Intelligent, automated, digital, and informational are the future trends of manufacturing.
