Tire surface feature detection system and method

Abstract

The invention discloses a tire surface feature detection system which comprises a first detection device, a second detection device, a third detection device and a rotating device. The rotating device comprises two rollers parallel to each other and a motor used for driving the rollers to rotate, the first detection device, the second detection device and the third detection device are all arranged between the two rollers, the first detection device is used for detecting the surface features of the front face of a tire, the second detection device is used for detecting the surface characteristics of the side surface of the tire, and the third detection device is used for detecting the surface characteristics of the tire shoulder. The invention discloses a tire surface feature detection method. By the adoption of the method and device, errors caused by manual judgment can be reduced, the probability of repeated on-line replacement detection of the tires is reduced, the recognition degree of on-line detection of the repeatedly-used tires in the motor vehicle detection field is improved, and therefore the safety risk factors influenced by continuous on-line driving of the scrapped tires are eliminated.

Description

technical field [0001] The invention relates to the field of tire detection, in particular to a tire surface feature detection system and method. Background technique [0002] The main function of the pattern of automobile tires is to increase the friction between the tread and the road surface, remove water, and prevent the wheels from slipping. Under the action of braking force and lateral force), the pattern can produce large tangential elastic deformation. As the tangential force increases, the tangential deformation increases, and the "friction effect" of the contact surface is also enhanced, thereby inhibiting the tendency of the tread and the road to slip or slip. This largely eliminates the disadvantages of non-patterned (smooth tread) tires that are easy to slip, making the car performance related to the friction performance between the tire and the road surface - power, braking, steering and driving safety. Normal performance has a reliable guarantee. [0003] T...

Problems solved by technology

[0003] The existing tire wear measurement method generally adopts the method of visual inspection. This method evaluates people's intuitive judgment, and the human factor is very large, so the accuracy cannot be guaranteed.

Another method of measuring tire wear is to measure the tread depth. This method is mainly performed by the inspector using a tire tread depth gauge for contact measurement. Due to the operation method of the inspector and the error of the tire tread depth gauge itself, the measurement will be incorrect. Large errors occur in the data, and the manual measurement efficiency is low, which seriously restricts the work efficiency of the automobile inspection line
