Visual detection system for tire appearance

Abstract

The invention discloses a visual detection system for tire appearance. The visual detection system comprises a conveyor belt and a clamping device, and also comprises a tire front surface detection device and a tire back surface detection device which are oppositely arranged, wherein the clamping device is arranged between the tire front surface detection device and the tire back surface detection device; a mounting frame, a rotating mechanism, an inner side detection mechanism and an end surface detection mechanism are arranged in each of the tire front surface detection device and the tire back surface detection device; a circumferential surface detection mechanism is arranged in the tire front surface detection device; the rotating mechanisms are mounted on the mounting frames; and the inner side detection mechanisms, the end surface detection mechanisms and the circumferential surface detection mechanism are arranged around the rotating mechanism. Omni-directional tire detection without a dead angle is achieved; and compared with traditional manual detection and laser detection, the tire detection device has the advantages that the coverage is wider, and the detection efficiency is higher.

Description

technical field [0001] The invention relates to the field of intelligent manufacturing, and more specifically, to a visual inspection system for tire appearance. Background technique [0002] With the development of the economy, cars have played an increasingly important role in people's lives. The annual sales of passenger cars in my country will reach nearly 20 million, and the quality inspection of cars is becoming more and more important. [0003] The quality of automobile tires directly affects the safety of vehicles. The existing tire inspection is mainly through manual rolling of tires, and detection is carried out by means of hand touch and visual inspection. This method can detect defects on the outside and inside of tires, but cannot analyze the defects of tires. Outline, it takes several minutes to detect a tire, and the efficiency and quality cannot be guaranteed. [0004] The linear laser technology that appeared in the later period detects the sidewall or tabl...

[0003] The quality of automobile tires directly affects the safety of vehicles. The existing tire inspection is mainly through manual rolling of tires, and detection is carried out by means of hand touch and visual inspection. This method can detect defects on the outside and inside of tires, but cannot analyze the defects of tires. profile, it takes several minutes to detect a tire, and the efficiency and quality cannot be guaranteed

[0004] The linear laser technology that appeared in the later stage detects the sidewall or table. By irradiating the tire surface for data collection and data processing, it can detect the contour and flaws on the outside of the tire, but its detection area is limited and can only detect the outside of the tire. For tires The inner side still needs traditional manual detection, which still cannot achieve the purpose of automatic detection
