[0003] Patent 1 Patent No. CN112816495A discloses a car tire appearance detection system, including a frame, a centering mechanism is arranged on the frame for centering the tires; a transmission positioning mechanism is arranged on the frame for centering the tires Transmission and positioning; the identification mechanism is set on the frame and cooperates with the transmission and positioning mechanism to identify the tires by taking pictures ; This invention can complete the fully automatic appearance inspection of tires without relying on human intervention; however, it can only detect one side of the tire, and it needs to be turned over, which undoubtedly increases the detection time
[0004] Patent 2 Patent No. CN108982545A discloses a tire appearance detection method, the principle is that the first multi-axis motion mechanism drives the fixing device to pick up and fix the tire to be tested; the second multi-axis motion mechanism drives the camera to move to the tire to be tested When the camera moves to the pattern surface or side of the tire to be tested, the fixing device drives the tire to be tested to rotate, and the camera shoots the rotating tire to be tested to obtain the tread pattern or side pattern; the invention It can realize the automatic detection of tires, improve the detection efficiency and detection accuracy, and then overcome the defects of repeated operations and definition problems in tire detection in the prior art, which are difficult, slow and inefficient; but the surface of the tire is a complex curved surface , it is necessary to timely adjust the light supplement and focus of the detection equipment, and also consider the influence of ambient light on the detection results
[0005] In addition, most of the tire appearance inspections at home and abroad are manual inspections, which are inefficient and take a long time; the existing devices operate at relatively high temperatures for a long time, which causes the inspection equipment to heat up, and it is easy to burn parts due to excessive temperature

Abstract

The invention relates to the technical field of tire detection, and relates to a tire appearance detection device and a method of use thereof. A rotating assembly and a driving assembly are arranged on both sides above the frame, and two rotatable detection assemblies are arranged on the side of the rotating assembly. The detection assemblies are respectively Corresponding to the inner and outer surfaces of the tire; the advantages of using this tire appearance inspection device: the use of ring-shaped LED lights can make the light supplement of the inspection device more uniform, and the synchronous operation of the rotating table and the translation seat can be realized by switching parts, and the simplex operation of the rotating table can be realized. switch back and forth between them to adapt to different detection requirements; the image sensor is used to collect images multiple times, and two frames of images are continuously collected at a time, and the difference operation of the two frames of images is used to eliminate the influence of ambient light; the driving component is used to realize the tire fixed, and at the same time can control the stable rotation of the tire.

Description

technical field [0001] The present invention relates to a tire appearance inspection device and its use method, in particular to an appearance inspection device that simultaneously collects and compares images of the inner and outer surfaces of the tire by adding a detection component, and the method for operating the tire appearance inspection device of the present invention Instructions. Background technique [0002] The demand for tires continues to increase, and tires can generally be divided into two categories: bias-ply tires and radial-ply tires. The scope of tire appearance inspection includes: lack of rubber, bead width and narrowness, exposed lines or air pockets in the tire, surface air bubbles, heavy skin, damage, cracks, patterns, cavities, uneven tires, steel ring deformation, delamination, and tread rubber Edges, bulges, mechanical damage, toe out edge, missing parts, etc. [0003] Patent 1 Patent No. CN112816495A discloses a car tire appearance detection sy...
