Tire defect detection data calibration device and method

Abstract

The invention relates to a tire defect detection data calibration device and method. The tire defect detection data calibration device comprises a tire, an attachment mechanism is installed on the tire, the attachment mechanism is provided with a hook and an elastic hook-and-loop fastener, the hook is of an integrally-formed structure, a rectangular frame is arranged at one end of the hook and used for being connected with the elastic hook-and-loop fastener, the elastic hook-and-loop fastener is provided with a hook face and a loop face, the loop surface is connected with the hook, and the hook surface is connected with the calibration block. The device solves the problem that the current data calibration form is inconvenient to work by pasting adhesive tape and a single calibration block, can conveniently and quickly calibrate tires and data images, can quickly match tires of various sizes and types through several combinations, and through the existing checkerboard arrangement layout, solves the problem that the manual combination of checkerboards is irregular and the calibration block is low in precision.

Description

technical field [0001] The invention relates to the technical field of tire detection, in particular to a tire defect detection data calibration device and method. Background technique [0002] In order to improve the production quality and safe service life of motor vehicle tires, a series of online testing items are required in the manufacturing process. For example, X-rays are used to detect defects in the inner layer of tires, and the signals generated by the rays passing through the tires are fed back to be imaged on the receiving device, thereby verifying whether there are performance defects such as faults, air bubbles, and steel wire breaks inside the tires, and according to the inspection results. Tires are identified and graded. [0003] In the existing tire defect detection device or method, the tire to be detected is placed vertically on the conveying line, and the X-ray tube is driven to extend into the slit for ray imaging. Due to the heavy weight of tires, s...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of tires, such as various engineering tires, truck tires, etc., the tires placed on the conveyor line will be partially deformed to a certain extent due to their own weight, which directly affects the accuracy of the detection data.

Calibration of tire detection data was a cumbersome task before, especially after the tire was found to be non-linear in X-ray imaging, the requirements for calibration have also increased
