X-ray detection method and full-automatic detection equipment for engineering tires

Abstract

The invention discloses an X-ray detection method and full-automatic detection equipment for engineering tires. The method comprises the step of detecting the interior of a tire to be detected in an X-ray protection chamber by virtue of a ray tube and an imaging sensor, and specifically comprises the following steps of: mounting the tire on a carrier vehicle on rails outside the ray protection chamber, and moving the vehicle to a preset position in the protection chamber and closing a protection door when the tire is mounted on the vehicle, wherein the tire bearing part of the vehicle is a tire rotating mechanism consisting of multiple rollers; and starting a tire centering mechanism and the tire rotating mechanism, rotating the tire on the rollers of the tire rotating mechanism, adjusting the tire to an accurate detection position through the centering mechanism, starting the imaging sensor and the X-ray tube to preset positions for detection, and displaying and storing detected images in a computer. The method has the advantages that the size of the X-ray protection chamber is reduced, and the construction cost is reduced; the tire rotates stably, and thus the imaging precision is improved; radial run-out caused by concave and convex parts of the excircle of the tire is prevented; and moreover, radiation during manual operation is eliminated.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a method and equipment for X-ray detection of tires. Background technique [0002] The use of X-rays has been widely used in the production and inspection of tires. Due to the large size of large-scale engineering tires and the harsh environment of use, more stringent inspections are required in production. [0003] At present, most of this kind of testing equipment is to hold up the tire by two or four shafts that can be rotated on the lifting mechanism, and suspend it in the air for testing. For example, Chinese patent application number 200810016571.9, the applicant is Qingdao University Software Holding Co., Ltd., the name is "tire X-ray detection device and its method" disclosed such as image 3 As shown in the structure, "the tire X-ray detection device and its method adopt a centered detection mode in which the tire is hung vertically, and the detected tire rotates at a ...

AI Technical Summary

Problems solved by technology

The rotating and oscillating mechanism of the X-ray receiving device drives the signal detector to rotate along the sidewall, tread, and sidewall direction of the detected tire in order to receive X-ray signals. The disadvantages are: (1) The equipment is huge and the cost is high. ;(2) It takes up a lot of space; (3) The operation is cumbersome and complicated; (4) The installed capacity is large and the power consumption is high; (5) The detection cycle is long
