Abstract

This invention discloses a laser speckle tyre lossless detector. The detector is located in the test room of the vacuum device and is connected with a vertical and level and rotation laser speckle probes through test moving structure. Under the test prove there is tyre automatic position device to supporting and positioning and there is door in the sidewall of the test room. This invention also provides a method for lossless test and the laser speckle tyre loss detector can test the inner defection of the products and can be used in quality test of space flight field.

Description

Technical field [0001] The invention belongs to tire non-destructive testing technology, and particularly relates to a laser speckle tire non-destructive testing instrument and a method for non-destructive testing using the same. Background technique [0002] There are usually two methods for nondestructive testing of tires using laser technology, one is laser holographic tire nondestructive testing technology, and the other is laser speckle tire nondestructive testing technology. Laser holographic tire non-destructive testing technology is a technical method used in the 1990s to detect the internal quality of tires. It uses a coherent laser, applies the principle of holographic interference, and detects the inner surface of the tire by means of vacuum loading and double exposure to detect internal defects such as delamination and air bubbles. Due to the characteristics of holographic interference technology, firstly, the laser source is required to have ...
