A device for detecting the weakening effect of a laser weakening hole in an automobile instrument panel

Abstract

This utility model discloses a device for detecting the weakening effect of laser-weakening holes in automotive dashboards. It is used for high-precision, rapid, and non-destructive testing of the weakening effect of laser-weakening holes. The device includes a testing platform, a fixture, a host computer controller, a sensor lifting mechanism, a light sensor assembly, a light source assembly, and a light source lifting mechanism. The automotive dashboard is mounted on the testing platform via the fixture. The light sensor assembly is mounted on the sensor lifting mechanism and located above the laser-weakening hole; the height of the light sensor assembly is adjusted by the sensor lifting mechanism. The light source assembly is mounted on the light source lifting mechanism and located below the laser-weakening hole; the height of the light source assembly is adjusted by the light source lifting mechanism. The light sensor assembly includes multiple individual sensor units, and the outline of all the sensor units arranged in the same shape matches the outline of the laser-weakening hole. The outline of the light source assembly also matches the outline of the laser-weakening hole.
