Abstract

The invention provides a non-destructive measurement device for skin and a non-destructive measurement method. The device comprises a horizontally extending working platform, electric lifting devices,an electric lifting device, a bracket, a product tray, laser sensors and a display, wherein the electric lifting devices are fixed on the working platform; the bracket is fixed on the working platform and includes a vertically extending upright column and a cross beam horizontally extending from the top end of the upright column; the product tray is horizontally installed above the working platform through the electric lifting devices, the product tray extends below the cross beam and is provided with a scanning hole; the laser sensors are respectively fixed on the upper and lower ends of theproduct tray through the bracket; and the display is in signal connection with the laser sensors and used for displaying measurement data in real time. According to the non-destructive measurement device and method provided by the invention, the minimum thickness of the bottom of a skin V-shaped characteristic groove can be accurately measured under the premise of ensuring that the product is notsubjected to any damages, the working efficiency of bottom thickness measurement of the skin characteristic groove is improved, and the enterprise cost is saved, thereby having good popularization and application prospects.

Description

technical field [0001] The invention relates to the field of measuring the slush plastic skin of an automobile interior instrument panel, and more particularly relates to a non-destructive measuring device and a non-destructive measuring method for the skin. Background technique [0002] The slush plastic skin of some instrument panels of automotive interior parts adopts a false stitching structure, which can be divided into two types: single stitching and double stitching. The feature groove of the product crosses the weakening line of the airbag area or is too close to the weakening line of the airbag area. If the thickness is too thin, it will easily lead to the risk of blasting failure when the airbag explodes. Therefore, the thickness of the characteristic groove of the slush-plastic skin is related to safety performance, and the thickness of the bottom of the characteristic groove needs to be monitored. . The current detection methods are all destructive measurements ...
