Automatic laser detection device and method for automobile curved glass

Abstract

The invention provides an automatic laser detection device and method for the automobile curved glass. The device comprises a first conveyor belt which is mounted on a work station and is used for disposing and conveying the glass workpiece, a refrigeration jet unit used for cooling an upper surface of the glass workpiece on the first conveyor belt, a heating jet unit used for heating the upper surface of the glass workpiece conveyed from the refrigeration jet unit to form a fog layer, and a laser detection unit used for performing laser scanning detection of the fog layer. The device is advantaged in that the fog layer formed on the upper surface of the curved glass is scanned and detected, detection data with high precision is outputted, the detection speed is fast, efficiency is high, the detection data is accurate, the obtained detection data of the workpiece is accurate, a detection omission phenomenon is avoided, and the qualified workpiece after detection is guaranteed to be consistent with assembling requirements.

Description

technical field [0001] The invention relates to an automatic device, in particular to a laser automatic detection device and a detection method for curved surface glass of an automobile. Background technique [0002] The traditional detection of automotive curved glass is to preset multiple detection points on the glass surface, and to roughly determine whether the glass surface is For qualified parts, most of them are only conducted by random inspection, and it is impossible to conduct all inspections on curved glass. The inspection method is backward, and the measurement efficiency is low. Point-based inspections may easily lead to missed inspections of defective products. [0003] Automobile glass is generally a transparent curved surface shape, and the light source is prone to total reflection on the transparent glass. Laser detection realizes its function through the reflection of the light source. If most of the laser light is transmitted or fully reflected, it will be...

[0002] The traditional detection of automotive curved glass is to preset multiple detection points on the glass surface, and to roughly determine whether the glass surface is For qualified parts, most of them are only carried out by random inspection, and it is impossible to carry out all inspections on curved glass. The inspection method is backward, and the measurement efficiency is low. Point-taking inspections may easily lead to missed inspections of defective products.

[0003] Automobile glass is generally a transparent curved surface shape, and the light source is prone to total reflection on the transparent glass. Laser detection realizes its function through the reflection of the light source. If most of the laser light is transmitted or fully reflected, it will be reflected back to the laser head. The luminous flux is reduced, and the laser head will not be able to detect accurate results
