AI Technical Summary

Technical Problem

Existing technologies are prone to poor detection results when inspecting glass substrates with curved surfaces or uneven surface grinding due to interference from reflected light.

Method used

Design a glass substrate surface defect detection device. By adjusting the components and supporting the components, the detection module is made to correspond to the area to be tested on the glass substrate. The device includes the cooperation of columns, balls, slide rails and round heads. The angle of the detection module is automatically adjusted to adapt to curved surfaces or unevenly ground surfaces.

Benefits of technology

It effectively reduces the reflective effect caused by curved surfaces or uneven grinding, improves the reliability and applicability of the test, and is suitable for flat and curved glass substrates or glass substrates with uneven grinding.

Abstract

The application relates to the field of substrate detection devices, and discloses a surface defect detection device and a detection method for a glass substrate, wherein the detection device comprises a shell and a detection module for defect detection; a conveying module for conveying the glass substrate is arranged on the shell; an adjusting assembly movably attached to the conveying module is arranged on the shell; and a supporting assembly for supporting the detection module is arranged on the adjusting assembly. Through cooperation between the shell, the supporting assembly and the adjusting assembly, the detection module can be tilted to adjust the angle, so that the detection module is in direct correspondence with the to-be-detected area of the glass substrate. After the direct correspondence is formed, the influence of the reflection caused by the arc surface or uneven grinding can be effectively reduced, the detection effect of the detection module can be further ensured, and the detection result is reliable. The device can be applied to the existing plane glass substrate, and the effect is better when the device is applied to the glass substrate with the arc surface or the unevenly ground surface.
