Liaowang 1.0 Tempered Glass Inspection System

Online Flatness and Optical Distortion Measurement for Tempered Glass

Liaowang 1.0 is an online inspection system for tempered glass production lines, measuring flatness, optical power and dimensional data after tempering to support real-time quality control.

Measured Parameters

Quantitative inspection for flatness, bow and optical distortion

The system measures wave bow, overall bow, edge lift, Optical Power (OP value), flatness by peak-to-valley value (PV value), and glass length and width online.

01

Optical Power

OP value quantifies optical distortion and supports objective assessment of image distortion after tempering.

02

Flatness PV

PV value evaluates surface flatness and helps identify small surface variations.

03

Edge Lift

Edge lift detection helps evaluate installation and in-use performance risk.

04

Overall Bow

Longitudinal and transverse overall bow can be monitored across the glass sheet.

05

Length and Width

Online dimensional measurement provides production-line size data for downstream processing.

How the System Works

Vision-based measurement on horizontal tempering lines

A high-speed camera and software vision system capture surface images, calculate wave profiles and derive flatness and optical power parameters for quality evaluation.

01Capture surface images with the optical vision system
02Calculate wave profiles for downstream analysis
03Display OP and PV values for front, middle and rear sections
04Judge results against user-defined quality criteria and issue alarms when limits are exceeded

Real-time data display

Operators can review measured parameters visually and respond when flatness or optical distortion falls outside the configured limits.

Graphical Result Analysis

Surface maps, scan-line curves and production data in one inspection workflow

The system presents measured glass quality through graphical displays that make deformation trends, local anomalies and parameter changes easier to evaluate.
