SYSTEM OF 2D CODE DETECTION AND THICKNESS MEASUREMENT FOR GLASS SUBSTRATE, AND METHOD OF THE SAME

摘要

PURPOSE: A system and a method for 2D code detection and thickness measurement of a glass substrate are provided to enable free measurement of the entire glass substrate by a contactless method for measuring the thickness of a glass substrate. CONSTITUTION: A system for 2D code detection and thickness measurement of a glass substrate comprises a loading/unloading unit(100), a washing unit(200), a measuring unit(300), and a mounting unit(40), and a measuring terminal(400). The loading/unloading unit loads and unloads a glass substrate(20). The washing unit washes the glass substrate. The measuring unit detects 2D code of the glass substrate and measures the thickness thereof. The mounting unit is rotated b y a central rotary shaft(30). The measuring terminal automatically controls the operation of the mounting unit. The measuring terminal calculates the thickness of the glass substrates and detects the 2D code.
