AI Technical Summary

Technical Problem

Traditional glass translucent scribing processing methods suffer from low processing efficiency due to frequent start-stop and position switching of the galvanometer, and color differences and splicing marks are prone to appear in adjacent areas, making it difficult to meet the needs of high-precision and high-efficiency industrial production.

Method used

The device employs a full laser-transmitting scribing system, which includes a frame, a transmission mechanism, a positioning and adsorption mechanism, a laser processing system, and a linkage drive mechanism. It uses a linear motor to drive the galvanometer scanning and the gantry beam assembly to move stepwise. Combined with real-time correction by a CCD positioning camera, it achieves continuous scribing processing and is equipped with a follow-up dust extraction mechanism to remove dust.

Benefits of technology

It significantly improves processing efficiency, eliminates splicing marks and color differences, ensures product appearance consistency, and the transmission mechanism design avoids damage to the glass surface, resulting in a significant improvement in processing quality and yield.

Abstract

This application proposes a fully laser-guided translucent scribing device. The device includes a frame, a transmission mechanism, a positioning and adsorption mechanism, a laser processing system, and a linkage drive mechanism. The transmission mechanism achieves contactless loading and unloading of glass via lifting rollers; the positioning and adsorption mechanism uses a vacuum platform to adsorb and fix the glass, eliminating deformation; the laser processing system uses a linear motor to drive a galvanometer for scanning; the linkage drive mechanism coordinates all components to complete the processing through a continuous operation mode of "galvanometer scanning one line → gantry beam driving the glass to step one line." Compared to traditional static splicing processes, this device significantly improves processing efficiency, and through precision control and CCD positioning to eliminate splicing marks, coupled with contactless transmission and follow-up dust extraction design, it effectively ensures the stability of processing quality.
