Grinding wheel automatic control method and device of glass grinding machine with self-correction function

Abstract

The invention provides a grinding wheel automatic control method and device of a glass grinding machine with a self-correction function, and relates to the field of liquid crystal display screens. Thegrinding wheel automatic control method and device of the glass grinding machine with the self-correction function use a first controller for controlling a driving motor to drive a grinding wheel ofthe glass grinding machine to grind glass according to grinding rotation control signals, use the first controller for recording the rotating number of grinding the glass by the grinding wheel of theglass grinding machine according to the grinding rotation control signals, and use the first controller for searching a control threshold and an advancement distance according to the model of the grinding wheel; and when the rotating number of grinding the glass by the grinding wheel reaches the control threshold, the first controller is used for controlling the driving motor to drive the grindingwheel of the glass grinding machine to advance to the glass by the advancement distance, so that the automatic control of the driving motor driving the grinding wheel of the glass grinding machine toadvance to the glass by the advancement distance is realized, the working efficiency of the glass grinding machine is improved, the labor control cost is reduced, and the operation experience is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display screens, in particular to an automatic control method and device for a grinding wheel of a glass grinding machine with a self-correcting function. Background technique [0002] With the continuous development of electronic technology, more and more TFT-LCD (Thin Film Transistor-Liquid Crystal Display, liquid crystal display) are widely used in various electronic products, TFT-LCD display is usually made of TFT-LCD glass substrate manufacture. The post-processing production process of TFT-LCD (liquid crystal display) glass substrate is mainly the grinding of edges and chamfers. The 4 sets of grinding wheel motors in the G1 and G2 stations of the grinding machine are controlled by their respective frequency converters. Due to the abrasiveness of the grinding wheel, under automatic conditions, the grinding amount must be manually rewritten every time 60 glass substrates are ground (about one h...

AI Technical Summary

Problems solved by technology

Due to the abrasiveness of the grinding wheel, under automatic conditions, the grinding amount must be manually rewritten every time 60 glass substrates are ground (about one hour), and the grinding feed rate cannot be automatically changed at any time. The decline of grinding quality directly affects the quality of the product

At the same time, every four hours, the grinding machine is suspended for at least ten minutes, and the technicians check the grinding quality according to the input grinding volume data. While checking, it not only reduces the equipment utilization rate, but also greatly increases the occurrence of PAC, and also increases the labor intensity.
