Glass plate edge grinding device

Abstract

The invention discloses a glass plate edge grinding device, comprising: a bottom frame; a spindle motor assembled on the bottom frame; a grinding wheel coupled to a rotating shaft of the spindle motor, a grinding point contacting the edge of a glass plate; a first nozzle , located on the upper part of the glass plate, and rotatably disposed on the outer circumference of the grinding wheel and coupled to the bottom frame; a second nozzle located at the side of the glass plate, and rotatably disposed on the outer circumference of the grinding wheel and coupled to the bottom frame; a rotary nozzle driving portion capable of rotating the first and second nozzles along the outer peripheral portion of the grinding wheel independently of the grinding wheel; and a grinding water supply portion configured to supply the grinding water to the first and second nozzles. When the grinding wheel performs grinding along the edge of the glass plate, a grinding water spray nozzle is rotated to the appropriate position and the grinding water injection point is determined, so as to perform grinding when the grinding water supply device is not disturbed by the grinding wheel.

Description

【Technical field】 [0001] The invention relates to a glass plate edge grinding device. 【Background technique】 [0002] In the manufacturing process of LCD (Liquid Crystal Display), AMOLED (Active Matrix Light Emitting Display) display, solar cell (solar cell) and other products, glass substrates are generally used as equipment. After the manufacturing process is completed, the glass substrate formed on the glass substrate The boards of the corresponding size are cut and disassembled, and the cut edge parts are ground, and the edge parts are inspected after grinding. [0003] In the edge grinding process in this process, the grinding wheel is rotated at a predetermined rotational speed while contacting the edge portion of the glass plate for grinding. During this process, if the grinding surface is continuously ground due to high heat generated by friction, cracks are likely to occur on the grinding surface. In order to solve such a problem, the grinding water can be supplie...

AI Technical Summary

Problems solved by technology

[0009] In order to compensate for the twisting of the grinding water injection pipe, a hollow spindle motor with a hollow formed in the center of the spindle motor is used, and a hose is connected through the hollow, but the price of the hollow spindle motor is high, and the length of the spindle is long, which leads to Another problem that deteriorates the quality of grinding is the vibration problem that occurs with the rotation of the grinding wheel
