Substrate glass cutting and grinding device

Abstract

The invention discloses a substrate glass cutting and grinding device. The device comprises a plurality of substrate cutting knife assemblies, and the plurality of substrate cutting knife assemblies are installed on pressurizing limiting plate assemblies in an elastic abutting sliding mode. The device has the beneficial effects that a top cutting air cylinder drives the substrate cutting knife assemblies to move downwards in the cutting process, at the moment, cutting knife discs on the substrate cutting knife assemblies make contact with the surface of the substrate glass, the cutting pressurizing force applied to the substrate glass during cutting of the substrate cutting knife assemblies is changed through fine adjustment of an automatic pressurizing air cylinder, and through elastic abutting of an ejecting guide sliding rod and an ejecting pressurizing spring, the knife bodies of the cutting knife discs elastically jack and move relative to plate bodies of the pressurizing limitingplate assemblies; and the knife bodies of the cutting knife discs on the multiple substrate cutting knife assemblies elastically jack and move relative to the plate bodies of the pressurizing limiting plate assemblies, during cutting, the knife bodies of the cutting knife discs on the multiple substrate cutting knife assemblies are in elastic jacking and pressing contact with a substrate glass plate, and in this way, flexible contact is achieved when the multiple substrate cutting knife assemblies make contact with the substrate glass plate.

Description

technical field [0001] The invention belongs to the technical field of substrate glass manufacturing equipment, and in particular relates to a substrate glass cutting and grinding device. Background technique [0002] Substrate is the abbreviation of thin film transistor. Substrate display is the mainstream display device on various notebook computers and desktop computers. Each liquid crystal pixel on this type of display is driven by a thin film transistor integrated behind the pixel. Therefore Substrate display is also a kind of active matrix liquid crystal display device, and it is one of the best LCD color displays. Substrate display has the advantages of high responsiveness, high brightness, high contrast, etc., and its display effect is close to that of CRT display. [0003] The existing technology has the following problems: during the cutting and grinding process of substrate glass, the cutting ability of the cutting wheel decreases after a period of use, and discon...

Problems solved by technology

[0003] The existing technology has the following problems: during the cutting and grinding process of substrate glass, the cutting ability of the cutting wheel decreases after a period of use, and discontinuous deep scribing occurs when breaking, chipping, and fragmentation occur; in addition For different thicknesses, the cutting pressure changes, resulting in different cutting depths. Usually, it is necessary to replace the cutting wheel t
