Substrate edging control mechanism and method for liquid crystal display module production

Abstract

The invention relates to the technical field of substrate edge grinding mechanisms, and particularly discloses a substrate edge grinding control mechanism and method for liquid crystal display module production, the substrate edge grinding control mechanism comprises a positioning seat assembly, a mechanical arm is fixedly connected to the position, close to the back face, of the top of the positioning seat assembly, and a positioning conveying assembly is installed at the bottom of the mechanical arm; a suction assembly is installed on the inner side of the positioning conveying assembly. The positioning base assembly comprises a positioning base. When the air suction assembly and the air suction port assembly are matched to enable the interior of the adsorption tank to be in a negative pressure state, the height of the lifting block is monitored through the lifting tank, and due to the fact that the interior of the adsorption tank is in the negative pressure state, if a substrate making contact with the adsorption tank cracks, gas enters the adsorption tank, and the air pressure in the adsorption tank returns to normal; at the moment, the height of the lifting block is decreased, if the suction assembly does not perform gas injection work, it is indicated that the substrate cracks at the moment, and it is convenient to rapidly detect whether the substrate cracks or not.
