A turntable is rotatably connected to the top of the frame, and a glass plate is placed on the turntable. An installation frame is fixedly installed at the rear end of the frame. Chutes are arranged on both sides of the turntable on the frame. Threaded rods are rotatably connected in the two chutes. Slide seats are fixedly installed at the tops of the two threaded rods. Moving frames are fixedly installed at the tops of the two slide seats. Sliders are slidably connected in the two moving frames. Second cylinders are fixedly installed on the mutually remote sides of the two moving frames. The output ends of the two second cylinders are respectively fixedly installed on the corresponding sliders. This liquid crystal screen glass edge grinding machine can simultaneously perform edge grinding on both sides of the glass plate, reducing the operation steps in edge grinding processing, thereby further improving the processing efficiency of edge grinding. Moreover, it can drive the glass plate to rotate by using the turntable to adjust the side to be ground, avoiding the need for manual handling and flipping, thus greatly reducing the labor intensity of workers.
