A plate taking mechanism for preventing deformation of glass substrate

Abstract

The invention discloses a plate taking mechanism for preventing deformation of a glass substrate, comprising a square mounting plate, suction cup assemblies installed at the four corners of the lower end of the square mounting plate, the four suction cup assemblies are distributed in a rectangular shape, and the upper ends of the four suction cup assemblies share a common There is an air extraction connection component connected, and the upper ends of the two suction cup components located on the same diagonal line of the square mounting plate are jointly installed with a size adjustment component. The outside of each suction cup component is connected with a traction component. pieces. When taking out the glass substrate, the four suction cup assemblies can absorb the glass substrate from the four corners. After the glass substrate is absorbed, the traction assembly is activated to pull the support standpipe outward, and the four support standpipes are pulled out at the same time. Pulling outwards can straighten the glass substrate, which can not only prevent warping and deformation around the glass substrate, but also effectively avoid concave deformation at the center of the glass substrate.

Description

Technical field [0001] The present invention belongs to the field of glass processing, and more particularly to a plate mechanism that prevents deformation of the glass substrate. Background technique [0002] The TFT-LCD (LCD) glass substrate production process is a spillation pull-down method, that is, the glass substrate is out of the annealing furnace, and the cross cutting machine is cut into a predetermined size, and the conveyor is sent to the lower process by longitudinal control. The semi-finished area is stored on the conveyor belt on the conveyor tape, and the rear processing area is reused using the plate robot to put the glass substrate on the Cache on the Glass substrate to the grinding brush, taking the plate, machine hand In the middle of the suction cup adsorption glass substrate, it can cause warpage deformation around the glass substrate, and severely affect the quality of the glass substrate. Inventive content [0003] It is an object of the present invention...

AI Technical Summary

Problems solved by technology

[0002] The production process of TFT-LCD (liquid crystal display) glass substrate is the overflow down-draw method, that is, after the glass substrate flows out of the annealing furnace, it is cut into a specified size by a cross-cutting machine, and then sent to the next process by a conveyor belt after being processed by a slitting machine. In the semi-finished product area, the board-taking robot collects glass substrates from the conveyor belt and stores them on the buffer A-frame. In the post-processing area, the plate-taking robot puts the glass substrates on the buffer A-frame into the grinding brush belt. When taking the board, the robot arm The suction cup absorbs the middle of the glass substrate, which will cause warping and deformation around the glass substrate, which will seriously affect the quality of the glass substrate
