Substrate taking mechanism capable of preventing glass substrate from deforming

Abstract

The invention discloses a substrate taking mechanism capable of preventing a glass substrate from deforming. The substrate taking mechanism comprises a square mounting plate, wherein four suction cupassemblies distributed in a rectangle are mounted at the four vertex corners of the lower end of the square mounting plate, the upper ends of the four suction cup assemblies are jointly connected withan air exhaust connecting assembly, the upper ends of two suction cup assemblies located on the same diagonal line of the square mounting plate are jointly provided with a size adjusting assembly, the outer side of each suction cup assembly is connected with a traction assembly, and a mounting connecting piece is fixed to the center of the upper end of the square mounting plate. When the glass substrate is taken out, the four suction cup assemblies can suck the glass substrate from the four vertex corners, after the glass substrate is sucked, the traction assembles are started, supporting vertical pipes are pulled outwards, and the four supporting vertical pipes are pulled outwards at the same time, so that the glass substrate is straightened, buckling deformation of the periphery of theglass substrate can be prevented, and depressed deformation of the center of the glass substrate can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of glass processing, in particular to a plate taking mechanism for preventing deformation of a glass substrate. Background technique [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, seriously ...
