Glass processing platform and method for processing glass

Abstract

Provided are a glass processing platform and a method for processing glass. The platform comprises: a bearing platform for directly bearing glass and provided with a plurality of first through holes; a first vacuum suctioning device which comprises a base, a plurality of supporting rods with one end fixed on the base, a vacuum sucker arranged on each of the other ends of the supporting rods, and first vacuum lines connected to each vacuum sucker; a lifting device for forming a height difference between a suctioning face of the vacuum sucker and a bearing face of the bearing platform, and for removing the height difference after the vacuum sucker suctions the glass so that the suctioned face of the glass is in the same horizontal plane as the bearing face of the bearing platform. The supporting rods are arranged in the first through holes and pass through the bearing platform; and the vacuum sucker can move downward or be elastically deformed downward when subjected to a downward pressure from the glass.

Description

technical field [0001] The invention relates to the field of display device manufacturing, and more specifically, to a glass processing platform and a method for processing glass. Background technique [0002] In the current liquid crystal panel manufacturing field, due to the need for high-precision and stable fixing of the glass, the absorbable carrier is widely used in the bearing and fixing of the glass. [0003] In order to ensure the flatness of the stage and the stability of the fixed glass, a concave suction cup or suction hole is usually set on the surface of the rigid and flat stage, and it is connected to the vacuum pipeline inside the stage. When the glass substrate is placed on the stage , by forming a vacuum between the glass substrate and the stage to achieve the purpose of fixing the glass substrate. Schematic diagram of the principle of adsorbing glass on the stage figure 1 and figure 2 As shown, a suction hole 201 is provided on the surface of the stage...

AI Technical Summary

Problems solved by technology

[0004] Due to the complexity of the liquid crystal panel manufacturing process, the liquid crystal panel glass 700 will inevitably have irregular warping (such as figure 2 As shown), as the size of the glass 700 increases, the magnitude of this warping also increases, which can easily lead to the inability to establish a vacuum in the stage area corresponding to the warped position of the glass, thus causing the stage 200 to absorb and fix the glass 700 failed

[0005] In the process of absorbing and fixing the glass on the current stage, the failure to establish the vacuum of the stage due to glass warping frequently occurs. At this time, personnel are often required to manually press the warped part of the glass to re-establish the vacuum of the stage, which seriously affects the production of the equipment.
