Method and device for cutting glass of liquid crystal display screen

Abstract

The invention discloses a method and a device for cutting glass of a liquid crystal display screen for solving the problems of breakage or poor saw-teeth at an intersection of cutting tracks in different directions in the cutting process of the liquid crystal display screen. The method comprises the following steps: performing first cutting on a first surface of the glass of the liquid crystal display screen along a first direction by a cutter wheel and forming multiple first cutting tracks on the glass of the liquid crystal display screen; performing second cutting on the first surface of the glass of the liquid crystal display screen along a second direction by the cutter wheel, enabling the cutter wheel to rise to a jumping height vertical to the glass of the liquid crystal display screen and enabling the cutter wheel at the jumping height to drop after moving for a distance which is sum of the cutter outgoing distance and the cutter incoming distance along the second direction and carry on cutting in the second direction until multiple second cutting tracks are formed on the first surface when the distance between the cutter wheel and each first cutting track in the second cutting process meets with a cutter outgoing distance, wherein the second direction is vertical to the first direction.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a method and device for cutting glass of a liquid crystal screen. Background technique [0002] In the production process of the liquid crystal cell of the liquid crystal panel, the large piece of liquid crystal screen glass after the box needs to be cut and split into individual liquid crystal cells, and then the liquid crystal is fed into the liquid crystal, pressed and sealed to complete the preparation of the liquid crystal cell. In the LCD glass cutting process, the cutter wheel needs to cut in the X direction and the Y direction on the same side of the LCD glass. For example, the X direction is cut first to form the X direction cutting marks, and then the Y direction is cut. Such as figure 1 As shown, the X-direction of the liquid crystal screen glass 1 has been cut in advance to form cutting marks. When the cutter wheel 2 cuts the liquid crystal screen glass 1 in the...
