Abstract

The invention discloses a method for cutting a liquid crystal display panel. The method comprises the steps of providing a control device, an image recognition device and a tool, wherein a substrate is provided with all cutting positions, in a first cutting direction, of the tool, and cutting position information indicating all the cutting positions is preset in the control device; arranging reference alignment marks on the substrate, wherein the reference alignment marks are located between every two adjacent cutting positions; shooting the reference alignment marks through the image recognition device, and generating reference positional information indicating the reference alignment marks; controlling the tool to move to the cutting positions in sequence for cutting through the control device according to the reference positional information and the cutting position information. By means of the cutting method, the cutting process can be simplified, and cutting efficiency can be improved.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal panel manufacturing, in particular to a method for cutting a liquid crystal panel. Background technique [0002] In the manufacturing process of liquid crystal panels, it is necessary to cut the entire substrate to separate liquid crystal panels that meet the design size. Each liquid crystal panel to be formed on the substrate has an alignment mark. CCD (ChargeCoupled Device) recognizes the alignment mark and generates cutting control information, and the cutter cuts according to the cutting control information. The part cut by the knife is called waste. In the prior art, in the same cutting direction (for example, vertical or horizontal), after the tool completes a cut, the machine needs to forward the substrate to a position that can be scanned by the CCD, and then the CCD recognizes the second set of alignment again Mark to control the tool to continue the second cut. This leads to...
