Disclosure of Invention

The invention aims to provide a double-knife cutting technology application to solve the problems that when double-layer glass is cut for LCD screens, cutter wheels with the same specification are used, if the specification is only suitable for cutting adhesive glue positions, the cutter wheels are not suitable for cutting non-adhesive positions, otherwise, the cutter wheels are the same, defects often occur during cutting, the yield is not high, and loss in the manufacturing process is increased.

In order to achieve the purpose, the invention provides the following technical scheme: the double-knife cutting technology is applied and comprises a glass substrate, wherein the glass substrate comprises first glass and second glass, the positions of the first glass and the second glass correspond to each other, adhesive glue materials are bonded on the left side and the right side between the first glass and the second glass, the glass substrate is cut through a knife flywheel A and a knife flywheel B, the knife flywheel A cuts the glass substrate into a first cutting track, and the knife flywheel B cuts the glass substrate into a second cutting track.

Preferably, the cutter wheel angle of the cutter wheel A is 115-130 degrees.

Preferably, the cutter wheel angle of the cutter wheel B is 90-105 degrees.

Preferably, the glass substrate has a thickness of 0.05mm to 1 mm.

Compared with the prior art, the invention has the beneficial effects that:

1) the position of the adhesive glue material is cut through the cutter wheel A, the position of the non-adhesive glue material is cut through the cutter wheel B, the yield is obviously improved after glass is cut, and the loss caused in the manufacturing process is greatly reduced;

2) the cutter wheels with different specifications are arranged on the same cutter heads, so that synchronous cutting is performed, and the quality after cutting is improved.
