Method for longitudinally cutting side board of liquid crystal glass base plate

Abstract

The invention relates to a method for longitudinally cutting a side board of a liquid crystal glass base plate. The method comprises the steps of clamping the liquid crystal glass base plate by a tooling plate clamping claw, transporting to a longitudinal cutting station, clamping the liquid crystal glass base plate by a front leaning part and a rear leaning part of a longitudinal cutting machine, opening the tooling plate clamping claw, longitudinally cutting the side board of the liquid crystal glass base plate from top to bottom by knife flywheels at two sides of the longitudinal cutting machine, restarting the clamping claw to clamp the liquid crystal glass base plate after cutting, opening a sealing strip of the front leaning part of the longitudinal cutting machine, breaking off the glass base plate through suction cups at two sides of a cutting board strip of the rear leaning part of the longitudinal cutting machine, resetting the knife flywheels at two sides of the longitudinal cutting machine after the glass base plate is broken out, opening the suction cups at two sides of the cutting board strip of the rear leaning part of the longitudinal cutting machine, and transporting the broken liquid crystal glass base plate to the next station by a conveyer belt. The upward pulling force of the claw to the glass base plate is reduced and the glass base plate is prevented from breaking during cutting; and besides, only the sealing strip of the front leaning part is loosened during breaking off, so that the liquid crystal glass base plate is prevented from being scratched because of contacting with the longitudinal cutting machine during breaking off.

Description

technical field [0001] The invention belongs to the field of processing and manufacturing liquid crystal glass substrates, and in particular relates to a method for longitudinally cutting side plates of liquid crystal glass substrates. Background technique [0002] In the manufacturing process of liquid crystal substrate glass, the overflow-drawn glass plate is cut and broken into single pieces by a cross-cutting machine, hung on the semi-finished conveyor belt, and then sent to the slitting station for longitudinal cutting of the side plates on both sides , forming the initial glass substrate. For the glass substrate of the sixth-generation production line, its length is about 2 meters, its width is about 1.6 meters, and its weight is about 5000 grams. Up and down or left and right movement occurs during transportation, which makes it impossible to cut after arriving at the slitting station. In order to ensure stable clamping, increasing the clamping force will easily caus...

Problems solved by technology

[0003] In the current cutting method, the glass substrate will be subjected to an upward pulling force due to the clamping of the three jaws. The front and rear leans on the slitting machine clamp the glass substrate, so that the glass substrate is subjected to a pressure, and the cutter wheels on both sides cut the edge of the glass substrate longitudinally. The glass substrate is also subjected to a cutting pressure when the board is cut, and the three external forces are superimposed, which may easily cause the glass substrate to be chopped and split. scratch
