Dual-cutter cutting machine for liquid crystal glass and cutting method

Abstract

The invention discloses a dual-cutter cutting machine for liquid crystal glass and a cutting method. The dual-cutter cutting machine for the liquid crystal glass comprises a stander, a worktable surface, positioning plates, cutting knife rests and cutting knife heads, wherein the worktable surface is arranged on the stander, the positioning plates arranged on the worktable surface, the cutting knife rests are mounted on the positioning plates, and the cutting knife heads are mounted on the cutting knife rests; the positioning plates include an upper positioning plate and a lower positioning plate, the upper positioning plate is arranged on the worktable surface, and the lower positioning plate is arranged under the worktable surface; the cutting knife rests include an upper cutting knife rest and a lower cutting knife rest, the upper cutting knife rest is mounted on the upper positioning plate, and the lower cutting knife rest is mounted on the lower positioning plate; the cutting knife heads include an upper cutting knife head and a lower cutting knife head, the upper cutting knife head is mounted on the upper cutting knife rest, the lower cutting knife head is mounted on the lower cutting knife rest, and the upper cutting knife head and the lower cutting knife head are correspondingly arranged at upper and lower positions. By virtue of an upper-lower dual-cutter cutting manner, an upper layer of glass sheet and a lower layer of glass sheet of a liquid crystal display screen are simultaneously cut, and the upper layer of the glass sheet and the lower layer of the glass sheet are uniformly cut and are extremely precisely aligned, so that the production efficiency is greatly improved, and the rate of good products is greatly increased.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a liquid crystal glass double-knife cutting machine. [0002] The invention also relates to a cutting method of a liquid crystal glass double-knife cutting machine. Background technique [0003] The overall size of LCD screens is generally determined by upstream manufacturers. If you need a specific size LCD screen, you need to open a mold together with the upstream. The cost of R&D and mold opening is very high, which is unacceptable to most customers. Liquid crystal glass is the main substrate material used in liquid crystal displays. Manufacturers at home and abroad cut out the required size of liquid crystal displays by cutting the existing liquid crystal glass. The current process is to use a glass cutting blade to physically cut the liquid crystal glass. [0004] Since the glass sheet of the liquid crystal display (abbreviated as liquid crystal glass) is divided into upper and lower la...

AI Technical Summary

Problems solved by technology

Using the traditional single-blade cutting method to cut LCD screens is less efficient, and requires extremely high alignment of the upper and lower glass sheets of the LCD screen, and the yield rate is low; the requirements for the operator's technical proficiency are also extremely high. Moreover, in the process of flipping, the glass on the cut side is easy to crack and cause liquid crystal leakage.
