Abstract

The invention discloses a process method for preventing ITO from scratching in the cutting process, which belongs to the technical field of double-layer glass display screen processing, and particularly relates to a double-layer glass which is formed by bonding two single-layer glasses together through optical cement and the like, which is widely applied to the fields of flat panel display, liquid crystal panel, vehicle-mounted display, intelligent wearing and the like, in the prior art, the cutting pressure of cutting equipment is the same, waste edge materials are left at the position of an ITO circuit or the position of a C line after the glass is cut, if the waste edge materials are left at the position of the ITO, a person separates the waste edge materials, the risk of scratching the ITO circuit is caused, each cutting line is treated by independent cutting pressure, the thinning is more accurate, the pressure of the C line is less than that of the A line and the B line, the penetration amount of a cutting knife wheel at the position of the C line into the glass is the least, the glass is firstly broken from the A line and the B, the phenomenon that the original is uncontrollable is thoroughly improved.

Description

Technological method for preventing ITO (indium tin oxide) from being scratched in cutting process

Technical Field

The invention relates to the technical field of double-layer glass display screen processing, in particular to a technological method for preventing ITO (indium tin oxide) from being scratched in a cutting process.

Background

Double glazing, it is double glazing that two individual layer glasses pass through optical cement etc. and bond together, the field such as panel display, liquid crystal display panel, on-vehicle demonstration and intelligent dress has been used widely, wherein, when processing glass shape, often relate to special processing requirement, for example when cutting one deck or several layers of glass, the requirement remains bottom glass part, guarantee this layer to cut through when cutting one deck glass promptly, but can not destroy lower floor's glass, can not even injure the film of being pressed from both sides in the middle, in the present industry, cutting equipment's cutting pressure is the same, then behind the glass cutting, the slitter edge material remains in ITO circuit position or the position of C line, and is irregular, if remain in the ITO position, when personnel separate the slitter edge material, then have the risk of cutting off the ITO circuit.

Disclosure of Invention

The invention aims to provide a technological method for preventing ITO from being scratched in a cutting process, so as to solve the problem that when waste edge materials are separated, the risk of scratching an ITO circuit is caused in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the process method for preventing ITO from being scratched in the cutting process comprises the following steps:

step 1: putting the whole large glass block on a cutting platform, and fixing the large glass block;

step 2: A. b, C, cutting the line A, the line B and the line C of the bulk glass in the step 1 respectively by three cutting devices according to a preset program, wherein the cutting pressure of the cutting device C is smaller than that of the cutting device A and that of the cutting device B;

and step 3: and (4) taking out the glass cut in the step (2) to finish cutting.

Preferably, the cutting platform in the step 1 is provided with a sucker, and the sucker fixes the large glass.

Preferably, the bulk glass in step 1 is double-layer glass with an ITO circuit on the inner surface.

Preferably, in the step 3, the manipulator is controlled to take out the glass through the suction cup.

Preferably, the cutting pressure of the cutting device A and the cutting pressure of the cutting device B in the step 2 are the same.

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

1) according to the invention, each cutting line is independently treated by cutting pressure, so that the cutting line is more refined and accurate, the pressure of the C line is less than that of the A line and the B line, the penetration amount of the cutting knife wheel at the position of the C line into the glass is minimum, the glass is firstly broken from the A line and the B line, no scrap material is left at the position of the ITO line in a pressure difference mode, and the phenomenon that the original uncontrollable phenomenon is thoroughly improved.

2) The invention does not need to increase consumables such as mechanical tools, and the like, has simple and practical method and greatly saves cost.
