Abstract

The utility model relates to a breaking glass fixture. The fixture is a plate body provided with an open slot, the inner surfaces of the two sides of the open slot are parallel to each other, the two sides of the open slot have the same thickness, and the thickness of the plate body is three times of the thickness of the side of the open slot. The breaking glass fixture disclosed by the utility model is designed for the breaking glass, so that an operator easily breaks the glass having the width less than or equal to the width of glass leftover materials, and the forces applied to both sides of the breaking glass can be more consistent and symmetrical, thereby significantly reducing the probability of occurrence of the glass edge defects (micro-edge cracking, edge breakage or corner breakage). When the operator is skillful in breaking the glass, even the occurrence of the glass edge defects, such as micro-edge cracking, edge breakage or corner breakage is completely avoided to ensure the edge quality of the sensor glass, thus the flexural and impact strength of the glass are enhanced.

Description

A kind of glass sliver fixture

Technical field

The utility model relates to a kind of glass sliver fixture, can effectively be applied to sliver common or the glass edge corner material of chilled glass after laser cutting (laser scribing).Use the utility model to carry out the sliver of glass edge corner material, the fine fisssure limit of a glass edge that can make to have split slice, collapse the defect factors that Huo Beng angle, limit etc. can cause strength of glass to reduce and reduce to minimum, when operator's sliver gimmick is skillful, even can avoid these fine fisssure limits completely, collapse the generation of the glass edge defects such as Huo Beng angle, limit.

Background technology

Since the listing of the Apple iPhone mobile phone of 2007 and release iPad panel computer in 2010, driven smart mobile phone and panel computer flourish.Only approximately 100,000,000 7 thousand ten thousand of the sales volumes of global smart mobile phone in 2008, but be increased to 700,000,000 to the sales volume of global smart mobile phone in 2012, the shipment amount of grinding regulating mechanism IDC prediction global intelligent mobile phone in 2015 will reach 1,400,000,000.Panel computer global marketing amount is increased to 1.16 hundred million in 2012 by 1,800 ten thousand in 2010 especially, grinds regulating mechanism Gartner prediction panel computer whole world shipment amount in 2014 and will reach 2.6 hundred million.

The iPhone mobile phone of Apple is that global First adopts G/G(Glass/Glass) smart mobile phone of structure condenser type touch-screen, because being adopts capacitance induction principle to design touch-screen, therefore be easy to realize the function of multi-point touch, make touch-screen can have more essence application, and make man-machine interface more friendly and more directly perceived, easy to operate.Under the leading of the iPhone of Apple smart mobile phone and iPad panel computer, drive the flourish of G/G structure capacitive touch-screen industry, even if capacitive touch screen has other new change on structure and material over nearly two, three years, but G/G structure capacitive touch-screen still occupies an important position in whole touch-screen field.

In simple terms, G/G structure capacitive touch-screen is by protective glass (cover glass), optical cement, sensing glass (sensor glass) and FPC(flexible printed circuit board) institute form.For making portable mobile device can reach light and thin object, it is the sheet glass of 0.4mm, 0.55mm, 0.7mm or 1.1mm that sensing glass generally adopts thickness, because glass belongs to friable material, so the glass that capacitance plate sensor uses generally all can be through chemical enhanced to increase strength of glass.In addition, the quality of glass edge quality has very critical impact to strength of glass, so in the time carrying out this procedure of glass cutting, adopt laser cutting can significantly reduce glass edge fine fisssure limit, collapse the generation of the defects such as Huo Beng angle, limit, and then promote the quality of glass edge.After laser cutting, need to carry out the operation of manual glass sliver, the quality of sliver quality (fine fisssure limit, collapse the edge defects such as Huo Beng angle, limit) is very large on the impact of strength of glass again.

As shown in Figure 1, in glass substrate size, 355.6mm × 406.4mm has 28(7 × 4) typesetting of individual sensing glass, after use laser cutting paints line, glass can be broken is cleaved into seven block length bars, and then sequentially glass sliver is broken and split from centre, finally can be left with the only sensing glass of 14.81mm scrap stock of width, as shown in Figure 2.

Because the width of glass edge corner material is only surplus less than 15mm, the bad application of force of personnel when this causes manual sliver, in the time of glass sliver, the right and left application of force is uneven or asymmetric, just easily there is fine fisssure limit, collapse the defects such as Huo Beng angle, limit in glass edge, these edge defects can cause strength of glass to reduce and not resistance toly falling of making that glass becomes, not shock-resistant.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple and effective glass sliver fixture is provided.

The technical solution of the utility model is as follows:

A kind of glass sliver fixture, for slotted plate body is set, the internal surface of two sides of fluting is parallel to each other; Two lateral thickness of fluting are the same, and the thickness of plate body is the lateral thickness of three times of flutings.

As preferably, plate body comprises three epoxy glass fiber cloth veneer sheets that thickness is identical, wherein, upper plate is identical with lower plate length, middle plate be shorter in length than upper plate and lower plate, upper plate, middle plate, lower plate are bonded as to plate body successively, form take middle plate as bottom land the fluting that upper plate, lower plate are side.

As preferably, the position below fluting, glue and is bound plate, middle plate, lower plate by adhesive tape, strengthens fixing.

As preferably, the degree of depth of fluting is less than 25mm.

The beneficial effects of the utility model are as follows:

The utility model system designs for glass sliver problem, make operator in the time carrying out the sliver of the little glass edge corner material of width, it is easier to operate, the right and left application of force can be more consistent and symmetrical, thereby significantly reduce the Probability of glass edge defect (fine fisssure limit, collapse Huo Beng angle, limit), when operator's sliver gimmick skillful, even can avoid these fine fisssure limits completely, collapse the generation of the glass edge defects such as Huo Beng angle, limit, guarantee sensing glass edge quality, and then promote the counter-bending and resistance to impact shock of glass.

When little for scrap stock width (in order to make the utilization ratio of glass substrate reach best, the width of dead space scrap stock can not be greater than 20mm conventionally) sheet glass problem, the utility model proposes a simple and easy but very effective sliver fixture, can facilitate personnel's glass sliver operation, and the probability that the glass edge defect after sliver (fine fisssure limit, collapse Huo Beng angle, limit etc.) can be occurred drops to minimum.
