Description
Technical field
The present invention relates to curved surface 3D touch screens and flat-faced screen glue attaching process.
Background technology
In the 3D touch screen glues fitting of the mobile terminals such as mobile phone, since glass cover-plate is curved surface, so box dam glue makes
Expect that the shape as bend glass is difficult with common technique；Make profiling jig scheme, glue be easy with
It is bonded between jig, causes to draw glue, section out-of-flatness.
Invention content
The object of the present invention is to provide a kind of curved surface 3D touch screens or the AB type glue attaching process of display screen, solve curved surface
The problem of common box dam needs to cure and can not obtain the shape as glass cover-plate in the fitting of 3D glues.For this purpose, the present invention adopts
Use following technical scheme：
A kind of AB type glue attaching process of curved surface 3D touch screens or display screen, it is characterised in that：Using this glue of A during fitting
As box dam glue, using A, curing catalysts B glue is added in this glue to face glue, after curing before the adhesive curing of face and in cured condition, encloses
Dam glue is in gel state always, so that box dam glue is remained good thixotropy, face glue surrounding is made to obtain cutting for flat smooth
Face；The technique includes the following steps：
（1）Box dam glue is put on the glass cover-plate of curved surface 3D touch screens or display screen and forms glue frame, and the height of box dam glue is comprehensively high
In the display module lower surface of 3D touch screens or display screen；
（2）Face glue is put in glue frame；
（3）Display module is attached on the glue of face；
（4）Solidification；
（5）Wipe uncured box dam glue.
Further, the curing catalysts type selecting uses heat curing type, in order to obtain more operating times；It will show
Show that module is attached to face glue and goes forward, first opposite glue carries out precuring.
Further, face adhesiveness is adjusted between 1000 ~ 2000 mPa.s, and the glue viscosity the low more can be after the sizing of face glue
Better levelling effect is obtained, is gone forward due to being attached to face glue in display module, precuring can be carried out so that the gluing of face glue obtains
Good planarization after levelling can fully ensure that display module is pasted smooth.
Further, this adhesiveness of the A of box dam glue is adjusted to 5000 mPa.s ~ 10000mpa.s, is both convenient for dispensing operation, point
Box dam glue has good mouldability and thixotropy after glue.
Further, face glue glue and box dam glue glue use the glue of same glue system.
Due to technical solution using the present invention, the present invention uses this glue of A in using face glue AB glue as box dam glue, A
It is added without curing agent B glue in this glue, will not cure in high temperature and conventional environment, and thixotropy is strong, is with one with face glue
It is glue, will not reacts to each other, influence appearance and solidification effect；After the adhesive curing of face, box dam glue is still within for dispensing glue
Original state has good thixotropy and mouldability, and excessive glue, does not realize the fitting of complex-curved touch screen easily.

Fig. 2 is the schematic diagram of present invention demonstration fitting process.
Fig. 3 is bonding structure sectional view of the present invention.
Fig. 4 is the explosive view of citing product.
Specific implementation mode
It is below in conjunction with the accompanying drawings and specific real in order to make those skilled in the art more fully understand technical scheme of the present invention
Applying example, the present invention is described in further detail.
With reference to attached drawing.The glass cover-plate 1 of the 3D touch screens of the mobile terminal is the 3D structures of curved surface.
Using A, this glue is used as box dam glue during fitting, and using A, curing catalysts B glue is added in this glue to face glue, solid in face glue
Change before and in cured condition cure after, box dam glue always be in gel state, so that box dam glue is remained good thixotropy,
Present invention process method does not require box dam glue knead dough glue to keep high-precision flatness, so that the fitting of curved surface 3D touch screens is had good
Craftsmanship.
Wherein, B glue and this glue of A are combined as glue using the glue of same glue system.The range of choice packet of AB type glues
It includes：Two-component glue with heat cure or UV curing characteristics.But heat curing type glue craftsmanship meeting is used in the art
More preferably, the rational precuring effect of comparison can be obtained by the control of pre-cure time and temperature, is more advantageous to fitting；It is completely solid
Process conditions are easier to realize when change.Such as：The heat curing type two-component optical glue of silicon-type.
Fitting process is as follows：Box dam glue 2 is carried out on bend glass cover board 1 first, the height of box dam glue 2 only needs entirely
Face is higher than 4 lower surface of display module of 3D touch screens, this technique does not have particular/special requirement for the planarization of box dam glue；The
Two steps are clicked and entered the face glue glue amount that calculates using dispenser and must assure that level in carrying out face glue 3, dispensing platform in box dam glue 2
Degree, in case face glue is in uneven thickness；Third step is put into oven and carries out precuring, makes face glue precuring at the state of fruit juice gel, item
Part：40 DEG C ~ 50 DEG C of temperature, the purpose of time 20min ~ 30min, precuring make face gum forming, convenient for fitting operation, after precuring
Fitting need not be pasted in the environment of vacuum and, in an atmosphere carry out；4th step will be shown using jig or equipment
Module 4 is attached on face glue 3 and is bonded display module 4 with glass cover-plate；Product is put into high pressure deaeration machine by the 5th step to be taken off
Bubble, deaeration condition：Pressure 0.3Mpa, 10 minutes time；6th step is put into oven and is fully cured, solidification temperature 40 DEG C ~ 60
DEG C, 20 ~ 30min of time；7th step wipes uncured frame glue using non-dust cloth.Complete all process steps.
Due to the strong thixotropy of A this glue box dam glue, need not be glued by the shape of 3D touch screens when doing box dam, work
Skill is simple, does not need high precision apparatus, not excessive glue.
Above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art it is common
Technical staff, within the scope of the invention, the variation made change addition or replacement, should all belong to the scope of protection of the present invention.
