Description
Technical field
The present invention relates to touch screens and display screen glue attaching process, are greater than 10 inches in particular with screen size
Or the applying method of Curved screen.
Background technique
Touch screen be it is a kind of simply, conveniently, natural human-computer interaction device, be widely used in mobile phone, wearing, work
The every field such as control, vehicle-mounted.In industry control and automotive field since use environment is severe, it is necessary to realize touching using glue series glue
Touch the fitting of screen and display screen.Fitting in the coating technique of existing touch screen and display screen, for large-size screen monitors and abnormal curved surface
Dedicated equipment is needed, process costs are high, and technology difficulty is big, and yield is low.Cause glue attaching process that can not be widely applied.
Summary of the invention
The object of the present invention is to provide the glue attaching process of a kind of touch screen of simple process and display screen.For this purpose, this
Invention uses following technical scheme:
A kind of touch screen and display screen glue attaching process, it is characterised in that: by the first pre- fitting of touch screen and display screen, touch screen
There are the uniform gaps with boundary and injecting glue entrance between display screen, then fill the water glue in the gap, then solidify
Glue bonds touch screen and display screen；The boundary has gas vent.
On the basis of using above technical scheme, the present invention also be can be used or be combined using technical side further below
Case:
The glue is heat cure glue, described to be cured as being heating and curing.
Thickness needed for height and the glue fitting in the gap is contour.
The gap and boundary are formed by foam tape, first post foam rubber in display screen front, are formed and are limited gap height
Then touch screen is pasted on the support of degree and boundary on it again, the foam tape has the hole for injecting glue and gas vent.
Foam tape thickness is equal to glue required thickness.
After display screen front fitting foam tape, the release paper on its surface is torn, then touch screen ruler as required
It is very little to be attached in foam tape completely.
The injecting glue is exactly a hole for injecting glue to be reserved when pasting foam tape, then glue is injected injecting glue by syringe needle
In hole, until filling.
The present invention is an attaching process for completely new touch screen and display screen, is especially suitable for the touching to large screen or Curved screen
The fitting for touching screen and display screen is able to solve the problem of these screens are easy blistering using commonsense method patch, it is an advantage of the invention that
It is high to be bonded quality, it is not easy to foaming, should not dedicated glue sizing equipment, required equipment cost is low, it is only necessary to which mixed gluing equipment is being infused
It can arrange to check fitting quality before glue, yield is higher with respect to other techniques.
Detailed description of the invention

Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, the present invention is made below further
Detailed description.
The present invention has excellent suitability for the fitting of large-size screen monitors and abnormal curved surface, for large-size screen monitors display screen fitting not
Dedicated equipment is needed, the present embodiment is by taking the screen of 10 inch dimensions as an example.
Glue viscosity used in being bonded is at room temperature preferably not more than 2000 mPa.s, generally 1000 ~ 2000
MPa.s, to guarantee that the lower good mobility, the viscosity of glue the better；Glue selects the glue of heat cure series, such as silica gel
It is two-component heat cure glue.
There are the uniform gap 5 with boundary and injecting glue entrance between touch screen 3 and display screen 1, the gap 5 is preferably not
It is less than 0.5mm；The boundary has gas vent 6.The gap and boundary are formed by foam tape, first in the positive face paste of display screen
Good foam rubber, forms the support for limiting clearance height and then touch screen is pasted on boundary on it again, and the foam tape has note
Glue hole 4 and gas vent 6.
Fitting process is as follows: foam tape 2 is pasted first on the positive face of display screen 1, the thickness of foam tape 2 need to be equal
The position of glue thickness after solidification, foam tape patch needs to avoid touch screen visible area, the inside edge shape of foam tape
At the boundary line of glue, there are gum-injecting ports 4, gas vent 6 for foam tape 2；Second step is by touch screen 3 and posts the aobvious of foam tape
Display screen carries out contraposition fitting, can be aligned using jig shape, can also use equipment automatic decimal alignment system；Touch screen after fitting
The gap 5 that with display screen there is the thickness of celloidin band 2 to determine.
Before carrying out third step, visual visual examination is carried out, excludes appearance caused by the dust in fitting gap enters
It is bad.
In the space between touch screen and display screen that third step posts glue injection, until filling；It finally will note
The touch screen of full water glue is put into heating furnace and is fully cured, condition: temperature 45 C ~ 65 DEG C, time 20min ~ 30min, solidification
Excessive glue is removed after the completion.
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, all should belong to protection scope of the present invention.
