Abstract
A kind of OCA optical cements, including the light film (1), OCA optical cements ontology (2) and weight film (3) being bonded successively, the light film (1) includes glass gluing portion (11) and face-piece sticking part (12), the face-piece sticking part (12) is arranged around the glass gluing (11) portion, the OCA optical cements are rectangular and are adapted with panel size to be fit that one end of the OCA optical cements offers groove body (4) compatible with the hole on panel to be fit.The beneficial effects of the utility model are：It eliminates and wants in addition process for dispensing glue in installation, improve production efficiency, solve the problems, such as attaching the excessive glue occurred in the process or bubble, improve the quality of production.
Description
Technical field
The utility model is related to optical cement technical field, more particularly to a kind of OCA optical cements.
Background technology
OCA is the extraordinary adhesive for cementing transparent optical element (such as camera lens/liquid crystal display).Require nothing
Color is transparent, light transmission rate is good in 90% or more, cementing strength, can cure under UV illumination, and have the features such as cure shrinkage is small.
OCA optical cements are one of the raw material of important touch screen, are that optics acrylic glue is made no base material, then in upper and lower bottom,
It is respectively bonded one layer of release film again, is a kind of two-sided fitting adhesive tape of no basis material.
The optical cement area ratio LCD shapes that full jointing product fitting uses at present are small, and optical cement area is less than normal to be susceptible to
It is bad to be bonded bubble etc..If LCD shapes are smaller than optical cement shape, it will appear the problem of optical cement puts up module.Therefore, for
Module is just pasted in being typically of size of for OCA optical cements, in next technique, dispensing again is still needed to carry out mobile phone
Assembling, influences speed of production.
Invention content
The purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of reasonable design, solves in assembling procedure
Dispensing and overflow adhesive and OCA optical cements the problems such as bubble again.
The technical scheme in the invention for solving the above technical problem is：A kind of OCA optical cements, including be bonded successively
Light film, OCA optical cements ontology and weight film, the light film include glass gluing portion and face-piece sticking part, the face-piece sticking part around
The glass gluing portion setting, the OCA optical cements are rectangular and are adapted with panel size to be fit, the OCA optical cements
One end offer groove body compatible with the hole on panel to be fit.
In some embodiments, the edge of the face-piece sticking part, which is provided with, tears hand, is provided in the glass gluing portion
Easily tear patch.
In some embodiments, the area equation of the heavy film, OCA optical cements ontology and light film.
In some embodiments, the thickness of the light film is less than the thickness of the heavy film.
The beneficial effects of the utility model are：The utility model is enable to paste entire surface the rational design of light film
Plate eliminates and wants in addition process for dispensing glue in installation, improve production efficiency, solves the excessive glue occurred in the process in attaching
Or the problem of bubble, improve the quality of production.

Specific implementation mode
The utility model is done with reference to the accompanying drawings and examples and is furtherly illustrated.
In Fig. 1 to Fig. 4, a kind of OCA optical cements, including the light film 1, OCA optical cements ontology 2 and the weight film 3 that are bonded successively,
Light film 1 includes glass gluing portion 11 and face-piece sticking part 12, and face-piece sticking part 12 is around 11 settings of glass gluing, OCA optical cements
It is rectangular and be adapted with panel size to be fit, one end of OCA optical cements is offered to be adapted with the hole on panel to be fit
Groove body 4.
The edge of face-piece sticking part 12, which is provided with, tears hand 14, is provided in glass gluing portion 11 and easily tears patch 13, convenient to make
Used time tears light film 1.
The area equation of weight film 3, OCA optical cements ontology 2 and light film 1.
The application method of the utility model is：It tears weight film 3 off, OCA optical cements ontology 2 and display screen is attached, then, torn
The glass gluing portion 11 of light film 1 is opened, protective glass is attached, face-piece sticking part 12 is finally torn off, face-piece is attached.
The utility model has the advantage of：The utility model is enable to paste entire panel the rational design of light film,
Eliminate in installation will other process for dispensing glue, improve production efficiency, solve attach the excessive glue that occurs in the process or
The problem of bubble, improves the quality of production.
Only the most preferred embodiment of the utility model is described above, but is not to be construed as the limit to claim
System.The utility model is not only limited to above example, and concrete structure is allowed to vary.It is all in the utility model independent right
It is required that protection domain in made by various change in scope of protection of the utility model.
