Description
Technical field
The present invention relates to technology for manufacturing touch screen technical field, is pasted more particularly to a kind of modified touch-screen glass cover-plate
The tool of OCA glue.
Background technology
The structure of mobile phone liquid crystal screen curtain is divided into glass cover-plate, touch-screen, LCDs three parts.It is to need between per part
It is bonded, i.e., needs to be bonded between glass cover-plate and touch-screen, is also required to be bonded between LCDs and touch-screen.
Wherein, being bonded between glass cover-plate and touch-screen needs to use OCA glue to be bonded.
OCA (Optically Clear Adhesive) is a kind of spy for being used for cementing transparent optical element (such as camera lens)
Kind of adhesive, have water white transparency, light transmission rate more than 90%, cementing strength it is good, can solidify under room temperature or medium temperature, and
There is the features such as cure shrinkage is small.The two-sided double coated film with release liners is made in OCA glue, and the square as glass cover-plate is made
Shape, the specification of glass cover-plate is more somewhat larger than OCA film, during fitting, it is desirable to by OCA film plasters glass cover-plate centre,
The edge edge equidistant placement corresponding with OCA films of glass cover-plate after being bonded, as shown in figure 1, glass cover-plate B specification
More somewhat larger than OCA films A, during fitting, left and right margins a, upper bottom margin is b.In the prior art, pasted on glass cover-plate
The operation of OCA films is using having been manually done, and centering effect is poor, and efficiency is low.Also there is technical staff to devise some to be used to improve
The defects of being bonded the tool of quality and efficiency, but be inconvenient to use in the presence of some, for example, do not account for glass cover-plate and
The style characteristic of OCA films, lack the function of discharge air, when causing to place OCA films and glass cover-plate, produce in place unstable
The problem of.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of modified touch-screen glass cover-plate patch
The technical scheme of the tool of OCA glue.
The technical solution of the utility model includes：Upper mould, cushion, base；The upper mould is rectangular box, and its endoporus is
Rectangular step shape, including step, square frame side, at the middle part of two opposite side of square frame it has been provided with die cavity；The cushion is located at
Between upper mould and base；The base is the rectangular boss shape supporting with the upper mould, including boss, boss side surfaces, plays die cavity；
The base is coordinated with the upper mould by square frame side with boss side surfaces to be assembled integrally；Square frame between step and bottom surface
Side is provided with several steam vents, and the height of the base boss top surface is steam vent central horizontal line place plane
Interior, the compressible amount of the cushion is more than the distance between the base boss top surface and the upper die station terrace.
Further, the middle part played die cavity and be located at two long sides of the upper mould square frame, accordingly, the base boss
Play the middle part that die cavity is also provided in two long sides.
Structure and working principle of the present utility model is：The base is put on the table, the cushion is set with
Put in the corresponding position of the base, then the square frame side of the upper mould and the boss side surfaces of the base be assembled integrally,
The position of the base boss top surface the steam vent horizontal centre line institute planar；In use, first by a piece of OCA glue
It is placed on the base boss top surface, the release liners of the one side of piece OCA glue is thrown off using a die cavity, the glass cover-plate is placed on
On the step of the upper mould, then upper mould is pressed downward so that glass cover-plate is combined with the OCA stickers.
Compared with prior art, the beneficial effects of the utility model are：Due to the effect of steam vent, the OCA is being placed
During film and glass cover-plate and the upper mould fitting of pressure, without the obstruction of air drag so that fitting reliable in quality, steady
It is fixed, and improve operating efficiency.
