Description
Technical field
It the utility model is related to the technology for applying for touch-screen foam, and in particular to a kind of to be controlled for what foam bonded
Tool.
Background technology
It is each to have been widely used for our daily lifes as a kind of simple, easily human-computer interaction medium for touch-screen
A field, as smart mobile phone, intelligent watch, navigation system, digital camera, game station, display, electrical equipment control, medical treatment are set
It is standby etc..
Essentially all of touch-screen is required for being used cooperatively with liquid crystal module.Touch-screen has two kinds of sides of fitting with liquid crystal
Formula, one kind are frame patches, and one kind is to paste entirely.So-called frame patch exactly sticks a circle foam in the visible area surrounding of touch-screen, then uses
Foam is bonded with liquid crystal.This foam can play function that is dust-proof, and preventing falling (buffering).
Because the liquid crystal module of mobile phone, tablet develops to narrow frame, the design width of foam is got in complete machine space
Come narrower, the most narrow place of foam of many mobile phones only has the width of 0.7mm.If using yi word pattern or L-type foam with touch-screen
Hollow is spliced into during fitting, because foam is too elongated, there can be fitting and be not allowed, fitting is not straight, causes spliced foam to rise
Less than the effect of sealing and dustproof, and foam can be caused to leak out visible area, influence visual effect because off normal.For the ease of processing
Make, existing foam uses the design method of square shape.
Utility model content
To solve the above-mentioned problems, the application provides a kind of gauge bonded for foam, is being bonded to avoid foam
Occurs phenomena such as foam fitting is inaccurate, and fitting is not straight in journey, specific technical solution is as follows：
It is a kind of for foam bond gauge, it includes bottom plate, the bottom plate with a lower surface and with the lower surface phase
The upper surface of the back of the body, is provided with a rectangular ring groove on the upper surface, and the stomata is evenly arranged along rectangular ring groove；
The stomata through bottom plate is offered in the slot bottom of rectangular ring groove；
The gauge further includes exhaust part, which there is the pumping chamber of an above-mentioned stomata of connection and one to be used to connect pumping
The bleeding point of vacuum system.
Along being observed perpendicular to the upper surface of gauge, the inside edge of the rectangular ring groove and outer ledge are in
Rectangle.
Gauge in the utility model can use the material with certain rigidity and with stronger anti-corrosion ability to make, excellent
Choosing is made of materials such as bakelite or stainless steels.
When the utility model is used, foam bar is arranged in rectangular ring groove first, foam bar is set to be spliced into mouth
Font, is then evacuated with pumped vacuum systems through bleeding point, exhaust part is formed negative pressure state, under negative pressure, foam bar is whole
Body is to rectangular ring groove inner close fitting, so that foam bar is integrally more smooth, is not in the bad phenomenons such as fold, makes foam
Bar can be more entirely bonded on PET release films.
After the utility model gauge, due to the limitation of rectangular ring groove, when being pasted, foam is not in
Phenomena such as bending, and then make foam off normal, reduce the sealing and dustproof effect of foam.PET release films use poly terephthalic acid
Release film made by glycol ester.
Further, the depth of the rectangular ring groove is less than the height of the foam.Preferably, the rectangular ring is recessed
The height 0.15-0.25mm of the depth of groove≤foam.As a result of vacuum suction, the bottom surface of foam can be made to support completely
Lean against the bottom surface of rectangular ring groove, make rectangular ring groove depth be less than the foam height when, can ensure PET from
Type film carries out be bonded with foam, and according to the difference of PET release film weight and the difference of foam elasticity, the height of foam is set
It between 0.15-0.25mm, can effectively ensure PET release films on foam is placed on, be contradicted in PET release films to gauge
Before can complete it is bonding with foam, even if PET release films contradict gauge upper surface, still be able to ensure PET release films with
Foam forms stable bonding.
Specifically, the exhaust part includes a tablet, which has a mounting surface, the installation downwards concave shape into one
Concave part, the tablet are fixed on the lower surface of the bottom plate through mounting surface, and the concave part forms the pumping chamber, the pumping
Gas port is formed on the side perpendicular with the mounting surface of tablet.Above-mentioned design can be that the utility model has the advantages of simple structure and change, and carry
High processing efficiency.
Specifically, a diameter of 0.04-0.12mm of the stomata.Can be to avoid part under negative pressure using minor diameter stomata
Foam is inhaled into stomata, influences the integrality of foam.
Further, positioning column is provided with the outside of rectangular ring groove, the positioning column is arranged on the upper surface of bottom plate
On, and extend along the direction of the upper surface away from bottom plate, the positioning column is perpendicular to the upper surface of bottom plate.Preferably, in rectangle
The opposite both sides of annular recess respectively set a positioning column, and the positioning column is cylindrical.
The positioning column is used to fix PET release films, is provided with and special determines corresponding to above-mentioned positioning column on PET release films
PET release films, under the limitation of the positioning column, can quickly be bonded on foam by position hole, and accurate positioning.Avoid behaviour
When making, during using visually observing positioning, being easy to deviations occur, foam is deviateed setting position.Especially in rectangular ring
When the opposite both sides of groove respectively set a positioning column, accurately PET release films can be bonded together with foam.By positioning column
After being arranged to cylindric, the processing to positioning column is not only convenient to, but also facilitates PET release films relative to foam sticking tool
Rotated, to be finely adjusted.
When the foam stickup of touch-screen is carried out using the above-mentioned gauge bonded for foam, using following steps：
(1) foam is arranged to two L-shaped foam bars；
(2) it is gauge is horizontal positioned, make its upper surface upward, two foam bars are then filled in rectangular ring groove
It is interior, and the upper table of foam bar is exceeded the upper surface of gauge upwardly；
(3) vacuum system is started, it is in negative pressure state to make pumping pumping chamber, and foam bar is flat under the action of negative pressure
State；
(4) PET release films are placed on gauge, and foam bar is bonded on PET release films；
(5) the PET release films for being bonded with foam bar are departed from into gauge.
In this method of attaching, foam is arranged to L-shaped foam bar first, the foam bar then is filled in level puts
In the rectangular ring groove for the gauge put, and carrying out pumping enables the bottom surface of foam bar to be entirely resisted against, while makes foam
The upper surface of bar also reaches formation state, then PET release films are placed on gauge, foam bar is bonded in PET release films
Together, finally PET release films are removed from gauge, process is arrived into lower.Under the limitation of rectangular ring groove, foam bar is not
Displacement can be produced, by the bonding process of PET release films and foam bar, even if due to producing a little offset, is being corrected
During, due to the limitation of rectangular ring groove, foam bar will not produce movement, remain at original position, make foam bar
It can be bonded on the setting position of PET release films.
Using caused negative pressure is vacuumized, foam bar can be made to form the state of smooth laying, avoided using by hand
During operation, foam bar may be made the generation of buckling phenomena occur.
