Abstract
The invention discloses an improved optical adhesive bonding process. In a bonding process of a touch cover plate and a touch sensor, a non-bonding surface of the touch cover plate and a non-bonding surface of the touch sensor are protected by protective films, so as to prevent scratch and secondary pollution of the product, as well as reduce adhesive overflow wiping action in the sequent bonding process. Bonding surfaces of the touch cover plate and the touch sensor are cleaned by a roller rather than a non-dust cloth to improve the cleaning efficiency, so as to enhance the productivity and yield, and optimize the process.
Description
Technical field
The present invention relates to technology for attaching capacitive touch screens, particularly a kind of improved optical cement attaching process.
Background technology
During the operation of liquid crystal panel industry production, cover lens (touch cover plate) is two kinds of branches with sensor (touch sensor) attaching process: the firstth, and OCA (solid state optics glue) fits, and the secondth, the liquid optical cement of LOCA is fitted.Use the easily excessive glue in LOCA liquid state optical cement applying no frame adhesive process applying back, need clean the glue part of overflowing after having fitted, and this applying process of completion need and then be accomplished and fit in the industry on abutted equipment list article cover lens, sensor clean.Have excessive glue after the applying, and the operation of back need be fallen excessive glue clearly because the liquid optical cement of LOCA is liquid glue, be easy to make dirty product and working environment, cause need be again and again cleaning.At present; The liquid optical cement attaching process of LOCA; Applying is gone to toward all being that cover lens, sensor clean are exposed outside, and the easy so excessive glue of secondary pollution and applying back that causes remains in lens, sensor surface, causes more manpower to clean cull.
Summary of the invention
Technical problem to be solved by this invention is: mainly solve and reduce the production capacity and the yield of fitting section cleaning manpower, man-hour and promoting the back segment inspection process.
To above-mentioned purpose, the present invention takes following technical scheme: a kind of improved optical cement attaching process is characterized in that its step is following:
1) carries out Incoming Quality Control to touching cover plate and touch sensor raw material;
2) carry out the diaphragm attaching to touching cover plate, and touch sensor binding face stripping glue is removed;
3) clean binding face with roller;
4) carry out the board applying to touching cover plate and touch sensor;
5) carry out the appearance test first time;
6) carry out pressure debubble;
7) cleaning cull and excessive glue;
8) final curing;
9) carry out the appearance test second time;
10 through the qualified products entering back operation after pasting.
Said roller is the silica gel roller.
Advantage of the present invention is that non-binding face of lens and the non-binding face of sensor all have diaphragm protection, can prevent the product scratch, also can prevent the product secondary pollution; The excessive rubber erasers that can reduce the back bonding process is again wiped away and is waited action, and uses the roller cleaning at cleaning lens, sensor binding face, does not need improve cleaning efficiency, thereby lifting production capacity and yield to make also technological process optimize more with the non-dust cloth cleaning.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further, referring to Fig. 1, a kind of improved optical cement attaching process is characterized in that its detailed step is following:
1) carries out Incoming Quality Control 101 to touching cover plate and touch sensor raw material: to the lens inspection of raw and process materials: be mainly and tear supplied materials diaphragm (process control materials) and test; It is for the defective of clearer check product such as printing ink aberration, material damage, scratch, point, impurity, bad item such as dirty that inspection process needs operation under illumination 800～1200lux (luminous intensity unit) environment, the purpose of tearing the supplied materials film.To the sensor inspection of raw and process materials: the same lens of environmental test, the project of check is: the angle collapses, sliver, scratch, white point, dirty etc.
2) carry out diaphragm and attach 102 touching cover plate, and to the purpose that touch sensor binding face stripping glue removes the 103:lens pasting protective film be: the convenient back of fitting the residual of glue of overflowing caused the product surface dirt and the waste of manpower wiping.The requirement of lens pasting protective film is:
A, diaphragm material need PET (high temperature resistance polyester film) material, and this material is hard and thinly be convenient to the Manufacturing Worker and use tool to attach, if do not reach its effect with the words of other softwood matter.
It is 1:1 that b, diaphragm require consistent with the lens size.Sensor binding face peelable glue removes purpose and is: the efficient of fitting for promoting, if not binding face also tears, cause dirty easily and scratch, also can let the applying board cause the material situation that stagnates, so only need tear binding face peelable glue protective layer.
3) with roller cleaning binding face 104: this roller material is full-bodied silica gel roller, and the roller size need be slightly larger than the product size size.Need to guarantee the cleanliness factor of roller synchronously.Prevent the product secondary pollution.
4) carry out board applying 105 to touching cover plate and touch sensor: applying is that board is accomplished automatically; Principle is that lens is positioned on the lower platform of machine; Sensor is positioned on the upper mounting plate of machine; And on sensor, put LOCA glue, overturn synchronously upper mounting plate and lower platform carry out pressing, let LOCA glued joint when touching the lens face and spread.
5) carry out appearance test 106 for the first time: the environment of appearance test is with above-mentioned environment, check be whether the liquid optical cement of LOCA of the product after check is fitted has diffusion at present.And verification of synchronization bubble, soft flocks etc. are bad, need improve processing if having then.
6) carry out pressure debubble 107: finding the concentrated pressure debubble processing of taking away of alveolate need to last inspection process, promptly is non-defective unit after the deaeration.
7) cleaning cull and excessive glue 108: the liquid optical cement of LOCA is the outside diffusion type of nature in the applying process; And this technology is no frame solation journey; So the liquid optical cement of inevitable LOCA overflows product edge, so need this part cull, the glue that overflows are carried out clean.Cleaning mode is that non-dust cloth is stained with solvent and is cleaned.Efficient is fast like this.
8) finally solidify 109: this technological process is liquid glue operation, so need solid-state being solidified into of liquid state.Solidification process is to put into UV stove (ultraviolet ray irradiation) to product, and UV light and glue material can be reacted into solid-state like this.
9) carry out appearance test 110 for the second time: this step is a kind of control test to the applying process, so that guarantee the yield of back operation.Examination requirements is to test according to the inspection specification that the client provides.
10) get into back operation 111 through the qualified products after pasting.
The present invention has increased the diaphragm operation of fitting, and reduces secondary pollution, and cleaning mode also changes to silica gel roller cleaning, thereby promotes production capacity and yield, and technological process is optimized more.
