Abstract
The invention discloses a CTP full fitting technology which comprises the following steps: rubberizing: putting a touch screen on a soft-hard equipment platform, fixing the touch screen, using a suction nozzle platform to absorb OCA glue, and fitting the OCA glue on the touch screen; heating: heating the touch screen fitting with the OCA glue, wherein the heating temperature is 35-45 DEG C and the heating time is 20-25 s; fitting: putting protective glass on a hard-hard equipment platform, fixing the protective glass, and fitting the touch screen fitting with the OCA glue with the protective glass. With adoption of the CTP full fitting technology, after hard-hard fitting, the phenomenon that the OCA glue overflows or is off normal can be avoided, the reworking and scrapping rate of the OCA glue is directly and effectively decreased, and the production efficiency is improved; in addition, the equipment platforms do not need to be modified, and the idler wheel stroke is also sufficient.
Description
Technical field
The present invention relates to touch-screen manufacture field, more particularly relate to the full attaching process of a kind of CTP.
Background technology
In CTP(multipoint capacitive touch screen) entirely fit in production run; conventional attaching process technology is simulation LCM(liquid crystal display module) full laminating type produce; invest on cover glass by OCA sticker, then the cover glass and liquid crystal display module that are stained with OCA glue are fitted.Because OCA is attached on cover glass, cover glass does not have gauge point, attaches and occurs deviation, finally hard to occurring after hard laminating that OCA glue overflows glue or OCA glue off normal phenomenon, cannot meet the requirement of accurately placing.
The full laminating type of CTP conventional in prior art first invests gluing for OCA on cover glass on hard platform soft, and then firmly touch-screen and cover glass adhered to each other on hard platform.But because cover glass is than the monolateral large 10-15mm of OCA glue, adhere to precision wayward, and hard to hard laminating after there will be OCA and to overflow the phenomenon of glue or OCA off normal.The size of cover glass is greater than the hard area to computer hardware platform in addition, needs amendment equipment roller stroke, and amendment carrying platform.
Summary of the invention
For solving the problem of above-mentioned prior art, the invention provides the full attaching process of a kind of CTP, this technique makes, in the hard phenomenon that the rear OCA glue of hard laminating be there will not be to excessive glue or off normal, directly effectively to reduce doing over again of OCA and scrap, improving production efficiency.
Technical scheme of the present invention is: the full attaching process of a kind of CTP, comprises the following steps:
Rubberizing: get touch-screen and be positioned over soft to fixing on hard platform, uses nozzle platform to draw OCA glue and by this OCA glue laminating on the touchscreen;
Heating: heat the touch-screen posting OCA glue, heating-up temperature is 35 ~ 45 DEG C, and the heat time is 20 ~ 25s;
Laminating: fetch protection glass is positioned over firmly to also fixing on hard platform, the touch-screen and cover glass that post OCA glue is fit together.
Described touch-screen is positioned over softly goes forward to computer hardware platform, cleans described touch-screen.
Described cover glass is positioned over goes forward to computer hardware platform firmly, cleans described cover glass.
Nozzle platform is first carried out optical fiber to bit correction to OCA, is made the edge line of OCA glue parallel with the edge line of touch-screen after drawing OCA glue, then by OCA glue laminating on the touchscreen.
In a preferred embodiment, described heating-up temperature is 40 DEG C, and the described heat time is 20s.
The full attaching process of CTP that the present invention proposes is by directly adhering to OCA glue on the touchscreen, because touch-screen is than the monolateral large 0.5mm of OCA glue, thus make in the hard phenomenon that the rear OCA glue of hard laminating be there will not be to excessive glue or off normal, directly effective doing over again of OCA of minimizing is scrapped, improving production efficiency; And equipment platform is without the need to amendment, roller stroke is also enough.

Fig. 2 is the product schematic diagram adopting the full attaching process of CTP of the present invention;
Fig. 3 is the cut-open view in Fig. 2.
Embodiment
As shown in Figure 1 to Figure 3, the full attaching process of CTP that the present invention proposes comprises the following steps:
S1, rubberizing: get touch-screen 1 and be positioned over soft to also fixing on hard platform, use nozzle platform to draw OCA glue 2 and also this OCA glue 2 is fitted on touch-screen 1;
S2, heating: the touch-screen 1 posting OCA glue 2 is heated, heating-up temperature is 35 ~ 45 DEG C, and the heat time is 20 ~ 25s;
S3, laminating: fetch protection glass 3 is positioned over firmly to also fixing on hard platform, is fit together by the touch-screen 1 posting OCA glue 2 with cover glass 3.
Step cleaning was also comprised before step S1; Touch-screen 1 is positioned over softly goes forward to hard platform, cleans touch-screen 1; Cover glass 3 is positioned over goes forward to computer hardware platform firmly, cleans cover glass 3, and cleaning touch-screen 1 and cover glass 3 can reduce error when fitting.
Nozzle platform is first carried out optical fiber to bit correction to OCA glue 2, is made the edge line of OCA glue 2 parallel with the edge line of touch-screen 1, then be fitted on touch-screen 1 by OCA glue 2 after drawing OCA glue.
In the present embodiment, optical fiber is carry out accurately bit correction OCA glue 2 to bit correction, optical fiber is the edge (90 ° of right angles) directly correcting OCA glue 2 and touch-screen 1 to bit correction, namely make the edge line of OCA glue 2 parallel with the edge line of touch-screen 1, which reduce the relative position size corrected when equipment attaches.
In the present embodiment, heating-up temperature is 40 DEG C, and the heat time is 20s.
After each limit in the present invention on OCA glue 2 is all parallel with each limit on touch-screen 1, distance between the limit that OCA glue 2 is corresponding with on touch-screen 1 is 0.5mm, because size disparity is between the two very little, deviation is there will not be when being attached on touch-screen 1 by OCA glue 2, therefore OCA glue 2 there will not be excessive glue or off normal, OCA glue 2 can be placed accurately.
Above specific embodiment is only in order to illustrate design of the present invention, and those of ordinary skill in the art can make various deformation and change under design of the present invention, and these distortion and change include within protection scope of the present invention.
