Abstract
The invention discloses a production process for a protective film. The production process comprises the following steps of overlaying a PET protective film, a first PE protective film and a second protective film together successively to form a raw material; and performing one-time punching on the raw material, so that the PET protective film and the first PE protective film are broken at the outline of an outer frame of the protective film; simultaneously, the PET protective film is broken at the outline of an inner frame of the protective film; and that the PET protective films at the outlines of both the inner frame and the outer frame of the protective film are adhered on the first PE protective film at the outline of the outer frame of the protective film. The production process for the protective film has low cost, economic working procedures and low defective fraction.
Description
Technical field
The present invention relates to touch screen protective film field, particularly relate to a kind of diaphragm production technology.
Background technology
Traditional touch-screen reverse side diaphragm generally comprises two-layer PET diaphragm, and its production technology is numerous and diverse, and cost is high, the undesirable condition such as dirty, the dust fall of the as easy as rolling off a log appearance in diaphragm edge during the diaphragm applying touch-screen produced.
Summary of the invention
Based on this, be necessary for the prior art defective, a kind of with low cost, operation saving, diaphragm production technology that fraction defective is low are provided.
Its technical scheme is as follows.
A kind of diaphragm production technology may further comprise the steps:
With PET diaphragm, a PE diaphragm and the 2nd PE diaphragm formation raw material that overlap successively;
Raw material are carried out disposable punching press; PET diaphragm and a PE diaphragm disconnect at diaphragm housing profile place; simultaneously, the PET diaphragm disconnects at diaphragm inside casing profile place, and the PET diaphragm of diaphragm internal and external frames profile all sticks on the PE diaphragm of diaphragm housing profile.
In the technical program; when raw material are carried out disposable punching press; the mould of selecting has dark blade and shallow blade, and dark blade disconnects PET diaphragm and a PE diaphragm at diaphragm housing profile place, and shallow blade disconnects the PET diaphragm at diaphragm inside casing profile place.
The present invention also provides a kind of diaphragm; comprise PET protective film and a PE protective film; described PET protective film comprises diaphragm inside casing layer and diaphragm housing layer, and described diaphragm inside casing layer is connected with described diaphragm housing layer by a described PE protective film.
The present invention also provides a kind of touch-screen assembly technology, may further comprise the steps:
Tear the PET diaphragm of diaphragm housing profile, touch-screen and casing are fitted, tear the PET diaphragm of diaphragm inside casing profile, the applying display screen.
The below describes advantage or the principle of technical solution of the present invention.
Technical solution of the present invention only need provide one deck PET diaphragm, and the PET diaphragm only needs blanking, fits once in the diaphragm production technology, is not prone to the unfavorable conditions such as dirty dirty, dust fall, and with low cost, operation saving, fraction defective are low.
Description of drawings
Fig. 1 is the described diaphragm production technology of embodiment of the invention diaphragm structural representation;
Description of reference numerals:
10, PET diaphragm, the 20, the one PE diaphragm, the 30, the 2nd PE diaphragm, 40, diaphragm housing layer, 50, diaphragm inside casing layer.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is elaborated.
Embodiment of the invention diaphragm production technology may further comprise the steps:
With PET diaphragm 10, a PE diaphragm 20 and the 2nd PE diaphragm 30 formation raw material that overlap successively;
Raw material are carried out disposable punching press, PET diaphragm 10 and a PE diaphragm 20 disconnect at diaphragm housing profile place, simultaneously, PE diaphragm 10 disconnects at diaphragm inside casing profile place, and the PET diaphragm 10 of diaphragm internal and external frames profile all sticks on the PE diaphragm 20 of diaphragm housing profile;
Divest PET diaphragm 10 and a PE diaphragm 20 waste materials, diaphragm is peeled from the 2nd PE diaphragm 30.
The mould release membrance that present embodiment diaphragm diaphragm that production technology is produced is torn PET diaphragm 10 touch-screen of can fitting.
In present embodiment diaphragm production technology; when raw material are carried out disposable punching press; the mould of selecting has dark blade and shallow blade; dark blade disconnects PET diaphragm 10 and a PE diaphragm 20 at diaphragm housing profile place, shallow blade disconnects PET diaphragm 10 at diaphragm inside casing profile place.
The diaphragm that embodiment of the invention diaphragm production technology is produced; comprise 20 layers of 10 layers of PET diaphragms and PE diaphragms; 10 layers of PET diaphragms comprise diaphragm inside casing layer 50 and diaphragm housing layer 40, and diaphragm inside casing layer 50 is connected with diaphragm housing layer 40 by a PE protective film 20.
The touch-screen assembly technology of the diaphragm that application embodiment of the invention diaphragm production technology is produced; may further comprise the steps: the PET diaphragm that tears diaphragm housing profile; touch-screen and casing are fitted, tear the PET diaphragm of diaphragm inside casing profile, the applying display screen.
The below describes advantage or the principle of the embodiment of the invention.
The embodiment of the invention only need provide one deck PET diaphragm, and the PET diaphragm only needs blanking, fits once in the diaphragm production technology, is not prone to the unfavorable conditions such as dirty dirty, dust fall, and with low cost, operation saving, fraction defective are low.
Above embodiment is described only to have expressed several embodiment of the present invention, and it describes comparatively concrete and in detail, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
