Description
Technical field
The present invention relates to optical element processing technique field more particularly to a kind of punching cutting process of bright enhancement film.
Background technique
Die-cutting machine (Die Cutting Machine), is called hydraulic cutting presser, guillotine and numerical control stamping machine, is mainly used for corresponding
Some nonmetallic materials, adhesive sticker, EVA, double-sided adhesive, electronics and mobile phone rubber mat etc. cross cutting (complete disconnected, half disconnected), impression, scald
Gold, fitting and automatic waste discharge, die-cutting machine pass through coining using steel knife, hardware dies and steel wire (or steel engraving at template)
Version applies certain pressure, and printing or cardboard are rolled and are cut into certain shapes.
Bright enhancement film is also referred to as brightness enhancement film, condensing film or BEF, is widely used in opto-electronics, is issued for converging light source
Light.Bright enhancement film is mounted on the light-emitting surface of backlight, the light that backlight issues will be assembled towards user direction, thus can mention
The positive emitting brightness of high backlight, also, unemployed light outside visual angle are recycled according to the reflection effect again of light,
And assembled with optimal angle towards user.Bright enhancement film is usually to be arranged to make up by many a prism bars according to a direction
, form a prism array.
In order to realize the comprehensive screenization of display screen for the mobile phone for having front camera, (95% or more screen occupies
Rate), it is required that the backlight module aperture as light source, to place front camera, wherein the important composition as backlight module
One of bright enhancement film also need to punch, for this reason, it may be necessary to which the punching cutting process to bright enhancement film carries out design of making rational planning for.
Summary of the invention
The technical problems to be solved by the invention are how to realize quickly having for the bright enhancement film with front camera hole
Effect processing.
The technical proposal adopted by the invention to solve the above technical problems is that:
A kind of punching cutting process of bright enhancement film, comprising the following steps: S10, on the bright enhancement film cross cutting rush aperture and
Shape；S20, row aperture at and side edge bright enhancement film waste material；S30, patch third protective film.
In a preferred embodiment, in step slo, it is punched since the prism surface side of the bright enhancement film.
In a preferred embodiment, it in step S20, is removed by having sticking OPP adhesive tape bonding on one side
At aperture and the bright enhancement film waste material of side edge.
In a preferred embodiment, the OPP adhesive tape passes through adjacent two rubber rollers and the film compacting that adds lustre to
Fitting, to be bonded waste material waste discharge.
In a preferred embodiment, in step slo, the punching of bright enhancement film is realized by single seat die-cutting machine.
The beneficial effects of the present invention are:
The present invention directly cuts out the shape of aperture and bright enhancement film by cross cutting one-step shaping, and will be at aperture and frame
The bright enhancement film waste material at place disposably excludes, and the whole concise in technology that cuts is efficient, can fast implement the increasing with front camera hole
The processing of light film.

Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu, complete description, to be completely understood by the purpose of the present invention, scheme and effect.It should be noted that the case where not conflicting
Under, the features in the embodiments and the embodiments of the present application can be combined with each other.
It should be noted that unless otherwise specified, when a certain feature referred to as " fixation ", " connection " are in another feature,
It can directly fix, be connected to another feature, and can also fix, be connected to another feature indirectly.In addition, this
The descriptions such as upper and lower, left and right used in invention are only the mutual alignment pass relative to each component part of the present invention in attached drawing
For system.
In addition, unless otherwise defined, the technology of all technical and scientific terms used herein and the art
The normally understood meaning of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without
It is to limit the present invention.Term " and or " used herein includes the arbitrary of one or more relevant listed items
Combination.
Referring to Fig.1, Fig. 1 is the flow chart of the punching cutting process of the bright enhancement film of one embodiment of the invention, in the process
In, include following steps: S00, the film raw material that will add lustre to are posted on carrier film；S10, cross cutting rushes aperture on the bright enhancement film
And shape；S20, row aperture at and side edge bright enhancement film waste material；S30, patch third protective film；After the completion of S40, winding are cut
Bright enhancement film.
Referring to Fig. 2, Fig. 2 is the cross-sectional view before the punching of the bright enhancement film of one embodiment of the invention.In the present embodiment, make
Bright enhancement film for raw material includes the first protective film 1, add lustre to membrane body 2 and the second protective film 3, wherein the rib for the membrane body 2 that adds lustre to
