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.
Backlight module is one of important composition component of liquid crystal display, since liquid crystal itself does not shine, backlight mould
The illumination effect of group directly influences the display effect of liquid crystal display.Existing backlight module has generally comprised backboard, reflection
Piece, backlight and light guide plate etc., in backlight module, reflector plate is normally at the bottom surface of light guide plate, for by the bottom of light guide plate
The light that face leaks out is reflected back in light guide plate, to increase the service efficiency of light.
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 reflectance coating also need to punch, for this reason, it may be necessary to which the punching cutting process to reflectance coating 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 reflectance coating 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 reflectance coating, which is characterized in that include the following steps,
S10 is die cut on the reflectance coating and rushes aperture and shape；
S20 is arranged at aperture and the reflectance coating waste material of side edge；
S30 sticks protective film.
In a preferred embodiment, in step slo, it is punched since the non-reflective surface side of the reflectance coating.
In a preferred embodiment, it in step S20, is removed by having sticking OPP adhesive tape bonding on one side
At aperture and the reflectance coating waste material of side edge.
In a preferred embodiment, the OPP adhesive tape passes through adjacent two rubber rollers and the reflection film compacting
Fitting, to be bonded waste material waste discharge.
In a preferred embodiment, in step slo, the punching of reflectance coating 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 reflectance coating by cross cutting one-step shaping, and will be at aperture and frame
The reflectance coating waste material at place disposably excludes, and the whole concise in technology that cuts is efficient, can fast implement with the anti-of front camera hole
Penetrate the processing of 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 is referred to as " fixation ", " connection " 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 as used herein " and/or " it include 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 reflectance coating of one embodiment of the invention, in the process
In, include following steps: S00, reflection film raw material being posted on carrier film；S10, cross cutting rushes aperture on the reflectance coating
And shape；S20, row aperture at and side edge reflectance coating waste material；S30, protective film is sticked；S40, winding cut after the completion of it is anti-
Penetrate film.
Referring to Fig. 2, Fig. 2 is the cross-sectional view before the punching of the reflectance coating of one embodiment of the invention.In the present embodiment, make
Reflectance coating for raw material includes lower protective film 2 and reflection membrane body 1, wherein the reflecting surface of reflection membrane body 1 is towards lower protection
Film 2.
