Embodiment
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
For output it is small, need to produce using the backlight of artificial pad pasting, in order to improve production efficiency, lifting fitting essence
Degree, the present invention provide a kind of method for die cutting of diaphragm integration, comprised the following steps：
A kind of method for die cutting of diaphragm integration, comprises the following steps：
S1：Distinguish composite protection film and bed die in the both sides of diffusion sheet；
S2：Referring to Fig. 3, first time cross cutting, waste discharge are carried out to diffusion sheet using the first cutting die self-insurance cuticula；Specifically, for the first time
During cross cutting, profile B is die cut out on diaphragm, profile C is die cut out on diffusion sheet, to the diaphragm outer frame outside profile B
Divide and carry out waste discharge with the diffusion sheet outer frame part outside profile C.
In the present invention, the knife edge of the first cutting die is made up of the outer layer knife edge and the internal layer knife edge, and the internal layer knife edge is located at described
There is gap in the outer layer knife edge, between the two, the shape that the internal layer knife edge used surrounds is identical with the shape of display panel visible area, institute
It is different with the depth of the internal layer knife edge to state the outer layer knife edge, when being die cut for the first time, the internal layer knife edge tripping protection film arrives at diffusion sheet,
The outer layer knife edge tripping protection film and diffusion sheet arrive at bed die；Positioning hole is got at the edge of bed die when being die cut for the first time, after
During continuous cross cutting, relative position that cutting die in positioning hole correspondence position use pilot pin to cover position to transmit during different cutting dies punchings；
S3：Referring to Fig. 4, the shading rubber belt with release PET film is compounded on diaphragm, using the second cutting die from release PET
Film carries out second to shading rubber belt set positioning hole and is die cut, and film cuts out profile A in release PET film and shading rubber belt, to profile
Release PET film and shading rubber belt and diaphragm inside A carry out waste discharge so that only retain outside profile A on diffusion sheet
Release PET film and shading rubber belt outer frame part；Shape inside the profile A is identical with display panel visible area shape；Its
In, the profile A interior shapes are identical with profile B interior shapes, smaller than inside profile C inside the profile B.
S4：Referring to Fig. 5, third time cross cutting is carried out to release PET film and shading rubber belt outer frame part using the 3rd cutting die, together
When thrust release PET film and shading rubber belt outer frame part, waste discharge, form integrated diaphragm.Specifically, when third time is die cut,
Release PET film and shading rubber belt outer frame part are die cut out profile D, and waste discharge is carried out to the outer frame part outside profile D.
Referring to Fig. 1-2, the integrated diaphragm that the present invention is formed includes the release PET for being sequentially overlapped setting from top to bottom
Film, shading rubber belt, diffusion sheet, counterdie, the periphery of the diffusion sheet are attached on the shading rubber belt, the shading rubber belt
At least a side extends beyond the respective side edge of the diffusion sheet, for being fixed with glue frame, the shape of the release PET film and screening
Optical cement band is consistent.
In the present invention, because bed die is compound with diffusion sheet, and diffusion sheet is inviscid, more usual shading bed die off-type force weight,
Therefore hold around the corner in profile waste discharge and cause shading deformation and burr.Therefore, the corner of the integrated diaphragm profile
Rounding is provided with, pullling between shading waste material and major ingredient can be alleviated after rounding, lifts waste discharge efficiency.In the present invention, rounding
Angular diameter is in more than 0.2mm.
Common cutting die knife depth 1mm-1.5mm, knife peak angle degree 30-50 degree, the present invention is improved to cutter die structure, referring to figure
6, in first cutting die, the second cutting die, the 3rd cutting die, the knife edge of tool bore is interior straight outer biassed fabric, avoids inside casing from being squeezed and leads
The problems such as causing deformation of products shading excessive glue.Preferably, the knife edge angle is in 25 degree of
Embodiment described above only expresses embodiments of the present invention, therefore its description is more specific and detailed, but can not be
And the limitation to the scope of the claims of the present invention is interpreted as, as long as the technical side obtained using the form of equivalent substitution or equivalent transformation
Case, it all should fall within the scope and spirit of the invention.
