Abstract
The utility model discloses a kind of integrated diaphragm, shading counterdie, PET film, shading rubber belt, diffusion sheet, diffusion counterdie including being sequentially overlapped setting from top to bottom, the periphery of the diffusion sheet is attached on the shading rubber belt, an at least side for the shading rubber belt extends beyond the respective side edge of the diffusion sheet, for being fixed with glue frame, the shape of the PET film is consistent with shading rubber belt.The utility model provides a kind of integrated diaphragm, and shading and its lower floor's diffusion sheet can be combined with each other, and can reduce a dyestripping and a joint movement, lifts packaging efficiency, while improves Anawgy accuracy, and fitting caused by can reducing attaching respectively is bad, lifts yield.
Description
Technical field
Optical technical field is the utility model is related to, more particularly to integrated diaphragm.
Background technology
Major optical membrane material such as anti-dazzling screen, bright enhancement film, diffusion sheet, reflector plate in general backlight module, are all to rush respectively
Supplied materials is cut, is assembled respectively by backlight factory, i.e. pad pasting.There are two ways i.e. machine pad pasting and artificial pad pasting again in backlight factory pad pasting.
Machine pad pasting needs tune machine, and adjusting machine time is generally 1-2 hours, therefore a general order volume is less than 10K order backlight factory
Artificial pad pasting can be used.Artificial pad pasting, which includes, tears diaphragm with being bonded two actions, although manually fitting cost decreases,
It is due to that the packaging efficiency being manually bonded is low, Anawgy accuracy is poor, causes to be bonded bad, and yield is low, can not meet there is certain product
Fitting operation when matter, efficiency, precision etc. require.
Utility model content
The defects of in order to make up prior art, the utility model provide a kind of integrated diaphragm.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of integrated diaphragm, including the shading counterdie of setting, PET film, shading rubber belt, diffusion are sequentially overlapped from top to bottom
Piece, diffusion counterdie, the periphery of the diffusion sheet are attached on the shading rubber belt, and an at least side for the shading rubber belt is prolonged
The respective side edge of the diffusion sheet is extended over, for being fixed with glue frame, the shape of the PET film is consistent with shading rubber belt.
Further, the diffusion counterdie has viscosity towards the side of diffusion sheet；The shading counterdie is towards anti-dazzling screen
Side have viscosity.
Further, the region in the three-back-shaped region that the shading rubber belt is surrounded on the diffusion sheet forms visual
Area.
The utility model has the advantages that：
The utility model provides a kind of integrated diaphragm, shading and its lower floor's diffusion sheet can be combined with each other, can reduce
Dyestripping and a joint movement, packaging efficiency is lifted, while improve Anawgy accuracy, can reduced and be bonded caused by attaching respectively
It is bad, lift yield.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples, embodiment is only of the present utility model
Preferred embodiment, it is not to restriction of the present utility model.
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 utility model provide a kind of method for die cutting of diaphragm integration, comprised the following steps：
Step 1：Diffusion sheet is fitted on diffusion counterdie, wherein, the side of diffusion counterdie towards the diffusion sheet has
Viscosity；Diffusion sheet is punched, the first semi-finished product are made after winding, in first semi-finished product, the diffusion sheet is compounded in diffusion bottom
Reserved side is left in the middle part of film, the both sides for spreading counterdie, and reserving punching on side in diffusion counterdie has the first positioning hole；More preferably
Ground, diaphragm is also covered with the diffusion barrier；Before follow-up fitting, diaphragm is release.
Step 2：Anti-dazzling screen is fitted on shading counterdie, wherein, the side of shading counterdie towards the anti-dazzling screen has
Viscosity；The anti-dazzling screen is followed successively by PET film, shading rubber belt and diaphragm from top to bottom, and institute is punched to since the diaphragm
PET film is stated, the second semi-finished product are made after winding；In second semi-finished product, the anti-dazzling screen is compounded in the middle part of shading counterdie,
Reserved side is left in the both sides of shading counterdie, and reserving punching on side in shading counterdie has the second positioning hole；The shading rubber belt exists
Region in the three-back-shaped region surrounded on the diffusion sheet forms visible area；
Wherein step 1 and step 2 are synchronously carried out.
Step 3：It is bonded the first semi-finished product and the second semi-finished product：Align first positioning hole and the second positioning hole respectively,
First semi-finished product are fitted on the second semi-finished product and form integrated diaphragm.The utility model is bonded by positioning, and ensure that production
The precision of product, improve production efficiency and reduce cost.
The integrated diaphragm, including the shading counterdie of setting, PET film, shading rubber belt, diffusion are sequentially overlapped from top to bottom
Piece, diffusion counterdie, the periphery of the diffusion sheet are attached on the shading rubber belt, and an at least side for the shading rubber belt is prolonged
The respective side edge of the diffusion sheet is extended over, for being fixed with glue frame, the shape of the PET film is consistent with shading rubber belt.
In the utility model, step 1 to step 3 can separate not collinear, points of three sections making, and reduce causes because breaking at one
Sliver shut down, improve overall yield, be divided into three sections of usable one-shot equipment and complete, reduce dependence of the producing line to equipment.
Embodiment described above only expresses embodiment of the present utility model, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the utility model patent scope can not be interpreted as, as long as using equivalent substitution or the form of equivalent transformation institute
The technical scheme of acquisition, it all should fall within the scope of protection of the utility model.
