The cutting die for reflectance coating thrust processing, wherein the width of the rectangle shrinkage pool is 4-15cm.
The cutting die for reflectance coating thrust processing, wherein four apex angles of the rectangle shrinkage pool are equal
Carry out chamfered.
The cutting die for reflectance coating thrust processing, wherein the length of the cutoff tool is 3-12cm.
The cutting die for reflectance coating thrust processing, wherein the height of the cutoff tool is 0.1-3mm.
The cutting die for reflectance coating thrust processing, wherein the bottom of the cutoff tool and rectangle shrinkage pool
The distance on side is 0.1-2cm.
Advantageous effect：
The cutting die for reflectance coating thrust processing of the utility model, it is rectangular by being arranged in cutting die substrate center
Shape shrinkage pool, and cutoff tool is arranged in the upper end certain distance on rectangle shrinkage pool bottom edge, it is close in reflectance coating lower end by cutoff tool
The position of LED light generates and thrusts gap, and when carrying out high temperature test to the backlight product after assembling, gap can absorb reflectance coating certainly
The stress of body will not cause backlight product life can not greatly improved by high temperature test because of the surface folding of reflectance coating
The yields of backlight product during production.
Description of the drawings
Fig. 1 is a kind of structure chart for reflectance coating thrust the cutting die of processing.
Fig. 2 is the structure chart by cutting die treated reflectance coating.
Specific implementation mode
The utility model provides a kind of cutting die for reflectance coating thrust processing, to make the mesh of the utility model
, technical solution and effect it is clearer, clear, the utility model is further described below.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
- Fig. 2 is please referred to Fig.1, Fig. 1 is a kind of structure chart for reflectance coating thrust the cutting die of processing；Fig. 2 is logical
Cross cutting die treated the structure chart of reflectance coating.As shown, a kind of cutting die for reflectance coating thrust processing,
In, the cutting die includes：Cutting die substrate 1；Rectangle shrinkage pool 2 in 1 center of cutting die substrate is set；It is arranged in rectangle shrinkage pool 2
Downside and the perpendicular cutoff tool 3 of cutting die substrate 1.In specific production process, cutting die substrate is slab construction, cutting die substrate
There is rectangle shrinkage pool, the size of rectangle shrinkage pool to be adapted with the size of produced backlight product in center, hang down on cutting die substrate
Straight setting cutoff tool, cutoff tool are arranged on the downside of rectangle shrinkage pool, and the upper end certain distance setting on rectangle shrinkage pool bottom edge is cut
Breaking is generated close to the position of LED light 5 in reflectance coating lower end by cutoff tool and thrusts gap 6, to the backlight product after assembling
When carrying out high temperature test, reflectance coating 4 stress of itself can be absorbed by thrusting gap 6, and Folding Deformation will not occur for reflectance coating 4, can
Greatly improve the yields of backlight product in production process.
In more specific embodiment, a length of 7-20cm of the rectangle shrinkage pool 2；The width of the rectangle shrinkage pool 2 is
4-15cm.To meet the specification requirement of the multiple sizes of backlight product, the size for making rectangle shrinkage pool and the backlight produced are needed
The size of product is adapted, and in specific production process, the length of rectangle shrinkage pool is set as 7-20cm, wide to be set as 4-15cm.
In more specific embodiment, four apex angles of the rectangle shrinkage pool 2 carry out chamfered.It is practical to meet
Production requirement, four apex angles of rectangle shrinkage pool are subjected to chamfered.
In more specific embodiment, the length of the cutoff tool 3 is 3-12cm；The height of the cutoff tool 3 is 0.1-
3mm.During being produced to reflectance coating, cutting die substrate is driven according to being fixed on thrust equipment by thrust equipment
Cutting die substrate moves downward, and carries out thrusting processing to reflectance coating.In this operation, it need to rationally be arranged on reflectance coating and thrust gap
Length, it is long and influence reflection film strength to avoid thrusting slit design length, also avoid because thrust slit design it is too short due to
Cause stress absorption insufficient, according to actual use situation, the length that cutoff tool is arranged is 3-12cm.It is processed thrust
Cheng Zhong, the height of cutoff tool is because of rationally setting, so that the reflectance coating obtained after thrusting processing procedure meets actual use need
It asks, in specific production process, the height that cutoff tool can be arranged is 0.1-3mm, is rushed by the cutoff tool of certain altitude
Disconnected processing, can obtain reasonable depth on the reflecting film thrusts gap.
As shown in Fig. 2, the reflectance coating 4 handled by cutoff tool, has in reflectance coating lower end close to the upside of LED light 5
Thrust gap 6.LED light 5 will produce heat at work, can by thrusting gap when testing backlight product
The stress of reflectance coating itself is absorbed, and the high temperature that will not be generated because of LED light 5 in the backlight product course of work leads to reflectance coating
Fold occurs, therefore does not interfere with the normal work of backlight product, therefore backlight product will not be caused to damage.
In more specific embodiment, the cutoff tool 3 is 0.1-2cm at a distance from the bottom edge of rectangle shrinkage pool 2.Pass through
Cutoff tool is arranged in certain distance on rectangle shrinkage pool bottom edge, so as to thrust the distance controlling of gap and LED light in zone of reasonableness
It is interior, make to thrust the heat that gap distributes LED light and preferably absorbed, in the actual production process, cutoff tool with it is rectangular
The bottom edge distance of shape shrinkage pool is set as 0.1-2cm, can meet and actual thrust operational requirements.
In conclusion the utility model discloses a kind of cutting dies for reflectance coating thrust processing, wherein described
Cutting die includes：The rectangle shrinkage pool in cutting die substrate center is arranged in cutting die substrate；It is arranged on the downside of rectangle shrinkage pool and cutting die
The perpendicular cutoff tool of substrate.The cutting die for reflectance coating thrust processing of the utility model, by cutting die substrate
