Description
Technical field：
The utility model relates to diaphragm test device, and in particular to the test device of diaphragm bending angle.
Background technology：
With the development of display backlight technology, in response to the market demand, high-brightness, slimming are simultaneously reduction assembly cost, subtracted
Few processing procedure loss, stability of material etc. is improved, optical thin film gradually develops to Multifunctional multilayer laminating film.Lamination coating film be by
Two layers or the film that forms of plural layers fitting；Because fitting forms, during actual assembled use, if touching
Hit, bend be easily caused laminating film layering, so as to influence its use.It is directed in the method for testing of multilayer film layering capabilities in the industry, base
This is all the patch that the method to a certain extent can be between reflecting multilayer film using the peeling force between puller system measurement film and film
Intensity is closed, but because the difference of attaching process, the anti-injured performance of laminating film and performance in actual use are incomplete same.
And it is in the field of business also not to the method for testing and tester of laminating film buckle resistance energy, it is contemplated that a set of test dress of design
Put and method of testing, can Validity Test go out laminating film and the angle of injured or dynamics occur, so as to judge out buckle resistance can
Quality.
Quantization contrast can be carried out to diaphragm warping resistance performance difference by lacking apparatus and method of testing at present.This practicality is new
The device of type design and corresponding method of testing aim to solve the problem that this problem, can directly be reflected by the contrast of test number
The height of product warping resistance performance.
Utility model content：
The purpose of this utility model provides bending angle test device, and diaphragm warping resistance performance difference can be quantified
Contrast, the height of product warping resistance performance can be directly reflected by the contrast of test number.
To achieve the above object, the technical solution of the utility model is：
A kind of bending angle test device, it is characterised in that including base, support, fall bar, briquetting, pressure head and sample stage,
The support is inverted U-shaped structure, and the support both ends are arranged on base, and the sample stage is arranged on the base, described
Fall bar and be arranged on the upper of the support.
Further, the pressure head is V-type, circle or tapered.
Further, it is described fall bar be arranged on by spring on support.
Further, the support is provided with a cavernous structure, it is described fall bar be arranged in cavernous structure.
Further, the sample stage is two support members.
Further, the top of the sample stage is provided with fixing device.
Further, the fixing device is nut and tabletting.
Further, it is provided with adjustable sliding track between the sample stage and base.
Further, the sample stage is mechanically fastened on base using discontinuity.
Further, the briquetting is counterweight.
Beneficial effect：
The utility model provides a kind of bending angle test device, and subjective judgement is quantified, and then greatly reduces
The error component of artificial subjective judgement, improve test accuracy and result it is illustrative.
By adjusting the distance between sample stage support member in the utility model, angle when closing film bending, folder can adjust
Angle is smaller, the easier injured of lamination coating film, so as to test the critical bending angle that injured occurs for membrane, according to different critical
Angle judges the quality of testing sample bend resistance ability, or can judge testing sample by the quality of injured degree under same angle
The quality of warping resistance ability.
Brief description of the drawings：
The utility model is further illustrated with reference to structural representation Fig. 1 and embodiment 1.
Fig. 1 shows a kind of typical bending angle test device of the present utility model, including base 1, support 2, falls bar
3, briquetting 4, pressure head 5, sample stage 6, sliding rail 7, fixing device 8.
Embodiment：
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
A kind of bending angle test device includes base 1, support 2, falls bar 3, briquetting 4, pressure head 5 and sample stage 6, the branch
Frame 2 is inverted U-shaped structure, and the both ends of support 2 are arranged on base 1, and the sample stage 6 is arranged on the base 1, the branch
The cavernous structure of upper setting one of frame 2, it is described fall bar 3 be arranged on by spring in the cavernous structure of the support 2.The sample stage
6 be two support frames, and two support frame is mechanically fixed between two support frames of setting by adjustable sliding track 7 or discontinuity
Distance, sample diaphragm is fixed by the nut of fixing device 8 on support frame and tabletting.
The step of test sample：
Step 1, the fixation of diaphragm：Need to place by U-typed for fixing diaphragm, during fixed placement diaphragm, be easy to pressure head 5
Press down on, by adjusting the spacing between membrane support frame, diaphragm is bent under certain external force by certain angle.
Step 2, press：V-type pressure head 5 need to the angle of falling R, avoid pressing when cause diaphragm to be weighed wounded by sharp object, pressure head 5 can be by not
With testing requirement be replaced with circular or tapered；Fall bar 3 by spring retainer, fall the lower end of bar 3 and (do not increase not applying external force
Add counterweight) when, flushed with membrane support frame upper end；Briquetting 4 is the weight of counterweight clamping block 4, and increase counterweight weight is to falling
Bar 3 applies pressure.Pressing pressure head 5 directly contacts diaphragm, and increase counterweight weight makes diaphragm bend downwards, until injured or layering,
The material of pressure head 5 can be Steel material.
3, assess test result：Set adjustable rail plate 7 or discontinuity machinery solid between support frame and base 1
It is fixed, for adjusting the distance between diaphragm fixing support rack, diaphragm is gone out by the altitude conversion of the distance of base 1 and support frame and pressed from both sides
Angle, after the completion of remove sample, whether observation multilayer membrane sample pressing position sample has injured.Different bendings in simulation actual use
Angle, the smaller angle of distance is bigger under same counterweight weight, and the bigger buckle resistance of angle can be better.
The preferred embodiment of utility model is the foregoing is only, is not intended to limit the utility model, it is all of the present utility model
