Description
Technical field
This patent is related to display screen manufacturing, especially a kind of the detection means and method of touch-screen fitting bubble.
Background technology
In recent years, the development of capacitive touch screen was swift and violent, and market competition is fierce all the more, in order to improve production yield and client
Satisfaction, the processing procedure inspection for capacitive touch screen propose higher requirement.It is bonded in touch-screen manufacturing process main
It is to be pasted together display panel, touch-screen, protective glass in a manner of seamless completely by glue or optical cement.Its reclaimed water
Adhesive process is because its light transmittance is high, and adhesive strength is good, the advantages such as cure shrinkage is small, is increasingly becoming the use technique of hot topic, but
Be glue as liquid object, have certain gas solubility, easily produce bubble, and office is there may be during glue levelling
Portion's gaps and omissions, it is therefore desirable to the touch screen products produced are investigated, defective products is investigated out and is recycled, pass through exclusion
Confirm, without next step UV curing process can be carried out after gaps and omissions, bubble-free, to improve product yield.
Investigation method traditional at present is that desk lamp or hanging lamp are placed in above desktop, and worker carries out illumination inspection under light
Look into, naked eyes identify gaps and omissions and bubble in glue, and whole or most of work top is all illuminated by light, but this inspection party
Formula is the problem of very big be present in fact, because work top is too bright, substantial amounts of anaclasis and diffusing reflection be present, and the eyes of worker can be by
To the stimulation of various light, because receiving of the eye retina nerve to light is limited, can disperse to penetrate light by instinct
Enter, cause worker to be not easy to find small bubble on the contrary, and long-term such working condition may cause to the eyes of worker
Injury, but because the fixed cognition of broad masses, people do not make preferably breakthrough and ameliorative way, can not kept away in this regard
Exempt from the missing inspection to micro-bubble so that the yields of product cannot be lifted further, or even some consumers buy touch
During screen products, the faulty materials with micro-bubble are the discovery that unexpectedly.In order to overcome this defect, it is necessary to find a kind of new inspection party
Method improves the precision of detection.
The content of the invention
Based on above reason, the present inventor devises a kind of detection means and method of touch-screen fitting bubble, detects people
Member can quickly have found gaps and omissions and bubble, and easily find micro-bubble, improve the efficiency and precision of investigation, ensure that product
Yields.
Concrete scheme is as follows：A kind of detection means of touch-screen fitting bubble, including a detection light source, and one is reflective
Film, reflective membrane are arranged on below the functional sheet of touch-screen to be detected, the glass of the reflective surface of reflective membrane towards touch-screen to be detected
The direction of cover plate, detection light source are located above the glass cover-plate of touch-screen to be detected, are close to glass cover-plate, and light points to glass
Cover plate direction；
Further, the detection light source is a source of parallel light, and directional light, which compares, concentrates practical effect more preferable；
Further, described a kind of novel touch screen fitting bubble verifying attachment, it is characterised in that：The source of parallel light is multigroup
Multigroup directional light that LED lamp bead is sent by focus lamp；
Further, described a kind of novel touch screen fitting bubble verifying attachment, it is characterised in that：There is positioning fitting to control
Tool, position the support face on joint tool and the visible area of touch-screen to be detected etc. greatly, the reflective membrane fits in positioning patch
On the support face for closing tool, the stabilization of reflective membrane is improved, is not easy to shift；
Further, described a kind of novel touch screen fitting bubble verifying attachment, it is characterised in that：Detection light source front end week
Ring-type cushion pad is provided with along portion, to avoid scratch glass cover-plate.
Further, described a kind of novel touch screen fitting bubble verifying attachment, it is characterised in that：The detection light source
Front end week is provided with a collar flange along portion, the purpose so set, the scattering for avoiding light from entering before product, concentrates light more
Be advantageous to effective reflection of light.
Further, described a kind of novel touch screen fitting bubble verifying attachment, it is characterised in that：Before the detection light source
End week is provided with cushion pad along the outer ring of the collar flange in portion.
Further, described a kind of novel touch screen fitting bubble verifying attachment, it is characterised in that：The reflective membrane is height
Intensity nanometer reflective membrane, the nanometer reflective membrane reflecting effect of high intensity is good, is more beneficial for the detection of micro-bubble；
The touch-screen fitting bubble detecting method of novel touch screen fitting bubble verifying attachment described in more than one, by reflective membrane
Size 1:1 be attached on positioning joint tool support face, it is reflective face-up, then by the functional sheet of touch-screen to be detected
It is sequentially placed into glass cover-plate in positioning joint tool and completes dispensing attaching process, levelling technique, joint tool will be positioned afterwards
Inspection area is pushed into, described detection light source is moved to above the glass cover-plate of touch-screen to be detected, is close to glass cover-plate and exists
Move back and forth in touch-screen visible area to be detected, be shining into by light, reaching reflective membrane, further reflection comes up, and is touched to be detected
Touch the bubble corresponding to screen visible area in gelatine layer clearly to reflect, testing staff is by detecting the reflected light around light source
Line then can easily find gaps and omissions and bubble in touch-screen gelatine layer to be detected.
Further, the touch-screen fitting bubble detecting method of described novel touch screen fitting bubble verifying attachment, its
It is characterised by, reflective membrane is fitted on positioning joint tool for stripable board, beneficial to dismounting.
After employing such apparatus and method, because the apparatus structure is simple, energy-conservation, it is not dazzling, to uniform gelatine layer
Gaps and omissions and the bubble reflection of appearance are particularly evident, will be scarce in the glue of touch screen function piece and glass cover-plate by LED lamp source
Leakage and bubble are clearly reflected with high-strength nano reflective membrane so that small bubble can also be found easily, can be with
The bubble that minimum diameter is 50um is detected, detection efficiency and accuracy of detection is substantially increased, improves production yields, is lifted
The quality of product.And such detection method, light is not used largely, avoids dazzling, also protects the eyes of worker,
It is not easy to cause discomfort, improves the work comfort degree of worker.
