Abstract
The invention discloses integrated touch screen foam with single-sided adhesive and a processing method of the integrated touch screen foam with the single-sided adhesive. The foam with the single-sided adhesive comprises a release film, a frame-shaped colloid, a frame-shaped foam body and a viscous protective film, wherein the release film, the frame-shaped colloid, the frame-shaped foam body and the viscous protective film are sequentially stacked. The outer contour of the release film and the outer contour of the frame-shaped colloid coincide with the outer contour of the frame-shaped foam body. The inner frame contour of the frame-shaped colloid coincides with the inner frame contour of the frame-shaped foam body. A clean protective film is arranged on the side, towards the frame-shaped foam body, of the viscous protective film. The outer contour of the clean protective film is matched with the inner frame contour of the frame-shaped foam body and the inner frame contour of the frame-shaped colloid to make one side of the clean protective film attached to the viscous protective film, and the other side of the clean protective film is towards the release film. In the processing process, three times of punching is conducted to obtain the integrated foam with the single-sided adhesive, protective film layers are arranged on both sides of the foam, and the foam can be pasted on a touch screen by removing the protective film layer with the adhesive. By the adoption of the structure of the multiple protective layers, strength and cleanness of the touch screen are improved, and the scrap rate in the producing and follow-up using process of products is greatly reduced.
Description
Technical field
The present invention relates to touch-screen one-side band calymma cotton and the processing method thereof of touch-screen auxiliary material technical field, particularly a kind of integral type.
Background technology
In recent years, the development of mobile phone technique was with rapid changepl. never-ending changes and improvements, and touch-screen is applied more and more as a kind of man-machine interaction means of novelty.Along with the maturation of mobile phone technique and the continuous reduction of cost, touch-screen mobile phone is also no longer mysterious, is popularized on a large scale.People are also more and more deep to the understanding of touch-screen mobile phone, also more and more higher to the quality requirements of touch-screen mobile phone.Yet, because most of handset touch panel has all been used frangible Glass parts.Therefore, the effect of falling of touch-screen mobile phone also just should not be underestimated.For head it off, mobile phone assembly plant fills and cushions foam in the space between touch-screen and LCD.Consider the problem of reprocessing of product, the buffering foam is often made the shaped as frame foam of one-side band glue, but there is following problem in the making of one-side band calymma cotton:
1) the cotton laminating of one-side band calymma difficulty is large.Under normal circumstances, for guaranteeing the cleanliness factor of product, the form of touch-screen need to be sticked on layer protecting film, and then sticks foam.But consider the die-cut tolerance of the die-cut tolerance of diaphragm, foam and the laminating tolerance of the two, more than the inside casing of foam must be controlled at 0.7mm apart from form.Yet the market demand of today has been far smaller than this size, the normal requirement as 0.3mm.Therefore, adopt conventional shaped as frame foam to have no idea satisfying the market;
2) the attaching difficulty is large.Tradition one-side band calymma cotton is owing to being three-back-shaped structure, and width is thinner, and the foam material is softer, be not easy to take and grasp, the cotton aligning accuracy that attaches touch-screen of one-side band calymma can only reach 0.3mm, processes extremely difficult, and difficult quality guarantee, often occur to paste partially and the phenomenon of doing over again;
4) operation is many.For guaranteeing the cleanliness factor of mobile phone vendor's assembling, before laminating shaped as frame foam, must increase by one bonding process, on touch-screen, attach window protective film, to guarantee the cleanliness factor of touch screen window.
5) stock utilization is low.Because the foam material is softer, frame is thinner, and holding by hand while getting the foam laminating can't exactitude position, easily causes the damage of foam and pastes the phenomenons such as inclined to one side, thereby causing material to be scrapped.
Summary of the invention
The touch-screen one-side band calymma cotton and the processing method thereof that the purpose of this invention is to provide a kind of integral type, reduce the attaching difficulty of one-side band calymma cotton, improves crudy and the efficiency of one-side band calymma cotton.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of touch-screen one-side band calymma cotton of integral type, comprise stacked successively release film, shaped as frame colloid, shaped as frame foam and stickiness diaphragm; The housing contour convergence of release film, shaped as frame colloid and shaped as frame foam; The inside casing contour convergence of shaped as frame colloid and shaped as frame foam;
The stickiness diaphragm also is provided with clean diaphragm towards the one side of shaped as frame foam, and the inside casing profile of the outline of clean diaphragm and shaped as frame foam and shaped as frame colloid adapts, so that clean diaphragm one side and the laminating of stickiness diaphragm, another side is towards release film.
Integrated touch screen one-side band calymma cotton of the present invention; the surface band glue of shaped as frame colloid one side only; two sides all has diaphragm; can further protect the clean of touch-screen with the corresponding clean diaphragm in touch screen window position; and the setting of multilayer resist can improve the intensity of one-side band calymma cotton, when taking and install, be difficult for bending.
Produce and use for convenient, in the present invention, on the another side of stickiness diaphragm and the laminating of clean diaphragm, being pasted with and tearing hand.
The processing method of the touch-screen one-side band calymma cotton of above-mentioned integral type comprises the following steps:
1). on the light face of foam to be punched, whole attaches double faced adhesive tape, and retains the release liners that double faced adhesive tape does not adhere to one side, carries out first die-cut, punches out the shaped as frame foam with the shaped as frame colloid, and punch out location hole on shaped as frame colloid and shaped as frame foam;
2). remove the release film of stickiness diaphragm one side, this face and the clean diaphragm that expose are fitted, carry out second die-cut, punch out the clean diaphragm profile that appearance profile and shaped as frame foam inside casing shape profile adapt; And punch out the position location hole corresponding with position on the shaped as frame foam on the stickiness diaphragm;
3). will attach to the hair side of shaped as frame foam together with clean diaphragm through die-cut stickiness diaphragm, and the stickiness diaphragm is overlapped with the location hole on the shaped as frame foam, carry out the 3rd road die-cut, punch out the profile of touch-screen.
Now integrated touch screen one-side band calymma cotton processes and obtains, in use, only the release film on the shaped as frame colloid need be removed, then by the cotton back-off of one-side band calymma on the gum joint tool, then touch-screen is inserted in tool, take off touch-screen after pressing and get final product.
In order to increase the intensity of above-mentioned one-side band calymma cotton, conveniently of the present inventionly take and install, avoid bending, processing method of the present invention is further comprising the steps of:
4). remove the shaped as frame release liners after first is die-cut on the shaped as frame colloid, get another release film of whole and substitute the shaped as frame release liners, be attached at the shaped as frame colloid surface;
5). the another side fitted at stickiness diaphragm and clean diaphragm attaches one and tears hand, tears the very convenient installation of arranging of hand.
In the present invention, the stickiness diaphragm can be selected existing high viscosity diaphragm, and clean diaphragm can be selected existing high cleanliness diaphragm.
