A kind of applying methodTechnical field
The present invention relates to a kind of applying method; be particularly related to full attaching process between a kind of liquid crystal panel or liquid crystal module and cover sheet; or/and the full attaching process between cover sheet and touch sensor, or/and the full attaching process between liquid crystal panel or liquid crystal module and touch sensor.
Background technology
The use range of the product such as touch-screen mobile phone, panel computer is more and more extensive.In the structure of the product such as touch-screen mobile phone, panel computer, generally comprise cover sheet, liquid crystal panel (or liquid crystal module) and touch sensor, the general mode that adopts the tackiness agent of high-clarity to fit that interfixes between them.For example: publication No. is CN102622146, name is called the Chinese invention patent application of " a kind of capacitive touch screen and production method thereof ", announce a kind of capacitive touch screen structure, this capacitive touch screen has capacitive touch sensors, bonding layer, glass cover-plate and flexible printed circuit board, and it utilizes tackiness agent (bonding layer) by relative with glass cover-plate capacitive touch sensors fixing.Granted publication number is CN203232402, name is called the Chinese utility model patent of " a kind of OPS entirely fit capacitance plate ", a kind of OPS capacitance plate of entirely fitting is disclosed, comprise the touch-control module (touch sensor), tack coat and the liquid-crystal display module that are cascading, tack coat is glue or solid-state OCA optical cement.Touch-control module is seamless applying by tack coat and liquid-crystal display module.
When laminating, the solid-state glue laminating of the general OCA of employing or the liquid glue of LOCA are fitted.For example: publication No. is CN103660511, the Chinese invention patent application that name is called " applying method of capacitive touch screen " discloses a kind of applying method of capacitive touch screen, comprise between protection armourplate glass (cover plate) and touch pad (touch sensor), and/or applying method between touch pad and LCD MODULE, comprise the following steps: 1) according to the laminating size between protection armourplate glass and touch pad, formulate printing area; 2) determine web plate and the glue material of the printing of plastic emitting, require gel quantity even, glue mobility is even; 3) particularly at edge part, design the glue amount that remaining glue flows again, prevent that glue from overflowing at periphery; 4) binding face to protection armourplate glass, or the binding face of touch pad, or the binding face of LCD MODULE carries out brush coating; 5) control gel quantity, control rubber quality thickness; 6) laminating, vacuum pressed, UV light irradiation; 7) after sclerosis, complete printing attaching process.The shortcoming of the method is: production efficiency is general, and binding yield is poor, is generally 75%～90%, and cannot heavy industry, is only applicable to the laminating of small-medium size product, can not meet the demand of the full laminating of large size product.
Summary of the invention
The object of the invention is to provide the full applying method of a kind of liquid crystal module.
For achieving the above object, the technical solution used in the present invention is: a kind of applying method, comprises the following steps:
The first step: the high temperature resistant adhesive tape of glue-coated surface for the treatment of at the first parts to be fit encloses the closed stickup district of formation;
Second step: by glue-coating to described stickup district to form the adhesive-layer of an even thickness in described stickup district, and make the thickness of described adhesive-layer be greater than the thickness of described high temperature resistant adhesive tape;
The 3rd step: described adhesive-layer is heated so that the glue of described adhesive-layer solidifies and obtains solidifying adhesive-layer;
The 4th step: described high temperature resistant adhesive tape is removed, then by described the second parts to be fit and described the first parts laminating to be fit.
Preferred technical scheme is: in second step, after described adhesive-layer forms, described adhesive-layer is struck off, and unnecessary glue is scraped to described high temperature resistant adhesive tape.
Preferred technical scheme is: after described high temperature resistant adhesive tape is removed, and adhesive coating outside described curing adhesive-layer scope.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, the present invention encloses the closed stickup district of formation at the high temperature resistant adhesive tape of glue-coated surface for the treatment of of the first parts to be fit, to limit gluing scope, thereby makes gluing accurate, and speed is fast;
2, the thickness of adhesive-layer of the present invention is greater than the thickness of high temperature resistant adhesive tape, thereby can adjust easily the thickness of adhesive-layer;
3, the unnecessary glue of adhesive-layer of the present invention is scraped to high temperature resistant adhesive tape, thereby removes easily unnecessary glue;
4, the present invention's adhesive coating again outside curing adhesive-layer scope, thus make the first parts to be fit and the second parts to be fit bond strength between the two higher.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment: a kind of applying method
Shown in accompanying drawing 1～3, a kind of applying method, comprises the following steps:
The first step: at the first parts 1(glass cover-plate to be fit) treat that the high temperature resistant adhesive tape 3 of glue-coated surface encloses and form closed stickup district 2;
Second step: by glue-coating to described stickup district 2 with in described stickup district 2, described glue is struck off, and unnecessary glue is scraped to described high temperature resistant adhesive tape, form like this adhesive-layer 4 of an even thickness, and make the thickness of described adhesive-layer 4 be greater than the thickness of described high temperature resistant adhesive tape 3;
The 3rd step: described adhesive-layer 4 is heated so that the glue of described adhesive-layer 4 solidifies and obtains solidifying adhesive-layer; Specifically by the first parts 1(glass cover-plate to be fit) move to baking oven, then heat so that glue solidifies, because there is the existence of heating steps, therefore need adhesive tape to have high temperature resistant.Because the temperature that glue is heating and curing is very wide, the temperature resistant range of high temperature resistant adhesive tape is very wide, can the using of 50 DEG C～150 DEG C of temperature resistant ranges.Can use publication number to be: CN103589362, name is called disclosed adhesive tape in " a kind of high temperature resistant adhesive tape ".
The 4th step: described high temperature resistant adhesive tape 3 is removed, then by described the second parts 5(liquid crystal panel to be fit) fit with described the first parts 1 to be fit.
Be preferred embodiment: after described high temperature resistant adhesive tape is removed, adhesive coating outside described curing adhesive-layer scope.
In other embodiments, the first parts 1 to be fit are liquid crystal panel, and the second parts 5 to be fit are cover sheet, and mode of the present invention can be used for cover sheet and the touch sensor of fitting, and also can be used for liquid crystal module and the touch sensor of fitting.Or fit successively cover sheet, touch sensor and liquid crystal module, to realize the full laminating of product.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that spirit is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
