Abstract
The invention relates to a back glue and a production method thereof. In the prior art, when the display screen and the touch screen are installed onto the mobile phones, the housing display screen area is covered with the whole sheet release film, such that other auxiliary materials can not be adhered in the internal (ie., the position inside the ring of the double-sided glue). A purpose of the present invention is to solve the problem in the prior art. The technical scheme of the present invention comprises that the back glue comprises release film bottom paper and a protection film, wherein a double-sided glue module is adhered on the release film bottom paper and comprises a double-sided glue, the double-sided glue has the Chinese character hui shape, the lower surface of the double-sided glue is adhered on the release film bottom paper, and the protection film is adhered on the release film. According to the present invention, after the double-sided glue is peeled off from the bottom paper, the double-sided glue module is placed on the fixture by adopting the positioning hole as the benchmark, and the housing display screen area is not covered, such that other auxiliary materials can be adhered inside the double-sided glue module.
Description
Technical field
The present invention relates generally to a kind of gum, specifically, is a kind of three-back-shaped glue frame for making the bonding such as display screen, touch-screen.
Background technology
The connection of display screen and handset shell adopts double sticky tape to bond, and encloses the double faced adhesive tape that width is about 1.0mm, display screen is fixed in mobile phone shell in mobile phone shell and display screen assembling place subsides one.The structure that the double faced adhesive tape module (before being assembled to interior of mobile phone) that present technology is produced is release film+double faced adhesive tape+base stock, except the double faced adhesive tape mediated is the ring body that inside is emptied, remaining release film and base stock are complete structure, be covered in double faced adhesive tape two surfaces, once there is following shortcoming: torn it down on base stock by double faced adhesive tape, then paste on handset shell in the operating process of double faced adhesive tape, casing display screen district cover by the release film of full wafer, cause to mount other auxiliary material in inner the annular of double faced adhesive tape (i.e. in).
Summary of the invention
For overcoming the above-mentioned shortcoming mentioned, the present invention adopts a kind of following technical scheme
A kind of gum, includes release film base stock, described release film base stock posts double faced adhesive tape module, described double faced adhesive tape module includes double faced adhesive tape, described double faced adhesive tape is three-back-shaped, and middle portion is emptied, and surrounding is described double faced adhesive tape, double faced adhesive tape lower surface is attached on described release film base stock, release film base stock is rectangle, and double faced adhesive tape upper surface posts release film, and described release film is consistent with double faced adhesive tape shape three-back-shaped, both are in the same size, are used in combination; Protective membrane, described protective membrane is attached on release film, rectangle slightly larger than described double faced adhesive tape module sized by it, and protective membrane surrounding is provided with the pilot hole for locating simultaneously.
Further, described release film is provided with the handle facilitating tearing release film, handle is U-shaped, inside release film, namely towards three-back-shaped inside, described release film disconnects near handle, there is mark of break, handle disconnects this setting, operating personnel can be made to be pulled off by release film by less power, prevent from causing because strength is excessive being pulled off from housing together by double faced adhesive tape.
Further, described protective membrane is provided with the handle facilitating tearing protective film.
Further, some described double faced adhesive tape modules are evenly distributed on described release film base stock, like this, a release film base stock can paste multiple double faced adhesive tape module.
Another object of the present invention, be just to provide a kind of method of producing above-mentioned gum, the method realizes as follows:
A) go bail for cuticula raw material and double faced adhesive tape raw material, described protective membrane raw material one side is with toughness, coated with protective film raw material release film on the face that this possesses viscosity; Double faced adhesive tape raw material release film is all posted on described double faced adhesive tape raw material two sides, and both stack and form combination 1;
B), after combination 1 being cut to rectangle, protective membrane raw material is gone out the pilot hole for locating;
C) remove the protective membrane raw material release film on protective membrane raw material after removing waste material, then with the double faced adhesive tape raw material bonding in combination 1, waste material herein refers to the waste material rushing pilot hole and cut combination 1 generation;
D) from double faced adhesive tape raw material to cutter under protective membrane direction, become three-back-shaped by after double faced adhesive tape raw material inside casing Partial Resection, protective membrane is constant, still retains original shape;
A) remove inside casing waste material, tear the release film be still retained on three-back-shaped double faced adhesive tape simultaneously off;
B) by double faced adhesive tape on release film base stock, another side coated with protective film.
Beneficial effect of the present invention is, after being torn it down on base stock by double faced adhesive tape, be that double faced adhesive tape module is placed on tool by benchmark with pilot hole, casing display screen district is not capped, and can mount other auxiliary material in double faced adhesive tape module internal simultaneously.
Accompanying drawing explanation
Fig. 1 is the decomposing schematic representation of gum;
Fig. 2 is the enlarged view of release film 12;
Fig. 3 is the enlarged view of protective membrane 13.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described.
Gum as a kind of in Fig. 1, include release film base stock 4, described release film base stock 4 posts double faced adhesive tape module 1, described double faced adhesive tape module 1 includes double faced adhesive tape 11, described double faced adhesive tape 11 is three-back-shaped, middle portion is emptied, surrounding is double faced adhesive tape region, double faced adhesive tape 11 lower surface is attached on described release film base stock 4, release film base stock 4 is rectangle, and double faced adhesive tape 11 upper surface posts release film 12, and described release film 12 is consistent with double faced adhesive tape 11 shape three-back-shaped, both are in the same size, are used in combination; Protective membrane 13, described protective membrane 13 is attached on release film 12, rectangle slightly larger than described double faced adhesive tape module 1 sized by it, and protective membrane 13 surrounding is provided with the pilot hole for locating simultaneously.
As Fig. 2, described release film 12 is provided with the handle 121 facilitating tearing release film 12, handle is U-shaped, inside release film 12, namely towards three-back-shaped inside, described release film 12 disconnects near handle 121, there is mark of break 122, this setting of handle mark of break 122, can make operating personnel be pulled off by release film 12 by less power, prevent from causing because strength is excessive being pulled off from housing together by double faced adhesive tape 11.As shown in Figure 3, described protective membrane 13 is also provided with the handle 131 facilitating tearing protective film 13.
