A kind of PET protection film tears hand structure
Technical field
The utility model is related to the PET protection film in liquid crystal display module, more particularly to PET protection film tears hand structure.
Background technology
To very fierce, the technology of electronic product is constantly being reformed, and product also shows quickly for the competition one of electronic product
The features such as renewalization, cheapization, quality severization.In this context, each production firm wish cost to product,
Quality can have further lifting.
At present on conventional liquid crystal display module, display surface can all have a PET protection film 1, to ensure product in assembling
Not by dirty, injury before machine.Meanwhile, this PET protection film is the auxiliary material for playing a protective role, and whole machine is assembled client is sent to
When, to be torn in the assembling link of display module, tear take for convenience, one side can be pasted by double faced adhesive tape 2 at edge
Just it is manually-operated to tear hand 3(Such as Fig. 1).
But, it is conventional tear hand beyond whole module outside, this is accomplished by module packaging material it is important to note that reserving
Bit space is kept away, not only cumbersome but also increase design cost;And, after module gives client, although tear hand and facilitate artificial tearing and take, but
Simultaneously also because tearing hand leakage, occurring interference when assembling with outer framework could continue group, it is necessary to manually adjust and tear hand position
Dress, inefficiency.
The content of the invention
The utility model is to solve existing problem, there is provided a kind of PET protection film tears hand structure, including pastes
First layers of two-sided of PET protection film top surface edge, paste and tear hand layer in the first layers of two-sided upper surface, and tear hand
The hand portion of tearing of layer is located in the edge of PET protection film.
Preferably, the second layers of two-sided is pasted in the hand layer upper surface of tearing, and the hand layer that tears is directed away from PET protection film
The direction bending of top surface edge is simultaneously pasted with the upper surface of the second layers of two-sided, the hand portion of tearing for tearing hand layer is located at PET
In the edge of diaphragm.
Preferably, the hand layer that tears is provided with junction of the edges of two sheets of paper folding line in bending place.
Be made within the edge of liquid crystal module in the hand portion of tearing by the utility model so that the package design of module is without considering further that
Hand tears portion's distinct issues, greatly reduces design difficulty, and in assembling, whole machine assembling is not interfered with yet, not with other
Shell material produces interference, reduces artificial operation, improves efficiency, cost is reduced, while also conveniently tear taking.
Brief description of the drawings
Fig. 1 is the sectional view of prior art;
Fig. 2 is the sectional view of the utility model first embodiment;
Fig. 3 is the sectional view of the utility model second embodiment;
Fig. 4 is the assembling flow path figure that the utility model hand tears portion.
Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 2 the PET protection film that proposes of an embodiment of the present utility model tears hand structure, including first two-sided
Glue-line 2 and tear hand layer 3.First layers of two-sided 2 is pasted in the top surface edge of PET protection film 1, tear hand layer 3 paste it is two-sided first
The upper surface of glue-line 2, and tear hand layer 3 hand tear portion 31 positioned at PET protection film 1 edge in.Torn off by PET protection film 1
During liquid crystal module, it is only necessary to pick up hand and tear portion 31, by the power of pasting between double faced adhesive tape, PET protection film 1 is driven to tear off liquid crystal
Module.Although this mode will not make hand tear portion 31 being exposed to beyond liquid crystal module, however it is necessary that the viscosity of double faced adhesive tape is especially
Jail.
As shown in figure 3, this is a preferred embodiment of the present utility model, the hand structure of tearing of the PET protection film includes the
One double faced adhesive tape, tear hand layer, the second layers of two-sided.First double faced adhesive tape is pasted in PET protection film top surface edge, is torn hand layer and is pasted
The upper surface of the first layers of two-sided, now, the hand portion of tearing for tearing hand layer is located at outside the edge of PET protection film, then will tear hand layer
The direction bending of PET protection film top surface edge is directed away from, and is pasted with the upper surface of the second layers of two-sided, make to tear hand layer
The hand portion of tearing is located in the edge of PET protection film.Equally also solve the problems, such as that the hand portion of tearing exposes, hand tears portion apart from PET protection film
Upper surface there is certain gap, take up and also more facilitate, when PET protection film is torn off, it is more firm to paste power, without load
The heart tears hand layer and departs from PET protection film.Can smoothly be bent when for the ease of processing, tearing hand layer can also set in bending place
There is junction of the edges of two sheets of paper folding line.
As shown in figure 4, when tearing hand layer and not pasting also in PET protection film 1, its main body is torn hand layer and 3 and is located at by one layer
First, second layers of two-sided, 4 three parts for tearing hand layer upper and lower surface constitute, and are also not attached to when on diaphragm, and two-layer is two-sided
There are release liners to be protected on glue-line.During assembling, remove the release liners of the first layers of two-sided, the junction of the edges of two sheets of paper bending on hand layer will be torn
Line and the justified margin of PET protection film, are attached to a lateral edges of PET protection film, remove the release liners 41 of the second layers of two-sided,
Hand layer will be torn to be bent along junction of the edges of two sheets of paper folding line, hand layer then will be torn and be pasted again in the second layers of two-sided, and hand is torn portion 31
Within the edge of PET protection film.
Specific embodiment above is only used to illustrate design of the present utility model, and one of ordinary skill in the art exists
Various deformation and change can be made under design of the present utility model, these deformations and change are included in guarantor of the present utility model
Within the scope of shield.
