Technical Field

The invention relates to the technical field of display screens of electronic equipment, in particular to a protective film pasting jig.

Background

With the development of communication technology and electronic product technology, the application of touch screens is more and more extensive, and display screens of mobile phones, household appliances, vehicle-mounted equipment and the like are all promoted to touch screens comprehensively. In order to reduce the risks of touch, sliding and breakage in daily use, manufacturers often apply protective films to touch screens.

However, the conventional protective film has the phenomenon of unevenness in application due to the problem of material quality; when the conventional pasting jig is used, the protruding position of the protective film can contact the part before the part is positioned close to the edge, so that the part is pasted in advance, the part cannot be positioned, the pasting deviation is caused, and the pasting precision requirement cannot be met.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to solve the technical problems that: the defects that the parts cannot be positioned and the pasting deviation is caused due to the fact that the protective film is in contact with the parts in advance when the protective film is pasted are overcome, and the pasting precision is guaranteed when the protective film is pasted, so that the technical effects of guaranteeing the pasting quality and improving the operation efficiency are achieved.

In order to solve the technical problems, the invention provides a protective film pasting jig, wherein a vacuum hole is arranged in the protective film pasting jig, the vacuum hole is communicated with a lower vacuum cavity, and the vacuum cavity is communicated with an external vacuum source; steps are arranged on the inner edge of the jig; the back of the jig is provided with a blind plate, and the blind plate covers and blocks the jig.

On the basis of the technical scheme, the invention can be further improved as follows.

Preferably, the jig is rectangular, and the step is arranged on a long side and/or a short side of the rectangle.

Preferably, the width of the step corresponds to the retracted dimension of the protective film to be applied;

further preferably, the width dimension of the step is greater than or equal to the retracted dimension of the protective film to be applied.

Optionally, the protective film is a PE protective film.

Optionally, the vacuum source is a vacuum pump.

Compared with the prior art, the technical scheme of the invention can effectively paste the protective film and the part and avoid deviation, and effectively solves the problems that the part cannot be positioned and the deviation is caused because the part and the protective film are pasted in advance when a conventional jig is used, so that the pasting quality is ensured, and the operation efficiency is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

Please refer to fig. 1 and fig. 2, wherein fig. 1 is a top view of the protective film attaching jig of the present invention, and fig. 2 is a side cross-sectional view of the protective film attaching jig of the present invention.

As shown in the figure, the protective film pasting jig 1 is internally provided with a vacuum hole 2, and the vacuum hole 2 is communicated with a lower vacuum cavity 5; the vacuum chamber 5 is in communication with an external vacuum source, which may be, for example, a vacuum pump, but is not limited thereto.

Taking the jig as a rectangle as an example, steps 3 are arranged on two straight sides in the jig 1, wherein the two straight sides are preferably a long side and a wide side; according to the use requirement, the jig 1 can also be designed to be round, oval, round rectangle or other shapes, and then the step can be arranged at the inner edge of the jig; the width dimension of the step 3 is designed according to the retraction dimension of the protective film to be applied, and preferably, the width dimension of the step 3 is greater than or equal to the retraction dimension of the protective film to be applied.

The blind plate 4 is arranged on the back surface of the jig 1 and used for covering and plugging the jig 1.

When in application, the application surface of the protective film 6 faces outwards, the step 3 is positioned along the side, an external vacuum source is started, and the protective film 6 is adsorbed on the inner plane of the jig 1 through the vacuum holes 2; then, the protective film 6 is flattened; then, positioning a part 7 close to the edge of the inner wall of the jig 1, enabling the part 7 to be close to the protective film 6 downwards, and pressing the part 7 to enable the protective film 6 and the part 7 to be completely attached; finally, the external vacuum source is turned off.

In the present invention, the protective film may be, for example, a PE protective film, but is not limited thereto.

In summary, the technical scheme of the invention is characterized in that steps are designed on two straight edges in the jig, vacuum holes are designed on the surface of the jig, and the protective film is positioned at the steps by the edges and is adsorbed and flattened through the vacuum holes; the parts are positioned by the inner wall of the jig to be pasted and covered, so that the pasting and covering of the protective film are prevented from deviating. Therefore, the invention can effectively improve the pasting precision of the part and the protective film, solves the technical problem of inaccurate pasting position caused by uneven protective film, and avoids pasting deviation between the protective film and the part.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
