In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. As used herein, the terms "left", "right", "upper", "lower", and the like are for illustrative purposes only and do not represent the only embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Referring to fig. 1, the present invention provides a touch device 100, including: the touch module 50 comprises a first surface and a second surface opposite to each other; a first protective layer 20 on the first surface; a second protective layer 40 on the second surface; and a third protective layer 60 located on a side surface of the second protective layer 40 away from the touch module 50, where the third protective layer 60 includes a main body portion 62 and at least one tearing portion 64, the tearing portion 64 is integrally connected with the main body portion 62, and the tearing portion 64 extends out of the main body portion 62.
The first surface and the second surface of the touch module 50 are respectively covered with a single-layer protection layer (i.e., the first protection layer 20) and a double-layer protection layer (i.e., the second protection layer 40 and the third protection layer 60), so that the touch module 50 is not scratched and contaminated when being shipped, and the double-layer protection layer can also avoid the adverse problems that the touch module 100 cannot be normally separated due to adsorption when being circulated, or the protection layer falls off and has a side effect due to mechanical separation.
In addition, the third protective layer 60 is provided with the tearing part 64, so that the third protective layer 60 can be marked on one hand, and whether the third protective layer 60 is torn off or not can be distinguished in use; on the other hand, if the tearing portion 64 is not provided, the third protective layer 60 is separated from the second protective layer 40 by hand when the third protective layer 60 is torn off, so that the second protective layer 40 is torn off accidentally when the third protective layer 60 is torn off, or burrs are torn off from the second protective layer 40, and the third protective layer 60 is torn off when the tearing portion 64 can be used conveniently.
It is understood that the tearing portion 64 may be one or more.
Referring to fig. 2 to 6, in some embodiments of the present invention, the tearing portion 64 may be rectangular (fig. 2, 3 and 6), arc (fig. 4), trapezoid (fig. 5), etc. It is understood that the shape of the tear-off portion 64 is not limited to the shapes of the illustrated embodiments of the present invention, and any other shape that satisfies the description of the tear-off portion 64 of the present invention should be considered to fall within the scope of the present invention.
With continued reference to fig. 2 and 3, fig. 2 shows the tearing portion 64 at one side of the main body 62, and fig. 3 shows the tearing portion 64 at a corner of the main body 62. It can be understood that, compared with the case that the tearing portion 64 is disposed at one side edge of the main body portion 62, the tearing portion 64 is disposed at the corner of the main body portion 62, so that the corner of the main body portion 62 can be easily separated from the second protective layer 40 without lifting the second protective layer 40 by directly tearing the tearing portion 64 when the third protective layer 60 is torn off, and then the third protective layer 60 can be easily and completely torn off by using a softer and gentler force along the main body portion 62 with the tearing portion 64.
With continued reference to fig. 3 and 6, in the two embodiments shown in fig. 3 and 6, the main body 62 is rectangular, and the tearing portion 64 is disposed at the corner of the main body 62. However, in the embodiment shown in fig. 6, the tearing portion 64 only directly intersects with one side of the main body portion 62, so that the third protection layer 60 can be torn off only by applying force in a direction perpendicular to the direction in which the tearing portion 64 extends out of the main body portion 62 when the third protection layer 60 is torn off, otherwise there is still a risk that the second protection layer 40 is torn off together when the third protection layer 60 is torn off. While in the embodiment shown in fig. 3, the tearing portion 64 intersects with two sides of the corner of the main body portion 62 at the same time, it can be understood that the third protection layer 60 can be torn more conveniently by applying force in multiple directions when the third protection layer 60 is torn.
It will be appreciated that the above description is equally applicable to embodiments of tear tabs 64 of other shapes.
Referring to fig. 7, in other embodiments of the present invention, the tearing portion 64 is a long strip extending along the diagonal S of the main body portion 62. Will tear hand portion 64 set to edge main part 62 diagonal S stretches out, can conveniently tear hand portion 64, can learn by the mechanics principle of action, tear along the diagonal and remove the required power of tearing hand portion 64 is minimum.
Further, the tearing portions 64 may be symmetrically distributed on the diagonal line S of the main body portion 62. Thus, in addition to the third protective layer 60 being more convenient to tear, the touch assembly 100 can be more beautiful in the final shape.
It will be appreciated that the strip is not to be construed as a rectangular strip, but may be any regular or irregular tear portion 64 extending along the diagonal S.
Further, the third protection layer 60 is a release layer. So can tear when needs the third protective layer 60 more be convenient for tear, and can avoid when tearing the third protective layer 60 with combine too tightly between the second protective layer 40 and lead to with the second protective layer 40 tears together or leads to the edge of second protective layer 40 has a burr causes the outward appearance badly.
The main body portion 62 of the third protection layer 60, the first protection layer 20, and the second protection layer 40 are overlapped with the touch module 50 in the orthographic projection of the touch module 50, that is, the main body portion 62 of the third protection layer 60 is flush with the outer contour lines of the first protection layer 20, the second protection layer 40, and the touch module 50. Therefore, the cutting die can be conveniently used for punching in the preparation process, and the preparation process and the production cost are saved.
In some embodiments of the present invention, the outer contours of the main body portion 62 of the touch module 50, the first protective layer 20, the second protective layer 40, and the third protective layer 60 are rectangular. It can be understood that, currently, most of the touch module 50 have a rectangular outer contour, and the main body 62 of the first, second and third protection layers 20, 40 and 60 is designed to protect the touch module 50, so that the outer contour of each protection layer should be adapted to the touch module 50, that is, when the outer contour of the touch module 50 is rectangular, the outer contour of the main body 62 of the first, second and third protection layers 20, 40 and 60 should also be rectangular. Therefore, on one hand, each protective layer can well protect the touch module 50, and on the other hand, a cutting die can be more conveniently used for punching in the preparation process, so that the process cost is saved.
It is understood that, since the touch module 50 can also be circular or have other shapes, in other embodiments of the invention, the main body 62 of the first, second, and third protective layers 20, 40, 60 and the outer contour of the touch module 50 can also be circular or have other shapes. It should be understood that any simple changes in the solution made on the basis of the idea of the invention without inventive step should also be considered as falling within the scope of protection of the invention.
Referring to fig. 8 and fig. 9, the present invention further provides a method for manufacturing the touch device 100, including the following steps:
s1, attaching the first protective layer 20 and the second protective layer 40 to the first surface and the second surface of the touch module 50, respectively, and then attaching the third protective layer 60 to the surface of the second protective layer 40 away from the touch module 50;
s2, punching the outer contour of the tearing part 64 along the direction from the third protective layer 60 to the first protective layer 20 by using a flat knife;
s3, die-cutting the outer contour of the main body portion 62 along the direction from the first protective layer 20 to the third protective layer 60 by using a high-low knife, wherein the high-low knife corresponds to the first segment 621 of the main body portion 62, and the low-low knife corresponds to the second segment 622 of the main body portion, wherein the first segment 621 of the main body portion refers to the outer contour of the portion where the main body portion 62 does not overlap with the tearing portion 64, and the second segment 622 of the main body portion 62 refers to the outer contour of the portion where the main body portion 62 overlaps with the tearing portion 64.
The first protective layer 20 and the second protective layer 40 are respectively attached to the first surface and the second surface of the touch module 50, and the third protective layer 60 is attached to the surface of the second protective layer 40 far away from the touch module 50, so that the touch module can be conveniently punched by using a cutting die.
The outer contour of the tear-off portion 64 is punched out in the direction from the third protective layer 60 to the first protective layer 20 using a flat knife. The outer contour of the tearing portion 64 is firstly punched out by using a flat knife, so that the touch assembly 100 can be conveniently separated after the main body portion 62 of the third protective layer 60 is subsequently punched out.
The outer contour of the main body portion 62 is punched out in the direction from the first protective layer 20 to the third protective layer 60 by using a high-low knife, the high knife portion of the high-low knife corresponds to the first segment 621 of the main body portion 62, and the low knife portion corresponds to the second segment 622 of the main body portion 62. The touch control assembly 100 is punched by the high-low knife, and the height difference can be set to be the thickness of the third protective layer 60 due to the height difference between the high knife part and the low knife part of the high-low knife during punching, so that the main body part 62 can be punched in one step during punching, and the process is saved.
The punching depth of the high-blade portion is the thickness of the touch assembly 100 along the first surface perpendicular to the touch module 50; the punching depth of the low-blade portion is the sum of the thicknesses of the first protective layer 20, the touch module 50 and the second protective layer 40 in the direction perpendicular to the first surface of the touch module 50, that is, the low-blade portion does not punch the third protective layer 60. Thus, when punching, the high-blade portion punches all the portion corresponding to the first section 621 of the main body portion 62 of the third protective layer 60 of the touch device, and the low-blade portion does not punch the third protective layer 60, and in combination with the outer contour of the tearing portion 64 punched in the previous step, the touch device 100 is formed by just matching with punching.
The punching depth of the flat blade is the thickness of the third protective layer 60 along the direction perpendicular to the first surface of the touch module 50. The flat knife is used only to die cut the outer contour of the tear-off portion 64 of the third protective layer 60.
The outline of the flat knife can be rectangular, trapezoidal or arc. The profile of the flat knife determines the profile of the tearing part 64 which is punched, and flat knives with different profiles can be flexibly selected for punching in an actual preparation process according to needs.
Referring to fig. 10 to 13, the present invention further provides a cutting die assembly for manufacturing the touch device 100, wherein the cutting die assembly includes at least one flat blade 240 and a high-low blade 220.
Referring to fig. 10, the flat knife 240 is used to die cut the outline of the tearing portion 64 of the third protective layer 60 of the touch device 100 (i.e., the solid line portion in fig. 10), i.e., the edge profile of the flat knife 240 is the same as the outline of the tearing portion 64. In this embodiment, only the tearing portion 64 is shown as an arc-shaped structure, it is understood that the bottom view of the blade structure of the flat knife 240 may also be other shapes such as a rectangle (one side is not sealed), a trapezoid (one side is not sealed), and in actual design, the corresponding flat knife 240 may be designed according to the specific shape of the tearing portion 64.
With continued reference to fig. 9 and 11, the cutting edges of the flat knives 240 are all in the same plane, i.e., the punching depth of the flat knives 240 is equal everywhere. In the actual punching process, the flat blade 240 is designed to punch the third protective layer 60 to the same depth as the thickness of the third protective layer 60, so that the second protective layer 40 is prevented from being cut when the third protective layer 60 is punched.
Referring to fig. 12, the high-low knife 220 is used for punching the main body portion 62 of the touch layer 50, the first protective layer 20, the second protective layer 40, and the third protective layer 60.
The overall height blade 220 has a shape corresponding to the edge of the touch module 50, a lower blade 224 is located at a position of the main body 62 corresponding to the tearing portion 64 (i.e., the second section 622 of the main body 62 in fig. 9), and a higher blade 222 is located at another position (i.e., the first section 621 of the main body 62 in fig. 9). In this way, the entire shape of the touch assembly 100 can be punched out during punching, but the portion of the third protective layer 60 corresponding to the tearing portion 64 is not punched out, so as to avoid punching and cutting off the tearing portion 64. In this way, the touch device 100 with the integrally formed tearing portion 64 can be formed by combining the outer contour of the tearing portion 64 punched by the flat knife 240.
With continued reference to fig. 13, the punching depth between the high knife 222 and the low knife 224 of the high-low knife 220 has a depth difference Δ D during punching, and the Δ D may be designed to be equal to the thickness of the third protective layer 60 during actual design, so that the high knife 222 can punch the entire contour of the touch device 100 during punching while maintaining the corresponding portion of the tearing portion 64 of the third protective layer 60.
When actually designing the flat blade 240 and the high-low blade 220 of the cutting die assembly, the design can be performed according to the specific shape of the touch control assembly 100 to be die-cut.
