Protective film, panel structure including it, and method of removing it

technical field

The invention relates to a protective film, a panel structure containing the protective film and a method for tearing off the protective film.

Background technique

During the panel manufacturing process, a temporary protective film will be pasted on the panel to prevent the panel from being affected by the external environment. After finishing some manufacturing process of the panel, the protective film needs to be removed. Usually, an extra sticky sticker is used to attach it to the protective film, and then the sticker is pulled to remove the protective film. After tearing off the protective film, install the outer frame on the panel, and then attach another protective film back to the part of the center of the panel that is not covered by the iron frame.

The above-mentioned manufacturing process of removing the protective film to install the frame, and then attaching another protective film to the panel makes the panel assembly process complicated and adds extra cost.

A number of implementations of the present invention will be disclosed below with the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the invention. That is, in some embodiments of the present invention, these practical details are unnecessary. In addition, for the sake of simplifying the drawings, some conventional structures and elements will be shown in a simple and schematic way in the drawings. Also, the same reference numerals in different drawings may be considered as corresponding elements unless otherwise indicated.

The present invention provides a protective film, which is easy to tear off during panel assembly, improves process efficiency and reduces damage to products. A first embodiment of the protective film in the present invention will be described below with reference to FIG. 1A and FIG. 1B .

Please refer to FIG. 1A , which shows a schematic top view of a protective film 100A according to an embodiment of the present invention. As shown in FIG. 1A , the protective film 100A includes an inner film 110 and an outer film 120 . The inner membrane 110 has a main body portion 111 and a lug portion 112 , and the lug portion 112 extends from the first side 111 a of the main body portion 111 . There is a folding line 113 between the lug portion 112 and the main body portion 111 , and the folding line 113 is connected to the first side 111 a of the main body portion 111 . The outer membrane 120 surrounds the main body 111 together with the lug portion 112 . The outer membrane 120 is connected to the lug portion 112 by a connecting section 130 .

In this embodiment, the protective film 100A has a rectangular shape as a whole, but in different applications, those skilled in the art can change the shape of the protective film 100A according to practical needs, and the present invention is not limited thereto.

As shown in FIG. 1A , the inner membrane 110 has a main body portion 111 and a lug portion 112. The main body portion 111 is substantially rectangular, but there is an inclined turn between the first side 111a and the second side 111b of the main body 111. The fold line 113 is connected, that is, there is a chamfer between the first side 111a and the second side 111b, and the lug portion 112 extends from the chamfer. That is to say, the lug portion 112 extends from the folding line 113 and is connected to the first side 111 a and the second side 111 b of the main body 111 .

In this embodiment, since the lug portion 112 is disposed adjacent to the corner of the main body portion 111 , the user can tear off the inner film 110 of the protective film 100A more easily by pulling the lug portion 112 . However, those skilled in the art can change the location of the lug portion 112 according to practical requirements, and the present invention is not limited thereto. For example, in some embodiments, the main body portion 111 is rectangular, or the lug portion 112 is located closer to the center of the first side 111 a or the center of the second side 111 b.

In the embodiment of FIG. 1A , one lug edge 112 a of the lug portion 112 is actually flush with the second side 111 b of the main body portion 111 . That is to say, both the lug edge 112a and the second side 111b form a straight line. With the above design, the lug edge 112 a and the second side 111 b can be easily cut out at the same time when making the protective film 100A, which simplifies the manufacturing process of the protective film 100A.

The folding line 113 connects the first side 111a and the second side 111b, and the folding line 113 can be designed with a structure that is easy to fold. For example, the folding line 113 can be a virtual knife line, a creasing line and so on. By setting the fold line 113 between the lug portion 112 and the main body portion 111 , the lug portion 112 can be folded along the fold line 113 .

In the embodiment shown in FIG. 1A , the folding line 113 forms an angle a with the first side 111 a. Angle a is not equal to 0 degrees or 180 degrees. That is to say, the folding line 113 is not parallel to the first side 111a, and the folding line 113 and the first side 111a will not form a straight line. By designing the folded line 113 and the first side 111a to form an angle a, the user can easily fold and pull up the lug portion 112 , and can ensure that the folded lug portion 112 is positioned on the main body portion 111 middle. It should be understood that those skilled in the art can adjust the size of the angle a according to practical needs.

As shown in FIG. 1A , the outer membrane 120 surrounds the main body portion 111 together with the lug portion 112 . In the embodiment of FIG. 1A , the outer membrane 120 is completely disconnected from the main body portion 111 , and the outer membrane 120 and the lug portion 112 are connected to each other by a connecting section 130 . That is to say, the outer membrane 120 and the inner membrane 110 are connected to each other only by the connecting section 130 . It should be understood that the position of the connecting segment 130 is shown by a dotted line in FIG. 1A . The dotted line only represents the position of the connecting segment 130 , and does not mean that the connecting segment 130 has a suture-riding or knife-riding structure. With the above design, the user will not affect the main body 111 of the inner membrane 110 when tearing off the outer membrane 120, so that the main body 111 can remain on the covered area; and when the outer membrane 120 is completely separated from the main body 111 , the lug portion 112 of the outer membrane 120 will be pulled up by the connection section 130 , and the size of the connection section 130 can be designed to be easily torn by manpower to separate the outer membrane 120 and the inner membrane 110 . For example, the size of the connection section 130 may be about 1 mm. Those skilled in the art can modify the size of the connecting section 130 according to practical requirements.

The connecting section 130 is located on a side of the lug portion 112 opposite to the lug edge 112a. In this embodiment, by disposing the connecting section 130 at a position farther from the lug portion 112 to the folding line 113 , when the outer membrane 120 is torn off to completely separate the outer membrane 120 from the main body 111 , the connecting section 130 When pulling up the lug portion 112 of the outer membrane 120 and then turning over the lug portion 112 , a larger torque can be generated, so that the user can easily turn over the lug portion 112 at the same time.

Next, please refer to FIG. 1B , which shows a schematic top view after the outer film 120 in FIG. 1A is removed and the ear portion 112 is folded based on the fold line 113 . In FIG. 1B , the outer film 120 has been completely removed from the protective film 100A (so the outer film 120 is not shown in FIG. 1B ), and the connection section 130 connecting the outer film 120 and the lug portion 112 has been disconnected.

As shown in FIG. 1B , the lug portion 112 takes the folding line 113 as an axis, and can form a symmetrical coverage area A1 . The footprint A1 is entirely located in the main body portion 111 of the inner membrane 110 . That is to say, the folded lug portion 112 is located in the main body portion 111 and covers the covering area A1. With the above settings. The folded lug portion 112 can be completely located in the main body portion 111 of the inner membrane 110 . In this way, while the starting point of tearing is reserved, the work to be performed in the area other than the main body portion 111 of the inner membrane 110 will not be affected.

In some embodiments, such as in a panel structure with a narrow frame, if the outer film 120 as a whole does not have a sufficient width (for example, less than 5 mm), the area of the lug portion 112 will not be enough for the user to hold . Therefore, another embodiment of the protective film in the present invention solves the above-mentioned problem of insufficient width, which will be described below with reference to FIG. 1C and FIG. 1D .

FIG. 1C is a schematic top view of a protective film 100B according to an embodiment of the present invention. The difference between the protective film 100B and the protective film 100A is that the lug portion 112 of the protective film 100B also has a body area 112b and a grip area 112c. It should be understood that in FIG. 1C , the dotted line between the body region 112b and the grip region 112c only represents the boundary between the two, and does not mean that there is a suture-riding line or a knife structure there. As shown in FIG. 1B , the body region 112 b is connected to the main body portion 111 , and the handle region 112 c is connected to the connection section 130 . In other words, the lug portion 112 of the protective film 100A in FIG. 1A extends out of the gripping area 112c in FIG. 1B along the direction of the first side 111a. The lug portion 112 of the protective film 100B has a larger area than the protective film 100A. Therefore, in an embodiment where the overall width of the outer film 120 is narrow, the protective film 100B may be used to maintain a sufficient area of the lug portion 112 .

Next, please refer to FIG. 1D , which shows a schematic top view after the outer membrane 120 in FIG. 1C is removed and the ear portion 112 is folded based on the fold line 113 . In FIG. 1D , the outer film 120 has been completely removed from the protective film 100B (therefore, the outer film 120 is not shown in FIG. 1D ), and the connection section 130 connecting the outer film 120 and the lug portion 112 has been disconnected.

As shown in FIG. 1D , the coverage area A2 of the lug portion 112 of the protective film 100B is located in the area of the main body portion 111 in mirror-symmetrical coverage area A2 with the folding line 113 as the axis. That is to say, the gripping area 112c extending from the main body area 112b is still located in the area of the main body 111 after being mirror-symmetrical to the axis along the folding line 113 . In this way, while increasing the overall area of the lug portion 112 , it will not affect the operations to be performed in areas other than the main body portion 111 of the inner membrane 110 .

The implementations of the protective film 100A and the protective film 100B in the present invention have been described above with reference to FIGS. 1A to 1D . The usage of the protective film 100A and the protective film 100B in specific applications will be introduced below with reference to FIG. 2 and FIGS. 3A to 3D . The protective film provided by the present invention, such as the protective film 100A, can be attached to the surface of the panel 300, and the protective film 100A can be removed in sections to continuously protect the panel 300 during different stages of transportation or assembly.

FIG. 2 shows a flowchart of a protective film peeling method 200 according to an embodiment of the present invention. 3A to 3D are three-dimensional schematic diagrams of various stages of the protective film removal method 200 in FIG. 2 .

Please refer to FIG. 2 and FIGS. 3A-3C . The protective film tearing method 200 starts from step S210. In step S210 , the outer film 120 of the protective film 100A on the panel 300 is lifted, and the outer film 120 is separated from the main body 111 , and the lug portion 112 of the inner film 110 is pulled up by the connecting section 130 . The outer membrane 120 can be lifted by the portion adjacent to the lug edge 112a, because the lug edge 112a is relative to the connecting section 130, and therefore will not be pulled to the connecting section 130 until the outer membrane 120 is fully lifted along the periphery of the main body portion 111, and will The lug 112 is pulled up.

The protective film peeling method 200 proceeds to step S220. In step S220, the connecting segment 130 is disconnected. Specifically, the connecting section 130 can be torn apart by hand. In some embodiments, the connection section 130 can also be disconnected by a cutting tool. After the connection section 130 is disconnected, the outer membrane 120 (which has been removed in FIG. 3B , so not shown) is completely separated from the inner membrane 110 . After step S220 is performed, the outer membrane 120 has been completely separated from the inner membrane 110 and removed from the protective membrane 100A. At the same time, the inner membrane 110 is still covering the panel 300 .

Then proceed to step S230 , folding the lug portion 112 along the folding line 113 , so that the lug portion 112 overlaps with the main body portion 111 .

Please refer to FIG. 2 , FIG. 3D and FIG. 4 , wherein FIG. 4 shows a schematic top view of the panel structure 500 in FIG. 3D . Then proceed to step S240 , covering the peripheral area S1 of the panel 300 with the outer frame 400 . Since the folded line 113 forms an angle a with the first side 111a, after being folded, the two sides of the lug 112 connected to the folded line 113 will not be completely covered by the outer frame 400, especially the above two sides. The part away from the folding line 113 , that is to say, the folded lug portion 112 is partially not covered by the outer frame 400 . For example, the peripheral area S1 covered by the outer frame 400 is a non-display area of the panel 300 , such as including the area of the panel 300 not covered by the main body 111 and the outer edge of the main body 111 . In FIG. 4 , the portion covered by the outer frame 400 (that is, the peripheral region S1 ) is indicated by oblique lines, and the outline of the main body portion 111 is indicated by dotted lines.

As shown in FIG. 3D and FIG. 4 , after step S240 is performed, the panel structure 500 includes the panel 300 , the inner film 110 of the protective film 100A and the outer frame 400 . The inner membrane 110 is attached to the panel 300 , and the inner membrane 110 has a main body 111 and a lug 112 , the main body 111 and the lug 112 are connected by a folding line 113 and the lug 112 overlaps the main body 111 . Specifically, the structure in FIG. 1B plus the outer frame 400 is the structure shown in FIG. 4 .

As shown in FIG. 3D and FIG. 4 , the folding line 113 is located in the peripheral area S1 . That is to say, the outer frame 400 covers the folding line 113 . In the implementation of the panel structure 500 , since the outer frame 400 completely covers the folding line 113 , a part of the panel 300 can be prevented from being exposed to the external environment. The outer frame 400 also covers the peripheral region S2 of the main body 111 , so that external impurities cannot touch the panel 300 under the outer frame 400 or the inner film 110 . In the embodiment of FIG. 4 , the width of the peripheral region S2 is 0 to 0.5 mm.

Since the main body 111 remains on the panel 300 after the outer film 120 (see FIG. 3A ) is removed, the panel 300 can be jointly protected by the outer frame 400 and the inner film 110 during transportation. Compared with the traditional process of completely tearing off the protective film, assembling the outer frame, and then attaching another protective film, this embodiment can effectively simplify the process and reduce the cost.

Please continue to refer to FIG. 2 and FIG. 3D. Then proceed to step S250 , pulling the lug portion 112 to tear off the inner film 110 from the panel 300 . Since the lug portion 112 is reserved in the area of the main body portion 111 , the user can easily remove the inner membrane 110 . That is to say, the folded lug portion 112 reserves a starting point for tearing off, so that the user can easily tear off the inner membrane 110 .

Please refer to FIG. 5 , which shows a cross-sectional view of the panel structure 500 along line 5 - 5 in FIG. 4 . As shown in FIG. 5 , a part of the lug portion 112 is located between the outer frame 400 and the main body portion 111 . With the above arrangement, when the user pulls the lug portion 112 , it will only rub against the surface of the main body portion 111 away from the panel 300 without affecting the panel 300 , effectively reducing possible damage during the process of tearing off the inner membrane 110 .

Please refer to FIG. 6 , which shows a schematic top view of a panel structure 600 according to another embodiment of the present invention. The difference between the panel structure 600 in FIG. 6 and the panel structure 500 in FIG. 4 lies in the design of the lug portion 112 . As shown in FIG. 6 , the lug portion 112 includes a body area 112 b and a grip area 112 c. That is to say, the lug portion 112 in FIG. 4 extends along the direction of the first side 111 a to a gripping area 112 c to form the structure shown in FIG. 6 . In this embodiment, at least part of the gripping area 112c is not covered by the outer frame 400, that is to say, the sides of the gripping area 112c are not covered by the outer frame 400, so that it is easier for the user to pull up and hold District 112c. Compared with the panel structure 500 , the area of the lug portion 112 of the panel structure 600 is larger, so it is beneficial for the user to pull the lug portion 112 .

In summary, the present invention provides a protective film and its application method. The protective film includes an outer film, an inner film and a lug extending from the inner film, and the outer film and the inner film can be removed in sections. A connecting section is provided between the lug and the outer membrane, so that the lug can be pulled while the outer membrane is removed, so that the lug can be easily folded to facilitate subsequent operations. When the outer film is removed, the inner film remains on the panel and is then removed by pulling on the folded-over lugs. Therefore, after the outer film is removed, the area covered by the inner film on the panel can still be properly protected, so that the protective effect of the protective film on the panel is more perfect.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
