Description

The present invention relates to double-sided tape and electronic devices assembled with the double-sided tape.

As an adhesive tape, a stretch release tape is known in which the adhesive force in the thickness direction decreases when pulled in the longitudinal direction and can be peeled off cleanly without leaving glue on the surface of the adherend (for example, Non-Patent Document 1). reference). At the end of the stretch release tape, a grip portion covered with a film or the like is provided so as not to stick to the adherend.

In assembling electronic devices such as laptop computers and tablet terminals, double-sided tape may be used instead of hooks and fastening screws as a means for fixing the display module provided with a liquid crystal panel and the back cover covering the back of the display module. .. When the conventional double-sided tape is used, it is necessary to heat the double-sided tape or use a spatula-shaped jig in order to suppress damage to the adherend and peel it off cleanly. If the above-mentioned stretch release tape is used as the double-sided tape, it can be expected that, for example, when the display module and the back cover are misaligned in the assembly process, it can be easily repaired. For example, it can be expected that the display module and the back cover can be easily disassembled for repair, maintenance and inspection, collection and recycling, and the like.

In order to peel off the stretch release tape, it is necessary to pull the grip portion while applying a force so as to sandwich the elastic tape. Temporarily, attach a large film to the adhesive surface of the stretch release tape, apply force to the part of the film that is not superimposed on the stretch release tape, and peel off the stretch release tape from the adherend such as the back cover. If this is the case, a gap will be created between the tape and the film as the stretch release tape stretches. As a result, the stretch release tape and the film are peeled off before the stretch release tape is peeled off from the adherend.

For the reasons described above, at the point of action of the force for peeling the stretch release tape, the grip portion has a three-layer structure in which the stretch release tape and a pair of films sandwiching the tape are laminated. Inside a narrow electronic device, the thick grip portion has a large layout restriction.

Therefore, an object of the present invention is to provide a double-sided tape that can be easily peeled off even if there are layout restrictions, and an electronic device assembled with the double-sided tape.

The double-sided tape according to one aspect of the present invention includes a tape body extending from a base end to a tip opposite to the base end. The double-sided tape is divided into an adhesive portion that has adhesiveness and includes the base end of the tape body, and a grip portion that does not have adhesiveness and includes the tip of the tape body and is continuous with the adhesive portion. .. The adhesive portion is provided with a pressure-sensitive adhesive on both the first adhesive surface and the second adhesive surface on the side opposite to the first adhesive surface. The grip portion has a thick portion including the tape body and a thin portion thinner than the thick portion.

According to this aspect, the double-sided tape can be peeled off from the adherend by grasping and pulling the thick portion including the tape body with a finger or tweezers. The grip portion has a thin portion thinner than the thick portion. If the thin-walled part has few layout restrictions, it can be placed in a place that is easily accessible to the operator. Since the thick portion that receives the force to peel off the double-sided tape can be moved by operating the thin portion at a place away from the thick portion, the thick portion can be moved to a place where it is easy to grip. This makes it possible to provide a double-sided tape that can be easily peeled off even if there are layout restrictions.

The electronic device according to one aspect of the present invention further includes a display module and a back cover in addition to the double-sided tape described above. The display module has a display surface on which an image is displayed, a back surface opposite to the display surface, and a side surface connecting the display surface and the back surface. The back cover covers the back of the display module. Double-sided tape secures the display module to the back cover. The back cover has a bottom wall and an edge wall that rises from the bottom wall. The bottom wall faces the back of the display module. The edge wall faces the side surface of the display module. At least a part of the thick portion is arranged along the edge wall.

According to this aspect, since the above-mentioned double-sided tape is provided, the thin-walled portion can be operated to move the thick-walled portion to a place where it is easy to grip. Further, since the thick portion is provided with an edge wall that supports the thick portion so that it does not fall due to its own weight, the thick portion can be hidden on the side surface of the display module that cannot be seen by the user until it is used.

An object of the present invention is to provide a double-sided tape that can be easily peeled off even if there are layout restrictions, and an electronic device assembled with the double-sided tape.

Preferred embodiments of the present invention will be described with reference to the accompanying drawings. In each figure, those having the same reference numerals have the same or similar configurations. The double-sided tape 10 according to the embodiment of the present invention is preferably a stretch release tape, and can be peeled off from the adherend (33, 35) by gripping the grip portion 12 and pulling it in the longitudinal direction D1. One of the features of the double-sided tape 10 is that the grip portion 12 has a thick portion 13 and a thin portion 14 thinner than the thick portion 13 (see FIGS. 4 and 6). .. In the illustrated example, the thick portion 13 includes the tape body 15, and the thin portion 14 does not include the tape body 15.

The double-sided tape 10 adheres, for example, the display panel 33 and the back cover 35 (see FIGS. 2 and 3). According to the double-sided tape 10 and the electronic device 1 (see FIG. 1) assembled with the double-sided tape 10, the thin portion 14 having less restrictions on the layout is operated to have a thickness hidden in the cover window 34 or the like. The meat portion 13 can be moved to an easily accessible place (see FIGS. 7 and 8). At this time, if the thin-walled portion 14 is branched toward the base end 13P of the thick-walled portion 13, a small movement of the thin-walled portion 14 can be transmitted in this way to move the thick-walled portion 13 significantly.

If the thick portion 13 is arranged along the lower edge wall 383 of the back cover 35, it can be brought into contact with the lower edge wall 383 and hidden so as not to fall toward the keyboard 5 side (see FIG. 5). If the thin-walled portion 14 is arranged on the hinge 4, the thin-walled portion 14 can be pulled diagonally from the back surface 33B side to the display surface 33A side in the depth direction Z of the display 3, so that the thin-walled portion 14 can smoothly get over the lower edge wall 383. The thick portion 13 can be dropped toward the keyboard 5 side (see FIG. 6). Hereinafter, each configuration will be described in detail with reference to FIGS. 1 to 8.

The display module 31 includes a display panel 33 and a cover window 34 laminated on the display panel 33.

The cover 32 includes a back cover 35 that covers the back surface of the display module 31, and a plurality of hinge covers 361, 362, and 363 that close the gap between the back cover 35 and the cover window 34 on the hinge 4 side. A cover (bezel cover) that covers the area corresponding to the outer peripheral portion 342 may be added by omitting the cover window 34. Each of the hinge covers 361, 362, and 363 is formed in a strip shape extending in the left-right direction of the display 3. The hinge cover 361 covers the thin portion 14 described later so as not to be seen by the user.

FIG. 2 is a front view showing the internal structure of the display 3 through the cover window 34 and the hinge covers 361, 362, 363 shown in FIG. As shown in FIG. 2, the display panel 33 is, for example, a liquid crystal panel, and is a flat plate having a display surface 33A, a back surface 33B opposite to the display surface, and a side surface 33C connecting the display surface 33A and the back surface 33B. It is formed in a shape. The display panel 33 may be an organic electroluminescence (EL) panel or a panel module of a micro LED display.

The display surface 33A has a pixel region 331 in which a plurality of pixels are arranged in a matrix, and a frame region 332 surrounding the pixel region 331. The extending direction of the scanning signal line that supplies the scanning signal to each pixel and the video signal line that supplies the video signal coincides with the vertical or horizontal direction of the image such as a character string or a pattern displayed on the display module 31. ing. The back cover 35 is formed in a rectangular flat box shape, and has a bottom wall 37 facing the back surface 33B of the display panel 33, and an edge wall 38 standing up from the bottom wall 37 and facing the side surface 33C of the display panel 33. have. The edge wall 38 includes an upper edge wall 381, a right edge wall 382, a lower edge wall 383, and a left edge wall 384 located on the upper side, the right side, the lower side, and the left side, respectively.

This will be described again with reference to FIG. The cover window (cover glass) 34 is formed of a translucent material such as glass or acrylic resin into a flat plate shape larger than the display panel 33. The cover window 34 has a central portion 341 that superimposes on the pixel region 331 described above, and an outer peripheral portion 342 that surrounds the central portion 341. The central portion 341 is formed transparently, and the outer peripheral portion 342 is painted black with a black matrix. The outer peripheral portion 342 is superimposed on the thick portion 13 described later in addition to the frame region 332 described above.

FIG. 3 is a front view showing an example of the double-sided tape 10 passing through the display panel 33 shown in FIG. As shown in FIG. 3, the above-mentioned hinge 4 includes a first wing 41 fixed to the personal computer main body 2 and a second wing 42 fixed to the display 3. The second wing 42 is configured to be rotatable with respect to the first wing 41. The shape of the second wing 42 will be described in detail later with reference to FIG.

The double-sided tape 10 includes a tape body 15 formed in a long flat plate shape extending from the base end 15P to the tip end 15D opposite to the base end 15P. The double-sided tape 10 is divided into an adhesive portion 11 for adhering two members and a grip portion 12 continuous with the adhesive portion 11. The adhesive portion 11 occupies most of the double-sided tape 10, and includes the base end 15P of the tape body 15.

The grip portion 12 is divided into the tip end portion of the double-sided tape, that is, the tip end 15D of the tape body 15 and a portion in the vicinity thereof, and includes the tip end 15D of the tape body 15. The grip portion 12 has a thick portion 13 and a thin wall portion 14. The base end 13P of the thick portion 13 is continuous with the adhesive portion 11. In other words, the base end 13P is located at the boundary between the adhesive portion 11 and the grip portion 12.

In the illustrated example, the adhesive portion 11 of the double-sided tape 10 (10L) is arranged along the left edge wall 384 forming the left side of the back cover 35, and adheres the display panel 33 and the back cover 35. Further, in the illustrated example, the grip portion 12 is bent in a direction D2 different from the longitudinal direction (extending direction of the adhesive portion 11) D1 of the double-sided tape 10, and a part of the thick portion 13 is the back cover 35. It is arranged along the lower edge wall 383 that constitutes the lower side. Further, in the illustrated example, a part of the thin-walled portion 14 is arranged on the second wing 42 of the hinge 4.

FIG. 4 is an enlarged front view of the double-sided tape 10 (10L) shown in FIG. As shown in FIG. 4, the adhesive portion 11 includes the tape body 15 described above. The tape body 15 is provided with a pressure-sensitive adhesive on both sides of the first adhesive surface 15A and the second adhesive surface 15B on the side opposite to the first adhesive surface 15A. The tape body 15 may be a base material-less tape made entirely of a pressure-sensitive adhesive, or may be a tape in which pressure-sensitive adhesives are applied to both sides of the base material.

When the tape body 15 contains a base material, a pressure-sensitive adhesive layer is formed at least in a range overlapping the adhesive portion 11. The pressure-sensitive adhesive layer may be formed in the entire range from the base end 15P of the tape body 15 to the tip end 15D. The tape body 15 is preferably a stretch release tape (Stretch-relase tapes). Stretch release tape is rich in elasticity like rubber, and has the property that when pulled in the longitudinal direction, the adhesive force in the thickness direction decreases.

Examples of the stretch release tape include the Bond & Detach (registered trademark) series of tesa tape Co., Ltd., preferably model numbers 70315, 70350, 70415, 70420, 70440, 70465, 70615, 70620, 70625, 70640, 70650, 70665 and the like. Can be mentioned. The example of the stretch tape is not limited to this, and may be a double-sided tape of 3M Innovative Properties Company, Ltd., which has similar properties, or a double-sided tape of another type.

The thick portion 13 has a three-layer structure in which the first sheet 16 and the second sheet 17 are laminated on the tape main body 15. The first and second sheets 16 and 17 coat the pressure-sensitive adhesive layer of the tape body 15 so that the grip portion 12 does not adhere to the adherend. In the grip portion 12, the first sheet 16 covers the first adhesive surface 15A, and the second sheet 17 covers the second adhesive surface 15B. The first and second sheets 16 and 17 may be integrally formed from the same sheet material folded back in a U shape.

The thin-walled portion 14 is different from the thick-walled portion 13 described above in that the tape body 15 is not included. In the illustrated example, the thin portion 14 is configured as a tongue piece member branched from the second sheet 17. In other words, the thin portion 14 is formed in a region of the second sheet 17 that covers the second adhesive surface 15B and does not overlap with the tape body 15. The thin-walled portion 14 may be integrally formed from the same sheet material as the second sheet 17, or may be formed from a sheet material (third sheet) different from the second sheet 17, and then bonded or welded to the second sheet. It may be fixed to 17 and formed. The thin-walled portion 14 may further include a sheet material (fourth sheet) (not shown) fixed to the first sheet 16.

The first and second sheets 16 and 17 are sheet materials thinner than the tape body 15, and are formed of, for example, polyethylene terephthalate (PET) resin. An example of the thickness of the tape body 15 is 0.5 mm, and an example of the thickness of the first and second sheets 16 and 17 is 0.02 mm. In the illustrated example, the thick portion 13 is thicker than the tape body 15 because it has the thickness of the first sheet 16 and the second sheet 17 in addition to the thickness of the tape body 15. On the other hand, the thin portion 14 does not include the tape body 15 and is formed thinner than the tape body 15.

The thick portion 13 does not necessarily have to be thicker than the tape body 15. For example, when the thickness of the tape body 15 is not uniform from the base end 15P to the tip end 15D, the total thickness of the tape body 15 and the first and second sheets 16 and 17 in the thick portion 13 is the thickness of the adhesive portion 11. It may be thinner than the thickness of the tape body 15.

In the illustrated example, the second sheet 17 constituting the thin-walled portion 14 branches from the thick-walled portion 13 and extends in a direction D3 different from the extending direction D2 of the thick-walled portion 13. In the illustrated example, the thin-walled portion 14 is connected to the thick-walled portion 13 on the base end 15P side of the tape body 15 with respect to the intermediate position 13M located equidistant from the base end 13P and the tip end 13D of the thick-walled portion 13. ..

However, the double-sided tape 10 is not limited to the example shown in FIG. For example, as in the modified double-sided tape 10R shown in FIG. 3, the thin portion 14 is not branched between the base end 13P of the thick portion 13 and the intermediate position 13M, but is attached to the tip 13D of the thick portion 13. You may connect. In any case, the thin-walled portion 14 has a direction in which the tape body 15 extends from the base end 15P to the tip end 15D (for example, a direction in which the extending direction D1 of the adhesive portion 11 and the extending direction D2 of the thick-walled portion 13 are combined). Is formed by branching the second sheet 17 in a different direction D3.

FIG. 5 is a cross-sectional view taken along the line VV in FIG. As shown in FIG. 5, the lower edge wall 383 of the back cover 35 faces the thick portion 13 from below so that the thick portion 13 does not fall toward the keyboard 5. A gap G communicating with the outside of the display 3 is provided between the lower edge wall 383 and the display module 31. The electronic device 1 is configured such that when the thick portion 13 moves from the back surface 33B side of the display 3 to the display surface 33A side so as to get over the lower edge wall 383, the thick portion 13 is exposed from the gap G.

FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. As shown in FIG. 6, the thin-walled portion 14 is arranged along the first main surface (upper surface) 42A side of the second wing 42 of the hinge 4. In the double-sided tape 10, the thin portion 14 is fixed not to the first sheet 16 on the display surface 33A side but to the second sheet 17 on the back surface 33B side. Further, the thin-walled portion 14 is arranged so as to ride on the first main surface 42A of the second wing 42.

That is, in the depth direction Z of the display 3, the tip 14D (see FIG. 4) of the thin-walled portion 14 is located closer to the display surface 33A than the base end 14P (see FIG. 4) of the thin-walled portion 14. When the thin-walled portion 14 is pulled, the thick-walled portion 13 can be pulled diagonally downward from the back surface 33B side of the display 3 toward the display surface 33A side. It can be pulled out to the 5 side.

FIG. 7 is a diagram illustrating an example of how to use the double-sided tape 10 shown in FIG. 3, and is an enlarged view of the thin-walled portion 14 and its vicinity. As shown in FIG. 7, in the assembled state of the electronic device 1, since the thick portion 13 is superimposed on the cover window 34, it cannot be visually recognized from the display surface 33A side. On the other hand, the thin portion 14 extends below (outside) the lower edge of the cover window 34. The range from the upper edge to the lower edge of the cover window 34 is indicated by reference numeral H in FIG. 2 described above.

FIG. 8 is a diagram showing a state in which the thick portion 13 is moved by operating the thin portion 14 shown in FIG. 7. As shown in FIG. 8, when the thin-walled portion 14 is operated, the thick-walled portion 13 moves to a place where it can be visually recognized. In the present embodiment, the thin-walled portion 14 branches from between the base end 13P of the thick-walled portion 13 and the intermediate position 13M, and the extending direction D3 of the second film 17 constituting the thin-walled portion 14 constitutes the thick-walled portion 13. Since the direction intersects the extending direction D2 of the second film 17, the thick portion 13 can be greatly moved by a small movement of the thin portion 14.

In the illustrated example, as a result of grasping the thin portion 14 with tweezers, fingers, etc. and operating it downward to the left, the thick portion 13 rotates clockwise around the base end 13P and the tip 15D is below the cover window 34. It is exposed below (outside) the edge. By grasping the thick portion 13 moved to a visible place and pulling it in the longitudinal direction D1 of the double-sided tape 10, the double-sided tape 10 such as the stretch release tape can be peeled off cleanly. The thick portion 13 is an example of the action point of the force for peeling the tape, and the thin wall portion 14 is an example of the action point of the force for moving the thick portion 13.

According to the double-sided tape 10 and the electronic device 1 assembled with the double-sided tape 10 according to the embodiment of the present invention configured as described above, as shown in FIGS. 7 and 9, the thin portion 14 is operated. The thick portion 13 hidden in the cover window 34 or the like can be moved to a place where it can be visually confirmed. As shown in FIG. 6, the thin-walled portion 14 not including the tape main body 15 is thinner than the thick-walled portion 13 including the tape main body 15. Since the thin portion 14 can be arranged in a narrower gap than the thick portion 13, there are few restrictions on the layout. On the other hand, since the thick portion 13 is a thick portion of the tape main body 15, the resistance when pulled is superior to that of the thin portion 14. Therefore, the thick portion 13 is convenient for applying a strong force to peel off the double-sided tape 10. That is, by arranging the thin-walled portion 14 in a narrow but easy-to-grip gap, the thick-walled portion 13 can be moved to a place where the thick-walled portion 13 can be easily gripped by pulling the thin-walled portion 14 first. After that, it becomes possible to grip the thick portion 13 and pull the double-sided tape 10 with a relatively strong force.

The thin portion 14 may be formed thinner than the thick portion 13. For example, when the thickness of the tape body 15 is configured to change continuously or stepwise, the thick portion 13 of the tape body 15 is used to form the thick portion 13 of the tape body 15. The thin portion 14 may be formed by a portion having a relatively thin thickness.

The embodiments described above are for facilitating the understanding of the present invention, and are not for limiting and interpreting the present invention. Each element included in the embodiment and its arrangement, material, condition, shape, size, etc. are not limited to those exemplified, and can be changed as appropriate. In addition, the configurations shown in different embodiments can be partially replaced or combined.
