Description

[0002] See also Figure 1 , Figure 1 The figure shows an exploded schematic diagram of an electronic device in the prior art. In the process of bonding the display panel 100 and the frame 200, adhesive 300 is often used for bonding. In order to achieve the waterproof and dustproof effect, the adhesive 300 needs to be a complete circle structure to surround and form an airtight isolation area to isolate external water or dust from the adhesive structure.

[0003] See also Figure 2 , Figure 2 The figure shows a schematic diagram of the adhesive backing structure of the prior art. In a small display device, in order to ensure the sealing effect, the adhesive backing 300 usually directly uses a "mouth-shaped" frame structure, which is easier to operate during adhesive backing processing and lamination. However, in the process of manufacturing the adhesive backing, the middle area except the frame structure is a redundant residual material area 400. When the size of the display device increases, the cost waste caused by the residual material generated during the manufacturing process of the "mouth-shaped" adhesive backing will become prominent. Therefore, how to save manufacturing costs while maintaining the sealing of the electronic device is an urgent problem to be solved. Summary of the invention

[0029] The electronic device 1 of the present invention avoids the waste of raw materials caused by overall cutting in the prior art during the production of the adhesive parts by splitting the adhesive parts corresponding to the first periphery 21 and the second periphery 22 connected to the first corner 25 into a first adhesive 31, a second adhesive 32 and a first auxiliary adhesive 35, thereby greatly reducing the production cost; in addition, the edges corresponding to the adhesive and the auxiliary adhesive are straight, which facilitates the bonding and ensures that dust, water and other small debris are not easily entered at the bonding point, ensuring a waterproof and dustproof effect.

[0032] See also Figure 4 , Figure 4 The figure shows a schematic diagram of the structure of the combined adhesive member described in the first embodiment of the present invention. In the first embodiment, the first adhesive 31 has a first edge 311, the second adhesive 32 has a second edge 321, the second edge 321 is adjacent to the first edge 311, the first edge 311 is in a straight line, and the second edge 321 is also in a straight line; the first auxiliary adhesive 35 has a first auxiliary edge 351 and a second auxiliary edge 352 adjacent to each other, and when the electronic device 1 is assembled (or when it is considered that the first adhesive 31, the second adhesive 32 and the first auxiliary adhesive 35 are attached), the first auxiliary edge 351 is aligned with the first edge 311, and the second auxiliary edge 352 is aligned with the second edge 321. It should be noted that for the convenience of explanation, Figure 4 In the subsequent figures, the gap between the first auxiliary adhesive 35 and the first adhesive 31 and the second adhesive 32 is drawn in an exaggerated manner. In actual operation, the gap between the first auxiliary adhesive 35 and the first adhesive 31 and the second adhesive 32 is extremely small or even non-existent to ensure the waterproof and dustproof effect.

[0033] In actual operation, similarly, the third adhesive 33 has a third edge 331, and the third edge 331 is in a straight line. The first adhesive 31 also has a fifth edge 312 in a straight line opposite to the first edge 311, and the third edge 331 is adjacent to the fifth edge 312. The second auxiliary adhesive 36 has a third auxiliary edge 361 and a fourth auxiliary edge 362 adjacent to each other. When the electronic device 1 is assembled (or when the first adhesive 31, the third adhesive 33 and the second auxiliary adhesive 36 are considered to be attached), the third auxiliary edge 361 is aligned with the third edge 331, and the fourth auxiliary edge 362 is aligned with the fifth edge 312. Similarly, Figure 4 In the subsequent figures, the gap between the second auxiliary adhesive 36 and the first adhesive 31 and the third adhesive 33 is drawn in an exaggerated manner. In actual operation, the gap between the second auxiliary adhesive 36 and the first adhesive 31 and the third adhesive 33 is extremely small or even non-existent to ensure the waterproof and dustproof effect.

[0034] In actual operation, similarly, the second adhesive 32 also has a sixth edge 322 in a straight line opposite to the second edge 321, the third adhesive 33 also has a seventh edge 332 in a straight line opposite to the third edge 331, the fourth adhesive 34 has a fourth edge 341 and an eighth edge 342 in a straight line, the third auxiliary adhesive 37 has a fifth auxiliary edge 371 and a sixth auxiliary edge 372 adjacent to each other, the fourth auxiliary adhesive 38 has a seventh auxiliary edge 381 and an eighth auxiliary edge 382 adjacent to each other, and when the electronic device 1 is assembled (or when it is considered that the second adhesive 32, the third adhesive 33, the fourth adhesive 34 and the third auxiliary adhesive 37, the fourth auxiliary adhesive 38 are attached), the fifth auxiliary edge 371 is aligned with the fourth edge 341, the sixth auxiliary edge 372 is aligned with the seventh edge 332, the seventh auxiliary edge 381 is aligned with the sixth edge 322, and the eighth auxiliary edge 382 is aligned with the eighth edge 342. Similarly, Figure 4 In the subsequent figures, the gaps between the third auxiliary adhesive 37 and the third adhesive 33, the fourth adhesive 34, and between the fourth auxiliary adhesive 38 and the second adhesive 32, the fourth adhesive 34 are drawn in an exaggerated manner. In actual operation, the gaps between the third auxiliary adhesive 37 and the third adhesive 33, the fourth adhesive 34, and between the fourth auxiliary adhesive 38 and the second adhesive 32, the fourth adhesive 34 are extremely small or even non-existent, so as to ensure the waterproof and dustproof effect.

[0035] In the present invention, each adhesive and auxiliary adhesive are combined to form a closed rectangular frame to replace the overall frame-shaped adhesive in the prior art, which is convenient for production and manufacturing and reduces costs. In the present embodiment, the edges of the first adhesive 31, the second adhesive 32, the third adhesive 33, the fourth adhesive 34, the first auxiliary adhesive 35, the second auxiliary adhesive 36, the third auxiliary adhesive 37 and the fourth auxiliary adhesive 38 that cooperate with each other are all straight lines (such as the first edge 311, the second edge 321, the first auxiliary edge 351, the second auxiliary edge 352, etc.), so that it is convenient for the automated machine or the operator to align and fit the adhesive parts during the assembly process, and the tolerance during the production of the adhesive and the offset generated during the fitting can be absorbed, so as to avoid the overlapping of adjacent adhesives or the excessive gap at the fitting position, thereby ensuring the waterproof and dustproof effect.

[0036] In the first embodiment, the existing rectangular frame structure-shaped adhesive is split into a combination of strip adhesive parts and small block adhesive parts that can be combined with each other, so that in the process of making adhesive parts, the waste of raw materials caused by overall cutting can be avoided, which greatly reduces the production cost. Furthermore, the edges of the adhesive and the auxiliary adhesive are in a straight line, which is convenient for alignment and attachment during the assembly process, and dust, water and other small debris are not easy to enter the joint, ensuring the waterproof and dustproof effect, simple structure, and easy use.

[0037] See also Figure 5 , Figure 5 The figure shows a partially enlarged structural schematic diagram of the combined adhesive backing member described in the first embodiment of the present invention. In the first embodiment, the first adhesive backing 31 also has a first bottom edge 313 adjacent to the first edge 311, and the first edge 311 forms an angle 314 with the first bottom edge 313. In actual operation, if the angle 314 is too small, the area of ​​the first adhesive backing 31 at this place is too small (the edge is too sharp), and it is not easy to pick up and fit; if the angle 314 is too large, the area of ​​the first auxiliary adhesive backing 35 matched with the first adhesive backing 31 at the corresponding place is too small (the edge is too sharp), and it is not easy to pick up and fit. Therefore, the angle 314 is preferably between 45° and 105°, that is, the angle formed by the first auxiliary edge 351 and the second auxiliary edge 352 in the first auxiliary adhesive backing 35 is between 60° and 180°, and in actual operation, the first auxiliary adhesive backing 35 can be symmetrically designed.

[0038] Please continue reading Figure 4 and Figure 5 In the first embodiment, the first edge 311 of the first adhesive 31 forms an angle 314 with the first bottom edge 313, and the angle 314 is 70°. The fifth edge 312 of the first adhesive 31 forms an angle 315 with the first bottom edge 313, and the angle 315 is 70°. The fourth adhesive 34 also has a fourth bottom edge 343 adjacent to the fourth edge 341. The fourth edge 341 of the fourth adhesive 34 forms an angle 344 with the fourth bottom edge 343, and the angle 344 is 70°. The eighth edge 342 of the fourth adhesive 341 forms an angle 345 with the fourth bottom edge 343, and the angle 345 is 70°. In the present embodiment, each auxiliary adhesive is a symmetrical structure, and specifically, each auxiliary adhesive can be symmetrically designed about the angle bisector of its two auxiliary edges, so that the structure of the second corner 26, the third corner 27 and the fourth corner 28 of the frame 20 of the combined adhesive component 30 is the same as the structure of the first corner 25.

[0039] In this embodiment, the first adhesive 31 and the fourth adhesive 34 have the same shape and size, the second adhesive 32 and the third adhesive 33 have the same shape and size, and the first auxiliary adhesive 35, the second auxiliary adhesive 36, the third auxiliary adhesive 37, and the fourth auxiliary adhesive 38 have the same shape and size. Therefore, when manufacturing adhesive parts, only three types of adhesive need to be manufactured, the first type is the first adhesive 31 (the fourth adhesive 34 is common to the first adhesive 31), the second type is the second adhesive 32 (the third adhesive 33 is common to the second adhesive 32), and the third type is the first auxiliary adhesive 35 (the second auxiliary adhesive 36, the third auxiliary adhesive 37, and the fourth auxiliary adhesive 38 are common to the first auxiliary adhesive 35). The types of adhesive parts that need to be produced during production are simple, and a closed rectangular frame is formed by combining the adhesive parts, which greatly reduces the production cost; and the edges of the above-mentioned adhesive and auxiliary adhesive are all straight, which is convenient to operate during bonding, and dust, water and other small debris are not easy to enter the bonding place, ensuring the waterproof and dustproof effect.

[0040] In actual operation, the structure of the first embodiment is not limited. At least one of the second auxiliary adhesive 36, the third auxiliary adhesive 37 and the fourth auxiliary adhesive 38 has a different shape from the first auxiliary adhesive 35. Figure 6 , Figure 6 The structure diagram of the combined adhesive member of the second embodiment of the present invention is shown. In the second embodiment, the first edge 311 of the first adhesive 31 forms an angle 314 with the first bottom edge 313, and the angle 314 is 60 degrees. The fifth edge 312 of the first adhesive 31 forms an angle 315 with the first bottom edge 313, and the angle 315 is 60 degrees. The fourth adhesive 34 also has a fourth bottom edge 343 adjacent to the fourth edge 341. The fourth edge 341 of the fourth adhesive 34 forms an angle 344 with the fourth bottom edge 343, and the angle 344 is 60 degrees. The eighth edge 342 of the fourth adhesive 34 forms an angle 345 with the fourth bottom edge 343, and the angle 345 is 80 degrees. In this embodiment, each auxiliary adhesive has a symmetrical structure, and specifically, each auxiliary adhesive can be designed symmetrically about the angular bisectors of its two auxiliary edges. Furthermore, the structure of the combined adhesive component at the second corner 26 and the third corner 27 of the corresponding frame 20 is the same as the structure at the corresponding first corner 25, and the structure at the corresponding fourth corner 28 is different from the structure at the corresponding first corner 25 due to different angles.

[0041] See also Figure 7 , Figure 7The structure diagram of the combined adhesive backing member described in the third embodiment of the present invention is shown. In the third embodiment, the first edge 311 of the first adhesive backing 31 forms an angle 314 with the first bottom edge 313, and the angle 314 is 60°. The fifth edge 312 of the first adhesive backing 31 forms an angle 315 with the first bottom edge 313, and the angle 315 is 70°. The fourth adhesive backing 34 also has a fourth bottom edge 343 adjacent to the fourth edge 341. The fourth edge 341 of the fourth adhesive backing 34 forms an angle 344 with the fourth bottom edge 343, and the angle 344 is 80°. The eighth edge 342 of the fourth adhesive backing 34 forms an angle 345 with the fourth bottom edge 343, and the angle 345 is 90°. Therefore, the adhesive backing members corresponding to each corner of the frame 20 are slightly different in structure.

[0042] In the second and third embodiments, the structure of the adhesive backing parts corresponding to a certain corner or several corners is different from that of other parts. The user can design the shape, angle, etc. of each adhesive backing part according to actual needs, without limitation thereto.

[0043] See also Figure 8 , Figure 8 The flowchart of the bonding method of the combined adhesive backing member of the present invention is shown. The adhesive backing member 30 at least includes a first adhesive backing member 31, a second adhesive backing member 32 and a first auxiliary adhesive backing member 35. The method includes the following steps:

[0044] Step A ( S11 ): affixing the first adhesive 31 to the first periphery 21 of the frame 20 , and affixing the second adhesive 32 to the second periphery 22 of the frame 20 ;

[0045] Step B ( S12 ): attaching the first auxiliary adhesive 35 to the first corner 25 of the frame 20 , wherein the first periphery 21 and the second periphery 22 are larger than the first corner 25 .

[0046] The first adhesive backing 31 has a first edge 311, and the second adhesive backing 32 has a second edge 321. The first edge 311 is straight; the second edge 321 is straight; the first auxiliary adhesive backing 35 has adjacent first auxiliary edge 351 and second auxiliary edge 352. When the bonding is completed, the first auxiliary edge 351 is aligned with the first edge 311, and the second auxiliary edge 352 is aligned with the second edge 321 to ensure the waterproof and dustproof effect.

[0047] Similarly, the third adhesive 33 is attached to the third periphery 23 of the frame 20, the fourth adhesive 34 is attached to the fourth periphery 24 of the frame 20, and then the second auxiliary adhesive 36, the third auxiliary adhesive 37 and the fourth auxiliary adhesive 38 are attached to the second corner 26, the third corner 27 and the fourth corner 28 of the frame 20. Finally, the display panel 10 is attached thereto.

[0048] In one embodiment, the adhesive member 30 may be first attached to the frame 20, and then the frame 20 with the adhesive member 30 attached thereto and the display panel 10 may be assembled. In actual operation, the adhesive member 30 may also be first attached to the display panel 10, and then the display panel 10 with the adhesive member 30 attached thereto and the frame 20 may be assembled. The user may perform the operation according to actual needs.

[0049] During the bonding process of the combined adhesive parts, the four adhesives corresponding to the four sides of the frame 20 are bonded first. Since the above four adhesives are simple long strip structures without L-shaped designs such as bending, there is no need to adjust the alignment of the bonding points during bonding, thus saving bonding time; then the four auxiliary adhesives corresponding to the four corners of the frame 20 are bonded. Since the edges of the above auxiliary adhesives are aligned with the edges of the adhesives and the edges are all straight, the tolerances during adhesive production and the offsets generated during bonding can be absorbed, thereby avoiding overlapping of adjacent adhesives or excessive gaps at the bonding points, thereby ensuring sealing and achieving better waterproof and dustproof effects.

[0050] In summary, the present invention provides a combined adhesive backing for electronic devices, which splits the existing integral adhesive backing in a rectangular frame structure into adhesive backing parts that can be combined with each other, avoiding the waste of raw materials caused by overall cutting, and greatly reducing the production cost; further, the edges corresponding to the adhesive backing and the auxiliary adhesive backing are straight lines, and dust, water and other small debris are not easily entered at the fitting points, ensuring the waterproof and dustproof effect, with a simple structure and easy use.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
