Description

Technical Field

[0001] This invention relates to the field of conductive adhesive technology, and in particular to a three-dimensionally applicable, slip-aiding conductive adhesive. Background Technology

[0002] With the rapid development of the electronics and information industry, consumer electronics products such as laptops are continuously evolving towards thinner, lighter, more integrated, and higher-performance designs. This trend leads to increasingly compact internal spaces, placing extreme demands on the size, weight, and functional integration of internal components. The hinge, as a key structural component connecting the laptop's top cover (screen) and bottom cover (main unit), directly affects the overall opening and closing feel, long-term reliability, and electromagnetic interference (EMI) shielding effectiveness.

[0003] In traditional designs, friction, noise, and electromagnetic interference (EMI) in the hinge area are common challenges. To provide a smooth opening and closing experience, manufacturers typically use lubricants or low-friction pads on the contact surfaces of the hinge's moving parts. However, these methods carry risks such as lubricant contamination, dissipation, or pad displacement, affecting lifespan and stability. Simultaneously, to meet electromagnetic compatibility (EMC) standards, the densely packed signal cables inside the hinge area (such as display cables and camera cables) must undergo effective electromagnetic shielding (EMI). The metal casing of a laptop generates minute relative displacements and friction during opening and closing, which can easily lead to static electricity buildup or momentary interruptions in the grounding path, potentially interfering with the normal operation of internal precision circuits. Therefore, a continuous and reliable conductive connection is necessary to ensure EMC.

[0004] In existing technologies, the above problems are often addressed by separately attaching independent conductive tapes and slip pads. However, this discrete approach has significant drawbacks: First, it increases assembly steps and material costs, reducing production efficiency; second, precisely attaching two different functional tapes side-by-side in an extremely limited space requires very high alignment accuracy, is difficult to operate, and is prone to attachment deviations, affecting functional consistency; finally, the discrete tapes have poor adaptability to three-dimensional curved surfaces, and may experience problems such as lifting or detachment due to insufficient adhesion.

[0005] Therefore, there is an urgent need in this field for an innovative integrated solution that can combine conductivity and slip-aiding functions, possess ultra-thin and flexible characteristics, adapt to the complex three-dimensional structure of the pivot area, and meet the requirements of high-precision and high-efficiency mounting processes, so as to overcome the shortcomings of existing technologies. Summary of the Invention

[0006] To address the aforementioned technical problems, the present invention aims to provide a three-dimensionally mountable conductive adhesive patch for improving slip resistance. This invention integrates conductive and slip-resistant functions onto a single flexible protective film with pre-set bending lines, achieving both electromagnetic shielding and friction optimization in a single three-dimensional mounting process, significantly improving mounting accuracy, production efficiency, and reliability.

[0007] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: A three-dimensionally applicable conductive adhesive sticker for slipping, comprising: Flexible protective film; A conductive tape is applied to the first region of the flexible protective film; A slip-aid tape is applied to a second region of the flexible protective film that is distinct from the first region. The flexible protective film has a pre-set bending line, which is configured to allow the flexible protective film to bend along it during the application process, so that the conductive tape and the slip tape can adapt to and adhere to different three-dimensional surfaces of the component to be applied.

[0008] Furthermore, the preset bending line includes a first bending line and a second bending line. The first bending line is disposed in the first region, corresponding to the conductive tape. The second bending line is disposed between the first region and the second region.

[0009] Furthermore, the flexible protective film is a silicone protective film.

[0010] Furthermore, the flexible protective film is a long strip structure with a protruding area in the middle, the middle of the flexible protective film is the first area, and the left and right parts are the second areas respectively; the number of the slip-aiding tapes is two, which are symmetrically arranged on the second areas of the left and right parts of the flexible protective film respectively.

[0011] Furthermore, the flexible protective film has at least two sets of positioning holes, one set of which corresponds to the position of the conductive tape, and the other set of positioning holes corresponds to the position of the slip-aid tape.

[0012] Furthermore, the conductive tape is a conductive cloth tape with a surface impedance of less than or equal to 0.2Ω.

[0013] Furthermore, the thickness of the conductive tape is 0.015~0.03mm.

[0014] Furthermore, the slip-aid tape is a high molecular weight polyethylene film tape with a 180-degree peel strength greater than or equal to 450gf / 25mm.

[0015] Furthermore, the assembly formed by the flexible protective film, conductive tape, and slip-aid tape is disposed on the release film.

[0016] Furthermore, an auxiliary tape is provided on the outer side of the flexible protective film, which is then bonded to the release film to assist in fixing the assembly formed by the flexible protective film, conductive tape, and slip-aid tape.

[0017] The beneficial effects of this invention are as follows: (1) By integrating conductive tape and slip-aid tape onto a single flexible protective film, this invention achieves the integration of electromagnetic shielding and mechanical slip-aiding functions, creating a multifunctional composite component. This replaces the traditional approach of attaching two separate components, greatly saving the layout area in narrow spaces such as hinges, conforming to the trend of ultra-thin consumer electronics products, and providing greater flexibility for product structure design.

[0018] (2) This invention utilizes a flexible protective film as an integrated carrier to provide a stable relative positional relationship between the conductive tape and the slip-aid tape. During mounting, there is no need to perform multiple separate alignments on the two functional components. The positioning of the two areas can be completed simultaneously in one mounting, which significantly reduces the difficulty of operation and alignment error, improves production yield and assembly efficiency, and is conducive to large-scale manufacturing.

[0019] (3) The pre-set bending line in this invention enables the entire adhesive to be precisely bent according to the three-dimensional surface shape of the component to be attached, ensuring that the conductive tape and the slip tape can be attached to the surface with different spatial orientations at the same time, thus achieving one-time precise bonding of complex structural surfaces.

[0020] (4) Precise bonding guided by the pre-set bending line ensures full contact between each functional tape and the surface of the component, enabling the conductive tape to provide stable grounding and shielding effects, and avoiding problems such as lifting or falling off of the slip tape. This ensures that the slip tape effectively improves the friction characteristics of moving parts, and enhances the long-term reliability and durability of the adhesive products.

[0032] An auxiliary tape 5 is also provided on the outer side of the flexible protective film 1. The auxiliary tape 5 is long and strip-shaped.

[0033] Example like Figure 1 As shown, the three-dimensionally mountable conductive adhesive tape of this embodiment includes: Flexible protective film 1; Conductive tape 2 is disposed on the first region of the flexible protective film 1; The slip-aid tape 3 is disposed on the second region of the flexible protective film 1, which is different from the first region; The flexible protective film 1 has pre-set bending lines 12, which are configured to allow the flexible protective film 1 to bend during the application process, thereby enabling the conductive tape 2 and the slip-adhesive tape 3 to adapt to and adhere to different three-dimensional surfaces of the component to be applied. Specifically, the pre-set bending lines 12 include a first bending line 121 and a second bending line 122. The first bending line 121 is located in a first region, corresponding to the conductive tape 2; the second bending line 122 is located between the first region and the second region.

[0034] In this embodiment, the flexible protective film 1 is a silicone protective film, model CS7508L-25B, which includes a polyester film and a silicone layer. Under a test environment of 23±2℃ and 50%±5% relative humidity, the flexible protective film 1 has a 180° peel strength of 9.0±3.0gf / 25mm. The thickness of the flexible protective film 1 in this embodiment is 0.083mm.

[0035] The flexible protective film 1 is a long strip structure with a protruding area in the middle. The middle of the flexible protective film 1 is the first region, and the left and right parts are the second regions, respectively. Two slip-aiding tapes 3 are provided, symmetrically arranged on the left and right second regions of the flexible protective film 1, respectively. Corresponding to these two slip-aiding tapes 3, two second bending lines 122 are provided. The conductive tape 2 is specifically located in the upper part of the middle of the flexible protective film 1 (the upper part of the first region). More specifically, the upper edge of the conductive tape 2 is aligned with the upper edge of the protruding area in the middle of the flexible protective film 1. The first bending line 121 is located at the lower part of the protruding area, configured to allow a portion of the conductive tape 2 to bend along it.

[0036] The flexible protective film 1 has two sets of positioning holes 11. One set of positioning holes 11 includes two positioning holes 11, which correspond to the position of the conductive tape 2. The other set of positioning holes 11 includes two positioning holes 11, which are located on the left and right sides of the flexible protective film 1, respectively, and correspond to the positions of the two slip-aiding tapes 3.

[0037] Conductive tape 2 is a conductive cloth tape, model BYH-BL025BDJHG, which includes a black conductive cloth layer and a conductive adhesive layer disposed on one side of the conductive cloth layer. Its surface impedance is less than or equal to 0.1Ω, and its vertical impedance is less than or equal to 0.08Ω. The thickness of conductive tape 2 is preferably 0.025mm. The adhesive-free side of conductive tape 2 is adhered to the silicone layer of flexible protective film 1.

[0038] The slip-aid tape 3 is a high-molecular-weight polyethylene film tape, model CJ-UF50B, which includes a black polyethylene film layer and an adhesive layer, and its 180-degree peel strength is greater than or equal to 450gf / 25mm. In this embodiment, the slip-aid tape 3 has a thickness of 0.05mm. The non-adhesive side of the slip-aid tape 3 is adhered to the silicone layer of the flexible protective film 1.

[0039] An assembly consisting of a flexible protective film 1, a conductive tape 2, and a slip-aid tape 3 is disposed on a release film 4. The release film 4 is preferably a release film with raised dots. In this embodiment, the release film 4 is model KPZ5703. Specifically, the release film 4 covers the conductive adhesive layer of the conductive tape 2 and the adhesive layer of the slip-aid tape 3. The thickness of the release film 4 is 0.2 mm.

[0040] Each release film 4 integrates multiple sets of flexible protective films 1, conductive tapes 2, and slip-aiding tapes 3. An auxiliary tape 5 is also provided on the outer side of the flexible protective film 1; this auxiliary tape 5 is a long strip that is longitudinally attached to the horizontally arranged assembly of flexible protective films 1, conductive tapes 2, and slip-aiding tapes 3, and adheres to the release film 4 to assist in fixing the assembly formed by the flexible protective film 1, conductive tapes 2, and slip-aiding tapes 3. The assembly composed of the flexible protective film 1, conductive tapes 2, and slip-aiding tapes 3 is covered by the bottom protective adhesive surface of the release film 4 with raised dots and is further fixed by the upper auxiliary tape 5, forming a rigid whole that is easy to handle and transfer, and also prevents accidental bending or misalignment of the parts before application.

[0041] The process of applying this conductive adhesive pad to the hinge area of ​​a laptop is as follows: Remove a complete adhesive assembly (including flexible protective film 1, conductive tape 2 and slip-aiding tape 3) from the entire release film 4.

[0042] The adhesive assembly is moved horizontally to the target position above the laptop hinge area. Using a jig or vision positioning system, the conductive tape 2 is aligned with the target mounting position (metal frame) in the laptop hinge area through a set of positioning holes 11 on the flexible protective film 1 corresponding to the conductive tape 2. After accurate positioning, pressure is applied, and the tape is bent along the first bend line 121 to adaptively and firmly adhere the conductive tape 2 in the middle to the target mounting position, achieving grounding and electromagnetic shielding functions.

[0043] After the conductive tape 2 is applied, the flexible protective film 1 is bent downwards along the two pre-designed second bending lines 122. This bending action brings the lubricating tape 3 located in the second area on both sides of the flexible protective film 1 to the predetermined position. Then, it is aligned through another set of positioning holes 11, and after precise positioning again, the two lubricating tapes 3 are pressed and attached to the surface of the rotating shaft structure to provide it with lasting lubrication.

[0044] After ensuring that both conductive tape 2 and sliding tape 3 are firmly attached, peel off the flexible protective film 1. This completes the installation process. Conductive tape 2 and sliding tape 3 are precisely attached to two different surfaces that are perpendicular or at an angle in a single operation, adapting well to the three-dimensional structure of the hinge. After installation, sliding tape 3 provides a smooth, stable, and quiet opening and closing feel for the laptop, while conductive tape 2 establishes a continuous and stable grounding path, effectively dissipating static electricity, suppressing electromagnetic interference, and ensuring the safe operation of internal electronic components.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
