Abstract

Technical Field
[0001] This utility model relates to the field of electronic materials technology, and more specifically, to an insulating and conductive partitioned composite film for electronic products. Background Technology
[0002] The trend towards lightweight and thinner electronic products necessitates the reduction of the size and shape of electronic components. Various functional adhesive tapes, such as conductive tape, shielding tape, and insulating tape, are frequently used for connection during component assembly. However, in actual production, the relatively small contact area between conductive tape and electronic products can lead to edge lifting and detachment after application, resulting in weak adhesion. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, this utility model provides an insulating and conductive partitioned composite film for electronic products, which has the advantages of avoiding edge curling and delamination, and ensuring firm adhesion.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an insulating and conductive partition composite film for electronic products, comprising conductive adhesive tape, conductive foam being attached to the top of the conductive adhesive tape, an isolation layer being attached to the top of the conductive foam, a release film being attached to the top of the isolation layer, and a protective film being attached to the bottom of the conductive adhesive tape.
[0005] The first mounting groove is located in the middle of the conductive adhesive tape, and a first pressure plate is fixedly installed inside the first mounting groove.
[0006] An extension piece is fixedly installed at the right end of the protective film, and rectangular holes are opened in the middle of both the conductive foam and the insulating layer.
[0007] The first pressing tablet includes a flat sheet and an extension block, both of which are located in a first mounting groove, with the extension block located on the left and right sides of the flat sheet.
[0008] The technical effects of the above technical solution are as follows: conductive tape is used to bond and conduct electricity between electronic components; conductive foam is used for conduction and buffering; the isolation layer is used to separate areas between electronic components that do not need to be bonded; by installing the first pressure plate inside the first mounting groove, since the first pressure plate is located below the rectangular hole, the conductive tape located on both sides of the rectangular hole is pressed flat onto the electronic components by the extension block on the first pressure plate, so as to avoid the conductive tape in the connection edge area inside the rectangular hole from peeling or detaching after bonding, thus ensuring the firmness of bonding.
[0009] In a preferred embodiment of this invention, conductive adhesive is applied between the conductive tape and the conductive foam, and between the conductive foam and the insulating layer. Adhesive is applied between the insulating layer and the release film, and between the conductive tape and the protective film. The adhesive strength between the insulating layer and the release film is less than the adhesive strength between the conductive tape and the protective film, less than the adhesive strength between the conductive tape and the protective film, and less than the adhesive strength between the conductive foam and the insulating layer.
[0010] The technical effects of the above solution are as follows: By applying conductive adhesive, the conductive tape, conductive foam, and insulating layer are connected to ensure smooth conductivity after bonding. The different bonding strengths of the conductive tape, conductive foam, insulating layer, release film, and protective film ensure that the conductive tape, conductive foam, release film, and protective film remain connected when the insulating layer is removed, and also remain connected after the release film is removed.
[0011] As a preferred embodiment of this utility model, the end of the extension block away from the flat plate is inclined upward, and the total length and width of the flat plate and the extension block are greater than the length and width of the rectangular hole.
[0012] The technical effects of the above technical solution are as follows: by setting the first pressure plate, the first pressure plate can press the conductive tape tightly onto the electronic component, and ensure that the adhesive surface of the conductive tape located in the rectangular hole completely covers the electronic component.
[0013] As a preferred embodiment of this utility model, the projection of the rectangular hole in the horizontal direction is located within the flat plate.
[0014] The technical effects of the above solution are as follows: it ensures the positioning of the electronic component and the bonding area on the conductive tape when the conductive tape is pasted onto the electronic component.
[0015] As a preferred embodiment of this utility model, a second mounting groove is provided in the middle of the protective film and the extension piece, and a pry bar is fixedly installed in the inner cavity of the second mounting groove.
[0016] The technical effects of the above solution are as follows: the extension piece is supported by the warp piece, so that the extension piece will not swing as the product bends and sways.
[0017] As a preferred embodiment of this utility model, the warping piece is composed of a horizontal rectangular piece and a bent piece installed at the rear end of the rectangular piece and tilted downwards.
[0018] The technical effects of the above technical solution are as follows: By setting the bending piece, the entire bending piece can be tilted, thereby making the right end of the extension piece tilted downward and separated in the horizontal direction. After the conductive tape is pasted on the electronic component, the extension piece can be prevented from directly contacting other electronic components, so as to facilitate the removal of the extension piece.
[0019] As a preferred embodiment of this utility model, positioning holes are provided on the conductive tape, conductive foam, isolation layer, release film and protective film.
[0020] The technical effects of the above technical solution are as follows: by setting positioning holes for alignment with electronic components, it is convenient to align the product during pasting.
[0021] As a preferred embodiment of this utility model, the conductive adhesive tape has an avoidance groove at its right end.
[0022] The technical effects of the above solution are as follows: by setting the clearance groove, it is possible to prevent the conductive tape from pressing on other electronic components during the pasting process. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] like Figures 1 to 6 As shown, this utility model provides an insulating and conductive partition composite film for electronic products, including a conductive tape 1, a conductive foam 2 attached to the top of the conductive tape 1, an isolation layer 3 attached to the top of the conductive foam 2, a release film 4 attached to the top of the isolation layer 3, and a protective film 5 attached to the bottom of the conductive tape 1.
[0032] The first mounting groove 6 is located in the middle of the conductive tape 1, and the first pressure plate 7 is fixedly installed inside the first mounting groove 6.
[0033] An extension piece 12 is fixedly installed on the right end of the protective film 5, and rectangular holes 11 are opened in the middle of the conductive foam 2 and the isolation layer 3.
[0034] The first pressing plate 7 includes a flat plate 71 and an extension block 72. Both the flat plate 71 and the extension block 72 are located in the first mounting groove 6, and the extension block 72 is located on the left and right sides of the flat plate 71.
[0035] Conductive tape 1 is used for bonding and conducting electricity between electronic components, conductive foam 2 is used for conducting electricity and buffering, and isolation layer 3 is used to separate areas between electronic components that do not need to be bonded. By installing a first pressure plate 7 inside the first mounting groove 6, since the first pressure plate 7 is located below the rectangular hole 11, the extension block 72 on the first pressure plate 7 is used to press the conductive tape 1 located on both sides of the rectangular hole 11 onto the electronic components, so as to avoid the conductive tape 1 in the connection edge area inside the rectangular hole 11 from peeling or detaching after bonding, thus ensuring the firmness of bonding.
[0036] Conductive adhesive is applied between conductive tape 1 and conductive foam 2, and between conductive foam 2 and insulating layer 3. Adhesive is applied between insulating layer 3 and release film 4, and between conductive tape 1 and protective film 5. The bonding strength between insulating layer 3 and release film 4 is less than the bonding strength between conductive tape 1 and protective film 5, the bonding strength between conductive tape 1 and protective film 5 is less than the bonding strength between conductive foam 2 and insulating layer 3, and the bonding strength between conductive foam 2 and insulating layer 3 is less than the bonding strength between conductive tape 1 and conductive foam 2.
[0037] The conductive tape 1, conductive foam 2, and insulating layer 3 are connected by applying conductive adhesive to ensure smooth conductivity after bonding. The conductive tape 1, conductive foam 2, insulating layer 3, release film 4, and protective film 5 have different adhesive strengths, which ensures that the conductive tape 1, conductive foam 2, release film 4, and protective film 5 remain connected when the insulating layer 3 is removed, and the conductive tape 1, conductive foam 2, and protective film 5 remain connected after the release film 4 is removed.
[0038] The extension block 72 is inclined upward at the end away from the flat plate 71, and the total length and width of the flat plate 71 and the extension block 72 are greater than the length and width of the rectangular hole 11.
[0039] By setting the first pressure plate 7, the first pressure plate 7 can press the conductive tape 1 tightly onto the electronic component, and ensure that the adhesive surface of the conductive tape 1 located at the rectangular hole 11 completely covers the electronic component.
[0040] The projection of the rectangular hole 11 in the horizontal direction is located within the flat plate 71.
[0041] Ensure that the electronic component and the bonding area on the conductive tape 1 are positioned when the conductive tape 1 is pasted onto the electronic component.
[0042] The protective film 5 and the extension piece 12 are provided with a second mounting groove 8 in the middle, and a pry bar 9 is fixedly installed in the inner cavity of the second mounting groove 8.
[0043] The extension piece 12 is supported by the warp piece 9, so that the extension piece 12 will not swing as the product bends and sways.
[0044] Among them, the warp piece 9 is composed of a horizontal rectangular piece and a bent piece installed at the rear end of the rectangular piece that is tilted downwards.
[0045] By setting the bending piece, the entire lifting piece 9 can be tilted, thereby causing the right end of the extension piece 12 to be tilted downwards and separated in the horizontal direction. After the conductive tape 1 is pasted on the electronic component, the extension piece 12 can be prevented from directly contacting other electronic components, so as to make it easy to tear off the extension piece 12.
[0046] Positioning holes 10 are provided on the conductive tape 1, conductive foam 2, isolation layer 3, release film 4 and protective film 5.
[0047] The positioning hole 10 is provided for alignment with electronic components, making it convenient to align the product during pasting.
[0048] The conductive adhesive tape 1 has a clearance groove at its right end.
[0049] By setting clearance grooves, the conductive tape 1 can be prevented from pressing on other electronic components during the pasting process.
[0050] Working principle and usage process of this utility model:
[0051] When in use, first separate the isolation layer 3 from the conductive foam 2, then align the positioning hole 10 with the positioning shaft on the electronic component, and then stick the conductive tape 1 on the electronic component. When sticking, use the extension block 72 on the first pressure plate 7 to press the conductive tape 1 located on both sides of the rectangular hole 11 on the electronic component.
[0052] At this time, due to the presence of the pry bar 9, the right end of the extension piece 12 is at an angle to the electronic component, and the protective film 5 can be directly peeled off through the extension piece 12.
