Description

Technical Field

[0001] This utility model relates to the field of jig technology, specifically to a graphene film assembly jig. Background Technology

[0002] Electronic devices, especially mobile communication and portable smart devices, are rapidly developing towards higher performance, thinner and lighter designs, greater flexibility, and higher reliability. This trend places extremely high demands on the comprehensive performance of key materials in these devices, particularly in terms of properties such as transparency, conductivity, efficient heat dissipation, and flexibility / foldability. Graphene, due to its excellent thermal conductivity, high mechanical strength, and good flexibility, is currently being used to replace traditional materials for functions such as heat conduction.

[0003] However, graphene films present numerous challenges in both production and shipping: 1. Even though graphene itself has high mechanical strength, it still needs to be protected during shipping to ensure product quality; 2. Because graphene film products are very small and light, especially when used in electronic devices with lightweight requirements, they are typically very small and light, making them difficult to handle during production, transportation, and assembly.

[0004] Therefore, there is an urgent need to develop a graphene film assembly fixture that facilitates the assembly of graphene film products. Utility Model Content

[0009] Optionally, several of the assembly grooves are arranged in a row; positioning posts are provided on the left side of the leftmost assembly groove and on the right side of the rightmost assembly groove.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or components / elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Figure 1 This is a schematic diagram of the structure of a graphene film assembly fixture provided in one embodiment of the present invention; Figure 2This is a cross-sectional view (AA) of a graphene film assembly fixture provided in one embodiment of this utility model. Figure 1-2 As shown, the graphene film assembly fixture includes: a fixture platform 1, a plurality of assembly grooves 2 disposed in the middle of the fixture platform 1, positioning posts 3 disposed on both sides of the assembly grooves 2, and a sealing layer 4 fitted on the positioning posts 3 and covering the assembly grooves 2; wherein, the sealing layer 4 is provided with holes that match the positioning posts 3.

[0020] According to one embodiment of the present invention, a plurality of the assembly grooves 2 are arranged in a row, and positioning posts 3 are provided on both sides of the uppermost and lowermost assembly grooves 2.

[0021] Specifically, Figure 1 and Figure 2 This is the first embodiment, with positioning posts 3 at the four corners for fitting the sealant layer 4 for assembly and adhesion. In use, a hollow flexible tube can be used to pick up the graphene film: one end of the hollow flexible tube is a suction cup. The operator squeezes the tube, places it on the graphene film, and then releases the tube; the suction cup then picks up the graphene film. After placing the graphene film on the assembly groove 2, the operator squeezes the hollow flexible tube to allow the graphene film to fall into the assembly groove 2. Next, the holes on the sealant layer 4 are fitted onto the matching positioning posts 3, thus covering the assembly groove 2 with the sealant layer 4. Finally, the entire sealant layer 4 is moved to the bottom, allowing the graphene film to adhere to the sealant layer 4.

[0022] It should be noted that the hollow flexible tube mentioned above can also be a solenoid valve vacuum tube, or it can be picked up by manual tweezers. These external operating tools are common knowledge, and since they are external operating tools, they are not within the scope of protection of this application, so they will not be described in detail.

[0023] According to the graphene film assembly fixture of this utility model, the graphene film can be placed in the fixture for assembly and bonding, ensuring that the graphene film is accurately positioned during assembly.

[0024] Figure 4 This is a schematic diagram of the structure of a graphene film assembly fixture provided in another embodiment of the present invention. According to one embodiment of the present invention, as shown below... Figure 4 As shown, several assembly grooves 2 are arranged in a row; positioning posts 3 are provided on the left side of the leftmost assembly groove 2 and on the right side of the rightmost assembly groove 2.

[0025] Specifically, Figure 4 This is the second embodiment. The graphene film assembly fixture in this embodiment is long and narrow. The operation method is the same, and the finished product can be selected according to the requirements.

[0026] It should be noted that the first and second embodiments of this application provide technical solutions arranged in a column and a row, respectively. Combining these two technical solutions yields an assembly groove 2 arranged in a row-column matrix. This assembly groove 2, arranged in a row-column matrix, is suitable for use in medium to large-scale automated production lines to improve assembly efficiency.

[0027] Figure 3 This is a schematic diagram of the structure of a graphene film assembly fixture provided in another embodiment of this utility model; Figure 5 This is a schematic diagram of the structure of a graphene film assembly fixture provided in another embodiment of the present invention; according to one embodiment of the present invention, such as Figure 3 , 5 As shown, each of the assembly grooves 2 has a positioning post 3 on both sides.

[0028] Specifically, Figure 3 This is the third embodiment. Figure 5 This is the fourth embodiment. Both of these embodiments share the characteristic that all assembly grooves 2 have positioning posts 3 on both sides. The advantage of the third embodiment is that multiple sealing layers 4 can be assembled with the internal graphene film within the same fixture, and then independently packaged and used after assembly. A common advantage of both the third and fourth embodiments is that if a single sealing layer 4 is used for overall assembly and bonding, more positioning posts 3 allow for more accurate positioning of the sealing layer 4 and better adhesion of the sealing layer 4 to the graphene film, avoiding the problem of "incomplete adhesion" where some parts are suspended.

[0029] According to one embodiment of the present invention, the sealing layer 4 is double-sided adhesive.

[0030] Specifically, when the graphene film needs to be used immediately for assembly, or when only short-distance or other low-risk transportation is required, the sealing layer 4 can be directly double-sided adhesive to reduce costs.

[0031] According to one embodiment of the present invention, the sealing layer 4 includes a protective film 41 disposed on the upper part and an adhesive layer 42 disposed on the lower part.

[0032] According to one embodiment of the present invention, the adhesive layer 42 is a double-sided adhesive or glue layer.

[0033] Specifically, when graphene film products need to be packaged and transported to prevent them from being scratched, the sealing layer 4 can be divided into an upper protective film 41 for scratch protection and a lower adhesive layer 42 for bonding the graphene film. Double-sided tape or adhesive layer is a low-cost adhesive that is easy to use in the production process, which is beneficial for bonding the protective film 41 to the graphene film.

[0034] According to one embodiment of the present invention, the protective film 41 is a polyethylene terephthalate film.

[0035] Specifically, polyethylene terephthalate (PET). PET material has good mechanical properties, is scratch and abrasion resistant, and is suitable for protecting the internal graphene film products during transportation.

[0036] The above embodiments are preferred implementations of this application. In addition, this application can be implemented in other ways. Any obvious substitutions without departing from the concept of this application are within the protection scope of this application.
