Method for manufacturing a metal support base and metal support base

Abstract

The application discloses a manufacturing method of a metal supporting base and the metal supporting base. The manufacturing method comprises the following steps: arranging a plurality of metal strips in the same direction at intervals; filling an elastic adhesive layer between the adjacent metal strips to connect the adjacent metal strips, so as to obtain a metal supporting base semi-finished product; and trimming the metal supporting base semi-finished product, so as to obtain a metal supporting base finished product. The metal strips are arranged at intervals, and the adjacent metal strips are connected with each other through the elastic adhesive layer. The elastic adhesive layer between the metal strips can be elastically deformed under the action of an external force, so that the metal supporting base manufactured by the manufacturing method can be bent, and the bending capacity is relatively strong. Meanwhile, the hardness of the metal strips in the metal supporting base is not affected, so the metal strips are not easy to be damaged. On the other hand, the elastic adhesive layer can be elastically deformed under the action of the external force, that is, the elastic adhesive layer can keep or restore the original state without force, so that the structure of the metal supporting base is more stable.

Description

Technical Field

[0001] This invention relates to the field of foldable screen technology, and in particular to a method for manufacturing a metal support base and the metal support base itself. Background Technology

[0002] In recent years, foldable displays have gradually entered the public eye. Currently, the key module material for achieving foldable displays is the metal sheet. In existing technologies, holes are usually drilled in the bending area of ​​the metal sheet to form multiple hollow areas. The purpose of this is to relieve stress in the bending area and prevent the metal sheet from cracking during bending. However, this hole-drilling design can lead to insufficient hardness in the bending area of ​​the metal sheet, making it easily damaged. Furthermore, during the manufacturing process, the bending area of ​​the metal sheet is prone to deformation and misalignment, which can affect the overall assembly of the device. Summary of the Invention

[0006] Several metal strips are arranged at intervals along the same direction;

[0007] An elastic adhesive layer is filled between adjacent metal strips to connect them, resulting in a semi-finished metal support base.

[0008] The semi-finished metal support base is repaired to obtain the finished metal support base.

[0009] The method for manufacturing a metal support base according to a first aspect embodiment of the present invention has at least the following beneficial effects:

[0010] The manufacturing method of the metal support base according to this invention involves arranging metal strips at intervals, with adjacent metal strips connected to each other by an elastic adhesive layer. After finishing, the finished metal support base is obtained. The elastic adhesive layer between the metal strips can undergo elastic deformation under external force, allowing the metal support base manufactured by this method to be bent with strong bending ability without affecting the hardness of the metal strips, thus preventing damage to the metal strips. Furthermore, the elastic adhesive layer can undergo elastic deformation under external force, meaning it can maintain or return to its original shape when no force is applied, making the structure of the metal support base more stable.

[0011] According to a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, the upper surface of the elastic adhesive layer between the metal strips is lower than the upper surface of the metal strips.

[0012] According to a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, an elastic adhesive layer is filled between adjacent metal strips, comprising the following steps:

[0013] Fill the spaces between adjacent metal strips with a silica gel mixture;

[0014] Bake the silicone mixture between adjacent metal strips until the silicone mixture cures to form an elastic adhesive layer.

[0015] According to a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, the silicone mixture solution is formed by mixing silicone and a diluent in a 1:2 ratio.

[0016] According to some embodiments of the first aspect of the present invention, a method for manufacturing a metal support base, wherein metal strips are arranged at intervals to form a metal strip group; and a silica gel mixture is filled between adjacent metal strips, comprising the following steps:

[0017] Select an appropriate amount of silica gel mixture and place it on the metal strip assembly;

[0018] Use a scraper to fill the silica gel mixture between adjacent metal strips.

[0019] According to a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, a metal strip is fixed by a mold. The mold includes a PE protective film and a limiting frame formed by four limiting plates connected end to end in sequence. The PE protective film covers an opening of the limiting frame.

[0020] Arranging several metal strips at intervals along the same direction includes the following steps:

[0021] Arrange the metal strips sequentially within the limiting frame and attach them to the PE protective film.

[0022] According to a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, baking a silicone rubber mixture between adjacent metal strips includes the following steps:

[0023] Place the mold containing the metal strip and silicone mixture in the oven and bake.

[0024] According to a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, the process of trimming a semi-finished metal support base to obtain a finished metal support base includes the following steps:

[0025] Remove any excess elastic adhesive layer around the metal strip.

[0026] According to some embodiments of the second aspect of the present invention, a metal support base includes: a plurality of spaced metal strips and an elastic adhesive layer disposed between adjacent metal strips and adhered to the metal strips.

[0027] The metal support base according to some embodiments of the second aspect of the present invention has at least the following beneficial effects:

[0028] Metal strips are spaced apart, and adjacent strips are connected to each other by an elastic adhesive layer. This elastic adhesive layer can elastically deform under external force, allowing the metal support base manufactured in this way to bend with strong bending ability without affecting the rigidity of the metal strips, thus preventing damage. Furthermore, the elastic adhesive layer can elastically deform under external force, meaning it can maintain or return to its original shape when no force is applied, making the structure of the metal support base more stable.

[0029] According to some embodiments of the second aspect of the present invention, in a metal support base, the upper surface of the elastic adhesive layer is lower than the upper surface of the metal strip.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, left, right, front, back, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0040] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0041] The following is for reference only. Figure 1 To be continued Figure 3 This describes a method for manufacturing a metal support base according to a first aspect embodiment of the present invention.

[0042] Reference Figure 1 The manufacturing method of the metal support base according to the first aspect of the present invention includes the following steps:

[0043] S100: Several metal strips 100 are arranged at intervals along the same direction;

[0044] S200: An elastic adhesive layer 200 is filled between adjacent metal strips 100 to connect the adjacent metal strips 100, thus obtaining a semi-finished metal support base.

[0045] S300: Trim the semi-finished metal support base to obtain the finished metal support base.

[0046] The manufacturing method of the metal support base according to this invention involves arranging metal strips 100 at intervals, with adjacent metal strips 100 connected to each other by an elastic adhesive layer 200. After finishing, the finished metal support base is obtained. The elastic adhesive layer 200 between the metal strips 100 can undergo elastic deformation under external force, allowing the metal support base manufactured by this method to be bent with strong bending ability, without affecting the hardness of the metal strips 100, thus preventing damage to the metal strips 100. Furthermore, the elastic adhesive layer 200 can undergo elastic deformation under external force, meaning it can maintain or return to its original shape when no force is applied, making the structure of the metal support base more stable.

[0047] It should be noted that the metal strip 100 is a stainless steel strip 100, and commonly used domestic stainless steel materials can be selected, such as SUS430, SUS316, SUS301, etc. The thickness of the metal strip 100 is selected within the range of 0.1-0.2mm. Then, the stainless steel material is processed into the required strip shape through an etching process. Furthermore, when several metal strips 100 are arranged at intervals in the same direction, the several metal strips 100 are arranged along the width direction of the metal strip 100.

[0048] It should be noted that the distance between adjacent metal strips 100 is 0.45-0.55mm.

[0049] It should be noted that the elastic adhesive layer 200 can be double-sided tape, which is cut into strips and filled between adjacent metal strips 100, with both surfaces of the double-sided tape adhering to the metal strips 100 on both sides. Specifically, the thickness of the double-sided tape is equal to or greater than the distance between two adjacent metal strips 100. This arrangement ensures that the double-sided tape and the metal strips 100 are tightly bonded.

[0050] It should be noted that the elastic adhesive layer 200 can also be a material cured from a silicone mixture solution. Using a silicone mixture solution allows the cured silicone to adhere more firmly to the metal strip 100. This prevents the elastic adhesive layer 200 from separating from the metal strip 100 when the metal support base manufactured by the method of manufacturing the metal support base according to the first aspect of the present invention is bent, thus making the structure of the metal support base more stable.

[0051] In a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, the upper surface of the elastic adhesive layer 200 between the metal strips 100 is lower than the upper surface of the metal strips 100. Figure 3This arrangement allows adjacent metal strips 100 to move closer or further apart more easily, thereby making the metal support base manufactured by the method of manufacturing the metal support base according to the first aspect of the present invention easier to bend. Furthermore, this arrangement allows the metal support base manufactured by the method of manufacturing the metal support base according to the first aspect of the present invention to be wound up by a drive member of a roll, enabling the metal support base to be applied to a rollable display screen. It is understood that the lower surface of the elastic adhesive layer 200 between the metal strips 100 can also be recessed relative to the lower surface of the metal strips 100, which makes the metal support base manufactured by the method of manufacturing the metal support base according to the first aspect of the present invention easier to bend.

[0052] It should be noted that the thinnest thickness of the elastic adhesive layer 200 is 0.060-0.080 mm.

[0053] In a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, an elastic adhesive layer 200 is filled between adjacent metal strips 100, comprising the following steps:

[0054] Fill the space between adjacent metal strips 100 with the silica gel mixture solution;

[0055] Bake the silicone mixture between adjacent metal strips 100 until the silicone mixture cures to form an elastic adhesive layer 200.

[0056] It should be noted that the silica gel mixture is prepared by mixing silica gel and diluent in a 1:2 ratio. Specifically, the silica gel used in the manufacturing method of the metal support base in this embodiment of the invention is a type with good adhesion and tensile strength. The diluent is DOW SIL OS-20 diluent.

[0057] In a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, metal strips 100 are arranged at intervals to form a metal strip group; a silica gel mixture is filled between adjacent metal strips 100, comprising the following steps:

[0058] Select an appropriate amount of silica gel mixture and place it on the metal strip assembly;

[0059] Use a scraper to fill the silica gel mixture between adjacent metal strips 100.

[0060] It should be noted that the silica gel mixture has a certain viscosity, resulting in poor flowability. A scraper can be used to fill the gaps between adjacent metal strips 100. Specifically, an appropriate amount of silica gel mixture (selected according to the size of the metal strip 100) is selected with a glass rod and placed on the metal strip 100. The scraper is then used to fully fill the gaps between adjacent metal strips 100 with the silica gel mixture.

[0061] In the manufacturing method of the metal support base of some embodiments of the first aspect of the present invention, the metal strip 100 is fixed by a mold. The mold includes a PE protective film and a limiting frame 300 formed by four limiting plates 310 connected end to end in sequence. The PE protective film covers an opening of the limiting frame 300.

[0062] Arranging several metal strips 100 at intervals along the same direction includes the following steps:

[0063] Arrange the metal strips 100 sequentially within the limiting frame 300 and attach them to the PE protective film.

[0064] It should be noted that, in combination Figure 2 The length of the limiting frame 300 is set according to the length of the metal strip 100. The distance between the two inner walls of the limiting frame 300 along its length is equal to the length of the metal strip 100. This design allows the metal strip 100 to be engaged within the limiting frame 300. This prevents the metal strip 100 from shifting under external force during subsequent filling with the silica gel mixture, thus avoiding changes in the distance between adjacent metal strips 100. This ensures that the structure of the metal support base supported by the manufacturing method of the metal support base of this embodiment is more stable and conforms more closely to standards. The external forces acting on the metal strip 100 include, but are not limited to, the force exerted by the scraper on the metal strip 100 and the force exerted by the silica gel mixture on the metal strip 100. This design also prevents leakage of the silica gel mixture between adjacent metal strips 100.

[0065] It should be noted that the distance between the two inner walls of the limiting frame 300 along its length can be slightly greater than the length of the metal strip 100. This design makes it easier for the metal strip 100 to engage within the limiting frame 300. In this case, other fasteners are needed to secure the metal strip 100 to prevent it from shifting under external force.

[0066] It should be noted that attaching the metal strip 100 to the PE protective film serves to secure the metal strip 100. Double-sided tape or adhesive can be applied to the metal strip 100 before attaching it to the PE protective film. The PE protective film is made of a material that does not mix with silicone. After the silicone mixture has cured, the PE protective film can be removed, facilitating the demolding of the semi-finished metal support base.

[0067] In a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, baking a silica gel mixture between adjacent metal strips 100 includes the following steps:

[0068] Place the mold containing the metal strip 100 and the silicone mixture in the oven and bake.

[0069] It should be noted that baking in an oven can accelerate the curing of the silicone mixture, thereby improving the production efficiency of the metal support base.

[0070] It should be noted that a high-temperature gas spray gun can also be used to spray high-temperature gas directionally into the silica gel mixture solution.

[0071] In a method for manufacturing a metal support base according to some embodiments of the first aspect of the present invention, the process of trimming the semi-finished metal support base to obtain a finished metal support base includes the following steps:

[0072] Remove the excess elastic adhesive layer 200 around the metal strip 100.

[0073] It should be noted that because the silicone mixture has a certain degree of fluidity, it may flow between the metal strip 100 and the limiting frame during handling of the mold containing the metal strip 100 and the silicone mixture, or during baking. After the silicone mixture has cured, the excess elastic adhesive layer 200 around the metal strip 100 needs to be removed to ensure that the structure of the metal support base meets the processing requirements.

[0074] It should be noted that the finished metal support bases also need to be inspected, retaining those that meet the processing requirements and eliminating defective products.

[0075] The metal support base of some embodiments of the second aspect of the present invention is manufactured by the manufacturing method of the metal support base of the first aspect embodiment described above, and includes: a plurality of spaced metal strips 100 and an elastic adhesive layer 200 disposed between adjacent metal strips 100 and adhered to the metal strips 100.

[0076] Metal strips 100 are spaced apart, and adjacent metal strips 100 are connected to each other by an elastic adhesive layer 200. The elastic adhesive layer 200 between the metal strips 100 can undergo elastic deformation under external force, allowing the metal support base manufactured by this method to bend with strong bending ability without affecting the hardness of the metal strips 100, thus preventing damage to the metal strips 100. Furthermore, the elastic adhesive layer 200 can undergo elastic deformation under external force, meaning it can maintain or return to its original shape when no force is applied, making the structure of the metal support base more stable.

[0077] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
