[0051] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] The present application will be further described in detail below with reference to the accompanying drawings.

[0053] This application discloses a method for manufacturing a foldable screen wrapping structure hinge steel sheet assembly.

[0054] like Figure 1 and Figure 8 As shown, the folding screen wrapping structure pivot steel sheet assembly includes: a first intermediate part 1, a second intermediate part 2, and a third intermediate part 3; the second intermediate part 2, the first intermediate part 1, and the third intermediate part 3 are sequentially attached and arranged.

[0055] One side of the second intermediate component 2 is folded outward and attached to the side of the first intermediate component 1 that is close to the third intermediate component 3.

[0056] This avoids the first intermediate component 1 from having its long edge away from the third intermediate component 3 directly rub against the components inside the folding screen when the folding screen rotates, thus preventing wear or damage to the first intermediate component 1 and effectively preventing abnormal noises during the folding process of the folding screen phone.

[0057] In this embodiment, the first intermediate component 1 is a steel plate, but it is not limited to steel plates.

[0058] In this embodiment, the second intermediate component 2 is polytetrafluoroethylene Mylar, where polytetrafluoroethylene is also known as Teflon or Teflon, but is not limited to polytetrafluoroethylene Mylar. The second intermediate component 2 can also be other materials such as polyurethane Mylar.

[0059] In this embodiment, the third intermediate component 3 is double-sided adhesive tape.

[0060] The second intermediate component 2 is also equipped with a positioning film 4 on the side opposite to the first intermediate component 1.

[0061] Specifically, the positioning film 4 is used to protect the outer surface of the second intermediate part 2 and to facilitate the installation and positioning of the folding screen wrapping structure pivot steel sheet assembly.

[0062] like Figure 1 and Figure 10 As shown, the manufacturing method of the foldable screen wrapping structure hinge steel sheet assembly includes the following steps:

[0063] S100, Die-cut the second intermediate assembly base film to obtain the second intermediate part 2;

[0064] S200, Die-cut the third intermediate assembly base film to obtain the third intermediate part 3;

[0065] S300: Etch the first intermediate substrate to obtain the first intermediate component 1;

[0066] S400, Perform surface treatment on the plurality of first intermediate components 1;

[0067] S500, assemble and bond multiple first intermediate components 1 and multiple second intermediate components 2, with each first intermediate component 1 and second intermediate component 2 configured in a one-to-one correspondence;

[0068] S600, assemble and attach a third intermediate component 3 to the side of each first intermediate component 1 facing away from the second intermediate component 2;

[0069] S700: The assembled first intermediate parts 1 are loaded into the bending fixture for folding and pressing.

[0070] The folding screen wrapping structure hinge steel sheet assembly includes a second intermediate component 2, a first intermediate component 1, and a third intermediate component 3, which are arranged sequentially. In the existing production process of assembling the folding screen wrapping structure hinge steel sheet assembly, one assembly must be completed before the next can be assembled. However, the manufacturing method of the folding screen wrapping structure hinge steel sheet assembly of this application, after processing and producing the first intermediate component 1, the second intermediate component 2, and the third intermediate component 3, can simultaneously produce and assemble multiple first intermediate components 1, multiple second intermediate components 2, and multiple third intermediate components 3, achieving simultaneous assembly of multiple folding screen wrapping structure hinge steel sheet assemblies. This solves the problem of low production efficiency in the existing production process for folding screen wrapping structure hinge steel sheet assemblies.

[0071] S100 is specifically explained as follows: the second intermediate assembly base film includes a second intermediate component support protective film 21, a second intermediate component assembly positioning protective base film, a positioning film base film, and a second intermediate component base film. The processing of the second intermediate component 2 involves die-cutting the second intermediate component base film into multiple second intermediate components 2.

[0072] like Figure 2 and Figure 3 As shown, S100 specifically includes the following steps:

[0073] S110, Stack and set the second intermediate component bottom protective film 21, assemble the second intermediate component positioning protective base film, positioning film base film and second intermediate component base film.

[0074] The second intermediate component support protective film 21, the second intermediate component assembly positioning protective base film, the positioning film base film, and the second intermediate component base film are respectively aligned with their respective central axes.

[0075] S120, punch and cut the protective film 21 of the second intermediate component support, cut multiple positioning protection cutting lines 23 on the positioning protective base film of the second intermediate component assembly, punch the shape of the positioning film base film and cut it to the positioning protective base film of the second intermediate component assembly to obtain multiple positioning films 4.

[0076] Specifically, the first mold is used for punching and cutting. First, the second intermediate component bottom protective film 21, the second intermediate component assembly positioning protective base film, the positioning film base film, and the second intermediate component base film are stacked on the worktable from bottom to top. The first mold opens a second positioning hole 24 on the combined film formed by the second intermediate component bottom protective film 21, the second intermediate component assembly positioning protective base film, the positioning film base film, and the second intermediate component base film. The second positioning hole 24 is opened at both ends of the combined film formed by the second intermediate component bottom protective film 21, the second intermediate component assembly positioning protective base film, the positioning film base film, and the second intermediate component base film. The setting of the second positioning hole 24 is used for subsequent assembly positioning.

[0077] After the second positioning hole 24 is opened, the waste generated from opening the second positioning hole 24 will be removed by suction or other discharge methods before proceeding with the subsequent operations.

[0078] Then the first mold punches and cuts down to the second intermediate part bottom protective film 21, cutting out the positioning protection cutting line 23.

[0079] The second intermediate component bottom protective film 21, the second intermediate component assembly positioning protective base film, the positioning film base film, and the second intermediate component base film are all rectangular in shape.

[0080] During the punching process of the first mold, five positioning protection cutting lines 23 are cut out by the first mold. The five positioning protection cutting lines 23 include one separation cutting line 231 and four area cutting lines 232. The separation cutting line 231 is located on the central axis of the second intermediate component assembly positioning protection base film, the positioning film base film and the second intermediate component base film, so as to facilitate the subsequent separation of the second intermediate component assembly positioning protection base film, the positioning film base film and the second intermediate component base film on both sides of the separation cutting line 231.

[0081] The region cutting line 232 includes a first region cutting line, a second region cutting line, a third region cutting line, and a fourth region cutting line. The first and second region cutting lines are close to the separation cutting line 231 and are located on opposite sides of the separation cutting line 231, with the distance from the first region cutting line to the separation cutting line 231 equal to the distance from the second region cutting line to the separation cutting line 231. The third and fourth region cutting lines are far from the separation cutting line 231 and are located on opposite sides of the separation cutting line 231. The third and fourth region cutting lines are located on the same side of the separation cutting line 231 as the first and second region cutting lines. A first Mylar region is formed between the first and third region cutting lines, and a second Mylar region is formed between the second and fourth region cutting lines.

[0082] After the first die-cutting is completed, process paper is attached to the side of the second intermediate component base film that is opposite to the positioning film base film. This is to protect the adhesiveness of the side of the second intermediate component base film that is opposite to the positioning film base film, so as to facilitate the subsequent assembly between the second intermediate component 2 and the first intermediate component 1.

[0083] After being cut by the area cutting line 232, the positioning film base film is cut into two identical shapes and sizes: a first positioning film base film and a second positioning film base film. Each of the first and second positioning film base films has a protruding tear-off point 41 at each opposite corner, allowing the user to easily tear the positioning film 4 from the surface of the second intermediate component 2. A marking layer is provided on the surface of the tear-off point 41, helping the user to pinpoint its location. The marking layer is a color with a significant contrast to the positioning film 4; in this embodiment, red Mylar is used as the marking layer.

[0084] After the first die-cutting is completed, the waste generated during the cutting process is removed to proceed to the next process.

[0085] The second mold is used to punch and cut downwards from the surface of the process paper to the second intermediate assembly positioning protective base film.

[0086] During the punching process of the positioning film base film, the second die punches around the outer periphery of both the first and second positioning film base films to punch out the shape of the positioning film base film. Then, it punches along the central axis of both the first and second positioning film base films.

[0087] The first and second positioning base films are finally punched into four positioning films 4 with the same shape and size by the second mold, and each positioning film 4 has a corresponding tear-off position 41.

[0088] After the positioning film 4 is finally punched out by the second mold, the overall size of the positioning film 4 is smaller than the second intermediate component bottom protection film 21 and the second intermediate component assembly positioning protection base film. The second positioning hole 24 is located at the two opposite ends of the second intermediate component bottom protection film 21 and the second intermediate component assembly positioning protection base film that protrude from the positioning film 4.

[0089] S130, punching the shape of the second intermediate part 2 and cutting it to the positioning film 4, the base film of the second intermediate part is punched into multiple second intermediate parts 2.

[0090] Specifically, a third mold is used to punch and cut downwards from the surface of the process paper to the positioning film 4.

[0091] In step S120, during the process of separating the cutting line 231 at the punching point, the first mold punches the second intermediate component base film into second intermediate component base film a and second intermediate component base film b. Therefore, during the punching process of the second intermediate component base film, the third mold punches around the outer periphery of the second intermediate component base film a and the second intermediate component base film b respectively to determine the shape of the second intermediate component 2. Then, punching is performed along the central axis of the second intermediate component base film a and the second intermediate component base film b respectively.

[0092] The second intermediate base film a and the second intermediate base film b are finally punched into four second intermediate parts 2 with the same shape and size through the third mold.

[0093] After the second intermediate part 2 is finally punched out by the third mold, the overall size of the outer frame of the second intermediate part 2 should be smaller than that of the positioning film 4.

[0094] S140, Form the outer frame of the second intermediate component assembly positioning protective base film.

[0095] Specifically, the fourth mold is used to punch downwards and cut through to the second intermediate part bottom protective film 21.

[0096] The fourth mold punches the outer edge of the second intermediate component assembly positioning protective base film. Under the punching of the fourth mold, the second intermediate component assembly positioning protective base film is punched out to form the second intermediate component assembly positioning protective film 22. The tear-off position 41 is set on the punched-out second intermediate component assembly positioning protective film 22.

[0097] S200 is specifically explained as follows: before assembling the folding screen wrapping structure hinge steel sheet assembly, the outer dimensions of the third intermediate part 3 need to be cut using a die-cutting machine according to actual production needs, so as to meet the size requirements of the first intermediate part 1.

[0098] The third intermediate combination base film includes the third intermediate component bottom protective film, the third intermediate component assembly positioning release base film, and the third intermediate component base film.

[0099] like Figure 4 and Figure 5 As shown, S200 specifically includes the following steps:

[0100] S210, Sequentially set the third intermediate component bottom protective film, the third intermediate component assembly positioning release base film, and the third intermediate component base film.

[0101] Specifically, the third intermediate component bottom protective film, the third intermediate component assembly positioning release film, and the third intermediate component base film are stacked on the workbench from bottom to top.

[0102] S220, the face paper is cut and cut to the third intermediate part assembly positioning release base film, and the shape of the third intermediate part 3 is die-cut out.

[0103] Specifically, the third intermediate component bottom protective film, the third intermediate component assembly positioning release film, and the third intermediate component base film are all rectangular in shape.

[0104] First, using the first mold, a third positioning hole 311 is formed on the combined film formed by the third intermediate component bottom protective film, the third intermediate component assembly positioning release film, and the third intermediate component base film. The third positioning hole 311 is formed at both ends of the combined film formed by the third intermediate component bottom protective film, the third intermediate component assembly positioning release film, and the third intermediate component base film. The position of the third positioning hole 311 corresponds to the position of the second positioning hole 24, which facilitates the subsequent assembly of the folding screen wrapping structure pivot steel sheet assembly. The waste generated from forming the third positioning hole 311 is removed by suction or other discharge methods before proceeding with subsequent operations.

[0105] Then, the outer frame cutting line of the first mold is used to cut the third intermediate part assembly positioning release base film, and the outer shape of the third intermediate part 3 is die-cut.

[0106] The third intermediate base film is eventually die-cut into multiple third intermediates 3, the number of which corresponds to the number of second intermediates 2.

[0107] In this embodiment, there are four third intermediate components 3 arranged in parallel. The arrangement of the four third intermediate components 3 is fixed. When the third intermediate components 3 are assembled with the second intermediate components 2, each third intermediate component 3 can be assembled at the edge of the corresponding second intermediate component 2.

[0108] S230, On the side of the third intermediate component 3 opposite to the third intermediate component assembly positioning release film, the adhesive face paper is attached.

[0109] Specifically, after the third intermediate part 3 is die-cut, an adhesive paper is attached to the side of the third intermediate part 3 that is away from the third intermediate part assembly positioning release film. The adhesive paper is designed to maintain and protect the adhesion of the third intermediate part base film that is away from the third intermediate part assembly positioning release film from the subsequent processing and assembly processes.

[0110] S240, the outer frame of the molded third intermediate component assembly positioning release base film.

[0111] Specifically, the second mold is used to punch and cut the third intermediate part to assemble and position the release liner.

[0112] The second mold punches the outer edge of the third intermediate component assembly positioning release film, and the third intermediate component assembly positioning release film is formed by the punching of the fourth mold.

[0113] The length of the third intermediate component assembly positioning release film is greater than the length of the third intermediate component 3, and the third positioning hole 311 is located on both sides of the third intermediate component 3 assembly positioning release film at a position that protrudes from the third intermediate component 3.

[0114] S300 is specifically explained as follows: The processing of the first intermediate part 1 requires the use of etching to prevent the edges of the processed first intermediate part 1 from curling or other phenomena.

[0115] like Figure 6 and Figure 7 As shown, S300 specifically includes the following steps:

[0116] S310, Etching and forming the first intermediate part 1.

[0117] Specifically, the first intermediate substrate is etched to form the shape of the first intermediate component 1.

[0118] S320, a protective film 11 is attached to the first intermediate component 1.

[0119] Specifically, after the first intermediate component 1 is etched and formed, a protective film 11 is attached to one side of the first intermediate component 1. The length of the protective film 11 is greater than the length of the first intermediate component 1, and first positioning holes 111 are respectively provided on both sides of the protective film 11 at positions protruding from the first intermediate component 1. The opening positions of the first positioning holes 111 correspond to the opening positions of the second positioning holes 24, so as to facilitate subsequent assembly between the first intermediate component 1 and the second intermediate component 2, and between the first intermediate component 1 and the third intermediate component 3.

[0120] like Figure 2 , Figure 4 , Figure 6 and Figure 9 As shown, S400 is specifically explained as follows: After the first intermediate component 1, the second intermediate component 2, the third intermediate component 3 and the positioning film 4 are all processed, the assembly process will be carried out.

[0121] Before assembling the first intermediate component 1 and the second intermediate component 2, a plasma cleaner is used to clean the side of the first intermediate component 1 that is away from the protective film 11, so as to improve the surface energy of the first intermediate component 1, enhance the surface adhesion of the first intermediate component 1, and improve the bonding strength between the first intermediate component 1 and the second intermediate component 2.

[0122] S500 is specifically explained as follows: The first intermediate component 1 and the second intermediate component 2 are assembled by an assembly fixture 5, wherein the assembly fixture 5 includes an assembly plate 51 and positioning pins 52. The assembly plate 51 is rectangular in shape, and multiple positioning pins 52 are provided, which are located at opposite ends of the same surface of the assembly plate 51.

[0123] When the first intermediate component 1 and the second intermediate component 2 are assembled, the first intermediate component 1 and the second intermediate component 2 are sequentially placed on the assembly fixture 5.

[0124] The protective film 11 is bonded to the surface of the assembly plate 51, and the side of the first intermediate component 1 facing away from the protective film 11 is bonded to the side of the second intermediate component 2 facing away from the positioning film 4, thus achieving assembly. During the installation of the first intermediate component 1 and the second intermediate component 2 onto the assembly plate 51, the first positioning holes 111 at both ends of the protective film 11 and the second positioning holes 24 at both ends of the second intermediate component assembly positioning protective base film cooperate with the positioning pins 52 on the assembly plate 51 to achieve the positioning assembly of the first intermediate component 1 and the second intermediate component 2.

[0125] Furthermore, since four second intermediate parts 2 are produced in one die-cutting process, the number of positioning pins 52 on the assembly corresponds to the one-time assembly of four second intermediate parts 2.

[0126] During the one-time assembly of the first intermediate component and the second intermediate component 2, four first intermediate components 1 are firstly installed on the assembly plate 51 in sequence. The first positioning holes 111 at both ends of each first intermediate component 1 are installed into the corresponding positioning pins 52. Then, since there are four second intermediate components 2 on one second intermediate component 2 facing away from the positioning film 4, it is only necessary to set each second positioning hole 24 on the second intermediate component 2 facing away from the positioning film 4 to the positioning pin 52 one by one to achieve the one-time installation of four second intermediate components 2 on the first intermediate component 1.

[0127] It should be noted that the side of the second intermediate component 2 facing away from the positioning film 4 and the side of the first intermediate component 1 facing away from the protective film 11 are both adhesive, and the first intermediate component 1 and the second intermediate component 2 are assembled by bonding.

[0128] S600 is specifically explained as follows: Before assembling the first intermediate component 1 and the third assembly, the protective film 11 adhering to the surface of the first intermediate component 1 must be removed first. Then, a plasma cleaner is used to clean the side of the first intermediate component 1 that is away from the second intermediate component 2, so as to increase the surface energy of the other side of the first intermediate component 1, enhance the surface adhesion of the first intermediate component 1, and improve the bonding strength between the first intermediate component 1 and the third intermediate component 3.

[0129] Furthermore, after the first intermediate component 1 is cleaned by a plasma cleaner and before the first intermediate component 1 is assembled with the third assembly, a primer is applied to the position where the first intermediate component 1 will be attached to the third intermediate component 3 to improve the bonding strength between the first intermediate component 1 and the third intermediate component 3.

[0130] When assembling the first intermediate component 1 and the third intermediate component 3, the first intermediate component 1 is first installed onto the assembly fixture 5 with the side of the first intermediate component 1 coated with primer facing upwards. Then, the adhesive paper attached to the surface of the third intermediate component 3 is peeled off, and the third intermediate component 3 is then attached to the surface of the first intermediate component 1 with the peeled-off side facing downwards. During the process of installing the first intermediate component 1 and the third intermediate component 3 onto the assembly plate 51, since the first intermediate component 1 is already attached to the second intermediate component 2, the second positioning holes 24 at both ends of the second intermediate component assembly positioning protective base film can cooperate with the positioning pins 52 on the assembly plate 51 to position the first intermediate component 1 on the assembly plate 51. At the same time, since four first intermediate components 1 and four second intermediate components 2 are assembled at once in step S220, four sets of assembled first intermediate components 1 and second intermediate components 2 are simultaneously adhered to one second intermediate component assembly positioning protective base film.

[0131] As shown in step S220, four third intermediate parts 3 are provided on one assembly positioning release film. Therefore, it is possible to install four third intermediate parts 3 onto four first intermediate parts 1 simultaneously. During the installation process, it is only necessary to set each third positioning hole 311 on the assembly positioning release film to correspond one-to-one with the positioning pin 52, so that four third intermediate parts 3 can be installed on the first intermediate parts 1 at one time.

[0132] S700 is specifically explained as follows: It should be noted that during the assembly of the first intermediate component 1, the second intermediate component 2 and the third intermediate component 3, the third intermediate component 3 is located at the edge of one long side of the first intermediate component 1 at the fitting position of the first intermediate component 1, and the second intermediate component 2 is positioned at the fitting position of the first intermediate component 1 such that the long side of the second intermediate component 2 with the tear-off position 41 is aligned with the long side of the first intermediate component 1 that is close to the third intermediate component 3, while the long side of the second intermediate component 2 that is away from the tear-off position 41 is exposed from the long side of the first intermediate component 1 that is away from the third intermediate component 3.

[0133] Before folding and pressing the assembled first intermediate part 1, the third intermediate part 3 assembly positioning release film on the surface of the third intermediate part 3 is removed.

[0134] Subsequently, as shown in step S120, the separation cutting line 231 divides the second intermediate component assembly positioning protective base film into two regions, and the separation cutting line 231 is located on the central axis of the second intermediate component assembly positioning protective base film, the positioning film base film, and the second intermediate component base film. The two regions separated by the separation cutting line 231 are named the first bending region and the second bending region, respectively. Cutting is then performed along the separation cutting line 231, at which point the separated first bending region and second bending region each have two assembled sets of folding screen wrapping structure pivot steel sheet assemblies.

[0135] The folding process of the hinge steel sheet assembly of the folding screen wrapping structure will now be explained using the first bending area as an example.

[0136] On the first bending area, two sets of folding screen wrapping structure pivot steel sheet assemblies are arranged in parallel, namely, two sets of first intermediate parts 1, two sets of second intermediate parts 2, and two sets of third intermediate parts 3 respectively. Each first intermediate part 1 is attached to the side of the third intermediate part 3 and is close to the other first intermediate part 1. The part of the second intermediate part 2 that protrudes from the edge of the first intermediate part 1 is away from the other first intermediate part 1.

[0137] The first bending area is placed into the bending fixture, which is provided with a bending positioning pin that mates with the second positioning hole 24. The second positioning hole 24 and the bending positioning pin are correspondingly set. The mate between the second positioning hole 24 and the bending positioning pin enables the bending fixture to limit the first bending area, thereby improving the stability of the first bending area on the bending fixture during subsequent bending processes.

[0138] The bending fixture includes a fixing part and a bending part. Two bending parts are provided, located on opposite sides of the fixing part. The bending parts are rotatably connected to the fixing part, and can be folded over the fixing part. The fixing part is provided with an array of suction holes. When the first bending area is placed on the bending fixture, the suction holes can attract and hold the first bending area, thereby stably fixing it on the bending fixture.

[0139] When the first bending area is set on the bending fixture, the second middle part protruding from the edge of the respective first middle part 1 on both sides of the first bending area is located on the bending part on both sides of the bending fixture, while the remaining parts of the two sets of folding screen wrapping structure pivot steel sheet assemblies are set on the fixing part.

[0140] When the bending fixture is activated, the two bending parts bend toward the side of the fixing part that has the first bending area. During the bending process, the second intermediate part 2 protruding from the first intermediate part 1 and abutting against each bending part will bend together with the bending part. Finally, the second intermediate part 2 protruding from the first intermediate part 1 will adhere to the side of the first intermediate part 1 that is adhered to by the bending part, thereby wrapping the edge of the long side of the first intermediate part 1 away from the third intermediate part 3 with the second intermediate part 2.

[0141] The second intermediate component 2 wraps around one long side of the first intermediate component 1 to prevent the edge of the long side of the first intermediate component 1 away from the third intermediate component 3 from directly rubbing against the internal components of the folding screen when the first intermediate component 1 rotates with the folding screen. This avoids wear or damage to the first intermediate component 1 and can also effectively prevent abnormal noises during the folding process of the folding screen phone.

[0142] After the second intermediate component 2 wraps around the edge of the long side of the first intermediate component 1 that is away from the third intermediate component 3, the second intermediate component assembly positioning protective base film attached to the second intermediate component 2 is removed.

[0143] The bending process in the second bending area is the same as that in the first bending area, and will not be described again here.

[0144] Furthermore, the bending fixture can be equipped with two sets of bending positioning pins to simultaneously install both the first bending area and the second bending area on the bending fixture, so that the bending fixture can simultaneously bend the folding screen wrapping structure pivot steel sheet assembly on the first bending area and the second bending area.

[0145] The bending fixture can simultaneously bend multiple folding screen wrapping structure pivot steel sheet components, greatly improving the efficiency of the manufacturing process.

[0146] The series of processes, including the processing of the first intermediate component 1, the second intermediate component 2, and the third intermediate component 3, as well as the assembly of the first intermediate component 1, the second intermediate component 2, and the third intermediate component 3, improve the tightness of the fit between the first intermediate component 1, the second intermediate component 2, and the third intermediate component 3, and effectively prevent the generation of wrinkles and bubbles during the lifting process, achieving a flat and bubble-free fit.

[0147] After the folding screen wrapping structure hinge steel sheet assembly is completed, a release film is attached to the side of the second intermediate part 2 that is opposite to the first intermediate part 1 for subsequent finished product inspection.

[0148] In summary, a method for manufacturing a foldable screen wrapping structure hinge steel sheet assembly includes: a second intermediate component 2, a first intermediate component 1, and a third intermediate component 3; the second intermediate component 2, the first intermediate component 1, and the third intermediate component 3 are sequentially attached and arranged.

[0149] A method for manufacturing the hinge steel sheet assembly of a foldable screen enclosure structure, including the following steps:

[0150] The second intermediate assembly base film is die-cut to obtain the second intermediate part 2;

[0151] The third intermediate assembly base film is die-cut to obtain the third intermediate part 3;

[0152] The first intermediate substrate is etched to obtain the first intermediate component 1;

[0153] Surface treatment is performed on multiple first intermediate parts 1;

[0154] Assemble and bond multiple first intermediate components 1 and multiple second intermediate components 2, with each first intermediate component 1 and second intermediate component 2 configured in a one-to-one correspondence;

[0155] A third intermediate component 3 is assembled and attached to the side of each first intermediate component 1 that is opposite to the second intermediate component 2;

[0156] The assembled first intermediate parts 1 are loaded into a bending fixture for folding and pressing.

[0157] The folding screen wrapping structure hinge steel sheet assembly includes a second intermediate component 2, a first intermediate component 1, and a third intermediate component 3, which are arranged sequentially. In the existing production process of assembling the folding screen wrapping structure hinge steel sheet assembly, one assembly must be completed before the next can be assembled. However, the manufacturing method of the folding screen wrapping structure hinge steel sheet assembly of this application, after processing and producing the first intermediate component 1, the second intermediate component 2, and the third intermediate component 3, can simultaneously produce and assemble multiple first intermediate components 1, multiple second intermediate components 2, and multiple third intermediate components 3, achieving simultaneous assembly of multiple folding screen wrapping structure hinge steel sheet assemblies. This solves the problem of low production efficiency in the existing production process for folding screen wrapping structure hinge steel sheet assemblies.
