Description

[Technical Field]

[0001] TECHNICAL FIELD The embodiments herein relate to the technical field of intermediate frame manufacturing, and in particular to an intermediate frame for assembling a display module and a manufacturing method thereof. [Background technology]

[0002] Display modules, which are devices capable of displaying images, are widely used in various display devices. Display modules are composed of a cover glass, a display panel, a flexible circuit board, etc., and are relatively fragile and easily damaged by external impacts. Therefore, an intermediate frame must be attached to the display module to protect the display module.

[0003] Conventional resin intermediate frame manufacturing methods primarily use injection molding to produce them. The injection molding process requires separate molding for each required intermediate frame, meaning one mold can only produce one product model, resulting in long production cycles and high manufacturing costs. Furthermore, during the injection molding process, the injection mold must form a closed cavity, compressing the display module. The backlight side of the display module lacks rigidity, causing micro-deformation of the functional components in the compressed area, which alters the path of light emitted from the display module and causes uneven light scattering, resulting in differences in brightness between the compressed and uncompressed areas and visible dents on the display surface. This negatively impacts the display screen's display performance and user experience. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, the technical solutions of the present invention will be described through specific embodiments with reference to the drawings.

[0026] As shown in Figures 2 to 9, the display module assembly intermediate frame includes a first printed intermediate frame 1 printed on a display module 3 and a second printed intermediate frame 2 printed on an aircraft component, and the second printed intermediate frame 2 fits onto the first printed intermediate frame 1. A snap-in connection portion 11 is formed on the first printed intermediate frame 1, and a fitting portion 21 that engages with the snap-in connection portion 11 is formed on the second printed intermediate frame 2.

[0027] The size of the first printing intermediate frame 1 is designed based on the size of the actual display module 3, and similarly, the size of the second printing intermediate frame 2 is designed based on the size of the actual aircraft components. The first printing intermediate frame 1 and the second printing intermediate frame 2 are corresponding frame-shaped structures. When the display module 3 and the aircraft components are connected, the first printing intermediate frame 1 and the second printing intermediate frame 2 abut against each other. The snap-in connection part 11 and the fitting part 21 are used to increase the contact area between the first printing intermediate frame 1 and the second printing intermediate frame 2 and not only limit the position between the first printing intermediate frame 1 and the second printing intermediate frame 2 but also seal the frame interiors of the first printing intermediate frame 1 and the second printing intermediate frame 2.

[0028] The thicknesses of the first printing intermediate frame 1 and the second printing intermediate frame 2 are designed based on the actual structures of the display module 3 and the fuselage components so that the first printing intermediate frame 1 and the second printing intermediate frame 2 abut when the display module 3 and the fuselage components are combined.

[0029] The first and second printing intermediate frames 1 and 2 are both printed with a printing adhesive, which may be a heat-curing adhesive or a light-curing adhesive. The printing adhesive is designed based on the size of the first and second printing intermediate frames 1 and 2. The curing adhesive may be a heat-curing adhesive, such as epoxy adhesive 1318 or DP190, or a light-curing adhesive such as V-4260 or ZHU-2186.

[0030] In one embodiment (FIG. 9), the first printing intermediate frame 1 is assembled from a first intermediate frame body 101, a second intermediate frame body 102, and a third intermediate frame body 103, which are printed in that order. The second printing intermediate frame 2 is printed according to the structure of the first printing intermediate frame 1.

[0031] The first intermediate frame body 101 is printed on the substrate 31 according to the printing path, and the first intermediate frame body 101 surrounds the main body 32 of the display module 3, and the printing starting point of the first intermediate frame body 101 can be any point on the printing path.

[0032] After printing of the first intermediate frame body 101 is completed, printing of the second intermediate frame body 102 is carried out. The second intermediate frame body 102 is printed on the first intermediate frame body 101, and the printing material is recessed on both sides of the width of the second intermediate frame body 102, so that the second intermediate frame body 102 can cover both sides of the first intermediate frame body 101 and become integrated, and the second intermediate frame body 102 and the first intermediate frame body 101 can be tightly connected.

[0033] After printing of the second intermediate frame body 102 is completed, printing of the third intermediate frame body 103 is carried out. The third intermediate frame body 103 is printed between the first intermediate frame body 101 and the display module 3. When printing the third intermediate frame body 103, the printing material is recessed on both sides of the width of the third intermediate frame body 103, so that the printing material is filled between the first intermediate frame body 101 and the display module 3. At this time, the third intermediate frame body 103 tightly bonds the substrate 31, the second intermediate frame body 102, and the first intermediate frame body 101.

[0034] In another embodiment (FIGS. 7 and 8), the first printing intermediate frame 1 is assembled from a first intermediate frame body 101, a second intermediate frame body 102, a third intermediate frame body 103, and a fourth intermediate frame body 104, which are printed in that order. The second printing intermediate frame 2 is printed according to the structure of the second printing intermediate frame 2.

[0035] The first intermediate frame 101 is printed on the substrate 31 according to the printing path, and the first intermediate frame 101 surrounds the display module 3, and the printing starting point of the first intermediate frame 101 can be any point on the printing path.

[0036] After printing of the first intermediate frame body 101 is completed, printing of the second intermediate frame body 102 is carried out. The second intermediate frame body 102 is printed on the first intermediate frame body 101, and the printing material can be recessed on both sides of the width of the second intermediate frame body 102, so that the second intermediate frame body 102 covers both sides of the first intermediate frame body 101 and becomes integrated, thereby tightly bonding the second intermediate frame body 102 and the first intermediate frame body 101.

[0037] After printing of the second intermediate frame body 102 is completed, printing of the third intermediate frame body 103 is carried out. The third intermediate frame body 103 is printed between the first intermediate frame body 101 and the display module 3. When printing the third intermediate frame body 103, the printing material is recessed on both sides of the width of the third intermediate frame body 103, so that the printing material is filled between the first intermediate frame body 101 and the display module 3. At this time, the third intermediate frame body 103 tightly bonds the substrate 31, the second intermediate frame body 102, and the first intermediate frame body 101.

[0038] After printing of the third intermediate frame body 103 is completed, printing of the fourth intermediate frame body 104 is carried out. The fourth intermediate frame body 104 is printed in the gap between the third intermediate frame body 103 and the second intermediate frame body 102, connecting the third intermediate frame body 103 and the second intermediate frame body 102 through the fourth intermediate frame body 104 and preventing the joint structure between the third intermediate frame body 103 and the second intermediate frame body 102 from becoming too weak. [Example]

[0039] Example 1 As shown in FIG. 2, the first printing intermediate frame 1 and the second printing intermediate frame 2 both have flat surface structures, and the back surface of the first printing intermediate frame 1 is connected to the surface of the display module 3 by printing, and the back surface of the second printing intermediate frame 2 is connected to the surface of the fuselage component by printing.

[0040] The first and second printing frames 1 and 2 may be hollow rectangular frames of corresponding sizes, and the first and second printing frames 1 and 2 may have the same surface size. When the display module 3 and the body components are connected, the first and second printing frames 1 and 2 come into contact with each other, and the contact surfaces between the first and second printing frames 1 and 2 are processed to achieve a flatness of ±5 μm. When the display module 3 and the body components are connected, the first and second printing frames 1 and 2 come into close contact with each other, thereby achieving a waterproof seal for the body 32.

[0041] Example 1 is a preferred example of the present application.

[0042] Example 2 As shown in Figures 3 to 6, the snap-in connection portion 11 was a frame-shaped convex portion formed on the surface of the first printing intermediate frame 1, and the fitting portion 21 was a frame-shaped concave groove formed on the surface of the second printing intermediate frame 2.

[0043] The back surface of the first printing intermediate frame 1 is connected to the surface of the display module 3 by printing, and the back surface of the first printing intermediate frame 1 and the snap-in connection portion 11 are formed on opposite sides of the first printing intermediate frame 1, and the frame-shaped protrusion is a frame-shaped structure corresponding to the first printing intermediate frame 1 and is formed in the center of the surface of the first printing intermediate frame 1, and printing of the frame-shaped protrusion is carried out after printing of the main body part of the first printing intermediate frame 1 is completed.

[0044] The main body of the first printing intermediate frame 1 is a hollow rectangular structure, and the frame-shaped protrusion is also a corresponding hollow rectangular structure, and the height and thickness of the frame-shaped protrusion are both smaller than those of the main body of the first printing intermediate frame 1, so that the entire first printing intermediate frame 1 forms a convex structure.

[0045] The back surface of the second printing intermediate frame 2 is connected to the surface of the aircraft component by printing, and the back surface of the second printing intermediate frame 2 and the mating portion 21 are formed on corresponding two sides of the second printing intermediate frame 2, and the frame-shaped groove is a frame-shaped groove corresponding to the first printing intermediate frame 1 and is formed in the center of the surface of the second printing intermediate frame 2, and during the printing process of the main body portion of the second printing intermediate frame 2, a part of the main body portion of the second printing intermediate frame 2 is reserved and the required frame-shaped groove is formed.

[0046] The main body of the second printing intermediate frame 2 is a hollow rectangular structure, and the frame-shaped groove is a corresponding frame-shaped groove, and the height and thickness of the frame-shaped groove are both smaller than those of the main body of the second printing intermediate frame 2, so that the entire second printing intermediate frame 2 forms a concave structure.

[0047] When the first printing intermediate frame 1 and the second printing intermediate frame 2 abut against each other, the surfaces of the first printing intermediate frame 1 and the second printing intermediate frame 2 abut against each other, and the frame-shaped protrusions of the first printing intermediate frame 1 engage with the frame-shaped grooves of the second printing intermediate frame 2. Under the action of the frame-shaped protrusions and frame-shaped grooves of the frame-shaped structure, the multiple degrees of freedom of the first printing intermediate frame 1 and the second printing intermediate frame 2 are restricted, thereby restricting the positions of the first printing intermediate frame 1 and the second printing intermediate frame 2 and ensuring a stable connection between the first printing intermediate frame 1 and the second printing intermediate frame 2.

[0048] Example 3 The snap-in connection portion 11 is a frame-shaped recessed groove formed on the surface of the first printing intermediate frame 1 , and the fitting portion 21 is a frame-shaped protruding portion formed on the surface of the second printing intermediate frame 2 .

[0049] The back surface of the first printing intermediate frame 1 is connected to the surface of the display module 3 by printing, and the back surface of the first printing intermediate frame 1 and the snap-in connection parts 11 are formed on opposite sides of the first printing intermediate frame 1, and the frame-shaped groove is a frame-shaped groove corresponding to the first printing intermediate frame 1 and is formed in the center of the surface of the first printing intermediate frame 1, and during the printing process of the main body part of the first printing intermediate frame 1, a part of the main body part of the first printing intermediate frame 1 is reserved to form the required frame-shaped groove.

[0050] The main body of the first printing intermediate frame 1 is a hollow rectangular structure, and the frame-shaped groove is a corresponding frame-shaped groove, and the height and thickness of the frame-shaped groove are both smaller than those of the main body of the first printing intermediate frame 1, so that the entire first printing intermediate frame 1 forms a concave structure.

[0051] The back surface of the second printing intermediate frame 2 is connected to the surface of the aircraft component by printing, the back surface of the second printing intermediate frame 2 and the mating portion 21 are formed on corresponding two sides of the second printing intermediate frame 2, the frame-shaped concave groove is a frame-shaped groove corresponding to the first printing intermediate frame 1, and the frame-shaped convex portion is formed in the center of the surface of the second printing intermediate frame 2, and the frame-shaped convex portion is printed after printing of the main part of the second printing intermediate frame 1 is completed.

[0052] The main body of the second printing intermediate frame 2 is a hollow rectangular structure, and the frame-shaped convex portion is also a corresponding hollow rectangular structure, and the height and thickness of the frame-shaped convex portion are both smaller than those of the main body of the second printing intermediate frame 2, so that the entire second printing intermediate frame 1 forms a convex structure.

[0053] When the first printing intermediate frame 1 and the second printing intermediate frame 2 abut against each other, the surfaces of the first printing intermediate frame 1 and the second printing intermediate frame 2 abut against each other, and the frame-shaped protrusions of the second printing intermediate frame 2 engage with the frame-shaped grooves of the second printing intermediate frame 1. Under the action of the frame-shaped protrusions and frame-shaped grooves of the frame-shaped structure, the multiple degrees of freedom of the first printing intermediate frame 1 and the second printing intermediate frame 2 are restricted, thereby restricting the positions of the first printing intermediate frame 1 and the second printing intermediate frame 2 and ensuring a stable connection between the first printing intermediate frame 1 and the second printing intermediate frame 2.

[0054] Example 4 The snap-in connection portion 11 and the fitting portion 21 may have a corresponding triangular structure, semicircular structure, arc structure, or irregular structure, as long as the snap-in connection portion 11 and the fitting portion 21 as a whole have a frame-like structure and can realize the engagement between the first printing intermediate frame 1 and the second printing intermediate frame 2.

[0055] As shown in FIG. 1, a manufacturing method for a prefabricated intermediate frame of a display module, comprising the steps of: Step 102: printing and curing a first printing intermediate frame on the display module; Step 104: surface treating the printed first printing intermediate frame; Step 106 of printing and curing a second printed intermediate frame on the fuselage component; Step 108 of subjecting the printed second printing intermediate frame to a surface treatment; and Step 110: when assembling the display module and the fuselage component, the first printed intermediate frame and the second printed intermediate frame abut to form an assembled intermediate frame of the display module.

[0056] Before carrying out the method of the embodiment of this specification, a suitable adhesive is selected depending on the size of the resin intermediate frame required for printing, and a suitable printing needle is selected depending on the properties of the prepared adhesive and the intermediate frame size required for printing.

[0057] Examples of adhesives include, but are not limited to, heat-curing adhesives, epoxy adhesive 1318, DP190, etc., light-curing adhesives V-4260, ZHU-2186, etc., and examples of printing needles include, but are not limited to, ceramic needles and steel needles. The required printing needles are attached to the adhesive.

[0058] The display module 3 is placed on the 3D printer, the display module 3 is fixed by suction via the 3D printer, and the display module 3 is moved to the printing station of the 3D printer.

[0059] Before printing, the printing needles are wiped and the height of the substrate 31 of the display module 3 is scanned, and before the first printing intermediate frame 1 is printed, the height of the substrate 31 of the display module 3 on the corresponding printing path is scanned.

[0060] Import the printing path and printing parameters of the corresponding display module 3 into the 3D printer according to the display module 3. The printing path is designed according to the actual required structure of the first printing intermediate frame 1, and the printing parameters include a printing air pressure of 20 to 80 psi and a printing speed of 0.1 to 200 mm / s.

[0061] In one embodiment, the step 102 of printing and curing a first printed intermediate frame 1 on the display module comprises the following steps:

[0062] Step 1021: Obtain a first printing path of the first printing intermediate frame 1, and print a first intermediate frame body 101 on the display module according to the first printing path; The 3D printer can obtain the position of the display module on the vacuum suction table and the outer dimensions of the display module through a vision system. For example, the substrate 31 of the display module in this embodiment may be rectangular, with four rounded corners. The main body 32 is disposed in the center of the substrate 31 and also has a rectangular shape. In this embodiment, the horizontal distance from the edge of the substrate 31 to the edge of the main body 32 (i.e., S) may be 1000 microns, and the height of the main body 32 (i.e., H) may be 1500 microns.

[0063] The first printing path can be determined based on the external dimensions of the display module. Specifically, the first printing path is surrounded by the peripheral side of the main body 32 of the display module without adhering to the peripheral side. The first printing path is disposed above the substrate 31 of the display module, and surrounds the peripheral side of the main body 32 of the display module. However, there is a certain distance between the first printing path and the peripheral side of the main body 32, so that the first printing path is disposed so as not to adjoin the peripheral side of the main body 32. The printing start point of the first printing path overlaps with the printing end point of the first printing path, thereby closing the first printing path and allowing the printed first intermediate frame 101 to surround the main body 32. The printing start point of the first printing path can be any point on the first printing path.

[0064] The horizontal distance between the first printing path and the edge of the substrate 31 is S1, and the height from the first printing path to the top of the substrate 31 is H1. Since the value of S1 for the first printing path is fixed, the distance between the printed first intermediate frame 10 and the edge of the substrate 31 is fixed, thereby improving the aesthetics of the intermediate frame. The value of S1 may be calculated by subtracting 100 microns from the horizontal distance from the edge of the substrate 31 to the edge of the main body 32 (i.e., S) and dividing the result by two. In this embodiment, when S is 1000 microns, the value of S1 for the first printing path is 450 microns. In this embodiment, the value of H1 may be twice S1; for example, when S is 450 microns, H1 is 900 microns.

[0065] The 3D printer has a printing needle, and the 3D printer can move the printing needle along a first printing path (the bottom end of the printing needle is on the first printing path), and when the printing needle moves, the printing material for forming the intermediate frame can flow out from the bottom of the printing needle to form a first intermediate frame body 101.

[0066] The 3D printer is pre-installed with multiple printing needles with different inner diameters. Prior to printing the first intermediate frame 10, it is sufficient to select a printing needle with an appropriate inner diameter. For example, in this embodiment, a printing needle with an inner diameter of 900 microns is selected. The printing material can be recessed on both sides of the width of the first intermediate frame 101, allowing the first intermediate frame 101 to be tightly bonded to the edge of the substrate 31, while ensuring that the actual width of the first intermediate frame 101 exceeds 900 microns. Furthermore, in this embodiment, the printing needles move along a first printing path at a first moving speed. At this first moving speed, the height of the printed first intermediate frame 101 is slightly lower than the bottom end of the printing needles, preventing the printing needles from pressing against the first intermediate frame 101. The width of the first intermediate frame 101 is greater than the height of the first intermediate frame 101, improving the structural stability of the first intermediate frame 101. In this embodiment, the first moving speed may specifically be 10 mm / sec.

[0067] After the first printing path, printing needle, and first movement speed are all determined, the printing needle of the 3D printer moves along the first printing path at the first movement speed to print the first intermediate frame 101. After printing of the first intermediate frame 101 is completed, a first gap exists between the first intermediate frame 101 and the main body 32. By providing the first gap, it is possible to tightly bond the first intermediate frame 101 and the main body 32 thereafter.

[0068] Step 1023: Obtain a second printing path of the first printing intermediate frame 1, and print a second intermediate frame 102 on the display module according to the second printing path; The second printing path may be provided above the first printing path and parallel to the first printing path in the height direction. The printing start point of the second printing path and the printing end point of the second printing path are spaced apart, the second printing path is not closed, and one side of the second printing path corresponding to the main body 32 is open, and this side is used to connect the main body 32 to other components. The printing start point of the second printing path corresponds to a first end of the open side of the main body 32, and the printing end point of the second printing path corresponds to a second end of the open side of the main body 32.

[0069] The height from the second printing path to the top of the first intermediate frame 101 is H2. In this embodiment, the value of H2 can be the same as the value of H1, and if H1 is 900 microns, H2 may be 900 microns.

[0070] The printing needles of the second printing pass may be the same as those of the first printing pass, i.e., a printing needle with a diameter of 900 microns is directly used. The second moving speed may be the same as the first moving speed so that the height of the second intermediate frame 102 is slightly lower than the bottom end of the printing needles and the width of the final printed second intermediate frame 102 is greater than the height of the second intermediate frame 102.

[0071] After the second printing path, printing needle, and second movement speed are all determined, the printing needle is raised to a height of H2 and then moved to the printing start point of the second printing path. The printing needle of the 3D printer moves at the second movement speed along the printing start point of the second printing path to the printing end point of the second printing path, completing printing of the second intermediate frame 102. Because the printing material can be recessed on both sides of the width of the second intermediate frame 102, the second intermediate frame 102 can cover and integrate both sides of the first intermediate frame 101, thereby tightly bonding the second intermediate frame 102 and the first intermediate frame 101.

[0072] Before proceeding to step 1025, it is also necessary to determine whether the sum of H1 and H2 is greater than the height (i.e., H) of the body 32. In this embodiment, the sum of H1 and H2 is 1800 microns, which is greater than the height (1500 microns) of the body 32, so we can proceed directly to step 1025.

[0073] In another embodiment, if the sum of H1 and H2 is less than or equal to the height of the main body 32, step 1023 is repeated again, i.e., the printing needles are raised to a height of H2, and then the second intermediate frame 102 is reprinted. Next, it is determined whether the sum of H1 and the two H2 is greater than the height of the main body 32. If it is greater than the height of the main body 32, proceed to step 1025. If it is still less than the height of the main body 32, continue with step 1023, and then proceed to step 1025 after the latest second intermediate frame 102 is higher than the main body 32. In most cases, the sum of H1 and H2 is directly greater than the height of the main body 32, i.e., after performing step 1023 once, proceed directly to step 1025.

[0074] Step 1025: obtain a third printing path of the first printing intermediate frame according to the second printing path, and print a third intermediate frame body 103 on the display module according to the third printing path; The third printing path is provided above the main body 32 of the display module, and the third printing path and the second printing path are arranged horizontally side by side. The printing start point and printing end point of the third printing path are spaced apart, and the third printing path is also not closed to facilitate connection of the main body 32 with other components. The printing start point of the third printing path corresponds to a first end of the open side of the main body 32 (which may correspond to the printing start point of the second printing path), and the printing end point of the third printing path corresponds to a second end of the open side of the main body 32 (which may correspond to the printing end point of the second printing path).

[0075] The horizontal distance between the third printing path and the second printing path is S2. Specifically, S2 can be twice S1 plus 100 microns. If S1 is 450 microns, S2 is 1000 microns.

[0076] The printing needles of the third printing pass can be the same as those of the second printing pass, i.e., the printing needles with a diameter of 900 microns are directly used. The third moving speed needs to be faster than the second moving speed so that the height of the third intermediate frame 103 is slightly lower than the bottom ends of the printing needles.

[0077] After the third printing path, printing needle, and third movement speed are all determined, the printing needle is moved horizontally a distance S2 and then moved to the printing start point of the third printing path. The 3D printer's printing needle moves from the printing start point of the third printing path to the printing end point of the third printing path at the third movement speed, completing printing of the third intermediate frame 103. When printing the third intermediate frame 103, the printing material sinks into both sides of the third intermediate frame 103 in the width direction and fills the first gap. At this time, the third intermediate frame 103 tightly connects the main body 32, the second intermediate frame 102, and the first intermediate frame 101. The third intermediate frame 103 is specifically shown in FIG. 7.

[0078] Step 1027: The first intermediate frame 101, the second intermediate frame 102, and the third intermediate frame 103 are hardened to form the first printing intermediate frame 1.

[0079] After forming the specific structure of the first printing intermediate frame (i.e., the first intermediate frame body 101, the second intermediate frame body 102, and the third intermediate frame body 103), the first printing intermediate frame is hardened to obtain the final first printing intermediate frame.

[0080] The first printing intermediate frame 1 is cured depending on the properties of the selected adhesive, for example, a photo-curable adhesive can be cured by UV, and a thermo-curable adhesive can be cured by heating.

[0081] In this embodiment, the first printed intermediate frame is manufactured using a 3D printer, so the manufactured first printed intermediate frame is in close contact with the display module and does not deform the display module by compressing it during the manufacturing process of the first printed intermediate frame. Furthermore, even if the size of the display module changes, it is only necessary to replace the printing needles with the corresponding size, and there is no need to manufacture a mold tailored to the size of the display module, which reduces the manufacturing cost of the first printed intermediate frame.

[0082] After the printing path, printing needle, and moving speed of the first printing intermediate frame 1 are all determined, the printing needle of the 3D printer moves along the printing path at the set moving speed to print the first printing intermediate frame 1. After printing of the first printing intermediate frame 1 is completed, the first printing intermediate frame 1 surrounds the main body 32, and the inside of the first printing intermediate frame 1 is attached to the main body 32.

[0083] As shown in FIG. 10 , in another embodiment, the step 102 of printing and curing a first printing intermediate frame 1 on the display module includes the following steps: A step 1021' of obtaining a first printing path of the first printing intermediate frame and printing a first intermediate frame body 101 on a display module according to the first printing path; Step 1023': obtaining a second printing path of the first printing intermediate frame 1, and printing a second intermediate frame body 102 on the display module according to the second printing path; Step 1025': obtaining a third printing path of the first printing intermediate frame 1 according to the second printing path, and printing a third intermediate frame body 103 on the display module according to the third printing path; Step 1027' of obtaining a fourth printing path of the first printing intermediate frame 1 according to the third printing path, and printing a fourth intermediate frame body 104 on the display module according to the fourth printing path; and Step 1029′ of curing the first intermediate frame body 101, the second intermediate frame body 102, the third intermediate frame body 103, and the fourth intermediate frame body 104 to form the first printed intermediate frame 1.

[0084] Compared with the previous embodiment, this embodiment differs from step 1027 in steps 1027' and 1029'. That is, the first printing intermediate frame is formed by printing four intermediate frame bodies, while the former is formed by printing three intermediate frame bodies. Steps 1027' and 1029' will be described in detail below.

[0085] In step 1027', after printing the third intermediate frame body 103 is completed, the fourth intermediate frame body 104 needs to be printed on the display module. Before printing the fourth intermediate frame body 104, the fourth printing path needs to be determined first.

[0086] The fourth printing path is provided between the third printing path and the second printing path and can be arranged horizontally parallel to the third printing path. The printing start point and printing end point of the fourth printing path are separated, and the fourth printing path is also not closed to facilitate coupling of the main body 32 with other components. The printing start point of the fourth printing path can correspond to the printing start point of the third printing path, and the printing end point of the fourth printing path can correspond to the printing end point of the third printing path.

[0087] The horizontal distance between the fourth printing path and the third printing path is S3, which is half of S2. Since S2 is 1000 microns, S3 is 500 microns. The printing needles of the fourth printing path must be smaller than the printing needles of the third printing path; specifically, the inner diameter of the fourth printing needles may be 100 microns. The fourth moving speed must be faster than the third moving speed so that the height of the fourth intermediate frame 104 is slightly lower than the bottom ends of the printing needles.

[0088] After the fourth printing path, printing needle, and fourth movement speed are all determined, the printing needle is moved horizontally a distance S3 and then moved to the printing start point of the fourth printing path. The 3D printer's printing needle moves from the printing start point of the fourth printing path to the printing end point of the fourth printing path at the fourth movement speed, completing printing of the fourth intermediate frame 104. The fourth intermediate frame 104 is specifically shown in Figure 8. The fourth intermediate frame 104 is located in the gap between the third intermediate frame 103 and the second intermediate frame 102, connecting the third intermediate frame 103 and the second intermediate frame 102 via the fourth intermediate frame 104, preventing the connection structure between the third intermediate frame 103 and the second intermediate frame 102 from becoming too weak.

[0089] In step 1029', the first intermediate frame 101, the second intermediate frame 102, the third intermediate frame 103, and the fourth intermediate frame 104 are cured to form a first printing intermediate frame. After the specific structure of the first printing intermediate frame (i.e., the first intermediate frame 101, the second intermediate frame 102, the third intermediate frame 103, and the fourth intermediate frame 104) is formed, the first printing intermediate frame is cured to obtain the final intermediate frame.

[0090] The first printing intermediate frame 1 is cured depending on the properties of the selected adhesive, for example, a photo-curable adhesive can be cured by UV, and a thermo-curable adhesive can be cured by heating.

[0091] The difference from the previous embodiment is that this embodiment provides a fourth intermediate frame 104 between the third intermediate frame 103 and the second intermediate frame 102. The fourth intermediate frame 104 strengthens the connection between the third intermediate frame 103 and the second intermediate frame 102, making the structure of the final printed first printing intermediate frame more stable and strong.

[0092] Step 102 is The method further includes step 1011' of obtaining a scraping path based on the fourth printing path, and flattening the tops of the second intermediate frame body 102, the third intermediate frame body 103, and the fourth intermediate frame body 104 according to the scraping path. After the printing of the fourth intermediate frame body 104 is completed, the top of the first printing intermediate frame needs to be flattened, and before scraping, the scraping path needs to be determined first.

[0093] The scraping path is the same as the fourth printing path, the scraping start point of the scraping path is the same as the printing start point of the fourth printing path, and the scraping end point of the scraping path is the same as the printing end point of the fourth printing path. However, the scraping needle is different from the printing needle used to print the fourth intermediate frame 104, and specifically, the inner diameter of the scraping needle may be 2000 microns. The fifth moving speed is not particularly limited, but may be, for example, 18 mm / sec.

[0094] After the scraping path, scraping needle, and fifth movement speed are all determined, the scraping needle is moved to the scraping start point of the scraping path. The scraping needle of the 3D printer moves along the scraping path at the fifth movement speed from the scraping start point of the scraping path to the scraping end point of the scraping path, thereby flattening the tops of the second intermediate frame body 102, the third intermediate frame body 103, and the fourth intermediate frame body 104.

[0095] Furthermore, to obtain the scraping path, a topography scan is performed on the second intermediate frame 102, the third intermediate frame 103, and the fourth intermediate frame 104. The scraping path in this embodiment does not need to be exactly the same as the fourth printing path. After obtaining the topography of the second intermediate frame 102, the third intermediate frame 103, and the fourth intermediate frame 104, the scraping path can be adjusted up, down, left, and right based on the fourth printing path to improve the final scraping path, thereby improving the final scraping effect.

[0096] Step 102 of the embodiment herein comprises: It further includes a step 1020 of scanning and compensating the substrate 31 before performing step 1021 or step 1021'.

[0097] After the display module is placed on the vacuum suction table of the 3D printer, the vacuum suction table itself is not flat, so the substrate 31 may also be uneven. For example, if a certain point on the vacuum suction table rises upward by 20 microns, the corresponding point on the substrate 31 will also rise upward by 20 microns. If that point on the substrate 31 is on the printing path, the height of the intermediate frame body printed at that point will be 20 microns lower.

[0098] Therefore, before printing, the substrate 31 must first be scanned. If the substrate 31 is lower by x microns at a certain point, the position is compensated by -x microns. If the substrate 31 is higher by y microns at a certain point, the position is compensated by y microns. Specifically, for scan compensation, conventional techniques can be directly used.

[0099] In this case, if the printing needle moves to a certain location and that location is 10 microns lower, the printing needle will be adaptively adjusted downward by 10 microns. If the printing needle moves to a certain location and that location is 15 microns higher, the printing needle will be adaptively adjusted upward by 15 microns to make the height of the printed intermediate frame consistent and eliminate the situation where the height of some locations is too low, resulting in a better printing effect for the intermediate frame.

[0100] A specific height compensation method is to scan the height of the substrate 31 on the printing path with a height sensor to obtain the height of the substrate 31 on the printing path, and then raise or lower the height of the substrate 31 according to the printing speed of the 3D printer while the printing needle remains stationary, thereby achieving height compensation for the substrate 31.

[0101] When the recessed portion of the substrate 31 moves toward the printing needle, the substrate 31 is lifted appropriately under the action of the 3D printer, and the lifting distance corresponds to the dimensions of the recessed portion of the substrate 31, so that the recessed portion of the substrate 31 can be printed even when the printing needle is stationary. Similarly, when the protruding portion of the substrate 31 moves toward the printing needle, the substrate 31 is lowered appropriately under the action of the 3D printer, and the lowering distance corresponds to the dimensions of the protrusion of the substrate 31, so that the protruding portion of the substrate 31 can be printed even when the printing needle is stationary.

[0102] After the printing path, printing needle, and moving speed of the first printing intermediate frame 1 are all determined, the printing needle of the 3D printer moves along the printing path at the set moving speed to print the first printing intermediate frame 1. After printing of the first printing intermediate frame 1 is completed, the first printing intermediate frame 1 surrounds the main body 32, and the inside of the first printing intermediate frame 1 is attached to the main body 32.

[0103] In step 104 of performing surface treatment on the printed first printing intermediate frame 1, after printing of the first printing intermediate frame 1 is completed, the first printing intermediate frame 1 is surface treated by milling, laser or scraper methods so that the flatness of the first printing intermediate frame 1 reaches ±5 μm.

[0104] Step 106 of printing and curing a second printed intermediate frame on the airframe component includes the steps of: Step 1061: obtaining a printing path of the second printing intermediate frame 2 and printing the second printing intermediate frame 2 along the printing path in a layered printing manner; and Step 1063 of curing to form said second printing intermediate frame 2.

[0105] The size of the second printing intermediate frame 2 to be printed can be designed according to the structure of the first printing intermediate frame 1, and the printing path of the second printing intermediate frame 2 can be designed according to the corresponding machine body components, and the second printing intermediate frame 2 can perform one printing or multiple combined printings according to actual needs.

[0106] The aircraft component is placed on the 3D printer, the aircraft component is fixed by suction via the 3D printer, and the aircraft component is moved to the printing station of the 3D printer.

[0107] Before printing, the printing needles are wiped and the height of the fuselage components is scanned; before the second printing intermediate frame 2 is printed, the height of the fuselage components on the corresponding printing paths is scanned; and the printing paths and printing parameters of the fuselage components are imported into the 3D printer according to the fuselage components.

[0108] The printing path is designed according to the structure of the second printing intermediate frame 2 actually required, and the printing parameters include a printing air pressure of 20-80 psi and a printing speed of 0.1-200 mm / s.

[0109] The second printing intermediate frame 2 is cured depending on the properties of the selected adhesive, for example, a photo-curable adhesive can be cured by UV, and a thermo-curable adhesive can be cured by heating.

[0110] Step 106 in the embodiment of the present specification further includes scanning the height of the fuselage components before printing the second printing intermediate frame 2, and compensating the height of the fuselage components during the printing process according to the height scan data of the fuselage components.

[0111] The 3D printer prints the fuselage components according to the printing path and printing parameters to form the second printing intermediate frame 2, and after compensating for the height of the fuselage components, the 3D printer stably prints the second printing intermediate frame 2 on the fuselage components and conveniently hardens the printed first printing intermediate frame 1.

[0112] A specific height compensation method involves scanning the height of the fuselage components on the printing path with a height sensor to obtain the height of the fuselage components on the printing path, and then raising or lowering the height of the fuselage components according to the printing speed of the 3D printer while the printing needles remain stationary, thereby achieving height compensation for the fuselage components.

[0113] When the concave portion of the fuselage component is moved toward the printing needle, the fuselage component is lifted appropriately under the action of the 3D printer, the lifting distance corresponds to the dimensions of the concave portion of the fuselage component, so that the concave portion of the fuselage component can be printed even when the printing needle is stationary. Similarly, when the protruding portion of the fuselage component is moved toward the printing needle, the fuselage component is lowered appropriately under the action of the 3D printer, the lowering distance corresponds to the dimensions of the protruding portion of the fuselage component, so that the protruding portion of the fuselage component can be printed even when the printing needle is stationary.

[0114] In order for the 3D printer to print the first printing intermediate frame 1 and the second printing intermediate frame 2 uniformly, the starting point of the printing path of the first printing intermediate frame 1 coincides with the end point of the printing path of the first printing intermediate frame 1, and the starting point of the printing path of the second printing intermediate frame 2 overlaps with the end point of the printing path of the second printing intermediate frame 2.

[0115] In step 108 of performing surface treatment on the printed second printing intermediate frame 2, after the printing of the second printing intermediate frame 2 is completed, the second printing intermediate frame 2 is surface treated by milling, laser or scraper methods so that the flatness of the second printing intermediate frame 2 reaches ±5 μm.

[0116] After printing is completed, the first printing intermediate frame 1 and the second printing intermediate frame 2 are subjected to surface treatment by one, two or three of milling, scraping and laser processing.

[0117] When assembling the display module 3 and the fuselage components, step 110, in which the first printed intermediate frame 1 and the second printed intermediate frame 2 abut against each other to form an assembled intermediate frame of the display module, specifically involves applying a sealing adhesive to the frame-like structure defined by the first printed intermediate frame 1 and the second printed intermediate frame 2, applying the sealing adhesive to the display module 3 and the fuselage components, and then assembling them, with the first printed intermediate frame 1 and the second printed intermediate frame 2 abutting against each other.

[0118] A sealing adhesive is applied onto the frame structure defined by the first printing intermediate frame 1 and the second printing intermediate frame 2, and under the action of the sealing adhesive, the display module 3 is bonded to the fuselage components. When the display module 3 is bonded to the fuselage components, the first printing intermediate frame 1 and the second printing intermediate frame 2 are restricted and engaged, so that the first printing intermediate frame 1 and the second printing intermediate frame 2 form a first waterproof layer for the display module 3, and the adhesive layer forms a second waterproof layer for the display module 3, thereby providing better waterproof performance for the bond between the display module 3 and the fuselage components.

[0119] In actual use, if a resin intermediate frame with a height of 10~5000μm and a width of 10~5000μm needs to be printed, V-4260 light-curing adhesive is selected, prepared, and filled into a 3mL barrel and placed on the high-precision 3D printer.

[0120] A 400 μm ceramic printing needle was fabricated and attached to the 3D printer. The ceramic printing needle was then pointed downwards, and a barrel filled with photocurable adhesive was connected to the ceramic printing needle and used to supply the adhesive to the ceramic printing needle. An air cylinder was also attached to the barrel, and the photocurable adhesive was steadily ejected onto the ceramic printing needle under the action of air pressure.

[0121] The display module 3 is sucked and positioned on the 3D printer, and then moved to the printing station under the action of the 3D printer so that the printing needles correspond to the substrate 31 required for printing.

[0122] The needle is wiped, the substrate 31 of the display module 3 is scanned, and the scanned data is sent to the 3D printer, and the height compensation of the substrate 31 during the printing process is achieved by raising and lowering the printing needle or raising and lowering the substrate 31.

[0123] Import the printing path and printing parameters into the 3D printer according to the required first printing intermediate frame 1, and achieve printing of the first printing intermediate frame 1 under the action of the 3D printer, and complete UV curing.

[0124] The printed first printing intermediate frame 1 is milled so that the surface flatness of the first printing intermediate frame 1 reaches ±5 μm.

[0125] The fuselage component is sucked and positioned on the 3D printer, and the fuselage component is moved to the printing station under the action of the 3D printer so that the printing needles correspond to the fuselage component required for printing.

[0126] The needle is wiped, the fuselage component is scanned, and the scan data is sent to the 3D printer, and the height compensation of the fuselage component during the printing process is achieved by raising and lowering the printing needle or raising and lowering the fuselage component.

[0127] According to the required second printing intermediate frame 2, the printing path and printing parameters are imported into the 3D printer, and the printing of the second printing intermediate frame 2 is achieved under the action of the 3D printer, and UV curing is completed.

[0128] The printed second printing intermediate frame 2 is milled so that the surface flatness of the second printing intermediate frame 2 reaches ±5 μm.

[0129] After milling, the surface flatness of the first and second printing frames 1 and 2 reaches ±5 μm, which allows the first and second printing frames 1 and 2 to have better adhesion when they are in contact with each other. The frame-like structure of the first and second printing frames 1 and 2 provides better waterproofing and bonding stability.

[0130] The assembly between the display module 3 and the fuselage component is completed by applying a sealing adhesive to the display module 3 and the fuselage component and bonding them together.

[0131] An assembled intermediate frame for a display module is manufactured using a 3D printer according to a manufacturing method for an assembled intermediate frame for a display module, and a first printed intermediate frame 1 is printed on the substrate 31 of the display module 3, and a second printed intermediate frame 2 is printed on the fuselage component. When the display module 3 and the fuselage component are bonded with a sealing adhesive, the first printed intermediate frame 1 and the second printed intermediate frame 2 achieve a regulated engagement by the snap-in connection portion 11 and the fitting portion 21, and a waterproof structure for the display module 3 is realized under the action of the first printed intermediate frame 1 and the second printed intermediate frame 2.

[0132] The above examples are merely illustrative of preferred embodiments of the present invention and are not intended to limit the technical spirit and scope of the present invention. Various modifications and improvements that those skilled in the art can make to the technical means of the present invention without departing from the design concept of the present invention fall within the scope of protection of the present invention, and the technical contents that the present invention seeks to protect are all set forth in the claims.
