Referring to fig. 2, fig. 2 is a schematic cross-sectional view of the electronic device of fig. 1 along a direction a-a.

The embodiment of the present application provides an electronic device 1000, which may include but is not limited to: a housing assembly 100, a display screen assembly 200, and a center frame 300. The two opposite side edges of the middle frame 300 are respectively fixedly connected with the housing assembly 100 and the display screen assembly 200, and can enclose an accommodating space for accommodating structures such as a motherboard, a battery, a camera assembly and the like.

Referring to fig. 3 and 4, fig. 3 is a schematic cross-sectional view of a housing assembly in an electronic device in the related art, and fig. 4 is a partially enlarged view of a region B in the housing assembly shown in fig. 3.

In the related art, the housing assembly 500 may include a light transmissive housing 501, a decorative film 502, and a painted trim 503. The transparent housing 501 is made of a transparent material, such as glass, polyester, etc. The light transmissive housing 501 includes oppositely disposed inner and

outer surfaces

5011 and 5012, wherein the inner surface 5011 is disposed toward the display screen assembly 200. The decorative film 502 and the painted edge 503 can be attached to the inner surface 5011, and since the light-transmitting housing 501 is made of a light-transmitting material, the user can observe the texture and color of the decorative film 502 and the painted edge 503 from the outer surface 5012, that is, the housing assembly 500 can display the texture and color of the decorative film 502 and the painted edge 503, so that the housing assembly 500 has a beautiful appearance.

Specifically, the inner surface 5011 of the light-transmitting housing 501 includes a first margin 5011a, and the decorative film 502 is attached to the inside of the painted margin 5011 a. It is understood that, in order to make the decorative film 502 completely located within the range of the inner surface 5011 during the installation process, the size of the decorative film 502 is significantly smaller than the size of the inner surface 5011, that is, the distance between the peripheral edge of the decorative film 502 and the edge of the light-transmitting housing 501 is greater than zero, in other words, there is white exposure on the inner surface 5011 of the light-transmitting housing 501. The painted patch 503 is disposed in the painted patch area 5011a to cooperate with the decorative film 502 to completely cover the inner surface 5011, thereby ensuring the consistency of the texture and color of the housing assembly 500, i.e. no exposed white area on the housing assembly 500. To ensure that the painted trims 503 can completely cover the painted trims 5011a (i.e., the exposed areas of the inner surface 5011 of the light-transmitting housing 501), the painted trims 503 need to cover part of the decorative film 502 in addition to the exposed areas, so as to avoid gaps between the painted trims 503 and the decorative film 502.

First, however, the white exposed area is usually only 0.30-0.50mm, while the painting margin 503 of the related art is usually applied by a full-surface painting scheme, and most of ink or even 90% of ink is wasted in the ineffective area. Secondly, the transparent housing 501 generally needs to be positioned and fixed in the process of spraying the edge repair 503, the jig base for fixing the transparent housing 501 generally takes the outer surface 5012 of the transparent housing 501 as a standard design, and due to processing errors, product deformation and other reasons, a gap is inevitably formed between the jig base and the transparent housing 501, so that in the process of spraying the edge repair 503, ink accumulation occurs in the gap area between the outer surface 5012 and the jig base, which causes an oil overflow phenomenon on the outer surface 5012 of the transparent housing 501, and the oil overflow is difficult to remove after pre-curing and baking. Moreover, the outer surface 5012 of the housing assembly 500 of the high-end device is treated by polarizer surface treatment (AG) and flash sand style, the outer surface 5012 of the transparent housing 501 is uneven, conventional polishing rods and polishing steel wire cloth cannot be used to remove oil spilled on the outer surface 5012, and the use of common dust-free cloth is very inefficient and increases the project cost.

Referring to fig. 5 to 8, fig. 5 is a schematic cross-sectional view of a housing assembly in the electronic device shown in fig. 2, fig. 6 is a partially enlarged view of a region C in the housing assembly shown in fig. 5, fig. 7 is an exploded schematic view of the housing assembly shown in fig. 5, and fig. 8 is an exploded schematic view of a modification of the housing assembly shown in fig. 7.

The present embodiments provide a new housing assembly 100 that may include, but is not limited to: the decoration film comprises a light-transmitting shell 10, a decoration film 20 and a first supplement edge 30, wherein the first supplement edge 30 is positioned at the peripheral edge of the decoration film 20 and is used for supplementing the decoration film 20. The light-transmissive housing 10 is made of a light-transmissive material, such as glass, polyester vinyl, or the like. The light transmissive housing 10 includes oppositely disposed inner and

outer surfaces

101 and 102, with the inner surface 101 disposed toward the display screen assembly 200. The decoration film 20 and the first supplement 30 can be located on the inner surface 101, and since the light-transmitting casing 10 is made of a light-transmitting material, the texture and color of the decoration film 20 and the first supplement 30 can be observed by a user from the outer surface 102 side, that is, the casing assembly 100 can present the texture and color of the decoration film 20 and the first supplement 30.

The light-transmitting housing 10 may have a 2D flat plate shape, a 2.5D arc shape, a 3D arc shape, etc., and is not particularly limited herein. Taking a 3D arc as an example, the inner surface 101 of the light-transmitting casing 10 is a substantially arc surface, and correspondingly, the combination shape of the decoration film 20 and the first supplementary edge 30 is a circular arc shape so as to fit the shape of the inner surface 101.

The light-transmissive housing 10 may include a first edge-filling region 1011, and the first edge-filling 30 is located within the first edge-filling region 1011. The first edge-filling region 1011 is substantially a hollow frame-shaped structure, and the shape of the first edge-filling region 30 corresponds to the shape of the first edge-filling region 1011. The decoration film 20 is located the internal surface 101 of printing opacity casing 10 and the peripheral edge of decoration film 20 is located the within range of first benefit limit 30, avoids having the clearance between decoration film 20 and the first benefit limit 30, improves decoration film 20 and the holistic uniformity of first benefit limit 30.

It should be noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

Optionally, the light-transmitting casing 10 may further include a first end surface 103 connecting the inner surface 101 and the outer surface 102, and the first end surface 103 is substantially a hollow frame-shaped structure. The first edge-supplementing region 1011 may be connected to the first end surface 103 (as shown in fig. 7) or may be spaced apart from the edge of the first end surface 103 (as shown in fig. 8), which is not particularly limited herein. In the present embodiment, the first edge-supplementing region 1011 is connected to the first end surface 103, so that the decoration film 20 can be matched with the first edge-supplementing region 30 to completely cover the inner surface 101 of the light-transmitting casing 10. When the housing assembly 100 is mated with the middle frame 300, the first complementary edge 30 of the housing assembly 100 may coincide with the middle frame 300, and the area of the housing assembly 100 away from the middle frame 300 presents the texture and color of the decorative film 20 and the first complementary edge 30.

In other embodiments, the first edge-supplementing region 1011 may be connected to the first end surface 103 or may be spaced apart from the edge of the first end surface 103, that is, an exposed white region exists between the first edge-supplementing region 30 and the first end surface 103. When the housing assembly 100 is engaged with the middle frame 300, the exposed white area between the first supplementary edge 30 and the first end surface 103 coincides with the middle frame 300, the edge of the first supplementary edge 30 of the housing assembly 100 is connected to the middle frame 300, and the area of the housing assembly 100 away from the middle frame 300 presents the texture and color of the decoration film 20 and the first supplementary edge 30.

In this embodiment, the first edge supplement 30 is located between the decoration film 20 and the light-transmitting housing 10, so that the connection between the decoration film 20 and the first edge supplement 21 is smooth and consistent. Specifically, the thickness of the decoration film 20 is between 0.13 mm and 0.15mm, and the thickness of the first patch 30 is between 4 μm and 8 μm, i.e., the thickness of the decoration film 20 is much greater than that of the first patch 30. When the first edge 30 is located between the decorative film 20 and the transparent casing 10, the decorative film 20 has almost no bending undulation, that is, the decorative film 20 can be better attached to the inner surface 101 of the transparent casing 10 and the first edge 30. In other embodiments, the decoration film 20 is located between the first patch 30 and the light-transmissive housing 10 for improving the conformance of the decoration film 20 and the first patch 30.

The decoration film 20 may be a film (i.e., a silver salt photosensitive film made of one of PC, PP, PET, or PVC materials), and has a thickness of 0.13-0.15mm, on one hand, the film is black, so as to absorb light emitted from the inside of the electronic device 1000, and prevent the case assembly 100 from having different surface brightness, or absorb light emitted from the outside into the inside of the electronic device 1000, thereby avoiding the oxidation of the light in the inner wall structure of the electronic device 1000, on the other hand, the film is soft and is easy to be attached to the inner surface 101 of the light-transmitting case 10, and in addition, the film can store a designated color and pattern, so that the case assembly 100 can present a designated color and pattern.

The first margin 30 may be disposed in the first margin area 1011 by pad printing. It will be appreciated that in order to provide a three-dimensional texture to the surface of the housing component 10, the texture of the first trim 30 should correspond to the texture of the decorative film 20; in order to make the color of the surface of the housing assembly 10 consistent, the color of the first supplement 30 is the same as the color of the decoration film 20.

In the present embodiment, the thickness of the first trims 30 is set to be 4 to 8 μm, so that the entire thickness of the decorative film 20 is hardly changed even if the decorative film 20 overlaps the first trims 30, and the conformity between the decorative film 20 and the first trims 30 is ensured.

Specifically, the first edge supplement 30 adopts the principle of gravure printing, the size, the thickness and the texture corresponding to the first edge supplement 30 are etched on a steel die in an exposure and development mode to form a concave plate surface, the prepared ink is scraped into the concave plate surface through a scraper, and the redundant ink is scraped into an ink cup so as to fully utilize the ink and reduce the waste of the ink. Generally, the scraper adopts a steel sheet with the thickness of 0.25-0.50mm, good elasticity and absolutely straight cutting edge, so as to fully ensure the thickness of ink in the intaglio surface and the recycling rate of the ink.

The ink remained in the intaglio surface is transferred to the first edge-mending area 1011 through the soft silicon rubber transfer printing head, so that the effect of spraying and mending the edges is achieved. It can be understood that, due to the pad printing mode, the size and the position of the first margin 30 are strictly controlled, and the problems of overflow and waste of the ink in the first margin 30 can be avoided. Moreover, due to the adoption of gravure printing, the texture of the first edge supplement 30 is consistent with the texture of the decorative film 20 and can be well butted, so that the consistency of the texture of the decorative film 20 and the texture of the first edge supplement 30 is improved. In addition, by means of pad printing, ink is prevented from spilling onto the outer surface 102 of the housing assembly 100.

Optionally, the distance between the peripheral edge of the decoration film 20 and the peripheral edge of the inner surface 101 is between 0.10 and 0.40mm, and specifically may be 0.1mm, 0.15mm, 0.20mm, 0.30mm, or 0.40mm, not to mention here, wherein the maximum distance between the peripheral edge of the decoration film 20 and the peripheral edge of the inner surface 101 is 0.40mm, and the minimum distance is 0.10 mm. The width of the first supplement 30 is between 0.45mm and 0.65mm, specifically 0.45mm, 0.50mm, 0.60mm or 0.65mm, which is not listed here, wherein the minimum width of the first supplement 30 is 0.45mm, and the maximum width of the first supplement 30 is 0.65 mm. That is, the minimum width of the first repair edge 30 is smaller than the maximum distance between the peripheral edge of the decoration film 20 and the peripheral edge of the inner surface 101, in other words, the peripheral edge of the decoration film 20 can cover a part of the first repair edge 30, thereby ensuring the reliability and consistency of the decoration film 20 and the first repair edge 30 as a whole.

Referring to fig. 9 to 11, fig. 9 is a schematic cross-sectional view of a housing assembly in an embodiment of the electronic device shown in fig. 2, fig. 10 is a partially enlarged view of a region D in the housing assembly shown in fig. 9, and fig. 11 is an exploded schematic view of the housing assembly shown in fig. 9.

In yet another embodiment, the housing assembly 10 may include a light transmissive housing 10, a decorative film 20, a first trim 30 and a second trim 40, wherein the first trim 30 is located at an outer peripheral edge of the decorative film 20 and the second trim 40 is located at an inner peripheral edge of the decorative film 20 for supplementing the decorative film 20. The light-transmissive housing 10 may include a first edge-filling region 1011 and a second edge-filling region 1012, the first edge-filling region 30 being located within the first edge-filling region 1011, and the second edge-filling region 40 being located within the second edge-filling region 1012. The first edge-filling region 1011 and the second edge-filling region 1012 are hollow frame-shaped structures, and correspondingly, the first edge-filling region 30 and the second edge-filling region 40 are hollow frame-shaped structures.

It can be understood that a camera hole may be formed on the housing assembly 100, the second edge-filling region 1012 surrounds the camera hole, and correspondingly, a corresponding first through hole 21 is formed on the decoration film 20, wherein an inner wall of the first through hole 21 is an inner peripheral edge of the decoration film 20; the light-transmitting casing 10 is provided with a second through hole 104, and an inner wall of the second through hole 104 is an inner peripheral edge of the inner surface 101 of the light-transmitting casing 10. The area of the first through hole 21 is slightly larger than that of the second through hole 104, so that the second fillet 40 is located in the second fillet area 1012. For another example, the housing assembly 100 may be provided with other holes, such as fingerprint identification holes, etc., which are not listed here. It is understood that the number of the second border area 1012 is at least one, such as one (camera hole), two (camera hole and fingerprint identification hole), etc., which are not listed here.

The decoration film 20 is located on the inner surface 101 of the light-transmitting shell 10, the outer peripheral edge of the decoration film 20 is located in the range of the first supplement edge 30, the inner peripheral edge of the decoration film 20 is located in the second supplement edge 40, a gap between the decoration film 20 and the first supplement edge 30 is avoided, and the overall consistency of the appearance of the shell assembly 100 is improved. The decoration film 20 is used for matching with the first edge supplement 30 and the second edge supplement 40 to improve the appearance reliability and consistency of the shell assembly 100, so that the whole color of the light-transmitting shell 10 corresponding to the decoration film 20, the first edge supplement 30 and the second edge supplement 40 is consistent. In the present embodiment, the thickness of the second bead 40 is between 4 to 8 μm, so that even if the decoration film 20 overlaps the second bead 40, the entire thickness of the decoration film 20 is hardly changed, thereby ensuring the uniformity of the decoration film 20, the first bead 30, and the second bead 40.

Similarly, the second bead 40 is produced in the same principle as the first bead 30, and the second bead 40 is produced in synchronization with the first bead 30. That is, the concave surface is formed by etching the sizes, thicknesses and textures corresponding to the first edge supplement 30 and the second edge supplement 40 on the steel die in an exposure and development manner. The ink remained in the intaglio surface is transferred to the positions of the first edge supplementing area 1011 and the second edge supplementing area 1012 through the soft silicon rubber transfer printing head, so that the effect of spraying and supplementing edges is achieved. As can be appreciated, since the positions of the first edge supplement 30 and the second edge supplement 40 are relatively fixed and the processes are completely the same, the first edge supplement 30 and the second edge supplement 40 can be performed synchronously, which not only saves ink, but also improves the processing efficiency.

It will be appreciated that in order to provide a three-dimensional texture to the surface of the housing component 10, the texture of the second fillet 40 is required to be consistent with the texture of the decorative film 20; in order to make the color of the surface of the housing assembly 10 consistent, the color of the second supplementary edge 40 is the same as the color of the decoration film 20.

Alternatively, the distance between the inner peripheral edge of the decoration film 20 and the inner peripheral edge of the inner surface 101 is between 0.10 and 0.40mm, and specifically may be 0.1mm, 0.15mm, 0.20mm, 0.30mm, or 0.40mm, not to mention here, wherein the maximum distance between the inner peripheral edge of the decoration film 20 and the inner peripheral edge of the inner surface 101 is 0.40mm, and the minimum distance is 0.10 mm. The width of the second supplement edge 40 is between 0.45mm and 0.65mm, specifically, 0.45mm, 0.50mm, 0.60mm or 0.65mm, which is not listed here, wherein the minimum width of the second supplement edge 40 is 0.45mm, and the maximum width of the second supplement edge 40 is 0.65 mm. That is, the minimum width of the second fillet 40 is smaller than the maximum distance between the inner peripheral edge of the decoration film 20 and the inner peripheral edge of the inner surface 101, in other words, the inner peripheral edge of the decoration film 20 can cover a part of the second fillet 40, thereby ensuring the reliability and consistency of the decoration film 20 and the second fillet 40 as a whole.

Referring to fig. 12, fig. 12 is a schematic cross-sectional view of a housing assembly in another embodiment of the electronic device shown in fig. 2.

In yet another embodiment, the housing assembly 100 may be made of a material that is not resistant to high temperature, such as a composite plastic board. The housing assembly 100 may include a light-transmissive housing 10, a decoration film 20, first and

second beads

30 and 40, and a plating layer 50. The light-transmissive housing 10 may include a first edge-filling region 1011, and the first edge-filling 30 is located within the first edge-filling region 1011. The plating layer 50 is located on the inner surface 101 and covers the first repair edge 30. The decoration film 20 is attached to one side of the electroplated layer 50, which is away from the inner surface 101, and the peripheral edge of the decoration film 20 is located in the range of the first repaired edge 30, so that a gap between the decoration film 20 and the first repaired edge 30 is avoided, and the overall consistency of the appearance of the shell assembly 100 is improved.

Wherein, because the housing assembly 100 is not resistant to high temperature, the ink used for the first edge supplement 30 is low temperature ink. Because the low-temperature ink is difficult to perform pre-curing treatment, the electroplated layer 50 covers the first repaired edge 30 and is used for protecting the first repaired edge 30 and preventing the first repaired edge 30 from falling off in the production process. The decoration film 20 is matched with the first repaired edge 30 to avoid a gap between the decoration film 20 and the first repaired edge 30, so that the reliability that the decoration film 20, the first repaired edge 30 and the second repaired edge 40 completely cover the inner surface 101 of the light-transmitting shell 10 is improved, and the whole color of the shell assembly 100 is consistent.

According to the housing assembly 100 provided by the embodiment of the application, the first supplement edge 30 is arranged in the first supplement edge area 1011, the decorative film 20 is positioned in the inner surface 101, the peripheral edge of the decorative film 20 is positioned in the range of the first supplement edge 30, and the decorative film 20 is used for being in full contact with the first supplement edge 30 and the decorative film 20, so that the appearance consistency of the corresponding area of the first supplement edge 30 and the decorative film 20 in the housing assembly 100 can be fully ensured, the use of ink can be reduced, and the waste of the ink can be reduced. In addition, the ink overflow can be avoided, which affects the production cost of the housing assembly 100.

Referring to fig. 5, 6 and 13, fig. 13 is a schematic flow chart illustrating a manufacturing method of a housing assembly according to an embodiment of the present disclosure.

The embodiment of the present application further provides a method for manufacturing the housing assembly 100, which may include the following steps:

step S01, the light-transmissive housing 10 is cleaned, wherein the inner surface 101 of the light-transmissive housing 10 includes a first edge-filling area 1011.

Specifically, the light-transmitting housing 10 is cleaned, the cleaning solution uses a weak base agent with PH8-10, and the dyne value of the inner surface 101 after cleaning is greater than 36, that is, the surface tension of the inner surface 101 is greater than 36mN/m, so that the first edge supplement 30 and the decoration film 20 can be tightly attached to the inner surface 101.

Referring to fig. 14, fig. 15 is a schematic flow chart illustrating a manufacturing method of a housing assembly according to another embodiment of the present application.

In step S02, the first margin 30 is pad-printed in the first margin region 1011.

Specifically, step S02 includes the steps of:

in step S21, a protective film is attached to the inner surface 101, and the protective film is disposed in the inner surface 101 and away from the first margin area 1011.

It should be understood that the pad printing first margin 30 is only within the range of the first margin area 1011, and in order to prevent dust falling and ink particles from contaminating the area of the inner surface 101 (i.e. the area where the decoration film 20 is fixed) except the first margin 30 during the pad printing process, a protection film for electrostatic adsorption process needs to be attached to the inner surface 101.

In step S22, the first pad printing is performed on the first edge-added region 1011, and a first edge-added region is generated by the pre-curing process.

Specifically, the size, thickness and texture corresponding to the first edge supplement 30 are etched on the first steel die in an exposure and development mode to form a first concave plate surface, the prepared ink is scraped into the first concave plate surface through a scraper, and the redundant ink is scraped into an ink cup, so that the ink is fully utilized, and the waste of the ink is reduced. The ink remaining in the first depressed face is first pad-printed by a soft silicone rubber pad, and pad-printed to the position of the first margin area 1011.

It can be understood that, in the process of the first pad printing, the pressing amount of the silicone rubber pad printing head is large, so that the ink at the arc-shaped position of the light-transmitting shell 10 is thin and the color is light, and the second pad printing is needed to improve the saturation of the color of the first trimming 30, so that the color of the first trimming 30 is the same as or consistent with the color of the decorative film 20, and further the consistency of the surface color of the shell assembly 100 is improved. In order to avoid the ink of the primary pad printing from falling off in the process of the secondary pad printing, the ink of the primary pad printing needs to be subjected to pre-curing treatment to generate a primary edge supplement. Specifically, the first transfer printed light-transmitting shell 10 is transferred to a baking finish tunnel furnace station to be heated for 4-6min, wherein the pre-curing temperature is 150-170 ℃. The pre-curing time is too short, the pre-curing effect is not obvious, and the processing time is wasted due to too long pre-curing time, so that the assembly line processing is not facilitated. The temperature of the pre-curing is lower than 150 ℃, the curing time of the ink is influenced, and the temperature of the pre-curing is higher than 170 ℃, so that energy is unnecessarily wasted.

And step S23, performing secondary pad printing on the surface of the primary edge repairing, and performing pre-curing treatment to generate a secondary edge repairing.

Specifically, the size, thickness and texture corresponding to the second edge supplement 40 are etched on the second steel die in an exposure and development mode to form a second concave plate surface, the prepared ink is scraped into the second concave plate surface through a scraper, and the redundant ink is scraped into an ink cup, so that the ink is fully utilized, and the waste of the ink is reduced. And the ink remained in the second intaglio surface is subjected to secondary transfer printing through the soft silicon rubber transfer printing head and is transferred to the surface of the primary edge repairing surface.

It can be understood that the secondary pad printing is to supplement ink to the area where the ink is thinner during the primary pad printing, so that the ink supplementation is not required to be performed according to the size of the first recessed plate, and if the second recessed plate is the same as the first recessed plate, the first edge supplement 30 is prone to generate the double-stripe phenomenon. Optionally, the second intaglio surface is internally shrunk by 0.05mm compared with the first intaglio surface in a single side, so that the secondary pad printing ink can completely fall in the range of the primary edge repairing, and the primary edge repairing is performed with ink repairing.

In order to avoid the ink of the secondary pad printing from falling off in the curing process, the ink of the secondary pad printing needs to be subjected to pre-curing treatment to generate secondary edge repairing. Specifically, the transparent shell 10 subjected to the secondary transfer printing is transferred to a baking varnish tunnel furnace station to be heated for 4-6min, wherein the pre-curing temperature is 150-170 ℃. Wherein, the pre-curing time is too short, the pre-curing effect is not ideal, and the pre-curing time is too long, which wastes the processing time and is not beneficial to the production line processing. If the pre-curing temperature is lower than 150 ℃, the curing time of the ink is influenced, and if the pre-curing temperature is higher than 170 ℃, the energy is unnecessarily wasted.

In step S24, the primary edge patch and the secondary edge patch are cured to generate the first edge patch 30.

Specifically, the light-transmitting housing 10 after the primary edge supplement and the secondary edge supplement is transferred to an electric oven for heat curing treatment. Wherein the temperature of the thermal curing treatment is 170-190 ℃, and the heating time is 35-45 min. It is understood that if the curing temperature is lower than 170 ℃, the curing time of the ink is prolonged, which affects the processing efficiency, and if the curing temperature is higher than 190 ℃, it is unnecessary and energy is wasted, and generally, the pre-curing temperature is preferably 180 ℃. The curing time is too short, the pre-curing effect is not ideal, and the processing time is wasted due to too long pre-curing time, which is not beneficial to the flow line processing.

Step S25, the protective film is removed.

In step S03, the decoration film 20 is disposed on the inner surface 101, wherein the outer peripheral edge of the decoration film 101 is located within the range of the first patch 21.

Referring to fig. 9, 10 and 15, fig. 15 is a schematic flow chart illustrating a manufacturing method of a housing assembly according to another embodiment of the present disclosure.

Another embodiment of the present application provides a method for manufacturing a housing assembly 100, which may include the following steps:

step S10, cleaning the light-transmissive housing 10, wherein the light-transmissive housing 10 includes an inner surface 101, and the inner surface 101 includes a first edge-filling region 1011 and a second edge-filling region 1012.

Referring to fig. 16, fig. 16 is a sub-flowchart of step S20 in the method for manufacturing the housing assembly shown in fig. 15.

In step S20, the first margin 30 is pad-printed in the first margin area 1011, and the second margin 40 is pad-printed in the second margin area 1012.

Specifically, step S20 includes the steps of:

in step S201, a protective film is attached to the inner surface 101, and the protective film is away from the first margin region 1011 and the second margin region 1012.

In step S202, a first pad printing is performed on the first margin area 1011 and the second margin area 1012, and a first margin is generated by a pre-curing process.

And step S203, performing secondary pad printing on the surface of the primary edge repairing, and generating a secondary edge repairing through pre-curing treatment.

Step S204, curing the primary edge patch and the secondary edge patch to generate a first edge patch 30 and a second edge patch 40.

In the process of primary pad printing, the pressing amount of the silicone rubber pad printing head is large, so that the ink at the arc-shaped position of the light-transmitting shell 10 is thin and the color is light, secondary pad printing is needed to improve the saturation of the colors of the first repaired edge 30 and the second repaired edge 40, the colors of the first repaired edge 30 and the second repaired edge 40 are the same as or consistent with the color of the decorative film 20, and the consistency of the surface color of the shell assembly 100 is further improved.

Step S205, the protective film is removed.

Step S30, disposing the decoration film 20 on the inner surface 101, wherein the outer peripheral edge of the decoration film 20 is located within the range of the first supplementary edge 30, the inner peripheral edge is located within the range of the second supplementary edge 40, and the decoration film 20 is used for cooperating with the first supplementary edge 30 and the second supplementary edge 40 to improve the uniformity and reliability of the whole casing assembly 100.
