[0002] In current mobile phone manufacturing processes, the screen and front casing are primarily assembled using adhesive bonding. Given that current screens (such as OLED (Organic Light-Emitting Diode) screens) require IP68 waterproofing (a rating of 6 for complete dust resistance and 8 for immersion), a 0.15mm wide adhesive sealant is needed around the joint between the screen and the front casing to prevent air leakage. During adhesive application, some excess adhesive needs to be applied to ensure a proper seal around the joint.

[0003] The current process involves applying adhesive to the screen, and then... Figure 1 The pressure-holding box shown provides all-around pressure holding, and the glue is applied around the joint before it dries. Because the existing pressure-holding box has multiple support feet A, which intermittently block the area around the screen, it makes glue application very inconvenient for workers, and the blocked areas are prone to being missed or not thoroughly cleaned. After the glue dries, the glue level is uneven throughout the ring, resulting in a high rate of appearance defects.

[0004] Therefore, the existing technology still needs to be improved and enhanced. Utility Model Content

[0025] This utility model provides a dual-purpose pressure-holding and adhesive-wiping box for mobile phone screens. To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the following detailed description, with reference to the accompanying drawings and embodiments, further illustrates the utility model. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this utility model.

[0026] Please also refer to Figures 2 to 8 This utility model provides a dual-purpose pressure-holding and adhesive-wiping box for mobile phone screens, including an upper box 10 and a bottom box 20. The screen and front shell assembly, after adhesive application, form a front cover plate 30. The front cover plate 30 is placed on the bottom box 20 with the screen (smooth surface) facing the bottom of the upper box 10. Support feet 11 on the left and right sides of the upper box 10 engage with the bottom box 20 to maintain pressure on the front cover plate 30. A portion of the screen edge where adhesive has overflowed is exposed on the edge of the upper box 10. The arched support feet 11 leave space on the other part of the screen edge for fingers to insert. This allows the entire screen edge where adhesive has overflowed to be visible without obstruction, facilitating adhesive removal by workers and improving the appearance quality of the front cover plate.

[0027] In this embodiment, as Figure 2 and Figure 3As shown, the upper box 10 includes a rectangular box body 12, with arched support feet 11 at the left and right ends of the box body 12; a plurality of first reinforcing ribs 13 are provided in the groove cavity inside the box body 12, and a support surface 14 for supporting the screen when pressing the screen is provided at the upper and lower ends of the back of the box body 12.

[0028] The four support feet 11 are respectively located at the upper left end, lower left end, upper right end, and lower right end of the housing 12, forming an "I" shape with the housing 12. This exposes the upper, lower, middle left, and middle right edges of the screen where adhesive has overflowed, facilitating subsequent adhesive removal. The arched design of the support feet 11 leaves space above the upper and lower ends of the left and right edges of the screen, allowing fingers to easily insert and remove adhesive. This ensures that the adhesive on the entire screen edge is visible and unobstructed, making it easy to wipe off.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the bottom of the support leg 11 is provided with a locking cavity 15 for locking and positioning. The buckle on the base box 20 passes through the locking cavity 15 and engages with the buckle on the cavity wall of the locking cavity 15. The top of the support leg 11 is provided with several second reinforcing ribs 16, which form four grooves aligned in pairs to increase the strength and rigidity of the support leg 11. The span S of the support leg 11 is preferably 24mm, and the arch height H is preferably 20mm; this can meet the space requirements for finger insertion; combined with the space on the base box 20, it further expands the space for wiping adhesive.

[0030] Multiple first reinforcing ribs 13 are distributed horizontally and vertically within the box body 12, dividing the recessed cavity into multiple compartments to improve the strength of the box body 12; this also eliminates the need for injection molding of the entire box body 12, saving material costs. The dimensions (length, height, and thickness) of each first reinforcing rib 13 are adjusted according to the dimensions of the box body.

[0031] To prevent the support surface 14 from causing wear and tear on the screen, a layer of foam adhesive or sponge pad can be glued to the support surface 14 to cushion and protect the screen.

[0032] like Figure 2 , Figure 6 and Figure 7 As shown, the base box 20 includes a base 21 and a pressure holding platform 22 disposed in the middle of the base 21, and the front cover plate 30 is placed on the pressure holding platform 22; the left and right ends of the base 21 are respectively provided with buckles 23 adapted to the support feet 11, and the buckles 23 pass through the engagement cavity 15 of the support feet 11 and engage with the buckle on the cavity wall of the engagement cavity 15.

[0033] Preferably, to prevent lateral wobbling during engagement, a snap hole 16 and a downwardly extending limiting hole 17 are provided within the engagement cavity 15; a limiting post 24 is arranged side-by-side on the side of the snap buckle 23; the size of the snap hole 16 matches the size of the snap buckle on the bottom box 20, and the size of the limiting hole 17 matches the size of the limiting post 24. Although the snap buckle 23 is higher than the limiting post 24, the limiting hole 17 extends downward. During engagement, the snap buckle 23 passes through the snap hole 16 and engages with the snap fastener on the wall of the engagement cavity 15; simultaneously, the limiting post 24 is inserted into the limiting hole 17, serving to limit and position the engagement.

[0034] Within the pressure holding platform 22, several corresponding shaped limiting ribs 25 are set at appropriate positions according to the layout of the electronic components at the bottom of the front cover 30. These ribs restrict the position of the front cover 30 and prevent movement during pressure holding. The shape and position of the limiting ribs 25 are adjusted accordingly for different layouts, also serving to prevent the front cover 30 from being placed backwards. A support ring 26 is set around the edge of the pressure holding platform 22 to support the front cover 30. Two limiting blocks 28 are set at intervals on the left and right sides of the support ring 26, respectively, to limit and support the battery compartment on the front cover 30.

[0035] The back of the base 21 is provided with several third reinforcing ribs 27, which are distributed horizontally and vertically to divide the groove cavity on the back of the base 21 into multiple grids to improve the strength of the base box 20; and it is not necessary to injection mold the entire base box 20, thus saving material costs.

[0036] It should be understood that the entire upper box 10 is preferably made of transparent plastic and molded as a single piece; the entire lower box 20 is preferably made of dark-colored (such as black) plastic and molded as a single piece; this facilitates observation of the pressure holding status of the front cover 30. Figure 8 As shown, the waistline 18 of the upper box 10 is recessed, exposing the middle of the left screen edge 32 and the middle of the right screen edge 31. The top and bottom edges of the upper box 10 are also recessed, exposing the upper screen edge 33 and the lower screen edge 34. The arched support feet 11 leave space on another part of the screen edge for fingers to insert. In this way, the entire screen edge where glue has overflowed can be seen without obstruction, making it convenient for workers to wipe off the glue and improving the appearance quality of the front cover.

[0037] In summary, the pressure-holding and adhesive-removing dual-purpose box for mobile phone screens provided by this utility model, by setting the upper box in an I-shape with a concave waistline to expose a portion of the screen edge where adhesive has overflowed, and by combining it with arched support feet to leave space for fingers to fit into the other portion of the screen edge, the entire screen edge where adhesive has overflowed can be seen without obstruction, making it convenient for workers to remove the adhesive and improving the appearance quality of the front cover.

[0038] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
