[0001] The utility model relates to the field of folding screen mobile phone maintenance fixture, in particular to a folding screen mobile phone back cover dismounting fixture. BACKGROUND

[0002] The folding screen mobile phone is a new type of mobile phone design, and its feature lies in that the screen can be folded inward or outward, so that the mobile phone can be freely converted between two states of small size and large size. In the folding screen mobile phone, the shell structure of the folding screen mobile phone comprises a middle frame and a back cover, the middle frame comprises an upper middle frame and a lower middle frame, the upper middle frame and the lower middle frame are connected through a rotating shaft and rotate around the rotating shaft to realize unfolding or folding; the back cover comprises an upper back cover and a lower back cover, and the upper and lower back covers are usually tightly attached to the upper and lower middle frames through foam glue.

[0003] At present, the main dismounting method of the back cover of the folding screen mobile phone is manual dismounting, that is, after the foam glue is heated and softened, the operator holds the mobile phone with one hand and dismounts the back cover with the other hand through a pry bar or a suction cup. This dismounting method is time-consuming and laborious, and the back cover and other parts are easily damaged. SUMMARY

[0004] Therefore, the utility model aims at overcoming the defects or deficiencies of the prior art, and provides a folding screen mobile phone back cover dismounting fixture, which can conveniently dismount the back cover of the folding screen mobile phone, is labor-saving, and is not easy to damage the product.

[0005] The utility model is realized through the following technical scheme: a folding screen mobile phone back cover dismounting fixture, including base, first suction cup, second suction cup, mounting plate and mobile phone profiling plate, the mounting plate sets up on the base, first suction cup and second suction cup set up on the mounting plate, the mounting plate is equipped with the through -hole in respectively corresponding the position of the air hole of first suction cup and second suction cup, with the air hole of first suction cup and second suction cup's gas pipe passes through the through -hole, the mobile phone profiling plate is located above first suction cup and second suction cup, and with base fixed connection, the mobile phone profiling plate is equipped with the through slot for placing folding screen mobile phone, be equipped with the boss for supporting the frame of folding screen mobile phone in the through slot, first suction cup and second suction cup set up in the through slot.

[0006] The folding screen mobile phone back cover dismounting jig provided by the utility model has the advantages that the through slot is arranged on the mobile phone profiling plate to place the folding screen mobile phone, the upper middle frame and the lower middle frame of the folding screen mobile phone are supported by the boss arranged in the through slot, when the first suction cup and the second suction cup are vacuumized, a low-pressure area is formed in the suction cup, the low-pressure area attracts the back cover to make the back cover adhere to the suction cup, the upper middle frame and the lower middle frame are kept unmoved by the support of the boss, the upper back cover and the lower back cover are separated from the upper middle frame and the lower middle frame respectively to form a gap under the downward suction force, after the vacuumization is stopped, the mobile phone is taken out, and the back cover can be slowly pulled open, time and labor are saved, and the product is not easily damaged.

[0007] Further, the suction surfaces of the first suction cup and the second suction cup are inwardly recessed to form suction cavities, and a plurality of protrusions are arranged in the suction cavities. In this way, the protrusions can form a closer contact between the suction cup and the back cover, reduce air leakage points, and increase the effective contact area of the suction cup and the back cover, thereby greatly enhancing the suction force of the suction cup and generating a greater friction force between the suction cup and the back cover to prevent relative sliding between the suction cup and the back cover and maintain a stable suction state.

[0008] Further, the first suction cup and the second suction cup are arranged along the length direction of the through slot in sequence, the first suction cup is flush with the second suction cup in the height direction, the surfaces of the two adjacent sides of the first suction cup and the second suction cup are flat surfaces that adhere to the middle part of the back cover of the folding screen mobile phone, and the surfaces of the remaining sides of the first suction cup and the second suction cup are curved surfaces that adhere to the edges of the back cover of the folding screen mobile phone. In this way, the sides of the first suction cup and the second suction cup respectively match the edge shapes of the upper back cover and the lower back cover, so that the first suction cup and the second suction cup are closely adhered to the upper back cover and the lower back cover respectively, the gap and air leakage phenomenon are reduced, and the suction force of the suction cup is enhanced.

[0009] Further, the surfaces of the two adjacent sides of the first suction cup and the second suction cup are lower than the surfaces of the remaining sides of the first suction cup and the second suction cup. In this way, when the folding screen mobile phone is placed in the through slot, the sides of the first suction cup and the second suction cup respectively contact the upper back cover and the lower back cover to form a closed space for subsequent effective suction.

[0010] Further, the through slot is further provided with a support beam for supporting the hinge shaft of the folding screen mobile phone, the support beam is located between the first suction cup and the second suction cup, and the top of the support beam is flush with the flat surface. In this way, when the back cover is suctioned, the support beam can support the hinge shaft of the folding screen mobile phone to avoid deformation or damage of the hinge shaft of the folding screen mobile phone under the suction force.

[0011] Further, the protrusions are lower than the plane. Thus, when vacuumizing, the first and second suction cups are deformed under the action of atmospheric pressure, so that the protrusions are closely attached to the surface of the back cover, thereby enhancing the adsorption force of the suction cups and maintaining a stable adsorption state. After stopping vacuumizing, the first and second suction cups return to their original shape under the action of atmospheric pressure, so that the protrusions are separated from the surface of the back cover, thereby facilitating the removal of the mobile phone from the mobile phone profiling plate.

[0012] Further, the first suction cup is further provided with a second cavity for accommodating the camera of the foldable-screen mobile phone, and the second cavity is arranged in the adsorption cavity. Thus, when the first suction cup is vacuumized, the camera of the foldable-screen mobile phone can be protected through the second cavity, so as to avoid affecting or damaging the camera.

[0013] Further, the protrusions are rectangular, and the protrusions are arranged in a matrix in the adsorption cavity. Thus, the design of the rectangular protrusions can increase the contact area with the back cover, and the matrix arrangement of the rectangular protrusions can make the rectangular protrusions uniformly attached to the surface of the back cover, so that a uniform friction force is generated between the suction cup and the back cover, thereby ensuring a stable adsorption state between the suction cup and the back cover.

[0014] Further, the first and second suction cups are both silica gel profiling suction cups. Thus, the silica gel profiling suction cup can be firmly adsorbed on the smooth surface of the back cover of the foldable-screen mobile phone under vacuum, and in addition, the silica gel material is soft and wear-resistant, so that the silica gel profiling suction cup can avoid causing scratches or damage to the contact surface when adsorbing the back cover of the foldable-screen mobile phone.

[0015] Further, the mobile phone profiling plate is detachably arranged on the base, and the mobile phone profiling plate is further provided with a hand holding opening, and the hand holding opening is arranged on both sides of the through slot and communicates with the through slot. Thus, through the detachable design, the back cover dismounting jig can be applied to different foldable-screen mobile phones or ordinary mobile phones, and through the arrangement of the hand holding opening, the foldable-screen mobile phone can be easily taken out from the through slot.

[0016] In order to better understand and implement, the following will be described in detail in combination with the drawings. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is in combination with the drawing and example, and the utility model is further detailedly explained.It should be understood that the specific example described here is only used to explain the utility model, and is not used to limit the utility model.

[0027] Please refer to Figures 1-6 The embodiment provides a folding screen mobile phone back cover dismounting jig, including base (not shown in drawing), mounting plate 10, first suction cup 20, second suction cup 30 and mobile phone profiling plate 40, the mounting plate 10 is arranged on the base, the first suction cup 20 and second suction cup 30 are arranged on the mounting plate 10, the mounting plate 10 is provided with through hole 11 in the position of air hole 73 corresponding to the first suction cup 20 and second suction cup 30 respectively, and the air pipe that is communicated with the air hole of the first suction cup and second suction cup passes through the through hole, the mobile phone profiling plate 40 is located above the first suction cup 20 and second suction cup 30, and is fixedly connected with the base, the mobile phone profiling plate 40 is provided with through slot 41 for placing folding screen mobile phone, the boss 42 for supporting the frame of folding screen mobile phone 50 is arranged in the through slot 41, and the first suction cup 20 and second suction cup 30 are arranged in the through slot 41.

[0028] The folding screen mobile phone back cover dismounting jig provided by the embodiment is characterized in that a through slot 41 is arranged on the mobile phone profiling plate 40 to place the folding screen mobile phone 50; a boss 42 is designed in the through slot 41 to support the upper middle frame 51 and the lower middle frame 52 of the folding screen mobile phone 50; when the first suction cup 20 and the second suction cup 30 are vacuumized, a low-pressure area is formed in the suction cup, which attracts the back cover to make the upper back cover 53 and the lower back cover 54 respectively adhere to the first suction cup 20 and the second suction cup 30; since the upper middle frame 51 and the lower middle frame 52 are supported by the boss 42 and remain unmoved, the upper back cover 53 and the lower back cover 54 are separated from the upper middle frame 51 and the lower middle frame 52 respectively to form a gap due to the downward suction force; after the vacuumization is stopped, the mobile phone is manually picked up and the back cover is slowly pulled open, which saves time and effort and is less likely to damage the product. It should be noted that the back cover of the folding screen mobile phone 50 can be heated before the back cover is dismounted, and the back cover is dismounted by using the folding screen mobile phone back cover dismounting jig after the foam glue between the back cover and the middle frame is softened, which makes the dismounting easier.

[0029] In the embodiment, the folding screen mobile phone 50 is in a rectangular structure, so the through slot 41 on the mobile phone profiling plate 40 is a rectangular through slot, and preferably, the length and width of the rectangular through slot are the same as those of the folding screen mobile phone 50. Thus, the rectangular through slot with the same length and width as the folding screen mobile phone 50 is arranged on the mobile phone profiling plate 40 to realize the accurate positioning and fixing of the folding screen mobile phone 50, so that the back cover is adsorbed by the suction cup.

[0030] In the embodiment, the boss 42 is a boss formed by extending inward from the inner side of the through slot 41. The boss 42 is integrally formed with the through slot 41. Of course, in other alternative embodiments, the boss 42 and the through slot 41 can be detachably connected, such as being connected by buckling or screwing, etc., so that the boss 42 is replaced to adapt to the folding screen mobile phone 50 with the same size but different thickness of the frame.

[0031] In the embodiment, the first and second suction cups 20 and 30 are rectangular, and are arranged along the length direction of the through slot 41 in sequence. The first and second suction cups 20 and 30 are flush in the height direction, and the two adjacent sides of the first and second suction cups 20 and 30 are flat surfaces 74 that are attached to the back cover. The remaining sides of the first and second suction cups 20 and 30 are curved surfaces 75 that are attached to the edges of the back cover. Thus, the sides of the first and second suction cups 20 and 30 are matched with the edge shapes of the upper and lower back covers 53 and 51, so that the first and second suction cups 20 and 30 are tightly attached to the upper and lower back covers 53 and 51, respectively, thereby reducing the gap and air leakage, and enhancing the suction force of the suction cups. Of course, in other implementable manners, the first and second suction cups 20 and 30 are not limited to be rectangular, but can be circular or other polygons.

[0032] In the embodiment, the through slot 41 further comprises a support beam 43 for supporting the rotating shaft of the folding screen mobile phone. The support beam 43 is located between the first and second suction cups 20 and 30, and the top of the support beam 43 is flush with the flat surface 74. Thus, when the back cover is suctioned, the support beam 43 can support the rotating shaft of the folding screen mobile phone, and can avoid deformation or damage of the rotating shaft of the folding screen mobile phone under the suction force. As a preferred, the support beam 43 is integrally designed with the mobile phone profiling plate 40. Of course, in other alternative embodiments, the support beam 43 can be detachably connected with the mobile phone profiling plate 40, such as being connected with the mobile phone profiling plate 40 through buckling or screwing, and the support beam 43 can be replaced to adapt to folding screen mobile phones 50 of different thicknesses.

[0033] In the embodiment, the surfaces of the two adjacent sides of the first and second suction cups 20 and 30 are lower than the surfaces of the remaining sides of the first and second suction cups 20 and 30. Thus, when the folding screen mobile phone 50 is placed in the through slot 41, the edges of the first and second suction cups 20 and 30 are in contact with the upper and lower back covers 53 and 54, respectively, to form a closed space for subsequent effective suction.

[0034] In the embodiment, the suction surfaces of the first and second suction cups 20 and 30 are inwardly recessed to form suction cavities 71, and a plurality of protrusions 72 are arranged in the suction cavities 71. Thus, the protrusions 72 can form a tighter contact between the suction cups and the back cover, reduce air leakage points, and increase the effective contact area between the suction cups and the back cover, thereby greatly enhancing the suction force of the suction cups. In addition, a larger friction force can be generated between the suction cups and the back cover to prevent relative sliding between the suction cups and the back cover, and maintain a stable suction state.

[0035] As preferred, the protrusions 72 are lower than the plane 74. Thus, when vacuumizing, the first and second suction cups 20 and 30 will be deformed under the action of atmospheric pressure, so that the protrusions 72 are closely attached to the surface of the back cover, thereby enhancing the suction force of the suction cups and maintaining a stable suction state; after stopping vacuumizing, the first and second suction cups 20 and 30 will recover their shapes under the action of atmospheric pressure, so that the protrusions 72 are separated from the surface of the back cover, thereby facilitating the removal of the mobile phone from the mobile phone profiling plate.

[0036] As preferred, the first and second suction cups 20 and 30 are both silica gel profiling suction cups. Specifically, the first and second suction cups 20 and 30 are silica gel profiling suction cups with a hardness of 50°. Thus, the silica gel profiling suction cups can be firmly attached to the smooth surface of the back cover of the folding screen mobile phone under vacuum. In addition, silica gel is soft and wear-resistant, and the silica gel profiling suction cups can avoid scratching or damaging the contact surface when attaching the back cover of the folding screen mobile phone. The silica gel profiling suction cups with a hardness of 50° are softer and can generate greater suction force. Of course, in other alternative embodiments, the first and second suction cups 20 and 30 can be made of polyurethane, silicone rubber or fluororubber.

[0037] As preferred, the protrusions 72 are rectangular, and the protrusions 72 are arranged in a matrix within the suction cavity 71. Thus, the design of the rectangular protrusions can increase the contact area with the back cover, and the matrix arrangement of the rectangular protrusions can make the rectangular protrusions uniformly attached to the surface of the back cover, so that a uniform friction force is generated between the suction cups and the back cover, thereby ensuring a stable suction state between the suction cups and the back cover. Of course, in other alternative embodiments, the protrusions are not limited to rectangular, and other polygons such as circular, trapezoidal, pentagonal, etc. are also available.

[0038] As preferred, the first suction cup 20 is further provided with a second cavity 21 for accommodating the camera of the folding screen mobile phone, and the second cavity 21 is arranged within the suction cavity 71. Thus, when the first suction cup 20 is vacuumized, the camera 56 of the folding screen mobile phone 50 can be protected by the second cavity 21, thereby avoiding the influence or damage of the camera 56.

[0039] As preferred, the second suction cup 30 is further provided with a second protrusion 31, and the second protrusion 31 extends inwardly from the inner side of the suction cavity 21. Thus, by designing the second protrusion 31, the suction force of the second suction cup 30 is further enhanced. In this embodiment, the second protrusion 31 is rectangular. Of course, in other alternative embodiments, the second protrusion 31 is not limited to rectangular, and other polygons such as circular, trapezoidal, pentagonal, etc. are also available.

Of course, in other alternative embodiments, the air holes 73 of the first suction cup 20 and the second suction cup 30 are not limited to one or two, but can be multiple, so as to generate uniform suction force and enhance the suction force of the suction cup.

[0041] In this embodiment, the mounting plate 10 is provided with a through hole 11 at the position corresponding to the air hole 73 of the first suction cup 20 and the second suction cup 30. Specifically, the through hole 11 includes a first through hole 111 and a second through hole 112, the first through hole 111 is a round hole, and the first through hole 111 is provided corresponding to the air hole 73 of the first suction cup 20; the second through hole 112 is a long strip through hole, and the second through hole 112 is provided corresponding to the two air holes 73 of the second suction cup 30. The jig also includes an air hole joint 60 corresponding to the number of air holes 73, one end of the air hole joint 60 respectively passes through the first through hole 111 and the second through hole 112 and is connected with the above-mentioned air hole 73, the other end of the air hole joint 60 is connected with the vacuumizing device through the air pipe. The specific structure of the vacuumizing device, how to install and how to layout the air pipe can be easily obtained by those skilled in the art, so here is not repeated.

[0042] In this embodiment, the mobile phone profiling plate 40 is detachably arranged on the base. Therefore, through the detachable design, the back cover dismounting jig can be suitable for different folding screen mobile phones or ordinary mobile phones. As a preferred, the mobile phone profiling plate 40 is connected with the base through screws. Of course, in other alternative embodiments, the mobile phone profiling plate 40 can be buckled with the base.

[0043] In this embodiment, the mobile phone profiling plate 40 is also provided with a hand buckle opening 44, which is arranged on both sides of the through slot 41 and communicates with the through slot. Therefore, by setting the hand buckle opening 44, it is convenient to take out the folding screen mobile phone 50 from the through slot 41.

[0044] When the folding screen mobile phone back cover dismounting jig is carried out, the folding screen mobile phone which has been subjected to back cover heating treatment is placed at the through slot of the mobile phone profiling plate, the first suction cup and the second suction cup are controlled to be vacuumized, so that the upper back cover and the lower back cover are respectively subjected to the downward suction force of the first suction cup and the second suction cup, and are separated from the upper middle frame and the lower middle frame to generate a gap, after the vacuumization is completed and stopped, the mobile phone is taken out through the hand buckle opening, and the back cover is slowly pulled open.
