Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a frame preparation apparatus, a frame preparation method, a frame, and an electronic device. Background Technology

[0002] Electronic devices consist of a mid-frame and a display screen. A protective frame exists between the display screen's edge and the mid-frame to prevent the mid-frame from colliding with the display screen. In related technologies, liquid adhesive can be applied to the display screen using a dispensing machine, which then cures to form the frame. However, frames produced by dispensing machines are often irregular in size, resulting in poor dimensional consistency. Alternatively, frames can be formed using low-pressure injection molding or 3D printing, but these methods are more expensive.

[0003] In related technologies, it is difficult for frame preparation equipment to simultaneously achieve both low cost and good dimensional consistency. Summary of the Invention

[0004] This application provides a frame preparation device, a frame preparation method, a frame, and an electronic device. The frame preparation device can achieve both low cost and good dimensional consistency when preparing frames.

[0005] The first aspect of this application provides a frame preparation device, including a mold device, which includes a first mold and a second mold. The first mold has a receiving groove for accommodating at least a portion of the display screen. When the display screen is located in the receiving groove, the second mold is disposed on the side of the display screen opposite to the first mold. The first mold, the display screen, and the second mold form a dispensing space with an opening on one side, which is used to accommodate liquid adhesive. The frame formed by the curing of the liquid adhesive is connected to the display screen.

[0006] In the frame preparation equipment of this application embodiment, the dispensing space is connected to the atmosphere through an opening. Therefore, there is no need to evacuate the dispensing space, which can reduce the equipment cost. The liquid adhesive also flows at a high rate in the open dispensing space, resulting in high efficiency in frame preparation and reduced time costs. Compared to low-pressure injection molding equipment, the open dispensing space allows for faster liquid adhesive flow, eliminating the need to increase the internal dimensions of the dispensing space to increase flow speed. This reduces the amount of raw materials used in frame preparation, lowering material costs. The first mold, display screen, and second mold limit the liquid adhesive from three sides, ensuring that the sides facing these three sides have regular shapes. For the side facing the opening, gravity also contributes to a more regular shape, resulting in better dimensional consistency of the formed frame. Therefore, the frame preparation equipment provided in this application embodiment can combine lower cost with better dimensional consistency.

[0007] In some possible implementations, the first mold includes a first base plate and a first side plate surrounding the first base plate, the first base plate and the first side plate forming a receiving groove; the receiving groove is used to accommodate the entire display screen; when the entire display screen is located in the receiving groove, a second mold is used to be disposed on the side of the display screen opposite to the first base plate, and at least part of the second mold is located in the receiving groove, the second mold and the first side plate have a first gap, so that the first side plate, the display screen and the second mold form a dispensing space with an opening on one side. The size of the dispensing space along the length or width direction can be determined based on the first gap between the edge of the second mold and the first side plate, making the formation of the dispensing space relatively simple.

[0008] In some possible implementations, the first side plate limits the dispensing space from a first direction; the display screen limits the dispensing space from a second direction; and the second mold limits the dispensing space from a third direction. The first direction and the third direction are opposite, and the opening is opposite to the second direction. Therefore, by simply improving the flatness of the inner surface of the first side plate and the outer surface of the second mold, the frame can achieve good dimensional consistency. The flatness of the inner surface of the first side plate is easy to ensure, and the flatness of the outer surface of the second mold is also easy to ensure.

[0009] In some possible implementations, the first side plate has a first surface facing away from the first base plate, with an opening located on one side of the first surface; the frame preparation equipment further includes a first centrifugal device; the first centrifugal device is used to drive the mold device to rotate, so that the liquid adhesive in the dispensing space flows level with the first surface. The first centrifugal device can drive the mold to rotate, so that the bulge portion flows level with the first surface of the first side plate under the action of centrifugal force, thereby making the four sides of the formed frame relatively flat.

[0010] In some possible implementations, the first centrifugal device includes a rotating platform and a rotating shaft capable of driving the rotating platform to rotate. A mold device is horizontally disposed on the rotating platform, and a first mold is connected to the rotating platform. The mold device is coaxially disposed with the rotating shaft. As the rotating shaft rotates, excess liquid adhesive in the dispensing space can be simultaneously ejected, resulting in high efficiency in leveling the liquid adhesive with the first surface.

[0011] In some possible implementations, the second mold includes a second surface located on the same side of the adhesive frame preparation equipment as the first surface; the distance between the second surface and the first base plate is greater than or equal to the distance between the first surface and the first base plate. When the distance between the second surface and the first base plate is equal to the distance between the first surface and the first base plate, both the first and second surfaces can serve as reference surfaces for the dispensing space, making the dispensing amount more accurate. When the distance between the second surface and the first base plate is greater than the distance between the first surface and the first base plate, the second mold can prevent liquid adhesive in the dispensing space from flowing across the second surface onto the display module.

[0012] In some possible implementations, the first mold further includes a first limiting plate that abuts against the first side plate, with the side of the first limiting plate facing the display screen covering the edge area of ​​the display screen. The first limiting plate can cover the edge area of ​​the stepped surface, thereby preventing the formation of a plastic frame on the edge area of ​​the cover plate.

[0013] In some possible implementations, the display screen includes a display module and a cover plate, with a stepped surface between the cover plate and the display module; a first mold includes a second base plate and a second side plate surrounding the second base plate, the second base plate and the second side plate forming a receiving groove; the receiving groove is used to receive the cover plate of the display screen; when the cover plate is located in the receiving groove, the second mold is used to be positioned on the side of the display screen opposite to the second base plate; the stepped surface, the side of the display module, and the second mold form a dispensing space with an opening on one side. The size of the dispensing space along the thickness direction can be determined based on the distance between the side of the second mold facing the stepped surface and the stepped surface; the size of the dispensing space along the length or width direction can be determined based on the distance between the side of the second mold facing the second side plate and the second side plate, making the formation of the dispensing space relatively simple.

[0014] In some possible implementations, the second mold includes adjacent third and fourth surfaces. The third surface is parallel to the side of the display module, and the fourth surface is opposite to the stepped surface. The stepped surface limits the dispensing space from a fourth direction, and the side and third surface of the display module limit the dispensing space from a fifth direction. The fourth surface limits the dispensing space from a sixth direction. The opening is opposite to the fifth direction. By simply improving the flatness of the third and fourth surfaces of the second mold, the glue frame can achieve good dimensional consistency.

[0015] In some possible implementations, the second mold further includes a fifth surface, which is connected to the fourth surface and parallel to the third surface, with an opening located on one side of the fifth surface; the glue frame preparation equipment further includes a second centrifugal device; the second centrifugal device is used to drive the mold device to rotate, so as to level the liquid glue in the dispensing space with the fifth surface, so that the four sides of the glue frame have good dimensional consistency.

[0016] In some possible implementations, the second centrifugal device is a rotating column, the mold assembly is placed vertically, and the first mold is connected to the rotating column. By placing the mold assembly vertically and directly connecting the first mold to the rotating column, the rotating column does not need to drive the mold assembly to rotate through an adapter, thus reducing the load on the second centrifugal device and further reducing the production cost of the plastic frame.

[0017] In some possible implementations, the first mold further includes a second limiting plate that abuts against the second side plate and a portion of the display screen, with the area where the second limiting plate abuts against the display screen covering the edge area of ​​the display screen.

[0018] In some possible implementations, the sides of the first and second molds that contact the plastic frame have a release coating. The release coating facilitates the separation of the first and second molds from the plastic frame.

[0019] In some possible implementations, the first mold and the second mold are silicone molds. Silicone molds facilitate the separation of the first and second molds from the plastic frame.

[0020] The second aspect of this application provides a method for preparing a frame, including:

[0021] A first mold, a display screen, and a second mold are provided, which together form a dispensing space with an opening on one side;

[0022] Dispense liquid adhesive within the dispensing space;

[0023] The cured liquid adhesive forms a glue frame;

[0024] Demold the first and second molds from the plastic frame.

[0025] The adhesive frame preparation method provided in this application can form a dispensing space with an opening on one side by simply arranging and assembling a first mold, a display screen, and a second mold. The shape of the liquid adhesive can be displayed from different directions through the first mold, the display screen, and the second mold, resulting in good dimensional consistency of the adhesive frame formed by the cured liquid adhesive. The dispensing space is connected to the atmosphere through the opening, allowing the liquid adhesive to flow quickly within the dispensing space to fill it. This saves time in preparing the adhesive frame and eliminates the need for the vacuuming step in related technologies, simplifying the preparation process.

[0026] In some possible implementations, before the cured liquid adhesive forms the frame, the process further includes leveling the liquid adhesive on one side of the opening so that the surface of the liquid adhesive is flush with the plane containing the opening. Centrifugal force can be used to level the bulge, thereby ensuring that all four sides of the formed frame are relatively flat.

[0027] A third aspect of this application provides a frame, which is manufactured using the frame manufacturing equipment or method described above, and is connected to a display screen. The frame manufactured using the frame manufacturing equipment provided in this application has lower cost and better dimensional consistency.

[0028] A fourth aspect of this application provides an electronic device including a mid-frame, a display screen, and the aforementioned retaining frame. The cover plate of the display screen is connected to the mid-frame, and the retaining frame is disposed between the display module of the display screen and the mid-frame. The retaining frame fills the space between a first side of the display module and a second sidewall of a stepped portion, preventing the second sidewall from impacting the first side of the display module. Furthermore, the thickness of the retaining frame between the first side and the second sidewall is less than the second gap, thereby increasing the screen-to-body ratio of the electronic device.

[0083] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0084] This application provides an electronic device. The electronic device can be referred to as a user equipment (UE) or terminal, etc. For example, the electronic device can be a portable Android device (PAD), a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device, an in-vehicle device, a wearable device, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. This application does not specifically limit the form of the electronic device.

[0085] Figure 1 This is a schematic diagram of the electronic device. Figure 2 for Figure 1 An explosion diagram. Figure 3 For along Figure 1 A cross-sectional view of plane AA.

[0086] See Figures 1 to 3As shown, the electronic device 100 is illustrated as a handheld device with wireless communication capabilities. For example, a handheld device with wireless communication capabilities can be a mobile phone. The electronic device 100 can be rectangular, and includes a length direction X, a width direction Y, and a thickness direction Z.

[0087] Electronic device 100 includes a housing 110 and a display screen 120. The housing 110 includes a mid-frame 111 and a back cover 112. The mid-frame 111 includes a middle plate 1111 and a frame 1112 connected to each other. The frame 1112 can be a rectangular frame, surrounding the peripheral edge of the middle plate 1111 and connected to its periphery. The back cover 112 and the display screen 120 are located on opposite sides of the mid-frame 111. The back cover 112 and the mid-frame 111 can form a cavity, in which components such as a circuit board 130 or a battery can be housed.

[0088] Electronic devices can be mounted on the circuit board 130. For example, electronic devices may include processor modules, system-on-chip (SoC), storage modules, communication modules, radio frequency modules, charging management modules, power management ICs (PMICs), etc.

[0089] The display screen 120 can be an organic light-emitting diode (OLED) display screen. The display screen 120 can also be a micro organic light-emitting diode (MOLED) display screen, or a micro organic light-emitting diode (MOLED) display screen, etc.

[0090] Figure 4 This is a schematic diagram of the structure of a display screen in an electronic device.

[0091] See Figure 3 and Figure 4 As shown, the display screen 120 includes a display module 121 and a cover plate 122. The display module 121 is the unit in the display screen 120 that performs the display function. The cover plate 122 is placed on the display module 121 to protect it. When the cover plate 122 is placed on the display module 121, it can be connected to the display module 121 by means of adhesive bonding, hot pressing, etc., to achieve the fixation of the cover plate 122 on the display module 121. The cover plate 122 can be a light-transmitting plate structure to facilitate the display of the display module 121. For example, the cover plate 122 can be a transparent glass plate.

[0092] The processor module on the circuit board 130 can be connected to the display screen 120 to control the display brightness of the display screen 120, reduce power consumption, and adjust the display brightness of the display screen 120 according to the intensity of the ambient light outside the electronic device 100, so that the display screen 120 can achieve better display effect and improve user experience. The battery is used to power the display screen 120.

[0093] The projected area of ​​the display module 121 on the cover plate 122 is smaller than the area of ​​the cover plate 122, so as to form a stepped surface 123 between the cover plate 122 and the display module 121. The display module 121 has a first side surface 1211, and the cover plate 122 has a second side surface 1221. It should be noted that the display module 121 typically includes multiple functional layers 1212, and steps may exist between the multiple functional layers 1212. The first side surface 1211 refers to the side surface of the functional layer 1212 closest to the edge of the cover plate 122.

[0094] Figure 5 This is a schematic diagram of the structure of the middle frame in an electronic device.

[0095] See Figure 5 As shown, there is a step portion 1113 between the frame 1112 and the middle plate 1111. The frame 1112 has a first sidewall 1112a. The step portion 1113 includes a mounting surface 1113a and a second sidewall 1113b. The first sidewall 1112a, the mounting surface 1113a and the second sidewall 1113b are connected in sequence.

[0096] Please continue reading Figures 3 to 5 As shown, when the display screen 120 is installed onto the middle frame 111, the stepped surface 123 overlaps the mounting surface 1113a, and the stepped surface 123 and the mounting surface 1113a can be bonded together by adhesive 140.

[0097] The second side 1221 of the cover plate 122 has a first gap A1 with the first side wall 1112a. The first gap A1 is the installation gap, that is, the distance between the two first side walls 1112a that are opposite each other along the length direction X (or along the width direction Y) is greater than the distance between the two second side walls 1221 that are opposite each other along the length direction X (or the width direction Y), so that the display screen 120 can be smoothly assembled with the middle frame 111.

[0098] There is a second gap A2 between the first side 1211 of the display module 121 and the second side wall 1113b. That is, the distance between the two second side walls 1113b that are opposite each other along the length direction X (or along the width direction Y) is greater than the distance between the two first side walls 1211 that are opposite each other along the length direction X (or the width direction Y). Therefore, when the electronic device 100 is hit by an external force, the second side wall 1113b can be prevented from colliding with the first side 1211 of the display module 121.

[0099] Figure 6 This is a schematic diagram of the structure of an electronic device after the display screen has been moved relative to the mid-frame.

[0100] See Figure 6 As shown, the second gap A2 typically needs to be larger than the first gap A1. For example, the second gap A2 can be more than 1.5 times the first gap A1. Thus, when the display 120 is assembled with the middle frame 111, even if the second sidewall 1221 along the length direction X (or width direction Y) abuts against the first sidewall 1112a, the second sidewall 1113b will not collide with the first sidewall 1211 of the display module 121. However, setting the second gap A2 to be larger will reduce the screen-to-body ratio of the electronic device 100.

[0101] A protective frame can be installed around the display module 121 to protect it. The thickness of the frame can be set to be less than the second gap A2, thereby increasing the screen-to-body ratio of the electronic device 100.

[0102] Figure 7 This is a schematic diagram of the preparation process of the adhesive frame in related technology one.

[0103] See Figure 7As shown, the plastic frame can be prepared using a low-pressure injection molding machine 10. The low-pressure injection molding machine 10 includes an outer female mold 11, an outer male mold 12, and an inner mold 13. The inner mold 13 and the display screen 120 are placed sequentially in the outer female mold 11, and then the outer male mold 12 is fastened to the outer female mold 11. The outer female mold 11 has a first through hole 11a, and the inner mold 13 has a second through hole 13a, with the first through hole 11a and the second through hole 13a aligned. The low-pressure injection molding machine 10 also includes a vacuuming device (not shown in the figure) and an injection molding device 14. The vacuuming device evacuates the space formed in the outer female mold 11 and the outer male mold 12, and then the injection molding device 14 injects liquid adhesive through the first through hole 11a and the second through hole 13a. After the liquid adhesive solidifies, it forms the plastic frame. The low-pressure injection molding equipment 10 has a high equipment cost. The space formed by the inner mold 13 and the display screen 120 is a sealed space, and the flow rate of liquid adhesive in the sealed space is slow, resulting in low efficiency in the preparation of the mold frame and thus increasing the time cost of mold frame preparation. In order to increase the flow rate of liquid adhesive, the internal dimensions of the inner mold 13 are usually large, resulting in a larger amount of raw materials used in the preparation of the mold frame and increasing the material cost of the mold frame. In addition, the large size of the mold frame has a limited contribution to reducing the screen-to-body ratio of the electronic device 100.

[0104] In related technology two, a plastic frame can be set around the display screen 120 using 3D printing equipment. However, 3D printing equipment is expensive and has low production efficiency. In related technology three, a plastic frame can be prepared by directly dispensing glue onto the display screen 120 using a dispensing machine. However, the plastic frame prepared by the dispensing machine is irregular in size, resulting in poor dimensional consistency.

[0105] In summary, among the related technologies, it is difficult for equipment for preparing adhesive frames to simultaneously achieve both low cost and good dimensional consistency.

[0106] Based on this, embodiments of this application provide a frame preparation device, a frame preparation method, a frame, and an electronic device. The frame preparation device can achieve both low cost and good dimensional consistency when preparing frames.

Figure 1 , Figure 12 A schematic diagram of the process of preparing a glue frame using the glue frame preparation equipment provided in this application embodiment. Figure 2 It should be noted that, in Figure 8 and Figure 10The display screen is shown in the subsequent structural diagrams to clearly illustrate its positional relationship with the mold assembly 210. Furthermore, the location of the opening 213 is schematically shown with dashed lines.

[0108] See Figures 8 to 12 As shown, the frame preparation equipment 200 includes a mold device 210, which includes a first mold 211 and a second mold 212. The first mold 211 has a receiving groove 2111 for receiving at least a portion of the display screen 120. When the display screen 120 is located in the receiving groove 2111, the second mold 212 is used to be positioned on the side of the display screen 120 opposite to the first mold 211. The first mold 211, the display screen 120, and the second mold 212 form a dispensing space 214 with an opening 213 on one side. The dispensing space 214 is used to receive liquid adhesive 300. The frame 150 formed by the curing of the liquid adhesive 300 is connected to the display screen 120.

[0109] The first mold 211 supports the display screen 120 and the second mold 212. Specifically, a receiving groove 2111 can be formed in the first mold 211, and the display screen 120 can be placed in the receiving groove 2111. The display screen 120 can be completely located in the receiving groove 2111, or it can be partially located in the receiving groove 2111. Figure 8 In the embodiment shown, the entire display screen 120 is located within the receiving slot 2111. Figure 10 In the illustrated embodiment, the display screen 120 is partially located in the receiving groove 2111. The cover plate 122 of the display screen 120 faces the first mold 211. The second mold 212 may be disposed on one side of the display module 121 of the display screen 120.

[0110] Please continue reading Figure 8 and Figure 10 As shown, the first mold 211, the display screen 120, and the second mold 212 enclose a roughly rectangular dispensing space 214. The three sides of the rectangle are limited by the first mold 211, the display screen 120, and the second mold 212. An opening 213 is provided on one side of the rectangle, communicating with the dispensing space 214. Thus, the dispensing space 214 can communicate with the atmosphere through the opening 213.

[0111] Please continue reading Figure 11As shown, firstly, a first mold 211 is prepared; then, the display screen 120 and the second mold 212 are placed sequentially in the receiving groove 2111 to form a dispensing space 214 with an opening 213; liquid adhesive 300 is dispensed into the dispensing space 214 through the opening 213, filling the dispensing space 214; after the liquid adhesive 300 cures, it forms a frame 150. When the liquid adhesive 300 fills the dispensing space 214, the first mold 211, the display screen 120, and the second mold 212 limit the liquid adhesive from three sides, ensuring that the side of the liquid adhesive 300 facing these three sides has a regular shape. Therefore, the side of the cured frame 150 facing these three sides also has a regular shape.

[0112] Please continue reading Figure 12 As shown, firstly, a first mold 211 is prepared; then, the display screen 120 is placed in the receiving groove 2111, and the second mold 212 is placed on the display screen 120. After assembling the first mold 211, the display screen 120, and the second mold 212, the mold device 210 is rotated 90° so that the mold device 210 is placed vertically with the opening 213 facing upwards, so that liquid glue can be dispensed into the dispensing space 214 through the opening 213; the subsequent process is the same as... Figure 11 The implementation methods shown are the same, and will not be described in detail here. It should be noted that... Figure 12 In the embodiment shown, after the liquid adhesive 300 on one side of the display screen 120 has cured, adhesive is then applied from the other side.

[0113] The dispensing space 214 is connected to the atmosphere through the opening 213, thus eliminating the need for vacuuming the dispensing space 214 and reducing the equipment cost of the frame preparation equipment 200. The liquid adhesive 300 also flows at a relatively high rate in the open dispensing space 214, resulting in higher efficiency in the frame preparation equipment 200 and reduced time costs for frame preparation. Compared to low-pressure injection molding equipment, the open dispensing space 214 and the inherently faster flow rate of the liquid adhesive 300 eliminate the need to increase the internal dimensions of the dispensing space 214 to increase the flow rate, thereby reducing the amount of raw materials used in frame preparation and lowering material costs. The first mold 211, the display screen 120, and the second mold 212 limit the liquid adhesive from three sides, ensuring that the side of the liquid adhesive 300 facing these three sides has a regular shape. For the side facing the opening 213, due to gravity, the shape of the liquid adhesive 300 towards this side is also relatively regular, resulting in good dimensional consistency of the formed adhesive frame 150. Therefore, the adhesive frame preparation equipment 200 provided in this embodiment can combine low cost and good dimensional consistency.

[0114] The first structure of the frame preparation equipment 200 will be described below.

[0115] Please continue reading Figure 8 and Figure 9 As shown, the first mold 211 includes a first base plate 2112 and a first side plate 2113 surrounding the first base plate 2112. The first base plate 2112 and the first side plate 2113 form a receiving groove 2111. The entire display screen 120 is located in the receiving groove 2111. The second mold 212 is disposed on the side of the display screen 120 opposite to the first base plate 2112, and at least part of the second mold 212 is located in the receiving groove 2111. There is a first gap L1 between the second mold 212 and the first side plate 2113, so that the first side plate 2113, the display screen 120 and the second mold 212 form a dispensing space 214 with an opening 213 on one side.

[0116] The cover plate 122 of the display screen 120 is oriented toward the first base plate 2112 to place the display screen 120 in the receiving groove 2111. The first side plate 2113 abuts against the second side 1221 of the cover plate 122 to prevent the display screen 120 from moving in the receiving groove 2111. Then the second mold 212 is placed on the display module 121 of the display screen 120.

[0117] The projected area of ​​the second mold 212 on the display module 121 is smaller than the area of ​​the display module 121, resulting in a first gap L1 between the edge of the second mold 212 and the first side plate 2113. Thus, the first side plate 2113 of the first mold 211, the display screen 120, and the second mold 212 form a dispensing space 214 with an opening 213 on one side. Based on the first gap L1 between the edge of the second mold 212 and the first side plate 2113, the size of the dispensing space 214 along the length direction X or the width direction Y can be determined, making the formation of the dispensing space 214 relatively simple.

[0118] Please continue reading Figure 8 and Figure 9 As shown, the first side plate 2113 limits the dispensing space 214 from the first direction D1; the display screen 120 limits the dispensing space 214 from the second direction D2; the second mold 212 limits the dispensing space 214 from the third direction D3; the first direction D1 and the third direction D3 are opposite to each other, and the opening 213 is opposite to the second direction D2.

[0119] When the display screen 120 is placed in the receiving groove 2111, the first direction D1 and the third direction D3 are two opposite directions along the length direction X (or the width direction Y), and the second direction D2 is consistent with the thickness direction Z.

[0120] Therefore, the inner surface 2113a of the first side plate 2113 faces the second mold 212, and the outer surface 2121 of the second mold 212 faces the first side plate 2113. The inner surface 2113a and the outer surface 2121 can limit the dispensing space from the relative first direction D1 and third direction D3. In other words, by simply improving the flatness of the inner surface 2113a of the first side plate 2113 and the outer surface 2121 of the second mold 212, the glue frame 150 can have better dimensional consistency.

[0121] While forming the receiving groove 2111 in the first mold 211, the inner surface 2113a of the first side plate 2113 is also formed. The space of the receiving groove 2111 is consistent with the size of the display screen 120. Therefore, the space of the receiving groove 2111 is relatively large. Compared with the smaller space inside the inner mold 13 in related technology 1, which makes surface processing difficult, the flatness of the inner surface 2113a is easy to ensure, thereby reducing the processing cost of the frame preparation equipment 200. The outer surface 2121 of the second mold 212 faces the open space. Therefore, the flatness of the outer surface 2121 of the second mold 212 is also easy to ensure, further reducing the processing cost of the frame preparation equipment 200. The step surface 123 of the display screen 120 limits the dispensing space 214 from the second direction D2, and the first side surface 1211 of the display module 121 limits the remaining part of the frame 150, so that the prepared frame 150 can better match the display module 121.

[0122] Figure 13 Schematic diagram of the frame preparation equipment provided in the embodiments of this application Figure 3 , Figure 14 A schematic diagram of the process of preparing a glue frame using the glue frame preparation equipment provided in this application embodiment. Figure 3 .

[0123] See Figure 13 and Figure 14 As shown, the first side plate 2113 has a first surface 2113b facing away from the first bottom plate 2112, and the opening 213 is located on one side of the first surface 2113b; the glue frame preparation equipment 200 also includes a first centrifugal device 220; the first centrifugal device 220 is used to drive the mold device 210 to rotate so that the liquid glue 300 in the dispensing space 214 flows level with the first surface 2113b.

[0124] Due to its viscosity, the liquid adhesive 300 exhibits surface tension, causing a small bulge 310 to form on the side facing the opening 213 after dispensing. This bulge 310 affects the assembly of the adhesive frame 150 and the middle frame 111. The first centrifugal device 220 can rotate the mold device 210, causing the bulge 310 to flow smoothly against the first surface 2113b of the first side plate 2113 under centrifugal force. This results in a relatively flat appearance on all four sides of the formed adhesive frame 150. It should be noted that the distance between the first surface 2113b and the step surface 123 is the same as the thickness Z dimension of the adhesive frame 150.

[0125] Please continue reading Figure 13 and Figure 14 As shown, in one possible implementation, the first centrifugal device 220 includes a rotating platform 221 and a rotating shaft 222 that drives the rotating platform 221 to rotate. The mold device 210 is horizontally arranged on the rotating platform 221, and the first mold 211 is connected to the rotating platform 221. The mold device 210 is coaxially arranged with the rotating shaft 222.

[0126] The rotating shaft 222 can be connected to a motor, which drives the rotating shaft 222 to rotate, and the rotating platform 221 can rotate around the rotating shaft 222. The mold device 210 is horizontally mounted on the rotating platform 221, and the rotating shaft 222 is coaxially arranged with the geometric center of the mold device 210. Since the first mold 211 is connected to the rotating platform 221, the rotation of the rotating platform 221 can drive the mold device 210 to rotate. When the mold device 210 rotates, the bulge portion 310 of the liquid adhesive 300 in the dispensing space 214 that protrudes above the first surface 2113b can be thrown away from the rotating shaft 222 as the mold device 210 rotates, and the liquid adhesive 300 in the dispensing space 214 flows level with the first surface 2113b. The direction of the liquid adhesive 300 being thrown out is shown in the figure by a dashed line with an arrow. By coaxially arranging the mold device 210 and the rotating shaft 222 and connecting the first mold 211 to the rotating platform 221, the excess liquid adhesive 300 in the dispensing space 214 can be simultaneously ejected as the rotating shaft 222 rotates, resulting in a higher efficiency in leveling the liquid adhesive 300 with the first surface 2113b.

[0127] Please continue reading Figure 13 As shown, the second mold 212 includes a second surface 2122, which is located on the same side of the frame preparation equipment 200 as the first surface 2113b; the distance between the second surface 2122 and the first base plate 2112 is equal to the distance between the first surface 2113b and the first base plate 2112.

[0128] In other words, the height of the second mold 212 above the first base plate 2112 is the same as the height of the first side plate 2113 above the first base plate 2112. Therefore, during dispensing, the first surface 2113b and the second surface 2122 can both be used as reference surfaces for the dispensing space 214, making the amount of dispensing in the dispensing space 214 more accurate.

[0129] Figure 15 Schematic diagram of the frame preparation equipment provided in the embodiments of this application Figure 4 .

[0130] See Figure 15 As shown, the distance between the second surface 2122 and the first base plate 2112 is greater than the distance between the first surface 2113b and the first base plate 2112. Therefore, the second mold 212 can prevent the liquid adhesive 300 in the dispensing space 214 from flowing over the second surface 2122 onto the display module 121.

[0131] Figure 16 Schematic diagram of the frame preparation equipment provided in the embodiments of this application Figure 5 .

[0132] See Figure 16 As shown, in Figure 8 Based on the embodiment shown, the first mold 211 further includes a first limiting plate 2114, which abuts against the first side plate 2113, and the side of the first limiting plate 2114 facing the display screen 120 covers the edge area 1231 of the display screen 120.

[0133] Please continue reading Figures 3 to 5 As shown, the area where the stepped surface 123 of the display screen 120 overlaps with the mounting surface 1113a does not require a frame. This area is the edge area 1231. The frame 150 can be avoided in the edge area 1231 by covering the edge area 1231 with the first limiting plate 2114.

[0134] Specifically, the display screen 120 is first placed in the receiving groove 2111, and then the first limiting plate 2114 is placed into the receiving groove 2111, adhering to the inner surface 2113a of the first side plate 2113. The first limiting plate 2114 can cover the edge region 1231 of the stepped surface 123, thereby preventing the formation of a frame 150 on the edge region 1231 of the cover plate 122. The dimension of the edge region 1231 along the length direction X (or the width direction Y) is the same as the dimension of the first limiting plate 2114 along the length direction X (or the width direction Y). Furthermore, when the frame preparation equipment 200 includes the first limiting plate 2114, the side of the first limiting plate 2114 facing away from the first base plate 2112 is flush with the first surface 2113b.

[0135] The second structure of the frame preparation equipment 200 will be described below.

[0136] Please continue reading Figure 10 and Figure 12 As shown, the first mold 211 includes a second base plate 2115 and a second side plate 2116 surrounding the second base plate 2115. The second base plate 2115 and the second side plate 2116 form a receiving groove 2111. The receiving groove 2111 is used to receive the cover plate 122 of the display screen 120. When the cover plate 122 is located in the receiving groove 2111, the second mold 212 is used to be disposed on the side of the display screen 120 opposite to the second base plate 2115. The stepped surface 123, the side of the display module 121, and the second mold 212 form a dispensing space 214 with an opening 213 on one side.

[0137] The dimension of the receiving groove 2111 along the thickness direction Z is the same as that of the cover plate 122 along the thickness direction Z. The cover plate 122 of the display screen 120 is positioned facing the second base plate 2115 to place the display screen 120 in the receiving groove 2111. The side of the rear cover 112 facing away from the second base plate 2115 is flush with the side of the second side plate 2116 facing away from the second base plate 2115, so that only the cover plate 122 portion of the display screen 120 is located in the receiving groove 2111. The second side plate 2116 abuts against the second side surface 1221 of the cover plate 122 to prevent the display screen 120 from moving in the receiving groove 2111. Then, the second mold 212 is placed on the display module 121 of the display screen 120.

[0138] Thus, the step surface 123, the first side surface 1211 of the display module 121, and the second mold 212 form a dispensing space 214 with an opening 213 on one side. The dimension of the dispensing space 214 along the thickness direction Z can be determined based on the distance between the side of the second mold 212 facing the step surface 123 and the step surface 123; the dimension of the dispensing space 214 along the length direction X or the width direction Y can be determined based on the distance between the side of the second mold 212 facing the second side plate 2116 and the second side plate 2116, making the formation of the dispensing space 214 relatively simple.

[0139] Please continue reading Figure 10 and Figure 13 As shown, the second mold 212 includes an adjacent third surface 2123 and a fourth surface 2124. The third surface 2123 is parallel to the side of the display module 121, and the fourth surface 2124 is opposite to the step surface 123. The step surface 123 limits the dispensing space 214 from the fourth direction D4, and the side of the display module 121 and the third surface 2123 limit the dispensing space 214 from the fifth direction D5. The fourth surface 2124 limits the dispensing space 214 from the sixth direction D6. The opening 213 is opposite to the fifth direction D5.

[0140] It should be noted that after assembling the first mold 211, the display screen 120, and the second mold 212, the frame assembly equipment is rotated 90 degrees. When the display screen 120 is placed in the receiving groove 2111, the fourth direction D4 and the sixth direction D6 are two directions along the thickness direction Z, and the fifth direction D5 is consistent with either the length direction X or the width direction Y.

[0141] Therefore, the step surface 123 is opposite to the fourth surface 2124 of the second mold 212, and the step surface 123 and the fourth surface 2124 of the second mold 212 can limit the dispensing space 214 from the fourth direction D4 and the sixth direction D6. The first side surface 1211 of the display module 121 and the third surface 2123 of the second mold 212 simultaneously limit the dispensing space 214 along the fifth direction D5.

[0142] The stepped surface 123 and the first side surface 1211 themselves have high flatness. That is to say, only by improving the flatness of the third surface 2123 and the fourth surface 2124 of the second mold 212, the frame 150 can have good dimensional consistency.

[0143] The third surface 2123 and the fourth surface 2124 of the second mold 212 both face the open space. Therefore, the flatness of the third surface 2123 and the fourth surface 2124 of the second mold 212 is easy to ensure, thereby reducing the processing cost of the glue frame preparation equipment 200.

[0144] Figure 17 Schematic diagram of the frame preparation equipment provided in the embodiments of this application Figure 6 , Figure 18 A schematic diagram of the process of preparing a glue frame using the glue frame preparation equipment provided in this application embodiment. Figure 4 .

[0145] See Figure 17 and Figure 18 As shown, the second mold 212 also includes a fifth surface 2125, which is connected to the fourth surface 2124 and is parallel to the third surface 2123. The opening 213 is located on one side of the fifth surface 2125. The glue frame preparation equipment 200 also includes a second centrifugal device 230. The second centrifugal device 230 is used to drive the mold device 210 to rotate so as to level the liquid glue 300 in the dispensing space 214 with the fifth surface 2125.

[0146] When the mold device 210 is rotated 90° for dispensing, the liquid adhesive 300, due to its viscosity, exhibits surface tension. This causes a small bulge 310 to form on the side of the liquid adhesive 300 facing the opening 213 after dispensing. This bulge 310 can affect the assembly of the glue frame 150 and the middle frame 111. The second centrifugal device 230 can drive the mold device 210 to rotate, causing the bulge 310 to be thrown out of the opening 213 under the action of centrifugal force. Figure 18 The direction of liquid adhesive 300 ejection is indicated by a dotted line with an arrow, which ensures that the side of liquid adhesive 300 facing the opening 213 flows smoothly onto the fifth surface 2125 of the second mold 212, resulting in a relatively flat surface on all four sides of the formed adhesive frame 150. It should be noted that the distance between the fifth surface 2125 and the third surface 2123 is the same as the dimension of the adhesive frame 150 along its thickness (X) or width (Y).

[0147] Please continue reading Figure 17 and Figure 18 As shown, the second centrifugal device 230 is a rotating column, the mold device 210 is placed vertically, and the first mold 211 is connected to the rotating column.

[0148] The rotating column serves as the rotation center of the second centrifugal device 230. After dispensing, when the mold device 210 is in a vertical position, the first mold 211 in the mold device 210 is connected to the rotating column, allowing the rotating column to directly drive the mold device 210 to rotate. As the mold device 210 rotates, the bulge 310 of the liquid adhesive 300 in the dispensing space 214, which protrudes above the first surface 2113b, can be thrown away from the rotating column as the mold device 210 rotates, and the liquid adhesive 300 in the dispensing space 214 flows smoothly onto the fifth surface 2125. By positioning the mold device 210 vertically and directly connecting the first mold 211 to the rotating column, the rotating column does not need to drive the mold device 210 to rotate via a connecting device, thus reducing the load on the second centrifugal device 230 and further lowering the production cost of the adhesive frame 150.

[0149] Figure 19 Schematic diagram of the frame preparation equipment provided in the embodiments of this application Figure 7 .

[0150] See Figure 19 As shown, the first mold 211 also includes a second limiting plate 2117, which abuts against the second side plate 2116 and part of the display screen 120. The area where the second limiting plate 2117 abuts against the display screen 120 covers the edge area of ​​the display screen 120.

[0151] The reason for setting the second limiting plate 2117 is the same as the reason for setting the first limiting plate 2114, and will not be repeated here. Specifically, first, the display screen 120 is placed in the receiving groove 2111, and then the second limiting plate 2117 is pushed towards the receiving groove 2111 while adhering to the upper surface of the second side plate 2116. The first limiting plate 2114 can cover the upper surface and the edge area 1231 of the stepped surface 123, thereby avoiding the formation of a glue frame 150 on the edge area 1231 of the cover plate 122.

[0152] Figure 20 Schematic diagram of the frame preparation equipment provided in the embodiments of this application Figure 8 , Figure 21 Schematic diagram of the frame preparation equipment provided in the embodiments of this application Figure 9 .

[0153] See Figure 21 and Figure 22 As shown, in one possible implementation, the sides of the first mold 211 and the second mold 212 that contact the plastic frame 150 have a release coating 215.

[0154] exist Figure 20 In the molded frame 150, the inner surface 2113a of the first side plate 2113 contacts the frame 150, and the outer surface 2121 of the second mold 212 contacts the frame 150. After the frame 150 is prepared, the first mold 211 and the second mold 212 need to be demolded from the frame 150. To facilitate the demolding of the first mold 211 and the second mold 212 from the frame 150, a release coating 215 can be provided on the inner surface 2113a of the first side plate 2113 and the outer surface 2121 of the second mold 212. The release coating 215 can be made of a material with low adhesion to the frame 150, for example, the release coating 215 can be a silicone coating. Thus, when demolding the first mold 211 and the second mold 212, it is easy to separate the first mold 211 and the second mold 212 from the frame 150.

[0155] exist Figure 21 In the middle, the third surface 2123 and the fourth surface 2124 of the second mold 212 are in contact with the plastic frame 150. A release coating 215 can be provided on the third surface 2123 and the fourth surface 2124.

[0156] In another possible implementation, the first mold 211 and the second mold 212 are silicone molds. This facilitates the separation of the first mold 211 and the second mold 212 from the plastic frame 150.

[0157] Figure 22 This is a schematic diagram of the structure of the adhesive frame provided in an embodiment of this application, wherein, Figure 22The image also shows the display screen of the electronic device, clearly illustrating the positional relationship between the frame and the display screen.

[0158] See Figure 22 As shown, the frame 150 prepared using the frame preparation equipment 200 provided in this application embodiment has a lower cost and better dimensional consistency.

[0159] Figure 23 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0160] See Figure 23 As shown, by providing a frame 150 between the bezel 1112 and the display screen 120, the frame 150 fills the space between the first side 1211 of the display module 121 and the second side wall 1113b of the step portion 1113, which can prevent the second side wall 1113b from impacting the first side 1211 of the display module 121. Furthermore, the thickness of the frame 150 between the first side 1211 and the second side wall 1113b is less than the second gap A2, thereby increasing the screen-to-body ratio of the electronic device 100.

[0161] In addition, the dimensional consistency of the side of the frame 150 facing the middle plate 1111 is good, which also makes it easier for the side of the frame 150 facing the middle plate 1111 to be bonded to the middle plate 1111.

[0162] Figure 24 The process of the frame preparation method provided in the embodiments of this application Figure 1 .

[0163] See Figure 24 As shown in the embodiments of this application, a method for preparing a frame is also provided, including:

[0164] S101, a first mold 211, a display screen 120, and a second mold 212 are provided, the first mold 211, the display screen 120, and the second mold 212 form a dispensing space 214 with an opening 213 on one side.

[0165] The display screen 120 is placed in the receiving groove 2111 of the first mold 211 to limit the position of the display screen 120. Then, the second mold 212 is placed on the side of the display screen 120 facing away from the first mold 211, so that the first mold 211, the display screen 120 and the second mold 212 together form a dispensing space with an opening 213 on one side. Thus, the first mold 211, the display screen 120 and the second mold 212 can limit the dispensing space 214 from different directions.

[0166] S102. Apply liquid adhesive 300 to the dispensing space 214.

[0167] Liquid adhesive 300 is dotted into dispensing space 214. The liquid adhesive 300 flows and fills dispensing space 214, thereby allowing the first mold 211, display screen 120 and second mold 212 to display the shape of liquid adhesive 300 from different directions.

[0168] S103, Curing liquid adhesive 300 forms an adhesive frame 150.

[0169] After the liquid adhesive 300 in the curing dispensing space 214 forms the adhesive frame 150, each side of the adhesive frame 150 is in contact with the dispensing space 214. Therefore, the shape of the dispensing space 214 is the shape of the adhesive frame 150.

[0170] S104. Demold the first mold 211 and the second mold 212 from the plastic frame 150.

[0171] After the plastic frame 150 is formed, the first mold 211 and the second mold 212 need to be demolded from the plastic frame 150 to obtain the plastic frame 150. It should be noted that the plastic frame 150 is connected to the display screen 120.

[0172] The adhesive frame preparation method provided in this application provides a dispensing space 214 with an opening 213 on one side, which can be formed by simply arranging and assembling the first mold 211, the display screen 120, and the second mold 212. The first mold 211, the display screen 120, and the second mold 212 can display the shape of the liquid adhesive 300 from different directions, resulting in good dimensional consistency of the adhesive frame 150 formed by the curing of the liquid adhesive 300. The dispensing space 214 is connected to the atmosphere through the opening 213, allowing the liquid adhesive 300 to flow quickly within the dispensing space 214 to fill it. This saves time in preparing the adhesive frame 150 and eliminates the vacuuming step required in related technologies, simplifying the preparation process of the adhesive frame 150.

[0173] Figure 25 The process of the frame preparation method provided in the embodiments of this application Figure 2 .

[0174] See Figure 25 As shown, in one possible implementation, before the cured liquid adhesive 300 forms the adhesive frame 150, the process further includes: S105, leveling the liquid adhesive 300 on one side of the opening 213 so that the surface of the liquid adhesive 300 is flush with the plane where the opening 213 is located.

[0175] Due to its viscosity, the liquid adhesive 300 exhibits surface tension, causing a small bulge 310 to form on the side facing the opening 213 after dispensing. This bulge 310 can affect the assembly of the adhesive frame 150 and the middle frame 111. Centrifugal force can be used to level the bulge 310, thereby making all four sides of the formed adhesive frame 150 relatively flat.
