[0002] Mobile phones, tablets, and other similar devices are commonly used display devices in people's lives. Display devices typically consist of a screen and a housing. The screen is glued to the housing to secure it in place.

[0003] When the casing is damaged or malfunctions, it is often necessary to separate the casing and screen for repair. In related technologies, separation of the casing and screen is typically achieved by heating the screen to soften the adhesive between the screen and casing, and then applying tension to both the screen and the casing separately to separate them. However, as screen sizes increase, applying tension to both the screen and the casing separately can easily lead to screen breakage.

[0004] Therefore, existing technologies need to be improved and enhanced. Summary of the Invention

[0020] Optionally, the step of cutting off the portion of the housing to be removed from other portions by CNC machining includes:

[0021] Rough machining is performed on the connection between the portion to be removed and the other portions;

[0022] The shell, after rough machining, is then finished to cut off the connection between the part to be removed and the other parts.

[0023] Optionally, the display component further includes an electrical connector extending from the portion to be cut to the other portions;

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0049] Mobile phones, tablets, and other similar devices are commonly used display devices in people's lives. Display devices typically consist of a screen and a housing. The screen is glued to the housing to secure it in place.

[0050] When the casing is damaged or malfunctions, it is often necessary to separate the casing and screen for repair. In related technologies, separation of the casing and screen is typically achieved by heating the screen to soften the adhesive between the screen and casing, and then applying tension to both the screen and the casing separately to separate them. However, as screen sizes increase, applying tension to both the screen and the casing separately can easily lead to screen breakage.

[0051] Based on this, please refer to Figure 1 , Figure 1 This is a schematic diagram illustrating a screen disassembly method provided in an embodiment of this application. The embodiment of this application provides a screen disassembly method, including the following steps:

[0052] 101. Obtain a display component, which includes a screen 100 and a housing 200. The screen 100 is at least partially disposed within the housing 200 and is bonded and fixed to the housing 200.

[0053] 102. At least a portion of the housing 200 is removed from the screen 100 by CNC (computer numerical control) machining.

[0054] In other words, a portion of the housing 200 can be removed first using CNC machining, leaving only a small part of the housing 200 adhered to the screen 100. This facilitates the separation of the screen 100 from the remaining portion of the housing 200, ultimately completing the disassembly of the screen 100. Alternatively, the entire housing 200 can be milled away directly using CNC machining, thus directly completing the disassembly of the screen 100. It is understood that because CNC machining offers advantages such as high precision and speed, the screen disassembly method of this application embodiment has the advantages of high yield and high disassembly efficiency.

[0055] Please continue to refer to this. Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of another screen disassembly method provided in an embodiment of this application. Figure 3 This is a schematic diagram of a display component provided in an embodiment of this application. Based on the method described in the previous embodiment, the following will provide a further detailed description with examples. A screen disassembly method may include the following steps:

[0056] 201. Obtain a display component, which includes a screen 100 and a housing 200. The screen 100 is at least partially disposed within the housing 200 and is bonded and fixed to the housing 200.

[0057] For example, please continue with Chang'an Passenger. Figure 4 , Figure 4 for Figure 3 The diagram shows a cross-sectional view of the display component. The housing 200 may include a bottom wall 21 and a side wall 22. The side wall 22 is disposed around the bottom wall 21 to form a receiving cavity. The screen 100 is at least partially disposed within the receiving cavity and is bonded and fixed to the side wall 22.

[0058] In some embodiments, the screen 100 may include a display assembly 11 and a cover assembly 12. The display assembly 11 is used to display an image. The display assembly 11 is disposed within a receiving cavity. The cover assembly 12 covers the display surface of the display assembly 11 and is bonded to a side wall 22. For example, the side wall 22 is provided with a stepped surface, and the cover assembly 12 rests on the stepped surface and is bonded to the stepped surface with adhesive.

[0059] The display component 11 may be a liquid crystal display (LCD) component. For example, the display component 11 may include a backlight module and an LCD module. The LCD module is disposed on the light-emitting side of the backlight module, so that the backlight module can illuminate the LCD module.

[0060] For example, a liquid crystal display module may include a first polarizer, an array substrate, a liquid crystal layer, a color filter, and a second polarizer arranged in sequence. The backlight module is disposed on the side of the first polarizer away from the array substrate, so that the light emitted by the backlight module passes through the first polarizer, the array substrate, the liquid crystal layer, the color filter, and the second polarizer in sequence to display an image.

[0061] The cover assembly 12 may include a transparent cover such as a glass cover, an acrylic cover, a sapphire cover, etc.

[0062] Of course, in some embodiments, in order to enable the touch function of the display component, the cover assembly 12 also includes a touch module. For example, the touch module may include a capacitive touch module or a resistive touch module disposed on the glass cover.

[0063] The display component 11 may be glued and fixed to the cover plate component 12, or it may be sandwiched between the cover plate component 12 and the bottom wall 21 of the housing 200 to achieve fixation. This application embodiment does not limit this.

[0064] 202. Obtain CNC equipment.

[0065] Please continue to refer to this. Figure 5 , Figure 5 This is a schematic diagram of a vacuum adsorption fixture provided in an embodiment of this application. In some embodiments, the CNC equipment is equipped with a vacuum adsorption fixture 300. The vacuum adsorption fixture 300 may include a carrier 31 and a vacuum pump 32. The carrier 31 is used to support the display component. The carrier 31 is provided with an adsorption channel 311, one end of which is connected to the vacuum pump 32, and the other end of the adsorption channel 311 is open for adsorbing the screen 100 of the display component supported by the carrier 31.

[0066] For example, the carrier 31 is provided with a positioning groove 312, which is used to accommodate and position the display component. One end of the adsorption channel 311 is connected to the vacuum pump 32, and the other end of the adsorption channel 311 is opened in the bottom wall of the positioning groove 312 to adsorb the screen 100 of the display component in the positioning groove 312, so that the display component can be fixed in the positioning groove 312 with the screen 100 facing inward and the housing 200 facing outward. Furthermore, the positioning groove 312 and the vacuum pump 32 can achieve complete positioning of the display component to prevent damage to the screen 100 due to displacement of the display component during subsequent CNC machining. At the same time, since the side of the housing 200 away from the display surface of the screen 100 does not need to be pressed by other parts, it also eliminates the need for frequent tool lifting to avoid other parts during subsequent CNC machining, thereby avoiding low machining efficiency caused by frequent tool lifting.

[0067] Alternatively, the CNC equipment may also include a carrier 31 and a clamping component, wherein the carrier 31 is used to carry the display component and the clamping component is used to clamp and fix the display component carried by the carrier 31.

[0068] For example, the carrier 31 is provided with a positioning groove 312, which is used to accommodate the display component for positioning, so that the display component can be fixed in the positioning groove 312 with the screen 100 facing inward and the housing 200 facing outward. A clamping component can be provided on the carrier 31 for pressing the display component in the positioning groove 312. Such a clamping component may include quick clamps, clamping cylinders, etc., which are not limited in this embodiment. Furthermore, the cooperation of the positioning groove 312 and the clamping component can achieve complete positioning of the display component, so as to prevent the screen 100 from being damaged due to displacement of the display component during subsequent CNC machining.

[0069] In some implementations, the CNC equipment may also include a camera device. The camera device, such as a CCD camera, is used to take photographs of the display components within the positioning slot 312.

[0070] 203. A portion of the housing 200 is removed from the screen 100 by CNC machining.

[0071] Specifically, before removing a portion of the housing through CNC machining, the screen disassembly method also includes: using a vacuum adsorption jig 300 to adsorb the display surface of the screen 100 to fix the screen 100.

[0072] Please continue to refer to this. Figure 6 , Figure 6 for Figure 2 The flowchart illustrates a screen disassembly method. For example, when the screen 100 includes a cover plate assembly 12, the cover plate assembly 12 is bonded and fixed to the housing 200; removing at least a portion of the housing 200 by CNC machining may include:

[0073] The portion 200a to be cut off and the other portions 200b of the housing 200 are cut off by CNC machining; wherein the portion 200a to be cut off and the cover plate assembly 12 are spaced apart from each other, and the other portions 200b are bonded and fixed to the cover plate assembly 12.

[0074] Remove the already cut portion 200a to be removed.

[0075] Therefore, by removing the portion 200a of the housing 200 that is not bonded to the cover assembly 12, the screen 100 and other parts 200b can be separated more easily, thereby improving the yield rate of disassembling the screen 100.

[0076] In some embodiments, when the housing 200 includes a bottom wall 21 and a side wall 22, with the side wall 22 surrounding the bottom wall 21 to form a receiving cavity, and the screen 100 is at least partially disposed within the receiving cavity, and the cover assembly 12 is bonded and fixed to the side wall 22, then cutting off the portion 200a to be removed from the other portions 200b of the housing 200 by CNC machining may include:

[0077] Cut at the junction of the bottom wall 21 and the side wall 22 so that part of the bottom wall 21 is cut off to form the portion to be removed 200a.

[0078] Therefore, after the portion 200a to be removed is cut off, the main parts of the housing 200 can be easily removed, leaving only a small portion, namely the other parts 200b, attached to the screen 100. Consequently, in subsequent processes, separating the exposed and smaller parts 200b is easier and reduces the probability of damaging the screen 100 during separation.

[0079] In some embodiments, the display module of the screen 100 may be spaced apart from the sidewall 22, and in the thickness direction of the screen 100, the orthographic projection of the junction of the portion to be cut 200a and other portions 200b is located outside the orthographic projection of the display component 11.

[0080] This can also be simply understood as cutting away from the display component 11 to form the portion to be removed 200a and other portions 200b. Based on this, on the one hand, since the gap between the cover plate assembly 12 and the bottom wall 21 is relatively large, the cutting tool used by the CNC machine is less likely to collide with the cover plate assembly 12 during the cutting process, thereby reducing the probability of damage to the cover plate assembly 12; on the other hand, since the gap between the display component 11 and the bottom wall 21 is relatively small, the CNC machine starts cutting from the outer periphery of the display component 11, and the cutting tool used by the CNC machine is less likely to collide with the display component 11, thereby reducing the probability of the cutting tool used by the CNC machine colliding with the screen 100 and damaging the screen 100.

[0081] Specifically, cutting at the junction of the bottom wall 21 and the side wall 22 can include controlling the CNC machine to feed the tool from the side of the bottom wall away from the cover plate assembly 12. It is understood that during the downward pressure of the CNC machine's tool, the bottom wall 21 may float up and down in a direction closer to or further away from the cover plate assembly 12. Therefore, since the distance from the junction of the portion to be cut 200a and other portions 200b to the cover plate assembly 12 is relatively large, the CNC machine increases the maximum depth of cut to be greater than the thickness of the bottom wall 21 to ensure that the portion to be cut 200a is completely cut off without easily damaging the screen 100.

[0082] For example, the distance from the junction of the portion to be cut 200a and the other portion 200b to the cover assembly 12 is greater than or equal to 1.5 mm. For instance, the distance from the junction of the portion to be cut 200a and the other portion 200b to the cover assembly 12 can be 1.5 mm, 1.54 mm, 1.61 mm, 1.65 mm, 1.67 mm, 1.78 mm, 1.8 mm, 1.84 mm, 1.91 mm, 2 mm, 2.04 mm, 2.11 mm, 2.2 mm, 2.3 mm, or 2.5 mm; in essence, this is not a limitation.

[0083] In some embodiments, cutting off the portion 200a to be removed from the other portions 200b of the housing 200 by CNC machining may include milling with a milling cutter with a diameter of 4 mm.

[0084] Understandably, on the one hand, using a milling cutter with a diameter of 4 mm can avoid the milling cutter diameter being too large and thus colliding with the display component 11. On the other hand, using a milling cutter with a diameter of 4 mm can also prevent the milling cutter diameter from being too small and affecting the efficiency of milling the part to be removed 200a and other parts 200b of the housing 200. Thus, the screen disassembly method of this application embodiment has the advantages of high efficiency and high yield, thereby meeting the actual production needs.

[0085] Alternatively, cutting off the portion 200a to be removed from the other portions 200b of the housing 200 by CNC machining may include milling with a 6 mm diameter milling cutter.

[0086] Understandably, on the one hand, using a 6mm diameter milling cutter can avoid the milling cutter diameter being too large and thus colliding with the display component 11. On the other hand, using a 6mm diameter milling cutter can also prevent the milling cutter diameter from being too small, which would affect the efficiency of milling the part to be removed 200a and other parts 200b of the housing 200. Thus, the screen disassembly method of this application embodiment has the advantages of high efficiency and high yield, thereby meeting the actual production needs.

[0087] It is also understandable that using a 6 mm diameter milling cutter can increase the efficiency of milling the part 200a to be removed and other parts 200b of the housing 200 by more than 20% compared to using a 4 mm diameter milling cutter.

[0088] In some embodiments, cutting off the portion 200a to be removed from the other portions 200b of the housing 200 by CNC machining may include:

[0089] Rough machining is performed at the connection between the part to be cut 200a and the other part 200b.

[0090] The shell 200, after rough machining, is then finished to cut off the connection between the part to be removed 200a and other parts 200b.

[0091] Therefore, rough machining can quickly thin or even partially sever the connection between the cut-off portion 200a and other portions 200b, and then fine machining can precisely complete the final severance, thereby avoiding damage to the screen 100 by the CNC machine tool. Thus, this embodiment of the application, through a combination of rough and fine machining, can both ensure the yield rate of the screen 100 removal operation and improve the efficiency of the screen 100 removal operation.

[0092] In some embodiments, the screen 100 assembly also includes an electrical connector extending from the portion 200a to be cut to other portions 200b. For example, the electrical connector may include ribbon cables, antenna connecting springs, etc., which are not limited in this application embodiment. During the process of cutting off the portion 200a to be cut from other portions 200b of the housing 200 using CNC machining, the CNC machine tool is controlled to avoid damaging the electrical connector, thereby preventing damage to the electrical connector by the CNC machine tool.

[0093] In some embodiments, cutting off the portion 200a to be removed from the other portions 200b of the housing 200 by CNC machining may include:

[0094] Control the CNC equipment to capture images of the display components;

[0095] Obtain the position information of the display component based on the image of the display component;

[0096] The control unit selects the target infeed point of the CNC equipment based on the position information of the displayed component.

[0097] The CNC machine is controlled to cut off the portion 200a to be removed from the housing 200 and other portions 200b according to the target infeed point.

[0098] Therefore, the CNC machine can be adjusted according to the actual position of the display component, enabling it to more accurately cut the portion 200a to be removed from the housing 200, thereby reducing the probability of the CNC machine's cutting tool colliding with the screen 100 and improving the yield rate of screen 100 disassembly. Furthermore, it eliminates the need for operator tool setting before each CNC operation, further improving the efficiency of screen 100 disassembly.

[0099] In some embodiments, cutting off the portion 200a to be removed from the other portions 200b of the housing 200 by CNC machining may include:

[0100] Control the CNC equipment to capture images of the display components;

[0101] Obtain the model information of the display component based on the image of the display component;

[0102] Select the target tooling path for the CNC equipment based on the model information of the displayed component;

[0103] The CNC equipment cuts off the portion 200a to be removed from the housing 200 and other portions 200b according to the target tool machining path.

[0104] This allows CNC equipment to disassemble display components of different models, improving its versatility. Furthermore, when the display component of the screen 100 to be disassembled changes, it eliminates the need for the operator to re-edit the toolpath on the CNC equipment, thereby reducing the difficulty and increasing the efficiency of screen 100 disassembly. In some embodiments, before removing the cut portion 200a, the screen disassembly method further includes cleaning up the cutting chips generated during the cutting of the portion 200a and other portions 200b, thereby preventing the cutting chips from scratching the screen 100 during the removal of the portion 200a.

[0105] Specifically, after the cutting is completed, the cutting chips generated during the cutting process of the part to be cut 200a and the other part 200b can be blown away by air; or the cutting chips generated during the cutting process of the part to be cut 200a and the other part 200b can be continuously blown away by air during the cutting process and after the cutting is completed. This application embodiment does not limit this.

[0106] 204. After removing the cut-off portion 200a, remove the remaining portion 200b of the housing 200 from the screen 100.

[0107] For example, removing other portions 200b of the housing 200 from the screen 100 may include:

[0108] Heating is applied to other parts 200b and / or screen 100;

[0109] After heating, remove the other part 200b from screen 100.

[0110] Therefore, by heating the screen 100 and / or other parts 200b, the adhesive between the screen 100 and the housing 200 can be softened, making it easier and less laborious to separate other parts 200b from the screen 100, such as the cover plate assembly 12 of the screen 100, thereby improving the efficiency and yield of screen 100 disassembly.

[0111] For example, removing other parts 200b from the screen 100 after heating may include applying forces to the cover assembly 12 and other parts 200b respectively to separate the other parts 200b from the cover assembly 12.

[0112] Based on this, compared to directly applying pulling force to separate the complete housing 200 and screen 100, the disassembly method provided in this application embodiment can increase the yield rate of screen 100 from below 50% to above 95% during disassembly, and reduce the repair time from 10 minutes to 2 minutes.

[0113] In some embodiments, heating other parts 200b and / or screen 100 may include:

[0114] The screen 100 and other parts 200b are transferred from the vacuum adsorption fixture 300 to the second station;

[0115] The other parts 200b and / or screen 100 are heated at the second station.

[0116] This allows the disassembly of another display component, the screen 100, to continue on the vacuum adsorption fixture 300, thereby improving the efficiency of the screen 100 disassembly.

[0117] Optionally, in some embodiments, heating other parts 200b and / or screen 100 may include heating other parts 200b and / or screen 100 located on the fixture, which is not limited in this application embodiment.
