Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0027] In the related art, the electronic device disassembly and assembly equipment usually includes an adsorption mechanism and a fixing fixture. The adsorption mechanism is used to adsorb the touch screen, and the fixing fixture is used to fix the main body. By driving the fixing fixture to rotate, the touch screen and the main body are separated. The fixing fixture is usually rotated manually, which often leads to poor rotation stability of the fixing fixture, which easily causes the electronic device to fail to disassemble; and the use of manual rotation of the fixing fixture also leads to very low efficiency in disassembling the electronic device.

[0028] Based on this, an embodiment of the present disclosure provides a disassembly device for disassembling a touch screen of an electronic device. Figures 1 to 3 As shown, the disassembly device 100 includes a housing 10 , a clamp mechanism 11 and a drive mechanism 12 .

[0029] The clamp mechanism 11 is rotatably disposed on the housing 10 , and the clamp mechanism 11 is configured to fix the main body of the electronic device.

[0030] The driving mechanism 12 includes: a rotating driving member 121 and a rotating driven member 122. The rotating driven member 122 is fixed to the clamping mechanism 11. The side of the rotating driven member 122 away from the clamping mechanism 11 has a contact surface 1221. Along the length direction of the contact surface 1221, the distance between the contact surface 1221 and the clamping mechanism 11 gradually increases. That is, along the length direction L of the contact surface 1221, the contact surface 1221 is an inclined surface. For example, Figure 3 As shown, for three points arranged sequentially along the length direction L of the abutting surface 1221 , the distances between the three points and the clamping mechanism 11 gradually increase, that is, D3>D2>D1.

[0031] The rotation driving member 121 includes a slider 1211 and a driver 1212 driving the slider 1211 to move along the length direction L of the abutting surface 1221 . The slider 1211 abuts against the abutting surface 1221 , and the driver 1212 is fixed on the housing 10 .

[0032] Through the above-mentioned arrangement, when the driver 1212 drives the slider 1211 to move linearly, the slider 1211 always abuts against the abutment surface 1221, and the abutment surface 1221 is arranged at an angle, so that the rotating follower 122 and the clamping mechanism 11 fixed thereto can rotate around the hinge axis between the clamping mechanism 11 and the housing 10, thereby realizing the driving of the clamping mechanism 11 to rotate.

[0033] For the disassembly device 100, during the rotation of the clamp mechanism 11, since the slider 1211 is always in contact with the abutment surface 1221, the rotation stability of the clamp mechanism 11 can be improved, thereby improving the stability of disassembly of the electronic device, and avoiding the failure of disassembly of the electronic device due to factors such as shaking or trembling of the clamp mechanism 11. In addition, the rotating follower 122 can also form a certain degree of shielding on the side of the clamp mechanism 11, which can avoid the contamination of the touch screen and the main body after disassembly due to particles blowing through the outer side during the disassembly of the electronic device, thereby forming a certain degree of protection for the disassembly of the electronic device.

[0034] In some examples, the housing 10 may be Figure 1-2 The rectangular parallelepiped housing shown is conducive to the arrangement of the disassembly device 100.

[0035] Exemplarily, supporting feet may be provided around the bottom of the shell 10 to provide stable support for the disassembly device 100 .

[0036] In some examples, a handle 101 may be further provided on the housing 10 to facilitate an operator to extract the housing 10 and thus facilitate its transportation.

[0037] Exemplarily, two handles 101 may be provided, and the two handles 101 may be arranged on opposite sides of the housing 10 .

[0038] Exemplarily, the handle 101 may be disposed at the middle of the housing 10 along the length direction of the housing 10 .

[0039] In some embodiments, the clamp mechanism 11 is connected to the housing 10 via a hinge shaft 20 , so that the clamp mechanism 11 can rotate relative to the housing 10 .

[0040] In some examples, two bearing seats 102 are provided on the housing 10, the hinge shaft 20 is fixedly connected to the clamp mechanism 11, and both ends of the hinge shaft 20 are mounted on the two bearing seats 102. Thus, the clamp mechanism 11 can rotate around the axis of the hinge shaft 20, so that the clamp mechanism 11 can rotate relative to the housing 10.

[0041] In some examples, the length direction L of the abutment surface 1221 is parallel to the axial direction R of the hinge shaft 20. In this way, the rotation follower 122 is located at one end of the clamp mechanism 11 along the length direction of the clamp mechanism 11. At this time, by driving the slider 1211 to move, the clamp mechanism 11 can be stably driven to rotate.

[0042] In other examples, such as Figure 2 As shown, the length direction L of the abutting surface 1221 is perpendicular to the axial direction R of the hinge shaft 20. In this way, the rotating follower 122 is located on one side of the clamp mechanism 11 along the length direction of the clamp mechanism 11. At this time, the length of the rotating follower 122 can be set relatively long, so that the time available for the clamp mechanism 11 to rotate can be extended, thereby reducing the rotation speed of the clamp mechanism 11, and avoiding damage to the disassembly of the electronic device caused by the clamp mechanism 11 rotating too fast.

[0043] Exemplarily, two driving mechanisms 12 may be provided, and the two driving mechanisms 12 are respectively located on both sides of the clamp mechanism 11 along the length direction of the clamp mechanism 11 , which is beneficial to improving the stability of driving the clamp mechanism 11 .

[0044] In this case, the drivers in the two driving mechanisms 12 need to be driven synchronously, that is, the driving directions and driving frequencies of the two drivers are kept consistent.

[0045] In some embodiments, the distance between the abutting surface 1221 and the clamp mechanism 11 gradually increases along the length direction L of the abutting surface 1221 and in the direction toward the hinge shaft 20. In this configuration, the rotating follower 122 has a larger thickness on the side close to the hinge shaft 20, and the rotating follower 122 has a smaller thickness on the side away from the hinge shaft 20, so that the center of gravity of the rotating follower 122 can be close to the hinge shaft 20, so that the rotation stability of the rotating follower 122 can be improved when the driver 1212 drives the rotating follower 122 to rotate.

[0046] In some embodiments, the abutting surface 1221 includes at least one of an inclined surface and a curved surface. Exemplarily, the abutting surface 1221 includes an inclined surface; further exemplary, the abutting surface 1221 includes a curved surface; further exemplary, the abutting surface 1221 includes both an inclined surface and a curved surface.

[0047] When the abutting surface 1221 includes an inclined surface, the slope (or gradient) at each position on the inclined surface is equal. In this way, when the slider 1211 slides on the abutting surface 1221, the rotation speed of the clamp mechanism 11 remains consistent, which is conducive to the stable disassembly of the touch screen and the main body of the electronic device.

[0048] When the abutment surface 1221 includes a curved surface, such as Figure 3As shown, the slopes of various positions on the abutment surface 1221 are not equal, so that when the slider 1211 slides on the abutment surface 1221, the rotation rate of the clamp mechanism 11 will change, so that the rotation speed of the clamp mechanism 11 can be adaptively adjusted according to the different stages of disassembly of the electronic device, thereby ensuring the success rate of disassembly of the electronic device.

[0049] Exemplarily, the curved surface includes: a first portion close to the hinge axis 20 and a second portion away from the hinge axis 20 , and the slope change rate of the first portion is greater than the slope change rate of the second portion.

[0050] It should be noted that the first part and the second part are both parts of the curved surface, and both are curved surfaces. The slope is the degree of inclination of a point on the curved surface relative to the horizontal direction, and the slope change rate is the degree of change from the slope of one point on the curved surface to the slope of another point.

[0051] For example, for the first part, the difference between the slope of the first point and the slope of the second point is the first difference; for the second part, the difference between the slope of the third point and the slope of the fourth point is the second difference; the spacing between the first point and the second point is equal to the spacing between the third point and the fourth point. In this case, the first difference is greater than the second difference.

[0052] In this arrangement, since the rotating follower 122 has a smaller thickness on the side away from the hinge shaft 20, the side of the rotating follower 122 away from the hinge shaft 20 is the starting point for the rotating follower 122 to rotate. By setting the slope change rate of the first part to be smaller, the speed of the rotating follower 122 when it is just rotated and lifted can be smaller, thereby avoiding the failure of the separation between the main body and the touch screen due to excessive force applied to the electronic device in the initial stage, which is conducive to improving the success rate of disassembly of the electronic device. In addition, the slope change rate of the second part is larger, which can make the rotation speed of the rotating follower 122 larger when the electronic device is about to be disassembled, thereby improving the disassembly rate of the electronic device.

[0053] In some embodiments, Figure 3 As shown, the slider 1211 includes a slider body 1200 and a rotating wheel 1201 rotatably disposed on the slider body 1200 , a driver 1212 is connected to the slider body 1200 and drives the slider body 1200 to move, and a rotating surface of the rotating wheel 1201 abuts against an abutting surface 1221 .

[0054] With this arrangement, there is sliding friction between the slider 1211 and the abutment surface 1221, which helps to reduce the friction between the two. In addition, the contact point between the rotating surface of the rotating wheel 1201 and the abutment surface 1221 is constantly changing, which can also reduce the heat generated during the friction between the two, thereby avoiding damage to the slider 1211 and the abutment surface 1221.

[0055] In some examples, the rotating wheel 1201 is rotatably disposed on the mounting seat of the slider body 1200 via a hinge shaft, thereby ensuring that the rotating wheel 1201 can stably rotate. In some examples, the driver 1212 can be a hydraulic telescopic mechanism or a linear motor, etc., so that the driver 1212 can directly drive the slider 1211 to perform linear motion.

[0056] In other examples, the driver 1212 may also be a rotary motor, which may be converted into linear motion through a cam mechanism, a connecting rod mechanism, or an eccentric wheel, and then connected to the slider body 1200 to enable the slider 1211 to perform linear motion.

[0057] In some examples, such as Figure 3 As shown, the rotating follower 122 and the clamp mechanism 11 can be connected by screws, so that the two are very convenient to disassemble and assemble.

[0058] In some embodiments, Figure 1 and Figure 2 As shown, a mounting hole 1101 is provided on the clamp mechanism 11 , and the mounting hole 1101 is configured to have a shape and size adapted to the main body of the electronic device, that is, the shape and size of the mounting hole 1101 are respectively adapted to the shape and size of the main body.

[0059] With this arrangement, the electronic device can be aligned with the mounting hole 1101, so that the electronic device can be quickly placed in the mounting hole 1101, which is beneficial for fixing the main body of the electronic device and improving the installation efficiency and disassembly efficiency of the electronic device.

[0060] Different mounting holes 1101 can be made according to electronic devices of different sizes. When electronic devices of other sizes need to be disassembled, only the clamp mechanism 11 needs to be replaced. The disassembly device 100 is very convenient for replacing the clamp mechanism 11, which is conducive to disassembling electronic devices of different sizes in batches, thereby improving the use flexibility of the disassembly device 100.

[0061] In some examples, the main body of the electronic device and the clamp mechanism 11 may be fixed by interference fit, and the main body is fixed by clipping the main body into the mounting hole 1101 .

[0062] In other examples, a telescopic member may be arranged at the position of the mounting hole 1101 of the clamp mechanism 11. After the main body of the electronic device is placed in the mounting hole 1101, the telescopic member is driven to extend and come into contact with the main body, thereby clamping and fixing the main body. After the electronic device is disassembled, the telescopic member is driven to retract to release the main body, thereby facilitating the recovery of the main body.

[0063] Of course, the specific implementation of the clamp mechanism 11 is not limited to the description in the above example. As long as it can clamp and fix the main body of the electronic device and release the main body after the electronic device is disassembled, it is within the scope of the embodiment of the present disclosure.

[0064] In some embodiments, the disassembly device 100 further includes a heating mechanism, which is fixed on the clamp mechanism 11 and located in the mounting hole 1101 .

[0065] With this arrangement, the heating mechanism can be used to heat the adhesive between the main body of the electronic device and the touch screen, thereby softening the adhesive and rendering it ineffective, thereby facilitating the disassembly and separation of the main body and the touch screen.

[0066] In some examples, the heating mechanism may be arranged around the mounting hole 1101 , which helps to fully and effectively heat the adhesive, thereby further improving the separation efficiency of the main body and the touch screen.

[0067] In other examples, the heating mechanism may be arranged partially around the mounting hole 1101, so that local heating around the electronic device can be achieved.

[0068] In some embodiments, the disassembly device 100 also includes a temperature control mechanism, which is electrically connected to the heating mechanism. The heating temperature of the heating mechanism can be controlled through the temperature control mechanism, which is conducive to more accurate temperature control and better disassembly of the electronic device.

[0069] In some embodiments, please refer to Figure 1 and Figure 2 The clamp mechanism 11 is also provided with a hollow portion 1102, which is located on a side of the mounting hole 1101 away from the hinge shaft 20, and the hollow portion 1102 is configured to allow a finger to be inserted.

[0070] Since fingers can be inserted into the hollow portion 1102, it is convenient for the operator to pull up the clamp mechanism 11 (pull it away from the shell 10) or close it (pull it down toward the shell 10) around its hinge axis 20, which makes it easy to manually inspect and repair the disassembly device.

[0071] In addition, since there is only an abutment effect between the rotating follower 122 and the slider 1211 without any connection relationship, it is convenient for the operator to smoothly pull up or close the clamp mechanism 11 without being affected by the driver 1212.

[0072] In some examples, the hollow portion 1102 is configured to allow multiple (eg, four) fingers to be inserted therein, which makes it easier for the operator to pull up or close the clamp mechanism 11 .

[0073] In some embodiments, Figure 3 As shown, the disassembly device 100 further includes an adsorption mechanism 13 , which is fixed on the housing 10 and located between the clamp mechanism 11 and the housing 10 , and is configured to adsorb a touch screen of the electronic device.

[0074] In this way, when the electronic device is placed on the disassembly device 100, the touch screen of the electronic device faces downward and is attached to the adsorption mechanism 13. The adsorption mechanism 13 is used to adsorb the touch screen, and the clamp mechanism 11 is used to fix the main body of the electronic device. By rotating the clamp mechanism 11, the touch screen and the main body can be separated.

[0075] Exemplarily, the adsorption mechanism 13 includes a plurality of vacuum suction cups. After the touch screen is attached to the vacuum suction cups, the air in the suction cup bodies is evacuated to fix the touch screen.

[0076] Exemplarily, the suction cup body is made of silicone material, which can improve the adsorption stability of the vacuum suction cup.

[0077] The disassembly device 100 described in the above embodiment has a compact and simple structure, occupies a small volume and area, is easy to operate, is convenient to use, and has a high efficiency in disassembling the electronic device.

[0078] The utility model names provided in the embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
