Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment processing, and in particular to a cutting device for separating an inner screen and an outer screen of a screen. Background Art

[0002] With the continuous development of electronic devices, curved screen electronic devices (such as curved screen mobile phones) are becoming more and more popular. The characteristic of curved screen electronic devices is that the edges of the screen are all set to be curved, so that the screen display area is larger while still ensuring that the curved screen electronic device is easy for users to hold. In addition, the curved screen electronic device has a fashionable and high-end appearance, a stronger sense of design, and is more beautiful.

[0003] However, there are also some problems with curved screen electronic devices: compared with traditional straight screen electronic devices, because the edge of the screen is set to be curved, when it is impacted, the force-bearing area of ​​the screen is smaller, which can easily cause the impact force to concentrate and damage the screen. This greatly increases the demand for repair of curved screen electronic devices. During repair, it is necessary to separate the adhesive layer between the damaged outer screen (such as the cover or touch panel) and the intact inner screen (such as the display module) of the curved screen electronic device, so as to separate the inner screen and the outer screen, and recycle the intact inner screen to avoid excessively increasing the user's repair costs.

[0004] In the prior art, a cutting device with a cutting line is often used to separate the inner screen from the outer screen by cutting the adhesive layer with a tensioned cutting line. However, due to the special shape of the screen of the curved screen electronic device, the shape of the cutting line does not match the shape of the screen; and the design of the cutting device provided by the prior art is only for straight screen electronic devices, and has not yet been designed for the special case of curved screen electronic devices. Therefore, it is difficult for the cutting device provided by the prior art to separate the inner and outer screens of the curved screen electronic device, the separation success rate is low, and the maintenance cost is high. Utility Model Content

[0005] The embodiment of the present application provides a cutting device for separating the inner screen and the outer screen of a screen, which solves the problems in the prior art that the cutting device is difficult to separate the inner and outer screens of a curved screen electronic device, has a low separation success rate, and has a high maintenance cost.

[0006] The embodiment of the present application provides a cutting device for separating the inner screen and the outer screen of a screen, comprising: a base, a stage, a wiring drive assembly, a guide assembly and a cutting line. The stage is arranged on the base and can rotate relative to the base around a first axis, and the stage is used to fix and install the screen to be separated. The wiring drive assembly includes a first winding part and a second winding part, and the first winding part and the second winding part are arranged at intervals in the first direction. The guide assembly includes a first guide part and a second guide part, and the first guide part and the second guide part are respectively arranged on both sides of the stage in the first direction. One end of the cutting line is wound around the first winding part, and the cutting line wound from the first winding part is sequentially connected to the first guide part and the second guide part, and the other end of the cutting line is wound around the second winding part.

[0007] Furthermore, each of the first guide portion and the second guide portion can be moved relative to the base in the second direction to adjust the extension direction of the cutting segment of the cutting line and the distance between the cutting segment and the stage in the second direction. The portion of the cutting line between the first guide portion and the second guide portion is the cutting segment, the extension direction of the cutting segment is parallel or inclined relative to the first direction, and the second direction is parallel to the direction of the first axis and perpendicular to the first direction.

[0008] By providing a first guide portion and a second guide portion that can move in the second direction relative to the base, the angle between the cutting segment of the cutting line and the first direction and the height of the cutting segment can be adjusted, so that the cutting segment can cut into the screen of the curved screen electronic device at a certain angle, and by continuously adjusting the angle and height of the cutting segment during cutting, the cutting path of the cutting segment in the entire cutting process matches the curvature of the screen itself (or can be understood as cutting along the shape of the screen), thereby completing the cutting of the adhesive layer without cutting the inner screen, thereby completing the separation of the inner and outer screens.

[0009] The above description is relatively abstract, so here we can also use an example of the operation of separating the inner and outer screens of a curved screen electronic device: First, place the screen of the curved screen electronic device on a stage (wherein the surface of the outer screen of the screen facing away from the inner screen is arranged toward the stage, and the surface of the inner screen facing away from the outer screen is arranged away from the stage), so as to fix it. Then, adjust the first guide part and the second guide part to have a height difference in the second direction, so that the cutting section of the cutting line is inclined relative to the screen (or it can be understood that the cutting section has an angle with the first direction). After each guide part is adjusted into place, rotate the screen until the surface of the outer screen facing the inner screen in one of the corners of the screen is tangent to the cutting section, and gradually adjust the height of the cutting section by adjusting each guide part, so that the cutting section begins to cut into the screen. After cutting in, by adjusting the cutting section angle and rotating the stage at the same time, the cutting section gradually cuts into the arc edge in the width direction of the screen (or it can be understood as the long side of the screen), and gradually cuts downward along the edge of the arc edge. When cutting to the bottom surface of the curved edge, the cutting segment can be adjusted to be parallel to the first direction, and continue to cut the straight area of ​​the screen by rotating the stage. After the straight area is cut, the stage is rotated until the cutting segment slides out along the other curved edge in the width direction of the screen (or can be understood as the other long side of the screen), and the inner and outer screens of the curved screen electronic device can be separated. Compared with the cutting equipment in the prior art, when the cutting equipment provided in the present application separates the inner and outer screens, the cutting path of the cutting segment can be consistent with the shape of the screen itself throughout the entire process, so it is not easy to cut the inner screen, thereby improving the separation success rate and reducing the maintenance cost of the curved screen electronic device.

[0010] In summary, the cutting equipment provided in the present application has low difficulty in separating the inner and outer screens of a curved screen electronic device, has a high separation success rate, and has low maintenance costs.

[0011] In some embodiments, each of the first guide portion and the second guide portion includes a guide wheel, and the guide wheel has a guide groove. The cutting line is arranged in the guide groove. On the one hand, by providing a guide wheel, the direction of the cutting line can be changed more smoothly. On the other hand, by providing a guide wheel in each guide portion, the cutting line can be divided into multiple sections, which is conducive to observing whether the cutting line is tensioned, and is also convenient for real-time adjustment of the cutting line to ensure that the cutting line is always in a tensioned state during cutting. At the same time, by providing a guide groove on the guide wheel, the movement of the cutting line in the second direction can also be limited to a certain extent, so that when it cuts the adhesive layer between the inner and outer screens in the screen and encounters resistance, it can still remain in the guide groove, thereby preventing the cutting line from sliding in the second direction and damaging the inner screen.

[0012] In some embodiments, each of the first guide portion and the second guide portion further includes a limiting portion, and the limiting portion itself forms a limiting slit. The limiting slit is configured to allow the cutting line to pass through, and to limit the cutting line located between the limiting slit and the guide groove to extend in a direction parallel to the first direction.

[0013] Here, it can be understood that: each guide portion is also provided with a limiting portion, and the limiting portion is formed with a limiting slit for the cutting line to pass through, and the part of the cutting line between the limiting slit and the guide groove is limited to be parallel to the first direction. By providing the limiting portion, it can be further ensured that the cutting line will not be displaced in the second direction when cutting the adhesive layer and encountering resistance (for example, the cutting line can be limited to slide out of the guide groove in the second direction), so that the cutting path of the cutting line is more controllable, and it always presents a predetermined angle in the second direction during cutting, thereby ensuring the cutting accuracy and cutting success rate.

[0014] In some embodiments, the limiting portion includes two rollers spaced apart in the second direction, and the gap between the two rollers constitutes a limiting slit. By setting the limiting portion as two rollers, and the gap between the two rollers constituting the limiting slit, when the cutting line moves along its extension direction, the rollers can be driven to rotate in the same direction, thereby reducing the friction between the cutting line and the rollers, and extending the life of the cutting line and the limiting portion.

[0015] In some embodiments, the guide wheel can rotate around its axis, each of the two rollers can rotate around its axis, and the axis of the guide wheel is perpendicular to the axis of each roller. The direction of the axis of the guide wheel is parallel to the second direction.

[0016] It can be understood here that: the guide wheel and the two rollers of the limiting part can rotate around their axes, so that when the cutting line moves in its extension direction, the guide wheel and the rollers can be driven to rotate together, thereby minimizing the friction between the cutting line and the components of the guide part.

[0017] In some embodiments, each of the first guide portion and the second guide portion is mounted on the base through a displacement adjustment assembly; wherein each displacement adjustment assembly comprises: a bracket and a slider. The bracket is mounted on the base, and a slide rail extending along the second direction is provided on the bracket. The slider is mounted with a corresponding guide portion, and is slidably connected to the slide rail along the second direction, so that the guide portion can move relative to the base in the second direction.

[0018] Here, it can be understood that: the guide part is slidably connected to the slide rail extending along the second direction on the bracket through the slider, so that it can slide relative to the base in the second direction. By providing the slide rail, on the one hand, each guide part can be adjusted to any height, and the adjustment freedom is high; on the other hand, the movement of each guide part can be more controllable, so that the cutting path of the cutting line is also more controllable.

[0019] In some embodiments, in each displacement adjustment assembly, the bracket includes a main body, a first extension portion, and a second extension portion, the main body extends along the second direction, the first extension portion and the second extension portion are arranged at a relative interval in the second direction, and are respectively connected to the two ends of the main body, the bracket is installed on the base through the first extension portion, and two slide rails are arranged on the bracket at intervals, one end of each slide rail is fixed to the first extension portion, and the other end is fixed to the second extension portion. Each displacement adjustment assembly also includes two elastic members and an adjustment component, the two elastic members are arranged corresponding to the two slide rails, each elastic member is sleeved outside the corresponding slide rail, and one end of the elastic member abuts against the first extension portion, and the other end abuts against the slider. The adjustment component passes through the second extension portion and is threadedly connected to the slider, so that the slider and the guide portion installed on the slider are driven to move relative to the base in the second direction through the rotation of the adjustment component.

[0020] Here it can be understood that: two slide rails are arranged at intervals on the bracket, and an elastic member is arranged on the outer sleeve of each slide rail. One end of the elastic member abuts against the first extension part, and the other end abuts against the slider, so that the guide part installed on the slider can move in the second direction by compressing or releasing the elastic member. Each displacement adjustment assembly is also provided with an adjustment component, which passes through the second extension part and is threadedly connected to the slider, and compresses or releases the elastic member through the adjustment component. By setting the adjustment component as a threaded connection, the adjustment accuracy when adjusting the height of the guide part can be further improved, and it is more convenient to accurately adjust the position of the cutting section when separating the inner and outer screens.

[0021] In some embodiments, the wire routing drive assembly includes a winding rod that can rotate around its axis, and the winding rod and the stage are spaced apart in a third direction. The third direction is perpendicular to the first direction and the second direction. One end of the winding rod constitutes a first winding portion, and the other end constitutes a second winding portion, and the winding direction of the cutting wire in the first winding portion is opposite to the winding direction of the cutting wire in the second winding portion.

[0022] Here, it can be understood that the wire routing drive assembly includes a winding rod, and the two ends of the winding rod respectively constitute two winding parts. When the winding rod rotates in any direction (for example, clockwise or counterclockwise), the two ends of the cutting wire wound on the first winding part and the second winding part always have one end feeding the wire and the other end releasing the wire, thereby ensuring that the length of the cutting wire outside the two winding parts is constant. The wire routing drive assembly designed in this way occupies a small space, has a simple structure, and is easy to ensure that the length of the cutting wire remains unchanged.

[0023] In some embodiments, the direction of the axis of the winding rod is parallel to the first direction, so that the straight line where the first winding portion and the second winding portion are cut is approximately parallel to the cutting section of the cutting wire, and the projection of the cutting wire on a plane perpendicular to the second direction forms a trapezoid or a rectangle, so that the cutting wire is easier to tension.

[0024] In some embodiments, the routing drive assembly further includes a driving component, which is in transmission connection with the winding rod to drive the winding rod to rotate. By further providing a driving component, the winding rod can be driven to rotate, so that when cutting the adhesive layer, the cutting line can saw through the adhesive layer instead of cutting the adhesive layer, thereby reducing the resistance during cutting. On the one hand, it can make the cutting smoother, and on the other hand, it can also avoid the displacement of the cutting line in the second direction due to excessive resistance, thereby damaging the intact inner screen. It is also helpful to extend the service life of the cutting line.

[0025] In some embodiments, the routing drive assembly also includes a first mounting seat, a first sliding rod and a second sliding rod. The driving component and the winding rod are mounted on the first mounting seat. The first sliding rod and the second sliding rod are fixedly mounted on the base and extend along a third direction on a plane perpendicular to the second direction, and the first mounting seat is slidably connected to the first sliding rod and the second sliding rod along the third direction, so that the driving component and the winding rod can move relative to the base along the third direction. By arranging the driving component and the winding rod on the first mounting seat that can move in the third direction, when the cutting line is relaxed due to resistance to cutting the adhesive layer, the cutting line can be tightened by moving the driving component and the winding rod as a whole in the third direction, so that the cutting line returns to a tensioned state. It is convenient to adjust and easy to operate.

[0026] In some embodiments, the routing drive assembly further includes a driving rod and a connecting block, the connecting block is fixedly connected to the first mounting seat, and the driving rod is threadedly connected to the connecting block, so that the connecting block and the first mounting seat fixedly connected to the connecting block are driven to move relative to the base in the third direction through the rotation of the driving rod. By providing the driving rod and the connecting block with threaded connection, the position of the first mounting seat in the third direction can be adjusted more accurately.

[0027] In some embodiments, the cutting device further includes a worm gear mechanism, which includes a worm wheel and a worm connected in a transmission manner, wherein the extension direction of the worm is perpendicular to the first axis, and at least one end of the worm extends outside the stage, and the worm wheel is in transmission connection with the stage, so that the worm wheel can drive the stage to rotate around the first axis through the worm. First, the worm extending outside the stage is convenient for the user to operate without interfering with the stage. Secondly, the worm gear mechanism has a simple structure and is easy to operate, which is also conducive to improving the accuracy of rotating the stage, allowing the user to set the stage angle more accurately and improve the success rate of cutting.

[0028] In some embodiments, the cutting device further comprises a second mounting seat, a third sliding rod and a fourth sliding rod. The worm gear mechanism is mounted on the second mounting seat, and the stage is connected to the second mounting seat for rotation around the first axis. The third sliding rod and the fourth sliding rod are mounted on the base and extend along a third direction on a plane perpendicular to the second direction, and the second mounting seat is connected to the third sliding rod and the fourth sliding rod for sliding along the third direction, so that the stage and the worm gear mechanism can move relative to the base along the third direction.

[0029] It can be understood here that: the worktable is arranged on the second mounting seat, and the second mounting seat is slidably connected to the third sliding rod and the fourth sliding rod extending along the third direction, so that the worktable can also slide in the third direction, so that the large area of ​​the adhesive layer in the straight plate area can be cut quickly and repeatedly, thereby improving the cutting efficiency.

[0030] In some embodiments, when the cutting device includes a first sliding rod and a second sliding rod, the axes of the first sliding rod and the third sliding rod coincide and connect, and the axes of the second sliding rod and the fourth sliding rod coincide and connect, so that the cutting device has a compact structure and occupies a small area.

[0031] In some embodiments, the first sliding rod and the third sliding rod are integrally formed into an integrated structure. The second sliding rod and the fourth sliding rod are integrally formed into an integrated structure. This reduces the number of parts, simplifies the structure of the cutting device, and reduces the manufacturing cost of the cutting device. BRIEF DESCRIPTION OF THE DRAWINGS

The present application does not make specific limitations on this.

[0069] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0070] The cutting equipment in the prior art is difficult to separate the inner and outer screens of the screen of the curved screen electronic device, the separation success rate is low, and the maintenance cost is high. In view of the above problems, the embodiment of the present application provides a cutting device for separating the inner and outer screens of the screen, which is less difficult to separate the inner and outer screens of the screen (especially the curved screen), has a high separation success rate, and a low maintenance cost.

[0071] It should be noted that the method of separating the inner and outer screens of the screen using a cutting device is to cut the adhesive layer between the inner and outer screens of the screen to separate the damaged outer screen from the intact inner screen, and recycle the inner screen for reuse.

[0072] The above screen is applied to electronic devices. For example, the electronic device may be a mobile phone, a laptop computer, a digital camera, a vehicle-mounted device, or other electronic product with a screen. In an embodiment of the present application, the electronic device may include a screen and a body that are fixedly connected. The following will provide an exemplary description of the structures of the two screens in conjunction with the accompanying drawings.

[0073] See also Figure 1a-Figure 2 , Figure 1a A schematic diagram of the structure of a screen; Figure 1b for Figure 1a A magnified image of area A; Figure 1c A schematic diagram of the structure of a screen from another perspective; Figure 2 A schematic diagram of the structure of another screen.

[0074] like Figure 1a-Figure 1c As shown, the screen 7 includes an inner screen 71, an adhesive layer 73 and an outer screen 72 stacked along the thickness direction thereof. The inner screen 71 is bonded to the outer screen 72 through the adhesive layer 73.

[0075] The inner screen 71 is used to display images and can be a display module, for example, a liquid crystal display (LCD), an organic light emitting diode (OLED) display, etc., which is not limited in this application. The outer screen 72 is used to protect the inner screen 71 and can be a glass cover, a touch panel, etc., which is not limited in this application.

[0076] In the embodiment of the present application, the adhesive layer 73 may be an optically clear adhesive (OCA). In some other embodiments, the adhesive layer 73 may also be other glues, as long as the inner screen 71 and the outer screen 72 of the screen 7 can be bonded together, and the present application does not limit this.

[0077] It should be noted that the type of the screen 7 is not limited, for example, it can be a curved screen (see Figure 1a to Figure 1c ) or flat screen (see Figure 2 ). In one example, if Figure 1a to Figure 1c As shown, the screen 7 is a curved screen having a straight plate area 7B and two arc-shaped edges 7A connected to the straight plate area 7B on both sides along the width direction thereof.

[0078] During the specific repair, the outer screen 72 of the screen 7 is damaged, while the inner screen 71 is intact, so it is necessary to cut the adhesive layer 73 to separate the inner screen 71 from the outer screen 72, and recycle the intact inner screen 71 to avoid excessive increase in user costs. When cutting, it is necessary to start from one curved edge 7A of the screen 7, and repeatedly cut the adhesive layer 73 of the straight plate area 7B of the screen 7, and finally cut out from the other curved edge 7A of the screen 7 to complete the separation of the inner screen 71 and the outer screen 72. The above cutting process can be specifically referred to Figure 1a The cutting direction is understood.

[0079] It should be noted that the following description uses the screen 70 as an example of a curved screen, and uses a cutting device to separate the inner and outer screens of the screen 70 because the curved screen is more difficult to separate, and does not mean that the cutting device provided in this application is only applicable to separating the inner and outer screens of a curved screen. Figure 2 As shown, for example, the screen 70 may also be a flat screen, and the separation process is the same as the process of cutting the straight area 7B in the curved screen, so it is not repeated here. The entire area of ​​the flat screen can be understood as the straight area.

[0080] The above briefly describes the structure of the screen and the working principle of separating the inner and outer screens of the screen. The following text will focus on the specific structure of the cutting equipment and the specific steps of using the cutting equipment to cut the adhesive layer to separate the inner and outer screens of the screen in combination with the accompanying drawings.

[0081] See also Figure 3 , Figure 3 This is a schematic diagram of the structure of the cutting device according to an embodiment of the present application.

[0082] like Figure 3 As shown, combined with Figure 1a-Figure 2 It is understood that the present application provides a cutting device 100, including: a base 6, a stage 1, a routing drive assembly 2, a guide assembly 3 and a cutting line 4. The stage 1 is arranged on the base 6 and can rotate relative to the base 6 around the first axis 111A, and the stage 1 is used to fix the screen 7 to be separated. The routing drive assembly 2 includes a first winding portion 21A and a second winding portion 21B, and the first winding portion 21A and the second winding portion 21B are arranged at intervals in the first direction x. The guide assembly 3 includes a first guide portion 3A and a second guide portion 3B, and the first guide portion 3A and the second guide portion 3B are respectively arranged on both sides of the stage 1 in the first direction x. One end of the cutting line 4 is wound around the first winding portion 21A, and the cutting line 4 wound from the first winding portion 21A is sequentially connected to the first guide portion 3A and the second guide portion 3B, and the other end of the cutting line 4 is wound around the second winding portion 21B.

[0083] Furthermore, each of the first guide portion 3A and the second guide portion 3B can be moved relative to the base 6 in the second direction z to adjust the extension direction of the cutting segment 41 of the cutting line 4 and the distance between the cutting segment 41 and the stage 1 in the second direction z. The portion of the cutting line 4 located between the first guide portion 3A and the second guide portion 3B is the cutting segment 41, and the extension direction of the cutting segment 41 is parallel to or inclined relative to the first direction x, and the second direction z is parallel to the direction of the first axis 111A and is perpendicular to the first direction x.

[0084] Here, it can be understood that the cutting wire 4 is wound around the first winding part 21A, and is wound out from the first winding part 21A, and then successively passes around the first guide part 3A and the second guide part 3B and is wound around the second winding part 21B. It should be noted that the portion of the cutting wire 4 located between the first guide part 3A and the second guide part 3B is called the cutting segment 41, which is used to cut the adhesive layer 73. It should be emphasized that the cutting segment 41 mentioned here is not a fixed part of the cutting wire 4, but refers to the portion of the cutting wire 4 used to cut the adhesive layer 73, and the cutting segment 41 and the portion of the cutting wire 4 wound around the first winding part 21A and the second winding part 21B can be converted into each other.

[0085] It should be noted that the first direction x described here can be understood as any direction parallel to the mounting surface 10 of the stage 1, wherein the mounting surface 10 of the stage 1 is: the surface of the stage 1 for mounting the screen 7, or it can be understood that the first direction x is parallel to the front and back of the straight panel area 7B in the screen 7 (which should be understood as the screen 7 mounted on the stage 1). Among them, the surface of the inner screen 71 facing away from the outer screen 72 constitutes the back of the screen 7, and the surface of the outer screen 72 facing away from the inner screen 71 constitutes the front of the screen 7. It can be understood by those skilled in the art that when the screen 7 is a straight screen, the entire screen 7 is the straight panel area 7B. When the screen 7 is a curved screen, the other areas of the curved screen except the arc edge 7A are the straight panel area 7B.

[0086] The first direction x described here may also be parallel to a plane perpendicular to the height direction of the base 6 , for example, it may be parallel to the width direction of the base 6 , or it may be parallel to the length direction of the base 6 , and the present application does not impose any limitation on this.

[0087] The extension direction of the cutting segment 41 mentioned above is inclined relative to the first direction x, or it can be understood that the extension direction of the cutting segment 41 is inclined relative to the mounting surface 10 of the stage 1, or it can be understood that it is inclined relative to the front or back side of the screen 7 (it should be understood that the screen 7 is mounted on the stage 1), and the present application does not make any limitation here.

[0088] The second direction z can be understood as being perpendicular to the mounting surface 10 of the stage 1, or can be understood as being parallel to the thickness direction of the straight plate area 7B in the screen 7 (which should be understood as the screen 7 mounted on the stage 1). The second direction z described here can also be parallel to the height direction of the base 6. This application does not limit this.

[0089] For the convenience of unified description, the third direction y mentioned below is defined here. The third direction y is perpendicular to the first direction x and the second direction z. Exemplarily, the third direction y can be the length direction of the base 6, and the present application does not limit it here either.

[0090] In the present application, by providing a first guide portion 3A and a second guide portion 3B that can move relative to the base 6 in the second direction z, the angle between the cutting segment 41 of the cutting line 4 and the first direction x and the height of the cutting segment 41 can be adjusted, so that the cutting segment 41 can cut into the screen 7 (for example, a curved screen) at a certain angle, and by continuously adjusting the angle and height of the cutting segment 41 during cutting, the cutting path of the cutting segment 41 in the entire cutting process matches the curvature of the screen 7 itself (or can be understood as cutting along the shape of the screen 7), thereby completing the cutting of the adhesive layer 73 without cutting the inner screen 71, thereby completing the separation of the inner and outer screens.

[0091] To sum up, the cutting device 100 provided in the present application has low difficulty in separating the inner screen and the outer screen of the curved screen, high separation success rate and low maintenance cost, and when separating the inner screen and the outer screen of the straight screen, the cutting method can also be more flexible.

[0092] The above is an explanation of the basic principle of the cutting device 100 of the present application. The specific structure of each component of the cutting device 100 of the present application and its possible implementation methods will be explained below in conjunction with the drawings.

[0093] First, if Figure 3 As shown, the structure of the first guide portion 3A and the second guide portion 3B in the present application is described. It should be noted that the specific structure of the first guide portion 3A and the second guide portion 3B is not limited, and the structure of each guide portion 30 in the first guide portion 3A and the second guide portion 3B may be the same or different. In one example, the first guide portion 3A and the second guide portion 3B are arranged relative to each other and symmetrically. In the following, the specific structure of the guide portion 30 will be illustrated by taking the first guide portion 3A as an example in conjunction with the accompanying drawings. It can be understood by those skilled in the art that the second guide portion 3B may also adopt the structure described below, which will not be repeated here.

[0094] See also Figure 4-Figure 6 , Figure 4 This is a schematic diagram of the structure of the guide part in the cutting device of the embodiment of the present application; Figure 5 This is a schematic diagram of the structure of the displacement adjustment component in the cutting device of the embodiment of the present application; Figure 6 This is a schematic diagram of the matching structure of the guide part and the displacement adjustment component in the cutting device of the embodiment of the present application.

[0095] like Figure 4 As shown, combined with Figure 1a-Figure 3 It is understood that, in one embodiment, each guide portion 30 in the first guide portion 3A and the second guide portion 3B includes a guide wheel 31, and the guide wheel 31 has a guide groove 31A. The cutting line 4 is arranged in the guide groove 31A. On the one hand, by providing the guide wheel 31, the direction of the cutting line 4 can be changed relatively smoothly. On the other hand, by providing the guide wheel 31 in each guide portion, the cutting line 4 can be divided into multiple sections, which is conducive to observing whether the cutting line 4 is tensioned, and is also convenient for real-time adjustment of the cutting line 4 to ensure that the cutting line 4 is always in a tensioned state during cutting. At the same time, by providing the guide groove 31A on the guide wheel 31, the movement of the cutting line 4 in the second direction z can also be limited to a certain extent, so that it can still remain in the guide groove 31A when cutting the adhesive layer 73 and encountering resistance, thereby preventing the cutting line 4 from sliding in the second direction z and damaging the inner screen 71.

[0096] Those skilled in the art will appreciate that the specific structure of the guide portion 30 is not limited as long as it can guide the cutting line 4. For example, in another alternative embodiment, the guide portion 30 may also be provided with a rectangular guide column structure, which is not limited in the present application.

[0097] The above is a description of possible structures used for guidance in the guide part 30. A limiting structure may be further provided in the guide part 30 to improve the running stability of the cutting line 4 when it is cut and encounters resistance, so that the running trajectory of the cutting line is more controllable, thereby further improving the success rate of separating the inner and outer screens of the electronic device.

[0098] For example, Figure 4 As shown, combined with Figure 3 It is understood that, in one embodiment, each guide portion 30 in the first guide portion 3A and the second guide portion 3B further includes a limiting portion 32, and the limiting portion 32 itself is formed with a limiting slit 322. The limiting slit 322 is configured to allow the cutting line 4 to pass through, and to limit the cutting line 4 between the limiting slit 322 and the guide groove 31A to extend in a direction parallel to the first direction x. It may be understood here that each guide portion 30 is also provided with a limiting portion 32, and the limiting portion 32 is formed with a limiting slit 322, so that the cutting line 4 passes through, and to limit the portion of the cutting line 4 between the limiting slit 322 and the guide groove 31A to be parallel to the first direction x.

[0099] By providing the limiting portion 32, it can be further ensured that the cutting line 4 cuts the adhesive layer 73 (see Figure 1a to Figure 2 ) and will not be displaced in the second direction z when encountering resistance (for example, the cutting line 4 can be limited to slide out of the guide groove 31A in the second direction z), thereby making the cutting path of the cutting line 4 more controllable, and always presenting a predetermined angle in the second direction z during cutting, thereby ensuring the cutting accuracy and cutting success rate.

[0100] It should be noted that the parallelism described here is not absolute parallelism. As mentioned above, the approximate parallelism caused by processing errors and assembly errors (for example, the extension direction of the cutting line 4 between the limiting seam 322 and the guide groove 31A is at an angle of 2° to the first direction x) is also within the scope of the mutual parallelism described in this application, and this application does not make any specific limitations here.

[0101] It should be noted that the specific structure of the limiting portion 32 is not limited here.

[0102] like Figure 4As shown, in one embodiment, the limiting portion 32 includes two rollers 321 spaced apart in the second direction z, and the gap between the two rollers 321 constitutes a limiting slit 322. By setting the limiting portion 32 as two rollers 321, and the gap between the two rollers 321 constituting the limiting slit 322, when the cutting line 4 moves along its extension direction, the rollers 321 can be driven to rotate in the same direction, thereby reducing the friction between the cutting line 4 and the rollers 321, and extending the service life of the cutting line 4 and the limiting portion 32.

[0103] In another alternative embodiment, the limiting portion 32 may also be a limiting plate extending in the second direction z, and a limiting slit 322 is formed on the limiting plate, and the present application does not make any limitation thereto.

[0104] like Figure 4 As shown, further, the guide wheel 31 can rotate around its axis, and each of the two rollers 321 can rotate around its axis, and the axis of the guide wheel 31 is perpendicular to the axis of each roller 321. Among them, the direction of the axis of the guide wheel 31 is parallel to the second direction z. Here, it can be understood that: the guide wheel 31 and the two rollers 321 of the limiting part 32 can rotate around their axes, so that when the cutting line 4 moves toward its extension direction, the guide wheel 31 and the roller 321 can be driven to rotate together, thereby minimizing the friction between the cutting line 4 and the components of the guide part 30.

[0105] The above is an explanation of the specific structure of the guide portion 30 , and the connection relationship between the guide portion 30 and other components will be explained below.

[0106] It should be noted that the relationship between each guide part 30 and the base 6 is not limited. For example, each guide part 30 can be installed on the base 6 (directly or indirectly), or can be installed on the base 6 separately, but can be fixed to other objects (such as the ground) instead of being installed on the base 6. This application does not limit this.

[0107] like Figure 5-Figure 6 As shown, combined with Figure 4 It is understood that, in one embodiment, each guide portion 30 of the first guide portion 3A and the second guide portion 3B can be mounted on the base 6 via a displacement adjustment assembly 33, respectively, so that the cutting device 100 is more compact and convenient to transport as a whole.

[0108] The specific structure of the displacement adjustment assembly 33 is not limited. In one example, each displacement adjustment assembly 33 includes a bracket 34 and a slider 35. The bracket 34 is mounted on (in one example, fixedly and detachably connected to) the base 6, and a slide rail 344 extending along the second direction z is provided on the bracket 34. The slider 35 is mounted with a corresponding guide portion 30, and is slidably connected to the slide rail 344 along the second direction z, so that the guide portion 30 can move relative to the base 6 in the second direction z.

[0109] Here, it can be understood that: the guide part 30 is slidably connected to the slide rail 344 extending along the second direction z on the bracket 34 through the slider 35, so that it can slide relative to the base 6 in the second direction z. By providing the slide rail 344, on the one hand, each guide part 30 can be adjusted to any height, and the adjustment freedom is high; on the other hand, the movement of each guide part 30 can be more controllable, so that the cutting path of the cutting segment 41 of the cutting line 4 is also more controllable.

[0110] The specific structure of the bracket 34 is not limited. Figure 5-Figure 6 As shown, combined with Figure 3 It is understood that in one embodiment, in each displacement adjustment assembly 33, the bracket 34 includes a main body 341, a first extension 342 and a second extension 343, the main body 341 extends along the second direction z, the first extension 342 and the second extension 343 are arranged at intervals relative to each other in the second direction z, and are respectively connected to the two ends of the main body 341, the bracket 34 is installed on the base 6 through the first extension 342, and two slide rails 344 are arranged at intervals on the bracket 34, one end of each slide rail 344 is fixed to the first extension 342, and the other end is fixed to the second extension 343. Each displacement adjustment assembly 33 also includes two elastic members 345, the two elastic members 345 are arranged corresponding to the two slide rails 344, each elastic member 345 is sleeved outside the corresponding slide rail 344, and one end of the elastic member 345 abuts against the first extension 342, and the other end abuts against the slider 35. The adjusting component 36 passes through the second extending portion 343 and is threadedly connected to the slider 35 , so that the slider 35 and the guide portion 30 mounted on the slider 35 can be driven to move relative to the base 6 in the second direction z through the rotation of the adjusting component 36 .

[0111] Here, it may be understood that: the slide rail 344 specifically includes two slide rails 344 arranged at intervals, and each slide rail 344 is provided with an elastic member 345 on its outer sleeve. One end of the elastic member 345 abuts against the first extension portion 342, and the other end abuts against the slider 35, so that the guide portion 30 installed on the slider 35 can move in the second direction z by compressing or releasing the elastic member 345. Each displacement adjustment assembly 33 is also provided with an adjustment component 36, which passes through the second extension portion 343 and is threadedly connected to the slider 35, and compresses or releases the elastic member 345 through the adjustment component 36. By setting the adjustment component 36 as a threaded connection, the adjustment accuracy when adjusting the height of the guide portion 30 can be further improved, and it is more convenient to accurately adjust the position of the cutting segment 41 of the cutting line 4 when separating the inner and outer screens.

[0112] The above is a description of the specific structure of the guide part and the connection method with other components, taking the first guide part as an example. The following will describe the wiring drive assembly in conjunction with the accompanying drawings.

[0113] See also Figure 7-Figure 9 , Figure 7 This is a schematic diagram of the matching structure of the driving component and the winding rod in the cutting device of the embodiment of the present application; Figure 8 This is a schematic diagram of the structure of the wire routing drive component in the cutting device of the embodiment of the present application; Fig. 9 This is a schematic diagram of the matching structure of the first sliding rod, the second sliding rod, the driving rod, the connecting block and the sliding block in the cutting device according to an embodiment of the present application.

[0114] It should be noted that the specific structure of the routing drive component 2 is not limited. Moreover, the relative positional relationship between the first winding portion 21A and the second winding portion 21B in the routing drive component 2 is not limited, and the first winding portion 21A and the second winding portion 21B can adopt an integrated structure or a split structure (or it can be understood that the first winding portion 21A and the second winding portion 21B can rotate independently, the axes of rotation are different axes, and the directions of the axes are not limited).

[0115] like Figure 7-Figure 9 As shown, combined with Figure 3 It is understood that in one embodiment, the wire routing drive assembly 2 includes a winding rod 21 that can rotate around its axis, and the winding rod 21 is spaced apart from the stage 1 in the third direction y. The third direction y is perpendicular to the first direction x and the second direction z. Among them, one end of the winding rod 21 constitutes a first winding portion 21A, and the other end constitutes a second winding portion 21B, and the winding direction of the cutting wire 4 in the first winding portion 21A is opposite to the winding direction of the cutting wire 4 in the second winding portion 21B.

[0116] Here, it can be understood that the wire-walking drive assembly 2 includes a winding rod 21, and the two ends of the winding rod 21 respectively constitute two winding parts. When the winding rod 21 rotates in any direction (for example, clockwise or counterclockwise), the two ends of the cutting wire 4 wound on the first winding part 21A and the second winding part 21B always have one end feeding the wire and the other end releasing the wire, thereby ensuring that the length of the cutting wire 4 outside the two winding parts is constant. The wire-walking drive assembly 2 designed in this way occupies a small space, has a simple structure, and is easy to ensure that the length of the cutting wire 4 remains unchanged.

[0117] It should be noted that the winding directions described here are opposite, and the main purpose is to ensure that there is always one winding part for outputting wire and one winding part for inputting wire in the first winding part 21A and the second winding part 21B, so that the length of the cutting wire 4 outside the first winding part 21A and the second winding part 21B is constant, so the specific winding direction is not limited. Exemplarily, in one embodiment, the first winding part 21A is wound clockwise and the second winding part 21B is wound counterclockwise. In another alternative embodiment, the first winding part 21A is wound counterclockwise and the second winding part 21B is wound clockwise, and this application does not limit this.

[0118] Further, such as Figure 7 As shown, combined with Figure 3 It is understood that the direction of the axis of the winding rod 21 is parallel to the first direction x. Thus, the relative positions of the first winding portion 21A and the second winding portion 21B are approximately parallel to the position of the cutting segment 41 of the cutting line 4, and the projection of the cutting line 4 on the plane perpendicular to the second direction z forms a trapezoid or rectangle, so that the cutting line 4 is easier to tension. In another alternative embodiment, the direction of the axis of the winding rod 21 may not be parallel to the first direction x (for example, it is at an angle to the first direction x). This application is not limited here.

[0119] The above is a structural description of the winding rod and related components in the routing drive assembly. In order to make the cutting of the adhesive layer more efficient and the cutting smoother, a driving component can also be provided to make the cutting of the cutting section smoother.

[0120] like Figure 7-Figure 9 As shown, combined with Figure 1a-Figure 3It is understood that in one embodiment, the routing drive assembly 2 also includes a driving component 22, and the driving component 22 is connected to the winding rod 21 in a transmission manner to drive the winding rod 21 to rotate. By further providing a driving component 22, the winding rod 21 can be driven to rotate, so that when cutting the adhesive layer 73 of the screen 7, the cutting segment 41 of the cutting line 4 can saw off the adhesive layer 73 instead of cutting the adhesive layer 73, thereby reducing the resistance during cutting. Therefore, on the one hand, it can make the cutting smoother, and on the other hand, it can also avoid the displacement of the cutting segment 41 of the cutting line 4 in the second direction z due to excessive resistance, thereby damaging the intact inner screen 71. It is also helpful to extend the service life of the cutting line 4.

[0121] Those skilled in the art will appreciate that the specific structure and driving method of the driving component 22 described herein are not limited.

[0122] In one embodiment, if Figure 7 As shown, the driving component 22 can be a motor, and drives the winding rod 21 to rotate through a belt. In another alternative embodiment, the motor can also directly drive the winding rod 21 to rotate (or it can be understood that the output end of the motor is directly connected to the winding rod 21 to drive it to rotate).

[0123] Furthermore, the driving component 22 can also be specifically a speed-adjustable motor, such as an electromagnetic speed-adjustable motor or a variable frequency motor. During cutting, the speed of the winding rod 21 can be adjusted by adjusting the speed of the driving component 22, thereby adjusting the cutting speed to make it work at a suitable efficiency. In another alternative embodiment, the driving component 22 can also be a non-speed-adjustable motor to reduce costs, and this application is not limited here.

[0124] It should be noted that the rotation described here is not limited to rotation in a fixed direction. In actual operation, the driving component 22 rotates clockwise and counterclockwise alternately, so that the cutting wire 4 always remains partially wound around the first winding portion 21A and partially wound around the second winding portion 21B.

[0125] Furthermore, the wire routing drive assembly 2 may also be provided with a sliding structure so that the winding rod 21 can slide in the third direction y, thereby adjusting the cutting line 4 in real time so that the cutting line 4 is in a tensioned state.

[0126] like Figure 8-Figure 9 As shown, combined with Figure 3It is understood that, illustratively, in one embodiment, the routing drive assembly 2 further includes a first mounting seat 55, a first sliding rod 51 and a second sliding rod 52. The driving component 22 and the winding rod 21 are mounted on the first mounting seat 55. The first sliding rod 51 and the second sliding rod 52 are fixedly mounted on the base 6 and extend along the third direction y on a plane perpendicular to the second direction z, and the first mounting seat 55 is slidably connected to the first sliding rod 51 and the second sliding rod 52 along the third direction y, so that the driving component 22 and the winding rod 21 can move along the third direction y relative to the base 6. By arranging the driving component 22 and the winding rod 21 on the first mounting seat 55 that can move in the third direction y, when the cutting line 4 is relaxed due to resistance to cutting the adhesive layer, the cutting line 4 can be tightened by moving the driving component 22 and the winding rod 21 as a whole in the third direction y, so that the cutting line 4 returns to a tensioned state. It is convenient to adjust and easy to operate.

[0127] It should be noted that the method of driving the first mounting seat 55 is not limited.

[0128] In one embodiment, the wiring drive assembly 2 further includes a driving rod 57A and a connecting block 58A, wherein the connecting block 58A is fixedly connected to the first mounting seat 55, and the driving rod 57A is threadedly connected to the connecting block 58A, so that the connecting block 58A and the first mounting seat 55 fixedly connected to the connecting block 58A are driven to move relative to the base 6 in the third direction y through the rotation of the driving rod 57A. By providing the driving rod 57A and the connecting block 58A with threaded connection, the position of the first mounting seat 55 in the third direction y can be adjusted more accurately.

[0129] In another alternative embodiment, the position of the first mounting seat 55 may be adjusted by directly pushing the first mounting seat 55 without providing a displacement adjustment component, and the present application does not impose any limitation thereto.

[0130] Those skilled in the art will appreciate that the specific connection method between the first mounting seat and the first sliding rod and the second sliding rod is also not limited.

[0131] like Figure 8-Figure 9 As shown, in one embodiment, four sliding blocks 59A are provided on the surface of the first mounting seat 55 facing the first sliding rod 51 and the second sliding rod 52. The sliding blocks 59A are grouped in pairs, and each group is respectively sleeved on the first sliding rod 51 and the second sliding rod 52, so that the first mounting seat 55 can slide along the extension direction of the first sliding rod 51 and the second sliding rod 52 through the sliding blocks 59A.

[0132] The above is a description of the specific structure of each component of the wiring drive assembly in this application. The following is a description of the stage and related structures.

[0133] See also Figure 10-12a, Fig.10 This is a schematic diagram of the matching structure of the stage, the worm gear mechanism and the second mounting seat in the cutting device of the embodiment of the present application; Fig.11 This is a schematic diagram of the structure of the worm gear mechanism in the cutting device of the embodiment of the present application; Fig.12a It is a schematic diagram of the matching structure of the stage, the worm gear mechanism, the second mounting seat, the third sliding rod and the fourth sliding rod in the cutting device of the embodiment of the present application; Figure 12b It is a schematic diagram of the matching structure of the third sliding rod, the fourth sliding rod, the additional driving rod, the additional connecting block and the additional sliding block in the cutting device of the embodiment of the present application.

[0134] like Figure 10-11 As shown, combined with Figure 3 It is understood that in one embodiment, the cutting device 100 also includes a worm gear mechanism 11, which includes a worm wheel 111 and a worm 112 that are transmission-connected, the extension direction of the worm 112 is perpendicular to the first axis 111A, and at least one end of the worm 112 extends outside the worktable 1, and the worm wheel 111 is transmission-connected to the worktable 1 so that the worm wheel 111 can be driven by the worm 112 to drive the worktable 1 to rotate around the first axis 111A.

[0135] It should be noted that the term "extending outside the stage 1" specifically refers to the projection of the worm 112 on a plane perpendicular to the second direction z extending outside the projection of the stage 1 on the same plane. Thus, firstly, the worm 112 extending outside the stage 1 is convenient for the user to operate without interfering with the stage 1. Secondly, the worm gear mechanism 11 has a simple structure and is easy to operate, which is also conducive to improving the accuracy of rotating the stage 1, allowing the user to set the angle of the stage 1 more accurately and improve the success rate of cutting.

[0136] Those skilled in the art will appreciate that the worm gear mechanism 11 may not be provided in the cutting device 100 , and this application does not impose any limitation on this.

[0137] Furthermore, the cutting device 100 may also be provided with a component that allows the stage 1 to move in the third direction y to improve the cutting efficiency.

[0138] like Fig.12a As shown, combined with Figure 1a-Figure 3 and Figure 10-11It is understood that in one embodiment, the cutting device 100 further includes a second mounting seat 56, a third sliding rod 53, and a fourth sliding rod 54. The worm gear mechanism 11 is mounted on the second mounting seat 56, and the stage 1 is rotatably connected to the second mounting seat 56 around the first axis 111A. The third sliding rod 53 and the fourth sliding rod 54 are mounted on (fixedly connected to) the base 6 and extend along the third direction y on a plane perpendicular to the second direction z, and the second mounting seat 56 is slidably connected to the third sliding rod 53 and the fourth sliding rod 54 along the third direction y, so that the stage 1 and the worm gear mechanism 11 can move relative to the base 6 along the third direction y.

[0139] It can be understood here that: the worktable 1 is arranged on the second mounting seat 56, and the second mounting seat 56 is slidably connected to the third sliding rod 53 and the fourth sliding rod 54 extending along the third direction y, so that the worktable 1 can also slide in the third direction y, so that the large area of ​​the adhesive layer 73 in the straight plate area 7B of the screen 7 can be cut quickly and repeatedly, thereby improving the cutting efficiency.

[0140] It should be noted that the specific driving method of the second mounting seat 56 is also not limited. Figure 12a-12b As shown, combined with Figure 3 It is understood that in one embodiment, the cutting device 100 is provided with an additional driving rod 57B and an additional connecting block 58B to drive the second mounting seat 56 to slide. Among them, the additional connecting block 58B is fixedly connected to the second mounting seat 56, and the additional driving rod 57B and the additional connecting block 58B are threadedly connected to drive the second mounting seat 56 to move relative to the base 6 in the third direction y through the rotation of the additional driving rod 57B. The structure of the additional driving rod 57B and the additional connecting block 58B is similar to that of the driving rod 57A and the connecting block 58B, and will not be repeated here. Similarly, the second mounting seat 56 may also be provided with an additional sliding block 59B, and the structure of the additional sliding block 59B is the same as that of the sliding block 59A, so it will not be repeated here. Four additional sliding blocks 59B are arranged in groups of two, and each group is respectively sleeved on the third sliding rod 53 and the fourth sliding rod 54, so that the second mounting seat 56 can slide in the extension direction of the third sliding rod 53 and the fourth sliding rod 54.

[0141] See also Fig.13 , Fig.13 This is a schematic diagram of the matching structure of the first sliding rod, the second sliding rod, the third sliding rod and the fourth sliding rod in the cutting device of the embodiment of the present application.

[0142] like Fig.13 As shown, combined with Figure 3It is understood that in order to further make the structure of the cutting device compact, when the cutting device includes the first sliding rod 51, the second sliding rod 52, the third sliding rod 53 and the fourth sliding rod 54 at the same time, the first sliding rod 51 and the third sliding rod 53 are arranged to coincide with and connect with each other, and the second sliding rod 52 and the fourth sliding rod 54 are arranged to coincide with and connect with each other, so that the cutting device occupies a smaller area.

[0143] Furthermore, the first sliding rod 51 and the third sliding rod 53 can be set as an integral structure. The second sliding rod 52 and the fourth sliding rod 54 are an integral structure, thereby reducing the number of parts, simplifying the structure of the cutting device, and reducing the manufacturing cost of the cutting device.

[0144] It should be noted that, in another alternative embodiment, the first sliding rod 51 and the third sliding rod 53 may also be configured as a split structure connected to each other. The second sliding rod 52 and the fourth sliding rod 54 may also be configured as a split structure connected to each other. This application does not limit this.

[0145] The above is a description of the specific structure of the stage and related components. The following is a description of the components that may be included in the base.

[0146] See also Fig.14a , Fig.14a This is a schematic diagram of the structure of the base in the cutting device according to an embodiment of the present application. Fig.14b This is a schematic diagram of the control principle of the cutting device according to an embodiment of the present application.

[0147] like Figure 14a-14b As shown, combined with Figure 3 It is understood that the base 6 itself forms a receiving space 6A, and the receiving space 6A can be provided with any functional module.

[0148] Exemplarily, in one embodiment, a vacuum pump (not shown) is provided in the accommodating space 6A, one end of which is connected to the stage 1, and the interior of the stage 1 is evacuated to a vacuum, so that the screen 7 placed on the mounting surface 10 of the stage 1 can be adsorbed and fixed to the mounting surface 10 of the stage 1, and the fixing effect is better.

[0149] Furthermore, the mounting surface 10 of the stage 1 may be covered with a layer of silicone pad having through holes, so as to cooperate with the vacuum pump to further enhance the fixing ability of the stage 1 to the screen 7 and prevent it from shifting during cutting.

[0150] Exemplarily, a heating component 84 may be provided in the accommodation space 6A, and the heating component 84 is configured to be connected to the stage 1 and to heat the mounting surface of the stage 1. Thus, the adhesive layer 73 of the screen 70 may be softened by heating during cutting (see Figure 1a to Figure 2 ), which makes the cutting resistance smaller, the cutting smoother, and the success rate of separating the inner and outer screens higher.

[0151] like Fig.14b As shown, in one example, various types of sensors can also be provided in the accommodation space 6A. For example, the cutting device 100 is provided with a pressure sensor 83, a speed sensor 81 and a temperature sensor 86, and a speed controller 80, a forward and reverse controller 82 and a heating component 84 are provided accordingly. When the cutting device 100 is working, the pressure sensor 83 and the speed sensor 81 can monitor the force of the cutting line 4 in real time during the cutting process, and give an alarm in time when the cutting line 4 is subject to large resistance, and adjust the speed and rotation direction of the driving component 22 in time through the speed controller 80 and the forward and reverse controller 82, so as to avoid the cutting line 4 from collapsing due to the high cutting speed and large resistance, thereby damaging the intact inner screen. By providing a temperature sensor 86, data can be transmitted to the temperature controller 85, and the heating component 84 can keep the temperature of the stage 1 at a constant value (for example, 85°C), so that the adhesive layer is easier to cut.

[0152] The above is a detailed description of the structure and function of each component of the cutting device 100 in the present application. In order to make the working principle of each component clearer, the following will combine the drawings to illustrate the separation process by taking the inner screen and outer screen of a separated screen (for example, a curved screen) as an example.

[0153] See also Figure 15a-Figure 19 , Figure 15a-Figure 19 Schematic diagram of the principle of the cutting device in the embodiment of the present application to separate the inner and outer screens of the screen.

[0154] like Figure 15a-Figure 19 As shown, the specific steps of the cutting device separating the inner screen and the outer screen of the screen are as follows.

[0155] First, if Figures 15a to 15c , the screen 7 is placed on the stage 1 (wherein the surface of the outer screen 72 of the screen 7 facing away from the inner screen 71 is arranged toward the stage 1, and the surface of the inner screen 71 facing away from the outer screen 72 is arranged away from the stage 1), thereby fixing the screen 7, and heating the screen 7 by ... Fig.14b ) is heated to soften the adhesive layer 73 of the screen 7 to reduce the resistance when the adhesive layer 73 is cut. The winding rod 21 starts to rotate, thereby driving the cutting section 41 to start reciprocating along its own extension direction.

[0156] Then, the first guide portion 3A and the second guide portion 3B are adjusted to have a height difference in the second direction z, so that the cutting section 41 is inclined relative to the screen 7 (or it can be understood that the cutting section 41 has an angle with the first direction x, see Figure 15b to Figure 15c After each guide portion 30 is adjusted to a position, the screen 7 is rotated to one of the corners of the screen 7 so that the surface of the outer screen 72 facing the inner screen 71 is tangent to the cutting section 41 (see Fig.15c ), and gradually adjust the height of the cutting section 41 by adjusting each guide part 30 (or it can be understood that the cutting section 41 is pressed down as a whole), so that the cutting section 41 begins to cut into the screen 7.

[0157] like Figure 16a to Figure 16b As shown, after cutting in, by adjusting the angle of the cutting section 41 and rotating the stage 1 at the same time, the cutting section 41 gradually cuts into an arcuate edge 7A in the width direction of the screen 7 (or can be understood as the long side of the screen 7), and gradually cuts downward along the edge of the arcuate edge 7A. When cutting to the bottom surface of the arcuate edge 7A, the cutting section 41 can be adjusted to be parallel to the first direction x, and the adhesive layer 73 (see FIG. 1 ) of the arcuate edge 7A is bonded to the adhesive layer 73 of the arcuate edge 7A. Fig.15c ) is cut.

[0158] like Figure 17-Figure 18 As shown, combined with Figure 1a to Figure 1c It is understood that after the adhesive layer 73 of the arc edge 7A is cut, the stage 1 is moved in the third direction y to cut the straight plate area 7B of the screen 7. During cutting, the pressure sensor 83 and other components (see Fig.14b ) monitors and adjusts the force of the cutting wire 4 in real time, and when the cutting section 41 is loosened due to resistance, the winding rod 21 is moved in the third direction y to re-tighten the loose cutting section 41 and continue cutting. After repeatedly (usually three times) cutting the adhesive layer 73 of the straight plate area 7B, it can be ensured that the adhesive layer 73 will not be re-bonded due to gravity, and the cutting of the adhesive layer 73 of the straight plate area 7B is completed.

[0159] like Fig.19 As shown, combined with Figure 1a to Figure 1c It is understood that, finally, the adhesive layer 73 of the other curved edge 7A of the screen 7 needs to be separated. Compared with the initial cutting, at this time, the cutting segment 41 only needs to cut along the curved edge 7A to ensure that the cutting segment 41 only contacts the outer screen 72 without the risk of cutting the inner screen 71. And because the outer screen 72 itself is in a damaged state, it does not need to be recycled. Therefore, it is only necessary to continue to move the stage 1 in the third direction y, so that the cutting segment 41 can cut the adhesive layer 73 along the shape of the other curved edge 7A, and complete the cutting of the adhesive layer 73 of the other curved edge 7A, so that the intact inner screen 71 and the damaged outer screen 72 can be completely separated, and the inner screen 71 can be used for recycling.

[0160] Based on the possible structures of the above cutting equipment and the example separation process, it can be obviously seen that compared with the cutting equipment in the prior art, when the cutting equipment provided in the present application separates the inner screen 71 and the outer screen 72 of the screen 7, the cutting path of the cutting segment 41 can be consistent with the shape of the screen 7 itself throughout the entire process, so it is not easy to cut the inner screen 71, thereby improving the separation success rate and reducing the maintenance cost of the curved screen electronic device.

[0161] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
