[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] See also Figure 1-Figure 3 , this application provides the following technical solutions:

[0047] A splitting mechanism includes a first splitting part 1 and a second splitting part 2 which are arranged opposite to each other. The two are arranged on one side of a mobile phone screen to be split, respectively. A splitting line 3 is arranged between the first splitting part 1 and the second splitting part 2. The splitting line 3 is a wire, and its two ends are respectively fixed on the first splitting part 1 and the second splitting part 2. The mobile phone screen is split through the part of the splitting line 3 between the first splitting part 1 and the second splitting part 2. A tensioning part 4 is also arranged on the path through which the splitting line 3 passes, and the splitting line 3 is tensioned by the tensioning part 4 to ensure that the splitting line 3 can achieve a good splitting effect. The specific material of the splitting line 3 can be selected according to actual conditions. In this solution, a steel wire is used.

[0048] When this mechanism is in use, the first dividing part 1 and the second dividing part 2 need to be arranged on both sides of the mobile phone screen conveying path, and the dividing line 3 is tightened by the first dividing part 1, the second dividing part 2 and the tensioning part 4. As the mobile phone passes between the first dividing part 1 and the second dividing part 2, the dividing line 3 is inserted between the components of the mobile phone screen and separates the components, that is, the CG cover plate and the bonded display screen are separated.

[0049] Based on the above implementation scheme, see Figure 2The first segmentation part 1 includes a first segmentation roller 11, a first segmentation motor 12 and a first guide wheel set 13. One end of the segmentation line 3 is fixedly connected to the first segmentation roller 11. The first segmentation motor 12 is linked with the first segmentation roller 11 to drive the first segmentation roller 11 to rotate. The first guide wheel set 13 is arranged on the side of the first segmentation roller 11 facing the second segmentation part 2, and is used to guide the portion of the segmentation line 3 close to the first segmentation roller 11.

[0050] See also Figure 3 Similar to the first segmentation part 1, the second segmentation part 2 includes a second segmentation roller 21, a second segmentation motor 22 and a second guide wheel group 23. The second segmentation roller 21 is fixedly connected to the other end of the segmentation line 3; the second segmentation motor 22 is linked with the second segmentation roller 21, and the second segmentation roller 21 is driven to rotate by the second segmentation motor 22; the second guide wheel group 23 is arranged on the side of the second segmentation roller 21 facing the first segmentation part 1, and is used to guide the portion of the segmentation line 3 close to the second segmentation roller 21. The tensioning part 4 is arranged at the position of the second guide wheel group 23.

[0051] When the device is working, the first dividing part 1 and the second dividing part 2 respectively drive the first dividing roller 11 and the second dividing roller 21 thereof to rotate in the same direction, so that the dividing line 3 forms a movement from the first dividing part 1 toward the second dividing part 2, or from the second dividing part 2 toward the first dividing part 1, and the movement direction is perpendicular to the movement direction of the mobile phone screen. Through this structure, when the mobile phone screen passes through, in addition to the relative displacement caused by the tightening of the dividing line 3 and the mobile phone screen, the movement of the dividing line 3 itself can make the division easier.

[0052] On the basis of the above implementation scheme, the specific setting scheme for the guide structure of the dividing line 3 is as follows:

[0053] The first guide wheel group 13 includes a movable wheel 132 and two first fixed wheels 131. The first guide wheel group 13 and the first fixed wheel 131 are both arranged on the first guide plate 133. A vertical long groove is provided on the first guide plate 133. The wheel axle of the movable wheel 132 is slidably connected with the long groove, and its position in the long groove can be fixed by a locking nut, and an adjustment structure corresponding to the height adjustment of the movable wheel 132 in the vertical direction is formed by the long groove. The first fixed wheel 131 is rotatably arranged on both sides above the movable wheel 132; after the dividing line 3 extends from the first dividing roller 11, it first bypasses the upper side of the first fixed wheel 131 close to the first dividing roller 11, then turns to the lower side of the movable wheel 132, bypasses the movable wheel 132, and then bypasses toward the upper side of the other first fixed wheel 131, and extends toward the second dividing portion 2.

[0054] The second guide wheel group 23 includes a second guide plate 233, on which two second fixed wheels 231 are rotatably arranged. The two second fixed wheels 231 are at the same horizontal height as the first fixed wheel 131; the dividing line 3 is overlapped on the upper side of the second fixed wheel 231 and then fixed on the second dividing roller 21.

[0055] The tensioning part 4 includes a tensioning wheel 41, which is arranged above the two second fixed wheels 231 and between the two second fixed wheels 231; the dividing line 3 passes under the tensioning wheel 41. A tensioning member 42 is arranged in linkage with the tensioning wheel 41, and the tensioning member 42 is a cylinder or an electric push rod, and the tensioning wheel 41 is driven to rise or fall in the vertical direction through the tensioning member 42.

[0056] Through this structure, a guide structure of the dividing line 3 is formed. In fact, the tensioning of the dividing line 3 is not simply completed by the tensioning part 4 independently. In the first guide wheel group 13 of the first dividing part 1, the movable wheel 132 also plays a role in helping the tensioning of the dividing line 3, but the movable wheel 132 belongs to the tensioning of the fixed position under normal conditions, and its position may only be adjusted during equipment debugging. The tensioning member 42 drives the lifting and lowering movement of the tensioning wheel 41, which provides active adjustability for the tensioning force of 3.

[0057] On the basis of the above embodiment, the tensioning part 4 is further provided with a tensioning frame 43, the tensioning wheel 41 is rotatably arranged on the tensioning frame 43, and the tensioning frame 43 is connected to the movable end of the tensioning member 42. The tensioning frame 43 specifically includes a first tensioning frame and a second tensioning frame, and the first tensioning frame is fixedly connected to the movable end of the tensioning member 42; see Figure 3 The movable end of the tensioning member 42 is a liftable rod, and the first tensioning frame is a "7"-shaped plate. The lower side of the horizontal plate of the first tensioning frame is fixedly connected to the upper end of the tensioning member 42. The second tensioning frame also uses a "7"-shaped right-angle plate structure. Its horizontal plate is overlapped above the horizontal plate of the first tensioning frame, the second tensioning frame is connected to the first tensioning frame, and the axle of the tensioning wheel 41 is fixedly set on the second tensioning frame.

[0058] Because the tension wheel 41 may be severely worn during long-term use, the structure of the present invention facilitates the installation of the tension wheel 41 and its disassembly and replacement during later maintenance.

[0059] On the basis of the above implementation scheme, the difference from the above implementation scheme is that the second tensioning frame and the first tensioning frame can be raised and lowered synchronously, and the two are connected by horizontal sliding. There are many forms of implementing this functional structure, such as a "T"-shaped slider is set on the upper end of the first tensioning frame, and a "T"-shaped slide groove is correspondingly set on the second tensioning frame. Through the connection between the slider and the slide groove, when the first tensioning frame is raised and lowered, the second tensioning frame must follow the lifting and lowering, and the lifting process does not affect the horizontal movement of the second tensioning frame.

[0060] A tensioning adjusting member 44 is disposed on a horizontal side of the second tensioning frame. The tensioning adjusting member 44 may be an electric push rod, the movable end of which is connected to the second tensioning frame, and the second tensioning frame is driven to move in the horizontal direction through the tensioning adjusting member 44.

[0061] The length direction of the dividing line 3 is taken as the longitudinal direction. Considering that the dividing line 3 may be displaced in the lateral direction during the dividing process, a tensioning adjustment member 44 is provided. An annular groove corresponding to the dividing line 3 is provided on the wheel body of the tensioning wheel 41, so that the dividing line 3 can be inserted into the annular groove of the tensioning wheel 41. The lateral position of the above-mentioned dividing line 3 is adjusted and controlled by the tensioning adjustment member 44.

[0062] On the basis of the above embodiment, different from the previous embodiment, this embodiment adopts the structure of the guide clamping roller group 5 as the limiting structure in the transverse direction of the dividing line 3. There are two sets of guide clamping roller groups 5, which are respectively arranged near the first guide wheel group 13 and the second guide wheel group 23; each guide clamping roller group 5 includes two guide clamping rollers arranged in parallel, the axial direction of the guide clamping rollers is in the vertical direction, and the dividing line 3 passes between the two guide clamping rollers. The transverse position of the dividing line 3 is limited and fixed by the guide clamping rollers.

[0063] On the basis of the above implementation scheme, in order to adjust the height position of the first guide wheel group 13 and the second guide wheel group 23 , this solution provides a guide adjustment structure 6 for each of the first guide wheel group 13 and the second guide wheel group 23 .

[0064] The first segmentation part 1 and the second segmentation part 2 are respectively provided with a fixed bracket, on which the motor and the segmentation roller assembly of the first segmentation part 1 and the second segmentation part 2 are provided, and the first guide plate 133 and the second guide plate 233 are respectively provided on one side of the corresponding fixed bracket, and are slidably connected with the fixed bracket in the vertical direction. A threaded hole is respectively provided on the upper edge of the first guide plate 133 and the second guide plate 233, and an adjusting screw is rotatably provided on the fixed bracket, and the adjusting screw extends downward and is threadedly connected with the first guide plate 133 and the second guide plate 233. By rotating the adjusting screw, the height of the first guide plate 133 and the second guide plate 233 can be adjusted.

[0065] On the basis of the above implementation scheme, a photoelectric sensor is mounted on the first guide plate 133 or the second guide plate 233, such as Figure 2 As shown, the photoelectric sensor of the present solution is arranged on the first guide plate 133, and its sensing end is arranged toward the dividing line 3, so as to provide feedback on whether the dividing line 3 is broken.

[0066] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
