[0045] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0046] This invention provides a cutting device for display panels, relating to the field of liquid crystal display panel cutting technology. It addresses the technical problems of long processing time and low product yield in the cutting and splitting of large master liquid crystal display panels. This invention utilizes the rotation of a rotary table to break the liquid crystal display panel, avoiding the repeated flipping of the panel in traditional cutting processes, thus improving cutting efficiency and quality. Specific embodiments are described in detail below.

[0047] Please see Figure 1 In one embodiment of this utility model, the liquid crystal display panel 10 of the large motherboard is rectangular, and multiple dividing lines 13 to be cut are pre-set on it. In this embodiment, along the feeding direction (e.g., Figure 1 (As shown by the horizontal arrow in the middle), mark the left part of the first dividing line as the cutting area 12 of the liquid crystal display panel 10, and mark the remaining part as the loading area 11 of the liquid crystal display panel 10.

[0048] Please see Figure 2In one embodiment of this utility model, the display panel cutting device may include a frame 20, a support platform 30, a rotary table 40, a drive module 50, and a cutting module 60. The frame 20 serves as the basic framework of the cutting device, providing mounting points for other units and modules. The support platform 30 is fixedly connected to the frame 20. The platform surface of the support platform 30 may be horizontal. The rotary table 40 is rotatably connected to the frame 20, and its rotation axis 42 is located on the side away from the support platform 30. The drive module 50 is connected to the frame 20, and its output end is connected to the rotary table 40. The drive module 50 drives the rotary table 40 to rotate around the rotation axis 42. The cutting module 60 is connected to the frame 20 and is used to cut the liquid crystal display panel 10 to form a cutting groove 14 on its surface.

[0049] Please see Figure 2 In one embodiment of this utility model, during the cutting and splitting process, the liquid crystal display panel 10 is first conveyed to a preset position, i.e., the loading area 11 can be located on the support platform 30, and the cutting area 12 can be located on the rotary table 40. The dividing line 13 between the loading area 11 and the cutting area 12 is located at the gap between the support platform 30 and the rotary table 40. At this time, the output end of the cutting module 60 can be aligned with the dividing line 13. Then, the cutting module 60 begins the cutting operation, cutting the liquid crystal display panel 10 to form a cutting groove 14 at the preset dividing line 13. Next, the drive module 50 drives the rotary table 40 to rotate around the rotation axis 42. It can be understood that the rotary table 40 will drive the cutting area 12 to rotate synchronously. Because the support platform 30 and the loading area 11 on it remain stationary, the loading area 11 and the cutting area 12 will have an angular difference, thereby generating a bending force at the cutting groove 14. At the same time, since the rotation axis 42 of the rotary table 40 is located on the side away from the support platform 30. Therefore, the rotary table 40 will also lift the side of the area to be cut 12 that is close to the area to be loaded 11. As a result, the area to be loaded 11 and the area to be cut 12 will generate shearing force at the cutting groove 14. Through the combined action of bending force and shearing force, the area to be loaded 11 and the area to be cut 12 will break at the cutting groove 14, thereby completing the bending and breaking operation.

[0050] Please see Figure 3 In one embodiment of this utility model, a plurality of first adsorption holes 31 are spaced apart on the surface of the support platform 30. The first adsorption holes 31 can be connected to a vacuum pump via a vacuum pipeline. By providing negative pressure through the vacuum pump, the plurality of first adsorption holes 31 can adsorb and fix the material-to-be-loaded area 11 of the liquid crystal display panel 10. Thus, it can be seen that during the aforementioned bending and breaking process, the adsorption and fixing effect of the first adsorption holes 31 can prevent the material-to-be-loaded area 11 from tilting upward.

[0051] Please see Figure 3In one embodiment of this utility model, a plurality of second adsorption holes 41 are spaced apart on the surface of the rotating table 40. The second adsorption holes 41 can be connected to a vacuum pump via a vacuum pipeline. By providing negative pressure through the vacuum pump, the plurality of second adsorption holes 41 can adsorb and fix the area 12 to be cut of the liquid crystal display panel 10. Thus, it can be seen that during the bending and breaking process described above, the adsorption and fixing effect of the plurality of second adsorption holes 41 can prevent the area 12 to be cut from tilting upward.

[0052] In one embodiment of this utility model, a conveyor belt and drive wheel structure may be provided on the platform of the support table 30. When all the first adsorption holes 31 and the second adsorption holes 41 are in a vacuum state, the conveyor belt can drive the liquid crystal display panel 10 to move from the support table 30 to the rotary table 40.

[0053] Please see Figure 3 In one embodiment of this utility model, a gap exists between the support platform 30 and the rotating platform 40. This gap ensures that the end of the rotating platform 40 does not interfere with the end of the support platform 30 during rotation. Simultaneously, this gap also allows the powder generated during the cutting of the liquid crystal display panel 10 to settle, preventing the cutting powder from affecting the quality of the liquid crystal display panel 10.

[0054] Please see Figure 2 In one embodiment of this utility model, the drive module 50 can be a hydraulic actuator. In this case, the output end of the drive module 50 can be connected to the end of the rotary table 40 near the support platform 30. The drive module 50 can control the lifting and lowering of its output end to drive the rotary table 40 to rotate around the rotation axis 42. It is understood that since the rotation axis 42 of the rotary table 40 is located at the end away from the support platform 30, when the drive module 50 drives the rotary table 40 and the area to be cut 12 on it to rotate, the support platform 30 and the area to be loaded 11 on it remain stationary. An angle difference will occur between the table surface of the rotary table 40 and the table surface of the support platform 30. The area to be cut 12 adsorbed on the rotary table 40 and the area to be loaded 11 adsorbed on the support platform 30 will also synchronously generate an angle difference, thereby forming a bending force. Simultaneously, the table surface of the rotary table 40 at the end near the support platform 30 will be raised relative to the table surface of the support platform 30. A height difference will occur at the connection point between the area to be cut 12 and the area to be loaded 11, i.e., at the cutting groove 14, thereby forming a shearing force.

[0055] Please see Figure 4 In one embodiment of this utility model, the drive module 50 can also be a drive motor. In this case, the output end of the drive module 50 can be connected to the rotation shaft 42 of the rotary table 40. The output shaft of the drive module 50 drives the rotation shaft 42, i.e., the rotary table 40, to rotate synchronously through gear transmission or belt transmission.

[0056] Please see Figure 2, Figure 3 In one embodiment of this utility model, the display panel cutting device further includes multiple limiting modules 80. The multiple limiting modules 80 can be arranged in groups on opposite sides of the rotary table 40. During cutting, the limiting modules 80 can press against the area 12 to be cut on the liquid crystal display panel 10 to prevent the area 12 to be cut from tilting relative to the table surface of the rotary table 40.

[0057] In this embodiment, the limiting module 80 may include a clamping part 81 and an adjusting bolt 82. One end of the adjusting bolt 82 is connected to the limiting base 41 on the side of the rotary table 40, and the other end is connected to the clamping part 81. By rotating the adjusting bolt 82, the distance between the clamping part 81 and the table surface of the rotary table 40 can be adjusted, thereby enabling the clamping part 81 and the table surface of the rotary table 40 to jointly clamp the liquid crystal display panel 10, preventing the liquid crystal display panel 10 from tilting upwards.

[0058] Please see Figure 2 In one embodiment of this utility model, the cutting device further includes a conveying module 70, which is connected to the frame 20 and can be located above the liquid crystal display panel 10. Its output end is in contact with the material loading area 11 of the liquid crystal display panel 10. In this embodiment, the conveying module 70 can be used to push the liquid crystal display panel 10 to move along the direction from the material loading area 11 to the cutting area 12.

[0059] Please see Figure 4 In one embodiment of this utility model, the conveying module 70 may include a drive motor 71, a rotating arm 72, and a roller 73. The drive motor 71 is connected to the frame 20. One end of the rotating arm 72 is rotatably connected to the frame 20. The roller 73 is rotatably connected to the other end of the rotating arm 72, and the roller 73 is drively connected to the output end of the drive motor 71. The rotation axis of the roller 73 is parallel to the dividing line 13 on the liquid crystal display panel 10. In this embodiment, the rotating arm 72 rotates towards the liquid crystal display panel 10 to drive the roller 73 to contact the upper surface of the liquid crystal display panel 10. Then, the drive motor 71 starts, driving the roller 73 to rotate. It is understood that when the liquid crystal display panel 10 is not constrained (e.g., the first adsorption hole 31 and the second adsorption hole 41 are in a vacuum state), the roller 73 can push it to move. In this embodiment, the outer peripheral surface of the roller 73 is provided with a flexible anti-slip material, such as rubber, to increase the friction between the roller 73 and the liquid crystal display panel 10.

[0060] Please see Figure 1 , Figure 5In one embodiment of this utility model, when laser beam cutting is used, the cutting module 60 may include a linear slide rail 61 and a laser 62. The linear slide rail 61 may be connected to the frame 61 and may be parallel to the dividing line 13 between the material loading area 11 and the cutting area 12. The laser 62 may be slidably connected to the linear slide rail 61, and its focal point may be located on the dividing line 13. In this embodiment, in order to form a complete cutting groove 14 along the cutting line 13, firstly, the focal point of the laser 62 is aligned with one end of the dividing line 13, and the emitted laser beam breaks the molecular bonds of the material, physically removing a portion of the material on the upper surface of the liquid crystal display panel 10; simultaneously, the laser 62 moves along the linear slide rail 61 at a preset speed, and its focal point moves synchronously along the dividing line 13, thereby forming a cutting groove 14 at the corresponding position. The laser beam physically removes a portion of the liquid crystal display panel 10 by breaking the molecular bonds within the glass.

[0061] Please see Figure 1 , Figure 6 In one embodiment of this utility model, when a cutting wheel is used for cutting, the cutting module 60 may include a swing arm 63 and a cutting wheel 64. One end of the swing arm 63 is rotatably connected to the frame 20. The cutting wheel 64 is rotatably connected to the other end of the swing arm 63. In this embodiment, the cutting wheel 64 has cutting teeth on its circumference. The swing arm 63 has a rotating joint; by swinging the swing arm 63 and rotating its rotating joint, the cutting wheel 64 can move along the dividing line 13. A drive motor is provided connecting the cutting wheel 64 and the swing arm 63, which drives the cutting wheel 64 to rotate, thereby cutting the upper surface of the liquid crystal display panel 10 to form a cutting groove 14.

[0062] In summary, the display panel cutting device disclosed in this utility model solves the technical problems of long processing time and low product yield in the cutting and splitting of large mother display panels. This utility model utilizes the rotation of a rotary table to break the liquid crystal display panel, avoiding the repeated flipping of the liquid crystal display panel in the traditional cutting process, thus improving the cutting efficiency and quality. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
