Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of device manufacturing, in particular to a display screen cutting jig. BACKGROUND

[0002] In the display screen manufacturing and post-processing process, especially in the cutting and separation operation of glass substrate, OLED panel or flexible display, the traditional mechanical cutting method often has many problems. For example, after using a knife wheel to scribe, mechanical external force is applied to break, although the process is mature, but for large size, ultra-thin or special coating structure display screen, it is easy to cause crack deviation, rough fracture surface, edge cracking and other defects, which seriously affects the product yield and appearance consistency. In addition, in order to ensure the cutting accuracy, manual operation is still indispensable, the overall processing efficiency is low, the automation degree is limited, and it is difficult to meet the modern mass production and flexible production demand.

[0003] In recent years, some enterprises have begun to try to introduce laser cutting equipment for non-contact pre-cutting, using laser beam to form heat stress induced micro-crack path on the surface of the display screen, in order to reduce the breaking resistance. However, due to the lack of cooperation with the subsequent breaking mechanism and clamping structure, manual transfer or separate force is still needed after laser cutting, the cutting consistency is poor, the fracture control force is insufficient, and multiple crack propagation or screen damage is easy to occur. In addition, the clamping mechanism in the existing equipment is mostly static positioning method, which cannot dynamically respond to the small deformation or vibration of the display screen in the processing process, which is not conducive to the stability of high-precision breaking operation.

[0004] Therefore, it is urgent to develop a composite processing jig device integrating laser pre-cutting, synchronous breaking and adaptive clamping, to solve the key problems of low cutting precision, poor fracture control, low processing efficiency and insufficient automation level in the prior art, so as to improve the overall process level and manufacturing efficiency of display screen cutting process.

DETAILED DESCRIPTION

[0046] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0047] The specific implementation of the present application is described in detail below in combination with specific embodiments.

[0048] In one embodiment, a display screen cutting jig, see Figures 1 to 11 , comprising a mounting support plate 1, the mounting support plate 1 is connected with a first mounting plate 3 through a first telescopic rod 2, a display screen 10 is arranged below the first mounting plate 3, the display screen 10 is arranged above a supporting leg 11, further comprising:

[0049] A breaking mechanism 4 is connected with the first mounting plate 3 through a fourth mounting frame 13, the breaking mechanism 4 comprises a first mounting frame 41, a folding power assembly 42 and a folding assembly 43, the first mounting frame 41 is fixedly connected with the breaking mechanism 4, the first mounting frame 41 is uniformly distributed about the first mounting plate 3, the first mounting frame 41 is arranged above the display screen 10, the folding power assembly 42 is arranged on the first mounting frame 41, the first mounting frame 41 is movably connected with the folding power assembly 42, the first mounting frame 41 is movably connected with the folding assembly 43, the folding assembly 43 is movably connected with the folding power assembly 42, and the folding assembly 43 is movably connected with the display screen 10;

[0050] A second mounting ring 8 is fixedly connected with the mounting support plate 1, a second telescopic rod 14 is arranged inside the second mounting ring 8, one end of the second telescopic rod 14 is fixedly connected with the inside of the second mounting ring 8, the second telescopic rod 14 is uniformly distributed about the second mounting ring 8, and the other end of the second telescopic rod 14 is provided with a clamping mechanism 9, the clamping mechanism 9 is connected with the display screen 10;

[0051] The folding power assembly 42 comprises a first power piece 421, a first transmission frame 422, a sliding block 423, a limiting rod 424, a second transmission frame 425 and a connecting pin 426, the first power piece 421 is movably connected with the first mounting frame 41, the first power piece 421 is movably connected with the first transmission frame 422, the first transmission frame 422 is movably connected with the second transmission frame 425, the second transmission frame 425 is movably connected with the first mounting frame 41, the second transmission frame 425 is provided with the connecting pin 426 inside, the connecting pin 426 is movably connected with the limiting rod 424, the limiting rod 424 is movably connected with the sliding block 423, and the sliding block 423 is fixedly connected with the folding assembly 43;

[0052] The folding assembly 43 includes a sliding rod 431 and a folding member 432. The sliding rod 431 passes through the first mounting frame 41 and is movably connected to the first mounting frame 41. The sliding rod 431 is fixedly connected to the sliding block 423. One end of the sliding rod 431 is fixedly connected to the folding member 432. The folding member 432 is connected to the display screen 10.

[0053] The first power member 421 initiates the drive, and the first power member 421 is fixed to the inner side of the first mounting frame 41. The driving force generated by the first power member 421 is transmitted through the first transmission frame 422 connected thereto. The transmission frame 422 forms a linkage cooperation relationship with the second transmission frame 425. When the first transmission frame 422 pushes the second transmission frame 425 to rotate or translate, it drives the connecting pin 426 provided therein to move. The connecting pin 426 further pushes the limit rod 424 to move along the set trajectory, thereby driving the sliding block 423 to generate linear displacement. The sliding block 423 is fixedly connected to the sliding rod 431 in the folding assembly 43 below. As the sliding block 423 moves, the sliding rod 431 slides vertically downward along the guide hole in the first mounting frame 41.

[0054] The sliding rod 431 in the folding assembly 43 is passed through the first mounting frame 41, with its upper end connected to the sliding block 423 and the lower end fixedly connected to the folding member 432. The folding member 432 serves as the final pressure structure, and slowly presses down to contact the surface of the display screen 10 during the sliding process. Multiple such folding members 432 are evenly arranged, and through the set limit rod 424 and connecting pin 426, the folding member 432 can be controlled, limited, and has an end buffer during the pressing process.

[0055] In this embodiment, during the initial placement phase, the display screen 10 is supported by support legs 11 and secured by clamping mechanisms 9. Clamping mechanisms 9 are connected to second mounting ring 8 via second telescopic rods 14. This mounting ring is secured to the mounting support plate 1 and features multiple second telescopic rods 14 evenly distributed along the ring. This provides multi-point locking and adaptive wrapping for displays of varying sizes, enhancing clamping stability and anti-disturbance capabilities, ensuring that the display screen 10 does not shift, warp, or vibrate during the entire processing process.

[0056] The breaking mechanism 4 is positioned below the first mounting plate 3 and above the display screen 10. It is fixedly connected to the first mounting plate 3 via a fourth mounting bracket 13. Multiple breaking mechanisms 4 are evenly distributed across the first mounting plate 3, forming a multi-point, synchronized breaking mechanism. Each set of breaking mechanisms 4 comprises an integrally constructed first mounting bracket 41, a folding power assembly 42, and a folding assembly 43. These three components sequentially form a power transmission path, ultimately applying a breaking force to a designated location on the display screen surface.

[0057] The folding power assembly 42 is driven as follows: First, the first power member 421 initiates the drive. The first power member 421 is fixed to the inside of the first mounting frame 41. The driving force generated by the first power member 421 is transmitted through the first transmission frame 422 connected thereto. This transmission frame 422 forms a linkage with the second transmission frame 425. When the first transmission frame 422 pushes the second transmission frame 425 to rotate or translate, it drives the connecting pin 426 disposed within it. This connecting pin 426 further pushes the limit rod 424 along a set trajectory, thereby driving the sliding block 423 to produce linear displacement. The sliding block 423 is fixedly connected to the sliding rod 431 in the folding assembly 43 below. As the sliding block 423 moves, the sliding rod 431 slides vertically downward along the guide hole in the first mounting frame 41.

[0058] The sliding rod 431 in the folding assembly 43 is passed through the first mounting frame 41, with its upper end connected to the sliding block 423 and the lower end fixedly connected to the folding piece 432. As the final pressure structure, the folding piece 432 slowly presses down to contact the surface of the display screen 10 during the sliding process, and is usually located directly above the pre-cut area. A plurality of such folding pieces 432 are evenly arranged, and can simultaneously apply pressure on multiple pre-cut areas, thereby achieving directional brittle fracture of the glass or display screen without relying on high-intensity external force impact, greatly reducing the risk of edge chipping, edge collapse or oblique fracture. Since the limiting rod 424 and the connecting pin 426 are provided in the power transmission structure, the folding piece 432 is controllable and limited during the downward pressing process, and has a termination buffer function, which further improves the safety and stability of the processing process.

[0059] The driving force of the breaking mechanism 4 is applied steadily, slowly, and evenly to the preset breaking position of the display screen 10, supplemented by the peripheral fixing structure of the clamping mechanism 9, forming an operating system with vertical coordination and left-right stabilization. The distributed layout of multiple sets of powered folding mechanisms and their linkage through transmission components achieve high-precision, multi-point synchronous fracture processing of the display screen at low stress levels. This is particularly suitable for industrial fracture processing scenarios of brittle materials such as thin glass, flexible panels, and OLED screens.

[0060] In one embodiment, see Figures 1 to 11 , the clamping mechanism 9 includes:

[0061] A clamping and mounting assembly 91 , one end of which is fixedly connected to the second telescopic rod 14 , and the clamping and mounting assembly 91 is evenly distributed about the display screen 10 ;

[0062] A clamping power assembly 92, wherein the clamping power assembly 92 is disposed on the clamping mounting assembly 91 and is movably connected to the clamping mounting assembly 91;

[0063] A clamping plate 93 is movably connected to the clamping power assembly 92.

[0064] Further, referring to Figures 1 to 11 The clamping mounting assembly 91 comprises:

[0065] A third mounting bracket 911 is fixedly connected to the second telescopic rod 14, and the third mounting bracket 911 is uniformly distributed about the display screen 10.

[0066] A second sliding groove 912 is arranged on the third mounting bracket 911, and the second sliding groove 912 is movably connected to the clamping power assembly 92. The second sliding groove 912 comprises a horizontal groove and a vertical groove.

[0067] Further, referring to Figures 1 to 11 The clamping power assembly 92 comprises:

[0068] A sliding block 921 is movably connected to the horizontal groove in the second sliding groove 912, and the sliding block 921 is movably connected to one end of a transmission rod 922. The sliding block 921 is connected to the clamping plate 93.

[0069] A second power member 923 is movably connected to the vertical groove in the second sliding groove 912, and the second power member 923 is movably connected to the other end of the transmission rod 922.

[0070] In this embodiment, the clamping mechanism 9 is used to stably clamp the edges of the display screen 10 at multiple points before cutting or breaking the display screen 10, so as to prevent displacement, vibration or warping during processing, and to ensure accurate transmission of the breaking line force. The clamping mechanism is integrally installed on the inner side of the second mounting ring 8, and is connected to the external structure through the second telescopic rod 14. The second telescopic rod 14 can be telescoped and adjusted according to the position of the display screen of different sizes, so as to realize adaptive clamping.

[0071] The clamping mechanism 9 mainly comprises a clamping mounting assembly 91, a clamping power assembly 92 and a clamping plate 93. The third mounting bracket 911 in the clamping mounting assembly 91 serves as a support frame of the overall structure. One end of the third mounting bracket 911 is fixedly connected to the second telescopic rod 14, and is uniformly distributed around the display screen 10 through the multiple groups of structures arranged thereon. The third mounting bracket 911 is provided with a second sliding groove 912, which comprises a horizontal groove and a vertical groove, and constitutes a two-dimensional sliding constraint path, which is the guide basis of the clamping power assembly 92.

[0072] The clamping power assembly 92 comprises a sliding block 921, a transmission rod 922 and a second power piece 923. The sliding block 921 is movably connected to the horizontal slot of the second sliding groove 912 and has the ability to slide in the horizontal direction. One end of the sliding block 921 is connected to the transmission rod 922, and the transmission rod 922 converts the horizontal displacement into the linkage action in the clamping direction. The other end of the transmission rod 922 is connected to the second power piece 923, and the second power piece 923 is installed in the vertical slot of the second sliding groove 912 and can extend in the vertical direction. When the second power piece 923 is started, the output linear displacement of the second power piece 923 makes the transmission rod 922 swing, and then drives the sliding block 921 to move in the horizontal slot to the clamping direction.

[0073] The sliding block 921 is directly connected to the clamping plate 93, so the horizontal movement of the sliding block 921 drives the clamping plate 93 to move close to the edge of the display screen 10. When all the clamping mechanisms act simultaneously, the plurality of clamping plates 93 will move synchronously from the respective installation positions to the edge of the display screen, and the pressure is applied at multiple points at the same time, so that the edge of the display screen is uniformly clamped. The clamping force comes from the driving output of the second power piece 923, which can be adjusted by the stroke and pressure parameters to adapt to the edges of the screen bodies of different thicknesses or materials. In addition, the clamping plate 93 is movably connected, and its structure can have a flexible cover or a non-slip surface to improve the clamping stability and prevent the screen body surface from being scratched.

[0074] In one embodiment, referring to Figures 1 to 11 , the mounting support plate 1 is fixedly connected to the mounting frame 12, the second mounting frame 5 is arranged in the mounting frame 12, the second mounting frame 5 is uniformly distributed about the mounting frame 12, the first sliding groove 6 is arranged in the second mounting frame 5, and the first installation ring 7 is movably connected to the first sliding groove 6.

[0075] Further, referring to Figures 1 to 11 , the first installation ring 7 is movably connected to the first sliding groove 6, and the laser cutting mechanism 15 is arranged above the display screen 10.

[0076] Further, referring to Figures 1 to 11 , the laser cutting mechanism 15 comprises:

[0077] The third sliding groove 1501 is arranged in the first installation ring 7, the third sliding groove 1501 is movably connected to the third power piece 1502, and the third power piece 1502 is symmetrically arranged about the first installation ring 7;

[0078] The third telescopic rod 1503 is arranged on the third power piece 1502, and the laser cutting head 1504 is installed on the third telescopic rod 1503.

[0079] In the embodiment, the laser cutting mechanism 15 is used for precise pre-cutting operation on the surface of the display screen 10 before processing, so as to form controllable micro-cracks or heat weakening paths on the display screen material, and provide guidance and crack starting point for subsequent mechanical breaking operation. The laser cutting mechanism 15 is mounted inside the first mounting ring 7, and the first mounting ring 7 is movably connected in the second mounting frame 5 through the first sliding groove 6, and the second mounting frame 5 is uniformly distributed inside the mounting frame 12, and the mounting frame 12 is fixedly arranged on the mounting support plate 1. Through such hierarchical arrangement, the laser cutting mechanism 15 can be positioned and moved above the entire processing area, covering the entire surface of the display screen 10.

[0080] The third sliding groove 1501 is fixedly arranged on the inner side of the first mounting ring 7, and is used for limiting the movement track of the laser cutting assembly and providing lateral guide support. The third sliding groove 1501 can be a linear guide rail or a groove type sliding groove, and the extension direction is parallel to the long side of the display screen 10 or the cutting path direction, so as to realize the sliding of the cutting head in the horizontal direction. The third sliding groove 1501 movably connects the third power member 1502, and the third power member 1502 can adopt the form of an electric sliding block, an electric screw or a guide rail sliding table, and can drive the laser assembly to move accurately along the sliding groove 1501. The third power member 1502 is symmetrically arranged about the first mounting ring 7, so as to ensure the structural stability and force balance of the cutting head in the running process, and is suitable for high-speed or repeated running scenes.

[0081] The third power member 1502 is provided with a third telescopic rod 1503, and the third telescopic rod 1503 is a height adjusting assembly, one end of which is fixed to the third power member 1502, and the other end of which is suspended and connected to the laser cutting head 1504. The third telescopic rod 1503 can be selected from the form of a micro electric cylinder, a linear actuator or a piezoelectric actuator, and can control the position height of the laser head in real time according to the laser processing parameters, so as to realize automatic focusing and laser power density adjustment, and adapt to display screens 10 with different thicknesses or materials.

[0082] The laser cutting head 1504 is installed at the end of the third telescopic rod 1503, and is an energy output unit of the mechanism, which can emit a high-power laser beam, and is used for directional heating, local melting, vaporization or micro-crack induction operation on the surface of the display screen 10. Through the transverse movement of the third power member 1502 along the third sliding groove 1501, the cutting operation on the transverse path of the display screen is realized, and the telescopic adjustment of the third telescopic rod 1503 ensures that the focusing position of the laser beam is constant and the power density is balanced during the processing.

[0083] The process flow is as follows: First, under the control of the first mounting ring 7, the laser cutting mechanism 15 aligns with the area to be cut on the display screen 10. The initial lateral position of the laser head 1504 is adjusted via the third sliding slot 1501. After the third power element 1502 is activated, it drives the laser cutting head 1504 along the sliding slot 1501, forming a continuous or intermittent cutting path. Simultaneously, the third telescopic rod 1503 adjusts the laser head height in real time based on microscopic height variations on the display screen surface or process parameters to ensure precise laser focus. The laser beam output by the laser cutting head 1504 ablates minute grooves or heated areas on the surface of the display screen 10, forming thermal stress concentration zones or ablation grooves. This reduces the critical stress required for the display screen material to fracture, and in conjunction with the subsequent breaking mechanism, creates a clear, stable, and controllable fracture line.

[0084] The working principle of the present invention is:

[0085] The laser cutting mechanism 15 first aligns with the area to be cut on the display screen 10 under the control of the first mounting ring 7, and adjusts the initial horizontal position of the laser head 1504 via the third sliding slot 1501. After the third power member 1502 is activated, it drives the laser cutting head 1504 to move along the sliding slot 1501, forming a continuous or intermittent cutting track. At the same time, the third telescopic rod 1503 adjusts the height of the laser head in real time according to the microscopic height changes on the display screen surface or process parameters to ensure accurate laser focusing. The laser beam output by the laser cutting head 1504 ablates fine grooves or heated areas on the surface of the display screen 10, forming a thermal stress concentration zone or ablation groove, thereby reducing the critical stress required for the display screen material to break, and cooperating with the subsequent breaking mechanism 4 to achieve a clear, stable, and controllable fracture line.

[0086] Located below the first mounting plate 3 and above the display screen 10, it is fixedly connected to the first mounting plate 3 via a fourth mounting bracket 13. Multiple breaking mechanisms 4 are evenly distributed across the first mounting plate 3, forming a multi-point, synchronized breaking mechanism. Each set of breaking mechanisms 4 comprises an integrally constructed first mounting bracket 41, a folding power assembly 42, and a folding assembly 43.
