[0003] Currently, common laser repair equipment mainly consists of a support platform and a laser located on top of it.

[0006] Based on the aforementioned laser repair platform for display panels, when display panel repair is required, the display panel is first placed onto the conveying surface of the first conveying component manually or by a robotic arm. Because the starting end of this conveying surface is relatively low, this design significantly reduces the labor intensity and handling time for operators. Subsequently, the first conveying component transports the display panel to the second conveying component. As the panel transfers between the two, it naturally falls due to the height difference between the conveying surfaces; at this time, the elastic support structure provides stable support for the falling display panel, allowing it to transition gently and smoothly onto the conveying surface of the second conveying component. Finally, the second conveying component accurately transports the display panel to the machine's limiting base, completing the loading and positioning at the laser repair station.

[0011] In one embodiment of the laser repair platform for the display panel described above, the elastic element includes a connecting part, a deformable part, and a supporting part arranged sequentially in the vertical direction; the connecting part is connected to the mounting plate, and the deformable part, when pressed, can drive the supporting end to move in the vertical direction, so as to drive the supporting part into and out of the mounting space; wherein, the top surface of the supporting part is a smooth curved surface.

[0012] In one embodiment of the laser repair platform for display panels described above, the machine tool is provided with a guide rail module on the side facing the first conveying component, and the mounting plate is slidably connected to the machine tool through the guide rail module to adjust the position of the elastic bearing structure in the conveying direction of the display panel.

[0013] In one embodiment of the laser repair platform for the display panel described above, the limiting base is provided with a guide structure on the side near the second conveying component. The guide structure includes two oppositely arranged guide bars, and a guide space for guiding the movement of the display panel is formed between the two guide bars.

[0014] The above-described one or more embodiments of this application have at least one or more of the following beneficial effects: When display panel repair is required, the panel is first placed onto the conveyor surface of the first conveyor assembly manually or by a robotic arm. Because the starting point of this conveyor surface is low, this design significantly reduces the labor intensity and handling time for operators. Subsequently, the first conveyor assembly transports the display panel to the second conveyor assembly. As the panel moves between the two, it naturally falls due to the height difference between the conveyor surfaces; at this time, the elastic support structure provides stable support for the falling display panel, allowing it to transition gently and smoothly onto the conveyor surface of the second conveyor assembly. Finally, the second conveyor assembly accurately delivers the display panel to the machine's limiting base, completing the loading and positioning at the laser repair station.

[0018] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0019] Currently, when repairing defective display panels, the panels are typically moved to a support platform manually. However, due to the large size of the display panels, manual handling is time-consuming and labor-intensive, making it difficult to quickly and accurately adjust the position of the display panels, thus affecting the overall repair efficiency.

[0020] Therefore, this application creatively proposes a laser repair platform for display panels. The platform includes a first conveying component, a second conveying component, and a machine base arranged sequentially along the display panel conveying direction. The machine base is equipped with a limiting base for supporting and positioning the display panel, and an elastic bearing structure is provided on one side of the machine base. When display panel repair is required, the display panel is first placed onto the conveying surface of the first conveying component manually or by a robotic arm. Because the starting end of this conveying surface is relatively low, this design significantly reduces the labor intensity and handling time for operators. Subsequently, the first conveying component conveys the display panel to the second conveying component. As the panel transfers between the two, it naturally falls due to the height difference between the conveying surfaces; at this time, the elastic bearing structure provides stable support for the falling display panel, allowing it to gently and smoothly transition onto the conveying surface of the second conveying component. Finally, the second conveying component accurately conveys the display panel to the limiting base of the machine base, completing the loading and positioning at the laser repair station.

[0021] The present application will be specifically described below through specific embodiments.

[0022] Reference Figures 1 to 6 As shown in the figure, this application embodiment provides a laser repair platform for display panels. The repair platform includes a first conveying component 1, a second conveying component 2, and a machine base 3 arranged sequentially along the conveying direction of the display panel. The machine base 3 is provided with a limiting base 4 for carrying and positioning the display panel. The starting end of the first conveying component 1 is inclined downward, and the second conveying component 2 is arranged horizontally, with its end docking with the limiting base 4, for conveying the display panel onto the limiting base 4. An elastic bearing structure 5 is provided on one side of the machine base 3. The bearing end of the elastic bearing structure 5 protrudes vertically from the conveying surface of the second conveying component 2, for receiving the display panel conveyed by the first conveying component 1. When the display panel moves completely above the second conveying component 2, its gravity presses down on the bearing end, causing the bearing end to descend to a position no higher than the upper surface of the second conveying component 2.

[0023] In this embodiment, both the first conveying component 1 and the second conveying component 2 are conveyor belts. It should be noted that conveyor belts with excellent insulation / antistatic properties should be given priority, and proper grounding should be planned to avoid damage to the display panel due to frictional static electricity during the conveying process. The specific implementation method is the prior art and will not be described in detail here.

[0024] In some examples, the machine tool 3 is rectangular to facilitate its processing and design, as well as to facilitate the receiving of the display panel from the second conveyor assembly 2. Of course, the machine tool 3 can also be a regular shape such as a cylinder, or any other irregular shape, as long as the above conditions are met.

[0025] Understandably, the tilt angle of the first conveying component 1 can be determined by comprehensively considering factors such as its own conveying force, the size of the space, and the size of the display panel. Generally, in order to facilitate the smooth conveying of the display panel, the tilt angle of the first conveying component 1 is usually relatively large, which results in a smaller angle between the conveying surface of the first conveying component 1 and the ground.

[0026] In addition, to facilitate the transport of the display panel, a baffle is usually installed at the starting end of the first transport component 1 to prevent the display panel from sliding down when the first transport component 1 is not in operation.

[0027] Specifically, when display panel repair is required, the display panel is first placed onto the conveying surface of the first conveying component 1 manually or by a robotic arm. Because the starting point of this conveying surface is low, this design significantly reduces the labor intensity and handling time for operators. Subsequently, the first conveying component 1 conveys the display panel to the second conveying component 2. As the panel moves between the two, it naturally falls due to the height difference between the conveying surfaces; at this time, the elastic support structure 5 provides stable support for the falling display panel, allowing it to gently and smoothly transition onto the conveying surface of the second conveying component 2. Finally, the second conveying component 2 accurately conveys the display panel to the limiting base 4 of the machine tool 3, completing the loading and positioning at the laser repair station.

[0028] Furthermore, in some examples, refer to Figure 1 As shown, the limiting base 4 includes at least one limiting member 41, and the limiting member 41 includes two oppositely arranged seats 411, each seat 411 extending along the conveying direction of the display panel; each seat 411 also extends upward in the vertical direction to form a limiting body 412, and a limiting space 413 for limiting the movement of the display panel is formed between the two oppositely arranged limiting bodies 412.

[0029] It can be understood that the number of limiting components 41 can be two or more, and can be flexibly adjusted according to the size of the machine base 3 and design requirements. In this embodiment, the limiting base 4 includes one limiting component 41.

[0030] In addition, in some examples, the limiting member 41 is detachably connected to the machine base 3 so that the limiting member 41 can be flexibly disassembled and assembled according to process requirements.

[0031] In this embodiment, refer to Figure 1 and Figure 3 As shown, the base 411 and the limiting body 412 are integrally formed and are L-shaped. The top surface of the base 411 serves as a bearing surface, and its surface can be smoothed to reduce wear on the display panel. The side of the limiting body 412 facing the limiting space 413 serves as a limiting surface, used to abut against the side of the display panel, thereby reducing the possibility of accidental movement of the display panel during the repair process.

[0032] Furthermore, in some examples, refer to Figure 1 and Figure 3 As shown, each limiting body 412 is provided with at least two adjustment holes 4121 along its extension direction, and each adjustment hole 4121 is provided with a movable abutment post 4122, which is used to abut against the side of the display panel.

[0033] Specifically, since the size of the display panel may vary, when the width of the display panel is less than the width of the limiting space 413, the abutment post 4122 is moved so that it gradually enters the limiting space 413 and abuts against the side of the display panel. Additionally, in some cases, such as when the display panel needs to be tilted for repair, the abutment post 4122 can be moved to push one side of the display panel, causing it to tilt.

[0034] Furthermore, in some examples, refer to Figure 4 As shown, the end of the abutting post 4122 facing the limiting space 413 is provided with an abutting panel 4123, and the side of the limiting body 412 facing the limiting space 413 is provided with a receiving groove 4124 for accommodating the abutting panel 4123.

[0035] Specifically, the abutment panel 4123 is designed so that when a narrow display panel is pressed, it directly contacts the side of the display panel. Compared to the abutment post 4122 itself, its larger contact area can distribute the pressure applied to the display panel, avoiding excessive local pressure and providing more uniform support, effectively preventing the display panel from shaking or shifting within the limiting space 413. Simultaneously, for narrow display panels, the abutment panel 4123 can compensate for any insufficient limiting due to the reduced panel size. Even with a narrow panel, the abutment panel 4123 ensures sufficient area for stable contact, enhancing the adaptability of the limiting structure to display panels of different sizes. Furthermore, when the abutment panel 4123 is not needed, it can be moved into the receiving groove 4124 by moving the abutment post 4122, preventing the abutment panel 4123 from interfering with the display panel when the limiting body 412 is limiting it.

[0036] Furthermore, in some examples, refer to Figure 1 , Figure 2 and Figure 5 As shown, the second conveying assembly 2 has an installation space 21 extending vertically through it; the elastic bearing structure 5 includes a mounting plate 51 and an elastic component 52 mounted on the mounting plate 51. The elastic component 52 includes at least two elastic elements 521 arranged linearly along the conveying direction of the display panel. The bearing end of each elastic element 521 protrudes vertically from the conveying surface of the second conveying assembly 2, and along the conveying direction of the display panel, the bearing end of each elastic element 521 gradually rises or gradually rises and then gradually decreases; the mounting plate 51 is located below the second conveying assembly 2 and is connected to the machine base 3.

[0037] It is understandable that the elastic bearing structure 5 is generally located on the side of the machine base 3 near the first conveying component 1, so as to facilitate the installation and design of the elastic bearing structure 5.

[0038] Specifically, when the panel begins to fall, its end closest to machine 3 (the falling end) is relatively higher. At this time, the elastic elements 521, pre-set on this side with a specific height, will contact the panel first. These elastic elements 521 can effectively support the falling end of the panel, preventing vibration or stress caused by sudden hard impact. As the panel continues to fall, the higher elastic elements 521 will be compressed preferentially under the panel's gravity. At the same time, the other end of the panel gradually approaches the surface of the second conveying assembly 2 and begins to compress the lower elastic elements 521 on that side. By precisely designing the initial height and elastic coefficient of the elastic elements 521 at different positions, the higher elastic elements 521 can be compressed first, and the lower elastic elements 521 can be compressed later, thus forming an effective "straightening" torque on the panel. This process can significantly reduce the tilt angle of the panel, guiding it from a tilted state to a near-horizontal state, and finally smoothly adhering to the conveying surface of the second conveying assembly 2. After successful and stable leveling, the panel can be precisely conveyed to the limiting base 4 by the second conveying component 2 with minimal vibration and excellent horizontal posture.

[0039] Furthermore, refer to Figure 6 As shown, the elastic element 521 includes a connecting part 5211, a deformable part 5212, and a bearing part 5213 arranged sequentially in the vertical direction; the connecting part 5211 is connected to the mounting plate 51, and the deformable part 5212 can drive the bearing part 5213 to move in the vertical direction after being pressed, so as to drive the bearing part 5213 into and out of the mounting space 21; wherein, the top surface of the bearing part 5213 is a smooth curved surface.

[0040] Each of the bearing components 5213 forms a bearing end.

[0041] In this embodiment, the deformable part 5212 is a cylindrical spring. By setting cylindrical springs with different elastic coefficients and lengths, the height of the supporting part 5213 and the compression time and degree of compression of the elastic element 521 can be flexibly adjusted. Furthermore, by setting the top surface of the supporting part 5213 as a smooth curved surface, friction on the display panel is reduced.

[0042] In some examples, the machine base 3 has a guide rail module on the side facing the first conveying component 1. The mounting plate 51 is slidably connected to the machine base 3 through the guide rail module to adjust the position of the elastic bearing structure 5 in the conveying direction of the display panel. By moving the mounting plate 51, the height of each elastic element 521 can be further adjusted flexibly to adapt to the technical requirements of conveying the display panel.

[0043] In some examples, refer to Figure 1As shown, the limiting base 4 is provided with a guide structure 6 on the side near the second conveying component 2. The guide structure 6 includes two oppositely arranged guide bars 61, and a guide space 62 is formed between the two guide bars 61 for guiding the movement of the display panel. The guide space 62 is wider at the end near the second conveying component 2 and narrower at the end near the limiting base 4, and is funnel-shaped.

[0044] By setting up the guide structure 6, when the display panel enters the guide space 62 formed by two opposing guide bars 61, its posture is gradually guided and corrected. This funnel-shaped space design can exert a physical constraint on the panel from wide to narrow, causing it to automatically center and adjust to a standard horizontal posture during transportation, thereby ensuring that the panel can smoothly enter the laser repair station with a precise posture. In this embodiment, the conveying surface of the second conveying component 2 is flush with the bearing surface of the limiting base 4. This allows for a seamless transition of the display panel between the two, effectively preventing jamming, vibration, or panel damage caused by height differences. A ramp can be provided at the starting end of the limiting base 4 to facilitate the conveying of the display panel onto the limiting base 4. To further optimize the loading experience, a guide ramp can be provided at the starting end of the limiting base 4 (i.e., the end closest to the second conveying component 2). This ramp significantly reduces the resistance when the panel enters the limiting base 4, providing smooth guidance and allowing the panel to reach the designated position more smoothly and accurately.
