[0001] The utility model belongs to the technical field of display device manufacturing, and particularly relates to a thermal spraying device for repairing an OLED manufacturing device. Background Technique

[0002] OLED is an organic light-emitting diode. The organic light-emitting diode display technology has advantages such as low voltage, wide viewing angle, fast response speed, and good temperature adaptability. It is a new generation of display technology and has been widely used. The market demand is increasing day by day. During the manufacturing process of an OLED display screen, it is easy to cause corrosion and wear of metal components. Since the OLED display screen has high requirements for the sealing performance and stability of manufacturing equipment, once the components of the manufacturing device are severely corroded and worn, it will lead to the degradation or even damage of the OLED display screen, resulting in defects. And replacing the entire device has a high cost and a long production cycle. Therefore, a thermal spraying device for repairing the manufacturing equipment is needed.

[0003] When the existing thermal spraying device is in use, the workpiece to be sprayed is usually placed on the spraying table, and then the workpiece is pushed to pass through the spraying area to complete spraying. However, the existing thermal spraying device has a single structure and often relies on manual labor to push the workpiece to move. The moving speed and path of the workpiece pushed by manual labor during spraying may be inconsistent, resulting in unstable quality and uniformity of the spraying result, and uneven thickness of the coating on the workpiece surface, reducing the quality of thermal spraying repair.

[0004] Therefore, a thermal spraying device for repairing an OLED manufacturing device is needed to solve the problem that the quality of thermal spraying repair is reduced due to manual pushing of the workpiece in the prior art. Summary of the Utility Model

[0007] It should be noted that shock-absorbing sleeves are fixedly connected to the bottoms of the plurality of support columns.

[0008] Furthermore, it is worth noting that the positioning mechanism includes two through grooves opened in the workbench, rotating shafts are rotatably connected to the front and rear ends of the inner walls of the two through grooves, mounting sleeves are fixedly connected to the outer walls of the two rotating shafts, first connecting rods are fixedly connected to the tops of the two mounting sleeves, fixing clamping plates are installed on the inner sides of the two first connecting rods, second connecting rods are fixedly connected to the bottoms of the two mounting sleeves, and a double-acting cylinder corresponding to the two second connecting rods is fixedly connected to the bottom of the workbench.

[0009] Even further, it should be noted that the fixing clamping plate is installed on the inner side of the first connecting rod through a universal joint.

[0010] As a preferred implementation manner, the two output ends of the double-acting cylinder are respectively rotatably connected to the two second connecting rods.

[0013] Compared with the prior art, a thermal spraying device for repairing an OLED manufacturing device provided by the present utility model has at least the following beneficial effects:

[0014] (1) By setting a servo motor to drive the rotation of a threaded rod, with the cooperation of a guide sleeve and a ball nut seat, the convex frame drives the raw material storage box and the hot melt spray head to move.

Detailed Description of the Embodiment

[0022] The following further describes the present utility model in conjunction with embodiments.

[0023] Please refer to Figures 1 - 5, the present utility model provides a thermal spraying device for repairing an OLED manufacturing device, which includes a workbench 1. A plurality of support columns 2 are fixedly connected to the bottom of the workbench 1. Positioning mechanisms 3 are arranged at positions near the front and rear ends of the top of the workbench 1. Two first support plates 4 are fixedly connected to a position near one side of the top of the workbench 1. Two second support plates 5 are fixedly connected to a position near the other side of the top of the workbench 1. A guide column 6 is fixedly connected between the two first support plates 4. A threaded rod 7 is rotatably connected between the two second support plates 5. A guide sleeve 8 is slidably connected to the outer wall of the guide column 6. A ball nut seat 9 is rotatably connected to the outer wall of the threaded rod 7. A convex frame 10 is fixedly connected to the outer walls of the guide sleeve 8 and the ball nut seat 9. A servo motor 11 is installed at the rear end of one of the second support plates 5. A raw material storage box 12 is fixedly connected to the top of the convex frame 10. A plurality of thermal spraying nozzles 13 communicated with the raw material storage box 12 are installed at the bottom of the convex frame 10.

[0024] Further, as shown in Figure 1 , Figure 2 and Figure 3 It is worth specifically explaining that shock-absorbing sleeves are fixedly connected to the bottoms of the plurality of support columns 2. The shock-absorbing sleeves can effectively reduce the vibration transmission from the machine operation to the support columns 2 during operation, thereby reducing the impact on the thermal spraying device, ensuring the stability and accuracy of the equipment. At the same time, by reducing vibration interference, the shock-absorbing sleeves can improve the stability of the spraying process, ensure the uniformity and consistency of spraying, and thus improve the repair quality.

[0025] Further, as shown in Figure 1 , Figure 2 and Figure 3 It is worth specifically explaining that the output end of the servo motor 11 penetrates through the second support plate 5 and is fixedly connected to the threaded rod 7, ensuring that the servo motor 11 can drive the threaded rod 7 to rotate smoothly, thereby providing driving force for the uniform movement of the thermal spraying nozzles 13.

[0026] Further, as shown in Figure 1 , Figure 2 and Figure 3 It is worth specifically explaining that electromagnetic valves are installed inside the plurality of thermal spraying nozzles 13. The electromagnetic valves can precisely control the flow rate and spraying rate of the molten material, thereby achieving higher-precision spraying. Operators can adjust the output of the material according to the repair requirements to ensure that the repair effect meets the expectations. Through the precise control of the electromagnetic valves, the non-uniformity of the material during the spraying process can be reduced, and the uniformity and consistency of the repair layer can be improved.

[0027] According to the above working process, it can be known that by setting the servo motor 11 to drive the threaded rod 7 to rotate, with the cooperation of the guide sleeve 8 and the ball nut seat 9, the convex frame 10 drives the raw material storage box 12 and the hot melt spray head 13 to move. The hot melt spray head 13 moves at a constant speed to perform thermal spraying repair on the manufacturing device on the top of the workbench 1, replacing the traditional manual pushing of the workpiece to move. The precise control of the servo motor 11 improves the accuracy and repeatability of the workpiece movement, reduces the errors caused by manual operation, and the constant speed movement of the hot melt spray head 13 ensures the uniformity and consistency of the sprayed coating, improving the repair quality.

[0028] Furthermore, as Figure 4 and Figure 5 shown, it is worth specifically stating that the positioning mechanism 3 includes two through grooves 301 opened inside the workbench 1. The front and rear ends of the inner walls of the two through grooves 301 are rotatably connected with rotating shafts 302. The outer walls of the two rotating shafts 302 are fixedly connected with mounting sleeves 303. The tops of the two mounting sleeves 303 are fixedly connected with first connecting rods 304. Fixed clamping plates 305 are installed inside the two first connecting rods 304. The bottoms of the two mounting sleeves 303 are fixedly connected with second connecting rods 306. A double-acting cylinder 307 corresponding to the two second connecting rods 306 is fixedly connected to the bottom of the workbench 1. By setting the positioning mechanism 3, the two fixed clamping plates 305 clamp and fix the manufacturing device to be repaired, reducing the movement or vibration of the workpiece during the spraying process and ensuring that the spraying quality is uniform and stable.

[0029] Furthermore, as Figure 4 and Figure 5 shown, it is worth specifically stating that the fixed clamping plate 305 is installed inside the first connecting rod 304 through a universal joint. The universal joint allows the fixed clamping plate 305 to be finely adjusted in multiple directions, so as to be able to adapt to manufacturing devices to be repaired with different sizes and shapes, providing greater flexibility and adaptability to handle various workpieces. At the same time, through the adjustment of the universal joint, the fixed clamping plate 305 can fit more closely to the surface of the workpiece, ensuring the stability of the clamping and avoiding the movement or detachment of the workpiece during the repair process.

[0030] Furthermore, as Figure 4 and Figure 5 shown, it is worth specifically stating that the two output ends of the double-acting cylinder 307 are respectively rotatably connected with the two second connecting rods 306, ensuring that the double-acting cylinder 307 can drive the two second connecting rods 306 to move outward simultaneously, thereby providing a driving force for the clamping of the fixed clamping plate 305.

[0031] This solution has the following working process: During actual use, place the manufacturing device to be repaired on the top of the workbench 1. Open the double-acting cylinder 307. The output end of the double-acting cylinder 307 drives the two second connecting rods 306 to move outward simultaneously. With the cooperation of the rotating shaft 302 and the mounting sleeve 303, the two first connecting rods 304 move inward simultaneously, so that the two fixed clamping plates 305 clamp and fix the manufacturing device to be repaired. Then, turn on the servo motor 11 to drive the threaded rod 7 to rotate. With the cooperation of the guide sleeve 8 and the ball nut seat 9, the convex-shaped frame 10 drives the raw material storage box 12 and the hot melt spray head 13 to move. Open the hot melt spray head 13 that moves at a constant speed to perform thermal spraying repair on the manufacturing device on the top of the workbench 1.

[0032] In summary: By setting the servo motor 11 to drive the threaded rod 7 to rotate, with the cooperation of the guide sleeve 8 and the ball nut seat 9, the convex-shaped frame 10 drives the raw material storage box 12 and the hot melt spray head 13 to move. The hot melt spray head 13 moves at a constant speed to perform thermal spraying repair on the manufacturing device on the top of the workbench 1, replacing the traditional manual pushing of the workpiece to move. The precise control of the servo motor 11 improves the accuracy and repeatability of the workpiece movement, reduces the errors caused by manual operation. The constant-speed movement of the hot melt spray head 13 ensures the uniformity and consistency of the spray coating, improving the repair quality; By setting the positioning mechanism 3, the two fixed clamping plates 305 clamp and fix the manufacturing device to be repaired, reducing the movement or vibration of the workpiece during the spraying process, ensuring that the spraying quality is uniform and stable.
