[0002] In today's electronic information age, displays play a vital role in various electronic devices, such as smartphones, tablets, computer monitors, and televisions. As display technology continues to advance, performance indicators such as resolution, color rendering, and refresh rate continue to improve. This, in turn, places higher demands on quality control during the display production process. Display defect detection has become a critical step in ensuring product quality.
[0003] In current technology, all test bottles need to be tested before leaving the factory. Traditional display defect detection methods often rely on manual visual observation. With the development of science, some automated testing equipment is gradually being used for testing. However, these early automatic testing equipment have deficiencies in detection precision and accuracy. At the same time, these devices cannot be applied to different types of display screens for testing, which is not convenient for actual use.
[0004] Therefore, a device for detecting defects in a detection screen is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Example 1: Please refer to Figure 1-5The utility model provides a technical solution: a device for detecting screen defects, including a device body 1 and a detection component body, a groove 5 is opened inside the device body 1, a cover 6 is installed above the inner wall of the groove 5, and guide plates 7 are installed on the left and right sides of the lower inner wall of the groove 5, a threaded rod 8 is rotatably installed inside the left guide plate 7, a limit rod 9 is installed inside the right guide plate 7, a mounting plate 11 is threadedly installed on the rod wall of the threaded rod 8, a first motor 10 is installed at one end of the threaded rod 8, the first motor 10 is installed on the device body 1, and one side of the mounting plate 11 is slidably installed. On the limit rod 9, the main shaft 12 is installed in the internal rotation of the mounting plate 11, the second motor 13 is installed at the lower end of the main shaft 12, and the mounting platform 14 is installed at the upper end of the main shaft 12. The bottom of the mounting platform 14 is provided with a clamping mechanism, which drives the mounting plate 11 and the elastic clamping plate 19 to move outside the equipment to pick up the inspection product by controlling the rotation of the threaded rod 8, and drives the elastic clamping plates 19 on both sides to clamp the material and move it to the bottom of the inspection head 4 by controlling the rotation of the bidirectional screw 17, and cooperates with the rotation of the main shaft 12 to change the product inspection angle, thereby realizing comprehensive inspection with high inspection accuracy.
[0025] like Figure 2 As shown, the main body of the detection component includes a cylinder 2, which is installed on the cylinder 2. A detection device 3 is installed at the output end of the cylinder 2, and a detection head 4 is installed at the bottom of the detection device 3. The detection is performed by controlling the cylinder 2 to push the detection head 4 up and down.
[0026] like Figure 3 and 4 As shown, the clamping mechanism includes two fixing plates 15, both of which are slidably mounted inside the mounting platform 14, and a bidirectional screw 17 is commonly threadedly mounted inside the two fixing plates 15. The two ends of the bidirectional screw 17 are rotatably mounted with a hollow plate 16. The fixing plates 15 can adjust the spacing under the action of the bidirectional screw 17, and can fix display screens of different sizes, thereby improving the versatility of the device. The hollow plate 16 is mounted on the mounting platform 14, and one end of the bidirectional screw 17 passes through one side of the inner wall of the hollow plate 16 and is installed with a third motor 18. An elastic clamping plate 19 is provided on one side of the two fixing plates 15. The design of the elastic clamping plate 19 can play a buffering role when clamping the display screen, thereby reducing possible damage to the display screen.
[0027] A concave block 20 is installed on one side of the two fixed plates 15, and a buffer spring 21 is installed inside the two concave blocks 20. A fixed block 22 is installed on the other end of the two buffer springs 21. The two fixed blocks 22 are slidably installed inside the corresponding concave blocks 20 respectively, and the two elastic clamps 19 are installed on the corresponding fixed blocks 22 respectively. The concave blocks 20, buffer springs 21 and fixed blocks 22 are arranged between the elastic clamps 19 on both sides. The force generated in the process of clamping the material acts on the fixed block 22, and the buffer spring 21 is pushed by the fixed block 22 to shrink and buffer inside the concave block 20, thereby further preventing the problem of damage to the material being picked up.
[0028] The working principle is as follows: when the present invention is actually used, the display screen to be inspected is first placed on the mounting platform 14, the third motor 18 is started, and the bidirectional screw 17 is driven to rotate. The rotation of the bidirectional screw 17 causes the two fixing plates 15 to slide inside the mounting platform 14. Because it is a bidirectional screw 17, the two fixing plates 15 will move toward or away from each other. As the fixing plates 15 move, the two elastic clamping plates 19 approach and clamp the display screen to fix the display screen and prevent displacement during the inspection process. The second motor 13 works to drive the main shaft 12 to rotate. The rotation of the main shaft 12 drives the mounting platform 14 to rotate, thereby driving the clamped display screen to rotate. In this way, the inspection angle of the display screen can be adjusted so that the inspection head 4 can fully inspect all parts of the display screen. The cylinder 2 starts to move, pushing the inspection device 3 to move downward, and the inspection The detection head 4 at the bottom of the detection device 3 is close to the display screen to perform detailed defect detection on the display screen. During the detection process, the light cover 23 on one side of the inner wall of the device body 1 plays a lighting role, and the fill light 25 provides the light required for detection. The fourth motor 26 drives the soft light cover 24 to rotate, thereby adjusting the angle and range of the lighting to ensure that the detection area has uniform and appropriate light, thereby improving the accuracy of the detection. The mounting plate 11 moves under the coordinated action of the threaded rod 8 and the limit rod 9. When the threaded rod 8 rotates, because the mounting plate 11 is threadedly connected to the threaded rod 8, and one side of the mounting plate 11 is slidably installed on the limit rod 9, the mounting plate 11 will move up and down along the guide plate 7. The movement of the mounting plate 11 drives the mounting platform 14 and the display screen to move, thereby changing the detection position, thereby realizing the detection of different parts of the display screen.
[0029] Example 2: Figure 4 and 5As shown, in order to further improve the detection accuracy of the equipment, a light cover 23 is installed on one side of the inner wall of the equipment body 1, and a soft light cover 24 is rotatably installed inside the light cover 23. A fill light 25 is installed inside the soft light cover 24, and a fourth motor 26 is installed at one end of the soft light cover 24. The fourth motor 26 is installed on the light cover 23. By controlling the fourth motor 26 to drive the soft light cover 24 to rotate inside the light cover 23, the intensity of the light emitted by the fill light 25 is changed, and by changing the color of the light source fill light 25, the detection operation can be adapted to different types of display screens and detection environments.
