Description

Technical Field

[0001] This invention relates to the field of photographic inspection technology, and more specifically, to a device for detecting holes in polarizers. Background Technology

[0002] Polarizing film is a key optical component of LCD screen. Its function is to filter out stray light and form a clear image. To ensure its quality, strict hole inspection must be carried out during the production process. This inspection usually uses high-resolution cameras and intelligent image algorithms to automatically identify micron-level hole defects on the surface, thereby effectively preventing defects such as bright spots and dark spots from appearing on the screen and ensuring the excellent display effect of the final product.

[0003] A patent application with publication number CN112903705B discloses a polarizer hole detection device, including a base. A bracket is fixedly connected to the upper end of the base. A conveying panel is slidably connected to the inner cavity of the bracket. A rotating disk is rotatably connected to the top of the inner cavity of the bracket. A telescopic mechanism is fixedly connected to the lower end of the rotating disk. Connecting pins are evenly connected to the lower end of the telescopic mechanism. Positioning rings are fixedly connected to the periphery of the connecting pins. Limiting frames are evenly inserted into the positioning rings. This polarizer hole detection device uses the telescopic mechanism to send each detection wheel into the hole cavity. The rotating disk drives the detection wheels to perform circular motion, ensuring that the detection wheels are pressed tightly against the inner wall of the hole with appropriate pressure. This causes the adjusting spring to be compressed by the guide block. When the guide block reciprocates, it coordinates with a corresponding warning mechanism, thereby facilitating rapid and comprehensive detection of polarizer holes and improving the corresponding detection accuracy.

[0004] During the use of the aforementioned device, impurities may adhere to the polarizer due to production and static electricity. It is necessary to remove the fine particles adhering to the polarizer. However, directly using a brush or adhesive structure to treat the polarizer can easily cause scratches, which may damage the polarizer during the testing process. Summary of the Invention

[0015] As a further optimization of the present invention, the maximum distance between the extrusion cleaning members on the two first limiting plates is greater than the length of the first connecting plate.

[0016] The beneficial effects of this invention are as follows: The polarizer hole detection device of the present invention cleans the surface of a first polarizer by means of multiple extrusion cleaning components inside the extrusion device. The multiple extrusion cleaning components are connected by a second connector, and a first limiting plate is connected by a first connector. This ensures that the extrusion cleaning components do not cause extrusion or pulling damage to the surface of the first polarizer during cleaning, thereby improving the safety of the device during cleaning. The first limiting plate is limited by the adjusting component and the limiting component to prevent the extrusion cleaning components from springing back after cleaning. At the same time, it allows the first polarizer to be laid flat on the conveyor belt, preventing the problem of blind spots in camera photography. Attached Figure Description

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] like Figures 1 to 3 As shown in the figure, a polarizer hole detection device according to an embodiment of the present invention includes a transmission frame 1, a conveyor belt 11 on the transmission frame 1, a first polarizer 13 on the conveyor belt 11, a limiting frame 12 placed on the conveyor belt 11, a support block 14 fixedly installed on the top of the transmission frame 1, a first telescopic rod 15 fixedly installed at the center of the support block 14, a camera 16 installed at the bottom of the first telescopic rod 15, and a pressing device 2 installed outside the first telescopic rod 15. The camera 16 is used to photograph the limiting frame 12 on the conveyor belt 11, and the pressing device 2 is used to adhere and roll impurities on the top of the limiting frame 12. like Figures 4 to 6As shown, the extrusion device 2 includes a first connecting plate 21, a first limiting plate 22, an extrusion cleaning component 23, a collecting component 24, an adjusting component 25, a limiting component 26, a first mounting plate 27, a first connecting component 28, and a second connecting component 29. The first connecting plate 21 is fixedly installed at the bottom of the first telescopic rod 15. The first mounting plate 27 is provided at the lower part of the first connecting plate 21. The first limiting plate 22 is rotatably installed on the first mounting plate 27. A plurality of extrusion cleaning components 23 are provided at the end of the first limiting plate 22. A space is provided between the first limiting plate 22 and the extrusion cleaning components 23. There is a first connecting member 28, and a second connecting member 29 is provided between the two extrusion cleaning members 23. A collecting member 24 is fixedly installed on the side of the first limiting plate 22. Adjusting members 25 are symmetrically installed on the first connecting plate 21. A limiting member 26 is connected to the adjusting member 25. When the first telescopic rod 15 extends, the extrusion cleaning member 23 approaches the first polarizer 13. Then, the extrusion cleaning members 23 on the two first limiting plates 22 are forced to move away from each other, thereby adhering the impurities on the surface of the first polarizer 13. The limiting member 26 is used to limit the first limiting plate 22.

[0021] It should be noted that the first polarizer 13 is placed on the conveyor belt 11, located at the position of the limiting frame 12. When the first polarizer 13 moves directly below the first telescopic rod 15, the first telescopic rod 15 is activated, driving the extrusion device 2 to move closer to the first polarizer 13. Multiple extrusion cleaning components 23 contact the top of the first polarizer 13. The first telescopic rod 15 continues to extend, thereby moving the multiple extrusion cleaning components 23 on the two first limiting plates 22 away from each other, thus cleaning the top of the first polarizer 13. A collecting component 24 is provided between the first limiting plates 22 to scrape off impurities adhering to the surface of the extrusion cleaning components 23. When the two first limiting plates 22 are fully open, the adjusting components 25 move away from each other. At this time, the limiting component 26 limits the direction of the first limiting plates 22 through the two adjusting components 25. Then, the camera 16 is activated to take a picture. After the picture is taken, the first telescopic rod 15 is activated to drive the extrusion device 2... When the pressure cleaning components 23 on the two first limiting plates 22 are raised, the cleaning work is completed. The multiple pressure cleaning components 23 are connected by the second connector 29, so that the impurities adhering to the pressure cleaning components 23 will not scratch the surface of the first polarizer 13 or cause excessive pressure, thus improving the safety of the first polarizer 13 under the detection of the camera 16. This device cleans the surface of the first polarizer 13 through multiple pressure cleaning components 23, which are connected by the second connector 29. The first limiting plate 22 is connected by the first connector 28, so that the pressure cleaning components 23 will not cause pressure and pulling damage to the surface of the first polarizer 13 during cleaning, thereby improving the safety of the device during cleaning. The first limiting plate 22 is limited by the adjusting component 25 and the limiting component 26 to prevent the pressure cleaning components 23 from rebounding after cleaning. At the same time, it allows the first polarizer 13 to be laid flat on the conveyor belt 11, preventing the camera 16 from having blind spots when taking pictures.

[0022] like Figures 3 to 4 As shown, the first connecting member 28 includes a first connecting block 281 rotatably mounted on the end of the first limiting plate 22. A first rotating block 282 is rotatably mounted inside the first connecting block 281. A third telescopic rod 283 is fixedly mounted on the side of the first rotating block 282. A first U-shaped block 285 is fixedly mounted on the end of the third telescopic rod 283. A first limiting spring 284 is fixedly mounted on the side of the first U-shaped block 285. The first limiting spring 284 is sleeved on the outside of the third telescopic rod 283. The end of the first U-shaped block 285 is connected to the extrusion cleaning member 23.

[0023] It should be noted that the third telescopic rod 283 can adaptively adjust its height during the rotation of the extrusion cleaning component 23, preventing impurities on the surface of the first polarizer 13 from causing extrusion scratches and improving the safety of the inspection.

[0024] like Figures 3 to 4 As shown, the extrusion cleaning component 23 includes an extrusion connecting plate 233 rotatably mounted on the end of the first U-shaped block 285. An extrusion mounting plate 232 is fixedly mounted on the outside of the extrusion connecting plate 233. A rubber extrusion cleaning ring 231 is fixedly mounted on the outside of the extrusion mounting plate 232. The extrusion connecting plate 233 is symmetrically arranged about the extrusion mounting plate 232. A second connector 29 is rotatably mounted on the outside of the extrusion connecting plate 233 on the side away from the first connector 28. Multiple extrusion cleaning components 23 are connected through the second connector 29.

[0025] It should be noted that the multiple extrusion cleaning components 23 are in contact with each other, so that the extrusion cleaning components 23 can be raised and lowered adaptively, preventing the extrusion cleaning components 23 from causing abrasions during cleaning. In addition, the multiple extrusion cleaning components 23 extrude the surface of the first polarizer 13, so that the first polarizer 13 can be laid flat on the surface of the conveyor belt 11, improving the accuracy of the camera 16 when taking pictures and detecting.

[0026] like Figures 3 to 4 As shown, the second connector 29 includes a second U-shaped block 291 rotatably mounted on the outside of the extrusion connecting plate 233, a fourth telescopic rod 292 fixedly mounted on the side of the second U-shaped block 291, a third U-shaped block 294 fixedly mounted on the end of the fourth telescopic rod 292, and a third connecting spring 293 provided on the outside of the fourth telescopic rod 292.

[0027] It should be noted that the fourth telescopic rod 292 and the third telescopic rod 283 have the same function, so that when the rubber extrusion cleaning ring 231 cleans the surface of the first polarizer 13, it can prevent impurities on the surface of the first polarizer 13 from adhering to the surface of the rubber extrusion cleaning ring 231 and causing a large extrusion problem on the surface of the first polarizer 13, and at the same time prevent the extrusion cleaning part 23 from slipping and scratching.

[0028] like Figure 3 and Figure 5 As shown, the adjusting component 25 includes an adjusting slider 251 slidably mounted on the side of the first connecting plate 21 and symmetrically arranged. A second telescopic rod 252 is fixedly mounted on the bottom of the adjusting slider 251. A limit adjusting block 254 is fixedly mounted on the end of the second telescopic rod 252. A first protrusion 253 is provided on the side of the first limiting plate 22. The limit adjusting block 254 is sleeved on the outside of the first protrusion 253.

[0029] It should be noted that when the two first limiting plates 22 move away from each other, the two adjusting sliders 251 are equipped with a gear structure similar to an automatic door opening mechanism, which makes the two adjusting sliders 251 equidistant from the center. Therefore, the adjusting sliders 251 can automatically move away or closer. The second telescopic rod 252, the first protrusion 253, and the limiting adjusting block 254 move away or closer synchronously. The adjusting slider 251 is connected to the limiting member 26, so the adjusting member 25 can be limited. This prevents the first telescopic rod 15 from rising and the squeezing cleaning member 23 from moving closer again when the squeezing cleaning member 23 moves to the maximum distance, thus affecting the camera 16's photo detection of the first polarizer 13.

[0030] like Figures 5 to 6 As shown, the limiting member 26 includes a limiting tube 261 fixedly installed on the side of the adjusting slider 251. A piston rod 264 is slidably installed inside the limiting tube 261. The end of the piston rod 264 is connected to another adjusting slider 251. The limiting tube 261 is provided with a first air hole 262 and a second air hole 263. A first limiting block 265 and a second limiting block 267 are fixedly installed on the top of the first connecting plate 21. A second limiting plate 268 is rotatably installed inside the second limiting block 267. A limiting inclined rod 266 is provided at the end of the second limiting plate 268. A hole is provided on the limiting tube 261 for the insertion of the limiting inclined rod 266. A second limiting spring 269 is fixedly installed on the lower part of the second limiting plate 268 on the side away from the limiting inclined rod 266. The second limiting spring 269 is used to limit the second limiting plate 268. A rod is slidably provided inside the first limiting block 265. The bottom of the rod contacts the top of the second limiting plate 268.

[0031] It should be noted that the limiting tube 261 and piston rod 264 are cylinder structures. When the piston rod 264 moves, it can pass over the limiting inclined rod 266, thereby limiting the extension distance of the limiting tube 261 and the limiting inclined rod 266. The surface of the limiting tube 261 is provided with a first air hole 262 and a second air hole 263. The diameter of the first air hole 262 is larger than the diameter of the second air hole 263. Therefore, when the piston rod 264 slides into the limiting tube 261, it can slow down the speed and prevent the problem of impact caused by the rapid reset of the squeezing cleaning part 23, thus improving the stability of the device operation. When the rod on the first limiting block 265 is squeezed by the first telescopic rod 15, it can drive the second limiting plate 268 to rotate, thereby causing the limiting inclined rod 266 to rise, allowing the piston rod 264 to reset and slide inside the limiting tube 261.

[0032] like Figures 7 to 8As shown, the collecting component 24 includes a collecting chamber 241 fixedly installed on the side of the first limiting plate 22. A door panel 242 is provided on the collecting chamber 241. A scraper 243 is provided on the side of the collecting chamber 241. A handle 244 is fixedly installed on the side of the door panel 242.

[0033] It should be noted that the scraper 243 can scrape and clean the impurities on the surface of the rubber extrusion cleaning ring 231, and then enter the interior of the collection chamber 241. If the collection chamber 241 needs to be cleaned, the door panel 242 can be opened by the handle 244 to clean the interior of the collection chamber 241.

[0034] like Figures 2 to 8 As shown, a torsion spring is provided at the connection position between the first mounting plate 27 and the first limiting plate 22.

[0035] It should be noted that a torsion spring is provided at the connection position between the first mounting plate 27 and the first limiting plate 22, so that the multiple extrusion cleaning parts 23 on the two first limiting plates 22 have a force that brings them closer to each other, so that when the extrusion cleaning parts 23 come into contact with the surface of the first polarizer 13, they can roll and extrude flatten the surface of the first polarizer 13.

[0036] like Figure 8 As shown, the bottom curvature of the scraper 243 is the same as the outer curvature of the extrusion cleaning component 23.

[0037] It should be noted that the bottom curvature of the scraper 243 is the same as the outer curvature of the extrusion cleaning component 23, so that the scraper 243 can contact the surface of the rubber extrusion cleaning ring 231, thereby improving the cleaning effect.

[0038] like Figures 5 to 8 As shown, the maximum distance between the extrusion cleaning members 23 on the two first limiting plates 22 is greater than the length of the first connecting plate 21.

[0039] It should be noted that the maximum distance between the extrusion cleaning parts 23 on the two first limiting plates 22 is greater than the length of the first connecting plate 21, so that the camera 16 can perform comprehensive photo detection on the surface of the first polarizer 13, preventing the problem of blind spots in the photo and improving the accuracy of the photo detection by the camera 16.

[0040] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the embodiments described above, all of which are within the protection scope of the present invention.
