Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and specifically relates to a visual detection device for flexible screen detection. Background Art

[0002] Flexible display technology, with its low power consumption, exceptional flexibility, and portability, is becoming the preferred display solution for mobile devices such as smartphones, tablets, and wearables. This technological innovation not only significantly increases screen size without sacrificing portability, but also significantly enhances user visual experience and interactive satisfaction. However, as flexible display market penetration continues to rise, quality control and inspection processes in the production process face unprecedented challenges.

[0003] Currently, mainstream display screen visual inspection equipment on the market is mostly designed around rigid screens. They rely primarily on fixtures such as brackets to secure the display, and mechanically rotate or move the inspection head to achieve comprehensive inspection of all angles of the screen. While this model performs well for rigid screen inspection, it struggles with the softness and deformation of flexible screens. The natural curvature of flexible screens and the difficulty of mechanical handling make traditional equipment difficult to effectively adapt, resulting in limited inspection accuracy. Furthermore, the system relies heavily on offline inspection processes requiring manual intervention, significantly reducing inspection efficiency and automation levels.

[0004] Therefore, we propose a visual inspection device for flexible screen inspection to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0034] The following will be combined with the accompanying 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.

[0035] See Figures 1-9 The utility model provides a visual inspection device for flexible screen detection, including a shockproof frame 1 and a flexible screen fixing mechanism 2 installed on the shockproof frame 1, the flexible screen fixing mechanism 2 includes two parallel first linear motors 201, and the two first linear motors 201 have relatively arranged clamping mechanisms 202 on the mover seats to keep the flexible screen in a tensioned state. The shockproof frame 1 is also equipped with an air float plate and a back inspection camera assembly 3 below between the two first linear motors 201. The shockproof frame 1 is sequentially equipped with an alignment assembly 4, a detection assembly 5 and a re-inspection assembly 6 along the transmission direction of the first linear motor 201, which are respectively used for the alignment, detection and re-inspection operations of the flexible screen.

[0036] The visual inspection equipment designed above can effectively adapt to the inspection requirements of flexible screens. The specific usage process is as follows:

[0037] First, the two ends of the flexible screen are respectively mounted on the clamping mechanisms 202 on the first linear motors 201 on both sides. Through the precise adjustment of the clamping mechanisms 202, the flexible screen is ensured to remain in a tensioned state and to achieve flatness of the flexible screen. Subsequently, the equipment is started, and the first linear motors 201 on both sides operate synchronously. The mover seats of the first linear motors 201 drive the clamping mechanisms 202 and the flexible screen on the clamping mechanisms 202 to move along a preset path. During this process, the flexible screen passes through the alignment component 4, the detection component 5 and the re-inspection component 6 in sequence, thereby completing the alignment, detection and re-inspection operations of the flexible screen in sequence. At the same time, the air float plate and the back inspection camera component 3 are also used to inspect the back of the flexible screen. By combining the front and back inspections, the flexible screen is comprehensively inspected from multiple angles, thereby improving the accuracy and reliability of the inspection. Throughout the entire inspection process, the clamping mechanism 202 always keeps the flexible screen flat during the inspection process, avoiding the inspection error caused by the bending of the screen, overcoming the difficulties faced by traditional equipment in inspecting flexible screens, and improving the adaptability and flexibility of the equipment. In addition, automated inspection operations significantly reduce manual intervention, which not only improves inspection efficiency but also effectively reduces human errors, ensuring that flexible screens can continue to meet high quality standards during the production process, further improving the overall quality and market competitiveness of the product.

[0038] In a specific embodiment, see Figure 8 and Figure 9 The clamping mechanism 202 is provided with a vacuum adsorption plate 2021, a pressing mechanism 2022, a flattening servo motor 2023, a pressing servo motor 2024 and an alignment servo motor 2025. The specific connection relationship is as follows:

[0039] The vacuum adsorption plate 2021 is mounted on the base surface of the clamping mechanism 202 and adsorbs the flexible screen through vacuum suction;

[0040] The pressing mechanism 2022 is installed above the vacuum adsorption plate 2021 and can be driven downward by the pressing servo motor 2024 to press the flexible screen onto the vacuum adsorption plate 2021;

[0041] The alignment servo motor 2025 is installed on one side of the clamping mechanism 202. The alignment servo motor 2025 is connected to an alignment roller and drives the alignment roller to move, thereby achieving precise alignment of the flexible screen placed on the clamping mechanism 202.

[0042] The clamping mechanism 202 is slidably connected to the mover seat of the first linear motor 201 and is connected via a flattening servo motor 2023 , thereby driving the flexible screen to stretch to one side and achieving flattening of the flexible screen.

[0043] The vacuum adsorption plate 2021 firmly adsorbs the flexible screen on the base surface of the clamping mechanism 202 through vacuum suction, ensuring the stability of the screen during the detection process and preventing dislocation or falling off due to movement or vibration. Driven by the clamping servo motor 2024, the clamping mechanism 2022 can accurately control the downward pressure and evenly press the flexible screen on the vacuum adsorption plate 2021, which not only further enhances the fixing effect of the flexible screen, but also effectively avoids wrinkles or deformation of the screen due to loosening during the detection process, thereby improving the detection accuracy. Through the cooperation of the alignment servo motor 2025 and the alignment roller, the alignment of the flexible screen can be achieved, providing a reliable premise guarantee for subsequent detection operations. In addition, the flattening servo motor 2023 controls the clamping mechanism 202 to slide on the mover seat of the first linear motor 201, thereby driving the flexible screen to stretch to one side. The flexible screen is flattened through the coordinated cooperation of the flattening servo motors 2023 on the clamping mechanisms 202 on both sides, which solves the detection problem caused by the natural bending of the flexible screen, ensures that the screen is always in a flat state during the detection process, and improves the accuracy and reliability of the detection.

[0044] In a specific embodiment, see Figure 7 The air floating plate and back inspection camera assembly 3 includes an ordinary air floating plate 301, a precision air floating plate 302, a crystal rod 303, a line scan camera 304, a first line light source 305 and a camera adjustment mechanism 306. The ordinary air floating plate 301 is installed in the non-detection area, the precision air floating plate 302 is installed in the detection area, the crystal rod 303 is installed in the precision air floating plate 302, and the upper and lower surfaces are precisely flush with the air floating plate. The first line light source 305 and the camera adjustment mechanism 306 are both installed below the precision air floating plate 302, and the line scan camera 304 is installed on the camera adjustment mechanism 306, which can realize the angle and position adjustment of the line scan camera 304.

[0045] The air-floating plate and back-inspection camera assembly 3 achieves defect detection on the back of the flexible screen through the coordinated operation of a standard air-floating plate 301, a precision air-floating plate 302, a crystal rod 303, a line scan camera 304, a first linear light source 305, and a camera adjustment mechanism 306. Specifically, the standard air-floating plate 301 is installed in the non-inspection area, serving as a base support platform, providing stable support and reducing the impact of external vibrations on the inspection process. The precision air-floating plate 302, installed in the inspection area, has higher precision and flatness requirements than the standard air-floating plate 301. It carries the core components of the inspection process and ensures the accuracy of the inspection results. The crystal rod 303 is installed within the precision air-floating plate 302. Its upper and lower surfaces are precisely aligned with the air-floating plate, achieving high flatness and excellent transparency. Through the crystal rod 303, the line scan camera 304 can directly see through the back of the flexible screen, capturing image information of the inspection area and thus detecting defects on the back of the flexible screen. The first line light source 305, mounted beneath the precision air-floating plate 302, provides uniform and bright illumination for the inspection area, ensuring that the line scan camera 304 captures clear and accurate image information. Furthermore, the camera adjustment mechanism 306 enhances the flexibility and adaptability of the inspection equipment. Through precise angle and position adjustments, the line scan camera 304 can easily adapt to inspection requirements of various shapes and locations, ensuring optimal results for each inspection.

[0046] In a specific embodiment, see Figure 3 The alignment component 4 includes an alignment camera 401, a fine-tuning slide 402 and a mounting bracket 403. The mounting bracket 403 is mounted on the shockproof frame 1, the fine-tuning slide 402 is mounted on the mounting bracket 403, and the alignment camera 401 is mounted on the fine-tuning slide 402. The fine-tuning slide 402 can drive the alignment camera 401 to move and adjust in three directions of the XYZ axis.

[0047] The alignment component 4 achieves precise capture and adjustment of product positioning points through the coordinated collaboration of the alignment camera 401, the fine-tuning slide 402, and the mounting bracket 403. Specifically, the alignment camera 401 is used to capture images of product positioning points, providing a reliable basis for subsequent positioning analysis. The fine-tuning slide 402, on the other hand, enables precise adjustment in three axes: X, Y, and Z. Adjusting the camera in the X and Y directions ensures that the product positioning point is centered in the alignment camera 401's field of view, while adjusting the camera focus in the Z direction ensures a clear image, thereby improving inspection accuracy and ensuring product quality.

[0048] In a specific embodiment, see Figure 4 and Figure 5The detection component 5 includes a detection camera 501, a fine-tuning mechanism 502, a mounting beam 503, a second line light source 504 and a light source bracket 505. The mounting beam 503 and the light source bracket 505 are both installed on the shockproof frame 1. The fine-tuning mechanism 502 is installed on the mounting beam 503. The detection camera 501 is installed on the fine-tuning mechanism 502. The fine-tuning mechanism 502 can realize the pitch, yaw and torsion adjustment of the detection camera 501. The light source bracket 505 is located below the mounting beam 503, and the second line light source 504 is installed on the light source bracket 505.

[0049] The detection component 5 achieves efficient and accurate detection of the target product through the coordinated cooperation of the detection camera 501, the fine-tuning mechanism 502, the mounting beam 503, the second line light source 504, and the light source bracket 505. Specifically, the detection camera 501 is responsible for capturing image information of the target product and providing data support for subsequent analysis and processing. The fine-tuning mechanism 502 has pitch, yaw, and torsion adjustment functions to ensure that the detection camera 501 can be aligned with the target product at the optimal angle and position, thereby improving the accuracy and stability of the detection. The second line light source 504 can provide uniform and bright lighting conditions for the target product, reducing problems such as uneven lighting or shadow interference, ensuring that the detection camera 501 can capture clear and accurate image information, and improving the accuracy and reliability of the detection.

[0050] In a specific embodiment, see Figure 6 The re-inspection component 6 includes a re-inspection camera 601, a second linear motor 602 and a support beam 603. The support beam 603 is installed on the shockproof frame 1, the second linear motor 602 is installed on the support beam 603, and the re-inspection camera 601 is installed on the mover seat of the second linear motor 602.

[0051] The re-inspection component 6 achieves secondary inspection and confirmation of the product through the coordinated cooperation of the re-inspection camera 601, the second linear motor 602, and the support crossbeam 603. Specifically, the re-inspection camera 601 is used to re-photograph the defects discovered by scanning, re-inspect them, and further confirm the product's quality status, reducing misjudgments or missed detections due to oversights in the initial inspection. This dual detection mechanism greatly improves the accuracy and reliability of the inspection. The second linear motor 602 realizes the automated movement and positioning of the re-inspection camera 601, which not only improves inspection efficiency but also reduces reliance on and errors caused by manual operation, thereby enhancing the automation and intelligence level of the inspection process.

[0052] In a specific embodiment, see Figure 6 A Z-axis slide 604 is also provided on the mover seat of the second linear motor 602 , and the re-inspection camera 601 is installed on the Z-axis slide 604 .

[0053] By installing a Z-axis slide 604, the inspection camera 601 can be moved up and down, enabling automatic focus when taking pictures, thereby improving the clarity and focus accuracy of the pictures. This optimization not only ensures image quality, but also further enhances the sensitivity and accuracy of defect detection, providing more refined technical support for product quality control.

[0054] In a specific embodiment, see Figure 2 The shock-proof frame 1 includes a mounting platform 101, a shock absorber 102 and a support frame 103. The flexible screen fixing mechanism 2, the air floating plate and the back inspection camera assembly 3, the alignment assembly 4, the detection assembly 5 and the re-inspection assembly 6 are all installed on the mounting platform 101. The upper and lower ends of the shock absorber 102 are respectively connected to the mounting platform 101 and the support frame 103.

[0055] The shockproof frame 1 forms a stable structure with good shock absorption performance through the cooperation of the mounting platform 101, the shock absorber 102 and the support frame 103. This design effectively reduces the interference of external vibration on the precision testing equipment, ensuring the smooth progress of the testing process and the accuracy of the test results.
