Description

Technical Field

[0001] This invention relates to the technical field of quantum film detection, specifically to a visual inspection device for quantum film surfaces. Background Technology

[0002] Quantum film is a light conversion film specifically designed for display technology. Through a unique quantum effect, it can effectively convert the properties of light, thus gradually gaining widespread application in various fields. This film material not only plays an important role in improving the performance of display devices, but also demonstrates its unique value and potential in many high-tech fields such as optical sensing and photoelectric conversion, and is gradually becoming one of the indispensable key materials in the development of modern science and technology.

[0003] A high-precision visual inspection device for surface defects of quantum films described in the prior art includes a support frame and a backlight inspection light box. The backlight inspection light box is located on the top of the support frame and includes a bottom shell, a backlight plate, a positioning plate, a cover shell, and a blue light transmitting plate. The top of the backlight plate is provided with a number of LED beads arranged in a rectangular array. The positioning plate is provided with a number of lamp holes corresponding one-to-one with the LED beads. The cover shell is provided with a light transmission groove in the middle, and the blue light transmitting plate is placed on the light transmission groove.

[0004] While the aforementioned technology can transform glaring white light into soft blue light through a blue light-transmitting panel, allowing workers to quickly identify defects or scratches on the quantum film under blue light illumination without causing visual fatigue even during long-term working environments, the fixed position of the backlight detection light box prevents flexible adjustment according to the actual detection needs of the quantum film, resulting in a limited detection range. It also leads to poor detection results for some quantum films with special shapes or sizes. Furthermore, the device lacks effective measures to fix the quantum film during the detection process, making it prone to movement or shaking, thus affecting the accuracy and stability of the detection. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a quantum film surface visual inspection device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A quantum film surface visual inspection device includes an inspection platform, with support plates fixed on both sides of the lower surface of the inspection platform. An installation slot is formed on the inspection platform, and a transparent plate is installed in the installation slot. An inspection light box is located below the transparent plate.

[0007] Preferably, the moving component includes two rotating shafts, one end of each of the two rotating shafts being fixedly connected to the outer walls of both sides of the fixed block. Each side wall of the mounting box has a strip-shaped moving groove, and a slider is slidably installed in each of the two moving grooves. A fixing plate is installed on the side of each slider near the rotating shaft by screws. The other end of each of the two rotating shafts is rotatably connected to the fixing plate. Vertical plates are installed on the upper surface of each slider extending from the mounting box by screws. Strip-shaped sliding grooves are provided on both sides of the mounting grooves on the detection platform. A top plate is fixed to the top of each of the two vertical plates through the strip-shaped sliding grooves. Both cameras are installed on the lower surface of the top plate by screws.

[0008] Preferably, both outer walls of the mounting box are in contact with the corresponding support plate walls, both side walls of the two fixing plates are welded with side plates, and an electric telescopic cylinder is symmetrically installed on the outer wall of one of the support plates by screws. The telescopic ends of the two electric telescopic cylinders penetrate the support plate and the wall of the mounting box and are fixed to the corresponding side plates with screws.

[0009] Preferably, a strip-shaped side block is fixed to one side of the outer wall of the top plate, and a rod is movably inserted through the side block. Both ends of the side block are provided with connecting rods that are fixedly connected to the rods. A pressure roller is rotatably installed between the other ends of the two connecting rods, and a silicone sleeve is fitted over the pressure roller.

[0010] Preferably, both sides of the outer walls of the two sliders are connected to telescopic baffles by screws, each telescopic baffle is fixedly connected to the outer wall of the mounting box by screws, and the telescopic surface of each telescopic baffle is in contact with the outer wall of the mounting box.

[0011] Preferably, the adjustment assembly includes a drive motor and worm gears mounted on two rotating shafts. The lower tooth surfaces of the two worm gears are meshed with worms. The two ends of the two worms are rotatably connected to corresponding side plates. One end of each worm passes through the side plate and is fixed with a first magnetic plate. The inner side wall of the mounting box is provided with a second magnetic plate at the location of the two first magnetic plates.

[0012] Preferably, a protective shell is installed on the outer wall of the other support plate by screws, and two shafts are symmetrically inserted through the support plate. The ends of the two shafts are fixedly connected to the second magnetic plate, which is magnetically connected to the first magnetic plate. A transmission wheel is fixedly sleeved on the outer wall of the other end of the two shafts. The two transmission wheels are connected by a transmission chain. The output end of the drive motor is connected to a shaft through a coupling. The drive motor is installed on the inner wall of the protective shell by screws.

[0013] Preferably, the upper surface edge of the transparent plate is provided with an adsorption groove, and the bottom of the adsorption groove is provided with a plurality of adsorption holes evenly distributed.

[0015] Preferably, the negative pressure box is located at the inner edge of the mounting box.

[0016] In summary, the present invention has the following main advantages: by setting up moving and adjusting components, the light box can be moved flexibly and its angle adjusted. The moving component uses an electric telescopic cylinder to push the slider to slide on the moving track, which moves the light box and camera together, enabling comprehensive scanning of quantum films of different sizes and greatly enhancing adaptability. The adjusting component, through worm gear transmission and magnetic coupling linkage, can flexibly switch the light box from vertical illumination to 45° oblique illumination, accurately capturing even hidden defects of quantum films with special shapes. Furthermore, by creating adsorption grooves, adsorption holes, and a negative pressure box on the upper edge of the transparent plate, and using an air pump, the quantum membrane is effectively fixed. A pressure roller moves with the camera to flatten minute wrinkles and bubbles on the quantum membrane surface in real time, preventing false defects from interfering with the detection results. Simultaneously, an LED strip on the mounting plate inside the adsorption groove forms a ring-shaped auxiliary light source, complementing the blue light illumination from the detection light box. For minor scratches and burrs easily overlooked at the edges of the quantum membrane, the ring-shaped supplementary light enhances the contrast between the defects and the membrane, significantly improving the defect recognition rate in the edge areas and achieving full-surface, blind-angle-free detection.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of the present invention will now be described.

[0021] It should be noted that a main controller is added to the upper surface of the inspection platform 1. This controller is electrically connected to the electric telescopic cylinder 509, drive motor 604, air pump 204, camera 8, LED backlight panel 401 and LED lights on the mounting plate 202 via wires. It is used to uniformly receive instructions, coordinate the timing of the actions of each component, realize the automated control of the inspection process, and at the same time receive the image data collected by the camera 8 in real time and perform preliminary defect identification processing.

[0022] In this embodiment, please refer to Figures 1-6As shown, a quantum film surface visual inspection device includes an inspection platform 1. Support plates 101 are fixed on both sides of the lower surface of the inspection platform 1. An installation slot 102 is opened on the inspection platform 1. A transparent plate 2 is installed in the installation slot 102. An inspection light box 4 is provided below the transparent plate 2. An installation box 3 with a top opening is fixed to the lower surface of the inspection platform 1 by screws. An LED backlight plate 401 is installed in the bottom of the inspection light box 4. A blue light transmitting plate 402 is installed at the top opening of the inspection light box 4. A fixing block 403 is fixed to the lower surface of the inspection light box 4. Two cameras 8 are provided on one side above the transparent plate 2. An adsorption groove 201 is provided on the upper edge of the transparent plate 2. Several adsorption holes 2011 are evenly provided on the bottom of the adsorption groove 201. A matching negative pressure box 203 is installed on the lower surface of the transparent plate 2 at the adsorption groove 201. The negative pressure box 203 is located at the inner edge of the mounting box 3. An air pump 204 is installed on the top of the outer wall of a support plate 101 by screws. The suction port of the air pump 204 is connected to the negative pressure box 203 through a pipe. An mounting plate 202 is provided in the adsorption groove 201. The width of the mounting plate 202 is smaller than the width of the adsorption groove 201. Both outer walls of the mounting plate 202 are fixedly connected to the groove wall by a bracket plate. An LED light strip is glued to the upper surface of the mounting plate 202. Inside the mounting box 3, on both sides of the fixed block 403, there are moving components 5. The moving components 5 are used to drive the detection light box 4 and the two cameras 8 to move synchronously. An adjustment component 6 is installed on one inner wall of the mounting box 3. The adjustment component 6 cooperates with the moving components 5. The adjustment component 6 is used to control the detection light box 4 from vertical to 45° tilted oblique beam as needed after the moving components 5 push the detection light box 4 closer.

[0023] Before testing the quantum membrane, the operator first lays the quantum membrane to be tested flat on the upper surface of the transparent plate 2. Before laying it flat, the surface of the quantum membrane is wiped with a lint-free cloth to remove dust and grease. After laying it flat, ensure that the edge of the quantum membrane covers the area of ​​the adsorption tank 201 and that the membrane surface is not folded. At this time, the air pump 204 is started by the controller. The air pump 204 draws air from the inside of the negative pressure box 203 through the pipe, so that a stable negative pressure is formed in the negative pressure box 203. This negative pressure is transmitted to the edge of the quantum membrane through several adsorption holes 2011 at the bottom of the adsorption tank 201, firmly adsorbing the quantum membrane onto the surface of the transparent plate 2, preventing the membrane from moving or shaking during the test. At the same time, the controller can start the LED light strip on the mounting plate 202 according to the test requirements. The light emitted by the LED light strip forms a ring auxiliary light source along the adsorption tank 201, providing supplementary lighting for the edge area of ​​the quantum membrane and avoiding blind spots in edge detection. At this time, the LED backlight panel 401 inside the detection light box 4 continuously emits light. After being filtered by the blue light transmittance panel 402, the light is converted into soft blue light, which penetrates the transparent panel 2 and illuminates the lower surface of the quantum film. After the quantum film is fixed, when it is vertically irradiated (initial state), the moving component 5 is started by the controller to perform the detection operation, so that the detection light box 4 and the two cameras 8 move along the length of the transparent panel 2. During the movement, the pressure roller 508 will first contact the upper surface of the quantum film and roll it to flatten any tiny wrinkles or bubbles that may exist on the surface of the quantum film in real time, ensuring that the film always remains flat and avoiding false defects from affecting the detection accuracy. The vertically irradiated blue light penetrates the quantum film vertically, making it easy to identify light transmittance defects such as pinholes and impurities. When it is necessary to adjust the detection light box 4 (i.e., to perform 45° oblique illumination), the controller starts the adjustment component 6 before starting the moving component 5 to adjust the illumination angle of the detection light box 4. With 45° oblique illumination, the light forms obvious light and shadow contrast at the scratches and indentations on the quantum film surface, which is convenient for capturing subtle surface concave and convex defects. During the irradiation of the quantum film, two cameras 8, which move synchronously with the detection light box 4, capture the reflected images of the upper surface of the quantum film in real time. The image data is transmitted to the controller in real time. The controller performs grayscale processing, defect contour extraction and other analyses on the images to complete the automatic identification and recording of defects. This enables the flexible movement and angle adjustment of the light box, which can comprehensively scan quantum films of different sizes, greatly enhancing its adaptability. The light box can also be flexibly switched from vertical irradiation to 45° oblique irradiation, and even hidden defects of quantum films with special shapes can be accurately captured.

[0024] Please see Figures 5-7 As shown, the moving component 5 includes two rotating shafts 501. One end of each rotating shaft 501 is fixedly connected to the outer walls of both sides of the fixed block 403. Each side wall of the mounting box 3 has a strip-shaped moving groove 301. A slider 504 is slidably installed in each of the two moving grooves 301. A fixing plate 502 is mounted on the side of each slider 504 near the rotating shaft 501 using screws. The other end of each rotating shaft 501 is rotatably connected to the fixing plate 502. Vertical plates 505 are mounted on each slider 504 extending out of the upper surface of the mounting box 3 using screws. The detection platform 1 is located on the mounting groove 1. 02 Both sides are provided with strip grooves 103. The top of the two vertical plates 505 are fixed to the top plate 5051 through the strip grooves 103. The two cameras 8 are installed on the lower surface of the top plate 5051 by screws. The outer walls of both sides of the mounting box 3 are in contact with the walls of the corresponding support plates 101. The two side walls of the two fixing plates 502 are welded with side plates 503. The outer wall of one support plate 101 is symmetrically installed with electric telescopic cylinders 509 by screws. The telescopic ends of the two electric telescopic cylinders 509 are fixed to the corresponding side plates 503 by screws through the support plate 101 and the wall of the mounting box 3. A strip-shaped side block 506 is fixed to one side outer wall of the top plate 5051. A rod is movably inserted through the side block 506. Both ends of the side block 506 are provided with connecting rods 507 that are fixedly connected to the rods. A pressure roller 508 is rotatably installed between the other ends of the two connecting rods 507. A silicone sleeve is fitted on the outside of the pressure roller 508. Both sides of the outer walls of the two sliders 504 are connected with telescopic baffles 302 by screws. Each telescopic baffle 302 is fixedly connected to the outer wall of the mounting box 3 by screws. The telescopic surface of each telescopic baffle 302 is in contact with the outer wall of the mounting box 3.

[0025] When the detection light box 4 is moved, the controller sends extension and retraction commands to the two electric telescopic cylinders 509. The extension and retraction ends of the electric telescopic cylinders 509 synchronously push the connected side plate 503. The side plate 503 drives the fixed plate 502 and the slider 504 to move. The slider 504 slides smoothly along the moving slots 301 on both sides of the mounting box 3, and drives the top plate 5051 to move synchronously through the vertical plate 505. The fixed plate 502 drives the rotating shaft 501 to move, and drives the connected fixed block 403 to move through the rotating shaft 501. Therefore, when the slider 504 moves, it will synchronously drive the detection light box 4 and the two cameras 8 to move along the length direction of the transparent plate 2. When the slider 504 moves, the telescopic baffles 302 on both sides of the slider 504 will extend and retract synchronously, always tightly fitting the outer wall of the mounting box 3, sealing the moving slots 301, and preventing dust in the environment from entering the mounting box 3 and contaminating the LED backlight plate 401, blue light transmitting plate 402 and other optical components. During the movement, the top plate 5051 will also drive the side block 506 and the pressure roller 508 connected by the connecting rod 507 to move. The pressure roller 508 keeps in contact with the upper surface of the detection platform 1 under its own gravity. As the top plate 5051 moves, the pressure roller 508 rolls along the surface of the quantum membrane. The silicone sleeve on its outside flattens any tiny wrinkles and bubbles that may exist on the surface of the quantum membrane in real time without damaging the membrane, ensuring that the membrane always remains flat and avoiding false defects from affecting the detection accuracy.

[0026] Please see Figure 5 , Figure 7 and Figure 8As shown, the adjustment assembly 6 includes a drive motor 604 and worm gears 601 mounted on two rotating shafts 501. Worms 602 are meshed with the lower tooth surfaces of the two worm gears 601. The two ends of the two worms 602 are rotatably connected to corresponding side plates 503. One end of each worm 602 passes through the side plate 503 and is fixed with a first magnetic plate 603. A second magnetic plate 607 is provided on the inner wall of the mounting box 3 at the locations of the two first magnetic plates 603. A protective cover is installed on the outer wall of the other support plate 101 by screws. The shell 7 has two shafts 605 symmetrically inserted through the support plate 101. The ends of the two shafts 605 are fixedly connected to the second magnetic plate 607. The second magnetic plate 607 is magnetically connected to the first magnetic plate 603. The outer walls of the other ends of the two shafts 605 are fixedly fitted with transmission wheels 606. The two transmission wheels 606 are connected by a transmission chain 6061. The output end of the drive motor 604 is connected to one of the shafts 605 through a coupling. The drive motor 604 is mounted on the inner wall of the protective shell 7 by screws.

[0027] When the detection light box 4 needs to be adjusted from vertical to a 45-degree angled beam, in the initial state, the second magnetic plate 607 on the side of the detection light box 4 closest to the mounting box 3 is attracted to the first magnetic plate 603 on the rotating shaft 501 due to magnetic attraction, thus achieving coupling of power transmission. At this time, the controller starts the drive motor 604. The output end of the drive motor 604 drives a shaft 605 to rotate through a coupling. This shaft 605 drives another shaft 605 to rotate synchronously through the transmission wheel 606 and the transmission chain 6061. The two shafts 605 respectively drive the corresponding second magnetic plate 607, first magnetic plate 603 and worm gear 602 to rotate. The rotation of the worm gear 602 The motion is converted into the circumferential rotation of the worm gear 601, which in turn drives the rotating shaft 501 to rotate around the fixed plate 502 and the fixed block 403 to rotate, realizing the switching of the detection light box 4 from the vertical illumination state to the 45° tilted illumination state. After the switch, the moving component 5 moves the detection light box 4 tilted at 45°. At this time, the fixed plate 502 drives the worm gear 602 to move synchronously through the side plate 503, so that the first magnetic plate 603 and the second magnetic plate 607 are separated. The worm gear 602 always maintains a meshing state with the worm gear 601 during the movement. This design ensures that the detection light box 4 remains unchanged at the angle after the angle is adjusted due to its self-locking property.

[0028] The working principle of this invention is as follows: Before testing the quantum membrane, the operator first lays the quantum membrane to be tested flat on the upper surface of the transparent plate 2. Before laying it flat, the surface of the quantum membrane is wiped with a lint-free cloth to remove dust and grease. After laying it flat, ensure that the edge of the quantum membrane covers the area of ​​the adsorption tank 201 and that the membrane surface is not folded. At this time, the air pump 204 is started by the controller. The air pump 204 draws air from the inside of the negative pressure box 203 through the pipe, so that a stable negative pressure is formed in the negative pressure box 203. This negative pressure is transmitted to the edge of the quantum membrane through several adsorption holes 2011 at the bottom of the adsorption tank 201, firmly adsorbing the quantum membrane onto the surface of the transparent plate 2, preventing the membrane from moving or shaking during the test. At the same time, the controller can start the LED light strip on the mounting plate 202 according to the test requirements. The light emitted by the LED light strip forms a ring auxiliary light source along the adsorption tank 201, providing supplementary lighting for the edge area of ​​the quantum membrane and avoiding blind spots in edge detection. At this time, the LED backlight panel 401 inside the detection light box 4 continuously emits light. After being filtered by the blue light-transmitting plate 402, the light is converted into soft blue light, which penetrates the transparent plate 2 and illuminates the lower surface of the quantum film. After the quantum film is fixed, when vertically irradiated (initial state), the controller sends a telescopic command to the two electric telescopic cylinders 509. The telescopic ends of the electric telescopic cylinders 509 synchronously push the connected side plate 503. The side plate 503 drives the fixed plate 502 and the slider 504 to move. The slider 504 slides smoothly along the moving slots 301 on both sides of the mounting box 3, and is carried by the vertical plate 505. The moving top plate 5051 moves synchronously, while the fixed plate 502 drives the rotating shaft 501 to move. The rotating shaft 501 drives the connected fixed block 403 to move. Therefore, when the slider 504 moves, it will synchronously drive the detection light box 4 and the two cameras 8 to move along the length of the transparent plate 2. When the slider 504 moves, the telescopic baffles 302 on both sides of the slider 504 will extend and retract synchronously, always tightly fitting the outer wall of the mounting box 3, sealing the moving channel 301, and preventing dust in the environment from entering the mounting box 3 and contaminating the LED backlight plate 401, blue light transmitting plate 402 and other optical components. During the movement, the top plate 5051 will also drive the side block 506 on one side and the pressure roller 508 connected by the connecting rod 507 to move. The pressure roller 508 maintains contact with the upper surface of the detection platform 1 under its own gravity. As the top plate 5051 moves, the pressure roller 508 rolls along the surface of the quantum membrane. The silicone sleeve on its outside flattens out any tiny wrinkles or bubbles that may exist on the surface of the quantum membrane in real time without damaging the membrane. When the detection light box 4 needs to be adjusted (i.e., to be illuminated at a 45° angle), the controller starts the drive motor 604 of the adjustment component 6 before starting the moving component 5. The output end of the drive motor 604 drives a shaft 605 to rotate through a coupling. This shaft 605 drives another shaft 605 to rotate synchronously through the transmission wheel 606 and the transmission chain 6061. The two shafts 605 respectively drive the corresponding second magnetic plate 607, first magnetic plate 603 and worm gear 602 to rotate. The rotational motion of the worm gear 602 is converted into the circumferential rotation of the worm wheel 601, which in turn drives the rotating shaft 501 to rotate around the fixed... The fixed plate 502 rotates, which in turn drives the fixed block 403 to rotate, thereby switching the detection light box 4 from a vertical illumination state to a 45° tilted illumination state. After the switch, the moving component 5 moves the detection light box 4 tilted at 45°. At this time, the fixed plate 502 drives the worm gear 602 to move synchronously through the side plate 503, so that the first magnetic plate 603 and the second magnetic plate 607 are separated. The worm gear 602 always maintains a meshing state with the worm wheel 601 during the movement. This design ensures that the detection light box 4 remains at the same angle after the angle is adjusted due to its self-locking property. During the irradiation of the quantum film, two cameras 8, which move synchronously with the detection light box 4, capture the reflected images of the upper surface of the quantum film in real time. The image data is transmitted to the controller in real time. The controller performs grayscale processing, defect contour extraction and other analyses on the images to complete the automatic identification and recording of defects.
