Abstract
Description
Technical Field
[0001] This invention relates to the field of visual inspection technology, and in particular to an intelligent visual inspection device and method based on the processing of conductive film on a keyboard. Background Technology
[0002] Membrane keyboards dominate the market due to their low cost, simple manufacturing process, and good tactile feel; most keyboards used in daily life are membrane keyboards. Examining the membrane circuit reveals that it consists of three layers: top, middle, and bottom. The top and bottom layers are control circuit layers, i.e., conductive films, where circuits are printed using conductive coating, and corresponding contacts are located below each key. The middle layer is the insulating layer, the keyboard membrane, which also has circular contacts (or perforated holes) on the keys. When a keycap is pressed, the circuits of the top and bottom layers are connected, generating a corresponding signal.
[0003] Referring to the patent application with publication number CN218411259U, an automated visual inspection device for conductive film of keyboard is disclosed. The automated visual inspection device for conductive film of keyboard includes a moving device, a visual inspection arm and an inspection platform. The visual inspection arm is mounted on the surface of the moving device, and the inspection platform is slidably mounted on the surface of the moving device. A lifting device for controlling the height of the visual inspection arm is installed inside the moving processing table. A pressure plate mechanism for pressing the conductive film is symmetrically fixedly connected to the surface of the inspection platform. An assembly mechanism for fixing is symmetrically fixedly connected to the surface of the pressure plate mechanism, and the visual inspection arm and the assembly mechanism are fixedly connected.
[0004] The following problems exist during use: The conductive film on the disc requires visual inspection of its surface quality and circuit patterns during production to ensure product qualification rate. Currently, most common inspection devices use a single inspection camera for image acquisition and analysis. However, in actual production, after prolonged use, the lens surface of the inspection camera easily accumulates dust or stains, leading to blurred images, false detections, or missed detections. Cleaning the camera usually requires stopping the machine for manual wiping, which not only affects inspection efficiency but may also damage the lens due to improper handling. Furthermore, existing devices lack camera self-testing and calibration functions, making it difficult to determine the camera's normal operating condition in real time, often requiring external calibration plates, increasing equipment complexity and maintenance costs.
[0005] Therefore, it is necessary to provide an intelligent visual inspection device and method based on keyboard conductive film processing to solve the above-mentioned technical problems. Summary of the Invention

[0016] The intelligent visual inspection method based on keyboard conductive film processing includes the following steps: Step 1: Place the keyboard conductive film on top of the moving platform and convey it into the upper cover frame; Step 2: During the conveying process, the electric push rod drives the moving frame to the top of the moving platform, and the smoothing mechanism smooths the conductive film of the keyboard. Step 3: Then, the conductive film of the keyboard is inspected by one of the inspection cameras.

[0020] 4. By setting an external motor, the motor's output shaft drives the drive gear to rotate, the drive gear drives the transmission gear ring to rotate, and the transmission gear ring drives the cleaning frame to rotate, causing the cleaning head to rotate and extend its cleaning outwards from the detection camera, thereby achieving full coverage of the camera lens, avoiding leaving any cleaning dead corners, and achieving a comprehensive cleaning effect.
[0021] 5. A micro motor is installed on the outside of the second take-up reel.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0026] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.
[0027] like Figures 1 to 10 As shown, the intelligent visual inspection device and method based on keyboard conductive film processing includes the following embodiments: Example 1: Includes a testing platform 1, with an upper cover frame 101 fixedly connected to the top of the testing platform 1. A diffuser plate 103 is fixedly connected inside the upper cover frame 101 for diffused light. A first sliding rail 102 for conveying is provided on the top of the testing platform 1. Also includes: The movable stage 2 is fixedly connected to the movable end of the first sliding rail 102. Two electric push rods 401 are fixedly connected to one side of the movable stage 2. The telescopic ends of the two electric push rods 401 are fixedly connected to the fixed plates 400. The movable frames 4 are fixedly connected to the outside of the fixed plates 400. The two movable frames 4 are set on the top of the movable stage 2 and are symmetrically arranged. The outside of the two movable frames 4 are provided with a smoothing mechanism for smoothing the conductive film. The second sliding rail 3 is fixedly connected inside the upper cover frame 101. A moving frame 301 is fixedly connected to the outer side of the moving end of the second sliding rail 3. Two sliding plates 302 are fixedly connected to the outer side of the moving frame 301. A detection camera 303 for detection is fixedly connected to the outer side of each of the two sliding plates 302. A first rack 304 is fixedly connected to the outer side of each sliding plate 302. A processing frame 8 is fixedly connected to both sides inside the first sliding rail 102. A cleaning mechanism for cleaning the detection camera 303 is provided inside the processing frame 8.
[0028] In practice, the keyboard conductive film is placed on top of the moving stage 2 and transported to the upper cover frame 101 via the first sliding rail 102. During transport, the moving frame 4 is moved to the top of the moving stage 2 by the electric push rod 401, and the keyboard conductive film is smoothed by a smoothing mechanism. Then, the keyboard conductive film is inspected by one of the detection cameras 303. After each inspection, the sliding plate 302 is moved by the second sliding rail 3, causing one of the detection cameras 303 to move into the processing frame 8 for cleaning, while the other detection camera 303 inspects the keyboard conductive film, thus achieving dual inspection and avoiding the impact of errors from a single detection camera 303 on the inspection results.
[0029] Example 2: The smoothing mechanism includes a lower pressure plate 402. Multiple first telescopic rods 403 and multiple first springs 4031 are fixedly connected between the lower pressure plate 402 and the movable frame 4. The multiple first springs 4031 are sleeved on the outside of the first telescopic rods 403. A first electromagnet is fixedly connected to the top of the movable frame 4. A first magnet 404 is fixedly connected to the top of the lower pressure plate 402. When the first electromagnet is energized, it repels the first magnet 404 magnetically.
[0030] The smoothing mechanism also includes a connecting plate 501, which is slidably disposed inside the movable frame 4. A dust blowing pipe 603 is fixedly connected to the bottom of the connecting plate 501. A first take-up roller 503 is rotatably connected to one end of the movable frame 4. A baffle 502 is wrapped and fixedly fixed to the outside of the first take-up roller 503. The baffle 502 is fixedly connected to the connecting plate 501. A second take-up roller 504 is rotatably connected to the other end of the movable frame 4. The second take-up roller 504 is connected to the movable frame 4 by a torsion spring. A self-inspection cloth 505 is wrapped and fixedly fixed to the outside of the second take-up roller 504. One end of the self-inspection cloth 505 is fixedly connected to the connecting plate 501.
[0031] In practice, when the conductive film needs to be smoothed, the electric push rod 401 moves the moving frame 4 to the top of the moving platform 2, so that one end of the two moving frames 4 contacts each other. Then, the first electromagnet at the top of the moving frame 4 is activated, and the first magnet 404 is pushed down by magnetic repulsion. The bottom of the pressure plate 402 contacts the conductive film and presses it down to ensure stability. The beneficial effect of this is to avoid film displacement and ensure accurate subsequent detection position. Then, by setting an external motor, the output shaft of the external motor is fixedly connected to the first winding roller 503. The rotation of the first winding roller 503 drives the baffle 502 to wind up. At this time, the baffle 502 pulls the connecting plate 501, and the connecting plate 501 drives the bottom dust blowing pipe 603 to move together, so that the dust blowing pipe 603 blows air onto the conductive film, blowing the dust and wrinkles on the surface of the conductive film outward. The air blowing and the baffle are linked, which efficiently removes dust and wrinkles and avoids secondary dust re-entrainment. Meanwhile, a self-inspection cloth 505 is provided between the connecting plate 501 and the second winding roller 504. The self-inspection cloth 505 unfolds accordingly, which can prevent dust from flying. (The unfolded self-inspection cloth forms a partially enclosed space, further suppressing dust.) Furthermore, after the self-inspection cloth 505 is unfolded, the detection camera 303 can perform self-inspection through the self-inspection cloth 505. The self-inspection cloth also serves as a standard reference, facilitating camera clarity detection and calibration without the need for additional calibration plates. Throughout the process, pressing, air blowing, cloth winding, and self-inspection cloth unfolding are all coordinated by the same drive chain, exhibiting strong action linkage, high automation, and reduced control complexity.
[0032] In this embodiment, an adsorption roller 601 is rotatably connected to the bottom of the connecting plate 501, and friction wheels 602 are fixedly connected to both ends of the adsorption roller 601. A friction pad is fixedly connected to the bottom of the moving frame 4. The friction wheel 602 contacts the friction pad and generates static electricity to attract dust through friction. A dust collection frame 604 for dust collection is fixedly connected to one end of the moving frame 4.
[0033] In practice, during the dust blowing process, an adsorption roller 601 is installed at the bottom of the connecting plate 501. When the adsorption roller 601 moves, the friction wheels 602, which are fixedly connected to both ends of the adsorption roller 601, come into contact with the friction pad at the bottom of the moving frame 4, causing the outer side of the adsorption roller 601 to acquire static electricity. The static electricity generated by friction can actively adsorb the flying dust, preventing the dust from escaping into the surrounding environment and improving the dust removal effect. During the dust blowing process, some dust can be adsorbed on the outer side of the adsorption roller 601, thereby reducing secondary pollution. The adsorption roller and the dust blowing pipe work together to ensure that the blown dust is promptly adsorbed by static electricity, preventing it from falling back onto the conductive film surface. Meanwhile, when the adsorption roller 601 moves to one end of the moving frame 4, the dust collection frame 604 is connected to the external dust collection pipe. The dust collection frame 604 continuously adsorbs dust and works in conjunction with the adsorption roller 601 and the dust blowing pipe 603 to complete multiple dust removal processes. The dust collection frame, adsorption roller, and dust blowing pipe work together to achieve efficient and thorough dust removal by utilizing the three principles of blowing, electrostatic adsorption, and negative pressure suction, respectively, thus ensuring the cleanliness of the conductive film surface.
[0034] Example 3: The cleaning mechanism includes a support plate 800, which is fixedly connected to the inside of the processing frame 8. A cleaning frame 9 is rotatably connected to the top of the support plate 800. The top of the cleaning frame 9 has multiple sliding grooves. Multiple connecting blocks 902 are provided inside the cleaning frame 9. Multiple electric telescopic rods 901 are fixedly connected to the outside of the cleaning frame 9. The telescopic ends of the multiple electric telescopic rods 901 pass through the outside of the cleaning frame 9 and are fixedly connected to the connecting blocks 902. A cleaning rod 903 is provided inside the connecting block 902. The cleaning rod 903 passes through the connecting block 902 and is movably connected to the connecting block 902. A cleaning head 904 is fixedly connected to the top of the cleaning rod 903. A second magnet 909 is fixedly connected to the bottom of the cleaning rod 903. A second electromagnet is fixedly connected to the bottom of the inside of the cleaning frame 9. The second electromagnet and the second magnet 909 are magnetically repelled.
[0035] The cleaning mechanism also includes a gear ring 911, which is rotatably connected to a connecting block 902. A protrusion is fixedly connected inside the connecting block 902. A groove 910 is provided on the outer side of the cleaning rod 903, and the protrusion extends into the groove 910. A toothed plate 900 is fixedly connected inside the cleaning frame 9, and the toothed plate 900 meshes with the gear ring 911. A transmission gear ring 912 is fixedly connected to the outer side of the cleaning frame 9, and a drive gear 913 meshes with the drive gear ring 912. The drive gear 913 is rotatably connected to the top of the support plate 800.
[0036] In practice, when the detection camera 303 to be cleaned moves into the processing frame 8, it is positioned directly above the cleaning frame 9. Activating the second electromagnet at the bottom of the cleaning frame 9 generates magnetic repulsion, which in turn pushes multiple second magnets 909 upwards. These magnets then push the cleaning head 904 at the top of the cleaning rod 903 into contact with the detection camera 303, achieving non-contact thrust control and preventing damage to the lens from hard impacts. Activating the electric telescopic rod 901 moves the connecting block 902, while the gear ring 911 meshes with the gear plate 900. The protrusions inside the gear ring 911 drive the cleaning rod 903 to rotate, significantly improving the cleaning effect of the cleaning head 904 and resulting in more even and thorough cleaning. In addition, a transmission gear ring 912 is fixedly connected to the outside of the cleaning frame 9. By setting an external motor, the output shaft of the motor drives the drive gear 913 to rotate, the drive gear 913 drives the transmission gear ring 912 to rotate, and the transmission gear ring 912 drives the cleaning frame 9 to rotate, so that the cleaning head 904 rotates and extends to the outside of the detection camera 303 for cleaning, thereby achieving full coverage of the camera lens, avoiding leaving cleaning dead corners, and achieving the effect of comprehensive cleaning.
[0037] In this embodiment: Limiting plates 905 are fixedly connected to both sides of multiple connecting blocks 902. A cleaning belt 906 is provided on the outside of the cleaning head 904. The cleaning belt 906 passes through the two limiting plates 905 and extends to the top of the cleaning head 904. A first take-up reel 907 and a second take-up reel 908 are rotatably connected to the outside of the cleaning frame 9. The two ends of the cleaning belt 906 are fixedly connected to the first take-up reel 907 and the second take-up reel 908 respectively.
[0038] In practice, when the cleaning head 904 cleans the detection camera 303, if it continues to clean for an extended period, it will inevitably accumulate dust, causing secondary contamination of the detection camera 303 during subsequent cleaning. Therefore, in this solution, the cleaning belt 906 passes through the limiting plate 905, allowing the cleaning head 904 to push the cleaning belt 906 into contact with the detection camera 303. This method avoids direct contact between the cleaning head 904 and the lens, preventing dust transfer. Furthermore, a micro motor is installed on the outside of the second take-up reel 908. The output shaft of the micro motor drives the second take-up reel 908 to rotate, ensuring the cleaning belt 906 remains clean and guaranteeing the use of a clean belt surface for each cleaning, thus preventing secondary contamination.
[0039] In this embodiment: a jet frame 10 is rotatably connected to the outside of the cleaning frame 9. The top of the jet frame 10 is provided with multiple nozzles and connected to an external air supply pipe. A dust suction hood 11 is fixedly connected inside the processing frame 8 and is connected to an external air suction pipe.
[0040] In practice, when the cleaning head 904 on the cleaning frame 9 is cleaning, air is sprayed into the air jet frame 10 through the external air supply pipe, so that the airflow pre-cleans the detection camera 303, and the dust is adsorbed and collected by the dust suction hood 11 to avoid dust being stirred up and causing pollution.
[0041] Example 4: A sealing plate 801 for sealing is provided on one side of the processing frame 8. A fixing rod 802 is fixedly connected to the top of the processing frame 8. A connecting plate 803 is fixedly connected to the outside of the sealing plate 801. The connecting plate 803 is slidably disposed outside the fixing rod 802. A second spring 804 is sleeved on the outside of the fixing rod 802. Both ends of the fixing rod 802 are fixedly connected to one end of the connecting plate 803 and the second spring 804, respectively. A rotating shaft 805 is provided inside the processing frame 8. The rotating shaft 805 passes through the processing frame 8 and is rotatably connected to the processing frame 8. A transmission gear 806 is fixedly connected to the top of the rotating shaft 805. The transmission gear 806 is meshed with the first rack 304. A traction rope is fixedly connected between the rotating shaft 805 and the sealing plate 801. When the rotating shaft 805 rotates, the sealing plate 801 is pulled by the traction rope to close the processing frame 8.
[0042] In practice, when the detection camera 303 moves into the processing frame 8 for cleaning, in order to ensure that dust does not overflow during the cleaning process, the first rack 304 on the outer side of the sliding plate 302 drives the transmission gear 806 to rotate. The transmission gear 806 drives the rotating shaft 805 to rotate. The rotating shaft 805 pulls the sealing plate 801 through the traction rope, so that the sealing plate 801 seals the processing frame 8, thereby forming a closed cleaning space and effectively preventing dust from leaking out and polluting the equipment or environment.
[0043] The intelligent visual inspection method based on keyboard conductive film processing includes the following steps: Step 1: Place the keyboard conductive film on the top of the moving stage 2 and convey it into the upper cover frame 101; Step 2: During the conveying process, the electric push rod 401 drives the moving frame 4 to move to the top of the moving platform 2, and the smoothing mechanism smooths the conductive film of the keyboard. Step 3: Then, the conductive film of the keyboard is detected by one of the detection cameras 303. After each detection is completed, the sliding plate 302 is driven by the second sliding rail 3, so that one of the detection cameras 303 moves into the processing frame 8 for cleaning, while the other detection camera 303 detects the conductive film of the keyboard.
