Description

Technical Field

[0001] This invention relates to the field of camera inspection, specifically to an invention of a device for inspecting the appearance of new energy camera production. Background Technology

[0002] As a core sensor for autonomous driving systems and environmental perception, the demand for and quality requirements of automotive cameras are growing exponentially. During the camera production process, after assembly, a rigorous visual inspection must be carried out. The core items of the visual inspection include: whether the sealing ring (such as O-ring) at the connection between the lens and the housing is missing, deformed, or poorly assembled; the cleanliness of the lens surface (free from dust, fingerprints, and oil); and whether the lens retaining ring or buckle is properly assembled. Traditional inspection methods mainly rely on manual visual inspection, which is inefficient, subjective, and prone to fatigue and missed inspections. It can no longer meet the requirements of modern production lines for high cycle time and high consistency. Therefore, machine vision automatic inspection devices have become the mainstream direction for industry upgrades. Existing automated vision inspection systems typically include industrial camera light sources and image processing units.

[0003] Currently used camera appearance inspection devices combine visual inspection equipment with image processing systems for inspection. However, this inspection process has the following obvious drawbacks: 1. The installation status of the sealing ring is not checked. Image transmission processing cannot accurately detect whether the sealing ring is installed in place or whether it fits the sealing groove completely.

[0004] 2. Lack of pre-inspection cleaning leads to a high misjudgment rate. Fine impurities can easily adhere to the surface of visual inspection devices and cameras, causing the image processing system to make misjudgments. Summary of the Invention

[0005] This invention provides a new energy camera production appearance inspection device to solve the problems of traditional camera visual inspection devices not having the ability to perform non-destructive testing of the sealing ring installation status and cleaning of the lens before inspection.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An invention provides an appearance inspection device for the production of new energy cameras, including an inspection table. The inspection device includes: a placement seat adapted to the size of the camera and disposed on the top of the inspection table; an inspection chamber sealed to the top of the placement seat; an inclined visual inspection device installed inside the inspection chamber; a pressurized air pipe disposed on the side wall of the inspection chamber; and a pressure monitoring module disposed on the top of the inspection chamber. The inspection device further includes a tracking inspection mechanism disposed inside the inspection chamber, the tracking inspection mechanism being used to drive the visual inspection device to perform cyclic inspection of the camera's sealing ring; and A cleaning mechanism installed on the side wall of the inspection chamber is used to clean impurities from the camera lens.

[0007] The beneficial effects of this invention are: This invention designs an automated, non-destructive visual inspection device for the installation status of sealing rings. Through the coordination of a placement base, inspection chamber, visual inspection device, pressurized air pipe, pressure monitoring module, tracking inspection mechanism, and cleaning mechanism, the visual inspection device, in conjunction with the pressure monitoring module, delivers rated air pressure into the inspection chamber. Using a non-contact pressure difference method, it can inspect the installation status and airtightness of the sealing ring at the camera lens, overcoming the limitation of existing visual inspection methods that cannot accurately identify the installation depth of the sealing ring, thus avoiding potential sealing failure. Simultaneously, the coordination of the tracking inspection mechanism and the visual inspection device allows adjustment of the visual inspection device's angle to inspect the edge of the camera lens. Furthermore, driving the visual inspection device to rotate enables tracking inspection of the camera lens edge. This dual inspection of pressure difference and visual inspection effectively and accurately checks the installation status of the sealing ring at the camera lens. Before inspection, the pressurized air pipe, in conjunction with the cleaning mechanism, uses a "gas supply + gas extraction" synergistic cleaning process. This not only removes impurities with high-pressure airflow but also quickly removes them, preventing impurities from remaining or entering lens gaps.

[0016] The present invention provides the following preferred embodiments: Example 1 refer to Figure 1 and Figure 4 As shown, a new energy camera production appearance inspection device includes an inspection table 1. The inspection device includes: a placement seat 2 adapted to the size of the camera and set on the top of the inspection table 1; an inspection chamber 3 is sealed and connected to the top of the placement seat 2; an inclined visual inspection device 4 is installed inside the inspection chamber 3; a pressurized air pipe 5 is set on the side wall of the inspection chamber 3; and a pressure monitoring module 6 is set on the top of the inspection chamber 3. The inspection device also includes a tracking inspection mechanism 7 disposed inside the inspection chamber 3, which drives the visual inspection device 4 to perform cyclic inspection of the camera's sealing ring; and The cleaning mechanism 8, which is installed on the side wall of the inspection chamber 3, is used to clean impurities from the camera lens.

[0017] The system comprises a testing platform 1, a placement seat 2, an inspection chamber 3, a visual inspection device 4, a pressurized air pipe 5, a pressure monitoring module 6, a tracking inspection mechanism 7, and a cleaning mechanism 8. The placement seat 2 is adapted to the size of the pre-installed camera, providing limiting and stable support for the camera. The inspection chamber 3, adapted to the camera, forms a sealed space between the inspection chamber 3 and the camera. The visual inspection device 4 connects to an external host system to detect and transmit image information from the camera. Before inspection, the pressurized air pipe 5 delivers clean airflow into the inspection chamber 3 to flush the visual inspection device 4 and the camera lens. The pressurized air pipe 5 and the cleaning mechanism 8 work together to clean the cleaned airflow from the pressurized air pipe 5 and the air floating in the inspection chamber 3. The internal gas and impurities are extracted, achieving a combination of blowing and sucking. During the inspection phase of the visual inspection device 4, airflow is delivered into the inspection chamber 3 through the pressurized air pipe 5, bringing the interior of the inspection chamber 3 to the rated air pressure. The pressure detection module detects the air pressure inside the inspection chamber 3, and the lack of air pressure is used to detect whether the camera sealing ring is installed in place. The tracking inspection mechanism 7 can adjust the angle of the visual inspection device 4 to inspect the edge of the camera lens. At the same time, the visual inspection device 4 is driven to rotate to achieve tracking inspection of the edge of the camera lens. Through the dual inspection of air pressure difference and visual inspection, the installation status of the sealing ring at the camera lens can be accurately inspected.

[0018] When using a new energy camera to produce an appearance inspection device, follow these steps: Cleaning stage: The camera to be tested is precisely placed on the placement seat 2 on the top of the testing table 1 (the placement seat 2 is compatible with the camera to ensure stable positioning). The inspection chamber 3 descends and fits against the top of the camera to form a relatively sealed space. Then, the pressurized air pipe 5 is controlled to deliver high-pressure airflow into the inspection chamber 3. At the same time, the cleaning structure starts to extract air. The high-pressure airflow blows the lens of the visual inspection device 4 and the lens of the camera, removing the attached dust, oil and other impurities. The cleaning mechanism 8 quickly extracts the impurities out of the inspection chamber 3. Through the coordinated operation of "air supply + air extraction", double cleaning is achieved.

[0019] Inspection Phase: After cleaning, the pressurization pipe supplies gas into the inspection chamber 3, bringing it to its rated pressure. The pressurization pipe 5 and cleaning mechanism 8 are then closed to seal the inspection chamber 3. The tracking inspection mechanism 7 moves the visual inspection device 4 to adjust its position for comprehensive visual imaging of the camera lens surface, capturing images of the lens appearance (identifying stains, scratches, and other defects). Simultaneously, the pressure monitoring module 6 monitors the pressure changes within the inspection chamber 3 in real time, using the pressure difference principle to determine the sealing ring installation status. If the sealing ring is properly installed, the inspection chamber 3 has good sealing, and the pressure remains stable. If the sealing ring is not properly installed, is offset, or is missing, air is present in the inspection chamber 3, causing the pressure to drop rapidly, thus accurately determining whether the sealing ring installation is qualified. Simultaneously, the tracking inspection mechanism 7 adjusts the visual inspection device 4, tilting it towards the sealing ring and rotating it to track and inspect all aspects of the sealing ring. Through this dual inspection of pressure difference and visual inspection, the installation status of the camera sealing ring, whether it is properly installed, and any sealing issues can be accurately determined.

[0020] In this embodiment, through the cooperation of the visual inspection group device, the pressurized air pipe 5, the pressure monitoring module 6, the tracking inspection mechanism 7, and the cleaning mechanism 8, the "air supply + air extraction" collaborative cleaning can not only remove impurities through high-pressure airflow, but also quickly remove impurities, preventing impurities from remaining or entering the lens gaps. At the same time, it can clean the lens of the visual inspection device 4 and the camera lens, preventing image acquisition distortion and solving the defect of poor effect of single cleaning methods. In addition, the visual inspection device 4, together with the air pressure detection module, can not only detect lens appearance defects, but also detect whether the sealing ring is installed in place through non-contact detection of air pressure difference, making up for the deficiency of existing visual inspection in accurately identifying the installation depth of the sealing ring and avoiding the risk of seal failure.

[0021] Example 2 refer to Figure 5 As shown, the tracking and inspection agency 7 includes: A tracking motor 71 is installed at the top of the inspection chamber 3. The output end of the tracking motor 71 is equipped with a mounting bracket 72. The bottom of the mounting bracket 72 is equipped with two vertical plates 73. The bottom of the two vertical plates 73 is hinged with a diagonal bar 74. The visual inspection device 4 is fixedly connected to the bottom of the diagonal bar 74. An adjusting electric push rod 75 is installed in the middle of the mounting bracket 72. The output end of the adjusting electric push rod 75 is hinged with an adjusting bar 76. The other end of the adjusting bar 76 is hinged to the diagonal bar 74. The output end of the adjusting electric push rod 75 is movably positioned between the two vertical plates 73.

[0022] By setting up a tracking motor 71, a mounting frame 72, a vertical plate 73, a diagonal bar 74, an adjusting electric push rod 75, and an adjusting bar 76, the mounting frame 72 is set on the top of the inspection chamber 3, providing an adjustment carrier for the visual inspection device 4. By adjusting the output of the electric push rod 75, the adjusting bar 76 is hinged to the diagonal bar 74. At the same time, the bottom of the mounting frame 72 is hinged to the two vertical plates 73, so that the lifting and lowering motion of the adjusting electric push rod 75 is converted into driving the diagonal bar 74 to rotate along its hinge point with the bottom of the vertical plate 73, thereby realizing the adjustment of the angle of the visual inspection device 4. Through the output of the servo motor, the mounting frame 72 can rotate, thereby enabling the visual inspection device 4 to rotate to perform a comprehensive inspection of the camera lens and the sealing ring connection.

[0023] In specific work: Horizontal rotation adjustment: The servo motor is fixed to the top of the inspection chamber 3, and its output end is fixedly connected to the mounting frame 72. Starting the servo motor can drive the mounting frame 72 to rotate horizontally around the axis of the servo motor, thereby driving the visual inspection device 4 on the mounting frame 72 to rotate synchronously, realizing the 360° full coverage adjustment of the visual inspection device 4 in the horizontal direction, which can adapt to the inspection requirements of the ring area of ​​the camera lens. Pitch angle adjustment: The output end of the electric adjustment push rod 75 in the middle of the mounting bracket 72 is hinged to the adjustment bar 76, the other end of the adjustment bar 76 is hinged to the inclined bar 74, and the bottom of the inclined bar 74 is hinged to the bottom of the two vertical plates 73, forming a multi-set hinge linkage structure; when it is necessary to adjust the pitch angle of the visual inspection device 4, the electric adjustment push rod 75 extends and retracts, pushing the adjustment bar 76 to drive the inclined bar 74 to rotate around its hinge point with the vertical plate 73, and the visual inspection device 4 at the bottom of the inclined bar 74 adjusts the pitch angle accordingly, which can accurately aim at different areas of the camera lens (such as the central area and the edge area) to achieve shooting without blind spots.

[0024] Example 3 refer to Figure 2 and Figure 6 As shown, the cleaning mechanism 8 includes: A cleaning pipe 81 is installed on the side wall of the inspection chamber 3. The cleaning pipe 81 and the pressurized air pipe 5 are symmetrically arranged. The pressurized air pipe 5 is connected to the air pump 82. The cleaning pipe 81 is connected to the vacuum cleaner 83. An adjustment assembly 84 is installed on the side wall of the inspection chamber 3. The adjustment assembly 84 is used to adjust the position of the cleaning pipe 81 and the pressurizing pipe 5 inside the inspection chamber 3.

[0025] By setting up a cleaning pipe 81, an air pump 82, a vacuum cleaner 83, and an adjustment component 84, before inspection, the air pump 82 delivers clean gas into the inspection chamber 3 through the pressurized air pipe 5 to blow and clean the camera lens inside the inspection chamber 3. At the same time, the vacuum cleaner 83 is activated to extract dust, impurities, etc. from inside the inspection chamber 3 through the cleaning pipe 81, thereby cleaning the inspection chamber 3.

[0026] In specific work: Air supply channel: The high-pressure airflow generated by the air pump 82 is delivered to the pressurized air pipe 5, and then introduced into the inspection chamber 3 through the pressurized air pipe 5 to provide airflow power for lens cleaning; Air extraction channel: The cleaning pipe 81 is connected to the vacuum cleaner 83. After the vacuum cleaner 83 is started, it generates negative pressure, which draws out the impurity airflow in the inspection chamber 3 through the cleaning pipe 81 to achieve impurity collection.

[0027] In this embodiment, the cleaning pipe 81, air pump 82, dust collection device 83 and adjustment component 84 work together to effectively supply and exhaust air into the inspection chamber 3, efficiently cleaning the camera lens inside the inspection chamber 3, and cleaning the dust adhering to the lens of the visual inspection device 4.

[0028] Example 4 refer to Figure 6 As shown, the adjustment component 84 includes: A base plate 841 is located at the bottom of the inspection chamber 3 and contacts the camera. A rotating ring 842 is mounted on the inner wall of the inspection chamber 3. The pressurized air pipe 5 and the cleaning pipe 81 are fixedly connected to the middle of the rotating ring 842. A movable groove 843 is provided on the side wall of the inspection chamber 3 and is movably connected to the pressurized air pipe 5 and the cleaning pipe 81. A driving component 844 for driving the rotating ring 842 to rotate is provided on the top of the base plate 841.

[0029] By setting up a base plate 841, a rotating ring 842, a movable groove 843, and a drive component 844, when the adjustment component 84 is working, the drive component is activated, and the drive component 844 drives the rotating ring 842 to rotate inside the inspection chamber 3. Since the pressurized air pipe 5 and the cleaning pipe 81 are both fixedly connected to the rotating ring 842, the rotation of the rotating ring 842 will drive the pressurized air pipe 5 and the cleaning pipe 81 to rotate in the movable groove 843, thereby realizing the rotational movement of the pressurized air pipe 5 and the cleaning pipe 81 within a certain range, so as to perform multi-angle cleaning of the inspection chamber 3.

[0030] In specific work: Pipeline fixing: Both the pressurizing air pipe 5 and the cleaning pipe 81 are fixedly connected to the rotating ring 842. The rotating ring 842 is installed inside the inspection chamber 3 to achieve synchronous fixing of the pressurizing air pipe 5 and the cleaning pipe 81, ensuring that their rotation movements are consistent. Rotation guide: Two movable slots 843 are opened on the side wall of the inspection chamber 3, which are movably connected to the pressurized air pipe 5 and the cleaning pipe 81 respectively. The movable slots 843 provide a guide trajectory for the rotation of the pressurized air pipe 5 and the cleaning pipe 81, so as to avoid the pipes from deviating or getting stuck during the rotation. Power transmission: The drive component 844 at the top of the base plate 841 drives the rotating ring 842 to rotate. The rotating ring 842, with the pressurized air pipe 5 and the cleaning pipe 81, rotates synchronously along the movable groove 843, realizing precise adjustment of the airflow injection / extraction position. The rotation angle can be adjusted according to cleaning needs.

[0031] In this embodiment, through the cooperation of the base plate 841, the rotating ring 842, the movable groove 843 and the driving component 844, the pressurized air pipe 5 and the cleaning pipe 81 are fixedly connected to the rotating ring 842 to achieve synchronous rotation. This ensures that the airflow injection and suction positions are matched in coordination during the cleaning process, improves cleaning efficiency, and avoids impurity residue. The movable groove 843 provides precise guidance for the rotation of the pipe, avoids jamming or deviation during the rotation of the pipe, ensures smooth rotation, and improves the stability of the device operation.

[0032] Example 5 refer to Figure 7 As shown, the drive component 844 includes: The drive motor 8441 is located on the top of the base plate 841. The output end of the drive motor 8441 is equipped with a drive gear 8442. The side wall of the inspection chamber 3 is equipped with a moving groove 8443. Two connecting blocks 8444 that move inside the moving groove 8443 are fixedly connected to the side wall of the rotating ring 842. The side walls of the two connecting blocks 8444 are equipped with driven gears 8445. The drive gear 8442 meshes with the driven gear 8445.

[0033] By configuring a drive motor 8441, a drive gear 8442, a moving groove 8443, a connecting block 8444, and a driven gear 8445, when the drive assembly is working, the drive motor 8441 starts, driving the drive gear 8442 to rotate. Since the drive gear 8442 and the driven gear 8445 are engaged, the rotation of the drive gear 8442 will drive the driven gear 8445 to rotate. The driven gear 8445 is fixed on the connecting block 8444, and the connecting block 8444 is connected to the rotating ring 842, thereby driving the rotating ring 842 to rotate. The rotation of the rotating ring 842 will then cause the pressurized air pipe 5 and the cleaning pipe 81 to rotate in the moving groove 843, thereby achieving multi-angle cleaning of the inspection chamber 3.

[0034] In specific work: Power output: The drive motor 8441 on the top of the base plate 841 starts, and the output end drives the drive gear 8442 to rotate. The drive gear 8442 meshes with the driven gear 8445, and transmits power to the driven gear 8445. Force transmission: The driven gear 8445 is fixed to the side wall of the two connecting blocks 8444. The connecting blocks 8444 are fixed to the side wall of the rotating ring 842 and move within the moving groove 8443 on the side wall of the inspection chamber 3. The moving groove 8443 provides a moving guide for the connecting blocks 8444. When the driven gear 8445 rotates, it drives the connecting blocks 8444 to move along the moving groove 8443, thereby driving the rotating ring 842 to rotate around the axis of the inspection chamber 3. Angle control: The rotating ring 842 is precisely rotated through gear transmission, which in turn drives the pressurized air pipe 5 and the cleaning pipe 81 to precisely adjust their rotation positions to adapt to different cleaning needs.

[0035] In this embodiment, through the cooperation of the drive motor 8441, drive gear 8442, moving groove 8443, connecting block 8444, and driven gear 8445, the drive motor 8441, in conjunction with the gear transmission, achieves a precise transmission ratio and can accurately control the rotation angle and speed of the rotating ring 842. This enables precise positioning of the pressurized air pipe 5 and the cleaning pipe 81, improving the targeting and effectiveness of cleaning. The connecting block 8444, in conjunction with the moving groove 8443, provides precise guidance for the rotation of the rotating ring 842, preventing the rotating ring 842 from deviating during rotation and further improving rotational stability.

[0036] Example 6 refer to Figure 4 As shown, a sealing cover 9 is provided at the bottom of the base plate 841, and the sealing cover 9 is adapted to the top of the camera.

[0037] By setting a sealing cover 9, which is adapted to the top of the camera, when the inspection chamber descends to the detection position, the sealing cover 9 at the bottom of the base plate 841 fits precisely with the top of the camera, so that the base plate 841 and the sealing cover 9 are sealed together, thereby sealing the inspection chamber 3 and the camera, providing a stable detection environment for the air pressure difference detection of the camera sealing ring installation status.

[0038] In this embodiment, the sealing cover 9 improves the sealing between the inspection chamber 3 and the camera, providing stable support for the sealed environment between the inspection chamber 3 and the camera.

[0039] Example 7 refer to Figure 3 As shown, a solenoid valve 10 is installed in the middle of both the pressurizing air pipe 5 and the cleaning pipe 81. The solenoid valve 10 is used to close the pressurizing air pipe 5 and the cleaning pipe 81 to keep the inspection chamber 3 in a sealed state.

[0040] By setting up solenoid valve 10, the solenoid valve 10 located in the middle of the pressurization pipe 5 and the cleaning pipe 81 is in the open state under normal conditions, ensuring the unobstructed flow of air in the supply pipe and the extraction pipe, realizing the delivery of clean gas and the extraction of dust and impurities. When pressure detection is required to determine the sealing status of the sealing ring at the camera lens, solenoid valve 10 closes, making the inspection chamber 3 in a sealed state. At this time, the pressure monitoring module 6 can accurately detect the pressure change in the inspection chamber and determine whether the sealing ring is installed in place and whether the seal is tight based on the pressure change.

[0041] In specific work: Cleaning stage: Solenoid valve 10 is opened, pressurized air pipe 5 and cleaning pipe 81 are in the conductive state, air pump 82 and dust collection equipment 83 supply air to and extract air to inspection chamber 3 through pipelines to complete the cleaning operation; Testing Phase: After cleaning is completed, the control system controls the solenoid valve 10 at the cleaning pipe 81 to close, and the pressurized air pipe 5 delivers the rated air pressure into the inspection chamber 3. After the cleaning is completed, the solenoid valve 10 at the pressurized air pipe 5 closes, and the pressurized air pipe 5 and the cleaning pipe 81 are completely closed. The inspection chamber 3 forms a sealed space through the sealing cover 9, the bottom plate 841 and other structures. The pressure monitoring module 6 can accurately monitor the changes in indoor air pressure and determine the installation status of the sealing ring.

[0042] In this embodiment, the solenoid valve 10 can precisely control the opening and closing of the pressurized air pipe 5 and the cleaning pipe 81, ensuring normal gas flow during the cleaning stage and sealing the inspection chamber 3 during the pressure detection stage. This provides reliable airflow control for different working stages. By closing the solenoid valve 10 to seal the inspection chamber, external gas interference is avoided, allowing the pressure monitoring module 6 to perform detection in a stable environment. This greatly improves the accuracy and reliability of pressure detection, thereby more accurately determining the sealing status of the sealing ring at the camera lens.

[0043] Example 8 refer to Figure 2 As shown, a lifting frame 11 is provided on the top of the testing platform 1. An air pump 82 and a dust collection device 83 are both located in the middle of the lifting frame 11. A top plate 12 is provided on the top of the testing platform 1. A lifting cylinder 13 is provided at the bottom of the top plate 12. The lifting cylinder 13 is fixedly connected to the lifting frame 11.

[0044] By setting up a lifting frame 11, a top plate 12, and a lifting cylinder 13, the top of the inspection platform 1 is equipped with a lifting frame 11, and the air supply equipment and dust collection equipment 83 are set in the middle of the lifting frame 11. The lifting cylinder 13 at the bottom of the top plate 12 extends and retracts, driving the lifting frame 11 and the air supply equipment and dust collection equipment 83 to move up and down as a whole, so as to achieve sealed contact and separation between the inspection chamber 3 and the camera.

[0045] In specific work; Start the lifting cylinder 13, and its output end can extend and retract to drive the inspection chamber 3 to move up and down. Before the test, the inspection chamber rises to facilitate the placement of the camera to be tested. During the test, the inspection chamber 3 descends so that the sealing cover 9 fits against the top of the camera to form a sealed space. After the test is completed, the inspection chamber 3 rises to facilitate the removal of the camera. In this embodiment, through the cooperation of the lifting frame 11, the top plate 12 and the lifting cylinder 13, the lifting cylinder 13 drives the inspection chamber 3 to rise and fall smoothly, which can ensure that the sealing cover 9 is precisely fitted with the top of the camera, improve the sealing reliability, and avoid product damage caused by hard contact.

[0046] Example 9 refer to Figure 4 As shown, the interior of the inspection chamber 3 is equipped with a ring light 14, which is used to improve the brightness inside the inspection chamber 3.

[0047] By setting up a ring light 14 inside the inspection chamber, the ring light 14 is powered on and illuminates during the inspection process, providing uniform and sufficient light to the interior of the inspection chamber 3. Sufficient light enables the vision device to obtain image information of the camera lens and appearance more clearly, improving the clarity and contrast of the image, thereby helping to more accurately detect defects and problems in the appearance of the camera.

[0048] In specific work: Lighting assistance: The ring light 14 is installed inside the inspection chamber 3 (preferably around a vision device or camera lens). During the inspection phase, the ring light 14 is turned on. The light emitted by the ring light 14 evenly covers the surface of the camera lens and the sealing ring area, eliminating shadows and reflections. Improve image quality: Sufficient and uniform light can make the images captured by the vision device clearer, accurately identify tiny stains, scratches and the installation outline of the sealing ring on the lens surface, and avoid missing defects due to insufficient light. In this embodiment, the ring light 14 covers the camera lens and sealing ring area with no blind spots, ensuring comprehensive detection. Uniform illumination eliminates shadows and reflections, making the images captured by the vision device clearer and enabling accurate identification of minute defects. This avoids misjudgments and omissions caused by insufficient light, thus improving the accuracy of lens appearance inspection.

[0049] Example 10 refer to Figure 4 As shown, the bottoms of both the booster pipe 5 and the cleaning pipe 81 are tilted towards the camera lens.

[0050] By setting the bottom of both the pressurized air pipe 5 and the cleaning pipe 81 to be tilted towards the lens of the camera, the airflow delivered by the pressurized air pipe 5 can be delivered to the lens of the camera, and the airflow after colliding with the camera can be extracted, thus improving the cleanliness of the camera lens.

[0051] It should be noted that this invention is a visual inspection device for new energy camera production. In use, the camera is first placed inside the placement seat 2. The lifting cylinder 13 drives the inspection chamber 3 downwards to align with the camera, creating a sealed space between the inspection chamber 3 and the camera. Then, the pressurization pipe 5 delivers high-pressure airflow into the inspection chamber 3, while the cleaning pipe 81 simultaneously starts suction. The high-pressure airflow sweeps the surface of the vision device lens and the camera lens, removing adhering dust, oil, and other impurities. The cleaning pipe 81 then quickly extracts the impurities from the inspection chamber 3. Through the coordinated operation of "air supply + air extraction," dual cleaning is achieved. The servo motor starts, driving the drive gear 8442 to rotate. Since the drive gear 8442 meshes with the driven gear 8445, the rotation of the drive gear 8442 drives the driven gear 8445 to rotate. The driven gear 8445 is fixed to the connecting block 8444, which is connected to the rotating ring 842, thus driving the rotating ring 842 to rotate. The rotation of the rotating ring 842, in turn, causes the pressurized air pipe 5 and the cleaning pipe 81 to rotate within the movable groove 843, thus cleaning the pressurized air pipe 5 and the cleaning pipe 81. Pipe 81 cleans the camera and vision device from different angles. After cleaning, the pressurized air pipe 5 supplies gas into the inspection chamber 3 to maintain the rated air pressure. The pressurized air pipe 5 and cleaning pipe 81 are then closed to seal the inspection chamber 3. The drive mechanism moves the vision device to adjust its inspection position and perform a full-range visual image capture of the camera lens surface, acquiring images of the lens appearance (identifying defects such as stains and scratches). Simultaneously, the pressure monitoring module 6 monitors the air pressure changes in the inspection chamber 3 in real time, using the principle of air pressure difference to determine the installation status of the sealing ring. If the sealing ring is installed correctly, the inspection chamber 3 has good sealing performance, and the air pressure remains stable. If the sealing ring is not installed correctly, is offset, or is missing, air will be present in the inspection chamber 3, and the air pressure will drop rapidly, thus accurately determining whether the sealing ring installation is qualified. At the same time, the tracking inspection mechanism 7 adjusts the vision inspection device 4 to tilt it towards the sealing ring and rotates it to track and inspect each part of the sealing ring. Through the dual inspection of air pressure difference and vision, the installation status of the camera sealing ring, whether it is installed correctly, and the sealing performance can be accurately checked.
