[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] With the development of modern manufacturing, the quality inspection of air conditioner fan blades has become an indispensable part of the production process. Traditional inspection methods often rely on manual visual inspection, which is not only inefficient but also easily affected by human factors, resulting in low accuracy of the inspection results. To solve this problem, this embodiment proposes an image inspection device for air conditioner fan blades, which uses visual inspection technology to achieve automated and high-precision inspection of air conditioner fan blades.

[0032] like Figures 1-2 As shown, an image inspection device for air conditioner fan blades includes: an industrial control computer 1 for inspecting products; the industrial control computer 1 includes a vision inspection device 2 for image inspection of the products; the industrial control computer 1 is responsible for receiving image data from the vision inspection device 2, processing and analyzing it to determine whether the quality of the air conditioner fan blades meets the requirements. The industrial control computer 1 has a built-in high-performance processor and a large-capacity storage device, which can ensure the efficiency and stability of data processing.

[0033] The visual inspection device 2 includes an imaging device 3 and a sensor 4. The sensor 4 is electrically connected to the imaging device 3. The sensor 4 is used to sense the position of the product, and the imaging device 3 is used to identify and photograph the product, clearly capturing the detailed features of the air conditioner fan blades. By adjusting the camera's focal length, exposure, and other parameters, the quality of the captured image can be ensured to meet the inspection requirements. The imaging device 3 transmits the captured image data to the industrial control computer 1 in real time for processing. The sensor 4 is used to sense the position of the air conditioner fan blades, ensuring that the imaging device 3 can photograph the product from the correct position and angle. The sensor 4 is electrically connected to the imaging device 3. When the sensor 4 detects that the air conditioner fan blades have reached the predetermined position, it sends a signal to the imaging device 3 to trigger the shooting action. The high precision and fast response capability of the sensor 4 ensure that the imaging device 3 captures the best image data.

[0034] During the testing process, the air conditioner fan blades are placed on the workbench of the testing device and transported into the testing area via a conveyor belt or other conveying device. Sensor 4 monitors the position of the air conditioner fan blades in real time, and when the product is detected to have reached the predetermined position, it sends a shooting signal to the shooting device 3. Upon receiving the signal, the shooting device 3 immediately takes a picture of the air conditioner fan blades and transmits the captured image data to the industrial control computer 1.

[0035] After receiving image data, the industrial control all-in-one computer 1 processes and analyzes the image using its built-in image processing algorithms. By extracting and matching features in the image, it can determine whether the air conditioner fan blades have defects or whether their dimensions are up to standard. If the detection results do not meet the requirements, the industrial control all-in-one computer 1 will issue an alarm signal and display the specific detection results and defect locations so that operators can handle the situation promptly.

[0036] By combining sensor 4 and imaging device 3, automated inspection of air conditioner fan blades is achieved, greatly improving inspection efficiency. At the same time, the high-resolution industrial camera and advanced image processing algorithm can capture minute defects on the surface of the air conditioner fan blades, ensuring the accuracy of the inspection results.

[0037] Example 1

[0038] like Figures 2-3 As shown, one embodiment of this utility model proposes an air conditioner fan blade image detection device to improve the accuracy and flexibility of air conditioner fan blade image detection. The imaging device 3 includes a CCD camera 301 and a lens 302. The lens 302 is mounted on the CCD camera 301. The focal length of the lens 302 is adjusted by the CCD camera 301. The shooting focal length is adjusted by changing the physical length of the lens 302, thereby achieving clear imaging of air conditioner fan blades of different distances and sizes. The lens 302 is also equipped with a focal length adjustment knob or electronic adjustment interface so that the operator can fine-tune the focal length according to actual needs. The CCD camera 301 is used to capture images of the product.

[0039] During the shooting process, lens 302 first adjusts its focus based on the position and size of the air conditioning fan blades transmitted by sensor 4. The operator can determine the optimal focus setting by observing the preview image or using the autofocus function. After the focus adjustment is complete, CCD camera 301 begins to capture images of the air conditioning fan blades.

[0040] The CCD camera 301 converts the captured image data into electrical signals and transmits them to the industrial control computer 1 for processing via a data cable. The industrial control computer 1 uses its built-in image processing algorithms to perform preprocessing, feature extraction, and defect detection on the images, ultimately obtaining the detection results.

[0041] Lens 302 is equipped with a focus adjustment knob or electronic adjustment interface, allowing operators to fine-tune the focus according to actual needs to adapt to air conditioning fan blades of different sizes and shapes.

[0042] Example 2

[0043] like Figures 4-5 As shown, in another embodiment of the present invention, in order to optimize the lighting conditions of the shooting device 3, the shooting device 3 further includes a light source 303, which is used to assist the CCD camera 301 in recognition, and the light source 303 is disposed on the side of the CCD camera 301 away from the lens 302; the vertical projection of the light source 303 is on the industrial control all-in-one computer 1.

[0044] The light source 303 employs high-performance lighting equipment such as LED lamps, halogen lamps, or xenon lamps, providing stable and uniform illumination. In this embodiment, the light source 303 is positioned on the side of the CCD camera 301 furthest from the lens 302 to ensure uniform illumination of the air conditioner fan blade surface, while preventing glare or reflections from direct light hitting the lens 302. The brightness and color temperature of the light source 303 can be adjusted according to actual needs to adapt to different air conditioner fan blade materials and different shooting environments. By precisely controlling the illumination intensity and direction of the light source 303, the shooting effect can be further optimized and image quality improved.

[0045] During the shooting process, the light source 303 illuminates according to the signal transmitted by the sensor 4, providing stable and uniform lighting conditions. After receiving sufficient light, the CCD camera 301 begins to capture images of the air conditioner fan blades. The illumination intensity and direction of the light source 303 can be adjusted according to actual needs to optimize the shooting effect.

[0046] The industrial control integrated computer 1 receives image data from the CCD camera 301 and performs preprocessing, feature extraction, and defect detection. Due to the optimized configuration of the light source 303, the quality of the captured images is significantly improved, thereby enhancing the accuracy and reliability of defect detection.

[0047] The configuration of light source 303 ensures that the captured images are clear and bright, accurately reflecting the surface characteristics of the air conditioner fan blades. This helps operators more accurately judge the quality of the product. The brightness and color temperature of light source 303 can be adjusted according to actual needs to adapt to different materials of air conditioner fan blades and different shooting environments, thereby improving the versatility and flexibility of the shooting device 3.

[0048] Example 3

[0049] like Figure 5 As shown, another embodiment of this utility model is that, in order to improve the stability and flexibility of the shooting device 3, ensure the stable and reliable quality of the captured images, and facilitate operation and maintenance, the shooting device 3 is connected to the industrial control computer 1 through the camera light source fixing plate 5; the camera light source fixing plate 5 is L-shaped, one end of the camera light source fixing plate 5 is connected to the industrial control computer 1, and the other end is connected to the shooting device 3, and the visual inspection device 2 is connected to the industrial control computer 1 at a certain angle.

[0050] The camera light source mounting plate 5 adopts an L-shaped design. One end is fixedly connected to the industrial control all-in-one machine 1 through bolts, nuts and other connecting parts, and the other end is connected to the shooting device 3 (including CCD camera 301, lens 302 and light source 303) through similar connecting parts.

[0051] The visual inspection device 2 (including the imaging device 3 and the sensor 4) is connected to the industrial control computer 1 at a certain angle. This design aims to optimize the shooting angle and lighting conditions to ensure that the captured image accurately reflects the surface features of the air conditioner fan blades. At the same time, the connection angle can be fine-tuned according to actual needs to accommodate air conditioner fan blades of different sizes and shapes.

[0052] The visual inspection device 2 (including the imaging device 3 and the sensor 4) is connected to the industrial control computer 1 at a certain angle, which optimizes the shooting angle and lighting conditions to ensure that the captured image accurately reflects the surface features of the air conditioner fan blades. At the same time, the connection angle can be finely adjusted according to actual needs to adapt to air conditioner fan blades of different sizes and shapes.

[0053] The camera light source mounting plate 5 ensures stable support for the shooting device 3, preventing image blurring or distortion caused by vibration or shaking. The connection angle can be fine-tuned according to actual needs to accommodate air conditioning fan blades of different sizes and shapes, thereby optimizing the shooting effect. The camera light source mounting plate 5 also makes the connection between the shooting device 3 and the industrial control all-in-one machine 1 simpler and faster, while facilitating subsequent operation and maintenance.

[0054] Example 4

[0055] like Figure 6 As shown, another embodiment of this utility model is that the visual inspection device 2 is provided with a light shield 6 to reduce light source interference during the shooting of the visual inspection device 2, and the light shield 6 is connected to the industrial control integrated computer 1.

[0056] The light shield 6 on the visual inspection device 2 is used to block or reduce direct illumination of the shooting area by external light sources, thereby reducing light source interference and image noise. The light shield 6 can also be equipped with an adjustable angle and position for fine-tuning as needed. For reference, the light shield 6 can be designed as a rotatable or sliding structure so that the operator can adjust its angle and position as required.

[0057] The connection between the light-shielding plate 6 and the industrial control all-in-one computer 1 can be fixed or adjustable. In this embodiment, the light-shielding plate 6 is fixedly connected to the industrial control all-in-one computer 1 by connectors (such as bolts, nuts, or clips) to ensure its stability. At the same time, the angle and position of the light-shielding plate 6 can be finely adjusted as needed, so that the operator can adjust it according to actual needs.

[0058] During the shooting process, the light shield 6 is adjusted to a suitable position and angle according to actual needs to block or reduce the direct illumination of the shooting area by external light sources. This helps to reduce light source interference and image noise, improving shooting quality and inspection accuracy. After receiving the shooting command from the industrial control computer 1, the vision inspection device 2 begins to capture images of the air conditioner fan blades. Due to the blocking effect of the light shield 6, the captured image quality is clearer and more stable, accurately reflecting the surface characteristics of the product.

[0059] Example 5

[0060] like Figure 7 As shown, in another embodiment of the present invention, the sensor 4 is disposed on the camera light source fixing plate 5 and below the shooting device 3. The sensor 4 is electrically connected to the light source 303 and transmits signals to control the light source to turn the light source 303 on and off.

[0061] Sensor 4 employs a high-sensitivity photoelectric sensor, capable of rapidly responding to changes in light and object obstruction. When sensor 4 detects insufficient light in the shooting area or an object entering the shooting range, it immediately sends an electrical signal to the light source 303 control system, triggering the light source 303 to turn on; conversely, when shooting is complete or the light is sufficient, sensor 4 sends a signal to turn off the light source 303.

[0062] Sensor 4 is connected to the control system of light source 303 via a dedicated electrical signal line, forming a closed-loop control system. This connection ensures real-time transmission of signals from sensor 4 and immediate response of the control system of light source 303.

[0063] Its working process is as follows: After the shooting device 3 is started, the light source 303 control system and the sensor 4 both enter the initialization state and wait for the shooting command; when an object enters the shooting area or the light changes, the sensor 4 captures these changes and converts them into electrical signals; the sensor 4 transmits the electrical signals to the light source 303 control system; the light source 303 control system determines whether the light source 303 needs to be turned on or off based on the received signal and adjusts the brightness of the light source 303; under suitable lighting conditions, the shooting device 3 takes pictures and records image data; after the shooting is completed, the light source 303 control system turns off the light source 303, and the sensor 4 enters the standby state, waiting for the next shooting command.

[0064] The integration of sensor 4 with the control system of light source 303 enables intelligent control of light source 303, improving the automation of shooting. At the same time, sensor 4 can adjust its position and sensitivity according to actual needs to adapt to the needs of different shooting scenarios.

The light-shielding plate 6 is movably connected to the protective cover 7 via connectors (such as hinges, slide rails, or quick-release latches), ensuring a secure connection between them and allowing for fine-tuning of the light-shielding plate 6's angle and position to adapt to different shooting requirements and lighting conditions. The tight connection between the light-shielding plate 6 and the protective cover 7 creates a sealed optical environment, effectively blocking external light sources from interfering with the visual inspection device 2. Simultaneously, the protective cover 7 provides physical protection for the visual inspection device 2, preventing the intrusion of dust, moisture, and other contaminants, thus extending the device's lifespan.

[0068] The synergistic effect of the light shield 6 and the protective cover 7 effectively reduces interference from external light sources, improving image quality and inspection accuracy. The protective cover 7 provides comprehensive physical protection for the visual inspection device 2, extending its service life and reducing malfunctions and damage caused by environmental factors.

Furthermore, product rack 8 is aligned with the height of vision inspection device 2 and industrial control computer 1, ensuring the product is in the optimal shooting position during the imaging process, thereby improving the accuracy and consistency of the images. The product rack 8, together with vision inspection device 2 and industrial control computer 1, forms a highly efficient and automated inspection system. The operator simply places the product on product rack 8, or directly connects product rack 8 to the production line; vision inspection device 2 automatically performs imaging and inspection, while industrial control computer 1 processes and analyzes the image data, providing accurate inspection results and feedback.

[0072] The design of product rack 8 simplifies the product placement and positioning process, reduces operator intervention, and improves inspection efficiency.

[0075] The visual inspection device 2 is positioned at the center of the ring light source 303, ensuring that it receives uniform light from all angles, thereby capturing high-quality, shadow-free images. This not only improves the accuracy of the shooting but also simplifies the complexity of image processing.

[0076] The uniform light distribution of the ring light source 303 reduces shadows and reflections, improving image clarity and contrast. The visual inspection device 2, located at the center of the light source 303, simplifies the system structure and improves inspection speed and accuracy.

[0077] Example 9

[0079] Alarm light 9 is connected to vision inspection device 2 via an electrical signal (such as a digital or analog signal). When vision inspection device 2 detects abnormalities such as defects, size discrepancies, or color deviations in the product, it immediately sends an electrical signal to alarm light 9, triggering the corresponding alarm state. Industrial control computer 1, as the core control unit of the inspection system, is responsible for processing the image data transmitted by vision inspection device 2 and analyzing and judging it according to preset inspection standards and algorithms. When an abnormality is detected, industrial control computer 1 immediately sends a control signal to alarm light 9 to activate the corresponding alarm state.

[0080] The alarm light 9 is directly connected to the visual inspection device 2 via electrical signals, enabling the system to immediately trigger an alarm when an anomaly is detected, thus improving response speed and accuracy. The alarm light 9 provides an intuitive and rapid alarm indication method, helping operators quickly understand the system's operating status and any abnormalities. By responding to and handling alarms promptly, the system can avoid production interruptions caused by malfunctions or anomalies, improving the stability and continuity of the production process.
