Description

Technical Field

[0001] This utility model relates to the field of visual inspection device technology, and in particular to a visual inspection device for motor coils. Background Technology

[0002] A visual inspection device for motor coils is a device used to automatically identify and inspect the quality of coils. It uses image processing technology to inspect the appearance, defects, and parameters of the coils to ensure that they meet production standards. In the current market, the manufacturing process of coils is all done manually, which mainly includes straightening, twisting, cutting, and tinning the copper wires at the coil terminals, as well as inspecting the coil's resistance, withstand voltage, inductance, etc. In addition, existing motor coils are manufactured in different models according to the design requirements of the motor.

[0003] Therefore, while existing visual inspection devices for motor coils offer a certain degree of automation and accuracy, different inspection chambers may be required for inspecting different models of motor coils. A Chinese patent, application number "202323079232.4," discloses a "visual inspection device for motor coils." This device reduces blind spots by eccentrically rotating the coil and using a side camera to capture images of the coil from multiple angles. Furthermore, it only involves rotating the turntable and moving the side camera for focusing, resulting in relatively low control complexity and manufacturing costs. The inspection process is fully automated, with high positioning accuracy for the side camera and turntable, ensuring complete consistency in the images of each coil and reducing image processing difficulty. While this device improves inspection accuracy, it cannot inspect different models of motor coils. Therefore, to further improve the practicality of the device, we provide a visual inspection device for motor coils to address the aforementioned problems. Utility Model Content

By symmetrically arranging LED light panels on the inner surface of the inspection chamber, combined with a ring-shaped supplementary light directly above the top of the inspection chamber, the entire inspection area can obtain uniform illumination, reducing shadows and light spots, avoiding image quality degradation caused by uneven lighting, improving image detail and contrast, and enabling the visual inspection camera to more accurately identify the edges and defects of objects. Furthermore, by using an ultrasonic sensor to identify the motor coil, the distance between the electric telescopic rod and the motor coil can be adjusted, as well as the shooting angle between the visual inspection camera and the motor coil, thereby improving the flexibility and applicability of motor coil inspection and reducing the false detection rate.

[0022] Reference Figure 1-4 This utility model discloses a visual inspection device for motor coils, comprising: a workbench 1 for setting and fixing inspection chamber 3, conveyor belt 2, and other facilities; the inspection chamber 3 is fixedly connected to the upper surface of the workbench 1, allowing the motor coil to move to the inspection area via the conveyor belt 2 of the conveyor system, entering the inspection position directly below the support plate 9; and a visual inspection camera 10 captures the image of the coil, ensuring a clear image through the cooperation of a supplementary light 11 and an LED light panel 13. The acquired image is analyzed by an image processing unit and uploaded to a display panel 4. A servo motor 5 is fixedly connected to the upper surface of the inspection chamber 3, providing power for the meshing motion of gear 6 and gear 7. Gear 6 is fixedly connected to the output end of the servo motor 5 via a shaft, and gear 7 meshes with the surface of gear 6, causing the electric telescopic rod 8 to rotate under the interaction of the two. An electric telescopic rod 8 is used to adjust the appropriate distance between the visual inspection camera 10 connected to the support plate 9 and the motor coil, making the inspection image more accurate and the data more precise. The output end of the electric telescopic rod 8 passes through the inspection chamber 3 and is fixedly connected to the support plate 9, which is used to set up an annular slide 91 and a supplementary light 11. The inner bottom surface of the support plate 9 has an annular slide 91, which is used to allow the visual inspection camera 10 to perform all-round inspection of the object to be inspected. The visual inspection camera 10 is slidably connected to the inside of the annular slide 91 through an electric slider, which is used to automatically identify and inspect the quality of the motor coil. The visual inspection camera 10 and the electric slider are rotatably connected, which facilitates the adjustment of the optimal shooting angle between the visual inspection camera 10 and the motor coil by the ultrasonic sensor 15. The supplementary light 11 is fixedly connected to the outer surface of the support plate 9, which is used to provide uniform and diffused lighting, reduce shadows and reflections, and ensure consistent image quality from different angles.

[0023] The electric telescopic rod 8 is rotatably connected to the top surface of the testing chamber 3. The electric telescopic rod 8 is located at the center of the testing chamber 3 to facilitate the rotation of the support plate 9 and to ensure the accurate identification of the position and size of the motor coil by the ultrasonic sensor 15. A conveyor belt 2 is provided on the upper surface of the workbench 1. A storage box 12 is fixedly connected to one side of the workbench 1. The storage box 12 is located below the conveyor belt 2 and is used to transport the motor coil to the testing chamber 3 for testing. After the testing is completed, the coil is transported to the storage box 12 for the next process. An LED light panel 13 is fixedly connected to the inner side of the inspection chamber 3, and a display panel 4 is fixedly connected to the front surface of the inspection chamber 3. Warning lights are installed on the sides of the display panel 4 to upload images and data of the motor coil after inspection. If any defects are found, the warning lights will promptly alert the inspectors. The camera of the visual inspection camera 10 is concentrated at the center of the conveyor belt 2. A supplementary light 11 is located at the lower end of the outer surface of the support plate 9 to highlight the edges and details of the motor coil, enhance image contrast, and make defects easier to identify. Light-blocking curtains 14 are fixedly connected to both sides of the inspection chamber 3. The light-blocking curtains 14 have an opening and closing slit in the center, and their bottom surfaces are connected to the worktable. 1. The conveyor belt 2 is in contact with the light source inside the detection chamber 3 to prevent external light sources from affecting the internal light source and causing errors in the detection data. It also facilitates the input and output of the motor coil on the conveyor belt 2. An ultrasonic sensor 15 is fixedly connected to the inner bottom surface of the support plate 9. The ultrasonic sensor 15 is located directly above the center of the conveyor belt 2 to facilitate the identification of the size and model of the motor coil. This allows the electric telescopic rod 8 to adjust the height of the support plate 9 and the visual inspection camera 10, thereby detecting different models of motor coils and improving the adaptability of the detection device. The support plate 9 is circular in shape, and its diameter is the same as the width of the conveyor belt 2 to facilitate the detection of different models of motor coils.

[0024] Working principle: When using the visual inspection device for this motor coil, the motor coil enters the inspection chamber 3 through the light-shielding curtain 14 connected to the conveyor belt 2 on the upper surface of the workbench 1, and is transported to the monitoring area. The ultrasonic sensor 15 identifies the model and position of the motor coil. Based on the measurement data of the ultrasonic sensor 15, the electric telescopic rod 8 automatically adjusts its position and moves it to the appropriate position of the motor coil. The visual inspection camera 10 adjusts to the best shooting angle with the motor coil. At the same time, combined with the function of the supplementary light 11 and the LED light board 13, the servo motor 5 drives the gear 6 and gear 7, which in turn drives the electric telescopic rod 8 connected to gear 7 to rotate. This drives the supplementary light 11 connected to the support plate 9 to rotate, avoiding the situation where the opening and closing of the light-shielding curtain 14 affects the lighting requirements in the inspection chamber 3. After the motor coil is inspected, it is transported to the storage box 12 by the conveyor belt 2.
