[0032] Example 1
[0033] like Figures 1-4This utility model provides a ceramic product defect detection device, including a frame 100. A drive roller 120 and a motor 110 that drives the drive roller 120 to rotate are rotatably mounted on the top of the frame 100. A driven roller 130 is rotatably mounted on the top of the frame 100. A conveyor belt 140 is fitted around the drive roller 120 and the driven roller 130. The motor 110 drives the drive roller 120 to rotate. The drive roller 120 and the driven roller 130 cooperate to realize the rotation of the conveyor belt 140, providing power for the conveying of ceramic products on the detection device, so that the ceramic products can move on the detection device, which facilitates subsequent detection operations.
[0034] A rectangular shell 200 is mounted on the top of the frame 100. Through holes 201 are provided on the bottom of both the left and right sides of the rectangular shell 200. An image acquisition component 210 is installed on the inner wall of the rectangular shell 200. The rectangular shell 200 provides installation space for the image acquisition component 210 and protects the internal image acquisition component 210. At the same time, the through holes 201 on the bottom of the left and right sides allow ceramic products to pass through the inside of the rectangular shell 200 via the conveyor belt 140 so that the image acquisition component 210 can acquire images of the ceramic products.
[0035] A smart controller 300 is installed on the front side wall of the rectangular shell 200.
[0036] Image acquisition components 210 are installed on the middle of the front and rear side walls and the top of the rectangular shell 200. Image acquisition components 210 are also installed at the four corners of the inner wall of the rectangular shell 200 at a downward angle. By installing image acquisition components 210 on the middle of the front and rear side walls, the top of the rectangular shell 200, and the four corners of the inner wall, images of ceramic products can be acquired from multiple angles and positions, realizing all-round inspection of ceramic products, improving the accuracy and comprehensiveness of inspection, and reducing blind spots in inspection.
[0037] Each image acquisition component 210 includes at least one camera 211 and at least one illumination lamp 212. The camera 211 is electrically connected to the intelligent controller 300, which is mounted on the front side wall for easy operation and control. The intelligent controller 300 is used to receive and process the image information acquired by the image acquisition component 210, analyze and judge whether there are defects in the ceramic products, and realize intelligent control of the entire detection device. The camera 211 is used to acquire image information of the ceramic products and convert the images into electrical signals for transmission to the intelligent controller 300 for analysis. The illumination lamp 212 provides stable illumination to ensure that the camera 211 can clearly capture the surface details of the ceramic products under different ambient light conditions, improve the quality of image acquisition, and thus improve the accuracy of defect detection.
[0038] A crossbeam 101 is fixedly installed on the top of both the front and rear sides of the frame 100. The driving roller 120 and the driven roller 130 are rotatably installed inside the two crossbeams 101. The bottom of the rectangular shell 200 is stuck outside the crossbeam 101. The crossbeam 101 provides a mounting support structure for the driving roller 120 and the driven roller 130, ensuring the stability of their rotation. At the same time, the bottom of the rectangular shell 200 is stuck outside the crossbeam 101, realizing the installation and fixation of the rectangular shell 200, making the connection between the rectangular shell 200 and the frame 100 more stable, and ensuring the stability of the overall structure of the detection device.
[0039] Rubber wheels 150 are rotatably mounted on the top of the crossbeam 101. When ceramic products move on the conveyor belt, the rubber wheels 150 can play a role in auxiliary support and guidance, reducing the shaking and deviation of ceramic products during the conveying process, ensuring that the ceramic products pass smoothly through the rectangular shell 200 for inspection. At the same time, the material of the rubber wheels 150 can also avoid damaging the surface of the ceramic products.
[0040] The spacing between the driven rollers 130 is one to five centimeters. This appropriate spacing ensures the tension and stability of the conveyor belt 140, preventing it from becoming loose or slipping during rotation. This ensures that the ceramic products can move stably on the conveyor belt and pass smoothly through the inspection area.
[0041] The intelligent controller 300 is equipped with a buzzer alarm 310. When the intelligent controller 300 analyzes and determines that there is a defect in the ceramic product, the buzzer alarm 310 can sound an alarm to remind the operator that there is a problem with the ceramic product so that it can be dealt with in a timely manner, thereby improving the efficiency of detection and the timeliness of production quality control.
[0042] The process of the image acquisition component 210 acquiring images of ceramic products is as follows:
[0043] Positioning and omnidirectional coverage: The image acquisition component 210 is installed at the middle of the front and rear side walls, the top, and the four corners of the inner wall of the rectangular shell 200, and is tilted downwards. This layout allows the image acquisition component 210 to observe and photograph ceramic products from multiple different angles, achieving omnidirectional coverage of the ceramic product surface, avoiding blind spots, and ensuring that image information can be acquired from all parts of the ceramic product.
[0044] Image capture by the camera: Each image acquisition component 210 contains at least one camera 211. When the ceramic product enters the rectangular shell 200 along the conveyor belt 140, the camera 211 starts working and converts the optical information of the ceramic product surface into electrical signals through the principle of optical imaging.
[0045] The lighting provides stable illumination: Each image acquisition component 210 is also equipped with at least one lighting lamp 212. During the image acquisition process of ceramic products, the lighting lamp 212 provides stable and uniform illumination, ensuring sufficient brightness and contrast on the surface of the ceramic product. This helps the camera 211 to capture the details of the ceramic product surface more clearly, including potential defects such as cracks, pores, and uneven color. Even under poor ambient lighting conditions, the acquired image quality is guaranteed to be high, facilitating subsequent analysis and judgment.
[0046] Image transmission and processing: The image data acquired by the camera 211 is transmitted to the intelligent controller 300 in the form of electrical signals via a connecting cable. The intelligent controller 300 processes this image data, including image enhancement, noise reduction, and feature extraction, in order to more accurately analyze and determine whether there are defects in the ceramic products, as well as the type and location of the defects.
[0047] It should be noted that the intelligent controller 300 processes these image data, including image enhancement, noise reduction, and feature extraction, which are existing technologies and will not be described in detail here.
[0048] In summary, this ceramic product defect detection device uses a motor 110 to drive the active roller 120, which in turn works with the driven roller 130 to drive the conveyor belt 140, thereby achieving stable conveying of ceramic products.
[0049] The rectangular shell 200 provides installation space for the graphic acquisition component 210, and the through holes 201 on both sides facilitate the passage of the product.
[0050] The multi-angle-mounted image acquisition component 210, together with the illumination lamp 212, can acquire clear images from all directions, improving detection accuracy.
[0051] The crossbeam 101 supports the drive roller, driven roller, and rectangular shell, while the rubber wheel 150 assists in conveying the product and ensures stable product delivery.
[0052] The driven rollers 130 are spaced one to five centimeters apart to ensure stable tension of the conveyor belt.
[0053] The 310 buzzer alarm sounds when the intelligent controller detects a defect, reminding operators to handle it promptly and improving detection efficiency.
[0054] The following are the specific model numbers of the electrical appliances in this solution:
[0055] Motor 110: A MINASA 6 series servo motor, such as MSMD042G1U, can be selected. It features high torque, high precision and fast response, which can ensure the stable and accurate operation of the conveyor belt 140.
[0056] Camera 211: We recommend the DS-2CD2T46FWD-I5 4-megapixel network camera, which boasts high resolution and excellent low-light performance, and can clearly capture the surface details of ceramic products.
[0057] Lighting lamp 212: Uses Duluxstar LED T8 lamp tube, which has the characteristics of high brightness and uniform light emission, and can provide stable lighting conditions for camera 211 to ensure the quality of captured images.
[0058] Intelligent Controller 300: S7-1200 series PLC controller, with powerful computing capabilities and rich interfaces, can be easily connected to devices such as camera 211, motor 110 and buzzer alarm 310 to achieve precise control and data processing of the entire detection process.
[0059] Buzzer Alarm 310: Can be equipped with AD16-22SM audible and visual alarm, with a wide operating voltage range (AC220V / AC380V / AC24V / AC36V / AC110V / DC24V, etc.), and a sound level of up to 106dB, which can clearly emit alarm signals in noisy production environments.
[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
