Description

Technical Field

[0001] This invention relates to the field of ceramic defect detection technology, specifically to a conveying and guiding structure for detecting defects in the forming of special ceramics. Background Technology

[0002] The special ceramic forming defect detection device is a non-destructive intelligent inspection device for the ceramic green body forming stage. It integrates conveying, imaging acquisition, AI recognition and sorting modules, and uses technologies such as X-ray, ultrasound and vision to non-contactly identify internal and external defects such as microcracks, pores, delamination, deformation, and inclusions in green bodies. The device automatically collects component imaging data, quantifies the defect size and locates the defect position through algorithms, quickly distinguishes good products from defective parts and automatically sorts them, making up for the shortcomings of manual visual inspection. Defective green bodies are removed before sintering, reducing the scrap rate in subsequent processing. It is suitable for batch online quality inspection of various special ceramics such as alumina and silicon nitride, ensuring stable green body forming quality.

[0003] However, existing special ceramic defect detection devices require manual adjustment of their positioning guide during use, which leads to low positioning calibration efficiency and easy occurrences of workpiece displacement and detection point deviation, thereby affecting the accuracy of special ceramic defect detection and the overall efficiency of the detection operation.

[0022] Defect Detection Device 112: Model UST-56CM optional. The main unit controls the top column to move the ultrasonic probe down to fit the ceramic workpiece. The probe emits high-frequency ultrasonic waves that penetrate the ceramic matrix. The sound wave reflection signal is weak in dense areas of the material, while strong reflection echoes are generated at pores, cracks, and delamination. The main unit collects the echo signals and converts them into image data, automatically marking the defect location and size.

[0023] It should be noted that the control of the conveyor frame 111 and the motor 216 in this application can be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0024] In use, the special ceramic to be inspected can be conveyed to the defect detection device 112 via the conveyor frame 111. Before conveying, the motor 216 is started, and the motor 216 drives the connecting rod 218 to rotate via the rotating shaft 217. Then, with the hinged linkage of the two connecting rods 214, the two slide plates 213 are driven to move closer to each other under the guidance of the two sliding rods 212. This allows the two slide plates 213 to drive the elastic parts 3 on them to move synchronously, thereby achieving the centering and positioning of the special ceramic. During the positioning process, the slide frames 312 on the two slide plates 213 are slidably connected by multiple sliding rods 311, which will drive multiple guide rollers 313 on them. With the elastic cooperation of the telescopic rod 321 and the spring 322, the two slide frames 312 can provide a certain buffer space for the special ceramic with the help of multiple guide rollers 313, avoiding damage to the ceramic surface caused by hard clamping. Meanwhile, when it is necessary to adjust the guide angle of the guide plate 411 at the feed inlet of the two slide frames 312, the knob 417 can be rotated to drive the screw 416 to rotate within the fixed block 415, thereby pushing the U-shaped block 414. Under the sliding guide cooperation of the slide groove 421 and the slide rod 422, the U-shaped block 414 can be driven by the connecting rod 413 and the rotating rod 412, which are hinged to it. This allows the guide plate 411 on the rotating rod 412 to rotate to the required angle with the slide frame 312 as the fulcrum. The guide plate 411 on the other side can be adjusted separately according to the same steps, thereby meeting the guidance requirements under different sizes or feeding postures.
