[0049] Working principle: in use, the upper supporting arm 25 in the initial state is located directly below the workpiece groove 21, the zero part to be detected is placed in the workpiece groove 21, at this time the bottom of the zero part is supported by the upper supporting arm 25, and the upper half of the zero part protrudes from the top of the positioning turntable 14, and the driving block 32 and the transverse block 29 are staggered, without clamping the zero part, control the second driving source 9 to drive the first gear 13 to rotate, the first gear 13 drives the rotating disc 3 to rotate by a certain amplitude, so that the zero part to be detected comes to the first sector gear 7 and the second sector gear 20, and at this time the positioning turntable 14 just corresponds to the industrial camera 6, at this time the first sector gear 7 corresponds to the second gear ring 22, then control the first driving source 8 to drive the first sector gear 7 and the second sector gear 20 to rotate as a whole, the first sector gear 7 meshes with the second gear ring 22, and then the first sector gear 7 drives the positioning turntable 14 to rotate one hundred and eighty degrees through the second gear ring 22, during which the upper industrial camera 6 detects the upper surface of the zero part, and when rotating one hundred and eighty degrees, the two industrial cameras 6 at both ends of the side detect the side edge of the upper half of the zero part, then the first driving source 8 continues to control the first sector gear 7 and the second sector gear 20 to rotate as a whole, at this time the first sector gear 7 and the second gear ring 22 are separated, the second sector gear 20 then meshes with the second gear 23, the second gear 23 drives the linkage shaft 30 to rotate one hundred and eighty degrees, and when rotating to less than ninety degrees, the upper supporting arm 25 will be separated from the bottom of the zero part, and the lower supporting arm 26 will be displaced to the bottom of the zero part immediately after, and then the zero part falls to the top of the lower supporting arm 26 under its own weight, and then the lower part of the zero part protrudes from the bottom of the positioning turntable 14, at this time the driving block 32 and the transverse block 29 are still staggered, then due to the continuous rotation of the linkage shaft 30, the lower supporting arm 26 gradually separates from the bottom of the zero part, and before separation, the driving block 32 gradually contacts and pushes the transverse block 29, the transverse block 29 is pressed by the first elastic piece 33, and then the clamping plate 27 is pressed to the side wall of the zero part, at this time the bottom of the zero part is not blocked, so that the lower industrial camera 6 can detect the lower surface of the zero part, then control the first driving source 8 to continue to drive the first sector gear 7 and the second sector gear 20 to rotate as a whole, the first sector gear 7 will mesh with the second gear ring 22 again, and then the first sector gear 7 drives the positioning turntable 14 to rotate one hundred and eighty degrees again through the second gear ring 22, and then the two industrial cameras 6 at the side detect the side of the lower half of the zero part, so as to realize comprehensive detection, and the upstream work station can place the zero part during detection, then the second driving source 9 drives the first gear 13 to continue to rotate, the first gear 13 continues to drive the rotating disc 3 to rotate, so as to continuously convey the upstream zero part to be detected to the detection position, and the detected zero part will pass through the first fixed arm 15 when the rotating disc 3 rotates, so that the second gear 23 meshes with the first gear rack 16, and then the second gear 23 drives the linkage shaft 30 to rotate ninety degrees, at this time the driving block 32 and the transverse block 29 are separated, the first elastic piece 33 is reset,When the pressure of the clamping plate 27 on the side wall of the part disappears, the part falls down through the through hole 19 and the blanking groove 11 under its own weight, and when the subsequent rotation continues, the second gear 23 will engage with the second rack 18, and then the second gear 23 will continue to rotate by 90 degrees, so that the upper supporting arm 25 is again below the workpiece groove 21, so as to facilitate the subsequent feeding;

[0050] The side detection involves step-by-step detection of multiple directions of the part, and a complete circumferential view is constructed through image registration and fusion algorithm, which can effectively identify surface defects such as pores and cracks.

[0051] It should be noted that, in order to prevent the positioning turntable 14 and the linkage shaft 30 from easily rotating, the corresponding damping block 34 will be in contact with the side wall of the linkage shaft 30 and the side wall of the positioning turntable 14 through the roller, thereby increasing the resistance of the linkage shaft 30 and the positioning turntable 14, and avoiding the self-rotation of the positioning turntable 14 and the linkage shaft 30. Since the positioning turntable 14 will also be stressed when the second sector gear 20 engages with the second gear 23, the resistance of the damping block 34 to the positioning turntable 14 and the linkage shaft 30 is configured as follows: when the second sector gear 20 drives the linkage shaft 30 to rotate through the second gear 23, the resistance received by the positioning turntable 14 will not cause the positioning turntable 14 to rotate, thereby ensuring the stability of the positioning turntable 14 and the linkage shaft 30.

[0052] The rack 1 is provided with an industrial control box 10, which is electrically connected with the first driving source 8, the second driving source 9, the industrial camera 6 and the like. The industrial control box 10 also has a multi-source data acquisition and synchronization module, an image preprocessing and defect feature extraction module, a big data defect classification and traceability module, a dynamic detection strategy optimization module, a man-machine interaction and remote monitoring module, and a device collaborative control module. The multi-source data acquisition and synchronization module is responsible for multi-source data acquisition and synchronization, and captures multi-angle images of rotating parts in real time through the industrial camera 6, synchronously associates angle signals of a rotary encoder and casting process parameters such as temperature, pressure and the like, constructs a spatiotemporally aligned original data set, and ensures accurate matching of images, motion trajectories and process data.

[0053] The image preprocessing and defect feature extraction module adopts denoising, distortion correction and dynamic light compensation algorithm to eliminate motion blur and environmental interference, and extracts geometric features of a defect area based on edge detection and texture analysis to generate a structured feature vector for subsequent analysis.

[0054] The big data defect classification and traceability module is used to load a pre-trained deep learning model to identify real-time defect types of the feature vector, such as pores, cracks and the like, and simultaneously fuse historical process data to establish an association rule library of defects and process fluctuations, so as to realize rapid positioning of defect sources.

[0055] The dynamic detection strategy optimization module automatically adjusts the sampling frequency of the industrial camera 6 or the rotation speed of the first driving source 8 according to the real-time defect distribution, starts local high-precision re-inspection on the high-occurrence area, and updates the classification model based on the incremental learning mechanism using new samples, thereby improving the adaptability of defect detection.

[0056] The human-computer interaction and remote monitoring module displays real-time detection results, defect heat maps and process alarm information through the Web service embedded in the industrial computer 10, and uploads compressed key data to the cloud quality management system, supports remote report generation and cross-line quality comparison.

[0057] The device cooperative control module drives the first driving source 8, the second driving source 9 and triggers the shooting action of the industrial camera 6 through the PLC and the real-time operating system of the industrial computer 10, ensures the synchronization of mechanical movement and detection process, and automatically triggers the device shutdown protection mechanism when the continuous defect exceeds the standard, forms a "perception-analysis-decision-control" closed loop, and meets the intelligent detection requirements of high precision and low delay.

[0058] The technical scope of the present application is not limited to the content in the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should belong to the protection scope of the present application.
