A convolution neural network model based on improved YOLOX-S is proposed for metal surface defect image detection. The model changed the structure of the unit module and introduced the attention mechanism module based on the original YOLOX-S model, which optimized the model parameters and improved bounding box position regression loss function and confidence loss function, and then the image detection model of common defects on the metal surface was constructed and realized. The results showed that the loss of improved YOLOX-S model could converge faster, the model with bounding box position regression loss function and attention mechanism added, its mAP increased from 94.23% to 96.14%, and the accuracy improvement effect is the best, while only a small amount of reasoning time is increased. Compared with the YOLOX-S model and the model with different improved methods, it is shown that the improved model based on bounding box position regression loss function and attention mechanism has the best comprehensive recognition effect, which can meet the require-ments of metal surface defect image detection and reduce the outflow of defective products in the production process of metal parts.","PeriodicalId":30222,"journal":{"name":"Journal of Mechanical Engineering and Technology","volume":"193 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77299476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It’s required that the magnetic flux leakage should be as small as possible and air gap magnetic flux should be as large as possible. At present, the general method of increasing the air gap magnetic flux is to increase the ampere-turns of the excitation coil, but the magnetic flux leakage will increase synchronously. The magnetic flux leakage can be reduced by adding a degaussing coil, but it is inconvenient in the design, manufacture and use, and even generates larger stray magnetic fields in some locations. According to the use experience, appropriately reducing the ampere-turns ratio of upper and lower excitation coil can effectively reduce the magnetic flux leakage. Aiming at this phenomenon, it’s simulated that the influence of different upper and lower excitation ampere-turns ratio on air gap flux and magnetic flux leakage when the when the number of ampere-turns remains unchanged. In this paper, con-sidering the air gap magnetic field and the surface magnetic flux leakage, a new method of balanc-ing the air gap flux and the surface leakage is established.","PeriodicalId":30222,"journal":{"name":"Journal of Mechanical Engineering and Technology","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87636102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
