Summary:As a core product in daily chemical products, injection pumps are used frequently in life, so the quality control of injection pumps has become a very important aspect for injection pump manufacturers. The purpose of this paper is to study the deep learning-based defect detection method for injection pumps to achieve a fully automated, stable, efficient and easy-to-deploy defect detection system for injection pumps. A CenterNet-based defect detection model is proposed to improve the DLA based on deformable convolution to increase the recognition ability of irregular defects, and a focused loss function is used to solve the problem of uneven positive and negative samples. And the model compression method of channel sparsification and the model quantization method of NCNN are used to optimize the deployment of the model in mobile.
