Research on the application of crimping test scheme based on 3σ criterion and image recognition technology
More and more high-speed connectors are used and the pins are developing in the di-rection of thin,short and soft,which requires for the crimping process of increasingly-high.However,the lack of effective control methods leads to the leakage of faults to the whole ma-chine even to the out-field,the impact is poor.This paper proposes an intelligent control scheme based on the combination of 3σ criterion and image recognition technology.Based on the process characteristics of the stroke curve,the method of pixel variance of image similarity is used to de-tect the abnormal crimping problem,and the 3σ criterion is used to identify and control the process parameters,so as to solve the problems that the crimping quality control rely on person-nel judgments,the kneeling pins and improper crimping cannot be identified.
