Traditional manual wire cutting relies on the experience of operators for measurement and cutting, which is not only inefficient, but also has large length error, and it is difficult to ensure the consistency and accuracy of the wire. For example, in the power line construction, manual wire cutting error may cause non-standard connection of the line, which has safety hazards; when laying communication optical cable, length deviation will affect the fusion quality and reduce the signal transmission stability. Although some existing mechanical wire cutting devices realize a certain automation, they lack precise length measurement and control function, cannot adapt to the differences in different wire characteristics, and the wire laying process is prone to slipping and jamming, affecting the wire cutting efficiency and wire quality. In addition, the existing equipment has poor cutting mechanism or cutting quality, or complex structure and is difficult to maintain, and most of them cannot realize the full-process automation of wire laying, measurement and cutting, and it is difficult to meet the modern industrial production needs.
