Description

Technical Field

[0001] The invention relates to the technical field of cable stripping, and in particular to a coaxial cable stripping and welding integrated device and method. Background Art

[0002] At present, in the power communication transmission system, many important services such as dispatching automation and line protection are remotely transmitted based on 2M coaxial cable networking. The application of 2M coaxial cable connectors in substations has basically achieved full coverage. Whether it is the new construction, renovation and expansion of substations or the daily operation and maintenance of equipment, 2M coaxial cable connectors are indispensable and important components in the communication network system. With the in-depth construction of the ubiquitous power Internet of Things, new and higher requirements have been put forward for the reliability, real-time, stability and accuracy of the communication network system. The quality of the production of 2M coaxial cable connectors determines the communication quality of the power dispatching data network. Due to the large workload and complicated process of the traditional production of 2M coaxial cable connectors, coupled with the different skill levels of technicians, there is a general phenomenon of long working hours and low work efficiency for technicians.

[0003] The stripping process of 2M communication coaxial cable is the key technology in production. It is a multi-layer cable with a shielded mesh, including an outer insulation layer, a metal mesh shielding layer and an inner insulation layer, and the conductor is in the innermost layer of the cable. At the same time, in the process of cable stripping, certain process requirements must be followed. Therefore, in the automatic cable welding equipment, the automatic stripping mechanism of multi-layer cables requires a reasonable and feasible technical solution to meet the application requirements.

[0004] The traditional wire stripping method uses a knife or a wire stripping tool. The tool needs to be replaced according to each stripping process and the tool holder needs to be replaced according to the size of the cable. In addition, the technical level of the personnel is different and the workload is heavy. There is a risk of unstable stripping quality and easy short circuit, which ultimately causes communication service interruption. Summary of the invention
