Abstract

The invention discloses a method and system for controlling nitrogen filling of a cable foam layer. During the nitrogen filling process of cable core wire processing, the detection image of the core wire during nitrogen filling is obtained by X-ray flaw detection equipment in real time; Get the foam layer image of the cable in the detection image, calculate the uniformity of the foam layer image during nitrogen filling, and adjust the nitrogen filling speed according to the uniformity, and can intelligently control the nitrogen filling speed and air pressure to make the thickness uniformity of the foam layer Moderate, resulting in stable cable capacitance, ensuring the transmission bandwidth, transmission rate, and data transmission stability of the produced cables to meet the technical requirements for high-speed transmission and information exchange, so that the produced cables have uniform transmission impedance.

Description

technical field [0001] The disclosure belongs to the technical field of wire and cable and cable technology, and in particular relates to a method and system for controlling nitrogen filling of a cable foam layer. Background technique [0002] During the processing of the core wire of the twisted pair, it is generally necessary to fill the cladding layer of the core wire with an inert gas, such as nitrogen, for foaming to form a foam layer. By using chemically foamed polyolefin material in extrusion The heat and pressure foaming extrusion molding in the machine screw chamber realizes the molding of the foam insulating core wire, but the uneven nitrogen filling speed and insufficient air pressure will cause the actual thickness of the foam layer to be different, resulting in unstable capacitance changes , so that the final cable transmission bandwidth, transmission rate, data transmission stability, etc. are difficult to meet the technical requirements of high-speed transmiss...
