A treatment method for the external cable shielding layer of a conductive slip ring for a three-axis precision turntable

Abstract

The invention provides a method for processing the external cable shielding layer of a conductive slip ring for a three-axis precision turntable, including: arranging, turning over, and reversing the wire mesh shielding layer; interconnecting signal cables of the same level; After the wire mesh shield and solder joints are finished. The method provided by the invention can interconnect the shielding layers of different cables of the same level of signals to form an overall shielding effect, realize the processing position of the shielding layer of a single cable is thin and uniform, the solder joints are small, and completely avoid the metal wire of the shielding layer from piercing the core resulting in a short circuit. This cable shielding layer processing method is applied to the three-axis precision turntable, and it is convenient to thread the wires in the narrow inner cavity of the turntable, which solves the problem of shielding and signal communication caused by the shielding layer during the processing process. Point grounding eliminates the coupling interference caused by the complex electromagnetic environment in the cavity of the turntable, improves the anti-interference ability of the overall line of the equipment, and improves the reliability of the shielding process.

Description

technical field [0001] The invention belongs to the technical field of cable shielding treatment, and in particular relates to a treatment method for an external cable shielding layer of a conductive slip ring for a three-axis precision turntable. Background technique [0002] The conductive slip ring is placed inside the rotating shaft of the precision turntable, and its lines are laid in the cavity of the turntable. About 500 cables transmit different signals, including strong current, weak current, sensors, encoders, user signals, etc. The power motor is installed, which leads to the complex electromagnetic environment inside the precision turntable, and the signal is easily disturbed during the transmission process. All adopt the design method of shielded cable, and the shielding layer of the shielded cable is a wire mesh layer to eliminate electromagnetic compatibility problems caused by electromagnetic radiation and conduction. However, due to the complexity of the el...
