Automatic riveting device suitable for satellite disc type conductive slip ring ultra-thin reed

Abstract

The invention relates to an automatic riveting device suitable for a satellite disc type conductive slip ring ultra-thin reed. The device comprises a riveting machine, a riveting head, a riveting fixed clamping tool, a precise driving platform, a sensor, a control system and the like. A rivet, the reed and a printed brush plate are accurately positioned through the riveting fixed clamping tool; the riveting machine is controlled by the control system, the riveting head is tightly absorbed by means of magnetic force, and the riveting head is pressed to a certain position through high-speed rotation; the sensor is used for feeding back riveting force to the control system in real time to finally achieve riveting of a fixed force value; after one point is riveted, the control system is used for controlling the precise driving platform to accurately move to a next riveting point, and the operation is repeated, so as to realize automatic riveting of the reed. According to the automatic riveting device in the invention, positioning and fastening of the reed are realized, through force feedback control, the pressing quality consistency of the riveting points is guaranteed to be good, andthe reliability is guaranteed to be high; and through the precise driving platform, automatic riveting of a group of reeds is realized, and the product quality precision and efficiency are improved.

Description

technical field [0001] The invention relates to an automatic riveting device. Background technique [0002] The disc-type conductive slip ring is mainly used to transmit electric power and signals between the relatively rotating solar panels and the star, and it is one of the few single-point failure links in the entire star. Disc slip ring is composed of manifold, brush assembly, end cover, bearing, combined bracket and other parts. The technical principle is: the wires of the rotating part of the mechanism are connected to the wires of the busbar, and the electrical conduction is realized through the contacts of the busbar and the brush assembly, and the wires connected to the brush assembly transmit power and electrical signals to the static part of the mechanism. The entire transmission path is wire → confluence plate → brush assembly → wire, which realizes the transmission of electrical signals between two relative rotating mechanisms. [0003] The brush assembly is o...

AI Technical Summary

Problems solved by technology

For the riveting of ultra-thin reeds, it is very easy to cause local deformation of the reeds, or excessive pressure will cause cracks on the printed brush board

At the same time, the positioning accuracy of the same group of reeds is extremely high. Only by single-point riveting, it is easy to cause uneven spacing between the reeds, and it is impossible to achieve reliable contact between the front contacts of the reeds and the bus plate, which affects the stable transmission of electrical properties.
