Rotary pay-off type polarized grid winding device

Abstract

The invention relates to a rotary paying-off polarization gridding winding device, and belongs to the field of the aerospace technology. The rotary paying-off polarization gridding winding device is mainly composed of a base, a ball screw nut pair, a linear rolling guide rail pair, a rotary disc bearing and a paying-off device, wherein the base plays a role in supporting and fixation, the ball screw nut pair moves along the linear rolling guide rail pair under the driving of a servo motor to jointly form feeding movement in the X direction, the rotary disc bearing rotates under the driving of the servo motor, and the paying-off device finishes playing-off motions. The rotary paying-off polarization gridding winding device is simple in structure, low in cost and high in efficiency, and has the advantages of being simple in structure, novel in concept, low in cost and high in efficiency. The feeding system combining ball screws and linear rolling guide rails effectively avoids the phenomenon of low-speed creeping, and improves movement accuracy and stability. A mechanical device replaces a traditional manual winding method, not only improves production efficiency, but also effectively guarantees the quality of products. The rotary paying-off polarization gridding winding device is high in practicability.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a rotating and unwrapping polarized grid winding device, which is suitable for producing polarized grids used in cosmic background detectors. Background technique [0002] Microwave radiometer is a microwave remote sensor that passively receives radiation signals from objects. It is playing an important role in atmospheric water vapor detection, ocean wind field detection, land resource detection, military detection and daily life. The microwave radiometer first needs to measure the two parameters of vertically polarized radiation brightness and horizontally polarized radiation brightness temperature of the target microwave radiation, and then data inversion can be performed. In order to obtain the brightness temperature of vertically and horizontally polarized radiation, a polarizer has to be used to separate the polarization of the target microwave radiation. In my country'...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the polarized wire grids used in my country are imported polarized wire grids, which are expensive; while the domestic processing method of wire grids is mainly manual winding, with low precision and long production cycle

At the same time, winding machines at home and abroad are mainly used in textile wiring, electronic components, wire cutting, etc., the control variables are relatively single, and the accuracy is relatively low
