Vertical polarization wire grid production device

Abstract

The invention relates to a vertical polarization wire grid production device and belongs to the microwave radiation and microwave remote sensing field. The vertical polarization wire grid production device is composed of a base, a rotary feeding mechanism, a guide mechanism, a motor driving system, a position-limiting protection mechanism and a tension stabilization mechanism; the base enables a supporting and fixing effect; a rotating wire frame completes rotational motion under the driving of a servo motor; the tension stabilization mechanism completes a paying-off action when maintaining the tension of lines stable; the ball screw nut pair of the guide mechanism drives the tension stabilization mechanism to move along the guide axis of a linear bearing under the driving of the servo motor, so as to jointly form feeding movement in an X direction. The vertical polarization wire grid production device has advantages of simple structure, low manufacturing cost and high production efficiency. With the vertical polarization wire grid production device adopted, a new path can be provided for the localization of millimeter-wave band polarization line grids, and deficiencies of China in polarization wire grid protection instruments can be compensated.

Description

technical field [0001] The invention relates to the field of microwave radiometer and microwave remote sensing, in particular to a vertical polarized wire grid production device, which is specially used to produce polarization separation of electromagnetic waves, and has the characteristics of wide frequency band and low loss. , millimeter wave, submillimeter wave and far-infrared band widely used polarized wire grid device. 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; microwave radiometer first needs to measure the target Vertically Polarized Radiation Brightness Temperature of Microwave Radiation and horizontally polarized radiation brightness temperature These two parameters can only be used for data inversion; in order to ...

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, domestic and foreign winding The machine is mainly used in textile wiring, electronic components, wire cutting, etc., the control variable is relatively single, and the precision is relatively low; therefore, it is extremely important to develop an automatic winding processing device for polarized wire grids
