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.
