A piezoelectric thin film testing mechanism

Abstract

This utility model discloses a piezoelectric thin film testing mechanism, relating to the field of piezoelectric thin film technology. It includes a housing, on one side wall of which a linear motion module is horizontally mounted. A column is vertically mounted at the output end of the linear motion module. A mounting plate is horizontally mounted on the upper end of the column, and an electric telescopic rod is vertically mounted on the mounting plate. A fixing frame is horizontally mounted at the output end of the electric telescopic rod. A rotating shaft is horizontally arranged inside the fixing frame, and a pressing roller is mounted on the side wall of the rotating shaft inside the fixing frame. A limit assembly is provided on the housing, and a rotation assembly is provided on the fixing frame. This utility model utilizes gears and racks to enable the pressing roller to rotate, preventing it from rotating out of time and causing the piezoelectric thin film to move. Several elastic telescopic rods limit the piezoelectric thin film of different widths, preventing the piezoelectric thin film from shifting during testing.
