Laser thickness gauge calibration device and calibration method

The invention relates to the technical field of battery production, and particularly discloses a laser thickness gauge calibration device and calibration method. According to the laser thickness gaugecalibration device provided by the invention, a plurality of tungsten steel sheets with different thicknesses can be placed on the laser thickness gauge calibration device for thickness data acquisition, the detection efficiency is improved, the tungsten steel sheets are used as standard parts to replace pole pieces, the detection precision is high, the tungsten steel sheets can be repeatedly used, and the detection cost is reduced. According to the laser thickness gauge calibration method, the tungsten steel sheet is used as a standard part to replace a pole piece, the thickness of the tungsten steel sheet is known, manual measurement of the thickness of the tungsten steel sheet is not needed, and measurement precision is improved. The tungsten steel sheet replaces a pole piece, cuttingis not needed in the calib
