Method for detecting tinning amount of tinned plate based on fluorescence spectrophotometer

The invention relates to the field of tin plating amount detection, in particular to a tin plating amount detection method for a tin plate based on a fluorescence spectrometer. The method comprises the following steps: carrying out fluorescence spectrum analysis on a standard tinning amount sample to obtain a standard curve of fluorescence intensity and tinning amount; obtaining a to-be-detected tin plate sample from the to-be-detected tin plate; the to-be-detected tin plate sample comprises at least one to-be-detected area, and placing the to-be-detected area in a detection area of a fluorescence spectrophotometer to obtain a measured value; according to the measured value and the standard curve, the tinning amount of the to-be-measured area is obtained; according to the method, the tinning amount of the strip steel from the edge to 0 mm and the tinning amount of the bright edge defect of the edge of the tinned plate are detected, the requirements of an existing detection method for the tinning amount detect
