| description | The invention relates to a coating process method based on wide spectrum monitoring. The method comprises the steps that a workpiece to be coated and a monitoring piece are installed; initializing and loading a coating process; drawing a circumferential spectrum curve and positioning the angle position of the monitoring sheet on the product turntable; automatically executing a coating process program; in the film coating process, spectral energy data of the monitoring piece are collected in real time, and the real thickness of the current film layer is obtained through fitting; calculating the layer change stop judgment time and triggering the layer change stop judgment logic; and after the layer is changed, coating the next film layer until all the film layers in the coating process are completed. According to the technical scheme, the layer changing position can be accurately positioned, the delay defect that layer changing is controlled through a conventional evaluation function method is overcome, the acc |
