METHOD AND APPARATUS FOR EVALUATING STATE OF APPLICATION

摘要

PROBLEM TO BE SOLVED: To accurately and appropriately evaluate the state of application for every divided section among a plurality of divided sections acquired by longitudinally dividing an applied region in the case of evaluating the state of application of an applied film formed in a band shape by continuously applying an applied material to the band-shaped applied region of an object to be applied in consideration of changes in the direction of a three-dimensional curved surface in the case that the applied film is formed in a three-dimensional curve and in consideration of changes in conditions of application in the case that conditions of application for the application of the applied material have changed.

SOLUTION: The applied region 9 is longitudinally divided to set the plurality of divided sections, and the applied region 9 is divided in lateral directions to set a plurality of divided lanes continuously extending in longitudinal directions of the applied region 9. A detection head 16 for irradiating the applied region 9 with spot light 20a and receiving its reflected light is made to scan along a primer applied film 5. Light reception data of light received by the detection head 16 is processed for every one of the plurality of divided lanes for each of the plurality of divided sections to evaluate the state of application on the basis of the light reception data.
