  • Coating thickness inspection method and coating thickness inspection device
    Patent number: 10001366
    Abstract: A coating thickness inspection device (20) is provided with: a displacement gauge (25); a position calculation unit (28a); and a determination unit (28b). The displacement gauge (25) measures the external shape of a rectangular wire (30) across the lengthwise direction thereof (external shape measurement step). The position calculation unit (28a) determines the position of a rectangular conductor (31) within the rectangular wire (30) across the lengthwise direction of the rectangular wire (30) (position calculation step). The determination unit (28b) determines whether the thickness across the peripheral direction of a coating section (32) as calculated on the basis of the results obtained by the displacement gauge (25) and the position calculation unit (28a) satisfies a standard thickness across the lengthwise direction of the rectangular wire (30) (determination step).
