COATING THICKNESS INSPECTION METHOD AND COATING THICKNESS INSPECTION DEVICE

摘要

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).

主权项

1. A method for inspecting the thickness of a coating section of a rectangular wire that consists of a rectangular conductor having a narrow and long shape, cross-section of which has a rectangular shape, and a coating section coating the rectangular conductor, the method comprising:
an external shape measurement step for measuring an external shape of the rectangular wire across a lengthwise direction of the rectangular wire; a position calculation step for determining the position of the rectangular conductor within the rectangular wire across the lengthwise direction of the rectangular wire; and a determination step for determining whether the thickness across a peripheral direction of the coating section as calculated on the basis of results obtained by the external shape measurement step and the position calculation step satisfies a standard thickness across the lengthwise direction.
