Connecting element inspecting method and connecting element inspecting device
First Claim
1. A connecting element inspecting method for inspecting a connecting element having i) a connecting surface to face a connector to be paired with the connecting element, ii) a plurality of terminal containing holes opening to said connecting surface, and iii) terminals respectively inserted into predetermined terminal containing holes in a predetermined direction of insertion and contained therein, comprising the steps of:
- inputting image data of said connecting surface obtained using light reflected in a direction intersecting said predetermined direction of insertion from said connecting surface;
setting an image region to be inspected in relation to a predetermined terminal containing hole to be inspected on the basis of said image data;
calculating a percentage of the area of a portion occupied by the terminal in said image region to be inspected; and
judging whether said connecting element is accepted or rejected in relation to said predetermined terminal containing hole to be inspected depending on whether or not said percentage satisfies predetermined judgment conditions which judgment conditions include a rejection determination when a terminal is only partially inserted within said predetermined terminal containing hole.

Abstract
The connecting element inspecting method inspects a connector having a connecting surface to another connector paired with the connecting element and a plurality of terminal containing holes opening to the connecting surface for respectively containing terminals. The connecting surface is irradiated by light entering the terminal containing holes. The connecting surface is imaged obliquely from a television camera. The percentage of the area of a portion occupied by the terminal in an image region associated with the terminal containing hole to be inspected is found. It is judged whether or not the terminal is properly mounted in the terminal containing hole to be inspected on the basis of the found percentage of the area. Consequently, it is judged whether the connector is accepted or rejected.

19. A connecting element inspecting device for inspecting a connecting element having i) a connecting surface to face a connector to be paired with the connecting element, ii) terminal containing holes opening to the connecting surface, and iii) terminals respectively inserted into the predetermined terminal containing holes in a predetermined direction of insertion and contained therein, comprising:
-
light irradiating means for irradiating said connecting surface to said connecting element by parallel light entering the terminal containing holes; imaging means so disposed that light reflected in a direction intersecting said predetermined direction of insertion from said connecting surface can be received for imaging said connecting surface using said reflected light; image region setting means for setting an image region to be inspected in relation to a predetermined terminal containing hole to be inspected on the basis of image data from said imaging means; percentage calculating means for calculating the percentage of the area of a portion occupied by the terminal in said image region to be inspected; and judging means for judging whether said connecting element is accepted or rejected in relation to said predetermined terminal containing hole to be inspected depending on whether or not said percentage satisfies predetermined judgment conditions which judgment conditions include a rejection determination when a terminal is only partially inserted within said predetermined terminal containing hole. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
