Crimping determination device, crimping determination method, crimping determination program, wire harness processing device, and wire harness processing method

A crimping determination method for determining a quality of a crimped state of a wire harness in which a crimping terminal is crimped to an electric wire, the method comprising:

• a dropping process of dropping a test solution to the wire harness, the wire harness including a crimped portion in which the electric wire is crimped by the crimping terminal, a first electric wire portion in which the electric wire is exposed on a distal end side with respect to the crimped portion, and a second electric wire portion in which the electric wire is exposed on a proximal end side with respect to the crimped portion, the test solution being dropped to either one of the first electric wire portion and the second electric wire portion in the dropping process;
• a pre-dropping image acquisition process of acquiring an image including the other one of the first electric wire portion and the second electric wire portion before the dropping process,
• in the pre-dropping image acquisition process, a first image before the test solution is dropped being acquired,
• in the post-dropping image acquisition process, a second image after the test solution is dropped being acquired, and
• a determination process, an outflow rate of the test solution in the other one of the first electric wire portion and the second electric wire portion being obtained based on the first image and the second image, and the quality of the crimped state of the crimped portion being determined based on the outflow rate.

A non-transitory storage medium in which a crimping determination program for determining a quality of a crimped state of a wire harness in which a crimping terminal is crimped to an electric wire, the program comprising:

• a dropping process of dropping a test solution to the wire harness, the wire harness including a crimped portion in which the electric wire is crimped by the crimping terminal, a first electric wire portion in which the electric wire is exposed on a distal end side with respect to the crimped portion, and a second electric wire portion in which the electric wire is exposed on a proximal end side with respect to the crimped portion, the test solution being dropped to either one of the first electric wire portion and the second electric wire portion in the dropping process;
• a post-dropping image acquisition process of acquiring an image including the other one of the first electric wire portion and the second electric wire portion after the dropping process;
• and
• a determination process of obtaining an outflow rate of the test solution in the other one of the first electric wire portion and the second electric wire portion based on the first image and the second image, and determines the quality of the crimped state of the crimped portion based on the outflow rate.
