Detailed Description

Referring to fig. 1, 2 and 3, the present invention includes a polygon prism 1, a light source 2 and an industrial camera 3;

the polygonal prism 1 is composed of a prism seat 11 and reflectors 12, the prism seat 11 is a rectangular body, octagonal holes are formed in the rectangular body along the axis, a planar reflector seat is arranged on each side of each octagon, the included angle between the plane where the reflector seat is located and the axis is 45 degrees, eight reflectors 12 are respectively attached to each octagonal reflector seat, the light source 2 is a cylindrical part, and illuminating lamps 21 are uniformly distributed on the cylindrical inner wall of the light source 2 along the circumference; the multi-face prism 1, the light source 2 and the industrial camera 3 are sequentially arranged along the axis of the prism seat 11.

The embodiment of the utility model provides a

In the process of assembling the aerospace electrical equipment, a multi-core wire is required to penetrate into a barrel-shaped terminal frequently, so that the multi-core wire can be used for assembling the electrical equipment, in order to ensure the quality of the wire, the multi-core wire penetrating into the terminal is required to be detected, whether individual wire cores of the multi-core wire penetrate into the terminal is checked, the multi-core wire is generally called wire leakage, and the phenomenon that the wire assembled by an upper assembly line is absolutely not allowed to have the wire leakage exists.

The embodiment of the utility model provides a be used for penetrating the terminal of barrel form to the multicore wire after, carry out the detection of leaking silk.

The specific detection process is as follows,

referring to fig. 1, 2 and 4, a multi-core wire penetrating through a terminal is placed in a prism base 11 along an axis of the prism base 11, a joint of the terminal and a wire core in this embodiment is a collection point of a detected product, and the collection point is located in an effective range captured by a reflector 12, eight reflectors 12 distributed in an octagonal shape on the prism base 11 are respectively collected from the collection points in eight directions around the terminal and the wire core, because an included angle of 45 degrees is formed between a plane where each reflector 12 is located and the axis, information of the collection point on the detected product is incident into a point B of the reflector 12 along the normal direction of the axis, and is reflected out along the direction a of the axis by the point B of the eight reflectors 12 arranged at the included angle of 45 degrees.
