Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to a cutting surface detection light source. Background Art

[0002] At present, point light sources are usually used to detect defects on the cutting surface of wires or cables. Traditional dome light sources are used to illuminate the wires to be inspected. The illumination of this light source is usually diffusely reflected by the inner side of the dome light source, so that the light hits the wires to be inspected, so as to illuminate the sides and cutting surface of the wires to be inspected, and then the image on the cutting surface is obtained through the camera, and the defects on the cutting surface are analyzed.

[0003] However, the current traditional dome light source usually uses a single irradiation direction light board, and the light from the light board is diffusely reflected to the top surface of the dome shell to illuminate the detected wire. Since the cutting surface is located at the end of the wire, the diffusely reflected light is not enough to illuminate all parts of the cutting surface during irradiation, a shadow area will appear on the cut surface being detected, resulting in unclear images obtained by the camera, which affects the detection results.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] For the convenience of describing the first direction and the second direction in the embodiment of the present application, the first direction is the up-down direction in the drawings, and the second direction is the left-right direction in the drawings. The x-axis arrow direction is referred to as the "right" direction in the following text, and the y-axis arrow direction is referred to as the "up" direction in the following text, which is not limited to the actual application of the present application.

[0030] Please refer to Figure 1-3As shown, the present embodiment provides a cutting surface detection light source 100, which includes: a shell 110, including a reflective surface 111, the reflective surface 111 is arranged on the inner side of the shell 110, and the shell 110 has an installation position 11b for placing the object to be detected; further, the cutting surface detection light source 100 also includes a first light-emitting board 121 and a second light-emitting board 122; wherein the first light-emitting board 121 is installed on the shell 110, and the second light-emitting board 122 is installed on the shell 110, the first light-emitting board 121 irradiates toward the reflective surface 111 along a first direction and diffusely reflects through the reflective surface 111 to irradiate toward the installation position 11b; the second light-emitting board 122 irradiates toward the installation position 11b along a second direction. It can be understood that in this embodiment, the light projected by the first light-emitting board 121 is reflected in all directions by the reflective surface 111 of the shell 110. Since the surface of the reflective surface 111 is uneven, diffuse reflection of the light can be achieved, so that the light is evenly dispersed in all directions; however, in this embodiment, the light after diffuse reflection by the reflective surface 111 is irradiated onto the object to be detected at the installation position 11b, and hits various parts of the object to be detected; in this embodiment, the object to be detected is usually a wire such as a wire or a cable, and when the cut surface of such an object to be detected is detected, since the direction of the cut surface is different from the direction of the wire body, a part of the light from the first light-emitting board 121 is irradiated onto the cut surface of the object to be detected after diffuse reflection, and the cut surface is illuminated, but only this part of the light after diffuse reflection is irradiated The light reaching the cutting surface cannot illuminate all parts of the cutting surface, because the cutting surface will tilt in the horizontal or vertical direction during the cutting process, and the light after diffuse reflection will be affected by the inclination angle of the cutting surface and cannot illuminate the entire area of ​​the cutting surface, so that shadows are generated in some areas; it can be understood that the second light-emitting panel 122 emits light along the second direction toward the side of the mounting position 11b, so that the light of the second light-emitting panel 122 can directly illuminate the side of the object to be inspected, that is, illuminate the cutting surface of the object to be inspected, and fill in the light on the cutting surface, so that all areas of the cutting surface are illuminated, so that the camera can obtain a clear image when taking pictures of the cutting surface, so as to more easily detect defects on the cutting surface, that is, detect whether the surface of the cutting surface has uneven defects.
