It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a defect detection system for a copper-plated welding wire according to an embodiment of the present application. The system for detecting defects of the copper-plated welding wire can comprise:
the device comprises a camera device 1, an infrared light source 2, a fixed bracket 3 and a processor;
the camera device 1 and the infrared light source 2 are arranged above the silk disc 4 through the fixed support 3; the wire disc 4 is used for winding copper-plated welding wires;
the camera device 1 is used for shooting a coiling image of a copper-plated welding wire coiling in an irradiation environment of the infrared light source 2;
the processor is connected with the camera device 1 and is used for collecting the winding disc images shot by the camera device 1 so as to identify the black and green wires in the copper-plated welding wires according to the winding disc images;
the camera device 1 and the infrared light source 2 are arranged above the silk disc 4 through the fixed support 3.
Specifically, in the manufacturing process of the copper-plated welding wire, the copper-plated welding wire needs to be wound on the wire reel 4 through a wire winding machine, so that the copper-plated welding wire is convenient to split, transport and sell. The defect of black and dark wires can be generated on the copper-plated welding wire due to the manufacturing process, and the product quality of the copper-plated welding wire is seriously influenced. Therefore, in the actual production, the defect of the black and green wires in the copper-plated welding wire needs to be found in time by manual observation and detection in the process of winding the copper-plated welding wire onto the wire coil 4 to form a finished product.
However, the diameter of the copper-plated welding wire per se is generally not more than 2mm, so that the copper-plated welding wire is very fine when being wound on the wire coil 4, which brings difficulty to observation and detection of the black and green wires by workers; in addition, even if a section of the blue and black wire exists in the copper-plated welding wire and the wire disc 4 is in a rotating state, the section of the blue and black wire is in the rotating state, and further, the condition of the blue and black wire is difficult to accurately detect by workers.
Therefore, in the embodiment, by utilizing the characteristics that the surface of the normal copper-plated welding wire is reddish and the surface of the black wire is blackish, and the normal copper-plated welding wire has strong infrared light reflection capability and weak black wire reflection capability, the infrared light source 2 is adopted to provide an infrared illumination environment, so that the normal copper-plated welding wire is brighter and has more obvious contrast relative to the black wire in the infrared illumination environment, and the significance of the black wire in the copper-plated welding wire is further enhanced; furthermore, considering the fact that the blue and black wires need to be checked in the rotating process of the wire disc 4, the camera device 1 is further arranged in a matched mode, the winding disc image of the copper-plated welding wire is shot through the camera device 1 to replace direct observation of naked eyes, and the difficulty and the accuracy of the blue and black wire checking are reduced; after the image of the winding disk is shot by the camera device 1, the image can be timely recorded and uploaded by the processor, so that a worker can observe and detect the winding disk.

Because the light intensity generated in the space is not uniform for the point light source and the line light source, the light intensity reflected by the surface of the copper-plated welding wire is also not uniform, and if the partially reflected light is too strong, the light of the black and green wires is covered by the light strongly reflected by the periphery. This application adopts the area source as the light source that provides infrared illumination for infrared illumination in the whole space environment is more even, and then makes the luminance on copper facing welding wire surface also comparatively even, improves the rate of accuracy that blue or green black silk detected.
In another optional embodiment of the present application, the method may further include:
the image pickup device 1 and the infrared light source 2 are provided with a protective case 5.

When the image pickup device 1 picks up the reel image, it is necessary to set an appropriate pick-up angle and an appropriate infrared illumination angle according to the size of the actual wire reel 4 and the thickness specification of the wire reel 4.
Therefore, the camera device 1 and the infrared light source 2 are rotatably mounted on the fixing support 3, so that in practical application, a worker can adjust the optical axis direction of the camera device 1 and the irradiation direction of the infrared light source 2 according to actual needs, and the optical axis direction of the camera device 1 determines the shooting angle of the camera device 1.
The rotation of the camera device 1 and the infrared light source 2 can be manually adjusted by a worker or automatically adjusted by a driving motor.
Specifically, a driving motor can be arranged on the fixed support 3, the driving motor is controlled by the processor, and the worker can output an adjusting instruction through the processor according to actual needs to set the adjusting angle of the driving motor for driving the camera device 1 and the infrared light source 2. The processor automatically controls the driving motor to adjust the camera device 1 and the infrared light source 2 according to the set angle.
