[0047] In this embodiment, an appearance inspection module 6 and a defect coding module 7 are provided between the feeding conveying module 5 and the discharging conveying module.

[0048] The defect coding module 7 is located between the discharge conveying module and the appearance inspection module 6. The defect coding module 7 includes a defect conveying line 29 and a coding module.

[0060] At the same time, the detection module also includes multiple groups of inspection fiber optic sensors 23, which are all fixedly installed on the left detection track. The first group of inspection fiber optic sensors 23 is fixedly installed between the plasma surface processor 14 and the detection camera, the second group of inspection fiber optic sensors 23 is installed between the upper detection camera and the lower detection camera, and the third group of inspection fiber optic sensors 23 is installed between the lower detection camera and the front camera 15.

[0061] During operation, inductor winding frames are fed into the feed conveyor module. The speed of the feed conveyor belt can be adjusted by controlling a stepper motor to meet production cycle requirements. The feed conveyor module consists of a left feed track and a right feed track, which are not fixedly connected to each other, allowing for easy adjustment of the spacing to accommodate inductor winding frames of varying widths. Furthermore, in this embodiment, each module is width-adjustable, capable of accommodating inductor winding frames of varying widths.

[0062] The inductor winding frame flows into the upper feed conveyor module, first undergoing a tensile test in the tensile testing module, then undergoing surface treatment in the plasma surface treatment module. This treatment can address the problem of poor adhesion during subsequent powder metallurgy pressing. The material then enters the inspection station for inspection in the appearance inspection module. This module consists of four camera assemblies and one light source assembly. These four cameras photograph the four sides of the copper coils on the inductor winding frame. Fiber optic sensors detect the position of the inductor winding frame, sending signals to different cameras for image inspection.

[0063] The entire inductor winding frame moves along the conveyor line and passes through the inspection station. Under the lighting effect of the light source, the camera component performs mobile photo inspection on the inductor winding frame to detect whether there are any defects in the appearance of the copper ring on the inductor winding frame.

[0064] Fiber optic sensors detect when the inductor winding frame enters the upper and lower visual inspection stations, triggering the upper and lower inspection cameras to take photos. During these inspections, pressure wheels roll the inductor winding frame to ensure a smooth surface for photo inspection. The entire conveyor line is controlled by a servo motor system, enabling precise control of the belt line speed.

[0065] When an inductor winding frame enters the defect inkjet station, if the front section determines it is a good product, it flows directly to the next station via a conveyor belt without requiring inkjet processing. If the inductor winding frame is deemed defective at the front end, the defect fiber optic sensor assembly triggers the inkjet station to inkjet-mark both the top and bottom surfaces of the inductor winding frame. The inkjet station precisely marks both sides of the coils at different locations on the inductor winding frame. A camera detects which copper coil is defective and triggers a signal to inkjet-mark the corresponding inductor winding frame.

[0066] The inductor winding frame enters the discharge conveyor line assembly. If it is judged as a good product by the previous visual inspection, the inductor winding frame flows along the belt conveyor line to the next workstation and flows out from the good product discharge conveyor line.

[0067] If the front-end vision component determines that the inductor winding frame is defective, it needs to be rejected. The blocking cylinder blocks the inductor winding frame, and the defective product discharge track is separated by the defective product drive cylinder. The belt line spacing increases, and the inductor winding frame falls onto the defective product guide plate, then slides into the defective product conveyor belt line, and flows out along the belt line, completing the rejection process. The defective product discharge track is driven by the defective product drive cylinder. In normal status, the cylinder does not move, and the inductor winding frame moves normally with the belt line. When rejection is required, the cylinder drives the defective product discharge track to be pulled out, so that the belt line spacing increases. The inductor winding frame loses its support and falls onto the defective product guide plate below.

[0068] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0069] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
