[0061] During specific operation, the inductor winding frame flows into the feeding conveyor module, and the speed of the feeding conveyor belt can be adjusted by controlling the stepper motor to meet the production rhythm requirements. The feeding conveyor module consists of a left feeding track and a right feeding track, which are not fixedly connected to each other, so that the spacing can be adjusted to meet the needs of inductor winding frames of different widths. Moreover, in this embodiment, each module can be adjusted in width to meet the needs of inductor winding frames of different widths.

[0062] The inductor winding frame flows in from the upper feeding conveying module, first undergoes a tensile test through the tensile test module, and then undergoes surface treatment through the plasma surface processor, which can solve the problem of poor adhesion of the powder metallurgy pressing molding in the later stage, and then enters the inspection station for inspection through the appearance inspection module. The appearance inspection module has a total of 4 sets of camera components and a set of light source components. Through the 4 sets of cameras, the 4 sides of the copper coil on the inductor winding frame are photographed and inspected. The optical fiber sensor detects the position of the inductor winding frame and sends a signal to different cameras for photo inspection.

[0063] The entire set of inductor winding frames moves with 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 frames to detect whether there are any defects in the appearance of the copper ring on the inductor winding frames.

[0064] The optical fiber sensor detects the inductor winding frame entering the upper and lower visual inspection stations, triggering the upper and lower inspection cameras to take photos. At the upper and lower visual inspection stations, the inductor winding frame is rolled and shaped by the pressing wheel to ensure that the surface of the inductor winding frame is flat when it is photographed and inspected. The entire conveyor line is controlled by a servo motor system, which can accurately control the belt line speed.

[0065] When the inductor winding frame enters the defective inkjet station, if the front section is judged as a good product, the inductor winding frame flows directly out of the next station through the belt conveyor line without inkjet processing. When the inductor winding frame is judged as a defective product at the front end, the defective optical fiber sensor component triggers the inkjet terminal to inkjet the upper and lower surfaces of the inductor winding frame. The inkjet needs to accurately mark both sides of the coils at different positions of the inductor winding frame. The camera detects and determines which copper coil is defective, triggers the inkjet terminal signal, and inkjet marks 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 into the next workstation along the belt conveyor line and flows out from the good product discharge conveyor line.

[0067] If the front-end visual component determines that the inductor winding frame is a defective product, it needs to be rejected. The blocking cylinder blocks the inductor winding frame. Under the action of the defective product driving cylinder, the defective product discharge track is separated, the belt line spacing is increased, and the inductor winding frame falls onto the defective product guide plate, then slides into the defective product conveying belt line, and flows out with the belt line to complete the rejection process. The defective product discharge track is driven by the defective product driving 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 becomes larger, and the inductor winding frame loses support and falls onto the defective product guide plate below.

[0068] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
