The process of welding fan processing method is as follows:

I. Surface mount process of welding fan processing

Assembly frame and silicon steel sheet->winding->brush solder paste->paste electronic parts->reflow soldering->appearance inspection (repair soldering)->coil and PCB assembly->enameled wire welding->appearance inspection-assembly test.

II. Welding fan processing plug-in program

Lead assembly frame and silicon steel sheet->winding->insert electronic parts->pass soldering furnace->cut edge->pass wave soldering->appearance inspection (repair soldering)->coil and PCB assembly->enameled wire welding->appearance inspection-assembly test.

III. Processing flow of fan blade assembly of welding fan processing

Magnetic input->magnetization->compressor blade->balance.

IV. Assembly flow of fan processing of welding fan processing

Welding lead->assembly->pressing->assembly copper->oil ring on fan blade->set fan blade->front end test->oil ring retaining spring->rear end test->labeling->appearance inspection->packaging,

The present invention relates to the field of mechanical industry technology, and more specifically, to a processing method of a fan, and a fan prepared by the above processing method.

[Background Technology]

The fan is a commonly used heat sink in electronic equipment. It includes a disk, a reinforcement ring and multiple blades. The root of the blade is fixedly connected to the disk, and each blade is distributed along the circumference of the disk. The reinforcement ring is located at the periphery of the disk and is fixedly connected to each blade.

At present, the blades, reinforcement ring and plate of the fan are all made of plastic materials, and the three are integrally formed by injection molding. Among them, in order to ensure sufficient strength, the thickness of the blade cannot be set very small, resulting in low air volume and air pressure of the fan and poor heat dissipation performance.

In summary, how to ensure that the fan blades have sufficient strength, reduce the thickness of the fan blades, and improve the heat dissipation performance of the fan is an urgent problem that technicians in this field need to solve.
