However, this thickness still does not meet the needs of electronic equipment. With the development of electronic equipment, it is necessary to use ultra-thin fan blades thinner than 0.1mm to make ultra-thin fans
[0003] However, the blades of the fan need to be fixed in a plastic mold one by one, and then molded to obtain a complete fan, which does not meet the production needs

Embodiment 1
[0072] First, put the metal material with a thickness of less than 0.1 mm into the first stamping die, through the first stamping die, the metal material is punched, trimmed, formed, shaped and empty-stepped multiple times in order to form the first end as The connecting part and the second end are folded fan blades. Specifically, the connecting portion of each fan blade includes a hollow cylinder and a connecting hole.
[0073] Then, the connection holes of different fan blades and the hollow cylinder are stamped and combined through the second stamping die, so that the first ends of the fan blades are connected to each other, and the first ring is formed;
[0074] Then, put the fan blade formed with the first ring body into the injection mold, and through injection molding, obtain the first plastic shell wrapped on the first ring body and the second plastic shell wrapped on the hem body, get a fan.
Embodiment 2
[0076] First, put the metal material with a thickness of less than 0.1mm into the first stamping die, through the first stamping die, the metal material is punched, trimmed, formed, shaped and empty-stepped multiple times in order to form the second end as Folded fan blades. Wherein, the first stamping die is a continuous stamping die.
[0077] Then, the metal material is put into the second stamping die, and the metal material is stamped through the second stamping die to obtain the annular connecting seat.
[0078] Then, the annular connecting seat is connected to the welding base, and the fan blades formed by the first stamping die are transferred to the welding base through the material belt, so that a preset number of fan blades are spot welded on the annular connecting seat. Specifically, the welding base can be connected with a stepping motor, and rotated by the stepping motor, so that the fan blades are welded at a designated position of the annular connecting seat, a...

Abstract
The invention discloses a fan, electronic equipment and a manufacturing method of the fan. The fan comprises a plurality of fan blades and a first plastic shell, wherein each fan blade comprises a first end and a second end opposite to the first end; the first ends of the fan blades are annularly arranged to form a first ring body; and the first plastic shell wraps the first ring body.
Description
technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a fan, electronic equipment and a method for making the fan. Background technique [0002] The heat dissipation fans of electronic equipment are usually made of all plastics. However, due to the limitation of the plastic manufacturing process, the thickness of the plastic blades of the current heat dissipation fans has reached 0.1mm. However, this thickness still does not meet the requirements of electronic equipment. With the development of electronic equipment, it is necessary to use ultra-thin fan blades thinner than 0.1 mm to make an ultra-thin fan. [0003] However, the fan blades of the fan need to be fixed one by one in a plastic mold, and then molded to obtain a complete fan, which does not meet the production needs. Contents of the invention [0004] Embodiments of the present application provide a fan, an electronic device, and a manufacturing ...
