MQ magnet shooting and wrapping fan blade

Abstract

The invention relates to an MQ magnet shooting and wrapping fan blade. The MQ magnet shooting and wrapping fan blade comprises a fan blade body, an axis is arranged in the center of the fan blade body, a plurality of blades are arranged on the outer wall of the fan blade body, a motor shell is fixed to the inner wall of the fan blade body, and a plurality of MQ magnets arranged around the axis at intervals are arranged on the inner wall of the motor shell and the top, close to the inner wall of the motor shell, of the fan blade body. The outer walls of the MQ magnets are coated with rubber coating layers which are integrated with the top of the motor shell and the fan blade body close to the motor shell or the MQ magnets, and the fan blade body, the blades, the motor shell and the MQ magnets are tightly combined into an integrated structure through injection molding, so that the bonding strength is improved; and the MQ magnets are formed through direct rubber coating, compared with a traditional structure and technology that the MQ magnets are pressed in after glue dispensing, operators and procedures are eliminated, the operation difficulty is lowered, the concentricity of the multiple MQ magnets around the axis after being assembled and combined with the motor shell and the fan blade body is guaranteed, the machining efficiency and the balance degree of the fan blade are remarkably improved, and the requirement for the quality of the fan is met.

Description

technical field [0001] The invention relates to an MQ magnetite-coated fan blade, which belongs to the technical field of fan blade structure. Background technique [0002] The fan is a device that is electrically driven to generate airflow. According to the direction of the wind, it is divided into two types: axial flow and centrifugal. Among them, the axial flow fan is widely used in the cooling environment of electronic devices such as CPU, which directly affects the application of electronic devices. longevity and stability. The fan is mainly composed of a rotor composed of magnets, fan blades and shafts, a stator composed of silicon steel sheets, spools and bearings, and an IC induction magnet control circuit. The circuit controls the conduction of the stator coils to generate internal excitation to make the rotor blades revolve around the axis. Rotating on the support and protection parts such as the outer frame to generate wind force, accelerate especially the flow o...

AI Technical Summary

Problems solved by technology

When the fan blade assembly is formed, glue is dispensed at the installation positions of the magnets on the inner wall of the fan blade main body at intervals around the shaft. Factors such as fluid properties, press-in pressure and other factors can easily cause the magnets to deviate and tilt to varying degrees in the direction of rotation. When driving or installing with the motor assembly outside the shaft center and inside the main body of the fan blade, it will affect the balance of the fan blade and the defective rate. And the difficulty of the operation is high, and the processing efficiency is low
