Embodiment Construction

[0044] see Image 6 , showing a method for balancing a rotor 61 of a DC fan 60, the rotor 61 includes a rotor body 62 and a plurality of fan blades 63, the method includes the steps of: detecting a portion 64 with excess weight of the rotor 61 of the fan 60 , and use a laser beam to remove the part with excess weight, and perform the work of removing excess weight within a time, so as to achieve the effect of balancing the rotor 60, that is to say, the new technical feature of the present invention is to use laser to remove excess weight The resulting imbalance of the fan 60.

[0045]The method also includes calculating a rotation angle of the portion with excess weight 64 to receive the irradiation of the laser beam before removing the portion with excess weight 64 . Here, when calculating the angle of rotation with excess weight other than 64, for example: based on the calculation of a star point (Star Mark) 65 that each fan has, it is calculated that the portion 64 with ex...

Abstract

The invention discloses a balancing method and a processing method of a fan. The balancing method comprises the following steps of: detecting an excessive weight part of a rotor of the fan; removing the excessive weight part by utilizing a laser beam, and executing an excessive weight removal operation in one period. The method achieves the effect of balancing the rotor.

Description

technical field [0001] The invention relates to a balancing method and a processing device for a fan, in particular to a balancing method and a processing device for a fan which uses a laser to remove excess weight. Background technique [0002] The materials used in general computer fans can be roughly divided into two types: metal and polybutylene terephthalate (PBT). , in order to reduce unnecessary vibration, such as "reduce-to-balance" balance method (Reduce-to-Balance) to deal with a defective product, it is necessary to reduce the weight of the overweight part of the rotor. However, in the process of achieving balance by reducing weight, when the operator applies force directly with the electric drill, the force will inevitably be different each time, and it is easy to be too large or too small, which cannot be accurately controlled. It should be balanced, so it tends to consume more processing time, and at the same time, it also creates more potential bad factors. ...
