在筆記本電腦中，通常採用風扇對發熱電子元件進行散熱。傳統風扇包括輪轂及扇葉，而輪轂則包括一框體及接合在框體內的軸心。在傳統輪轂的製造過程中，往往將軸心通過一軸套鉚接在框體內；然而鉚接用的軸套需要車削加工製作後再跟框體鉚接，制程較為複雜而且費用也高。另一種則通過將框體與軸心放在模具中通過埋入射出再次成型；然而由於軸心及框體的尺寸較小，在高溫模具中難以實施快速自動化，並容易高溫損害元件。 In notebook computers, fans are often used to dissipate heat-generating electronic components. A conventional fan includes a hub and a blade, and the hub includes a frame and an axis engaged in the frame. In the manufacturing process of the conventional wheel hub, the shaft core is often riveted into the frame body through a sleeve; however, the sleeve for the riveting needs to be turned and then riveted with the frame body, and the process is complicated and costly. The other is re-formed by placing the frame and the shaft in the mold by burying; however, due to the small size of the shaft and the frame, it is difficult to implement rapid automation in the high-temperature mold, and it is easy to damage the element at a high temperature.

有鑒於此，有必要提供一種簡單、快速的風扇輪轂的製造方法。 In view of this, it is necessary to provide a simple and fast method of manufacturing a fan hub.

一種風扇輪轂的製造方法，其包括以下幾個步驟：提供一治具，該治具具有一主體部及支撐部，該支撐部中心設置定位孔；提供一轉軸插設在定位孔中；提供一框體，該框體包括一蓋體及自蓋體周緣延伸的側壁，該側壁罩設在所述治具的主體部上，所述蓋體抵靠在所述治具的支撐部及轉軸上；及 通過鐳射焊接將轉軸與框體的蓋體接合形成輪轂。 A manufacturing method of a fan hub, comprising the following steps: providing a jig having a main body portion and a supporting portion, the supporting portion is centrally provided with a positioning hole; and a rotating shaft is inserted in the positioning hole; a frame body comprising a cover body and a side wall extending from a periphery of the cover body, the side wall is disposed on the main body portion of the jig, and the cover body abuts on the support portion and the rotating shaft of the jig ;and The rotating shaft is joined to the cover of the frame by laser welding to form a hub.

相較於現有技術，本發明鐳射焊接熱輸入量較傳統電弧焊接溫度低，縮短輪轂製造的工時，有效的提高生產效率。 Compared with the prior art, the laser welding heat input amount of the invention is lower than the conventional arc welding temperature, shortening the working time of the hub manufacturing, and effectively improving the production efficiency.

A central portion 310 is formed in the middle of the cover body 31. The rotating shaft 40 is engaged at a center position of the center portion 310. The central portion 310 of the cover body 31 is not provided with an opening that is coupled to the rotating shaft 40 corresponding to the position of the rotating shaft 40. The jig 200 includes a base 21, a main body portion 22 extending upward from the top surface of the base 21, and a self-supporting portion 23. The base 21, the main body portion 22, and the support portion 23 are both cylindrical and coaxially disposed. The outer diameter of the main body portion 22 is equal to or slightly smaller than the inner diameter of the side wall 33 of the frame body 30, so that the side wall 33 of the frame body 30 is sleeved on the top of the main body portion 22. A receiving slot 230 is defined in the middle of the supporting portion 23, and a positioning hole 231 is disposed in the center of the supporting portion 23 for placing The rotating shaft 40.

相較於現有技術，本發明鐳射焊接熱輸入量較傳統電弧焊接溫度低，對框體30及轉軸40之熱影響區及變型量均可降至最低程度。此外，鐳射可在空氣中傳輸，而不似電子束焊接須在真空環境中操作，因此對框體30及轉軸40尺寸限制較少，焊接前之校準工作尤其容易，亦無工作消磁之困擾。利用鐳射焊接只要將框體30與轉軸40利用治具200固定貼平，而焊接前的框體30上不設置結合轉軸40的開孔也可。制程時間只要幾秒的時間，還可以跟自動化及產線作搭配，有效的提高生產效率，接合的強度也能符合設計需求。 Compared with the prior art, the laser welding heat input amount of the invention is lower than the conventional arc welding temperature, and the heat affected zone and the deformation amount of the frame 30 and the rotating shaft 40 can be minimized. In addition, the laser can be transmitted in the air, and the electron beam welding is not required to operate in a vacuum environment. Therefore, the frame 30 and the rotating shaft 40 are less limited in size, and the calibration work before welding is particularly easy, and there is no work degaussing. The laser welding is used to fix the frame 30 and the rotating shaft 40 to each other by the jig 200, and the opening 30 of the rotating shaft 40 may not be provided on the frame 30 before welding. The process time can be matched with the automation and production line in a few seconds, which can effectively improve the production efficiency and the strength of the joint can meet the design requirements.
