Please refer to Figure 2, which is a schematic flow diagram of the combination of the fan and the system board; Figures 3A-3B are schematic diagrams of the operation of the fan of the present invention placed on the system board. As shown in the figure, the inventive method comprises the following steps:

A step of moving the fan (S01): moving or transporting a fan 11 to a preset position 222 of a system board (such as a computer motherboard) 22, the fan 11 has a frame body 111 protrudingly provided with a fan end connector 12 Corresponds to a board end connector 221 on the system board 22 .

In this step, a mechanical device 26 is used to absorb (such as magnetic suction or vacuum suction) or grab an upper side of the fan 11 from a fan supply area (not shown), and then move the fan 11 to the system board 22 With the movement of the fan 11 , the fan end connector 12 corresponds to (that is, opposite to but not plugged or contacted with) the board end connector 221 (as shown in FIG. 3A ). The mechanical equipment (ie automatic mechanical equipment) 26 is any one or combination of a suction cup and a mechanical arm or a turntable.

In this step, the mechanical device 26 (such as a mechanical arm) places the frame body 111 of the fan 11 on the preset position 222 of the system board 22, and the mechanical device 26 exerts pressure on the upper side of the frame body 111 of the fan so that The fan-side connector 12 is directly connected (for example, plugged with a male-female connector or contacted with a metal contact) to the board-side connector 221 .

It should be noted that the frame body 111 is combined with the system board 22 through a combination means, and the combination means includes any one of screw lock, clamping, buckle, fastening and welding. For example, the mechanical device 26 exerts pressure on the frame body 111 to place the frame body 111 on the preset position 222, and the fan end is connected to The connector 12 bears the pressure and directly connects (for example, plugging of male and female connectors or contacting of metal contacts) the board end connector 221 downward. A fixing seat at the predetermined position 222 buckles or clamps the frame body 111 to fix the fan 11 on the system board 22 . Then the mechanical device 26 leaves the frame body 111 .

In another implementation, the mechanical device 26 (such as a mechanical arm) exerts pressure on the frame body 111 to place the frame body 111 at the preset position 222, and the fan end connector 12 bears the pressure and directly connects downward (such as male and female Connector insertion or metal contacts) the board end connector 221. The mechanical device 26 stays temporarily at the preset position 222 to support the frame body 111, and then the frame body 111 is locked and fixed on the system board 22 with a screw locking element by an automatic appliance, and then the mechanical device 26 is separated from the frame body 111.

In another alternative implementation, the mechanical device 26 (such as a suction cup) places the frame body 111 of the fan 11 on the preset position 222 of the system board 22, and then uses another press-in jig to fix the frame body of the fan 11 The upper side of 111 exerts pressure, and a fixed seat at the preset position 222 buckles or clamps the frame body 111 to fix the fan 11 on the system board 22, and the fan end connector 12 is forced downward. The board connector 221 is directly connected (such as plugging of male and female connectors or contacting of metal contacts).

Please continue to refer to Figure 4 for another schematic diagram of the combination of the fan and the system board. As shown in this figure, the difference from the aforementioned figure 2 is that before the step of moving the fan (SP01), a fan preparation step (SP00) is included, and the fan preparation step (SP00) is to integrally form the fan end connector 12 Or the one that is not integrally formed is protruded on the outside of the frame 111 of the fan 11 (details are as shown in FIG. 5 ). The fan end connector 12 is fixed to the frame body 111 and placed in the fan feeding area.

The combined means are, for example but not limited to, plug-in or snap-fit joints or adhesive joints or ultrasonic joints. Moreover, if it is a separate unit, the fan end connector 12 and the connector combining portion 114 can be assembled together by using automated mechanical equipment. But not limited thereto, the fan end connector 12 and the connector combining portion 114 can also be assembled manually.

Although it is shown in this figure that the fan end connector 12 is connected to a circuit board inside the fan 11 through an exposed electric wire. But not limited thereto, the fan end connector 12 can also be connected to a circuit board inside the fan 11 via a conductive element (such as an electrical wire or a metal pin) hidden in the frame body 111 .

The present invention uses the above method to automate the assembly of the fan 11 and the system board 22, especially the fan end connector 12 can be directly electrically connected to the end of the board through the pressure of the mechanical device 26 or the press-in jig. The connector 221 is used to improve the problems of the prior art that manual insertion and assembly are required.
