[0027] Before using the positioning fixture, first place the motherboard inside the rotating frame 2, then start the dual-axis motor 7. The output shaft of the dual-axis motor 7 drives the lead screw 8 to rotate, causing the two sliding plates 9 to move inward, thus fixing the left and right sides of the motherboard. Simultaneously, start the dual-axis motor 7 and activate the electric slide rail 3. The electric slide rail 3 drives its two electric sliders 4 to slide towards each other, causing the two electric sliders 4 to move their clamping plates 5 towards each other, thus fixing the front and rear sides of the motherboard. After fixing, the motherboard can be surface-mounted. After processing, start one of the circulation pumps 15, and one of the circulating pumps... The circulating pump 15 draws coolant from the circulation pipe 16 and draws the coolant into the cooler 14, so that the cooler 14 transfers the heat in the coolant to the mounting bracket 10. Another circulating pump 15 then draws the cooled coolant back into the circulation pipe 16, thereby absorbing heat from the air. At the same time, the electric fan 13 is turned on, which blows cool air onto the motherboard after surface mounting, thereby accelerating the reduction of the temperature of the motherboard after surface mounting, so that the motherboard is cooled to a suitable temperature, preventing heat from accelerating the aging of electronic components. The protective net 26 can protect the electric fan 13 and prevent the electric fan 13 from getting stuck due to external factors.

[0028] Example 2: Based on Example 1, refer to Figure 3 and Figure 4 As shown, it also includes a rotating rod 17, a worm gear 18, a drive motor 19, and a worm 20. The rotating rod 17 is connected to the front side of the rotating frame 2, and the worm gear 18 is fixedly connected to the rotating rod 17. The drive motor 19 is installed on the upper front side of the support frame 11 by bolt connection. The output shaft of the drive motor 19 is equipped with the worm 20 through a coupling, and the worm 20 meshes with the worm gear 18.

[0029] See Figure 1 and Figure 2 As shown, it also includes a protective disc 24. The protective disc 24 is installed on the upper front side of the support base 1 by welding. The rotating rod 17, worm gear 18, drive motor 19 and worm 20 are located inside the protective disc 24.

[0030] When the rotating frame 2 needs to be rotated, the drive motor 19 is started. The output shaft of the drive motor 19 drives the worm 20 to rotate. The worm 20 meshes with the worm wheel 18, causing the worm wheel 18 to drive the rotating rod 17 and the rotating frame 2 to rotate. This can drive the motherboard after the chip is mounted to rotate, so that it can make uniform contact with the cold air and improve the heat dissipation efficiency. The protective plate 24 can protect the rotating rod 17, the worm wheel 18, the drive motor 19 and the worm 20.

[0031] See Figure 7 and Figure 8As shown, it also includes a mounting bracket 21, a motor 22 and a spur gear set 23. The mounting bracket 21 is welded to the rear side of the middle of the fixed bracket 10. The motor 22 is mounted on the mounting bracket 21 by bolt connection. The spur gear set 23 is provided between the output shaft of the motor 22 and the rotating shaft 12. The spur gear set 23 consists of two gears that mesh.

[0032] See Figure 2 As shown, it also includes a protective shell 25. The protective shell 25 is installed on the upper rear side of the fixing frame 10 by welding. The mounting frame 21, motor 22 and spur gear set 23 are located inside the protective shell 25.

[0033] When the angle of the electric fan 13 needs to be adjusted, the motor 22 is started. The output shaft of the motor 22 drives the two gears of the spur gear set 23 to rotate. The rotation of the two gears drives the rotating shaft 12 and the support frame 11 to rotate, thereby changing the angle of the electric fan 13, so as to provide all-round heat dissipation for the motherboard. The protective shell 25 can protect the mounting bracket 21, the motor 22 and the spur gear set 23.

[0034] The above embodiments are provided for those skilled in the art to implement or use the present invention.
