As a key component to ensure the stable operation of the server, the assembly quality of the cooling fan directly affects the server's cooling efficiency and service life.

[0003] In order to ensure the heat dissipation efficiency of the server, the cooling fan module currently used on the server is usually assembled from multiple groups of cooling fans, and the assembly process is relatively cumbersome. Therefore, at this stage, the assembly process of the server cooling fan module mostly relies on manual operation. Workers take out the fan bracket and the cooling fan in turn, arrange and assemble the cooling fans in the fan bracket, and then lock and fix them to complete the assembly of the cooling fan module. However, on the one hand, manual assembly has low operating efficiency and is difficult to meet large-scale production needs.

[0027] Brief description of the usage process: First, the manipulator 6 drives the clamping assembly 7 to pick up the fan bracket and place it between the first positioning clamping plates 49, and the positioning of the fan bracket is achieved based on the positioning rod 411. The positioned fan bracket is adsorbed and fixed on the adsorption seat 44 through the vacuum suction nozzle 410. Subsequently, the manipulator 6 picks up the heat dissipation fan from the tray and arranges it in the fan bracket. The first synchronous clamping cylinder 48 drives the first positioning clamping plates 49 to clamp the fan bracket, thus completing the preliminary assembly of the heat dissipation fan and the fan bracket. During this process, in order to prevent the cables of the heat dissipation fan from affecting the assembly process, the cable positioning clamping assembly 47 drives the sliding plate 476 to slide through the pushing cylinder 478, so that the pushing block 477 abuts against the abutting plate 474, causing the abutting plate 474 to rotate inward to enclose and position the cable between the arc-shaped clamping blocks 473. When it needs to be opened, the pushing cylinder 478 drives the sliding plate 476 to return, so that the pushing block 477 disengages from the abutting plate 474, and the return spring 475 drives the abutting plate 474 to return, causing the arc-shaped clamping blocks 473 to open. Finally, the rotation driving motor 43 drives the rotating seat 42 and the fan bracket to rotate so that the side of the fan bracket faces upward. Subsequently, the riveting assembly 5 drives the screw driving shaft to rotate through the screw driving motor 54, moving the second sliding seat 52 to directly above the rotating clamping and positioning assembly 4. Then, the first vertical cylinder 58 drives the first lifting seat 510 and the rivet sleeve feeding gun 512 to descend to place the rivet sleeve on the fan bracket. Subsequently, the second vertical cylinder 59 drives the second lifting seat 511 and the rivet feeding gun 513 to descend to insert the rivet into the rivet sleeve. Then, the riveting gun 514 performs riveting to rivet and fix the heat dissipation fan on the fan bracket, thus completing the automatic assembly of the heat dissipation fan module. After the assembly is completed, the manipulator 6 drives the clamping assembly 7 to clamp the heat dissipation fan module and move it into the server.
