Description

Technical Field

[0002] At present, with the rapid development of data center and cloud computing technologies, the performance and reliability of servers are of crucial importance. As a key component to ensure the stable operation of servers, the assembly quality of heat dissipation fans directly affects the heat dissipation efficiency and service life of servers.

[0003] In order to ensure the heat dissipation efficiency of servers, the heat dissipation fan modules currently used on servers are usually assembled by multiple groups of heat dissipation fans. The assembly process is relatively cumbersome. Therefore, at present, the assembly process of server heat dissipation fan modules mostly relies on manual operation. Workers sequentially take the fan brackets and heat dissipation fans, arrange and assemble the heat dissipation fans in the fan brackets and then lock and fix them to complete the assembly of the heat dissipation fan module. However, on the one hand, manual assembly has low operation efficiency, is difficult to meet the needs of large-scale production, and long-term repetitive labor is likely to cause worker fatigue, resulting in a decline in assembly accuracy and an increase in product defect rate; on the other hand, manual assembly has a high cost, increasing the manufacturing cost of the heat dissipation fan module. Therefore, it is necessary to develop a server heat dissipation fan module assembly equipment that can replace manual labor to improve production efficiency, ensure product quality, and reduce production costs.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. By setting a rotary clamping and positioning component and a riveting component on the base, and setting a clamping component based on a manipulator, the rotary clamping and positioning component sets a cable positioning and clamping component on the first sliding seat, sets a first synchronous clamping cylinder and a first positioning and clamping plate on the adsorption seat, and sets a vacuum suction nozzle for adsorbing the fan bracket and a positioning rod for positioning the fan bracket between the first positioning and clamping plates. First, the manipulator drives the clamping component to pick up the fan bracket and place it between the first positioning and clamping plates, and the fan bracket is positioned based on the positioning rod. The positioned fan bracket is adsorbed and fixed on the adsorption seat through the vacuum suction nozzle. Subsequently, the manipulator picks up the heat dissipation fan from the tray and arranges it in the fan bracket. The first synchronous clamping cylinder drives the first positioning and clamping plate 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 cable of the heat dissipation fan from affecting the assembly process, the cable positioning and clamping component drives the sliding plate to slide through the pushing cylinder, so that the pushing block abuts against the abutting plate, causing the abutting plate to rotate inward to enclose the cable between the arc-shaped clamping blocks. When it is necessary to open, the pushing cylinder drives the sliding plate to return, so that the pushing block disengages from the abutting plate, and the return spring drives the abutting plate to return, causing the arc-shaped clamping blocks to open. Finally, the rotary drive motor drives the rotary seat and the fan bracket to rotate so that the side of the fan bracket faces upward. Subsequently, the riveting component drives the screw drive shaft to rotate through the screw drive motor, moving the second sliding seat directly above the rotary clamping and positioning component. Then, the first vertical cylinder drives the first lifting seat and the rivet sleeve feeding gun to descend to place the rivet sleeve on the fan bracket. Subsequently, the second vertical cylinder drives the second lifting seat and the rivet feeding gun to descend to insert the rivet into the rivet sleeve. Then, the riveting gun 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 drives the clamping component to clamp the heat dissipation fan module and move it into the server, thus avoiding manual assembly, improving the assembly efficiency of the heat dissipation fan module, and reducing the production cost;

[0017] 2. By respectively arranging a tray loading component and a tray placing component on the base, arranging a tray storage component on the base, and arranging a handling and assembling component based on a robotic arm, the trays carrying heat dissipation fans are stacked at the bottom of the double-layer material truck. By pushing the double-layer material truck into the base, the trays stacked at the bottom of the double-layer material truck are conveyed to the support bracket through the roller conveyor line. Subsequently, the lead screw drive motor drives the lead screw lifting shaft to rotate, thereby driving the support bracket and the trays stacked on the support bracket to rise to the loading station on the surface of the base. At this time, the robotic arm drives the clamping component to move, so as to clamp and transport the heat dissipation fans in the tray into the rotary positioning and clamping component for assembly. The tray placing component is provided with blocking rods at both ends of the horizontal sliding seat, and a positioning abutting rod and a positioning support block are arranged on the horizontal sliding seat based on a positioning abutting cylinder. The tray is positioned by the positioning abutting rod abutting against both sides of the tray along the conveying direction, and the tray is lifted by the positioning support block so that the uppermost tray is separated from the bottom tray. Subsequently, the horizontal sliding component drives the empty tray to be conveyed to the tray storage component. The tray storage component is provided with a fourth lifting cylinder on the storage plate, and a lifting cylinder is arranged at the telescopic end of the fourth lifting cylinder. At the same time, a lifting seat is arranged at the telescopic end of the lifting cylinder, and a lifting block is arranged on the lifting seat based on a lifting cylinder. When the empty tray moves to the bottom of the storage plate, first, the fourth lifting cylinder and the lifting cylinder drive the lifting seat to descend, and at the same time, the lifting cylinder drives the lifting block to move outwards so that the empty trays are stacked together. Subsequently, the lifting cylinder drives the lifting block to move inwards to the side of the bottommost tray to lift the edge of the tray. Then, the fourth lifting cylinder and the lifting cylinder drive the lifting seat to rise. When the number of empty trays in the storage plate reaches the upper limit, the fourth lifting cylinder and the lifting cylinder drive the lifting seat to descend to place the stacked empty trays on the upper layer of the double-layer material truck for storage, greatly reducing the time for taking and placing materials.

[0042] 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, thereby completing the preliminary assembly of the heat dissipation fan and the fan bracket. During this process, in order to prevent the cable 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 is necessary to open, 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 drive 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 drive shaft to rotate through the screw drive motor 54, moving the second sliding seat 52 to directly above the rotary 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 fix the heat dissipation fan to the fan bracket, thereby 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.
