Description

Technical Field

[0001] This invention relates to the field of server fan testing technology, specifically a universal testing platform for server fan backplanes. Background Technology

[0002] In the process of server manufacturing and maintenance, the performance testing of server fans is crucial. As a key heat dissipation component that ensures stable server operation, the performance of server fans directly affects the server's operational stability and lifespan.

[0003] Existing fan testing platforms lack precise positioning structures when placing the fan backplane, typically relying on simple placement slots or manual placement. This makes the backplane prone to misalignment during subsequent lifting, lowering, and docking operations. Furthermore, height adjustment in these platforms largely depends on manual operation. Manual height adjustment is not only labor-intensive but also difficult to control. The platform requires manual intervention in multiple steps, including connector disconnection, backplane height reduction, and upper casing opening, increasing operator workload and time-consuming resetting processes, hindering rapid preparation for the next test. Therefore, this paper proposes a universal server fan backplane testing platform. Summary of the Invention

[0004] The purpose of this invention is to provide a universal testing platform for server fan backplanes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a universal test platform for server fan backplanes, including a test bench, a test fixture assembly connected to the top of the test bench, a fan backplane body provided on one side of the test fixture assembly, and the test fixture assembly being used to position and connect the fan backplane body to be tested;

[0006] The test fixture assembly includes an upper housing, a lower housing, and a lifting mechanism, wherein the lifting mechanism is used to adjust the height of the fan backplate body during testing.

[0007] A first horizontal plate is fixed to the bottom of the inner wall of the upper housing. A barcode scanner and several second cylinders are fixed to one side of the top of the first horizontal plate. A first connector located below the first horizontal plate is fixed to the push rod end of the second cylinder. The second cylinder is used to push the first connector to move.

[0008] The lower housing is hinged to two sides with a first cylinder.

[0009] The lifting mechanism includes a third cylinder and several fixed frames. A push plate is fixed to the push rod end of the third cylinder, and sliding frames are fixed to both ends of the push plate. The top of the sliding frame is provided with two inclined surfaces.

[0010] A sliding rod is slidably connected to the inner side of the fixed frame, and a support frame is fixed to the top of the sliding rod. A bearing that is rolled on the inclined surface is connected to one side of the support frame.

[0011] Preferably, the push rod ends of the two first cylinders are hinged to both sides of the upper housing, and an operation panel is installed on one side of the front of the lower housing. The upper housing and the lower housing are hinged together.

[0012] When the first cylinder push rod extends, the upper housing is in the open state; when the first cylinder push rod retracts, the upper housing is in the closed state.

[0013] Preferably, a connecting frame is installed on one side of the back of the lower housing, and a cable outlet is provided on the top of the connecting frame.

[0014] Preferably, a second horizontal plate is fixed to the top of the support frame;

[0015] When the bearing moves upward along the inclined plane, the second horizontal plate is in an elevated state; when the bearing moves downward along the inclined plane, the second horizontal plate is in a lowered state.

[0016] Several limiting blocks are fixed to the top of the second horizontal plate, and the limiting blocks are used to limit the movement of the fan back plate body around its perimeter.

[0017] Preferably, the top of the second horizontal plate is provided with a placement groove, and a proximity sensor is installed inside the placement groove. The proximity sensor is used to detect the placement status of the fan back plate body.

[0018] Preferably, positioning posts are fixed on both sides of the top of the second horizontal plate;

[0019] The fan backplate body has positioning holes on both sides of the top, and the positioning pin is adapted to the inside of the positioning hole.

[0020] Preferably, the top of the fan backplate body is connected to a plurality of second connectors, and the first connector can be inserted into the second connectors to achieve electrical connection;

[0021] The third cylinder and the mounting bracket are both fixed to the bottom of the inner wall of the lower housing.

[0022] Preferably, the test bench is equipped with test equipment, and the signal terminal of the test equipment is connected to the first connector via a wire;

[0023] When the first connector mates with the second connector, the testing equipment is able to perform electrical performance tests on the fan backplate body mounted on the test fixture assembly.

[0024] Preferably, a drawer is provided on one side of the test bench for storing a mouse and keyboard;

[0025] The top of the test bench is connected to an anti-static layer, and the bottom of the lower housing is connected to the top of the anti-static layer.

[0026] Preferably, the test stand is equipped with a display screen on top and handles on both sides of the lower housing.

[0027] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects:

[0028] First, the dual positioning structure ensures accurate placement of the fan backplate body. The limiting block limits the fan backplate body around its perimeter, and the positioning holes and positioning posts are matched to avoid positional deviations during subsequent lifting, docking and other operations. In addition, the proximity sensor verifies the placement status in real time. Only when the correct placement is confirmed will the subsequent process be triggered, which greatly reduces test failures caused by placement deviations and lays a solid foundation for subsequent key steps such as barcode scanning and connector docking.

[0029] Second, through the linkage structure of the third cylinder, sliding frame, support frame and other components of the lifting mechanism, the main body of the fan back panel can be smoothly raised to the target height. The automatic height adjustment method is not only more labor-saving than manual adjustment, but also controls the height parameters to ensure that the main body of the fan back panel can be connected to the barcode scanner and the first connector, meeting the strict requirements of different testing stages for the height of the main body of the fan back panel and adapting to diverse testing scenarios.

[0030] 3. After the barcode information of the fan back panel is entered by scanning the barcode, the testing equipment can quickly match the corresponding testing software and adjust the load size and characteristics according to the rated parameters of different fans. It can simulate various load conditions in the actual operation of the server, so that the test is no longer a general test with a unified standard, but a special test that fits the characteristics of each fan back panel and can identify potential problems under specific conditions.

[0031] Fourth, after the test is completed, each cylinder can be controlled to move in sequence to achieve reset operations such as connector separation, backplate height reduction, and upper shell opening. The entire reset process does not require manual intervention. Only the placement and removal of the fan backplate body need to be completed manually. This not only reduces the workload of operators, but also quickly prepares for the next test, making the test process smoother and improving the overall test efficiency. Attached Figure Description

[0049] Example

[0050] Please see Figure 1-13 The present invention provides a technical solution: a universal test platform for server fan backplanes, including a test bench 1, a test fixture assembly 2 connected to the top of the test bench 1, and a fan backplane body 7 provided on one side of the test fixture assembly 2. The test fixture assembly 2 is used to position and connect the fan backplane body 7 to be tested. As a key heat dissipation component to ensure the stable operation of the server, the performance of the fan directly affects the operational stability and lifespan of the server. The fan backplane body 7 that controls the server fan often requires a customized test platform.

[0051] The test fixture assembly 2 includes an upper housing 21, a lower housing 22, and a lifting mechanism 29. The lifting mechanism 29 is used to adjust the height of the fan backplate body 7 during testing. A first horizontal plate 26 is fixed to the bottom of the inner wall of the upper housing 21. A barcode scanner 27 and several second cylinders 28 are fixed to one side of the top of the first horizontal plate 26. The barcode scanner 27 is used to scan the barcode of the fan backplate body 7 and record the information into the test device 6. A first connector 212 located below the first horizontal plate 26 is fixed to the push rod end of the second cylinder 28. The second cylinder 28 is used to push the first connector 212 to move. The first connector 212 is fixed to the push rod end of the second cylinder 28 and can be pushed by the second cylinder 28 for insertion and removal.

[0052] Two first cylinders 23 are hinged to both sides of the lower housing 22; the push rod ends of the two first cylinders 23 are respectively hinged to both sides of the lower housing 22, and their push rod ends are hinged to both sides of the upper housing 21. The opening and closing of the upper housing 21 is controlled by the extension and retraction of the push rods of the first cylinders 23; the push rod ends of the two first cylinders 23 are hinged to both sides of the upper housing 21, and an operation panel 210 is installed on one side of the front of the lower housing 22. The upper housing 21 and the lower housing 22 are hinged together; when the push rod end of the first cylinder 23 extends, the upper housing 21 is in the open state; when the push rod end of the first cylinder 23 retracts, the upper housing 21 is in the closed state. The retraction of the push rod of the first cylinder 23 pulls the upper housing 21 to close, creating a stable and shielded environment for testing.

[0053] A connecting frame 24 is installed on one side of the back of the lower housing 22. The top of the connecting frame 24 is provided with a wire outlet 25. The test bench 1 and the test fixture assembly 2 are connected by a quick connector. The connector is located inside the connecting frame 24, and the wires pass through the wire outlet 25. The wire outlet 25 faces upward, which can play a certain role in preventing mistaken identity.

[0054] The lifting mechanism 29 includes a third cylinder 291 and several fixed frames 292. The push rod end of the third cylinder 291 is fixed with a push plate 296. Both ends of the push plate 296 are fixed with sliding frames 298. The sliding frames 298 are slidably connected to the inner wall of the lower housing 22 via slide rails. The top of the sliding frames 298 is provided with two inclined surfaces 297. The push rod of the third cylinder 291 extends out and pushes the push plate 296 and the sliding frames 298 to move forward and upward.

[0055] A sliding rod 295 is slidably connected to the inner side of the fixed frame 292. A support frame 293 is fixed to the top of the sliding rod 295. A bearing 294 is connected to one side of the support frame 293 and is rolled on the inclined surface 297. The inclined surface 297 on the sliding frame 298 pushes the bearing 294 upward. Since the bearing 294 is mounted on the support frame 293, and the support frame 293 is fixedly connected to the sliding rod 295 and the second horizontal plate 211, the entire platform supporting the fan back plate body 7 is vertically lifted.

[0056] The support frame 293 has a second horizontal plate 211 fixed to its top. When the bearing 294 moves upward along the inclined plane 297, the second horizontal plate 211 is in a raised state. When the bearing 294 moves downward along the inclined plane 297, the second horizontal plate 211 is in a lowered state. The top of the second horizontal plate 211 has several limiting blocks 213 fixed to it. The limiting blocks 213 are used to limit the fan back plate body 7 around its perimeter. The fan back plate body 7 is placed between the multiple limiting blocks 213 on the second horizontal plate 211 to ensure that the positioning holes 71 on it are aligned and the positioning pins 214 are inserted.

[0057] The top of the second horizontal plate 211 is provided with a placement groove, and a proximity sensor 215 is installed inside the placement groove. The output end of the proximity sensor 215 is electrically connected to the input end of the test equipment 6. The proximity sensor 215 is used to detect the placement status of the fan back plate body 7. When the proximity sensor 215 detects that the fan back plate body 7 has been placed in place, it sends a signal. Positioning posts 214 are fixed on both sides of the top of the second horizontal plate 211. Positioning holes 71 are opened on both sides of the top of the fan back plate body 7. The positioning posts 214 are adapted to the inside of the positioning holes 71 to raise the fan back plate body 7 and its second connector 72 to the preset test height, ready to dock with the first connector 212 above.

[0058] Several second connectors 72 are connected to the top of the fan backplate body 7. The first connector 212 can be inserted into the second connector 72 to achieve electrical connection. The third cylinder 291 and the fixing bracket 292 are both fixed to the bottom of the inner wall of the lower housing 22.

[0059] Test bench 1 is equipped with test device 6, model K1149S or K1149A. Depending on the test requirements of the server's fan backplane body 7, test device 6 adjusts the load size and characteristics according to the rated parameters and test requirements of different fans, simulating various load conditions of the fan in the actual server operating environment. This allows for comprehensive performance testing of the fan under different load conditions. A suitable model is selected, and the signal terminal of test device 6 is connected to the first connector 212 via a wire. Test device 6 then begins comprehensive electrical performance testing of the fan backplane body 7. Test device 6 can simulate various load conditions and test the performance of the fan backplane under different conditions. After the first connector 212 mates with the second connector 72, test device 6 can perform electrical performance testing on the fan backplane body 7 mounted on test fixture assembly 2.

[0060] A drawer 4 is provided on one side of the test bench 1. The drawer 4 is used to place a mouse and keyboard. The mouse and keyboard are used to input test information. The output terminals of the mouse and keyboard are connected to the input terminals of the test equipment 6. An anti-static layer 3 is connected to the top of the test bench 1. The bottom of the lower housing 22 is connected to the top of the anti-static layer 3. A display screen 5 is provided on the top of the test bench 1. Handles are provided on both sides of the lower housing 22. The input terminal of the display screen 5 is connected to the output terminal of the test equipment 6. The display screen 5 displays the test results.

[0061] Working principle: When testing the server fan backplate body 7, after the operator turns on the equipment, the first cylinder 23 of the lower housing 22 extends the push rod end, opening the upper housing 21. The fan backplate body 7 to be tested is then placed on top of the second horizontal plate 211. During placement, several limiting blocks 213 fixed on the top of the second horizontal plate 211 limit the fan backplate body 7 around its perimeter, preventing it from shifting position during subsequent operations. On the other hand, the positioning holes 71 on both sides of the top of the fan backplate body 7 are matched with the positioning posts 214 fixed on both sides of the top of the second horizontal plate 211, further realizing the positioning of the fan backplate body 7 and ensuring accurate placement. At the same time, the proximity sensor 215 installed inside the placement slot on the top of the second horizontal plate 211 will detect the placement status of the fan backplate body 7 in real time. When it is detected that the fan backplate body 7 has been correctly placed, a signal will be sent to the testing equipment 6.

[0062] After receiving the signal from the proximity sensor 215, the first cylinder 23 is controlled to retract its push rod end. Since the push rod ends of the two first cylinders 23 are hinged to both sides of the upper housing 21, and the upper housing 21 and the lower housing 22 are hinged together, under the pulling force of the retraction of the push rod ends of the first cylinders 23, the upper housing 21 will rotate around the hinge point and gradually switch from the open state to the closed state, providing a closed and stable environment for subsequent scanning and connection operations.

[0063] After the upper housing 21 is closed, the push rod end of the third cylinder 291 extends, pushing the push plate 296 fixed thereto to move. The sliding frame 298 fixed at both ends of the push plate 296 moves together with the push plate 296, and the two inclined surfaces 297 provided on the top of the sliding frame 298 are in rolling connection with the bearing 294 connected to one side of the support frame 293. As the sliding frame 298 moves, the bearing 294 will roll upward along the inclined surface 297. Since the bottom of the support frame 293 is fixed to the top of the slide rod 295 which is slidably connected to the inside of the fixed frame 292, and the fixed frame 292 is also fixed to the bottom of the inner wall of the lower housing 22, when the bearing 294 moves upward along the inclined surface 297, it will drive the support frame 293 and the slide rod 295 to slide upward along the inside of the fixed frame 292, thereby raising the second horizontal plate 211 fixed to the top of the support frame 293, and finally raising the fan back plate body 7 placed on the second horizontal plate 211 to the target height.

[0064] After the fan backplate body 7 reaches the designated height, the barcode scanner 27 fixed on the top side of the first horizontal plate 26 at the bottom of the inner wall of the upper shell 21 starts to work, scans the barcode on the fan backplate body 7, and enters the detection information into the inside of the test equipment 6 installed inside the test bench 1. The test equipment 6 will match the corresponding test software according to the scanning result. The test equipment 6 adjusts the load size and characteristics according to the rated parameters and test requirements of different fans to simulate various load conditions of the fan in the actual server operating environment.

[0065] After the scanning is completed and the test equipment 6 completes the parameter adjustment, several second cylinders 28 fixed on one side of the top of the first horizontal plate 26 receive the command, and their push rod ends extend to push the first connector 212 fixed to it and located below the first horizontal plate 26 to move. Since several second connectors 72 are connected to the top of the fan back plate body 7, and the fan back plate body 7 is at a suitable height at this time, the first connector 212 will be inserted into the second connector 72 to realize the electrical connection between the two. The signal end of the test equipment 6 is stably connected to the first connector 212 through the wire.

[0066] Once the first connector 212 and the second connector 72 successfully mate and establish an electrical connection, the testing equipment 6 officially begins electrical performance testing of the fan backplate body 7. During the test, the operator can input test information using the mouse and keyboard located in the drawer 4 on one side of the test bench 1. Simultaneously, the display screen 5 on the top of the test bench 1 will display the test results in real time, facilitating the operator to monitor the test progress and view the test data.

[0067] After the test is completed, the system will control each component to reset in sequence: the push rod end of the second cylinder 28 retracts, causing the first connector 212 to separate from the second connector 72; the push rod end of the third cylinder 291 retracts, pulling the push plate 296 and the sliding frame 298 to move in the opposite direction, and the bearing 294 rolls down the inclined plane 297, causing the second horizontal plate 211 and the fan back plate body 7 to be lowered to the initial height; the push rod end of the first cylinder 23 extends, pushing the upper housing 21 to open, and the operator can then take out the tested fan back plate body 7, completing a complete test process.

[0068] In summary, the dual positioning structure ensures the precise placement of the fan backplate body 7. The limiting block 213 limits the fan backplate body 7 around its perimeter, and the positioning hole 71 matches the positioning post 214 to avoid positional deviations during subsequent lifting, docking, and other operations. In addition, the proximity sensor 215 verifies the placement status in real time. Only when the correct placement is confirmed will the subsequent process be triggered, which greatly reduces test failures caused by placement deviations and lays a solid foundation for subsequent key steps such as barcode scanning and connector docking.

[0069] Through the linkage structure of components such as the third cylinder 291, sliding frame 298, and support frame 293 of the lifting mechanism 29, the fan backplate body 7 can be smoothly raised to the target height. The automated height adjustment method is not only more labor-saving than manual adjustment, but also controls the height parameters to ensure that the fan backplate body 7 can be connected to the barcode scanner 27 and the first connector 212, meeting the strict requirements of different testing stages for the height of the fan backplate body 7 and adapting to diverse testing scenarios.

[0070] After the barcode information of the fan backplate body 7 is entered by the barcode scanner 27, the testing equipment 6 can quickly match the corresponding testing software and adjust the load size and characteristics according to the rated parameters of different fans. It can simulate various load conditions in the actual operation of the server, so that the test is no longer a general test with a unified standard, but a special test that fits the characteristics of each fan backplate, and can investigate potential problems under specific conditions.

[0071] After the test is completed, each cylinder can be controlled to move in sequence to achieve reset operations such as connector separation, backplate height reduction, and upper housing 21 opening. The entire reset process does not require manual intervention. Only the placement and removal of the fan backplate body 7 need to be completed manually. This not only reduces the workload of operators, but also quickly prepares for the next test, making the test process smoother and improving the overall test efficiency.
