Description
Technical Field
[0001] This invention relates to the field of testing equipment technology, specifically to a liquid-cooled fluid connector airtight pressure testing device. Background Technology
[0002] Liquid-cooled fluid connectors are key components in liquid-cooled heat dissipation systems, primarily used to enable rapid connection and disconnection of coolant lines to ensure efficient coolant transfer while maintaining sealing and reliability during the connection process. After production, an airtight pressure test is required. Dry gas (such as nitrogen or compressed air) is filled into the connector's internal cavity, and its sealing performance is assessed by monitoring pressure decay or directly measuring leakage (to prevent air intake and airlock formation during operation, or coolant leakage). During the airtightness test, one end of the connector is sealed with a special clamp (such as a silicone plug), and the other end is connected to the air supply line of the testing device. During the pressure test, air is injected into the connector's internal cavity... Fill the connector with liquid (such as deionized water, simulating coolant), apply a load higher than the working pressure, and verify its sealing performance (no liquid leakage) and structural strength (no deformation or cracking) under high pressure. Connect an vent valve (independent of the connector, used to remove air bubbles in the internal cavity to avoid affecting pressure detection) at the highest point of the pipeline. Turn on the plunger pump and slowly fill the connector cavity with deionized water (pressure increase rate ≤ 0.2 MPa / s, to avoid impact pressure). At the same time, open the vent valve until liquid flows out of the vent valve continuously without air bubbles (to ensure no gas residue in the internal cavity). Close the vent valve. If there is no liquid leakage, the pressure is stable, and the structure has no permanent deformation during the pressure holding period, the pressure resistance test is deemed qualified.
[0003] CN215677424U discloses a fluid connector airtight pressure withstand testing device, including a testing fixture. The testing fixture has an airflow channel, with a fixed interface and an air inlet at each end. At least two connector 1s and two connector 2s are connected to each end of the testing fixture. When multiple testing fixtures are connected sequentially, connector 1s are connected to adjacent connector 2s, and the fixed interface is connected to the air inlet of the adjacent testing fixture. Each connector 1 includes a threaded cylinder and a fixed rod, and connector 2 includes a connecting rod and a threaded head. The rotatable threaded cylinder... The threaded connection of the additional test fixture ensures a tight connection between the inflation port and the fixed interface of the other test fixture, while also allowing multiple test fixtures to be connected in series for convenient mass airtight pressure testing of fluid connectors. However, in existing liquid-cooled fluid connector airtight pressure testing devices, the sealing head is prone to dust and other impurities adhering to it and is easily damaged, affecting its sealing effect. At the same time, the sealing head is also prone to wear, which also affects the sealing gasket effect. Furthermore, the lack of guidance and limiting during docking can easily cause damage, thus affecting the accuracy of the test. After the test, it is not convenient to drain and reuse the liquid inside the connector, affecting the efficiency and effectiveness of the test. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] This liquid-cooled fluid connector airtight pressure withstand testing device, through the inclusion of a first lifting mechanism, allows for the following: When an airtight pressure withstand test is required on the liquid-cooled fluid connector, a loading / unloading robot grips the connector and inserts it into the first rubber ring. When the retaining ring on the connector's side wall abuts against the top of the rotating plate, it drives the rotating plate downwards. Simultaneously, it causes the moving block to slide downwards along the side wall of the second T-shaped guide rod, compressing the fourth spring. When the lower end of the first pushing plate abuts against the top of the moving plate, it pushes the protective ring downwards along the first annular groove, compressing the first spring and exposing the sealing head to ensure a seal at the bottom of the connector. Furthermore, as the moving block moves downwards, it drives the limiting block to move downwards synchronously. When sliding downwards along the first inclined plane, the first triangular block is pushed into the first mounting cover. Simultaneously, the second spring is compressed, allowing the limiting block to pass over the first triangular block. Once the limiting block has passed, the first triangular block extends outwards under the action of the second spring, ensuring that the top of the limiting block abuts against the bottom of the first triangular block. This limits the rotation plate, ensuring that the connector and sealing head are guided and limited during connection, resulting in greater stability and reliability, and guaranteeing the connection effect. This, in turn, ensures the effectiveness of the airtight pressure test. Next, the connector is transported by a conveyor, and the airtight test head is connected to the top of the connector by an airtight test robot. Gas is then injected for an airtight test. After the airtight test is completed, the gas... The pressure test head is disconnected from the connector. Then, the connector continues to be transported via a conveyor. A pressure testing robot can connect the pressure test head to the connector, fill it with liquid for a pressure test, and disconnect the test head from the connector after the test. The connector continues to be transported via the conveyor. When the second inclined plane abuts against the side wall of the connecting plate, it pushes the first triangular block into the first mounting cover and separates it from the limiting block. At this time, the moving block can move upwards and reset under the action of the fourth spring. Simultaneously, the rotating plate drives the connector upwards and resets it, separating it from the sealing head. This allows the liquid inside the connector to fall into the collection tank. When the first triangular block can no longer move, and the connecting plate abuts against the second inclined plane, it can push the second... The moving plate moves closer to the connecting frame, while the third spring is compressed to ensure the connecting plate can pass over the second pushing plate. The protective ring moves upward and resets under the action of the first spring. The cleaning ring automatically cleans the surface of the sealing head, and the protective ring automatically protects the surface of the sealing head to ensure the accuracy of subsequent testing. Then, the fan can be started to blow air, and the electric heating ring is turned on to heat the air. The heated air is blown into the connector to ensure the efficiency and effect of drying. After drying, the connector is removed by the loading and unloading robot. When the liquid collection tank is rotated to an inclined position, the liquid inside can fall into the collection tank for collection and reuse, avoiding waste of liquid. Furthermore, continuous automated testing can improve the efficiency of testing.
[0019] This liquid-cooled fluid connector airtight pressure withstand testing device, through the setting of a drive mechanism and a second limiting mechanism, allows the following to occur during testing: When the rotating plate moves downward, and the rectangular block abuts against the third inclined surface, it pushes the second triangular block into the second mounting cover. Simultaneously, the sixth spring is compressed. At this time, under the action of the second limiting mechanism, the rotating plate will not rotate. After the test is completed, when the connector moves upward and resets with the rotating plate, and the rectangular block abuts against the bottom of the second triangular block, it can push the rotating rod and the rotating plate to rotate. The second mounting covers on the two support plates are arranged opposite each other, thereby driving the rotating plate to reciprocate. Furthermore, when the rotating rod rotates, the arc-shaped block can slide out from the arc-shaped groove and slide on the side wall of the fixed ring. At the same time, the fifth spring is compressed. After the rotation is completed, the arc-shaped block can abut against the arc-shaped groove under the action of the fifth spring, limiting the moving block. This allows the connector to reciprocate, resulting in higher efficiency and better effect in liquid discharge.
[0020] This liquid-cooled fluid connector airtight pressure withstand testing device, through the setting of a sealing mechanism, etc., during the test, when the connector moves downward with the rotating plate, after the connector is gradually fitted onto the side wall of the sealing head, as the rotating plate continues to move downward, it can drive the third push plate to move synchronously. When the third push plate abuts against the upper end of the push rod, it can push the lifting plate to move downward. At the same time, the seventh spring is stretched, thereby squeezing the coolant in the fixed box into the annular rubber bladder through the filling pipe. This causes the annular rubber bladder to gradually expand and abut against the inner wall of the connector, resulting in a better sealing effect and ensuring the accuracy of the test results. After the test is completed, when the connector moves upward and resets with the rotating plate, the lifting plate can move upward and reset under the action of the seventh spring, thereby drawing the gas in the annular rubber bladder back into the fixed box for temporary storage.

[0034] Please see Figures 1-11 This invention provides a liquid-cooled fluid connector airtightness withstand pressure testing device, including a conveyor 1, a loading / unloading robot 11, an airtightness testing robot 12, and a withstand pressure testing robot 13.

The rotation of the rotating rod 1407 is driven by a driving mechanism. Furthermore, the sealing head 1403 has a sealing mechanism on its side wall, which guides and limits the connection when it is connected to the sealing head 1403. At the same time, it can expand the annular rubber bladder 802 and press against the inner wall of the connector, resulting in a better sealing effect. After the test is completed, it is convenient to collect and reuse the liquid inside the connector, avoiding liquid waste. At the same time, it can automatically clean and protect the sealing head 1403, ensuring the accuracy of subsequent tests. Moreover, the use of continuous automated testing can improve the efficiency of testing.

When the retaining ring on the side wall of the connector abuts against the top of the rotating plate 1408, it can drive the rotating plate 1408 to move downward. When the lower end of the first push plate 206 abuts against the top of the moving plate 204, it can push the protective ring 1404 to slide downward along the first annular groove 201.

The movement of the first sliding plate 403 is driven by a pushing component. When the moving block 1406... When moving downwards, it can drive the limiting block 401 to move downwards synchronously. When the limiting block 401 slides downwards along the first inclined surface 406, it can push the first triangular block 405 into the first mounting cover 402. At the same time, the second spring 404 is compressed, so that the limiting block 401 can pass over the first triangular block 405. When the limiting block 401 passes over the first triangular block 405, the first triangular block 405 can extend outwards under the action of the second spring 404, and ensure that the top of the limiting block 401 abuts against the bottom of the first triangular block 405, thus limiting the rotation plate 1408.
[0039] Please see Figure 11 The pushing assembly includes a connecting plate 501 fixedly connected to the side wall of the first sliding plate 403, and a connecting frame 502 fixedly connected to the side wall of the frame 101.

When the second inclined surface 505 abuts against the side wall of the connecting plate 501, it can push the first triangular block 405. The first mounting cover 402 is retracted and disengaged from the limiting block 401. At this time, the moving block 1406 can move upward and reset under the action of the fourth spring 302. At the same time, the rotating plate 1408 drives the connector to move upward and reset and disengage from the sealing head 1403. At this time, the liquid in the connector can fall into the liquid collection tank 1412. When the first triangular block 405 can no longer move, the connecting plate 501 abuts against the second inclined surface 505, which can push the second pushing plate 504 to move closer to the connecting frame 502.

(To be tested) After completion, when the connector moves upward and resets with the rotating plate 1408, the rotating plate 1408 is driven to reciprocate through the drive mechanism. When the rotating rod 1407 rotates, the arc block 605 can slide out of the arc groove 602 and slide on the side wall of the fixed ring 601. At the same time, the fifth spring 606 is compressed. After the rotation is completed, the arc block 605 can abut against the arc groove 602 under the action of the fifth spring 606, limiting the moving block 1406, thereby enabling the connector to reciprocate, making the liquid discharge efficiency higher and the effect better.

A third [unclear - possibly a type of spring or spring] is provided on the top of each second triangular block 705. The inclined plane 706 and the rectangular block 707 can slide on the third inclined plane 706. When the rectangular block 707 abuts against the third inclined plane 706, it can push the second triangular block 705 into the second mounting cover 702. At the same time, the sixth spring 704 is compressed. At this time, under the action of the second limiting mechanism, the rotating plate 1408 will not rotate. After the test is completed, when the connector moves upward and resets with the rotating plate 1408, when the rectangular block 707 abuts against the bottom of the second triangular block 705, it can push the rotating rod 1407 and the rotating plate 1408 to rotate.
[0043] Please see Figure 6 The sealing mechanism includes a second annular groove 801 formed on the side wall of the sealing head 1403, and an annular rubber bladder 802 is fixedly connected in the second annular groove 801. The top of the mounting base 1402 is provided with a filling mechanism for filling the annular rubber bladder 802 with liquid. During the test, when the connector moves downward with the rotating plate 1408, after the connector is gradually fitted onto the side wall of the sealing head 1403, as the rotating plate 1408 continues to move downward, coolant is filled into the annular rubber bladder 802 through the filling mechanism, so that the annular rubber bladder 802 gradually expands and abuts against the inner wall of the connector, which makes the sealing effect better, ensures the accuracy of the test results, and also has a cooling effect, avoiding the influence of temperature rise after pressurization.
[0044] Please see Figure 7 The filling mechanism includes a fixed box 901 fixedly connected to the top of the mounting base 1402, and a lifting plate 902 connected to the fixed box 901 through a lifting assembly. A filling pipe 903 is fixedly connected to the side wall of the fixed box 901, and the other end of the filling pipe 903 passes through the mounting base 1402 and communicates with the annular rubber bladder 802. The lifting plate 902 is moved downward by the lifting assembly, so that the coolant in the fixed box 901 can be squeezed into the annular rubber bladder 802 through the filling pipe 903.
[0045] Please see Figure 4 and Figure 7 The lifting assembly includes two symmetrically arranged fourth T-shaped guide rods 1001 fixedly connected to the bottom of the fixed box 901, and a lifting plate 902 sleeved on the side wall of the fourth T-shaped guide rods 1001. A seventh spring 1002 is sleeved on the side wall of each fourth T-shaped guide rod 1001. A push rod 1003 is fixedly connected to the top of the lifting plate 902, and a third push plate 1004 is fixedly connected to the side wall of the rotating plate 1408. When the connector moves downward with the rotating plate 1408, after the connector is gradually sleeved on the side wall of the sealing head 1403, when the rotating plate 1408 continues to move downward, it can drive the third push plate 1004 to move synchronously. When the third push plate 1004 abuts against the upper end of the push rod 1003, it can push the lifting plate 902 to move downward, and at the same time the seventh spring 1002 is stretched.
[0046] Working Principle: During use, when an airtight pressure test is required on the liquid-cooled fluid connector, the loading / unloading robot 11 grips the connector and inserts it into the first rubber ring 1410. When the retaining ring on the side wall of the connector abuts against the top of the rotating plate 1408, it can drive the rotating plate 1408 to move downward. At the same time, it drives the moving block 1406 to slide downward along the side wall of the second T-shaped guide rod 301, and the fourth spring 302 is compressed. When the lower end of the first pushing plate 206 abuts against the top of the moving plate 204, it can push the protective ring 1404 to slide downward along the first annular groove 201. At the same time, the first spring 202 is compressed, thereby exposing the sealing head 1403, ensuring that the bottom of the connector can be sealed. Furthermore, when the moving block 1406 moves downward... When moving downwards, the limiting block 401 moves downwards synchronously. When the limiting block 401 slides downwards along the first inclined surface 406, it pushes the first triangular block 405 into the first mounting cover 402. At the same time, the second spring 404 is compressed, allowing the limiting block 401 to pass over the first triangular block 405. When the limiting block 401 passes over the first triangular block 405, the first triangular block 405 can extend outwards under the action of the second spring 404, ensuring that the top of the limiting block 401 abuts against the bottom of the first triangular block 405, thus limiting the rotation plate 1408. This ensures that when the connector is connected to the sealing head 1403, it can guide and limit the connection, making it more stable and reliable, ensuring the connection effect, and thus ensuring the effect of the airtight pressure test.
[0047] When the rotating plate 1408 moves downward, when the rectangular block 707 abuts against the third inclined surface 706, it can push the second triangular block 705 into the second mounting cover 702. At the same time, the sixth spring 704 is compressed. At this time, under the action of the second limiting mechanism, the rotating plate 1408 will not rotate.
[0048] As the connector moves downward with the rotating plate 1408, and after the connector is gradually fitted onto the side wall of the sealing head 1403, the rotating plate 1408 continues to move downward, driving the third push plate 1004 to move synchronously. When the third push plate 1004 abuts against the upper end of the push rod 1003, it pushes the lifting plate 902 downward. At the same time, the seventh spring 1002 is stretched, thereby squeezing the coolant in the fixed box 901 into the annular rubber bladder 802 through the filling pipe 903. This causes the annular rubber bladder 802 to gradually expand and abut against the inner wall of the connector, resulting in a better sealing effect and ensuring the accuracy of the test results. After the test is completed, when the connector moves upward and resets with the rotating plate 1408, the lifting plate 902 can move upward and reset under the action of the seventh spring 1002, thereby drawing the gas in the annular rubber bladder 802 back into the fixed box 901 for temporary storage.
[0049] Next, the connector is transported via conveyor 1. The airtightness test manipulator 12 drives the airtightness test head 1201 to connect with the top of the connector, and gas is injected for airtightness testing. After the airtightness test is completed, the airtightness test head 1201 is disconnected from the connector. Then, the connector is transported via conveyor 1 again. The pressure resistance test manipulator 13 drives the pressure resistance test head 1301 to connect with the connector, and liquid is injected for pressure resistance testing. After the pressure resistance test is completed, the pressure resistance test head 1301 is disconnected from the connector, and the connector is transported via conveyor 1 again. When the second inclined surface 505 abuts against the side wall of the connecting plate 501, it can push the first triangular block 405 to retract into the first mounting cover 402 and disengage from the limiting block 401. At this time, the moving block 1406 can move upward and reset under the action of the fourth spring 302. At the same time, the rotating plate 1408 drives the connector to move upward and reset and disengage from the sealing head 1403. At this time, the liquid in the connector can fall into the liquid collection tank 1412.
[0050] When the first triangular block 405 can no longer move, and the connecting plate 501 abuts against the second inclined surface 505, it can push the second push plate 504 to move closer to the connecting frame 502. At the same time, the third spring 506 is compressed to ensure that the connecting plate 501 can pass over the second push plate 504. The protective ring 1404 can move upward and reset under the action of the first spring 202. The cleaning ring 1405 can automatically clean the surface of the sealing head 1403, and the protective ring 1404 can automatically protect the surface of the sealing head 1403 to ensure the accuracy of subsequent testing.
[0051] Next, the blower 1502 can be started to blow air, and at the same time, the electric heating ring 1504 is turned on to heat the air. The heated air is blown into the connector to ensure the efficiency and effect of drying. After drying is completed, the connector is removed by the loading and unloading robot 11. When the liquid collection tank 1412 is rotated to the tilt position, the liquid inside can fall into the collection tank 1413 for collection and reuse, avoiding waste of liquid. In addition, continuous automated detection can improve the efficiency of testing.
[0052] After the test is completed, when the connector moves upward and resets with the rotating plate 1408, when the bottom of the rectangular block 707 abuts against the second triangular block 705, it can push the rotating rod 1407 and the rotating plate 1408 to rotate. The second mounting covers 702 on the two support plates 701 are arranged opposite each other, thereby driving the rotating plate 1408 to reciprocate. When the rotating rod 1407 rotates, the arc-shaped block 605 can slide out from the arc-shaped groove 602 and slide on the side wall of the fixing ring 601. At the same time, the fifth spring 606 is compressed. After the rotation is completed, the arc-shaped block 605 can abut against the arc-shaped groove 602 under the action of the fifth spring 606, limiting the moving block 1406, thereby enabling the connector to reciprocate, making the liquid discharge efficiency higher and the effect better.
