Description

Technical Field

[0001] This invention relates to the field of sealing testing technology, and more specifically, to a sealing testing device for a vacuum environment. Background Technology

[0002] Leakage testing is generally used to test the product to determine whether it is leaking. The testing methods can be basically divided into two types: internal pressurization with helium and external application of helium after evacuating the equipment.

[0003] In existing technologies, most instruments used for testing are sealing testers. The operating steps are as follows: connect the test probe of the sealing tester to the sealing cover, and start the tester to test the environment inside the sealing cover. However, the test probe can only test in a fixed position and cannot achieve all-round testing at the same time, thus reducing the testing efficiency. If the space inside the sealing cover is large and the venting point of the product under test is far from the position of the test probe, the filling gas needs a long time to spread to the area around the test probe before the test probe can start testing. This results in the test probe not being able to detect the gas in real time, further reducing the testing efficiency. Therefore, a sealing test device for a vacuum environment is proposed to improve the existing problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a sealing test device for vacuum environment.

[0010] The invention is further configured such that: the outer wall of the partition column is uniformly provided with rotating holes, the rotating holes can penetrate the side wall of the partition column and communicate with the rotating groove; the end of the first rotating rod away from the leaf can be connected to the end of the driven bevel gear away from the driving bevel gear through the rotating holes; the leaf is fan-shaped, the leaf can be evenly distributed in the circumferential direction in the inner ring of the partition plate, the leaf can be tightly fitted with each other, and the end of the second rotating rod away from the leaf can be rotatably connected to the inner ring wall of the partition plate.

[0011] By adopting the above technical solution, the blades gradually come together tightly during the flipping process, thereby sealing the middle of the ring of the partition plate. This divides the space inside the isolation cover, reducing the vacuum area inside the isolation cover so that the detection probe only needs to detect the vacuum area where the product under test is located. Furthermore, it allows the detection probe to perform directional detection on the divided vacuum area.

[0012] The invention is further configured such that: the lifting component includes a lifting motor, a lead screw disposed at the output end of the lifting motor, and a movable block sleeved on the lead screw; wherein, the lifting motor is located on the side of the support plate near the support frame, and a suspension plate is disposed in the middle of the side wall of the support plate near the support frame, and the side wall of the suspension plate can be connected to the bottom of the lifting motor; a movable groove is formed on the inner wall of the isolation cover, the movable groove can extend and be distributed along the height direction of the isolation cover, the lead screw is distributed in the movable groove, one end of the lead screw can be rotatably connected to the top of the inner wall of the isolation cover, and the other end can penetrate the side wall of the support plate and be connected to the output end of the lifting motor, a sealing ring is disposed at the penetration point between the lead screw and the support plate, the movable block can slide in the movable groove, and the side wall of the movable block can be connected to the outer annular wall of the isolation plate.

The sliding grooves can extend along the height direction of the isolation cover. A sliding block is provided in the sliding groove, and the side wall of the sliding block away from the sliding groove can be connected to the outer ring wall of the partition plate.

[0014] By adopting the above technical solution and through the design of the lifting component, the partition plate is brought close to the top of the product under test. On the one hand, the partition plate separates the vacuum area where the product under test is located from other vacuum areas, making the vacuum area to be detected smaller, and the detection probe only needs to detect the vacuum area where the product under test is located.

[0016] The present invention is further configured such that: detection grooves are formed on the sidewalls of the first detection spring, the second detection spring, and the third detection spring on the same side; the detection grooves are evenly distributed along the length direction of the first detection spring, the second detection spring, and the third detection spring; the detection probe is located in the detection groove; and anti-collision blocks are provided on the protruding sidewalls between the detection grooves.

[0017] By adopting the above technical solution, through the cooperation of the first detection spring, the second detection spring, and the third detection spring, and by utilizing the elastic characteristics of the spring itself, the first detection spring, the second detection spring, and the third detection spring can be made to fit tightly against the surface of the product to be tested, thereby allowing the detection probe to make close contact with the surface of the product to be tested, so that the detection probe can detect the gas at the leakage point in a timely manner.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] (1) By cooperating with the separation component and the detection component, on the one hand, the height of the detection probe can be adjusted according to the height of the product to be tested, so that the detection probe only needs to detect the vacuum area where the product to be tested is located, avoiding the situation that the space inside the isolation chamber is large and the gas spread time is long, thereby improving the detection speed and saving the detection time; on the other hand, according to the shape of the product to be tested, the surface of the product to be tested can be covered in a large area, so that the detection probe can detect the gas at the leakage point in a timely manner, avoiding the situation that the leakage point of the product to be tested is far away from the position of the detection probe and the gas cannot be detected in time, thereby improving the detection efficiency.

[0020] (2) As the blades gradually come together during the flipping process, they seal the middle of the ring of the partition plate, thereby dividing the space inside the isolation chamber. On the one hand, this reduces the space of the vacuum area inside the isolation chamber, so the detection probe only needs to detect the vacuum area where the product to be tested is located, avoiding the problems of a large space inside the isolation chamber and long gas propagation time, thus improving the detection speed and saving detection time. On the other hand, it allows the detection probe to detect the divided vacuum area in a directional manner, thereby improving the detection efficiency.

[0021] (3) By designing the lifting component, the partition plate is brought close to the top of the product to be tested. On the one hand, the partition plate separates the vacuum area where the product to be tested is located from other vacuum areas, making the vacuum area to be tested smaller. The detection probe only needs to detect the vacuum area where the product to be tested is located, avoiding the situation of large space inside the isolation cover and long gas propagation time, thereby improving the detection speed and saving detection time. On the other hand, it enables the detection probe to detect the separated vacuum area in a directional manner, thereby improving the detection efficiency.

[0022] (4) By cooperating with the first, second, and third detection springs and utilizing the elasticity of the springs themselves, the first, second, and third detection springs can be made to fit tightly against the surface of the product to be tested, thereby making the detection probe in close contact with the surface of the product to be tested. This allows the detection probe to detect the gas at the venting point in a timely manner, avoiding the situation where the venting point of the product to be tested is far from the location of the detection probe and the gas cannot be detected in a timely manner. This improves the detection speed and saves detection time. Attached Figure Description

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0038] Please see Figure 1-11 The present invention provides the following technical solutions:

[0039] Example 1, see Figures 1-11A vacuum environment sealing test device includes an external component 1, a partition component 2, and a test component 3. The external component 1 provides a test fixture platform for the product under test 16, facilitating comprehensive testing of the product 16. The partition component 2 divides the vacuum space within the isolation cover 13 according to the shape and height of the product under test 16, reducing the vacuum area within the isolation cover 13. This allows the test probe 34 to only test the vacuum area where the product under test 16 is located, avoiding large-scale, long-term, and inefficient testing, thus improving testing speed and saving testing time. Furthermore, the test probe 34 can be directionally tested within the divided vacuum area, further improving testing efficiency.

[0040] The function of the detection component 3 is to cover a large area of ​​the surface of the product 16 to be tested according to its shape, so that the detection probe 34 can detect the gas at the leakage point in a timely manner, thereby improving the detection speed and saving detection time.

[0041] Compared to traditional detection probes 34, which are fixed in a position and cannot perform comprehensive and timely detection, the detection component 3, in cooperation with the separation component 2, can adjust the height of the detection probe 34 according to the height of the product under test 16. This allows the detection probe 34 to only detect the vacuum area where the product under test 16 is located, avoiding the problems of large space inside the isolation cover 13 and long gas propagation time, thereby improving detection speed and saving detection time. On the other hand, it can cover a large area of ​​the surface of the product under test 16 according to its shape, allowing the detection probe 34 to detect the gas at the leakage point in a timely manner. This avoids the situation where the leakage point of the product under test 16 is far away from the position of the detection probe 34, and the gas cannot be detected in time, thereby improving detection efficiency.

[0042] See Figure 1 Specifically, the external component 1 includes a support frame 11, a support plate 12 disposed on the top of the support frame 11, an isolation cover 13 disposed on the side of the support plate 12 away from the support frame 11, a vacuum pump 14 disposed on the side of the isolation cover 13, and an air supply tank 15 disposed below the support frame 11.

[0043] The vacuum pump 14 is used to evacuate the space between the isolation cover 13 and the product under test 16, creating a vacuum environment so that the detection probe 34 can detect leaks in the product under test 16. The gas supply tank 15 is used to supply gas to the product under test 16, such as helium. If there is a leak in the product under test 16, helium will spread from the leak point into the vacuum environment, and the detection probe 34 can detect the helium in time.

[0044] See Figures 4-7 Specifically, the partition component 2 is disposed inside the isolation cover 13 and includes a partition plate 21, a micro motor 22 disposed on one side of the partition plate 21, an active bevel gear 23 disposed at the output end of the micro motor 22, a driven bevel gear 24 uniformly disposed in the circumferential direction on the side of the active bevel gear 23 near the micro motor 22, a first rotating rod 25 disposed on the end of the driven bevel gear 24 away from the active bevel gear 23, a leaf blade 26 disposed on the end of the first rotating rod 25 away from the driven bevel gear 24, a second rotating rod 27 disposed on the end of the leaf blade 26 away from the first rotating rod 25, and a lifting component 28 disposed on the circumferential side wall of the partition plate 21.

[0045] In this process, the micro motor 22 starts, driving the active bevel gear 23 to rotate. Since the active bevel gear 23 meshes with the driven bevel gear 24, the rotation of the driven bevel gear 24 drives the first rotating rod 25 to rotate synchronously. The leaf blade 26 and the second rotating rod 27 also rotate accordingly, causing the leaf blade 26 to flip in the middle of the ring of the partition plate 21. When one side of the flipped sidewall of the leaf blade 26 is flush with the horizontal plane, the leaf blades 26 will be flush with each other. During this process, the leaf blades 26 will... As the blades gradually come together, the blades 26 seal the center of the ring of the partition plate 21, thereby dividing the space inside the isolation cover 13. This reduces the size of the vacuum area inside the isolation cover 13, allowing the detection probe 34 to detect only the vacuum area where the product 16 is located, thus avoiding the problems of a large space inside the isolation cover 13 and long gas propagation time, thereby improving detection speed and saving detection time. On the other hand, it allows the detection probe 34 to directionally detect the divided vacuum area, thereby improving detection efficiency.

[0046] See Figure 4 , Figures 10-11 Specifically, the detection component 3 is evenly arranged in the circumferential direction on the side of the partition plate 21 away from the micro motor 22, including a first detection spring 31, a second detection spring 32 disposed at one end of the first detection spring 31, a third detection spring 33 disposed at the end of the second detection spring 32 away from the first detection spring 31, and a detection probe 34 evenly disposed on the same side of the first detection spring 31, the second detection spring 32 and the third detection spring 33.

[0047] The design of the first detection spring 31, the second detection spring 32, and the third detection spring 33, along with their inherent elasticity, allows them to fit tightly against the surface of the product 16 under test. This enables the detection probe 34 to make close contact with the surface of the product 16, allowing it to detect the gas at the venting point promptly. This avoids situations where the venting point of the product 16 is too far from the detection probe 34, preventing timely detection of the gas and thus improving detection speed and saving detection time.

[0048] See Figure 2 and Figure 9 Furthermore, one end of the isolation cover 13 is open and the other end is closed. An annular plate 131 is provided on the outer wall of the isolation cover 13. The annular plate 131 can be flush with the open end of the isolation cover 13. A mating groove 121 is provided on the side wall of the support plate 12 away from the support frame 11. The annular plate 131 can be inserted into the mating groove 121.

[0049] The interlocking engagement between the ring plate 131 and the mating groove 121 fixes the isolation cover 13 and the support plate 12 together, preventing the isolation cover 13 from shaking during the vacuuming process and thus improving stability.

[0050] See Figures 1-4 Furthermore, the mating groove 121 also contains a product 16. The bottom of the mating groove 121 has an input hole 122 that can penetrate the side wall of the support plate 12. A sealing ring 123 is provided inside the input hole 122, and a gas supply hose 124 is provided inside the sealing ring 123. One end of the gas supply hose 124 can be connected to the input end of the product 16, and the other end can be connected to the output end of the gas supply tank 15. An output pipe 132 is provided on the side wall of the closed end of the isolation cover 13. One end of the output pipe 132 can be connected to the isolation cover 13, and the other end is provided with a vacuum hose 133. The end of the vacuum hose 133 away from the output pipe 132 can be connected to the input end of the vacuum pump 14.

[0051] The vacuum pump 14 is started, which delivers the air in the isolation cover 13 to the vacuum hose 133 through the output pipe 132. The air enters the vacuum pump 14 through the vacuum hose 133 and is then extracted, thus creating a vacuum state inside the isolation cover 13. Subsequently, the vacuum pump 14 is stopped, and the gas supply tank 15 is started, which delivers gas to the gas supply hose 124. The gas spreads along the gas supply hose 124 into the product under test 16, filling the interior of the product under test 16, thereby achieving the purpose of testing the sealing performance of the surface of the product under test 16.

[0052] Because a sealing ring 123 is provided inside the input port 122, outside air is prevented from entering the vacuum environment inside the isolation cover 13, thus ensuring airtightness.

[0053] See Figures 4-7 Furthermore, the partition plate 21 is annular, and a partition post 29 is provided in the middle of the inner ring of the partition plate 21. Extension strips 291 are evenly provided on the outer wall of the partition post 29. The extension strips 291 can be flush with one end of the partition post 29, and the end of the extension strip 291 away from the partition post 29 can be connected to the inner wall of the partition plate 21.

[0054] The partition column 29 and the extension strip 291 work together to provide support for the partition column 29, so that the partition column 29 is located in the center of the ring of the partition plate 21, thereby making the sheet 26 evenly distributed around the partition column 29.

[0055] See Figures 4-7 Furthermore, the end of the separator 29 away from the extension strip 291 is provided with a rotating groove 292. The driving bevel gear 23 is located in the rotating groove 292. A rotating shaft 231 is provided in the center hole of the driving bevel gear 23. One end of the rotating shaft 231 can be connected to the output end of the micro motor 22, and the other end can be rotatably connected to the bottom of the rotating groove 292. The driving bevel gear 23 can mesh with the driven bevel gear 24 for transmission.

[0056] The outer wall of the partition column 29 is uniformly provided with rotating holes 293. The rotating holes 293 can penetrate the side wall of the partition column 29 and communicate with the rotating groove 292. The end of the first rotating rod 25 away from the blade 26 can be connected to the end of the driven bevel gear 24 away from the driving bevel gear 23 through the rotating holes 293. The blade 26 is fan-shaped and can be evenly distributed in the circumferential direction within the inner ring of the partition plate 21. The blades 26 can fit tightly against each other. The end of the second rotating rod 27 away from the blade 26 can be rotatably connected to the inner ring wall of the partition plate 21.

[0057] The design of the rotating groove 292 provides rotational space for the driving bevel gear 23 and the driven bevel gear 24. When the driven bevel gear 24 rotates, it drives the first rotating rod 25 to rotate within the rotating groove 292, thereby driving the blades 26 and the second rotating rod 27 to rotate synchronously. Since the blades 26 are fan-shaped, they gradually come together tightly during the flipping process until they are flush with each other, so that the blades 26 close the middle of the ring of the partition plate 21. This allows the partition plate 21 to divide the space inside the isolation cover 13. On the one hand, this reduces the space of the vacuum area inside the isolation cover 13, so the detection probe 34 only needs to detect the vacuum area where the product to be tested 16 is located, avoiding the problems of a large space inside the isolation cover 13 and long gas propagation time, thereby improving the detection speed and saving detection time. On the other hand, it allows the detection probe 34 to detect the divided vacuum area in a specific direction, thereby improving the detection efficiency.

[0058] Example 2, see Figures 8-9 Furthermore, the lifting component 28 includes a lifting motor 281, a lead screw 282 disposed at the output end of the lifting motor 281, and a moving block 283 sleeved on the lead screw 282; the lifting motor 281 is located on the side of the support plate 12 near the support frame 11, and a suspension plate 17 is disposed in the middle of the side wall of the support plate 12 near the support frame 11, and the side wall of the suspension plate 17 can be connected to the bottom of the lifting motor 281.

[0059] A movable groove 134 is provided on the inner wall of the isolation cover 13. The movable groove 134 can extend and be distributed along the height direction of the isolation cover 13. The lead screw 282 is distributed in the movable groove 134. One end of the lead screw 282 can be rotatably connected to the top of the inner wall of the isolation cover, and the other end can pass through the side wall of the support plate 12 and be connected to the output end of the lifting motor 281. A sealing ring 135 is provided at the penetration point between the lead screw 282 and the support plate 12. The movable block 283 can slide in the movable groove 134. The side wall of the movable block 283 can be connected to the outer ring wall of the partition plate 21.

[0060] When it is necessary to adjust the height between the partition plate 21 and the product under test 16, the lifting motor 281 is started, driving the lead screw 282 to rotate within the moving groove 134. This causes the moving block 283, which is connected to the threaded groove on the surface of the lead screw 282, to move up and down within the lead screw 282. Consequently, the partition plate 21, which is connected to the moving block 283, moves up and down synchronously, bringing the partition plate 21 closer to the top of the product under test 16. On the one hand, the partition plate 21 separates the vacuum area where the product under test 16 is located from other vacuum areas, making the vacuum area to be detected smaller. The detection probe 34 only needs to detect the vacuum area where the product under test 16 is located, avoiding the problems of a large space inside the isolation cover 13 and a long gas propagation time, thereby improving the detection speed and saving detection time. On the other hand, it allows the detection probe 34 to perform directional detection on the separated vacuum area, thereby improving the detection efficiency.

[0061] See Figures 8-9 Furthermore, the inner wall of the isolation cover 13 is provided with sliding grooves 136. There are three sliding grooves 136. One sliding groove 136 is arranged opposite to the moving groove 134. The other two sliding grooves 136 are arranged opposite to each other and are perpendicular to the moving groove 134. The sliding grooves 136 can extend along the height direction of the isolation cover 13. A sliding block 137 is provided in the sliding groove 136. The side wall of the sliding block 137 away from the sliding groove 136 can be connected to the outer ring wall of the partition plate 21.

[0062] During the up-and-down movement of the partition plate 21, since the three sliding blocks 137 are all connected to the partition plate 21, the three sliding blocks 137 will slide synchronously in the three sliding grooves 136, which reduces the friction force of the partition plate 21 during movement and achieves the purpose of sliding displacement and guidance.

[0063] Example 3, see Figures 10-11 Furthermore, the first detection spring 31 is arc-shaped. One side of the first detection spring 31 can be connected to the side wall of the partition plate 21 away from the micro motor 22, and the other end is provided with a first flip hole 311. A first flip rod 312 is provided in the first flip hole 311. A first torsion spring 313 is sleeved on the first flip rod 312. Both ends of the first torsion spring 313 can be connected to the inner wall of the first flip hole 311. One end of the first flip rod 312 can be rotatably connected to one side of the second detection spring 32.

[0064] The second detection spring 32 has a second flip hole 321 at the end away from the first flip rod 312. A second flip rod 322 is provided in the second flip hole 321. A second torsion spring 323 is sleeved on the second flip rod 322. The two ends of the second torsion spring 323 can be connected to the inner wall of the second flip hole 321. One end of the second flip rod 322 can be rotatably connected to one side of the third detection spring 33.

[0065] During the process of the partition plate 21 moving towards the product 16 to be tested, since the first detection spring 31 is arc-shaped, the convex surface of the first detection spring 31 will first contact the surface of the product 16 to be tested. The detection probe 34 is located on one side of the convex surface of the first detection spring 31, so that the detection probe 34 can perform a sealing test on the surface of the product 16 to be tested. This avoids the situation where the gas leakage point of the product 16 to be tested is far away from the position of the detection probe 34, and the gas cannot be detected in time, thereby improving the detection speed and saving detection time.

[0066] If the product to be tested 16 has a wide horizontal volume, the partition plate 21 will push the first detection spring 31 outward during the downward movement. The first detection spring 31 will deform due to its elasticity, so that the first detection spring 31 will gradually expand outward to adapt to the detection of products 16 with different widths, thereby improving practicality.

[0067] When the product under test 16 is pressed outward against the second detection spring 32 in the width direction, it will drive the first flipping rod 312 in the first flipping hole 311 to rotate. The first torsion spring 313 undergoes elastic deformation, and the second detection spring 32 will also deform due to its own elasticity. This allows the side of the second detection spring 32 closest to the detection probe 34 to fit tightly against the surface of the product under test 16, so that the detection probe 34 can perform a sealing test on the surface of the product under test 16. This avoids the situation where the gas leakage point of the product under test 16 is far away from the location of the detection probe 34, and the gas cannot be detected in time, thereby improving the detection speed and saving detection time.

[0068] If the force exerted by the product under test 16 on the second detection spring 32 disappears, the first torsion spring 313 will restore its deformation and bounce the second detection spring 32 back to its free state.

[0069] When the product under test 16 presses the third detection spring 33 outward, it will drive the second flipping rod 322 in the second flipping hole 321 to rotate. The second torsion spring 323 undergoes elastic deformation, and the third detection spring 33 will also deform due to its own elasticity. This allows the side of the third detection spring 33 closest to the detection probe 34 to fit tightly against the surface of the product under test 16, so that the detection probe 34 can perform a sealing test on the surface of the product under test 16. This avoids the situation where the gas leakage point of the product under test 16 is far away from the location of the detection probe 34, and the gas cannot be detected in time, thereby improving the detection speed and saving detection time.

[0070] If the force exerted by the product under test 16 on the third detection spring 33 disappears, the second torsion spring 323 will restore its deformation and bounce the third detection spring 33 back to its free state.

[0071] See Figures 10-11 Furthermore, detection grooves 35 are provided on the sidewalls of the first detection spring 31, the second detection spring 32, and the third detection spring 33 on the same side. The detection grooves 35 are evenly distributed along the length of the first detection spring 31, the second detection spring 32, and the third detection spring 33. The detection probe 34 is located in the detection groove 35. Anti-collision blocks 36 are provided on the protruding sidewalls between the detection grooves 35.

[0072] The design of the detection groove 35 and the detection probe 34 avoids damage to the detection probe 34 during the bonding process of the first detection spring 31, the second detection spring 32, and the third detection spring 33 to the product under test 16, thereby improving the service life of the detection probe 34. The anti-collision block 36 prevents damage to the surface of the product under test 16 when the first detection spring 31, the second detection spring 32, and the third detection spring 33 are bonded to the product under test 16, thus ensuring the integrity of the product under test 16.

[0073] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
