Description

Technical Field

[0001] This invention relates to the field of leakage detection technology, specifically to a leakage detection device and method for an inverted electronic-grade isopropanol container. Background Technology

[0002] In industrial applications, isopropanol is widely used as a solvent, particularly in the pharmaceutical, cosmetic, plastics, fragrance, and coating industries. It can dissolve a variety of organic substances, such as cellulose, rubber, and resins, and is miscible with water, ethanol, ether, and chloroform. Furthermore, isopropanol is also used in cleaning agents, disinfectants, and cleaning agents in the electronics industry.

[0003] Isopropanol is a colorless, transparent liquid with an odor reminiscent of alcohol and acetone. It is flammable, highly volatile, and somewhat toxic. Long-term exposure may lead to health problems such as skin allergies, headaches, dizziness, and incoordination. Therefore, in routine storage, the sealing of storage containers is crucial to prevent leakage. Leakage detection is an essential part of the production of isopropanol storage containers.

[0004] Existing leak detection devices typically involve inverting the container to be tested and observing for leaks. However, this method does not take into account the stability of the connection between the sealing plug and the container, which can lead to inaccurate test results. Furthermore, the fact that the sealing plug remains in the same position on the container makes it impossible to guarantee the comprehensiveness of the detection. Summary of the Invention

[0005] The purpose of this invention is to provide a leakage detection device and method for an inverted electronic-grade isopropanol container, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A leakage detection device for an inverted electronic-grade isopropanol container, including a support, and further comprising:

[0008] The movable plate is movably mounted on the support. The movable plate can be driven by a lateral drive component mounted on the support to move along the length direction of the support. Two sets of telescopic arms are installed on the movable plate, and the telescopic arms have stored elastic potential energy.

[0009] A cylinder, mounted on the movable plate, is used to support the container to be inspected. The cylinder is equipped with a fastening mechanism for fixing the container to be inspected. The cylinder is located between the two sets of telescopic arms and is connected to a flipping mechanism. The flipping mechanism is triggered when the movable plate moves along the length direction of the support to the latter part of its stroke, and can drive the cylinder to flip so that the container inside the cylinder changes from an upright state to an inverted state, thus completing one inspection of the container.

[0010] A guiding mechanism is provided on the support and cooperates with the two sets of telescopic arm groups. When the movable plate moves to one side, the guiding mechanism can cause the telescopic arm groups to release and store elastic potential energy multiple times. When the telescopic arm groups release elastic potential energy, they can drive the cylinder to bounce upward so that the liquid in the container to be tested impacts the sealing plug.

[0011] An orientation adjustment mechanism is provided on the support. The orientation adjustment mechanism can move to the top of the cylinder and perform a screwing action on the sealing plug on the container to be inspected, so as to change the orientation of the sealing plug in the container to be inspected, so as to enter the secondary inspection of the container.

[0012] As a further embodiment of the present invention: the telescopic arm assembly includes a guide arm fixedly installed on the movable plate and a telescopic arm slidably fitted with the guide arm, and a rotating shaft is rotatably installed at the end of each of the two telescopic arms away from the movable plate;

[0013] The cylinder is positioned between the two rotating shafts, one of which is connected to the flipping mechanism. Two sets of elastic energy storage structures are connected between the guide arm and the telescopic arm.

[0014] As a further embodiment of the present invention: the elastic energy storage structure includes a column disposed on the side of the guide arm via a protrusion and a first cylindrical spring sleeved on the outer periphery of the column. The column is provided with a lug through the side of the telescopic arm and the lug is slidably connected to the column. The side of the guide arm is provided with a through groove for the lug to move. The two ends of the first cylindrical spring are respectively connected to the lug and the protrusion.

[0015] As a further embodiment of the present invention: the guiding mechanism includes a limiting plate disposed on the side of the support, a connecting arm disposed between the two telescopic arms, a column fixedly disposed on the side of the connecting arm away from the cylinder, a groove disposed on the limiting plate that cooperates with the column, the column extending into the groove and slidingly connected with the limiting plate.

[0016] As a further embodiment of the present invention: the trough body includes a first horizontal trough, a plurality of trapezoidal troughs, a vertical trough, a third horizontal trough and an inclined trough connected together, the inclined trough being connected to the middle part of the first horizontal trough, and the connection between the vertical trough and the third horizontal trough being connected to a second horizontal trough.

[0017] The trapezoidal groove includes a connected vertical section, a horizontal section, and an inclined section. A first sway bar and a second sway bar are rotatably provided on the limiting plate. The rotation shafts of the first sway bar and the second sway bar are both connected to torsion springs. They are located at the end of the vertical groove facing the third horizontal groove and the end of the inclined groove away from the third horizontal groove, respectively.

[0018] As a further embodiment of the present invention: the flipping mechanism includes a cooperating elastic transmission structure disposed on the side of the guide arm and a rod-belt connection structure connecting the elastic transmission structure and the rotating shaft, and a vertical arm is fixedly disposed on the support, the vertical arm cooperating with the elastic transmission structure.

[0019] As a further embodiment of the present invention: the elastic transmission structure includes a driven shaft rotatably mounted on the side of the guide arm and a drive tube that is slidably sleeved with the driven shaft and cooperates with the vertical arm. The drive tube is provided with a protrusion, and the outer wall of the driven shaft is provided with a groove adapted to the protrusion. The protrusion extends into the groove and is slidably connected to the driven shaft. The groove is spirally arranged.

[0020] The guide arm is provided with a crossbar on its side. The crossbar is slidably connected to a protrusion formed on the outer wall of the drive tube. The outer periphery of the crossbar is fitted with a second cylindrical spring with its two ends respectively connected to the protrusion and the guide arm.

[0021] As a further embodiment of the present invention: the rod-belt connection structure includes a first tilting arm and a second tilting arm whose ends are rotatably connected by a shaft. The tail end of the first tilting arm is rotatably connected to the rotating shaft, and the tail end of the second tilting arm is rotatably connected to the driven shaft. The shaft is also connected to the rotating shaft and the driven shaft respectively through a first transmission belt and a second transmission belt.

[0022] As a further embodiment of the present invention: the support is provided with two horizontal arms, and a sliding arm is slidably sleeved on each of the two horizontal arms. The orientation adjustment mechanism includes an assembly table disposed between the two sliding arms and a turntable rotatably disposed on the assembly table. A drive motor is mounted on the assembly table, and a drive gear is fixedly connected to the output shaft of the drive motor. The drive gear meshes with a gear ring disposed on the turntable.

[0023] The sliding arm can be driven by an external horizontal drive to slide on the horizontal arm. A second double-headed electric push rod is also installed at the bottom of the turntable. Each of the two movable ends of the second double-headed electric push rod is provided with a fastener, and the fastener is arranged in an arc shape.

[0024] The method for detecting leakage in an isopropanol container using the aforementioned leakage detection device includes the following steps:

[0025] Step 1: Place the container to be inspected upright inside the cylinder, and use the fastening mechanism to secure the container inside the cylinder.

[0026] Step two: The movable plate moves along the length of the support, and the telescopic arm assembly releases and stores elastic potential energy multiple times, causing the liquid in the container to impact the sealing plug multiple times.

[0027] Step 3: The flipping mechanism is triggered, driving the cylinder to flip the container under test. The container under test changes from an upright state to an inverted state. The container is inverted for 5-10 minutes. Check whether there is any leakage at the sealing plug of the container to complete one test.

[0028] Step four: The movable plate is reset, the orientation adjustment mechanism is activated, and the sealing plug on the container is screwed to change its orientation before proceeding to the second inspection.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] During testing, the movable plate moves to one side along the length of the support. During this process, the guiding mechanism causes the telescopic arm assembly to release and store elastic potential energy multiple times. When the telescopic arm assembly releases elastic potential energy, it will cause the cylinder to spring upwards instantly. As a result, after the container under test stops rising, the liquid inside will impact the sealing plug due to inertia. This takes into account the stability of the connection between the sealing plug and the container, ensuring the accuracy of the test results.

[0031] Secondly, the entire testing process is carried out in multiple stages. Starting from the second test, the positioning adjustment mechanism screws the sealing plug on the container before the test to prevent the position of the sealing plug from remaining unchanged during the test. This allows for multiple tests to be conducted based on the different positions of the sealing plug, improving the comprehensiveness and effectiveness of the test. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Furthermore, elements in this invention are referred to as being "disposed on" or "located on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0046] Please see Figures 1-11 In this embodiment of the invention, the leakage detection device for an inverted electronic-grade isopropanol container includes a support 1, and further includes:

[0047] The movable plate 2 is movably mounted on the support 1. The movable plate 2 can be driven by the transverse drive member mounted on the support 1 to move along the length direction of the support 1. The movable plate 2 is equipped with two sets of telescopic arms arranged opposite to each other, and the telescopic arms have stored elastic potential energy.

[0048] A cylinder 3, mounted on the movable plate 2, is used to support the container to be inspected. A fastening mechanism for fixing the container to be inspected is installed on the cylinder 3. The cylinder 3 is located between the two sets of telescopic arms and is connected to a flipping mechanism. The flipping mechanism is triggered when the movable plate 2 moves along the length direction of the support 1 to the latter part of the stroke, and can drive the cylinder 3 to flip so that the container inside the cylinder 3 changes from an upright state to an inverted state, completing one inspection of the container.

[0049] A guiding mechanism is provided on the support 1 and cooperates with the two sets of telescopic arm groups. When the movable plate 2 moves to one side, the guiding mechanism can cause the telescopic arm group to release and store elastic potential energy multiple times. When the telescopic arm group releases elastic potential energy, it can drive the cylinder 3 to bounce upward so that the liquid in the container to be tested impacts the sealing plug.

[0050] An orientation adjustment mechanism is provided on the support 1. The orientation adjustment mechanism can move to the top of the cylinder 3 and perform a screwing action on the sealing plug on the container to be inspected, so as to change the orientation of the sealing plug in the container to be inspected, so as to enter the secondary inspection of the container.

[0051] The following points require further explanation (see reference). Figure 6 and Figure 7 The fastening mechanism includes a first double-headed electric push rod 4 installed at the bottom of the cylinder 3 and arranged radially along the cylinder 3, two connecting columns 301 slidably disposed on the cylinder 3, and two clamping members 5 respectively disposed on the two connecting columns 301. The clamping members 5 are arranged in an arc shape, and the movable end of the first double-headed electric push rod 4 is fixedly connected to the two connecting columns 301 respectively. In use, a certain amount of liquid is first filled into the container to be inspected (filled to half full), and the container to be inspected is placed in the cylinder 3. Then, the first double-headed electric push rod 4 is turned on. The first double-headed electric push rod 4 drives the two connecting columns 301 to move the two clamping members 5 closer to each other along the radial direction of the cylinder 3. Thus, the two clamping members 5 can clamp and fix the container to be inspected, ensuring that the container to be inspected can remain stable in the cylinder 3 during the inspection process.

[0052] Secondly, the transverse drive component (labeled in the figure) includes a lead screw rotatably mounted on the support 1 and a guide rod disposed on the support 1. A drive motor is also mounted on the support 1. The output end of the drive motor is connected to the lead screw, and the lead screw and the guide rod pass through the movable plate 2. The movable plate 2 is threadedly connected to the lead screw and slidably connected to the guide rod. The drive motor is a servo motor whose output end can drive bidirectionally. During detection, the drive motor drives the lead screw to rotate in the forward or reverse direction, which enables the movable plate 2 to move back and forth twice along the length direction of the support 1, performing the first and second detections of the container.

[0053] Specifically, during operation, after the container to be inspected is placed and fixed, the movable plate 2 moves to one side along the length of the support 1. During this process, the guiding mechanism causes the telescopic arm assembly to release and store elastic potential energy multiple times. When the telescopic arm assembly releases elastic potential energy, it will cause the cylinder 3 to spring upward instantly. Then, after the container to be inspected stops rising, the liquid inside will impact the sealing plug due to inertia. After multiple impacts, the movable plate 2 enters the next stroke. During this process, the flipping mechanism is triggered, driving the cylinder 3 to flip half a turn. Then, the container to be inspected changes from an upright state to an inverted state. It is observed whether there is leakage at the sealing plug. (It should be noted that in actual testing, it may be difficult to determine whether there is leakage by visual observation. In this regard, the device can be equipped with a corresponding enclosed shell, and a sensor can be set inside the shell, i.e., at the inverted point of the container. The high sensitivity of the sensor can be used to determine whether there is leakage. Specific measures can be adapted according to actual needs. This application will not elaborate on this.)

[0054] Subsequently, the active panel 2 returns to its reset state, completing one detection process. If the first detection process passes, the orientation adjustment mechanism operates before the second detection process, rotating the sealing plug on the container to be inspected, and then performing the second detection (and so on, with subsequent three, four, etc. detections possible). Therefore, the orientation adjustment mechanism can change the orientation of the sealing plug on the container, allowing for multiple detections based on the sealing plug's different orientations, thus improving the comprehensiveness and effectiveness of the detection.

[0055] Please refer to it again. Figure 8 The telescopic arm assembly includes a guide arm 6 fixedly mounted on the movable plate 2 and a telescopic arm 7 slidably fitted with the guide arm 6. A rotating shaft 12 is rotatably mounted at the end of each of the two telescopic arms 7 away from the movable plate 2. The cylinder 3 is positioned between the two rotating shafts 12, and one of the rotating shafts 12 is connected to the flipping mechanism. Two sets of elastic energy storage structures are connected between the guide arm 6 and the telescopic arm 7.

[0056] Furthermore, the guiding mechanism is designed to control the sliding of the telescopic arm 7 within the guide arm 6. When the telescopic arm 7 slides upward within the guide arm 6, both telescopic arms 7 can drive the cylinder 3 and the container to be inspected inside the cylinder 3 to rise. The flipping mechanism is designed to trigger during the latter part of the movement of the movable plate 2, causing the rotating shaft 12 to rotate half a turn, thereby causing the rotating shaft 12 to invert the cylinder 3, switching the container to be inspected inside the cylinder 3 from an upright state to an inverted state, so as to facilitate the determination of leakage.

[0057] The elastic energy storage structure includes a column 8 disposed on the side of the guide arm 6 via a protrusion 601 and a first cylindrical spring 9 sleeved on the outer periphery of the column 8. The column 8 passes through a lug 10 disposed on the side of the telescopic arm 7, and the lug 10 is slidably connected to the column 8. The side of the guide arm 6 is provided with a through groove 602 for the lug 10 to move. The two ends of the first cylindrical spring 9 are respectively connected to the lug 10 and the protrusion 601. The guiding mechanism includes a limiting plate 23 disposed on the side of the support 1. A connecting arm 21 is disposed between the two telescopic arms 7. A column 22 is fixedly disposed on the side of the connecting arm 21 away from the cylinder 3. The limiting plate 23 is provided with a groove that cooperates with the column 22. The column 22 extends into the groove and is slidably connected to the limiting plate 23. The groove body includes a first horizontal groove 2301, multiple trapezoidal grooves, a vertical groove 2305, a third horizontal groove 2307, and an inclined groove 2308 connected together. The inclined groove 2308 connects to the middle of the first horizontal groove 2301. The connection between the vertical groove 2305 and the third horizontal groove 2307 is also connected to a second horizontal groove 2306. The trapezoidal groove includes a vertical section 2302, a horizontal section 2303, and an inclined section 2304 connected together. A first deflector 24 and a second deflector 25 are rotatably provided on the limiting plate 23. The rotation shafts of the first deflector 24 and the second deflector 25 are both connected to torsion springs. They are located at the end of the vertical groove 2305 facing the third horizontal groove 2307 and the end of the inclined groove 2308 away from the third horizontal groove 2307, respectively.

[0058] Initially, the column 22 is located at the end of the first horizontal groove 2301 away from the trapezoidal groove, and the first column spring 9 is in a compressed state. As the movable plate 2 moves, when the column 22 moves to the intersection of the first horizontal groove 2301 and the vertical section 2302 (the second deflector 25 acts as a blocking element), the first column spring 9 rebounds instantaneously, the telescopic arm 7 instantly lifts within the guide arm 6, and the column 22 moves into the horizontal section 2303. The liquid in the container to be inspected then impacts the sealing plug under inertia. Subsequently, the column 22 makes way through the inclined section 2304, the telescopic arm 7 descends toward the guide arm 6, the first column spring 9 is compressed again, and after passing through multiple trapezoidal grooves, the sealing plug on the container to be inspected is subjected to multiple impacts from the internal liquid. Finally, the column 22 enters the vertical groove 2305, and the sealing plug is subjected to a final impact. At this time, the column 22 will cause the first deflector 24 to deflect toward the third horizontal groove 2307, and then move toward the second horizontal groove 2306. During this process, the flipping mechanism is triggered, causing the container to be inspected to be inverted.

[0059] Preferably, the container to be tested is kept inverted for 5-10 minutes;

[0060] Subsequently, the movable plate 2 moves in the reverse direction to reset. During this process, the first deflector 24 acts as a blocking element, and the column 22 moves along the second horizontal groove 2306 and the third horizontal groove 2307. When the column 22 enters the inclined groove 2308, the column 22 gives way, and the telescopic arm 7 gradually retracts into the guide arm 6. The first column spring 9 is compressed. Finally, the column 22 causes the second deflector 25 to deflect towards the first horizontal groove 2301, and the column 22 resets to the initial position (i.e., the end of the first horizontal groove 2301 away from the trapezoidal groove).

[0061] It should also be noted that after the column 22 enters the vertical section 2302 and the vertical groove 2305, although the first column spring 9 rebounds quickly, it still requires a certain amount of time. At this time, in order to ensure that the first column spring 9 rebounds smoothly and to ensure the effectiveness of the impact treatment of the liquid in the container under test on the sealing plug, the transverse drive needs to be stopped. However, there are multiple impact processes during the test, and the transverse drive needs to be stopped multiple times. In this way, when the braking system fails, it is easy to cause damage to the column 22 or other components. To address this, the vertical section 2302 and the vertical groove 2305 have been widened to ensure that the first column spring 9 can rebound smoothly and without error without stopping the transverse drive.

[0062] Please refer to it again. Figure 2 , Figure 5 as well as Figure 8 The flipping mechanism includes an elastic transmission structure located on the side of the guide arm 6 and a rod-belt connection structure connecting the elastic transmission structure and the rotating shaft 12. A vertical arm 101 is fixedly mounted on the support 1, and the vertical arm 101 cooperates with the elastic transmission structure. The elastic transmission structure includes a driven shaft 11 rotatably mounted on the side of the guide arm 6 and a drive tube 18 that slides with the driven shaft 11 and cooperates with the vertical arm 101. A protrusion 1801 is provided on the drive tube 18, and a groove 1101 adapted to the protrusion 1801 is provided on the outer wall of the driven shaft 11. The protrusion 1801 extends into the groove 1101 and is slidably connected to the driven shaft 11. The groove 1101 is spirally arranged. The guide arm 6 is also provided with a crossbar 19 on its side. The crossbar 19 is slidably connected to the protrusion 1802 formed on the outer wall of the drive tube 18, and the outer periphery of the crossbar 19 is fitted with a second columnar spring 20, the two ends of which are respectively connected to the protrusion 1802 and the guide arm 6.

[0063] As the column 22 moves away from the third horizontal groove 2307 in the second horizontal groove 2306, the drive tube 18 and the upright arm 101 are in contact, the drive tube 18 and the upright arm 101 remain relatively stationary, the driven shaft 11 slides relative to the drive tube 18, the second columnar spring 20 is compressed, and the protrusion 1801 slides with the driven shaft 11 through the groove 1101, thereby causing the driven shaft 11 to rotate. Then, the driven shaft 11 will drive the rotating shaft 12 to rotate half a turn through the rod connection structure, causing the cylinder 3 to invert the container to be inspected inside it.

[0064] During the initial stroke of the moving plate 2 returning to its reset position, the second cylindrical spring 20 gradually rebounds, and the protruding post 1801 slides with the driven shaft 11 again through the groove 1101, causing the driven shaft 11 to drive the rotating shaft 12 to rotate in the opposite direction through the rod-belt connection structure, and the cylinder 3 drives the container inside it to return to an upright state.

[0065] The rod-belt connection structure includes a first tilting arm 14 and a second tilting arm 15 whose heads are rotatably connected by a shaft 13. The tail end of the first tilting arm 14 is rotatably connected to the rotating shaft 12, and the tail end of the second tilting arm 15 is rotatably connected to the driven shaft 11. The shaft 13 is also connected to the rotating shaft 12 and the driven shaft 11 by a first transmission belt 16 and a second transmission belt 17, respectively.

[0066] During the lifting and lowering process of the telescopic arm 7, the distance between the rotating shaft 12 and the driven shaft 11 changes, and correspondingly, the included angle between the first tilting arm 14 and the second tilting arm 15 changes. When the driven shaft 11 rotates, it will drive the rotating shaft 12 to rotate through the second transmission belt 17, the shaft 13 and the first transmission belt 16, so as to realize the transmission function when the distance between the driven shaft 11 and the rotating shaft 12 is not fixed.

[0067] The Figure 1 , Figure 10 as well as Figure 11 The support 1 has two horizontal arms 26, and each of the two horizontal arms 26 has a sliding arm 27 slidably mounted on it. The orientation adjustment mechanism includes an assembly platform 28 disposed between the two sliding arms 27 and a turntable 29 rotatably mounted on the assembly platform 28. A drive motor 33 is mounted on the assembly platform 28, and the output shaft of the drive motor 33 is fixedly connected to a drive gear 34. The drive gear 34 meshes with a gear ring 32 disposed on the turntable 29. The sliding arm 27 can be driven by an external horizontal drive component to slide on the horizontal arm 26. A second double-headed electric push rod 30 is also mounted on the bottom of the turntable 29. Each of the two movable ends of the second double-headed electric push rod 30 is provided with a fastener 31, which is arc-shaped.

[0068] Each time the movable plate 2 is reset and the container passes through the previous detection process, the external horizontal drive (selectable as a cylinder or hydraulic cylinder) drives the sliding arm 27 to slide on the horizontal arm 26, so that the two fasteners 31 reach both sides of the container sealing plug. Then, the second double-headed electric push rod 30 drives the two fasteners 31 to move closer to each other, clamping the container sealing plug. Then, the drive motor 33 drives the drive gear 34 to rotate, and the drive gear 34 can drive the turntable 29 to rotate through the gear ring 32. Thus, the sealing plug on the container can be twisted at a certain angle, which can change the position of the sealing plug on the container. Multiple detections can be performed for the sealing plug in different positions, improving the comprehensiveness and detection effect of the detection.

[0069] It should be added that, since the shape of the sealing plugs provided with different containers to be inspected may vary, the fastener 31 is designed to be replaceable.

[0070] As another embodiment of the present invention, a method for detecting leakage in an isopropanol container using the aforementioned leakage detection device is also proposed, comprising the following steps:

[0071] Step 1: Place the container to be inspected upright inside the cylinder 3, and use the fastening mechanism to set the container to be inspected inside the cylinder 3;

[0072] Step 2: The movable plate 2 moves along the length of the support 1, and the telescopic arm assembly releases and stores elastic potential energy multiple times, causing the liquid in the container to impact the sealing plug multiple times.

[0073] Step 3: The flipping mechanism is triggered, driving cylinder 3 to flip the container under test. The container under test is switched from the upright state to the inverted state. The container is inverted for 5-10 minutes. Check whether there is any leakage at the sealing plug of the container to complete one test.
