Description

Technical Field

[0001] The present invention relates to the technical field of liquid leakage detection, and specifically to a liquid leakage detection device for an inverted electronic-grade isopropyl alcohol container and a detection method thereof. Background Art

[0002] In industrial applications, isopropyl alcohol is widely used as a solvent, especially in industries such as pharmaceuticals, cosmetics, plastics, fragrances, and coatings. It can dissolve a variety of organic substances, such as cellulose, rubber, resin, etc., and can be miscible with water, ethanol, ether, chloroform, etc. In addition, isopropyl alcohol is also used in cleaners, disinfectants, and cleaning agents in the electronics industry.

[0003] Isopropyl alcohol is a colorless and transparent liquid with an odor of a mixture of alcohol and acetone. It is flammable, highly volatile, and has certain toxicity. Long-term exposure may cause skin allergic reactions, headaches, dizziness, coordination disorders and other health problems. Therefore, in daily storage, the sealing performance of the storage container is required to be relatively high to avoid liquid leakage. In the production of isopropyl alcohol storage containers, liquid leakage detection is an essential task.

[0004] Existing liquid leakage detection devices usually directly invert the container to be inspected and then observe whether there is liquid leakage. In this regard, the stability of the connection between the sealing plug and the container is not taken into consideration, resulting in deviation of the detection results. Moreover, the orientation of the sealing plug on the container remains unchanged all the time, and the comprehensiveness of the detection cannot be guaranteed. Summary of the Invention

[0005] The purpose of the present invention is to provide a liquid leakage detection device for an inverted electronic-grade isopropyl alcohol container and a detection method thereof to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A liquid leakage detection device for an inverted electronic-grade isopropyl alcohol container, including a support, and further including: A movable plate, movably arranged on the support. The movable plate can be driven by a transverse movement driving member arranged on the support to move along the length direction of the support. Two sets of relatively arranged telescopic arm groups are installed on the movable plate, and the telescopic arm groups store elastic potential energy; A cylinder, arranged on the movable plate for receiving the container to be inspected. A fastening mechanism for fixing the container to be inspected is installed on the cylinder. The cylinder is located between the two sets of telescopic arm groups and is connected with a flipping mechanism. The flipping mechanism is triggered when the movable plate moves to the latter part of the stroke along the length direction of the support and can drive the cylinder to flip, so that the container in the cylinder is switched from an upright state to an inverted state, completing one detection of the container; The guiding mechanism is arranged on the support and cooperates with the two telescopic arm groups. When the movable plate moves towards one side, the guiding mechanism can prompt 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 eject upward, so that the liquid contained in the container to be inspected impacts the sealing plug. The orientation adjustment mechanism is arranged on the support. The orientation adjustment mechanism can move above 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 and enter the secondary inspection of the container.

[0007] As a further solution of the present invention: the telescopic arm group includes a guiding arm fixedly installed on the movable plate and a telescopic arm slidably sleeved with the guiding arm. One rotating shaft is respectively rotatably installed at one end of the two telescopic arms away from the movable plate. Wherein, the cylinder is arranged between the two rotating shafts, and one of the rotating shafts is connected to the flipping mechanism. Two elastic energy storage structures are connected between the guiding arm and the telescopic arm.

[0008] As a further solution of the present invention: the elastic energy storage structure includes a column arranged on the side of the guiding arm through a protruding block and a first cylindrical spring sleeved on the outer periphery of the column. The column penetrates through a lug on the side of the telescopic arm, and the lug is slidably connected to the column. A through groove for the movement of the lug is arranged on the side of the guiding arm. The two ends of the first cylindrical spring are respectively connected to the lug and the protruding block.

[0009] As a further solution of the present invention: the guiding mechanism includes a limiting plate arranged on the side of the support. A connecting arm is arranged between the two telescopic arms. A column is fixedly arranged on the side of the connecting arm away from the cylinder. A groove body matched with the column is arranged on the limiting plate. The column extends into the groove body and is slidably connected to the limiting plate.

[0010] As a further solution of the present invention: the groove body includes a connected first horizontal groove, a plurality of trapezoidal grooves, a vertical groove, a third horizontal groove and an inclined groove. The inclined groove communicates with the middle of the first horizontal groove. A second horizontal groove is also communicated at the connection of the vertical groove and the third horizontal groove. Wherein, the trapezoidal groove includes a connected vertical section, a horizontal section and an inclined section. A first deflecting member and a second deflecting member are rotatably arranged on the limiting plate. The rotating shafts of the first deflecting member and the second deflecting member are both connected with torsion springs, and they are respectively located at one end of the vertical groove facing the third horizontal groove and one end of the inclined groove away from the third horizontal groove.

[0011] As a further solution of the present invention: the flipping mechanism includes a matching elastic transmission structure provided on the side of the guiding arm and a rod-belt connection structure connecting the elastic transmission structure and the rotating shaft, and a vertical arm is fixedly provided on the support, and the vertical arm cooperates with the elastic transmission structure.

[0012] As a further solution of the present invention: the elastic transmission structure includes a driven shaft rotatably installed on the side of the guiding arm and a driving tube that slidably sleeves with the driven shaft and cooperates with the vertical arm. A convex column is provided on the driving tube, and a groove adapted to the convex column is provided on the outer wall of the driven shaft. The convex column extends into the groove and is slidably connected to the driven shaft, and the groove is arranged in a spiral shape; Wherein, a cross bar is further provided on the side of the guiding arm, the cross bar is slidably connected to a protruding part formed on the outer wall of the driving tube, and a second cylindrical spring with two ends respectively connecting the protruding part and the guiding arm is sleeved on the outer circumference of the cross bar.

[0013] As a further solution of the present invention: the rod-belt connection structure includes a first inclined arm and a second inclined arm whose first ends are rotatably connected by a shaft member. The tail end of the first inclined arm is rotatably connected to the rotating shaft, and the tail end of the second inclined arm is rotatably connected to the driven shaft. The shaft member is also connected to the rotating shaft and the driven shaft through a first transmission belt and a second transmission belt respectively.

[0014] As a further solution of the present invention: two cross arms are provided on the support, and a sliding arm is slidably sleeved on each of the two cross arms. The azimuth adjustment mechanism includes an assembly table arranged between the two sliding arms and a turntable rotatably arranged on the assembly table. A driving motor is installed on the assembly table, and an output shaft of the driving motor is fixedly connected with a driving gear, and the driving gear meshes with a toothed ring arranged on the turntable; Wherein, the sliding arm can be driven by an external horizontal driving member to slide on the cross arm, and a second double-headed electric push rod is further installed at the bottom of the turntable. Two movable ends of the second double-headed electric push rod are respectively provided with a fastener, and the fastener is arranged in an arc shape.

[0015] A method for detecting liquid leakage of an isopropanol container by using the liquid leakage detection device includes the following steps: Step 1, place the container to be inspected upright in the cylinder, and set the container to be inspected in the cylinder by the fastening mechanism; Step 2, the movable plate moves along the length direction of the support, and the telescopic arm group releases and stores elastic potential energy multiple times, so that the liquid in the container impacts the sealing plug multiple times; Step 3: The flipping mechanism is triggered to drive the cylinder to drive the container to be inspected to flip. The container to be inspected is switched from an upright state to an inverted state, and the container is inverted for 5 - 10 minutes. Check whether there is liquid leakage at the sealing plug of the container to complete one detection. Step 4: The movable plate returns to its original position, and the orientation adjustment mechanism works to twist the sealing plug on the container to change the orientation of the sealing plug, and then enter the secondary detection.

[0016] Compared with the prior art, the beneficial effects of the present invention are: During the detection, the movable plate moves towards one side along the length direction of the support. During this process, the guiding mechanism enables the telescopic arm group to release and store elastic potential energy multiple times. When the telescopic arm group releases elastic potential energy, it will cause the cylinder to pop up instantly. Therefore, after the container to be inspected stops rising, the liquid contained inside it will impact the sealing plug due to inertia, thereby taking into account the factor of whether the connection between the sealing plug and the container is stable and ensuring the accuracy of the detection result. Secondly, the entire detection process is carried out multiple times. That is, starting from the secondary detection, before the detection, the orientation adjustment mechanism twists the sealing plug on the container to avoid the position of the sealing plug remaining unchanged during the detection process, so that multiple detections can be carried out for different orientations of the sealing plug, improving the comprehensiveness and detection effect of the detection.

Detailed implementation

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In addition, an element in the present invention is referred to as being "disposed on" or "arranged on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0031] Please refer to Figures 1 - 11 , in the embodiment of the present invention, a liquid leakage detection device for an inverted electronic-grade isopropyl alcohol container includes a support 1, and further includes: A movable plate 2 is movably arranged on the support 1. The movable plate 2 can be driven by a transverse movement driving member arranged on the support 1 to move along the length direction of the support 1, and two sets of oppositely arranged telescopic arm groups are installed on the movable plate 2, and the telescopic arm groups store elastic potential energy; A cylinder 3 is arranged on the movable plate 2 for receiving the container to be inspected, and 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 arm groups and is connected with a flipping mechanism. The flipping mechanism is triggered when the movable plate 2 moves to the latter part of the stroke along the length direction of the support 1, and can drive the cylinder 3 to flip, so that the container in the cylinder 3 is switched from an upright state to an inverted state, and one detection of the container is completed; A guiding mechanism is arranged on the support 1 and cooperates with the two sets of telescopic arm groups. When the movable plate 2 moves towards 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 3 to eject upward, so that the liquid contained in the container to be inspected impacts the sealing plug; An azimuth adjustment mechanism is arranged on the support 1. The azimuth adjustment mechanism can move above the cylinder 3 and perform a screwing action on the sealing plug on the container to be inspected, so as to change the azimuth of the sealing plug in the container to be inspected and enter the secondary detection of the container.

[0032] Among them, it should be supplemented that (please refer to 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 arranged on the cylinder 3, and two clamping members 5 respectively arranged on the two connecting columns 301. The clamping members 5 are arranged in an arc shape, and the movable ends of the first double-headed electric push rod 4 are respectively fixedly connected to the two connecting columns 301. When in use, first, a certain amount of liquid is filled in the container to be inspected (filling it to half a bottle is sufficient), and the container to be inspected is placed in the cylinder 3. Immediately afterwards, 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 drive the two clamping members 5 to move closer to each other along the radial direction of the cylinder 3. Furthermore, 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 detection process; Secondly, the transverse movement driving member (labeled in the figure) includes a lead screw rotatably installed on the support 1 and a guide rod arranged on the support 1. A driving motor is also installed on the support 1. The output end of the driving motor is connected to the lead screw, and the lead screw and the guide rod penetrate through the movable plate 2. The movable plate 2 is threadedly connected to the lead screw and slidably connected to the guide rod. The driving motor is a servo motor with a bidirectional drivable output end. During the detection, the driving motor drives the lead screw to rotate forward or backward, which can make the movable plate 2 move back and forth along the length direction of the support 1 twice, and perform a primary detection and a secondary detection of the container successively.

[0033] Specifically, during operation, after the container to be inspected is placed and fixed, the movable plate 2 moves towards one side along the length direction of the support 1. During this process, the guiding mechanism causes the telescopic arm group to release and store elastic potential energy multiple times. When the telescopic arm group releases elastic potential energy, it will cause the cylinder 3 to pop up instantly. Therefore, after the container to be inspected stops rising, the liquid contained in it will impact the sealing plug due to inertia. After multiple impacts, the movable plate 2 enters the latter part of the stroke. During this process, the flipping mechanism is triggered to drive the cylinder 3 to flip half a circle. Furthermore, the container to be inspected is switched from an upright state to an inverted state, and it is observed whether there is liquid leakage at the sealing plug (it should be noted that during actual detection, it may be difficult to determine whether there is liquid leakage by visual inspection. In this regard, this device can be equipped with a corresponding closed housing. Inside the housing, that is, at the inversion point of the container, a sensor is set, and the high sensitivity of the sensor is used to determine whether there is liquid leakage. The specific measures can be adjusted adaptively according to actual needs, and this application will not elaborate further on this); Subsequently, the movable plate 2 returns to its original position, completing one detection process. If one detection process passes, before the second detection process, the orientation adjustment mechanism operates to rotate the sealing plug on the container to be detected. Subsequently, the second detection is carried out (and so on, and subsequent three - time detections, four - time detections, etc. can be continued). Therefore, the setting of the orientation adjustment mechanism can change the orientation of the sealing plug on the container, and multiple detections are carried out for different orientations of the sealing plug, improving the comprehensiveness and detection effect of the detection.

[0034] Please refer to again Figure 8 , the telescopic arm group includes a guiding arm 6 fixedly installed on the movable plate 2 and a telescopic arm 7 slidably sleeved with the guiding arm 6. One rotating shaft 12 is rotatably installed at each end of the two telescopic arms 7 away from the movable plate 2. The cylinder 3 is arranged between the two rotating shafts 12, and one of the rotating shafts 12 is connected to the flipping mechanism. Two groups of elastic energy storage structures are connected between the guiding arm 6 and the telescopic arm 7.

[0035] Furthermore, the function of the guiding mechanism is to control the sliding of the telescopic arm 7 in the guiding arm 6. When the telescopic arm 7 slides upward in the guiding arm 6, the two telescopic arms 7 can drive the cylinder 3 and the container to be detected in the cylinder 3 to rise. The function of the flipping mechanism is that in the latter part of the movement of the movable plate 2, the flipping mechanism is triggered to drive the rotating shaft 12 to rotate half a circle, so that the rotating shaft 12 drives the cylinder 3 to be inverted, and the container to be detected in the cylinder 3 is switched from the upright state to the inverted state, facilitating the determination of the liquid leakage phenomenon.

[0036] The elastic energy storage structure includes a column 8 arranged on the side of the guiding arm 6 through a protruding block 601 and a first cylindrical spring 9 sleeved on the outer periphery of the column 8. The column 8 penetrates through a lug 10 on the side of the telescopic arm 7, and the lug 10 is slidably connected to the column 8. A through groove 602 for the movement of the lug 10 is provided on the side of the guiding arm 6. The two ends of the first cylindrical spring 9 are respectively connected to the lug 10 and the protruding block 601. The guiding mechanism includes a limiting plate member 23 arranged on the side of the support 1. A connecting arm 21 is arranged between the two telescopic arms 7. A column 22 is fixedly provided on the side of the connecting arm 21 away from the cylinder 3. A groove body matching with the column 22 is provided on the limiting plate member 23. The column 22 extends into the groove body and is slidably connected to the limiting plate member 23. The groove body includes a connected first horizontal groove 2301, a plurality of trapezoidal grooves, a vertical groove 2305, a third horizontal groove 2307, and an inclined groove 2308. The inclined groove 2308 communicates with the middle of the first horizontal groove 2301. A second horizontal groove 2306 is also communicated at the connection between the vertical groove 2305 and the third horizontal groove 2307. The trapezoidal groove includes a connected vertical section 2302, a horizontal section 2303, and an inclined section 2304. A first deflecting member 24 and a second deflecting member 25 are rotatably provided on the limiting plate member 23. The rotation axes of the first deflecting member 24 and the second deflecting member 25 are both connected with torsion springs, and they are respectively located at one end of the vertical groove 2305 facing the third horizontal groove 2307 and one end of the inclined groove 2308 away from the third horizontal groove 2307.

[0037] At first, the column 22 is located at one end of the first horizontal groove 2301 away from the trapezoidal groove, and the first cylindrical 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 deflecting member 25 plays a blocking role), the first cylindrical spring 9 rebounds instantaneously, and the telescopic arm 7 instantaneously lifts up in the guiding arm 6. After the column 22 moves into the horizontal section 2303, the liquid contained in the container to be inspected impacts the sealing plug under the action of inertia. Immediately afterwards, the column 22 gives way through the inclined section 2304, the telescopic arm 7 descends towards the inside of the guiding arm 6, and the first cylindrical spring 9 is compressed again. After passing through a plurality of trapezoidal grooves, the sealing plug on the container to be inspected is impacted by the internal liquid multiple times. Finally, the column 22 enters the vertical groove 2305, and the sealing plug is impacted for the last time. At this time, the column 22 will cause the first deflecting member 24 to deflect towards the third horizontal groove 2307 and then move into the second horizontal groove 2306. During this process, the flipping mechanism is triggered to cause the container to be inspected to be inverted; Preferably, the container to be inspected is kept inverted for 5-10 minutes; Subsequently, the movable plate 2 moves in the opposite direction to reset. During this process, the first deflection member 24 acts as a blocking member. 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, the telescopic arm 7 gradually retracts into the guide arm 6, and the first cylindrical spring 9 is compressed. Finally, the column 22 prompts the second deflection member 25 to deflect toward the first horizontal groove 2301, and the column 22 resets to the initial point (that is, the end of the first horizontal groove 2301 away from the trapezoidal groove).

[0038] 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 very quickly, it still takes a certain amount of time. At this time, in order to ensure the smooth rebound of the first column spring 9 and ensure the effectiveness of the impact treatment of the sealing plug by the liquid in the container to be inspected, the transverse drive member needs to be shut down. However, there are multiple impact processes during the detection process, and the transverse drive member needs to stop and brake multiple times. In this way, when the braking system fails, it is easy to cause damage to the column 22 or other components. For this reason, the vertical section 2302 and the vertical groove 2305 are widened to ensure that the first column spring 9 can rebound smoothly and accurately without stopping the transverse drive member.

[0039] Please refer again Figure 2 , Figure 5 as well as Figure 8 The flip mechanism includes a matching elastic transmission structure provided on the side of the guide arm 6 and a rod-belt connection structure connecting the elastic transmission structure and the rotating shaft 12, and a vertical arm 101 is fixedly provided on the support 1, and the vertical arm 101 matches 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 driving tube 18 that is slidably sleeved with the driven shaft 11 and matched with the vertical arm 101, a boss 1801 is provided on the driving tube 18, and a groove 1101 that matches the boss 1801 is provided on the outer wall of the driven shaft 11, the boss 1801 extends into the groove 1101 and is slidably connected with the driven shaft 11, and the groove 1101 is arranged in a spiral shape. A cross bar 19 is also provided on the side of the guide arm 6, and the cross bar 19 is slidably connected to a protrusion 1802 formed on the outer wall of the driving tube 18, and the outer periphery of the cross bar 19 is sleeved with a second cylindrical spring 20 with two ends respectively connecting the protrusion 1802 and the guide arm 6.

[0040] When the column 22 moves away from the third horizontal groove 2307 in the second horizontal groove 2306, the driving tube 18 is in contact with the vertical arm 101, and the driving tube 18 and the vertical arm 101 remain relatively still. The driven shaft 11 and the driving tube 18 slide relative to each other, and the second cylindrical spring 20 is compressed. The protruding column 1801 slides with the driven shaft 11 through the groove 1101, so that the driven shaft 11 rotates. Then, the driven shaft 11 drives the rotating shaft 12 to rotate half a circle through the rod-belt connection structure, so that the cylinder 3 drives the container to be inspected inside it to be inverted. In the previous stroke of the movable plate 2 returning to reset, the second cylindrical spring 20 gradually rebounds, and the protruding column 1801 again slides with the driven shaft 11 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 restore to an upright state.

[0041] The rod-belt connection structure includes a first inclined arm 14 and a second inclined arm 15 whose head ends are rotatably connected via an axis member 13. The tail end of the first inclined arm 14 is rotatably connected to the rotating shaft 12. The tail end of the second inclined arm 15 is rotatably connected to the driven shaft 11. The axis member 13 is also connected to the rotating shaft 12 and the driven shaft 11 respectively via a first transmission belt 16 and a second transmission belt 17.

[0042] 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 accordingly, the angle between the first inclined arm 14 and the second inclined arm 15 changes. When the driven shaft 11 rotates, the rotating shaft 12 is driven 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.

[0043] Said Figure 1 , Figure 10 as well as Figure 11The support 1 is provided with two cross arms 26, and a sliding arm 27 is slidably sleeved on each of the two cross arms 26. The azimuth adjustment mechanism includes an assembly platform 28 disposed between the two sliding arms 27 and a turntable 29 rotatably disposed on the assembly platform 28. A driving motor 33 is mounted on the assembly platform 28, and a driving gear 34 is fixedly connected to the output shaft of the driving motor 33, and the driving gear 34 is meshed with a gear ring 32 disposed on the turntable 29. The sliding arm 27 can be driven by an external horizontal driving member to slide on the cross arm 26. A second double-headed electric push rod 30 is also mounted at the bottom of the turntable 29, and a fastener 31 is respectively disposed at the two movable ends of the second double-headed electric push rod 30, and the fastener 31 is disposed in an arc shape.

[0044] Whenever the movable plate 2 is reset and the container passes the previous inspection process, the external horizontal driving member (a pneumatic cylinder or a hydraulic cylinder can be selected) drives the sliding arm 27 to slide on the cross arm 26, so that the two fasteners 31 reach the two sides of the container sealing plug, and then the second double-headed electric push rod 30 drives the two fasteners 31 to approach each other to clamp the sealing plug of the container, and then the driving motor 33 drives the driving gear 34 to rotate, and the driving gear 34 can drive the turntable 29 to rotate through the gear ring 32, so that the sealing plug on the container can be screwed to a certain angle, the orientation of the sealing plug on the container can be changed, and multiple inspections are performed on the sealing plug in different orientations, thereby improving the comprehensiveness and inspection effect of the inspection.

[0045] It should be added that, since the shapes of the sealing plugs equipped on different containers to be inspected may be different, the fastener 31 is designed to be replaceable.

[0046] As another embodiment of the present invention, a method for detecting liquid leakage of an isopropyl alcohol container using the liquid leakage detection device is also proposed, comprising the following steps: Step 1: Place the container to be inspected upright in the cylinder 3, and set the container to be inspected in the cylinder 3 by a fastening mechanism; Step 2: The movable plate 2 moves along the length direction of the support 1, and the telescopic arm group releases and stores elastic potential energy multiple times, so that the liquid in the container impacts the sealing plug multiple times; Step 3: The flipping mechanism is triggered to drive the cylinder 3 to flip the container to be inspected, and the container to be inspected is switched from an upright state to an inverted state.
