Description

Technical Field

[0001] This invention relates to the field of microporous membrane detection technology, specifically to an automatic continuous detection device for the porosity of microporous membrane production. Background Technology

[0002] Microporous membranes are thin film materials with tiny pore structures. During use, they can selectively separate, filter, or permeate gases, liquids, or particles based on pore size and surface properties. The porosity of microporous membranes is one of the key indicators for evaluating their performance, directly affecting their separation efficiency and applicable range.

[0003] An existing online thin-film micropore detector, with Chinese patent publication number CN220650542U, includes a worktable. A support mechanism is mounted on the upper surface of the worktable. A negative electrode base plate is mounted on top of the support mechanism, and a positive electrode plate is mounted directly above the negative electrode base plate. An adjustment mechanism is mounted on top of the positive electrode plate, and a detector main unit is fixedly connected to the upper surface of the worktable. This invention, by implementing a positive electrode top plate and a negative electrode base plate above and below the thin film respectively, allows the microporous thin film to pass between the positive and negative electrode base plates. This interaction between the positive and negative electrode base plates detects current changes and triggers an alarm on the detector main unit, thereby achieving the detection of micropores on transparent thin films.

[0004] The aforementioned devices and existing microporous membrane detection devices cannot conveniently and accurately detect the permeability of microporous membranes quickly and accurately. Their complex detection structures and demanding monitoring and adjustment processes easily lead to errors in the test results. While the gas permeation method is more accurate and convenient than the aforementioned devices and existing detection devices, the circular microporous membrane samples placed inside the detection equipment are prone to wrinkling, curling, and overlapping during placement, affecting the uniformity of gas flow and resulting in inaccurate test results. Furthermore, the microporous membrane must be placed inside the device during testing, making it difficult to easily adjust wrinkled or skewed membranes to ensure proper fit with the detection chamber, further complicating the process and leading to inaccurate results. Additionally, when the sampled microporous membrane is not the final product, dust and impurities easily adhere to it, also resulting in inaccurate test results. The low level of automation during sampling and testing hinders continuous and rapid batch testing, impacting production efficiency. Therefore, a device is needed to solve these problems.

[0015] The beneficial effects of this invention are:

[0016] I. The limiting device of the present invention is uniformly provided with limiting adjustment parts. The second motor drives the second drive gear to rotate, which in turn drives the rotating adjustment ring to rotate via the first gear ring, thereby driving the second gear ring to rotate. This makes the rotating adjustment gears in each limiting adjustment part run synchronously. The rotating adjustment column rotates in both directions, causing the adjusting threaded rod to drive the sliding limiting block and the front end parts to move to above the edge of the microporous membrane. The third electric push rod, the second electric push rod, and the first electric push rod run in sequence, causing the pressing roller to contact the microporous membrane first. The second motor controls the sliding limiting block to move back and forth, causing the pressing roller to roll and press along the edge of the microporous membrane, making it unfold and fit against the inner wall of the limiting support frame. Then, the pressing claw moves downward to press the microporous membrane and slides a small distance towards the outside of the limiting support frame, fully and appropriately stretching and unfolding the flat microporous membrane. This avoids wrinkles and overlaps during the addition and placement of the microporous membrane, and avoids interference with the test results caused by uneven membrane. This makes the test results more accurately reflect the true porosity of the microporous membrane.

[0017] II. After the first and second sealing detection units of this invention have established a stable detection environment, data is collected through the gas pressure sensor, flow rate sensor, and vortex flow sensor installed on them. During the detection process, the delivery connection pipe in the first sealing detection unit is connected to an external nitrogen supply device to continuously and stably supply nitrogen at a specified pressure and flow rate into the telescopic detection cylinder. The gas pressure sensor, flow rate sensor, and vortex flow sensor detect the pressure and flow rate of the nitrogen inside the telescopic detection cylinder in real time and transmit the data to the external control system. The system automatically controls the operation of the solenoid valve and, in conjunction with the external nitrogen supply settings, adjusts and controls the flow rate and velocity of the nitrogen entering the telescopic detection cylinder to ensure that the flow rate and velocity of the nitrogen entering for detection are stable and within acceptable limits. Within a specified range, the solenoid valve in the second sealing detection unit is simultaneously adjusted to ensure the stability of the detection environment, thereby improving the accuracy of the detection results. After the first and second sealing detection units are docked with the limiting flat body, they can continuously detect for a specified time to obtain multiple sets of data. The data is transmitted to an externally set data processing device or system, and processed by preset reference comparison values ​​and algorithms such as averaging, removing outliers, and fitting curves to calculate the pore permeability index of the microporous membrane, such as air permeability, porosity, and pore permeability. The analysis and comparison of multiple sets of data can effectively reduce the possible errors in a single detection, more comprehensively and accurately reflect the pore permeability of the microporous membrane, and improve the reliability and accuracy of the detection results.

[0018] Third, this invention, through its specially designed cleaning and feeding section, allows for precise and convenient addition of microporous membranes. During the addition process, the microporous membrane can be cleaned, and after addition, it can be pressed and flattened. This allows for initial flattening and adjustment during addition, combined with secondary adjustments from the setting of pressing rollers and pressing claws, automatically rolling, pressing, and moderately stretching the edges of the microporous membrane to eliminate wrinkles and overlaps, ensuring a flat membrane surface that fits the detection area. Furthermore, this device allows for continuous and convenient addition of microporous membranes for testing, greatly improving testing efficiency. Attached Figure Description

Through the cleaning feeding part 15, it is possible to conveniently add microporous membrane to the limiting flat body 1, and to clean the microporous membrane.

[0042] The first fixed support frame 54 in the first sealing detection unit 16 is U-shaped, and the first fixed support frame 54 in the second sealing detection unit 17 is horizontal. There are six limit adjustment units 29. The front end of the mounting end 43 in three consecutive adjacent limit adjustment units 29 is fixedly installed with a laser range sensor 23, which can detect the distance between the limit adjustment unit 29 and the other three mounting ends 43 to determine the running and position status of the front end of each limit adjustment unit 29. The outer part of the pressing claw 37 is fixedly wrapped with a rubber sleeve to protect the microporous membrane from being pulled. The interior of the limit support frame 24 is evenly provided with placement grooves that are adapted to the front end structure of the fixed connecting rod 45, so as to achieve hidden storage without affecting the normal and smooth addition of the microporous membrane.

[0043] The two sides of the fixed support chassis 19 are fixedly connected to the sliding support plate 6 respectively. The first fixed support frame 54 in the first sealing detection part 16 and the second sealing detection part 17 is fixedly connected to the support leg 8. The second fixed support frame 66 is fixedly connected to the support leg 8 through the support rod. The first docking sealing ring 56 and the second docking sealing ring 68 are adapted to the first docking sealing snap ring 30 and the second docking sealing snap ring 31 to achieve full sealing docking. The rotating snap ring 32 is rotated and snapped into the inside of the limiting support base 21. The second drive gear 20 is meshed with the first toothed ring 25. The bottom ends of the limiting support frame 24 and the limiting support upright plate 28 are fixedly connected to the limiting support base 21.

The sliding limiting snap block 46 is slidably snapped into the inside of the limiting support frame 24 to play the role of sliding and limiting. The fixed connecting rod 45 slides through the limiting support frame 24.

[0044] Working Principle: During use, the device is stably supported and set in the designated position by the support legs 8. The bottom of the support legs 8 has evenly spaced fixing holes to securely fix the device in place. After fixing, the device is connected to an external control system, terminal display, and other devices and equipment for collaborative use. During operation, the circular microporous membrane to be tested is first guided by the tapered guide tube 70 to fall quickly and centrally into the guide limiting tube 67. Since the sliding support blocks 63 evenly spaced at the upper end of the guide limiting tube 67 slide into the upper end of the guide limiting tube 67, the microporous membrane guided by the tapered guide tube 70 will fall onto the sliding support blocks 63. Then, the third motor 59 is started. The fifth electric push rod 61 controls the fixed support plate 60 to descend slowly. The third motor 59 controls the drive rod 73 to rotate slowly in both directions via a reducer, so that the pressing plate 71 and the cleaning sponge block 62 descend a specified distance before the fifth electric push rod 61 stops. At this time, the cleaning sponge block 62 makes slight pressing contact with the upper surface of the microporous membrane located inside the guide limit tube 67. The degree of cleaning pressure can be preset and adjusted in advance as needed. The slowly rotating cleaning sponge block 62 can clean the microporous membrane, removing dust, oil and other impurities to prevent contamination of the test area or blockage of pores. The evenly arranged delivery pipe 72 can connect to the external cleaning fluid supply equipment and drying air guide equipment via a hose. The system is connected to the suction device. Three delivery pipes 72 are provided. The bottom end of one delivery pipe 72 is located on the cleaning sponge block 62, and the bottom ends of two delivery pipes 72 are connected to ventilation holes inside the edge of the pressing plate 71. External cleaning fluid is delivered through the delivery pipes 72 connected to the cleaning sponge block 62, allowing the cleaning sponge block 62 to thoroughly clean the outer surface of the microporous membrane. After cleaning, the cleaning sponge block 62 and the pressing plate 71 rise. The two ventilation holes inside the edge of the pressing plate 71 first draw air into the microporous membrane, and then blow out air for a specified time, allowing the impurities cleaned on the microporous membrane to be extracted and then quickly dried. When double-sided cleaning of the microporous membrane is required, after one side of the microporous membrane is cleaned, the guide and limiting pipes are used to guide the flow through the support rod. The bottom end of tube 67 is inserted into the interior of the conical guide tube 70 to support the microporous membrane, which is then pushed up to the upper end of the conical guide tube 70. This facilitates the removal of the microporous membrane, flipping it over, and placing it back on the sliding support block 63 located inside the upper end of the guide tube 67. This allows for double-sided cleaning of the microporous membrane as needed. This cleaning process can be selected as needed for testing. When the microporous membrane being tested is a deeply processed product and does not require cleaning, the sixth electric push rods 64 cause the sliding support blocks 63 to slide out from the upper end of the guide tube 67 without obstruction. At the start of testing, the first motor 9 is directly started, which drives a synchronous rotating wheel 10 and the first drive gear 12 to rotate.Synchronous rotating wheels 10 on the same side are mounted with synchronous rotating belts 13. Therefore, the synchronous rotating wheels 10 and synchronous rotating belts 13 enable the first drive gears 12 on the same side to rotate synchronously. The two synchronous rotating belts 13 located at the end of the movable adjusting toothed plate 7 are fixedly connected at their midpoints by a synchronous rotating rod 14. Therefore, after starting the first motor 9, the four first drive gears 12 can run synchronously. The symmetrically distributed first drive gears 12 can drive the two movable adjusting toothed plates 7 to move, thereby causing the sliding support plate 6, along with the limiting paving body 1, to slide along the track support plate 5 towards the end of the track support plate 5, sliding to a specified distance. Afterwards, the first motor 9 stops running, and the compression detection plate 2 at the end of the sliding support plate 6 is pressed against the first pressure sensor 3 and the compression detection spring 4 at the end of the track support plate 5. The compression force detected by the first pressure sensor 3 can help determine whether the sliding support plate 6 and the limiting tiling body 1 have moved sufficiently and accurately to the preset position. If the compression force detected by the first pressure sensor 3 is too large or too small and exceeds the preset range, the external alarm will sound, and the operation of the device will automatically stop until the operator intervenes and adjusts it before resuming operation. When the first motor 9 controls the limiting tiling body 1 to slide to the designated position, the limiting tiling body 1 will stop moving. The limiting support frame 24 and the first docking sealing ring 30 in the flat-lay body 1 are moved to directly below the guide limiting tube 67. The seventh electric push rod 69 is activated, which drives the support ring 65 and the guide limiting tube 67 to move downwards by a preset distance. At this time, the guide limiting tube 67 and the first docking sealing ring 30 are precisely docked, and the second docking sealing ring 68 is inserted into the inside of the first docking sealing ring 30 to achieve a sealed alignment. Then, the microporous membrane to be tested is quickly guided by the tapered guide tube 70 and falls into the inside of the guide limiting tube 67, and precisely centered on the guide limiting tube 67 and the first docking sealing ring 30 and falls into the limiting support frame 2. Inside 4, the fifth electric push rod 61 is activated, causing the drive rod 73 and pressing plate 71 to insert into the guide limiting tube 67 and the limiting support frame 24. The microporous membrane that has fallen into the middle of the limiting support frame 24 is repeatedly pressed several times, ensuring that the microporous membrane automatically added to the limiting support frame 24 is fully and evenly laid inside the limiting support frame 24. The fifth electric push rod 61 resets the drive rod 73 and pressing plate 71, and the seventh electric push rod 69 raises and resets the guide limiting tube 67 and the second mating sealing ring 68. At this point, the microporous membrane to be tested is accurately and automatically added to the limiting support frame 24, and the added microporous membrane undergoes its first flattening process.

[0045] When the microporous membrane to be tested is added inside the limiting support frame 24, the second motor 22 starts running. The second motor 22 drives a second drive gear 20 to rotate. The rotating second drive gear 20 drives the rotating adjustment ring 26 to rotate through the first gear ring 25. The rotating adjustment ring 26 drives the second gear ring 27 to rotate. Thus, the rotating second gear ring 27 drives the rotating adjustment gears 49 in each limiting adjustment part 29 to rotate synchronously. The rotating adjustment gears 49 drive the rotating adjustment column 48 to rotate inside the limiting support plate 28. Since the adjusting threaded rod 47 is threaded into the rotating adjustment column 48, and the end of the adjusting threaded rod 47 away from the rotating adjustment column 48 is connected to the sliding limiting card... Block 46 is fixedly connected, and the sliding limit block 46 is slidably engaged inside the limit support frame 24 to achieve limit. Therefore, when the rotating adjusting column 48 rotates forward and backward, the adjusting threaded rod 47 can move back and forth along the inside of the rotating adjusting column 48. Thus, the various components set at the front end of the fixed connecting rod 45 can be controlled by the fixed connecting rod 45 to be discharged outward from the placement groove set inside the limit support frame 24 and moved to the position above the edge of the microporous membrane placed inside the limit support frame 24. Then, the third electric push rod 44 in each limit adjustment part 29 runs, driving the lifting mounting frame 42 to move downward synchronously a specified distance. Then, each second electric push rod 36 runs, and the second electric push rod 36 drives the two ends of the lifting mounting plate 35 to move along the limit. The upright plate 33 moves downwards stably, causing each lifting mounting plate 35 to move to a preset position. Then, the first electric push rod 34 above the pressing roller 38 operates, controlling the pressing roller 38 to move downwards and contact the microporous membrane. At this time, the second motor 22 controls the second drive gear 20 to rotate forward and backward, ultimately indirectly controlling each sliding limit block 46 to move back and forth along the limit support frame 24. This causes each pressing roller 38 to roll and press along the edge of the microporous membrane, ensuring that the microporous membrane fully unfolds and adheres to the inner wall of the middle part of the limit support frame 24. After repeated pressing for a specified time, the front end of the fixed connecting rod 45 moves to the edge of the microporous membrane, and then... The first electric push rod 34 causes each pressing claw 37 to move downwards and press onto the microporous membrane. At this time, the second motor 22 again controls each sliding limit block 46 and fixed connecting rod 45 to slide a small distance towards the outside of the limiting support frame 24. This allows the evenly distributed pressing claws 37 to fully and appropriately stretch and unfold the flattened microporous membrane, preventing wrinkles and overlaps on the microporous membrane, making subsequent testing more accurate. After the synchronous stretching allows the microporous membrane to be fully flattened and unfolded, the pressing claws 37 and pressing rollers 38 press the edges of the microporous membrane again to ensure that the fully stretched and unfolded edges of the microporous membrane are fully pressed and limited to fit the inside of the limiting support frame 24. After the flattening and limiting adjustment, the first motor 9 runs again.The first motor 9 resets the sliding support plate 6 and the moving adjusting toothed plate 7, thereby driving the limiting tiling body 1 to reset to the detection position. At this time, the compression detection plate 2 at the end of the sliding support plate 6, the first pressure sensor 3 and the compression detection spring 4 at the end of the compression track support plate 5, and the compression detection plate 2 at the end of the sliding support plate 6 detect the position of the limiting tiling body 1, ensuring the accurate position of the limiting tiling body 1 after the lateral movement stops. When the limiting tiling body 1 moves to the detection position, the fourth electric push rod 53 in the first sealing detection unit 16 and the second sealing detection unit 17 operates. The fourth electric push rod 53 can drive the telescopic detection cylinder 52 to slide in the middle of the first fixed support frame 54, so that the first mating sealing ring 56 in the first sealing detection unit 16 is inserted. The first mating sealing ring 56 in the second sealing detection unit 17 is inserted into the second mating sealing ring 31, so that the first mating sealing insert ring 56 in the second sealing detection unit 17 is inserted into the second mating sealing ring 31. The delivery connecting pipe 50 in the first sealing detection unit 16 is connected to an external nitrogen delivery supply device through a hose. Nitrogen gas at a specified pressure and flow rate is continuously and stably delivered into the telescopic detection cylinder 52 through the delivery connecting pipe 50. At this time, the gas pressure sensor 55, flow rate sensor 57, and vortex flow sensor 58 installed on the telescopic detection cylinder 52 in the first sealing detection unit 16 can detect the pressure and flow rate of the nitrogen gas inside the telescopic detection cylinder 52, and transmit the detected values ​​to the internal control system, which automatically controls the operation of the solenoid valve 51, combined with the external... The nitrogen supply system is equipped with auxiliary adjustment and control to regulate the flow rate of nitrogen entering the telescopic detection cylinder 52, ensuring that the flow rate of nitrogen entering the first sealing detection unit 16 for detection is stable and within a specified range. Furthermore, when the solenoid valve 51 in the first sealing detection unit 16 opens and closes, the solenoid valve 51 in the second sealing detection unit 17 adjusts synchronously to ensure the accuracy of the detection results. The nitrogen flow is intercepted by a microporous membrane at the center of the limiting support frame 24 before entering the telescopic detection cylinder 52 in the second sealing detection unit 17. The flow rate is then detected by the gas pressure sensor 55, flow rate sensor 57, and vortex flow sensor 58 within the second sealing detection unit 17. Pressure and flow rate are measured by the gas pressure sensor 55, flow rate sensor 57, and vortex flow sensor 58 in the first and second sealing detection units 16 and 17, respectively. The measured values ​​are then transmitted to an external data processing device or system. Combined with preset algorithms such as averaging, outlier removal, and curve fitting, the pore permeability indicators of the microporous membrane, such as air permeability, porosity, and pore flow rate, are calculated. After docking with the limiting and flattening body 1, the first and second sealing detection units 16 and 17 can continuously detect for a specified time, obtaining multiple sets of data for thorough analysis. After detection, the first and second sealing detection units 16 and 17 separate from the limiting and flattening body 1, and the detected microporous membrane is removed from inside the limiting support frame 24.The limiting and flattening body 1 is moved to below the cleaning and feeding section 15 by repeating the above steps, and the microporous membrane to be tested is added again. This allows the device to easily and quickly achieve continuous testing, making the testing more convenient and the results more accurate.
