Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and specifically to a testing device for testing battery separators. Background Technology

[0002] In lithium-ion batteries, the separator plays a crucial role. As a key component between the positive and negative electrodes, it must not only have good ion conductivity to allow lithium ions to smoothly shuttle between the two electrodes during charging and discharging, but also have excellent electronic insulation to prevent direct contact between the positive and negative electrodes from causing a short circuit, thereby ensuring the safe and stable operation of the battery and its full performance.

[0003] Lithium-ion batteries are widely used in electric vehicles, energy storage systems, portable electronic devices and many other fields. This has brought unprecedented attention to the quality and performance of battery separators. In order to ensure that battery separators can meet the stringent requirements for use, it is particularly important to accurately test their various performance indicators.

[0004] Currently, there are various testing technologies for battery separators, including optical testing, electron microscopy analysis, and mechanical performance testing. These testing methods can evaluate various properties of the separator to a certain extent, but in practical applications, there is a common and thorny problem—separator wrinkles.

[0005] In traditional testing procedures, whether placing the diaphragm on the testing platform or performing sampling and transfer operations, the diaphragm itself is thin, soft, and has a certain degree of elasticity, making it prone to wrinkles. Once wrinkles appear, the refraction and scattering of light during optical testing will be severely affected, causing the originally clear image to become blurry. Some tiny holes and defects may be obscured by wrinkles, making it impossible for inspectors to accurately judge the actual quality of the diaphragm, resulting in incomplete testing.

[0006] For electron microscopy analysis, the presence of wrinkles will change the height difference on the diaphragm surface, affecting the focusing and imaging effect of electrons, thus interfering with the accurate observation of the diaphragm's microstructure. In mechanical performance testing, wrinkles will also prevent the applied force from being evenly distributed on the diaphragm, leading to deviations in test results and failing to truly reflect the mechanical properties of the diaphragm.

[0007] Therefore, this invention provides a testing device for testing battery separators to solve the above-mentioned problems. Utility Model Content

[0008] In view of the above situation and to overcome the defects of the prior art, this utility model provides a detection device for detecting battery separators, so as to solve the problem of avoiding separator wrinkles and preventing incomplete detection due to wrinkles.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A testing device for testing battery separators includes a base. A connecting plate and a fixing plate are fixedly mounted on the front and rear ends of the base, respectively. A winding roller is mounted on the front of the connecting plate, and a testing component is mounted on the front end of the connecting plate. A sliding frame is provided on the outer wall of the fixing plate, and a connecting column is fixedly mounted on the rear end of the connecting plate. A cleaning frame is mounted on the outer wall of the connecting column, and a cleaning plate is provided on the outer wall of the cleaning frame. The cleaning plate is driven by a drive wheel mounted on the cleaning frame and driven by the separator. This device, through the arrangement of the cleaning plate and the drive wheel, enables the cleaning plate to automatically move during testing, cleaning the outer wall of the separator by the transport of the separator. This linkage function prevents lateral wrinkles in the separator. Simultaneously, the pressure from the drive wheel stretches the separator, achieving tension and eliminating vertical wrinkles. This ensures that the separator is taut during testing and avoids wrinkles, thus guaranteeing the accuracy of the test data.

[0011] Preferably, the take-up roller is rotatably connected to the outer wall of the take-up frame, and the take-up frame is fixedly installed at one end of the top of the base. There are two take-up frames, which are driven together by a take-up shaft. The take-up roller is driven together by the take-up shaft and the output end of the drive motor. When in use, the drive motor is started, which drives the take-up roller to rotate. At the same time, under the action of the take-up shaft, the two take-up rollers are driven to rotate synchronously to achieve the take-up function. In addition, when taking up the diaphragm, the device can stretch synchronously without the need for control by other power sources.

[0012] Preferably, there are two sliding frames, which are arranged in parallel. A feeding roller is rotatably connected to the outer wall of each sliding frame, and the feeding roller is detachably connected.

[0013] Preferably, a groove is formed on the outer wall of the fixed plate, and a reciprocating screw is rotatably connected inside the groove. A threaded plate is threadedly connected to the outer wall of the reciprocating screw, and the sliding frame is fixedly installed on the outer wall of the threaded plate. A first reciprocating bevel gear is fixedly installed on the outer wall of one end of the reciprocating screw, and the first reciprocating bevel gear meshes with a second reciprocating bevel gear. The second reciprocating bevel gear is fixedly installed on the outer wall of one end of the drive shaft. The drive shaft is rotatably connected to the side walls of the fixed plate and the connecting plate. A first driving bevel gear is fixedly installed on the outer wall of the other end of the drive shaft, and the first driving bevel gear meshes with a second driving bevel gear. The second driving bevel gear is fixedly installed on the outer wall of the take-up shaft. When the drive motor is started and rotated, the two driving bevel gears... The drive shaft will rotate synchronously. At this time, the drive shaft, through the action of two reciprocating bevel gears, synchronously drives the reciprocating screw to rotate, causing the threaded plate on the outer wall of the reciprocating screw to move left and right. This allows the threaded plate to drive the sliding frame to move left and right. When the feed roller is large, and the diaphragm wound on its outer wall is threaded and cross-wound, the feed roller of this device can move left and right, ensuring that the outlet end of the diaphragm on the outer wall of the feed roller is always opposite to the inlet end of the cleaning frame. This avoids the phenomenon of crossing or spiral winding between the two, and prevents the diaphragm from wrinkling. This device can automatically align the left and right displacement of the feed roller with the inlet end of the cleaning frame. This device can achieve different driving speeds by changing the reciprocating screw or bevel gears to meet the displacement of feed rollers of different sizes, avoiding excessive or insufficient displacement of the feed roller.

[0014] Preferably, a fixing frame is fixedly installed on the top of the connecting column, a bidirectional lead screw is rotatably connected to the outer wall of the fixing frame, a first rotating bevel tooth is fixedly installed on the outer wall of the bidirectional lead screw, the first rotating bevel tooth is meshed with a second rotating bevel tooth, the second rotating bevel tooth is installed on the outer wall of the rotating shaft, the rotating shaft is rotatably connected to the side wall of the fixing frame, and the first connecting bevel tooth is installed on the outer wall of the middle part of the rotating shaft.

[0015] Preferably, a cleaning frame is fixedly installed on the side wall of the connecting column. A cleaning hole is formed on the outer wall of the cleaning frame, and an inner groove is formed on the inner wall of the cleaning frame. An adjusting plate is slidably connected inside the inner groove. An adjusting block is fixedly installed on the top of the adjusting plate. The adjusting block is threadedly connected to the outer wall of the adjusting screw, and the adjusting screw is rotatably connected to the inner top wall of the cleaning frame. In use, the rotating shaft drives the bidirectional screw to rotate under the action of the rotating bevel gear. Simultaneously, when the diaphragm passes through the cleaning hole, the device can perform a second scraping function on the diaphragm, achieving multiple scraping effects. Furthermore, the height of the adjusting plate can be adjusted by rotating the adjusting screw to facilitate scraping and cleaning of diaphragms of different thicknesses. The adjusting block of the device can increase the adjustment distance of the adjusting plate, facilitating the adjustment of different heights.

[0016] Preferably, a sliding plate is threaded onto the outer wall of the bidirectional lead screw, and a cleaning plate is slidably connected inside the sliding plate. A compression spring is fixedly installed on the inner wall of the sliding plate, and the other end of the compression spring is fixedly connected to one end of the cleaning plate. A wrinkle-removing block is fixedly installed on the other end of the cleaning plate. There are multiple wrinkle-removing blocks, arranged in pairs (left and right) facing each other, with two groups of wrinkle-removing blocks arranged vertically opposite each other. The two groups of wrinkle-removing blocks are connected by a drive belt. In the initial state, the wrinkle-removing blocks and the cleaning plate extend under the action of the compression spring, and the wrinkle-removing blocks abut against the outer wall of the diaphragm. When the rotating shaft is driven by two rotating bevel gears, it rotates the bidirectional lead screw. Two sliding plates are mounted on the outer wall of the bidirectional lead screw with opposite threads. When the bidirectional lead screw rotates, the two sliding plates first move in opposite directions, and then move relative to each other, causing the wrinkle-removing blocks to scrape left and right. When the device starts winding the diaphragm, it will synchronously drive the wrinkle-removing blocks to move, thereby scraping the packaging tape laterally and preventing wrinkles from appearing on the outer wall of the diaphragm. This prevents incomplete packaging or gaps caused by wrinkles inherent in the diaphragm itself or wrinkles generated during stretching. The device has multiple wrinkle-removing blocks to ensure wrinkle removal efficiency. The cleaning plate of the device can always push outwards and keep in contact with the outer wall of the diaphragm, achieving adaptive adjustment and scraping.

[0017] Preferably, an mounting shaft is installed at the center of the drive wheel, one end of the mounting shaft is rotatably connected to the outer wall of the telescopic plate, and the fixed end of the telescopic plate is installed at the bottom of the fixed frame.

[0018] Preferably, a first mounting bevel tooth is fixedly installed on the outer wall of the other end of the mounting shaft. The first mounting bevel tooth meshes with a second mounting bevel tooth. The second mounting bevel tooth is installed on the outer wall of the telescopic shaft. The telescopic shaft is slidably connected to the outer wall of the linkage shaft via a limiting strip. A compression spring is installed on the inner wall of the linkage shaft, and the other end of the compression spring is fixedly connected to the top of the telescopic shaft. A second connecting bevel tooth is installed on the outer wall of the top of the linkage shaft, and the second connecting bevel tooth meshes with the first connecting bevel tooth. In the initial state, the drive wheel of this device is activated by the compression spring. Under the action of the spring, it extends outward, so that the drive wheel can always be tightly pressed against the outer wall of the diaphragm. At the same time, the drive wheel presses against the diaphragm, achieving tension again and satisfying the multiple tensioning function. This enables multiple steps to remove vertical wrinkles and avoid the formation of wrinkles. When the drive wheel rotates, the two bevel gears drive the linkage shaft to rotate. The rotating shaft drives the wrinkle removal block to move, achieving the linkage function. This allows the removal of vertical wrinkles and the removal of horizontal wrinkles to be achieved simultaneously, forming a linkage function and achieving multiple wrinkle removal functions.

[0019] Preferably, the detection component includes a detection frame and a detection box. The detection frame is fixedly installed on the outer wall of the upper part of the connecting plate. A control board is installed on the top of the detection frame, and a detection box is installed on the lower part of the detection frame. The detection box is electrically connected to the control board. A sliding box is slidably connected inside the detection box. A detection spring is fixedly installed at one end of the sliding box, and the other end of the detection spring is fixedly connected to the inner wall of the detection box. A detection brush is fixedly installed on one side of the other end of the sliding box, and a detection head is fixedly installed on the other side of the other end of the sliding box. After wrinkle removal, the device uses the detection brush to detect the flatness of the outer wall of the diaphragm. When irregularities or depressions occur, the detection brush can detect them and stop the device from operating. The detection head of the device detects the diaphragm, achieving a dual detection effect. At the same time, the detection spring of the device can abut against the detection brush, ensuring that the detection brush is always in contact with the outer wall of the diaphragm. This device is suitable for detecting diaphragms of various thicknesses.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This device, through the arrangement of the cleaning plate and drive wheel, enables automatic movement of the cleaning plate during testing, driven by the diaphragm's transmission. This cleans the outer wall of the diaphragm, achieving a linked function and preventing lateral wrinkles in the diaphragm. Simultaneously, the driving wheel's pressure stretches the diaphragm, eliminating vertical wrinkles and ensuring the diaphragm remains taut and wrinkle-free during testing. This guarantees the accuracy of the test data.

[0022] 2. When the feed roller is large, and the diaphragm wound on its outer wall is spirally wound, the feed roller can move left and right, so that the outlet end of the diaphragm on the outer wall of the feed roller is always opposite to the inlet end of the cleaning frame. This can avoid the phenomenon of crossing and spiral winding between the two, and avoid the phenomenon of wrinkling of the diaphragm. The device can automatically align the feed roller with the inlet end of the cleaning frame by moving left and right.

[0023] 3. When in use, the rotation of the rotating shaft drives the bidirectional lead screw to rotate under the action of the rotating bevel gear. At the same time, when the diaphragm passes through the cleaning hole, the device can scrape the diaphragm again, achieving multiple scraping effects. The height of the adjusting plate can be adjusted by rotating the adjusting screw, so as to scrape and clean diaphragms of different thicknesses. In addition, the adjusting block of the device can increase the adjustment distance of the adjusting plate, making it easy to adjust different heights.

[0024] 4. When the device starts winding the diaphragm, it will simultaneously move the wrinkle-removing blocks to achieve lateral scraping of the packaging tape, avoiding wrinkles on the outer wall of the diaphragm. This prevents incomplete packaging or gaps caused by wrinkles inherent in the diaphragm itself or wrinkles generated during stretching. The device has multiple wrinkle-removing blocks to ensure wrinkle removal efficiency. The cleaning plate of the device can always push outwards and maintain contact with the outer wall of the diaphragm, achieving adaptive adjustment and scraping.

[0025] 5. In its initial state, the drive wheel of this device extends outward under the action of the compression spring, ensuring that the drive wheel remains tightly pressed against the outer wall of the diaphragm. Simultaneously, the drive wheel presses against the diaphragm, achieving further tensioning and fulfilling multiple tensioning functions. This allows for multiple steps of vertical wrinkle removal, preventing wrinkle formation. Furthermore, as the drive wheel rotates, the two bevel gears drive the linkage shaft, which in turn drives the wrinkle-removing block, achieving a linkage function. This ensures that the removal of vertical and horizontal wrinkles is simultaneous, forming a linked function and achieving multiple wrinkle removal capabilities.

[0026] 6. After wrinkle removal, this device uses a detection brush to check the flatness of the outer wall of the diaphragm. When irregularities or depressions are found, the detection brush can detect them and stop the device from running. The detection head of this device detects the diaphragm, achieving a dual detection effect. At the same time, the detection spring of this device can push against the detection brush, ensuring that the detection brush is always in contact with the outer side of the diaphragm. It is suitable for detecting diaphragms of various thicknesses. Attached Figure Description

[0047] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0048] A testing device for testing battery separators, as shown in the attached document. Figure 1-2 As shown, the device includes a base 1, with a connecting plate 2 and a fixing plate 3 fixedly installed at its front and rear ends, respectively. A winding roller 10 is installed at the front of the connecting plate 2, and a detection component 4 is installed at the front end of the connecting plate 2. A sliding frame 5 is provided on the outer wall of the fixing plate 3, and a connecting column 6 is fixedly installed at the rear end of the connecting plate 2. A cleaning frame 7 is installed on the outer wall of the connecting column 6, and a cleaning plate 8 is provided on the outer wall of the cleaning frame 7. The cleaning plate 8 is driven by a drive wheel 9, which is mounted on the cleaning frame 7 and driven by a diaphragm. Through the arrangement of the cleaning plate 8 and the drive wheel 9, this device can automatically drive the cleaning plate 8 to move during detection, cleaning the outer wall of the diaphragm by the transmission of the diaphragm, achieving a linkage function and preventing transverse wrinkles in the diaphragm. Simultaneously, the pressure of the drive wheel 9 stretches the diaphragm, achieving tension and eliminating vertical wrinkles. This ensures that the diaphragm is taut during detection and avoids wrinkles, guaranteeing the accuracy of the detection data.

[0049] As attached Figure 1As shown, the take-up roller 10 is rotatably connected to the outer wall of the take-up frame 11. The take-up frame 11 is fixedly installed at one end of the top of the base 1. There are two take-up frames 11, which are driven and connected by a take-up shaft 13. The take-up roller 10 is driven and connected to the output end of the drive motor 12 through the take-up shaft 13. When the device is in use, the drive motor 12 is started, which drives the take-up roller 10 to rotate. At the same time, under the action of the take-up shaft 13, the two take-up rollers 10 are driven to rotate synchronously to realize the take-up function. At the same time, the device can stretch synchronously when taking up the diaphragm without the need for control of other power sources.

[0050] As attached Figure 1-2 As shown, there are two sliding frames 5, which are arranged in parallel. A feeding roller 501 is rotatably connected to the outer wall of the sliding frame 5. The feeding roller 501 is detachably connected.

[0051] As attached Figure 1-3 As shown, a groove 301 is provided on the outer wall of the fixed plate 3. A reciprocating screw 302 is rotatably connected inside the groove 301. A threaded plate 303 is threadedly connected to the outer wall of the reciprocating screw 302. The sliding frame 5 is fixedly installed on the outer wall of the threaded plate 303. A first reciprocating bevel gear 304 is fixedly installed on the outer wall of one end of the reciprocating screw 302. The first reciprocating bevel gear 304 meshes with a second reciprocating bevel gear 306. The second reciprocating bevel gear 306 is fixedly installed on the outer wall of one end of the drive shaft 305. The drive shaft 305 is rotatably connected to the side walls of the fixed plate 3 and the connecting plate 2. A first drive bevel gear 307 is fixedly installed on the outer wall of the other end of the drive shaft 305. The first drive bevel gear 307 meshes with a second drive bevel gear 308. The second drive bevel gear 308 is fixedly installed on the outer wall of the take-up shaft 13. When the drive motor 12 is started and rotated, the two drive bevel gears will drive the shaft synchronously. The drive shaft 305 rotates, and under the action of two reciprocating bevel gears, the drive shaft 305 synchronously drives the reciprocating screw 302 to rotate, causing the threaded plate 303 on the outer wall of the reciprocating screw 302 to move left and right. This allows the threaded plate 303 to drive the sliding frame 5 to move left and right. When the feed roller 501 is large, the diaphragm wound on its outer wall is threaded and cross-wound, which enables the feed roller 501 of this device to move left and right. This ensures that the outlet end of the diaphragm on the outer wall of the feed roller 501 is always opposite to the inlet end of the cleaning frame 7, avoiding the phenomenon of crossing and spiral winding, and preventing the diaphragm from wrinkling. This device can automatically align the left and right displacement of the feed roller 501 with the inlet end of the cleaning frame 7. This device can achieve different driving speeds by replacing the reciprocating screw 302 or the bevel gears to meet the displacement of different sized feed rollers 501, thus avoiding the feed roller 501 displacement being too large or too small.

[0052] As attached Figure 4-5As shown, a fixing bracket 702 is fixedly installed on the top of the connecting column 6. A bidirectional lead screw 703 is rotatably connected to the outer wall of the fixing bracket 702. A first rotating bevel gear 704 is fixedly installed on the outer wall of the bidirectional lead screw 703. The first rotating bevel gear 704 is meshed with a second rotating bevel gear 705. The second rotating bevel gear 705 is installed on the outer wall of the rotating shaft 706. The rotating shaft 706 is rotatably connected to the side wall of the fixing bracket 702. A first connecting bevel gear 707 is installed on the outer wall of the middle part of the rotating shaft 706.

[0053] As attached Figure 4-5 As shown, a cleaning frame 7 is fixedly installed on the side wall of the connecting column 6. A cleaning hole 701 is opened on the outer wall of the cleaning frame 7, and an inner groove 708 is opened on the inner wall of the cleaning frame 7. An adjusting plate 709 is slidably connected inside the inner groove 708. An adjusting block 710 is fixedly installed on the top of the adjusting plate 709. The adjusting block 710 is threadedly connected to the outer wall of the adjusting screw 711. The adjusting screw 711 is rotatably connected to the inner top wall of the cleaning frame 7. When this device is in use, the rotation of the rotating shaft 706 can drive the bidirectional screw 703 to rotate under the action of the rotating bevel gear. At the same time, when the diaphragm passes through the cleaning hole 701, this device can perform a second scraping function on the diaphragm, realizing a multiple scraping effect. At the same time, the height of the adjusting plate 709 can be adjusted by rotating the adjusting screw 711, so as to scrape and clean diaphragms of different thicknesses. In addition, the adjusting block 710 of this device can increase the adjustment distance of the adjusting plate 709, making it easy to adjust different heights.

[0054] As attached Figure 6-7As shown, a sliding plate 712 is threaded onto the outer wall of the bidirectional lead screw 703. A cleaning plate 8 is slidably connected inside the sliding plate 712. A compression spring 715 is fixedly installed on the inner wall of the sliding plate 712. The other end of the compression spring 715 is fixedly connected to one end of the cleaning plate 8. A wrinkle-removing block 714 is fixedly installed on the other end of the cleaning plate 8. There are multiple wrinkle-removing blocks 714, arranged in pairs (left and right) to form a group, with two groups arranged vertically opposite each other. The two groups of wrinkle-removing blocks 714 are connected by a drive belt 716. In the initial state, the wrinkle-removing blocks 714 and the cleaning plate 8 extend under the action of the compression spring 715, and the wrinkle-removing blocks 714 abut against the outer wall of the diaphragm. When the rotating shaft 706 is driven by the two rotating bevel gears, it drives the bidirectional lead screw 703 to rotate. The two sliding plates 712 of this device are mounted on the outer wall of the bidirectional lead screw 703 with opposite threads. When the bidirectional lead screw 703 rotates, the two sliding plates 712 first move in opposite directions, and then move relative to each other, so that the wrinkle removal block 714 scrapes left and right. When the device starts to wind up the diaphragm, it will synchronously drive the wrinkle removal block 714 to move, so as to achieve lateral scraping of the packaging tape, avoid wrinkles on the outer wall of the diaphragm, and prevent incomplete packaging or gaps caused by wrinkles on the diaphragm itself or wrinkles caused by stretching. The device has multiple wrinkle removal blocks 714 to ensure wrinkle removal efficiency. The cleaning plate 8 of this device can always push outward and keep in contact with the outer wall of the diaphragm to achieve adaptive adjustment and scraping.

[0055] As attached Figure 8 As shown, a mounting shaft 901 is installed at the center of the drive wheel 9. One end of the mounting shaft 901 is rotatably connected to the outer wall of the telescopic plate 902. The fixed end of the telescopic plate 902 is installed at the bottom of the fixed frame 702.

[0056] As attached Figure 9-10As shown, a first mounting bevel gear 903 is fixedly mounted on the outer wall of the other end of the mounting shaft 901. The first mounting bevel gear 903 is engaged with a second mounting bevel gear 904. The second mounting bevel gear 904 is mounted on the outer wall of the telescopic shaft 905. The telescopic shaft 905 is slidably connected to the outer wall of the linkage shaft 907 via a limiting strip 906. A compression spring 908 is mounted on the inner wall of the linkage shaft 907. The other end of the compression spring 908 is fixedly connected to the top of the telescopic shaft 905. A second connecting bevel gear 909 is mounted on the outer wall of the top of the linkage shaft 907. The second connecting bevel gear 909 is engaged with the first connecting bevel gear 907. The drive wheel 9 of this device initially... In this state, under the action of the compression spring 908, the drive wheel 9 extends outward, ensuring that it remains tightly pressed against the outer wall of the diaphragm. Simultaneously, the drive wheel 9 presses against the diaphragm, achieving further tensioning and fulfilling multiple tensioning functions. This allows for multiple steps of vertical wrinkle removal, preventing wrinkle formation. Furthermore, as the drive wheel 9 rotates, the two bevel gears drive the linkage shaft 907 to rotate. The rotating shaft 706 then drives the wrinkle-removing block 714, achieving a linkage function. This ensures that the removal of vertical and horizontal wrinkles is simultaneous, forming a linkage function and achieving multiple wrinkle removal capabilities.

[0057] As attached Figure 11 As shown, the detection component 4 includes a detection frame 401 and a detection box 403. The detection frame 401 is fixedly installed on the outer wall of the upper part of the connecting plate 2. A control plate 402 is installed on the top of the detection frame 401, and a detection box 403 is installed on the lower part of the detection frame 401. The detection box 403 is electrically connected to the control plate 402. A sliding box 404 is slidably connected inside the detection box 403. A detection spring 405 is fixedly installed at one end of the sliding box 404, and the other end of the detection spring 405 is fixedly connected to the inner wall of the detection box 403. A detection spring 405 is fixedly installed on one side of the other end of the sliding box 404. Equipped with a detection brush 406, a detection head 407 is fixedly installed on the other side of the sliding box 404. After wrinkle removal, the device uses the detection brush 406 to check the flatness of the outer wall of the diaphragm. When irregularities or depressions occur, the detection brush 406 can detect them and stop the device from operating. The detection head 407 of this device checks the diaphragm, achieving a dual detection effect. At the same time, the detection spring 405 of this device can abut against the detection brush 406, ensuring that the detection brush 406 is always in contact with the outer side of the diaphragm. It is suitable for checking diaphragms of various thicknesses.
