Description

Technical Field

[0001] This utility model relates to the field of diaphragm testing technology, and in particular to a device for puncturing a diaphragm. Background Technology

[0002] The separator is a thin film used in lithium-ion batteries to separate the positive and negative electrodes during the electrolytic reaction, preventing direct reaction and energy loss in the electrolyte. In the structure of a lithium battery, the separator is one of the key internal components. The performance of the separator determines the battery's interface structure, internal resistance, and other characteristics, directly affecting the battery's capacity, cycle life, and safety performance. A high-performance separator plays a crucial role in improving the overall performance of the battery. Therefore, it is necessary to conduct mechanical property tests on the separator.

[0003] The puncture area test is a crucial component in the mechanical performance testing of diaphragms. The current procedure involves heating a soldering iron to the required temperature (e.g., around 400°C), then manually holding the iron and vertically piercing the diaphragm. This is repeated multiple times to create several through-holes (e.g., 6-10 holes). Three suitable circular holes are then identified from these through-holes, and their areas are calculated to determine the puncture area. However, manually moving the soldering iron can lead to tilting, making it impossible to guarantee a vertical movement. This necessitates creating more than three through-holes on the diaphragm, resulting in low testing efficiency.

[0004] Therefore, there is an urgent need for a highly efficient membrane rupture device. Utility Model Content

[0005] The purpose of this invention is to provide a membrane rupture device to solve the technical problem of low efficiency in the prior art.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] The membrane rupture device includes:

[0008] Base assembly;

[0009] A fixing component is disposed on the base assembly, and the fixing component fixes the membrane to be broken;

[0010] A driving mechanism includes a connector and a driving assembly. The connector is slidably connected to the base assembly along a first direction, and the driving assembly is connected to the connector to drive the connector to move in the first direction.

[0011] A piercing element, which is connected to the connector and is disposed opposite to the fixing component in the first direction.

[0012] The beneficial effects of the above technical solution are as follows:

[0013] The membrane to be punctured is fixed by a fixing component to reduce deformation during puncture and ensure the regularity of the puncture hole shape. A driving mechanism is set up, which includes a connector and a driving component. The connector is slidably connected to the base component along a first direction. The puncturing component is connected to the connector. The driving component drives the connector to move in the first direction, thereby driving the puncturing component to move in the first direction. This allows the membrane to be punctured in a direction perpendicular to the membrane to be punctured, ensuring the accuracy of the movement of the puncturing component along the first direction, reducing the risk of irregular puncture holes, and ensuring that all puncture holes obtained meet the test requirements. This reduces the number of puncture holes required and improves test efficiency. Attached Figure Description

Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0030] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or it can be located in between the component.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] This embodiment provides a perforated membrane device for testing the perforated membrane area of ​​a membrane to be perforated, which has high testing efficiency.

[0033] It should be noted that the membrane to be broken can be the separator in a lithium-ion battery, or it can be a membrane in other products. This embodiment does not limit this.

[0034] For example, such as Figures 1 to 7 As shown, the membrane puncture device includes a base assembly 1, a fixing assembly 2, a driving mechanism 3, and a puncture component 4. The base assembly 1 supports the fixing assembly 2, the driving mechanism 3, and the puncture component 4.

[0035] like Figure 1As shown, the fixing component 2 is disposed on the base component 1 and is used to fix the membrane to be broken. In this embodiment, the fixing component 2 is detachably disposed on the base component 1, that is, the position of the fixing component 2 relative to the base component 1 is variable, so as to fix the membrane to be broken on the fixing component 2.

[0036] The driving mechanism 3 in this embodiment includes a connector 31 and a driving assembly 32. The connector 31 is slidably connected to the base assembly 1 along the first direction Z, so that the base assembly 1 restricts the movement direction of the connector 31, ensuring that the movement direction of the connector 31 relative to the base assembly 1 is the first direction Z. The driving assembly 32 is connected to the connector 31 to drive the connector 31 to move in the first direction Z. The piercing element 4 is connected to the connector 31, so that when the connector 31 moves in the first direction Z, it can drive the piercing element 4 to move in the first direction Z. Furthermore, the piercing element 4 is disposed opposite to the fixing assembly 2 in the first direction Z, so as to pierce the membrane to be pierced fixed on the fixing assembly 2.

[0037] In some optional embodiments, the first direction Z is the same as the thickness direction of the membrane to be punctured, which is fixed to the fixing component 2, so as to puncture the membrane vertically. For example, when the membrane to be punctured is placed horizontally, the first direction Z can be a vertical direction. Of course, it is understood that the first direction Z can also be other directions in space, and this embodiment does not limit it.

[0038] When using the puncture membrane device provided in this embodiment, the membrane to be punctured is first fixed on the fixing component 2, and then the driving component 32 drives the connecting member 31 to move in the first direction Z toward the direction closer to the fixing component 2, thereby driving the puncturing member 4 to move in the first direction Z toward the direction closer to the fixing component 2, so as to puncture the membrane to be punctured fixed on the fixing component 2.

[0039] The puncture membrane device provided in this embodiment uses a fixing component 2 to fix the membrane to be punctured, thereby reducing deformation of the membrane during the puncture process and ensuring the regularity of the puncture hole shape. A driving mechanism 3 is provided, which includes a connecting member 31 and a driving component 32. The connecting member 31 is slidably connected to the base component 1 along the first direction Z. The puncturing member 4 is connected to the connecting member 31. The driving component 32 drives the connecting member 31 to move along the first direction Z, thereby driving the puncturing member 4 to move along the first direction Z. This allows the membrane to be punctured in a direction perpendicular to the membrane, ensuring the movement accuracy of the puncturing member 4 along the first direction Z, reducing the risk of irregular puncture holes, and ensuring that all puncture holes obtained meet the testing requirements. This reduces the number of puncture holes required and improves testing efficiency.

[0040] Optionally, such as Figure 1As shown, the base assembly 1 includes a base body 11 and a support member 12 fixedly connected to the base body 11. A fixing component 2 is disposed on the base body 11, and the fixing component 2 and the support member 12 are located on the same side of the base body 11. A connecting member 31 is slidably connected to the support member 12 along a first direction Z to restrict the movement direction of the connecting member 31.

[0041] Alternatively, please continue to see Figure 1 The support member 12 includes a support rod 121 and a support block 122. The support rod 121 is fixedly connected to the base body 11. The support block 122 is sleeved on the support rod 121. In some optional embodiments, the connection position of the support block 122 on the support rod 121 is adjustable to give the base assembly 1 greater flexibility. The connector 31 is slidably connected to the support block 122 along a first direction Z.

[0042] In at least one implementation, such as Figure 4 As shown, the drive mechanism 3 also includes a transmission assembly 33, which is drively connected between the connector 31 and the drive assembly 32. The driving force of the drive assembly 32 is transmitted to the connector 31 through the transmission assembly 33 to drive the connector 31 to move in the first direction Z. By setting the transmission assembly 33, the setting position and driving direction of the drive assembly 32 can be more flexible, so that the overall size of the puncture membrane device can be smaller, which is beneficial to the miniaturization of the puncture membrane device.

[0043] In one embodiment, such as Figure 5 As shown, the transmission assembly 33 includes a gear 331 connected to the drive assembly 32 and a rack 332 connected to the connector 31. The gear 331 meshes with the rack 332, and the drive assembly 32 is rotatably mounted on the base assembly 1. For example, the drive assembly 32 is rotatably mounted on the support block 122. When the drive assembly 32 rotates relative to the support block 122 of the base assembly 1, it drives the gear 331 to rotate, and the gear 331 drives the rack 332 to move in the first direction Z, thereby driving the connector 31 to move in the first direction Z, thus realizing the transmission of power.

[0044] By setting gear 331 and rack 332, the transmission of the transmission component 33 is made more stable and reliable, and the structure of the transmission component 33 is relatively simple, making it easy to assemble and disassemble.

[0045] In some alternative embodiments, the support block 122 is provided with an inner cavity (not shown), in which the gear 331 is disposed. A portion of the rack 332 may be located within the inner cavity.

[0046] In one embodiment, such as Figure 5As shown, the rack 332 and the connector 31 are integrally formed, which improves the connection strength between the rack 332 and the connector 31. In this embodiment, the connector 31 can be a cylindrical structure with multiple toothed grooves on the side of the cylindrical structure, thereby forming both the connector 31 and the rack 332.

[0047] In other embodiments, the rack 332 and the connector 31 may not be an integral structure, but a separate structure, and the two can be connected by welding, bolting or other means.

[0048] In at least one embodiment, the connector 31 and the puncturing member 4 are able to spring back quickly after puncturing the membrane to be punctured.

[0049] Optionally, the drive mechanism 3 further includes a first elastic element. The first elastic element is disposed between the base assembly 1 and the drive assembly 32, with one end connected to the base assembly 1 and the other end connected to the drive assembly 32. When the drive assembly 32 moves in the driving direction, it can drive the connecting member 31 and the puncturing member 4 towards the fixing assembly 2 to puncture the membrane to be punctured. The first elastic element always has a tendency to drive the drive assembly 32 to move in the opposite direction of the driving direction, so that after the external force on the drive assembly 32 disappears or the driving force of the drive assembly 32 itself disappears, the drive assembly 32 can reset under the elastic force of the first elastic element, thereby causing the puncturing member 4 and the connecting member 31 to reset.

[0050] Exemplary examples show that the first elastic element includes, but is not limited to, springs, worm springs, elastic bars, etc., and this embodiment does not limit this. For example, when the first elastic element is a worm spring, the worm spring is sleeved on the drive assembly 32, and one end of the worm spring is connected to the base assembly 1, and the other end is connected to the drive assembly 32.

[0051] In some embodiments, the drive mechanism 3 further includes a second elastic element disposed between the base assembly 1 and the connector 31, with one end of the second elastic element connected to the base assembly 1 and the other end connected to the connector 31. When the connector 31 moves closer to the fixing assembly 2 along the first direction Z, the second elastic element undergoes elastic deformation. When the driving force applied by the drive assembly 32 to the connector 31 disappears, the connector 31 moves away from the fixing assembly 2 along the first direction Z to reset.

[0052] It should be noted that the drive mechanism 3 may include only the first elastic element, or only the second elastic element, or both the first elastic element and the second elastic element. This embodiment does not limit this.

[0053] In at least one embodiment, this embodiment provides a manually driven drive component 32. For example, as... Figure 4 or Figure 5 As shown, the drive assembly 32 includes a handle 321 and a rotating shaft 322. The handle 321 is located outside the base assembly 1 for easy hand gripping. One end of the handle 321 is connected to one end of the rotating shaft 322, allowing the handle 321 to move and drive the rotating shaft 322. The rotating shaft 322 passes through and is rotatably mounted on the base assembly 1. For example, the rotating shaft 322 passes through a support block 122 and through its inner cavity. The rotating shaft 322 can be rotatably mounted on the support block 122 via bearings or other components, ensuring that the rotation of the rotating shaft 322 relative to the base assembly 1 is solely its own rotation. A gear 331 is coaxially connected to the rotating shaft 322, allowing the rotating shaft 322 to rotate and drive the gear 331 to rotate.

[0054] By setting up a rotating shaft 322 and a handle 321, pressing down on the end of the handle 321 away from the rotating shaft 322 causes the rotating shaft 322 to rotate relative to the support block 122, thereby driving the gear 331 to rotate. This achieves the driving of the connecting piece 31 and the piercing piece 4 towards the fixed component 2, making the structure of the driving component 32 simpler and the reliability higher.

[0055] In some alternative embodiments, such as Figure 5 As shown, limit blocks 323 are connected to both ends of the rotating shaft 322. The limit blocks 323 are located outside the support block 122 to restrict the axial movement of the rotating shaft 322 and prevent the rotating shaft 322 from separating from the support block 122. In one embodiment, a handle 321 is fixedly connected to one limit block 323. It can be understood that there may be two handles 321, with each handle 321 corresponding to one of the two limit blocks 323.

[0056] In at least some embodiments, the first elastic element is a worm gear elastic element 34. The worm gear elastic element 34 is sleeved on the rotating shaft 322 and spaced apart from the gear 331 along the axial direction of the rotating shaft 322. One end of the worm gear elastic element 34 is connected to the rotating shaft 322, and the other end is connected to the base assembly 1. By providing the worm gear elastic element 34, when the rotating shaft 322 rotates along the direction of the drive connector 31 towards the fixed assembly 2 under the action of the handle 321, the worm gear elastic element 34 undergoes elastic deformation. When the force of the drive handle 321 disappears, the rotating shaft 322 rotates in the opposite direction under the action of the worm gear elastic element 34, thereby driving the connector 31 and the puncture member 4 to reset, achieving automatic reset of the connector 31 and the puncture member 4. For example, the worm gear elastic element 34 can be a worm spring.

[0057] It should be noted that by setting the worm elastic element 34 and gear 331 at intervals, the risk of interference between the two can be reduced, and the reliability of the drive process can be improved.

[0058] It should also be noted that the worm gear elastic element 34 is disposed in the inner cavity of the support block 122 and is fixedly connected to the inner wall of the support block 122.

[0059] In other possible implementations, the drive component 32 may also be an electric structure. For example, the drive component 32 may be an electric component such as a motor that can output torque. This embodiment does not limit this.

[0060] In at least one possible implementation, such as Figure 1 or Figure 7 As shown, the puncture membrane device also includes a limiting structure 9, which is connected to the connector 31. The limiting structure 9 and the base assembly 1 are arranged opposite each other in the first direction Z to cooperate with the base assembly 1 to limit the lower limit of the distance between the connector 31 and the fixing assembly 2. Specifically, the limiting structure 9 and the support block 122 of the base assembly 1 are arranged opposite each other in the first direction Z to further limit the minimum distance between the connector 31 and the fixing assembly 2.

[0061] By setting the limiting structure 9, the movement distance of the puncturing member 4 in the first direction Z is limited, so as to ensure that the puncturing member 4 is located below the membrane after puncturing the membrane to be punctured. This avoids the puncturing member 4 passing through too much of the membrane to be punctured, resulting in an excessively large puncture hole diameter. This ensures that the obtained puncture hole diameter is the required diameter, thereby improving the accuracy and reliability of the membrane puncture device.

[0062] For example, such as Figure 1 As shown, the limiting structure 9 is located on the side of the support block 122 facing away from the fixing component 2. When the connector 31 and the piercing component 4 move close to the fixing component 2 at the same time, the limiting structure 9 moves close to the support block 122 in the first direction Z. When the piercing component 4 pierces the membrane to be pierced and moves a preset distance relative to the membrane to be pierced, the limiting structure 9 just comes into contact with the support block 122. At this time, the connector 31 and the piercing component 4 no longer move relative to the support block 122, thus avoiding the problem of excessive movement of the piercing component 4.

[0063] Optionally, the limiting structure 9 is adjustablely connected to the connector 31 along the first direction Z, making the position of the limiting structure 9 relative to the connector 31 adjustable, thus improving the flexibility of the limiting structure 9 and meeting the needs of piercing holes of different sizes. For example, the limiting structure 9 can be a bolt, and the connector 31 has a radially extending protrusion (not shown in the figure), to which the bolt is screwed. Of course, it is understood that the limiting structure 9 can also be other structures, and this embodiment does not limit it.

[0064] Typically, at least three puncture holes need to be formed on the membrane to be punctured to meet testing requirements. Furthermore, the three puncture holes need to be spaced a certain distance apart.

[0065] In some optional embodiments, the position of the puncture membrane relative to the puncture element 4 can be adjusted by moving the fixing component 2. For example, the fixing component 2 is adjustable relative to the base component 1 in a direction perpendicular to the first direction Z. With this configuration, the position of the fixing component 2 on the base body 11 of the base component 1 is variable, so that different areas of the puncture membrane are directly opposite the puncture element 4 in the first direction Z, thereby enabling puncture holes to be created at different positions on the puncture membrane.

[0066] In at least one possible implementation, the position of the piercing element 4 relative to the puncture membrane can be adjusted by moving the piercing element 4. For example, when the base assembly 1 includes a base body 11 and a support member 12, the support member 12 is positionably connected to the base body 11 in a direction perpendicular to the first direction Z, so that the piercing element 4 can move in a direction perpendicular to the first direction Z, thereby enabling the piercing element 4 to be aligned with different areas of the puncture membrane, and realizing the creation of puncture holes at different positions of the puncture membrane.

[0067] It should be noted that the positions of the fixing component 2 and the support component 12 relative to the base body 11 are adjustable, making the entire puncture membrane device more flexible.

[0068] Optionally, the position of the fixing component 2 relative to the base body 11 can be adjusted in various ways, and this embodiment provides one possible method.

[0069] For example, such as Figure 1 As shown, the membrane rupture device also includes a first slide assembly 5 and a second slide assembly 6. The sliding direction of the first slide assembly 5 is the second direction X, and the fixing assembly 2 is disposed on the slide of the first slide assembly 5. The second slide assembly 6 is connected to the base assembly 1, and the first slide assembly 5 is connected to the slide of the second slide assembly 6. The sliding direction of the second slide assembly 6 is the third direction Y. The first direction Z, the second direction X, and the third direction Y are all perpendicular to each other.

[0070] By setting the first slide assembly 5 and the second slide assembly 6, the fixing component 2 can move in the second direction X and the third direction Y, thereby realizing the movement of the fixing component 2 relative to the base body 11. This provides high flexibility, facilitates the adjustment of the position of the fixing component 2, improves adjustment efficiency and reliability, and ensures that the distance between the puncture openings is greater than a preset value. In addition, the cooperation between the first slide assembly 5 and the second slide assembly 6 also allows for a smaller footprint.

[0071] In one possible implementation, such as Figure 6As shown, the slide of the first slide assembly 5 is provided with a limiting groove 521. The fixing component 2 can be set in the limiting groove 521. On the one hand, the limiting groove 521 can be used to limit the position of the fixing component 2 relative to the slide, and on the other hand, it can reduce the risk of the fixing component 2 falling off when the slide moves.

[0072] In at least one possible implementation, the slide of the first slide assembly 5 is referred to as the first slide 52, such as... Figure 6 As shown, the first slide assembly 5 also includes a first slide frame 51. A first slide 52 is slidably connected to the first slide frame 51 along the second direction X. A fixing component 2 is disposed on the first slide 52. The first slide frame 51 is connected to the slide of the second slide assembly 6 so that it can move in the third direction Y. Exemplarily, the first slide frame 51 is provided with an adjusting rod that extends along the second direction X and is screwed to the first slide frame 51, and is rotatably connected to the first slide 52. Rotating the adjusting rod can adjust the position of the first slide 52 relative to the first slide frame 51.

[0073] Further optional, such as Figure 6 As shown, the first slide frame 51 is provided with a first scale 53 extending along the second direction X, and the first scale 53 is provided with graduations. The first slide 52 is provided with a first indicator 54 extending toward the first scale 53. The first indicator 54 is used to indicate the graduations on the first scale 53, thereby reflecting the distance the first slide 52 moves relative to the first slide frame 51 in the second direction X. It is used to precisely adjust the movement displacement of the first slide 52 and the fixing component 2 provided on the first slide 52 in the second direction X, thereby ensuring that the distance between the two puncture holes in the second direction X is greater than or equal to a preset value (e.g., 20mm), and also ensuring the uniformity of the puncture hole distribution, that is, ensuring the uniformity of the spacing between adjacent puncture holes.

[0074] Optionally, the first indicator 54 has a tip that points to the first scale 53 so that it can be read clearly.

[0075] In at least one possible implementation, the slide of the second slide assembly 6 is referred to as the second slide 62, such as... Figure 6 As shown, the second slide assembly 6 includes a second slide frame 61 and a second slide 62. The second slide 62 is slidably connected to the second slide frame 61 along the third direction Y. The first slide frame 51 is connected to the second slide 62. The second slide frame 61 is connected to the base assembly 1. Exemplarily, the second slide frame 61 is provided with an adjusting rod. The adjusting rod extends along the third direction Y and is screwed to the second slide frame 61 and rotatably connected to the second slide 62. Rotating the adjusting rod can adjust the position of the second slide 62 relative to the second slide frame 61.

[0076] Further optional, such as Figure 6As shown, the base assembly 1 is provided with a second scale 63 extending along the third direction Y, and the second scale 63 has a graduation. The second slide 62 is provided with a second indicator 64 extending toward the second scale 63. The second indicator 64 is used to indicate the graduation on the second scale 63, thereby reflecting the distance the second slide 62 moves relative to the second slide frame 61 in the third direction Y, that is, reflecting the distance the fixing assembly 2 moves in the third direction Y. It is used to precisely adjust the movement displacement of the third slide, the first slide assembly 5 and the fixing assembly 2 in the third direction Y, thereby ensuring that the distance between the two puncture holes in the third direction Y is greater than or equal to a preset value (e.g., 20mm), and also ensuring the uniformity of the puncture hole distribution, that is, ensuring the uniformity of the spacing between adjacent puncture holes.

[0077] Optionally, the second indicator 64 has a tip that points to the second scale 63 so that it can be read clearly.

[0078] It is understandable that the fixed component 2 can also move in the second direction X and the third direction Y by means of cylinders, linear motors, etc., but this embodiment does not limit this.

[0079] In related technologies, to ensure that the direct contact between the puncturing component 4 and the diaphragm is 1mm, a 2mm thick hollow pad needs to be placed at the bottom of the diaphragm, and a glass plate is placed below the pad. Because the soldering iron cannot be controlled by hand and impacts the glass plate, the soldering iron tip is easily damaged.

[0080] In at least one embodiment, such as Figure 2 and Figure 4 As shown, this embodiment provides a fixing component 2. The fixing component 2 includes a first fixing block 21 and a second fixing block 22. The first fixing block 21 is detachably mounted on the base body 11 of the base assembly 1. For example, when a first slide assembly 5 is provided on the base body 11, the first fixing block 21 is placed in the limiting groove of the first slide 52. Furthermore, the first fixing block 21 has a first through hole 211, which extends through the first fixing block 21 along a first direction Z.

[0081] Optionally, the dimensions of the first fixing block 21 in the first direction Z range from 19mm to 23mm. For example, the dimensions of the first fixing block 21 in the first direction Z are 19mm, 21mm, 21.3mm, 23mm, etc. It should be noted that the dimension of the first fixing block 21 in the first direction Z can be referred to as the height of the first fixing block 21.

[0082] In this embodiment, the second fixing block 22 cooperates with the first fixing block 21 to clamp the membrane to be ruptured, thereby fixing the membrane. Furthermore, the second fixing block 22 has a second through hole 221 coaxial with the first through hole 211. The orthogonal projection of the piercing element 4 in the first direction Z is located within the second through hole 221 and within the first through hole 211. After the piercing element 4 passes through the second through hole 221 and punctures the membrane to be ruptured, it extends into the first through hole 211, thus avoiding contact with the first fixing block 21 and the second fixing block 22. This reduces the risk of damage due to collision between the piercing element 4 and the first or second fixing block 21 or the second fixing block 22, resulting in higher safety and reliability.

[0083] The puncture membrane usually has a diameter requirement. For example, for a diaphragm, the diameter requirement of the puncture membrane on the diaphragm is 1 mm. The diameter of the puncture membrane is related to the diameter of the tip of the puncture member 4. When the tip of the puncture member 4 is conical, it is also related to the position of the puncture member 4 relative to the connector 31.

[0084] In some alternative embodiments, such as Figure 1 and Figure 7 As shown, the puncture device also includes a gauge block 7. The base assembly 1 has a test position (not shown), which is directly opposite the puncture member 4 in the first direction Z. The gauge block 7 is selectively positioned at the test position; that is, the gauge block 7 can be located at the test position, or at other positions, such as... Figure 1 In the test position, gauge block 7 is located at a non-test position on the base body 11. The puncture component 4 is positioned opposite gauge block 7 in the test position in the first direction Z.

[0085] By setting gauge block 7, before puncturing, gauge block 7 can be placed at the test position. That is, the fixing component 2 at the test position is removed, and then gauge block 7 is placed at the test position. Then, the connection position between the puncturing element 4 and the connecting component 31 is adjusted until the tip of the puncturing element 4 contacts the top surface of gauge block 7, and then the puncturing element 4 and the connecting component 31 are fixedly connected. By adjusting the position of the puncturing element 4, the depth to which the puncturing element 4 continues to move downward after contacting the membrane to be punctured is ensured, which meets the requirement for the diameter of the puncture hole in the membrane to be punctured. Furthermore, during the test, gauge block 7 is not located at the test position, therefore, gauge block 7 will not contact the puncturing element 4 and damage the puncturing element 4.

[0086] It should be noted that when the puncture membrane device includes the first slide assembly 5, the slide of the first slide assembly 5 is located in the test position, and at this time, the gauge block 7 is set on the first slide 52.

[0087] In this embodiment, the dimension of gauge block 7 in the first direction Z ranges from 15mm to 25mm. For example, the dimensions of gauge block 7 in the first direction Z in this embodiment are 15mm, 18mm, 19mm, 19.3mm, 25mm, etc. It should be noted that the dimension of gauge block 7 in the first direction Z can be referred to as the height of gauge block 7.

[0088] For example, in this embodiment, the height of gauge block 7 is 19.3 mm. The height of the first fixing block 21 is 21.3 mm, and the standard distance between the puncture member 4 and the gauge block 7 located at the test position is ≤0.1 mm, thereby meeting the requirement that the diameter of the obtained puncture hole is 1 mm.

[0089] Optionally, such as Figure 1 or Figure 7 As shown, the puncture device also includes a housing 8, and the puncture component 4 includes a soldering iron tip. The housing 8 is connected to the base assembly 1, for example, the housing 8 is connected to the support block 122. The housing 8 surrounds the outer periphery of the soldering iron tip to isolate the high-temperature soldering iron tip, protect the operator's safety, improve the safety of the testing process, and reduce the risk of burns and punctures.

[0090] In some alternative embodiments, the housing 8 has a U-shaped structure for protection in front of and on both sides of the soldering tip.

[0091] For example, in this embodiment, the piercing element 4 is a soldering iron, which includes a soldering tip.

[0092] by Figure 1 Taking the puncture membrane device shown in the figure as an example, the usage process of the puncture membrane device provided in this embodiment is as follows:

[0093] Step 1: Connect the soldering iron to a power source, turn on the power switch, and set the temperature to 400℃. Once the temperature is reached, the red light will begin flashing; it is ready for use.

[0094] Step 2: Remove the fixing component 2 from the first slide 52. Then place the gauge block 7 on the first slide 52 and slowly press down the handle 321 to drive the soldering iron closer to the gauge block 7 via the rotating shaft 322, gear 331, rack 332, and connector 31. If the tip of the soldering iron contacts the gauge block 7, manually fine-tune the height of the soldering iron tip so that the distance between the soldering iron tip and the gauge block 7 in the first direction Z is ≤0.1mm (also known as feeler gauge test).

[0095] The third step: Remove the gauge block 7 from the first slide 52, place the first fixing block 21 of the fixing assembly 2 on the first slide 52, and limit its position using the limiting groove. Then, lay the diaphragm to be tested flat on the first fixing block 21. Next, fasten the second fixing block 22 above the first fixing block 21 to compress and flatten the diaphragm to be tested. Once everything is ready, quickly press down the handle 321, and the puncturing element 4 will puncture a hole in the diaphragm to be tested. The system uses a rack and pinion 332 and gear 331 for transmission, with a built-in spiral spring that quickly returns the handle 321 to its original position, eliminating gear 331 and rack and pinion 332 backlash errors. The puncturing element 4 has a maximum stroke of 80mm, an adjustable height of 140mm, can withstand a maximum pressure of 500Kg, and has a test depth accuracy of 0.15mm.

[0096] Step 4: Take two more puncture holes according to the test requirements, with a spacing ≥ 20mm. Visually inspect the first scale 53 or the second scale 63, and adjust the position of the first slide 52 relative to the first slide frame 51, and the position of the second slide 62 relative to the second slide frame 61 using the adjusting rod to adjust the spacing of the puncture holes. After adjustment, press down handle 321 as in Step 3 to obtain two more puncture holes. Once the test is complete and the puncture holes are confirmed to be circular, measure the area of ​​the puncture holes. The test is then complete.

[0097] The puncture device provided in this embodiment automatically presses down and then quickly rebounds away from the membrane surface to be punctured. A gauge block 7 is placed under the puncture part 4 for inspection to confirm that the requirement of "ensuring that the contact diameter between the soldering iron tip and the diaphragm is 1mm" is met.

[0098] As can be seen, the puncture device provided in this embodiment has high vertical accuracy perpendicular to the diaphragm, meeting the usage requirements. It allows the soldering tip to pierce the membrane vertically downwards and achieves rapid rebound away from the membrane after pressure. Typically, only three puncture holes are needed to meet testing requirements, improving efficiency and halving the testing time. It also reduces sampling and point-finding time, saving 5 minutes per batch. The puncture holes produced after testing are rounder than those obtained manually, meeting testing requirements and improving testing accuracy.
