Description

Technical Field

[0001] This utility model relates to the field of testing and measurement technology, and in particular to an integrated system for measuring film thickness, air permeability and puncture performance. Background Technology

[0002] The statements in this section merely provide background information related to this utility model and do not necessarily constitute prior art.

[0003] For testing the air permeability of lithium battery separator materials, an air permeability tester is often used, while a corresponding electronic tensile testing machine is used for puncture testing, and there are also specialized thickness testers for thickness testing. However, in the actual testing process of separators, it is necessary to distinguish batch information and obtain test data at once. If the three test properties of the separator are tested separately, samples need to be prepared separately for testing, and the test data needs to be sorted out in batches, which is not only time-consuming and labor-intensive, but also prone to errors in the data statistics process.

[0004] Currently, most commercially available systems use automated sample feeding systems to perform the three tests mentioned above. This involves setting up three different testing instruments on the system, preparing samples of uniform length and width, gripping and placing the samples for testing, and then automatically feeding the samples at set distances for further testing until the entire sample is tested. Data from air permeability, puncture, and thickness tests can be unified onto the automated sample feeding system. For example, patent number CN119470200A discloses an automated testing device and method for lithium-ion battery separator performance. It uses an automated assembly line approach to achieve multi-functional testing of thin-film samples. However, although it integrates many functions, its overall structure is complex, its overall cost is high, and it occupies a large testing space. Furthermore, the testing platforms for each functional module are not uniform, and the samples are large and relatively soft, making it difficult to ensure sample flatness during testing. This increases the testing errors of each functional module and reduces the accuracy of the test results. Utility Model Content

[0057] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0058] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0059] In this implementation, an integrated system for measuring film thickness, air permeability, and puncture performance is proposed, such as... Figure 1 As shown, it includes: base assembly 1, test platform assembly 2, scanner assembly 3, driven roller assembly 4, puncture test assembly 5, air permeability test assembly 6, thickness test assembly 7, active roller assembly 8, and housing assembly 9.

[0060] The base assembly 1 provides stable support and is internally equipped with a first pressure regulating valve and pressure controller, enabling fixed pressure or flow control for testing the air permeability of the sample. The test platform assembly 2 provides the sample testing position, allowing air permeability, puncture, and thickness measurement functions to be tested simultaneously on the same platform. The scanner assembly 3 can scan the barcode attached to the sample, which contains information such as the diaphragm type, production line, batch number, and size specifications, which can be fed back to the control terminal for convenient sample information statistics. The driven roller assembly 4 mainly presses down on the end of the sample during sample injection, providing a certain amount of damping to ensure the sample is tested smoothly on the test platform. The puncture test assembly 5 is mainly used to perform puncture tests on the sample. After the cylinder clamps the sample, a force sensor and a puncture needle are installed on the linear module to perform puncture tests on the sample. The air permeability test assembly 6 is mainly used to perform air permeability tests on the sample. It also uses a cylinder to clamp the sample and sets a pressure or flow rate that meets the standard to judge the air permeability performance of the sample. The thickness test assembly 7 is mainly used to perform thickness tests on the sample. It is equipped with a pneumatic lifting device, which allows the linear displacement sensor to be lifted and lowered under pneumatic action to complete the thickness test of the sample. The active roller assembly 8 is mainly used to rub and inject the sample. The pressure between the upper and lower active rollers is adjusted by adjusting the matching second pressure regulating valve, so that the upper and lower rollers clamp the sample for rubbing and injecting.

[0061] like Figure 2 As shown, the base assembly 1 includes a base plate 1.1, a base plate housing 1.2, a temperature and humidity sensor 1.3, a first pressure regulating valve 1.4, a pressure controller 1.5, a main control board 1.6, and a solenoid valve assembly 1.7. The base plate housing 1.2 is fixed on the base plate 1.1. The temperature and humidity sensor 1.3 is fixed on the base plate 1.1 via a connector. The first pressure regulating valve 1.4, the pressure controller 1.5, the main control board 1.6 (equipped with a main controller), and the solenoid valve assembly 1.7 are all fixed on the base plate 1.1. The temperature and humidity sensor 1.3 can display the ambient temperature and humidity in real time. The first pressure regulating valve 1.4 can be adjusted to the pressure regulation range of the pressure controller 1.5 to meet usage requirements. The main controller on the main control board 1.6 can control the solenoid valve assembly 1.7 to realize the action of each part of the drive mechanism.

[0062] like Figure 3 As shown, the test platform component 2 includes a platform plate 2.1 and a test platform 2.2. The test platform 2.2 is mounted on the platform plate 2.1. On the upper plane of the test platform 2.2, there are circular holes (i.e., puncture test holes and air permeability test holes) for testing puncture area and air permeability area.

[0063] like Figure 4As shown, the scanner assembly 3 includes a scanner mounting plate 3.1 and a scanner 3.2. The scanner 3.2 is mounted on the scanner mounting plate 3.1, and the scanner mounting plate 3.1 is installed inside the housing 9.1. The scanning port of the scanner 3.2 is exposed through the opening of the housing 9.1.

[0064] like Figure 5 As shown, the driven roller assembly 4 includes a fixed base 4.1, a top plate 4.2, a cylinder 4.3 (i.e., the driven roller drive mechanism, which can also be a hydraulic cylinder or electric cylinder or other linear drive mechanism), guide rods 4.4, an upper driven roller seat 4.5, an upper driven roller 4.6, and a lower driven roller 4.7. The fixed base 4.1 is fixed on the platform plate 2.1. Two guide rods 4.4 (or more guide rods 4.4, which will not be described in detail here) pass through the protruding ends of the fixed base 4.1. The upper part of the guide rods 4.4 is connected to the top plate 4.2, and the lower part of the guide rods 4.4 is connected to the upper driven roller seat 4.5. The upper driven roller 4.6 is connected to the upper driven roller seat 4.5. Cylinder 4.3 is fixed to the lower part of the extended end of the fixed base 4.1. Cylinder 4.3 is arranged between the two guide rods 4.4. When the output shaft of cylinder 4.3 extends, it can press against the top plate 4.2, thus lifting the upper driven wheel 4.6. When the output shaft of cylinder 4.3 retracts, the upper driven wheel 4.6 will descend under the action of gravity to contact and clamp the sample with the lower driven wheel 4.7. The lower driven wheel 4.7 is fixed on the fixed base 4.1, and its outer ring is kept at the same horizontal height as the test platform 2.2 (that is, the horizontal tangent of the uppermost part of the outer ring is coplanar with the upper surface of the test platform 2.2). This ensures that the sample remains flat when the two driven wheels clamp the sample.

[0065] like Figure 6 As shown, the puncture assembly 5 includes a pressure cylinder 5.1 (i.e., the fourth pressure drive mechanism, which can also be a hydraulic cylinder or electric cylinder or other linear drive mechanism), a pressure plate 5.2, a linear module seat 5.3, a linear module 5.4 (i.e., the first pressure drive mechanism, which can also be a hydraulic cylinder or electric cylinder or other linear drive mechanism), a force sensor seat 5.5, a force sensor 5.6, and a puncture needle 5.7; the pressure cylinder 5.1 is connected to the pressure plate 5.2 and is fixedly connected to the test platform 2.2, during the test... After the sample is placed on platform 2.2, the pressing cylinder 5.1 is activated, causing the pressing plate 5.2 to press down on the sample. The linear module seat 5.3 is fixed on the platform plate 2.1, and the linear module 5.4 is fixed on the linear module seat 5.3. The linear module 5.4 is connected to the force sensor seat 5.5 and the force sensor 5.6. The puncture needle 5.7 is fixed at the lower end of the force sensor 5.6. When the linear module 5.4 moves downward, it will drive the puncture needle 5.7 to move downward, thereby completing the puncture test of the sample.

[0066] like Figure 7As shown, the air permeability test assembly 6 includes an air permeability cylinder 6.1 (i.e., the second downward pressure drive mechanism, or other linear drive mechanisms such as hydraulic cylinders or electric cylinders) and an upper air permeability chamber 6.2. The air permeability cylinder 6.1 is installed under the fixed base 8.1, and the upper air permeability chamber 6.2 is connected to the air permeability cylinder 6.1. The upper air permeability chamber 6.2 extends outward from the extension shaft of the air permeability cylinder 6.1, so that the upper air permeability chamber 6.2 presses down on the sample on the test platform 2.2. Then, the pressure required by the standard is set through the pressure controller 1.5, and the change of its flow rate is detected, thereby obtaining the air permeability performance of the test sample.

[0067] like Figure 8 As shown, the thickness testing assembly 7 includes a thickness measuring cylinder 7.1 (i.e., the third downward driving mechanism, which can also be a hydraulic cylinder or electric cylinder or other linear drive mechanism), a thickness measuring cylinder base 7.2, a connecting plate 7.3, and a linear displacement sensor 7.4. The thickness measuring cylinder base 7.2 is fixed below the fixed base 8.1, and the thickness measuring cylinder 7.1 is fixed on the thickness measuring cylinder base 7.2. The connecting plate 7.3 is fixed to the shaft end of the thickness measuring cylinder 7.1. The connecting plate 7.3 has a U-shaped opening that passes through the lower end of the linear displacement sensor 7.4. When the thickness measuring cylinder 7.1 retracts upward, the connecting plate 7.3 drives the linear displacement sensor 7.4 to lift upward. When the thickness measuring cylinder 7.1 extends downward, the linear displacement sensor 7.4 moves downward under the pressure of its built-in spring. Before placing the sample, the linear displacement sensor 7.4 moves downward, and its probe contacts the testing platform 2.2, setting it to zero. Then it lifts up, places the sample, and continues to move downward, thus obtaining the sample thickness value.

[0068] like Figure 9As shown, the active roller assembly 8 includes a fixed base 8.1, a motor 8.2, a motor base 8.3, a lower active roller 8.4, an upper active roller 8.5, an upper active roller seat 8.6, an active roller cylinder 8.7 (i.e., the active roller drive mechanism, which can also be a hydraulic cylinder or electric cylinder or other linear drive mechanism), and a second pressure regulating valve 8.8. The fixed base 8.1 is fixed on the platform plate 2.1, the motor 8.2 is fixed on the motor base 8.3, and the motor base 8.3 is fixed below the fixed base 8.1. The lower active roller 8.4 is directly connected to the motor 8.2. The active roller cylinder 8.7 is fixed to the extended end of the upper part of the fixed base 8.1 and connected to the upper active roller seat 8.6. The upper active roller seat 8.6 is connected to the upper active roller 8.5. The axes of the upper active roller 8.5 and the lower active roller 8.4 are on the same vertical plane, so that the active roller... When the cylinder 8.7 moves downward, the lower active roller 8.4 and the upper active roller 8.5 come into contact. The outer ring of the lower active roller 8.4 is kept on the same horizontal plane as the test platform 2.2 (i.e., the horizontal cross-section of the uppermost part of the outer ring is coplanar with the upper surface of the test platform 2.2). When the sample is placed on the lower active roller 8.4, the upper active roller 8.5 will press down on the sample. The required pressure can be adjusted by the second pressure regulating valve 8.8 installed on the housing 9.1 (the second pressure regulating valve 8.8 is connected to the active roller cylinder 8.7 through a pipeline, and the second pressure regulating valve 8.8 is exposed through a through hole on the housing 9.1 for easy adjustment). Because the lower active roller 8.4 is directly connected to the motor 8.2, controlling the operation of the motor 8.2 will drive the lower active roller 8.4 to rotate. Under the action of friction, the sample will be rubbed and horizontally injected.

[0069] In this implementation, the housing component 9 includes a housing 9.1 and a control terminal 9.2 with a display module. The control terminal 9.2 is installed at the front end of the housing 9.1, and the housing 9.1 is installed on the platform board 2.1. The control terminal 9.2 can collect relevant test data information.

[0070] The specific operating principle of the above-mentioned integrated film thickness, air permeability and puncture performance measurement system is as follows:

[0071] Prepare the sample, cut a membrane sample of a certain length and width, and print out a QR code or barcode, and affix it to the end of the sample;

[0072] Clean the upper surface of the test platform 2.2 to ensure its cleanliness. Operate the control terminal software 9.2 and control the solenoid valve group 1.7 through the main control board 1.6 to activate cylinders 4.3, 5.1, 6.1, 7.1, and 8.7. This causes the upper driven roller 4.6, lower pressure plate 5.2, upper ventilation chamber 6.2, linear displacement sensor 7.4, and upper active roller 8.5 to all rise. Simultaneously, the linear module 5.4 moves upward under the control of the control terminal software 9.2, moving the puncture needle 5.7 to the appropriate position.

[0073] The operation control terminal 9.2 causes the thickness measuring cylinder 7.1 to move, so that the probe of the linear displacement sensor 7.4 contacts the test platform 2.2, and then sets its value to 0. Then the linear displacement sensor 7.4 is lifted.

[0074] Use scanner 3.2 to scan the QR code or barcode on the end of the prepared sample so that the software can read the relevant data information of the sample. Then flatten the sample and place it on the test platform 2.2. One end of the sample needs to pass through the lower active roller 8.4 to ensure that the upper active roller 8.5 can press down on the sample.

[0075] At the start of the test, the active roller cylinders 8.7 and 4.3 activate, pressing the sample at both ends of the equipment to ensure its flatness. Then, the thickness measuring cylinder 7.1 is activated, and the probe of the linear displacement sensor 7.4 contacts the sample downward to obtain its thickness value. The linear displacement sensor 7.4 is then lifted, and the venting cylinder 6.1 presses down to hold the sample in place. According to the standard test pressure set by the pressure controller 1.5, the flow rate or volume through the sample is fed back to obtain its air permeability. The venting cylinder 6.1 then retracts, and the pressing cylinder 5.1 continues to hold the sample in place. The linear module 5.4 moves downward, driving the force value sensor 5.6 and the puncture needle 5.7 to puncture downward. After obtaining the puncture force value, both the pressing cylinder 5.1 and the linear module 5.4 return to their original positions.

[0076] Then, the motor 8.2 drives the lower active roller 8.4 to rotate. Under the action of friction, the film sample is moved horizontally and fed in. After reaching the set distance, the motor 8.2 stops rotating, and then the thickness test at the next position is carried out (the thickness test must be carried out first, and the puncture or air permeability test cannot be carried out at the same time to avoid affecting the thickness test results). The test is carried out at multiple positions in sequence until all samples are tested.

[0077] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
