Foam tape, as a commonly used tape, is widely used in electronics, automobiles, construction and packaging industries because of its good cushioning, sealing and adhesive properties. In these applications, the shear strength of foam tape is an important performance indicator, which determines the adhesion and retention of the tape under different environments and conditions of use. Therefore, accurate and rapid testing of the shear strength of foam tape is of great significance to product quality control and performance evaluation.

[0003] At present, the test of the shear strength of foam tape is mainly carried out by a tensile testing machine. During the test, the foam tape is fixed between two clamps, and then a gradually increasing force is applied to the clamps by the tensile testing machine until the tape breaks or separates. The force value at this time is the shear strength of the foam tape. However, this testing method has some defects. First, due to the material properties and structural characteristics of the foam tape, it will undergo a large deformation during the force process, and the existing tensile testing machine cannot accurately measure this deformation. Secondly, this testing method requires manual operation and judgment, which is not only inefficient, but also easy to introduce human errors. Finally, the existing testing method cannot achieve real-time monitoring and rapid feedback of the shear strength of the foam tape, which is very unfavorable for quality control and process adjustment in the production process. Therefore, there is a need for an accurate and reworkable foam tape shear strength testing device. Utility Model Content

[0033] An embodiment of the present application provides a reworkable foam tape shear strength testing device, which is installed on a test plate and includes an auxiliary mechanism for fixing and conveying the tape; it also includes a shearing mechanism, which is located between the auxiliary mechanisms, through which the tape is conveyed to the shearing mechanism, and the shearing mechanism is used to shear the tape; it also includes a testing mechanism, which is connected to the shearing mechanism and measures the shear strength of the tape, wherein the tape is fixed by the auxiliary mechanism, the tape is conveyed to the shearing mechanism, and the testing mechanism tests the shearing force and time of the shearing mechanism.

[0034] The above-mentioned reworkable foam tape shear strength test device is provided by firstly, the auxiliary mechanism fixes and conveys the foam tape to ensure that it is in a suitable position. Then, the foam tape is conveyed to the shear mechanism through the auxiliary mechanism, which is responsible for shearing the tape. The test mechanism is connected to the shear mechanism to measure the shear strength of the tape and record the shear force and the required time. The purpose of testing the shear strength is achieved.

[0035] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] See also Figure 1-Figure 4 The embodiment of the present application provides a reworkable foam tape shear strength testing device 100, which is installed on a test plate 10, and includes an auxiliary mechanism 20 for fixing and conveying the tape; it also includes a shearing mechanism 30, the shearing mechanism 30 is located between the auxiliary mechanisms 20, and the tape is conveyed to the shearing mechanism 30 through the auxiliary mechanism 20, and the shearing mechanism 30 is used to shear the tape; it also includes a testing mechanism 40, which is connected to the shearing mechanism 30 and measures the shear strength of the tape, wherein the tape is fixed by the auxiliary mechanism 20, the tape is conveyed to the shearing mechanism 30, and the testing mechanism 40 tests the shearing force and time of the shearing mechanism 30.

[0037] Specifically, the auxiliary mechanism 20 is mainly used to fix and transfer the tape. During the test, it ensures that the tape can be stably and accurately transferred to the shearing mechanism 30. Through the fixing and transfer of the auxiliary mechanism 20, it can be ensured that the tape will not be displaced or twisted during the test, thereby obtaining a more accurate test result.

[0038] Furthermore, the main function of the shearing mechanism 30 is to shear the tape. When the tape is delivered to the mechanism, the shearing mechanism 30 shears it, generating a shearing force. Through the precise shearing of the shearing mechanism 30, the shearing of the tape in actual use can be simulated, thereby evaluating the shear strength of the tape.

[0039] Furthermore, the testing mechanism 40 is connected to the shearing mechanism 30 and is used to measure the shear strength of the adhesive tape. It not only measures the shear force, but also records the shearing time. Through the testing mechanism 40, the relationship between the shear strength and time of the adhesive tape can be obtained, so as to understand the performance of the adhesive tape more comprehensively.

[0040] Furthermore, the foam tape to be tested is placed in the fixture of the auxiliary mechanism 20 to ensure that the tape is flat and fixed. The auxiliary mechanism 20 is started to transfer the tape to the shearing mechanism 30. When the tape reaches the shearing mechanism 30, the driving member 34 generates a driving force to move the sliding member 35, the transmission member 36 and the connecting member 33 together, thereby driving the shearing member 32 to approach the direction of the tape and complete the shearing. During this process, the testing mechanism 40 will measure and record the shearing force and time in real time. From the shearing strength. After the test is completed, the control member 60 can control the reset of the entire device to prepare for the next test.

[0041] In summary, the reworkable foam tape shear strength testing device 100 can be widely used in various scenarios where the foam tape shear strength needs to be tested. For example, on a production line, a manufacturer can use the device to perform quality inspection on each batch of foam tape to ensure that it meets the preset shear strength standard. In addition, scientific research institutions or quality inspection centers can also use the device for scientific research or product quality assessment.

[0042] In a specific implementation example, the shearing mechanism 30 includes: a protective cover 31, a shearing piece 32 and a connecting piece 33. The protective cover 31 is connected to the test board 10 and is located on the same surface of the test board 10 as the auxiliary mechanism 20; the shearing piece 32 is located in the protective cover 31 and is used to cut the tape; the connecting piece 33 is connected to the shearing piece 32 and is located in the protective cover 31.

[0043] Specifically, the protective cover 31 is connected to the test board 10 and is located on the same surface of the test board 10 as the auxiliary mechanism 20. It provides a closed working environment for the shearing member 32 to ensure that the tape will not be scattered or disturbed by the outside during the shearing process. The protective cover 31 not only improves the accuracy of the test, but also reduces the risk of the operator contacting tape debris, making the operation safer.

[0044] Furthermore, the shearing piece 32 is located in the protective cover 31 and is mainly used for cutting the tape. It is the core part for cutting the tape. The precise design and manufacture of the shearing piece 32 can ensure that the tape is accurately cut and a consistent cutting result is obtained.

[0045] Furthermore, the connecting member 33 is connected to the shearing member 32 and is located in the protective cover 31. It is mainly responsible for transmitting the movement of the shearing member 32 to the tape to achieve the shearing of the tape. The design of the connecting member 33 can ensure the stability and continuity of the shearing member 32 during the shearing process, thereby improving the reliability of the test results.

[0046] Furthermore, when the auxiliary mechanism 20 transfers the adhesive tape to the shearing mechanism 30, the adhesive tape passes through the shearing member 32. At this time, the driving member 34 generates a sliding force to drive the sliding member 35 to slide. The sliding member 35 is connected to the transmission member 36, and the transmission member 36 is connected to the connecting member 33. In this way, when the sliding member 35 slides, it drives the connecting member 33 and thus drives the shearing member 32 to approach the direction of the adhesive tape. When the shearing member 32 contacts the adhesive tape and applies a certain force, the adhesive tape is sheared. At the same time, the testing mechanism 40 measures and records the shearing force and time in real time.

[0047] In a specific implementation example, a groove 331 is formed at one end of the connecting member 33 away from the protective cover 31 , one end of the shearing member 32 is located in the groove 331 , and the other end of the shearing member 32 shears the tape.

[0048] Specifically, the groove 331 structure of the connecting member 33 away from the protective cover 31 allows more flexibility between the connecting member 33 and the shearing member 32. Due to the existence of the groove 331, the connecting member 33 can move along a certain track to ensure that the shearing member 32 can accurately approach and shear the tape. Through this groove 331, the stability and accuracy of the shearing member 32 during the shearing process can be ensured. No matter what kind of external force or stress the connecting member 33 is subjected to, it can ensure the correct position of the shearing member 32, thereby obtaining accurate test results.

[0049] Furthermore, the shearing member 32 is located in the groove 331 to ensure the stability of its position. During the shearing process, due to its close fit with the connecting member 33, it can accurately move along the predetermined track, thereby accurately shearing the tape. This design ensures the accuracy and stability of the shearing member 32 and avoids possible deviations or errors during the shearing process. This makes the test results more reliable and consistent.

[0050] Furthermore, the other end of the shearing member 32 is used to cut the tape. This is the main functional part of the shearing member 32. When the connecting member 33 is pushed by the driving member 34, this end of the shearing member 32 will contact the tape and complete the cutting action. This design ensures that the shearing member 32 can effectively complete its core task - cutting the tape. Due to its precise design and manufacturing, it can ensure consistent results every time it is cut.

[0051] In a specific implementation example, the shearing mechanism 30 further includes: a driving member 34, a sliding member 35 and a transmission member 36. The driving member 34 is located on the opposite side of the shearing member 32 to the test plate 10, and provides a sliding force; the driving member 34 drives the sliding member 35 to slide; one end of the transmission member 36 is connected to the sliding member 35, and the other end is connected to the connecting member 33, and the sliding member 35 slides to drive the shearing member 32 to approach the tape and shear.

[0052] Specifically, the driving member 34 is located opposite to the shearing member 32, and provides a sliding force for the sliding member 35. This sliding force is the key to enable the shearing member 32 to approach the tape and complete the shearing action. Through the sliding force of the driving member 34, the action of the shearing member 32 can be accurately controlled to ensure the accuracy and consistency of each shearing. This not only improves the accuracy of the test, but also makes the test more reliable.

[0053] Furthermore, the sliding member 35 is a key component connecting the driving member 34 and the transmission member 36. The driving member 34 drives the sliding member 35 to slide, and then drives the shearing member 32 through the transmission member 36. The design of the sliding member 35 makes the entire shearing mechanism 30 more compact and efficient. It ensures that the movement of the shearing member 32 is smooth and accurate without unnecessary vibration or error.

[0054] Furthermore, one end of the transmission member 36 is connected to the sliding member 35, and the other end is connected to the connecting member 33. The sliding of the sliding member 35 drives the shearing member 32 to approach the tape and complete the shearing action. The design of the transmission member 36 greatly simplifies the operation of the entire shearing mechanism 30, ensuring the efficiency and accuracy of shearing. It makes the shearing action more direct, without too many intermediate links, thereby improving the efficiency and reliability of the test.

[0055] Furthermore, when the driving member 34 starts to work, it generates a sliding force to push the sliding member 35. The sliding member 35 then transmits this force to the shearing mechanism 30 through the transmission member 36, so that the shearing mechanism 30 moves closer to the tape and completes the shearing action. This design ensures the continuity and accuracy of the shearing action, making the test results more reliable.

[0056] In a specific implementation example, the testing mechanism 40 includes a testing piece 41 , which is connected to the driving piece 34 and tests the force and time of the shearing piece 32 shearing the tape.

[0057] Specifically, the test piece 41 is a component connected to the driving member 34 and used to test the force and time of the shearing member 32 shearing the tape. It is a direct tool for measuring the shear strength of the tape. By connecting with the driving member 34, the test piece 41 can measure the force and time during the shearing process in real time and dynamically, thereby providing accurate shear strength data. This design ensures the real-time and accuracy of the test and improves the reliability of the test.

[0058] Furthermore, by connecting with the driving member 34, the test piece 41 can sense the force and time changes during the shearing process in real time, and feed back these data to the testing mechanism 40 for recording and analysis. This connection mode enables the test piece 41 to respond to the shearing action in real time, ensuring the real-time and accuracy of the measurement. It avoids measurement errors caused by time delay or data distortion.

[0059] Furthermore, the test piece 41 can accurately measure the shear force and time of the tape through its internal sensors and measurement mechanism. These are important parameters that determine the shear strength of the tape. By accurately measuring these two parameters, the physical properties and characteristics of the tape can be more accurately evaluated. This is particularly important for application scenarios such as product quality control, product development, and scientific research.

[0060] Furthermore, when the tape is sheared by the shearing mechanism 30, the test piece 41 senses the shearing force and time in real time through the connection with the driving member 34. These data are recorded by the internal mechanism of the test piece 41 and transmitted to the test mechanism 40 for further analysis and processing. This design ensures the real-time and accuracy of the shear strength measurement, making the test results more reliable.

[0061] In a specific implementation example, the auxiliary mechanism 20 includes a first clamp 21 , and is located on the same surface of the test board 10 as the auxiliary mechanism 20 . The first clamp 21 is used to clamp the tape and transfer the tape to the shearing mechanism 30 .

[0062] Specifically, the main function of the first clamp 21 is to clamp the tape and stably transfer it to the shearing mechanism 30. It ensures that the tape will not shift or slide during the transfer process, thereby ensuring the accuracy of the test. Through the clamping of the first clamp 21, the stability of the tape during the transfer process can be ensured, avoiding the test error caused by the displacement or sliding of the tape. This design improves the reliability and accuracy of the test.

[0063] Furthermore, the first clamp 21 can firmly fix the tape through its clamping function and accurately transfer it to the shearing mechanism 30. This design ensures that the tape can be stably and accurately transferred to the shearing mechanism 30, thereby avoiding various problems that may occur during the transfer process, such as displacement or sliding of the tape.

[0064] Furthermore, when the tape shear strength test is required, the first clamp 21 first clamps one end of the tape, and then stably transfers the tape to the shear mechanism 30 through its internal transfer mechanism. This process ensures that the tape will not shift or slide during the transfer process, thereby providing stable conditions for the subsequent shear test.

[0065] In a specific implementation example, the auxiliary mechanism 20 further includes a second clamp 22 , and the shearing mechanism 30 is located between the first clamp 21 and the second clamp 22 , and receives the tape transmitted and fixed by the shearing mechanism 30 .

[0066] Specifically, the main function of the second clamp 22 is to further clamp the tape after the first clamp 21 to ensure that the tape remains stable during the process of being transferred to the shearing mechanism 30 .

[0067] Furthermore, the clamping of the second clamp 22 enhances the stability of the tape during the transfer process, further avoiding the test error caused by the displacement or sliding of the tape. The second clamp 22 is located between the first clamp 21 and the shearing mechanism 30 to ensure that the tape can be stably received by the second clamp 22 and continue to be transferred to the shearing mechanism 30 after passing through the first clamp 21. By setting the second clamp 22, a stable transfer path is formed to ensure that the tape can be accurately and stably transferred to the shearing mechanism 30.

[0068] Furthermore, after receiving the tape transmitted by the shearing mechanism 30, the second fixture 22 further fixes the tape and prepares to pass it to the next component or testing mechanism 40. The receiving and fixing of the second fixture 22 provides a stable foundation for subsequent testing or processing steps, ensuring the smooth progress of the entire process.

[0069] Furthermore, after the adhesive tape is clamped and initially fixed by the first clamp 21, it is transferred to the second clamp 22 through the transmission of the shearing mechanism 30. After receiving the adhesive tape, the second clamp 22 further fixes it and then transfers it to the next testing mechanism 40 or processing step. This design ensures the stability and accuracy of the adhesive tape during the entire transfer process.

[0070] In a specific implementation example, the auxiliary mechanism 20 also includes a winding member 23 and a conveying member 24, wherein the conveying member 24 is located between the second clamp 22 and the winding member 23, and the conveying member 24 is used to further transfer the tape to the winding member 23, and the winding member 23 is used to wind the tape.

[0071] Specifically, the main function of the winding member 23 is to wind and recycle the used tape after the test is completed, so as to ensure the cleanliness of the test site and facilitate the subsequent unified treatment of the tape. By setting up the winding member 23, the used tape can be effectively managed, the tape can be prevented from being scattered at the test site, and the cleanliness and work efficiency of the test environment can be improved.

[0072] Furthermore, the conveyor 24 is located between the second clamp 22 and the winding member 23, and is responsible for transferring the tape processed by the shearing mechanism 30 from the second clamp 22 to the winding member 23. It ensures that the tape can be smoothly and stably transferred from the shearing mechanism 30 to the winding member 23 without being pulled off or stuck. The design of the conveyor 24 makes the tape more stable during the transfer process, reducing test errors or equipment failures caused by poor transfer.

[0073] Furthermore, after the adhesive tape is sheared by the shearing mechanism 30, it is temporarily fixed by the second clamp 22. Then, the conveying member 24 is activated to receive the adhesive tape from the second clamp 22 and stably convey it to the winding member 23. After receiving the adhesive tape, the winding member 23 starts to wind and recycle, and neatly winds the adhesive tape on the reel for subsequent processing.

[0074] In a specific implementation example, the reworkable foam tape shear strength testing device 100 further includes a displacement measuring component 50 , and the displacement measuring component 50 is located between the first fixture 21 and the shearing mechanism 30 , and is used to measure the shearing length.

[0075] Specifically, the main function of the displacement measuring element 50 is to measure the shear length or displacement of the tape during the tape shearing process. This helps to accurately evaluate the shearing performance of the tape and ensure the accuracy of the test. Through the displacement measuring element 50, accurate data during the tape shearing process can be obtained, providing a reliable basis for subsequent analysis and evaluation. This helps to optimize the production process of the tape and improve product quality.

[0076] Furthermore, during the tape cutting process, when the tape is cut by the cutting mechanism 30, the displacement measuring member 50 will monitor the displacement or length change of the tape in real time. Once the preset cutting length is reached, the displacement measuring member 50 will send a signal to notify the testing mechanism 40 to stop the test. This ensures that accurate cutting length data can be obtained for each test.

[0077] In a specific implementation example, the reworkable foam tape shear strength testing device 100 further includes a control member 60 . The control member 60 and the driving member 34 are located on the same surface of the test plate 10 and are used to control the conveying speed of the conveying member 24 .

[0078] Specifically, the main function of the control member 60 is to control the conveying speed of the conveying member 24. By controlling the conveying speed, the shearing process of the tape can be accurately controlled to ensure the accuracy and consistency of the shearing test. By controlling the conveying speed, the automation and standardization of the tape shearing can be achieved, and the efficiency and accuracy of the test can be improved. This helps to reduce the impact of human factors on the test results and ensure the reliability of the test results.

[0079] Furthermore, when the adhesive tape is transferred to the cutting mechanism 30 through the transfer member 24, the control member 60 will adjust the transfer speed of the transfer member 24 according to a preset program or instruction. For example, when the cutting starts, the control member 60 can gradually accelerate the transfer member 24 to ensure that the adhesive tape can be smoothly transferred to the cutting mechanism 30; after the cutting is completed, the control member 60 can gradually decelerate the transfer member 24 to reduce the cutting speed of the adhesive tape and avoid tearing or breaking of the adhesive tape during the cutting process.

[0080] Thus, the above-mentioned reworkable foam tape shear strength testing device 100 is provided by firstly, the auxiliary mechanism 20 fixes and conveys the foam tape to ensure that it is in a suitable position. Then, the foam tape is conveyed to the shear mechanism 30 through the auxiliary mechanism 20, and the latter is responsible for shearing the tape. The testing mechanism 40 is connected to the shear mechanism 30, and is used to measure the shear strength of the tape, and record the shear force and the required time. The purpose of testing the shear strength is achieved.

[0081] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
