[0020] Reference Figure 1An adhesive performance testing device includes: a support platform 100, a clamp 200, a drive device 600, and a tensile gauge 500. An adhesive sheet 150 for bonding test pieces is fixedly mounted on the support platform 100. The clamp 200 is movably mounted on the support platform 100 and is used to clamp at least a portion of the test piece. When the clamp 200 moves, it can cause at least a portion of the test piece to peel off from the adhesive sheet 150. The drive device 600 is connected to the clamp 200 and can drive it to move relative to the support platform 100. The direction of movement of the clamp 200 is parallel to the bonding plane of the adhesive sheet 150. The drive device 600 is connected to the clamp 200 through the tensile gauge 500. By integrating the support platform 100, the movable clamp 200, the drive device 600, and the tensile gauge 500, automated and precise testing of the adhesive performance of auxiliary insulating films is achieved. The support platform 100 provides stable support for the adhesive sheet 150, ensuring the reliability of the test base. The movable clamp 200 can firmly clamp the test piece and achieve stable movement under the drive device 600, simulating the peeling process in actual use, making the test pieces closer to real working conditions. The combination of the drive device 600 and the tensile gauge 500 can accurately measure the tensile force changes during the peeling process and convert them into intuitive data, providing a scientific basis for quality control and material research and development. The coordinated operation of the entire device effectively improves testing efficiency, reduces human error, ensures the accuracy and repeatability of test results, and meets the high standards required for adhesive performance testing in modern industrial production.

[0021] In some embodiments, reference is made to Figure 1 A linear transmission structure 300 is provided between the drive unit 600 and the force gauge 500, and the clamp 200 is connected to the force gauge 500 and moves linearly along with it. By setting up the linear transmission structure 300 between the drive unit 600 and the force gauge 500, the force transmission path and motion stability are further optimized. The linear transmission structure 300 eliminates unnecessary degrees of freedom during the motion process, ensuring that the clamp 200 moves strictly along a linear trajectory, thereby improving the consistency of peeling angle and speed. This precise motion control directly improves the accuracy of tensile force measurement, avoids measurement errors caused by motion deviation, ensures that each test is conducted under the same conditions, enhances the comparability and reliability of test results, and makes the evaluation of bonding performance more scientific and effective.

[0022] In some embodiments, reference is made to Figure 1The linear drive structure 300 includes a slide rail 320 and a slide block 310. The slide rail 320 is mounted on the support platform 100, and the slide block 310 is slidably mounted on the slide rail 320. The drive device 600 is connected to the slide block 310 and can drive it to slide relative to the slide rail 320. The force gauge 500 is mounted on the slide block 310. The combination of the slide rail 320 and the slide block 310 provides high-precision guiding support for the linear motion of the clamp 200. The stability and load-bearing capacity of the slide rail 320 ensure that the slide block 310 remains stable during movement, and will not wobble or tilt even when carrying a heavy force gauge 500, thus ensuring the accuracy of the peel force measurement. The connection between the slide block 310 and the drive device 600 makes motion control more direct and precise, enabling fine speed and position adjustments to adapt to the testing needs of different materials. In addition, the structure of the slide rail 320 and slide block 310 facilitates installation and maintenance, reduces the total cost of ownership of the equipment, extends its service life, ensures long-term stable operation, and provides a guarantee for continuous and reliable bonding performance testing.

[0023] Furthermore, an encoder can be installed on the slide rail 320 to accurately measure the displacement of the slide block 310, and the displacement data can be recorded synchronously with the data from the tension gauge 500 to plot a complete peel force-displacement curve, providing richer data support for in-depth analysis of adhesive performance. By analyzing the curve characteristics, the performance of the adhesive material, such as elastic modulus and yield strength, can be evaluated more accurately, providing a scientific basis for material development and process optimization.

[0024] In some embodiments, reference is made to Figure 1 The slide rail 320 is connected at both ends to the support platform 100 and the drive device 600, respectively, and the slide block 310 reciprocates between the support platform 100 and the drive device 600. The connection of the slide rail 320 at both ends to the support platform 100 and the drive device 600 forms a stable mechanical transmission chain. This arrangement ensures that the slide block 310 experiences more uniform force during its reciprocating motion between the support platform 100 and the drive device 600, reducing torsional loads and stress concentration during movement, and improving the reliability and durability of the entire mechanical system. The movement trajectory of the slide block 310 is precisely limited between the support platform 100 and the drive device 600, ensuring spatial consistency during the testing process, avoiding testing errors caused by uncertain movement ranges, further improving the repeatability and stability of the test results, and is of great significance for accurately evaluating bonding performance.

[0025] In addition, limit switches can be added to both sides of the slide rail 320 to limit the movement range of the slide block 310, preventing it from exceeding the predetermined track and causing equipment damage or testing errors. The limit switches are connected to the control system of the drive device 600. When the slide block 310 touches the limit switch, the drive device 600 immediately stops operating to ensure the safety of equipment and personnel. At the same time, by reasonably setting the position of the limit switches, the peeling length of the test piece can be precisely controlled to meet the peeling stroke requirements of different testing standards.

[0026] In some embodiments, reference is made to Figure 1 Two slide rails 320 are installed on both sides of the slide block 310, and both slide rails 320 are parallel to the bonding plane of the adhesive sheet 150. By setting two slide rails 320 connected to both sides of the slide block 310 and parallel to the bonding plane of the adhesive sheet 150, the stability of the movement and the anti-tilt capability are significantly improved. The dual slide rail 320 structure provides a wider support surface for the slide block 310, effectively resisting lateral forces and moments, ensuring that the slide block 310 will not shift or tilt when carrying the test piece, thereby ensuring the accuracy of the peel force measurement. This symmetrical mechanical support layout also helps to balance the inertial forces during the movement, reduce vibration and impact, make the movement smoother, and further improve the reliability of the test results. The dual slide rail 320 design optimizes space utilization, makes it possible to miniaturize and integrate the test device, and enhances the rigidity and load capacity of the equipment, enabling it to adapt to a wider range of test application scenarios.

[0027] It is foreseeable that an elastic buffer device, such as a spring or rubber buffer block, can be added between the slide rail 320 and the support platform 100 to absorb the impact energy during movement, reduce inertial impact caused by sudden start or stop, and improve the service life and operational stability of the equipment. The elastic buffer device can also effectively reduce vibration and noise during testing, creating a more comfortable working environment for operators, while reducing the influence of external interference on test results and improving test accuracy.

[0028] In some embodiments, reference is made to Figure 1The drive unit 600 includes a motor 610 and a screw 620. The motor 610 is connected to the slide 310 via the screw 620 and can drive its linear motion. As a power source, the motor 610 provides stable and controllable rotary motion, which, after being converted into linear motion by the screw 620, offers advantages such as stable speed and precise positioning. By precisely controlling the speed and angle of the motor 610, fine-tuning of the slide 310's speed and position can be achieved, meeting the peeling speed requirements of different testing standards. The self-locking property of the screw 620 transmission also ensures that the slide 310 remains in its position when the motor 610 stops, ensuring the continuity of the testing process and the integrity of data acquisition. This improves the automation and intelligence level of the testing device, reduces the need for manual intervention, and enhances testing efficiency and quality.

[0029] Furthermore, a gearbox can be added between the motor 610 and the screw 620 to adjust the rotational speed of the screw 620, thereby achieving stepless adjustment of the movement speed of the slide 310. The introduction of the gearbox allows the testing device to more flexibly adapt to the bonding performance testing needs of different materials, especially when testing speed-sensitive materials, enabling precise control of the peeling speed and obtaining more accurate bonding strength data. Simultaneously, the gearbox also improves the operating efficiency of the motor 610, reduces energy consumption, and enhances the energy-saving performance of the equipment.

[0030] It is conceivable that the drive unit 600 can also be composed of other components, such as direct linear drive via cylinders. The specific implementation method is not unique and can be adjusted according to actual circumstances; therefore, no restrictions are imposed here.

[0031] In some embodiments, reference is made to Figure 2 A slide bar 400 is movably mounted on the support platform 100, positioned above the adhesive sheet 150. The slide bar 400 allows the test piece separated from the adhesive sheet 150 to bend parallel to it. The movable slide bar 400 on the support platform 100 provides orderly steering and positioning guidance for the test piece after peeling. Positioned above the adhesive sheet 150, the slide bar 400 allows the peeled test piece to bend along the slide bar 400 and remain parallel to the adhesive sheet 150, preventing random scattering and entanglement of the test piece. This facilitates guiding the peeled test piece to the clamp 200 for easy gripping and maintains a clean and orderly testing environment. This design also helps reduce mutual interference among test pieces after peeling, ensuring smooth subsequent testing. Furthermore, the position of the slide bar 400 can be adjusted according to the actual size and shape of the test piece, enhancing the versatility and adaptability of the equipment and meeting the needs of testing different specifications.

[0032] In some embodiments, reference is made to Figure 3The support platform 100 is provided with two slide grooves 800, and the two ends of the slide rod 400 are slidably installed in the slide grooves 800 respectively. The length direction of the slide groove 800 is parallel to the movement direction of the clamp 200. The parallelism between the length direction of the slide groove 800 and the movement direction of the clamp 200 provides flexible positioning and guiding functions for the slide rod 400. The design of the slide groove 800 allows the slide rod 400 to be adjusted laterally according to the width of the test piece or the test requirements, ensuring that the peeled test piece can accurately slide and bend along the predetermined path, further improving the standardization of the test process and the repeatability of the results. The parallel layout of the slide grooves 800 matches the movement direction of the clamp 200, ensuring the mechanical and kinematic coordination of the entire test system, optimizing the overall performance of the test device, and enabling it to better adapt to diverse test scenarios.

[0033] In some embodiments, reference is made to Figure 3 The slide groove 800 is provided with an inner arc-shaped groove and a constriction. The slide rod 400 extends into the slide groove 800 through the constriction. A ball head 450 is provided at the end of the slide rod 400, which is movably mounted in the inner arc-shaped groove. The constriction prevents the ball head 450 from detaching from the inner arc-shaped groove. The inner arc-shaped groove and constriction design of the slide groove 800, combined with the ball head 450 at the end of the slide rod 400, form a reliable anti-detachment mechanism. The ball head 450 can move freely within the inner arc-shaped groove, ensuring smooth movement of the slide rod 400 during operation, while the constriction effectively prevents the ball head 450 from accidentally detaching, avoiding the risk of test interruption and equipment damage. This structural design not only improves the stability and reliability of the slide rod 400's movement, but the fit between the inner arc-shaped groove and the ball head 450 also allows for a certain angular deviation, increasing the system's fault tolerance and enabling the equipment to operate normally even under non-ideal conditions.

[0034] In some embodiments, reference is made to Figure 2 The fixture 200 includes jaws 230 and a threaded knob 250. The threaded knob 250 is used to adjust the tightness of the jaws 230, which can move to the support platform 100 to grip the test piece. Rotation of the threaded knob 250 precisely adjusts the tightness of the jaws 230, ensuring the test piece is firmly clamped in the fixture 200 and preventing slippage or displacement during the peeling process, thus guaranteeing the accuracy of tensile force measurement. The design of the jaws 230 allows them to move to the support platform 100 and accurately grip the test piece, simplifying the test preparation process and improving operational efficiency. Furthermore, the structure of the jaws 230 and the threaded knob 250 facilitates disassembly and replacement to accommodate test pieces of different shapes and sizes, enhancing the versatility and applicability of the equipment and meeting diverse testing needs.

[0035] In addition, an anti-slip pad made of a high-friction coefficient material, such as rubber or anti-slip cloth, is added to the inner surface of the gripper 230 to enhance the friction between the gripper 230 and the test piece, preventing the test piece from slipping during clamping and ensuring the accuracy of tensile force measurement. The shape and size of the anti-slip pad can be designed according to the shape of common test pieces, improving the versatility and stability of clamping. At the same time, the anti-slip pad is easy to replace; it can be updated promptly when worn to a certain extent, maintaining good anti-slip performance and extending the service life of the clamp 200.

[0036] It is conceivable that the clamp 200 could also be composed of other components, such as a finger cylinder. The specific implementation method is not unique and can be adjusted according to the actual situation; therefore, no restrictions are imposed here.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
