[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-7 This utility model provides a technical solution: a high-speed peel test film electrostatic value tester, including a base 1, a worktable 2, a first linear module 3, a second linear module 4, a film peel test platform 5, an electrostatic test platform 6, an electrostatic value sensor 7, a mounting base 8, a force sensor 9, a guide groove 10, a guide block 11, a first magnetic block 12, a second magnetic block 13, a clamping base 14, a limiting block 15, a connecting rod 16, a drive plate 17, a guide rod 18, an electromagnet 19, a magnetic ring 20, a spring 21, a clamping plate 22, and a fixing rod 23.

[0023] A workbench 2 is fixedly installed on the upper surface of the base 1. A set of linear modules 3 is symmetrically arranged on the upper surface of the workbench 2. Another set of linear modules 4 is arranged between the linear modules 3. A film tearing test platform 5 is slidably installed on the upper surface of the linear module 4. The film tearing test platform 5 is a rectangular plate. An electrostatic test platform 6 is set above the film tearing test platform 5. The two ends of the electrostatic test platform 6 are slidably installed on the upper surface of the linear module 3. An electrostatic value sensor 7 is installed on the upper surface of the electrostatic test platform 6 through an XY axis fine adjustment slide. A mounting base 8 is fixedly installed on the upper surface of the workbench 2. A force sensor 9 is fixedly installed on the lower surface of the mounting base 8. like Figure 1 and Figure 2As shown, during the testing of the membrane material using this device, the membrane material to be tested is laid flat on the upper surface of the tear film testing platform 5. The peeling end of the membrane material is pulled to extend to the clamping seat 14, thereby limiting the peeling end of the membrane material. The second linear module 4 is activated, driving the tear film testing platform 5 to slide at a constant speed along the extension direction of the second linear module 3. At the same time, the first linear module 3 is activated, and the position of the electrostatic testing platform 6 is adjusted according to the testing requirements so that the electrostatic value sensor 7 is always aligned with the testing area of ​​the membrane material. The electrostatic value data of the membrane material during the high-speed peeling process is collected in real time and transmitted to the data processing system. During the movement of the membrane material driven by the tear film testing platform 5, the peeling end of the membrane material is fixed and limited by the clamping structure, generating peeling tension. This tension is transmitted to the force sensor 9 through the clamping seat 14. The force sensor 9 collects the tearing force data during the peeling process in real time and transmits it synchronously to the data processing system, realizing the synchronous testing of electrostatic value and tearing force.

[0024] The side surface of the mounting base 8 is provided with a clamping structure. The clamping structure achieves clamping and limiting of the peeling end of the film material through the moving limiting block 15. The clamping structure includes a clamping seat 14, which is C-shaped and connected to the force sensor 9. The limiting block 15 is slidably installed on the inner wall of the clamping seat 14. The upper surface of the limiting block 15 is fixedly connected to the lower end of the connecting rod 16. The upper end of the connecting rod 16 slides through the upper surface of the clamping seat 14. Three connecting rods 16 are arranged in parallel. The three connecting rods 16 are fixedly connected to the side surface of the same drive plate 17. The drive plate 17 slides through the outer surface of the guide rod 18. The lower end of the guide rod 18 is fixedly installed on the upper surface of the mounting base 8. The outer surface of the guide rod 18 is sleeved with... There is an electromagnet 19 and a magnetic ring 20. The electromagnet 19 is fixedly connected to the guide rod 18. The magnetic ring 20 is fixedly installed on the upper surface of the drive plate 17. The magnetic poles of the electromagnet 19 and the magnetic ring 20 repel each other. A spring 21 is provided on the outer surface of the guide rod 18. One end of the spring 21 is fixed to the lower surface of the drive plate 17, and the other end of the spring 21 is fixedly installed on the upper surface of the mounting base 8. The upper surface of the film tearing test platform 5 is provided with four clamping plates 22 in a rectangular shape. The surface of the clamping plate 22 is provided with rounded rectangular through holes. A fixing rod 23 is provided through the through holes on the surface of the clamping plate 22. The fixing rod 23 is T-shaped and the lower end of the fixing rod 23 is a threaded rod structure. The fixing rod 23 is threadedly connected to the surface of the film tearing test platform 5. like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the specific process of clamping and installing the membrane material is as follows: The membrane material to be tested is laid flat on the upper surface of the tear test platform 5. The clamping plate 22 covers the edge fixing area of ​​the membrane material. The fixing rod 23 passes through the rounded rectangular through hole on the surface of the clamping plate 22 and is threadedly connected to the tear test platform 5, so that the clamping plate 22 is pressed tightly against the surface of the membrane material, achieving the limiting of the membrane material. The position of the clamping plate 22 can be finely adjusted using the rounded rectangular through hole on the surface of the clamping plate 22 to adapt to membrane materials of different sizes and thicknesses. The peeling end of the membrane material is pulled to extend it to the clamping seat 14. The internal area is positioned so that the peeling end of the film material is directly below the limiting block 15. When the electromagnet 19 is activated, it forms a magnetic pole repulsion force with the magnetic ring 20 on the upper surface of the drive plate 17, pushing the drive plate 17 to slide downward along the guide rod 18. At this time, the spring 21 is compressed. When the drive plate 17 moves downward, it drives the limiting block 15 to slide downward synchronously on the inner wall of the clamping seat 14 through the connecting rod 16 until the lower surface of the limiting block 15 is tightly attached to the peeling end of the film material. By utilizing the cooperation between the limiting block 15 and the inner wall of the clamping seat 14, the peeling end of the film material is clamped and limited.

[0025] The lower surface of the workbench 2 is provided with a guide and anti-deviation structure. The guide and anti-deviation structure guides and prevents deviation during the sliding process of the film tearing test platform 5 through the guide groove 10 and the guide block 11. The guide and anti-deviation structure includes the guide groove 10, which has a concave cross-section. The lower surface of the guide groove 10 is fixedly installed on the upper surface of the workbench 2. The upper surface of the guide groove 10 is slidably installed with the guide block 11, which is T-shaped. The upper surface of the guide block 11 is fixedly installed on the lower surface of the workbench 2. There are two guide grooves 10 symmetrically arranged. The surfaces of the two guide grooves 10 are respectively provided with guide blocks 11 and fixedly connected to the lower surface of the workbench 2. The upper surface and bottom surface of the guide groove 10 are respectively fixedly installed with a first magnetic block 12. The first magnetic block 12 is aligned above the first magnetic block 12. The second magnetic block 13 is fixedly installed on the lower surface of the guide block 11. The magnetic poles of the first magnetic block 12 and the second magnetic block 13 repel each other. like Figure 2 , Figure 3 and Figure 4 As shown, when the tear film test platform 5 slides on the upper surface of the second linear module 4, the guide block 11 slides in the guide groove 10 along with the tear film test platform 5. The movement trajectory of the tear film test platform 5 is restricted by the cooperation between the guide groove 10 and the guide block 11 to avoid deviation. At the same time, the magnetic pole repulsion between the first magnetic block 12 on the upper surface of the guide groove 10 and the second magnetic block 13 on the lower surface of the guide block 11 can reduce the friction during the sliding process of the guide block 11, reduce the wear of the guide block 11, and ensure the stability of the test process.

[0026] Working principle: When using this high-speed peel test film electrostatic value tester, the film to be tested is laid flat on the film peel test platform 5. The edge of the film is pressed by the threaded connection between the clamping plate 22 and the fixing rod 23. The peeling end of the film is pulled to the clamping seat 14. The electromagnet 19 is energized and generates a repulsive force with the magnetic ring 20, which pushes the drive plate 17 to move down. The connecting rod 16 drives the limit block 15 to press the film. The first linear module 3 is started to adjust the position of the electrostatic test platform 6. The electrostatic value sensor 7 is aligned with the test area by the XY axis fine adjustment slide. During this process, the guide block 11 and the guide groove 10 cooperate to guide, and the first magnetic block 12 and the second magnetic block 13 repel each other to reduce friction, ensuring that the film peel test platform 5 slides smoothly along the second linear module 4. The film peel test platform 5 drives the film to peel off at high speed. The electrostatic value sensor 7 collects electrostatic data in real time, and the force sensor 9 obtains the film peeling force data synchronously through the clamping seat 14. Both are transmitted to the data processing system to complete the synchronous test, which increases the overall practicality.
