Description

Technical Field

[0001] This application relates to the field of peel force testing technology, specifically to a computer-controlled vertical peel force testing device. Background Technology

[0002] Currently, computer-controlled vertical peel force testing machines have certain limitations, mainly involving 180° or 90° vertical testing. Peel force testing at other angles requires horizontal peel force testing equipment. Furthermore, the comparability of test results for the same sample using different equipment is poor. Differences also exist in the calibration, standardization, and data analysis between different devices, ultimately leading to inconsistencies and errors in test results, affecting the accuracy and reliability of the test. Utility Model Content

[0003] To address one or more of the problems existing in the prior art, this application provides a computer-controlled vertical peel force testing device, comprising:

[0004] Supporting framework;

[0005] A tensile testing apparatus, comprising a tensile beam, an upper clamp, and sensors, wherein the two ends of the tensile beam are slidably mounted on a support frame; the sensors are mounted on the tensile beam for real-time detection of peel force; the upper clamp is mounted on the sensors for clamping the peel initiation end of the test sample; and

[0006] An angle adjustment testing device is located below a tensile testing device and includes an angle adjustment component and a lower clamp. The angle adjustment component includes an adjustment base, an angle platform, and an angle control component. One end of the angle platform is rotatably connected to the adjustment base. The angle control component is located on the adjustment base and is used to control the rotation angle of the angle platform. The lower clamp is slidably mounted on the upper surface of the angle platform via a connector and is parallel to the angle platform, used to fix the test sample.

[0007] One end of the lower clamp is fixedly connected to a guide line, and a pulley is provided on the connector. The guide line passes around the pulley and is fixedly connected to the tension beam, so that when the tension beam moves vertically upward, the lower clamp is pulled to move synchronously along the tilting platform through the guide line.

[0008] Furthermore, the tilt adjustment test device includes a movable guide rail, and the adjustment base is slidably disposed on the movable guide rail.

[0009] Furthermore, the angle control component includes a handle, a threaded rod, a support block, and a support rod. The handle is rotatably disposed at the first end of the adjustment base. The handle is connected to one end of the threaded rod, and the other end of the threaded rod is rotatably connected to the tail end of the adjustment base.

[0010] The threaded rod is fitted with the support block, and the support rod is rotatably connected to the support block. The other end of the support rod is rotatably mounted on the inclined platform.

[0011] Furthermore, the upper surface of the tilting platform is provided with a first sliding track, one end of the connector is slidably disposed in the first sliding track, and the connector is perpendicular to the tilting platform;

[0012] Preferably, the lower surface of the lower clamp is provided with a second sliding track, the other end of the connector is slidably disposed in the second sliding track, and the connector is perpendicular to the lower clamp.

[0013] Furthermore, the end of the connector near the lower clamp is connected to the end of the lower clamp near the connector by a spring.

[0014] Furthermore, the computer-controlled vertical peel force testing equipment also includes:

[0015] The processor, connected to the sensor, receives and processes the peeling force detected by the sensor, and generates a tension-displacement curve;

[0016] The display unit, connected to the processor, is used to display the force-displacement curve;

[0017] Preferably, the tilt angle adjustment test device is equipped with a magnetic electronic digital display tilt meter for real-time display of the tilt angle of the test platform.

[0018] The computer-controlled vertical peel force testing equipment provided in this application offers several significant advantages. Through its innovative tilt-adjustment testing device structure, this equipment effectively addresses the industry pain points of existing technologies, such as a single peel test angle and poor consistency of test results across different devices. Users can conveniently achieve continuous angle adjustment from 0° to nearly 180° on the same equipment and complete the test, greatly improving the comparability and accuracy of test data and avoiding systematic errors and calibration deviations caused by changing equipment.

[0019] Its unique guide line and pulley traction mechanism, along with the sliding connector and lower clamp design, ensures that the lower clamp moves smoothly and synchronously as the tension beam moves upward at any set angle. This mechanism not only guarantees the uniformity of force and the stability of direction during the peeling process, but also significantly reduces the risk of abnormal damage or premature breakage of the test sample, thereby obtaining more realistic and reliable peeling force data and providing a solid foundation for the evaluation of material interface performance.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] To make the technical problems, solutions, and advantages of this application clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described below are only some, not all, of the embodiments of this application.

[0039] This application provides a computer-controlled vertical peel force testing device, such as... Figures 1 to 3 As shown, the equipment includes a support frame 100, a tensile testing device 200, and an inclination adjustment testing device 300.

[0040] The support frame 100 is a portal frame structure, welded together from two vertical columns and a top beam. It is made entirely of high-strength aluminum alloy or carbon steel, with a rust-proof surface treatment. Precision linear guides are installed inside the columns, with a low-friction coefficient coating on the surface to ensure smooth movement of the tensile testing device.

[0041] The support frame 100 provides a rigid foundation for the equipment, and its guide rail design ensures that the tensile testing device 200 moves vertically without deviation, avoiding testing errors caused by mechanical vibration or tilting. For example, the guide rail can use ball screw or synchronous belt drive to adapt to different load requirements.

[0042] The tensile testing apparatus 200 includes a tensile beam 210, an upper clamp 220, and a sensor 230. The tensile beam 210 is slidably connected to both ends of the support frame 100 and is driven vertically by a servo motor. The servo motor has a built-in encoder, which can precisely control the movement speed (e.g., adjustable from 100-500 mm / min). The connection method and movement method of the tensile beam 210 and the support frame 100 are conventional technologies in the field, and can be adjusted as needed while ensuring smooth vertical movement of the tensile beam 210.

[0043] The tensile testing apparatus 200 has an upper clamp 220 on its tensile beam 210 for clamping the peeling start end of the test sample. The upper clamp 220 uses a pneumatic or mechanical clamping mechanism, and the clamping surface is provided with anti-slip serrations or silicone pads to ensure that the clamped part does not slip during the test.

[0044] A sensor 230 is provided between the tensile beam 210 and the upper clamp 220 on the tensile testing device 200. During the upward movement of the tensile testing device 200, the upper clamp 220 clamps the tape at the peeling start end of the test sample, thereby causing the tape to detach from the steel plate test sample. During this process, the sensor 230 can detect the peeling force in real time.

[0045] The tilt angle adjustment test device 300 is located directly below the tensile test device 200. The tilt angle adjustment test device 300 includes a horizontally placed movable guide rail 310, a tilt angle adjustment component 320, and a lower clamp 330.

[0046] The movable guide rail 310 has a double-track structure and is horizontally fixed on the equipment base 301.

[0047] The tilt adjustment component 320 includes an adjustment base 321, a tilt platform 322, and an angle control component. The adjustment base 321 is slidably mounted on the moving guide rail 310 via a track slider (not shown in the figure), so that the tilt adjustment component 320 can move horizontally relative to the equipment base 301 via the moving guide rail 310, thereby increasing the measurement range.

[0048] The tail end of the adjusting base 321 (the right end of the adjusting base 321 in the figure) is rotatably connected to one end of the tilting platform 322 via a hinge. The angle control components include a handle 323, a threaded rod 324, a support block 325, and a support rod 326. The head end of the adjusting base 321 (the left end of the adjusting base 321 in the figure) is provided with a rotatable handle 323. The handle 323 is connected to one end of the threaded rod 324, and the other end of the threaded rod 324 is rotatably connected to the tail end of the adjusting base 321. By rotating the handle 323, the threaded rod 324 can be rotated. The support block 325 is fitted on the threaded rod 324, and the support rod 326 is rotatably connected to the support block 325. The other end of the support rod 326 is rotatably positioned in the middle of the tilting platform 322.

[0049] When the handle 323 is turned, the threaded rod 324 rotates synchronously, causing the support block 325 to move from the front end of the adjusting base 321 to the rear end of the adjusting base 321, which in turn drives the support rod 326, so that the support rod 326 gradually supports the tilting platform 322 until the angle between the tilting platform 322 and the horizontal plane is adjusted to the required angle, and then the handle 323 is fixed.

[0050] The handle 323 can be fixed using screws, clips, or other designs. Simply fix it in place to indirectly fix the tilt platform 322.

[0051] The rotation direction of the handle 323 and the thread of the threaded rod 324 can be adjusted according to the actual application scenario. For example, when the handle 323 is rotated clockwise, the support block 325 engages with the threaded rod 324, causing the support block 325 to move from the front end of the adjusting base 321 to the rear end of the adjusting base 321, thereby supporting the tilting platform 322 at a certain angle (e.g., 45° to 50° or other required angles); when the handle 323 is rotated counterclockwise, the support block 325 moves from the rear end of the adjusting base 321 to the front end of the adjusting base 321, restoring the tilting platform 322 to be parallel to the plane.

[0052] The upper surface of the tilting platform 322 is provided with multiple screw holes. One end of the connector 327 can be fixed in the screw holes by means of screw fixing, and the connector 327 is perpendicular to the upper surface of the tilting platform 322.

[0053] The lower clamp 330 has a sliding rail on its lower surface. The other end of the connector 327 is slidably disposed in the sliding rail, and the connector 327 is perpendicular to the lower surface of the lower clamp 330, that is, the lower clamp 330 is arranged parallel to the tilting platform 322.

[0054] The upper surface of the lower clamp 330 is provided with screw clips 331 for fixing the test sample.

[0055] In some embodiments, the upper clamp 220 is disposed vertically downward, while the lower clamp 330 is disposed parallel to the upper surface of the tilt platform 322.

[0056] The end of the lower clamp 330 away from the connector 327 (e.g.) Figure 1 The guide line 340 is fixedly connected to the right end of the connector 327 (near the upper clamp 330). A pulley 350 is provided at one end of the connector 327 near the upper clamp 330. The guide line 340 passes through the pulley 350 and is fixedly connected to the tensile beam 210 of the tensile testing device 200. At the same time, one end of the connector 327 near the upper clamp 330 is connected to the end of the lower clamp 330 near the connector 327 (e.g., the right end of the connector 327). Figure 1 The left end of the middle is connected by spring 332.

[0057] When the tension beam 210 moves vertically upward, the guide line 340 can pull the lower clamp 330 to move obliquely from the lower right to the upper left relative to the connector 327 and the tilt platform 322. During the movement, the spring 332 is stretched until the peeling of the test sample is completed.

[0058] In some embodiments, a magnetic electronic digital display inclinometer 360 is provided on the tilting platform 322 for real-time display of the tilt angle of the tilting platform 322. The use of the magnetic electronic digital display inclinometer 360 to measure angles is conventional technology in the art, and will not be described in detail here.

[0059] In some embodiments, the computer-controlled vertical peel force testing device further includes a processor and a display unit, which work together to provide real-time monitoring and data processing capabilities for the testing process.

[0060] The processor is electrically connected to sensor 230, and its task is to receive and process the peeling force data detected by the sensor in real time. The processor has high-speed data processing capabilities and accurate algorithms, which can quickly convert the raw force signal into meaningful test results and generate detailed tension-displacement curves, which intuitively show the relationship between force and displacement throughout the peeling process.

[0061] The display unit is connected to the processor, and its main function is to display the tension-displacement curve generated by the processor to the user in a graphical way.

[0062] The workflow of the equipment provided in this application is as follows:

[0063] Rotating handle 323 causes threaded rod 324 to rotate synchronously, moving support block 325 from the front end to the rear end of adjusting base 321. This, in turn, drives support rod 326, gradually supporting tilting platform 322 until the angle between tilting platform 322 and the horizontal plane is adjusted to the required angle, such as 45°. Then, fix handle 323. At this point, since lower clamp 330 is parallel to tilting platform 322, the upper surface of lower clamp 330 is also at 45° to the horizontal plane.

[0064] The tape test sample is fixed to the lower clamp 330 by screw clip 331. At this time, the lower clamp 330 is tilted. The peeling start end of the test sample should be placed at a higher position on the upper surface of the lower clamp 330.

[0065] The tilt adjustment component 320 is moved horizontally, and the installation position of the adjusting connector 327 on the tilt platform 322 is adjusted. The tension beam 210 is moved vertically until the upper clamp 220 clamps the partially peeled adhesive tape layer at the peeling start end of the test sample, and the partially peeled adhesive tape is in a vertical state (perpendicular to the horizontal plane), as shown in the figure. Figure 3As shown, at this point, the peeled tape layer is at a 45° angle to the upper surface of the upper clamp 330, that is, the peeling angle is 45°.

[0066] The vertically upward movement of the tension beam 210 pulls the guide line 340, which in turn causes the lower clamp 330 to move relative to the connector 327 from the lower right to the upper left, stretching the spring 332. Simultaneously, the upper clamp 220 moves upward in sync with the tension beam 210, thereby continuously peeling off the test sample, and the sensor 230 continuously measures the peeling force.

[0067] After the peeling is completed, the tension beam 210 moves down, the spring 332 returns to its original state, and turning the handle 323 will restore the tilt platform 322 to horizontal.

[0068] It should be noted that the technical solutions in the various embodiments of this application can be combined with each other, but the basis for such combination is that they can be implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist, that is, it is not within the protection scope of this application.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
