[0002] Adhesive tape, a widely used adhesive material in industrial production and daily life, has adhesion performance that is a core indicator for evaluating product quality. Currently, tape adhesion testing mainly includes two categories: tensile strength testing and peel strength testing, corresponding to the evaluation of the tape's cohesive strength and interfacial bond strength, respectively.

[0003] Existing tape adhesion testing equipment has the following shortcomings, such as: the testing environment is limited, conventional equipment can only test under room temperature and normal pressure conditions, and cannot simulate actual working conditions such as high temperature and special atmosphere, resulting in deviations between the test results and actual performance; the degree of automation is low, and the sample centering, surface pretreatment, and post-test cleaning rely heavily on manual operation, which is cumbersome and human factors have a significant impact on the test results.

[0015] This invention provides a tape adhesion testing platform with switchable stretch-peel modes. It comprises a testing table, a sliding rod, a sliding plate, a support base, a positioning base, a movable column, a motor, an observation box, and a cleaning box. One end of the tape to be tested is adhered to the surface of an adhesive block, while the other end is adhered to the adhesive heads at the ends of two movable columns for peel testing. Alternatively, the tape can be inserted into a clamping groove to hold both ends for stretch testing. A hydraulic lifting rod drives a pressure plate to press down, pressing and fixing the positioning base inside the support base to ensure stability of the base during testing. The motor drives a sliding block to translate along the surface of the testing support plate. One end of a pull rope is fixed inside the top seat and moves synchronously with the sliding block. The pull rope pulls the movable column to slide outward along the connecting cavity axially, subjecting the tape to an axial tensile force. The system collects tensile force values ​​in real time, and the detection head synchronously records the movement and displacement of the sliding block, thereby obtaining the tensile force and displacement curve of the tape. The magnetic head remains separated from the limiting cover, and the pull rope freely passes through the groove of the limiting cover without generating a steering force. The sliding block moves towards the support seat, causing the locking head at the end of the connecting seat to engage with the locking protrusion on the surface of the moving block. The motor continues to drive the sliding block to translate, and through the locking engagement, the slide plate and the moving block slide along the slide rod as a whole. The limiting cover is fixed to the top of the moving block and moves synchronously with it. The pull rope engages in the wire-locking groove on the top of the limiting seat, causing a steering force perpendicular to the tape's adhesive surface to be applied to the movable column, thus achieving the tape's peel strength test. The strong magnetic material on the side of the limiting cover magnetically engages with the magnetic head, allowing... After the movable column detaches, it positions itself on the surface of the limiting cover. The heating plate and heating wire inside the heating chamber are energized and heat up, raising the temperature of the testing area to simulate adhesion performance under high-temperature conditions. The gas storage chamber stores test gas, and the flow rate is controlled by a gas valve, delivering it to the testing area through the delivery port. An induced draft fan helps regulate the atmosphere. A flame generator produces a flame that is ejected through combustion holes on the side wall of the connecting chamber, allowing for flame pretreatment of the tape surface and testing the adhesion performance under different surface conditions. After testing, an electric push rod inside the cleaning chamber pushes an adjusting block to slide along the bottom of the top plate, moving the wiping mechanism to the cleaning position. A first motor drives the connecting plate to rotate and adjust the angle, and a spray head sprays cleaning fluid. A second motor drives the wiping pad to rotate, cleaning the adhesive block and adhesive residue. The adhesive residue on the head surface is wiped clean. The entire testing equipment integrates a heating module and an atmosphere control system, enabling adhesion testing at different temperatures. This more realistically simulates the actual usage conditions of the tape, making the test results more valuable. It also features a flame pretreatment function to study the impact of surface treatment on adhesive performance. Switching between tensile and peel modes is automatically completed through the translation and positioning of the sliding block, eliminating the need for manual disassembly and clamping. The switching process is quick and smooth, reducing the need for repeated sample clamping and effectively improving testing efficiency. It also avoids positioning errors introduced by manual clamping. The force gauge is directly placed on the main force path, resulting in a short force transmission path and low loss. The testing head collects the sliding block's movement distance in real time, providing high displacement detection accuracy.The device, in conjunction with a limiting plate, guides and limits the movable column, ensuring stable force direction and good repeatability and consistency of test data. Its built-in cleaning mechanism automatically cleans the bonded areas after testing, eliminating the need for manual disassembly and cleaning, reducing operational steps, and preventing damage to the test surface caused by manual cleaning, thus ensuring consistent benchmarks across multiple tests.

It includes a testing platform 1, a sliding rod 2, a sliding plate 21, a support base 3, a positioning base 4, movable columns 5, a motor 71, an observation box 8, and a cleaning box 9. One end of the tape to be tested is adhered and fixed to the surface of the adhesive block 44, and the other end is respectively adhered to the adhesive heads 51 at the ends of the two movable columns 5 for peel testing. Alternatively, the tape can be inserted into the clamping groove to clamp both ends for stretch testing. The movable column 5 is inserted into the connecting cavity 43 for initial positioning. The hydraulic lifting rod 33 drives the pressure plate 32 to press down, pressing and fixing the positioning base 4 inside the support base 3 to ensure the stability of the base during testing. The motor 71 drives the sliding block 72 along the surface of the testing support plate 12. The pull rope 50 is fixed at one end inside the top seat 75 and moves synchronously with the sliding block 72. The pull rope 50 pulls the movable column 5 to slide outward along the connecting cavity 43 axially. The tape is subjected to axial tensile force. The tension gauge 42 collects the tension value in real time, and the detection head 76 records the movement displacement of the sliding block 72 simultaneously, thereby obtaining the tensile force and displacement curve of the tape. The magnetic head 52 remains separated from the limiting cover 61. The pull rope 50 passes freely through the slide groove of the limiting cover 61 without generating a steering force. The sliding block 72 moves towards the support seat 3, so that the locking head 74 at the end of the connecting seat 73 engages with the locking protrusion on the surface of the movable block 22.

It is delivered to the test area through the delivery port 85, and the atmosphere is regulated in conjunction with the induced draft fan. The flame generated by the flame generator 45 is ejected through the combustion hole on the side wall of the connecting cavity 43, which can perform flame pretreatment on the surface of the tape and test the adhesion performance under different surface conditions. After the test is completed, the electric push rod 93 in the cleaning box 9 pushes the adjusting block 92 to slide along the bottom of the top plate 91, sending the wiping mechanism to the cleaning position.

The switching between tensile and peel modes is automatically completed by the translation and positioning of the sliding block 72, without the need for manual disassembly and replacement of fixtures. The switching process is fast and smooth, reducing the need for repeated sample clamping and effectively improving testing efficiency. At the same time, it avoids the positioning errors introduced by manual clamping. The force gauge 42 is directly set on the main force path, with a short force transmission path and low loss.

This avoids the introduction of additional force due to skewness, ensuring that the force value detected by the tensile tester 42 is the true value of the tape adhesion. The electric clamping arm automatically clamps and releases, eliminating the need for manual pressing and fixing. This results in high sample clamping efficiency and uniform clamping force, eliminating the influence of differences in manual pressing force on the test results.
