Description

Technical Field

[0001] This invention relates to the field of pressure testing device technology, and in particular to a strength testing device for a new type of release film. Background Technology

[0002] Release films, as a key functional material, are widely used in industries such as electronics, printing, lamination, and die-cutting. Their performance, especially mechanical strength, tensile strength, and coating peel stability, directly affects the quality of downstream products and the smoothness of production processes. Traditional release film strength testing methods are often single-function, typically only capable of simple tensile or peel tests. They are difficult to comprehensively evaluate multiple performance indicators of the material in a single clamping and continuous process, and are difficult to simulate the complex stress states experienced by release films in actual applications, such as peeling at specific angles, local extrusion after stretching, and accurate measurement of plastic deformation. In addition, existing equipment usually requires changing fixtures or reinstalling samples when testing different parameters, which is cumbersome and inefficient. Multiple clamping may also introduce human error, affecting the accuracy and consistency of test results. Therefore, we propose a new strength testing device for release films.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves precise quantitative testing of the tensile properties and plastic deformation of release films through the cooperation of a sliding table, a lead screw, a third servo motor, a second telescopic device in the clamping structure, a clamping plate, a fourth connecting block, and a first mounting box and pressure block in the testing structure. During the testing process, the guiding structure first clamps the release film, then the second telescopic device in the clamping structure drives the clamping plate to rise, working in conjunction with the fourth connecting block to clamp another area of ​​the film. The third servo motor starts, driving the entire sliding table to move through the lead screw and sliding nut mounting seat, thereby testing the release film segment between the two clamping points. After stretching, the sliding stage resets, and the detection structure begins to work. The pressure monitoring device drives the pressure block to press down and contact the release film. By recording the displacement of the pressure block when it contacts the film, the amount of plastic deformation of the release film due to stretching can be accurately calculated. The continuous execution of this series of actions depends on the precise movement of the sliding stage, the reliable fixation of the clamping structure, and the precise measurement of the detection structure. This upgrades the traditional single tensile test to an integrated tensile-deformation test, which can more comprehensively evaluate the permanent deformation capacity of the release film after being subjected to force, providing key data for material durability.

[0014] 2. This invention achieves automated conveying and precise positioning of the release film under a stable and controlled mechanical environment through the cooperation of the first winding roller and the first servo motor in the winding structure, and the rotating roller, the third telescopic device, and the clamping block in the guiding structure. The release film roll is mounted on the first winding roller and is controlled to unwind by the first servo motor, providing a stable and adjustable initial tension for the system. During the conveying process, the release film smoothly changes direction via the rotating roller in the guiding structure, ensuring the stability and consistency of the film path. When the testing process requires positioning or state switching, the third telescopic device precisely moves, pushing the clamping block downward to stably press and fix the release film onto the second mounting box, forming... A reliable fixed endpoint is provided, and this series of automated operations avoids errors caused by manual intervention. The cooperation between the winding structure and the guiding structure, along with the second winding roller driven by the fifth servo motor, constitutes a complete closed-loop tension control system. This system can continuously apply and maintain a preset and stable longitudinal tension on the release film throughout the entire testing process, including subsequent tensile and extrusion test stages. This controlled tension environment is a prerequisite for obtaining reliable and comparable test data. It effectively simulates the tension state of the release film in actual applications, ensuring that all subsequent strength tests are conducted under consistent benchmark conditions, thereby significantly improving the accuracy and repeatability of the test results.

[0015] 3. This invention adjusts the approach angle of the test head adhered to the adhesive plate relative to the horizontal or inclined release film surface by changing the angle of the extension bracket. Simultaneously, the first telescopic device can push the sliding rod and the entire swing rod assembly to move horizontally, precisely controlling the contact position between the test head and the film. During the peel test, the adhesive plate on the rotating block is pressed against the release film surface at a set angle, and then the swing rod moves to peel the adhesive plate off the film surface. During this process, the tensile detector integrated in the rotating block records the peel force curve in real time. This adjustable angle and position design allows the device to simulate the peel state of the release film in different application scenarios, such as different tear directions, thereby obtaining peel performance data close to actual applications and accurately evaluating the uniformity and stability of the release film coating adhesion.

[0016] 4. This invention achieves rapid switching and alignment of testing stations through the movement and coordination of the sliding stage and the clamping structure, ensuring the consistency of data acquisition at different testing stages. To compare the performance changes of the release film before and after extrusion and tensile testing, it is necessary to accurately perform repeated measurements at specific locations on the film. This device, by moving the sliding stage, allows the clamping structure below it to accurately move and clamp to the position of the film segment previously clamped by the guide structure. The guide structure then moves forward and clamps the new film segment. This operation ensures that the "initial untested area" and the "tested area" can be accurately placed below the testing structure for deformation measurement. The precise displacement of the sliding stage, combined with the reliable clamping repeatability of the clamping structure, guarantees the positioning accuracy of the two tests, effectively avoiding measurement errors caused by sample position deviations. This makes the evaluation of material performance changes, such as the comparison of plasticity variables before and after extrusion, more scientific and accurate.

[0017] 5. This invention integrates tensile, extrusion, peeling, and deformation detection into a single integrated design. Under unified control, each functional structure works in an orderly manner. After the release film is clamped once, it can automatically complete a series of tests according to a preset program. First, it is fixed and stretched, and the plastic deformation is measured. Then, the peeling force is tested at different angles and positions. Finally, the performance of the tested area can be retested by moving the workstation. In the whole process, the winding and guiding structure is responsible for the stable delivery and fixation of the film, the sliding table and clamping structure is responsible for performing tensile and workstation switching, the swing rod and extrusion testing structure is responsible for complex peeling tests, and the detection structure is responsible for precise deformation acquisition, which significantly improves the detection efficiency.

Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

A fixed support frame is mounted on the bottom side of the mounting base 111 and is fixed to the ground. Two extension brackets 112, which are C-shaped frames, are rotatably mounted on the end faces of the mounting base 111. A fixed winding structure is mounted above the two extension brackets 112. A sliding platform 311 is mounted above the mounting base 111. Sliding rods 312 are mounted at both ends of the sliding platform 311. A third connecting rod is fixedly mounted between the two sliding rods 312. 313. A clamping structure is provided below the sliding table 311. Swinging rods 314 are provided on the sides of both sliding rods 312. A fixed compression test structure is provided at the end of each swinging rod 314 away from the sliding rod 312. A fixed guide structure is provided between the two mounting bases 111. A fixed fifth servo motor 711 is provided inside the mounting base 111. A second winding roller is fixedly installed at the output end of the fifth servo motor 711. A detection structure is provided above the mounting base 111. Two first sliding grooves 342 are opened on the upper side of the mounting base 111. The sides of the mounting base 111 face... Each position of the first slide groove 342 is provided with a first mounting cavity 341. A sliding nut mounting seat 344 is fixedly installed on the bottom side of the sliding table 311 corresponding to the position of the first slide groove 342. A fixed third servo motor 343 is installed inside the first mounting cavity 341. A lead screw 345 is fixedly installed at the output end of the third servo motor 343. The lead screw 345 is threaded into the interior of the sliding nut mounting seat 344. Two guide cavities 331 are provided on the side of the sliding table 311. A connecting sleeve 332 is fixedly installed on the side of the sliding table 311 corresponding to the position of the guide cavity 331. A fixed... The first telescopic device 333 has a third connecting rod 313 fixedly installed at the output end of the two first telescopic devices 333. The two ends of the third connecting rod 313 are respectively fixedly connected to two sliding rods 312. A first connecting block 322 is fixedly installed on the bottom side of the sliding rod 312. A connecting plate 323 is fixedly installed on the bottom side of the first connecting block 322. A fixing block 324 is fixedly installed on the upper side of the connecting plate 323. A second servo motor 325 is fixedly installed on the side of the fixing block 324. A rotating column 326 is fixedly installed at the output end of the second servo motor 325. A swing rod 314 is fixedly installed on the side of the rotating column 326.

[0022] More specifically, the third servo motor 343 is activated, which drives the sliding table 311 to slide via the sliding nut mounting base 344 and the lead screw 345. The first telescopic device 333 is activated, which drives the third connecting rod 313 and the sliding rod 312 to move. The sliding rod 312 drives the swing rod 314 to move. The second servo motor 325 drives the rotating column 326 to rotate, which drives the swing rod 314 to swing to control the position of the swing rod 314. During use, the release film is wound on the first winding roller 212. After passing downward through the guide structure, the release film changes 90 degrees and then passes through the clamping structure to connect to the second winding roller at the output end of the fifth servo motor 711. During testing, the release film is first clamped by the guide structure and then by the clamping structure. The sliding table 311 is moved, and the sliding table 311 moves along with the guide structure. The clamping structure moves, stretching the release film. After stretching, it returns to its initial position. At this time, the plastic deformation is detected by the detection structure. The sliding rod 312 moves, and the sliding rod 312 moves with the swing rod 314. The swing rod 314, with the extrusion test structure, extrudes the release film at the center of the extension bracket 112. At this time, both ends of the release film are fixed by the guide structure and the winding structure. The extrusion test structure applies pressure to the release film. After the extrusion is completed, the plastic deformation is also detected. Then, the sliding stage 311 is moved to a suitable position so that the position of the sliding stage 311 to the guide structure is the same as the position of the guide structure to the winding structure, and the clamping structure below the sliding stage 311 clamps the position previously clamped by the guide structure. At this time, the guide structure clamps the position where the winding structure exits. The plastic deformation after extrusion and stretching is then detected by the detection structure.

[0023] like Figure 6 As shown, specifically, the detection structure includes a first mounting box 511 that is slidably mounted on the upper side of the mounting base 111. A movable third connecting block 512 is provided below the first mounting box 511. A pressure block 513 is fixedly mounted on the bottom side of the third connecting block 512. A pressure monitoring device that drives the third connecting block 512 to move is provided inside the first mounting box 511. The pressure monitoring device is existing technology and will not be described in detail here.

[0024] More specifically, during monitoring, after the release film deforms, the pressure monitoring device drives the third connecting block 512 and the pressure block 513 to move downwards. When the pressure block 513 exerts pressure on the release film, the movement distance of the third connecting block 512 is recorded, and the deformation of the release film is determined by this distance.

[0025] like Figure 1 and Figure 4As shown, specifically, the compression test structure includes two second connecting blocks 411 fixedly installed on the end face of the swing rod 314. A rotating block 413 is arranged between the two second connecting blocks 411. A fourth servo motor 412 is fixedly installed on the side of the second connecting blocks 411. The output end of the fourth servo motor 412 is fixedly installed on the end face of the rotating block 413. The rotating block 413 is a semi-circular column. A third mounting cavity 416 is opened on the side of the rotating block 413. A fixed tensile detector 414 is arranged inside the third mounting cavity 416. An adhesive plate 415 is fixedly installed on the output end of the tensile detector 414.

[0026] More specifically, during use, the rotating block 413 moves against the release film sliding table 311, carrying the sliding rod 312. The sliding rod 312 moves the swing rod 314, which in turn moves the rotating block 413 to perform a compression test on the release film. During use, the adhesive plate 415 presses against the side of the release film. Then, the swing rod 314 moves, carrying the adhesive plate 415, and the adhesive plate 415 peels off the release film. The tension detector 414 detects and records the peeling force. The angle of the extension bracket 112 is changed to change the angle of the release film, and the force of the adhesive plate 415 peeling off the release film at different angles is detected to check whether the force curve during the entire peeling process is stable.

[0027] like Figure 8 As shown, specifically, the clamping structure includes a fourth connecting block 358 fixedly installed on the bottom side of the sliding table 311. A second mounting cavity 351 is provided on the upper side of the sliding table 311. A fixed second telescopic device 352 is provided inside the second mounting cavity 351. Two second sliding grooves 353 are provided on the upper side of the sliding table 311. A first slider 355 is slidably installed inside each of the two second sliding grooves 353. A first connecting rod 354 is fixedly installed on the upper end of the two first sliders 355. The output end of the second telescopic device 352 is fixedly installed on the bottom side of the first connecting rod 354. A clamping plate 356 is fixedly installed on the lower end of the two first sliders 355. A clamping block 357 is fixedly installed on the upper side of the clamping plate 356. A guide groove 359 adapted to the clamping block 357 is provided on the bottom side of the fourth connecting block 358.

[0028] More specifically, the second telescopic device 352 is activated, which causes the first connecting rod 354 to move upward. The first connecting rod 354 moves the two first sliders 355 upward, and the two first sliders 355 move the clamping plate 356 upward. The clamping plate 356 and the fourth connecting block 358 clamp the release film.

[0029] like Figure 1 and Figure 5As shown, specifically, the guiding structure includes a second mounting box 611 fixedly installed inside the mounting base 111. The second mounting box 611 has a rotating roller 612 inside. Two third sliders 614 are opened on the side of the second mounting box 611. A second slider 615 is slidably installed inside each of the two third sliders 614. A clamping block 617 is fixedly installed on the upper side of the two second sliders 615. A second connecting rod 616 is fixedly installed on the bottom side of the two second sliders 615. A fixed third telescopic device 613 is provided on the bottom side of the second mounting box 611. The output end of the third telescopic device 613 is fixedly installed on the side of the second connecting rod 616.

[0030] More specifically, after the release film passes through the rotating roller 612 from top to bottom, it changes angle. The third telescopic device 613 moves downward with the second connecting rod 616. The second connecting rod 616 moves downward with the second slider 615 and the clamping block 617. The clamping block 617 is used to squeeze and fix the release film.

[0031] like Figure 1 and Figure 3 As shown, specifically, the winding structure includes two connecting frames 113 fixedly mounted above two extension brackets 112, a first winding roller 212 rotatably mounted between the two connecting frames 113, a first servo motor 211 fixedly mounted on the side of the connecting frame 113, and the output end of the first servo motor 211 fixedly mounted on the end face of the first winding roller 212.

[0032] More specifically, the release film is wound around the first winding roller 212, and the other end of the release film is wound around the second winding roller at the output end of the fifth servo motor 711 to transport the entire release film.

[0033] Working Principle: First, the third telescopic device in the guiding structure actuates, pushing the clamping block downwards to press and fix one end of the release film. Simultaneously, the clamping structure below the sliding table activates, and the second telescopic device pushes the clamping plate upwards, causing its clamping block to engage with the guide groove on the fourth connecting block, firmly clamping the other area of ​​the release film. Next, the third servo motor on the side of the mounting base activates, driving the lead screw to rotate and causing the sliding table threaded to it to move horizontally. Since both ends of the release film are fixed and clamped, the movement of the sliding table stretches the film segment between the two clamping points at a constant speed or distance. After stretching, the sliding table returns to its initial position and releases the clamp. At this time, the detection structure begins to work. The pressure monitoring device in the first mounting box drives the pressure block to move downwards until it contacts the surface of the release film. The system records the displacement of the pressure block from its initial position to the point of contact with the film surface. This displacement is the amount of plastic deformation of the release film due to stretching, thereby quantitatively evaluating the material's tensile deformation resistance. An extrusion test is performed while the release film maintains a stable tension provided by the winding structure and guiding structure. The angle of the swing arm is adjusted by the second servo motor, so that the rotating block and the adhesive plate on it in the extrusion test structure are aligned with the release film test area at a specific angle. Then, the first telescopic device pushes the sliding rod and the swing arm to move towards the film surface, so that the adhesive plate is reliably pressed onto the film surface. After the pressure contact, the swing arm moves under the drive, so that the adhesive plate is peeled off from the release film surface. During this process, the tensile detector integrated inside the rotating block monitors and records the force value change in real time throughout the peeling process, thereby obtaining the peeling force curve. By changing the angle of the extension bracket or the initial angle of the swing arm, the peeling performance of the release film under different orientations can be repeatedly tested to evaluate the uniformity and stability of its coating adhesion. By precisely moving the sliding stage, the clamping structure below it clamps the film segment that was previously clamped by the guide structure, while the guide structure moves forward to clamp the new film segment. In this way, the film segment that has been subjected to extrusion and tensile tests is precisely moved to the bottom of the test structure. The deformation is measured again using the pressure block and compared with the initial state, so as to comprehensively evaluate the performance degradation of the material after complex stress.
