Description

Technical Field

[0001] This utility model relates to the field of release film performance testing equipment, and in particular to a release film adhesion testing device. Background Technology

[0002] Release film refers to a film with a distinct surface. When in contact with a specific material under limited conditions, the release film has no adhesiveness or only slight adhesiveness. In order to increase the release force of plastic films, they are usually subjected to plasma treatment, fluorine coating, or silicone release agent coating on the surface of the film material, such as PET, PE, OPP, etc., so that it can exhibit extremely light and stable release force for various organic pressure-sensitive adhesives (such as hot melt adhesives, acrylic adhesives, and rubber-based pressure-sensitive adhesives).

[0003] Release film, as a functional material with isolation properties, is widely used in industries such as electronics, packaging, and medical. During use, the adhesiveness of the release film is a key performance indicator, directly affecting its bonding effect with the substrate and the smooth progress of subsequent processing. However, existing methods for testing the adhesiveness of release films have many problems. Traditional testing devices have a relatively simple clamping structure, making it difficult to adapt to release films of different sizes and shapes, and failing to provide uniform and stable clamping. This leads to easy displacement of the release film during testing, affecting the accuracy of the test results and hindering the improvement of testing efficiency and quality. Therefore, we propose a release film adhesiveness testing device to solve the above problems. Utility Model Content

[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 1-4 In this utility model, a release film adhesion testing device includes a platform 1, a testing component 5 fixedly installed on the front of the platform 1, a clamping component 7 disposed above the platform 1, a support frame 8 fixedly connected to the back of the platform 1, a main electric push rod 9 fixedly connected to the inner wall of the support frame 8, a transmission plate 10 fixedly connected to the output end of the main electric push rod 9, and a square frame 71 fixedly connected to the outer surface of the transmission plate 10. Two transmission blocks 72 are slidably connected inside the square frame 71. A clamping plate 76 is fixedly connected to the outer surface of each transmission block 72, and a moving rod 73 is fixedly connected to the upper surface of each transmission block 72. All outer surfaces of the rod 73 are provided with fastening nuts 74. The upper surface of the square frame 71 is provided with a slot 75 that matches the moving rod 73. The table 1 provides a placement platform for testing. The testing component 5 is responsible for applying pressure and testing adhesion. The clamping component 7 automatically clamps the release film through the main electric push rod 9 and the transmission plate 10. The structure of the clamping component 7 is adjustable to adapt to the testing requirements of release films of different specifications. According to the size of the release film, the fastening nuts 74 are loosened, and the position of the transmission block 72 and the clamping plate 76 is adjusted by moving the rod 73 so that the clamping plate 76 covers the appropriate area of ​​the release film. Then the fastening nuts 74 are tightened to fix it, ensuring the stability after adjustment.

[0023] The square frame 71 has two sliding grooves 13 on its front side. A connecting rod 14 is slidably connected inside each groove 13. One end of each connecting rod 14 is fixedly connected to the upper surface of the pressing plate 76. When adjusting the position of the pressing plate 76, the connecting rod 14 slides within the groove 13, restricting the movement direction of the pressing plate 76 so that it can only move horizontally along the direction of the groove 13. When the pressing plate 76 descends to press the release film, the connecting rod 14 and the groove 13 also ensure that the pressing plate 76 moves vertically downwards, so that the release film is subjected to uniform pressure, preventing inaccurate test results due to the tilt of the pressing plate 76. The test piece 5 includes a fixed frame 51 fixedly connected to the front side of the platform 1. A secondary electric push rod 52 is fixedly connected to the inner wall of the fixed frame 51. A transmission rod 53 is fixedly connected to the output end of the secondary electric push rod 52. A pressure application plate 54 is fixedly connected to one end of the transmission rod 53. The force application plate 54 has a groove 55 inside, and a force sensor 56 is fixedly installed inside the groove 55. The auxiliary electric push rod 52, transmission rod 53 and pressure application plate 54 of the detection component 5 form a pressure application system. The force sensor 56 monitors the pressure in real time, realizing precise control of pressure and data acquisition during the release film adhesion test, ensuring the accuracy and reliability of the test data. The bottom surface of the platform 1 is fixedly connected to the support frame 2. The outer surface of the support frame 2 is fixedly installed with a touch screen 3 and a controller 4. The support frame 2 provides stable support for the platform 1, ensuring the overall stability of the detection device. The touch screen 3 and controller 4 realize human-machine interaction. The operator can input the detection parameters, start the detection program and view the detection data and results in real time through the touch screen 3. The controller 4 performs intelligent control of each component of the device, improving detection efficiency and ease of operation.

[0024] A fixed slide cylinder 6 is fixedly connected to the outer surface of the fixed frame 51. A circular slide rod 15 is slidably connected inside the fixed slide cylinder 6. A connecting plate 16 is fixedly connected to the top end of the circular slide rod 15. One end of the connecting plate 16 is fixedly connected to the outer surface of the transmission rod 53. When the auxiliary electric push rod 52 operates and pushes the transmission rod 53 to move towards the release film, the circular slide rod 15 slides inside the fixed slide cylinder 6, restricting the movement direction of the transmission rod 53 so that it can only move smoothly along the axial direction of the fixed slide cylinder 6. This ensures the stable operation of the transmission rod 53 and ensures that the pressure application plate 54 accurately and smoothly contacts the release film. The release film is formed so that the force sensor 56 can obtain accurate pressure data. Two guide rails 11 are fixedly connected to the outer surface of the support frame 8. Each guide rail 11 has a slider 12 slidably connected to its outer surface. The outer surface of each slider 12 is fixedly connected to the outer surface of the square frame 71. The guide rails 11 and sliders 12 provide guidance and support for the movement of the square frame 71, ensuring that the main electric push rod 9 drives the square frame 71 and the pressing component 7 to move smoothly during the lifting and lowering process, avoiding shaking or jamming, so that the pressing component 7 can accurately and stably press the release film.

[0025] The working principle of this utility model is as follows:

[0026] Place the release film to be tested on the stage 1, start the main electric push rod 9, which pushes the transmission plate 10 downward, causing the square frame 71 and the pressure plate 76 to descend. Loosen the fastening nut 74 according to the size of the release film, adjust the position of the transmission block 72 and the pressure plate 76 using the moving rod 73, ensuring the pressure plate 76 covers a suitable area of ​​the release film, and then tighten the fastening nut 74 to fix it. Adjust the two pressure plates 76 to the appropriate position to achieve stable pressure on the release film, preparing for subsequent testing. Then, during the release film adhesion test, control... Device 4 activates the auxiliary electric push rod 52, which pushes the transmission rod 53 and the pressure application plate 54 toward the release film, so that the pressure application plate 54 contacts the release film sample at a set pressure and holds for a certain period of time. Then, the pressure application plate 54 is moved up slowly, and the force sensor 56 collects the adhesion force data between the release film and the pressure application plate 54 in real time. At this time, the pressure data recorded by the force sensor 56, combined with other detection parameters, calculates the viscosity value of the release film and transmits the data to the controller 4. The data can be viewed through the touch screen 3 to complete the detection.
