[0002] Thin films are a very special type of material, characterized by their thinness, lightness, and flexibility, making them suitable for manufacturing a wide variety of items. Puncture resistance is also one of the most important indicators of a thin film, directly affecting its durability and reliability in practical applications. This is especially crucial in scenarios requiring the film to withstand external pressure or contact with sharp objects.

[0003] To facilitate the testing of thin films and to present the test results intuitively, it is necessary to design a thin film performance testing device. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a thin film performance testing device.

[0005] The objective of this utility model can be achieved through the following technical solution: A thin film performance testing device, comprising a base, characterized in that a lower fixed platform is fixed on the base by multiple columns, one side of the lower fixed platform is hinged to one side of an upper fixed pressure plate by multiple hinges, the other side of the lower fixed platform and the other side of the upper fixed pressure plate are detachably connected by a quick clamp, the lower fixed platform has a lower clearance hole in the middle, the upper fixed pressure plate has an upper clearance hole in the middle, a water tank is fixed on the base and the water tank is located directly below the lower fixed platform, the side of the water tank is connected to one end of a water pump through a water pipe, the other end of the water pump is connected to a water pipe, a downward-sloping water injection head is connected to the water pipe, and a testing head that can move up and down is also mounted on the base by a driving assembly.

[0006] The drive assembly includes an L-shaped upright, a guide rail, a slider, and an electric cylinder. The L-shaped upright is fixed to the base, the electric cylinder is fixed to the L-shaped upright, the guide rail is vertically fixed to the L-shaped upright, the slider is slidably connected to the guide rail, a linkage frame is fixedly connected between the slider and the movable rod of the electric cylinder, and the detection head is fixed to the linkage frame.

[0007] Limiting blocks are also fixed at both ends of the guide rail.

[0008] The L-shaped upright and the reinforcing rod are fixedly connected at one end, and the other end of the reinforcing rod is fixedly connected to the water pipe.

[0009] An electrical control box is also fixed on the L-shaped upright, and the water pump and electric cylinder are electrically connected to the electrical control box via wiring.

[0010] Compared with existing technologies, this thin film performance testing device has the following advantages: In this invention, a sheet-like film is placed on a lower fixed platform and fixed by an upper fixed pressure plate. The detection head presses the film downwards, and the film forms a downward indentation after being pressed. Water is injected into the indentation of the film by a water pump to check for leakage, thereby determining whether the film has been punctured. The detection is convenient and intuitive.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figures 1-2 As shown, this film performance testing device includes a base 1. A lower fixing platform 3 is fixed to the base 1 by multiple columns 2. One side of the lower fixing platform 3 is hinged to one side of the upper fixing plate 4 by multiple hinges 19. The other side of the lower fixing platform 3 and the other side of the upper fixing plate 4 are detachably connected by a quick clamp 18. The lower fixing platform 3 has a lower clearance hole 3a in the middle, and the upper fixing plate 4 has an upper clearance hole 4a in the middle. A water tank 17 is fixed on the base 1, and the water tank 17 is located directly below the lower fixing platform 3. The water tank 17 has an opening at the top, so that if the membrane leaks during testing, water can drip into the water tank 17. The side of the water tank 17 is connected to one end of the water pump 15 via a water pipe 16, and the other end of the water pump 15 is connected to a water pipe 14. A downward-sloping water injection head 5 is connected to the water pipe 14. The base 1 is also equipped with a detection head 6 that can move up and down via a drive assembly. In this embodiment, the upper fixed pressure plate 4 can be opened to a certain angle as needed to place the membrane onto the lower fixed platform 3.

[0014] The drive assembly includes an L-shaped upright 8, a guide rail 13, a slider 11, and an electric cylinder 9. The L-shaped upright 8 is fixed to the base 1, the electric cylinder 9 is fixed to the L-shaped upright 8, the guide rail 13 is vertically fixed to the L-shaped upright 8, the slider 11 is slidably connected to the guide rail 13, and a linkage frame 7 is fixedly connected between the slider 11 and the movable rod of the electric cylinder 9. The detection head 6 is fixed to the linkage frame 7. Limit blocks 10 are also fixed at both ends of the guide rail 13. With this structure, the electric cylinder 9 can drive the linkage frame 7 to move up and down, and the linkage frame 7 drives the detection head 6 to move up and down. In practice, the detection head 6 of the required shape can be replaced as needed, which is an existing technology.

[0015] The L-shaped upright 8 and the reinforcing rod 20 are fixedly connected at one end, and the other end of the reinforcing rod 20 is fixedly connected to the water pipe 14.

[0016] An electrical control box 12 is also fixed on the L-shaped upright 8. The water pump 15 and the electric cylinder 9 are electrically connected to the electrical control box 12 through a circuit. This adopts existing technology, and its circuit does not need to be redesigned.

[0017] In this invention, a sheet-like film is placed on the lower fixed platform 3 and fixed by the upper fixed pressure plate 4. The detection head 6 presses the film downwards, and the film forms a downward indentation after being pressed. Water is injected into the indentation of the film by the water pump 15 to check for leakage, thereby determining whether the film has been punctured. The detection is convenient and intuitive.
