Along the length direction of the frame 1, a loading roller 2, a first support assembly, a first cutting assembly, an optical property detection assembly, a thickness detection assembly, a second support assembly, and a discharging roller 39 are sequentially connected. A first tensioning assembly 37 is arranged between the loading roller 2 and the first support assembly, and the first tensioning assembly 37 is connected to the frame 1. A second tensioning assembly 38 is arranged between the discharging roller 39 and the second support assembly, and the second tensioning assembly 38 is connected to the frame 1.

The moving block 21 longitudinally slides in the detection frame. A displacement sensor 25 is detachably connected above the detection frame. A return spring 26 is connected between the moving block 21 and the detection frame; Then the film passes through the first rotating roller 20 and the second rotating roller 19. When the thickness of the material changes, the first rotating roller 20 will move longitudinally under pressure. The longitudinal displacement of the first rotating roller 20 is accurately measured by the displacement sensor 25. When the thickness of the film exceeds the preset range, the equipment parameters can be adjusted in time to maintain the product quality. The detection frame includes a first detection frame 23 and a second detection frame 24. The first detection frame 23 and the second detection frame 24 are detachably connected.

[0039] First, place the optical thin film on the loading roller 2. The loading roller 2 rotates, and the first tensioning assembly 37 controls the tension. The first ion bar 7 eliminates the static electricity of the passing thin film to prevent the static electricity from affecting the optical properties of the thin film or subsequent processing, and then provides stable support through the first support roller 5. The first cylinder 33 is activated, and its piston rod pushes the first connecting frame 34, which in turn drives the first pressure roller 35 to move downward. The first pressure roller 35 and the second pressure roller 36 cooperate with each other to apply appropriate pressure to the thin film located between them, ensuring the flatness of the optical thin film during the slitting process. The optical thin film enters the first cutting assembly. The cutting knife 9 rotates on the bottom plate 8 through the tool holder and cuts the thin film according to the preset cutting parameters. The temperature adjustment plate 10 embedded in the bottom plate 8 can control the ambient temperature around the cutting knife 9, enabling the optical thin film to be more easily cut while maintaining its original optical properties intact. Then, the first pressure roller 35 and the second pressure roller 36 cooperate with each other to apply appropriate pressure to the cut thin film. The cut thin film emits and receives light of a specific wavelength through the spectral detection device 17 to detect the optical properties of the cut thin film segments, and measures key optical property parameters such as the transmittance and reflectance of the thin film to ensure that the cut thin film meets the quality standards. Then, the thin film passes through the first rotating roller 20 and the second rotating roller 19. When the thickness of the material changes, the first rotating roller 20 will move longitudinally under pressure, and the longitudinal displacement of the first rotating roller 20 is accurately measured by the displacement sensor 25. When the thickness of the thin film exceeds the preset range, the equipment parameters can be adjusted in a timely manner to maintain the product quality. The thin film after thickness detection is provided with further support and guidance by the second support assembly. The second ion bar 31 eliminates the static electricity of the passing thin film to prevent the static electricity from affecting the optical properties of the thin film or subsequent processing, and the second tensioning assembly 38 controls the tension. Finally, the thin film enters the area of the unloading roller 39, and the cut thin film segments are orderly separated and guided to the next process through a plurality of distributing rollers 40 and baffles 41.
