Description

Technical Field

[0001] The utility model relates to the technical field of optical films, in particular to a multi-layer laminating device for optical films. Background Art

[0002] Optical film is a type of optical medium material that is composed of thin layered media and transmits light beams through interfaces. At present, optical thin films have been widely used in the fields of optics and optoelectronics to manufacture various optical instruments. The characteristics of optical thin films are: smooth surface, geometrically divided interfaces between film layers; the refractive index of the film layer can jump at the interface, but it is continuous within the film layer; it can be a transparent medium or an absorbing medium; it can be normal uniform or normal non-uniform. The actual application of thin films is much more complicated than the ideal film. The optical and physical properties of the film deviate from the bulk material, and its surface and interface are rough, which leads to diffuse scattering of the light beam; the mutual penetration between the film layers forms a diffusion interface; the anisotropy of the film is formed due to the growth, structure, stress and other reasons of the film layer; the film layer has a complex time effect.

[0003] For example, the patent document with application number 202120346500.6 discloses an optical film laminating device, and the utility model discloses an optical film laminating device in the field of optical film technology, including: a handle, a support frame structure is installed on the lower wall surface of the handle, a scraper structure is installed on the left wall surface of the support frame structure, a pressure roller structure is installed on the left wall surface of the scraper structure, a winding structure is installed on the lower wall surface of the support frame structure, a cleaning structure is installed on the lower wall surface of the support frame structure, and a power structure is installed on the front wall surface of the support frame structure; the support frame structure includes: a winding support frame, a cleaning support frame, and a support frame connection. The utility model integrates the steps of using the existing optical film and realizes the integrated work process of cleaning, applying, leveling and compacting, which greatly improves the efficiency of the optical film in use and makes the use of the optical film no longer limited to professionals and professional equipment. This greatly reduces the threshold for the use of optical films and greatly improves the scope of application of optical films. However, when the optical film is laminated and multiple layers of optical film are required to be applied, the scraper cannot accurately control the height of the scraper, so the optical film cannot be well scraped and applied, which will cause bubbles to remain in the film.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a multi-layer laminating device for optical films is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, a multi-layer laminating device for optical films includes a winding shaft body 1, a handle 101 is installed at the upper end of the winding shaft body 1, and a connecting plate 102 is arranged at the rear end of the winding shaft body 1. This arrangement is an existing device and will not be described in detail.

[0024] Furthermore, a support frame 2 is provided at the front end of the connecting plate 102, and a threaded transmission rod 201 is spirally installed on the upper end surface of the support frame 2, and an adjustment knob 202 is installed on the upper end of the threaded transmission rod 201. The advantage of this arrangement is that through the arrangement of the threaded transmission rod 201, the height of the scraper 203 can be adjusted through spiral transmission, so that the height of the scraper 203 can be adjusted according to the different layers of optical films, thereby improving the adaptability of the scraper 203 and avoiding residual bubbles in the film.

[0025] Furthermore, a scraper 203 is provided at the lower end of the threaded transmission rod 201, and sliding limit rods 204 are installed on both sides of the upper end surface of the scraper 203, and the sliding limit rod 204 is slidably connected to the support frame 2. The advantage of this arrangement is that the scraper 203 can be limited by the setting of the sliding limit rod 204 to prevent the scraper 203 from being offset.

[0026] like Figure 3-Figure 4 As shown, a support frame 2 3 is installed at the rear end of the support frame 1 2, and a sliding groove 301 is opened on the inner wall surface of the support frame 2 3, a sliding block 304 is slidably installed inside the sliding groove 301, and a pressure roller 305 is arranged at the front end of the sliding block 304. The advantage of this arrangement is that the pressure roller 305 can be limited by the arrangement of the sliding block 304, so that the pressure roller 305 can slide up and down stably.

[0027] Furthermore, a buffer spring 303 is installed at the upper end of the sliding block 304, and a telescopic rod 302 is installed inside the buffer spring 303. The advantage of this arrangement is that, through the arrangement of the buffer spring 303, when the downward pressure is too large, the downward pressure of the optical film can be reduced by compressing the buffer roller 305, thereby avoiding damage to the optical film caused by excessive downward pressure of the pressure roller 305.

[0028] Furthermore, a support frame 3 4 is installed at the front end of the winding shaft body 1, and a vacuum cleaner 403 is installed at the upper end of the support frame 3 4, a dust storage box 404 is arranged at the rear end of the vacuum cleaner 403, and a stretching drawer 405 is slidably installed inside the dust storage box 404. The advantage of this arrangement is that, through the arrangement of the vacuum cleaner 403, after the felt roller 402 has cleaned the dust, the fine dust on the surface to be applied can be adsorbed to avoid contact between impurities and the optical film, and through the arrangement of the stretching drawer 405, the dust inside the dust storage box 404 can be easily removed.

[0029] Furthermore, a driving device 401 is installed on one side surface of the support frame 3 4 and a felt roller 402 is provided at the output end of the driving device 401. This setting is an existing device and will not be described in detail.

[0030] Working principle: When using the multi-layer laminating device for optical film, first, push the handle 101 to drive the reel body 1 to move forward, start the driving device 401 at the front end of the reel body 1 to drive the felt roller 402 to roll and clean the dust at the position where the film needs to be applied, and at the same time, start the vacuum cleaner 403 to absorb the fine dust at the application position after the felt roller 402 passes by. After the optical film of the reel body 1 is applied, the height of the scraper 203 is adjusted by controlling the adjustment knob 202 to drive the threaded transmission rod 201 to rotate, and then the surface of the optical film is scraped and the bubbles inside the optical film are removed. Then, the optical film is pressed by the pressing roller 305. If the downward pressure is too large, the buffer spring 303 is compressed to reduce the pressure of the pressing roller 305 on the optical film. This is the working principle of the multi-layer laminating device for optical film.
