[0030] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 6 As shown, this utility model embodiment provides an automatic winding device for optical films, including a frame 1, a film winding roller 2, a winding motor 3, a telescopic rotating shaft mechanism 4, a swing frame 5, and a swing cylinder 6. The swing frame 5 has a U-shaped structure, and its two sides are rotatably connected to the frame 1 via rotating shafts 51. The swing cylinder 6 is located on the top of the frame 1, with its movable end facing downwards, and is connected to the swing frame 5. The swing cylinder 6 is used to drive the swing frame 5 to swing around the rotating shaft 51. The film winding roller 2 is mounted on the swing frame 5. After the optical film is wound up, the film winding roller 2, which is full of optical film, needs to be unloaded and replaced. At this time, by controlling the extension and retraction of the swing cylinder 6, the swing frame 5 is driven to rotate around the rotating shaft 51, thereby driving the film winding roller 2 to swing downwards to a height close to the ground, making it easier to place the film winding roller 2 stably on the ground for disassembly, avoiding manual lifting, and reducing the labor intensity of the optical film unloading operation.

[0034] The winding motor 3 is located on one side of the swing frame 5. The output shaft of the winding motor 3 is detachably connected to one end of the film winding roller 2 through the connecting disc assembly 7. The winding motor 3 is used to drive the film winding roller 2 to rotate, so as to achieve the winding of the optical film. The optical film is conveyed from the front-end process. When it needs to be wound onto the film winding roller 2, the winding motor 3 is started to drive the film winding roller 2 to rotate at a set speed through the connecting disc assembly 7, thereby achieving uniform winding of the optical film.

[0035] The telescopic rotating shaft mechanism 4 includes a telescopic cylinder 41, a telescopic arm 42, a sliding shaft 43, a bearing seat 44, and a first chuck 45. The bearing seat 44 is located at the other end of the swing frame 5. The sliding shaft 43 is slidably disposed within the bearing seat 44. The first chuck 45 is located at the end of the sliding shaft 43. The first chuck 45 is used to engage with or disengage from the film roll 2 as the sliding shaft 43 moves telescopically. The telescopic cylinder 41 is located at the side end of the swing frame 5, and its movable end is connected to the sliding shaft 43 through the telescopic arm 42. The telescopic cylinder 41 is used to drive the sliding shaft 43 to slide along the axial direction of the bearing seat 44. When installing the film roll 2, the operator first connects and fixes one end of the film roll 2 to the connecting plate assembly 7, and then controls the telescopic cylinder 41 to extend, so that the telescopic arm 42 pushes the sliding shaft 43 forward along the axis of the bearing seat 44, so that the first chuck 45 at the end of the sliding shaft 43 is inserted into the film roll 2, thereby supporting and clamping the non-drive end of the film roll 2, thus completing the loading operation of the film roll 2; when the film roll 2 needs to be disassembled after the winding operation is completed, the telescopic cylinder 41 is controlled to retract, so that the sliding shaft 43 moves in the opposite direction, and the first chuck 45 is then removed from the film roll 2, thereby completing the automatic release of the non-drive end of the film roll 2. This setting effectively reduces the efficiency of disassembly and replacement of the film roll 2.

[0036] like Figure 3 and Figure 4 As shown, the connecting disc assembly 7 further includes a second chuck 71 and a roller flange 72. The roller flange 72 is located on the side wall of the film roll 2. One end of the second chuck 71 is connected to the output shaft of the take-up motor 3, and the other end of the second chuck 71 is provided with a snap-fit ​​protrusion 711. The roller flange 72 is provided with a snap-fit ​​groove 721 that is adapted to snap-fit ​​the snap-fit ​​protrusion 711. During the installation of the film roll 2, the operator can push the film roll 2 into the take-up motor 3, so that the snap-fit ​​groove 721 on the roller flange 72 and the snap-fit ​​protrusion 711 on the second chuck 71 are aligned and snap-fitted, thereby improving the ease of disassembly and assembly of the film roll 2.

[0037] like Figure 5 and Figure 6 As shown, further, the film roll 2 is provided with a positioning groove 21 on the side wall near the first chuck 45. The positioning groove 21 is used to abut against the first chuck 45, thereby realizing the positioning and clamping of the non-drive end of the film roll 2.

[0038] like Figure 1 and Figure 2As shown, the swing frame 5 is further provided with swing arms 52 on both sides, and the swing arms 52 have a hollow cavity inside. The telescopic arm 42 is located in the hollow cavity, and the movable end of the telescopic cylinder 41 extends into the hollow cavity and is connected to the telescopic arm 42. This arrangement can avoid the telescopic arm 42 from being exposed and reduce the risk of mechanical interference caused by being stuck by foreign objects.

[0039] like Figure 1 As shown, the number of swing cylinders 6 is two sets.

[0040] like Figure 1 As shown, the film roll 2 is further designed with an I-shaped structure. Limiting baffles 22 are provided on both sides of the film roll 2. The middle of the film roll 2 is the winding area. With the blocking effect of the limiting baffles 22, the winding neatness of the optical film can be improved.

[0041] like Figure 1 As shown, the winding motor 3 is further a geared motor. The geared motor can convert the high-speed rotation of the winding motor 3 into a low-speed, high-torque output through the built-in reduction mechanism, so that the film roll 2 rotates slowly at a constant speed, thereby improving the winding stability of the optical film.

[0042] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
