Technical Field

[0001] The utility model belongs to the technical field of film processing, and in particular relates to an ITO film winding device. Background Art

[0002] In the production of modern electronic products, transparent conductive film (Indium Tin Oxide, ITO) is widely used in display screens, touch screens and various optoelectronic devices due to its excellent transparency and conductivity. With the rapid development of electronic technology, the quality requirements for ITO films are getting higher and higher, especially in terms of film flatness and damage-free. Therefore, how to effectively and efficiently roll up ITO films to ensure their quality has become a technical problem that needs to be solved in the industry.

[0003] Existing ITO film winding equipment mostly adopts a simple mechanical winding method, which makes it difficult to avoid wrinkles or damage to the film during the winding process, especially when the film changes direction through multiple rollers. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an ITO film winding device, which can effectively prevent the ITO film from generating wrinkles during the winding process.

[0013] Furthermore, a motor frame is provided at the bottom of one end of the side plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting a smoothing mechanism in the winding device, which includes an adjustable first cylinder and a third roller with a threaded strip, the flatness of the ITO film before winding is effectively guaranteed. This design makes full use of the mirror setting of the threaded strip, which not only avoids the wrinkling of the film during the winding process, but also evenly disperses the film tension, significantly improving the flatness and winding quality of the film.

[0030] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0031] See also Figure 1-5, an ITO film winding device, including a frame 1, the frame 1 is composed of beams 11, the beams 11 are distributed in a triangular shape, and provide a stable support structure to ensure the stability and accuracy of the equipment during the winding process; and the two ends of the beams 11 are connected to side panels 12, and one end of the side panel 12 is provided with a winding mechanism 3 for effectively winding the ITO film to ensure the neatness and flatness of the film; and the other end of the side panel 12 is provided with a smoothing mechanism 2, and the smoothing mechanism 2 is responsible for performing preliminary flattening treatment on the ITO film to avoid wrinkles or damage to the film before winding, thereby improving the quality of the final product. The smoothing mechanism 2 includes a support platform 21, which is connected to the inner wall of the side plate 12 to provide stable support for the slide 22; and the slide 22 is slidably connected to the support platform 21, and the slide 22 is connected to a cross bar 23, and the first cylinder 25 is rotatably connected above the two ends of the cross bar 23, and the tail end of the first cylinder 25 is connected to the side of the side plate 12; the position of the cross bar 23 is controlled by the telescopic control of the first cylinder 25, and then the contact between the third roller 24 and the film is adjusted to ensure the flatness of the film. The side of the cross bar 23 is rotatably connected to the third roller 24, and the third roller 24 is mirror-set with a thread bar 241, and a fourth roller 26 is set on one side of the cross bar 23; the design of the thread bar 241 is conducive to dispersing the tension of the film during the winding process, and avoiding damage to the film due to concentrated force.

[0032] See also Figure 5 The inner side of the side plate 12 is rotatably connected with a first roller 13 and a second roller 14; the first roller 13 and the second roller 14 constitute the initial stage of film guiding, ensuring that the ITO film can smoothly enter the smoothing mechanism 2 and pass through the winding mechanism 3 according to a predetermined path. These two rollers are crucial to maintaining film tension and preventing film deviation.

[0033] See also Figure 5 The winding mechanism 3 includes a winding shaft 31 and a motor 35. A belt 351 is sleeved on the output end of the motor 35 and one end of the winding shaft 31. The motor 35 drives the winding shaft 31 to rotate through the belt 351. The belt transmission system can transmit power smoothly while reducing vibration and noise during movement, thereby ensuring the continuity and stability of the winding process.

[0034] See also Figure 5 A clamping frame 32 is provided on one side of the winding shaft 31, and the clamping frame 32 is rotatably connected to the inner side of one end of the side plate 12, and the side of the clamping frame 32 is rotatably connected to the second cylinder 33, the tail end of the second cylinder 33 is connected to the inner wall of the side plate 12, and the top of the clamping frame 32 is rotatably connected to the clamping shaft 34; this setting is used to adjust the pressure between the winding shaft 31 and the ITO film, and the position of the clamping frame 32 is controlled by the second cylinder 33, so as to ensure the consistency of the flatness and tension of the film during the winding process, and prevent the film from wrinkling or deformation during the winding process.

[0035] See also Figure 2-4 The top of the support platform 21 is fixedly connected with a track 211, and the slide 22 is installed on the track 211; the track 211 provides a precise linear guide for the slide 22, ensuring that the slide 22 can move smoothly along the predetermined path. This design not only enhances the stability and accuracy of the smoothing mechanism 2, but also provides a guarantee for the precise position adjustment of the cross bar 23 and the third roller 24, thereby further improving the flatness of the film during winding and reducing the possibility of film damage.

[0036] See also Figure 1 A motor frame 121 is disposed at the bottom of one end of the side plate 12. The motor frame 121 provides a stable installation platform for the motor 35, ensuring the stability of the motor 35 during long-term operation, thereby ensuring the continuous and stable operation of the winding mechanism 3. In addition, the design of the motor frame 121 also facilitates the maintenance and replacement of the motor 35, thereby improving the maintainability and service life of the entire device.

[0037] The working principle of the utility model is:

[0038] When in use, the ITO film to be rolled up needs to be passed over the first roller 13 in sequence, and passed between the third roller 24 and the fourth roller 26, and then the film is passed over the second roller 14 and wound around the roller on the winding shaft 31;

[0039] The motor 35 and the belt 351 cooperate to drive the winding shaft 31 to rotate synchronously, and the film is wound on the winding drum on the winding shaft 31 through the rotation of the winding shaft 31;

[0040] During the winding process, the first cylinder 25 is used to adjust the cross bar 23 to move closer to the fourth roller 26. When the third roller 24 contacts the film between the fourth roller 26 and the third roller 24, the third roller 24 rotates synchronously with the conveyance of the film. During the rotation of the third roller 24, the threaded strips 241 mirrored on the third roller 24 stretch the conveyed film toward both ends of the third roller 24, thereby avoiding wrinkles in the film during the winding process.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
