Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding device technology, specifically a winding device for thin film coating. Background Technology
[0002] Magnetron sputtering, electroplating, and vacuum evaporation are common methods for preparing high-quality thin films on material surfaces. They have wide applications in numerous fields such as electronics, optics, and decoration. For example, thin film deposition techniques can be used to prepare composite current collectors for lithium-ion batteries, forming a structure of a conductive layer-polymer layer-conductive layer. After the thin film deposition process is complete, the deposited film needs to be wound up.
[0003] In existing film winding devices, due to the diverse specifications and widths of films, the limiting structure of traditional winding devices is often difficult to adjust flexibly and cannot accurately control the limiting distance according to the winding requirements of films of different widths. As a result, the film is prone to deviating from the correct position and shifting during the winding process. Moreover, the existing limiting structure lacks effective fixing measures after adjustment. During the winding process, the limiting components are prone to movement due to equipment vibration or changes in film tension, further compromising the stability of film winding. At the same time, during the film limiting transmission process, due to external environmental interference, the film is prone to vertical shaking, resulting in unstable film limiting transmission and affecting winding efficiency. Therefore, this utility model provides a film coating winding device. Utility Model Content

[0018] Beneficial effects
[0019] This invention provides a winding device for thin film coating. Compared with the prior art, it has at least the following advantages:
[0020] Firstly, this invention, through the cooperation of the second screw and the U-shaped bracket, allows for flexible adjustment of the opening and closing distance of the limiting bracket to adapt to the winding requirements of films of different widths, ensuring that the film maintains the correct position during winding. Then, the third electric push rod is activated, and the telescopic end of the third electric push rod drives the clamping ring to move towards the positioning rod. The two sets of clamping rings clamp the positioning rod, thereby fixing the U-shaped bracket and the limiting bracket and preventing the limiting bracket from moving during winding, ensuring the stability of winding. During film transmission, the limiting plate provides a stable track, reducing the up-and-down shaking of the film caused by external interference, ensuring the smoothness of film transmission.

[0021] Secondly, this utility model uses a first electric push rod to lift and lower the top plate, which can flexibly adjust the position of the roller support according to the thickness of the film and the winding requirements to ensure effective pressing of the film. The combined use of shock-absorbing springs and damping rods absorbs the impact force when the film surface is uneven or the winding tension fluctuates, preventing the roller support from directly and rigidly contacting the film.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-6 This utility model provides a technical solution: a thin film coating winding device, including a support frame 1, with a winding roller 2 at one end of the support frame 1, the winding roller 2 being used to wind up the coated film. The support frame 1 is provided with an auxiliary winding mechanism for assisting in the winding of the thin film coating, the auxiliary winding mechanism including:
[0031] A pressing assembly is used to press the film wound on the take-up roller 2 to remove gas from the roll during film winding. The pressing assembly includes a horizontal plate 201 fixed to the inner wall of the support frame 1. A push plate 203 connected to the upper end of the horizontal plate 201 via a lifting assembly is provided. A roller pressing bracket 206 connected to the upper end of the push plate 203 via a shock absorption assembly is provided. The roller pressing bracket 206 is located below the take-up roller 2. The roller pressing bracket 206 is used to press the film on the take-up roller 2 and includes a rotating roller for contacting the film.
[0032] The limiting assembly includes mounting plates 5 fixed to the side walls of a support frame 1. Two positioning rods 501 are fixed to the side walls of the mounting plates 5. A limiting bracket 601, movably connected to the outer wall of each positioning rod 501 via a movable assembly, is provided. Movable rollers 602 are evenly distributed on the inner wall of the limiting bracket 601. At least two limiting plates 603 are provided inside the limiting bracket 601. The two limiting plates 603 are located on the upper and lower sides of the film, forming a space for the film to pass through. The limiting plates 603 are used to limit the film's vertical movement when it vibrates due to external interference, reducing fluctuations. The movable rollers 602 are used to contact the film edge and are rollable to reduce friction on the film edge. The movable limiting bracket 601 allows adjustment of the positions of the limiting plates 603 and the movable rollers 602, making it suitable for films of different widths.
[0033] The roll forming assembly includes a vertical rod 3 disposed at the other end of a support frame 1. A first pressure shaft 301 is rotatably connected inside the vertical rod 3. An L-shaped plate 302 is fixed to the side wall of the vertical rod 3. A slider 304 is slidably connected to the inner wall of the L-shaped plate 302. A movable block 307 connected to the lower end of the slider 304 via an elastic component is disposed. A second pressure shaft 308 is rotatably connected to the inner wall of the movable block 307. The first pressure shaft 301 and the second pressure shaft 308 are arranged opposite to each other, forming a channel between the first pressure shaft 301 and the second pressure shaft 308 for the film to pass through. The first pressure shaft 301 and the second pressure shaft 308 can cooperate with each other to press the film passing between the first pressure shaft 301 and the second pressure shaft 308, thereby stabilizing the film. At the same time, it can press down some protrusions on the surface of the film, thereby improving the flatness of the film surface. For example, the surface of a composite aluminum current collector prepared by vacuum evaporation will have bumps due to splashed aluminum droplets, and the composite copper current collector prepared by electroplating will have undulating structures due to uneven current. The roll pressing assembly can press the bumps and undulating structures of the metal material downward into the polymer layers of the composite copper current collector or the composite aluminum current collector.
[0034] The winding quality of the winding device is improved by the cooperation of the pressing component, the limiting component, and the roller pressing component.
[0035] In a preferred embodiment, the lifting assembly includes a pair of first electric push rods 202 fixed to the upper surface of the horizontal plate 201, and a push plate 203 fixedly connected to the telescopic end of the first electric push rods 202. When the first electric push rods 202 are activated, the telescopic end of the first electric push rods 202 drives the push plate 203 to move up and down.
[0036] The damping assembly includes a damping spring 204 fixed to the upper end face of the push plate 203, a roller support 206 located at the upper end of the damping spring 204, and a damping rod 205 provided in the inner ring of the damping spring 204. The damping rod 205 is located between the push plate 203 and the roller support 206 and is fixedly connected to each other.
[0037] During the lifting and lowering process, the push plate 203 drives the roller support 206 to move through the shock-absorbing spring 204 and the damping rod 205. The shock-absorbing spring 204 and the damping rod 205 play a buffering and shock-absorbing role, so that the roller support 206 can smoothly press the film, prevent the take-up roller 2 from generating air bubbles when winding the film, and ensure effective pressing of the film.
[0038] The first electric push rod 202 is used to raise and lower the push plate 203. The position of the roller support 206 can be flexibly adjusted according to the thickness of the film and the winding requirements to ensure effective pressing of the film. The shock-absorbing spring 204 and the damping rod 205 work together to absorb the impact force when the film surface is uneven or the winding tension fluctuates, thus preventing the roller support 206 from directly and rigidly contacting the film.
[0039] In a preferred embodiment, the movable component includes a second screw 503 rotatably connected to the side wall of the mounting plate 5. The second screw 503 is located between two positioning rods 501. A U-shaped bracket 502 is slidably connected to the outer wall of the positioning rod 501. The U-shaped bracket 502 is threadedly connected to the second screw 503. A guide rod 6 is fixed to the upper end of the U-shaped bracket 502. A limiting bracket 601 is fixedly connected to one end of the guide rod 6. Two sets of limiting brackets 601 are provided, distributed on both sides of the support frame 1. A locking component for fixing is provided on the outer side of the positioning rod 501. The locking component includes... A third electric push rod 504 is provided on the side wall of the U-shaped bracket 502 near the positioning rod 501. The telescopic end of the third electric push rod 504 is fixedly connected to a clamping ring 505, and the clamping ring 505 is configured in two sets. The two sets of clamping rings 505 are located on the upper and lower sides of the positioning rod 501. When the second screw 503 is rotated, since the U-shaped bracket 502 is threadedly connected to the second screw 503 and the U-shaped bracket 502 slides on the outer wall of the positioning rod 501, the rotation of the second screw 503 causes the U-shaped bracket 502 to slide on the positioning rod 501, thereby adjusting the lateral position of the limiting bracket 601 to adapt to films of different widths.
[0040] Furthermore, through the cooperation of the second screw 503 and the U-shaped bracket 502, the opening and closing distance of the limiting bracket 601 can be flexibly adjusted to adapt to the winding requirements of films of different widths, ensuring that the film maintains the correct position during the winding process.
[0041] Once the appropriate width is achieved, the third electric push rod 504 is activated. The telescopic end of the third electric push rod 504 drives the clamping ring 505 to move towards the positioning rod 501. The two sets of clamping rings 505 clamp the positioning rod 501, thereby fixing the U-shaped bracket 502 and the limiting bracket 601, preventing the limiting bracket 601 from moving during the winding process, and ensuring the stability of the winding.
[0042] In a preferred embodiment, two limiting plates 603 are connected to a limiting bracket 601 via an opening and closing assembly. The opening and closing assembly includes a bidirectional screw 605 disposed on the side wall of the limiting bracket 601 away from the movable roller shaft 602. A groove is formed on the side wall of the limiting bracket 601, and an adjusting block 604 is slidably connected inside the groove. One end of the adjusting block 604 is threadedly connected to the bidirectional screw 605, and the adjusting block 604 extends into the limiting bracket 601 and is fixedly connected to the limiting plate 603. Two sets of limiting plates 603 are configured, each set having evenly spaced through holes through which the movable roller shaft 602 passes. Each set of limiting plates 603 is connected to an adjusting block 604, and the two adjusting blocks 604 are positioned at different thread directions on the bidirectional screw. This configuration allows the two sets of limiting plates 603 to move towards or away from each other during the rotation of the bidirectional screw 605.
[0043] During operation, rotating the bidirectional screw 605 causes the adjusting block 604 to move. Since the adjusting block 604 is threadedly connected to the bidirectional screw 605 and slides within the groove on the side wall of the limiting bracket 601, the rotation of the bidirectional screw 605 drives the adjusting block 604 to move. The adjusting block 604 then moves the limiting plate 603 within the limiting bracket 601, thereby adjusting the distance between the two sets of limiting plates 603. This adjustment is made according to the thickness of the film being wound, preventing vertical shaking during film winding. The film is always within the reasonable space defined by the limiting plates 603 during winding, avoiding insufficient constraint on the film in the width direction due to excessive spacing between the limiting plates 603, or excessive compression of the film due to insufficient spacing, which would affect its flatness.
[0044] During film transport, the limiting plate 603 provides a stable track, guiding the film along the correct path and reducing the up-and-down shaking caused by external interference, ensuring the smoothness of film transport. By precisely adjusting the spacing of the limiting plates 603 to avoid shaking, the film can maintain uniform tension and flatness during winding, thus ensuring a neat appearance of the wound film roll.
[0045] In a preferred embodiment, the upper end of the L-shaped plate 302 is threadedly connected to a first screw 303, which is rotatably connected to the upper end of the slider 304. The slider 304 has a U-shaped groove, and the groove of the slider 304 is slidably connected to the L-shaped plate 302. The elastic component includes a pair of compression springs 305 disposed at the lower end of the slider 304, a movable block 307 located at the lower end of the compression springs 305, and a slide rod 306 disposed on the inner ring of the compression springs 305. The upper end of the slide rod 306 is fixedly connected to the slider 304, and the lower end of the slide rod 306 is slidably connected to the movable block 307.
[0046] When the first screw 303 is rotated, it is rotatably connected to the upper end of the slider 304, and the slider 304 slides on the inner wall of the L-shaped plate 302. Therefore, the rotation of the first screw 303 drives the slider 304 to slide up and down on the inner wall of the L-shaped plate 302. The lower end of the compression spring 305 is fixedly connected to the movable block 307. Thus, the slider 304 drives the movable block 307 to move up and down through the compression spring 305 and the slide rod 306. The movable block 307 drives the second pressure shaft 308 to move, adjusting the distance between the second pressure shaft 308 and the first pressure shaft 301. During the film winding process, the compression spring 305 plays an elastic buffering role, enabling the second pressure shaft 308 to automatically adjust the pressure according to the thickness change of the film and maintain stable pressing of the film.
[0047] Furthermore, through the cooperation of the first screw 303 and the slider 304, the distance between the second pressure shaft 308 and the first pressure shaft 301 can be flexibly adjusted to adapt to the pressing requirements of films of different thicknesses, ensuring that the film is tightly adhered during the winding process. Then, the setting of the compression spring 305 and the slide bar 306 can automatically adjust the pressure of the second pressure shaft 308 when the film thickness changes, avoiding damage to the film due to excessive pressure or failure to stabilize the film due to insufficient pressure.
[0048] In a preferred embodiment, a second electric push rod 4 is provided on one side of the vertical rod 3 at the upper end of the support frame 1. A first adjusting roller 401 is provided at the upper end of the second electric push rod 4, and second adjusting rollers 402 are respectively provided on both sides of the first adjusting roller 401. When the second electric push rod 4 is activated, the telescopic end of the second electric push rod 4 drives the first adjusting roller 401 to move up and down, adjusting the height of the first adjusting roller 401. Then, the first adjusting roller 401 and the second adjusting rollers 402 on both sides work together to adjust the transmission path and tension of the film. The coordinated use of the first adjusting roller 401 and the second adjusting roller 402 can adjust the tension of the film according to the characteristics of the film and the winding speed, so that the film maintains appropriate tension during the winding process, avoids the film from becoming loose or broken, and improves the winding effect.
[0049] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0050] When the film coating winding device is working, in the pressing assembly, the first electric push rod 202 is activated, and its telescopic end drives the top push plate 203 to rise and fall. The top push plate 203 drives the roller pressing bracket 206 to move through the shock-absorbing spring 204 and the damping support rod 205. The position of the roller pressing bracket 206 can be flexibly adjusted according to the film thickness and winding requirements to effectively press the film. At the same time, the shock-absorbing spring 204 and the damping support rod 205 can absorb the impact force and prevent the roller pressing bracket 206 from rigidly contacting the film.
[0051] In the limiting assembly, rotating the second screw 503 causes the U-shaped bracket 502, which is threadedly connected to the second screw 503 and slides on the outer wall of the positioning rod 501, to slide. The lateral position of the limiting bracket 601 is adjusted to accommodate films of different widths. The third electric push rod 504 is activated, and its telescopic end drives the clamping ring 505 to clamp the positioning rod 501, fixing the U-shaped bracket 502 and the limiting bracket 601. Rotating the bidirectional screw 605 causes the adjusting block 604, which is threadedly connected to the bidirectional screw 605 and slides in the slide groove on the side wall of the limiting bracket 601, to move. The adjusting block 604 causes the limiting plate 603 to move inside the limiting bracket 601. The distance between the two sets of limiting plates 603 is adjusted according to the film thickness to avoid the film shaking up and down during winding. The contact between the limiting bracket 601 and the movable roller shaft 602 can reduce the friction during limiting.
[0052] In the roll forming assembly, rotating the first screw 303 causes the slider 304, which is rotatably connected to the first screw 303 and slides on the inner wall of the L-shaped plate 302, to slide up and down. The slider 304 drives the movable block 307 to move up and down through the compression spring 305 and the slide rod 306. The movable block 307 drives the second pressure shaft 308 to move, adjusting the distance between the second pressure shaft 308 and the first pressure shaft 301. During the film winding process, the compression spring 305 plays an elastic buffering role, allowing the second pressure shaft 308 to automatically adjust the pressure according to the change in film thickness. In addition, the second electric push rod 4 is activated, and its telescopic end drives the first adjusting roller shaft 401 to move up and down, adjusting the height of the first adjusting roller shaft 401. The first adjusting roller shaft 401 and the second adjusting roller shafts 402 on both sides work together to adjust the film's transmission path and tension, so that the film maintains appropriate tension during the winding process and avoids slackness or breakage.
