Description

Technical Field

[0001] The present application relates to the field of optical elements, and in particular to a device and method for manufacturing an optical film. Background Art

[0002] Optical film is a thin film that regulates light and is a type of optical element. An optical film is a thin and uniform dielectric film layer attached to the surface of an optical device through different coating technologies. During the propagation of light, it can achieve functions such as allowing all light within a certain or multiple wavelength ranges to pass through, reflect all light, and separate polarization of light through the reflection, transmission, refraction, and polarization characteristics of the multi-layer dielectric film layer.

[0003] In the research work of manufacturing optical films, the pull-up coater is a commonly used instrument for manufacturing optical films. The pull-up coater forms a thin film by immersing the substrate vertically into the coating solution, then vertically pulling the substrate up from the solution at a low speed, and allowing the attached liquid film to gel in the air. This method can accurately control the thickness and quality of the film by controlling parameters such as pulling speed, pulling height, immersion time, multiple multilayer coatings, and coating interval time.

[0004] In the process of transforming the wet gel film on the surface of the substrate into a dry gel film, drying and high-temperature heat treatment are required. Therefore, a heating instrument is often installed on one side of the lifting coater. After the substrate is lifted, the linear module in the lifting coater is used to extend the substrate through the window into the heating instrument on one side. The final formation of the optical film requires multiple layers of coating. The reciprocating movement between the heating instrument and the coating instrument will inevitably prolong the coating time, and the long-term transfer of the thin film on the surface of the substrate during the heating instrument will affect the uniformity of the coating.

DETAILED DESCRIPTION

[0015] The embodiment of the present application discloses a manufacturing device and method for an optical film. Through the various mechanisms and components in the manufacturing device, after the substrate is coated in the solution and lifted, it can quickly enter the arc-shaped heating box 6 on one side, shortening the movement time and reducing the waiting time for heating, and the substrate can be flipped in the arc-shaped heating box 6. During the flipping process, the heat flow can flow around the substrate, and the substrate located in the middle of the clamp 2 can also contact the heat flow like the outer substrate, which is useful for ensuring the uniformity of heating of each substrate, so that the quality of the optical film on each substrate tends to a standard, and solves the technical problem of the optical film manufacturing device in the prior art that the coating time is long during multiple multi-layer coating processes, which affects the uniformity of the coating, and shortens the coating time in the optical film manufacturing process, and the film can be quickly dried and heated after being lifted, ensuring the uniformity of the coating.

[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] Embodiment 1: A manufacturing device for an optical film, referring to Figure 1 and Figure 2The manufacturing device includes a chassis 1, a fixture 2, a linear telescopic electric cylinder 3, a swing frame 4, a swing driving mechanism 5, an arc-shaped heating box 6, a support frame 7, and a split mechanism 8. A material table 100 is arranged inside the chassis 1. The material table 100 is horizontally fixed in the middle of the bottom surface of the chassis. The material table 100 is used to place a beaker 200. The beaker 200 is used to hold a coating solution. A control box 300 is integrated at the bottom of the chassis 1, and a control panel is located on the outer surface of the control box 300. The swing frame 4 is located directly above the material table 100, the linear telescopic electric cylinder 3 is installed on the swing frame 4, the clamp 2 is fixed to the end of the telescopic rod 31 of the linear telescopic electric cylinder 3, the clamp 2 is used to clamp multiple substrates, the support frame 7 is fixed to the inner wall of the chassis 1, the support frame 7 is located on one side of the swing frame 4, the swing frame 4 is rotatably set on the support frame 7, the swing driving mechanism 5 is installed on the support frame 7, and the arc-shaped heating box 6 is located on the other side of the swing frame 4. Therefore, the swing frame 4 is located between the arc-shaped heating box 6 and the support frame 7, and the split mechanism 8 is installed at the lower end of the arc-shaped heating box 6.

[0018] Reference Figure 2 and Figure 3 The swing frame 4 includes a U-shaped plate 41 and a lower extension plate 42 which are fixedly connected to each other. The U-shaped plate 41 is in a U shape. The lower extension plate 42 is fixedly connected to the end of one end of the horizontal bottom plate in the U-shaped plate 41. The extension direction of the lower extension plate 42 is opposite to the notch direction of the U-shaped plate 41. The cylinder body of the linear telescopic electric cylinder 3 is rotatably arranged in the middle of the horizontal bottom plate in the U-shaped plate 41, and the linear telescopic electric cylinder 3 is located on the outside of the U-shaped plate 41. The axis direction of the telescopic rod 31 in the linear telescopic electric cylinder 3 is consistent with the length direction of the lower extension plate 42. The axis of the rotating shaft of the linear telescopic electric cylinder 3 is colinear with the axis of the telescopic rod 31 in the linear telescopic electric cylinder 3. One side of the support frame 7 extends into the U-shaped plate 41 of the swing frame 4. The rotating shaft of the swing frame 4 is fixed between the vertical plates on both sides of the U-shaped plate 41, and the rotating shaft is rotatably arranged on the support frame 7. The rotating shaft is arranged horizontally and perpendicular to the door of the chassis 1 in the closed state. Therefore, the swinging surface of the telescopic rod 31 in the linear telescopic electric cylinder 3 is parallel to the door of the chassis 1 in the closed state, and the arc-shaped heating box 6 is located on the swinging surface of the telescopic rod 31 in the linear telescopic electric cylinder 3, and the center of the arc of the arc-shaped heating box 6 is located on the rotating shaft of the swing frame 4.

[0019] Continue to refer to Figure 3 and Figure 4The swing mechanism 5 includes a fixed bevel gear 51, a rotating bevel gear 52, a swing plate 53, a driving motor 54 and a swing rod 55. The fixed bevel gear 51 is located in the U-shaped plate 41 of the swing frame 4 and is fixed on the support frame 7, and the axis of the fixed bevel gear 51 is horizontal and perpendicular to the swing surface of the telescopic rod 31 in the linear telescopic electric cylinder 3. The middle of the fixed bevel gear 51 is hollow, and the rotating shaft of the swing frame 4 passes through the center of the fixed bevel gear 51, so that the fixed bevel gear 51 is in a fixed state, and the fixed bevel gear 51 will not affect the rotation of the rotating shaft in the swing frame 4. The rotating bevel gear 52 is located on the U-shaped plate 41, and the rotating bevel gear 52 is rotatably arranged on the horizontal bottom plate of the U-shaped plate 41 and meshes with the fixed bevel gear 51. The rotating axis of the rotating bevel gear 52 is coaxially connected with the rotating axis of the linear telescopic electric cylinder on the U-shaped plate 41, so that the rotation of the rotating bevel gear 52 can drive the swing of the linear telescopic electric cylinder 3. The swing plate 53 is rotatably arranged on the support frame 7 and is located on the side of the linear telescopic electric cylinder 3 away from the arc-shaped heating box 6. The swing plate 53 is parallel to the swing surface of the telescopic rod 31 in the linear telescopic electric cylinder 3. The driving motor 1 54 is installed on the support frame 7 and is used to drive the swing plate 53 to rotate. One end of the swing rod 55 is hinged to the edge of the swing plate 53, and the other end is hinged to the end of the lower extension plate 42 in the swing frame 4 away from the end of the U-shaped plate 41.

[0020] When the driving motor 54 is started, it will drive the swing plate 53 to rotate, and the rotation of the swing plate 53 will drive the swing rod 55 to move, so that the swing rod 55 will push the swing frame 4 to swing, and the rotating bevel gear 52 will swing with the swing frame 4. Since the fixed bevel gear plate 51 is fixed, the rotating bevel gear 52 rotates while circling around the fixed bevel gear plate 51, thereby driving the linear telescopic electric cylinder 3 to rotate, thereby causing the linear telescopic electric cylinder 3 to rotate while swinging.

[0021] Reference Figure 2 and Figure 5As shown, the bottom end of the arc-shaped heating box 6 is open, and the top end is closed. The concave arc surface of the arc-shaped heating box 6 is provided with a path groove 601 through which the telescopic rod 31 in the linear telescopic electric cylinder 3 passes when it swings. Therefore, the telescopic rod 31 in the linear telescopic electric cylinder 3 can move in the path groove 601 when it swings without causing interference. The width of the arc-shaped heating box 6 is greater than the maximum diameter of the fixture 2 when it rotates, so that the fixture 2 can move in the arc-shaped heating box 6 without hindrance. A plurality of heating wires 61 are installed inside the arc-shaped heating box 6. The heating wires 61 are U-shaped in the arc-shaped heating box 6, and the opening faces the path groove 601. 1. A power harness 603 is connected to the top of the arc-shaped heating box 6, and the power harness 603 is used to energize the heating wire 61. Heat-resistant rubber sheets 602 are fixedly connected to both sides of the slot of the path slot 601. The heat-resistant rubber sheets 602 on both sides are staggered. The heat-resistant rubber sheets 602 can be used to prevent the heat from flowing out of the arc-shaped heating box 6. The heat-resistant rubber sheets 602 are made of soft material, so that the telescopic rod 31 in the linear telescopic electric cylinder 3 can push aside the heat-resistant rubber sheets 602 and move in the path slot 601. The heat-resistant rubber sheets 602 that are not pushed aside by the telescopic rod 31 in the telescopic electric cylinder 3 still keep the function of preventing the heat from flowing out.

[0022] Reference Figure 5 and Figure 6 , an insulating door panel 62 is provided at the opening of the arc-shaped heating box 6. The insulating door panel 62 is provided with two pieces and is arranged to open in an opposite direction. The opening direction is consistent with the width direction of the arc-shaped heating box 6. The insulating door panel 62 can prevent the heat in the inner cavity of the arc-shaped heating box 6 from flowing out of the port. The arc-shaped heating box 6 is provided with an opening mechanism 8 for opening and closing the insulating door panels 62 on both sides. The opening mechanism 8 includes a slide rail 81, a slider 82, a rack 83, a spur gear 84, and a second drive motor 85. The slide rail 81 is horizontally arranged. The length direction of the slide rail 81 is consistent with the opening and closing direction of the two insulating door panels 62. The slide rail 81 is fixed to the bottom of the opening end of the arc-shaped heating box 6 through a connecting block 801; there are two sliders 82, and the two sliders 82 are respectively fixed to the insulating door panels 62 on both sides. The two sliders 82 are both slidably connected to the slide rail 81; there are two racks 83, and both are located on the slide rail 81. 1, the length direction of the rack 83 is consistent with the length direction of the slide rail 81, one rack 83 is fixedly connected to the heat-insulating door panel 62 on one side, and the other rack 83 is fixedly connected to the heat-insulating door panel 62 on the other side, and the teeth of the two racks 83 are arranged face to face; the spur gear 84 is meshed between the two racks 83, and the spur gear 84 is located just below the closed part of the heat-insulating door panels 62 on both sides; the driving motor 85 is installed at the bottom of the arc-shaped heating box 6, and the driving motor drives the spur gear 84 to rotate.

[0023] The second drive motor 85 is started to drive the spur gear 84 to rotate forward and reversely. The forward and reverse rotation of the spur gear 84 will drive the two racks 83 to overlap or move away from each other, thereby closing or opening the heat insulation door panels 62 on both sides. Therefore, when the swing drive mechanism 5 is running, before the linear telescopic electric cylinder swings to one side of the arc-shaped heating box 6, the second drive motor 85 is started, and the opening mechanism 8 is used to open the heat insulation door panels 62 on both sides, so that the clamp 2 with the substrate clamped enters the arc-shaped heating box 6.

[0024] The functional principle of the first embodiment of the present application can be explained through the following operation mode: In the research work of manufacturing optical films, the prepared coating solution can be poured into the beaker 200, and then the beaker 200 is placed on the material table 100, and the substrate is clamped on the clamp 2. The clamp 2 can have the function of clamping multiple substrates. After that, the linear telescopic electric cylinder 3 is started, and the telescopic rod 31 in the linear telescopic electric cylinder 3 is extended, and the substrate is vertically immersed in the coating solution for immersion. Then the telescopic rod 31 is retracted, and the substrate is vertically pulled up from the solution at a low speed. After being pulled to a preset position, the insulating door plate 62 of the arc-shaped heating box 6 is opened by the split mechanism 8, and then the driving swing mechanism 5 is started. The driving motor 54 in the driving swing mechanism 5 will drive the swing plate 53 to rotate, and then under the action of the swing rod 55, the rotating bevel gear 52 rotates while circling around the fixed bevel gear plate 51, so that the linear telescopic electric cylinder 3 rotates while swinging into the arc-shaped heating box 6.

[0025] Therefore, after the substrate is coated in the solution and pulled up, it can quickly enter the arc-shaped heating box 6 on one side, shortening the movement time and reducing the waiting time for heating, and the substrate can be flipped in the arc-shaped heating box 6. During the flipping process, the heat flow can flow around the substrate, and the substrate located in the middle of the clamp 2 can also contact the heat flow like the outer substrate, which is beneficial to ensure the uniformity of heating of each substrate and make the quality of the optical film on each substrate approach a standard, solving the technical problem of the optical film manufacturing device in the prior art that the coating time is long during multiple multi-layer coating processes, which affects the uniformity of the coating, and shortens the coating time in the optical film manufacturing process, and the thin film can be quickly dried and heated after being pulled, thereby ensuring the uniformity of the coating.

[0026] Embodiment 2: A method for manufacturing an optical film comprises the following steps: S1, coating solution preparation.

[0027] In a specific implementation, the prepared coating solution is poured into the beaker 200 , and the beaker 200 is placed on the material table 100 of the chassis 1 .

[0028] S2, substrate clamping.

[0029] In a specific implementation, the substrate is clamped on the clamp 2, and the clamp 2 can have the function of clamping multiple substrates.

[0030] S3, substrate dipping.

[0031] In a specific implementation, a button on the control box 300 is operated to start the linear telescopic electric cylinder 3, so that the substrate on the fixture 2 enters the beaker 200 for immersion.

[0032] S4, substrate lifting.

[0033] In a specific implementation, after the substrate is immersed in the coating solution for a preset time, the linear telescopic electric cylinder 3 is used to pull the substrate at a low speed.

[0034] S5, membrane heating.

[0035] In a specific implementation, after being pulled to a preset position, the swing driving mechanism 5 is started, so that the clamp 2 with the substrate enters the arc-shaped heating box 6 for heating.

[0036] S6, multiple coating heating.

[0037] In a specific implementation, the final formation of the optical film requires multiple layers of coating, repeated immersion, pulling and heating of the substrate to complete the manufacture of the optical film.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.

[0039] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto.
