Description

Technical Field

[0001] This utility model belongs to the field of dimming film processing technology, and specifically relates to a coating equipment for applying sealant to dimming film. Background Technology

[0002] A dimming film is an electronic light-controlling product that achieves dimming functionality by injecting a liquid crystal / polymer hybrid material between two transparent conductive films.

[0003] Currently, Chinese utility model patent CN214383304U discloses a coating and laminating device suitable for dynamic dimming films. In the current dimming film processing, a sealant needs to be coated onto the film to protect it. However, in existing dimming film coating processes, the sealant is dried and cured using a UV lamp. To ensure curing effectiveness, the UV lamp is usually positioned close to the top of the dimming film, resulting in limited top space on the worktable and making it inconvenient for workers to remove and place the film. Furthermore, because the ultraviolet light from the UV lamp is relatively diffuse, the sealant on the dimming film often appears partially cured, with some areas cured while others remain incomplete. Existing coating equipment cannot adjust the UV lamp's angle to concentrate the irradiation on the partially cured sealant, leading to low curing efficiency and making it impractical for real-world use. Utility Model Content

[0004] The purpose of this invention is to provide a coating device for applying dimming film sealant, which has the advantages of improving the curing efficiency of the sealant and facilitating the vertical adjustment of the UV irradiation lamp, thereby simplifying the operation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a coating device for applying dimming film sealant, comprising a base, a top cover bolted to the top of the base, a lifting frame slidably connected inside the top cover, a ring-shaped UV lamp bolted to the bottom of the lifting frame, synchronous pulleys rotatably connected to both sides of the top and bottom of the top cover, a synchronous belt cooperating with the lifting frame being drivenly connected to the surface of the synchronous pulleys, a drive motor mounted on one side outside the top cover, the output end of the drive motor being fixedly connected to the synchronous pulleys; a lampshade bolted to the bottom of the ring-shaped UV lamp, a light guide grid provided inside the lampshade, a rotating shaft rotatably connected to the lampshade being welded to both ends of the light guide grid, a protective shell bolted to one side outside the lampshade, a gear fixedly sleeved at one end of the rotating shaft near the protective shell, and a linear rack meshing with the gear being slidably connected inside the protective shell.

[0006] By employing the above technical solution, the ring-shaped UV lamp slides up and down on the top of the base, allowing it to descend closer to the dimming film for rapid curing of the sealant. Simultaneously, it can rise, ensuring sufficient space above the workbench for easy removal and repositioning of the dimming film, improving practicality. By rotating and tilting the light guide grille inside the lamp cover, the angle of the ultraviolet light emitted by the ring-shaped UV lamp can be adjusted, facilitating concentrated irradiation of the left and right sides of the dimming film. This reduces incomplete curing of the sealant and improves the quality of the sealant application on the dimming film.

[0007] The present invention is further configured such that: a workbench is bolted to the top of the base, and an applicator head is installed on one side of the top of the workbench.

[0008] By adopting the above technical solution, the dimming film can be automatically coated with adhesive, thereby improving the coating efficiency.

[0009] The present invention is further configured such that: a Y-axis electric slide is bolted to both sides of the top of the worktable; an X-axis electric slide is slidably connected to one end of the top of the Y-axis electric slide; a Z-axis electric slide is slidably connected to one end of the top of the X-axis electric slide; and the glue applicator is slidably connected to one side of the Z-axis electric slide.

[0010] The above technical solution facilitates the movement of the coating head to different positions, enabling the coating head to uniformly apply adhesive to the top of the dimming film.

[0011] The present invention is further configured such that: a glue storage tank for use with a glue applicator is bolted to one side of the top of the workbench, and a vacuum mesh plate is bolted to the inside of the workbench.

[0012] By adopting the above technical solution, the excess sealant can be leaked to the bottom using a vacuum mesh plate, thereby preventing excess sealant from accumulating on the worktable.

[0013] The present invention is further configured such that a reflector is adhered to the inner surface of the lampshade.

[0014] By employing the above technical solution, the ultraviolet rays emitted by the ring UV lamp are focused, thereby improving the drying and curing efficiency.

[0015] The present invention is further configured such that a control panel is bolted to one side of the base for use with the glue applicator, the drive motor, and the ring UV lamp.

[0016] The above technical solution facilitates centralized control of the equipment and improves operational convenience.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By sliding the ring-shaped UV lamp up and down on the top of the machine base, the lamp can be lowered to approach the dimming film for rapid curing of the sealant. It can also be raised to ensure sufficient space above the workbench, making it easy for workers to remove and reposition the dimming film, thus improving practicality.

[0019] 2. By rotating and tilting the light guide grille inside the lampshade, the angle of the ultraviolet light emitted by the ring UV lamp can be adjusted, facilitating concentrated irradiation of the left and right sides of the dimming film. This reduces the occurrence of incomplete curing of the sealant and improves the quality of the sealant application on the dimming film. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2A coating device for applying sealant to a dimming film includes a base 1, a top cover 2 bolted to the top of the base 1, a lifting frame 7 slidably connected inside the top cover 2, and a ring-shaped UV lamp 8 bolted to the bottom of the lifting frame 7. Synchronous pulleys 4 are rotatably connected to both the top and bottom sides of the top cover 2, and a synchronous belt 5, which works in conjunction with the lifting frame 7, is driven by the surface of the synchronous pulleys 4. A drive motor 6 is installed on one side of the outside of the top cover 2, and the output end of the drive motor 6 is fixedly connected to the synchronous pulleys 4. By driving the ring-shaped UV lamp 8 to slide up and down on the top of the base 1, the ring-shaped UV lamp 8 can be lowered to approach the dimming film for rapid curing of the sealant. It can also be raised to ensure sufficient space above the worktable, facilitating the removal and repositioning of the dimming film by the operator, thus improving practicality.

[0029] refer to Figure 1 , Figure 3 A worktable 15 is bolted to the top of the base 1, and an adhesive applicator 16 is installed on one side of the top of the worktable 15. This allows for automatic adhesive application to the dimming film, improving application efficiency.

[0030] refer to Figure 3 Both sides of the top of the worktable 15 are bolted with Y-axis electric slides 17. One end of the top of the Y-axis electric slide 17 is slidably connected to an X-axis electric slide 18, and one end of the top of the X-axis electric slide 18 is slidably connected to a Z-axis electric slide 19. The glue applicator 16 is slidably connected to one side of the Z-axis electric slide 19. This facilitates the movement of the glue applicator 16 to different positions, allowing it to evenly apply glue to the top of the dimming film.

[0031] refer to Figure 3 A glue storage tank 20, which works in conjunction with the glue applicator 16, is bolted to one side of the top of the workbench 15. A vacuum mesh plate 21 is bolted to the inside of the workbench 15. The vacuum mesh plate 21 can be used to drain excess sealant to the bottom, thereby preventing excess sealant from accumulating on the workbench 15.

[0032] Brief description of the usage process: By placing the dimming film on top of the worktable 15, the Y-axis electric slide 17, X-axis electric slide 18, and Z-axis electric slide 19 are activated simultaneously to move the adhesive applicator 16 along the X, Y, and Z axes, allowing the adhesive applicator 16 to evenly apply adhesive to the top of the dimming film. After the adhesive application is complete, the drive motor 6 is activated to rotate the synchronous pulley 4, which in turn drives the synchronous belt 5 to transmit power to the lifting frame 7. This allows the lifting frame 7 to move the ring UV lamp 8 up and down. When the ring UV lamp 8 is turned on and slides downwards, it dries and cures the dimming film. When it is turned off and slides upwards, it does not obstruct the worker from removing the finished dimming film.

[0033] Example 2:

[0034] refer to Figure 1, Figure 4 , Figure 5 A coating device for applying sealant to a dimming film is disclosed. A lampshade 9 is bolted to the bottom of a ring-shaped UV lamp 8. A light guide grid 10 is installed inside the lampshade 9. Rotating shafts 12, rotatably connected to the lampshade 9, are welded to both ends of the light guide grid 10. A protective shell 11 is bolted to one side of the lampshade 9. A gear 13 is fixedly sleeved at the end of the rotating shaft 12 near the protective shell 11. A linear rack 14, meshing with the gear 13, is slidably connected inside the protective shell 11. By rotating and tilting the light guide grid 10 inside the lampshade 9, the angle of the ultraviolet light emitted by the ring-shaped UV lamp 8 can be adjusted, facilitating concentrated irradiation of the left and right sides of the dimming film. This reduces incomplete curing of the sealant and improves the coating quality of the dimming film sealant.

[0035] refer to Figure 5 A reflector 3 is adhered to the inner surface of the lamp cover 9. This focuses the ultraviolet light emitted by the ring UV lamp 8, improving the drying and curing efficiency.

[0036] refer to Figure 1 , Figure 3 A control panel 22 is bolted to one side of the base 1, which works in conjunction with the glue applicator 16, the drive motor 6, and the ring UV lamp 8. This facilitates centralized control of the equipment and improves operational convenience.

[0037] Brief description of the usage process: By pushing the linear rack 14 to slide left and right inside the protective shell 11, the linear rack 14 meshes with the gear 13, driving the rotating shaft 12 to rotate, causing the light guide grille 10 to tilt to both sides inside the lamp cover 9. At this time, when the ring UV lamp 8 is turned on to dry and cure the dimming film, the ultraviolet rays of the ring UV lamp 8 can be fixed to irradiate left, right, or vertically downward according to the tilt angle of the light guide grille 10.
