[0001] The present invention relates to the field of raw material mixing for producing optical films, and more particularly to a raw material mixing device for producing optical films. Background Art

[0002] Optical films are dielectric materials coated with a thin or multiple layers of polymer adhesive on an optical substrate, thereby altering the propagation characteristics of light along the surface. Optical films are composed of an optical base material and a polymer adhesive, with the latter being the core component. The properties of the adhesive directly influence the film's various physical and chemical properties.

[0040] Referring to Figures 1-12, a raw material mixing device for optical film production includes a tank body 1, a linear module 2 is mounted on the upper end of the tank body 1, a stirring device 3 is slidably connected to the middle of the linear module 2, a scraping device 4 is slidably connected to the middle of the tank body 1, a stopper 5 is detachably connected to the middle of the scraping device 4, a rectangular hole 6 is opened in the middle of one end of the tank body 1, and a linkage device 7 is fixedly connected to the outer end of the rectangular hole 6 on the outer wall of the tank body 1;

[0041] The scraper device 4 includes a cover plate 401, a sliding groove 402 is formed inside the cover plate 401, strip holes 403 are formed inside the cover plate 401 at both ends of the sliding groove 402, a cylindrical hole 404 is formed in the middle of the cover plate 401, a placement groove 405 is formed inside the cover plate 401 at the upper end of the sliding groove 402, two rubber rings 406 are fixedly connected to the outer wall of the cover plate 401 and the inner wall of the cylindrical hole 404, and a pouring hole 407 is formed inside the cover plate 401;

[0042] A servo motor 8 is installed in the middle of the placement slot 405, and a gear 9 is fixedly connected to the output end of the servo motor 8. A snap rod 10 is slidably connected to the middle of the sliding slot 402, and a rack 11 is fixedly connected to the upper end of the snap rod 10. The outer wall of the tank body 1 is located on one side of the linkage device 7 and is fixedly connected to two guide wheels 12. Two spotlights 13 are fixedly installed on one side of the inner wall of the tank body 1. Two photosensitive devices 14 are fixedly installed on the side opposite to the spotlights 13 inside the tank body 1. A discharge hole 15 is opened at the lower end of the middle part of the tank body 1, and a rectangular groove 16 is opened at the outer end of the discharge hole 15 inside the tank body 1. A baffle 17 is slidably connected to the middle of the rectangular groove 16, and one end of the baffle 17 is fixedly connected to two first compression springs 18.

[0043] Referring to Figures 5-9 , the stirring device 3 includes a rod 301, with an agitator 302 fixedly connected to the lower end of the rod 301. An annular slot 303 is defined in the middle of the rod 301, enabling the stirring device 3 to mix and stir the ingredients within the tank 1. The photosensitive device 14 includes a placement box 1401, with a light sensing module 1402 fixedly mounted in the middle. A sealing plate 1403 is fixedly connected to the outer end of the placement box 1401, enabling the photosensitive device 14 to sense the intensity of received light.

[0044] Referring to Figures 3-7 , the linkage 7 comprises a housing 701, with a push rod 702 slidably connected to the center of the housing 701. A second compression spring 703 is positioned in the center of the housing 701. A pull cord 19 is fixedly connected between the ends of the baffle 17 and the push rod 702. A base 20 is fixedly connected to the lower end of the tank 1, with a storage box 21 positioned in the center of the base 20. This allows the linkage 7 to pull the pull cord 19, thereby controlling the movement of the baffle 17. The gear 9 and rack 11 are meshed and connected, and the rectangular hole 6 and the strip-shaped hole 403 have the same longitudinal cross-section. This allows the gear 9 to drive the rack 11 and the snap rod 10 to move between the rectangular hole 6 and the strip-shaped hole 403.

[0045] Referring to Figures 4-10 , a photoresistor, a single-chip microcontroller, and a power supply are mounted in the center of light sensing module 1402. Light sensing module 1402 is electrically connected to servo motor 8, enabling it to generate electrical signals based on the intensity of received light and control the rotation of servo motor 8. A pull cord 19 is located outside the two guide wheels 12 and extends through housing 701, allowing it to rotate within housing 701.

[0046] Referring to Figures 2-8 , the push rod 702 is restrained by the snap rod 10, and the elastic coefficient of the second compression spring 703 is twice that of the first compression spring 18. This allows the snap rod 10 to push the push rod 702 back to its original position, and the second compression spring 703 to overcome the elastic force of the two first compression springs 18 to pull the pull cord 19. The linear module 2 is electrically connected to the light sensing module 1402, and the snap rod 10 mates with the annular slot 303, allowing the light sensing module 1402 to control the movement of the linear module 2, and the snap rod 10 to snap into the center of the annular slot 303.

[0047] During operation, the optical base material and polymer adhesive for optical film production are first poured into the tank body 1 through the pouring hole 407, and the pouring hole 407 is blocked with the stopper 5. At this time, the snap rod 10 is inserted into the rectangular hole 6, so that the scraper device 4 is limited, and the two spotlights 13 are turned on. The light emitted by the two spotlights 13 is respectively irradiated to the corresponding photosensitive devices 14. At this time, due to the uneven mixing of the optical base material and the polymer adhesive inside the tank body 1, the light intensities received by the two photosensitive devices 14 are different, and the resistance values ​​of the photoresistors inside the two photosensitive modules 1402 are different. The linear module 2 is started to make the stirring device 3 start the mixing and stirring work of moving up and down. When the optical base material and the polymer adhesive inside the tank body 1 are evenly mixed, the light intensities received by the two photosensitive modules 1402 become consistent, and the resistance values ​​of the photoresistors inside the two photosensitive modules 1402 become the same size. At this time, the mixing of the optical base material and the polymer adhesive in the tank body 1 is completed;

[0048] The microcontroller inside the light sensing module 1402 sends an electrical signal to control the linear module 2 to drive the stirring device 3 to rise. Then the microcontroller sends an electrical signal to control the servo motor 8 to rotate. The servo motor 8 drives the rack 11 to move through the gear 9, so that one end of the snap rod 10 is disengaged from the rectangular hole 6. At the same time, the other end of the snap rod 10 enters the middle of the annular slot 303, and the push rod 702 moves toward the outside of the housing 701 under the action of the second compression spring 703. The tail of the push rod 702 pulls one end of the pull rope 19 to move, and the other end of the pull rope 19 drives the baffle 17 to move in the middle of the rectangular slot 16. The discharge hole 15 is no longer blocked by the baffle 17, and then the single chip microcomputer sends an electrical signal to control the linear module 2 to mobilize the stirring device 3 to move downward. Since one end of the snap rod 10 is separated from the rectangular hole 6 and the other end of the snap rod 10 is inserted into the middle of the annular slot 303, the scraping device 4 is driven downward by the stirring device 3. The scraping device 4 squeezes the mixed optical film raw material out of the discharge hole 15, and the scraping device 4 also scrapes out the optical film raw material adhered to the inner wall of the tank body 1. The mixed optical film raw material is squeezed out of the discharge hole 15 and falls into the middle of the storage box 21, completing the mixing and scraping of the optical film raw material.

[0049] The single-chip microcomputer then controls the linear module 2 to drive the stirring device 3 upward. The servo motor 8 rotates in the opposite direction, causing the gear 9 to drive the rack 11, causing one end of the latch rod 10 to disengage the annular groove 303 and the other end of the latch rod 10 to insert into the rectangular hole 6. The scraper device 4 is repositioned in the upper half of the tank body 1. The end of the latch rod 10 inserted into the rectangular hole 6 pushes the push rod 702 toward the interior of the housing 701. The end of the push rod 702 no longer pulls the pull rope 19. Under the action of the first compression spring 18, the baffle 17 returns to its original position, blocking the discharge hole 15 and waiting for the next raw material mixing operation. The two pairs of spotlights 13 and the light-sensing device 14 can be used to determine whether the raw materials are evenly mixed, and the scraper device 4 can scrape away any raw materials adhering to the interior of the tank body 1.

[0050] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
