It includes a curing machine body with a fixed frame fixedly connected to it, and two sliders slidably connected to the fixed frame. It also includes a curing mechanism.

Description

Technical Field

[0001] This invention relates to the field of UV curing technology for functional films, and in particular to a UV curing apparatus for the production of functional films. Background Technology

[0002] Functional films have wide applications in modern electronics, new energy, and display technology. These films are typically formed by coating a substrate with a specific functional adhesive layer or coating, followed by curing to create a stable structure. UV curing technology, due to its advantages such as fast curing speed, low energy consumption, and no solvent emissions, has become a key process in the production of functional films.

[0003] A search revealed Chinese patent CN214294026U, which discloses a UV curing apparatus for laser film production, relating to the field of laser film production technology. It includes a frame, an oxygen-barrier composite film conveying device, and a film pressing assembly. The oxygen-barrier composite film conveying device includes an unwinding frame and a winding frame. The unwinding frame includes a set of side plates, an air shaft, and a drive mechanism. The structural features of the winding frame are consistent with those of the unwinding frame. The side plates are fixed to one side of the frame, with a straight groove at the top and a limiting port at the end of the groove. A through hole is provided on the side plate opposite to the limiting port. A limiting cylinder is fixed to the top of the side plate, and a limiting block is fixed to the output end of the limiting cylinder.

[0004] Based on the above research and existing technology, it was found that existing curing devices with fixed irradiation ranges cannot flexibly adjust the irradiation area width or energy distribution pattern of UV light when dealing with adhesive layers of varying thicknesses. For thicker adhesive layers, insufficient UV light irradiation range or edge energy attenuation leads to incomplete curing in the interior and edge areas of the adhesive layer, affecting the adhesion, abrasion resistance, and reliability of the film. For thinner adhesive layers, an excessively wide irradiation range may cause overexposure in unnecessary areas, leading to material aging, curling, or performance degradation. Furthermore, it is difficult to adaptively adjust the device based on real-time changes in adhesive layer thickness during production or batch-to-batch thickness differences.

[0007] Preferably, the drive unit includes a T-shaped tube fixedly connected to the curing machine body, with movable rods slidably connected to both ends of the T-shaped tube, and fixed blocks fixedly connected to one end of each of the movable rods. The two fixed blocks are respectively fixedly connected to two sliders. A mounting frame is fixedly connected to the curing machine body, and a sliding frame is slidably connected to the mounting frame. A cylinder is fixedly connected to the mounting frame, and the output end of the cylinder is fixedly connected to the sliding frame. A fixed cylinder is fixedly connected to the mounting frame, and a sliding piston rod is slidably connected to the fixed cylinder. The bottom end of the sliding piston rod is fixedly connected to the sliding frame. A fixed tube is fixedly connected to the top end of the fixed cylinder, and a connecting tube is fixedly connected to the top ends of the fixed tube and the T-shaped tube.

[0008] Preferably, each of the four sliding rods is fitted with a telescopic spring, and the two ends of the telescopic spring are fixedly connected to the telescopic rod and the protective cover, respectively.

[0009] Preferably, a return spring is fitted onto each of the two movable rods, and the two ends of the return spring are fixedly connected to the T-shaped tube and the fixed block, respectively.

[0014] Preferably, a connecting spring is sleeved on the sliding member, and the two ends of the connecting spring are fixedly connected to the blower cover and the sliding member, respectively.

[0015] This invention provides an improved UV curing apparatus for the production of functional films, which, compared with the prior art, has the following improvements and advantages: Firstly, this invention, through the setting of the adjustment unit, allows the two protective covers to move away from each other, causing the telescopic rod to extend. The movement of the protective covers drives the extrusion rod to move, which in turn drives the L-shaped rod to move upward. The L-shaped rod then drives the telescopic rod to move upward, which in turn drives the sliding rod and U-shaped rod to move. Since the spring is in an elastic deformation state, as the U-shaped rod moves upward, the spring resets, causing the rotating rod and connecting column to rotate and open. The opening of the connecting column causes the movable plate to enter the arc-shaped plate, increasing the distance between the two movable plates and thus increasing the irradiation range of the UV lamp. The distance between the two protective covers ensures that the irradiation ranges of the two UV lamps do not overlap, but the irradiation spots are close together. When curing thicker adhesives, this invention achieves an adaptive increase in the irradiation range of the UV lamps, while ensuring that the irradiation spots are close but do not overlap, thereby improving the curing effect of the adhesive.

[0016] Secondly, this invention, through the setting of the drive unit, activates the cylinder to drive the sliding frame and the comma scraper upward, thereby enabling the adjustment of the comma scraper. The movement of the sliding frame drives the sliding piston rod upward into the fixed cylinder, allowing the oil in the fixed cylinder to enter the fixed pipe, and then enter the T-shaped pipe through the connecting pipe. The oil entering the T-shaped pipe drives the movable rod to move. Since the diameter of the T-shaped pipe is smaller than the diameter of the fixed cylinder, the oil in the T-shaped pipe moves a greater distance. The movement of the movable rod drives the fixed block, the slider, and the protective cover to move, causing the two protective covers to move away from each other, thus achieving the adjustment of the distance between the two protective covers.

[0017] Thirdly, this invention, through the setting of the blowing unit, starts the fan to guide air into the blowing hood through the air inlet pipe, and then blows it out through the first air outlet and the second air outlet, thereby cooling the cured film. The movement of the protective cover drives the movement of the fixing strip, the movement of the fixing strip drives the movement of the cylindrical rod, the movement of the cylindrical rod drives the movement of the inclined block, the movement of the inclined block drives the movement of the sliding part and the sliding plate, and the movement of the sliding plate increases the overlapping area of ​​the first air outlet and the second air outlet. When curing thicker adhesive, the area of ​​the blowing holes is increased, which improves the cooling effect on the film. Attached Figure Description

[0021] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides an improved UV curing apparatus for the production of functional films. The technical solution of this invention is as follows: like Figures 1 to 8 As shown, this embodiment of the invention provides a UV curing apparatus for the production of functional films, including a curing machine body 1, a fixing frame 11 fixedly connected to the curing machine body 1, two sliders 12 slidably connected to the fixing frame 11, and further including: Curing mechanism, located on the curing machine body 1; The curing mechanism includes an adjustment unit, a drive unit, and a blowing unit. The adjustment unit includes protective covers 13 fixedly connected to the bottom of two sliders 12. Two arc-shaped plates 14 are fixedly connected to the inner wall of each protective cover 13. Movable plates 15 are slidably connected to each of the two arc-shaped plates 14. Partitions 17 are fixedly connected to both ends of each protective cover 13. Fixed posts 18 are fixedly connected to each of the two partitions 17. Two rotating rods 19 are rotatably connected to each fixed post 18. A connecting post 110 is fixedly connected to the bottom end of each rotating rod 19. Each partition 17... Each of the protective covers 13 has an arc-shaped hole 111. One end of each pair of connecting posts 110 passes through the arc-shaped hole 111 and is fixedly connected to the movable plate 15. Two rotating rods 19 on the fixed post 18 are fixedly connected to a spring piece 112. Each protective cover 13 has two sliding rods 2 slidably connected to it. A U-shaped rod 21 is fixedly connected to the bottom end of each sliding rod 2, and the U-shaped rod 21 contacts the two rotating rods 19. A telescopic rod 22 is fixedly connected to the top end of each pair of sliding rods 2. An L-shaped rod 24 is fixedly connected to each telescopic rod 22. One of the protective covers 13... A compression rod 25 is fixedly connected to the upper part of the shield 13. Two L-shaped rods 24 are in contact with the two compression rods 25 respectively. UV lamps 16 are fixedly connected to the inner walls of the two protective covers 13. By adjusting the unit, the two protective covers 13 move away from each other, causing the telescopic rod 22 to extend. The movement of the protective cover 13 drives the compression rod 25 to move, which in turn drives the L-shaped rod 24 to move upward. The movement of the L-shaped rod 24 drives the telescopic rod 22 to move upward, and the movement of the telescopic rod 22 drives the sliding rod 2 and the U-shaped rod 21 to move. Since the spring 112 is in an elastic deformation state, it moves with the U-shaped rod. 21 moves upward, the spring 112 resets and drives the rotating rod 19 and the connecting column 110 to rotate and open. The opening of the connecting column 110 drives the movable plate 15 into the arc plate 14, which increases the distance between the two movable plates 15, thereby increasing the irradiation range of the UV lamp 16. The two protective covers 13 move away from each other so that the irradiation range of the two UV lamps 16 will not overlap, but the irradiation spots are close to each other. When curing thicker glue, the irradiation range of the UV lamp 16 is adaptively increased, and the irradiation spots are close but do not overlap, thereby improving the curing effect of the glue.

[0023] Furthermore, the drive unit includes a T-shaped tube 38 fixedly connected to the curing machine body 1. Both ends of the T-shaped tube 38 are slidably connected to movable rods 39. One end of each movable rod 39 is fixedly connected to a fixing block 310. The two fixing blocks 310 are respectively fixedly connected to two sliders 12. A mounting frame 3 is fixedly connected to the curing machine body 1. A sliding frame 31 is slidably connected to the mounting frame 3. A cylinder 33 is fixedly connected to the mounting frame 3. The output end of the cylinder 33 is fixedly connected to the sliding frame 31. A fixed cylinder 34 is fixedly connected to the mounting frame 3. A sliding piston rod 35 is slidably connected to the fixed cylinder 34. The bottom end of the sliding piston rod 35 is fixedly connected to the sliding frame 31. A fixed tube 36 is fixedly connected to the top end of the fixed cylinder 34. The top ends of tube 6 and T-shaped tube 38 are fixedly connected to a connecting pipe 37. Through the setting of the drive unit, the starting cylinder 33 drives the sliding frame 31 and the comma scraper 32 to move upward. The movement of the sliding frame 31 drives the sliding piston rod 35 to move upward and enter the fixed cylinder 34, so that the oil in the fixed cylinder 34 enters the fixed tube 36, and then enters the T-shaped tube 38 through the connecting pipe 37. The oil entering the T-shaped tube 38 drives the movable rod 39 to move. Since the diameter of the T-shaped tube 38 is smaller than the diameter of the fixed cylinder 34, the movement distance of the oil in the T-shaped tube 38 is increased. The movement of the movable rod 39 drives the fixed block 310, the slider 12 and the protective cover 13 to move, so that the two protective covers 13 move away from each other, thereby realizing the adjustment of the distance between the two protective covers 13.

[0024] Furthermore, each of the four sliding rods 2 is fitted with a telescopic spring 23, and the two ends of the telescopic spring 23 are fixedly connected to the telescopic rod 22 and the protective cover 13, respectively; the telescopic spring 23 is designed to drive the sliding rod 2 to reset.

[0025] Furthermore, a return spring 311 is sleeved on each of the two movable rods 39. The two ends of the return spring 311 are fixedly connected to the T-shaped tube 38 and the fixed block 310, respectively. The return spring 311 enables the movable rod 39 to be reset.

[0026] Furthermore, a comma-shaped scraper 32 is fixedly connected to the sliding frame 31, and a coating roller 312 is rotatably connected to the mounting frame 3. The coating roller 312 and the comma-shaped scraper 32 are compatible. By setting the comma-shaped scraper 32, the sliding frame 31 moves, causing the comma-shaped scraper 32 to move upward, thereby increasing the gap between the comma-shaped scraper 32 and the coating roller 312. By adjusting the comma-shaped scraper 32, different thicknesses of glue can be applied.

[0027] Furthermore, the blowing unit includes an air inlet pipe 4 fixedly connected to the curing machine body 1. One end of the air inlet pipe 4 is fixedly connected to a blowing hood 41. A fixing plate 46 is fixedly connected to the blowing hood 41. A first air outlet 48 is opened on the fixing plate 46. A fan 410 is fixedly connected to the curing machine body 1. The other end of the air inlet pipe 4 is fixedly connected to the air outlet of the fan 410. By setting up the blowing unit, the fan 410 is started to introduce air into the blowing hood 41 through the air inlet pipe 4, and then blown out through the first air outlet 48 and the second air outlet 49, thereby cooling the cured film.

[0028] Furthermore, a sliding plate 47 is slidably connected to the blower cover 41, and a sliding member 42 is slidably connected to the blower cover 41. One end of the sliding member 42 is fixedly connected to the sliding plate 47, and a wedge 43 is fixedly connected to the top of the sliding member 42. A fixing strip 44 is fixedly connected to one end of another protective cover 13, and a cylindrical rod 45 is fixedly connected to one end of the fixing strip 44. The cylindrical rod 45 is in contact with the wedge 43. Multiple second air outlets 49 are provided on the sliding plate 47, and the multiple second air outlets 49 are arranged alternately with multiple first air outlets 48. The movement of the protective cover 13 drives the fixing strip 44 to move, the movement of the fixing strip 44 drives the cylindrical rod 45 to move, the movement of the cylindrical rod 45 drives the wedge 43 to move, and the movement of the wedge 43 drives the sliding member 42 and the sliding plate 47 to move. The movement of the sliding plate 47 increases the overlapping area of ​​the first air outlet 48 and the second air outlet 49. When curing a thicker adhesive, the area of ​​the blower holes is increased, which improves the cooling effect on the film.

[0029] Furthermore, a connecting spring 411 is sleeved on the sliding member 42, and the two ends of the connecting spring 411 are fixedly connected to the blower cover 41 and the sliding member 42 respectively; by setting the connecting spring 411, when the cylindrical rod 45 moves away from the inclined block 43, the connecting spring 411 can drive the sliding member 42 to reset.

[0030] Specific implementation steps: The starting cylinder 33 drives the sliding frame 31 and the comma-shaped doctor blade 32 upwards, increasing the gap between the comma-shaped doctor blade 32 and the coating roller 312. The movement of the sliding frame 31 drives the sliding piston rod 35 upwards into the fixed cylinder 34, allowing the oil in the fixed cylinder 34 to enter the fixed pipe 36, and then through the connecting pipe 37 into the T-shaped pipe 38. The oil entering the T-shaped pipe 38 drives the movable rod 39 to move. Because the diameter of the T-shaped pipe 38 is smaller than the diameter of the fixed cylinder 34, the oil in the T-shaped pipe 38 moves a greater distance. The movement of the movable rod 39 drives the fixed block 310, the slider 12, and... The protective cover 13 moves, causing the two protective covers 13 to move away from each other. The movement of the protective cover 13 causes the return spring 311 to stretch and undergo elastic deformation. The two protective covers 13 moving away from each other causes the telescopic rod 22 to extend via the sliding rod 2. The movement of the protective cover 13 causes the compression rod 25 to move, which in turn causes the L-shaped rod 24 to move upward. The movement of the L-shaped rod 24 causes the telescopic rod 22 to move upward. The movement of the telescopic rod 22 causes the sliding rod 2 and the U-shaped rod 21 to move. At the same time, the movement of the telescopic rod 22 causes the telescopic spring 23 to stretch and undergo elastic deformation. Since the spring piece 112 is in an elastic deformation state, as the U-shaped rod 21 moves... The upward movement of the spring 112 resets the rotating rod 19 and the connecting column 110, causing them to rotate and open. The opening of the connecting column 110 causes the movable plate 15 to enter the arc plate 14, increasing the distance between the two movable plates 15 and thus increasing the irradiation range of the UV lamp 16. The two protective covers 13 move away from each other, preventing the irradiation ranges of the two UV lamps 16 from overlapping, but keeping the irradiation spots close together. When curing thicker adhesives, this achieves an adaptive increase in the irradiation range of the UV lamp 16, while keeping the irradiation spots close but not overlapping, thereby improving the curing effect of the adhesive. The fan 410 is then activated to introduce air through the air inlet pipe 4. Inside the cover 41, the air is blown out through the first air outlet 48 and the second air outlet 49, thereby cooling the cured film. The movement of the protective cover 13 drives the fixed strip 44 to move, the movement of the fixed strip 44 drives the cylindrical rod 45 to move, the movement of the cylindrical rod 45 drives the inclined block 43 to move, the movement of the inclined block 43 drives the sliding member 42 and the sliding plate 47 to move, the movement of the sliding member 42 drives the connecting spring 411 to stretch and undergo elastic deformation, and the movement of the sliding plate 47 increases the overlapping area of ​​the first air outlet 48 and the second air outlet 49. When curing a thicker adhesive, the area of ​​the air outlet is increased, which improves the cooling effect on the film.
