Description

Technical Field

[0001] This utility model relates to the field of photosensitive dry film production technology, specifically a multi-stage drying oven for drying and manufacturing photosensitive dry film master rolls. Background Technology

[0002] The multi-stage drying oven for drying and manufacturing photosensitive dry film master rolls is a core industrial drying equipment specifically designed to serve the production process of photosensitive dry film master rolls in the electronic materials manufacturing process. Its core function is to perform staged and controllable drying and preliminary curing of the substrate after it has been coated with photosensitive resin. It is a key piece of equipment for converting liquid photosensitive coating into solid photosensitive dry film master rolls with stable physical properties and photosensitive characteristics.

[0003] Patent CN119909911A discloses a drying apparatus for producing photosensitive dry film. The apparatus comprises five chambers arranged from left to right within its housing: a preheating chamber, a wetting chamber, a drying chamber, a cooling chamber, and a winding chamber. The temperatures in the preheating, wetting, and drying chambers increase sequentially. The cooling chamber houses a cooling assembly for cooling the photosensitive dry film. Guide rollers are installed in each of the five chambers to guide the photosensitive dry film, allowing it to move gradually from the preheating chamber in a predetermined direction and be wound up by a winding device installed in the winding chamber. This invention, with its preheating, wetting, and drying chambers, effectively improves the drying process through multiple stages, preventing warping or deformation of the photosensitive dry film caused by rapid surface evaporation compared to slower evaporation of moisture within the film layer during high-temperature drying.

[0004] However, the above technical solutions still have the following shortcomings: During use, the tension of the photosensitive dry film changes after drying. This device is not flexible in adjusting the tension of the photosensitive dry film during drying, which can lead to loose winding after drying. During the automatic drying and collection process, loose winding can cause entanglement, damage the photosensitive dry film, and increase the frequency of rework.

[0019] 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. Example

[0020] Please see Figure 1 - Figure 5 This embodiment of a multi-segment drying oven for drying and manufacturing photosensitive dry film master rolls includes an oven body 1. The oven body 1 has several baffles 2 arranged in a straight line. The baffles 2 have discharge ports 3 on their sides. The oven body 1 has several placement rollers 4 arranged inside, with each placement roller 4 located between two baffles 2. The oven body 1 has a placement shaft 5 arranged inside, with a master roll body 6 movably sleeved on the outer wall of the placement shaft 5. The oven body 1 has an adjusting roller 7 arranged inside, and the oven body 1 has an adjusting mechanism through the adjusting roller 7. The top of the oven body 1 is fixedly connected to a support frame 101, and the oven body 1 has a correction component through the support frame 101. The adjustment mechanism also includes a U-shaped groove 8 opened on the side of the oven body 1, and several limiting holes 9 are opened on the side of the oven body 1. The correction assembly also includes an electric telescopic rod 16 disposed below the support frame 101, and a connecting rod 17 disposed below the electric telescopic rod 16; In the drying process of the photosensitive dry film, firstly, the master roll body 6 is placed on the placement shaft 5. Then, the photosensitive dry film is pulled through the adjusting roller 7 and passes through the discharge port 3 on the first baffle plate 2. After the tension is adjusted by the placement roller 4, it passes through the discharge port 3 on another baffle plate 2, thus bringing the photosensitive dry film to the winding point at the other end. Then, the winding device can be activated to automatically collect the photosensitive dry film. The interior of the drying oven body 1 is divided into multiple cavities by multiple baffle plates 2. The heater inside the drying oven body 1 can be adjusted to raise the temperature of different cavities, so that each cavity is heated to the appropriate temperature. The cavity is designed to achieve the drying conditions for the photosensitive dry film. The heater inside the oven body 1 and the winding device at the end are existing mature technologies known to those skilled in the art. Therefore, they will not be described in detail in this embodiment, nor will they be shown in detail in the accompanying drawings of this embodiment. During the drying and winding process, the tightness of the photosensitive dry film will change due to the evaporation of moisture after drying. At this time, by adjusting the position of the displacement adjustment roller 7 through the adjustment mechanism, the adjustment roller 7 can be moved within the U-shaped groove 8 to adjust the tightness of the photosensitive dry film, thereby changing the tension of the photosensitive dry film and preventing it from tangling during the winding process. At this point, the photosensitive dry film was dried in segments, and the tension of the dried photosensitive dry film was adjusted to prevent tangling during the winding process due to changes in tightness, thus avoiding damage to the photosensitive dry film during winding and reducing the frequency of rework.

[0021] The adjustment mechanism also includes a connecting plate 10 disposed on the side of the oven body 1, a movable plate 11 disposed on the side of the connecting plate 10, at least two limiting rods 12 disposed on the side of the movable plate 11 near the connecting plate 10, a spring 13 disposed on the side of the movable plate 11, and a U-shaped groove 14 disposed on the side of the oven body 1, with a connecting plate 15 disposed inside the U-shaped groove 14. One end of the adjusting roller 7 extends into the U-shaped groove 8. The adjusting roller 7 is slidably connected to the U-shaped groove 8. Several limiting holes 9 are arranged in a straight line. At least three rows of limiting holes 9 are provided on the side of the oven body 1. One end of the adjusting roller 7 is fixedly connected to one side of the connecting plate 10. Two limiting rods 12 are symmetrically distributed. The end of the limiting rod 12 away from the moving plate 11 passes through the connecting plate 10. The limiting rod 12 is slidably connected to the connecting plate 10. One end of the limiting rod 12 extends into the limiting hole 9. The limiting rod 12 is slidably connected to the limiting hole 9. One end of the spring 13 is fixedly connected to the side of the moving plate 11. The other end of the spring 13 is fixedly connected to the side of the connecting plate 10. One end of the connecting plate 2 15 is slidably connected to the U-shaped groove 2 14, and the other end of the connecting plate 2 15 is fixedly connected to the side of the connecting plate 1 10. The cross-sectional radius of the U-shaped groove 2 14 is larger than the cross-sectional radius of the limiting hole 9. Please refer to Figure 1 , Figure 2 and Figure 4 When adjusting the tightness of the photosensitive dry film, firstly, pull the moving plate 11 away from the connecting plate 10. At this time, since one end of the connecting plate 15 is slidably connected to the U-shaped groove 14 and the other end is fixedly connected to the connecting plate 10, the connecting plate 15 limits the connecting plate 10, preventing it from being pulled. Then, as the moving plate 11 gradually moves away from the connecting plate 10, the limiting rod 12 will move along with the moving plate 11, leaving the limiting hole 9. As the moving plate 11 moves, the spring 13 will gradually tighten. After the limiting rod 12 leaves the limiting hole 9, the fixing of the adjusting roller 7 is released. At this time, the connecting plate 10 can be pulled to move the adjusting roller 7. The connecting plate 15 will then move within the U-shaped groove 14. (See details below.) Figure 4 U-shaped groove 2 14 and U-shaped groove 1 8 are concentric, that is, U-shaped groove 2 14 encloses U-shaped groove 1 8. That is, when the adjusting roller 7 moves along the trajectory of U-shaped groove 1 8, the connecting plate 2 15 will move synchronously within U-shaped groove 2 14 to provide support for the movement of the adjusting roller 7. After the adjusting roller 7 is moved to the appropriate position, the limiting rod 12 is aligned with the limiting hole 9. Then, the moving plate 11 is released. At this time, the spring 13 will lose tension and drive the moving plate 11 to reset. At this time, as the moving plate 11 resets, the limiting rod 12 will slide on the connecting plate 1 10 and enter the limiting hole 9 to fix the position of the adjusting roller 7. At this time, the position of the adjusting roller 7 was adjusted, and the adjustment range was more flexible and the operation was convenient. The adjustment could be completed quickly, which improved the working efficiency of the device. In addition, the tension of the photosensitive dry film could be adjusted, reducing the possibility of damage to the photosensitive dry film during the drying process.

[0022] The correction assembly also includes a second connecting rod 18 disposed on opposite sides of the first connecting rod 17, a third connecting rod 19 disposed at the bottom of the second connecting rod 18, a sliding plate 20 disposed at the bottom of the third connecting rod 19, and a turntable 21 disposed on the side of the sliding plate 20. The top of connecting rod 17 is fixedly connected to the output end of electric telescopic rod 16, the opposite sides of connecting rod 17 are respectively hinged to the top of two connecting rods 2 18, and the bottom of connecting rod 2 18 is hinged to the top of connecting rod 3 19. The connecting rod 19 is slidably connected to the support frame 101. The bottom of the connecting rod 19 extends into the oven body 1. The bottom of the connecting rod 19 is fixedly connected to the top of the sliding plate 20. The sliding plate 20 is sleeved on the outer wall of the placement shaft 5. The sliding plate 20 is slidably connected to the placement shaft 5. The sides of the two sliding plates 20 that are close to each other are rotatably connected to the sides of the two turntables 21 that are far apart from each other. The sides of the two turntables 21 that are close to each other are in contact with the opposite sides of the mother roll body 6. Please refer to Figure 1 , Figure 2 and Figure 3 After the master roll body 6 is placed on the placement shaft 5, the electric telescopic rod 16 is activated to move the connecting rod 17 upward. As the connecting rod 17 moves upward, the angle between the connecting rod 18 and the connecting rod 17 changes, becoming smaller. Meanwhile, the angle between the connecting rod 18 and the connecting rod 19 changes, becoming larger. At this point, under the limiting effect of the oven body 1 on the connecting rod 19, the two connecting rods 19 will move closer to each other; that is, the two sliding plates 20 will move accordingly. Slide the roller on the placement shaft 5 until the two turntables 21 contact the opposite sides of the mother roll body 6. Then stop starting the electric telescopic rod 16 so that the two turntables 21 are close to each other and contact the mother roll body 6. At this time, the turntables 21 and the sliding plate 20 are rotatably connected. That is, during the rotation of the mother roll body 6, the turntables 21 will reduce the friction with the mother roll body 6 and will not block the rotation of the mother roll body 6. In addition, the position of the mother roll body 6 will be limited to prevent it from shifting during the drying process, which would lead to the final winding failure. At this point, the position of the master roll body 6 on the placement shaft 5 is limited so that it will not shift during winding, further improving the working efficiency and stability of the device.

[0023] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections. Any connection method that can achieve its beneficial effect can be implemented, so the specific structural composition and working principle will not be described in detail in this embodiment.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
