Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, and more specifically, it relates to a mixing device for photoresist production. Background Technology
[0002] In existing technologies, current devices cannot efficiently and conveniently achieve thorough stirring and uniform mixing of photoresist raw materials during use. The raw materials of photoresist typically include high-viscosity resins, photoinitiators, and organic solvents. The characteristics of these materials determine that the mixing process requires extremely high uniformity. However, current devices have the problem of incomplete mixing during the stirring process, which easily leads to uneven material distribution and thus affects the final quality of the photoresist.
[0003] Secondly, the existing equipment also has shortcomings in material transportation. The production process of photoresist requires multiple transfers of raw materials or intermediate products, but the current equipment cannot flexibly and efficiently transport materials. This not only increases the complexity of production operations, but may also lead to material waste and pollution. For example, some equipment is prone to leaving a large amount of material when discharging, which increases the difficulty of cleaning, wastes valuable production resources, and further reduces production efficiency.
[0004] More notably, in actual use, existing equipment suffers from structural design flaws, particularly an imperfect top sealing structure, which leads to material splashing during the mixing process. When the mixing device operates at high speed, raw materials inside the tank may splash to the outside of the tank due to unstable mixing or improper top cover design. This not only wastes valuable raw materials but also seriously pollutes the production environment, increases the burden of cleaning and maintenance, and reduces the efficiency of the entire production process.

[0031] Please see Figures 1-6 A mixing device for photoresist production includes a fixed frame 1, on which a mixing assembly is mounted. The mixing assembly includes a mixing drum 2, a guide rod 3, a top plate 4, a coupling 5, and a third motor 6. The mixing drum 2 is mounted on the fixed frame 1, the guide rod 3 is mounted on the mixing drum 2, the top plate 4 is slidably connected to the sliding rod, the coupling 5 and the third motor 6 are both fixedly mounted on the top plate 4, and the output end of the third motor 6 is connected to the coupling 5. A conveying assembly is mounted at one end of the mixing drum 2. The conveying assembly includes a second conveying drum 7, a first conveying drum 8, and a feed drum 9. The second conveying drum 7 is connected to one end of the mixing drum 2, the first conveying drum 8 is connected to the second conveying drum 7, and the feed drum 9 is mounted on the first conveying drum 8.
[0032] A stirring rod 10 is connected to the coupling 5. Connecting rods 11 are evenly connected to the stirring rod 10. Three connecting rods 11 are grouped together. Mounting seats 12 are connected to the connecting rods 11. Three mounting seats 12 are grouped together.
[0033] A connecting piece 13 is detachably mounted on the mounting base 12, and a bolt 14 is detachably mounted between the connecting piece 13 and the mounting base 12.
[0034] A fixing plate 15 is fixedly installed on the first conveying cylinder 8, a first motor 16 is fixedly installed on the first conveying cylinder 8, and a second motor 17 is fixedly installed on the second conveying cylinder 7.
[0035] Both the output ends of the first motor 16 and the second motor 17 are connected to a conveying rod 18, and a spiral blade 19 is installed on the conveying rod 18.
[0036] In this embodiment, when mixing materials during use, the third motor 6 is started, which drives the stirring rod 10 to rotate via the coupling 5 at its output end. During this rotation, the connecting rod 11 rotates, thereby agitating the connecting plate 13 to mix the materials. When the connecting plate 13 needs to be replaced or cleaned after a period of use, the bolt 14 between the mounting base 12 and the connecting plate 13 can be removed, allowing the connecting plate 13 to be removed from the mounting base 12 for cleaning. Alternatively, after the operation is completed, the above operation is repeated in reverse to complete the fixing process of the connecting piece 13. During the material conveying process, the material is injected into the first conveying cylinder 8 along the feed cylinder 9. Then, the first motor 16 is started to rotate the conveying rod 18 at the output end and the spiral blade 19 thereon, thereby completing the material conveying process and conveying it along the first conveying cylinder 8 to the second conveying cylinder 7. Then, the second motor 17 is started to rotate the conveying rod 18 at the output end to convey the spiral blade 19, thereby conveying the material to the mixing cylinder 2.
[0037] Please see Figure 1-3 As an embodiment of a mixing device for photoresist production, the mixing drum 2 is provided with an adjustment component, which includes a fourth motor 20, a threaded rod 21 and a switch plate 22. The fourth motor 20 is fixedly installed on the mixing drum 2, the threaded rod 21 is connected to the output end of the fourth motor 20 and is threadedly connected to the top plate 4, and the switch plate 22 is slidably connected to the mixing drum 2.
[0038] An observation window 23 is installed on the mixing drum 2, and a first discharge pipe 24 and a second discharge pipe 25 are connected to the bottom of the mixing drum 2.
[0039] A collection box 26 is installed at the bottom of the mixing drum 2. A discharge plate 27 is rotatably connected to both the first discharge pipe 24 and the second discharge pipe 25. A rotating handle 28 is connected to the discharge plate 27.
[0040] More specifically, when it is necessary to inject some materials into the mixing drum 2, the fourth motor 20 is started, which drives the threaded rod 21 at the output end to rotate, causing the top plate 4 on it to slide along the guide rod 3. During the sliding movement of the top plate 4, the third motor 6 and some components on it are raised to the top of the guide rod 3, thereby lifting the mixing components to inject materials into the mixing drum 2 or to clean its interior. When it is necessary to output the materials from the mixing drum 2, the discharge plate 27 is rotated and opened along the first discharge pipe 24 and the second discharge pipe 25 by the rotating handle 28, so that the materials in the mixing drum 2 can be discharged from it, thus completing the material output process.
[0041] In summary, during the use or operation of the overall equipment: when mixing materials, the third motor 6 is started, which drives the stirring rod 10 to rotate via the coupling 5 at its output end. During this rotation, the connecting rod 11 rotates, thereby agitating the connecting plate 13 to mix the materials. When the connecting plate 13 needs replacement or cleaning after a period of use, the bolt 14 between the mounting base 12 and the connecting plate 13 can be removed, allowing the connecting plate 13 to be detached from the mounting base 12. After cleaning or replacing the material, the above operation is repeated in reverse to fix the connecting piece 13. During the material conveying process, the material is injected into the first conveying cylinder 8 along the feed cylinder 9. Then, the first motor 16 is started to rotate the conveying rod 18 at the output end and the spiral blade 19 thereon, thereby completing the material conveying process and conveying it along the first conveying cylinder 8 to the second conveying cylinder 7. Then, the second motor 17 is started to rotate the conveying rod 18 at the output end to convey the spiral blade 19, thereby conveying the material to the mixing cylinder 2.
[0042] When it is necessary to inject some materials into the mixing drum 2, the fourth motor 20 is started, which drives the threaded rod 21 at the output end to rotate. This causes the top plate 4 on it to slide along the guide rod 3. During the sliding movement of the top plate 4, the third motor 6 and some components on it are raised to the top of the guide rod 3, thereby lifting the mixing components to inject materials into the mixing drum 2 or to clean its interior. When it is necessary to discharge the materials from the mixing drum 2, the discharge plate 27 is rotated and opened along the first discharge pipe 24 and the second discharge pipe 25 by the rotating handle 28, so that the materials in the mixing drum 2 can be discharged from it, thus completing the material discharge process.

For all the fixed connections mentioned above, welding is preferred.
