Description

Technical Field

[0001] The present invention belongs to the technical field of polyimide solutions, and particularly relates to a high-performance polyimide solution preparation and supply device. Background Art

[0002] Polyimide is a type of high-performance polymer material with excellent thermal stability, mechanical properties, and chemical stability. Due to its outstanding high-temperature resistance, good electrical insulation, and mechanical strength, polyimide is widely used in fields such as electronics, aerospace, the automotive industry, and microelectronics manufacturing. Polyimide is usually used in the form of a solution, especially in thin film preparation, coating applications, and printed circuit board manufacturing.

[0003] Most of the existing polyimide solution preparation devices are single-axis stirrers. A single-axis stirrer usually can only provide a stirring action in a single direction, which leads to the easy formation of a vortex effect inside the solution, resulting in poor mixing effects in some areas. Especially in the edge and bottom areas of the container, stirring dead zones often occur, causing uneven local concentrations. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-performance polyimide solution preparation and supply device, aiming to solve the problem that most of the existing technologies are single-axis stirrers. A single-axis stirrer usually can only provide a stirring action in a single direction, which leads to the easy formation of a vortex effect inside the solution, resulting in poor mixing effects in some areas. Especially in the edge and bottom areas of the container, stirring dead zones often occur, causing uneven local concentrations.

The rubber sealing plug and the sealing ring are matched with each other.

[0014] As a preferred embodiment of the present invention, an observation window is fixedly connected to the circumferential surface of the preparation container.

[0015] As a preferred embodiment of the present invention, two anti-slip blocks are fixedly connected to the circumferential surface of the preparation container, and anti-slip patterns are formed on the surfaces of the two anti-slip blocks.

[0016] A polyimide solution supply device includes a blanking pipe, a blanking component, and a limiting component. The blanking component includes a semi-circular plate, a connecting rod, a semi-circular block, a first semi-circular groove, a first magnetic block, a second semi-circular groove, and a second magnetic block. The lower end of the preparation container is fixedly connected to the blanking pipe. Two semi-circular plates are respectively fixedly connected to the circumferential inner wall of the blanking pipe. The connecting rod is fixedly connected to the closer ends of the two semi-circular plates. The semi-circular block is rotatably connected to the circumferential surface of the connecting rod. The first semi-circular groove is opened on the circumferential inner wall of the blanking pipe. The first magnetic block is slidably connected in the first semi-circular groove.

[0019] As a preferred solution of the present invention, a filter screen is fixedly connected to the circumferential inner wall of the blanking pipe. An inclined block is fixedly connected to the upper end of the semi-circular plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this solution, after the motor is started, the first gear is driven by the rotating rod. Although the first gear is fixed, it meshes with the second gear on the limiting rod, realizing the transmission of power. Subsequently, the power is transmitted through the second gear, the third gear, and the fourth gear in sequence, driving the connecting rod to rotate. The connecting rod drives the connecting block and the mounting rod to rotate through the power of the fourth gear at its lower end. Multiple first stirring frames on the mounting rod start to rotate in multiple directions, fully stirring the solution. The multi-level and multi-direction stirring design makes the solution mix evenly, improves the product quality, prevents the solution in the preparation container from having dead corners that are not stirred, and increases the speed of solution mixing, improving the work efficiency.

[0022] 2. In this solution, through the magnetic attraction between the second magnetic block and the first magnetic block, the operator can pull the second magnetic block from the outside, causing it to slide within the second semi-circular groove. This design enables the operator to easily adjust the position of the first magnetic block within the first semi-circular groove, thereby driving the semi-circular block to rotate around the connecting rod and achieving precise control over the opening and closing state of the material discharge pipe. This not only simplifies the operation process but also ensures precise adjustment of the solution flow rate. Moreover, the operator can directly pull the second magnetic block from the outside for adjustment, and the switching action can be completed without disassembling any components, greatly improving the operation convenience.

[0023] 3. In this solution, by fixedly connecting the filter screen to the circumferential inner wall of the material discharge pipe, large particle impurities in the solution can be effectively intercepted. This design ensures that the polyimide solution entering the ink cartridge is pure and pollution-free, avoiding nozzle blockage or other printing failures caused by impurities, thereby significantly improving the printing quality and the service life of the device. The design of the inclined block not only reduces turbulence but also optimizes the flow path of the solution, enabling the solution to flow quickly and smoothly from the material discharge pipe into the ink cartridge. This optimized flow path can improve the efficiency of the entire system, reduce the time for the solution to stay in the pipeline, and ensure the freshness and stability of the solution.

[0045] Specifically, please refer to Figures 1-9 , a rubber ring 16 is fixedly connected to the circumferential surface of the preparation container 1, and a clamping groove 17 is formed in the circumferential inner wall of the container lid 2, and the rubber ring 16 and the clamping groove 17 are matched.

[0046] In this embodiment: for the rubber ring 16 and the clamping groove 17, when the container lid 2 is installed on the preparation container 1, the clamping groove 17 tightly presses the rubber ring 16 to form a reliable sealing layer. When it is necessary to remove the container lid 2 to repair the components inside the preparation container 1, the operator can hold the container lid 2 and remove it from the preparation container 1. Moreover, the rubber material of the rubber ring 16 has good elasticity and sealing performance, which can effectively fill the tiny gaps between the container and the lid to prevent leakage of liquid or gas.

[0047] Specifically, please refer to Figures 1-9 , a sealing ring 18 is fixedly connected to the upper end of the container lid 2, and a rubber sealing plug 19 is fixedly connected to the circumferential surface of the sealing ring 18, and the rubber sealing plug 19 and the sealing ring 18 are matched.

[0048] In this embodiment: There is a sealing ring 18 through which personnel can pour a solution into the preparation container 1. There is a rubber sealing plug 19 for blocking the opening of the sealing ring 18. The rubber material can effectively fill any tiny gaps, providing a more airtight sealing effect and preventing the solution from leaking.

[0049] Specifically, please refer to Figures 1-9 , two anti-slip blocks 20 are fixedly connected to the circumferential surface of the preparation container 1, and the surfaces of the two anti-slip blocks 20 have anti-slip patterns.

[0050] In this embodiment: The two anti-slip blocks 20 facilitate the operator to hold the preparation container 1 with both hands for operation. The anti-slip patterns on the surfaces of the anti-slip blocks 20 increase the friction of the contact surface, enhancing the stability and safety of the operator holding the preparation container 1.

[0051] Specifically, please refer to Figures 1-9 , an observation window 21 is fixedly connected to the circumferential surface of the preparation container 1.

[0052] In this embodiment: Personnel can observe the solution preparation situation inside the preparation container 1 through the observation window 21, improving the accuracy when preparing the solution.

[0053] Specifically, please refer to Figures 1-9 , a polyimide solution supply device includes a blanking pipe 22, a blanking component and a limiting component. The blanking component includes a semi-circular plate 24, a connecting rod 25, a semi-circular block 26, a first semi-circular groove 27, a first magnet 28, a second semi-circular groove 29 and a second magnet 30. The lower end of the preparation container 1 is fixedly connected with the blanking pipe 22. Two semi-circular plates 24 are respectively fixedly connected to the circumferential inner wall of the blanking pipe 22. The connecting rod 25 is fixedly connected to the closer ends of the two semi-circular plates 24. The semi-circular block 26 is rotatably connected to the circumferential surface of the connecting rod 25. The first semi-circular groove 27 is opened on the circumferential inner wall of the blanking pipe 22. The first magnet 28 is slidably connected in the first semi-circular groove 27. The first magnet 28 is fixedly connected to the circumferential surface of the semi-circular block 26. The second semi-circular groove 29 is opened on the circumferential surface of the blanking pipe 22. The second magnet 30 is slidably connected in the second semi-circular groove 29.

[0054] In this embodiment: The material discharging pipe 22 serves as the main channel for the solution to flow from the preparation container 1 to the ink cartridge 23. The semi-circular plate 24 provides a support point for the connecting rod 25. The connecting rod 25 is fixedly connected to the closer ends of the two semi-circular plates 24 to form a stable axis for the semi-circular block 26 to rotate thereon. The semi-circular block 26 can rotate around the connecting rod 25 to control the flow of the solution. The first semi-circular groove 27 provides a sliding track for the first magnetic block 28. The second semi-circular groove 29 provides a sliding track for the second magnetic block 30. The first magnetic block 28 and the second magnetic block 30, the material discharging pipe 22 is made of plastic, the second magnetic block 30 is the south pole, and the first magnetic block 28 is the north pole. The second magnetic block 30 and the first magnetic block 28 attract each other magnetically. Personnel can pull the second magnetic block 30 externally to slide in the second semi-circular groove 29. Through the principle of magnetic attraction, the first magnetic block 28 is driven to slide in the first semi-circular groove 27. When the first magnetic block 28 slides, it drives the semi-circular block 26 to rotate around the connecting rod 25, thereby closing or opening the material discharging pipe 22 for discharging and sealing. Personnel can directly pull the second magnetic block 30 for adjustment, and the switching action can be completed without disassembling any components, greatly improving the operation convenience.

[0055] For details, please refer to Figures 1-9 Specifically, the limiting component includes a second limiting groove 31 and a limiting block 32. The two second limiting grooves 31 are opened at the upper and lower ends of the second semi-circular groove 29. The two limiting blocks 32 are respectively slidably connected in the two second limiting grooves 31. The closer ends of the two limiting blocks 32 are fixedly connected to the second magnetic block 30.

[0056] In this embodiment: The second limiting groove 31 provides a sliding track for the limiting block 32 to ensure that the limiting block 32 can only move in a specific direction. The limiting block 32 can make the second magnetic block 30 only slide in the second semi-circular groove 29 and will not fall off by sliding the limiting block 32 in the second limiting groove 31.

[0057] For details, please refer to Figures 1-9 The lower end of the material discharging pipe 22 is provided with an ink cartridge 23. The upper end of the ink cartridge 23 is provided with a threaded ink injection hole 35. The circumferential surface of the material discharging pipe 22 has threads, and the material discharging pipe 22 is threadedly connected to the threaded ink injection hole 35 through the threads.

[0058] In this embodiment: The ink cartridge 23 is used to receive and store the polyimide solution flowing out from the preparation container 1 for use by the printer. The threaded ink injection hole 35 is the channel for the polyimide solution in the preparation container 1 to flow into the ink cartridge 23. The material discharging pipe 22 is threadedly connected to the threaded ink injection hole 35 through the threads, and the material discharging pipe 22 can be easily installed or disassembled by rotating, which is convenient for operation and maintenance.

[0059] For details, please refer to Figures 1-9 The inner circumferential wall of the material discharging pipe 22 is fixedly connected with a filter screen 34, and the upper end of the semi-circular plate 24 is fixedly connected with an inclined block 33.

[0060] In this embodiment, the filter screen 34 can effectively intercept large particulate impurities in the solution, making the solution used during printer printing pure. The inclined block 33 can guide the solution to pass through the blanking pipe 22 more smoothly, reducing turbulence and dead zones, improving the uniformity and stability of the solution flow, and helping the solution to quickly enter the ink cartridge 23 from the blanking pipe 22.

[0061] The working principle and usage process of the present invention: Align the container cover 2 with the preparation container 1 through this device, make the rubber ring 16 precisely match the card slot 17, then press the container cover 2 tightly to ensure the sealing effect. Remove the rubber sealing plug 19, add the required raw materials and solvents into the preparation container 1 through the sealing ring 18, then insert the rubber sealing plug 19 into the sealing ring 18 again to ensure that the sealing ring 18 is completely closed. Then turn on the power supply and start the motor 3. The motor 3 will drive the rotating rod 4 to rotate. The first gear 6 is fixed at the lower ends of the three fixing rods 5 and does not rotate, but meshes with the second gear 10 on the limiting rod 9 to achieve power transmission. The second gear 10 drives the third gear 11 to rotate through the limiting rod 9. The third gear 11 then meshes with the fourth gear 13 to further transmit power to the connecting rod 12. The connecting rod 12 drives the connecting block 37 and the mounting rod 14 to rotate through the power of the fourth gear 13 rotating at its lower end. The multiple first stirring frames 15 on the mounting rod 14 start to rotate in multiple directions to fully stir the solution. Continuously monitor the mixing state of the solution through the observation window 21 to ensure that the solution is uniform and there is no caking phenomenon. At the same time, the second stirring frame 36 at the lower end of the rotating rod 4 also rotates synchronously to further enhance the stirring effect. The position of the second stirring frame 36 is lower than that of the first stirring frame 15, which can stir the bottom of the preparation container 1 to prevent dead zones from remaining in the preparation container 1 without being stirred, ensuring uniform mixing of the solution. When the solution reaches the required mixing degree, turn off the motor 3 to stop stirring. Through the multi-level and multi-directional stirring design, the solution is evenly mixed, the product quality is improved, and the speed of solution mixing is increased, improving the work efficiency.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
