Description

Technical Field

[0001] This utility model relates to the technical field of polyimide material processing equipment, specifically to an integrated device for coating and curing polyimide slurry. Background Technology

[0002] Polyimide, as a high-performance polymer material, has a wide range of applications in electronics, aerospace and other fields. In the preparation process of polyimide materials, it is often necessary to coat the polyimide slurry onto the substrate material and then cure it. Traditionally, the coating and curing equipment are separate, which leads to a complicated production process and requires more equipment investment and a larger production space.

[0003] In the prior art, the coating equipment and the drying chamber are integrated together. The drying chamber includes a pre-drying zone and an imidization curing zone. The coating equipment includes a coating head and multiple transfer rollers. The substrate to be coated is mounted on the transfer rollers. The polyimide slurry in the storage tank is accurately metered and transported to the coating head through a conveying pipeline. The coating head uniformly coats the polyimide slurry onto the surface of the substrate that is being transported by the transfer rollers. The coated substrate then enters the drying equipment along with the transfer rollers to achieve curing.

[0004] However, polyimide slurry will remain on the surface of the transfer roller after long-term use. This residual slurry will gradually accumulate, causing changes in the surface roughness of the transfer roller. When new slurry is applied through the transfer roller, the substrate cannot be evenly adhered to the transfer roller due to the uneven surface, which in turn affects the uniformity of subsequent coating on the substrate. Utility Model Content

[0005] The purpose of this invention is to provide an integrated device for coating and curing polyimide slurry to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated coating and curing device for polyimide slurry, comprising two wing plates, a drying box fixed to the surface of the wing plates, a coating head installed between the two wing plates, a transfer roller rotatably connected to the surface of the wing plates, a fixing plate fixedly connected to the surface of the wing plates, sliding blocks slidably connected to the surface of the fixing plate, a scraper fixedly connected between the two sliding blocks, the scraper adhering to the surface of the transfer roller, and a collection box snapped onto the surface of the fixing plate.

[0007] Preferably, the fixing plate has a semi-circular annular plate structure, and the surface of the fixing plate has a sliding groove, which is an arc-shaped groove. The surface of the fixing plate also has multiple limiting grooves arranged in an array, and the limiting grooves are connected to the sliding groove.

[0008] Preferably, the sliding block has an arc-shaped plate structure, and the sliding block is slidably connected to the surface of the sliding groove. The surface of the sliding block is provided with a spring block hole, and an elastic block is embedded in the spring block hole.

[0009] Preferably, limit blocks are fixedly connected to both ends of the elastic block. The limit blocks are square block structures and are engaged with the surface of the limit groove. The height of the limit blocks is less than half the depth of the elastic block hole and greater than one-third the depth of the elastic block hole.

[0010] Preferably, connecting blocks are fixedly connected to both sides of the surface of the fixed plate, and a slot is opened on the surface of the two connecting blocks at the ends that are far apart from each other. The slot is a square slot and an elastic block is embedded in the surface of the slot.

[0011] Preferably, the elastic block has an "L"-shaped block structure, one side of the elastic block is machined with a bevel, and the elastic block is fixedly connected to the surface of the collection box.

[0012] Preferably, an extension block is fixedly connected to the end surface of the elastic card block away from the collection box, and the extension block has a square block structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The polyimide slurry coating and curing integrated device proposed in this utility model has a scraper on the surface of the transfer roller, which can clean the slurry adhering to the surface of the transfer roller in a timely manner, ensuring the cleanliness of the transfer roller surface, thereby improving the uniformity and quality of subsequent coating. The scraper slides in the sliding groove of the fixed plate through the sliding block, and its position can be adjusted by the cooperation of the limiting block and the limiting groove to adapt to different cleaning needs.

[0015] A collection box is installed at the bottom of the scraper to collect the scraped slurry, preventing pollution of the working environment. The cooperation of the elastic blocks and slots makes the cleaning and maintenance of the collection box more convenient. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0024] Please see Figures 1 to 2 This utility model provides a technical solution: an integrated device for coating and curing polyimide slurry, including two wing plates 1, a drying box 2 fixed on the surface of the wing plate 1, a coating head 3 installed between the two wing plates 1, a transfer roller 4 rotatably connected to the surface of the wing plate 1, a fixing plate 7 fixedly connected to the surface of the wing plate 1, a sliding block 10 slidably connected to the surface of the fixing plate 7, a scraper 6 fixedly connected between the two sliding blocks 10, the scraper 6 adhering to the surface of the transfer roller 4, that is, the cutting edge of the scraper 6 adhering to the surface of the transfer roller 4, the hardness of the scraper 6 being lower than that of the surface of the transfer roller 4, and a collection box 5 snapped onto the surface of the fixing plate 7;

[0025] A scraper 6 is provided on the surface of the transfer roller 4 to clean the slurry adhering to the surface of the transfer roller 4 in a timely manner, ensuring the cleanliness of the surface of the transfer roller 4, thereby improving the uniformity and quality of subsequent coating. The scraper 6 slides in the sliding groove 8 of the fixed plate 7 through the sliding block 10, and its position can be adjusted by the cooperation of the limiting block 12 and the limiting groove 9 to adapt to different cleaning needs.

[0026] A collection box 5 is installed at the bottom of the scraper 6 to collect the scraped slurry, thus avoiding pollution of the working environment. The cooperation between the elastic block 14 and the slot 15 makes the cleaning and maintenance of the collection box 5 more convenient. Example 2

[0027] Please see Figures 1 to 4Based on Embodiment 1, in order to adjust the angle of the scraper 6, the fixing plate 7 is a semi-circular annular plate structure, and the fixing plate 7 and the transmission roller 4 are at the same center. This allows the sliding block 10 to drive the scraper 6 to be arranged along the circumference of the transmission roller 4, ensuring the adhesion effect between the scraper 6 and the surface of the transmission roller 4, which is beneficial for uniform cleaning of the surface of the transmission roller 4.

[0028] The surface of the fixed plate 7 is provided with a sliding groove 8, which is an arc-shaped groove. The surface of the fixed plate 7 is provided with multiple array-distributed limiting grooves 9, which are connected to the sliding groove 8. The sliding block 10 has an arc-shaped plate structure. The multiple array-distributed limiting grooves 9 can cooperate with the limiting blocks 12 on the elastic block 11 to realize the positioning of the sliding block 10 in multiple different positions in the sliding groove 8, so that the scraper 6 and the surface of the transmission roller 4 form different angles to adapt to different cleaning tasks or different conditions of the surface of the transmission roller 4, thereby increasing the flexibility and adjustability of the device.

[0029] The sliding block 10 is slidably connected to the surface of the sliding groove 8. The surface of the sliding block 10 is provided with a spring block hole 16. An elastic block 11 is embedded in the spring block hole 16. The two sides of the elastic block 11 are fixed to the spring block hole 16, so that the elastic block 11 can deform and drive the limiting block 12 to move.

[0030] Limiting blocks 12 are fixedly connected to both ends of the elastic block 11. The limiting blocks 12 have a square block structure and are snapped into the surface of the limiting groove 9. The height of the limiting blocks 12 is less than half the depth of the elastic block hole 16 and greater than one-third the depth of the elastic block hole 16, so that after the limiting blocks 12 are snapped into the limiting groove 9, the elastic block 11 still has a certain elastic deformation space. Half of the limiting blocks 12 is exposed outside the limiting groove 9, which facilitates the pressing operation of the limiting blocks 12. Example 3

[0031] Please see Figures 1 to 5 Based on Embodiment 2, in order to collect the scraped slurry, connecting blocks 13 are fixedly connected to both sides of the surface of the fixed plate 7. The connecting blocks 13 provide the installation base for the elastic locking blocks 14. The surface of the two connecting blocks 13 that are far apart from each other is provided with a slot 15. The slot 15 is a square slot. The surface of the slot 15 is embedded with an elastic locking block 14. The elastic locking block 14 is a 304 stainless steel spring sheet.

[0032] The elastic block 14 has an "L"-shaped block structure, which allows one end to be firmly fixed to the surface of the collection box 5, and the other end to be embedded in the slot 15. One side surface of the elastic block 14 is machined with a bevel, which acts as a guide. When the collection box 5 is brought close to the fixing plate 7, the bevel of the elastic block 14 first contacts the connecting block 13. As it gets closer, the bevel is squeezed by the edge of the connecting block 13, and the elastic block 14 undergoes elastic deformation, allowing the block to slide smoothly into the slot 15. After installation, the elastic block 14 returns to its original shape and is tightly locked in the slot 15, completing a stable connection, simplifying the installation process and improving operating efficiency.

[0033] The elastic block 14 is fixedly connected to the surface of the collection box 5. An extension block 17 is fixedly connected to the end of the elastic block 14 away from the collection box 5. The extension block 17 has a square block structure, which provides a convenient force point for disassembling the collection box 5. When it is necessary to remove the collection box 5 for cleaning, the operator can grasp the extension block 17 and apply force in the direction away from the slot 15 to remove the collection box 5 from the fixing plate 7.

[0034] In actual use, when it is necessary to adjust the position of the scraper 6, first apply external force to press the limiting blocks 12 set on both sides of the sliding block 10. The elastic block 11 is squeezed and changes from its natural state to a compressed state, causing the limiting block 12 to retract into the surface of the spring block hole 16. Then, move the sliding block 10 along the surface of the sliding groove 8 and slide the sliding block 10 to the corresponding position. Release the limiting block 12, and the elastic block 11 loses the squeezing and returns to its natural state from the compressed state. The limiting block 12 pops out and re-locks into the corresponding limiting groove 9, thereby realizing the adjustment of the position of the scraper 6.

[0035] Push the collection box 5 upward along the surface of the fixed plate 7. One end of the inclined surface of the elastic block 14 is deformed by the pressure of the surface of the connecting block 13. When the elastic block 14 slides smoothly into the surface of the slot 15, the elastic block 14 returns to its original shape and the collection box 5 is installed on the surface of the fixed plate 7.

[0036] The transfer roller 4 rotates on the surface of the wing plate 1, driving the material to be coated to move. At this time, the scraper 6 attached to the surface of the transfer roller 4 scrapes off the slurry on its surface as the transfer roller 4 rotates. The close contact between the blade of the scraper 6 and the transfer roller 4 can effectively remove the slurry adhering to the surface of the transfer roller 4, preventing the slurry from accumulating and affecting the uniformity and quality of subsequent coating.

[0037] 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.
