[0002] With the rapid development of the electronic information industry, the performance and quality of electronic materials play a decisive role in the function and reliability of electronic products. In the production process of electronic materials, high-precision coating technology is a key process to endow materials with specific properties. It is widely used in the manufacturing of products such as lithium battery electrode sheets, flexible circuit boards, and optical films. By precisely controlling the coating thickness, uniformity, and coating area, the conductivity, insulation, and optical properties of electronic materials can be effectively improved.

[0003] In the coating production process of electronic materials, the winding process is a crucial step in ensuring the quality of the finished product. After the electronic material roll is coated, it needs to be neatly and flatly wound into a roll for subsequent storage, transportation, and processing. If problems such as material deviation or wrinkles occur during the winding process, it will not only affect the appearance quality of the roll, but may also lead to damage to the internal coating and uneven thickness, seriously reducing the yield and performance of the product.

[0004] In the existing electronic material coating equipment, manual observation is usually relied upon during the winding process. However, the traditional manual observation and correction method depends on the operator's experience, which is slow and has low accuracy. It is difficult to meet the needs of high-speed automated production and thus reduces the practicality of the equipment. At the same time, even experienced employees are prone to negligence due to fatigue under long hours of high-intensity work, resulting in untimely correction. Utility Model Content

[0031] Please see Figure 1-4 This utility model provides a technical solution: a high-precision coating device for electronic materials, including a base 1, a hot air assembly 4, a coating roller 12 and a spraying assembly 14;

[0032] An anti-deviation component is provided on the base 1;

[0033] The anti-correction assembly includes a bidirectional threaded rod 2, a second motor 5, and a fixed bracket 13. Two support plates 8 are fixedly connected to the base 1. The second motor 5 is fixedly mounted on the outer wall of the left support plate 8. Both ends of the fixed bracket 13 are fixedly connected to the outer wall of one side of the corresponding support plate 8. The bidirectional threaded rod 2 is rotatably connected inside the fixed bracket 13. The output end of the second motor 5 extends rotatably into the interior of the fixed bracket 13 and is fixedly connected to one end of the bidirectional threaded rod 2. Two sliding mounting blocks 18 are threadedly connected to the outer wall of the bidirectional threaded rod 2. The outer walls of the tapered blocks on both sides of the two sliding mounting blocks 18 are slidably connected to the inner walls of the tapered grooves opened on both sides of the inner wall of the fixed bracket 13. Hydraulic telescopic rods 20 are installed inside the grooves at the lower ends of the two sliding mounting blocks 18. Guide blocks 19 are fixedly connected to the output ends of the two hydraulic telescopic rods 20. Guide grooves are opened on the outer walls of the opposite sides of the two guide blocks 19.

[0034] Among them, the rear ends of the two support plates 8 are rotatably connected to the unwinding rollers 9. A third motor 7 is installed on the outer wall of the fixed plate at the rear end of the left support plate 8. The output end of the third motor 7 extends rotatably to the outside of the left support plate 8 and is fixedly connected to one end of the unwinding roller 9. Threaded rods 10 are rotatably connected to the slots on one side of the opposite surfaces of the two support plates 8. The mounting seats on both sides of the coating roller 12 are rotatably connected to the outer walls of the corresponding threaded rods 10. The front ends of the two support plates 8 are rotatably connected to the receiving rollers 17. Rotating blocks 11 are rotatably connected to the upper outer walls of the two support plates 8. The ends of the two threaded rods 10 near the rotating blocks 11 extend rotatably to the outside of the rotating blocks 11 and are fixedly connected to one end of the corresponding rotating blocks 11. The outer walls of the front fixed plates of the two support plates 8 are equipped with... The first motor 3 has its output end extending to the outside of the left support plate 8 and fixedly connected to one end of the receiving roller 17. A feed pipe 6 is installed on the outer wall of the left support plate 8. The spraying assembly 14 is installed on the opposite side of the two support plates 8. The end of the feed pipe 6 near the spraying assembly 14 extends to the outside of the left support plate 8 and is connected to the spraying assembly 14. The outer walls of the protrusions on both sides of the hot air assembly 4 are threaded with fixing bolts 15. Fixing bolt slots 16 are opened in the grooves on both sides of the two support plates 8. The hot air assembly 4 is installed on the opposite front side of the two support plates 8 through two fixing bolts 15 and corresponding fixing bolt slots 16. Multiple nozzles on the spraying assembly 14 are arranged at an angle and aligned with the coating roller 12. Multiple air nozzles on the hot air assembly 4 are arranged at an angle.

[0035] Furthermore, when using this device, it is started by connecting to an external power source. First, the electronic material passes over the coating roller 12, then passes through the guide grooves on the two guide blocks 19 and winds onto the take-up roller 17. Then, the output of the third motor 7 drives the unwinding roller 9 to rotate, unwinding the electronic material roll to be coated, allowing the material to smoothly enter the coating process. The output of the first motor 3 drives the take-up roller 17 to rotate, winding up the coated and dried electronic material, completing the material collection for the entire coating process. Simultaneously, the external spraying equipment is connected to the spraying assembly 14 through the feed pipe 6. Then, the paint is conveyed to the spraying assembly 14 through the feed pipe 6. Next, multiple nozzles arranged at an angle on the spraying assembly 14 evenly spray the paint onto the surface of the electronic material in contact with the coating roller 12. In this way, the electronic material moves under the drive of the unwinding roller 9 and the take-up roller 17. When passing over the coating roller 12, the paint is further evenly distributed on the material surface under the action of the coating roller 12, achieving high precision. The coating process continues as the electronic material moves. When the height of the coating roller 12 needs adjustment, the rotating block 11 is turned to rotate the threaded rod 10, simultaneously moving the coating roller 12 up and down to adjust the tension of the electronic material. Finally, an external hot air blower is connected to the hot air assembly 4 via a connector. The hot air blower then sprays hot air from the hot air head on the hot air assembly 4 to dry the coating on the surface of the electronic material, ensuring rapid drying and curing, thus guaranteeing coating quality. Simultaneously, based on parameters such as the width of the electronic material, the second motor 5 is started to rotate the bidirectional threaded rod 2, causing the two sliding mounting blocks 18 to move relative to or towards each other within the fixed bracket 13, adjusting to a suitable initial spacing. Then, if any deviation occurs during the movement of the electronic material, the position of the guide block 19 is adjusted by extending and retracting the hydraulic telescopic rod 20. The guide groove on the guide block 19 guides and corrects the electronic material, keeping it on the correct running trajectory, preventing deviation and ensuring coating accuracy.

[0036] The second motor 5 in the anti-deviation component drives the bidirectional threaded rod 2 to rotate, causing the two sliding mounting blocks 18 to move relative to or towards each other within the fixed bracket 13, adjusting to a suitable initial distance. Then, if a deviation trend occurs during the operation of the electronic material, the position of the guide block 19 is adjusted by the extension and retraction of the hydraulic telescopic rod 20. The guide groove on the guide block 19 is used to guide and correct the electronic material, keeping it on the correct running trajectory, preventing deviation, ensuring coating accuracy, and thus effectively improving the practicality and flexibility of the equipment.
