Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a device for coating aerogel onto the surface of spherical silicon micropowder. Background Technology

[0002] In high-end fields such as electronic packaging and aerospace, spherical silicon micropowder has become a key material due to its excellent dielectric properties, high filling capacity, and low coefficient of expansion. However, its high surface activity and easy agglomeration characteristics limit its application effect. Aerogel coating can significantly improve the hydrophobicity, thermal stability, and mechanical properties of spherical silicon micropowder. However, traditional coating processes have problems such as uneven coating, difficulty in controlling the thickness of the aerogel layer, and low production efficiency. Therefore, it is necessary to develop a special aerogel coating equipment for the surface of spherical silicon micropowder to meet the dual requirements of product quality and efficiency in industrial production.

[0003] During equipment use, insufficient dispersion of silicon micropowder within the reaction chamber leads to uneven aerogel coating, affecting product performance consistency. Precise control of the aerogel precursor spraying amount is difficult, resulting in coatings that are either too thick or too thin. The equipment also consumes a lot of energy during operation. Existing equipment optimizes the reaction chamber structure by combining multi-stage stirring and airflow dispersion to improve silicon micropowder dispersion, and introduces high-precision metering pumps and automated control structures to achieve precise control of the precursor spraying amount. However, these devices are complex, increasing purchase and maintenance costs. The stirring effect is not ideal, and the amount of aerogel solution used is difficult to guarantee, reducing coating quality and failing to meet usage requirements. Utility Model Content

[0034] Specifically, the support plate 201 is the foundation of the entire mechanism.

The rotating ring 202 is connected to the feeding port 203, which facilitates the addition of materials and enables more flexible operation and material supply. The solution tank 204 is the part of the spraying mechanism 2 that stores and supplies solutions.

[0037] Please see the appendix Figure 1 and attached Figure 5 A feeding pipe 17 is fixedly connected to the top front left side of the solution tank 204, and a protective cover 18 is fixedly connected to the top of the feeding pipe 17. Multiple decorative strips 19 are fixedly connected to the front and rear sides of the solution tank 204, and the multiple decorative strips 19 are arranged at equal intervals. An observation window 20 is fixedly connected to the left side of the solution tank 204, and multiple support blocks 21 are fixedly connected to the bottom front and rear sides of the solution tank 204.

[0038] Specifically, the feeding tube 17 on the solution tank 204 is used to add the required aerogel solution. The protective cover 18 ensures the safety and cleanliness of the inside of the solution tank 204. The decorative strips 19 are evenly spaced, which not only increases the aesthetics but also plays a certain role in structural reinforcement.

[0039] Working principle: Multiple drive shafts 4 are rotatably connected to the support frame 1, and auxiliary wheels 5 are connected to the outer wall of the drive shafts 4, so that the mixing tank 8, which is rotatably connected to the support frame 1 through the mounting frame 7, can rotate stably. When the servo motor 3 starts, the drive shaft 4 at its output end rotates, driving the auxiliary wheel 5 and the gear 6 to rotate together. Since multiple tooth blocks 9 are fixedly connected to the mixing tank 8, and the tooth blocks 9 mesh with the gear 6, the mixing tank 8 can be driven to rotate, thereby stirring the internal structure. In addition, multiple stirring rods 10 are fixedly connected to the inner wall of the mixing tank 8, which further improves the stirring effect. This structure is simple, reduces costs, and improves the uniformity and efficiency of stirring, making the subsequent coating effect more of a quality and meeting the usage requirements.

[0040] The support plate 201 fixed on the support frame 1 allows the rotating ring 202 to be rotatably connected to the mixing tank 8, thereby fixing the feeding port 203 to the structure. During the mixing process, the aerogel solution inside the solution tank 204 is pumped into the water pipe 206 by the water pump 205, and then sprayed into the interior of the mixing tank 8 through the nozzle 207 installed on the water pipe 206, thereby precisely controlling the spray volume and coating during the mixing process. This structure reduces manpower, improves the accuracy of solution use, ensures the coating effect, and meets the coating requirements.
