[0002] High-thermal-conductivity silicon nitride ceramics are a type of ceramic material with excellent thermal conductivity and mechanical properties. Primarily composed of silicon nitride, they have a higher thermal conductivity than traditional insulating ceramics, making them suitable for applications requiring rapid heat dissipation. Polishing is essential to the processing of silicon nitride ceramics; however, existing polishing equipment often requires workers to clamp and polish each piece of silicon nitride ceramic individually. This not only requires constant power outages and downtime to ensure safe operation, but also significantly impacts overall production efficiency.

[0003] Therefore, there is an urgent need to provide a high thermal conductivity silicon nitride ceramic grinding device to solve the above problems. Utility Model Content

[0010] Through the above technical solution, the output end of the second motor drives the driving gear to rotate. The engagement between the driving gear and the outer gear ring during rotation can drive the outer gear ring to rotate, thereby driving multiple first gears to rotate at the same time, and then the rotation of the first gear can drive the corresponding positioning groove and the silicon nitride ceramic to be processed to rotate at a certain angle.

[0013] The utility model is further configured as follows: a control device is fixedly installed on the mounting frame, and a plurality of reinforcing ribs are fixedly installed between the lower end of the mounting frame and the fixed base.

[0014] The beneficial effects of the utility model are as follows:

[0015] The utility model drives the driving gear to rotate through the output end of the second motor. The meshing between the driving gear and the outer gear ring during rotation can drive the outer gear ring to rotate, thereby driving multiple first gears to rotate at the same time, and then the rotation of the first gear can drive the corresponding positioning groove and the silicon nitride ceramic to be processed to rotate at a certain angle, thereby completing the continuous clamping, grinding, unloading and clamping operations of the silicon nitride ceramic, so that the grinding of the silicon nitride ceramic can realize continuous assembly line processing, which not only saves time and improves the overall production and processing efficiency, but also ensures the safety of the staff in loading and unloading when the device is working.
