[0039] In summary, this application utilizes an automatic flipping and unloading mechanism 3, which allows the workpiece to be automatically flipped and unloaded onto the synchronous belt conveyor line 13 after grinding without manual intervention. This significantly reduces workpiece loading and unloading time and improves processing efficiency. In addition, the automatic unloading mechanism eliminates the need for manual handling of parts inside the grinding machine chamber, reducing operator exposure to dust, improving the working environment, and protecting the health of operators.

[0040] Furthermore, the locking mechanism can control the individual locking tongue 54 to perform telescopic movements, which can cause the carrying flip plate to flip in different directions. Different synchronous belt conveyor lines 13 are set in multiple directions of the output port 11, which can flip and unload different workpieces on synchronous belt conveyor lines 13 in different directions; this further significantly reduces the workpiece loading and unloading time and improves processing efficiency.
