[0007] Furthermore, the directional component includes a directional tube fixedly connected to the top of the air storage tube, a second electric push rod fixedly connected to the top of the air storage tube, and a blocking plate fixedly connected to the top of the second electric push rod.
[0008] Furthermore, a wafer limiting block is fixedly connected to the outer wall of the wafer body. The shape of the wafer limiting block is the same as the shape of the loading groove, and the outer wall of the wafer limiting block is slidably connected to the inner wall of the loading groove.
[0009] Furthermore, the top of the mobile platform is machined with a channel, and the rotating column passes through the channel through the fixed platform. The rotating column is rotatably sleeved with the fixed platform. The air storage tube has a "ring" structure and is fixedly sleeved with the rotating column.

When the wafer body is pushed to one side of the wire cutting machine, observe whether the wafer body and the cutting part of the wire cutting machine are aligned. If misalignment occurs, start the air pump. The air pump will take in air through the air inlet pipe and vent air through the air outlet pipe, and then the gas will enter the air storage pipe. The pressure regulator can adjust the air pressure. The second electric push rod is activated, causing the blocking plate to no longer cover the reversing pipe, and the reversing pipe can then release air. The air pressure can drive the rotating column to rotate, and then drive the wafer body to turn via the steering platform. Thus, the device can adjust the position of the wafer body according to the working conditions, and will not cause misalignment with the wire cutting machine and reduce the cutting accuracy even after long-term use.
