1. A probe grinding device by acoustic positioning, comprising:
a fixing base, adapted to fix a probe card;
a grinding base, comprising a grinding surface, and the grinding surface facing to the fixing base; wherein when the probe card is fixed on the fixing base, a plurality of probes of the probe card face to the grinding base;
a rotating module, connected to the grinding base;
a moving module, connected to the rotating module;
a motor module, connected to the rotating module and the moving module;
a processing module, electrically connected to the motor module and generating a driving signal to the motor module; wherein the motor module drives the rotating module to rotate the grinding base and drives the moving module to move the grinding base toward the fixing base according to the driving signal;
an acoustic sensing module, electrically connected to the processing module, sensing sound to generate an acoustic sensing signal and transmitting the acoustic sensing signal to the processing module;
a memory module, electrically connected to the processing module, storing a grinding audio data; wherein the grinding audio data comprises a grinding audio;
wherein when the processing module drives the rotating module and the moving module via the motor module, the processing module further determines whether the acoustic sensing signal matches the grinding audio stored in the memory module;
wherein when the processing module determines that the acoustic sensing signal matches the grinding audio, the processing module drives the moving module via the motor module to slow down a moving velocity of the grinding base.
