Abstract
The invention relates to the technical field of solar battery cutting apparatuses, in particular to a silicon ingot cutting fret saw applying the thread-breakage protecting method which comprises two guide wheels, cutting threads surrounding the outer sides of the two guide wheels, and two guide wheel protecting plates arranged at the inner sides of the two guide wheels. A contact-alarm-stop device for preventing the thread arch d from exceeding a maximum allowable value thereof is arranged below the cutting thread. After being contacted with the cutting thread, the contact-alarm-stop device automatically alarms and stops the silicon ingot cutting fret saw. By discovering the abnormality of the thread arch in time so as to stop the silicon ingot cutting fret saw and send out alarms, the method and the silicon ingot cutting fret saw prevents the thread breakage and reduces the economic loss to the minimum.
