the steering gear 24 drives the transmission shaft 26 to rotate through the first belt transmission mechanism 25, and the transmission shaft 26 drives the middle shaft 29 to rotate through the second belt transmission mechanism 28;
the middle shaft 29 drives the roller 31 to rotate through the universal joints 30 at the left side and the right side, and the roller 31 drives the transmission belt 32 to work;
The rotation of the roller 31 is accelerated through the matching of the transmission gear 22 of the residual tooth gear 20 and the diameter difference of a belt pulley in the first belt transmission mechanism 25, so that the transmission distance of the transmission belt 32 is increased;
the roller 31 drives the cam 33 to rotate while rotating, and the cam 33 is matched with the pressing plate 34 through the structural shape of the cam 33 to enable the right end of the pressing plate 34 to be tilted upwards, so that the left end of the pressing plate 34 is lowered;
releasing the support of the support plate 38 and rotating the support plate 38 downward so that the broken silicon wafer material 6 falls along the inclined conveyor belt 32 and the support plate 38 into the waste bin 49 below;
and the completed silicon wafer material 6 is transferred along the transfer belt 32 onto the carriage 46;
the transmission shaft 26 drives the transmission belt 32 to move and simultaneously drives the lifting shaft 40 to rotate through the chain transmission mechanism 39;
the lifting shaft 40 drives the fluted disc 42 to rotate, and the fluted disc 42 drives the lifting gear 43 and the screw 44 to rotate;
the screw 44 drives the bracket 46 to move downwards through cooperation with the nut 45, so that the silicon wafer material 6 on the bracket 46 is lower than the silicon wafer material 6 on the conveyor belt 32, which is not described in detail in this specification and is well known in the art.
