Abstract

The invention provides an ultrasonic vibration rotary drawing-out device, and relates to a drawing-out device for machined parts. The middle of a transmission shaft (21) is fixedly sleeved with a collecting ring (22); the collecting ring (22) is slidably connected with a carbon brush (2); the carbon brush is externally connected with an ultrasonic generator (5); a power wheel (27) is externally connected with a power mechanism (3); a flange at the lower end of the transmission shaft (21) is connected to the upper end of an internal rotary sleeve (17); the upper end of an amplitude-change pole (9) is fixed at the lower end of the internal rotary sleeve; the lower end of the amplitude-change pole (9) is provided with a tubular drawing-out drill (10); a cooling water jetting mechanism is arranged on the lower part of the drawing-out drill; a transducer (16) is arranged in the internal rotary sleeve (17); and a ceramic plate (8) arranged in the middle of the transducer is connected with the collecting ring (22) through an electrode (7) and a wire (4). On the basis of an ultrasonic vibration principle, the accuracy of drawn-out silicon sticks or sapphire bars is high, and the machining cost of the ultrasonic vibration rotary drawing-out device is lower than that of a drawing-out device in the prior art.

Description

【Technical field】 [0001] The invention relates to a digging device for workpieces, in particular the invention relates to a digging device for polycrystalline silicon, monocrystalline silicon and sapphire rod-shaped materials through ultrasonic vibration and rotation. 【Background technique】 [0002] It is known that about 60% of polysilicon solar cells in the photovoltaic market are based on polysilicon wafers. Therefore, the huge amount of polysilicon wafers used is the core force of the photovoltaic industry; Silicon wafers, especially circular silicon wafers, mostly need to be wire-cut through circular silicon rods to form silicon wafers that meet the specified requirements. The existing method is to form large silicon ingots into fragments by beating them, and then use The crucible is melted, and the silicon rods close to the requirements are drawn by using the seed crystal of the guided crystal, and the silicon rods with the required roundness and diameter are obtained ...
