Crystal ingot bonding and separating device and method

The invention provides a crystal ingot bonding and separating device. The crystal ingot bonding and separating device comprises a centering disc, a lifting platform, a heating device and a dischargingpart. An object placing hole is formed in one surface of the centering disc, a plurality of pushing blocks are further arranged on the surface of the centering disc in a sliding mode, the sliding direction of each pushing block points to the object placing hole, and a discharging channel communicated with the object placing hole is formed in a side face of the centering disc; the lifting platformis arranged in the object placing hole in a sliding manner; the heating device is used for heating materials placed on the lifting platform; and the discharging part can move in the discharging channel. The pushing blocks can move towards the center of the centering disc along with the rotation of the centering disc, contact a crystal ingot from a plurality of directions, and push the crystal ingot to the center of the ce
