The utility model provides an apparatus for assisting wafer ring to take off wafer, including stage, wafer ring and material taking device, the stage is cylindrical, and the top surface of stage is provided with a through groove in the radial direction, and the through groove penetrates through the lateral surface of stage, the inner side wall of wafer ring is radially protruded to form a step surface, and the wafer is placed on the step surface, and the diameter of wafer ring is larger than the diameter of stage, when wafer ring is placed on the bottom of stage from top to bottom along with wafer, the wafer on wafer ring leaves the step surface and is left on the top surface of stage, and material taking device takes off wafer from the top surface of stage or from the through groove of stage. The utility model has simple structure, and the wafer is supported on the top surface of stage and then taken off, so the operation is convenient, the taking-off efficiency and stability can be improved, the wafer edge is prevented from contacting and rubbing with the inner side wall of wafer ring caused by dumping, and the wafer quality is improved.

The present disclosure relates to the technical field of plate shearing machines, and one embodiment of the present disclosure provides a plate shearing machine with a buffering device for line component processing, which comprises support rods, a material collecting box, a blanking assembly and a material receiving assembly. Two support rods are fixedly installed on the side surface of the plate shearing machine body. The material collecting box is arranged on the support rods through a limiting assembly, and the bottom end of the material collecting box is provided with a plurality of universal wheels. The blanking assembly is arranged between the support rods and the plate shearing machine body, and is used for sliding the sheared plate into the material collecting box. The material receiving assembly is arranged on the material collecting box, and is used for receiving the plate falling into the material collecting box. Through the above technical scheme, the technical problem that the plate lacks a buffering device after being sheared and is subjected to knocking or friction after falling is solved.
