Automatic feeding and discharging device and method for hard alloy numerical control blades

The invention relates to the technical field of numerical control blade automatic feeding and discharging, and discloses a hard alloy numerical control blade automatic feeding and discharging device and method. In order to solve the problem that the requirement for the matching degree and the precision of all the mechanisms is high due to the fact that the mechanical arms on the mechanical arm need to accurately move to the preset feeding grabbing position, the blade machining position and the discharging placing position correspondingly, a supporting shell is arranged above the base, the supporting shell and the base are connected through a plurality of supporting columns, and the supporting columns are arranged on the supporting shell. The supporting shell is of a cavity structure with an opening in the top end, a feeding belt conveying mechanism and a discharging belt conveying mechanism are arranged above the base, and a feeding groove used for containing one end of the feeding belt conveying mechanism is
