A column-type transfer four-axis
robot includes a support frame, with a hollow column rotatably mounted on top of the support frame. The column has a lifting slider connected to a horizontal large arm, and a small arm rotatably connected to the end of the large arm away from the lifting slider. The small arm has a clamping
flange. An extension rod extending towards the large arm is located above the column, with a lifting
sprocket at the end of the extension rod away from the column. A tension spring
energy storage device is housed within the hollow cavity of the column, and a drive
sprocket is positioned directly above it. One end of a lifting chain is fixed to the large arm, and the other end passes over the lifting
sprocket and the drive sprocket before being fixed to the top of the tension spring
energy storage device. Unlike existing handling equipment, this
robot uses an integrated
column design, assembling all the necessary structures for basic functions, resulting in a simpler overall structure, easier maintenance, and the ability to perform essential functions at minimal cost.
