A robot for lifting heavy objects

Abstract

The invention discloses a robot for lifting a heavy object. The robot for lifting the heavy object comprises a robot body and a clamp, wherein the robot body comprises a base, a rotating support, a first servo motor, a big arm, a V-shaped frame, a first link, a crank, a second link, a forearm, a second servo motor, a second parallelogram mechanism, a third servo motor and a clamp mounting seat, and three parallelogram mechanisms are formed through hinge of hinge shafts; an end effector is arranged on the clamp mounting seat; and the clamp is mounted on the end effector. According to the robotfor lifting the heavy object, the position of the clamp can be adjusted through the mode that the first servo motor drives the rotating support to rotate; the large-scale transfer of the clamp is achieved through the mode that the second servo motor drives the big arm to swing up and down and through the cooperation of the parallelogram mechanisms; the position of the clamp can be finely adjustedthrough the mode that the third servo motor drives the crank to swing up and down and through the cooperation of the parallelogram mechanisms; and therefore, the clamp can keep moving smoothly withoutworrying about rollover of the heavy object.

Description

technical field [0001] The invention belongs to the technical field of logistics cargo loading and unloading, and more specifically relates to a robot for lifting heavy objects. Background technique [0002] At present, in the field of modern logistics loading and unloading, the loading and unloading equipment has a single form, and the loading and unloading efficiency and automation level are low. In industrial production lines, robots are often used instead of manpower to carry workpieces and arrange them neatly on pallets, which can greatly improve production efficiency, ensure stability, reduce labor intensity, and prevent major safety accidents. The traditional four-axis palletizing industrial robot cannot complete the lifting operation of large boxes or cylinders with great height requirements due to the limited arm length, limited load capacity, and the limitation of the rotation range of the boom; The robot is not only expensive, but also has a low load-carrying cap...

AI Technical Summary

Problems solved by technology

In logistics handling, especially when there is a certain height requirement for lifting objects, it is not suitable to use palletizing robots to stack or load and unload goods.
