Manipulator with get material and pile up function
The invention relates to the field of manipulators, in particular to a manipulator with material taking and stacking functions.
The manipulator can repeatedly do the same action and can never feel tired under the normal condition of the machine, and the manipulator is usually used as an additional device of a machine tool or other machines, such as loading, unloading and transferring workpieces on an automatic machine tool or an automatic production line, replacing tools in a processing center and the like, and generally has no independent control device. Some of the operating devices require direct manipulation by a person, such as a master-slave manipulator, also commonly referred to as a robot, for handling hazardous materials at the atomic energy division door. The application of the manipulator in the forging industry can further develop the production capacity of forging equipment and improve the working conditions of heat, fatigue and the like
At present, in the plate processing process, when the manipulator is used for taking and stacking, the height of stacked plates is increased, the descending stacking height of the manipulator is required to be manually adjusted by a worker when the plates are stacked again, the working efficiency is low, and therefore the manipulator with the material taking and stacking functions is designed to solve the problems.
