Lifting mechanism for material sorting and material sorting robot

Abstract

The invention relates to a lifting mechanism for material sorting and a material sorting robot. The lifting mechanism for material sorting comprises a power part, a vertical fixed arm (1) and a telescopic arm mechanism, wherein the telescopic arm mechanism is arranged in an arm cylinder of the fixed arm (1); the telescopic arm mechanism comprises at least three stages of telescopic arms which arenested and installed stage by stage; the last-stage telescopic arm in the telescopic arm mechanism serves as an execution end to be used for sorting materials; a steel wire rope pulley transmission mechanism is arranged between the fixed arm (1) and each stage of telescopic arm so that the execution end can move by at least three times of travel in the vertical direction when the power part movesby single time of travel. The lifting mechanism can achieve over three times of travel distance by occupying one time of space, requirements for the height of a building on a site are reduced while the requirement for material sorting is met, and the site space occupied by equipment is greatly saved.

Description

technical field [0001] The invention relates to the field of logistics, in particular to a material picking lifting mechanism and a material picking robot. Background technique [0002] In the logistics industry, in order to increase the placement density of items, it is often necessary to place one or several items on the same pallet and stack multiple layers. In the process of stacking and unstacking, a lot of manpower and material resources are wasted. [0003] At present, there are basically two forms of depalletizing of goods, one is to use articulated arm robots to depalletize, and the other is to use Cartesian coordinate robots to depalletize them. Among these two forms of depalletizing, the articulated arm robot depalletizing has a small operating radius and is not suitable for large-scale depalletizing work, while the Cartesian robot can depalletize the goods on any pallet within the working range Therefore, for a larger range of operations, Cartesian robots are ge...

AI Technical Summary

Problems solved by technology

For the turnover boxes used to store items within 50KG in the warehouse, this turnover box is usually small in size for manual handling, and it is also relatively compact when stacked. On the one hand, the existing vertical lifting mechanism is larger in size. It takes up a lot of space in the vertical direction, and it is difficult to meet the size limit requirements of the end effector of the robot. On the other hand, the requirements for guiding and processing of parts are relatively high. If the stability is not enough during operation, it will affect the stacking effect.
