Robot unstacking system and method based on laser ranging radar positioning guidance

Abstract

The invention discloses a robot unstacking system and method based on a laser ranging radar positioning guide. The system and method solve the problems of the limited working scope and stacking heightlimitation of an unstacking robot in the prior art, and have beneficial effects of improving the running efficiency of the whole system and being applied to many occasions. According to the scheme: the robot unstacking system based on the laser ranging radar positioning guide comprises a lifting mechanism, a conveying robot and a control unit, wherein the lifting mechanism drives a distance measuring part to reciprocate in the vertical plane to achieve the movement of the distance measuring part in the vertical direction and to achieve the accurate positioning of the set position in a stacking area, and the lifting mechanism is located at the stacking diagonal extension cord at one side of the stacking area; the conveying robot comprises tongs for griping stacks, and is located at one side of the stacking area and spaced from the lifting mechanism by a set distance; the control unit is separately and electrically connected with the lifting mechanism, the distance measuring part and the conveying robot, wherein the distance measuring part scans layer by layer until objects are detected.

Description

technical field [0001] The invention relates to the field of industrial robots, in particular to a robot destacking system and method based on laser ranging radar positioning guidance. Background technique [0002] Commodities such as food and beverages are mostly packed in cartons or bags and stored in warehouses in pallets. When transporting out of the warehouse, it is necessary to disassemble the goods one by one from the stack and transport them to the designated location, that is, unstacking. [0003] Depalletizing operations are highly repetitive and labor-intensive, and robots are more suitable for such tasks than humans. However, due to certain uncertainties in depalletizing operations, robots have not been able to perform such tasks well for a long time. These uncertainties mainly refer to: the stack type and layer height of the pallet stack, the quantity and position of the goods to be depalletized and other information are unknown. In recent years, people have ...

AI Technical Summary

Problems solved by technology

The system uses multiple sensors to realize three-dimensional target positioning, which simplifies the recognition algorithm, but the impact of light on the system still exists

The above-mentioned system or method, whether it is a vision or a laser solution, the sensors used for identification and positioning are fixed on the top of the stack, and the entire layer is scanned and identified. After the identification is completed, the robot will carry the items one by one, which not only reduces the working scope of the destacking robot and stacking height, which also reduces the overall operating efficiency of the system and limits the use of robot destacking system
