Abstract

The invention discloses a multi-degree-of-freedom palletizing robot. The palletizing robot comprises a plurality of parallel mechanism closed-loop executing mechanism branch chains and a serial executing mechanism main chain. The mechanism closed-loop branch chains can be used for controlling a main chain connecting rod to move in a plane where a four-rod mechanism closed-loop branch chain is positioned, and spatial movement of a movable platform can be realized via movement of a plurality of parallel connecting rod branch chains and a machine body. Control is realized via composite motion of four closed-loop branch chains and the machine body, and a plurality of connecting rods are connected with the machine body, thereby realizing spatial movement of a tail end executer, small motion inertia of the tail end executer, high dynamics performance and high reliability. The mechanism has the advantages of compact structure and easiness in controlling. Rod pieces can be designed as light rods, the working space of the mechanism is large, and the gravity center of the mechanism is moved backward, thereby keeping the mechanism in a balanced state, and allowing the palletizing robot to be applied to more occasions.

Description

technical field

[0001] The invention relates to the field of robots, in particular to a multi-degree-of-freedom palletizing robot. Background technique

[0002] The traditional series robot has the advantages of simple structure, low cost, and large working space. Relatively speaking, the series robot has low rigidity and cannot be applied to high-speed and large-load occasions; compared with the traditional series robot, the parallel robot has no cumulative error, High precision, compact structure, large bearing capacity, high rigidity and small inertia of the end effector, etc., the driving device can be placed on the fixed platform or close to the fixed platform, so that the moving part is light in weight, high in speed and good in dynamic response; However, the obvious disadvantages of parallel robots are small working space and complex structure. The existing manipulators with partial closed chains in engineering, such as MOTOMAN-K10, did not solve the problems of indu...
