Problems solved by technology

These types of robots generally have the characteristics of high positioning accuracy, fast speed, and large output force. At the same time, this type of robot has high work efficiency and economic benefits in large enterprises with a high degree of automation and relatively fixed production behavior, but these The cost of this type of robot is relatively high, it lacks flexibility and quick adaptability, and it is dangerous, requiring isolation operations
On the other hand, the traditional robot can only be fixed at a certain workflow position of the production line, it cannot be moved, and its position is relatively fixed, its flexible usability is limited, and it cannot be used flexibly
Therefore, when the production of enterprises is adjusted due to the rapid changes in the consumer goods market, this type of robot is not flexible enough, and its dexterity and intelligence are not strong. Negative attitude
[0004] In addition, although robots have gained tremendous development and corresponding policy support in recent years, in fact, most of the production work of small and medium-sized enterprises is still done by manual or traditional robot manipulators, and the intelligence of robots is not enough to replace humans to complete intelligent tasks. In the face of today's complex and changeable production and living needs, collaborative robot technology has attracted more and more researchers and companies' attention.

Abstract

The invention discloses a movable seven-degree-of-freedom intelligent collaborative robot. The robot comprises a movable base and a seven-degree-of-freedom mechanical arm which is arranged on the movable base in a cooperative mode, the movable base comprises a base platform, moving wheels, an adjusting supporting column, a fixing angle piece and a supporting seat, the base platform is composed ofa metal sectional material, the moving wheels are arranged at the bottom of the base platform in a cooperative mode, the fixing angle piece is fixedly arranged at the section connecting and mounting position of the base platform, the adjusting supporting column is arranged on the upper portion of the base platform in a cooperative mode, and the supporting seat is arranged at the top end of the adjusting supporting column in a cooperative mode. According to the movable seven-degree-of-freedom intelligent collaborative robot, an additional axis increased so that the robot can avoid certain specific targets, then a tail end executor can reach a specific position, the kinematics and dynamics characteristics related to the robot can be improved, moreover, the technical limitation that a traditional robot can only be fixed on a certain working process position of a production line for use is changed, the flexible usability of the robot is expanded, and the robot can be better applied to actual production and use.

Description

technical field [0001] The invention relates to the field of movable multi-degree-of-freedom intelligent robots, more specifically, a mobile seven-degree-of-freedom intelligent collaborative robot. Background technique [0002] Enterprises dominated by light industry need a lot of manual work, and urgently need the introduction of robotic automation equipment to improve the production efficiency and quality of the factory, while reducing the labor cost of the factory. However, the working methods of traditional robotic equipment are mainly based on simple and repetitive working methods, while light industrial robots require relatively high positioning accuracy, and have certain requirements for the stiffness of materials and certain flexibility requirements for robot joints, which limits Application of traditional robots in light industry (such as footwear industry). [0003] At present, traditional robots generally have up to six degrees of freedom, among which, the first ...
