Problems solved by technology
Generally speaking, the hardware cost of the seven-axis robotic arm is high, the time required for manufacturing is long and the labor cost is high; at the same time, the mechanical structure of the seven-axis single arm is heavy; therefore, the standard weight of the seven-axis dual-arm collaborative robot is usually large and The load is small; and, due to the heavy structural weight of the seven-axis manipulator, the moment of inertia of the joint is large; and the shape of the seven-axis manipulator is relatively complex, and multi-axis linkage is required during movement, so the motion acceleration is low; in addition, for the seven-axis dual-arm For collaborative robots, the joint moment load is high and the kinematics model is relatively complex, which is not conducive to the realization of collision detection based on current monitoring
If a force sensor is added, the cost of the manipulator will inevitably increase

A double-arm collaborative robot comprises a base, stand columns which are arranged on the base in the vertical direction, a pair of vertical adjusting mechanisms which are respectively arranged on the stand columns, and a pair of mechanical arms which are assembled to the vertical adjusting mechanisms respectively. The vertical adjusting mechanisms are used for adjusting the height positions of the corresponding mechanical arms, and each mechanical arm is provided with at least two movable joints with rotating shafts parallel in the axial direction. The double-arm collaborative robot has the advantages of being simple in single-arm structure, small in self weight and high in load capacity, and a low-cost solution is easy to achieve.
Description
technical field [0001] The invention relates to the technical field of robots, in particular to a dual-arm collaborative robot. Background technique [0002] A collaborative robot is a robot that can interact with people in a shared space or work safely with people at close range. It is mainly different from traditional industrial robots in terms of safety, interactivity and ease of use. The safety feature of collaborative robots is mainly the collision detection function, which can prevent harm to people; the interactive feature is light weight, easy installation, and easy to interact with people; in terms of ease of use, collaborative robots teach programming Convenient and easy to use. [0003] Most of the collaborative robots currently on the market are single-arm collaborative robots, that is, a collaborative robot system contains only one collaborative robot arm. Compared with single-arm collaborative robots, dual-arm collaborative robots are more like humans, and th...
