Multi-joint robot with linear transmission

Abstract

The invention discloses a multi-joint robot with linear transmission, which comprises a base, a first shaft rotating joint, a second shaft, a third shaft, a fourth shaft and a tail end shaft, a supporting frame is installed on the first shaft rotating joint, the second shaft and the third shaft are each of a linear transmission structure, the second shaft and the third shaft are installed on the supporting frame together, the fourth shaft is hinged to the second shaft and the third shaft to form a joint connecting structure, the fourth shaft moves front and back through transverse linear movement of the second shaft, and the fourth shaft rotates on the vertical face to move up and down through vertical linear movement of the third shaft. Driving parts of the second shaft and the third shaft are respectively arranged on corresponding sliding seats, transverse and vertical actions are realized through mutual combination of transverse and vertical linear motions, the structure is simple, the inertia of a motion load can be reduced, the efficiency is improved, the energy consumption is low, the efficiency is high, and the problem that in order to achieve higher efficiency, a traditional multi-axis robot is heavy in structure and large in dead weight, and consequently the efficiency is affected is solved.

Description

technical field [0001] The invention relates to the technical field of industrial robot equipment, in particular to a multi-joint robot, such as a five-axis, six-axis and other multi-axis robot. Background technique [0002] With the development of technology, robotic equipment has been widely used in many fields such as industrial production, especially multi-axis (ie multi-joint) robots, such as four-axis robots, five-axis robots, and six-axis robots. The degrees of freedom of each axis of the multi-joint industrial robot are completed by the corresponding rotary joints, and the position control adopts polar coordinates to locate at the end position. The disadvantage of this structure is that different rotary joint shafts are used to achieve front and rear expansion and vertical expansion respectively. The drive system of the rotary joint using a reducer + motor not only consumes high energy, but also has a large size and a cumbersome structure, and even requires additiona...

Problems solved by technology

The disadvantage of this structure is that different rotary joint shafts are used to achieve front and rear expansion and vertical expansion respectively. The drive system of the rotary joint using a reducer + motor not only consumes high energy, but also has a large size and a cumbersome structure, and even requires additional configuration. Heavy, the load inertia of the whole machine is large, and the work efficiency is low
