A multifunctional direct-drive horizontally articulated robotic arm

Abstract

A direct drive horizontally articulated mechanical arm (1) comprises: a mechanical arm main body, a first arm body (16) connected to the mechanical arm main body, and a second arm body (17) connected to an end part of one end of the first arm body. The mechanical arm main body comprises a linear module unit (15), a sliding block base (151) and a driving component (12) which are arranged in the vertical direction. An outer side of the sliding block base is connected to a fixing base (153), and a lower part of the fixing base is provided with a first direct drive motor (18); one end of the first arm body is connected to the first direct drive motor, and the other end is provided with a second direct drive motor (19); and one end of the second arm body is connected to the second direct drive motor. The mechanical arm may be used as a desktop level mechanical arm, and a tail end may be provided with a three-dimensional (3D) printer nozzle, a vacuum suction cup, an electric claw, an ink brush, an electric soldering iron, a laser source and the like to achieve various functions such as 3D printing, stacking, writing, welding a circuit board, laser sintering and the like.

Description

[technical field] [0001] The invention relates to the technical field of direct drive horizontal joint mechanical arm products, in particular to a novel multifunctional direct drive horizontal joint mechanical arm which can significantly reduce production costs, has a thin arm body and a coordinated overall appearance. [Background technique] [0002] The horizontally jointed four-axis robotic arm has been widely used at present, and plays a very important role in handling, processing, assembly and other environments. It has the characteristics of flexible movement, compact structure, small space requirement and high repeat positioning accuracy. It can accurately, Quickly reach a point in the space. Compared with the six-axis industrial robot arm, the horizontal joint four-axis robot arm has the advantages of small size, flexibility, and low cost. It will be an inevitable trend to be widely used in the future industrial assembly line. The research of joint four-axis robotic a...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing horizontal joint four-axis manipulators on the market adopt harmonic reducers or RV reducers. The upper and lower Z axes and the rotating R axis are set at the end. The different actions of the four-axis robotic arm in space. This kind of robotic arm has the characteristics of relatively large load, long arm length and high precision, but the price is relatively high. Since the upper and lower Z axes and the rotation R axis are set at the end, the structure of the end The space is relatively large, not suitable for working in small spaces
