摘要
Title Painting Robot - Forearm Systems Design

Abstract
In today's large-scale manufacturing, enterprises in order to improve productivity, attach importance to the degree of automation of the production process, the painting robots as an important member in automated production lines have been gradually recognized and adopted.
This paper briefly describes the research background, the meaning and the current situation of the painting robot. Then, the paper gives the overall scheme of design, determines coordinates of the whole joint, uses a stepping motor to drive, selects a ball screw, chain sprockets and bevel gears three kinds of transmission type and use spring to balance so that work out a reasonable design programs. Finally, design and calculation of the arm system, through the stress analysis of the arm system in order to design the structure of forearm and wrist, calculate moment of force of the joint rotation, select and design to meet the requirements of the motor, ball screw, sprocket, cone gears, springs and so on. Determined the installation location of the various parts ponents, so as to realize the movement requirements of arm pitch of 30 degrees, wrist swing of 120 degrees and the wrist twirl of 120 degrees.
