Abstract

The invention discloses a series-parallel-type spraying robot comprising a moving platform mechanism and a spraying operation part. The spraying operation part and the moving platform mechanism are matched with each other, and accordingly the movement requirement of the five degrees of freedom in the whole spraying process is finished. Spraying operation platforms and vertical mechanisms are connected through the mode of a ball screw rod linear guide rail sliding table module. The moving platform mechanism is composed of a horizontal moving mechanism body and vertical moving mechanism bodies to achieve moving in the two directions. The spraying operation part forms a three-degree-of-freedom parallel mechanism through the moving platform, ball screw rod branching chains and the fixed platform. A nozzle is installed on the moving platform. The four branching chains of ball screw rods are connected with the moving platform and the fixed platform. Four motors driving the screw rods to rotate are arranged on the fixed platform. The moving platform is connected with the four branching chains. Four motor unit modules drive the screw rods to retract to drive the moving platform to move in the x-axis direction and rotate around the y-axis and z-axis, and accordingly adjusting of the nozzle posture and controlling over the spraying distance can be achieved precisely.

Description

technical field [0001] The invention discloses a novel serial-parallel spraying robot Background technique [0002] Compared with traditional serial robots, parallel robots have better performance in terms of motion accuracy, speed, stiffness, light weight, dynamic response characteristics, error control, etc. Therefore, in industrial fields that have higher requirements for motion trajectories, For example, when spraying surface irregularities, parallel robots have better application prospects. Due to the limitations of power sources and transmission systems, the parallel spraying robots currently on the market or in patents can only spray in a small range of areas. For the spraying of large surface irregular areas, such as body parts, these spraying robots will be difficult to adapt. At present, some schemes use a large gantry-style workbench, and place parallel spraying robots in the upper, lower, left, and right areas of the workbench, and each robot is responsible for ...
