A body painting robot for automobile manufacturing

Abstract

The invention relates to the technical field of industrial robots and discloses a car body spraying robot applied to automobile manufacture. The robot comprises a portal frame, a slide device, a car body and a two-freedom-degree mechanical arm, wherein the slide device is located on the bottom of the center of the portal frame, the car body is fixedly installed on the upper surface of the slide device, a top spraying device is installed fixedly on the top of the portal frame, and lateral spraying devices are fixedly installed on bottom walls of two sides of an inner ring of the portal frame. Through configuration of the top spraying device and the lateral spraying devices, the outer side of the car body which passes the center of the portal frame can be sprayed comprehensively, the spraying robot can have an advantage of large working space just like a series robot and advantages of high rigidity and high bearing capacity of a parallel robot through organic combination of advantages ofthe series robot and a parallel robot, overall performance of the spraying robot is enhanced, the service life of the spraying robot is prolonged, and a maintenance period of the spraying robot is increased.

Description

technical field [0001] The invention relates to the technical field of industrial robots, in particular to a vehicle body spraying robot for automobile manufacturing. Background technique [0002] The rapid development of the modern automobile industry has brought rapid changes in car models, continuous adjustments in car body design, and a substantial increase in production. A large number of spraying robots have been used at home and abroad to replace manual labor. Manual spraying is harmful to the human body and labor-intensive. It is difficult to ensure uniform spraying, and the application of spraying robots helps to achieve full automation, which not only keeps workers away from toxic and harmful substances, but also has uniform coating, guaranteed quality, high efficiency, and no waste of paint. , which greatly improves the spraying efficiency. At present, the vast majority of spraying robots are serial robots with 3-6 degrees of freedom (as shown in the attached Fig...
