Abstract

The invention discloses a robot continuous and automatic paint spraying apparatus for a large work piece, and aims to solve problems in large work piece spraying that the automation degree is low, continuous work is difficult to carry out, a cleaning nozzle is difficult to replace and the work piece cannot be rapidly dried. The tail portion of an industrial robot is fixedly mounted on a movable platform through a pedestal. The movable platform is in threaded connection with a screw and in sliding connection with a rail. A spraying device is mounted at the tail end of the industrial robot. A driving main shaft on a cleaning device is connected to a driving part which is fixedly mounted on an installation seat. A main nozzle is mounted in a nozzle installation hole. The top end of a drying shell is connected to a piston rod of a cylinder. The tail end of the cylinder is connected to the installation seat. A distance sensor is arranged above the drying shell and on the installation seat. The paint spraying apparatus is used for automatically spraying the surface of the large work piece.

Description

technical field [0001] The invention relates to a robot automatic spraying device for the surface of a large workpiece. Background technique [0002] In order to maintain the surface finish and prevent corrosion, most equipment needs to be sprayed before being put into use. For large workpieces such as wind turbine blades, decks and hulls of large-tonnage ships, manual spraying is usually used due to their large geometric dimensions. Artificial spraying is not only inefficient and difficult to guarantee quality, but also affects the health of operators. Robotic spraying technology is widely used, but spraying robots generally work with a fixed base, and it is difficult to complete a single spraying task for large-sized workpieces. However, rapid drying, timely replacement and cleaning of nozzles during the spraying process are all difficult problems to solve. Contents of the invention [0003] The present invention provides a robotic automatic painting equipment for lar...
