Abstract

Disclosed is a hub paint spraying equipment equipped with a spraying robot having a combined spray gun, comprising a control system, a wheel type recognition system, a brace recognition system, a paint supply device, a quick color changing device, spraying robot, combined spray gun, a cleaning system, a conveying chain and an accessory device. Combined spray gun installed at the end of spraying robot of system is formed by assembling a plurality of spray gun individuals, spraying process and parameter are automatically called by automatic recognition of wheel type recognition system, category of a colored paint is automatically changed, spraying parameter and robot spraying path program are called, and mixed-line intelligent spraying of a hub is realized, so that problems of low utilization rate of equipment due to consumption of a lot of time for replacing colored paint and excessive in-process caused by classification and temporary storage stacking are avoided.

First claim
