AI Technical Summary

Technical Problem

Existing painting robots for vehicle painting lines face challenges in effectively recovering from nozzle clogging.

Method used

A painting robot with a painting head unit that includes nozzles, a cavity, inlet and outlet passages, and a piezoelectric substrate, which performs recovery control by staggering the droplet discharge from adjacent nozzles by half a cycle when a defective nozzle is detected.

Benefits of technology

Enhances the ability to recover from nozzle clogging in vehicle painting robots, ensuring consistent and high-quality painting performance.

Abstract

To provide a painting robot that can more effectively recover from nozzle clogging in a vehicle painting line. [Solution] The painting head unit 50 includes a painting head 53 equipped with a plurality of nozzles 54 and a piezoelectric substrate 62 for driving to push out the fluid in the cavity from the nozzles 54 as droplets, and a head control unit 100 that controls the driving of the piezoelectric substrate 62. When painting a vehicle, if a particular nozzle 54 is determined to be a defective nozzle 54D with poor droplet discharge, the head control unit 100 performs recovery control to restore droplet discharge from the defective nozzle 54D. When the nozzle 54 adjacent to the defective nozzle 54D is designated as the adjacent nozzle 54A, the recovery control controls the droplet discharge from the defective nozzle 54D and the droplet discharge from the adjacent nozzle 54A to be staggered by half a cycle.
