Lesta painting robots are engineered for large-scale industrial applications, enabling precise and uniform painting of oversized and complex parts such as trucks, trailers, buses, and steel structures. By integrating floor-mounted and overhead handling carriages, these robots extend their operational range and maintain high accuracy across large surfaces.
The Italian manufacturer of self-learning robots Lesta is making waves with its painting robots for large-scale systems, renowned for handling parts with impressive dimensions and complex geometries. More than simply selling robots, Lesta develops solutions that address real-world industrial challenges, helping companies optimize production cycles while ensuring top-quality results.
A concrete example
is the use of Lesta robots on overhead and floor-mounted carriages in painting systems for trucks, trailers, and steel bars. These systems can move along multiple axes and paint parts up to 14.7 m long, 6.6 m deep, and 3 m high.
The challenge: automatically painting large parts
Our robots are ideal for companies that produce large vehicles such as trucks, buses, and trailers, as well as for shipyards and boat manufacturers.
In these cases, the main challenge is ensuring precision and uniformity across large surfaces and complex components — operations made possible through the combined use of carriages and Lesta robots.
Thanks to their versatility, Lesta robots offer another key advantage: they can be easily integrated into existing systems, allowing complex parts to be painted without the need to modify the entire plant.
The solution: handling carriages for industrial robots
To expand the robots’ operating range, Lesta designs and manufactures handling carriages, essential for ensuring precision and repeatability even on large parts.
Floor-mounted carriages
- Rail system with motorized platform.
- The robot moves along the rail and records its movements during the self-learning function, enabling the painting of long or complex parts without losing accuracy.
Overhead carriages (gantries)
- Bridges supported by uprights with rails, under which the robot is mounted upside down.
- They allow longitudinal, vertical, and horizontal movements, increasing the coverage of the work area.
- They can add additional axes to the robot, enhancing the versatility of industrial painting for large parts.
All carriage-based systems are equipped with the Lesta “Follow Me” plug-in, which allows the robot to naturally follow the operator during path recording, making it easier to program large and complex surfaces.
Lesta PAINT STUDIO 3.0: software for offline robot programming
Lesta PAINT STUDIO is a CAD/CAM software developed for the offline programming of painting robots, designed to optimize production cycles and simulate complex paths on large parts.
Main features
- Interactive 3D environment for importing part models, even very large ones.
- Creation and simulation of painting paths with automatic grids and path connections optimized for large surfaces.
- Verification of the robot’s reach limits and cycle times, essential for large components.
- Adjustment of painting parameters such as speed, acceleration, distance from the part, angle, and gun settings, adapting the process to any geometry.
- Ability to record key points by physically moving the robot or by creating 3D geometries directly within the software, enabling complex and precise painting paths.
- Compatible with systems not equipped with Lesta robots, for both liquid and powder coating applications.
