Automatic Painting Without Manual Programming

Lesta EasyProg 3D Scan is a fully automatic system that eliminates manual programming of the painting path. Thanks to a 3D scanner mounted on a carousel, the system autonomously identifies the shape and size of each part and generates the optimal painting path on its own, without needing an operator to program the robot part by part. The underlying technique relates to broader 3D scanning methods.

It is the ideal solution for those working with heterogeneous and non-standardized parts: panels of any thickness and shape (including curved ones), boxes and drawers, disassembled furniture, doors and disassembled kitchens. Every time the part changes, EasyProg 3D Scan adapts automatically, without stopping production to reprogram the cycle.

Operation is simple: the part is loaded onto the positioner, the barcode that recalls the corresponding painting recipe is scanned, and production starts automatically. The system is compatible with industrial painting systems using both liquid and powder.

The work cycle is organized into three main phases. In the first phase, the operator loads the part onto the positioner, without needing to orient or position it precisely. In the second phase, they select the desired recipe, or scan the barcode that recalls a specific one already set. In the third phase, the software automatically generates the painting path, processing the three-dimensional scan of the newly loaded part in real time.

EasyProg 3D Scan manages panels, boxes and drawers with no thickness limits, and can also handle curved and non-standard shaped panels, automatically recognizing their profile thanks to the three-dimensional scan of the carousel-mounted scanner.

Why choose automatic painting without manual programming

In productions handling many parts that differ in shape and size, such as disassembled furniture, doors, drawers and furnishing components, manual robot programming for each product code requires time and specialized staff.

Automatic painting without manual programming eliminates this step: it is the 3D scanner that identifies the shape and size of the newly loaded part, generating a correct painting path on its own without any operator needing to intervene in robot programming.

This approach is particularly useful when parts are not standardized, for example when working with disassembled furniture or irregularly shaped components: a painting cycle designed for a flat, regular part would not guarantee the same finish quality on a curved or complex-shaped part, while the 3D scanner adapts the path to the actual geometry detected each time.

Automatic painting without manual programming also reduces line changeover times: since there is no need to reprogram the robot with every part change, the system can switch from one product code to another in the time needed to load the next part onto the positioner, keeping productivity high even on small batches or with many variants.

EasyProg 3D Scan in Lesta complete systems

EasyProg 3D Scan integrates with Lesta’s other management systems within complete industrial painting systems, handling automatic path generation for the most complex three-dimensional parts. For processes involving panels, boxes and drawers of known and regular height instead, Lesta also offers Easy PROG 2D, the version with a two-dimensional scanner that generates the painting path from just the drawer height entered in the recipe.

Thanks to these solutions, Lesta is able to automate robot programming for both regular parts and parts with more complex geometry, finding wide application in industrial wood painting: disassembled furniture, doors, drawers and furnishing components are among the parts that benefit most from a system able to automatically adapt to different shapes without requiring dedicated programming for every product code.
