Request

The goal of the project was to create an automated workstation that, without the need for operator intervention, removes a thin metal layer from 3D metallized plastic structures of automotive headlamp components using a laser, followed by 100% quality verification of the laser process according to required parameters and accuracies in hundredths of a millimeter.

Solution

Construction of the technology includes a scanning laser head mounted on a robotic arm, capable of precisely removing metallization from fixed parts positioned on a four-station carousel. Each quadrant performs a specific operation to achieve the shortest possible cycle time. Final product inspection is carried out using neural networks, with the camera module also mounted on the robot.

Results

  • The resulting 3D decoating is tailored to the specific laser technology.

  • An environmentally friendly process that eliminates the need for masking, electrochemical processes, and other conventional methods, along with their associated consumables.

  • The accuracy of the laser itself is in hundredths of a millimeter.

  • Versatility of the system – easy programming for additional product types (e.g., a new headlamp model).

  • Removal of only a defined area without thermally affecting the plastic substrate.
  • Various metal layers or paints and varnishes can be removed without damaging the base material.
  • The substrate can be both transparent and “milky” plastic materials.
