ERLS – Enamel Removal Laser System

The Enamel Removal Laser System (ERLS) is a laser-based insulator removal system, which was developed to remove the hard-coated insulator layers (e.g. lacquer) from copper wires without damaging the wires’ material. Employing laser ablation ensures that the insulator will be removed all the way down to the copper resulting in clean metallic surfaces. In oppose to mechanical scraping this process ensures no damage on the wires themselves. The developed laser technology enables the user to process range of insulated wires having different dimensions and insulator materials.

The holding block of the wires is easy to use in industrial environment as it is developed to handle a large scale of product types. Automated camera system and image processing is used for positioning the work piece and for the optimization of the removal time. The software is able to process multiple types of wires with different insulators in the same time.
