Laser Cleaning

In many cases, cleaning with laser scanners not only appears to be an ecologically sensible alternative to conventional cleaning methods in industry, the process also convinces by the material-friendly, faster and more efficient treatment of surfaces. The desired cleaning fields can be positioned and controlled with absolute precision. So what solutions does RAYLASE offer for this cleaning application?

In automotive production, laser cleaning is not only used for cleaning, but increasingly as a pre-treatment for the functionalisation of surfaces. It can be used to improve the adhesion of adhesives or to achieve optimum surface conductivity. This gentle method is also often the best choice for restoration work and mold cleaning. 

Hairpins are responsible for safe energy transmission in electric motors. In order to ensure reliable power transfer later on, the hairpins must be freed from corrosion-protective coatings at their contact points. With its precision and speed, contact free cleaning by means of laser is far superior to the chemical or mechanical removal process and can be automated just as easily.

Due to the increasing demand for lithium-ion batteries for electric vehicles and consumer electronics devices, the efficiency of battery production is becoming increasingly important for machine builders and battery manufacturers. A very important manufacturing step in battery production is to selectively remove carbon / graphite-based coatings on the battery foil and expose the underlying aluminum or copper foils for the subsequent process. The goal in this case is a high removal rate, i.e. cleaning without damaging the very thin foil underneath. A high-speed scanning solution with a high-energy ns-pulsed laser offers an optimal, precise and, above all, fast solution here.

The technical approaches to solving this cleaning task are currently still very diverse. There is currently a broad range of approaches, from a single-stage cleaning process with a scan system and a laser to multi-stage processes with different scan systems and laser types. The removal can be implemented both statically and dynamically (processing-on-the-fly). The range of hairpins extends from round to rectangular in different dimensions with challenging hatching requirements for the scan systems.To clean all sides of the hairpins there are multiple solutions possible.
