Laser marking and Leakage test in one machine

About one year ago, LASIT started the technical project in order to produce a laser marker able to mark turbocharger volutes and carry out the Leakage Test on components.

The machine had to fit into a production line and one of the main demands was the realization of a customized software that interfaces with the company’s database.

These were the goals set in mind when we developed the Flypress: a laser marking machine equipped with an ATEQ Leakage test system, a 30Watt optical fiber laser, YZ motion axes and a Cognex vision system.

The machine’s structure is made of steel and the marking cabin has an automatic front door, equipped with optical barriers that protect the operator when loading the component.

The volute of the turbocharger is inserted into the machine on the processing template, which was implemented based on the Poka-yoke logic, in order to avoid any possible error.

The Flypress is also suitable for the laser marking of volutes featuring different heights: this is possible by replacing the spacer and changing the position of the laser head.

Leakage Test

There are two pistons that close the volute chamber to carry out the Leakage Test in the cabin.

The machine is interfaced with an ATEQ to verify the test result on both outputs (based on the surface, the air pressure is automatically regulated by a solenoid valve).

If the result of the Leakage Test is negative, the component will be rejected. If the result is positive, the Flypress will proceed with the laser marking. Once the quality of the marking has been verified, the camera will return to position and the pistons will release the components.
