Large scale laser cutting of plastics
Application: Large-format laser cutting of plastics
Industry: Automotive
How does it all work?
The laser workstation consists of two sections, each operated by one 6-axis industrial robot. In the first phase, the part (door frame) is picked up by the robot from the input conveyor. Then it moves the part under a static laser head where a 200 W CO2 laser cuts off the excessed foil, which extends around the perimeter of the part, with the required accuracy of ±0.2 mm.
The part is then handed over to a second robot, which moves it in front of a 3D scanning laser head with a unique 792 x 718 mm field of view, where all circular cutting of the foil is processed to access mounting holes and holes for audio or airbag wiring. In total, 27 holes are cut in just 15 seconds by using a 400 W CO2 laser. The final part is transferred to the output conveyor of the line for further subsequent application.
Solution
After the installation of laser technology, the customer appreciates the stabilization of quality, especially the repeatability of the production process and the significant improvement in production efficiency. Thanks to the fully automated robotic workstation, the error rate and total time of all operations have been significantly reduced. The customer has also gained a major competitive advantage by saving considerable costs in manpower and consumables that could be used in other parts of the production. In addition, thanks to the multi-functional concept, the entire workstation can be additionally programmed to produce parts for other car models and thus expand the possibilities of its use in the future.
Key benefits
