LASER PLASTIC WELDING MAXI with robot Innovative and flexible

Laser Plastic Welding Established in 1998, the Leister business unit has many years of experience in laser welding of plastics. Leister is the owner of a number of patents (such as Mask or GLOBO welding) and the only company with expertise in all standard laser plastic welding techniques. The principle of laser welding Joining pressure In laser welding of thermoplastics, sometimes referred to as “laser transmission welding” or “through transmission IR welding” (TTIr), transparent and absorbent parts are bonded together. The laser beam penetrates the transparent plastic and is converted Laser radiation to heat in the absorbing plastic. Since both parts are pressed together during the welding process, heat is conducted from the Weld seam absorbent to the transparent plastic, allowing both materials to melt and create a bond. In addition to the externally applied clamping force an internal joining pressure is also generated through the thermal expansion of the laser-heated plastic parts. The internal and external joining pressures ensure strong welding of both parts. Melt zone Transparent Almost all thermoplastic plastics and thermoplastic elastomers joining part can be welded with the laser beam – including ABS, PA, PC, PP, PMMA, PS, PBT as well as glass fiber reinforced plastic types. The achieved weld seam strength remains within the area of basic material strength. Absorbent Joining pressure joining part GLOBO welding A laser beam is focused at a point on the joining plane via an air bearing, frictionless, freely rotating glass sphere. The glass sphere not only focuses – it also serves as a mechanical clamping tool. While the sphere rolls on the component, it applies continuous pressure at a point on the joining plane. The glass sphere replaces the mechanical clamping device and expands the scope of laser welding to both continuous and three-dimensional applications. Characteristics and application: • Arbitrary joining geometries in two and three dimensions • Welding without a clamping device • Suitable for robotic applications Examples Head-up Display Fabrics Liquid vapor separator 2

MAXI with robot - developed for laser welding of large and three-dimensional components. The easy to use Leister HMI control system not only is the platform for laser specific adjustments but also visualizes and adjusts the robot’s movement within the cell. The system is ideal for GLOBO applications and, for the first time, offers a complete solution from a single source. MAXI with robot The MAXI is a configurable manual turnkey system equipped with all necessary components for laser plastic welding. The Human Machine Interface (HMI) software visualizes the full process and assists while parameterizing the welding process. The HMI shows the welding contour as well as the local limits of the robot within the operation cell. The contour is displayed by a sequence of points where each point can be edited with an addi- tional function like change of speed or laser power. In addition, the HMI transmits process data like laser power, speed and clamping pressure to the system where this data is saved in relation to a specific project. Not only can the system be configured with the robot but also with other motion systems. Furthermore, the system can be equipped with a conveyor belt or with no feeding system at all. • Laser welding system based on a 6-axis-robot • Several applications eligible for production • Process-independent HMI Software • Laser safety class 1 Technical Data laser type diode laser or fiber laser Spot, line, ring, field beam shape DOE, radial laser power < 600 W pilot laser/aiming beam LED working area bis ca. 1450 x 800 mm robot welding speed < 200 mm/s max. working load 14 kg compressed air 6 bar integrated PLC, HMI, controller robot data interface Leister HMI, robot dimensions (L x W x H) 1760 x 1500 x 2200 mm operation cell weight < 2000 kg line voltage 400 V ~ max. current consumption 16 A frequency 50 / 60 Hz environmental conditions 15 – 35°C 3
