By using the four positions the logistics can be optimally matched to the speed of the laser welding process. The most common configuration is with two insertion positions where the components are inserted into the jig in two steps, next they go into the welding position, and finally they are removed via the automatic removal manipulator.
Production can be done either in 2 or 4 stages. In the 2-stage operation the insertion is at one position and the welding is at another position, while the remaining positions are not used. If jigs are fitted at all four positions it is possible to switch over very quickly between two different product types. The table has a quick-change system for the jigs so that the downtime time for changing the jigs is reduced to a minimum. This concept has already been proven in practice with a number of customers.
The machine concept is suitable for several different types of laser welding technologies. With this model the welding is done using a handling robot in combination with scanning optics. The robot moves the scanning optics over the components to be welded. The scanning optics weld ‘on-the-fly’ so that a very high level of uptime for the laser source is achieved. The smart air-flow management system ensures optimal welding quality and process speeds.
