Viper Robot now with Active Vibration Control

Faster Positioning for Shorter Cycle Times

Engel Austria GmbH has equipped its viper linear robots with an active vibration control. Thanks to the new feature the viper linear robots not only detect their own oscillations, but can also react to vibrations that are caused by external influences. Actively compensating for oscillations during the running process increases positioning speed and reduces cycle time.

Thanks to the new active vibration control, the viper linear robots not only detect their own oscillations, but can also react to vibrations that are caused by external influences (figure: Engel)

In mobile phones, 3-D motion sensors have long become standard equipment. Now the Engel viper robots also use this technology and thus significantly boost their performance and efficiency. While up to now, the robots own expected oscillations were calculated for vibration control, external influences can now also be compensated for online. Thanks to the active vibration control, the viper robots reach a stable working position more quickly and operate with significantly greater positioning accuracy, which is important for such tasks as placing insert pieces or transferring pre-molded parts.

All Engel viper robots will be equipped with active vibration control starting from size 20 up to the largest viper 120 robots with a load capacity of 120 kg. The viper 40 and 60 robots made the start in time for Fakuma 2015.

In revising its linear robot series, Engel has not just increased the positioning speed, but has also boosted the overall performance and efficiency. The new multidynamic drive package ensures that the robots automatically adapt their dynamics to the real weight load. Thus the viper robots operate faster when bearing lighter loads and slower with heavier ones. The efficiency control function also takes the cycle of the injection molding process into account. Within only three cycles, the viper achieves the optimal dynamics for the respective injection molding process, for example by reducing its own speed corresponding to a long cooling stage without increasing the overall removal time. While the machine operator previously had to calculate the optimal handling speed for each process individually and set it manually, the viper robots now automatically manage this themselves.
