Wolfratshausen – WEBER Schraubautomaten GmbH have revised their successful SEV-P model and offer a modified Pick & Place screwdriving unit – a solution that features fully automated tool changing. The SEV-P can place, change and pick up different tools with a speed of up to 500 mm/s. The screwdriving unit is converted for different screwdriving and joining scenarios within a few seconds – without any human intervention. The components of the SEV-P are designed for the spindle to execute up to three million change cycles. Comprehensive practical tests have shown that there were no appreciable signs of wear on the spindle, the tools and the tool station after this continuous operation. The high number of tool changes were executed reliably at all times.
Pick & Place spindle available in three sizes
WEBER offers these convincing features of the SEV-P in three different sizes: The smallest spindle is designed for lightweight construction robots (up to 3 kg handling load) and low torques (0.1 – 3 Nm). The medium spindle can implement torques between 3 and 30 Nm, while the largest spindle in the series is designed for up to 60 Nm and suitable for industrial robots. The tools are changed with two coupling halves – one in the the bearing block of the spindle, the other on the respective tool. During the coupling process, the two parts are linked or released using mechanical interlocking. The tools are connected to the bearing block with a robust hexagon head bolt and have a funnel-type design, to ensure secure seating in the bearing block and to transfer torques of up to 60 Nm. This connection type is particularly gentle on the material. When developing the SEV-P, WEBER focused primarily on customer requirements in connection with flexibility and different applications/locations. The SEV-P can be used with a WEBER feed system in combination with a Pick & Place separation (TPP), for example. If there is not enough space for installing a feed system in the assembly cell, an additional provision unit – also from WEBER – can be used.
