    SEV-P: Robotic Fastening System with Automatic Bit Change

    Featured Image

    New servo driven spindle expands the WEBER portfolio of lightweight robotic assembly applications. Another WEBER innovation: pick & place system with automatic tool changer.


    With the new SEV-P, WEBER Screwdriving Systems expands its range of servo driven spindles for the field of lightweight robotics. The SEV-P is primarily used as a pick & place system and can process all sizes of individually fed hardware elements. Additionally, the WEBER SEV-P spindle can tighten pre-assembled screws or nuts with the desired torque.

    With the SEV-P, WEBER responded to customer requests for maximum flexibility and a higher degree of automation in screwdriving processes. It is the first supplier worldwide to offer a spindle which conducts a fully independent tool change while mounted on a robotic arm.

    Following the principle and the applications of lightweight robotics, the spindle itself is also designed to be lightweight – the smallest model weighs just 1.5 kg and offers up to 10 Nm of torque. This can be used to implement a variety of different assembly applications. More powerful versions in the SEV-P series can weigh up to 5 kg and reach a torque of up to 60 Nm, always equipped with a corresponding drive and spindle carrier. Due to the vacuum screwdriving technology used, the SEV-P is also suitable for screw connections in hard-to-reach positions.

    Flexibility in assembly processes is becoming increasingly important for customers. WEBER follows these demands with the SEV-P, allowing the use of any number of different exchange tools for processing different fasteners or workpieces.


    New call-to-action

    WEBER once again sets the standard in making assembly processes more effective. This direct customer benefit is realized through the fully automatic tool change. Customers who have already pre-ordered the SEV-P will be using the new ultra-light screwdriving spindle for applications which require a variety of different fasteners, for example in repair stations. The very compact SEV-P is also suitable for assembly processes in tight spaces or for lightweight robots with a maximum payload of 3 kg.

    The SEV-P is combined with standard drives and existing controls from WEBER. Suitable adapter flanges for different robot models are optionally available, as well as a slide for robots without force-controlled tracking.
