Screw Setting Unit

The screw setting unit SEL is modu­lar – it consists of the SEL base module with a DS nutrun­ner that is adapted to the robot and the SEL coupling module with vacuum mouth­piece. The coupling modu­les, desi­gned for diffe­rent screw geome­tries, can be exch­an­ged without tools and are coupled to the base module and pneu­ma­ti­cally locked.

For a mix-up-free place­ment of the coupling modu­les, the SEL inter­ch­an­geable device offers space for up to 5 coupling modu­les – the respec­tive coupling module is stored in a suita­ble holder.

(1) Equip­ped with the SEL screw setting unit, the robot moves to the tool change posi­tion and discon­nects the coupling module. The robot moves the SEL to the bit chan­ging machine to pick up the bit which is suita­ble for the screw joint. (2) The coupling modu­les are in pick-up posi­tion. The robot posi­ti­ons the base module on the coupling module with the correct mouth­piece. The coupling module is locked and connec­ted to the base module.

(3) The screw is picked up by the vacuum mouth­piece with nega­tive pres­sure and placed at the scre­wing joint by the robot – the tigh­tening process is star­ted. The screw is tigh­tened seve­ral turns, then the mouth­piece is lifted up from the screw head and the screw is tigh­tened until the final tigh­tening stage is reached – this prevents torque distor­tion due to fric­tional torques.
