The answer comes from the new solution designed and produced by the Fiam Autovite division for a customer who is a leading name in the baby accessories business. It is essentially a hanging arm jointed to move freely 4 ways that meets the need to introduce an articulated support on the existing production line conveying the components to allow the operator to perform ergonomic tightening by means of the self-feeding tightening system used. This request is further confirmation of the importance of ergonomic design even when it comes to automated assembly processes, i.e. where operator intervention is reduced to a minimum. In this specific solution, the load-bearing structure has been built to "straddle" the production line to afford the utmost ease of handling: as a matter of fact, it can be rotated and translated at various points (as indicated by the arrows in the picture here). More specifically, the way the screwdriver is supported provides unbeatable freedom of rotation both on the vertical and horizontal plane. Moreover, since all tightening jobs are to be performed on the vertical surface of the components to be assembled, the straight screwdriver used has been "adapted" and fitted with a pistol grip: this means the hand-arm system is positioned correctly, effectively eliminating any stress the operator would otherwise be forced to endure.
