Abstract
In a soldering apparatus using a rotary station, a component holder is lowered and/or moved vertically by a stepper motor drive. A motor, lowers a drive shaft by a lead screw, and a second motor rotates the shaft via a toothed bearing wheel, the shaft having a hexagonal cross-section. A pivotable lobe couples the shaft to a shaft to lower the component holder and to rotate it (by rotation of shaft). The stepper motors allow for variable speed of vertical movement of the component holder and for selective rotation.
