ABSTRACT:
The invention refers to a holding device consisting of holding head and holding shaft for pick-up, transport, and targeted deposit of small components, namely preferably for supplying circuit boards with electrical SMD switching elements.
According to the invention, the holding head is designed so that upon a pressure in the direction of the components to be picked up, a bistable switching element is activated and consequently, the adhesion of the component as well, and upon the next pressure in the same direction, it is again deactivated. This saves specific control actions to activate and deactivate a compressed air source or other adhesive devices.
