PLACEMENT DEVICE AND ASSEMBLY DEVICE COMPRISING A PLACEMENT DEVICE

摘要

A placement device (100) comprising a gripper (110), a holder (120) and a resilient structure (130). The gripper and the holder are at least moveable relative to each other along a first axis (z), wherein the resilient structure (130) biases the gripper in a reference position relative to the holder by exerting a resultant force in a first direction along the first axis upon a change of the relative position of the gripper opposite to the first direction. The resilient structure comprises a first resilient portion (131) having a relatively low stiffness and a second resilient portion (135) having a relatively high stiffness, the first resilient portion being pretensioned.
