Abstract
A pressure head (10) for contacting a workpiece (230) through relative movement in the vertical Z-direction includes a frame (20), a horn (100) for contacting the workpiece (230) and a gimbal (40) connected to the frame (20). The gimbal (40) supports the horn (100) such that the horn (100) can rotate about orthogonal X and Y rotation axes and can translate in the Z-direction relative to the frame (20). Three adjustment arms (170) movably connected to the frame (20) each apply a force on the horn (100) at points determining a plane for rotating the horn (100) about the X-axis or the Y-axis to a fixed position before contact with the workpiece (230). The adjustment arms (170) also provide electrical connection to electrical devices (136, 138) on the horn (100). A movable contact arm (190) connected to the frame (20) also contacts the horn (100) for providing an electrical connection.
