Kinematic holding system for a placement head of a placement apparatus

摘要

A kinematic holding system for a placement head of a placement apparatus comprises a placement head alignment device which comprises at least one length-variable holding member arranged at a distance from a joint between a placement head support and the placement head. This holding member determines the pivoting position of the placement head relative to the placement head support. The length of the holding member is changeable during the placement operation depending on a deformation of the placement head guide device caused by the pressing force of the placement head against the substrate in such a way that an axis error (tilt) of the placement head caused by the deformation of the placement head guide device is compensated.

主权项

1. Kinematic holding system for a placement head of a placement apparatus for mounting electronic or optical components on a substrate, comprising:
a placement head guide device comprising a placement head support for holding the placement head; and a placement head alignment device for adjusting the alignment of the placement head relative to the placement head support, wherein the placement head alignment device comprises a joint via which the placement head is supported in an inclination-adjustable way on the placement head support, and wherein the placement head alignment device comprises at least one length-variable holding member which is arranged at a distance from the joint between the placement head support and the placement head and which determines a pivoting position of the placement head relative to the placement head support and whose length is changeable during the placement operation depending on a deformation of the placement head guide device caused by a pressing force of the placement head against the substrate in such a way that an axis error of the placement head caused by the deformation of the placement head guide device is compensated.
